Description
Technical field
This utility model relates to a kind of pcb board card and installs supplementary structure, particularly relates to a kind of pcb board card drawing-aid device。
Background technology
Existing multi-service access system cabinet, its pcb board card fixing structure needs to meet pcb board card and is prone to the requirement of plug, board inserts cabinet along guide rail from panel, when being inserted into bottom, with drawing-aid device, board and cabinet are fixed, the function of existing drawing-aid device is that auxiliary realizes the pcb board card location away from plug-in card one end, or enough utilizes lever principle power-assisted to extract board, makes the plug of pcb board card convenient。
In prior art, drawing-aid device is roughly divided into two kinds: a kind of be that fastening board function and helping pulls out that functional separation realizes a kind of be fastening board function and help and pull out function and realized by a structural member。All there is the weak point of some in above two drawing-aid device: two kinds of above-mentioned drawing-aid devices are in order to take into account fastening and the effect helping to pull out, result is all more complicated, needs arrange extra bolt or trip bolt structure, thus bring the impaired deformation of drawing-aid device and cause disabler even to affect the hidden danger of board plug。Most importantly, the labyrinth of this two classes drawing-aid device causes that drawing-aid device overall volume is difficult to compress the design influencing whether cabinet surrounding structure, when being particularly applied in the pursuit miniaturization board close cabinet of arrangement, increasing chassis design difficulty, the cost of drawing-aid device and difficulty of processing are also higher simultaneously。
In existing patent documentation, Chinese patent Authorization Notice No. CN203233622U, disclose the board drawing-aid device device of a kind of multi-service access system frame, including drawing-aid device, this drawing-aid device includes clamping part and the handle portion that handle portion and plug are bored a hole to board both ends, described clamping part arranges installing hole, described installing hole is equipped with pad successively and screw is installed, described pad, the board end plates two ends that drawing-aid device is installed on after screw is installed successively multi-service access system frame are installed。This solution simplifies drawing-aid device structure, but reduce the function that drawing-aid device fastens yet, the drawing-aid device of the program does not possess auto-lock function, has influence on the installation reliability of pcb board card。
Utility model content
This utility model is the many deficiencies in order to overcome pcb board card drawing-aid device of the prior art, it is provided that one is taken into account to help and pulled out and board lock function, and structure simplifies simultaneously, is conducive to the multimedia dispatching machine board location of cabinet overall construction design to help drawing machine structure。
For achieving the above object, this utility model is by the following technical solutions:
A kind of multimedia dispatching machine board location of the present utility model helps drawing machine structure, including the drawing-aid device being arranged on board panel, the locating aperture being arranged on case front panel, described locating aperture form fit board panel, drawing-aid device includes main part, be separately positioned on main part both sides pull arm and pulling piece, main part and board panel rotation connect, pulling piece is provided with the positioning convex of " L " shape towards the one side of board, the end of positioning convex is outwardly directed, and locating aperture sidewall is provided with the locating slot of corresponding described positioning convex end。
Drawing-aid device in this programme is rotatably connected on board panel, plays lock-bit and helps the effect pulled out。When board slips into cabinet along slide rail and inserts slot, the end of positioning convex snaps in and realizes self-locking in locating slot, and location board is away from one end of slot, it is prevented that board comes off or rocks。When board extracted by needs, outwards pulling arm makes drawing-aid device rotate, so that the pulling piece end top pressure surface plate of opposite side, positioning convex end also extracts the locking released board from locating slot simultaneously, continues to pull arm and utilizes lever principle to borrow power to be extracted by board。All realized by same action with self-locking it can thus be seen that this programme helps pull out, operate more convenient。And drawing-aid device structure simplifies, and can be produced by one-body molded injection molding, increasing drawing-aid device reliability and reduce the probability that movable device damages, simplify production technology and reduce cost, suitability height simplifies cabinet global design work。
As preferably, being provided with the fin of triangular structure inside the bending place of positioning convex " L " shape structure, locating aperture sidewall is provided with the groove coordinating fin, and described groove two ends time delay is to case front panel and locating slot。" L " shape structure of positioning convex is to realize the core texture of this programme board locking position, strengthens the structural strength of positioning convex by arranging fin, it is ensured that the service life of drawing-aid device。The matching relationship of the groove on fin and locating aperture sidewall adds positioning stablity degree。When board inserts, groove and fin play guide effect and ensure that the end of positioning convex accurately snaps in locating slot。
As preferably, when positioning convex end snaps in locating slot, pulling piece leaves gap between the one side and case front panel of board。When board is extracted, described gap ensure that when pulling arm, and the action of pulling piece contact case front panel is compared positioning convex and unlocked and have certain time delay, it is ensured that board is extracted smoothly。
As preferably, the corner of positioning convex " L " shape structure arranges rounding, and locating slot arranges rounding near case front panel one lateral edges。
As preferably, main part includes at least one place and is located close to the installing plate of board panel side, and described installing plate perpendicular plate card faceplate is also provided with axis hole。Board panel arranges rotation seat, installing plate and rotation seat be rotationally connected by bolt。
As preferably, described installing plate extends to pulling piece, and installing plate is provided with near the side of board panel and dodges breach, described in dodge breach between positioning convex and axis hole。Described dodge breach be pulling piece inwardly rotate help pull out time, it is prevented that the structure of board face plate edge causes interference, and restriction drawing-aid device rotates impact and helps and pulls out function。
As preferably, main part, pulling piece, pull arm and positioning convex is homogeneity integrative-structure。
As preferably, main part, pulling piece, pull arm, positioning convex, installing plate are homogeneity integrative-structure。
Therefore, this utility model has the advantages that (1) is taken into account board locking and helps and pull out function；(2) structure simplifies, and the suitability is strong, simplifies cabinet global design work；(3) reliability is high, long service life, it is easy to production cost is low。
