[0037] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment.

[0038] As Figure 1 , Figure 2 , Figure 3 As shown in the utility model provides a kind of applied to power distribution network construction's climbing safety slide piece first embodiment, in this embodiment, including slide piece main body 10, slide piece main body 10 is long strip structure, its both ends are equipped with connecting hole, wherein, slide piece main body 10 is provided with safety belt connecting piece 11, safety belt 12, locking mechanism 20 and fixed support 30, safety belt connecting piece 11 is connected slide piece main body 10 by connecting hole, safety belt connecting piece 11 is used to connect safety belt 12 and slide piece main body 10, locking mechanism 20 is arranged on the side of slide piece main body 10, is used to engage with the surface of pole to provide grip, locking mechanism 20 includes at least one spiral locking piece 21, locking piece 21 has spiral edge, and the central axis of each locking piece 21 is parallel to the central axis of slide piece main body 10;Fixed support 30 is connected with slide piece main body 10, is used to fix the position of locking mechanism 20, and fixed support 30 includes at least two support arms 31, and support arm 31 is symmetrically distributed at the both sides of slide piece main body 10 respectively, and locking mechanism 20 is arranged in the internal space of fixed support 30.

[0039] Spiral locking mechanism is located in the side of slide piece main body, usually in the upper portion or one side of slide piece main body, to facilitate contact with the surface of pole and provide grip. Spiral locking piece is made of high-hardness metal or alloy material, which improves its wear resistance and strength and prolongs the service life of the device.

[0040] In the above technical scheme, the number of locking pieces is one or more, and multiple locking pieces are arranged on the both sides of the slide piece main body, and the number of spiral turns of the locking piece is more than 3.

[0041] Further, in the above technical scheme, the spiral radius of locking piece 21 gradually decreases or increases.

[0042] The spiral radius of locking piece gradually decreases or increases, which utilizes the self-locking effect in physics. When the locking piece rotates along the surface of the pole, due to the change of spiral radius, the locking piece and the surface of the pole will generate a progressive engagement force.

[0043] When the spiral radius of the locking piece gradually decreases, the locking piece will penetrate the surface of the pole more and more deeply with rotation, forming a wedge-like effect, thereby providing stronger grip. Conversely, when the spiral radius gradually increases, the locking piece will gradually loosen the surface of the pole during rotation.

[0044] Due to the change of the spiral radius, the locking piece can adapt to different diameters of the pole. No matter how the diameter of the pole changes, the locking piece can find the best bite point through the change of the spiral radius.

[0045] When the diameter of the pole becomes larger, the design of gradually increasing spiral radius can make the locking piece better adapt to the larger diameter; on the contrary, when the diameter of the pole becomes smaller, the design of gradually decreasing spiral radius can make the locking piece better adapt to the smaller diameter.

[0046] Further, in the above technical solution, the inclination angle of the spiral edge of the locking piece 21 ranges from 5° to 45°.

[0047] Further, in the above technical solution, the angle between the support arm 31 and the slide body 10 ranges from 85° to 95°.

[0048] The protruding part of the support arm on both sides of the slide body is connected with the fixed support, and structurally supports the spiral locking mechanism.

[0049] Further, in the above technical solution, the slide body 10 is provided with a body frame and a sliding guide rail, and the sliding guide rail is arranged on one side of the body frame and used to guide the slide body 10 to move up and down along the pole.

[0050] Further, in the above technical solution, the distance between the locking mechanism 20 and the slide body 10 is 10mm to 50mm.

[0051] Further, in the above technical solution, the support arm 31 is connected with the fixed support 30 through at least two connection points, and the connection points adopt one of welding, riveting or bolt connection.

[0052] The specific connection mode between the support arm and the fixed support is:

[0053] The fixed support is provided with a groove or a hole matched with the support arm, and the support arm is inserted into the groove or the hole and fixed through a fastener to ensure the stability of the support arm;

[0054] The connection point between the support arm and the fixed support is located at the lower part of the fixed support, so as to ensure that the support arm can effectively transmit external force to the fixed support, thereby stabilizing the locking mechanism.

[0055] Further, in the above technical solution, the support arm 31 is arranged below the locking mechanism 20, the top of the support arm 31 is in contact or close contact with the bottom of the locking mechanism 20, and the distance between the support arm 31 and the locking mechanism 20 is 5mm to 30mm.

[0056] The cooperation mode between the support arm and the spiral locking mechanism is:

[0057] The top of the support arm is provided with a groove or a protrusion, which matches the bottom of the spiral locking mechanism, so as to enhance the contact stability between the two;

[0058] The design of the support arm enables it to withstand the pressure from the spiral locking mechanism, thereby preventing the locking mechanism from being deviated or deformed when being stressed.

[0059] Further, in the above technical solution, the fixed support 30 is connected with the slide main body 10 through at least two fixed points, and the fixed points adopt one of welding and bolt connection.

[0060] Specifically, the principle of the utility model is:

[0061] Self-locking effect:

[0062] One of the core technical principles of the utility model is the self-locking effect. The design of the spiral locking piece utilizes the self-locking property of the spiral structure. When the locking piece rotates along the surface of the telegraph pole, due to the change of the spiral radius, a progressive biting force will be generated between the locking piece and the surface of the telegraph pole. Specifically:

[0063] Spiral radius decreases: when the spiral radius gradually decreases, the locking piece will penetrate deeper and deeper into the surface of the telegraph pole, forming a wedge-like effect, thereby providing stronger grip. This design enables the locking piece to tightly bite the surface of the telegraph pole, preventing the slide from accidentally falling during the climbing process.

[0064] Spiral radius increases: when the spiral radius gradually increases, the locking piece will gradually loosen the surface of the telegraph pole, allowing the slide to move smoothly upwards or downwards. This design enables the operator to easily adjust the position of the slide, improving the flexibility of operation;

[0065] Friction force enhancement:

[0066] The change of the spiral radius also changes the contact area and angle between the locking piece and the surface of the telegraph pole. When the spiral radius gradually decreases, the contact area increases, and the friction force increases; when the spiral radius gradually increases, the contact area decreases, and the friction force decreases. This design enables the locking piece to provide appropriate friction force under different conditions, ensuring the stability and safety of the slide;

[0067] Adapt to telegraph poles of different diameters:

[0068] The change of the spiral radius enables the locking piece to adapt to telegraph poles of different diameters. Regardless of the change in the diameter of the telegraph pole, the locking piece can find the optimal biting point through the change of the spiral radius. Specifically:

[0069] Pole diameter increases: When the pole diameter increases, the design of gradually increasing spiral radius allows the locking piece to better adapt to larger diameters, ensuring stable grip on large diameter poles;

[0070] Pole diameter decreases: When the pole diameter decreases, the design of gradually decreasing spiral radius allows the locking piece to better adapt to smaller diameters, ensuring stable grip on small diameter poles;

[0071] Stability improvement:

[0072] By setting the fixed support and support arm, the utility model ensures the position stability of the spiral locking mechanism. Specifically:

[0073] Fixed support: The design of the fixed support ensures the position stability of the spiral locking mechanism, improving the overall stability of the device. The fixed support is connected to the slide body through a fixed point, ensuring the stability of the locking mechanism;

[0074] Support arm: The support arm is set on the fixed support to further reinforce the position of the spiral locking mechanism. The support arm is connected to the fixed support through a connection point to ensure the firmness of the support arm. The support arm is located on the protruding part on both sides of the slide body, providing additional support force;

[0075] Reducing wear and tear:

[0076] The utility model optimizes the design of the spiral locking piece, reducing the direct hard collision between the locking piece and the surface of the pole. Specifically:

[0077] Spiral locking piece: The design of the spiral locking piece allows the contact between the locking piece and the surface of the pole to be gradual, reducing direct hard collision, thereby reducing wear and tear on the locking piece and the surface of the pole, prolonging the service life of the device;

[0078] High hardness material: The spiral locking piece is made of high hardness metal or alloy material, improving its wear resistance and strength, further enhancing the durability of the locking piece.
