Abstract
The utility model relates to a printed circuit board (PCB) self-adapting positioning and fixing mechanism, which belongs to the technical field of medical appliances. The PCB self-adapting positioning and fixing mechanism comprises a base plate rack (1), a card slot (2), an insulating pad (3), positioning pins (4), a connecting rod A (5), a connecting rod B (6), a return spring A (7), a return spring B (8), a pressing buckle (9), a switching board (10), a sliding block (11) and a PCB board (12), and is characterized in that: the insulating pad (3) is closely connected with the base plate rack (1); the card slot (2) is connected with the two connecting rods to form a connecting rod structure through the positing pins (4); the vertical linear motion of the sliding block (11) on the base plate rack (1) is changed into card slot (2) horizontal movement; the two connecting rods are connected with the base plate rack (1) through the return spring (7) to realize chucking or reset of the PCB board by the card slot (2); and the pressing buckle (9) tightly presses the PCB board from the return spring B (8), and realizes external switching through the switching board (10). The PCB self-adapting positioning and fixing mechanism has the advantages of wide application range, simple structure, no need of unlocking, and labor saving during plugging and unplugging.
Description
Technical field
The utility model belongs to technical field of medical instruments.
Background technology
At present, the development that China's electron trade is being advanced by leaps and bounds, the automaticity of product is increasingly high; Pcb board use also more and more widely; But in patent application, also have a variety of in its fixed form: a kind of and for example patent ZL 200420091039 (circuit board fixation structure) utilizes engaging support mechanism to interfere each other like ZL96232122.2 (printed circuit board locking device) rotational lock formula, and ZL99220997.8 (circuit board is used fixed support) utilizes fixed support screw thread compression type etc.; Their shortcoming is: using has limitation; Electrical control utilization big is less, and fixed size is single, and pcb board is had specific requirement etc.
Summary of the invention
The purpose of the utility model is: overcomes the inconvenience that structure is in the past used on large-scale control cubicle, considering the characteristics of large-scale electric cabinet, solving the insulation of fixture, shockproof, shielding anti-interference problem emphatically, and installation and maintenance and a kind of novel mechanism of designing.
The utility model solves the technical scheme that its technical problem adopted: its structure is made up of floor board framing, draw-in groove, insulation cushion, alignment pin, connecting rod A, connecting rod B, back-moving spring A, back-moving spring B, clinching, keyset, slide block, pcb board; Its technical characterictic is: insulation cushion is close to floor board framing; Draw-in groove is connected with connecting rod A, connecting rod B; Form bar linkage structure through alignment pin; The vertical line of slide block on the track of floor board framing moves through the horizontal movement that connecting rod A, connecting rod B are converted into draw-in groove, and connecting rod A, connecting rod B are connected with floor board framing through back-moving spring in position, and the realization draw-in groove tightens pcb board or resets; Clinching again through back-moving spring B from compressing pcb board, pcb board is through externally switching of keyset (10).
The beneficial effect of the utility model is: applied range, and easy to use to large-scale control cubicle; Simple in structure, reliable lock need not release, plugs laborsaving.
