Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further described.
See shown in Fig. 1 ~ 3, a kind of ceiling structure of concealed installation projecting apparatus, mainly comprises supporting plate 1, motor 2, limit switch, gauge tap K1.The decorative panel 3 of furred ceiling is opened a rectangular breach; Corresponding with breach, be provided with one block of supporting plate 1, supporting plate 1 is for placing projecting apparatus 4, and the right of supporting plate 1 is connected with the decorative panel 3 of furred ceiling by hinge 5; Supporting plate 1 is also provided with anti-skidding baffle plate 6, prevents projecting apparatus 4 landing.Described motor 2 is arranged on top board 7 top of room (when namely not the fitting up); Between motor 2 and supporting plate 1, be provided with steel cable 8, one end of wire rope 8 is fixed on supporting plate 1, and the other end is fixed on the shaft of motor 2; The centre of wire rope 8 is provided with circular limiting plate 9.Described limit switch, comprises upper limit switch and limit switch; In order to improve security performance when supporting plate 1 is received above or puts down, the upper limit switch described in present embodiment and limit switch are respectively provided with 2.Above the suspended ceiling decorative plate 3 on the breach left side, be provided with limit switch mount pad 10, above mount pad 10, install 2 limit switch K2, K3,2 upper limit K switch 4, K5 are installed in the below of mount pad 10.
Described gauge tap K1 is employing three commutator, for receiving the control and the disconnection of projecting apparatus 4 power supply or the control of connection going up or put down to supporting plate 1.
Described limit switch K2, K3, upper limit K switch 4, K5, adopt normally closed push button switch, namely when the button of switch is not touched, is in closed communicating state.
As shown in Figure 3, gauge tap K1 is connected as follows with the circuit of limit switch and motor 2:
One end P1 of 220V power supply is connected with the pin K1-a of gauge tap K1, and pin K1-a1 and the pin K1-a2 of gauge tap K1 are connected rotating forward pin R and the reversion pin G of motor respectively.The other end P2 of 220V power supply is connected with the common pin Y of motor by limit switch K2, K3 and upper limit K switch 4, K5; Limit switch K2, K3 and upper limit K switch 4, K5 are the mode places in circuit of connecting.The pin K1-b of gauge tap K1 is connected between limit switch K3 and upper limit K switch 4, and the pin K1-b2 of gauge tap K1 is connected to the P2 end of power supply, and the pin K1-b1 of gauge tap K1 is connected on the common pin Y of motor.
Further, the pin K1-c of gauge tap K1 connects the P1 end of power supply, and pin K1-c1 is connected with the power supply of projecting apparatus 4, and the other end of projecting apparatus power supply is held with the P2 of 220V power supply and is connected.
The course of work of circuit is as follows:
When gauge tap K1 is placed in down state, namely the pin K1-a of gauge tap K1 is connected with pin K1-a1, pin K1-b is connected with pin K1-b1, pin K1-c is connected with pin K1-c1, now, the rotating forward pin R of motor 2 to be held with the P1 of 220V power supply by the pin K1-a1 of gauge tap K1 and pin K1-a and is communicated with; The other end P2 of 220V power supply is connected on the common pin Y of motor by the pin K1-b of limit switch K2, K3 and gauge tap K1 and pin K1-b1, and electrical power produces and rotates forward, and wire rope 8 constantly unclamps, and supporting plate 1 is slowly put down; When limiting plate 9 meets limit switch K2, K3, one of them disconnection of K2 and K3 or two switch, motor stalls.
When gauge tap K1 is placed in state in receipts, namely the pin K1-a of gauge tap K1 is connected with pin K1-a2, pin K1-b is connected with pin K1-b2, pin K1-c is connected with pin K1-c2, now, the reversion pin G of motor 2 to be held with the P1 of 220V power supply by the pin K1-a2 of gauge tap K1 and pin K1-a and is communicated with, the other end P2 of 220V power supply is connected on the common pin Y of motor 2 by the pin K1-b2 of gauge tap K1 and pin K1-b and upper limit K switch 4, K5, electrical power produces reversion, wire rope 8 is constantly strained, and supporting plate 1 is slowly received; When supporting plate 1 encounters upper limit K switch 4, K5, one of them disconnection of K4 and K5 or two switch, motor stalls.
Circuit working process recited above, if in upper limit K switch 4, K5, has a switch to there occurs short trouble, when another switch is touched, and still can disconnecting circuit; The operating principle of limit switch K2, K3 is the same.So, motor will be caused out of control because of the short circuit of a switch, improve security performance.
Above-mentioned circuit working process, when gauge tap K1 is placed in down state, one end P1 of power supply has been communicated with the power supply of projecting apparatus by pin K1-c, K1-C1; When gauge tap is placed in state in receipts, be disconnected the power supply of projecting apparatus.
Further, described motor, adopts 220V low profile gear motor, is band band-type brake, supports the motor of rotating function.
Above-described is only a kind of embodiment of the utility model, and to those skilled in the art, under the prerequisite not departing from the utility model principle, some variations in detail made, all should be considered as belonging to protection domain of the present utility model.
