Description
Technical field
The utility model relates to a kind of movable latch, particularly relates to a kind of movable plug device with auto-lock function; Belong to non-standard fastener.
Background technique
As everyone knows, movable latch is the conventional a kind of fastening piece of machinery, is usually made up of latch body, the chain rope that is attached thereto; During use, latch is inserted in pin-and-hole or guide.Although relatively simple for structure, use also very convenient, there is no auto-lock function; When machinery high vibration or when jolting, easy loose or dislocation, reliability is poor.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide a kind of easy to use, reliable self-locking movable bolt device of self-locking property.
To achieve these goals, the utility model by the following technical solutions: it comprises pin bushing, is arranged in the latch body of this pin bushing; The inwall of pin bushing has two guiding grooves offered vertically, the wall of this pin bushing there are two through waist-shaped holes, the median plane of two waist-shaped holes is vertical with the median plane of two guiding grooves, the wall of this pin bushing has the spiral chute that two upper ends are communicated with corresponding guiding groove, lower end is communicated with corresponding waist-shaped hole; Described latch body is by bearing pin, crossing with this bearing pin and be connected as the sliding pin of cross-shaped configuration is formed.
The top of bearing pin is fixed with handle.
Compared with the prior art, the utility model is owing to have employed technique scheme, change traditional latch body into cross-shaped configuration, and on the wall of guide, add two spiral chutes and two waist-shaped holes, therefore by sliding pin and spiral chute and coordinating of waist-shaped hole can effectively avoid bearing pin to loosen, thus self-locking property is improved.The utility model has the advantages such as easy to use, self-locking property good, structure is relatively simple.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view in Fig. 1;
Fig. 3 is the structural representation of the utility model pin bushing;
Fig. 4 is the A-A sectional view in Fig. 3;
Fig. 5 is the plan view of Fig. 3.
In figure: handle 1, pin bushing 2, waist-shaped hole 3, bearing pin 4, sliding pin 5, spiral chute 6, guiding groove 7.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1 ~ 5, the utility model is made up of pin bushing 2, latch body suitable with it.The inwall of pin bushing 2 has two guiding grooves 7 offered vertically, the wall of this pin bushing there are two through waist-shaped holes 3, the median plane of two waist-shaped holes 3 is vertical with the median plane of two guiding grooves 7, the wall of this pin bushing has the spiral chute 6 that two upper ends are communicated with corresponding guiding groove 7, lower end is communicated with corresponding waist-shaped hole 3; Described latch body is made up of bearing pin 4, and the sliding pin 5 being linked as cross-shaped configuration crossing with this bearing pin.
For the ease of taking out latch, the top of bearing pin 4 is fixed with handle 1.
During use, inserted by bearing pin 4 in pin bushing 2, sliding pin 5 can be transferred landing along guiding groove 7, spiral chute 6 dextrorotation and snap in waist-shaped hole 3 locked; During unblock, only need upwards and rotate counterclockwise handle 1 latch body to be taken out.
Claims (2)
