Description

Technical Field

[0001] This utility model belongs to the field of bolt assembly technology, specifically relating to a novel high-strength torque-shear bolt for assembly. Background Technology

[0002] New types of high-strength torque-shear bolts for assembly are commonly used to connect components such as steel beams, steel columns, and steel plates. The high strength and reliability of these bolts ensure that the structure can withstand large loads during long-term use and remain stable in harsh environments.

[0003] Chinese Patent Publication No. CN217130049U discloses a novel torsion-shear type high-strength bolt, including a nut. Vertical plates are fixedly connected to the bottom of the nut near both sides. An elastic rod is fixedly connected between the vertical plates. A threaded rod is fixedly connected to the top of the nut, and a tail rod is fixedly connected to the top of the threaded rod. The two vertical plates are symmetrically arranged about the central axis of the nut. The tail rod has an insertion mechanism inside. Through the cooperation of the tail rod, elastic plates, insertion rod, and moving plate, the high-strength bolt can be rotated in another way. A hexagonal rod is inserted into the hexagonal groove at the top of the tail rod. The hexagonal rod drives the elastic plate to compress, the elastic plate drives the insertion rod to move, and the insertion rod drives the moving plate to move. The insertion rod and moving plate limit the insertion of surrounding components, improving the applicability of the device.

[0004] However, the current new type of torque-shear type high-strength bolt has the following problem: it is difficult to adjust the length of the bolt so that the bolt can adapt to different hole depths. Therefore, we propose a new type of torque-shear type high-strength bolt for assembly. Utility Model Content

[0005] The purpose of this invention is to provide a new type of high-strength torque-shear bolt for assembly, which can solve the problem in related technologies that it is difficult to adjust the length of the screw so that the screw can adapt to different hole depths.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A novel high-strength torque-shear bolt for assembly includes a screw and an adjusting groove. The adjusting groove is located at the top of the screw. A connecting ring is fixedly installed on the inner wall of the adjusting groove. A connecting groove is formed on the inner wall of the connecting ring. A connecting rod is slidably installed on the inner wall of the connecting ring. A nut is fixedly installed on the top of the connecting rod. An adjusting assembly is provided on the inner wall of the adjusting groove. The adjusting assembly includes a connecting spring, which is positioned between the connecting rod and the adjusting groove. A square hole is formed on the circumferential surface of the connecting rod. A square plate is fixedly installed on the inner wall of the square hole. A limit rod slides through the front and rear walls of the square plate. A limit spring is provided between the limit rod and the square plate. A limit hole is formed on the circumferential surface of the screw. An installation groove is formed on the circumferential surface of the screw. An arc-shaped panel is slidably installed on the inner wall of the installation groove. After the connecting rod is limited by the limit rod and the limit hole, the length of the screw is extended to match the connection with a deeper hole. By ensuring that the screw can effectively reach the required fixing depth, a more stable connection is provided. The design of the arc-shaped panel effectively prevents the influence of misoperation on the screw length, thus ensuring that its length is not affected by external forces.

[0008] Preferably, the arc panel contacts the limiting hole, and the front side of the limiting rod is set as an arc surface, which can reduce the frictional force when the limiting rod is reset.

[0009] Preferably, the connecting rod contacts the inner wall of the connecting groove, and a spring is provided between the arc panel and the mounting groove, which can drive the arc panel to reset.

[0010] Preferably, the limiting rod abuts against the inner wall of the adjusting groove, and the top of the nut has a polygonal groove, which facilitates the assembly of the screw.

[0011] Preferably, the fastening assembly includes a nut disposed on the circumferential surface of the screw. A fastening rod slides through the upper and lower walls of the nut. A fastening plate is fixedly installed at the bottom of the fastening rod, and a rubber ring is fixedly installed at the top of the fastening rod. The upward pressing of the fastening rod causes the rubber ring to be pressed upward, which makes the rubber ring fit more tightly against the bottom of the connector. When the rubber ring is in closer contact with the bottom of the connector, the pressure can be more effectively distributed, reducing friction and wear on the contact surface, thereby improving the stability of the entire assembly.

[0012] Preferably, the number of fastening rods is set to two, and they are symmetrical to each other along the horizontal central axis of the nut. A fastening spring is provided between the fastening plate and the nut, which can increase the fastening force of the rubber ring.

[0013] The technical effects achieved by this utility model are as follows:

[0014] 1. This utility model allows for flexible adjustment of screw length by adjusting the component settings, thereby ensuring that the screw can effectively reach the required fixing depth and provide a more stable connection. The arc panel shielding design can effectively prevent the impact of misoperation on screw length, thus ensuring that its length is not affected by external forces.

[0015] 2. This utility model, through the design of the fastening components, allows the rubber ring to fit more tightly against the bottom of the connector. This closer contact between the rubber ring and the bottom of the connector more effectively disperses pressure, reducing friction and wear on the contact surfaces. This, in turn, improves the stability of the entire assembly. Attached Figure Description

Detailed Implementation

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5As shown, a novel high-strength torque-shear bolt for assembly includes a screw 1 and an adjusting groove 2. The adjusting groove 2 is formed on the top of the screw 1. A connecting ring 3 is fixedly installed on the inner wall of the adjusting groove 2. A connecting groove 4 is formed on the inner wall of the connecting ring 3. A connecting rod 5 is slidably installed on the inner wall of the connecting ring 3. A nut 6 is fixedly installed on the top of the connecting rod 5. An adjusting assembly is provided on the inner wall of the adjusting groove 2. The adjusting assembly includes a connecting spring 8, which is disposed between the connecting rod 5 and the adjusting groove 2. A square hole 9 is formed on the circumferential surface of the connecting rod 5. A square nut 6 is fixedly installed on the inner wall of the square hole 9. A square plate 10 has a limit rod 11 that slides through its front and rear walls. A limit spring 12 is provided between the limit rod 11 and the square plate 10. A limit hole 13 is provided on the circumferential surface of the screw 1. An installation groove 14 is provided on the circumferential surface of the screw 1. An arc panel 15 is slidably installed on the inner wall of the installation groove 14. By ensuring that the screw 1 can effectively reach the required fixing depth, a more stable connection is provided. The shielding design of the arc panel 15 can effectively prevent the influence of misoperation on the length of the screw 1, thereby ensuring that its length is not affected by external forces.

[0025] The arc panel 15 contacts the limiting hole 13, and the front side of the limiting rod 11 is set as an arc surface. The arc surface can reduce the friction force when the limiting rod 11 is reset.

[0026] The connecting rod 5 contacts the inner wall of the connecting groove 4, and a spring is provided between the arc panel 15 and the mounting groove 14. The arc panel 15 can be reset by the spring.

[0027] The limiting rod 11 abuts against the inner wall of the adjusting groove 2, and the top of the nut 6 has a polygonal groove 7, which facilitates the assembly of the screw 1.

[0028] Based on the above structure, when installing a connector with a deep hole, manually pull the nut 6 upwards. The upward movement of the nut 6 causes the connecting rod 5 to move upwards, which in turn causes the square plate 10 to move upwards. The square plate 10 then causes the limiting rod 11 to move upwards, aligning it with the limiting hole 13. After alignment, the limiting rod 11 moves forward under the force of the limiting spring 12, contacting the inner wall of the limiting hole 13 and limiting the connecting rod 5. The connecting rod 5, limited by the limiting rod 11 and the limiting hole 13, extends the length of the screw 1 to match the connector with the deep hole. To reset the connecting rod 5, manually push the arc panel 15 downwards. The movement compresses the spring 1, causing it to deform and store force. Simultaneously, the arc panel 15 moves downward, disengaging from the limiting hole 13 and releasing its obstruction. After the obstruction of the limiting hole 13 is released, the limiting rod 11 inside the limiting hole 13 is pressed manually. The limiting rod 11 moves backward under the manual pressure, pulling the limiting spring 12. The limiting spring 12 deforms and stores force under the pull of the limiting rod 11. Simultaneously, the limiting rod 11 moves backward, disengaging from the limiting hole 13 and releasing its restriction on the connecting rod 5. After the restriction on the connecting rod 5 is released, the connecting rod 5 moves downward and resets under the elastic force of the connecting spring 8. The downward reset of the connecting rod 5 causes the nut 6 to move downward and reset to its initial position.

[0029] like Figure 1-5 As shown, a fastening assembly is provided on the circumferential surface of screw 1. The fastening assembly includes a nut 161, which is disposed on the circumferential surface of screw 1. A fastening rod 162 slides through the upper and lower walls of the nut 161. A fastening plate 163 is fixedly installed at the bottom of the fastening rod 162, and a rubber ring 164 is fixedly installed at the top of the fastening rod 162. The upward pressing of the fastening rod 162 causes the rubber ring 164 to be pressed upward. The upward pressing of the rubber ring 164 makes it fit more tightly against the bottom of the connector. When the rubber ring 164 is in closer contact with the bottom of the connector, the pressure can be more effectively distributed, reducing friction and wear on the contact surface, thereby improving the stability of the entire assembly.

[0030] Two fastening rods 162 are provided, and they are symmetrical to each other along the horizontal central axis of the nut 161. A fastening spring 165 is provided between the fastening plate 163 and the nut 161. The fastening force of the rubber ring 164 can be increased by the fastening spring 165.

[0031] According to the above structure, when the nut 161 is manually rotated upward to move in conjunction with the screw 1 to tighten the connector, the upward movement of the nut 161 causes the fastening rod 162 to move upward. The upward movement of the fastening rod 162 causes the rubber ring 164 to move upward. The upward movement of the rubber ring 164 contacts the connector and compresses it. The rubber ring 164 moves downward due to the reaction force of the compression of the connector. The downward movement of the rubber ring 164 causes the fastening rod 162 to move downward. The downward movement of the fastening rod 162 causes the fastening plate 163 to move downward, thus tightening the connector. The plate 163 moves downward to pull the fastening spring 165. The fastening spring 165 deforms and stores force under the pull of the fastening plate 163. At the same time, the fastening plate 163 applies an upward force under the reaction force of the fastening spring 165. The fastening plate 163 is squeezed upward by the reaction force of the fastening spring 165. The upward squeeze of the fastening plate 163 drives the fastening rod 162 to squeeze upward. The upward squeeze of the fastening rod 162 drives the rubber ring 164 to squeeze upward. The upward squeeze of the rubber ring 164 makes the rubber ring 164 fit more tightly against the bottom of the connector.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
