The utility model provides a knob seat.

In the embodiment of the present invention, as shown in fig. 1 and fig. 2, the knob base includes a base 10 and a clamping member 20, the base 10 has a mounting cavity for accommodating a PCB 30; the clamping piece 20 is arranged in the mounting cavity and is connected with the PCB 30 in a clamping mode. The PCB 30 passes through the clamping piece 20, and the clamping piece 20 is meshed with the PCB 30 to play a role in fixing the PCB 30 and fix the PCB 30 on the base 10.

In an embodiment, the base 10 includes a bottom plate 101, the periphery of the bottom plate 101 extends upwards to form a side wall 102, and a mounting cavity is formed between the side wall 102 and the bottom plate 101 for accommodating the PCB 30 with a size matched with the side wall, so that the PCB 30 can be fixed on the bottom plate 101, as a preferred embodiment, the mounting cavity is configured to conform to the shape of the accommodated PCB 30 and just can accommodate the PCB 30.

In an embodiment, as shown in fig. 4, the clamping member 20 includes a connecting rod 201 and a clamping rod 202, one end of the connecting rod 201 is vertically fixed on the base 10, the other end of the connecting rod 201 is connected with the upper end of the clamping rod 202, and the lower end of the clamping rod 202 is directed downward toward the base 10, so that the clamping function can be realized. As an optional implementation manner, the connecting rod 201 is made of a metal material or a plastic or other stable material which is not easily deformed, so that the connecting rod is not deformed when being subjected to an external force, and the service life of the connecting rod can be prolonged.

Further, the angle between clamping rod 202 and connecting rod 201 is less than 90 degrees. When the surface of the clamping rod 202 is applied with a vertically downward force of the PCB 30, since the angle between the clamping rod 202 and the connecting rod 201 is smaller than 90 degrees, the clamping rod 202 generates a component force perpendicular to the direction of the connecting rod 201, so that the clamping rod 202 can move towards the direction of the connecting rod 201, and the PCB 30 can be connected and fixed with the base 10 without being blocked by the clamping rod 202.

Further, the snap rod 202 is an elastic member. When the lower surface of the PCB 30 contacts with the clamping rod 202, the clamping rod 202 receives the extrusion force of the PCB 30 to the clamping rod 202 along the horizontal direction, and at this time, the clamping rod 202 elastically deforms toward the connecting rod 201, and when the upper surface of the PCB 30 passes through the clamping rod 202, the clamping rod 202 does not receive the extrusion force of the PCB 30 to the clamping rod, and at this time, the clamping rod 202 returns to the original position under the action of the elastic force of itself to abut against the upper surface of the PCB 30, so as to fix the PCB 30 on the bottom plate 101. Clamping pole 202 sets up to the elastic component can play better joint effect, and when needing to take off PCB board 30, only need press clamping pole 202 toward connecting rod 201 direction, just can easily take out PCB board 30, need not frequently to dismantle or install the screw, makes PCB board 30's dismantlement and installation more convenient simple.
