Abstract
The invention discloses an anti-disengaging structure for a bolt. The anti-disengaging structure comprises a shaft, an opening ring circle and the bolt which penetrates and is inserted in the shaft in the radial direction. The shaft is sleeved with the opening ring circle, and the opening end of the opening ring circle is inserted in the end, stretching out of the shaft, of the bolt in the radial direction. The anti-disengaging structure is further characterized in that the opening ring circle is inserted in the other end, stretching out of the shaft, of the bolt; and the opening ring circle is a spring steel wire. By means of the anti-disengaging structure, the bolt can be effectively prevented from disengaging, and reliable limiting of the bolt is achieved.
Description
Technical field
The present invention relates to a kind of axial limit structure, particularly relate to a kind of latch structure.
Background technology
In order to make on axle, the part of suit is at axle upper limit, and having a kind of mode is to use latch structure.Existing latch structure has two ways, and a kind of is that latch is inserted radially on axle on the axle of suit part end, and is fixedly connected on axle by interference fit, and another kind is that latch extends radially through suit part, axle on axle, and connects by interference fit is fixing.Both modes can realize being set with on axle spacing on axle of part, but has the disadvantage that latch fixes connection by interference fit, life-time service or may be loosened by external force, come off, it is impossible to realizes the most spacing.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of to realize the latch anti-drop structure that latch is the most spacing.
The present invention is achieved through the following technical solutions technical goal.
Latch anti-drop structure, including axle, extends radially through and is inserted into the latch on axle；It thes improvement is that: also include opening ring；Described split ring snare is contained on axle, and the opening of opening ring is inserted radially into one end of latch projecting shaft.
In said structure, described opening ring inserts the other end of latch projecting shaft.
In said structure, described opening ring is spring steel wire.
The present invention compared with prior art, has the positive effect that:
1, arranging opening ring, split ring snare is contained on axle, and the opening of opening ring is inserted radially into one end of latch projecting shaft, such that make latch occur loosening phenomenon, the opening ring being sleeved on axle can stop the movement of latch, thus stop coming off of latch.
2, opening ring inserts the other end of latch projecting shaft, can stop the movement of latch at latch two ends, be further ensured that spacing reliable.
3, opening ring is spring steel wire, and spring steel wire has preferable structural strength and elasticity, plays more preferable slip-off preventing effect.
