Description

Technical Field

[0001] This utility model relates to the field of socket wrench technology, specifically a reversible socket wrench for communication chassis. Background Technology

[0002] Communication equipment typically contains multiple detachable functional modules (such as line card modules). These functional modules are detachably installed inside the communication equipment's chassis. Wrenches are installed at both ends of the functional modules, allowing the modules to be plugged in or unplugged.

[0003] A search revealed a Chinese patent (CN212146168U) disclosing a high-strength bidirectional socket wrench reversing mechanism. The mechanism includes a wrench body, a control rod, a D-shaped limiting block, and a driven engaging rotating component. The wrench body comprises a gripping rod and a engaging portion, with the gripping rod fixedly attached to the engaging portion. The engaging portion contains a gear disk rotation groove and a limiting rotation groove that are interconnected. The driven engaging rotating component is rotatably disposed within the gear disk rotation groove. A rotating shaft is located within the limiting rotation groove, and the D-shaped limiting block is mounted on the rotating shaft. The D-shaped limiting block has a D-shaped cross-section. This utility model belongs to the field of hardware tools, specifically providing a high-strength bidirectional socket wrench reversing mechanism that features flexible reversing via the rotation of the D-shaped limiting block, a built-in control rod for reversing, no limitations on operating space, a large torque capacity through the engagement of the boss and the limiting arc groove, and a reasonable structural design.

[0004] The above patents propose that by using a lever to move the control lever, the boss can be driven to cooperate with the D-shaped limit block to achieve the rotation of the socket wrench, which is not limited by the operating space. The boss and the limit arc groove are engaged and connected, which can bear greater torque. However, the lever is exposed in the clearance groove. When operating in a narrow space (such as inside a communication chassis), the hand or surrounding parts can easily touch the lever accidentally, causing the D-shaped limit block to disengage from the preset limit position. The gear disk loses effective constraint and may spin freely or jam in the opposite direction, affecting the tightening accuracy or even damaging the fastener. Therefore, we propose a reversible socket wrench for communication chassis. Utility Model Content

[0005] The technical problem to be solved by this application is that when the paddle is exposed in the clearance groove, the hand or surrounding parts may accidentally touch the paddle during operation in a narrow space, causing the D-shaped limit block to disengage from the preset limit position, the gear disk to lose effective constraint, and the gear may spin freely or jam in the opposite direction, affecting the tightening accuracy or even damaging the fastener.

[0006] To address the aforementioned technical problems, this application provides a reversible socket wrench for a communication chassis, comprising a wrench body and a locking portion, and further comprising:

[0007] A clearance groove is formed on the wrench body. A rotating groove communicating with the locking part is formed on one side of the clearance groove.

This avoids adjustment back due to vibration during use, thus improving adjustment accuracy and efficiency.

[0017] 2. By setting up a connecting groove, a rotating part, a top-impact rod, a trapezoidal slider, a return spring, and a limit rod, the rotation of the rotating part causes the top-impact rod to descend and strike the inclined surface of the trapezoidal slider, causing the trapezoidal slider to slide along the groove and drive the limit rod to engage in the limit hole, thus completing the locking and limiting of the paddle. When changing direction, the limit rod must also be released to better eliminate the risk of accidental contact and enhance the convenience of use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a reversible socket wrench for a communication chassis, including a wrench body 1 and a locking part 2. The locking part 2 is connected to one side of the wrench body 1. It also includes a clearance groove 3 opened on the wrench body 1. A rotating groove 4 communicating with the locking part 2 is opened on one side of the clearance groove 3. A control rod 5 is rotatably arranged in the rotating groove 4. A lever 6 is fixedly connected to one end of the control rod 5 located in the clearance groove 3. The rotating groove 4 allows the control rod 5 to rotate and adjust inside. At the same time, moving the lever 6 can further facilitate the adjustment of the rotating control rod 5.

[0028] The locking part 2 has a gear disk groove, in which a gear disk 9 is rotatably mounted. A wrench connector 8 is fixedly connected to the gear disk 9. A D-shaped limiting block 10 is provided on one side of the gear disk 9 in the locking part 2. A boss 11 is fixedly connected to one end of the control rod 5 near the D-shaped limiting block 10. A locking through hole is provided on the wrench body 1, which penetrates the gear disk groove. The wrench connector 8 is rotatably mounted in the locking through hole and fixedly mounted on the gear disk 9 through the locking through hole and the middle of the gear disk 9. A limiting groove is provided in the locking part 2, which is interconnected with the gear disk groove. A rotating shaft 12 is provided in the limiting groove, and the D-shaped limiting block 10 is mounted on the rotating shaft 12.

[0029] It is worth noting that, in actual use, the wrench connector 8 is snapped onto the part. In the initial state, the lever 6 is set at the center of the clearance groove 3. The lever 6 can be rotated left and right to drive the control rod 5 to rotate in the rotation groove 4, thereby causing the boss 11 to rotate in conjunction with the D-shaped limit block 10 to adjust the rotation, and further rotate its gear disk 9 to realize the turning operation of the socket wrench. Its specific working principle and components can be found in the patent document with publication number CN212146168U, and will not be described in detail here.

[0030] In addition, limit notches 15 are provided on both sides of the inner wall of the clearance groove 3, and an elastic limit shaft 13 is fixedly provided at the bottom of the lever 6. Connecting plates 14 are fixed on both sides of the elastic limit shaft 13. An arc-shaped buckle 19 matching the limit notch 15 is fixedly installed on one side of the bottom end of the connecting plate 14. When the lever 6 is rotated to adjust the direction, when it moves to the limit position, the elastic limit shaft 13 can drive the arc-shaped buckle 19 to automatically engage in the limit notch 15, forming an effective mechanical positioning of the device, avoiding adjustment back due to vibration during use, and improving adjustment accuracy and efficiency.

[0031] Example 2: Please refer to Figure 2-7This utility model provides a technical solution: a reversible socket wrench for a communication chassis, including a limiting hole 24 opened on one side of the lever 6 above the elastic limiting shaft 13, and a groove matching the limiting hole 24 opened on one side of the connecting groove 7 corresponding to the position of the limiting hole 24. Both the groove and the limiting hole 24 are cylindrical, providing effective preconditions for subsequent locking operations.

[0032] Furthermore, a connecting groove 7 is fixedly connected to one side of the lever 6 on the wrench body 1. A locking mechanism is provided in the connecting groove 7. The locking mechanism includes a rotating part 16 rotatably mounted on the top of the connecting groove 7. A moving rod 17 is fixedly connected to the bottom end of the rotating part 16. A striking rod 18 is fixedly provided at the bottom end of the moving rod 17. A trapezoidal slider 21 is provided on the bottom wall of the connecting groove 7 directly below the striking rod 18. A through groove for the rotating part 16 to rotate is opened at the top of the connecting groove 7. An internal thread is provided on the inner wall of the through groove. An external thread matching the internal thread is provided on the outer surface of the rotating part 16. A screw cap is fixedly connected to the top of the rotating part 16. By turning the screw cap, the rotation of the rotating part 16 can be made easier and more convenient. With the mutual matching of the external and internal threads, when the rotating part 16 rotates, the moving rod 17 will drive the striking rod 18 to descend and strike the inclined surface of the trapezoidal slider 21.

[0033] Furthermore, a return spring 22 is fixedly connected to one side of the trapezoidal slider 21. A limiting rod 23 matching the limiting hole 24 is installed on the return spring 22. A sliding groove 20 is provided on the bottom wall of the connecting groove 7. The trapezoidal slider 21 is slidably installed in the sliding groove 20. The sliding groove 20 guides the sliding of the trapezoidal slider 21 and prevents the trapezoidal slider 21 from sliding off course. When the striking rod 18 strikes the trapezoidal slider 21, it causes the trapezoidal slider 21 to move outward along the sliding groove 20, and causes the limiting rod 23 to move out of the slot and into the limiting hole 24 to be locked and fixed. At this time, the return spring 22 is in a compressed state, which enables it to effectively lock and limit the paddle 6. When it is necessary to move the paddle 6, simply turn the cap in the opposite direction to make the rotating part 16 rotate in the opposite direction, so that the moving rod 17 moves upward and drives the top rod 18 to disengage from the trapezoidal slider 21. At this time, the trapezoidal slider 21 is no longer under force, and the return spring 22 extends and resets, so that the trapezoidal slider 21 drives the limit rod 23 to disengage from the limit hole 24, and the rotation adjustment operation of the paddle 6 is carried out. When changing direction, it is also necessary to release the limit rod 23 to better eliminate the risk of accidental contact and enhance the convenience of use.

[0034] Based on the above embodiments, the following is the complete working principle of the above embodiments: When adjusting the direction by rotating the lever 6, when it moves to the limit position, the elastic limit shaft 13 can drive the arc-shaped buckle 19 to automatically engage in the limit notch 15, forming an effective mechanical positioning of the device, avoiding adjustment back due to vibration during use, improving adjustment accuracy and efficiency. Moreover, after each adjustment or before, by turning the nut to rotate the rotating part 16, under the mutual matching action of the external and internal threads, when the rotating part 16 rotates, it will cause the moving rod 17 to drive the striking rod 18 to descend and strike the inclined surface of the trapezoidal slider 21, so that the trapezoidal slider... Block 21 moves outward along the slide groove 20, causing its limiting rod 23 to move out of the slot and into the limiting hole 24 for locking and fixing. At this time, the return spring 22 is in a compressed state, which completes the effective locking and limiting of the paddle 6. When it is necessary to move the paddle 6, simply turn the cap in the opposite direction to make its rotating part 16 rotate in the opposite direction, causing its moving rod 17 to move upward and drive the top rod 18 to disengage from the trapezoidal slider 21. At this time, the trapezoidal slider 21 is no longer under force, and the return spring 22 extends and resets, causing the trapezoidal slider 21 to drive the limiting rod 23 to disengage from the limiting hole 24, so as to carry out the rotation adjustment operation of the paddle 6. When changing direction, it is also necessary to release the limiting rod 23 to better eliminate the risk of accidental contact and enhance the convenience of use.
