Description

Automatic grenade launcher sight external reticle mounting locking mechanism

Technical Field

The utility model relates to the technical field of automatic grenade launcher sighting scope setting, in particular to an automatic grenade launcher sighting scope external graticule setting locking mechanism, which is suitable for setting long-distance shooting tables of infrared and white light sights.

Background Art

When an automatic grenade launcher is used to attack a target at a long distance, the mechanical sight cannot meet the shooting accuracy requirements. To ensure shooting accuracy, a sight is required for aiming. When shooting at a long distance with an automatic grenade launcher, the sight needs to use both external and internal scales to set the shooting table. In order to solve the technical problem of setting the long-distance shooting table for infrared and white light sights used in automatic grenade launchers, the following two solutions are currently used:

The first is to design a "click value" type locking elevation mechanism between the scope body and the connecting seat through the action of the mechanical structure, and then manually bend the elevation body to set a fixed angle for each gear "click value". Although this "click value" type locking elevation mechanism can make the scope body pitch, the scope body can only move downward without the help of external tools. If you want to return the scope body to its original horizontal position or look up, you need to use tools to loosen the screws on the elevation mechanism, then adjust the position of the scope body, and then tighten the screws to lock and fix the external differentiation of the scope; secondly, this elevation mechanism is prone to wear and debris, which in turn affects the locking effect of the elevation mechanism. After many operations, it is difficult to ensure the shooting accuracy requirements; furthermore, this external differentiation of the scope can only be set or changed at a fixed angle, and cannot flexibly set the required shooting angle.

The second type is a certain type of external differentiated locking mechanism as shown in Figure 1 of the specification. The handle 10 of this locking mechanism is non-fixed and is easy to swing when the weapon is fired, which will cause certain interference to the shooter's shooting; secondly, when the handle 10 and the slotted screw 20 are operated and rotated, the teeth on the slotted screw are easy to break.

Therefore, it is particularly important to design a simple and reliable external scale setting and locking mechanism, so as to improve the shooting accuracy of the automatic grenade launcher and the operability of the sight table setting.

Utility Model Content

The utility model aims to solve the problems of the existing external reticle locking mechanism that the required shooting angle cannot be flexibly set, the handle will interfere with shooting, and the handle is easily damaged. To this end, the utility model provides an automatic grenade launcher sighting scope external reticle locking mechanism with reasonable structural design and simple operation.

The technical solution adopted by the utility model to solve its technical problems is:

Provided is a locking mechanism for fixing the external scale of an automatic grenade launcher sight, comprising an elevation seat, a bracket for mounting a sight and rotatably mounted on the elevation seat through a rotating shaft, a locking assembly arranged in an arc groove of a side plate of the elevation seat and connected to the bracket, and connecting plates at both ends of which are rotatably connected to the elevation seat and the locking assembly; the locking assembly comprises a locking screw, a locking wrench and an elastic assembly, the screw section of the locking screw sequentially passes through the connecting plate and the arc groove and is movably connected to the bracket, the head of the locking screw is provided with a spline groove, one side of the end of the locking wrench is provided with a spline shaft matched with the spline groove, and the elastic assembly is arranged on the other side of the end of the locking wrench, and passes through the locking wrench to be connected with the locking screw.

The locking mechanism adjusts the tilt angle of the bracket through the locking component, and then adjusts the set shooting angle of the sight, which has the advantages of simple and flexible adjustment; the designed locking component uses an elastic component to press the locking wrench onto the locking screw, and at the same time, the locking screw and the locking wrench adopt a structure in which the spline groove and the spline axially cooperate, which can overcome the elastic force of the elastic component and separate, and then the direction of the locking wrench can be adjusted, realizing a fixed structure of the locking wrench with adjustable direction, solving the problem that the traditional non-fixed handle is easy to swing when the weapon is fired, causing certain interference to the shooter's shooting; and when the locking wrench adjusts the angle of the bracket, the spline groove and the spline shaft are completely engaged under the action of the elastic component, and there will be no problem of easy breakage of teeth.

Preferably, a countersunk hole is provided on the other side of the end of the locking wrench, and the elastic component is arranged in the countersunk hole. Such a design can make the elastic component sink into the locking wrench without protruding from the end surface of the locking wrench, which can not only improve the aesthetics of the design, but also protect the elastic component.

In a preferred embodiment, the elastic component includes a plug cover, a spring and a fixing screw. The spring is arranged in the countersunk hole and is sealed by the plug cover. The fixing screw passes through the locking wrench to fix the plug cover on the locking screw.

In a preferred embodiment, a boss with a screw hole is provided in the middle of the spline groove, and the boss extends into the countersunk hole of the locking wrench through the through hole and is connected to the fixing screw. This design enables the boss to have a positioning function, which can improve the assembly accuracy on the one hand, and can also play a guiding role when the locking wrench is adjusted in direction (this operation requires the locking wrench to be separated from the locking screw).

The utility model provides a locking mechanism for fixing the external scale of an automatic grenade launcher sight, as shown in Figures 2 to 7, comprising an elevation seat 1, a bracket 3 for mounting a sight that is rotatably mounted on the elevation seat 1 through a rotating shaft 2, a locking assembly 4 that is arranged in an arc groove of a side plate 1.1 of the elevation seat 1 and connected to the bracket 3, and connecting plates 5 that rotatably connect the elevation seat 1 and the locking assembly 4 at both ends. The sight is mounted on the bracket 3, and the sight is fixed by loosening the locking assembly 4 and adjusting the inclination angle of the bracket 3. After the adjustment, the locking assembly 4 can be locked. In order to solve the problems of inflexible adjustment of the existing locking mechanism and the problem that the non-fixed handle is easy to swing when the weapon is fired, which will cause certain interference to the shooter's shooting, the locking assembly 4 is designed as follows in this embodiment:

As shown in Figures 4 to 6, the locking component 4 includes a locking screw 4.1, a locking wrench 4.2 and an elastic component 4.3. The screw section of the locking screw 4.1 passes through the connecting plate 5 and the arc groove in sequence and is movably connected to the bracket 3. The head of the locking screw 4.1 is provided with a spline groove 4.1.0, and one side of the end of the locking wrench 4.2 is provided with a spline shaft 4.2.1 that cooperates with the spline groove 4.1.0. The elastic component 4.3 is arranged on the other side of the end of the locking wrench 4.2, and passes through the locking wrench 4.2 to be connected with the locking screw 4.1.

The present embodiment adjusts the tilt angle of the bracket 3 and further adjusts the fixed shooting angle of the sight through the locking component 4, which has the advantages of simple and flexible adjustment. The designed locking component 4 uses the elastic component 4.3 to press the locking wrench 4.2 onto the locking screw 4.1. At the same time, the locking screw 4.1 and the locking wrench 4.2 adopt a structure in which the spline groove 4.1.0 and the spline shaft 4.2.1 cooperate, which can overcome the elastic force of the elastic component 4.3 and separate, and further adjust the direction of the locking wrench 4.2, so that the locking wrench 4.2 is a fixed structure with adjustable direction, which solves the problem that the traditional non-fixed handle is easy to swing when the weapon is fired, causing certain interference to the shooter's shooting. When the locking wrench 4.2 adjusts the angle of the bracket 3, the spline groove 4.1.0 and the spline shaft 4.2.1 are completely engaged under the action of the elastic component 4.3, and there will be no problem of easy breakage of teeth.

Preferably, a countersunk hole 4.2.0 is provided on the other side of the end of the locking wrench 4.2, and the elastic component 4.3 is arranged in the countersunk hole 4.2.0. Such a design enables the elastic component 4.3 to sink into the locking wrench 4.2 without protruding from the end surface of the locking wrench 4.2, which not only improves the aesthetics of the design, but also serves the purpose of protecting the elastic component 4.3.

In a preferred embodiment, as shown in Figure 5, the elastic component 4.3 includes a plug cover 4.3.1, a spring 4.3.2 and a fixing screw 4.3.3. The spring 4.3.2 is arranged in the countersunk hole 4.2.0 and is blocked by the plug cover 4.3.1. The fixing screw 4.3.3 passes through the locking wrench 4.2 to fix the plug cover 4.3.1 on the locking screw 4.1.

Furthermore, a boss 4.1.1 with a screw hole is provided in the middle of the spline groove 4.1.0, and the boss 4.1.1 extends into the counterbore 4.2.0 of the locking wrench 4.2 through a through hole and is connected to the fixing screw 4.3.3. This design enables the boss 4.1.1 to have a positioning function, which can improve the assembly accuracy on the one hand, and can also play a guiding role when the locking wrench 4.2 is adjusted in direction (this operation requires the locking wrench 4.3 to be separated from the locking screw 4.1).

Furthermore, the inner ring of the plug cover 4.3.1 is also provided with a guide cylinder 4.3.1.1, and the outer diameter of the guide cylinder 4.3.1.1 is not greater than the inner diameter of the through hole. This design enables the guide cylinder 4.3.1.1 to play a guiding role in the process of adjusting the direction of the locking wrench 4.2.

In a preferred embodiment, as shown in FIG3 and FIG5 , a connecting ear 3.1 is provided on one side of the bracket 3 connected to the locking assembly 4, and the connecting ear 3.1 is threadedly connected to the locking screw 4.1.

Further, as shown in FIG. 5 , a screw sleeve 6 is screwed on the connection ear 3.1, and the screw sleeve 6 is screwed with the locking screw 4.1. A flange plate 6.1 is provided on a side of the screw sleeve 6 close to the side plate 1.1, and the thickness of the flange plate 6.1 is equal to the distance between the side plate 1.1 and the bracket 3. This design utilizes the flange plate 6.1 of the screw sleeve 6 to eliminate the gap between the side plate 1.1 and the bracket 3, thereby preventing the side plate 1.1 from deforming when being locked.

In a preferred embodiment, it also includes a degree disk 30 and/or a photoelectric encoder 40. As shown in Figures 1 and 2 of the specification, the degree disk 30 is arranged on the top of the side plate 1.1, and the connecting plate 5 is also provided with an indication mark (not shown in the figure) for indicating the scale on the degree disk 30. The photoelectric encoder 40 is arranged at the end of the rotating shaft 2 to detect the inclination angle of the bracket 3. In specific implementation, when a white light sight is used, an external scale setting and locking mechanism with a degree disk 30 is selected; when an infrared sight is used, an external scale setting and locking mechanism with a photoelectric encoder 40 is selected, and the set shooting angle is read in the sight using the electrical signal of the photoelectric encoder 40. It is preferred to set the degree disk 30 and the photoelectric encoder 40 at the same time, so that it can simultaneously meet the setting of the infrared and white light sights long-distance shooting tables.

During specific operation, the locking mechanism for setting the external scale of the scope designed in the present application only needs to loosen the locking wrench 4.215°-30° counterclockwise to allow the bracket 3 and the scope mounted thereon to be set to the required shooting angle value up and down. After the shooting angle value is set, it only needs to be pre-tightened 15°-30° clockwise.

Taking into account the human-machine adaptability, after pre-tightening the locking wrench 4.2, if the locking wrench 4.2 is facing the side of the person's face in the sight, the locking wrench 4.2 can be lifted out to disengage it from the locking screw 4.1, and the locking wrench 4.2 can be rotated counterclockwise to avoid it from aligning with the person's face.

When disassembly is required, the pitch angle of the bracket 3 is adjusted to the maximum, at which time the locking wrench 4.2 can be rotated a full circle, and the locking assembly 4 can be quickly removed.

The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
