Based on the above situation, the present utility model provides a chain tensioner which can effectively solve the above problems.

Disclosure of Invention

The utility model aims to provide a chain tensioner. The chain tensioner disclosed by the utility model is simple in structure and convenient to use, and because the positioning block can stretch out and draw back under the action of the elastic piece, the positioning block can retract when a screw falls into a chain, the situation that the chain is blocked is avoided, the failure rate of a motor is reduced, and the production shutdown of a production line is reduced.

The utility model is realized by the following technical scheme:

the utility model provides a chain tensioner, includes mounting box, locating piece and bolt, be equipped with first cavity and second cavity in the mounting box, the bolt extends to in the first cavity from the mounting box outside, just bolt and mounting box threaded connection, the bolt is located first cavity one end and is equipped with the connecting block, the cover is equipped with the elastic component on the connecting block, the elastic component other end and locating piece connection, be equipped with the guide post on the locating piece, the guide post extends to in the second cavity.

Preferably, the mounting box is provided with an oil filling hole, and the oil filling hole is respectively communicated with the first cavity and the second cavity.

Preferably, the mounting box is provided with a bolt positioning hole.

Preferably, the elastic member is a spring.

Preferably, the bolt is in threaded connection with the mounting box.

Compared with the prior art, the utility model has the following advantages:

the chain tensioner disclosed by the utility model is simple in structure and convenient to use, and because the positioning block can stretch out and draw back under the action of the elastic piece, the positioning block can retract when a screw falls into a chain, the situation that the chain is blocked is avoided, the failure rate of a motor is reduced, and the production shutdown of a production line is reduced.

Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present utility model, preferred embodiments of the present utility model will be described below with reference to specific examples, but it should be understood that the drawings are for illustrative purposes only and should not be construed as limiting the present patent; for the purpose of better illustrating the embodiments, certain elements of the drawings may be omitted, enlarged or reduced and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationship depicted in the drawings is for illustrative purposes only and is not to be construed as limiting the present patent.

Example 1:

as shown in fig. 1 to 2, the utility model provides a chain tensioner, which comprises a mounting box 1, a positioning block 2 and a bolt 3, wherein a first cavity 11 and a second cavity 12 are arranged in the mounting box 1, the bolt 3 extends into the first cavity 11 from the outer side of the mounting box 1, a connecting block 31 is arranged at one end of the bolt 3 positioned in the first cavity 11, an elastic piece 4 is sleeved on the connecting block 31, the other end of the elastic piece 4 is connected with the positioning block 2, a guide column 21 is arranged on the positioning block 2, and the guide column 21 extends into the second cavity 12.

Example 2:

Further, in another embodiment, the mounting box 1 is provided with an oil filling hole 13, and the oil filling hole 13 is respectively communicated with the first cavity 11 and the second cavity 12.

The oil filling hole 13 can be used for filling lubricating oil into the first cavity 11 and the second cavity 12, so that the smooth movement of the guide post 21, the elastic piece 4 and other parts is ensured.

Further, in another embodiment, the mounting box 1 is provided with a bolt positioning hole 14.

The mounting box 1 can be fixed in the device by bolts 3 by providing bolt positioning holes 14.

Further, in another embodiment, the elastic member 4 is a spring.

Further, in another embodiment, the bolt 3 is screwed with the mounting box 1.

Since the bolt is screwed with the mounting box 1, the elastic strength of the spring can be adjusted by adjusting the position of the bolt.

The working principle of one embodiment of the utility model is as follows:

a positioning block 2 is fixed at a chain shaft, when the chain shaft is influenced by a screw to move, the positioning block 2 also retracts under the action of a spring, the original chain shaft is fixed and cannot be adjusted, and once the screw falls into the chain shaft, the situation that the screw is blocked possibly occurs.

The chain tensioner of the present utility model can be easily manufactured or used by those skilled in the art from the description of the present utility model and the accompanying drawings, and can produce the positive effects described in the present utility model.
