Detailed Description
As shown in fig. 1, a protection device for a switch of a graphene electric heating table comprises a first groove 2 formed on a table plate 1, wherein the front end of the first groove 2 penetrates through the front side surface of the table plate 1, and is characterized in that a movable block 22 is slidably arranged in the first groove 2, a switch 23 is fixedly embedded at the upper end of the movable block 22, the switch 23 is a ship-shaped switch, the rear end of the movable block 22 is connected with the rear groove wall of the first groove 2 through a first spring 13, fixed blocks 14 are symmetrically fixed at the rear ends of the left side and the right side of the movable block 22, a through hole 15 communicated with the first groove 2 is formed in the table plate 1 at the front side of the left fixed block 14, a hole stopper 16 is fixed in the through hole 15, a square rod 26 penetrates through the hole stopper 16 and is in sliding fit with a square hole on the hole stopper 16, a first stopper ring 17 is fixed on the square rod 26 at the left side of the hole stopper 16, a second stopper ring 20 is fixed on the square rod 26 at the right side of the hole stopper 16, a second, first fender ring 17 keeps off 16 contacts with the hole, and the terminal surface of the square bar 26 one end in the first recess 2 is the inclined plane of front end slope to the left side, and the square bar 26 rear end contacts with the fixed block 14 front end on right side, one of square bar 26 keeping away from movable block 22 is served and is fixed with stay cord 18, is fixed with pull ring 19 on the stay cord 18.
Be provided with dust guard 4 in the first recess 2 of movable block 22 front side, the left cell wall that 4 left ends front sides of dust guard and first recess 2 passes through spring hinge 5 to be connected, is fixed with baffle 6 on the right cell wall of first recess 2, and baffle 6 is located 4 backs of dust guard and rather than the contact, and the movement track of the fixed block 14 on right side passes through baffle 6, all be provided with the minimum clearance that allows 4 rotations of dust guard about dust guard 4 between both ends and the cell wall about first recess 2.
The second recess 7 has been seted up on the right cell wall of first recess 2, second spout 8 has all been seted up along the length direction of second recess 7 on the upper and lower cell wall of second recess 7, it is provided with second slider 10 all to slide in the second spout 8, it connects between two second sliders 10 to lead rope sheave 11 to rotate, second slider 10 passes through elastic webbing 12 with the rear side cell wall of second spout 8 and is connected, switch 23's control line 9 part is fixed in movable block 22, the rear end face of movable block 22 is run through to control line 9 one end, the outside control line 9 one end of movable block 22 is walked around and is passed behind rope sheave 11 and pass behind the line hole 25 in the second recess 7 front side table 1 behind the graphite alkene electric connection on power and the electric heat membrane table 1, the drill way department threaded connection of line 25 has the line to detain 24, control line 9 runs through line detain 24 and rather than fixed connection.
A longitudinal first sliding groove 3 is formed in the lower groove wall of the first groove 2, a first sliding block is arranged in the first sliding groove 3 in a sliding mode, the first sliding block is fixedly connected with the lower end of the movable block 22, and the cross sections of the first sliding groove 3 and the first sliding block are both trapezoidal.
When the utility model is used, the square bar 26 is pulled to move to the left by the pull ring 19 and the pull rope 18, the second retaining ring 20 extrudes the second spring 21, when the right end of the square bar 26 loses the blocking effect on the left fixed block 14, the first spring 13 enables the movable block 22 to move to the front side, the movable block 22 is contacted with the dustproof plate 4 and then drives the dustproof plate 4 to rotate around the shaft of the spring hinge 5 until the fixed block 14 on the right side is contacted with the retaining plate 6, the switch 23 on the movable block 22 is positioned outside the first groove 2 at the moment, the graphene electrothermal film on the table plate 1 can be opened by the switch 23 and then the movable block 22 is pushed into the first groove 2, when the left fixed block 14 is contacted with the inclined plane of the square bar 26, the square bar 26 moves to the left under the guiding effect of the inclined plane, the second spring 21 is compressed, when the left fixed block 14 is positioned behind the square bar 26, the second spring 21 enables the square bar 26 to restore and further block the left fixed block 14, the movable block 22 is now confined within the first recess 2.
When the movable block 22 moves to the outside direction of the first groove 2, the control line 9 in the first groove 2 and the second groove 7 enables the rope guide wheel 11 to move to the front side direction in the second groove 7, the control line 9 pulls the elastic belt 12 through the rope guide wheel 11, the elastic belt 12 stores force, when the movable block 22 moves to the inside direction of the first groove 2, under the elastic force action of the elastic belt 12, the elastic belt 12 enables the rope guide wheel 11 to move to the rear side in the second groove 7, the control line 9 is always in a tightening state at the moment, and therefore knotting or winding of the control line 9 in the first groove 2 and the second groove 7 can be effectively prevented, and the control line 9 is prevented from being worn.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
