Description
Technical field
The utility model belongs to the technology of quick-expansion locking.
Background technique
The utility model is mainly used in field operations catering facility, under making instruction condition in the wild, under equipment needs rapid deployment to remove the environment of receipts.The Locking Device bought on the market is all exposed and embedded; Volume is large, weight is large; Locking is insecure, cannot meet special design needs.
Model utility content
The purpose of this utility model just in order to overcome above-mentioned existing Locking Device cannot meet special designing requirement and provide a kind of simply and easily can quick-expansion locking, the telescopic Locking Device of the advantage that other Locking Devices have can be reached.
The purpose of this utility model is achieved by the following technical solution.
A kind of telescopic Locking Device, the utility model is characterised in that, should be connected and composed by press head, helical teeth guide rail sleeve, flexible dead bolt, Compress Spring, lock sleeve; Wherein:
Press head is a circular cylinder, is fixed with latch at this circular cylinder lower loop circular cylinder, is provided with connecting pin in center, this circular cylinder bottom;
Helical teeth guide rail sleeve is a sleeve and the flange being connected to sleeve ends, is equipped with the draw-in groove embedded for latch at sleeve lining;
Flexible dead bolt comprises a circular cylinder and ring and is located at step on circular cylinder, and step is equipped with the moving tooth of band oblique cutting head;
Compress Spring is set on the circular cylinder of flexible dead bolt;
Lock sleeve is a circular sleeve;
Linkage structure is: the flange end of helical teeth guide rail sleeve is inserted in the latch of press head, and latch coordinates with draw-in groove; Flexible lock bolt sleeve is located in helical teeth guide rail sleeve, and makes the moving tooth of band oblique cutting head and the helical teeth corresponding matching of helical teeth guide rail sleeve inwall; The step on circular cylinder is withstood in one end of Compress Spring, and the other end withstands the tail end of lock sleeve; Lock sleeve head end is connected with the bush whorl of helical teeth guide rail sleeve, and the perforate of tail end allows the circular cylinder part of flexible dead bolt stretch out.
This device is applicable to the quick locking of rotating machinery, the quick mounting location etc. of project equipment, for first effective this product of head it off adopts teeth cells slideway type telescopic spring linking mechanism, can fast and effectively by the article fix in position that will fix or unclamp immediately; Secondly get loose for preventing, what this device adopted in guide rail sleeve is ratchet structure.
The beneficial effects of the utility model it is possible to the quick locking of the mode of point contact type and the advantage loosened.
Content of the present utility model is set forth further below in conjunction with attached Example.

Embodiment
See Fig. 1-Fig. 6, a kind of telescopic Locking Device, the utility model is characterised in that, is connected and composed by press head 1, helical teeth guide rail sleeve 2, flexible dead bolt 3, Compress Spring 4, lock sleeve 5; Wherein:
Press head 1 is a circular cylinder, is fixed with latch 1.1 at this circular cylinder lower loop circular cylinder, is provided with connecting pin 1.2 in center, this circular cylinder bottom;
Helical teeth guide rail sleeve 2 is a sleeve 2.1 and the flange 2.2 being connected to sleeve ends, is equipped with the draw-in groove 2.3 embedded for latch 1.1 at sleeve 2.1 inwall;
Flexible dead bolt 3 comprises a circular cylinder 3.1 and ring and is located at step 3.3 on circular cylinder 3.1, and step 3.3 is equipped with the moving tooth 3.2 of band oblique cutting head;
Compress Spring 4 is set on the circular cylinder 3.1 of flexible dead bolt 3;
Lock sleeve 5 is a circular sleeve;
Linkage structure is: flange 2.2 end of helical teeth guide rail sleeve 2 is inserted in the latch 1.1 of press head 1, and latch 1.1 coordinates with draw-in groove 2.3; Flexible dead bolt 3 is set in helical teeth guide rail sleeve 2, and makes the moving tooth 3.2 of band oblique cutting head and the helical teeth corresponding matching of helical teeth guide rail sleeve 2 inwall; The step 3.3 on circular cylinder 3.1 is withstood in one end of Compress Spring 4, and the other end withstands the tail end of lock sleeve 5; Lock sleeve 5 head end is threaded with the sleeve 2.1 of helical teeth guide rail sleeve 2, and the perforate of tail end allows circular cylinder 3.1 part of flexible dead bolt 3 stretch out.
The job step of the utility model device is divided into two states, and after pressing, dead bolt stretches out locking and the rear dead bolt income of pressing.
Complete above two actions to have come primarily of ratchet structure, on press head 1 and press head 1 time, helical teeth guide rail bucket has two sections, and A section is that press head is provided with 8 slide blocks, slippage on the guide rail simultaneously in helical teeth guide rail bucket; B section is the step of ratchet structure motion, flexible dead bolt is furnished with the past polyslip in eight helical teeth guide-track grooves of four helical teeth slide blocks on helical teeth guide rail bucket inwall.
Original state, due to the effect of helical teeth guide rail bucket upper rail, it is the beveled top end that slide block on press head withstands four slide block inclined-planes of flexible dead bolt, come downwards to guide rail end along the guide-track groove in helical teeth guide rail sleeve always, the restriction of four slide blocks of flexible dead bolt just getaway groove, rotate 45 ° (under the acting in conjunction of inclined-plane 1 and spring, then there occurs first time owing to there being the restriction of getaway by flexible dead bolt to rotate) along helical teeth guide rail sleeve inclined-plane to the oblique tooth slot position of Fig. 3, complete flexible dead bolt and complete the action that dead bolt stretches out locking; Next press head is touched downwards, press head is slippage downwards again, and pass the interior flexible dead bolt of helical teeth groove being stuck in and having illustrated shown in 4, due to the effect of spring, can be there are second time 45 ° of rotation in flexible dead bolt, until flexible dead bolt and press head to be completed the step that dead bolt takes under the effect of the reverse lifting of spring along the track in helical teeth guide rail sleeve to top.That so goes round and begins again completes flexible circulation step.
