Description
Technical field
The tightening technology field that the present invention relates to printed boards in cabinet slot, and in particular to a kind of nonstandard printed board is in machine
Quick locking and release in case slot just can reach fastening effect without using the operation of screw and other tools.
Background technique
Nonstandard printed board after being inserted into cabinet slot, fasten it is locking, with prevent during transportation, due to vibration
The influence of the external force such as dynamic, impact, printed board is swung at random taps chassis shell body, causes printed board to deform and rupture, or make to print
Electric connector between plate and motherboard loosens, and causes electric connector contact bad or breaking.
Fastening of the nonstandard printed board in cabinet slot, it is real that existing fastening means mostly uses greatly wedge locking device
It is existing, screw fastening means is used individually.
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, squeezes mobilizable upper wedge type block, keeps wedge type block raised, when protrusion is more than that wedge is locked
The substantially planar certain size of device fits closely with cabinet slot inside, continues rotary screw, upper wedge type block is in cabinet slot
Biggish extruding force is generated, so that the printed board to link together be made to fasten；When unlock, screw is reversely rotated, by lower wedge type block
It exits, after upper wedge type block does not have extruding force, is just unclamped naturally with slot.Such locking device advantage is that structure is simple, at low cost,
The disadvantage is that such locking device need to be operated by tool (bottle opener), the extruding force of generation leans on the feel and experience of operator,
Often occur because extruding is excessive, upper wedge type block and the adhesion of slot inner wall cause printed board that can not extract, at this moment need with other stocks
Tool protrudes into and stirs wedge type block in slot, is allowed to disengage adhesion state with slot inner wall；What is more, screw slide fastener or disconnected
It splits, causes printed board that can not extract, the method for destroying constitutional detail can only be used, can just printed board be made to extract.In certain special feelings
Under condition, scene does not have tool (bottle opener), when needing to extract printed board, then helpless, after calling in tool, then wastes big
The time and efforts of amount.
Using the printed board in screw fastening slot, usually printed board bottom is connect with motherboard by electric connector, is printed
It is then connect with screw with slot outer end face at the top of making sheet.Such printed board fastening means, advantage are structure letter, at low cost, disadvantage
It is that such locking device need to be operated by tool (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, position seems weak among printed board, in transport because vibrating and impacting possibility
It can damaged fracture.
Summary of the invention
For problem of the prior art and urgent technical need, the present invention provides a kind of printed boards in cabinet slot
Locking device, it is intended that solving quick locking of the nonstandard printed board in cabinet slot and loosening, coupling mechanism force is controllable, no
Achievable printed board is locked and loosened movement using the operation of screw and tool, shortens the assembly, maintenance and detection of printed board
Time.
To achieve the above object, according to one aspect of the present invention, the invention discloses a kind of printed boards in cabinet slot
Interior locking device, including be symmetrical set and identical two locking units of structure；Locking unit includes locking support, leads
To pin, positioning lock shaft, tense item, sliding-tongue shaft, sliding-tongue and elastic force compression bar；
The locking support is L shape elongate body, and the top of L shape long side has a trunnion with U-lag；
The tension item is strip, and positioned at the L shape long side 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 for tensing item, can only be moved up and down for limiting tension item；
The positioning lock shaft is a straight pin with the level, concordant with locking support L shape long side end face riveting, from end face
Back is stretched out；
The sliding-tongue shaft is a straight pin with the level, and the sliding-tongue shaft passes through the countersunk head through-hole for tensing item, and
It is inserted in sliding-tongue and rivets；
The sliding-tongue is the elongate body of a both ends semicircle, and there are 1 circular through hole and 1 long round tube hole, the circle in front
Through-hole is riveted with the sliding-tongue shaft tensed on item is mounted on, the long round tube hole and positioning lock shaft riveting；
The elastic force compression bar is single pole spring wire, and one end is connect with the upper end through-hole for tensing item, and intermediate point is placed in lock
In the trunnion with U-lag of tight support, the other end is as operating side.
Further, the guide pin is a straight pin with the level, flat with the riveting of the shape long side end face locking support L
Together, and from end face back it stretches out.
Further, the free end of the L shape short side of the locking support bends and slots, and notch is another as elastic force compression bar
The supporting point of one intermediate point.
Further, the operating side of the elastic force compression bar is processed as handle shape.
Technical effect of the invention:
Printed board locking device provided by the invention is compared with domestic printed board locking device more common at present, locking
Mode has significant difference.Printed board locking device provided by the invention uses link mechanism, lever form, material shell-shaped deformation three
Kind different executive modes and principle realizes that locking and unlocking act, and it is controllable that coupling mechanism force is adjustable, solve executing agency and insert
Adhesion phenomenon between slot occurs, and can conveniently complete to execute movement without using screw and tool, improve locking device
Service performance and the service life.
Locking device coupling mechanism force provided by the invention be it is controllable, meet different printed boards under different operating environment to lock
The demand of clamp force.
Locking device contour structures of the present invention are simple and compact, and occupied space size is small, and reliable lock is high, locking
Power is controllable, does not use screw and tool, easy to operate.Suitable for the locking and unlocking of nonstandard printed board, ease for use and can operate
Property it is good, convenient for complete fast quick-detach, installation, debugging and the troubleshooting of printed board, there is preferable application value and promotion prospect.
