Detailed Description
In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
As shown in fig. 1-3, the present invention provides a tactical accessory improvement device, which is installed at the end of a gun, and comprises: folding mechanism 1, support core 2 and the butt 3 of cover on supporting core 2, seted up spout 21 on supporting core 2, butt 3 inboard be provided with spout complex slider for butt 3 can slide along spout 21, and is flexible around realizing through sliding, and the front end of support core 2 links to each other with folding mechanism 1 in order to be used for making butt 3 fold to the side of rifle.
As shown in fig. 2, the bottom of the holder core 2 is provided with a plurality of first positioning grooves 22, the gun stock 3 is provided with a positioning device matched with the first positioning grooves 22, the positioning device comprises a positioning pin 31 embedded in the first positioning groove 22 and a shift button 32 used for releasing the positioning pin 31, the front end of the shift button 32 is provided with a button head 321, the positioning pin 31 is connected with the top of the button head 321, and the positioning pin 31 is provided with a return spring 33 used for enabling the positioning pin 31 to be embedded in the first positioning groove 22 through elastic force.
Preferably, the number of the first positioning grooves 22 is not less than 3, and the number of the first positioning grooves 3 in the embodiment is 6, so that the stock can extend and retract in 1-6 steps.
The extension process of the gun stock is
The shift button 32 is pressed, the positioning pin 31 is separated from the first positioning groove 22, the gun stock 3 is dragged to slide backwards to achieve extension, the shift button 32 is released after the gun stock is adjusted to a proper length and is aligned with the nearest first positioning groove 22, the reset spring 33 enables the positioning pin 31 to be embedded into the close first positioning groove 22 through elasticity to achieve locking, and the shortening process of the gun stock is the same.
In order to lock the gun stock after being folded/unfolded in place, as shown in fig. 4, a positioning portion 131 is disposed at the bottom of the rotating shaft 13, and a second positioning slot 112 cooperating with the positioning portion 131 is disposed on the fixing portion 11 for locking the gun stock 3 after being rotated to the folded/unfolded position. For convenience of use, a spring is provided in the rotary shaft 13 for providing an elastic force to fit the positioning portion 131 into the second positioning groove 112 when the butt is folded/unfolded in place.
As shown in fig. 5, the limiting block 111 is provided with a tenon 113, the rotating part 12 is provided with a tenon 121 matched with the tenon 113 for locking after the butt 3 rotates to the unfolding position, and the tenon 121 matched with the tenon 113 in this embodiment is all an inclined tenon. In order to maintain the stability during shooting, when the gunstock is unfolded, the joint surfaces of the limiting block 111 and the rotating part 12 and the joint surfaces of the concave tenon 113 and the convex tenon 12 are all tightly attached.
The folding/unfolding process of the tactical accessory modified device is as follows:
when the stock is unfolded, the left hand holds the gun, the rotating shaft 13 is pressed by the thumb of the right hand to lift the core 2 upwards, the positioning part 131 leaves the second positioning groove 112 in the short stroke upwards moving process, the mutually meshed tenon 121 and the mortise 113 are released simultaneously, the lateral folding can be carried out, and after the folding in place, the positioning part 131 enters the second positioning groove 112 in the short stroke downwards moving process, so that the locking of the stock after the folding in place is realized.
When the butt is folded and locked, the right hand holds the gun, the left hand holds the support core 2, the thumb jacks up the rotating shaft 13, the positioning part 131 leaves the second positioning groove 112 in the short-stroke upward movement process at the moment, the rotating offset action of the spreading of the butt can be carried out, when the butt is offset in place, the spring in the rotating shaft 13 automatically jacks the rotating shaft 13 into the positioning area for accurate positioning, meanwhile, the tenon 121 and the tenon 113 can be occluded and interlocked, and the stable and reliable locking of the butt is realized through the inclined plane compensation gap.
When shooting, the shooter can not correctly press the shoulder and cheek, which can cause deviation of the projectile.
