Description

Technical Field

[0001] This utility model relates to the field of ratchet wrenches, and in particular to a novel valve-operating ratchet wrench. Background Technology

[0002] A ratchet wrench is a hand tool whose core component is the ratchet mechanism, mainly composed of a ratchet and a pawl. The ratchet is a toothed disc, and the pawl is a small, movable part that engages with the ratchet's teeth. When the wrench handle is turned in one direction, the pawl slides on the ratchet teeth, allowing the ratchet to rotate smoothly and thus rotating the socket to tighten or loosen an object. When the wrench handle is turned in the opposite direction, the pawl engages the ratchet teeth, preventing the ratchet from reversing. This allows for continuous unidirectional operation without fully resetting the wrench. Furthermore, the wrench can be connected to the valve stem via the connecting sleeve at its head, facilitating valve operation even in confined spaces.

[0003] In existing technologies, to ensure that valves can operate stably and reliably under harsh conditions such as high pressure, high temperature, or high corrosion, valve designs often employ robust materials and complex sealing structures. While this ensures the functionality and durability of the valve, it also significantly increases the resistance to opening and closing the valve. Ordinary ratchet wrenches are generally of fixed length and cannot provide sufficient force, requiring operators to apply a large torque to turn the valve, reducing the convenience and efficiency of operation. Therefore, a new type of valve operating ratchet wrench is needed. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a new type of valve operating ratchet wrench that can extend the overall length of the device. According to the lever principle, this allows the valve to be rotated with less force, saving the operator's effort and improving the convenience and efficiency of operation.

[0005] This utility model also provides a novel valve operating ratchet wrench, comprising a ratchet wrench and an internally threaded sleeve. A connecting block is fixedly connected to the side surface of the internally threaded sleeve, and a handle is rotatably connected to the outer surface of the connecting block. A movable block is threadedly connected to the inner surface of the internally threaded sleeve, and a movable rod is fixedly connected to the side surface of the movable block. A bearing block is fixedly connected to the end of the movable rod away from the movable block, and a connecting rod is rotatably connected to the upper part of the bearing block. The outer surface of the connecting rod is fixedly connected to the ratchet wrench, and a connecting sleeve is provided on the ratchet wrench.

[0006] Two gears are fixedly connected to the connecting rod. A guide rod is fixedly connected to the inner surface of the bearing block. A slider is slidably connected to the outer surface of the guide rod. A movable ring is fixedly connected to the slider. Two fixed teeth are fixedly connected to the movable ring. The two fixed teeth mesh with the two gears respectively. A spring is slidably sleeved on the outer surface of the guide rod.

[0007] According to the novel valve-operating ratchet wrench, one end of the spring is fixedly connected to the side surface of the slider, and the end of the spring away from the slider is fixedly connected to the inner side wall of the bearing block, so that the fixed teeth can quickly mesh with the gear.

[0008] According to the novel valve operating ratchet wrench, a limiting groove is provided on the handle, and the outer surface of the connecting block is rotatably connected to the limiting groove, so that the internal threaded sleeve can rotate without disengaging from the handle.

[0009] According to the novel valve-operating ratchet wrench, the side surface of the handle contacts the internal threaded sleeve, and the outer surface of the movable rod is slidably connected to the internal threaded sleeve.

[0010] According to the novel valve-operating ratchet wrench, the two gears are in contact with the support block on their respective sides, and the inner surface of the moving ring is in contact with the support block.

[0011] According to the novel valve operating ratchet wrench, a groove is provided on the bearing block, and the outer surface of the slider is slidably connected to the groove, so that the slider can move smoothly.

[0012] According to the novel valve-operating ratchet wrench, the guide rod passes through the slider, and the side surface of the fixed tooth contacts the bearing block.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. By using the internal threaded sleeve, moving block and movable rod, the overall length of the device can be extended by rotating the internal threaded sleeve. According to the lever principle, the longer the device is, the farther the force is from the fulcrum. This allows the valve to be rotated with less force, thus saving the operator's effort and improving the convenience and efficiency of operation.

[0015] 2. Through the design of the moving ring, gears and fixed teeth, the ratchet wrench can be released by operating the moving ring, thereby rotating the ratchet wrench to adjust its angle. This allows the device to be adjusted to a suitable force angle according to different environments, thus increasing the overall practicality of the device.

The outer surface of the connecting rod 8 is fixedly connected to the ratchet wrench 1. A connecting sleeve 17 is provided on the ratchet wrench 1. Under the action of the connecting sleeve 17, the entire device can be connected to the valve stem of the valve, thereby realizing the connection between the entire device and the valve. A limiting groove 16 is provided on the handle 4, and the outer surface of the connecting block 3 is rotatably connected to the limiting groove 16, so that the internally threaded sleeve 2 and the connecting block 3 can rotate without detaching from the handle 4.

[0028] Two gears 9 are fixedly connected to the connecting rod 8. The sides of the two gears 9 that are close to each other are in contact with the support block 7. A guide rod 10 is fixedly connected to the inner surface of the support block 7. A slider 11 is slidably connected to the outer surface of the guide rod 10. A moving ring 12 is fixedly connected to the slider 11. The inner surface of the moving ring 12 is in contact with the support block 7. Two fixed teeth 13 are fixedly connected to the moving ring 12. The two fixed teeth 13 mesh with the two gears 9 respectively. The guide rod 10 passes through the slider 11. The side surface of the fixed teeth 13 is in contact with the support block 7. A spring 14 is slidably sleeved on the outer surface of the guide rod 10. One end of the spring 14 is fixedly connected to the side surface of the slider 11. The end of the spring 14 away from the slider 11 is fixedly connected to the inner side wall of the support block 7. Under the action of the spring 14, the fixed teeth 13 can quickly mesh with the gears 9. A groove 15 is opened on the support block 7. The outer surface of the slider 11 is slidably connected to the groove 15. The slider 11 can move smoothly through the reserved groove 15.

[0029] Working Principle: The device can be connected to the valve via the connecting sleeve 17 on the ratchet wrench 1. When the overall length of the device needs to be changed, hold the handle 4 with one hand and rotate the internal threaded sleeve 2 with the other hand. The rotating internal threaded sleeve 2 drives the connecting block 3 to rotate within the limiting groove 16. Since the device is already connected to the valve, the end closest to the valve cannot move. Therefore, the internal threaded sleeve 2 moves via the moving block 5 during rotation, realizing the movement of the internal threaded sleeve 2, the connecting block 3, and the handle 4. This allows the overall length of the device to be changed, enabling the device to move. According to the lever principle, the longer the lever, the easier it is to overcome the resistance generated by the heavy object, thus reducing the force required to operate the object and achieving a labor-saving effect. After adjusting to the appropriate length, the valve can be operated through the device. When the device is finished, rotating the internal threaded sleeve 2 in the opposite direction reduces the overall length of the device. Pulling the moving ring 12 causes the moving ring 12 to drive the slider 11 and the fixed teeth 13 to move. As the slider 11 moves along the guide rod 10, it gradually compresses the spring 14, keeping it taut. When the moving fixed tooth 13 no longer meshes with the gear 9, the restriction on the ratchet wrench 1 and its structure is released. Then, by rotating the ratchet wrench 1, the ratchet wrench 1, connecting sleeve 17, connecting rod 8, and gear 9 can rotate around the connecting rod 8 as the central axis, thereby adjusting the angle of the ratchet wrench 1. When the ratchet wrench 1 is adjusted to... After adjusting to the appropriate angle, align the two teeth on gear 9 with the fixed tooth 13, then release the moving ring 12, causing the spring 14 to spring back without being compressed. The spring 14 then drives the slider 11, the moving ring 12, and the fixed tooth 13 to reset. When the fixed tooth 13 re-engages with gear 9, gear 9 can no longer rotate, thus restricting and fixing the ratchet wrench 1, preventing it from moving, and completing the angle adjustment of the ratchet wrench 1, increasing the overall practicality of the device.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
