Description
Technical field
The present invention relates to tightening technology field of the printed board in cabinet slot, and in particular to a kind of nonstandard printed board is in machine
Quick locking and release in case slot, fastening effect is just can reach without using the operation of screw and other instruments.
Background technology
Nonstandard printed board insertion cabinet slot after, it is necessary to carry out fastening it is locking, to prevent in transportation, due to shaking
The influence of the external force such as dynamic, impact, printed board swings percussion cabinet housing at random, causes printed board to deform and rupture, or make printing
Electric connector between plate and motherboard is released, and causes electric connector contact bad or open circuit.
Fastening of the nonstandard printed board in cabinet slot, existing fastening means is mostly using wedge locking device come real
It is existing, it is indivedual to use screw fastening means.
Wedge locking device is when cabinet slot domestic demand locks printed board, by rotating the spiral shell coaxial with upper and lower wedge type block
Nail, drives removable lower wedge type block, extrudes mobilizable upper wedge type block, makes wedge type block raised, when projection exceedes wedge locking
The substantially planar certain size of device, with being brought into close contact on the inside of cabinet slot, continues rotary screw, upper wedge type block is in cabinet slot
Larger extruding force is produced, so that the printed board fastening linked together;During unblock, screw is reversely rotated, by lower wedge type block
Exit, upper wedge type block does not have after extruding force, just unclamped naturally with slot.Such locking device advantage is that simple in construction, cost is low,
Have the disadvantage that such locking device need to be operated by instrument (bottle opener), the extruding force of generation leans on the feel and experience of operating personnel,
Often there is, upper wedge type block and slot inwall adhesion excessive because extruding, cause printed board not extract, at this moment need to use other stocks
Instrument, stretches into and wedge type block is stirred in slot, is allowed to disengage adhesion state with slot inwall;What is more, screw slide fastener or disconnected
Split, cause printed board not extract, just can only can extract printed board with the method for destroying constitutional detail.In some special feelings
Under condition, scene when needing to extract printed board, is then felt simply helpless without instrument (bottle opener), after instrument is called in, then is wasted big
The time and efforts of amount.
Printed board in slot is fastened using screw, usually printed board bottom is connected by electric connector with motherboard, printed
Then it is connected at the top of making sheet with screw with slot outer face.Such printed board fastening means, advantage be structure letter, cost it is low, shortcoming
It is that such locking device need to be operated by instrument (bottle opener), is only applicable to the printed board of small size;When printing board size is larger
When, the bottom and top of printed board are only secured, printed board middle part seems weak, in transport because vibrating and impacting possible
Can damaged fracture.
The content of the invention
For problem of the prior art and urgent technical need, the invention provides a kind of printed board in cabinet slot
Locking device, it is intended that solving quick locking of the nonstandard printed board in cabinet slot and releasing, coupling mechanism force is controllable, no
Printed board locking can be completed using the operation of screw and instrument and action is released, and shortened the assembling of printed board, safeguarded and detect
Time.
To achieve the above object, according to one aspect of the present invention, the invention discloses a kind of printed board in cabinet slot
Interior locking device, including be symmetrical set and two locking units of structure identical;Locking unit includes locking support, led
To pin, positioning lock shaft, tense bar, sliding-tongue rotating shaft, sliding-tongue and elastic force depression bar;
The locking support is L-shaped elongate body, and the top on the long side of its L-shaped has a journal stirrup with U-lag;
The tension bar is strip, and positioned at the long side of the L-shaped of locking support, the upper end of strip is provided with through hole, strip
Front be provided with countersunk head through hole and slotted hole;
The guide pin is installed in the slotted hole of the tension bar, can only be moved up and down for limiting tension bar;
The positioning lock shaft is a straight pin with the level, concordant with the riveting of locking support L-shaped long side end face, from end face
Back is stretched out;
The sliding-tongue rotating shaft is a straight pin with the level, and the sliding-tongue rotating shaft passes through the countersunk head through hole for tensing bar, and
It is inserted in sliding-tongue and rivets;
The sliding-tongue is the elongate body of two semicircle, and there are 1 manhole and 1 long round tube hole, the circle in front
Through hole installed in the sliding-tongue rotating shaft tensed on bar with riveting, the long round tube hole and positioning lock shaft riveting;
The elastic force depression bar is single pole spring wire, and its one end is connected with tensing the upper end through hole of bar, and intermediate point is placed in lock
In the journal stirrup with U-lag of tight bearing, the other end is used as operating side.
Further, the guide pin is a straight pin with the level, flat with the riveting of locking support L-shaped long side end face
Together, and from end face back stretch out.
Further, the free end of the L-shaped short side of the locking support bends and slotted, and notch is another as elastic force depression bar
The strong point of one intermediate point.
Further, the operating side of the elastic force depression bar is processed as handle shape.
The technique effect of the present invention:
The printed board locking device that the present invention is provided is compared with domestic printed board locking device more common at present, locking
Mode has significant difference.The printed board locking device that the present invention is provided uses linkage, lever form, material shell-shaped deformation three
The different executive mode of kind and principle are locked and unlocking motion to realize, it is controllable that coupling mechanism force is adjustable, solve executing agency with inserting
Adhesion phenomenon between groove occurs, and can conveniently complete to perform action without using screw and instrument, improve locking device
Performance and the life-span.
The locking device coupling mechanism force that the present invention is provided is controllable, meets different printed boards under different operating environment to lock
The demand of clamp force.
Locking device contour structures of the present invention are simply compact, and space-consuming size is small, and reliable lock is high, locking
