Description

Technical Field

[0001] The utility model relates to the technical field of firearms, in particular to a plastic flash cap anti-disassembly structure. Background Art

[0002] In the electric airsoft gun market, airsoft guns exported abroad have different legal requirements for flash caps, because once disassembled, they cannot be exported abroad. In order to prevent the flash cap from being loosened or automatically disassembled after a collision, most of them are fixed with pins on the outside of the plastic flash cap, or fixed with glue, which makes it inconvenient for users to replace the required flash cap by themselves. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a plastic primer anti-disassembly structure, which is more reliable in fixation and convenient for users to replace the required primer by themselves.

[0004] The purpose of the utility model is achieved in this way:

[0005] A plastic primer anti-disassembly structure comprises a plastic primer and an outer tube assembly, wherein the outer tube assembly comprises an outer tube and an aligner seat, the aligner seat is fixed to the outer tube by an aligner seat fixing pin, a mounting circular hole is arranged at the front end of the aligner seat, a spring and a primer fixing pin are arranged in the mounting circular hole, a thread is arranged at the front end of the outer tube, the plastic primer cooperates with the thread at the front end of the outer tube, a U-shaped groove is arranged at the rear end of the plastic primer, and the primer fixing pin is stuck in the U-shaped groove of the plastic primer under the action of the spring to form circumferential positioning of the plastic primer.

[0006] Preferably, a limit pin is provided laterally between the front sight and the outer tube, a limit groove is provided on the primer fixing pin, the top of the limit pin is embedded in the limit groove, and the primer fixing pin cooperates with the limit groove to limit the stroke of the primer fixing pin.

[0007] Preferably, a positioning pin is sleeved inside the spring, and the positioning pin is used to limit the stroke of the primer fixing pin.

[0008] Preferably, the flash cap fixing pin maintains the axial positioning of the plastic flash cap within the travel range.

[0009] Preferably, the plastic flash hider is made of injection molding material.

[0010] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0011] Based on the original structure (the structure of the BB soft air gun remains unchanged), through the limiting groove of the flash cap fixing pin, the plastic flash cap cannot be removed by hand regardless of whether the flash cap fixing pin is pressed or not. The plastic flash cap can only be removed by removing the flash cap fixing pin with tools.

[0012] The spring is set to ensure that the original structure remains unchanged, because customers will replace the original flash cap fixing pin and steel flash cap after receiving the airsoft gun. The original flash cap fixing pin does not need a spring, and its length is equivalent to the installation length of the spring and the flash cap fixing pin in the utility model. The utility model can meet export requirements at a low cost. After receiving the product, users can replace the flash cap fixing pin and steel flash cap as needed without changing the original structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1 , Figure 2 A plastic primer anti-disassembly structure comprises a plastic primer, a primer fixing pin, a fixing pin, a spring and an outer tube assembly, wherein the outer tube assembly comprises an outer tube, an aligner seat and an aligner seat fixing pin, a thread is arranged at the front end of the outer tube, the aligner seat is fixed to the outer tube by the aligner seat fixing pin, the spring and the primer fixing pin are arranged in the aligner seat mounting circular hole, the plastic primer is arranged as an injection molding material, the inner hole is arranged with a thread, which is combined with the thread at the front end of the outer tube, the primer fixing pin is inserted into the U-shaped groove of the plastic primer under the action of the spring, the fixing pin is arranged in the matching drill holes of the outer tube and the aligner seat, and in the limiting groove of the primer fixing pin, and the primer fixing pin can be moved forward and backward by pressing.

[0019] Furthermore, a circular hole is provided at the front end of the front sight, which is not a through hole and is used to set a spring and a flash cap fixing pin. The spring is provided to ensure that the original structure remains unchanged, because the customer will replace the flash cap fixing pin and steel flash cap of the original structure after receiving the soft air gun.

[0020] Furthermore, the plastic flash hider is configured to be an injection molding material, because foreign laws require the color of the flash hider, and the color adjustment of the injection molding material is more optimized than the process of the steel material, and it is also cost-effective.

[0021] Furthermore, a limiting groove is provided on the primer fixing pin, and the length of the limiting groove cannot be too long. When the primer fixing pin is pressed, the primer fixing pin cannot be lower than the plane of the sight constellation, and the plastic primer cannot be rotated out to prevent the plastic primer from falling off during transportation.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] When implementing:

[0024] As shown in the figure, a plastic primer anti-disassembly structure includes a plastic primer, a primer fixing pin, a fixing pin, a spring, and an outer tube assembly.

[0025] The outer tube assembly includes an outer tube 2, a quasi-base 6, and a quasi-base fixing pin 7. The quasi-base 6 is fixed to the outer tube 2 by the quasi-base fixing pin 7. The front end of the outer tube 2 is provided with a thread for installing a plastic flash cap 1. The front end of the quasi-base 6 is provided with a mounting circular hole, which is a blind hole, not a through hole, for setting a spring 5 and a flash cap fixing pin 3. The spring 5 is provided to ensure that the original structure remains unchanged, because the customer will replace the flash cap fixing pin and the steel flash cap of the original structure after receiving the soft air gun. The original flash cap fixing pin does not need a spring, and its length is equivalent to the installation length of the spring 5 and the flash cap fixing pin 3. The utility model can meet export requirements at a low cost. After receiving the product, the user can replace the flash cap fixing pin and the steel flash cap as needed without changing the original structure.

[0026] The plastic flash cap 1 is set to be an injection molding material because foreign laws require the color of the flash cap. The color adjustment of the injection molding material is more optimized than the process of steel material, and it is also inexpensive and of good quality. The inner hole of the plastic flash cap 1 is provided with a thread and is combined with the outer tube 2 through a thread. A U-shaped groove 101 is provided at the rear of the plastic flash cap 1. The flash cap fixing pin 3 is inserted into the U-shaped groove 101 of the plastic flash cap 1 under the action of the spring 5. The limit pin 4 is set in the matching drilled holes of the outer tube 2 and the front sight 6, as well as the limit groove 301 of the flash cap fixing pin 3. Pressing the flash cap fixing pin 3 can move forward and backward.

[0027] The primer fixing pin 3 is provided with a limiting groove 301, and the length of the limiting groove 301 cannot be too long. When pressing the primer fixing pin 3, the primer fixing pin 3 cannot be lower than the plane of the quasi-constellation, and the plastic primer 1 cannot be rotated out.

[0028] The same type of structure can be executed with reference to this structure. If the primer fixing pin is set as a cylindrical pin, a cylindrical pin (locating pin) can also be added inside the spring to press the primer fixing pin. The cylindrical pin will limit the axial position of the primer fixing pin, and the plastic primer will not be removed by hand.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
