Description

Insert locking nut for automobile engine cabin

Technical Field

The utility model relates to an automobile manufacturing technical field, especially an inserts lock nut for automobile engine storehouse.

Background

With the development of the automobile industry, an insert nut is required for an automobile engine compartment, and the insert nut is a product which is formed by embedding an insert with internal threads and knurling or other patterns on the outer portion in plastic or other alloy products and forming effective threads on a main product.

The existing non-metal insert nut has good protection effect on the threads of a counterpart, but is not suitable for high-temperature environment. The metal sheet insert nut achieves the locking purpose only through the embedded thin sheet, and the locking effect is extremely poor. The remaining pressure points lock the nut, causing significant damage to the threads of the counterpart.

For example, the chinese utility model patent No. 201921570895.7 discloses a non-metal insert lock nut, which comprises a nut body, the nut body is provided with a connecting hole which penetrates through the nut body along the axial direction of the nut body, the inner wall surface of one end of the connecting hole is provided with a threaded part, the inner wall surface of the other end is embedded with a non-metal insert, the inner wall surface of the non-metal insert is provided with a plurality of protruding thorn-shaped objects which are sequentially arranged along the circumferential direction of the non-metal insert, and arranged in the entire circumferential direction of the inner wall surface of the non-metal insert, and each of the spines extends in the axial direction of the non-metal insert, one end of each thorn-shaped object extends to one end surface of the non-metal insert, the other end of each thorn-shaped object extends to the other end surface of the non-metal insert, the inclined direction of the thorn-shaped object is consistent with the thread turning direction of the thread part of the nut body.

Although the insert locking nut is used for preventing looseness or connection failure between the nonmetal insert locking nut and an external piece, the insert locking nut is not suitable for a high-temperature environment in the using process and is not convenient and fast to use.

Disclosure of Invention

The utility model discloses the technical problem that needs to solve provides an inserts lock nut, uses this kind of inserts lock nut can be high temperature resistant, do not hinder adversary's piece screw thread, better locking performance.

The utility model provides a technical scheme of above-mentioned technical problem is: the utility model provides an inserts lock nut for automobile engine storehouse, includes the lock nut body, the lock nut body includes lock nut, be equipped with the internal thread in the lock nut, lock nut is last to be connected with inserts portion, be equipped with the inserts in the inserts portion, the internal diameter of inserts equals internal thread pitch, inserts thickness is an internal thread pitch of detaining, the inserts material is soft metal.

As an optimized technical scheme of the utility model, lock nut is hexagon nut.

As an optimized technical proposal of the utility model, the soft metal is aluminum.

As an optimal technical scheme of the utility model, the internal thread pitch diameter scope is 1.373~63.026mm, detains one the tooth pitch scope is 0.3~6 mm.

Because the utility model discloses a behind such structure, through embedding pure aluminum washer, can reach lock nut high temperature resistant, do not hinder adversary's piece screw thread, better locking performance, it is convenient to use, and the practicality is good.

Drawings

Fig. 1 is a schematic structural view of an insert lock nut for an automobile engine compartment according to the present invention.

Fig. 2 is a cross-sectional view of an insert retaining nut for an automotive engine compartment.

In the figure: 1 is the lock nut body, 2 is lock nut, 3 is the internal thread, 4 is inserts portion, 5 is the inserts.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, the utility model discloses an inserts lock nut for automobile engine storehouse, including lock nut body 1, lock nut body 1 includes lock nut 2, be equipped with internal thread 3 in the lock nut 2, be connected with inserts portion 4 on the lock nut 2, be equipped with inserts 5 in inserts portion 4. The locking nut 2 can resist high temperature, threads of a counterpart and better anti-loosening performance through the insert 5, and is convenient to use and good in practicability;

as shown in fig. 2, the inner diameter of the insert 5 is equal to the pitch diameter of the internal thread 3, the thickness of the insert 5 is one thread pitch of the internal thread 3, the insert 5 manufactured according to the pitch diameter and the thread pitch of the internal thread 3 has better locking performance, can be suitable for high-temperature environment, does not damage the thread of the hand piece, and is convenient to use;

the insert 5 is made of soft metal, and a soft metal washer is embedded in the nut, so that the anti-loosening effect can be achieved.

As shown in fig. 1, the lock nut 2 is a hexagonal nut. The hexagonal nut can be assembled with a common automobile engine cabin, and plays a role in fixing and locking.

As shown in fig. 2, the soft metal is aluminum. The nut is embedded with the pure aluminum washer, so that the anti-loosening effect can be achieved. Because the melting point of pure aluminum is high, the high-temperature performance of the aluminum alloy is much higher than that of a nylon insert; the elastic modulus of the aluminum is 70GPa, the hardness is only 20 percent of that of carbon steel, and compared with nylon, the aluminum has very good locking performance and high practicability.

As shown in FIG. 2, the pitch of the internal thread 3 is in the range of 1.373 to 63.026mm, and the pitch of one thread is in the range of 0.3 to 6 mm. The insert 5 manufactured according to the pitch and the pitch of the internal thread 3 has better locking performance, can be suitable for high-temperature environment, does not damage the thread of the hand piece, and is convenient to use.

The description and applications of the present invention are illustrative and are not intended to limit the scope of the invention to the embodiments described above. Variations and modifications of the embodiments disclosed herein are possible, and practical alternatives to and equivalents of the various components of the embodiments are known to those of ordinary skill in the art.
