Description

Technical Field

[0001] This utility model relates to the technical field of hexagonal stud equipment, specifically a hexagonal stud structure. Background Technology

[0002] Hexagonal studs are a common type of mechanical fastener, named for their hexagonal heads. They are widely used in electronic equipment, machinery, and construction engineering. The hexagonal head makes it easy to install and remove using a wrench or socket, and can withstand large torques.

[0003] For example, the utility model patent disclosed in publication number CN207033933U discloses a hexagonal combination stud, including a nut and a screw rod. The nut and screw rod are directly integrated into a single structure. A fastening edge is formed on the outer side of the nut, and the fastening edge is respectively provided on the hexagonal shape of the nut. The fastening edge is also provided with a bonding piece, which is an elliptical planar shape. A cross screw thread is also provided on the outer side of the nut. A thread is provided on the outer surface of the screw rod, and a deformable silicone washer is provided on the inner side of the thread. The top of the screw rod coincides with the center of the nut, and the bottom of the screw rod is formed into an arc wedge shape. A combination washer is also fitted between the nut and the screw rod. The combination washer includes a break-type washer and a fully enclosed washer. An embedded washer is provided between the break-type washer and the fully enclosed washer and on the outer side of the fully enclosed washer, which improves the fastening effect and the applicability of the screw rod. The number and type of washer can be increased to meet the needs of different conditions, which improves the convenience of use.

[0004] Although the aforementioned hexagonal studs can be used to combine break washers, the hexagonal plate is prone to corrosion after prolonged use. Furthermore, if the corrosion is severe after installation, it is inconvenient to replace the hexagonal plate, thus requiring disassembly of the entire bolt and reducing the practical performance of the hexagonal bolt. Therefore, there is an urgent need for a hexagonal stud structure to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a hexagonal stud structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hexagonal stud structure, comprising a bolt housing for support, a hexagonal aligning groove formed at the center of the upper end face of the bolt housing, and a limiting groove formed at the center of the lower end face of the bolt housing.

[0007] Alignment bolts are slidably disposed on the inner end face of the limiting groove, and are used for limiting and docking.

[0008] A limiting device is slidably disposed on the inner end face of the bolt housing through the aligning hexagonal groove, and the limiting device is threadedly connected to the aligning bolt.

[0009] The tensioning device is fixedly installed at the bottom of the inner end face of the limiting device, and the tensioning device is used for anti-slip.

[0010] Preferably, the limiting device includes a bolt rotating plate, a limiting hexagonal slot is formed at the center of the upper end face of the bolt rotating plate, and a cross slot is formed at the bottom of the inner end face of the limiting hexagonal slot. An anti-corrosion outer layer is provided inside the limiting hexagonal slot and the cross slot. A hexagonal retaining shaft is fixedly provided at the center of the lower end face of the bolt rotating plate, and a threaded groove is formed at the center of the lower end face of the hexagonal retaining shaft. A limiting guide groove is formed on the outer side of the lower end face of the bolt rotating plate.

[0011] Preferably, the tensioning device includes an anti-slip pad, with six sets of spring guide shafts equidistantly arranged on the upper end surface of the anti-slip pad, and anti-slip protrusions equidistantly arranged on the lower end surface of the anti-slip pad.

[0012] Preferably, the hexagonal retaining shaft is slidably engaged with the inner end face of the bolt housing via the aligning hexagonal retaining groove. The sliding limit of the aligning hexagonal retaining groove and the hexagonal retaining shaft can provide sufficient radial limit foundation for the subsequent rotation of the bolt rotating plate, thereby improving the stability of the subsequent rotation of the bolt housing.

[0013] Preferably, the bottom of the hexagonal clasp is adapted to the alignment bolt through the threaded groove and then threadedly connected to the inner end face of the bolt housing. The threaded connection between the threaded groove and the alignment bolt can lock and limit the bolt rotating plate and the bolt housing. At the same time, after the alignment bolt and the threaded groove are threadedly connected, the bottom of the limiting groove can be sealed by wax injection or other gaskets to improve the service life of the alignment bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a limiting device, can effectively improve the shape integrity of the limiting hexagonal slot and cross slot through the anti-corrosion outer layer, thereby facilitating the subsequent disassembly of the bolt rotating plate and the bolt housing. At the same time, after the bolt rotating plate undergoes irreversible deformation, the alignment bolt can be connected to the threaded groove through the thread, thereby enabling the bolt rotating plate to be quickly and conveniently disassembled. This not only facilitates the disassembly and replacement of damaged bolt rotating plates by workers, but also facilitates the subsequent quick disassembly of the bolt housing and the external nut, thus improving the practical performance of the equipment.

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.

[0024] Please see Figure 1-5 One embodiment of this utility model provides a hexagonal stud structure, including a bolt housing 1 for support, a hexagonal groove 5 for alignment at the center of the upper end face of the bolt housing 1, and a limiting groove 6 at the center of the lower end face of the bolt housing 1.

[0025] Alignment bolt 4 is slidably disposed on the inner end face of the limiting groove 6. Alignment bolt 4 is used for limiting and docking.

[0026] The limiting device 2 is slidably disposed on the inner end face of the bolt housing 1 through the alignment hexagonal groove 5, and the limiting device 2 is threadedly connected to the alignment bolt 4.

[0027] Tensioning device 3 is fixedly installed at the bottom of the inner end face of limiting device 2, and is used for anti-slip.

[0028] The limiting device 2 includes a bolt rotating plate 23. A limiting hexagonal slot 21 is formed at the center of the upper end face of the bolt rotating plate 23, and a cross slot 24 is formed at the bottom of the inner end face of the limiting hexagonal slot 21. An anti-corrosion outer layer 22 is provided inside the limiting hexagonal slot 21 and the cross slot 24. A hexagonal retaining shaft 25 is fixedly provided at the center of the lower end face of the bolt rotating plate 23, and a threaded groove 26 is formed at the center of the lower end face of the hexagonal retaining shaft 25. A limiting guide groove 27 is formed on the outer side of the lower end face of the bolt rotating plate 23.

[0029] The tensioning device 3 includes an anti-slip pad 32, with six sets of spring guide shafts 31 equidistantly arranged on the upper end surface of the anti-slip pad 32, and anti-slip protrusions 33 equidistantly arranged on the lower end surface of the anti-slip pad 32.

[0030] The hexagonal retaining shaft 25 is slidably engaged with the inner end face of the bolt housing 1 by aligning with the hexagonal retaining groove 5. The sliding limit of the aligning hexagonal retaining groove 5 and the hexagonal retaining shaft 25 can provide sufficient radial limit foundation for the subsequent rotation of the bolt rotating plate 23, thereby improving the stability of the subsequent rotation of the bolt housing 1.

[0031] The bottom of the hexagonal clasp 25 is adapted to the alignment bolt 4 through the threaded groove 26 and then threadedly connected to the inner end face of the bolt housing 1. The threaded connection between the threaded groove 26 and the alignment bolt 4 can lock and limit the bolt rotating plate 23 and the bolt housing 1. At the same time, after the alignment bolt 4 and the threaded groove 26 are threadedly connected, the bottom of the limiting slide 6 can be sealed by wax injection or other gaskets to improve the service life of the alignment bolt 4.

[0032] The anti-slip pad 32 is slidably disposed on the inner end face of the limiting guide groove 27. The limiting guide groove 27 can provide sufficient guiding foundation for the anti-slip pad 32, improve the stability of the anti-slip pad 32 when pressed onto the outside of the workpiece, and also improve the anti-slip performance.

[0033] Working principle: When using this device, if it is necessary to lock automotive parts or other workpieces, the operator can position the bolt housing 1 and the limiting device 2 inside the workpiece, and then align the bottom bolt housing 1 with the nut to complete the locking. After prolonged use, if it is necessary to limit the contact of the workpiece, the operator can insert the tool into the limiting hexagonal slot 21 for limiting, and then rotate it to separate the bolt housing 1 from the outer nut. The anti-corrosion outer layer 22 can protect the shape of the limiting hexagonal slot 21 and cross slot 24 inside the bolt rotating plate 23, improving the stability of the tool's limiting. If the anti-corrosion outer layer 22 is corroded, or the shape of the limiting hexagonal slot 21 and cross slot 24 cannot be restored, the operator can insert the tool into the limiting slide 6, and then rotate the alignment bolt 4 to separate the alignment bolt 4 from the hexagonal clasp 25, thereby releasing the limiting of the bolt rotating plate 23. Then, the operator can align a new set of bolt rotating plates 23 through the alignment bolt 4, and then separate the bolt housing 1 from the nut.
