Description

Technical Field

[0001] The utility model belongs to the technical field of studs, and particularly relates to a stud convenient for installation. Background Art

[0002] A stud refers to a cylindrical fastener with threads, and generally needs to be used in combination with a nut for fastening installation. There are various types of studs, including double-headed studs that can be thread-connected at both ends.

[0003] At present, the Chinese utility model with the publication number of CN210830071U discloses a stud convenient for installation. In the use of existing double-headed studs, they are often installed on some large machinery. When these machineries work, they will generate large vibrations, which will cause the originally fastened nuts to rotate and loosen from the studs over a long time, affecting the fastening performance of the stud connection and having certain potential safety hazards. At the same time, since both ends of the double-headed stud can be used, during the use process, the threads at one end are often damaged while the other end is still intact. Since they cannot be disassembled, only both ends of the double-headed stud can be discarded and replaced simultaneously, resulting in certain waste and relatively low practicability. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a stud convenient for installation, which has the advantages of improving the fastening performance between the stud and the nut, facilitating the splicing and installation of the stud, and having the function of disassembling and separately discarding and replacing the damaged end.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A stud convenient for installation includes a first stud and a second stud. Second limiting grooves are provided at the threaded ends on the surfaces of the first stud and the second stud. A nut is threadedly sleeved on the surface of the first stud. A placement groove is provided inside the nut. A limiting ring is slidably connected inside the nut through the placement groove. First limiting grooves are provided on both sides of the inner surface of the placement groove. First fixing blocks slidably connected with the first limiting grooves are welded on the outer surface of the limiting ring. Second fixing blocks slidably connected with the second limiting grooves are welded on the inner surface of the limiting ring.

[0006] By adopting the above technical solutions, after the nut and the stud are threadedly fastened, a limiting ring is installed inside the nut, and the first limiting grooves, the first fixing blocks, the second limiting grooves and the second fixing blocks are used for clamping and limiting each other. Thus, the nut cannot rotate on the surface of the stud, which can effectively prevent the nut from vibrating and loosening and improve the fastening stability of the bolt connection. By using the insertion rod and the insertion slot for insertion and the limiting blocks sliding inside the sliding groove and the clamping slot respectively, the first stud and the second stud are clamped and assembled, so as to facilitate the installation of the stud. At the same time, it is also convenient to replace the damaged stud at the other end, improving the practicability.

[0007] The utility model is further configured as follows: an insertion rod is welded to one end of the first stud close to the second stud, a slot slidably connected to the insertion rod is opened at one end of the second stud close to the first stud, a limiting block is welded on the surface of the insertion rod, and a sliding groove and a card groove are respectively opened on the slot that are slidably connected to the limiting block.

[0008] The above technical solution is adopted to facilitate the installation and connection of the studs, and also facilitate the replacement of the damaged studs at the other end, thereby improving practicality.

[0009] The utility model is further configured as follows: the slide groove is connected to the limit block in a radial sliding manner, and the clamping groove is connected to the limit block in an axial sliding manner.

[0010] By adopting the above technical solution, it is convenient to install and disassemble the first stud and the second stud by means of the limiting blocks respectively inside the sliding groove and the clamping groove.

[0011] The utility model is further configured as follows: a magnet ring which is magnetically attracted to the nut is fixedly sleeved on the surface of the limiting ring.

[0012] By adopting the above technical solution, the limiting ring is adsorbed and fixed to prevent the limiting ring from accidentally slipping out of the interior of the nut.

[0013] The utility model is further configured as follows: an end of the second stud surface close to the first stud is slidably connected with a sliding plate, and an end of the first stud surface close to the second stud is provided with a connecting groove slidably plugged with the sliding plate.

[0014] By adopting the above technical solution, the sliding plate is slidably inserted into the connecting groove, so that the first stud and the second stud can be connected and limited to prevent accidental rotation from causing the limit block to slip out of the slot.

[0015] The utility model is further configured as follows: the top of the sliding plate is provided with anti-slip lines.

[0016] The above technical solution is adopted to increase the friction force, making it easier to move the sliding plate forward and backward.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. After the nut and the stud are threadedly connected, a limiting ring is installed inside the nut, and the first limiting groove and the first fixing block as well as the second limiting groove and the second fixing block are mutually engaged and limited. This prevents the nut from rotating on the surface of the stud, effectively preventing the nut from vibrating and loosening, and improving the stability of the bolt connection;

[0019] 2. By using the insertion rod and the slot for insertion connection, and sliding the limiting blocks inside the sliding groove and the clamping groove respectively, the first stud and the second stud are clamped and assembled, so as to facilitate the installation of the studs. At the same time, it is also convenient to replace the damaged stud at the other end, improving the practicability. BRIEF DESCRIPTION OF THE DRAWINGS
