Description

Opening and anti-rebound mechanism of cabin door

The technical field is as follows:

the utility model relates to an aerospace product manufacturing technology field, in particular to cube star separator's hatch door open and prevent bounce-back mechanism.

Background art:

the hatch opening and anti-bounce structure is generally integrated in various devices containing hatches for use, and has the main functions of limiting the maximum opening angle of the hatch and preventing the bounce phenomenon after the hatch is opened.

Some existing similar mechanisms are provided with male and female hook-and-loop fasteners arranged on the back of the cabin door and the baffle, so that the cabin door can be locked after being opened in place, the cabin door does not rebound any more, the functionality of the cabin door is easy to lose effectiveness due to the influence of the environment in a mode of arranging the male and female hook-and-loop fasteners or a similar mode, and the structure is easy to lose effectiveness when the bounce of the cabin door is larger.

And a locking pin and a leaf spring mechanism are adopted, and the locking pin can enter the round hole of the leaf spring through impact to lock the cabin door.

Or an arc-shaped support and a spring support roller mechanism are adopted, the cabin door drives the arc-shaped support to move together, and when the cabin door moves in place, the spring pushes the roller to abut against the other end of the arc-shaped support, so that the arc-shaped support cannot move back, and the reverse motion of the cabin door is prevented.

However, in the existing part of anti-bouncing devices for the hatches, in order to realize the function, a plurality of component products are additionally arranged for assembly, the structure is often complex, the appearance of the product is irregular, and the use space of the product is limited.

The utility model has the following contents:

the utility model aims at providing an opening and preventing mechanism that bounces of hatch door, it is simple reliable, use realize opening and preventing the bounces of hatch door among the separator in cube star separator.

The above purpose is realized by the following technical scheme:

an opening and anti-rebounding mechanism for a cabin door comprises: hatch door, end frame, the hatch door on install the hinge, the end frame on have a hatch door axle mounting, hatch door axle mounting on have the spacing hole of end frame, the hatch door axle passes in proper order the spacing hole of end frame hinge, torsional spring, the one end of torsional spring compress tightly through big clamp plate the end frame on, the other end of torsional spring compress tightly through little clamp plate the hatch door on, extension spring one end is fixed the end frame on in the recess, the extension spring other end fix the cabin door epaxial, the end frame on have the right angle step groove.

The position and the size of the right-angle step groove correspond to the hinge.

The utility model has the advantages that:

the utility model discloses only need add two extension spring and can realize preventing the bounce-back function of hatch door in step on necessary spare part basis is opened to the hatch door, be favorable to the product integration. The whole structure is simple, the manufacture is easy, and the cost is low. The structure has wide application range, strong practicability and high reliability.

The specific implementation mode is as follows:

to make the structure and advantages of the present invention clearer, the present invention will be described more clearly and completely with reference to the attached drawings in the following embodiments. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1:

as shown in fig. 1, an opening and anti-rebounding mechanism for a hatch comprises: hatch door 1, end frame 2, extension spring 3, big clamp plate 4, torsional spring 5, hatch door axle 6, hinge 7, little clamp plate 8, the spacing hole of hatch door axle mounting 9, end frame 10, the hatch door on install the hinge, the end frame on have hatch door axle mounting, hatch door axle mounting on have the spacing hole of end frame, the spacing hole of end frame be the elongated hole, the hatch door axle passes in proper order the spacing hole of end frame hinge, torsional spring, the one end of torsional spring compress tightly on the end frame through big clamp plate, the other end of torsional spring compress tightly on the hatch door through little clamp plate, extension spring one end is fixed in the recess on the end frame, the extension spring other end fix the hatch door epaxially, the end frame on have a right angle step groove, the mounted position and the size of right angle step groove and hinge correspond.

The assembling process comprises the following steps: firstly, a hinge 7 is installed on a cabin door 1, a mounting hole is reserved in a part to be convenient for locking by a bolt, a cabin door shaft 6 sequentially penetrates through an end frame limiting hole, the hinge 7 and a torsion spring 5, the torsion spring 5 is respectively pressed on the cabin door 1 and the end frame 2 by a small pressing plate 8 and a large pressing plate 4, and finally one end of an extension spring 3 is fixed in the end frame, and the other end of the extension spring is fixed on the cabin door shaft 6.

The working principle is as follows: the acting force of the torsion spring 5 drives the cabin door 1 to rotate around the cabin door shaft 6 to be opened, after the cabin door 1 is opened and rotates to a certain angle, the extension spring 3 pulls the cabin door assembly, so that the hinge 7 is meshed with the right-angled step of the end frame 2 to limit the cabin door 1, and therefore the anti-rebound function of the cabin door is achieved.

Example 2:

according to the opening and anti-rebounding mechanism of the cabin door described in embodiment 1, when the cabin door is closed, as shown in fig. 1, the mechanism receives the acting force of the torsion spring 5, which is the opening power of the cabin door 1, and simultaneously receives the vertical pulling force of the extension springs 3 at the two ends, but at this time, the horizontal hinge 7 is in contact with the surface of the end frame 2, and the cabin door 1 is in contact with the surface of the end frame 2, so that the vertical force of the mechanism is balanced.

When the hatch door is opened, hatch door 1 rotates certain angle under the drive of torsional spring 5, when hatch door 1 moves to the state of fig. 3, hinge 7 meets with the right angle step portion of end frame 2, the hinge loses the contact with the end frame, subsequently, as shown in fig. 5, the hatch door subassembly (by hatch door 1, hinge 7, torsional spring 5, the whole of cabin door axle 6 constitution) can be under extension spring 3's effect, wholly move certain displacement to end frame 2 direction, hinge 7's step department can with the interlock of 2 steps of end frame, thereby spacing hatch door 1, make hatch door 1 can't continue the rotation and open, also can't kick-back, realize preventing the hatch door bounce-back function.

as shown in fig. 6, the maximum opening angle α of the door 1 can be controlled, and the maximum opening angle α of the door 1 can be determined by the angle β between the large end surface of the door 1 and the step surface of the hinge 7 after the door 1 is assembled with the hinge 7, and by structural analysis, α = 270 ° - β can be obtained.

When the cabin door is opened to a closed state, the cabin door 1 needs to be lifted outwards, the hinge 7 is separated from the right-angle stepped groove of the end frame 2, the limit of the stepped groove of the end frame on the cabin door is eliminated, and then the cabin door 1 rotates around the cabin door shaft 6 to the closed state of the cabin door, so that the aim of closing the door is fulfilled.

The embodiments of the present invention have been described in detail. It is to be understood that the present invention is not limited to the specific embodiments described above, and that modifications to the embodiments described above may be made by those skilled in the art without affecting the spirit of the present invention.
