Description
Technical Field
The invention belongs to the technical field of sealing clamps, and particularly relates to a structure technology of a simple vacuum sealing clamp.
Background
The existing sealing clamp in the market is generally of a hairpin type structure and is used for clamping two sides of a film bag, so that the effect of reducing air circulation and further prolonging the preservation period is achieved. This is generally desirable, but has the disadvantages of: firstly, two sides of the sealing clamp do not apply linear force, and the clamping force is not enough! And cannot be used for vacuum sealing. Secondly, two sides of the sealing clamp are not provided with elastic rubber strips with large thickness, and the sealing performance is not good enough! And the sealing state cannot be maintained when the exhaust pipe is inserted or extracted.
Disclosure of Invention
The invention aims to provide a simple vacuum sealing clamp structure which has large clamping force and can keep the sealing state of a film bag when an exhaust tube is inserted or extracted by using an elastic adhesive tape with large thickness.
In order to achieve the purpose, the technical solution of the invention is as follows: a simple vacuum sealing clamp structure is shown in figure 1 and a cross section view 2 and comprises a base, a rotary handle, a connecting column, an elastic rubber strip, a rotary pressing strip, an exhaust tube and a plug. As shown in the sectional views 3 and 4, the base is provided with a shallow groove at the upper part of one side of the section for connecting an elastic rubber strip. The middle bottom of the section of the rotary pressing bar is provided with a circular gap groove for connecting the rotary pressing bar. The bottom of the air pump is provided with a through hole for penetrating through the air suction pipe. The upper part of the other side of the section of the handle is provided with a semicircular ring body (a male structure of a hinged structure) with a semicircular groove for connecting the groove of the rotary handle. It is apparent that there are a number of prior art alternatives to the male configuration of this hinge structure. There are 3 cavitys on the base for strengthen structural force and connect the end cap.
The rotary handle is shown in fig. 5, and one side of the rotary handle is a groove (a female structure of a hinge structure) with a small groove at the inner circle center position. Obviously, there are a number of prior art alternatives to this female structure of the hinge structure. An arc-shaped bulge is arranged at the position which is outside the semicircular ring outside the groove and has an included angle of about 20 degrees with the extension line of the chord vertical to the groove. From the end of the thinner semicircular ring to the arc-shaped bulge, the arc-shaped bulge is connected by an arc with gradually thickened thickness. The other side of the groove is provided with a handle.
The connecting column is a cylinder. Outlined.
The elastic rubber strip is made of rubber or silica gel or plastic as shown in fig. 6, and has two symmetrically arranged strips. The main body of each strip is a rectangular block (or a trapezoidal block or a semicircular block), and two sides of the bottom of each strip are small rectangles and are used for being connected with the shallow grooves of the base or the shallow grooves of the rotary pressing strips. The rectangular blocks of the two elastic adhesive tapes are respectively provided with an arc-shaped notch to form a longitudinal through hole for connecting the air exhaust pipe after compressing the film bag. Obviously, when the diameter of the air exhaust tube is smaller, the longitudinal through hole does not need to be specially manufactured, but the longitudinal through hole can be naturally formed at the position where the air exhaust tube is pressed after the two elastic rubber strips press the film bag.
The bottom of the rotary pressing bar is a cylinder which is used for connecting a round gap groove of the base (can rotate in the groove by a small angle) as shown in figure 7 and a sectional view 8. The upper edge of the groove is a shallow groove for connecting the elastic rubber strip. The other side of the upper part of the handle is connected with a plastic sheet for reducing friction force when the arc-shaped bulge of the rotary handle is extruded. The upper part of the plastic sheet is thinner, and the bottom of the plastic sheet is provided with a lug which is used for being matched with the arc-shaped bulge of the rotary handle to increase the rotating angle of the rotary pressing strip. The upper part of the plastic sheet is connected with the lug through an arc edge (bevel edge) so as to ensure smooth up-down connection.
The suction tube is shown in fig. 9 and a cross section 10, and the main body of the suction tube is a blind tube, and a step is arranged on the blind tube and used for abutting against a rubber pad. The rubber pad is used for sealing. And a thread step is arranged beside the rubber pad and is used for being in threaded connection with an air pipe of an air extractor or an air pumping cylinder. One side of the bottom of the blind pipe is provided with a transverse through hole for pumping air in the film bag. The bottom of the blind pipe is sleeved with a silicone tube, and the transverse through hole is covered to ensure that air can only go out but not enter, so that unidirectional flow is realized. Obviously, when the air pump or the air pump cylinder is provided with the one-way valve, the air pumping pipe only needs to be a simple circular pipe. After the air in the film bag is pumped out, the air pumping pipe with smaller diameter is pumped out from the film bag compressed by the two elastic rubber strips, and the elastic rubber strips can compress the film bag to enable the film bag to be automatically sealed.
The said plug is shown in fig. 11 and 12, and one side of the plug is a cover for covering the two ends of the base for beautification. The inner side of the cover is provided with a bulge for connecting the cavity of the base.
Fig. 13 is a schematic view showing the combination of the base, the swing handle, the connecting column, the elastic rubber strip, the rotary pressing strip and the air suction pipe when the swing handle rotates clockwise by 90 °.
The connection of the base, the rotary handle, the connecting column, the elastic rubber strip, the rotary pressing strip, the exhaust tube and the plug is shown in figure 1 and a cross sectional view 2, the semicircular ring body of the base is connected with the groove of the rotary handle through the connecting column, the circular gap groove is connected with the rotary pressing strip, and the cavity is connected with the plug. The elastic rubber strip is respectively connected with the shallow groove of the base and the shallow groove of the rotary pressing strip. The air suction pipe penetrates through the through hole of the base and the longitudinal through hole between the two elastic rubber strips to enter the film bag.
Obviously, the hinge structure part of the above technical solution can be easily replaced by other existing hinge technology; when the air extractor or the air extracting cylinder is provided with the one-way valve, the air extracting pipe can also be a simple round pipe and is pulled out after air extraction is finished; such a simple substitution should fall within the scope of protection of the present solution.
After the scheme is adopted, the invention has the beneficial effects that: the clamping force is large, and the elastic rubber strip with large thickness is used, so that the sealing state of the film bag can be kept when the air exhaust pipe is inserted or extracted.
