Description

Technical Field

[0001] The present application relates to the technical field of bolts, and in particular to a bolt with adjustable threads. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener equipped with a nut. It is a type of fastener consisting of a head and a cylindrical body with an external thread on the screw. It needs to be matched with a nut and is used to fasten two parts with through holes. This type of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

[0003] At present, the threads of bolts are usually pre-processed products, so it is difficult to adjust the position of the threads on the bolt surface according to the use requirements, which reduces the flexibility of the bolt when connecting with equipment or workpieces. Therefore, in order to solve the above problems, we provide a bolt with adjustable threads. Utility Model Content

[0021] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-4 , the utility model provides a technical solution of a bolt with adjustable thread:

[0023] A thread-adjustable bolt comprises an end cap 1, the left end of the end cap 1 is fixedly connected to a rod body 2, a threaded sleeve 3 is arranged outside the rod body 2, two threaded positioning sleeves 4 are arranged outside the rod body 2, the outer surface of the threaded sleeve 3 is provided with two first positioning grooves 6, the outer surface of the rod body 2 is provided with two groups of second positioning grooves 8, two threaded positioning sleeves 4 are respectively fixedly connected to two first positioning blocks 5 and two second positioning blocks 7 on the side surfaces close to each other, a locking fixing ring 11 is arranged outside the rod body 2, and the outer surfaces of the two threaded positioning sleeves 4 are both threadedly connected to the inner ring of the locking fixing ring 11; specifically, by threading the two threaded positioning sleeves 4 to the inner ring of the locking fixing ring 11, the two threaded positioning sleeves 4 will be locked and fixed, thereby improving the stability of the threaded sleeve 3 after position adjustment.

[0024] In this embodiment, two limiting holes 9 are provided on the outer surface of the rod body 2, and the inner ring of the threaded sleeve 3 is fixedly connected with two limiting blocks 10. The ends of the two limiting blocks 10 that are away from each other extend to the inside of the two limiting holes 9 respectively, and the outer surfaces of the two limiting blocks 10 are slidably connected to the inner walls of the two limiting holes 9 respectively; specifically, through the cooperation of the limiting holes 9 and the limiting blocks 10, the threaded sleeve 3 can be limited when it is sleeved on the surface of the rod body 2, which is convenient for precise positioning of the threaded sleeve 3 when adjusting its position.

[0025] In this embodiment, the outer surface of the locking and fixing ring 11 is fixedly connected to a rotating plate 12, two grooves 14 are provided on the left side of the threaded sleeve 3, and a model plate 13 is fixedly connected to the right side of the end head 1. The ends of the two first positioning blocks 5 close to each other extend to the inside of the two first positioning grooves 6 respectively, and the outer surfaces of the first positioning blocks 5 contact the inner walls of the first positioning grooves 6, and the ends of the two second positioning blocks 7 close to each other extend to the inside of the two second positioning grooves 8 respectively, and the outer surfaces of the second positioning blocks 7 contact the inner walls of the second positioning grooves 8; specifically, through the provision of the rotating plate 12, it is convenient to rotate the locking and fixing ring 11, and the grooves 14 are used to facilitate the taking of the threaded sleeve 3. Through the cooperation of the second positioning grooves 8, the first positioning grooves 6, the first positioning blocks 5 and the second positioning blocks 7, the threaded sleeve 3 can be positioned after the position is adjusted.

[0026] Working principle: When adjusting the position of the threaded sleeve 3 on the surface of the rod body 2, first loosen the rotating plate 12 with a wrench, which can drive the locking and fixing ring 11 to move to the right, thereby releasing the fixation of the two threaded positioning sleeves 4, and then remove the two threaded positioning sleeves 4. The threaded sleeve 3 can be slid left and right through the two grooves 14 and adjusted to a suitable position. After the position of the threaded sleeve 3 on the surface of the rod body 2 is adjusted, take the two threaded positioning sleeves 4 again, and insert the first positioning block 5 into the first positioning groove 6, and the second positioning block 7 into the second positioning groove 8, respectively. Then, rotate the locking and fixing ring 11 to the left, and the surfaces of the two threaded positioning sleeves 4 will be connected to the inner circle threads of the locking and fixing ring 11, thereby completing the position adjustment of the threaded sleeve 3 on the surface of the rod body 2.
