Description

Technical Field

[0001] This invention relates to the field of mechanical structure design, and in particular to a novel gun mount for mortars. Background Technology

[0002] Mortars are used for close-range suppression of the enemy and to kill concealed targets behind bunkers. They are suitable for environments such as high-altitude mountains, hilly areas, and urban alleyways. The mortar carriage is an important component of the mortar, mainly used to support the gun barrel and, in conjunction with the aiming device, to adjust the firing angle and direction. However, the mortar carriages currently in use have the disadvantage of slow setup and dismantling speed, which seriously restricts the efficiency of the mortar in transitioning between peacetime and combat states. Summary of the Invention

[0003] The purpose of this invention is to provide a new type of mortar mount that enables rapid mortar mounting and adjustment during marches and missions, meeting the requirements of easy portability, high reliability, high serviceability, and rapid aiming operation.

[0004] This invention provides a novel mortar carriage, comprising an elevation mechanism, a left support leg, and a right support leg, consisting of an elevation outer cylinder and a lifting rod slidably connected inside the elevation outer cylinder. The outer wall of the elevation outer cylinder is fixed with a first connecting seat and a second connecting seat arranged vertically. The top of the right support leg is hinged to the first connecting seat, the middle position of the left support leg is hinged to the second connecting seat, and the top of the left support leg is hinged to a locking hoop fitted onto the outer wall of the right support leg. The elevation outer cylinder and the lifting rod are connected via a quick-adjustment self-locking mechanism, and the top of the lifting rod is connected to a mortar body fixing mechanism via a fine-adjustment mechanism.

[0005] Furthermore, the fine-tuning mechanism includes a threaded screw and a screw cylinder. The screw is fixedly connected to the top end of the lifting rod and is coaxially arranged. A directional joint that is rotatably connected to the screw cylinder is sleeved on the top outer wall of the screw cylinder. The top surface of the directional joint is slidably connected to the top surface of the screw cylinder.

[0006] Furthermore, a top head is fixedly installed on the top of the screw cylinder, penetrating the directional connector and extending above the directional connector. A detachably connected top cap is sleeved on the outer wall of the top head, and the bottom surface of the top cap is slidably connected to the top surface of the directional connector.

[0007] Furthermore, the gun barrel fixing mechanism is installed on the directional joint. The gun barrel fixing mechanism includes a directional mechanism, a bracket, and a gun rim. The directional mechanism is installed on the directional joint, the bracket is connected to the directional mechanism, and the gun rim is detachably connected to the bracket.

[0008] Furthermore, a scope holder is installed on the bracket, and the gun rim and the bracket are connected by a locking device.

[0009] Furthermore, a pressure cap is installed on the top surface of the high and low outer cylinders, and the lifting rod passes through the pressure cap.

[0010] Furthermore, the quick-adjustment self-locking mechanism includes a self-locking body disposed between the high and low outer cylinder and the lifting rod. A compression spring is installed between the top surface of the self-locking body and the pressure cover. The inner sidewall of the high and low outer cylinder is inclined near the lower half of the self-locking body. The lower half of the self-locking body has multiple placement holes. A self-locking pin is movably installed in the placement holes. The inner end of the self-locking pin is slidably connected to the lifting rod. The outer end of the self-locking pin is provided with an inclined end face that cooperates with the inclined surface.

[0011] Furthermore, an elongated groove is provided on the outer cylinder near the self-locking body, and a release handle is installed on the self-locking body that extends through the elongated groove to the outside of the high-low mechanism.

[0012] Furthermore, the placement holes are evenly distributed circumferentially, and there are two long slots, which are symmetrically arranged.

[0013] Furthermore, the bottom of the left and right support legs are respectively equipped with rotatably connected claws.

[0014] This invention features an optimized structure, with a triangular structure composed of the left and right outriggers and the elevation mechanism, ensuring stable force distribution. The triangular structure's two-point hinge and one-point sliding lock characteristics improve the efficiency of mortar mount erection and dismantling. It also allows for rapid adjustment of the mortar's firing angle and direction, meeting requirements for portability, high reliability, high serviceability, and rapid aiming operation.

[0024] Example 1

[0025] like Figures 1-3 As shown:

[0026] A novel mortar mount includes an elevation mechanism 1, a right support leg 2, and a left support leg 3. The outer wall of the elevation outer cylinder 11 is fixed with a first connecting seat 13 and a second connecting seat 14 arranged vertically. The top of the right support leg 2 is hinged to the first connecting seat 13. A limiting screw 15 is installed at the hinge between the first connecting seat 13 and the right support leg 2. The right support leg 2 rotates about the central axis of the limiting screw 15. The middle position of the left support leg 3 is hinged to the second connecting seat 14. A limiting screw 15 is also installed at the hinge between the second connecting seat 14 and the left support leg 3. The left support leg 3 rotates about the central axis of the limiting screw 15.

[0027] A locking hoop 32 is fitted onto the outer wall of the right outrigger 2, and the top of the left outrigger 3 is hinged to the locking hoop 32 via a connecting shaft 33.

[0028] like Figure 1 As shown, the high-low machine 1, right support leg 2 and left support leg 3 adopt an interconnected triangular structure layout. The top of the right support leg 2 and the middle position of the left support leg 3 are fixed relative to the high-low machine 1, but they can rotate. The top of the left support leg 3 can slide on the right support leg 2 by loosening the locking clamp 32.

[0029] The triangular structure composed of the elevation mechanism 1, right outrigger 2, and left outrigger 3 breaks with the traditional model and adopts an asymmetrical gun carriage structure layout. The simplified horizontal adjustment mechanism is merged and its function is incorporated into the overall gun carriage structure, which greatly simplifies the overall structure while ensuring the functionality and stability of the gun carriage.

[0030] When retracting, release the locking clamp 32, and the left outrigger 3 slides onto the right outrigger 2. The locking clamp 32 then moves the top of the left outrigger 3 to a position close to the bottom of the right outrigger 2. The right outrigger 2 then moves towards the elevation mechanism 1 to complete the retrieval of the gun mount. When in use, the locking clamp 32 moves the top of the left outrigger 3 to a position close to the middle of the right outrigger 2, while the right outrigger 2 extends away from the elevation mechanism 1 to complete the gun mount support. The dual-outrigger linkage design allows for retraction and synchronous locking in a single operation, making the action convenient and reliable.

[0031] The triangular structure utilizes structural stress self-locking to achieve structural stability of the gun carriage, and the gun carriage retraction and fixing method is optimized, which greatly improves the flexibility and serviceability of the gun carriage retraction.

[0032] The bottom of the left support leg 3 and the right support leg 2 are respectively equipped with a rotating left foot claw 31 and a right foot claw 21, which adopt two-point positioning and reliably realize the limitation of the left and right swing and the front and back swing of the elevation mechanism 1, thus solving the structural problem of large front and back swing of the traditional gun mount elevation mechanism 1.

[0033] The two legs are not coplanar with the elevation mechanism 1. When folded up, the legs and the elevation mechanism 1 do not interfere with each other, making them convenient to carry and operate.

[0034] like Figure 2 and Figure 3 As shown, the elevation mechanism 1 consists of an elevation outer cylinder 11 and a lifting rod 7 that is slidably connected inside the elevation outer cylinder 11. A pressure cover 12 is installed on the top surface of the elevation outer cylinder 11, and the lifting rod 7 passes through the pressure cover 12. The elevation outer cylinder 11 and the lifting rod 7 are connected by a quick-adjustment self-locking mechanism. The top of the lifting rod 7 is connected to a gun body fixing mechanism through a fine-adjustment mechanism.

[0035] The quick-adjustment self-locking mechanism includes a self-locking body 71 disposed between the high and low outer cylinder 11 and the lifting rod 7. The self-locking body 71 is sleeved on the outer wall of the lifting rod 7. A compression spring 73 is installed between the top surface of the self-locking body 71 and the pressure cover 12. The inner side wall of the high and low outer cylinder 11 is inclined near the lower half of the self-locking body 71. The lower half of the self-locking body 71 has multiple circumferentially distributed placement holes. A self-locking pin 72 is movably installed in the placement holes. The inner end of the self-locking pin 72 is slidably connected to the lifting rod 7. The outer end of the self-locking pin 72 is provided with an inclined end face that cooperates with the inclined surface.

[0036] The compression spring 73 prevents the self-locking body 71 from moving too high, while providing an initial force for the self-locking body 71 to move downward in its free state.

[0037] In this device, the friction between the self-locking body 71 and the lifting rod 7 is relatively large. Anti-slip treatment can be applied to the inner side of the self-locking body 71 or the outer wall of the lifting rod 7 near the self-locking body 71.

[0038] In addition to anti-slip treatment, the inner side of the self-locking body 71 near the lifting rod 7 can be made into a downward and inward side, and the outer wall of the lifting rod 7 near the self-locking body 71 can be provided with an external protrusion that cooperates with the inner side of the self-locking body 71.

[0039] The fine-tuning mechanism includes a screw 81 and a screw barrel 82 connected by threads. The outer wall of the screw 81 is externally threaded, and the inner wall of the screw barrel 82 is internally threaded to mate with the external threads. The screw 81 is fixedly connected to the top of the lifting rod 7 and is coaxially arranged. A directional connector 4 is sleeved on the top outer wall of the screw barrel 82 and is rotatably connected to the screw barrel 82. The top surface of the directional connector 4 is slidably connected to the top surface of the screw barrel 82, and a through hole is opened on the top surface of the directional connector 4.

[0040] A top head 83 is fixedly installed on the top of the screw barrel 82, passing through the top through hole of the directional connector 4 and extending above the directional connector 4. The top head 83 has a convex structure. The first stepped surface of the top head 83 is flush with the top surface of the screw barrel 82. The top surface of the directional connector 4 is also slidably connected to the first stepped surface of the top head 83. A top cap 84 is sleeved on the outer wall of the top head 83 and can be detachably connected by a pin 85. The bottom surface of the top cap 84 is slidably connected to the top surface of the directional connector 4. The top cap 84 and the top head 83 clamp the top surface of the directional connector 4.

[0041] The fine-tuning mechanism is achieved by rotating the screw cylinder 82, which allows the screw cylinder 82 to move up and down, thereby driving the directional joint 4 to move up and down, and in turn driving the gun body fixing structure and the gun body to move up and down. The top cap 84 is connected to the top head 83 by a pin 85. The top head 83 is fixedly connected to the screw cylinder 82. When the screw cylinder 82 rotates, the top head 83 and the top cap 84 rotate with the screw cylinder 82. The directional joint 4 is slidably connected to the top head 83 and the top cap 84 respectively, so the directional joint 4 can be rotated freely relative to the nut to adjust the angle.

[0042] The gun barrel fixing mechanism is installed on the directional joint 4. The gun barrel fixing mechanism includes a directional mechanism, a bracket 5 and a gun hoops 6. The directional mechanism is installed on the directional joint 4. The outer cylinder 41 of the directional mechanism is hinged to the directional joint 4. The bracket 5 is fixedly connected to the outer cylinder 41 of the directional mechanism. The gun hoops 6 and the bracket 5 are detachably connected by a fastener. The gun barrel is installed between the bracket 5 and the gun hoops 6. The gun barrel can be fixed by rotating the fastener.

[0043] The steering gear is equipped with a steering gear handwheel 42, which is used to adjust the rotation angle between the steering gear and the steering joint 4. The bracket 5 is also equipped with a scope holder 51.

[0044] The gun barrel fixing mechanism in this embodiment is the structure on an existing mortar mount, and the specific structure will not be described in detail.

[0045] After the gun body is installed, the quick self-locking mechanism performs self-locking. The gun body moves the lifting rod 7 downwards by its own weight. Due to the large friction between the lifting rod 7 and the self-locking body 71, the downward movement of the lifting rod 7 will cause the self-locking body 71 to move downwards. At this time, the outer end face of the self-locking pin 72 contacts the inclined plane. The further down the self-locking pin 72 is, the more it will be pushed inwards by the inclined plane. The inner end face of the self-locking pin 72 gradually approaches the lifting rod 7 until the inner end faces of multiple self-locking pins 72 simultaneously clamp the lifting rod 7, and the lifting rod 7 can no longer move downwards, thus realizing the self-locking of the high and low machine 1.

[0046] When it is necessary to release the self-locking state, the operator holds the screw cylinder 82 and lifts it upwards. The screw rod 81 and the lifting rod 7 fixedly connected to the screw rod 81 will move upwards. At this time, the self-locking body 71 will move upwards with the lifting rod 7, and the self-locking pin 72 will also move upwards. The outer end face of the self-locking pin 72 will no longer contact the inclined surface, and the inner end face of the self-locking pin 72 will no longer clamp the outer wall of the lifting rod 7. At this time, the contact with the outer wall of the lifting rod 7 is released, and the lifting rod 7 can no longer be locked. After the operator releases his hand, the self-locking will be restored by the weight of the gun body itself. This method is only applicable to raising the height and cannot be used to adjust the height downwards.

[0047] Two symmetrically arranged long slots 74 are provided on the high and low outer cylinder 11 near the self-locking body 71. A release handle 75 is installed on the self-locking body 71, which extends through the long slots 74 and to the outside of the high and low mechanism 1.

[0048] In addition to the above-mentioned method of releasing the self-locking state, this device can also be released by pulling up the release handle 75. The operator holds the release handle 75 and pulls it upwards. The self-locking body 71, which is fixedly connected to the release handle 75, moves upwards, and the self-locking pin 72 moves upwards accordingly, releasing its contact with the outer wall of the lifting rod 7. At this time, the operator can hold the screw cylinder 82 and move it up or down to adjust the height. After the operator releases the release handle 75, the device self-locks again by relying on its own weight.

[0049] When a large adjustment of the elevation angle is required, first use the quick adjustment mode to adjust the quick self-locking mechanism to quickly adjust to the approximate position, and then use the fine adjustment mode to rotate the screw 82 to make a small adjustment to achieve a rapid change of elevation angle.

[0050] This invention features an optimized structure, replacing the traditional structure of existing mortar mounts with a triangular structure composed of the left and right outriggers and the elevation mechanism, resulting in stable force distribution. The triangular structure's two-point hinge and one-point sliding lock characteristics improve the efficiency of mortar mount erection and dismantling. It also allows for rapid adjustment of the mortar's firing angle and direction, meeting requirements for portability, high reliability, high serviceability, and rapid aiming operation.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
