Description
Technical field
The present invention relates to a kind of cylindrical shell of annular, have a cannelure that is used to hold a torsionspring, be used in particular for a step switch or a potentiometer.
Background technology
By the application of the known torsionspring of DE 33 07 827 A1 in a potentiometer.Spindle guide at potentiometer is fixed a torsionspring on device, in the pin in its embedding potentiometer shaft, wherein torsionspring makes the potentiometer of deflection get back to a predetermined neutral position.Two leg radial fingers of torsionspring to the outside and around a pin, this pin is connected with the knurled wheel that is used for regulator potentiometer.Torsionspring is fixedlyed connected with the potentiometer bearing, thereby the tensioning torsionspring leg also produces a tension force thus when knurled wheel rotates, and it retracts original position with knurled wheel again.For torsionspring is installed it is moved and gapless cooperation on its pin at knurled wheel under the situation of the leg spacing of a corresponding selected torsionspring is possible along the potentiometer bearing.
Open another kind of adjustable resistor among the DE 34 44 229, it has a helical spring that is used to reset.The resistor that this is adjustable has a rotor, and it has the hollow cylinder rotor wall of the axially parallel of at least two overlapped settings.Hollow cylinder tegmental wall at least two overlapped settings of fixing lid on a lower housing portion of interlocking between these rotor wall.Between two tegmental walls of rotor and lower housing portion, there is an annular space.A helical spring is set therein, and it is fixed on the one end and covers and be fixed on the rotor with its other end.This helical spring is used for resetting of rotor.When helical spring is installed, be inserted in the annular space of lid and advance in the rotor.
Summary of the invention
The objective of the invention is to, the cylindrical shell of the another kind of annular of exploitation inserts and installs torsionspring therein easily in order to hold a torsionspring.
According to the present invention, this purpose reaches like this, be about to cylindrical shell that torsionspring inserts an annular for example in the cannelure of a potentiometer, this housing comprises an external groove sidevall and an internal groove side wall, external groove sidevall has a groove, in order to hold the top leg of torsionspring, its middle shell is provided with the groove that an axioversion extends downwards, in order to hold the following leg of torsionspring, make torsionspring after insertion, cling on the groove that axioversion extends downwards below the pre-tensioning simultaneously radial and axial tensioning of leg by being undertaken by top leg.Having axial being provided with of groove on directed inclined-plane downwards by this provides possibility now, in the housing of torsionspring can being packed into fast and simply and simultaneously by assembling its radial and axial pre-tensioning.The end that leg on the inclined-plane below torsionspring is adjacent to is provided with a block, thereby according to the setting of this block, in internal groove side wall or external groove sidevall, torsionspring can be provided with any pre-tensioning.Produce another advantage thus, thus the perdurabgility when promptly not needing independent job step and shortening assembling for pre-tensioning.
Description of drawings
Below by an embodiment the present invention is described.Wherein:
The basic structure of an embodiment of Fig. 1 housing of the present invention comprises a torsionspring and direction of engagement thereof;
The installation of Fig. 2 a to 2d torsionspring in housing.
Embodiment
Torsionspring 8 has the leg 9,10 of two back-flexings.Shang Mian leg 9 is radially outward crooked and following leg 10 radially curves inwardly in this embodiment.The length of leg 9,10 is restricted according to their function.The length of following leg 10 roughly accords with the thickness of internal groove side wall 3.The top leg 9 of torsionspring 8 is longer than the thickness of cell wall 2, thereby top leg 9 protrudes from outside the external groove sidevall 2.Therefore leg 9 protrudes from the terminal of external groove sidevall 2 can clamp and produce a torque by a pusher dog.
Combination according to housing 1 of the present invention and torsionspring 8 can for example be applied in the potentiometer or step switch that is not shown in further detail.Leg above this 9 is produced a more or less big torque according to the pre-tensioning of torsionspring 8 in housing 1.Because the present invention is applied in the manual switch mostly, this employing is had the torsionspring 8 of spring characteristic curve that would rather be smooth.Its objective is, in whole adjustable range, on knob, produce a moment as far as possible uniformly.
The length of cylindrical housings 1 is equivalent to the axial length of torsionspring 8 basically, and wherein, housing 1 can protrude from outside the torsionspring 8 in some zones.Particularly the lengthening at the regional inner housing 1 of block 6 is significant, so that the leg 10 reliably below the guiding.The average diameter of torsionspring 8 is about 15mm, but this and do not mean that the present invention is defined on this size.Adopting the housing 1 that is used to hold torsionspring 8 of the present invention in the switch with large scale or executive component is imaginabale equally.
According to Fig. 1, the direction along arrow P is inserted the cannelure 4 of housing 1 from top with torsionspring 8.Other erection sequence is shown among Fig. 2 a to 2d.Leg 9 above after torsionspring 8 inserts housings 1 be bearing on the external groove sidevall 2 and below leg 10 be adjacent to the groove of internal groove side wall 3.Need only be for the pre-tensioning of torsionspring 8 along the direction of arrow, in this embodiment, the top leg 9 of counter-clockwise direction traction torsionspring 8 is as shown in Fig. 2 b.Thereby leg 10 and the quilt axially pre-tensioning of this moment below inclined-plane 5 guiding.In case the block 6 that following leg 10 arrives on the internal groove side wall 3 just finishes axially pre-tensioning, as shown in Fig. 2 c.By torsionspring 8 by top leg 9 on external groove sidevall 2 above a kind of further tensioning of rotation of direction of groove, now, torsionspring is by radially pre-tensioning.Fig. 2 d illustrates state and the position of torsionspring 8 in housing 1 that assembles.The top leg 9 of torsionspring 8 is arranged in the groove 7 of external groove sidevall 2 now.Groove 7 here can change at one 25 ° to 65 ° angular range, and the angle of preferably making one 45 ° is as the sphere of action of top leg 9 in external groove sidevall 2 of torsionspring 8.
The present invention can be used for resetting of a kind of rotational motion, but it also can produce a torque on an executive component, thereby passes on a thoughts and feelings that is used for the adjustment movement of the switch of rotatable adjusting or potentiometer for the operating personnel of keying.The present invention can for example be that a multiple-pole switch is as restriction or end stop about torque with a thin draw-in groove or the thick combined use of draw-in groove or in the terminal of a draw-in groove section also.
Example shown in Fig. 1 and 2 is only represented one embodiment of the invention.Same imaginabale is to make the groove of axioversion extension downwards and also operate by means of a torsionspring 8 under the radially outward directed situation of two legs 9,10 thus in outer annular groove.
