Abstract
A kind of quick-detachable lock with locking functions, by upper lock body and down lock body, formed, by screw, locked spacer, pin, retainer, spring, cone, form upper lock body, by hypocentrum and lock, form down lock body, a side that it is characterized in that the stop tooth of described locked spacer is arcuate structure, and the termination of stop tooth is rounding off.
Description
Technical field
The utility model relates to airplane design, is a kind of quick-detachable lock with locking functions of opening fast or closing for large-scale lid on aircraft.
Background technique
The quick-detachable lock of the locking functions using on aircraft at present consists of screw, block, pin, retainer, cone, lock, spring.When using quick-detachable lock, with special tool, to press after pin, rotary screw is to after tightening, and retainer falls in the locking groove of locked spacer, and pin is upspring, and now quick-detachable lock possesses locking functions.The problem that prior art exists is, quick-detachable lock is after screw tightens, and because retainer is stuck on the stop tooth of locked spacer just, retainer cannot fall in the locking groove of locked spacer pin can not be upspring, and causes the defect that quick-detachable lock cannot be locking.
Summary of the invention
In order to overcome this problem of the locking defect of existing quick-detachable lock, the utility model provides a kind of improved quick-detachable lock, not only has quick-detachment function, and can effectively solve this problem of locking defect.
A kind of quick-detachable lock with locking functions, by upper lock body and down lock body, formed, by screw, locked spacer, pin, retainer, spring, cone, form upper lock body, by hypocentrum and lock, form down lock body, a side that it is characterized in that the stop tooth of described locked spacer is arcuate structure, and the termination of stop tooth is rounding off.
The advantage of technique scheme is: on former lock basis, change locked spacer structural type, the arcuate structure of stop tooth, increased retainer relatively and sliding force and the movement clearance of stop tooth, retainer is slided in the locking groove between stop tooth very smoothly, avoided the catching phenomenon of retainer and locked spacer; Realize anti-loosening function; This quick-detachable lock, when any environment locking, all can guarantee that retainer and lock washer are in locking state, simple in structure, easy to operate.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing explanation

Fig. 2 is stop tooth structural representation
Fig. 3 is the application signal of the utility model quick-detachable lock
Number description: 1. screw, 2. pin, 3. retainer, 4. locked spacer, 5. upper cone, 6. lock, 7. lower cone, 8. spring, 9 stop tooths, 10 upper lock bodies, 11 down lock bodies, 12 lids, 13 Airplane frame beams
Embodiment
Referring to accompanying drawing, the application's the quick-detachable lock with locking functions, by upper lock body 10 and down lock body 11, formed, by screw 1, locked spacer 4, pin 2, retainer 3, spring 5, upper cone 5, form upper lock body 10, by hypocentrum 7 and lock 6, form down lock body 11, one side of each stop tooth 9 of described locked spacer 4 is arcuate structure, and the termination of stop tooth is rounding off, as shown in Figure 2.
The spring 8 of upper lock body is placed in bottom in screw, and the spring the other end contacts with pin 2, and pin 2 inserts screw 1 internal upper part, retainer 3 inserts pin 2 intermediate throughholes, during assembling, screw 1 is a tight fit in to locked spacer 4 inside, upper cone 5 and locked spacer 4 side by side, connect by rivet.Hypocentrum 7 inserts in lock 6 center holes, and hypocentrum 7 forms down lock body with lock 6.
During use, upper lock body 10 is arranged in lid 12; Down lock body 11 is arranged on the beam frame 13 of aircraft, and when lid 12 is closed, retainer 3 moves up and down in screw, after screw and down lock body tighten, retainer is upspring under spring 8 effect, along the arc-shaped edges of the stop tooth 9 of locked spacer 4, slides in draw-in groove, and now quick-detachable lock possesses locking functions.On the contrary, while opening lid 12, first will remove the stop of 4 pairs of retainers 3 of locked spacer, must press pin 2, Compress Spring 8, oppositely screws screw 1, makes to be embedded in pin 2 in screw and retainer 3 and skids off locking groove along the arc-shaped edges of stop tooth, realizes release.
