[0038] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0039] Please see Figures 1 to 11 The folding target plate 100 includes multiple sets of target plate assemblies 1 and multiple sets of locking assemblies. The multiple sets of target plate assemblies 1 are detachably connected in sequence along a first direction, and each set of target plate assemblies 1 includes multiple target plates 11. The multiple target plates 11 in the same set are connected in sequence along a second direction, and two adjacent target plates 11 in the same set can rotate relative to each other about an axis located in the first direction, wherein the first direction intersects the second direction. The multiple sets of locking assemblies correspond to the multiple sets of target plate assemblies 1, and each set of locking assemblies includes multiple locking parts 2. The locking parts 2 are detachably connected between two adjacent target plates 11 in the same set to restrict the relative rotation of the two adjacent target plates 11 in the same set.

[0040] In the folding target plate 100 provided by the present invention, since multiple sets of target plate assemblies 1 are detachably connected in sequence, the number of target plate assemblies 1 can be selected according to the caliber of the artillery to adjust the size of the target composed of multiple target plate assemblies 1 in the first direction, so as to meet the simultaneous correction of multiple optical axes; at the same time, the locking part 2 can be disassembled and installed so that two adjacent target plates 11 in the same group can rotate relative to each other, so that the two adjacent target plates 11 have two states of open and folded, so as to adjust the size of the target in the second direction and improve practicality; and when transporting the target, multiple sets of target assemblies can be disassembled, and the locking part 2 on each set of target assemblies can be removed from the corresponding target plate 11, so that two adjacent target plates 11 in the same group can be rotated to the folded position, reducing the space occupied by the folding target plate 100 and facilitating transportation.

[0041] It should be noted that in this scheme, two adjacent target plates 11 in the same group are rotatably connected by a hinge 12, and the axis of the hinge 12 coincides with the first direction. Specifically, in this embodiment, the first direction is the length direction of the folded target plate 100, and the second direction is the height direction of the folded target plate 100; and in the example drawings, the first direction and the second direction are shown as F1 and F2, respectively.

[0042] Furthermore, each target plate 11 has a connecting groove 11a at both ends in the first direction, with the end of the connecting groove 11a near the adjacent target plate assembly 1 open; the folded target plate 100 also includes multiple connecting strips 3, which correspond to multiple sets of target plate assemblies 1, and both ends of each connecting strip 3 are inserted into two connecting grooves 11a of two adjacent sets, so that the target plate assemblies 1 of two adjacent sets can be detachably connected. In this embodiment, by inserting the connecting strips 3 into two connecting grooves 11a of two adjacent sets, the target plate assemblies 1 of two adjacent sets can be detachably connected, which is simple in structure, cost-effective, and easy to operate. It should be noted that in this embodiment, the target plate 11 consists of a plate body and a frame body, with the plate body fixed to the frame body by screws, and the connecting grooves 11a are opened on the corresponding frame body.

[0043] Furthermore, each connecting groove 11a has an opening on its side intersecting with its opening to form a clearance opening 11b, the size of which is smaller than the size of the boss of the connecting strip 3; each connecting strip 3 is provided with a connecting screw hole 3a, and the folding target plate 100 also includes multiple connecting bolts 4, one end of each connecting bolt 4 being screwed into the connecting screw hole 3a and able to press against the inner wall opposite to the connecting groove 11a and the clearance opening 11b to restrict the movement of the connecting strip 3. In this solution, the connecting strip 3 and two target plates 11 in two adjacent groups are fixed together by the connecting bolts 4, improving the connection stability of the two adjacent target plate assemblies 1; when it is necessary to disassemble the target plate assembly 1, it is only necessary to loosen the connecting bolts 4 and remove the connecting strip 3.

[0044] Similarly, in this embodiment, each target plate 11 has locking grooves 11d at both ends in the second direction, with one end of the locking groove 11d open near the target plate 11 in the same group; the locking part 2 is a locking strip 21, with both ends of the locking strip 21 inserted into two adjacent locking grooves 11d in the same group, to restrict the relative rotation of two adjacent target plates 11 in the same group. That is, by inserting the locking strip 21 into the locking grooves 11d of two adjacent target plates 11 in the same group, the relative rotation of two adjacent target plates 11 in the same group is restricted.

[0045] Furthermore, each locking groove 11d has an opening on its side intersecting with its open portion to form a connecting opening 11e, the size of which is smaller than the size of the boss on the locking strip 21. Each locking strip 21 is provided with a locking screw hole, and each locking assembly also includes a locking bolt 5. One end of the locking bolt 5 is screwed into the locking screw hole and can press against the inner wall opposite to the locking groove 11d and the connecting opening 11e to restrict the movement of the locking strip 21. In this embodiment, the locking strip 21 and two adjacent target plates 11 in the same group are fixed together by the locking bolt 5 to improve the connection stability of the two adjacent target plates 11 in the same group when they are in the open position. Similarly, when it is necessary to fold the two adjacent target plates 11 in the same group, it is only necessary to loosen the locking bolt 5 and remove the locking strip 21.

[0046] Furthermore, each locking assembly also includes multiple rotating handles 51, each corresponding to a multiple locking bolt 5. Each rotating handle 51 is connected to its corresponding locking bolt 5 and can rotate radially around the locking bolt 5. In this design, the operator can rotate the locking bolt 5 by holding the rotating handle 51, improving convenience. At the same time, since the rotating handle 51 can rotate radially relative to the locking bolt 5, it can be rotated and folded away when not in use, reducing its space occupation.

[0047] Furthermore, the folding target plate 100 also includes a support arm 6 and a fixing structure. One end of the support arm 6 is connected to the target plate assembly 1, and the other end is provided with a fixing structure for fixing to the ground. In this embodiment, the support arm 6 is fixed to the ground by the fixing structure, so that the target plate assembly 1 located at the other end of the support arm 6 can be spaced from the ground, which facilitates artillery aiming.

[0048] Furthermore, the fixing structure includes a fixing base 7 and multiple fixing bolts. The fixing base 7 is connected to the end of the support arm 6 away from the target plate assembly 1, and multiple fixing holes 7a are provided corresponding to the multiple fixing bolts. One end of each fixing bolt is used to pass through the corresponding fixing hole 7a and be inserted into the ground. In this solution, the folding target plate 100 is fixed to the platform ground or hard surface by fixing bolts passing through the fixing holes 7a of the fixing base 7 and being inserted into the ground.

[0049] To improve the stability of the folding target plate 100 during operation, in this embodiment, multiple support arms 6 are provided, spaced apart along a first direction, and correspondingly, multiple fixing structures are provided. Specifically, the fixing base 7 has a mounting screw hole 7b on the side away from the support arm 6, and the fixing structure also includes a plug screw 8. One end of the plug screw 8 has a mounting screw rod 81, and the other end is tapered. The mounting screw rod 81 is screwed into the mounting screw hole 7b. Thus, when it is necessary to fix uneven or sandy ground, the mounting screw rod 81 can be screwed into the mounting screw hole 7b of the fixing base 7, and the tapered end of the plug screw 8 can be inserted into the uneven ground or sand to maintain its stability.

[0050] Specifically, the end of the support arm 6 furthest from the target plate assembly 1 is provided with multiple extension arms 61. These extension arms 61 are spaced apart at their ends furthest from the support arm 6. Multiple sets of fixing structures are provided, each corresponding to one of the extension arms 61, and each fixing base 7 is connected to its corresponding extension arm 61. That is, the multiple extension arms 61 furthest from the target plate assembly 1 increase the support points between the support arm 6 and the ground, improving the installation stability of the folded target plate 100. Furthermore, in this embodiment, the support arm 6 can be composed of multiple segments, each segment having a splicing groove into which a splicing strip 9 is inserted, and the support arm 6 and the corresponding splicing strip 9 are connected by screws.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
