[0001] The utility model relates to the technical field of bolts, in particular to a new type of anti-fracture bolt. Background Art

[0002] Bolts are indispensable in daily life and industrial production. Bolts are also called the rice of industry, which shows that bolts are widely used. In the field of engineering machinery, bolts are usually used to connect mechanical parts. Bolts are usually equipped with nuts to complete the fastening work. At the same time, bolts can also complete the fastening work alone. For example, one component is set with a through hole, and the other component is set with a screw hole corresponding to the through hole. The bolt passes through the through hole and is screwed into the screw hole to complete the fastening of the two components.

[0003] The fracture resistance of existing bolts is relatively general, and engineering machinery will generate vibration during operation. Long-term vibration can easily cause the bolt head and screw to break, thereby affecting the work quality. At the same time, since the bolt breaks in the screw hole, it is extremely difficult to remove it, requiring professional tools, which is extremely troublesome and greatly increases the workload of the staff. Based on this, this solution provides a new type of fracture-resistant bolt to solve the above-mentioned problems. Utility Model Content

At the same time, the screw, reinforcement rib and nut in the device can be separated. When the screw breaks in the hole, the nut and the screw can be separated and the reinforcement rib is pulled out of the screw, so that the broken screw can be quickly taken out of the hole.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0019] Reference Figure 1-3 As shown, a new type of anti-fracture bolt includes a screw rod 1, a first thread 101, a second thread 102 and a third thread 103 are provided on the surface of the screw rod 1, a through groove 104 is provided through the middle of the screw rod 1, the screw rod 1 is threadedly connected to the nut 6 through the first thread 101, and the screw rod 1 is threadedly connected to the aluminum alloy pressure ring 7 through the second thread 102. By providing the aluminum alloy pressure ring 7, the aluminum alloy pressure ring 7 is threadedly installed on the outside of the screw rod 1, and the nut 6 is matched to realize the tightening of the screw rod 1 as a whole, thereby enhancing the bearing capacity of the bolt as a whole, thereby extending the service life of the bolt, the screw rod 1 is threadedly connected to the nut 2 through the third thread 103, and the surface of the screw rod 1 is fixed. A rubber ring 4 is connected and disposed between the first thread 101 and the second thread 102. The rubber ring 4 fits tightly against the hole wall after entering the mounting hole, thereby enhancing the friction between the screw 1 and the hole wall. When the workpiece is subjected to vibration, the pulling force of the vibration on the screw 1 can be reduced and the pulling force of the vibration can be dispersed throughout the screw 1, so that the screw 1 is evenly stressed and prevented from breaking. A reinforcing rib 5 is disposed within the through groove 104. The left end of the reinforcing rib 5 is threadedly connected to the nut 2. The device is provided with the reinforcing rib 5. By providing the reinforcing rib 5, the overall strength of the screw 1 is increased. A buffer assembly 3 is provided at the right end of the nut 2. The buffer assembly 3 can provide a buffering effect against vibrations caused by mechanical operation, thereby improving the overall impact resistance of the bolt to a certain extent.

[0020] Specifically, in this embodiment, a first connecting groove 201 and a second connecting groove 202 are opened in the middle of the right end of the nut 2, and the first connecting groove 201 and the second connecting groove 202 are connected, and a plurality of groups of installation cavities 203 are evenly opened on the outer side of the right end of the nut 2.

[0021] Specifically, in this embodiment, the buffer assembly 3 includes a moving ring 301 and a spring damper 305. The right end of the moving ring 301 is fixedly connected to the soft pad 302, the left end of the moving ring 301 is fixedly connected to the connecting column 303, the other end of the connecting column 303 is slidably connected to the installation cavity 203, and the outer side of the connecting column 303 is provided with a spring member 304. The two ends of the spring member 304 are respectively fixedly connected to the right end of the nut 2 and the left end of the moving ring 301. During the fixing process, the right end of the moving ring 301 abuts against the left end of the aluminum alloy pressure ring 7. At this time, the action of the spring member 304 causes the moving ring 301 to apply a force to the aluminum alloy pressure ring 7, thereby squeezing the aluminum alloy pressure ring 7 and fixing it to prevent it from shifting due to vibration.

[0022] Specifically, in this embodiment, the spring damper 305 is fixedly installed inside the mounting cavity 203, and the movable end of the spring damper 305 is fixedly connected to the left end of the connecting column 303. When subjected to vibration or impact, the movable ring 301 and the soft pad 302 are forced to move, thereby driving the spring damper 305 to move. The spring damper 305 can weaken the impact force, protecting the connection between the nut 2 and the screw 1, thereby preventing breakage.

[0023] Specifically, in this embodiment, the reinforcing rib 5 includes a main body 501, the cross-section of which is a regular hexagon as a whole, matching the shape of the second thread 102, the right end of the main body 501 is fixedly connected to the limiting plate 502, and the left end of the main body 501 is fixedly connected to the connecting block 503, the surface of the connecting block 503 is provided with a connecting thread 504, and the connecting block 503 is threadedly connected to the nut 2 via the connecting thread 504. By providing the reinforcing rib 5, the overall strength of the screw 1 is improved. At the same time, the screw 1, the reinforcing rib 5 and the nut 2 in this device are all connected by threads, so that the three can be separated. When the screw 1 breaks in the hole, the broken screw 1 can be quickly taken out of the hole by separating the nut 2 and the nut 6 from the screw 1 and pulling the reinforcing rib 5 out of the screw 1. At the same time, the various parts in this device are interchangeable, thereby reducing the cost of use.

[0024] The working principle of the present invention is as follows: when the device is used, the reinforcing rib 5 is aligned and inserted into the through groove 104, and then the reinforcing rib 5 and the screw 1 are connected to the first connecting groove 201 and the second connecting groove 202 on the nut 2, and are threadedly connected by rotation, and then the screw 1 is inserted into the mounting hole, and the screw 1 is fixed by rotating the nut 6 and the aluminum alloy pressure ring 7 to complete the bolt installation.

[0025] In this device,

[0026] By being provided with the buffer assembly 3, it can produce a buffering effect on the vibration caused by the mechanical operation, and to a certain extent improve the overall impact resistance of the bolt. During the fixing process, the right end of the movable ring 301 abuts against the left end of the aluminum alloy pressure ring 7. At this time, the movable ring 301 exerts a force on the aluminum alloy pressure ring 7 through the action of the spring member 304, thereby squeezing the aluminum alloy pressure ring 7 and fixing it to prevent it from shifting due to vibration. At the same time, when subjected to vibration or impact force, the movable ring 301 and the soft pad 302 are forced to move, thereby driving the spring damper 305 to move. The spring damper 305 can weaken the impact force, protect the connection between the nut 2 and the screw 1, and thus avoid breakage.

[0027] By providing the rubber ring 4, after the rubber ring 4 enters the mounting hole, it fits tightly against the hole wall, thereby increasing the friction between the screw 1 and the hole wall. When the workpiece is vibrated, the pulling force of the vibration on the screw 1 can be reduced and the vibration pulling force can be dispersed to the entire screw 1, so that the screw 1 is evenly stressed and the screw 1 is prevented from breaking.

[0028] By providing the reinforcing rib 5, the overall strength of the screw 1 is improved. At the same time, the screw 1, the reinforcing rib 5 and the nut 2 in the device are all connected by threads, so that the three can be separated. When the screw 1 breaks in the hole, the broken screw 1 can be quickly taken out of the hole by separating the nut 2 and the nut 6 from the screw 1 and pulling out the reinforcing rib 5 from the screw 1. At the same time, the various parts in the device are interchangeable, thereby reducing the cost of use.
