Description

Technical Field

[0001] The utility model relates to the technical field of double-guide-rail rope wheel type lifters, in particular to a steel wire tensioning structure. Background Art

[0002] The double rail sheave lift is a specific lifting device, whose design and functional features combine the stability of double rails with the flexibility of a sheave lift.

[0003] The double-track rope pulley lifter is a lifting device widely used in vehicle window systems. With its unique double-track design and rope pulley lifting principle, it provides efficient and stable lifting effects. However, the existing double-track rope pulley lifter has a very long wire rope. During use, the wire rope will become thinner in diameter and longer in length, causing the wire rope of the lifter assembly to become loose, thereby affecting the amount of activity of the glass reverse lifting. Therefore, we propose a new wire tensioning structure. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing double-guide rope wheel lifter in the prior art has a very long steel wire rope, and during use, the steel wire rope will become thinner in diameter and longer in length, causing the steel wire rope of the lifter assembly to become loose, thereby affecting the amount of reverse lifting activity of the glass.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a steel wire stretching and tensioning structure, including a lifter body, a sliding port is provided on one side of the lifter body, an automatic tensioning component is provided inside the lifter body, the automatic tensioning component includes a first rack, the first rack is provided at the inner bottom of the lifter body, a one-way block is attached to the surface of the first rack, a clamping block is connected to the top of the one-way block, a steel wire rope body is inserted through the inside of the clamping block, a fixed block is fixedly connected to one side of the one-way block, a compression spring is sleeved on the surface of the fixed block, and an adjusting head is connected to one side of the fixed block.

[0006] Furthermore, the one-way block and the clamping block are fixedly connected, and the position and size of the one-way block match the position and size of the first rack.

[0007] Furthermore, the first rack is meshed with the one-way block, and the regulating head is elastically connected to the lifter body via a compression spring.

[0008] Furthermore, the first rack is a one-way rack.

[0009] Furthermore, a disassembly assembly is provided on one side of the fixing block, and the disassembly assembly includes threaded holes, and four groups of threaded holes are annularly opened on the outer surface of one side of the fixing block close to the adjusting head.

[0010] Furthermore, four groups of slots are provided in an annular shape inside the adjusting head, and a group of threaded rods are inserted into the interior of each group of slots.

[0011] Furthermore, the position and size of the slotted hole match the position and size of the threaded hole, and the threaded rod passes through the slotted hole to form a threaded connection with the threaded hole.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the main body of the steel wire rope will become loose during long-term use. At this time, the compression spring will push the clamp block and the one-way block to retract backwards through its own elasticity, thereby driving the main body of the steel wire rope to retract, so that the main body of the steel wire rope always remains in a tensioned state, avoiding the problem that the main body of the existing steel wire rope will become loose after long-term use, thereby affecting the amount of activity of the glass reverse lifting.

[0014] 2. In the utility model, when the elasticity of the compression spring is reduced or even lost after long-term use, the threaded rod can be taken out, the adjusting head can be removed, and the compression spring can be replaced to avoid the problem that the elasticity of the compression spring is reduced and the lifter body cannot be used normally, thereby increasing the service life of the lifter body.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a wire tensioning structure, including a lifter body 1, a sliding port 2 is provided on one side of the lifter body 1, an automatic tensioning assembly 3 is provided inside the lifter body 1, and the automatic tensioning assembly 3 includes a first rack 301, the first rack 301 is provided at the inner bottom of the lifter body 1, a one-way block 303 is attached to the surface of the first rack 301, a clamping block 302 is connected to the top of the one-way block 303, a wire rope body 304 is inserted through the inside of the clamping block 302, and the one-way block 303 is provided at the bottom of the one-way block 303. A fixed block 307 is fixedly connected to one side, a compression spring 305 is sleeved on the surface of the fixed block 307, an adjusting head 306 is connected to one side of the fixed block 307, a fixed connection is formed between the one-way block 303 and the clamping block 302, the position and size of the one-way block 303 match the position and size of the first rack 301, the first rack 301 and the one-way block 303 are meshed, the adjusting head 306 is an elastic structure between the compression spring 305 and the lifter body 1, and the first rack 301 is a one-way rack.

[0024] The effect achieved by the entire embodiment 1 is that the length of the wire rope main body 304 will become longer during long-term use, while the length of the wire rope main body 304 protective tube remains unchanged, causing the wire rope main body 304 to relax. At this time, the compression spring 305 will push the adjusting head 306 outward through its elastic force, thereby enabling the adjusting head 306 to drive the clamping block 302 and the one-way block 303 to move backward. While the one-way block 303 moves, it will also mesh with the first rack 301 and rotate. When the movement exceeds one tooth pitch, it will also mesh with the next tooth of the first rack 301, thereby achieving the purpose of tightening the wire rope main body 304, avoiding the problem that the existing wire rope main body 304 will become loose after long-term use, thereby affecting the activity of the glass reverse lifting.

[0025] Embodiment 2, as Figure 1 , Figure 2 and Figure 5 As shown, a disassembly assembly 4 is provided on one side of the fixed block 307, and the disassembly assembly 4 includes threaded holes 401. Four groups of threaded holes 401 are annularly opened on the outer surface of one side of the fixed block 307 close to the adjusting head 306. Four groups of slot holes 402 are annularly opened inside the adjusting head 306. A group of threaded rods 403 are inserted inside each group of slot holes 402. The position and size of the slot holes 402 match the position and size of the threaded holes 401. After the threaded rods 403 pass through the slot holes 402, they form a threaded connection with the threaded holes 401.

[0026] The effect achieved by the entire embodiment 2 is that when the compression spring 305 has reduced elasticity or even lost it after being used for a long time, the threaded rod 403 can be rotated in the opposite direction at this time so that the threaded rod 403 can be taken out from the threaded hole 401, and then the adjusting head 306 can be removed and the compression spring 305 can be replaced. After the compression spring 305 is replaced, the slot 402 of the adjusting head 306 is aligned with the threaded hole 401, and the threaded rod 403 is passed through the slot 402 and then fixed with the threaded hole 401 by threads. In this way, the problem of reduced elasticity of the compression spring 305 and the inability to use the lifter body 1 normally is avoided, thereby improving the service life of the lifter body 1.

[0027] Working principle: During long-term use, the wire rope main body 1 will become loose. At this time, the compression spring 305 will push the clamp block 302 and the one-way block 303 to retract backwards through its own elasticity, thereby driving the wire rope main body 304 to retract, so that the wire rope main body 304 always remains in a tensioned state, avoiding the problem that the existing wire rope main body 304 will become loose after long-term use, thereby affecting the amount of activity of the glass reverse lifting. When the compression spring 305 is used for a long time, its elasticity will be reduced or even lost. At this time, the threaded rod 403 can be taken out, and then the adjusting head 306 can be removed, and the compression spring 305 can be replaced, so as to avoid the problem that the elasticity of the compression spring 305 is reduced and the lifter main body 1 cannot be used normally, thereby improving the service life of the lifter main body 1.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
