Description

Technical Field

[0001] The utility model relates to the field of triangular thread bolts, in particular to a high-strength triangular thread bolt. Background Art

[0002] A triangular thread screw is a screw with a triangular thread shape that is often used to fasten and connect parts that need to withstand heavy loads. Its thread shape helps provide a more secure connection, especially under vibration and torsional stress. Triangular thread screws are usually made of high-strength steel and are heat-treated to increase their strength and hardness. This type of screw is commonly used in construction, automotive, machinery, and aerospace. Compared with other types of screws, triangular thread screws require special wrenches or wrench heads for installation and removal to ensure the correct torque and thread depth.

[0003] When the existing screws are used, they need to be screwed and fixed by nuts after being rotated through the threads, otherwise they will loosen. When the existing screws encounter products with relatively hard hardness, they lack good self-tapping properties and cannot be better penetrated into the products. Secondly, the bolt cap of the triangular threaded screw is relatively thin, resulting in low strength of the bolt cap. In order to enhance the strength of the bolt cap of the triangular threaded screw, the thickness of the bolt cap can be increased. However, simply increasing the thickness of the bolt cap will result in more materials required, increasing the manufacturing cost. Utility Model Content

[0004] The utility model aims to provide a high-strength triangular thread bolt, which solves the problem that the screws in the prior art lack good self-attachment when encountering products with relatively hard hardness, and cannot better attack into the products.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-strength triangular thread bolt, comprising a bolt body, the upper end of the bolt body is fixedly connected with a bolt head, the upper end of the bolt head is fixedly connected with a connecting piece, the bottom of the bolt body is fixedly connected with a triangular tooth, and the interior of the connecting piece is provided with a mounting groove;

[0006] A hexagonal hole is formed in the middle of the installation groove, and two ends of the hexagonal hole are formed with slotted holes.

[0007] As a further description of the above technical solution: grooves are provided at the four ends of the bolt head.

[0008] As a further description of the above technical solution: a gasket is fixedly connected to the lower end of the bolt head, and the lower end of the gasket is connected to the bolt body.

[0009] As a further description of the above technical solution: limiting grooves are provided at both ends of the installation groove, and limiting blocks are correspondingly arranged inside the limiting grooves.

[0010] As a further description of the above technical solution: a protective plate is fixedly connected to the inner side of the limit block, and a handle is fixedly connected to the outer end of the protective plate.

[0011] The utility model has the following beneficial effects:

[0012] 1. Compared with the prior art, the high-strength triangular thread bolt has triangular teeth at the bottom. The triangular teeth can reduce the resistance during the locking process compared with ordinary thread bolts. It taps the workpiece at three points. There will be a thermal effect during the locking process. After cooling, it will prevent the bolt from moving, thereby improving the strength of the entire bolt. By opening a groove on the bolt head, it is convenient for users to take it and can reduce costs.

[0013] 2. Compared with the prior art, this high-strength triangular threaded bolt can improve the use effect of the entire bolt by setting a hexagonal hole and a slotted hole, and can protect the installation groove by setting a protective plate to prevent dust from entering and affecting the opening and locking of the bolt.

[0014] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
