Specific implementation mode
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment 1 of the apparatus casing of the utility model, as shown in Figures 1 to 5, apparatus casing include upper interlayer 6
With lower interlayer 7, lower interlayer 7 is equipped with opening, which can be used as observation panel or gathering hole, and the shape of upper interlayer 6 is under
The shape of the opening of interlayer 7 is adapted, the lid of the opening of composition.Upper interlayer 6 and lower interlayer 7 are locked by quick-detachable lock to be connected
Together, quick-detachable lock is a kind of quick-release mechanism for having quick closedown, quickly opening, not only simple, convenient flexible, safety
Reliably, easy to disassemble, and installation effectiveness can be greatly improved.Quick-detachable lock includes lock pin 1 and lock 4, and lock pin 1 is used for upper folder
Layer 6 provides pressing force, and lock 4 coordinates for being connect with lower interlayer 7 to be locked for lock pin 1, and the locking of upper lower interlayer 7 is connected to
Together.
Lock pin 1 includes the bar portion 12 vertically extended, and the upper end of bar portion 12 is equipped with for tightening behaviour for tightening work
The operation portion 11 of work, operation portion 11 is that the frustum cone structure held over stem 12 is arranged in the present embodiment, on the outer end face of round platform
Equipped with the straight slot for tightening operation for " one " word screwdriver, the lower face of round platform is for the upside face pressure with upper interlayer 6
Tight fit provides it pressing force, i.e. the lower face of round platform is constituted for the seal face with 6 compression fit of upper interlayer.Bar portion 12
The annular groove for installing clamp spring is equipped at the position of upper end, clamp spring is mounted in the annular groove thus will be upper with seal face cooperation
Interlayer 6 limits over stem 12, prevents lock pin 1 from falling off from upper interlayer 6.Since 3 size of baffle ring is smaller, for avoid baffle ring 3 from
Pass through in mounting hole in upper interlayer 6, plain washer 2 is set over stem 12,2 size of plain washer is larger, and lock pin 1 can be prevented de-
It falls.The lower end of bar portion 12 is equipped with pre-small post-large locking head 13, and locking head 13 is pre-small post-large taper four in the present embodiment
Prism structure, locking head 13 include four inclined-planes, and the front end on this four inclined-planes is tilted to the radially inner side of lock pin 1, to structure
At the side of cylindricality quadrangular.Four inclined-planes are oppositely arranged two-by-two, and rounding off connects between two neighboring inclined-plane.Four inclined-planes
Two larger inclined-planes of corner angle are to lock inclined-plane 131, and two smaller inclined-planes of corner angle are to unlock inclined-plane 132.
It is locking face to lock inclined-plane 131, and unlock inclined-plane 132 is to solve locking face.13 rear end of locking head extends radially outwardly along lock pin 1,
Two extension table structures are formed, the rear end face of extension table is to support the supporting surface 133 locked for lock 4.
4 global shape of lock is similar to plate nut shape, and the center of lock 4 is equipped with the protrusion extended downwardly, lock
4 centers of seat are additionally provided with the through-hole through lock 4 and protrusion, and through-hole is flat, and size and the shape of locking head 13 are suitable
Match, so that locking head 13 can pass through the through-hole.The lower end of boss is slotted, the extending direction of groove width and flat through-hole
Extending direction is vertical, and the slot bottom of fluting is to support mating surface 43, and support mating surface 43 is used for the supporting surface 133 of locking head 13
Support cooperation, makes quick-detachable lock have certain load ability.
Snap 5 includes the mounting portion and reed connected for lock 4, reed is opposite set there are two, reed has with using
In the winder coordinated with locking head 13, the front end of reed winds to form winder inwardly.Reed is oppositely arranged on flat
The both sides in flat-shaped entire widths direction, so that the winder that locking head 13 circumferentially rotates reed after 90 degree across through-hole can be with lock
The locking inclined-plane 131 top pressure cooperation of tight head 13, makes locking head 13 by upward coupling mechanism force.Pass through lock between snap 5 and lock 4
Spring rivet 42 is fixed, and snap 5 is made to be fixed together with lock 4.Rivet hole 41 is arranged in the both ends of 4 width direction of lock, lock 4
When installation, installation rivet 8 passes through the rivet hole in lower interlayer 7 to be deep into lock 4 and lower interlayer 7 in the mounting hole on lock 4
It is fixed together.
Quick-detachable lock makes folder in use, lock pin 1 links together with upper interlayer 6, lock 4 links together with lower interlayer 7
Layer 6 is aligned with the opening in lower interlayer 7, with screwdriver top pressure lock pin 1, the locking head 13 of lock pin 1 is made to pass through the through-hole of lock 4,
After lock pin 1 is pressed to position downwards, the supporting surface 133 of locking head 13 is concordant with support mating surface, clockwise by screwdriver at this time
90 degree of lock pin is rotated, supporting surface 133 can turn on position corresponding with mating surface is supported, which is locking position,
To coordinate with support mating surface support, the winder of two snaps 5 and two locking 131 top pressure of inclined-plane cooperations, will lock at this time
First 13 are pressed in support mating surface, while the cooperation on winder and locking inclined-plane 131 is also prevented from lock pin and circumferentially rotates, and avoids anticipating
Outer unlock；When unlock, 90 degree of lock pin is circumferentially rotated counterclockwise using screwdriver, make key rotation to lock-bit is solved, at this time locking head
13 supporting surface 133 is detached from the support mating surface of lock 4 to be coordinated, the unlock inclined-plane 132 of the winder and tapered end of two snaps
Top pressure coordinates, and locking head 13 is made to receive the upward elastic pressure on top surface of winder, under the action of elastic pressure on top surface, locking head 13 to
On be manoeuvred into through-hole, so that locking head 13 and lock 4 is thoroughly detached from and coordinate, complete unlock.This quick-detachable lock passes through snap
Winder and the cooperation on locking inclined-plane coupling mechanism force is provided, solve existing quick-detachable lock and only provide locking by cylindrical spring
Quick-detachable lock caused by power locks insecure problem.
