Description

Technical Field

[0001] This utility model relates to the field of shell loading technology, specifically to a shell casing fixing mechanism and a launching device. Background Technology

[0002] The cartridge case is the basic component of a bullet or artillery shell. It is made of metal and is mainly used to contain the propellant and connect the projectile to the primer to form a complete projectile.

[0003] For artillery shells, the existing method of securing them involves using custom threads at the firing tube muzzle. Specifically, when loading the shell, the retaining cap inside the breech must be unscrewed, the ammunition loaded, and then the retaining cap screwed back on to secure the shell. The same process must be repeated when disassembling the shell casing after firing.

[0004] This method has drawbacks such as being cumbersome to operate, inconvenient to use, and requiring a long preparation time. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing shell fixing method is threaded fixing. The purpose is to provide a shell casing fixing mechanism and a launching device to solve the above-mentioned problem.

[0006] This utility model is achieved through the following technical solution:

[0007] In a first aspect, this utility model provides a cartridge case fixing mechanism, comprising:

[0008] Equipped with a detachable shell launcher;

[0009] And, a clamping module for securing the projectile in the launch tube;

[0010] The shell casing is provided with a fixing groove, and the clamping module has a fixing end that is adapted to the fixing groove. The fixing end has a first position that is inserted into the fixing groove and a second position that is disengaged from the fixing groove. Accordingly, the clamping module is used to control the position of the fixing end.

[0011] In one possible design, the clamping module includes a sleeve, a clamping block, and an eccentric handle;

[0012] The sleeve is located at the end of the launching tube;

[0013] The clamping block includes an outwardly protruding insertion portion that extends into the launch tube, and correspondingly, the insertion portion is configured as the fixed end;

[0014] An eccentric handle passes through a sleeve and connects to a clamping block. Accordingly, the eccentric handle is used to drive the clamping block to reciprocate, and to control whether the insertion part is inserted into the launch tube and whether the insertion part is inserted into the fixed groove through the eccentric movement.

[0015] In one possible design, the eccentric handle includes a lever and a handle body;

[0016] The pull rod is inserted into the sleeve, with one end of the pull rod extending out of the sleeve and connecting to the handle body, and the other end of the pull rod extending out of the sleeve and connecting to the clamping block; an elastic element is placed inside the sleeve and fitted onto the pull rod.

[0017] The handle body is connected to the pull rod via an eccentric wheel;

[0018] The end of the sleeve is constructed as a first inclined surface, and the end of the launching tube is provided with a second inclined surface adapted to the first inclined surface. The first and second inclined surfaces form a fixed surface for the reciprocating motion of the insertion part.

[0019] Correspondingly, when the handle is turned, the eccentric wheel moves and pulls the lever and clamping block to move back and forth, so that the insertion part moves back and forth along the fixed surface.

[0020] In one possible design, the clamping block includes a base and a connector, the base being fitted onto the sleeve and connected to the pull rod, and the connector being connected to the base and extending into the launch tube.

[0021] In one possible design, the two ends of the sleeve are provided with a first gap at the connection point with the tie rod, and the base is provided with a second gap at the connection point with the tie rod.

[0022] In one possible design, a cushioning pad is provided between the sleeve and the handle body.

[0023] In one possible design, the cushioning pad comprises rubber pads and pad blocks stacked sequentially.

[0024] In one possible design, there are several clamping modules evenly distributed around the circumference of the launch tube; correspondingly, there are several fixing slots on the cartridge case, each corresponding to one of the clamping modules.

[0025] In one possible design, the fixing groove is constructed as an annular groove.

[0026] Secondly, this utility model provides a launching device, including the aforementioned cartridge case fixing mechanism.

[0027] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0028] By replacing the existing threaded connection with a clamping module, the need for repeated tightening and loosening of the threads is eliminated, reducing the cumbersome process of loading and unloading shells. This enables rapid loading of shells and rapid removal of shell casings, simplifying operation and making it convenient to use, thus effectively shortening combat readiness time.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0035] Example:

[0036] like Figure 1 and Figure 2 As shown, in a first aspect, the present invention provides a cartridge case fixing mechanism, comprising:

[0037] The launch tube 1 is equipped with a detachable shell 2;

[0038] And, a clamping module for securing the projectile 2 in the launch tube 1;

[0039] The shell 2 has a fixed groove 201 on its casing. The clamping module has a fixed end that is adapted to the fixed groove 201. The fixed end has a first position that is inserted into the fixed groove 201 and a second position that is removed from the fixed groove 201. Accordingly, the clamping module is used to control the position of the fixed end.

[0040] In the aforementioned shell casing fixing mechanism, the shell casing of the artillery shell 2 is fixed by the reciprocating movement of the clamping module. Specifically, when the fixing end moves to the first position, it is inserted into the fixing groove 201, allowing the clamping module to fix the shell casing of the artillery shell 2. When the fixing end moves to the second position, it disengages from the fixing groove 201, allowing the clamping module to disengage from the artillery shell 2. Thus, the operator can simply operate the clamping module, replacing the existing threaded connection and eliminating the need for repeated tightening and loosening of threads. This reduces the cumbersome process of loading and unloading the artillery shell 2, enabling rapid loading and unloading of the shell casing, simplifying operation, and facilitating use, effectively shortening combat readiness time.

[0041] During operation, first move the fixed end of the clamping module to the second position to avoid interfering with the loading of shell 2. After shell 2 is loaded into the launch tube 1, the operator operates the clamping module again to move the fixed end to the first position, thereby fixing shell 2 and restricting its axial freedom in the launch tube 1. After shell 2 is fired, the shell casing is removed, or, if necessary, the entire shell 2 needs to be removed; simply move the fixed end of the clamping module to the second position.

[0042] In one possible implementation, the clamping module includes a sleeve 3, a clamping block 4, and an eccentric handle 5;

[0043] Sleeve 3 is located at the end of launching tube 1;

[0044] The clamping block 4 includes an outwardly protruding insertion portion 42 that extends into the launching tube 1, and correspondingly, the insertion portion 42 is configured as the fixed end;

[0045] The eccentric handle 5 passes through the sleeve 3 and connects to the clamping block 4. Accordingly, the eccentric handle 5 is used to drive the clamping block 4 to reciprocate, and controls whether the plug-in part 42 is inserted into the launching tube 1 and whether the plug-in part 42 is inserted into the fixing groove 201 through the eccentric movement.

[0046] Based on the above design, eccentric motion is achieved through the eccentric handle 5. Compared to circular motion, during eccentric motion, the distance between the eccentric handle 5 and the center of rotation changes. The eccentric handle 5 uses this change in distance to drive the clamping block 4, thereby controlling the length of the insertion part 42 into the launching tube 1. In other words, when the insertion part 42 is inserted into the launching tube 1, the insertion part 42 can be inserted into the fixing groove 201; conversely, when the insertion part 42 is disengaged from the launching tube 1, the insertion part 42 also disengages from the fixing groove 201.

[0047] For the staff, the only operation required is to select the rotation direction of the eccentric handle 5 according to the operation situation. There is no need to tighten the threads, making the operation simpler and requiring less time, effectively realizing the rapid loading of the shell 2 and the rapid disassembly of the shell casing.

[0048] In one possible implementation, the eccentric handle 5 includes a lever 51 and a handle body 52;

[0049] A pull rod 51 is inserted into a sleeve 3. One end of the pull rod 51 extends out of the sleeve 3 and is connected to the handle body 52. ​​The other end of the pull rod 51 extends out of the sleeve 3 and is connected to the clamping block 4. An elastic element 6 is placed inside the sleeve 3 and sleeved on the pull rod 51.

[0050] The handle body 52 is connected to the pull rod 51 via the eccentric wheel 53;

[0051] The end of the sleeve 3 is constructed as a first inclined surface, and the end of the launching tube 1 is provided with a second inclined surface adapted to the first inclined surface. The first inclined surface and the second inclined surface form a fixed surface 7 for the reciprocating motion of the insertion part 42.

[0052] Correspondingly, when the handle is turned, the eccentric wheel 53 moves and pulls the lever 51 and the clamping block 4 to move back and forth, so that the insertion part 42 moves back and forth along the fixed surface 7.

[0053] Based on the above design, when the operator rotates the handle body 52, since the handle body 52 is connected to the pull rod 51 through the eccentric wheel 53, the handle body 52 causes the pull rod 51 to move back and forth through eccentric movement. If the distance between the handle body 52 and the rotation center is shortened, the pull rod 51 is driven to move towards the handle body 52, and the elastic element 6 deforms accordingly. Conversely, if the distance between the handle body 52 and the rotation center is increased, the pull rod 51 is reset under the combined action of the push of the handle body 52 and the elastic force of the elastic element 6.

[0054] For clamping block 4, when pull rod 51 moves back and forth, insertion part 42 slides back and forth along fixed surface 7, causing the movement direction of insertion part 42 to tilt, thereby driving insertion part 42 to move radially along launch tube 1, thereby controlling whether insertion part 42 is inserted into launch tube 1.

[0055] In this regard, the movement direction of the pull rod 51 intersects with the movement direction of the insertion part 42. To prevent their movements from conflicting, preferably, a first gap 81 is provided at the connection points between the two ends of the sleeve 3 and the pull rod 51, and a second gap 82 is provided at the connection point between the base 41 and the pull rod 51. Based on this, the flexibility of the component movement is increased by setting the gaps, thereby coordinating the respective movements of the pull rod 51 and the insertion part 42.

[0056] It is easy to understand that any suitable existing spring can be selected for the elastic element 6, which has a wide range of choices and good practicality.

[0057] In one possible implementation, the clamping block 4 includes a base 41 and a connector 42. The base 41 is located outside the sleeve 3 and connected to the pull rod 51. The connector 42 is connected to the base 41 and extends into the launch tube 1. Based on this, the base 41 is used to connect the pull rod 51, and the connector 42 is located between the base 41 and the launch tube 1, effectively protecting the connector 42 and extending its service life. It is readily understood that the base 41 and the connector 42 can be constructed in any suitable shape to adapt to different usage environments.

[0058] In one possible implementation, a buffer pad 9 is provided between the sleeve 3 and the handle body 52. ​​Based on this, the buffer pad 9 reduces wear and improves the service life of the sleeve 3, the eccentric wheel 53 and surrounding parts. The buffer pad 9 also plays a positioning and fixing role, ensuring the accurate position of the eccentric handle 5.

[0059] Optionally, the cushioning pad 9 includes rubber pads 91 and pad blocks 92 stacked sequentially. It is readily understood that the rubber pads 91 and pad blocks 92 can each be made of any suitable material.

[0060] In one possible implementation, several clamping modules are provided and evenly distributed around the circumference of the launch tube 1; correspondingly, several fixing slots 201 on the shell casing are provided and are set one-to-one with the clamping modules. Based on the above design scheme, multi-point fixing and positioning are achieved by increasing the number of clamping modules, thereby improving the fixing effect of the shell 2.

[0061] In one possible implementation, the fixing groove 201 is constructed as an annular groove. Based on this, when loading the projectile 2, there is no need to pay attention to aligning the clamping module with the fixing groove 201. When the projectile 2 reaches the designed position, the fixing end of the clamping module can be inserted into any suitable position in the annular groove, making it more convenient to use.

[0062] Secondly, this utility model provides a launching device, including the aforementioned cartridge case fixing mechanism. Based on this, the launching device can also include other suitable functional modules in addition to the cartridge case fixing mechanism, thus enriching its functionality to meet different operational requirements and improving its practicality. Furthermore, it is readily understood that any suitable existing equipment can be selected for these functional modules, offering a wide range of choices.

[0063] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
