Technical Field

[0001] This utility model belongs to the field of single-rod connection box technology, specifically a single-rod connection box structure with retractable spacing. Background Technology

[0002] Traditional single-pole connector box structures typically have fixed spacing, making them difficult to adjust flexibly to different installation spaces and layout requirements. In scenarios with limited space or complex layouts, fixed-spacing connector structures may not meet installation needs, requiring additional modifications or customization, which increases costs and construction complexity.

[0003] Meanwhile, a box-type connecting column and composite beam steel box docking connection structure with announcement number CN219157933U is disclosed, including: upper precast column, lower precast column and precast composite beam, wherein the lower end of the upper precast column is precast with a connecting box C, and the lower precast column is precast with a high-strength bolt rod.

[0004] The aforementioned box-type connecting column and composite beam steel box butt connection structure can only have good seismic performance and post-earthquake repair capability, but it cannot fix the connection structure after connection. This may lead to the risk of the connection structure shaking due to external factors, slowly falling off and displacing during use.

[0005] Therefore, a single-rod connector box connection structure with expandable spacing is proposed to address the above problems. Utility Model Content

[0010] Preferably, a spring layer is fixedly provided on the upper end surface of the fixing plate, and a column groove is provided inside the spring layer, with bolts inserted through the spring layer.

[0011] By adopting the above technical solution, the spring-loaded layer can provide a certain buffer and rebound function when the component is subjected to external force, reducing rigid collisions and impacts. The bolts are inserted into the spring-loaded layer, so that when connecting other components, the spring-loaded layer can play a protective and buffering role, while also ensuring the continuity of the bolt installation structure.

[0012] Preferably, a hexagonal cap is fixedly provided on the upper end face of the bolt, and the hexagonal cap is attached to the upper side of the spring-loaded layer.

[0013] By adopting the above technical solution, the hexagonal cap is attached to the upper side of the spring layer, which can limit the axial movement of the bolt to a certain extent and ensure the stability of the bolt during use.

[0014] Preferably, a steel bar is fixedly provided in the middle of the upper end face of the single rod connecting box body, and fixed long bodies are fixedly provided on both the left and right sides of the lower end face of the single rod connecting box body.

[0016] Preferably, a support plate is fixedly provided on the inner side of the fixed elongated body, and a column groove is formed inside the support plate.

[0017] By adopting the above technical solution, the support plate can provide additional support and reinforcement for the fixed long body, enhance the structural stability of the fixed long body, and the opening of the column groove provides an installation position for the hollow threaded sleeve, which is convenient for connection with other components with matching structures.

[0018] Preferably, the inner surface of the layer plate is provided with a second threaded groove, and the bolt rotates inside the second threaded groove.

[0019] By adopting the above technical solution, the threaded groove two on the shelf cooperates with the bolt. By rotating the bolt in the threaded groove two, the connection and fixation between the shelf and the bolted component can be realized, so that the shelf can be firmly installed in the corresponding position.

[0020] Preferably, a hollow threaded sleeve is fixedly provided inside the support plate, and a threaded groove is opened in the middle of the lower end of the single rod connecting box body, and the bolt rotates inside the threaded groove.

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.

[0031] The following describes an embodiment of this utility model based on its overall structure.

[0032] like Figures 1 to 4 As shown, this utility model provides a single-rod connecting box connection structure with retractable spacing. It includes a single-rod connecting box body 1 with a shelf 6 fixed inside for fixing. The upper end face of the shelf 6 is fixed with telescopic blocks 13 on both the left and right sides for telescopic fixing. The upper end of the telescopic blocks 13 is slidably provided with a telescopic block 12. The upper end face of the telescopic block 12 is fixed with a fixing plate 11. The lower end face of the fixing plate 11 is fixed with a washer 14 in the middle. The lower end face of the washer 14 is fitted with a nut 15 for tightening and fixing.

[0033] The fixed plate 11 has a column groove 17 inside, and the column groove 17 is equipped with a bolt 4 for adjustment.

[0034] The upper end face of the fixing plate 11 is fixed with a spring layer 10 to play a role in spring-loaded fixing. The spring layer 10 has a column groove 17 inside, and the bolt 4 passes through the spring layer 10.

[0035] A hexagonal cap 18 is fixed on the upper end face of the bolt 4 for fixing, and the hexagonal cap 18 is attached to the upper side of the spring layer 10.

[0036] A steel bar 2 is fixedly installed in the middle of the upper end face of the single rod connecting box body 1 for fixing, and a fixed long body 5 is fixedly installed on both the left and right sides of the lower end face of the single rod connecting box body 1.

[0037] A support plate 8 is fixedly provided on the inner side of the fixed long body 5 to play a fixing role, and a column groove 9 is opened inside the support plate 8.

[0038] The inner part of the shelf 6 has a threaded groove 16, and the bolt 4 rotates inside the threaded groove 16.

[0039] The support plate 8 is internally fixed with a hollow threaded sleeve 3 for internal adjustment. The lower end of the single rod connecting box body 1 is provided with a threaded groove 7, and the bolt 4 rotates inside the threaded groove 7.

[0040] Working principle and process of the retractable spacing single-pole connector box connection structure:

[0041] The retractable single-rod connecting box connection structure mainly utilizes telescopic block 12, telescopic block 23, fixing plate 11, and nut 15 to fix the connection structure. Simultaneously, the spacing between relevant components of the single-rod connecting box body 1 is adjusted using bolts 4 and hollow threaded sleeves 3 to adapt to different usage scenarios and installation requirements. Telescopic block 23 is fixed to the left and right sides of the upper end face of the shelf 6. Telescopic block 12 can slide inside the upper end of telescopic block 23. By adjusting the position of telescopic block 12 within telescopic block 23, different installation height requirements can be accommodated. Once the position of telescopic block 12 is determined, it and telescopic block 213 together form a stable support structure, providing solid support for the fixing plate 11 above. To ensure the vertical stability of the entire connection structure, the fixing plate 11 is fixed to the upper end face of the telescopic block 12. The washer 14 in the middle of its lower end face and the fitted nut 15 work together to achieve fastening. The washer 14 can increase the contact area, distribute pressure, and prevent the nut 15 from directly contacting the lower part and damaging the surface of the part. At the same time, it can also prevent the nut 15 from loosening. The nut 15, through tightening action, tightly connects the fixing plate 11 and the lower part together, ensuring the horizontal stability of the connection structure. The bolt 4 passes through the column groove 17 of the spring-loaded layer 10, the column groove 17 of the fixing plate 11, and then enters the threaded groove 16 of the layer plate 6, the hollow threaded sleeve 3 in the support plate 8, and the single rod connecting box. The threaded groove 7 at the lower center of the inner part of body 1 allows for axial displacement of bolt 4 during rotation of the hexagonal cap 18 at the upper end of bolt 4 due to the threaded engagement between bolt 4 and threaded grooves 7, 16, and the hollow threaded sleeve 3. The hollow threaded sleeve 3, fixed inside the support plate 8, provides precise guidance for the rotation of bolt 4. During bolt 4 rotation, the hollow threaded sleeve 3 ensures that bolt 4 moves in the correct direction, preventing deviation or wobbling. This allows relative displacement between components to occur in a predetermined manner, achieving smooth and accurate adjustment of the connection structure spacing. Using a suitable wrench to rotate the hexagonal cap 18 at the upper end of bolt 4, rotating bolt 4 clockwise... Bolt 4 will move downwards within threaded groove 7, threaded groove 16, and hollow threaded sleeve 3, thereby reducing the distance between the components. When bolt 4 is rotated counterclockwise, it will move upwards, increasing the distance between the components. During adjustment, bolt 4 should be rotated slowly according to actual needs, and the changes in distance should be observed at any time. When the distance of the connection structure is adjusted to meet the design requirements or actual usage needs, stop rotating bolt 4 and check again whether the connection between the components is tight and whether the distance is accurate. If a distance deviation is found, bolt 4 can be fine-tuned until a satisfactory effect is achieved. The aforementioned fixed long body 5, support plate 8, hollow threaded sleeve 3, and steel bar 2 are all embedded inside the wall for fixation.
