Abstract
The utility model relates to a PCB pinch plate locking mechanism which is used for rapidly mounting and dismounting a PCB motherboard and a pinch plate. The PCB pinch plate locking mechanism comprises a captive screw, a return spring and a spacing nut. The captive screw passes through the installing hole of the PCB pinch plate, the return spring and a gasket are arranged between the head portion of the captive screw and the PCB pinch plate, the spacing nut is arranged between the tail portion of the captive screw and the PCB pinch plate. According to the PCB pinch plate locking mechanism, mounting and dismounting are simple and fast.
Description
Technical field
The utility model relates to the PCB buckle retaining mechanism of a kind of Fast Installation for pcb board part, buckle and dismounting.
Background technology
Installation process between common PCB motherboard, buckle, first spacing nut is arranged on stationary plane, then the installing hole of PCB motherboard, buckle is aimed at corresponding spacing nut, then the screw that installs bullet, plain cushion is arranged on spacing nut through PCB motherboard, buckle.In its installation process; need a hand steered firmly buckle, another hand mounting screw, often there will be bullet, plain cushion or screw misalignment spacing nut or falls into the situations such as cabinet inside; under some specific condition, need two people to coordinate PCB motherboard, buckle could be installed, affect operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of PCB buckle retaining mechanism that mounts and dismounts simple and fast is provided.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of PCB buckle retaining mechanism, comprise captive screw, back-moving spring and spacing nut, described captive screw is through the installing hole of PCB buckle, between the head of captive screw and PCB buckle, back-moving spring and packing ring are set, between the afterbody of captive screw and PCB buckle, spacing nut are set.
And described packing ring is plain cushion.
And the side endoporus that described spacing nut contacts with PCB buckle has the screw thread adapting with captive screw, spacing nut has away from a side endoporus of PCB buckle the resigning hole adapting with captive screw.
The utility model has the advantage of: 1. PCB buckle retaining mechanism, pcb board are with kit form integral disassembly, assembly, and efficiency of assembling is high; 2.PCB buckle retaining mechanism screw can be upspring after exiting screw thread, automatically resets; 3.PCB buckle locking machine integrate automatically reset, pine is de-and automatically determine distance between plates from; 4.PCB buckle retaining mechanism screw, plain cushion, spacing nut has anti-drop function, avoids falling into cabinet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view Amplified image at A place in Fig. 1.
Fig. 3 is assembling view of the present utility model.
Wherein, 1, captive screw, 2, back-moving spring, 3, plain cushion, 4, PCB buckle, 5, spacing nut.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of PCB buckle retaining mechanism, comprise captive screw 1, back-moving spring 2 and spacing nut 5, described captive screw 1 is through the installing hole of PCB buckle 4, between the head of captive screw 1 and PCB buckle 4, back-moving spring 2 and packing ring are set, between the afterbody of captive screw 1 and PCB buckle 4, spacing nut 5 are set.
Further, above-mentioned packing ring is plain cushion 3.
Further, the side endoporus that above-mentioned spacing nut 5 contacts with PCB buckle 4 has the screw thread adapting with captive screw 1, and spacing nut 5 has away from a side endoporus of PCB buckle 4 resigning hole adapting with captive screw 1.
During the utility model work, press captive screw 1 compression reseting spring 2, through plain cushion 3, captive screw 1, back-moving spring 2, plain cushion 3, installation are assembled into an assembly with pcb board part, PCB buckle 4, spacing nut 5, back-moving spring 2, plain cushion 3 when plate is installed have been avoided, captive screw 1, spacing nut 5 disperses separately, the situation such as be difficult for to aim at installing hole or fall in cabinet.This programme only needs the hand steered good PCB buckle 4 of an of operator, and captive screw 1 is aimed to corresponding installing hole, and another hand is pressed captive screw 1 and screwed in installing hole, just the light first-class captive screw 1 of energy; In dismounting during plate, captive screw 1 is exited the reset of can automatically upspringing after retaining thread is installed.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement or distortion, these improvement or distortion also should be considered as protection range of the present utility model.
