Description

Technical Field

[0001] This application relates to the field of fasteners, and more particularly to a bolt assembly with a washer. Background Technology

[0002] A bolt is a type of fastener consisting of a head and a shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection.

[0003] During the use of bolts, in order to protect the parts to be tightened from scratches on the bolt head and to distribute the pressure of the bolt head on the connecting parts, washers are often put on the bolt shank. However, traditionally, bolts and washers are two separate parts, and people need to manually put on the washers separately when using bolts. As a result, the washers may come off the bolts during installation, which affects the convenience of using the washers. Utility Model Content

[0004] To improve the ease of installation of washers, this application provides a bolt assembly with washers.

[0005] The bolt assembly with washer provided in this application adopts the following technical solution: a bolt assembly with washer includes a screw, a smooth rod fixedly installed on the screw, and a bolt head fixedly installed on the smooth rod. The smooth rod is provided with a washer, and the smooth rod is provided with a limiting mechanism for limiting the installation of the washer.

[0006] The limiting mechanism includes mounting grooves symmetrically opened on the outer surface of one side of the optical rod. A first telescopic rod and a second telescopic rod are fixedly installed in the mounting grooves. A first telescopic spring and a second telescopic spring are respectively sleeved on the first telescopic rod and the second telescopic rod. The output ends of the first telescopic rod and the second telescopic rod are fixedly installed with the same mounting plate. A first threaded tooth, a second threaded tooth and a third threaded tooth are fixedly installed on one side of the mounting plate.

[0007] By adopting the above technical solution, the mounting plate is loosened by placing the washer on the smooth rod, and it will automatically reset through the first, second and third threaded teeth. The first, second and third threaded teeth can then limit the installation of the washer, thus avoiding the phenomenon of the washer coming off the bolt during installation and improving the convenience of using the washer.

[0008] Preferably, two sliding grooves are symmetrically formed on one side of the light rod, and a sliding block is slidably installed in each of the two sliding grooves. Both sliding blocks are fixedly connected to the mounting plate.

[0009] By adopting the above technical solution, the sliding groove and sliding block can be set to limit the movement.

[0010] Preferably, the lengths of both sliding blocks are less than the lengths of the corresponding sliding grooves.

[0011] By adopting the above technical solution, the length of the sliding block must be less than the length of the corresponding sliding groove, thus facilitating its movement and use.

[0012] Preferably, the first, second, and third serrations are the same size and are arranged in parallel.

[0013] By adopting the above technical solution, the first, second, and third teeth are the same size and are arranged in parallel, thereby supporting and limiting the position of the washer.

[0014] Preferably, the first, second, and third teeth are all located below and in contact with the washer.

[0015] By adopting the above technical solution, the first, second, and third teeth are all located below and in contact with the washer, which facilitates the positioning and installation of the washer.

[0016] Preferably, the top of the washer is spherical.

[0017] By adopting the above technical solution, the washer is spherical, which has a backstop function. During tightening, there is stress in the bolt axial direction, which increases the friction between the threads. With this configuration, the tightened object is not easy to loosen.

[0018] Preferably, the bottom of the washer is provided with two symmetrical reinforcing blocks, both of which are triangular in shape.

[0019] By adopting the above technical solution, the stability during installation can be improved by using reinforcing blocks, thereby increasing the installation strength of the connection.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application employs a first threaded joint, etc., which, through the combined action of the first telescopic rod, the first telescopic spring, the second telescopic rod, and the second telescopic spring, causes the first threaded joint, the second threaded joint, and the third threaded joint to move inward, thereby placing the washer onto the smooth rod, thus loosening the mounting plate. The first threaded joint, the second threaded joint, and the third threaded joint will automatically reset, thus limiting the installation of the washer through the first threaded joint, the second threaded joint, and the third threaded joint. Therefore, it can prevent the washer from coming off the bolt during installation and improve the convenience of using the washer.

[0022] 2. This application uses a spherical or similar mating mechanism, with the washer being spherical, which provides a locking function. During tightening, there is axial stress on the bolt, increasing the friction between the threads. With this configuration, the tightened object is not easy to loosen, and the reinforcing block can improve the stability during installation, thereby increasing the installation strength of the connection.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a bolt assembly with a washer.

[0030] Reference Figure 1-3 A bolt assembly with a washer includes a screw 1, a smooth rod 2 fixedly mounted on the screw 1, a bolt head 3 fixedly mounted on the smooth rod 2, a washer 4 disposed on the smooth rod 2, a limiting mechanism disposed inside the smooth rod 2 for limiting the installation of the washer 4, and a reinforcing mechanism disposed on the washer 4.

[0031] The limiting mechanism includes mounting grooves 8 symmetrically opened on one side of the outer surface of the light rod 2, and a first telescopic rod 13 and a second telescopic rod 14 are fixedly installed in the mounting grooves 8 respectively. A first telescopic spring 12 and a second telescopic spring 17 are respectively sleeved on the first telescopic rod 13 and the second telescopic rod 14. The output ends of the first telescopic rod 13 and the second telescopic rod 14 are fixedly installed with the same mounting plate 9. A first tooth 5, a second tooth 15 and a third tooth 16 are fixedly installed on one side of the mounting plate 9 respectively. Two sliding grooves 10 are symmetrically opened on one side of the light rod 2. Two sliding blocks 11 are slidably installed in the two sliding grooves 10. The two sliding blocks 11 are fixedly connected to the mounting plate 9. The length of the two sliding blocks 11 is less than the length of the corresponding sliding groove 10. The first tooth 5, the second tooth 15 and the third tooth 16 are the same size and are arranged in parallel. The first tooth 5, the second tooth 15 and the third tooth 16 are all located below the washer 4 and are in contact with it.

[0032] In use, by fitting the washer 4 onto the smooth rod 2, the mounting plate 9 is loosened, and it will automatically reset through the first thread 5, the second thread 15, and the third thread 16. The first thread 5, the second thread 15, and the third thread 16 can then limit the installation of the washer 4, thus preventing the washer 4 from coming off the bolt during installation and improving the convenience of using the washer 4.

[0033] Reference Figure 2-4 The reinforcing mechanism includes two reinforcing blocks 6 symmetrically arranged at the bottom of the washer 4, both of which are triangular in shape, and the top of the washer 4 is a spherical surface 7.

[0034] When in use, the washer 4 is a spherical surface 7, which has a backstop function. When tightening, there is axial stress on the bolt, which increases the friction between the threads. With this configuration, the tightened object is not easy to loosen, and the reinforcing block 6 can improve the stability during installation, thereby improving the installation strength of the connection.

[0035] The implementation principle of a bolt assembly with a washer in this application embodiment is as follows: In use, by pressing the corresponding mounting plate 9, the mounting plate 9 is moved, which compresses the corresponding first telescopic rod 13, first telescopic spring 12, second telescopic rod 14, and second telescopic spring 17. At this time, the first thread 5, second thread 15, and third thread 16 will move inward, and the washer 4 will be fitted onto the smooth rod 2, thereby releasing the mounting plate 9. The first thread 5, second thread 15, and third thread 16 will automatically reset, and the first thread 5, second thread 15, and third thread 16 can limit the installation of the washer 4. Therefore, the phenomenon of the washer 4 coming off the bolt during installation can be avoided, and the convenience of using the washer 4 can be improved.

[0036] The washer 4 is spherical 7, which has a backstop function. When tightening, there is stress in the axial direction of the bolt, which increases the friction between the threads. With this configuration, the tightened object is not easy to loosen, and the reinforcing block 6 can improve the stability during installation, thereby improving the installation strength of the connection.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
