Description

Technical Field

[0001] The utility model relates to the technical field of hexagon socket head cap screws, in particular to a reliable fastening hexagon socket head automotive bolt. Background Art

[0002] The hexagon socket head automotive bolt is a commonly used fastener and plays an important role in automobile manufacturing and maintenance. The hexagon socket head automotive bolt mainly consists of three parts: a head, a thread, and a screw rod. The head is designed with a hexagonal notch, the thread part is used to cooperate with a nut or other threaded holes, and the screw rod is the main part for connection and fastening.

[0003] After retrieval, the patent with the publication number CN200920081876.8 discloses a hexagon socket head cap screw. Although the device is made by subjecting the lead screw, nut, hexagon socket, and opening to high-temperature calcination and then stamping with a stamping machine, and a lead screw is made on the bolt with a tapping machine, and the lead screw, nut, hexagon socket, and opening are made into an integral body. It is mainly used to facilitate the user to use the bolt. However, although the device has been processed by a special process during use, in actual use, if the pre-tightening force is set insufficiently, or due to factors such as materials and processes, the pre-tightening force is unevenly distributed, then when subjected to mechanical vibration, the friction force between the bolt and the nut will decrease, resulting in loosening. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a reliable fastening hexagon socket head automotive bolt, which solves the problems raised in the background art.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] A reliable fastening hexagon socket head automotive bolt, including a bolt, an inner hexagon groove is opened on the bolt, a slotted screw drive is opened at the position of the inner hexagon groove on the bolt, and a screw rod is provided on the bolt;

[0007] A first through hole is penetrated through the screw rod, a locking block is installed on the screw rod of the bolt, the locking block includes a hoop and a fixing plate, internal threads are opened on the inner sides of the hoop and the fixing plate, a second through hole is penetrated through the fixing plate, and the locking block is locked and fixed on the screw rod through the second through hole of the fixing plate and a rivet rod.

[0008] Based on the above technical solutions, the utility model can be further improved as follows.

[0009] Further, the locking block is clamped and connected with the screw rod through the internal threads in the hoop and the fixing plate, and is limited and installed on the screw rod.

[0010] The beneficial effect of adopting the above further solution is:

[0011] The tight clamping between the locking block and the screw ensures the stability of the connection. Even in the case of mechanical vibration or impact, this design can effectively prevent the relative movement between the screw and the nut, thus maintaining the tightened state of the connection. In applications that require high-strength fastening, such as in automobile manufacturing and repair, this design can significantly reduce the safety hazards caused by loosening of the connection. It ensures the stable connection of key components and prevents failures or accidents caused by loosening. The design of the locking block makes the installation process simpler and faster. At the same time, due to its self-locking function, the workload of frequent inspection and tightening due to loosening is also reduced during daily maintenance.

[0012] Furthermore, the positions and sizes of the first through hole and the second through hole are adapted to each other, and after the locking block and the screw are spliced, they are locked and fixed by a rivet rod.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The positions and sizes of the first through hole and the second through hole are adapted to each other, ensuring the precise docking between the locking block and the screw. This precise docking provides a solid foundation for the subsequent locking operation, making the entire connection structure more stable and reliable. By passing the rivet rod through these two through holes for locking and fixing, the strength and stability of the connection are further enhanced. The locking method of the rivet rod can effectively prevent the loosening of the locking block under vibration or impact, ensuring the long-term stability of the connection. Since the positions and sizes of the first through hole and the second through hole have been pre-designed and adapted to each other, the docking and locking of the locking block and the screw can be quickly completed during the installation process. This greatly simplifies the installation steps and improves the installation efficiency. At the same time, the locking method of the rivet rod is also relatively simple and fast, without the need for complex tools or operation skills, further accelerating the installation speed.

[0015] Furthermore, after the first through hole of the bolt passes through the component to be fixed, the locking block cooperates with the bolt from the other side of the component to be fixed to clamp and fix the component to be fixed or the nut installed on the component to be fixed and the screw.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] During the installation process, the bolt first passes through the part to be fixed, and then the locking block cooperates with the bolt or the nut on the bolt from the other side to clamp and fix it. This sequential installation step makes the installation process clearer and simpler, reducing the installation difficulty and error rate. This design enables the locking block to directly act on the part to be fixed or on the part to be fixed and the nut, enhancing the connection strength through the clamping and fixing method. Compared with relying only on the threaded connection between the bolt and the nut, this design provides additional fastening force, making the connection more stable and reliable. The locking block cooperates with the bolt from the other side of the part to be fixed, forming a double lock on the connection point. This design effectively prevents the connection from loosening due to factors such as vibration, impact, or temperature change, improving the connection stability.

[0018] Furthermore, the flat slot and the hexagon socket are coaxial.

[0019] The beneficial effect of adopting the above further scheme is:

[0020] The design that the flat slot and the hexagon socket are coaxial allows users to choose a suitable tool for operation according to the actual situation. In the absence of a hexagon wrench, a flat-blade screwdriver can be used to tighten or disassemble through the flat slot, improving the operation flexibility. The design of the hexagon socket allows the use of a hexagon wrench to apply a greater torque, thus ensuring that the fastener can be fixed more firmly. Although the torque transmission ability of the flat slot may be slightly inferior to that of the hexagon socket, it can also meet the fastening requirements in some cases. The coaxial design of the two ensures that no matter which tool is used, it can effectively act on the fastener, enhancing the fastening effect.

[0021] The utility model provides a hexagon automotive bolt with reliable fastening. It has the following beneficial effects:

[0022] Both a hexagon socket and a flat slot are designed on the bolt, and the two are coaxial. This design allows users to flexibly choose to use a hexagon wrench or a flat-blade screwdriver for fastening according to the actual situation or the available tools at hand, improving the convenience and flexibility of use.

[0023] By introducing the locking block, especially the design of its hoop and fixing plate, and the tight clamping of the two through the internal thread and the screw rod, double fastening of the bolt and the nut (if installed) is achieved. This design significantly improves the connection stability and reliability, reducing the risk of loosening or falling off.

[0024] After the locking block is spliced with the screw rod, it is locked and fixed by a rivet rod. This locking method is not only simple and easy to implement, but also firm and reliable, ensuring that the connecting piece remains fastened under harsh working conditions such as vibration or impact.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Please refer to Figures 1 to 4 as shown, the embodiments provided by the present utility model:

[0035] Embodiment 1: A hex socket head automotive bolt with reliable fastening, comprising a bolt 1. An internal hexagon socket 104 is provided on the bolt 1. A slotted screwdriver slot 103 is provided at the position of the internal hexagon socket 104 on the bolt 1. The slotted screwdriver slot 103 and the internal hexagon socket 104 are coaxial. The coaxial design of the slotted screwdriver slot 103 and the internal hexagon socket 104 maximizes the flexibility of tool selection. In the absence of a hex key, the user can complete the fastening or disassembly operation through the slotted screwdriver slot 103 with the help of a slotted screwdriver, improving the operation flexibility. The internal hexagon socket 104 is designed specifically for high torque transmission to ensure that the fastener can be firmly fixed. As an alternative, the slotted screwdriver slot 103 has slightly lower torque transmission capacity, but can still meet the fastening requirements in specific situations. The coaxial design of the two ensures that no matter which tool is selected, it can effectively act on the fastener, strengthening the fastening effect. A screw rod 101 is provided on the bolt 1.

[0036] Embodiment 2: To prevent the bolt 1 from loosening after being fixed, exemplarily, such as Figures 1 to 4As shown, the present invention further includes: a first through-hole 102 is formed through the screw rod 101. After the first through-hole 102 of the bolt 1 passes through the component to be fixed, the locking block 2 cooperates with the bolt 1 from the other side of the component to be fixed to clamp and fix the component to be fixed or the nut installed on the component to be fixed and the screw rod 101. During the installation process, the bolt 1 first accurately penetrates the component to be fixed, and then the locking block 2 acts in cooperation with the bolt 1 or the nut thereon from the other side to implement clamping and fixing. This sequential installation process improves the clarity and convenience of the installation process, reduces the installation difficulty and error rate. This design endows the locking block 2 with the ability to directly act on the component to be fixed or the combination of it and the nut, and significantly enhances the connection strength through the clamping and fixing method. Compared with the method that solely relies on the threaded connection between the bolt 1 and the nut, this design provides additional fastening force to ensure the firm and reliable connection. The mutual cooperation between the locking block 2 and the bolt 1 forms a double locking mechanism for the connection point on the other side of the component to be fixed, effectively resisting the influence of factors such as vibration, impact, and temperature change on the connection stability. A locking block 2 is installed on the screw rod 101 of the bolt 1. The locking block 2 includes a hoop 201 and a fixing plate 202. Internal threads 203 are provided on the inner sides of the hoop 201 and the fixing plate 202. The locking block 2 is clamped and connected to the screw rod 101 through the internal threads 203 in the hoop 201 and the fixing plate 202 and is limitedly installed on the screw rod 101, thereby preventing the end of the screw rod 101 and the nut installed thereon from moving randomly. The precise clamping mechanism between the locking block 2 and the screw rod 101 ensures the stability of the connection. Even in a harsh environment subjected to mechanical vibration or impact, this design can effectively restrain the relative displacement between the screw rod 101 and the nut and maintain the tightened state of the connection. In scenarios with high-strength fastening requirements such as automobile manufacturing and maintenance, this design significantly reduces the safety hazards caused by connection loosening, ensures the firm connection of key components, and effectively prevents failures or accidents induced by loosening. In addition, the ingenious design of the locking block 2 simplifies the installation process, and its built-in self-locking function greatly reduces the amount of inspection and tightening operations that need to be frequently carried out due to loosening during daily maintenance. A second through-hole 205 is formed through the fixing plate 202. The positions and sizes of the first through-hole 102 and the second through-hole 205 are adapted to each other, and after the locking block 2 and the screw rod 101 are spliced, they are locked and fixed by a rivet rod 204. The precise adaptation of the first through-hole 102 and the second through-hole 205 in terms of position and size lays a solid foundation for the seamless docking between the locking block 2 and the screw rod 101. This precise docking provides strong support for the subsequent locking operation and enhances the overall stability and reliability of the connection structure. The locking and fixing achieved by passing the rivet rod 204 through the two through-holes further improves the strength and stability of the connection. The locking mechanism of the rivet rod 204 effectively resists the influence of vibration and impact on the stability of the locking block 2 and ensures the long-term stability of the connection. The preset through-hole adaptability simplifies the installation process, and the simplicity of the locking by the rivet rod 204 does not require complex tools or skills, accelerating the installation efficiency.

[0037] Working principle:

[0038] The hexagon socket 104 opened on the bolt 1 allows the use of a hexagon wrench for fastening. This is a standard fastening method that provides a large torque transmission capacity and ensures the initial fastening of the bolt 1. At the same time, a slotted screwdriver slot 103 is also opened on the bolt 1. This slot is coaxial with the hexagon socket 104 and serves as a backup fastening method. In the absence of a hexagon wrench, a slotted screwdriver can be used for fastening, improving the flexibility of use.

[0039] The locking block 2 is composed of a hoop 201 and a fixing plate 202. Internal threads 203 are opened on the inner sides of both. These internal threads 203 match the external threads on the screw rod 101 of the bolt 1, enabling the locking block 2 to be tightly clamped on the screw rod 101. After the bolt 1 passes through the workpiece to be fixed, the locking block 2 cooperates with the bolt 1 from the other side of the workpiece to be fixed, thus achieving double fastening of the bolt 1 and the nut (if installed).

[0040] After the locking block 2 and the screw rod 101 are spliced, a riveting rod 204 is used to pass through the second through hole 205 on the fixing plate 202 and the first through hole 102 on the screw rod 101 for locking and fixing. This locking method further enhances the stability of the connection and prevents the locking block 2 from loosening under vibration or impact.
