Abstract
An installation device working with a switch component, especially a switch knob, which is reset by a torsion spring contained in a space in the switch component and supported by one end of the spring on the body of the switch component and, when the switch component is moved, by one end of the spring on the body of the installation device or its casing. The space is bounded by a jacket of the component body, especially the switch knob which forms an engagement slot for the end of the spring supported on moving on the switch component in such a way that a supporting edge borders or is inclined upwards and downwards starting from a central position. A disappearing engagement recess is formed below on the supporting base for the torsion spring and the upper side of the engagement slot forms a further engagement recess of one of the ends of the torsion spring after a certain sector to tension the spring.
Description
The present invention relates to a kind of switch and a torsionspring is loaded on method on this switch.This switch by one particularly control crank carry out work, resetting of handle realize with a torsionspring, torsionspring is contained in the spring installation cavity on the switch.Spring rests on the Switch main body by a spring tip on the one hand, when switch deflection, rests on the erection unit body on the other hand by a spring tip, that is on its shell.
Said structure is well-known on principle, and an example is exactly the cup spring that is used on the car seat.This cup spring has the crimp up and down of bending, and it is placed in the space of a corresponding lower member, and turns over a predetermined angle and be placed in the corresponding space of upper member by the direction of rotation of upper member, sees US-A-4,642,432.Automatically needing an extra spending in the assembling process like this.
This class torsionspring is contained on the axle or in the installation cavity usually; In assembling process, this torsionspring must tighten by rotating, and adjusts then or also will locate.
The objective of the invention is to develop a kind of switch, it can reasonably finish the assembling of torsionspring in switch, particularly control crank.
By the present invention for achieving the above object, provide by means of the control crank switch that carries out work particularly, resetting of switch realizes with a torsionspring, torsionspring is contained in the spring installation cavity of switch, torsionspring rests on the Switch main body by a spring tip on the one hand, on the other hand when switch deflection, rest on erection unit body or its shell by a spring tip, it is characterized by: the spring installation cavity with switch particularly the overcoat of control crank be the boundary, put outward and be shaped on an extension spring otch, rest on the spring tip on the switch when being used for deflection, otch is made its side-strut and is tilted up and down from middle position, in the bearing bottom is that torsionspring is established a resilience hanging groove, hang the otch upside of spring and establish another hanging groove, after torsionspring was clamped to certain fan-shaped range, it was used for a spring tip of torsionspring.
So torsionspring can be assembled in switch according to the following steps: torsionspring places its installation cavity, and its upper spring termination is rested in above-mentioned another hanging groove by rotation.The shape of otch can guarantee that the lower spring termination slips in the hanging groove that matches with it.Switch and torsionspring have constituted a pre-assembled component together, have finished its work in the time of in erection unit that this assembly is packed into and have prepared, and need not further to adjust and the location.As long as make switch deflection by rotation, the upper spring termination just can be bearing in suitable position on the body of erection unit or its shell by its length or alternate manner.Under static state, do not need specially the upper spring termination to be suspended.In assembling process, the upper spring termination also can be clamped in the shell in advance by a sloping bearing surface.
By further design, extension spring otch on the torsionspring bearing changes a bearing-surface that is used for a spring tip beyond overcoat into, this bearing-surface is made the shape of rising, to be designed to back bending hook-shaped or can rest on the bearing-surface of this rising by other means the time when spring tip, the last lap of torsionspring is towards the bending of bearing direction, so each circle of torsionspring is drawn back each other, thereby can not influence the work of spring because of the friction between each circle.Obviously, the height of torsionspring has determined the degree of depth of installation cavity, and its height can slightly increase when spring stress clamped.
Can make step simply at the hanging groove of hanging spring otch upside, the upper spring termination changes in this groove after spring clamps.The clamping degree of spring can structurally pre-determine by the initial position of spring tip and the angle between the step.
The present invention can elaborate by means of the embodiment that schematically illustrates in the accompanying drawing.Wherein:
Fig. 1 is the part and the profile thereof that are arranged in the switch of erection unit, can see the switch of band torsionspring;
Situation after Fig. 2 switch takes out can be seen the extension spring otch of taking away behind the torsionspring;
Fig. 3 is corresponding to switch and the torsionspring vertical view of Fig. 1, and they are in preassembled sub-assembly state;
Torsionspring end view among Fig. 4 Fig. 2;
Torsionspring vertical view among Fig. 5 Fig. 4.
Erection unit 1 shown in Figure 1 has a switch 2 at least, and it is a control crank in this embodiment.Torsionspring 3 is housed on the switch 2, is used for resetting after the switch deflection.Torsionspring 3 is contained in the spring installation cavity 4, and this chamber is columniform in an embodiment, and it is the boundary with overcoat 5 and central axle 6.Spring tip 7 and 8 rests on switch 2 bodies, or rests on erection unit 1 body when switch 2 deflections.As shown in Figure 2, be shaped on one in the Switch main body and hang spring otch 9, rest on the spring tip 7 on the switch (being control crank) when being used for deflection here.Side-strut 10 tilts up and down from the middle position 11s.When the torsionspring of packing into, and after taking a fancy to spring tip from above and rotating counterclockwise, the lower spring termination slides to the bearing 12 of torsionspring 3 downwards, and slips in the resilience hanging groove 13.Press Fig. 1 and 3, hang spring otch 9 upsides, definite fan-shaped range is shaped on another hanging groove 14 according to clamping torsionspring.
The centre position 11 that hangs spring otch 9 can be selected like this, and promptly for the torsionspring do not fall into installation cavity fully when assembling at the bottom of, its lower spring termination can be slipped in the hanging groove 13.On the other hand, hanging the centre position 11 of spring otch 9 also can select deeplyer, therefore, even torsionspring has goed deep into also guiding by its upper spring termination in the installation cavity when assembling, go thereby only need the upper spring termination be inserted in another hanging groove 14 by rotation.
Hang the hanging groove 14 at spring otch 9 upside places and can make step simply, the upper spring termination can enter in the groove by this step when fastening spring.
According to further design, as shown in Figure 2, hang spring otch 9 and on torsionspring bearing 12, establish the bearing-surface 15 of a rising.Especially, this bearing-surface 15 can be outside the installation cavity overcoat, and it is downward-sloping that the back bending spring terminal of hook-type bends to the end circle track that makes torsionspring, so torsionspring is drawn back each other and clamps between two hanging grooves 13 and 14.By means of rising or bearing surface inclined 15, can also guarantee that the counter-force that acts on the upper spring termination 8 can not make torsionspring jump out when the pre-assembled component with switch and torsionspring formation is pressed in the erection unit from switch.Therefore, the last lap of torsionspring is pressed towards the installation cavity bottom.Torsionspring bearing 12 can design especially coarsely, so that improve its bed knife when torsionspring is placed erection unit.
Figure 4 and 5 have been represented the structure by the torsionspring 3 of embodiment.
