Embodiment 1

[0034] refer to Figure 1-3 , The present embodiment discloses an anti-off connector, which includes a connecting sleeve 1 and an anti-off part; the anti-off part includes a limiting hole 12, a steel ball 2, and a spring 3.

[0035] The inner wall of the connecting sleeve 1 is provided with threaded threads, and the outer wall is provided with a limit hole 12 along the tangential direction of the inner cavity. 3. The top of the limit hole 12 is fixedly connected with the cover 4, and the steel ball 2 is limited at the bottom of the limit hole 12. Under the restriction of the steel ball 2 and the cover 4, the spring 3 is under pressure, and the limit hole 12 is preferably circular hole.

[0036] In this embodiment, the steel ball 2 is located between the threaded wires on the inner wall of the connecting sleeve 1 .

[0037] In this embodiment, the bottom of the limiting hole 12 can be set as a flat bottom or an arc bottom matching the steel ball 2 .

[0038] In this embodime...

Embodiment 2

[0044] refer to Figure 4-5 The difference between the second embodiment and the first embodiment is that the connecting sleeve 1 also includes a stud 5, and the stud 5 is fixedly connected to one end of the connecting sleeve 1 by means of coaxial fixing or angle fixing, and the anti-loosening part is arranged on the connecting Set the other end of 1 to suit different connection needs.

Embodiment 3

[0046] refer to Figure 6 The difference between the third embodiment and the first embodiment is that the two ends of the connection sleeve 1 are respectively provided with anti-slip prevention parts in opposite directions to meet different connection requirements.

[0047]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Abstract

The invention discloses an anti-falling connecting piece, a machining method and a using method. The anti-falling connecting piece comprises a connecting sleeve, a steel ball and a spring, wherein a limiting hole is formed in the outer wall of the connecting sleeve in the tangential direction of an inner cavity, the bottom of the limiting hole communicates with the inner cavity of the connecting sleeve, the steel ball and the spring are sequentially installed in an inner cavity of the steel ball, and a sealing cover is fixedly connected to the outer side of the limiting hole; the steel ball is located at the bottom of the limiting hole, the spring is located between the steel ball and the sealing cover, the steel ball is stressed under the normal condition, and the size of a through hole, communicating with the inner cavity of the connecting sleeve, of the bottom of the limiting hole is smaller than the diameter of the steel ball; the steel ball is jacked back to an inner cavity of the limiting hole by a to-be-connected piece when the connecting sleeve and a to-be-connected component are cooperated to be screwed up in a swirling mode, so that the problems of loosening and wire falling of a fastener and electrokinetic welding are effectively solved, and on-site safe operation is facilitated.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a detachment-preventing connector, a processing method and a using method. Background technique [0002] Connecting sleeves are commonly used fasteners or connectors in the engineering field, such as equipment installation, steel bar docking, etc. Some of them are fastened in place at one time and do not need to be removed, while some are connected through connecting sleeves and worry about loosening, so they have to be welded ; Some moving equipment is shaken off after being tightened to cause safety accidents, etc. The use of such locknuts or connecting sleeves plays a very good role in connection and fastening. [0003] In engineering fields such as tunnels in underground engineering or roadway bolting in mines, super-long bolts are often encountered, and the space of tunnels or roadways is limited. At this time, the bolts must be connected. The strength of the anchor ro...
