Abstract
The utility model discloses a locking mechanism for a printed plate. The locking mechanism comprises a lever (2), a torsion spring (3), a pin (4), a channel plate (5), a cylindrical pin (6) and an roller (7), wherein, the both sides of the printed plate (1) are clipped in the mounting groove of the channel plate (5); one end of the torsion spring (3) is fixed on the printed plate (1), the other end of the torsion spring (3) is fixed at the tail end of the hook shaped slave arm (8) of the lever (2); the pin (4) is penetrated through the lever (2) and the torsion spring (3) and then is fixed on the printed plate (1), and the roller (7) is fixed at the tail end of the fork-shaped slave arm (9) of the lever (2) by using the cylindrical pin (6). Compared with the prior art, the locking mechanism for the printed plate has the advantages that the structure is simple, and the locking and pulling-out operation of the printed plate is convenient, effort-saving and quick, the locking is reliable, and the production efficiency is improved greatly.
Description
Technical field
The utility model relates to a kind of retaining mechanism of printed board.
Background technology
At present adopt pressing plate to compress or utilize the mounting panel of screw printed board usually to the locking of printed board; The plugs and sockets that directly connects printed board with screw is also arranged.But these versions make the plug of printed board, locking operation more loaded down with trivial details, very inconvenient, cause production efficiency low.
The utility model content
The purpose of this utility model is, a kind of retaining mechanism of simple, convenient, printed board efficiently is provided, thereby solves the problem that prior art exists, and enhances productivity.
The utility model is to constitute like this: the retaining mechanism of printed board.Comprise lever, torsion spring, bearing pin, frid, straight pin and roller, the both sides of printed board are stuck in the mounting groove of frid; One end of torsion spring is fixed in the printed board, and the other end is fixed on the hook-type slave arm end of lever; Bearing pin passes lever, torsion spring and is fixed in the printed board, and lever, torsion spring can rotate around bearing pin; Roller is fixed on the fork-shaped slave arm end of lever with straight pin, and roller can rotate around straight pin.
In the retaining mechanism of above-mentioned printed board, on lever and fork-shaped slave arm, be equipped with spacing block set.
The utility model adopt two have only gathering sill frid constraint printed board about, seesaw, symmetry is installed lever at drift angle place, the left and right sides of printed board, this lever has two slave arms, one is the hook-type slave arm, its end is a hook-shape structure, another is the fork-shaped slave arm, and its end is a fork configuration, and a roller is installed.When the printed board insertion put in place, the hook-type slave arm hooked in the corresponding aperture of frid under the effect of torsion spring, thus the locking printed board.When upwards mentioning lever, the rotation of two slave arms, at first the hook-type slave arm breaks away from frid, remove the locking of printed board and frid, and then the roller of fork-shaped slave arm end contacts with the end face of frid, when continuing upwards to mention lever, printed board begins to move up under the effect of lever, is extracted fully up to printed board.Compared with prior art, of the present utility model simple in structure, the locking of printed board, to transfer to easy to operately, laborsaving, quick, reliable lock has improved production efficiency greatly.

Embodiment
Embodiment of the present utility model: shown in accompanying drawing 1,2 or 3, comprise lever 2, torsion spring 3, bearing pin 4, frid 5, straight pin 6 and roller 7, the both sides of printed board 1 are stuck in the mounting groove of frid 5, printed board 1 can only be moved up and down, respectively there are two apertures at the angle on the both sides of printed board 1, an end that is used for fixing torsion spring 3, another is used to install bearing pin 4; Torsion spring 3 other ends are fixed on hook-type slave arm 8 ends of lever 2; Bearing pin 4 passes lever 2, torsion spring 3 and riveted and fixed (or fix with other modes such as bolts), and in printed board 1, lever 2, torsion spring 3 can rotate within the specific limits around bearing pin 4; The terminal perforate of fork-shaped slave arm 9 is used to install roller 7, and roller 7 usefulness straight pins 6 fixing (also can fix with other fixed form such as rivet) are at fork-shaped slave arm 9 ends of lever 2, and roller 7 can rotate around straight pin 6.Slewing area for restriction lever 2 respectively is provided with a spacing block set in the appropriate location of lever 2 and fork-shaped slave arm 9.
Operation principle: as accompanying drawing 1, after printed board 1 is inserted and is put in place, lever 2 rotates the hook end that makes hook-type slave arm 8 and snaps in the respective aperture of frid 5 under the effect of torsion spring 3, thereby printed board 1 can not be moved up and down, simultaneously the mounting groove of frid 5 retrained printed board 1 about, seesaw, so printed board 1 can be locked reliably.Because the effect of spacing block set, the limit slewing area of lever 2 is shown in accompanying drawing 5, accompanying drawing 6.As accompanying drawing 6, when printed board 1 was inserted downwards, the inclined-plane of the hook-type slave arm 8 of lever 2 at first contacted with frid 5, and hook-type slave arm 8 rotates under the effect of reaction force, put in place up to inserting as accompanying drawing 1.Under the state of accompanying drawing 1, upwards carry lever 2, lever 2 rotations, hook-type slave arm 8 breaks away from frid 5, and the roller 7 on the fork-shaped slave arm 9 contacts with the upper surface of frid 5, as accompanying drawing 4, the restriction cancellation that printed board 1 this moment moves upward.Continue upwards to carry lever 2, lever 2 drives printed board 1 when rotating and moves up to shown in the accompanying drawing 5.Lever 2 moves upward until extracting fully but continue to drive printed board 1 because the restriction of spacing block set stops operating afterwards.
Claims (2)
1. the retaining mechanism of a printed board comprises lever (2), torsion spring (3), bearing pin (4), frid (5), straight pin (6) and roller (7), and it is characterized in that: the both sides of printed board (1) are stuck in the mounting groove of frid (5); One end of torsion spring (3) is fixed in the printed board (1), and the other end is fixed on hook-type slave arm (8) end of lever (2); Bearing pin (4) passes lever (2), torsion spring (3) and is fixed in the printed board (1), and lever (2), torsion spring (3) can rotate around bearing pin (4); Roller (7) is fixed on fork-shaped slave arm (9) end of lever (2) with straight pin (6), and roller (7) can rotate around straight pin (6).
2. the retaining mechanism of printed board according to claim 1 is characterized in that: be provided with spacing block set at lever (2), fork-shaped slave arm on (9).
