Abstract
The utility model relates to spring art, be specifically related to a kind of squash type variable resistance spring, the support that it comprises the jack-post on base plate, base plate and is connected with base plate, resistance spring, slide plate and nut is socketed with successively above described jack-post, described pedestal upper end is provided with contiguous block, described contiguous block side is connected with contact pilotage, and described contact pilotage is connected with resistance spring edge, and described jack-post is provided with screw thread.The features such as the effect of its employing resistance spring of the utility model and slide plate, can change its length by extruding slide plate, reach the effect of variable resistance value, play the effect of slide rheostat, and it have easy to use, simple to operate, practical.
Description
Technical field
The utility model relates to spring art, is specifically related to a kind of squash type variable resistance spring.
Background technology
Slide rheostat is part, and it by changing the resistance of self, thus can play the effect of control circuit.In circuit analysis, slide rheostat both can as a fixed value resistance, also can as a resistance-changing resistor.The formation of slide rheostat generally comprises five parts such as binding post, slide plate, resistance wire, Metallic rod and porcelain cylinder.In actual application, resistance wire adopts thread forms to be wrapped on porcelain cylinder, and because this resistance wire that fixedly makes greatly reduces its result of use, and resistance wire very easily damages.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, there is provided a kind of structure simple, a kind of squash type variable resistance spring reasonable in design, easy to use, it adopts the effect of resistance spring and slide plate, can change its length, reach the effect of variable resistance value by extruding slide plate, play the effect of slide rheostat, and it has easy to use, simple to operate, the feature such as practical.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of squash type variable resistance spring described in the utility model, the support comprising the jack-post on base plate, base plate and be connected with base plate, resistance spring, slide plate and nut is socketed with successively above described jack-post, described pedestal upper end is provided with contiguous block, described contiguous block side is connected with contact pilotage, described contact pilotage is connected with resistance spring edge, and described jack-post is provided with screw thread.
Wire casing is provided with in described base plate.
Described jack-post and slide plate adopt insulating material.
After adopting said structure, the utility model beneficial effect is: the effect of its employing resistance spring of the utility model and slide plate, its length can be changed by extruding slide plate, reach the effect of variable resistance value, play the effect of slide rheostat, and it has easy to use, simple to operate, the feature such as practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, floor; 2, resistance spring; 3, nut; 4, jack-post; 5, slide plate; 6, support; 7, contact pilotage; 8, contiguous block; 9, wire casing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of squash type variable resistance spring described in the utility model, the support 6 comprising the jack-post 4 on base plate 1, base plate and be connected with base plate 1, described jack-post 4 is socketed with resistance spring 2, slide plate 5 and nut 3 above successively, described support 6 upper end is provided with contiguous block 8, described contiguous block 8 side is connected with contact pilotage 7, and described contact pilotage 7 is connected with resistance spring 2 edge, and described jack-post 4 is provided with screw thread.
Wire casing 9 is provided with in described base plate 1.
Described jack-post 4 adopts insulating material with slide plate 5.
The utility model in use, slide plate applies a power, by spring compresses, resistance spring between contact pilotage and base plate is increased, also makes the resistance value between contact pilotage and base plate increase, fast and easy, meanwhile, change common slide rheostat easily to slide impaired defect.
The features such as the effect of its employing resistance spring of the utility model and slide plate, can change its length by extruding slide plate, reach the effect of variable resistance value, play the effect of slide rheostat, and it have easy to use, simple to operate, practical.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
