Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a torque-shear bolt that is easy to disassemble. Background Technology

[0002] Torque-shear bolts are widely used in the connection of industrial and civil buildings, bridges, tower and mast structures, lifting machinery and other steel structures. During installation, a special wrench is used to hold the spline head at the end of the nut and tighten it. The installation is considered qualified when the spline head breaks off.

[0003] After installation, the spline head of a torque-shear bolt is broken off. If disassembly is required, the nut must be tightened. Since the bolt head cannot be fixed, disassembly is very difficult. Therefore, a torque-shear bolt that is easy to disassemble is needed to solve this problem. Utility Model Content

[0008] Furthermore, an improvement of this utility model is that the stopper is made of rubber and has multiple cavities.

[0009] Furthermore, the present invention includes the following improvements: the bolt head is provided with a plurality of protrusions on its periphery, the plurality of protrusions are of the same size, and the two ends of the protrusions are provided with bevels; the protrusions and the bolt head are integrally formed.

[0010] (III) Beneficial Effects

[0011] Compared with the prior art, this utility model provides a torque-shear bolt that is easy to disassemble, and has the following beneficial effects:

[0012] The top of the bolt head has two regular hexagonal grooves (the first groove and the second groove). The first groove has a removable rubber plug. When disassembly is required, simply remove the plug from the first groove, and then insert the corresponding tool (such as an Allen wrench) into the first or second groove. This provides additional operating space and torque application points for disassembly, increasing the convenience of disassembly and the diversity of operating methods.

[0013] When stripping occurs at the first groove, the bolt head can be operated through the second groove, which further facilitates the disassembly of this structure. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-3 This utility model discloses a conveniently disassembled torsion shear bolt, comprising a bolt head 1, a screw 2 at the lower end of the bolt head 1, a Torx head 3 at the bottom end of the screw 2, a nut 4 penetrating the bolt head 1 below the screw 2, and the nut 4 being threadedly connected to the screw 2. A first groove 6 is provided at the top of the bolt head 1, and a second groove 7 is provided at the bottom of the first groove 6. Both the first groove 6 and the second groove 7 have a regular hexagonal cross-section. A removable plug 8 is provided inside the first groove 6.

[0020] The plug 8 is made of rubber and has multiple cavities 9.

[0021] The bolt head 1 has a plurality of protrusions 5 on its periphery. The plurality of protrusions 5 are the same size and the two ends of the protrusions 5 are provided with bevels. An improvement of this utility model is that the protrusions 5 and the bolt head 1 are an integral structure.

[0022] Component manufacturing and preparation:

[0023] Manufacturing bolt head 1: Bolt head 1 is a one-piece molded component with multiple integral protrusions 5 on its periphery. The protrusions 5 are all the same size and have beveled ends, and can be manufactured by processes such as casting or forging.

[0024] A first groove 6 is machined on the top of the bolt head 1. The cross-section of the first groove 6 is a regular hexagon, and its depth is determined according to the design requirements.

[0025] A second groove 7 is further machined at the bottom of the first groove 6. The cross-section of the second groove 7 is also a regular hexagon. Its depth and size are determined according to the design requirements to ensure the installation and function of the subsequent plug 8.

[0026] Manufacturing screw 2: The upper end of screw 2 is connected to bolt head 1, and the lower end is provided with a sprite head 3. Screw 2 can be manufactured by turning, thread rolling and other processes to ensure the accuracy and strength of its threaded part and meet the required connection and force requirements.

[0027] Manufacturing nut 4: The size of nut 4 matches that of screw 2, and it is threaded onto screw 2. Nut 4 can be manufactured by forging or casting, and the internal threads are formed by tapping or thread rolling.

[0028] Manufacturing the stopper 8: The stopper 8 is made of rubber material and is molded according to the size of the first groove 6 to ensure that it can be tightly embedded in the first groove 6. Multiple cavities 9 are provided on the stopper 8. These cavities 9 can be directly formed by the mold during molding or obtained by secondary processing after molding to achieve effects such as weight reduction and increased elasticity.

[0029] The upper end of the screw 2 is connected to the bolt head 1. A strong connection method such as welding, riveting or integral molding can be used to ensure the reliability of the connection between the two.

[0030] Place the nut 4 onto the screw 2, and rotate the nut 4 to make it threadedly connected to the screw 2, ensuring that the nut 4 can move smoothly on the screw 2 to achieve the tightening and loosening functions;

[0031] The rubber plug 8 is embedded into the first groove 6 of the bolt head 1, so that it completely fills the first groove 6 and ensures that it fits tightly with the first groove 6 to protect the first groove 6.

[0032] The top of the bolt head 1 is provided with two regular hexagonal grooves (first groove 6 and second groove 7). The first groove 6 is provided with a removable rubber plug 8. When disassembly is required, the plug 8 can be removed from the first groove 6, and the corresponding tool (such as an Allen wrench) can be inserted into the first groove 6 or the second groove 7. This provides additional operating space and torque application point for disassembly, increasing the convenience of disassembly and the diversity of operating methods.

[0033] When stripping occurs at the first groove 6, the bolt head 1 can be operated through the second groove 7, which further facilitates the disassembly of this structure.

[0034] Multiple protrusions 5 are arranged around the bolt head 1 and are integral with the bolt head 1. This not only enhances the structural strength of the bolt head 1, but also allows for disassembly using specialized tools in conjunction with the protrusions 5, such as pliers. This facilitates better clamping of the bolt head 1 by the tools, thereby improving disassembly efficiency.

[0035] The rubber stopper 8 can protect the first groove 6, preventing dust, moisture and other impurities from entering the first groove 6, avoiding rust or damage in the first groove 6 and the second groove 7, thereby ensuring the usability of the first groove 6 and the second groove 7.

[0036] The multiple cavities 9 on the stopper 8 can be moved with the help of a tool, making it easy to remove the stopper 8 from the first groove 6.

[0037] In the description herein, it should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0038] 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.
