Detailed Description

The following description is presented to enable one of ordinary skill in the art to make and use the utility model. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.

The utility model provides a prevent disassembling little household electrical appliances PCB controller as shown in figure 1-figure 6, including the bottom plate 1 of horizontal setting, bottom plate 1 lateral wall activity has cup jointed shell 2, bottom plate 1 up end fixed mounting has PCB board 3, PCB board 3 up end fixed mounting has a plurality of buttons 4, button 4 lateral wall activity has cup jointed the key cap 5 of a plurality of activity run through shell 2, recess 6 has transversely been seted up to bottom plate 1 lateral wall, recess 6 inner wall has fixture block 8 with recess 6 inside wall sliding fit through spring 7 fixed mounting, fixture block 8 activity embedding shell 1 inside wall, fixture block 8 is connected with joint cancellation mechanism, joint cancellation mechanism includes the cancellation groove 9 of vertical seting up at bottom plate 1 lower extreme face, be provided with the wire 10 of activity run through bottom plate 1 and extending to in the recess 6 in the cancellation groove 9, wire 10 and 8 fixed connection, spring 7 activity cup joints at wire 10 lateral wall in wire 10, pull wire 10 in cancellation groove 9 can make 8 overcome spring 7's effort retract into recess 6, cancel the joint, carry out the joint to shell 2 through setting up fixture block 8 and fix when the fixture block, make the device can not fall on the ground at the same time at the control wire 8, make the fixture block is convenient and fast to disassemble the fixture block.

Specifically, the sealing block 11 is installed to the inside wall screw thread of cancellation groove 9 lower part, and rotatory groove 12 has been seted up to sealing block 11 lower terminal surface, and sealing block 12 is used for covering cancellation groove 9, avoids steel wire 10 to expose, sets up rotatory groove 12 simultaneously for the taking off of sealing block 11 is simple and convenient more.
