Abstract

The utility model relates to an emergency stop button for switches, which comprises an upper cover 13 and a base 4. The utility model is characterized in that a core shaft which is used for connecting the upper cover and the base is sheathed with a torsional spring, the acting force of which makes the expanded angle of the upper cover and the base limited in a reasonable position. A whole structure is made to be more reasonable. The emergency stop button has the advantages of long service life, flexible operation, high commercialization degree, etc. The emergency stop button for switches is suitable for being used as an emergency stop operating mechanism for controlling switches.

Description

The anxious button that stops of switch

The utility model relates to the anxious button that stops of a kind of switch, is used for control switch.

The control switch of using always in the factory, as electromagnetic switch, there are two buttons its body top, is respectively " start button " and " stop button ", to control mechanical entry into service or to shut down.But this kind switch often makes the operator can not make quick reflection when state of necessity takes place machinery, presses shutdown switch exactly, so that make machinery stall at once.In order to change the defective that this traditional control switch exists, someone once invented a kind of urgent clinching safety switch, urgency of device is stopped clinching on the control switch body, when machinery generation emergency episode, operating personnel only pat the anxious clinching that stops, suddenly stop clinching " stopping " button down, machinery is shut down control switch.The urgent clinching of the switch of this invention as shown in Figure 1.Be made of with following the seat of honour, following seat is the tetragonal body of hollow, and latching device is set on the seat of honour, and seat connects by bearing pin up and down, in the open-shaped attitude in the nature seat of honour.Open excessive angle for preventing the seat of honour, operating personnel pat when influencing the state of emergency, this invention is provided with a position-limiting spring leaf in upper and lower seat junction, with the open angle in the restriction seat of honour, but this reed is a common plastics reed A who exposes, and the user reflects that generally commercialized degree is poor, and plastic sheet is easily aging simultaneously, the endurance degree is poor, and useful life is short.There are shortcomings such as operating handle difference in the clinching mechanism of the urgent clinching of this switch in addition.

The utility model purpose is to provide a kind of switch the anxious button that stops, and the position-limit mechanism of its seat of honour opening angle more becomes rationally, and long service life makes clinching mechanism have better result of use simultaneously.

The technical solution of the utility model is: the anxious button that stops of a kind of switch, comprise loam cake and base, on covered locking closure, jam plate and U-shaped and detained outward, button in the U-shaped is arranged on the base, there is mandrel the end of loam cake, there is axle bed the end of base, and axis hole is arranged on the axle bed, and loam cake and base connect by mandrel and axis hole, it is characterized in that being with on the mandrel torsion spring, on the draw-in groove that one arm of torsion spring is fixed, another arm counter-rotating of torsion spring is fixed on the arm seat of base, makes loam cake and base open reasonable angle under the effect of torsion spring.

When emergency took place, external force was patted locking closure, and loam cake and base close up, the outer retaining ring of U-shaped advances in the U-shaped to buckle, and smashs in the jam plate tongue insertion U-shaped and pin interior button, and loam cake and base can't be separated, loam cake is forced the stop button of depress switch simultaneously, and machinery is shut down.

Because the utility model adopts torsion spring to substitute the common plastics reed in the prior art and structurally does further perfect, it is easily aging both to have overcome plastic sheet, shortcomings such as useful life is short, increase loam cake position-limit mechanism useful life, and the raising commercialized degree, be suitable for the urgency of making control switch and stop operating mechanism.

Below in conjunction with embodiment and accompanying drawing thereof technology contents of the present utility model is described further.

Fig. 1 stops the buckle structure schematic diagram for known switches is anxious.

Fig. 2 stops detaining a kind of embodiment global shape schematic diagram for the utility model switch is anxious.

The structural representation that Fig. 3 is Fig. 2 latching device when following combines.

Fig. 4 stops detaining each main member structural representation for Fig. 2 switch is anxious.

By Fig. 2, Fig. 3 as can be known, the anxious button that stops of this switch comprises loam cake 13 and base 4, on covered the outer button 14 of locking closure 21, jam plate 17 and U-shaped, button 5 in the U-shaped is arranged on the base, there is mandrel 10 the loam cake end, and base end has axle bed 1, and axis hole 3 is arranged on the axle bed, mandrel 10 and axis hole 3 assemblings are together, it is characterized in that being with on the mandrel 10 torsion spring 8, torsion spring one arm is fixed on the draw-in groove 11, and another arm counter-rotating of torsion spring is fixed on the arm seat 2 of base.Fig. 2 stops buckle in the nature schematic diagram for this switch is anxious, and loam cake 13 is limited by the torsion spring 8 that is contained on the mandrel 10 with the opening angle of base 4.

For making anxious unlatching that stops detaining of this switch and lock operation convenient, feel quick-action sensitivity, the utility model is also to opening and the structure of lock part is done further to optimize to improve.Concrete scheme is that locking closure 21 is provided with button 18, chute push rod 19 is arranged on the button, be with spring 20 on the push rod, dead bolt 22, oblique projection 16 and spring 15 are arranged on the jam plate 17, dead bolt is positioned at the jam plate front end, and tiltedly projection and spring are positioned at the jam plate rear end, and jam plate is arranged in the jam plate groove 7 of loam cake, when being assembled into one, the chute of the chute push rod 19 on the button 18 part contacts with oblique projection on the jam plate 17.When emergency took place, external force was patted locking closure 21, and loam cake and base close up, on the outer button 14 of U-shaped that covers be inserted in button 5 in the U-shaped, jam plate 17 is under spring 15 effects simultaneously, its tongue inserts in U-shaped on the button 5, with loam cake and base pinning.At this moment, the stop button of control switch is depressed under the pressure of loam cake, and the machinery of being controlled is shut down.When emergency is removed, when needing to recover the control switch normal condition, use hand pressing button 18, move on the pushing jam plate tiltedly projection on the button in the chute body of chute push rod 19, move after making jam plate 17, its dead bolt 22 withdraws from button 5 in the U-shaped, loam cake and base are separated, recover nature.Present embodiment also in U-shaped button 5 above have " ∩ " shape hole 6, locking when opening for prohibiting, loam cake and base can't be opened.
