Description
Technical field
The present invention relates to a kind of quick-detachable locks.
Background technique
Lid, watch window etc. is provided in some equipment to need through the normally open window with closure, to check machine
The state of running.The windows such as existing lid, watch window mostly use greatly threaded connection, but be threadedly coupled dismounting get up it is time-consuming
Arduously, it requires various mechanisms to operate time saving, laborsaving feature with today's society not being inconsistent completely.Quick-detachable lock is a kind of with quickly pass
The quick dispatch mechanism close, quickly opened is very suitable for needing on high-speed aircraft or high speed motor car through normally open and close
The occasion of conjunction.Quick-detachable lock not only it is simple, convenient flexibly, it is safe and reliable, convenient for handling, but also production effect can be greatly improved
Rate.And in the privileged sites of some states often in high-frequency vibration, then need a kind of quick-detachable lock of antivibration.
The Chinese utility model patent that Authorization Notice No. is CN203822793U, authorized announcement date is 2014.09.10 discloses
A kind of quick-detachable lock, this quick-detachable lock include pin, mandril, direct acting sliding block, lock set, fixing sleeve and resetting apparatus.The quick-release
The push rod that is provided centrally in pin is locked, wedge-shaped square is provided with below pin, direct acting sliding block is provided in lock set, direct acting is sliding
It is provided with the groove with wedge-shaped square rotation stop cooperation above block, vertical with wedge shape square rectangular open is provided with above lock tube seat
Mouthful, block is carried out to wedge-shaped square, the wedge-shaped square rotation stop being arranged below the groove and pin of the setting of sliding block top cooperates, thus
Realize the circumferential locking to pin.When unlock, push rod can push direct acting sliding block to act, under the groove and pin above sliding block
The wedge-shaped square being just arranged is detached from, and relieves the locking between sliding block and pin in circumferential direction, rotated pin makes wedge-shaped square and side
Shape opening direction is identical, so as to deviate from from opening.The ability that above-mentioned quick-detachable lock has certain antivibration locking.
In the prior art there are also a kind of quick-detachable lock, the form that pinning and lock are locked using lock pin and sliding slot, this
Kind quick-detachable lock is respectively corresponded on lock and pin configured with sliding slot and lock pin, and lock pin, which slides into, carries out locking in sliding slot.But this
Kind uses lock pin and the quick-detachable lock of sliding slot form that can not but use Authorization Notice No. for the Chinese utility model of CN203822793U
It is locking that form disclosed in patent carries out antivibration.
Summary of the invention
The purpose of the present invention is to provide a kind of quick-detachable locks, fast in the form of solution is in the prior art using lock pin with sliding slot
The locking problem of antivibration can not be carried out by unloading lock.
To achieve the above object, the technical solution of quick-detachable lock of the invention is:
Quick-detachable lock, including pinning and lock, lock have the inner cavity being inserted into for pinning, are equipped in the pinning axially living along pinning
The form that the mandril of dynamic setting, the pinning and lock are locked using lock pin and sliding slot, in the inner cavity cavity wall of the lock
Lock pin equipped with the arrangement that overhangs, the pinning are equipped with the sliding slot being adapted to lock pin, and the sliding slot has to be opened for what lock pin entered
The locking end at mouth end and separate open end；It is additionally provided with what axially extending along pinning and with sliding slot locking end communicated in the pinning

Fixed connection or backing pin and mandril split settings and Stop structure along backing pin axial direction block is equipped between mandril, the gear
It sells and enters the lock pin block that extending direction in sliding slot and along the chute will be in lockup state with stop section on active strokes
In the locking position of locking end, also has and act with mandril or exited out of sliding slot under the pushing tow of Stop structure to discharge the lock
The locking releasing position of pin；It is equipped with close to the side of lock for making backing pin court to backing pin or mandril application in the pinning in backing pin
The elastic top selection structure of the active force moved to locking position.
The beneficial effects of the present invention are: being provided with the sliding slot for lock pin sliding on pinning, sliding slot has far from opening
Locking end, while being additionally provided on pinning and by mandril pushing tow and the backing pin in sliding slot can be can extend into, when locking bar is located at locking
When end, the stop section of backing pin is protruded into sliding slot to lock pin block, and backing pin is in locking position at this time, using pushing up after tool pushing tow mandril
Bar drives backing pin to skid off sliding slot, and lock pin can be skidded off by sliding slot opening along the chute, and backing pin is located at anti-releasable lock position at this time.This
Lock pin is locked at the locking end of sliding slot by setting backing pin by invention, and backing pin is maintained at locking by elastic top selection structure
Position, makes sliding slot and the quick-detachable lock of lock pin form also be provided with the locking ability of antivibration, even if under the occasion of high-frequency vibration, backing pin
Also it is not easy to completely disengage sliding slot releasing to the locking of locking bar, ensure that the stability that quick-detachable lock uses, increase the suitable of quick-detachable lock
Use range.
Further, the backing pin and mandril split settings are connected on the stop section of backing pin and to radially extend along pin
Pushing part, pushing part form the Stop structure.Backing pin and mandril split settings are more convenient for manufacturing.
Further, the lock pin and sliding slot circumferentially have at two along quick-detachable lock, and also correspondence is set the backing pin slideway
It is equipped at two, the backing pin is U-shaped, the linkage section including being located at two sections of parallel-segments parallel to each other and connection parallel-segment, connection
For section between mandril and elastic top selection structure, linkage section constitutes the pushing part, and parallel-segment constitutes the stop section.Locking bar is set
Two are set, making pinning and lock, more evenly, and backing pin is arranged between mandril and elastic top selection structure also just stress in locking
In installation.
Further, the mandril is towards being provided with the holding tank for accommodating the pushing part of backing pin on one end end face of lock.
After the pushing part that holding tank accommodates backing pin is arranged, elastic top selection structure is capable of the end face of direct pushing tow mandril, mandril face area
Larger, pushing tow is more stable.
Further, the lock pin is screw-type, and the side wall of lock is equipped with the threaded hole screwed in for lock pin, lock pin
End is equipped with the sliding slot cooperation section being adapted to sliding slot.By the removable production system being mounted in lock convenient for lock and lock pin of lock pin
Make.
