Abstract
The utility model belongs to the technical field of machine design, a automatic locking latch structure of easy dismounting is related to. The utility model discloses a pull ring, lid, casing, pressure spring, center pin, ball, the center pin passes through pressure spring and casing and the lid is connected and can be followed the guide hole endwise slip on the casing, the lid through the fix with screw on the casing, it is continuous with the center pin that the pull ring passes the terminal round hole of center pin. The utility model discloses a pretightning force of pressure spring makes the steel ball card on the bolt go into in the annular of pinhole. Under the quick operating mode of dismantling and installing of needs, can guarantee reliable auto -lock. The utility model provides an inconvenient problem of locking latch quick assembly disassembly, realize the automatic locking of bolt, its simple structure is reliable, the dismouting of being convenient for.
Description
Technical field
This utility model belongs to technical field of mechanical design, relates to the auto lock latch structure of a kind of easy accessibility.
Background technology
The structure that the most common latch structure typically uses straight pin to coordinate with pin-and-hole, general pin lock clamping method is fixed locking, does not has automatic fastening function, and is not easy to dismounting and installs.In needs repeated disassembled and assembled and cause a lot of inconvenience in the case of needing fast assembling-disassembling, dismounting work is complicated.
Utility model content
The purpose of this utility model: propose a kind of easy accessibility, simple in construction, auto lock latch structure that reliability is high.
The technical solution of the utility model: a kind of auto lock latch structure, it includes covering 2, housing 3, stage clip 4, central shaft 5, ball 6, wherein, central shaft 5 is arranged in the housing 3 of hollow, central shaft 5 termination is bullet, the hole, location of housing 3 head placed by ball 6, end face contacts through hole, location with base inner annular groove, bottom surface and bullet upper surface, stage clip 4 is socketed in central shaft 5 stage casing, lid 2 is fixed on housing 3, and compresses stage clip 4, and central shaft 5 afterbody stretches out housing 3 outer end as plug end.
It is provided with on central shaft 5 afterbody for the draw ring 1 of drawing or stay cord or pull bar.
Lid 2 is fixed on housing 3 by helicitic texture or welding manner.
Advantage of the present utility model: this utility model makes the steel ball on latch snap in the annular groove of pin-and-hole by the pretightning force of stage clip.Under needing the operating mode of fast quick-detach and installation, it is ensured that self-locking reliably.The problem that this utility model solves the inconvenience of locking latch fast assembling-disassembling, it is achieved the auto lock of latch, it is simple and reliable for structure, be easy to dismounting.
Accompanying drawing illustrates:
Fig. 1 is the sectional view of a kind of detailed description of the invention of the auto lock latch structure of this utility model easy accessibility；
Wherein, 1-draw ring, 2-lid, 3-housing, 4-stage clip, 5-central shaft, 6-ball.
Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Seeing Fig. 1, it is a kind of detailed description of the invention of auto lock latch structure of this utility model easy accessibility.Described auto lock latch structure includes covering 2, housing 3, stage clip 4, central shaft 5, ball 6.Wherein, central shaft 5 is arranged in the housing 3 of hollow, and central shaft 5 termination is bullet, and the hole, location of housing head placed by ball 6, and end face contacts through hole, location with base inner annular groove, and bottom surface is through hole, location and bullet upper surface.Described stage clip 4 is socketed in central shaft 5 stage casing, and lid 2 is fixed on housing 3, and compresses stage clip 4, thus promotes central shaft 5 that the ball 6 on bullet is pressed into support inner loop groove, it is achieved locking.
Described central shaft 5 afterbody stretches out as plug end and is provided with on housing 3 outer end, and central shaft 5 afterbody for the draw ring 1 of drawing or stay cord or pull bar, and to facilitate dismounting, in present embodiment, central shaft 5 is aft mounted is draw ring 1.
Lid 2 is fixed on housing 3 by helicitic texture or welding manner.
During the work of this utility model auto lock latch structure, latch first inserting pin-and-hole, the compression elasticity of stage clip 4 makes central shaft 5 conical surface hold out against ball 6, and ball 6 part highlights housing 3 annular groove falling in pin-and-hole, latch auto lock.When needing dismounting, pull draw ring 1 can drive central shaft 5 compression press spring 4, the pressure of ball 6 not acceptor center axle 5 conical surface and squeezed push back in housing 3, thus terminate the locking between latch and support so that latch structure entirety can easily be extracted from pin-and-hole.
