Description

A kind of locking device
Technical field
The utility model relates to employed locking device in a kind of safety device, belongs to a kind of locking device.
Background technology
At present, all need to be provided with safety prevention measure in a lot of running devices,, the device of locking need be arranged all such as, hanging device in the door and window of passenger's vehicle, the seat of recreational machine, the building operations etc.Existing locking device generally is to adopt the anti-lockset of usurping, and locks by the dead bolt in the lockset, because dead bolt can not be located, will lock because of carelessness in use, needs to open, and uses inconvenient.
Summary of the invention
In order to overcome disadvantages of background technology, the utility model provides a kind of locking device, has solved mainly that dead bolt in the existing lockset can not be located, inconvenient problem with use, and this locking device structure is simple, can locate automatically, have characteristics simple in structure and easy to use.
The technical solution of the utility model is: a kind of locking device mainly is made up of locking plate, lock housing, lock core, clutch, stage clip, guide pin bushing and stifle, lock core, clutch, stage clip and guide pin bushing are installed in the lock housing successively, guide pin bushing is spacing by the stifle that is connected the lock housing end, the other end of lock core connects locking plate, lock core can together rotate in company with locking plate, lock core is provided with and the extraneous central through hole that communicates, and described central through hole is corresponding with clutch; Clutch is provided with tenon, and lock core is provided with straight trough and " V " type groove, and tenon can enter straight trough and " V " type groove during rotary locking cylinder under the effect of stage clip.
Described straight trough and " V " type groove are radially vertical mutually along lock core.
Be provided with push rod in the central through hole on the described lock core, lock core is provided with counterbore, and nut is installed on the push rod, makes push rod limited at the counterbore place.
Described lock housing is provided with draw-in groove, and the guide pin bushing outer wall is provided with lug, and lug is embedded in the draw-in groove; The center of guide pin bushing is provided with square opening, and an end of clutch coincide to be inserted in the guide pin bushing and also can move axially.
The utlity model has following beneficial effect: owing to take such scheme, when non-locking state, tenon on the clutch is in lock core " V " the type groove, " V " type groove plays the role of positioning, this moment under external force can rotational lock core, mainly is to avoid reasons such as vibration, impact to make tenon enter straight trough; When locking, the rotation locking plate, lock core therewith rotates, and the tenon on clutch enters straight trough, and locking plate is locked, can not rotate.During release, insert in the central through hole with special tool, promote clutch and make its straight trough that detaches lock core, clutch is to the latch-release of lock core.The utility model can be located automatically, has characteristics simple in structure and easy to use.
Description of drawings
Accompanying drawing 1 is a structure sectional view of the present utility model.
Accompanying drawing 2 is Fig. 1 three-dimensional exploded views.
1-locking plate among the figure, 2-lock housing, 3-lock core, 4-clutch, 5-stage clip, 6-guide pin bushing, 7-stifle, 8-central through hole, 9-tenon, 10-straight trough, 11-" V " type groove, 12-push rod, 13-counterbore, 14-nut, 15-draw-in groove, 16-lug.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of locking device, mainly form by locking plate 1, lock housing 2, lock core 3, clutch 4, stage clip 5, guide pin bushing 6 and stifle 7, lock core 3, clutch 4, stage clip 5 and guide pin bushing 6 are installed in the lock housing 2 successively, guide pin bushing 6 is spacing by the stifle 7 that is connected lock housing 2 ends, and the other end of lock core 3 connects locking plate 1, and lock core 3 can together rotate in company with locking plate 1, lock core 3 is provided with and the extraneous central through hole 8 that communicates, and described central through hole 8 is corresponding with clutch 4; Clutch 4 is provided with tenon 9, and lock core 3 is provided with straight trough 10 and " V " type groove 11, and tenon 9 can enter straight trough 10 and " V " type groove 11 during rotary locking cylinder 3 under the effect of stage clip 5.When non-locking state, the tenon 9 on the clutch 4 is in " V " type groove 11 of lock core 3, and " V " type groove 11 plays the role of positioning, and this moment under external force can rotational lock core 3, mainly is to avoid reasons such as vibration, impact to make tenon 9 enter straight trough 10; When locking, rotation locking plate 1, lock core 3 therewith rotates, and the tenon 9 on clutch 4 enters straight trough 10, and locking plate 1 is locked, can not rotate.During release, insert in the central through hole 8, promote clutch 4 and make its straight trough that detaches lock core 3 10, the latch-release of 4 pairs of lock cores 3 of clutch with special tool.
