Description

Locking structure

Technical Field

The utility model belongs to the technical field of the rotatory technique of locking part and specifically relates to a locking structure is related to.

Background

Because current locking structure is spacing with the mode of plug bolt hand-hole more, causes the shortcoming that spacing angle is few.

Disclosure of Invention

In order to overcome the defects existing in the prior art, the utility model provides a locking structure which is simple and convenient to operate and has a better locking effect.

The utility model provides a technical scheme that its technical problem adopted is:

a locking structure comprises a limiting seat, a limiting sliding block, a spring, a key seat and a key for pushing the limiting sliding block to move, wherein the limiting seat and the key seat are fixed through rivets, the limiting sliding block and the spring are arranged in a cavity formed by buckling the limiting seat and the key seat, the limiting sliding block is annular, the limiting seat and the key seat are respectively provided with a wave-shaped groove with the same size on inner circumferential folds of a buckling cavity, the outer wall of the circumference of the limiting sliding block is provided with a wave-shaped bulge meshed with the wave-shaped groove, the thickness of the limiting sliding block is slightly smaller than the buckling cavity depth of the limiting seat, and meanwhile, the thickness of the limiting sliding block is far larger than the buckling cavity depth; the limiting sliding block and the spring are sleeved outside the rivet, one end of the spring is connected with the limiting seat, and the other end of the spring is connected with the limiting sliding block;

the key is arranged on the key seat, more than two claws are arranged on the key, holes corresponding to the claws are arranged on the key seat, the number of the holes is the same as that of the claws, the holes on the key seat are communicated with a cavity buckled with the limiting seat and the key seat, and the claws on the key penetrate through the holes on the key seat and then abut against the limiting slide block;

when the key is not pressed down, the limiting slide block is tightly pressed against the buckling inner wall of the key base under the acting force of the spring, and at the moment, the wave-shaped bulge on the circumferential outer wall of the limiting slide block is simultaneously meshed with the wave-shaped groove on the circumferential inner wall of the key base and the wave-shaped groove on the circumferential inner wall of the limiting base; when the key is pressed down, the claw on the key pushes the limiting sliding block and the compression spring to slide into the buckling cavity depth of the limiting seat and separate from the wavy groove of the key seat, so that the constraint is removed, and the limiting seat and the key seat can rotate freely.

Furthermore, four claws are arranged on the key, and four holes are arranged on the key seat.

Still further, be equipped with the adapter sleeve who is used for connecting spare part on spacing seat and the key seat respectively, two adapter sleeve's mouth of pipe orientation is different, is equipped with certain contained angle between two adapter sleeve promptly, and two adapter sleeves are used for connecting other two parts, and the adapter sleeve on the key seat is used for connecting the frame riser for example, and the adapter sleeve on the key seat is used for connecting the handrail pipe, realizes that the handrail pipe is rotatable or fold up and connect.

The beneficial effects of the utility model are that: simple operation and good locking effect.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 7, a locking structure is composed of a key 1, a key base 2, a limiting slide block 3, a spring 4, a limiting base 5 and a rivet 6, as shown in fig. 1. The limiting slide block 3 and the spring 4 are arranged in a cavity formed by buckling the limiting seat 5 and the key seat 2 and are fixed through the rivet 6. A key 1 which can push a limit slide block 3 to move is arranged at the outer part of the key base 2 through four holes on the key base, and the key 1 is shown in figure 4. Because the limiting seat 5 and the key seat 2 are provided with the wave-shaped grooves with the same size on the inner circumferential wall of the buckling cavity, the outer circumferential wall of the limiting slide block 3 is also provided with the wave-shaped protrusions engaged with the limiting slide block, and the thickness of the limiting slide block 3 is slightly smaller than the buckling cavity depth of the limiting seat 5 and is far larger than the buckling cavity depth of the key seat 2. When the key 1 is not pressed, the limiting slide block 3 is tightly pressed against the buckling inner wall of the key base 2 under the action of the spring 4, see fig. 5. The wave-shaped bulges on the circumferential outer wall of the limiting slide block 3 are meshed with the wave-shaped grooves on the circumferential inner wall of the key base 2, and simultaneously meshed with the wave-shaped grooves on the circumferential inner wall of the limiting base 5, so that the limiting base 5 and the key base 2 cannot rotate. When the key 1 is pressed, the four claws of the key penetrate through holes on the buckling inner wall of the key base 2 to push the limiting slide block 3 to compress the spring 4 to slide into the buckling cavity depth of the limiting base 5, so that the limiting slide block is separated from the wave-shaped groove of the key base 2, and the constraint is removed to enable the limiting base 5 and the key base 2 to freely rotate.
