[0001] This utility model relates to the field of air gun technology, and in particular to a trigger box structure for a bolt-action air gun. Background Technology

[0002] Bolt-action air guns on the market, such as those described in the background technology of utility model CN218511578U, generally include a cylinder locking lever, trigger, cylinder locking push rod, housing top beam, housing top beam spring, main spring, cylinder inner core, spring tube positive pin, handle, handle lock head, adjusting cone head, cylinder locking lever torsion spring, pin, left housing plate, right housing plate, etc. Among them, the housing top beam is used to fix the housing top beam spring, cylinder locking push rod, and cylinder locking lever. However, such housing top beams are prone to jamming when moving, causing the piston body to be unable to be delivered, resulting in abnormal firing function. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a trigger box structure for a bolt-action air gun, which avoids the problem of the trigger box top beam easily getting stuck when it moves by omitting the top beam.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This utility model provides a trigger box structure for a bolt-action air rifle, including a protective case and a trigger, trigger linkage, air cylinder retainer, and elastic reset assembly assembled in the protective case; the trigger, trigger linkage, and air cylinder retainer are rotatably configured, and the air cylinder retainer is used to restrict the movement of the air cylinder; one end of the trigger linkage is connected to the air cylinder retainer, and the other end of the trigger linkage is connected to the trigger; the elastic reset assembly applies elastic force to restrict the trigger, trigger linkage, and air cylinder retainer respectively, forming a multi-link configuration.

[0006] Furthermore, the elastic reset assembly includes a torsion spring, a first spring, and a second spring; the torsion spring is disposed between the air cylinder clamp and the housing; the first spring is disposed between the trigger linkage and the housing; and the second spring is disposed between the trigger and the housing.

[0007] Furthermore, two torsion springs are provided, and the two torsion springs are located on both sides of the air cylinder clamp.

[0008] Furthermore, the trigger linkage has an abutment portion, a protruding portion, and a connecting portion connecting the abutment portion and the protruding portion. The abutment portion is used to abut against the end of the air cylinder clamp that is away from the air cylinder, and the protruding portion is inserted into the trigger.

[0009] Furthermore, one end of the trigger that extends into the housing has a slot that engages with the protruding post, and the protruding post is inserted into the slot.

[0010] Furthermore, the abutting part is provided with an arc-shaped groove on the side facing the air cylinder clamp, and the end of the air cylinder clamp opposite to the air cylinder is provided with an arc-shaped surface that matches the arc-shaped groove.

[0011] Furthermore, the trigger linkage is L-shaped.

[0012] Furthermore, the protective case includes a left protective case panel and a right protective case panel that fit together, and the trigger, the trigger linkage and the air pump clamp are rotatably mounted in the mounting groove of the left protective case panel.

[0013] The technical solution provided by this utility model has the following beneficial effects:

[0014] When the trigger is pulled, the trigger drives the trigger linkage, causing the trigger linkage to disengage from the air cylinder retainer, thereby ensuring that the air cylinder is freed from the restriction of the air cylinder retainer and completing the firing function. Therefore, this utility model can omit the top beam of the housing in the prior art, so as to avoid the phenomenon that the top beam of the housing is easy to jam when it moves. This ensures that the piston body can be reliably delivered and the firing function is normal. At the same time, its structure is simple, strong and sturdy and easy to assemble.

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 6 This embodiment provides a trigger box structure for a bolt-action air gun, including a housing 10 and a trigger 1, a trigger linkage 2, an air cylinder retainer 5, and an elastic reset assembly mounted on the housing 10. Specifically, the housing 10 includes a left housing plate 3 and a right housing plate 4 that cover each other. The trigger 1, the trigger linkage 2, and the air cylinder retainer 5 are rotatably mounted in the mounting slots of the left housing plate 3 through a pivot column structure. The air cylinder retainer 5 is used to restrict the movement of the air cylinder. The front end of the trigger linkage 2 is connected to the air cylinder retainer 5, and the rear end of the trigger linkage 2 is connected to the trigger 1.

[0024] The elastic reset assembly applies elastic force to the trigger 1, trigger linkage 2 and air cylinder clamp 5 respectively to form a multi-link configuration.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the specific elastic reset assembly includes two torsion springs 8, one first spring 6, and one second spring 7. Two torsion springs 8 are provided between the air pump clamp 5 and the housing 10, and the two torsion springs 8 are located on the left and right sides of the air pump clamp 5, respectively. A first spring 6 is provided between the trigger linkage 2 and the left piece of the housing 3, and a second spring 7 is provided between the trigger 1 and the left piece of the housing 3, so that the trigger 1, the trigger linkage 2, and the air pump clamp 5 can be reset under the action of elastic force when the external force is released.

[0026] like Figure 5 The trigger linkage 2 shown has an abutment portion 211, a protruding portion 213, and a connecting portion 214 connecting the abutment portion 211 and the protruding portion 213. The trigger linkage 2 is L-shaped. The abutment portion 211 abuts against the lower end of the air cylinder catch 5 away from the air cylinder. The protruding portion 213 is inserted into the trigger 1. Specifically, as shown... Figure 4 The upper end of the trigger 1 shown has a slot 172 for a mating protrusion 213. The protrusion 213 is inserted into the slot 172 to achieve a reliable connection between the trigger 1 and the trigger linkage 2.

[0027] In specific implementation, such as Figures 2 to 6As shown, the trigger 1 is installed in the first mating position of the left cover plate 3, and the trigger linkage 2 is installed in the second mating position of the left cover plate 3. At this time, the pivot post 212 of the trigger linkage 2 mates with the hole 236 of the left cover plate 3, the U-shaped hole 234 of the left cover plate 3 mates with the protrusion 173 of the trigger 1, the shaft hole 235 of the left cover plate 3 mates with the pivot post 171 of the trigger 1, and the slot hole 172 of the trigger 1 mates with the protrusion 213 of the trigger linkage 2. Simultaneously, the first spring 6 is installed between the first recess 232 of the left cover plate 3 and the connecting part 214 of the trigger linkage 2, and the second spring 7 is installed between the second recess 233 of the left cover plate 3 and the protrusion 174 of the trigger 1. Then, the two torsion springs 8 and the air pump clip 5 are installed in the mounting hole 231 of the left cover plate 3 by means of the pin 9. Finally, the right cover plate 4 is covered with the left cover plate 3.

[0028] When the trigger 1 is not pulled, the trigger 1 is lifted and rotated by the elastic force of the second spring 7, which drives the trigger linkage 2 to move accordingly, so that the abutment part 211 of the trigger linkage 2 always abuts against the lower end of the air pump clamp 5, thereby counteracting the elastic force restriction of the torsion spring 8, thus ensuring that the air pump clamp 5 is stationary and does not rotate. At this time, the air pump clamp 5 can also restrict the movement of the air pump.

[0029] When trigger 1 is pulled, trigger 1 drives trigger linkage 2, causing trigger linkage 2 to disengage from the air cylinder retainer 5, thereby ensuring that the air cylinder is freed from the restriction of the air cylinder retainer 5 and completing the firing function. Therefore, this embodiment can omit the top beam of the protective case in the prior art to avoid the phenomenon of easy jamming when the top beam of the protective case moves, thus ensuring that the piston body can be reliably delivered and the firing function is normal. At the same time, its structure is simple, strong and convenient to assemble.

[0030] Of course, in other embodiments, the number of torsion springs 8 may also be one.

[0031] Further preferred, such as Figure 1 and Figure 5 As shown, the abutment part 211 is provided with an arc-shaped groove 215 facing the front side of the air cylinder clamp 5, and the lower end of the air cylinder clamp 5 is provided with an arc-shaped surface 51 that matches the arc-shaped groove 215. Therefore, through the mutual cooperation of the arc-shaped groove 215 and the arc-shaped surface 51, it is ensured that the air cylinder clamp 5 and the trigger linkage 2 can move smoothly when the trigger 1 is pulled, and there will be no jamming. At the same time, the wear rate of the air cylinder clamp 5 and the trigger linkage 2 can also be reduced.

[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
