Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, and in particular to a shock-resistant bolt. Background Technology

[0002] Bolts are a type of mechanical part, a cylindrical threaded fastener that is fitted with a nut. They consist of a head and a threaded shank and require a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated.

[0003] Bolts, typically used with nuts for rotation and fixing, are used for connecting parts of mechanical equipment. In actual operation, the vibration generated by the mechanical equipment during operation can affect the bolts. Prolonged vibration may cause the bolts to loosen, requiring workers to perform regular inspections and tightening, which reduces safety, increases workers' working time and efficiency, and increases maintenance costs.

[0004] Therefore, this utility model provides an anti-vibration bolt to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-seismic bolt. By pressing and rotating the knob inward, the second cylinder is inserted into the L-shaped groove, and the telescopic rod is pushed into the insertion hole of the hexagonal bolt, ultimately locking the hexagonal bolt. This reduces the likelihood of the hexagonal bolt loosening due to vibration during use, improving safety, service life, and work efficiency, while also reducing maintenance costs. Furthermore, the splicing of multiple fixing plates in the horizontal and vertical directions increases the area of ​​the plates, increases friction, and improves the overall seismic performance and load-bearing capacity.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-vibration bolt, comprising a hexagonal bolt and a locking mechanism, wherein a fixing plate is threaded onto the lower end face of the hexagonal bolt, square grooves are fixedly opened on both sides of the front end of the fixing plate, and square blocks are fixedly arranged on both sides of the rear end of the fixing plate, a long groove is opened through the center of one side of the fixing plate, and a protrusion is fixedly arranged at the center of the other side of the fixing plate;

[0007] The hexagonal bolt has insertion holes at its four corners. The locking mechanism includes a fixing frame, which is fixedly mounted on the upper surface of the fixing plate near the insertion holes. A sleeve is fixedly mounted on the upper surface of the fixing frame. A telescopic rod is slidably mounted inside the sleeve. A tension spring is fixedly mounted on the outside of the telescopic rod. A first cylinder is fixedly mounted at the end of the telescopic rod. A second cylinder is fixedly mounted on the outside of the first cylinder near the tension spring. An L-shaped groove is opened at the lower front end of the sleeve. The second cylinder is slidably mounted inside the L-shaped groove.

[0008] Through the above technical solution, the lower end face of the hexagonal bolt is threaded onto the fixing plate, the square blocks on both sides of the rear end of another fixing plate are snapped into the multiple square grooves of this fixing plate, and the protrusion of another fixing plate is snapped into the long groove of this fixing plate, so as to realize the splicing of multiple fixing plates in the horizontal and vertical directions, increase the area of ​​the plates, increase the friction, and thus improve the overall seismic performance and load-bearing capacity.

[0009] Press the knob inward to push the first cylinder, compressing the tension spring and pushing out the telescopic rod. Insert the telescopic rod into the insertion holes at the four corners of the hexagonal bolt. Rotate the knob to engage the second cylinder in the L-shaped groove, locking the top of the hexagonal bolt to the fixing plate. When the hexagonal bolt needs to be removed, rotate the knob again. Under the action of the tension spring, the telescopic rod quickly springs back. By pressing and rotating the knob inward, the second cylinder is engaged in the L-shaped groove, pushing the telescopic rod into the insertion hole of the hexagonal bolt, ultimately locking the hexagonal bolt. This reduces the likelihood of the hexagonal bolt loosening due to vibration during use, improving safety, service life, and work efficiency, while also reducing maintenance costs.

[0010] Furthermore, a hexagonal screw hole is fixedly opened on the upper end face of the hexagonal bolt;

The operation is simple and quick, and the fastening work can be completed in a short time. It can also be easily disassembled when needed, and has good disassembly capability.

[0012] Furthermore, a rubber pad is fixedly provided on the lower end face of the fixing plate, and a plurality of anti-slip contact points are fixedly provided on the lower end face of the rubber pad;

[0013] Through the above technical solution, a rubber pad with multiple anti-slip contacts is provided on the lower end face of the fixing plate. The multiple anti-slip contacts on the rubber pad can increase the friction with the contact surface, thereby improving the anti-slip ability of the fixing plate and reducing the vibration between the fixing plate and the contact surface.

[0014] Furthermore, the plurality of said blocks are snapped together inside the plurality of square slots;

[0015] The above technical solution allows the square blocks on both sides of the rear end of another panel to be snapped into the multiple square grooves inside this panel, facilitating the longitudinal splicing of panels, increasing the area of ​​the panels, and improving the overall seismic performance and load-bearing capacity.

[0016] Furthermore, the protrusion is snapped into place inside the long groove;

[0017] The above technical solution allows the protrusion of another plate to be engaged inside the long groove of this plate, facilitating the horizontal splicing of plates, increasing the area of ​​the plates, and improving the overall seismic performance and load-bearing capacity.

[0018] Furthermore, a knob is fixedly installed on the side of the first cylinder away from the tension spring;

[0019] Using the above technical solution, pressing the knob pushes it inward, thereby pushing the first cylinder, compressing the tension spring, and realizing the pushing of the internal mechanism so that the internal mechanism can be ejected to complete a specific function.

[0029] 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.

[0030] Example 1

[0031] Reference Figure 1-4 An embodiment of this utility model is provided: an anti-vibration bolt, including a hexagonal bolt 1 and a locking mechanism 9. A fixing plate 4 is threaded on the lower end face of the hexagonal bolt 1. Square grooves 7 are fixedly opened on both sides of the front end of the fixing plate 4. Square blocks 8 are fixedly set on both sides of the rear end of the fixing plate 4. A long groove 5 is opened through the center of one side of the fixing plate 4. A protrusion 6 is fixedly set on the center of the other side of the fixing plate 4.

[0032] The lower end of the hexagonal bolt 1 is threaded onto the fixing plate 4. The square blocks 8 on both sides of the rear end of another fixing plate 4 are snapped into the multiple square grooves 7 of this fixing plate 4. The protrusions 6 of another fixing plate 4 are snapped into the long grooves 5 of this fixing plate 4. This achieves the splicing of multiple fixing plates 4 in the horizontal and vertical directions, increases the area of ​​the plates, increases the friction, and thus improves the overall seismic performance and load-bearing capacity.

[0033] The hexagonal bolt 1 has insertion holes 3 through its four corners. The locking mechanism 9 includes a fixing frame 902, which is fixedly mounted on the upper surface of the fixing plate 4 near the insertion holes 3. A sleeve 901 is fixedly mounted on the upper surface of the fixing frame 902. A telescopic rod 904 is slidably mounted inside the sleeve 901. A tension spring 903 is fixedly mounted on the outside of the telescopic rod 904. A first cylinder 905 is fixedly mounted at the end of the telescopic rod 904. A second cylinder 907 is fixedly mounted on the outside of the first cylinder 905 near the tension spring 903. An L-shaped groove 908 is opened through the lower front end of the sleeve 901. The second cylinder 907 is slidably mounted inside the L-shaped groove 908.

[0034] Pressing knob 906 pushes it inward, thereby pushing cylinder 905, compressing tension spring 903, and pushing out telescopic rod 904. Telescopic rod 904 is then inserted into the insertion holes 3 at the four corners of hexagonal bolt 1. Rotating knob 906 inserts cylinder 907 into L-shaped groove 908, locking the top of hexagonal bolt 1 and fixing plate 4. When hexagonal bolt 1 needs to be removed, rotating knob 906 again causes telescopic rod 904 to spring back quickly under the action of tension spring 903. By pressing and rotating knob 906 inward, cylinder 907 is inserted into L-shaped groove 908, pushing telescopic rod 904 into insertion hole 3 of hexagonal bolt 1, ultimately locking hexagonal bolt 1. This reduces the possibility of hexagonal bolt 1 loosening due to vibration during use, improving safety, service life, and work efficiency, while also reducing maintenance costs.

[0035] The upper end face of the hexagonal bolt 1 is fixed with a hexagonal screw hole 2, the lower end face of the fixing plate 4 is fixed with a rubber pad 10, the lower end face of the rubber pad 10 is fixed with multiple anti-slip contact points 11, multiple square blocks 8 are snapped into multiple square grooves 7, the protrusion 6 is snapped into the long groove 5, and the first cylinder 905 is fixed with a knob 906 on the side away from the tension spring 903.

[0036] By inserting a hex wrench into the hexagonal screw hole 2 and rotating it, the hexagonal bolt 1 is rotated and fixed in the lower mechanism. The operation is simple and quick, and the tightening work can be completed in a short time. Disassembly is also convenient when needed, exhibiting good removability. Multiple anti-slip contact points 11 are provided on the lower end face of the fixing plate 4, forming a rubber pad 10. These anti-slip contact points 11 increase the friction with the contact surface, thereby improving the anti-slip ability of the fixing plate 4 and reducing vibration between the fixing plate 4 and the contact surface. The square blocks 8 on both sides of the rear end of one plate are engaged with the multiple square slots 7 inside the plate, which facilitates the longitudinal splicing of the plates, increases the area of ​​the plates, and improves the overall seismic performance and load-bearing capacity. The protrusion 6 of another plate is engaged with the long slot 5 inside the plate, which facilitates the transverse splicing of the plates, increases the area of ​​the plates, and improves the overall seismic performance and load-bearing capacity. Pressing the knob 906 and pushing it inward will push the first cylinder 905, compressing the tension spring 903, thereby realizing the pushing of the internal mechanism, so that the internal mechanism can be ejected to complete a specific function.

[0037] Working principle: Insert a hex wrench into the hex bolt hole 2 and rotate it to fix the hex bolt 1 in the fixing plate 4 and rubber gasket 10. Press the knob 906 to push it inward, thereby pushing the first cylinder 905, compressing the tension spring 903, and pushing out the telescopic rod 904. The telescopic rod 904 is pushed out and inserted into the insertion holes 3 at the four corners of the hex bolt 1. When it is necessary to remove the hex bolt 1, rotate the knob 906 again. Under the action of the tension spring 903, the telescopic rod 904 quickly springs back. When it is necessary to increase the area of ​​the plate, the square blocks 8 on both sides of the rear end of another fixing plate 4 are engaged with the multiple square grooves 7 of this fixing plate 4, and the protrusions 6 of another fixing plate 4 are engaged with the long grooves 5 of this fixing plate 4, so as to realize the splicing of multiple fixing plates 4 in the horizontal and vertical directions.
