[0030] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0031] Example 1

[0032] This embodiment 1 provides a locking device for an ammunition housing 1, such as Figure 1 and Figure 2 As shown, the outer wall of the ammunition housing 1 is provided with an annular groove 11, and further comprises:

[0033] A launching tube 2, wherein the launching tube 2 is slidably sleeved on the outer wall of the ammunition housing 1;

[0034] The locking member is connected to the launch tube 2 and is abutted against or separated from the annular groove 11 by a driving assembly, so as to realize locking or unlocking of the launch tube 2 and the ammunition shell.

[0035] In the prior art, the ammunition is fixed by two custom threads of the launch tube. When loading the ammunition, the fixing cover needs to be screwed off, and after loading the ammunition, the fixing cover is screwed back to secure the ammunition. The same operation needs to be performed when disassembling the shell.

[0036] The above method realizes the tightening and loosening of ammunition in a detachable form, but the threaded fixing method requires the operator to perform repeated rotation operations, and there are also problems such as taking a long time, being inconvenient to use, and having a long combat readiness time.

[0037] In order to solve the above-mentioned problem, a locking piece is provided in the present embodiment. Similar to the original threaded fixing method, the present embodiment also realizes the detachable form of the ammunition casing 1 and the launching tube 2 through the locking piece. The difference is that the staff drives the locking piece to work through the driving assembly, so as to quickly unlock or lock the launching tube 2 and the ammunition casing 1, thereby improving the equipment efficiency of the staff and being simple and quick to use.

[0038] Specifically, the specific working process of this embodiment is:

[0039] The ammunition casing 1 is slidably sleeved in the launching tube 2 , and the launching tube 2 and the ammunition casing 1 are locked and fixed by the locking piece abutting against the annular groove 11 .

[0040] When locking, the driving assembly is started to work, and the driving assembly drives the locking member to enter the annular groove 11, so that the ammunition housing 1 cannot move to complete the locking.

[0041] When unlocking, the driving assembly is started again, and the driving assembly drives the locking member away from the annular groove 11. At this time, the ammunition housing 1 can be pulled out of the launch tube 2 to achieve unlocking.

[0042] Further optimization, such as Figure 2 As shown, the locking member includes two symmetrically arranged protrusions 3; when locked, the two protrusions 3 are matched and offset with the annular groove 11. The locking method of this embodiment is: through the two protrusions 3 and the annular groove 11, it should be understood that the number of protrusions 3 is not limited and the number can also be one, three or four, etc., which can be set according to actual conditions. Considering the operating speed of the staff and the stability of the locking, the two symmetrical protrusions 3 and the annular groove 11 are set in this embodiment, which is sufficient to ensure the stable locking of the locking member and the subsequent operating efficiency of the staff.

[0043] Further optimized, the launch tube 2 includes a drive sleeve 21, the drive sleeve 21 is provided with two symmetrically arranged drive holes 211, and the drive assembly includes two drive parts 4 respectively connected to the two protrusions 3, and the two drive parts 4 are respectively slidably connected to the two drive holes 211.

[0044] The two driving holes 211 in this embodiment correspond to the positions of the driving parts 4, providing conditions for the operation of the driving parts 4. It should be understood that the number of driving parts 4 corresponds to the number of protrusions 3, that is, each driving part 4 can drive a corresponding protrusion 3 to complete the locking or unlocking work. If the number of protrusions 3 is three or four, the number of driving parts 4 can be three or four.

[0045] Further optimization, such as Figure 2 and Figure 3 As shown, the driving sleeve 21 is arranged obliquely close to one side of the ammunition housing 1, and the two driving parts 4 each include:

[0046] A pull rod 41, wherein the pull rod 41 is slidably arranged in the driving hole 211 and a wedge block 42 is connected to the top of the pull rod 41 and is wedge-matched with the inclined side of the driving sleeve 21, and the wedge block 42 is connected to the protrusion 3 on the side close to the ammunition housing 1;

[0047] A spring 43, wherein the spring 43 is disposed in the driving hole 211 and the spring 43 is sleeved on the pull rod 41;

[0048] The cam portion 44 is rotationally connected to the bottom of the pull rod 41 via a rotating shaft. The purpose of the rotational connection here is to always ensure that the pull rod 41 is in a vertical state. The rotation of the cam portion 44 will still drive the pull rod 41 to move in the vertical direction and the horizontal direction.

[0049] Specifically, the working process of the driving unit 4 in this embodiment is as follows:

[0050] When unlocking, the staff drives the cam portion 44 to rotate. Since the pull rod 41 is connected to the cam portion 44 in rotation, the cam 442 will drive the pull rod 41 to move obliquely upward, that is, move away from the launching tube 2. At the same time, the pull rod 41 drives the wedge block 42 to move obliquely upward and always cooperates with the inclined wedge of the driving sleeve 21; it guides the movement of the pull rod 41. At this time, the spring 43 is compressed upward, but since there is a large friction between the cam portion 44 and the rotating shaft, and the friction is greater than the elastic force of the spring 43, the cam portion 44 will not automatically reset after rotation, and finally the wedge block 42 drives the protrusion 3 to leave the annular groove 11 to achieve unlocking.

[0051] When locking, the staff drives the cam 442 to rotate in the opposite direction. Since the pull rod 41 is connected to the cam portion 44 for rotation, the cam 442 will drive the pull rod 41 to move obliquely downward, that is, move in the direction close to the launching tube 2. At the same time, the pull rod 41 drives the wedge block 42 to move obliquely downward and always cooperates with the inclined wedge shape of the driving sleeve 21; it guides the movement of the pull rod 41. At this time, the spring 43 is compressed downward, but since there is a large friction between the cam portion 44 and the rotating shaft, and the friction is greater than the elastic force of the spring 43, the cam portion 44 will not automatically reset after rotation, and finally the wedge block 42 drives the protrusion 3 to enter the annular groove 11 for locking.

[0052] Further optimized, the cam portion 44 includes a cam 442 and a driving handle 441 , and the driving handle 441 is disposed on the outer periphery of the cam 442 and is integrally connected to the cam 442 .

[0053] In this embodiment, the driving handle 441 is convenient for the staff to rotate, wherein, Figure 1 As shown, the two driving handles 441 are symmetrically arranged relative to the launch tube 2. To facilitate the staff to operate the driving handles 441, the two driving handles 441 are configured to be bent outwards in an arc shape. The cam 442 provides conditions for the movement of the pull rod 41.

[0054] Further optimized, a cushion block 6 and a buffer pad 5 are connected between the cam 442 and the driving sleeve 21 , the cushion block 6 abuts against the cam 442 , and the buffer pad 5 abuts against the bottom of the driving sleeve 21 .

[0055] The function of the cushion block 6 is to contact the cam 442. The cam 442 and the cushion block 6 contact and resist each other, which can increase the contact area between the cam 442 and the cushion block 6, thereby increasing the friction force, thereby further avoiding the autonomous sliding of the cam 442. In order to ensure the contact and cooperation between the cushion block 6 and the cam 442, the bottom of the cushion block 6 is concave to adapt to the shape of the cam 442, so as to avoid the cam 442 from resisting the cushion block 6 too much and causing damage.

[0056] In addition, in order to avoid damage to the cushion block 6 , a buffer pad 5 is provided between the cushion block 6 and the driving sleeve 21 . The buffer pad 5 has good elasticity and can avoid hard contact between the cushion block 6 and the cam 442 .

[0057] Further optimization, in order to ensure the elastic characteristics of the buffer pad 5, it is set that the buffer pad 5 is made of rubber material.

[0058] Further optimization, in order to increase the contact area between the wedge block 42 and the ammunition case 1, an arc groove is provided on the side of the wedge block 42 that abuts against the ammunition case 1. When locked, the protrusion 3 is located in the annular groove 11, and at this time, one side of the wedge block 42 also abuts against the ammunition case 1. In order to better allow the protrusion 3 to enter the annular groove 11, the contact surface of the wedge block 42 is provided with an arc groove to better adapt to the ammunition case 1.

[0059] The specific working process of the utility model is:

[0060] The ammunition casing 1 is slidably mounted in the launch tube 2.

[0061] When unlocking, the staff grasps the driving handle 441 and rotates it outward. Since the pull rod 41 is connected to the cam portion 44 for rotation, the cam 442 will drive the pull rod 41 to move obliquely upward, that is, move away from the launching tube 2. At the same time, the pull rod 41 drives the wedge block 42 to move obliquely upward and always cooperates with the inclined wedge of the driving sleeve 21; it guides the movement of the pull rod 41. At this time, the spring 43 is compressed upward, but since there is a large friction between the cam portion 44 and the rotating shaft, and the friction is greater than the elastic force of the spring 43, the cam portion 44 will not automatically reset after rotation, and finally the wedge block 42 drives the protrusion 3 to leave the annular groove 11 to achieve unlocking.

[0062] When locking, the staff grasps the driving handle 441 and rotates it inward. Since the pull rod 41 is connected to the cam portion 44 for rotation, the cam 442 will drive the pull rod 41 to move obliquely downward, that is, move in the direction close to the launching tube 2. At the same time, the pull rod 41 drives the wedge block 42 to move obliquely downward and always cooperates with the inclined wedge shape of the driving sleeve 21; it guides the movement of the pull rod 41. At this time, the spring 43 is compressed downward, but since there is a large friction between the cam portion 44 and the rotating shaft, and the friction is greater than the elastic force of the spring 43, the cam portion 44 will not automatically reset after rotation, and finally the wedge block 42 drives the protrusion 3 to enter the annular groove 11 for locking.

[0063] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
