Description

Technical Field

[0001] This utility model relates to the field of hexagonal bolt technology, specifically a hexagonal bolt connector for exterior wall panels. Background Technology

[0002] In the installation of building exterior wall panels, bolted connectors are key components for achieving fixed connections between wall panels and the wall or between wall panels. Currently, most bolts used for connecting exterior wall panels in existing technologies are of traditional structure, which mainly rely on the thread of the bolt body to cooperate with pre-drilled holes or nuts to achieve fixation.

[0003] However, these traditional bolts have a limited function, only providing fixation when pre-drilled holes are present in the wall panel. When encountering exterior wall panels without pre-drilled holes, construction workers must use additional tools such as electric drills to drill holes in the wall panel, increasing construction steps and time costs. Furthermore, improper operation during the drilling process may cause cracking or damage to the wall panel, affecting the construction quality.

[0004] In addition, the traditional bolt fixing method lacks flexibility. Once the hole position deviates or the wall panel specifications change, the existing bolts are difficult to adapt and adjust. Different specifications of connectors need to be replaced or secondary processing is required, which limits its application in complex construction scenarios. Its adaptability and practicality are both obviously insufficient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hexagonal bolt connector for exterior wall panels.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hexagonal bolt connector for exterior wall panels includes: a hexagonal nut, a bolt on the hexagonal nut, a limiting ring fixedly mounted on the bolt, a threaded groove on the right side of the limiting ring, a groove 1 on the top of the bolt and the right side of the limiting ring, a groove 2 on the top of the bolt and the left side of the limiting ring, groove 1 and groove 2 communicating through the limiting ring, a circular through hole near the center of the bolt in groove 1 and groove 2, and a screw assembly mounted on the circular through hole near the center of the bolt in groove 1 and groove 2.

[0008] The screw assembly includes: a screw, a limiting block, a support post at the bottom of the limiting block, and guide sleeve block one and guide sleeve block two on the support post. Guide sleeve block one and guide sleeve block two are clearance-fitted with the inner circular through hole of the bolt. Guide sleeve block one and guide sleeve block two are used to move the screw assembly along groove one and groove two when the limiting block drives it. The screw assembly is used to set a movable screw in the bolt.

[0009] Preferably, a large through hole and a small through hole are sequentially provided through the bottom of the support column and the guide sleeve. A sliding rod is provided in the small through hole. A fixed column is provided at the bottom of the sliding rod. A spring is arranged around the fixed column. A circular base plate is fixedly provided at the bottom of the fixed column. An elastic sleeve is also fixedly provided on the circular base plate. The elastic sleeve is in sliding clearance fit with the inner wall of the large through hole. One end of the spring is connected to the top of the large through hole, and the other end of the spring is fixedly connected to the surface of the circular base plate.

[0010] Preferably, a through hole 2 for a through bolt is provided below the first groove, and a through hole 3 for a through bolt is provided on the rear side of the second groove. The through holes 2 and 3 are used to restrict the movement of the screw assembly by having the spring compress the elastic sleeve through the through holes 2 or 3 when the screw assembly moves to the position of the through holes 2 or 3.

[0011] Preferably, a slide bar 2 is provided through the top of the nut. The slide bar 2 is detachable. When the spring compresses the elastic sleeve through the through hole 2 or through hole 3, the slide bar 2 is used to push into the through hole 2 or through hole 3, and at the same time, the limiting block is moved to release the locking state.

[0012] Compared with the prior art, this utility model provides a hexagonal bolt connector for exterior wall panels, which has the following advantages:

[0013] The screw assembly can move within the bolt via grooves one and two, achieving precise positioning through the clearance fit between guide sleeve one and guide sleeve two. When dealing with exterior wall panels without pre-set holes, no external tools such as electric drills are needed; fixing can be completed directly by moving the screw assembly, simplifying the construction process and reducing the need to carry tools.

[0014] The movable design of the screw assembly allows it to adjust the fixing position according to the actual structure of the exterior wall panel. Whether it is a pre-set hole deviation or a wall panel without holes, the screw assembly can be moved to the appropriate position along the groove by adjusting the limit block. Then, the spring squeezes the elastic sleeve through the through hole two or through hole three to achieve locking. This effectively adapts to exterior wall panels of different specifications and structures, improving the scene adaptability of the connector. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Reference Figures 1-8 As shown, this embodiment of a hexagonal bolt connector for exterior wall panels includes a hexagonal nut 1, which is fixedly connected to a bolt 2 to form the main support structure of the connector. A limiting ring 204 fixedly installed on the bolt 2 serves to separate the left and right sections of the bolt 2, and the thread 202 surrounding the right side of the bolt 2 is used to cooperate with the preset hole position of the exterior wall panel to achieve initial fixation.

[0026] The top of bolt 2 communicates with the right side groove 203 and the left side groove 205 of the limiting ring 204, providing a moving channel for screw assembly 3. Grooves 203 and 205 are close to the circular through hole 201 in the center of bolt 2, which are used to accommodate guide sleeve 304 and guide sleeve 305 of screw assembly 3, ensuring that screw assembly 3 moves smoothly along the grooves.

[0027] The limiting block 302 in the screw assembly 3 is fixedly connected to the support column 303. The guide sleeve 1 304 and guide sleeve 2 305 on the support column 303 are in clearance fit with the circular through hole 201. When the limiting block 302 is subjected to force, it can drive the entire screw assembly 3 to slide along the groove 1 203 and the groove 2 205 to realize the position adjustment of the screw 301.

[0028] In some examples, the cooperation structure between the slide rod 311 and the fixed post 310 within the large and small through holes at the bottom of the support post 303 and the guide sleeve 304 provides guidance for the extension and retraction of the elastic sleeve 309. The elastic force of the spring 308 causes the circular base plate 307 to drive the elastic sleeve 309 to always have an outward expansion tendency. When the screw assembly 3 moves to the position of through hole 2 or through hole 3 206, the elastic sleeve 309 can quickly pop out and pass through the through hole, realizing the automatic locking of the screw assembly 3 and improving the connection stability.

[0029] In some examples, the through hole 2 below the groove 203 and the through hole 3 206 behind the groove 205 are symmetrically distributed on both sides of the bolt 2. Different through holes can be selected for locking according to the thickness of the outer wall panel. When the wall panel is thin, the screw assembly 3 moves to the position of through hole 2 for locking; when the wall panel is thick, it moves to the position of through hole 3 206 for locking, enhancing the sizing compatibility of the connector.

[0030] In some examples, the removable slide bar 2 at the top of nut 1 is made of high-strength alloy material, and its diameter matches that of through holes 2 and 3 206. When it is necessary to adjust the position of screw assembly 3, slide bar 2 is inserted into the through hole and the elastic sleeve 309 is pressed to compress the spring 308 and release it from the lock. This operation is effortless, not easily deformed, and extends the tool's service life.

[0031] In some examples, the outer surfaces of guide sleeve 1 304 and guide sleeve 2 305 are provided with a wear-resistant coating. This coating can reduce the coefficient of friction between the guide sleeve and the inner wall of the circular through hole 201, reduce wear during movement, make the adjustment of the screw assembly 3 smoother, and extend the overall service life of the connector.

[0032] In some examples, the elastic sleeve 309 is made of rubber and has annular protrusions on its outer wall. The protrusions enhance the friction between the elastic sleeve 309 and the inner walls of the through holes 2 and 3 206, preventing loosening due to vibration after locking and ensuring the long-term stability of the outer wall panel connection.

[0033] The working principle of this utility model is as follows:

[0034] When using this type of hexagonal bolt connector for exterior wall panels, first determine the connection position according to the installation requirements of the exterior wall panel, and align the threaded end 202 of bolt 2 with the installation reference surface. Utilizing the hexagonal structure of the hexagonal nut 1, rotate the hexagonal nut 1 with a wrench or other tools to make the thread 202 on the right side of bolt 2 engage with the preset installation hole. The limiting ring 204 fits against the surface of the wall panel, and the tightening force of the threaded connection achieves the initial fixation of the connector to the wall panel, ensuring the stability of the overall structure.

[0035] When dealing with exterior wall panels without pre-drilled holes, no additional drilling is required; the screw assembly 3 can be directly operated for fixing. At this time, remove the detachable sliding rod two from the top of the nut 1, align it with the through hole three 206, and insert it, pushing the elastic sleeve 309 into the through hole three 206. Due to the sliding clearance fit between the elastic sleeve 309 and the large through hole of the support column 303, the spring 308 will be compressed under pressure, causing the circular base plate 307 and the fixing column 310 to move upwards, disengaging the elastic sleeve 309 from the through hole three 206 and releasing the locking state of the screw assembly 3. Simultaneously, push the limiting block 302. Under the clearance fit between the guide sleeve one 304 and the guide sleeve two 305 and the circular through hole 201, the support column 303 will move along the groove two 205 and the groove one 203 until the screw 301 reaches a position that can break through the wall panel. At this time, the rebound force of the spring 308 pushes the circular base plate 307 down, so that the elastic sleeve 309 passes through the through hole 2, re-locks the screw assembly 3, and fixes it by pushing the screw 301 into the wall panel, eliminating the drilling step.

[0036] If the exterior wall panel has preset holes but the positions are off, a similar operation can be used to adjust the position of the screw assembly 3. First, use the slide bar 2 to release the current lock, then move the screw assembly 3 along the groove 1 203 or the groove 2 205 to the position corresponding to the off-center hole. Use the guide sleeve to ensure that the screw 301 is aligned with the hole, and then lock it with the elastic sleeve 309. Together with the thread 202 of the bolt 2, a stable connection is achieved, improving the adaptability to hole position deviations.

[0037] When it is necessary to disassemble or adjust the position of the connector, use the slide bar to press the elastic sleeve 309 in the corresponding through hole again, the compression spring 308 is released from locking, the moving limit block 302 resets the screw assembly 3 to the initial position, and then rotate the hexagonal nut 1 in the opposite direction to disengage the thread 202 from the mounting hole, thus completing the disassembly.

[0038] This connector adopts a modular design. The components of the screw assembly 3 are combined through nesting or fixed connections, and can be removed individually for cleaning and maintenance. Furthermore, key components such as the threads 202 of bolt 2 are treated with anti-corrosion coating, and the guide sleeve has a wear-resistant coating, ensuring good performance during long-term use, adapting to complex environments such as damp exterior walls, and extending service life.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
