Description

Technical Field

[0001] This utility model relates to the field of guide bracket technology, specifically a telescopic guide bracket. Background Technology

[0002] Guide supports are key components in steel rolling production, ensuring precise and stable rolling. Their main function is to provide stable support and accurate positioning for the guide device. Made of high-strength alloy materials, they possess excellent rigidity, wear resistance, and impact resistance, capable of withstanding the intense friction and mechanical impact generated when the workpiece passes through at high speed. The design of the guide support must strictly adhere to rolling process requirements, ensuring a perfect match with the guide device through precision machining. This prevents surface defects such as scratches and folds on the workpiece caused by guiding deviations. Their optimized structure effectively disperses rolling forces, avoiding deformation or fracture caused by localized stress concentration, thus ensuring long-term stability. In high-temperature rolling environments, the guide support maintains dimensional stability through material properties and heat treatment processes, preventing thermal expansion from affecting the positioning accuracy of the guide device. Furthermore, their surface undergoes special treatment to reduce oxide scale adhesion, lowering maintenance frequency and providing reliable assurance for continuous and efficient rolling.

[0003] The prior art patent document CN221790561U provides a telescopic guide bracket, which realizes the function of adjusting the position of the rubber guide wheel according to the rolling steel output position, thereby improving the practicality of the device; However, in the existing technology, if the guide bracket cannot be extended or retracted when dealing with the rapid switching of different specifications of rolled products, it needs to be manually disassembled and replaced, which is a bit cumbersome and affects work efficiency. Therefore, we need a telescopic guide bracket. Utility Model Content

[0016] 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.

[0017] This utility model embodiment provides a telescopic guide bracket, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a support base 1, a telescopic assembly 2 on top of the support base 1, a threaded sleeve 3 on top of the telescopic assembly 2, a support assembly 4 on top of the threaded sleeve 3, and a support rod 5 on top of the support assembly 4. The telescopic assembly 2 includes a support sleeve 201, the bottom of which is fixedly connected to the top of the support base 1. One end of the support sleeve 201 has a cylindrical groove 202. A retaining ring 203 is fixedly connected to the bottom of the threaded sleeve 3, and the outer wall of the retaining ring 203 has an external thread 204. The outer wall of the external thread 204 is threadedly connected to a fixing sleeve 205. The inner wall of the fixing sleeve 205 is provided with an internal thread 206. The threaded sleeve 3 is fixedly connected to a guide rod 207. When the guide bracket needs to be adjusted, the fixing sleeve 205 can be directly screwed on to disengage the internal thread 206 from the external thread 204, thereby disengaging the fixing sleeve 205 from the support sleeve 201. At this time, the support sleeve 201 can be moved to a suitable height. Then, the fixing sleeve 205 is screwed on to press the fixing ring 203 to fix the support sleeve 201, thus completing the height adjustment.

[0018] Furthermore, such as Figure 2 As shown, the retaining ring 203 forms a fixing structure with the retaining sleeve 205 through the external thread 204, and the outer diameter of the external thread 204 matches the inner diameter of the internal thread 206. The outer wall of the external thread 204 fits against the inner wall of the internal thread 206, so that when the retaining sleeve 205 is rotated, the internal thread 206 and the external thread 204 are threadedly connected, thereby squeezing the retaining ring 203 and improving the fixing effect.

[0019] Furthermore, such as Figure 2 and Figure 3 As shown, the threaded sleeve 3 forms a limiting structure with the support sleeve 201 through the guide rod 207, and the size of the guide rod 207 matches the size of the cylindrical groove 202. The outer wall of the guide rod 207 fits against the outer wall of the cylindrical groove 202, which allows the support sleeve 201 to move along the outer wall of the guide rod 207 by relying on the cylindrical groove 202, thereby improving the movement stability of the support sleeve 201.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the support assembly 4 includes a connecting ring 401, which is fixedly connected to the outer wall of the support rod 5. A movable rod 402 is hinged to the outer wall of the connecting ring 401, and a connecting rod 403 is hinged to the outer wall of the movable rod 402. A movable ring 404 is hinged to one end of the connecting rod 403, and the movable ring 404 is threadedly connected to the outer wall of the threaded sleeve 3. A handle 405 is rotatably connected to the bottom of the support rod 5, and the bottom of the handle 405 is fixedly connected to the top of the threaded sleeve 3. The handle 405 can be turned to make the threaded sleeve 3 rotate on the inner wall of the movable ring 404, so that the movable ring 404 moves along the outer wall of the threaded sleeve 3. The movable ring 404 drives the connecting rod 403 to move, so that the connecting rod 403 drives the movable rod 402 to move. This allows the opening angle of the movable rod 402 to be adjusted so that its height is consistent with the height of the support sleeve 201, providing auxiliary support and improving the stability of the support.

[0021] Furthermore, such as Figure 4 As shown, the handle 405 forms a movable structure with the moving ring 404 via the threaded sleeve 3, and one end of the threaded sleeve 3 is fixedly connected to the bottom of the handle 405. The outer wall of the threaded sleeve 3 is threadedly connected to the inner wall of the moving ring 404. By turning the handle 405, the threaded sleeve 3 is driven to rotate on the inner wall of the moving ring 404, which allows the moving ring 404 to move along the outer wall of the threaded sleeve 3.

[0022] Furthermore, such as Figure 4As shown, the movable ring 404 forms a movable structure with the movable rod 402 via the connecting rod 403. One end of the connecting rod 403 is hinged to the outer wall of the movable ring 404, and the other end of the connecting rod 403 is hinged to the outer wall of the movable rod 402. When the movable ring 404 drives the connecting rod 403 to move, the connecting rod 403 drives the movable rod 402 to move.

[0023] Furthermore, such as Figure 4 As shown, the threaded sleeve 3 forms a movable structure with the connecting rod 403 via the movable ring 404. The inner wall of the movable ring 404 is threadedly connected to the outer wall of the threaded sleeve 3, and the outer wall of the movable ring 404 is hinged to one end of the connecting rod 403. This allows the movable ring 404 to push the connecting rod 403 to move when the threaded sleeve 3 moves the movable ring 404.

[0024] Working principle: When the guide bracket needs adjustment, the fixing sleeve 205 can be directly screwed on to disengage the internal thread 206 from the external thread 204, thus disengaging the fixing sleeve 205 from the support sleeve 201. At this time, the support sleeve 201 can be moved to a suitable height. Then, the fixing sleeve 205 is screwed on to press the fixing ring 203 to fix the support sleeve 201, completing the height adjustment. At the same time, the handle 405 can be screwed on to make the threaded sleeve 3 rotate on the inner wall of the moving ring 404, causing the moving ring 404 to move along the outer wall of the threaded sleeve 3. The moving ring 404 drives the connecting rod 403 to move, which in turn drives the moving rod 402 to move. The opening angle of the moving rod 402 can then be adjusted so that its height matches the height of the support sleeve 201, providing auxiliary support and improving support stability.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
