Abstract
The utility model relates to a pull switch, which belongs to an improved structure of a pull switch of an electric appliance. The pull switch comprises a self-locking type round button switch which is fixedly arranged at the lower part of the interior of a cylindrical switch fixing rack. The two ends of a connecting pin are fixedly connected to the two opposite side walls of the switch fixing rack respectively, a torsional spring is mounted on the connecting pin and a connecting rod with a bulge at the lower part thereof is hinged at the lower part of the connecting pin, one end of the torsional spring is bent and clamped in the through hole of the connecting rod while the other end of torsional spring is blocked on the side wall of the switch fixing rack, the connecting rod extends out of a position limiting groove formed on the side wall, the extension end of the connecting rod is connected with a pull wire, and the bulge on the connecting rod is matched with the button of the self-locking type round switch. The pull switch provided by the utility model has simplified structure, prolonged service life and improved reliability, and is convenient for maintenance.
Description
Technical field
The utility model belongs to the improvement of electric stayguy switch fabric, particularly a kind of pulling switch.
Background technology
Existing pulling switch is equipped with the elastic pawl brace on the terminals A, the ratchet pawl axle is installed with the three-jaw brace, and the bending brace is housed on the terminals B, and bending brace one end is enclosed within on the ratchet shaft and with the three-jaw brace and fits together.Connecting rod is installed in that the elastic force by torsion spring fits together connecting rod side and ratchet shaft end face on the ratchet shaft.Connecting rod and ratchet shaft composition surface are one-way clutch formula structure, and when spurring connecting rod downwards, connecting rod drives ratchet shaft and rotates.After unclamping connecting rod, connecting rod side seam separates with ratchet shaft, elastic pawl brace restriction ratchet shaft backward rotation, and connecting rod resets under the torsion of torsion spring.This moment, the elastic pawl brace was connected with the three-jaw brace, and terminals A, B connect.The pull bar (motion principle is the same) of leaving behind once more, the elastic pawl brace separates with the three-jaw brace, and terminals A, B disconnect.
The connecting rod of existing pulling switch and ratchet shaft be unit to the disengaging type structure, the seam position inefficacy easy to wear of faying face causes malfunctioning switch.The connection of terminals A, B is that contact-making surface is interconnected between three-jaw brace and the bending brace by the elastic pawl brace.When switch inside enters dust or brace surface oxidation, can cause loose contact between each brace, malfunctioning switch.The parts of existing pulling switch are more, fragile in addition, not easy-maintaining.
Summary of the invention
The purpose of this utility model is to provide a kind of pulling switch, not only simplifies the structure of pulling switch, and has improved the useful life and the reliability of pulling switch, is convenient to maintenance simultaneously.
The purpose of this utility model is achieved in that a kind of pulling switch, comprise self-locking type round button switch, bottom in square tube shape switch fixed mount is installing self-locking type round button switch, the two ends of connecting pin are fixed in respectively on the corresponding two side of switch fixed mount, the lobed connecting rod of torsion spring and articulated bottom is installed on connecting pin, one end bending termination of torsion spring is stuck in the through hole of connecting rod, other end retaining is on the sidewall of switch fixed mount, connecting rod stretches out in the stopper slot of sidewall setting, its end of stretching out is connecting backguy, and the projection on the connecting rod matches with the button of self-locking type round button switch.
The utility model is that a self-locking type round button switch is fixed on the switch fixed mount, the torsion spring that connecting rod is housed on the switch fixed mount and connecting rod is resetted, and connecting rod and torsion spring are installed on the switch fixed mount by connecting pin.Spur connecting rod downwards, the projection that the connecting rod bottom is provided with is pressed the button on the self-locking type round button switch, unclamps connecting rod, and connecting rod resets under the twisting force of torsion spring, finishes the break-make of terminals A, B.The utility model is not only simplified the structure of pulling switch, and has improved the useful life and the reliability of pulling switch, is convenient to maintenance simultaneously.

The utility model is described in further detail below in conjunction with accompanying drawing,
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 looks the broken section structural representation for the left side of Fig. 1;
Structural representation when Fig. 3 works for the utility model switch.
Embodiment
A kind of pulling switch, as Fig. 1, Fig. 2, shown in Figure 3, comprise self-locking type round button switch 2, bottom in square tube shape switch fixed mount 1 is installing has terminals A, the self-locking type round button switch 2 of B, the two ends of connecting pin 6 are fixed in respectively on the switch fixed mount 1 corresponding two side, the lobed connecting rod 4 in torsion spring 5 and articulated bottom is installed on connecting pin 6, one end bending termination of torsion spring 5 is stuck in the through hole of connecting rod 4, other end retaining is on the sidewall of switch fixed mount 1, connecting rod 4 stretches out in the stopper slot 9 of sidewall setting, its end of stretching out is connecting backguy 3, and the projection on the connecting rod 4 matches with the button 8 of self-locking type round button switch 2.On the button 8 of self-locking type switch switch 2 metal cap 7 is installed.7 pairs of buttons 8 of metal cap play protective effect, prevent button 8 excessive wears, improve the useful life of switch.The inserting column 10 of self-locking type round button switch 2 holders one end setting matches with the bayonet socket on switch fixed mount 1 sidewall, the support arm of its other end setting is connected by screw on the flanging of the outside bending of fixed mount 1 corresponding sidewall, matches with the flanging of the inside bending of fixed mount 1 lower sidewall in the lower end of self-locking type switch 2 holders.Make the utility model fixedly connected reliable, be convenient to dismounting.The effect of stopper slot 9 is distances that control link 4 swings up and down, and prevents connecting rod 4 double swerves.
