Description

Technical Field

[0001] The utility model relates to the technical field of gun calibration, in particular to a gun auxiliary calibration bracket. Background Art

[0002] The four-point aiming bracket is supported by a rectangular annular frame, and a butt bracket and a muzzle bracket are provided to connect and position the butt and muzzle of the firearm. The bottom of the butt bracket of the four-point aiming bracket is parallel to one frame of the annular frame, and the butt bracket slides on the annular frame along the frame direction of the annular frame, and the annular frame is threaded with a tightening screw to tighten and position the butt bracket. When adjusting the horizontal and lateral position of the butt bracket, the personnel must first loosen the tightening screw and then tap the butt bracket to adjust the horizontal and lateral position of the butt bracket. After the adjustment is completed, the tightening screw must be re-tightened to position the butt bracket, thereby completing the adjustment of the horizontal and lateral shooting angle of the firearm. At the same time, the personnel can use the height adjustment mechanism composed of bolts and nuts to accurately adjust the vertical shooting angle of the firearm. Thus, the calibration of the firearm aiming structure is completed with the cooperation of the reference point.

[0003] When personnel adjust the horizontal and lateral shooting angle of a firearm by knocking on the butt support, the amount of adjustment of the horizontal and lateral shooting angle of the firearm by personnel will undoubtedly be different each time, that is, the accuracy of adjusting the horizontal and lateral shooting angle of the firearm by personnel is low, so personnel need to knock on the butt support multiple times with different intensities to complete the accurate adjustment of the horizontal and lateral shooting angle of the firearm, that is, it takes a long calibration time and a large number of knocks to complete the calibration of the firearm aiming structure. Knocking to adjust the horizontal and lateral shooting angle of a firearm will reduce the accuracy of personnel calibrating the firearm aiming structure, and will also reduce the efficiency of personnel calibrating the firearm aiming structure. Utility Model Content

[0004] The utility model aims to provide a firearm auxiliary calibration bracket to assist personnel in accurately and quickly adjusting the horizontal lateral shooting angle of the firearm.

[0005] In order to solve the above technical problems, the specific solution adopted by the utility model is:

[0006] A firearm auxiliary calibration bracket comprises a base, a muzzle bracket and a butt bracket which are arranged on the base at intervals. The butt bracket comprises a butt clamp, which is connected to the base through a height adjustment mechanism and a horizontal adjustment mechanism. The horizontal adjustment mechanism comprises a sliding rail, in which an adjustment stud is rotatably connected, and the adjustment stud is threadedly connected to a sliding screw block which slides in the sliding rail, and the butt clamp is fixed on the sliding screw block.

[0007] As a further optimization of the firearm auxiliary calibration bracket of the utility model, the base is a rectangular storage box, the muzzle bracket and the butt bracket are rotatably connected at both ends of the storage box respectively, and the storage cavity of the storage box is used to store the muzzle bracket and the butt bracket after relative rotation.

[0008] As a further optimization of the firearm auxiliary calibration bracket of the utility model, the base is provided with support bars at both ends that pass downward over the base near the muzzle bracket, and a fixed-point column is provided on the bottom surface of the base near the butt bracket, and the two ends of the support bar and the bottom end of the fixed-point column form a triangular structure for supporting the base.

[0009] As a further optimization of the firearm auxiliary calibration bracket of the utility model, a plug-in slot for disassembling and assembling the support strip is provided at the base near the muzzle bracket.

[0010] As a further optimization of the firearm auxiliary calibration bracket of the utility model, the butt clamp includes a U-shaped frame fixedly connected to the sliding screw block, and both vertical side walls of the U-shaped frame are threadedly connected with clamping studs, and the clamping studs are rotatably connected to one end of the U-shaped frame with a clamping plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model sets the adjustment stud included in the horizontal adjustment mechanism to make the sliding screw block slide horizontally in the sliding rail, thereby driving the gun stock clamp fixed to the sliding screw block to move horizontally and laterally. After the gun stock clamp moves horizontally and laterally, it will drive the gun stock connected to the gun stock clamp to move horizontally and laterally, that is, the horizontal and horizontal shooting angle of the firearm is accurately adjusted. After the personnel can accurately adjust the horizontal and horizontal shooting angle of the firearm, the number of times the personnel adjust the horizontal and horizontal shooting angle of the firearm will be reduced, thereby enabling the personnel to quickly adjust the horizontal and horizontal shooting angle of the firearm. After the horizontal and vertical shooting angles of the firearm are adjusted, the personnel can use the corresponding reference points to complete the calibration of the firearm aiming structure.

[0013] As a further optimization of the present invention, the present invention forms a triangular structure for support at the bottom of the base by setting support bars and fixed-point columns, thereby stably positioning the base, that is, keeping the position of the firearm stable during the firearm calibration process, thereby assisting personnel in firearm calibration. Compared with the annular frame of the four-point aiming bracket, the triangular structure can adapt to more complex terrain to stably place the base, and can also reduce the occupied space to a certain extent.

[0014] As a further optimization of the present invention, the present invention provides a storage box with a rectangular base to store the muzzle bracket and the butt bracket after relative rotation, thereby facilitating the carrying and transfer of personnel, and also facilitating the storage and placement of personnel. At the same time, a plug-in slot is provided for the support bar to be disassembled, so that when carrying, transferring or storing the bracket, the size of the base can be reduced to facilitate carrying or stacking and storage. The support bar can be inserted into the gap between the storage box and the muzzle bracket and the butt bracket, thereby reducing the probability of the support bar being lost on the basis of facilitating the carrying and storage of personnel.

DETAILED DESCRIPTION

[0021] like Figure 1 and Figure 2 As shown, the utility model includes a base 1, a muzzle bracket 2 arranged on the left side of the base 1, and a butt bracket 3 arranged on the right side of the base 1. The muzzle bracket 2 and the butt bracket 3 can connect the muzzle and the butt of the firearm, and then cooperate with the base 1 to position the firearm, so as to assist personnel in calibrating the firearm aiming structure.

[0022] like Figure 5As shown, the muzzle bracket 2 includes a supporting bracket 201 arranged on the left side of the base 1, and a crab claw clamp 202 is fixedly connected to the top of the supporting bracket 201. The crab claw clamp 202 can facilitate personnel to adjust the size of the crab claw clamp 202 as needed, thereby facilitating personnel to connect the muzzles of firearms of different calibers within a certain range.

[0023] like Figure 1 and Figure 2 As shown, the butt support 3 includes a height adjustment mechanism 303 and a horizontal adjustment mechanism 302. The height adjustment mechanism 303 can assist personnel in adjusting the vertical shooting angle of the firearm, and the horizontal adjustment mechanism 302 can assist personnel in adjusting the horizontal lateral shooting angle of the firearm, thereby assisting personnel in calibrating the firearm aiming structure.

[0024] The height adjustment mechanism 303 is composed of a nut sleeve fixed on a support frame and a threaded column matched with the nut sleeve, and the axial rotation of the threaded column is limited by the support frame. A person can rotate the nut sleeve to raise or lower the threaded column, and when the threaded column is raised or lowered, the butt support 3 can be extended or retracted to change the height position of the butt, thereby adjusting the vertical shooting angle of the firearm.

[0025] like Figure 3 and Figure 4 As shown, the horizontal adjustment mechanism 302 includes a sliding rail 3023, and the adjustment stud 3022 is threadedly connected to the sliding screw 3021 sliding in the sliding rail 3023. When the pitch of the adjustment stud 3022 is determined, each rotation of the adjustment stud 3022 can make the sliding screw 3021 move the same amount, so that it is convenient for personnel to control the required amount of horizontal lateral movement of the sliding screw 3021, that is, to accurately adjust the position of the sliding screw 3021. The bottom end of the sliding rail 3023 is fixedly connected to the top end of the threaded column, and the upper side of the sliding screw 3021 is fixedly connected with the butt clamp 301, so that it is convenient for personnel to accurately adjust the vertical and horizontal positions of the butt clamp 301, that is, to accurately adjust the vertical and horizontal shooting angles of the firearm.

[0026] The gun stock clamp 301 comprises a U-shaped frame 3011 fixedly connected to a sliding screw block 3021, and both vertical side walls of the U-shaped frame 3011 are threadedly connected with clamping studs 3012, one end of the clamping stud 3012 is rotatably connected with a clamping plate 3013 for clamping the gun stock, and the other end of the clamping stud 3012 is fixed with a gripping member 3014. Thus, a person can use the gripping member 3014 to drive the clamping stud 3012 to rotate, thereby causing the clamping plate 3013 to clamp the gun stock.

[0027] The left side of the base 1 is provided with a support bar 102 whose two ends extend downwardly beyond the bottom surface of the base 1, and a fixed column 104 is fixedly connected to the bottom surface of the base 1 facing the butt support 3. The fixed column 104 can be a screw with a conical bottom end, which is then connected to the corresponding screw hole opened on the base 1, and then the fixed column 104 can be rotated to adjust the position of the bottom end of the fixed column 104, and then the bottom end of the fixed column 104 and the two ends of the support bar 102 can form a triangle relatively horizontal to the ground. The fixed column 104 can also be directly welded to the bottom surface of the base 1, and then the bottom end of the fixed column 104 and the two ends of the support bar 102 can form a triangle relatively horizontal to the ground. The triangle relatively horizontal to the ground can facilitate personnel to stably place the base 1 on the ground for use, that is, to facilitate personnel to stably place the firearm on the ground, thereby assisting personnel in calibrating the firearm aiming structure.

[0028] The base 1 is a rectangular storage box 101, and a plug-in slot 103 for disassembling and assembling the support bar 102 is provided on the left side of the storage box 101. The muzzle bracket 2 and the butt bracket 3 are both rotatably connected to the storage box 101, and after the rectangular storage box 101 stores the relatively rotating muzzle bracket 2 and the butt bracket 3, there is a gap between the inner wall of the storage box 101 and the muzzle bracket 2 and the butt bracket 3. After the personnel complete the firearm calibration, the muzzle bracket 2 and the butt bracket 3 can be relatively folded and stored in the storage box 101, and then the support bar 102 can be separated from the plug-in slot 103, and then the support bar 102 can be inserted into the gap between the inner wall of the storage box 101 and the muzzle bracket 2 and the butt bracket 3, so as to facilitate the personnel to carry, move or store, and at the same time reduce the probability of the support bar 102 being lost.

[0029] Both ends of the storage box 101 are provided with locking screw holes 106, and the locking screw holes 106 are internally threaded with positioning screws for tightening the muzzle bracket 2 or the butt bracket 3. The positioning screws cooperate with the locking screw holes 106 to position the inclination angles of the muzzle bracket 2 and the butt bracket 3, and then the inclination angles of the muzzle bracket 2 and the butt bracket 3 can be adjusted, so as to adapt to firearms of different gun lengths within a certain range to a certain extent. At the same time, in order to ensure the stability of the connection between the support bar 102 and the plug-in slot 103, a locking screw 105 for tightening the support bar 102 is assembled on the base 1.
