[0002] In the routine maintenance of artillery, the disassembly of the breechblock and the assembly of the firing pin are crucial steps, directly affecting the performance and safety of the artillery. Among these, the 155mm vehicle-mounted howitzer, as an important piece of artillery equipment, presents a significant challenge in disassembling its breechblock and firing pin cover. Current technology typically utilizes a special wrench for the firing pin cover. However, the firing pin cover of the 155mm vehicle-mounted howitzer has a strong spring force, making disassembly by a single person using only a firing pin cover wrench extremely difficult. This affects the efficiency of artillery maintenance and may also damage artillery components due to excessive force or improper operation, thereby impacting the artillery's service life and combat performance.

[0003] Therefore, in order to improve the efficiency and quality of daily artillery maintenance, there is an urgent need for a more convenient, efficient and safe tool for removing the breechblock firing pin cover to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a disassembly tool that can safely and quickly remove the firing pin cover of a 155mm vehicle-mounted howitzer.

[0005] This utility model provides a disassembly tool, including a crossbeam with symmetrical pull claws at both ends.

[0028] Example

[0029] A disassembly tool, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a crossbeam 1, with pull claws 2 symmetrically arranged at both ends of the crossbeam 1. A handle 4 is rotatably connected to the crossbeam 1. A guide sleeve 5 is provided on the crossbeam 1. A pressure beam 6 that can slide up and down is provided inside the guide sleeve 5. The handle 4 is connected to the pressure beam 6 through a connecting rod 7. A top rod 8 is provided below the pressure beam 6. The bottom end of the top rod 8 extends out of the guide sleeve 5 and can rotate inside the guide sleeve 5.

[0030] The pull claw 2 includes a fixedly connected vertical rod and claw hooks 201. The vertical rod and claw hooks 201 are integrally formed, and the claw hooks 201 of the two pull claws 2 are arranged opposite each other. In use, they are used to hook into the grooves on both sides of the breechblock body to ensure the safety of the disassembly tool. The tops of the two pull claws 2 are fixedly connected to both ends of the crossbeam 1 by fixing bolts 3. In use, the fixing bolts 3 can be loosened first, and then tightened after the claw hooks 201 are hooked into the grooves of the breechblock body to ensure the stability of the entire tool and prevent the disassembly tool from shaking and causing force loss during operation.

[0031] Connecting plates 101 are fixed to both sides of one end of the crossbeam 1. The upper part of the connecting plates 101 is rotatably connected to one end of the handle 4 via a rotating shaft. A cylindrical guide sleeve 5 with an open bottom is fixed on the crossbeam 1. The central axis of the guide sleeve 5 coincides with the center point of the crossbeam 1. The top of the guide sleeve 5 is provided with a groove that mates with the crossbeam 1. The crossbeam 1 is placed directly in the groove and then welded and fixed.

[0032] The guide sleeve 5 has two symmetrically arranged sliding grooves 501 along its sidewall in the vertical direction. A pressure beam 6, perpendicular to the crossbeam 1, is located inside the guide sleeve 5, and its two ends slide up and down along the two sliding grooves 501 respectively. Both ends of the pressure beam 6 are fixed to connecting rods 7 outside the guide sleeve 5. Two symmetrically arranged fixing plates 401 are provided at the bottom of the handle 4. The upper parts of the two connecting rods 7 are rotatably connected to the fixing plates 401 via a rotating shaft, and the lower parts of the connecting rods 7 are fixedly connected to the pressure beam 6. In this embodiment, the pressure beam 6 can be a cylindrical pin.

[0033] The push rod 8 is located inside the guide sleeve 5, below the pressure beam 6. The bottom end of the push rod 8 extends outside the guide sleeve 5. A clamp is fitted around the outside of the push rod 8, located inside the guide sleeve 5. This clamp ensures the stability of the push rod 8 during its vertical movement. Figure 5 As shown, the top rod 8, from top to bottom, includes a fixedly connected limiting block 801, a first rod body 802, a second rod body 803, and a screwdriver head 804. The limiting block 801, the first rod body 802, and the second rod body 803 are all cylindrical, and their central axes are aligned. The diameter of the limiting block 801 is larger than the diameter of the first rod body 802 and also larger than the inner diameter of the clamp. When the top rod 8 moves to its lowest position, the limiting block 801 is located at the top of the clamp, preventing the top rod 8 from falling out of the guide sleeve 5. The diameter of the second rod body 803 is larger than the diameter of the first rod body 802, and the clamp is engaged with the outside of the first rod body 802.

[0034] like Figure 6 As shown, the clamp includes two symmetrically arranged clamping blocks 9, each clamping block 9 being an arc-shaped ring equal to a semicircle. An arc-shaped plate 901 is fixed to the outer bottom end of each clamping block 9. In use, the two clamping blocks 9 are symmetrically clamped onto the outside of the first rod body 802, with their ends fitting together. The two clamping blocks 9 should not be too tight when clamped onto the outside of the first rod body 802; it must be sufficient to ensure that the top rod 8 can slide up and down when the pressure beam 6 is pressed down, and also to ensure that the top rod 8 can rotate. The bottom end of the inner wall of the guide sleeve 5 is provided with a groove that matches the shape of the clamp, and the clamp fits perfectly into the groove. The outer wall of the clamping block 9 fits tightly against the inner wall of the guide sleeve 5.

[0035] The bottom end of the guide sleeve 5 is equipped with a locking nut 10, which is used to limit the clamp and prevent it from falling off. The bottom end of the guide sleeve 5 is provided with an external thread that mates with the locking nut 10, such as... Figure 4 As shown, a support portion 1001 is fixed to the inner wall of the locking nut 10. The support portion 1001 is located at the bottom of the threaded groove of the locking nut 10 and is supported by the arc-shaped plate 901 of the clamping block 9 to maintain stability. The support portion 1001 can be an annular plate or multiple protrusions spaced apart, or other shapes are also possible. It should be noted that the end of the support portion 1001 away from the inner wall of the locking nut 10 protrudes from the threaded groove, which can effectively support the arc-shaped plate 901.

[0036] The inner diameter of the support part 1001 of the locking nut 10 is larger than the diameter of the limiting block 801 at the top of the push rod 8. When assembling the guide sleeve 5 and the push rod 8, the locking nut 10 is put on the first rod body 802, and then the two clamping blocks 9 are clamped on the outside of the first rod body 802 and put into the inside of the guide sleeve 5 together, so that the clamping blocks 9 are located in the groove at the bottom of the guide sleeve 5. Then the locking nut 10 and the guide sleeve 5 are tightened and fixed.

[0037] The bottom of the screwdriver 804 is provided with a protrusion 805 that mates with the groove on the firing pin cover of the breechblock. In use, the protrusion 805 is snapped into the groove of the firing pin cover. The screwdriver 804 can be fixed to the second rod 803 by means of a threaded connection. In use, it can be replaced according to the size and shape of the groove of different types of firing pin covers, thereby expanding the range of applications.

[0038] The second rod 803 of the push rod 8 is provided with a lever hole 806. When in use, the lever is inserted into the lever hole 806 to facilitate the rotation of the push rod 8. The lever can be a round rod of a certain length that matches the lever hole 806, or other tools, to facilitate the rotation of the push rod 8. Alternatively, a wrench can be used to directly hold the second rod 803 for rotation.

[0039] The design of the length of sleeve 5, the length of push rod 8, the position of slide groove 501 and the height of pull claw 2 should meet the following requirements: When the protrusion 805 at the bottom of push rod 8 is inserted into the groove of firing pin cover, the top of push rod 8 needs to contact pressure beam 6, and pressure beam 6 is located in the upper half or top of slide groove 501.

[0040] The disassembly tool provided by this utility model is used as follows: First, hook the claw hooks 201 of the two pull claws 2 into the groove of the breechblock body, and at the same time ensure that the protrusion 805 on the screwdriver head 804 of the push rod 8 is stuck in the groove of the firing pin cover. At this time, the bottom of the push rod 8 is in close contact with the pressure beam 6. The operator presses down the handle 4 with force. Under the action of the connecting rod 7, the pressure beam 6 moves down along the slide groove 501. During the downward movement of the pressure beam 6, it will press down the push rod 8 and move down. At the same time, the push rod 8 presses down the firing pin cover. When the firing pin cover is pressed down to the position, maintain the pressure and do not release the handle 4. At the same time, insert the wrench into the wrench hole 806 or wrench the second rod body 803 and rotate it 90°. The spring on the firing pin cover generates elastic deformation and torque during the pressing and rotation of the firing pin cover. Finally, release the handle 4 and the firing pin cover will spring open, completing the disassembly of the firing pin cover. During the process of the firing pin cover being popped open, the entire disassembly tool remains stable because the pull claw 2 is stabilizing in the groove of the latch body. The push rod 8 rotates in the opposite direction and moves upward, but the protrusion 805 on the screwdriver head 804 is still stuck in the groove of the firing pin cover, so the firing pin cover will not be popped off.

[0041] The disassembly tool provided by this utility model can quickly and safely disassemble the firing pin cover, requiring only one person to operate. The crossbeam, handle, connecting rod, and pressure beam utilize the lever principle; simply press down on the handle, and the pressure beam will easily press down on the top rod and firing pin cover, making operation simple and labor-saving. The guide sleeve, clamp, and locking nut ensure that the top rod can move up and down and rotate stably. The pull claw and crossbeam ensure that the entire tool is stably locked in the groove of the latch body, ensuring the safety and reliability of the firing pin cover disassembly operation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 therein. Such 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 this utility model.
