Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a shear-resistant bolt. Background Technology

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is used with a nut. It consists of a head and a threaded shank and is used to fasten two parts with through holes. This type of connection is called a bolted connection. According to the shape of the head, there are hexagonal head, round head, square head, countersunk head, etc., among which the hexagonal head is the most commonly used.

[0003] Chinese patent publication number "CN211975624U" discloses "a bolt with strong shear resistance, comprising a column and a connector. The connector is located on one side of the column. A first arc-shaped groove is formed on the right side of the connector. A second arc-shaped groove is formed on the inner wall of the first arc-shaped groove near both sides. A through groove is formed inside the connector and on one side of the first arc-shaped groove. A pull ring is movably connected to one side of the second arc-shaped groove. A pull rope is movably connected to one side of the pull ring. A connecting groove is formed on the left side of the connector. A protrusion is fixedly connected to the right side of the column. A first slot is formed on one side of the protrusion. A fixing block is fixedly installed on the bottom inner wall of the first slot. Gunpowder is placed inside the first slot and on one side of the fixing block. First grooves are formed on the upper and lower inner walls of the first slot. A second slot is formed on the outer wall of the column. A fitting block is movably installed inside the second slot. The fitting block..." The top is fixedly connected to a connecting block, and a movable shaft is movably installed on the side of the connecting block near the front. This patent works by pulling a pull ring a certain distance away from the connector, rotating the pull ring 90 degrees, and releasing the pull ring. Under the action of a spring, the spring pushes the sealing block and the metal block to move, causing one end of the metal block to move quickly towards the side of the fixed block. When the surface of the metal block touches the surface of the fixed block, the friction between the two blocks generates sparks, igniting the gunpowder located inside the first groove. At the same time, due to the setting of the first and second grooves, the inner wall of the column located at the first and second grooves breaks, causing the bolt head at one end of the column to detach from one end of the connector. The column remains inside the threaded opening, preventing other personnel from twisting the bolt. However, the above patent requires the destruction of the entire bolt when in use. Once the entire bolt is destroyed, the overall strength of the bolt will decrease, resulting in a decrease in the bolt's shear resistance, which makes the bolt less practical. Therefore, we propose a shear-resistant bolt. Utility Model Content

[0004] The purpose of this utility model is to provide a shear-resistant bolt to solve the problem proposed in the background art, which requires the bolt to be destroyed when in use. Once the bolt is destroyed, the overall strength of the bolt will decrease, resulting in a decrease in the bolt's shear resistance and making the bolt less practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shear-resistant bolt, comprising a column and a connecting groove, wherein the connecting groove is formed at the top of the column, a locking block is fixedly connected to the bottom of the inner cavity of the connecting groove, a connecting post is inserted into the inner cavity of the connecting groove, a locking groove is formed at the bottom of the connecting post, a head is fixedly connected to the top of the connecting post, and a second mounting groove is formed on the left and right side walls of the connecting post, wherein springs are fixedly connected to the left and right side walls of the inner cavity of the second mounting groove.

[0006] As a further description of the above technical solution:

[0007] The outer side wall of the column is provided with a first mounting groove on the front and rear sides. The inner cavity of the first mounting groove is slidably connected with a retaining block. The front and rear side walls of the retaining block are provided with anti-slip texture.

[0008] As a further description of the above technical solution:

[0009] A push rod is fixedly connected to the inner wall of the clamping block, and the end of the push rod passes through the first mounting groove and extends into the inner cavity of the column.

[0010] As a further description of the above technical solution:

[0011] The bottom of the column is provided with a groove, and a conical block is slidably connected to the inner cavity of the column.

[0012] As a further description of the above technical solution:

[0013] A vertical rod is fixedly connected to the bottom of the conical block. The end of the vertical rod passes through the column and extends to the bottom of the column. A base block is fixedly connected to the end of the vertical rod.

[0014] As a further description of the above technical solution:

[0015] The end of the spring is fixedly connected to a connecting block, which is fixedly connected to the left and right side walls of the inner cavity of the connecting groove.

[0016] As a further description of the above technical solution:

[0017] The second mounting groove has limit grooves at the top and bottom of its inner cavity, and a limit block is slidably connected to the inner cavity of the limit groove. The limit block is fixedly connected to the top and bottom of the connecting block.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This shear-resistant bolt is inserted into the connecting groove via a connecting post, allowing the bolt head and post to slide to a certain extent when subjected to shear force. The connecting block and spring work together to buffer the shear force, thereby reducing the shear force on the bolt and improving its overall shear resistance. This results in a bolt with strong shear resistance and improved bolt performance.

[0020] 2. This shear-resistant bolt, when tightened, gradually penetrates into the threaded hole. At this time, the bottom block abuts against the bottom of the threaded hole cavity. As the bolt gradually penetrates, the vertical rod pushes the conical block, which in turn pushes the push rod. The push rod then moves the clamping block out of the first mounting groove, causing the clamping block to contact the inner wall of the threaded hole. This increases the friction between the bolt and the threaded hole, preventing the bolt from loosening during subsequent use. This ensures that the bolt is more stably screwed into the threaded hole, preventing it from loosening during use. Attached Figure Description

[0030] This invention provides a shear-resistant bolt with strong shear resistance, improving bolt performance and ensuring a more stable connection in the bolt hole, preventing loosening during use. Please refer to [link / reference]. Figure 1-5 It includes a column 100 and a connecting groove 200;

[0031] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5The outer side wall of the column 100 has first mounting grooves 110 on both the front and rear sides. A retaining block 120 is slidably connected to the inner cavity of the first mounting groove 110. Anti-slip textures 121 are provided on the front and rear side walls of the retaining block 120. A push rod 130 is fixedly connected to the inner wall of the retaining block 120. The end of the push rod 130 passes through the first mounting groove 110 and extends into the inner cavity of the column 100. A groove 140 is provided at the bottom of the column 100. A conical block 150 is slidably connected to the inner cavity of the column 100. A vertical rod 160 is fixedly connected to the bottom of the conical block 150. The end of the vertical rod 160 passes through the column 100 and... Extending to the bottom of the column 100, and with the end of the vertical rod 160 fixedly connected to a bottom block 170, by tightening the bolt, the bolt gradually penetrates into the screw hole. At this time, the bottom block 170 will abut against the bottom of the screw hole cavity. As the bolt gradually penetrates, the vertical rod 160 pushes the conical block 150, and then the conical block 150 pushes the push rod 130, causing the push rod 130 to move the clamping block 120 out of the first mounting groove 110, and then the clamping block 120 comes into contact with the inner wall of the screw hole, thereby increasing the friction between the bolt and the screw hole and preventing the bolt from loosening during subsequent use.

[0032] In summary, this ensures that the bolts are more securely screwed into the bolt holes, preventing them from loosening during use.

[0033] Please see Figure 1-3 A connecting groove 200 is formed at the top of the column 100. A locking block 210 is fixedly connected to the bottom of the inner cavity of the connecting groove 200. A connecting post 220 is inserted into the inner cavity of the connecting groove 200. A locking groove 230 is formed at the bottom of the connecting post 220. A head 240 is fixedly connected to the top of the connecting post 220. Second mounting grooves 250 are formed on the left and right side walls of the connecting post 220. Springs 260 are fixedly connected to the left and right side walls of the inner cavity of the second mounting groove 250. A connecting block 270 is fixedly connected to the end of the spring 260. The connecting block 270 is fixedly connected to the left and right side walls of the inner cavity of the connecting groove 200. The inner top and bottom of the mounting groove 250 are provided with limiting grooves 280. The inner cavity of the limiting groove 280 is slidably connected to a limiting block 290. The limiting block 290 is fixedly connected to the top and bottom of the connecting block 270. It is inserted into the connecting groove 200 through the connecting post 220, so that when the bolt is subjected to shear force, the bolt head 240 and the post 100 can slide to a certain extent. Then, through the cooperation of the connecting block 270 and the spring 260, the shear force is buffered, and the bolt is able to relieve the shear force to a certain extent, thereby improving the overall shear resistance of the bolt.

[0034] In summary, this gives the bolts strong shear resistance and improves their performance.

[0035] In practical use, those skilled in the art first align the bolt with the screw hole and screw it in. During the tightening process, the bottom block 170 will abut against the bottom of the screw hole cavity. As the bolt gradually goes in, the vertical rod 160 pushes the conical block 150, which in turn pushes the push rod 130. The push rod 130 then moves the clamping block 120 out of the first mounting groove 110, causing the clamping block 120 to come into contact with the inner wall of the screw hole. When the bolt is fully screwed into the screw hole, the bottom block 170 will enter the groove 140. During the use of the screw hole, if the bolt is subjected to shear force, the bolt head 240 and the column 100 will slide to a certain extent. At the same time, the connecting block 270 and the spring 260 work together to buffer the shear force, thereby allowing the bolt to unload the shear force it receives.
