Disclosure of Invention

The utility model aims to solve the defects that in the prior art, workers cannot conveniently recycle expansion bolts, and resources are wasted.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the novel expansion bolt comprises a sleeve, a round block is attached to the inner wall of the sleeve, and a turnover structure is arranged on one side of the sleeve.

Preferably, the turnover structure comprises a rotating rod, the lower parts of the front end surfaces of the two rotating rods are respectively connected with the inner walls of the lower parts of the left side and the right side of the sleeve in a rotating way through pin shafts, and one lower part of each rotating rod is respectively fixedly connected with the left end and the right end of the spring.

Preferably, the top of the round block is fixedly connected with a threaded rod.

Preferably, a vertical block is connected below the outer wall of the threaded rod in a threaded manner, and the lower part of the outer wall of the vertical block is fixedly connected with the upper part of the inner wall of the sleeve.

Preferably, the top of the threaded rod is fixedly connected with a block.

The novel expansion bolt provided by the utility model has the beneficial effects that: through sleeve, circle piece, perpendicular piece, threaded rod, block and flip structure's cooperation for the device can be when using through rotating the block, and the block drives the threaded rod and rotates, and the threaded rod drives circle piece and together moves down, and the circle piece drives the bull stick and rotates, and the bull stick stretches the spring, and then realizes the fixed effect of inflation, when circle piece atress upwards moves, and the spring drives the bull stick and inwards rotates, and then makes and resumes the normal position, is convenient for take out the sleeve, avoids the sleeve to take place to damage, and the staff of being convenient for carries out cyclic utilization to expansion bolts, resources are saved.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

example 1: referring to fig. 1-5: in this embodiment, a novel expansion bolts, including sleeve 1, sleeve 1's inner wall laminating has circle piece 3, circle piece 3's top fixedly connected with threaded rod 5, rotate threaded rod 5, can drive circle piece 3 and move together when threaded rod 5 reciprocates, threaded rod 5's outer wall below threaded connection has perpendicular piece 4, perpendicular piece 4's outer wall below and sleeve 1's inner wall top fixedly connected with block 6 of threaded rod 5, the top processing of block 6 has the cross recess, sleeve 1's one side is equipped with flip structure 2, flip structure 2 is convenient for the staff to expansion bolts to recycle, resources are saved.

The turnover structure 2 comprises a rotating rod 2a1, the lower parts of the front end surfaces of the two rotating rods 2a1 are respectively connected with the inner walls of the lower parts of the left side and the right side of the sleeve 1 through pin shafts, the rotating rod 2a1 can rotate on the inner walls of the lower parts of the left side and the right side of the sleeve 1 when being stressed, one side lower parts of the two rotating rods 2a1 are respectively fixedly connected with the left end and the right end of the spring 2a2, a rotating block 6 drives a threaded rod 5 to rotate, the threaded rod 5 drives a round block 3 to move downwards together, the round block 3 drives the rotating rod 2a1 to rotate, the rotating rod 2a1 stretches the spring 2a, further the expansion fixing effect is achieved, the spring 2a2 drives the rotating rod 2a1 to rotate inwards when the round block 3 is stressed upwards, the sleeve 1 is conveniently taken out, the sleeve 1 is prevented from being damaged, workers can use expansion bolts circularly, and resources are saved.

Working principle:

firstly, insert sleeve 1 in the wall body, rotate block 6, block 6 drives threaded rod 5 rotation, threaded rod 5 drives round piece 3 and together moves downwards, round piece 3 drives bull stick 2a1 rotation, bull stick 2a1 stretches spring 2a2, and then realize the inflation fixed action, when needs take out sleeve 1, reverse rotation block 6, block 6 drive threaded rod 5 rotation, threaded rod 5 drives round piece 3 upwards and removes, spring 2a2 drives bull stick 2a1 inwards and rotates, and then makes and resumes normal position, is convenient for take out sleeve 1.

Example 2: referring to fig. 1-5: in this embodiment, a novel expansion bolt, wherein the turnover structure 2 may further include a bump 2b1, and one end of the bump 2b1 is fixedly connected with one side upper portion of the rotating rod 2a 1.
