DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor are involved in the protection scope of the utility model.

[0027] Embodiment 1

[0028] As Figures 1-4The embodiment shown provides a grounding wire winding device for grounding resistance, which comprises an insulating rod 1 and a fixed winding support 3. The front end of the insulating rod 1 is fixedly connected with a hook 2. The top of the fixed winding support 3 is fixedly connected with a winding column 4. The surface of the winding column 4 is provided with a groove 5. The top of the fixed winding support 3 is fixedly connected with a connecting frame 6. The inner side of the connecting frame 6 is provided with a convenient fixing mechanism 7. The convenient fixing mechanism 7 comprises a fixed shaft 71 fixedly connected to the inner side of the connecting frame 6. The surface of the fixed shaft 71 is rotatably connected with a clamping ring A 72 and a clamping ring B 713. The clamping ring A 72 and the clamping ring B 713 are both semicircular. The side close to the clamping ring A 72 and the clamping ring B 713 is provided with a rubber pad. The insulating rod 1 is clamped by the semicircular clamping ring A 72 and the clamping ring B 713 and the rubber pad on the inner side thereof. The top of the clamping ring A 72 is fixedly connected with a socket 73. The inner wall of the socket 73 is provided with a groove 74. The inside of the groove 74 is provided with a telescopic spring 75. The inside of the groove 74 is slidably connected with an arc block 76 through the telescopic spring 75. The arc surface of the arc block 76 faces the fixed block 78. The depth of the groove 74 is greater than the length of the arc block 76. The arc block 76 can be completely retracted into the groove 74 when the arc surface of the arc block 76 is extruded. One end of the arc block 76 close to the telescopic spring 75 is fixedly connected with a pull rod 77. The top of the clamping ring B 713 is fixedly connected with a fixed block 78. The front end of the fixed block 78 penetrates and is slidably connected with a plug column 79. The side surface of the plug column 79 is fixedly connected with a pressing block 710. One side of the pressing block 710 close to the plug column 79 is fixedly connected with a compression spring 711. One end of the compression spring 711 away from the pressing block 710 is fixedly connected with the fixed block 78. One end of the plug column 79 away from the pressing block 710 is located in the inside of the socket 73 in the initial state. The compression spring 711 is in the compressed state in the initial state. The plug column 79 is driven to leave the inside of the socket 73 when the compression spring 711 rebounds. One end of the plug column 79 away from the pressing block 710 is provided with a clamping groove 712. The opening size of the groove 74 is equal to the opening size of the clamping groove 712. One half of the arc block 76 is located in the clamping groove 712 in the initial state. The plug column 79 cannot leave the socket 73 when the arc block 76 is clamped in the clamping groove 712. The end of the pull rod 77 away from the arc block 76 is provided with an anti-skid block. The pull rod 77 penetrates and is slidably connected with the socket 73. The arc block 76 can be completely retracted into the groove 74 by pulling the pull rod 77 through the anti-skid block. The top of the fixed block 78 is provided with a speed reduction mechanism 8.

[0029] In this embodiment, the insulating rod 1 is passed between the clamping ring A72 and the clamping ring B713, and the clamping rings A72 and B713 are joined together. The insulating rod 1 is clamped by the semi-circular clamping rings A72 and B713 and the rubber pads on their inner sides. Then, the pressure block 710 is pushed to drive the insertion post 79 into the socket 73. The compression spring 711 is compressed. Initially, the arc surface of the arc block 76 is completely retracted into the groove 74 due to the pressure of the insertion post 79. When the slot 712 coincides with the groove 74, the extension spring 75 rebounds and drives the arc block 76 into the slot 712. At this time, the insertion post 79 cannot be separated from the socket 73, thereby making the clamping... The retaining ring A72 and the clamping ring B713 are kept in a clamped state to prevent the fixed winding bracket 3 from falling off the insulating rod 1. This fixes the two sets of fixed winding brackets 3 and the three sets of insulating rods 1. Then the grounding wire can be wound on the groove 5 on the surface of the winding column 4. The entire device can be hung up by the hooks 2 on the three sets of insulating rods 1. When disassembly is required, the pull rod 77 is pulled to drive the arc block 76 to leave the slot 712 and fully retract into the groove 74. At this time, the compression spring 711 will rebound and drive the insertion post 79 to leave the socket 73. At this time, the clamping ring A72 and the clamping ring B713 can be separated, so that the fixed winding bracket 3 falls off the insulating rod 1.

[0030] Example 2

[0031] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The deceleration mechanism 8 includes a bracket 81. One end of the bracket 81 is fixedly connected to the top of the fixed block 78. The other end of the bracket 81 is rotatably connected to a pulley 82. In the initial state, the bottom of the pulley 82 is in close contact with the top of the insertion post 79, and the friction between the pulley 82 and the top of the insertion post 79 is greater than the static friction of the pulley 82. When the insertion post 79 moves, it will drive the pulley 82 to rotate through friction. A square groove 83 is provided on the side of the pulley 82, and a spring spring 84 is provided inside the square groove 83. Inside the square groove 83, a resistance block 85 is slidably connected via a spring 84. In its initial state, the resistance block 85 is completely located within the square groove 83, and the elastic force of the spring 84 is greater than the weight of the resistance block 85. When the resistance block 85 is completely located within the square groove 83, it will not affect the movement of the insertion post 79. However, the weight of the resistance block 85 will not cause it to move out of the square groove 83. The resistance block 85 is made of rubber, and the end of the resistance block 85 away from the spring 84 is uneven. When the uneven end of the rubber resistance block 85 contacts the insertion post 79, it will provide resistance to the movement of the insertion post 79.

[0032] In the process of pushing the pressing block 710 to drive the insertion column 79 to insert into the socket 73, the insertion column 79 moves to drive the pulley 82 to rotate through friction, at this time, the pulley 82 rotates slowly, and when the resistance block 85 is completely located in the square groove 83, the movement of the insertion column 79 is not affected, and in the process of the compression spring 711 rebounding to drive the insertion column 79 to move away from the inside of the socket 73, the movement speed of the insertion column 79 is fast, so that the rotation speed of the pulley 82 is also fast, the centrifugal force generated by the fast rotation of the pulley 82 can throw out the resistance block 85, at this time, when the uneven end of the resistance block 85 made of rubber contacts with the insertion column 79, the movement of the insertion column 79 will be resisted, the movement speed of the insertion column 79 is slowed down, and the rebound of the compression spring 711 drives the insertion column 79 to separate from the socket 73, so that the movement speed is prevented from being too fast to hit the operator.

[0033] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
