Description

Anti-loosening embedded thread sleeve

Technical Field

The utility model relates to a fastener technical field especially relates to a locking thread bush of inlaying that takes off.

Background

The fastener is used for connecting between mechanical parts and the indispensable part of device fixed, and the threaded bush of inlaying all will be applied to in many aspects in the automobile assembly field, and it is embedded in the automobile working of plastics inner chamber usually to block, then treats that the connecting piece utilizes bolt and the threaded bush of inlaying to connect and realize fixing.

The problem that prior art exists lies in, inlays the working of plastics inner chamber of screw thread cover and integrated into one piece in the car and links to each other through the joint, can have to deviate from or the condition such as rotate appears in the plastic sheath inner chamber, and then leads to treating that the connecting piece is fixed unstable or when the bolt with inlay screw thread cover accordant connection, both rotate simultaneously, are difficult to change over the bolt into, therefore these problems need to improve urgently.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned technique, provide a locking pine takes off and inlays the thread bush, can firmly imbed in the automobile working of plastics inner chamber, the pine takes off and the pivoted problem can not appear.

In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:

the utility model provides an anti-loosening embedded thread sleeve, includes columniform body, its characterized in that, the slotted hole that can be connected with bolt fit is seted up along the axial in the one end center of body, be equipped with the joint ring on the outer wall of body, the joint ring is fillet rectangle structure, just the both sides of joint ring are equipped with the arch of cockscomb structure along length direction.

The utility model discloses a further improvement lies in, the joint ring is equipped with at least two.

The utility model discloses a further improvement lies in, slotted hole inner wall processing have with bolt external screw-thread fit's internal thread, be convenient for the body be connected with the bolt.

The utility model discloses a further improvement lies in, the tank bottom of slotted hole is equipped with the one deck rubber layer, and the rubber layer has elasticity, receives the effect of elasticity behind the bolt extrusion rubber layer for the thread of bolt tightly pastes tightly with the thread of slotted hole, improves the joint strength of bolt and body.

The utility model discloses a further improvement lies in, is relative with the slotted hole the other end of body is the toper structure, the inlaying of the body of being convenient for.

The utility model has the advantages that: the utility model discloses a set up the joint ring of rounded rectangle structure on the body, cooperate the arch of cockscomb structure simultaneously, can guarantee that the body can firmly be inlayed in automobile plastic spare inner chamber, difficult pine takes off and can not produce in bolted connection in-process and rotate, the utility model discloses simple structure, convenient to use has fine popularization and application effect.

Drawings

Fig. 1 is a front view of the present invention.

Fig. 2 is a bottom view of the present invention.

In the figure: the rubber layer comprises a body 1, a slot hole 2, a clamping ring 3, a protrusion 4 and a rubber layer 5.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1-2, an anti-loose inlaid thread sleeve comprises a cylindrical body 1, a slotted hole 2 which can be connected with a bolt in a matching way is axially arranged at the center of one end of the body 1, a clamping ring 3 is arranged on the outer wall of the body 1, the clamping ring 3 is of a round-angle rectangular structure, and sawtoothed protrusions 4 are arranged on two sides of the clamping ring 3 along the length direction.

In particular, at least two snap rings 3 are provided.

Specifically, the inner wall of the slot 2 is provided with an internal thread matched with the external thread of the bolt, so that the body 1 can be conveniently connected with the bolt. Alternatively, the slot 2 may not be internally threaded, but in this case, the inner diameter of the slot 2 should be slightly smaller than the outer diameter of the bolt, so that when the bolt is rotated into the slot 2 by an external force, the inner wall of the slot 2 is automatically drilled into the internal thread matching with the bolt, and the connection is more secure.

Specifically, the bottom of the slot hole 2 is provided with a rubber layer 5, the rubber layer 5 has elasticity, and the bolt is pressed on the rubber layer 5 and then is acted by the elasticity, so that the thread of the bolt is tightly attached to the thread of the slot hole 2, and the connection strength of the bolt and the body 1 is improved.

Specifically, the other end of the body 1 opposite to the slot 2 is a conical structure, which is convenient for the body 1 to be embedded.

The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
