Specific embodiments

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Refer to Figure 1-7 , a target paper replacement device for shooting training, including two spaced-apart bases 1 and universal wheels 17 provided on the bases 1. Here, the universal wheels 17 can facilitate movement and also play a supporting role. Among them, the universal wheels 17 are structures with built-in brake components in the prior art. The bases 1 have a certain weight. In order to facilitate movement, universal wheels commonly used in the prior art can also be provided under the bases. On both bases 1, there are vertically upwardly provided mounting cylinders 2. Reinforcing rods are provided between both sides of the mounting cylinders 2 and the bases 1 to ensure the stability of the mounting cylinders 2. At the lower parts of both mounting cylinders 2, there are first electric telescopic rods, and at the upper parts, there are slidably provided support columns 3. And the bottom ends of the support columns 3 are connected to the top ends of the output ends of the first electric telescopic rods. On the upper parts of both support columns 3, there are horizontally provided cross bars 4. Reinforcing ribs are provided between the included angles of the cross bars 4 and the support columns 3. Vertically downwardly provided connection blocks 5 are provided at the ends of both cross bars 4. First clamping mechanisms 6 are provided on both connection blocks 5. Horizontally provided between the two mounting cylinders 2 directly below the two first clamping mechanisms 6 is a cylinder 7. The cylinder 7 is composed of two semi-cylinders hinged together. At the lower parts of both mounting cylinders 2, there are horizontally provided mounting plates. The cylinder 7 is horizontally arranged between the two mounting plates. One of the semi-cylinders is detachably connected to the mounting plate by bolts. The two semi-cylinders are rotatably connected by hinges on one side and locked by a locking structure on the other side. Among them, the locking structure is a commonly used locking structure in the prior art. Rotating shafts 8 are provided at both ends of the cylinder 7. Removable paper roller mounting snap rings 11 are provided on the opposite sides of the two rotating shafts 8. The paper roller mounting snap rings 11 are composed of two semi-circular snap rings. One of the snap rings is fixedly connected to the rotating shaft 8, and the other snap ring is connected to it by bolts. One of the semi-cylinders is provided with a through slot 9 along its length direction for the target paper to pass through. The through slot 9 is vertically located between the connection block 5 and the first clamping mechanism 6. A paper cutting mechanism 10 is provided on one side of the cylinder 7. The first electric telescopic rod, the first clamping mechanism 6, and the paper cutting mechanism 10 are all connected to the controller.

[0030] A connecting column is horizontally arranged between the tops of the two support columns 3. A spool mounting seat 18 is slidably arranged on both the connecting column and a support column 3. A spool is arranged on the spool mounting seat 18. After the first shot, with the bullet hole as the center of the circle, the coordinate axes are drawn using the spool, which improves efficiency, saves time, and avoids errors caused by drawing the coordinate axes by hand.

[0031] A guiding block 12 is inclined on one side of the through groove 9, which is convenient for the rotating shaft 8 to drive the target paper to output better outside the cylinder 7 when rotating.

[0032] Both of the two connecting blocks 5 are of hollow structure. A sliding rod 13 is slidably arranged in each of the two connecting blocks 5. A second electric telescopic rod 14 is arranged on each of the two connecting blocks 5. The output ends of the two second electric telescopic rods 14 are respectively connected to the corresponding sliding rods 13 through connecting blocks. A second clamping mechanism 15 is arranged on each of the two sliding rods 13. The setting of the second clamping mechanism 15 is convenient for better clamping and fixing the target paper, and thus can avoid the target paper shaking during shooting. The second electric telescopic rod 14 and the second clamping mechanism 15 are both connected to the controller. The vertical distance between the through groove 9 on the cylinder 7 and the ground is greater than the distance between the top end of the connecting block 5 and the bottom end of the sliding rod 13. When in use, after the first clamping mechanism 6 clamps the target paper and the support column 3 rises to the set position, the second electric telescopic rod 14 is started, which drives the sliding rod 13 to displace downward. When the second clamping mechanism 15 displaces to the end of the target paper, it can clamp both sides of the target paper on the sliding rod 13.

[0033] The first clamping mechanism 6 and the second clamping mechanism 1 both include two sliding grooves 601, an inverted L-shaped clamping block 602, and a third electric telescopic rod 603. The two sliding grooves 601 are respectively arranged on one side of the connecting block 5 and one side of the sliding rod 13, and the sliding grooves 601 on both sides are arranged away from each other. An inverted L-shaped clamping block 602 is slidably arranged in each of the two sliding grooves 601, and the horizontal parts of the two inverted L-shaped clamping blocks 602 face the connecting block 5 and the sliding rod 13 respectively. A third electric telescopic rod 603 is arranged on one side of the connecting block 5 and the sliding rod 13 away from the horizontal part of the inverted L-shaped clamping block 602. The third electric telescopic rod 603 is arranged on the side away from the shooting direction to avoid being damaged during shooting. The output ends of the two third electric telescopic rods 603 are respectively connected to the vertical parts of the two inverted L-shaped clamping blocks 602 through connecting pieces. The third electric telescopic rod 603 is connected to the controller. When clamping the target paper, when the target paper is located between the connecting block 5 and the inverted L-shaped clamping block 602, the controller controls the third electric telescopic rod 603, and the third electric telescopic rod 603 drives the horizontal part of the inverted L-shaped clamping block 602 to gradually displace towards the connecting block 5. When the target paper is clamped, the third electric telescopic rod 603 is stopped.

[0034] Anti-slip teeth 604 are arranged on the inner side of the horizontal part of the inverted L-shaped clamping block 602. The setting of the anti-slip teeth 604 is convenient for better clamping the target paper on the connecting block 5.

[0035] First limit blocks 605 are provided on both the upper and lower sides of the inverted L-shaped clamping block 602. First limit grooves adapted for the sliding of the first limit blocks 605 are formed on the upper and lower side walls of the sliding groove 601. The arrangement of the first limit blocks 605 and the first limit grooves can ensure the stability of the inverted L-shaped clamping block 602 during displacement.

[0036] The paper cutting mechanism 10 includes a lead screw module 101 which is connected to a support. The distance between the lead screw module 101 and the cylinder 7 is adapted for the first clamping mechanism 6 and the second clamping mechanism 15 to move up and down through. A paper cutter mounting seat 102 is horizontally provided on the top surface of the sliding seat of the lead screw module 101. A paper cutter 103 is detachably connected to the paper cutter mounting seat 102. The initial position of the paper cutter 103 is on one side of the target paper. The paper cutter 103 is located on one side of the target paper. The lead screw module 101 is driven by a lead screw motor 104 which is connected to the controller. During paper cutting, the controller controls the lead screw motor 104 to rotate, which drives the lead screw to rotate and can drive the sliding seat to displace on the lead screw. During the displacement of the sliding seat, the paper cutter 103 can cut the target paper.

[0037] Second limit grooves are vertically formed on the opposite inner sides of the two mounting cylinders 2. Second limit blocks 16 which can slide in the second limit grooves are vertically provided on both sides of the support column 3, which can ensure the stability of the support column 3 during up and down displacement.

[0038] Preferably, the base 1, the mounting cylinders 2, the support columns 3, the cross bars 4, the connecting blocks 5, the sliding rods 13, the cylinder 7 and the inverted L-shaped clamping block 602 are all made of aluminum alloy material. While the aluminum alloy material has a certain strength, if a bullet hits each component, the risk of ricochet can also be reduced and the safety can be improved.
