Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figures 1 to 4 As shown, the switch maintenance device includes a base 1, a support 2, a clamping component 3, and an adjusting component 4. A guide mechanism is provided on the upper surface of the base 1, and clamping mechanisms are provided at both ends of the upper surface of the base 1. A support mechanism for cable limiting is provided on the back of the base 1. First limiting grooves 11 are provided on both sides of the upper surface of the base 1, and a groove 12 is provided between the two first limiting grooves 11. Both the first limiting grooves 11 and the groove 12 are used to connect the clamping component 3.

[0027] Specifically, the support component 2 is the support mechanism used to limit the cable of the switch. The support component 2 is equipped with a movable structure for adjustment according to the maintenance height of the switch. The support component 2 includes a fixed plate 21 fixed to the middle of the back of the base 1. The fixed plate 21 is designed with an L-shaped structure. Two symmetrically distributed dovetail grooves 22 are opened on the inner side of the fixed plate 21. A screw 23 is connected to the bottom of the fixed plate 21 through a bearing. A movable plate 24 is attached to the inner side of the fixed plate 21. Two symmetrically distributed dovetail sliders 25 are fixed on one side of the movable plate 24. Located within the dovetail groove 22, 5 serves as a guide, ensuring the movable plate 24 moves vertically up and down while preventing it from separating from the fixed plate 21. A screw groove 26 is provided in the middle of the bottom end of the movable plate 24. The upper end of the screw 23 is inserted into the screw groove 26 and connected to it via internal and external threads. Rotating the screw 23 can drive the movable plate 24 to move up and down. A support plate 27 is fixed to the top of the movable plate 24. Multiple equally spaced wire clamping blocks 28 are fixed to the upper surface of the support plate 27. The wire clamping grooves on the wire clamping blocks 28 can clamp and limit the cable of the switch.

[0028] More specifically, clamping members 3 are disposed at both ends of the upper surface of the base 1. Two clamping members 3 cooperate to clamp different models of switches. Each clamping member 3 includes a clamping plate 31 disposed on the upper surface of the base 1. The clamping plate 31 has an L-shaped structure, and first limiting sliders 32 are fixed to both sides of the bottom end of the clamping plate 31. The first limiting sliders 32 are located within the first limiting groove 11, serving a guiding function to prevent the clamping plate 31 from separating from the base 1, while simultaneously ensuring that the clamping plate 31 maintains horizontal linear movement. A protrusion 33 is fixed in the middle of the bottom end. The protrusion 33 is located in the groove 12. The protrusions 33 of the two clamping plates 31 are connected by a spring 34. The spring 34 enables the two clamping plates 31 to automatically clamp and limit the switch. Screw holes are opened through both sides of the bottom end of the clamping plate 31. Positioning studs 35 are connected through the screw holes to limit the clamping plate 31. Second limiting grooves 36 are opened on both sides of the upper end of the clamping plate 31. A toothed groove 37 is provided between the two second limiting grooves 36 for connecting the adjusting component 4.

[0029] More specifically, the adjusting component 4 is installed on the clamping component 3 and is used to adjust the maintenance height of the switch. The adjusting component 4 includes an adjusting plate 41 that is fitted to the outer side of the upper end of the clamping plate 31. The adjusting plate 41 is designed with an L-shaped structure. A second limiting slider 42 is fixed on both sides of one side of the adjusting plate 41. The second limiting slider 42 is located in the second limiting groove 36 and plays a connecting and guiding role to prevent the adjusting plate 41 from separating from the clamping plate 31. At the same time, it keeps the adjusting plate 41 moving vertically up and down. A protrusion 43 is fixed on both sides of the bottom end of the adjusting plate 41. A locking plate 44 is movably connected between the two protrusions 43 through a connecting shaft and a bearing. Both ends of the connecting shaft are provided with torsion springs. One end of the locking plate 44 meshes with the tooth groove 37 and plays a supporting and limiting role, which can limit the adjusting plate 41 to the corresponding height. The locking plate 44 is automatically locked in the tooth groove 37 under the action of the torsion spring. At the same time, moving the locking plate 44 can separate the locking plate 44 from the tooth groove 37 and release the limiting of the adjusting plate 41.

[0030] When this device is in operation, the height of the adjusting plate 41 is first adjusted according to the height at which the switch needs to be repaired. To adjust upwards, simply move the adjusting plate 41 upwards. At this time, the locking plate 44, under the action of the torsion spring, sequentially engages with multiple toothed slots 37. Simultaneously, the locking plate 44 and the toothed slots 37 cooperate to support the adjusting plate 41. To adjust downwards, move the locking plate 44 to separate it from the toothed slots 37, thus releasing the support limit of the adjusting plate 41 until it is adjusted to the appropriate height. Then, turn the screw 23. The screw 23 engages with the screw groove 26 on the movable plate 24, causing the movable plate 24 to move up and down at the fixed plate 21. Move the cable clamping block 28 on the support plate 27 to a suitable height, then place the switch between the two clamping plates 31. The two clamping plates 31 initially clamp the switch under the action of the spring 34. Then, turn the positioning stud 35. The positioning stud 35 cooperates with the screw hole to drive the positioning stud 35 to move downward until the positioning stud 35 contacts the base 1, limiting and fixing the clamping plates 31. This allows the two clamping plates 31 to stably clamp the switch, making it easier for staff to inspect and repair the switch. Then, the multiple cables on the back of the switch are clamped into the cable clamping slots on the cable clamping block 28 to prevent the cables from getting tangled and affecting the subsequent installation of the switch.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
