Description
Technical field
This utility model relates to potentiometer field, particularly relates to a kind of potentiometer with the sealant of resistance to flatulence of heat type.
Background technology
Potentiometer be there are three exits, resistive element that resistance can be regulated by certain Changing Pattern, potentiometer is generally made up of resistive element and moveable brush.Potentiometer is installed in various equipment enterprising enforcement use, plays regulation effect, existing rotational potentiometer poor sealing performance, sealant resistance to flatulence of heat type poor performance, hot environment can not be born, cause dust, steam etc. to enter inside potentiometer, the service life of potentiometer can be reduced.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of potentiometer with the sealant of resistance to flatulence of heat type, and good seal performance, sealant can bear serious thermal expansion, and service life is long.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of potentiometer with the sealant of resistance to flatulence of heat type, it is characterized in that, including: lower house, upper shell, described upper shell top is provided with axle sleeve, a circle graphite encapsulation layer it is provided with on described axle sleeve inner surface, described graphite encapsulation layer surface configuration has a resistance to flatulence of heat type coating, a cavity is formed between described lower house and upper shell, described cavity inside is provided with rotating shaft, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described rotating shaft matches with described axle sleeve, described rotating shaft includes metal inside and non-graphite outer layers, the first described fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
In one preferred embodiment of this utility model, described graphite encapsulation layer material is expanded graphite.
In one preferred embodiment of this utility model, the described compounding substances that resistance to flatulence of heat type coating is mullite, silicon and boron carbide.
In one preferred embodiment of this utility model, described resistance to flatulence of heat type coating is sprayed by dry heat treatment.
In one preferred embodiment of this utility model, between described graphite encapsulation layer and axle sleeve, and it is connected by epoxide-resin glue is gluing between metal inside with non-graphite outer layers.
The beneficial effects of the utility model are: potentiometer good seal performance provided by the utility model, and sealant can bear serious thermal expansion, and service life is long.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of potentiometer one preferred embodiment with the sealant of resistance to flatulence of heat type of this utility model；
In accompanying drawing, the labelling of each parts is as follows: 1-lower house, 2-upper shell, 3-axle sleeve, 4-graphite encapsulation layer, 5-resistance to flatulence of heat type coating, 6-rotating shaft, 7-metal inside, 8-non-graphite outer layers.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of potentiometer with the sealant of resistance to flatulence of heat type, it is characterized in that, including: lower house 1, upper shell 2, described upper shell 2 top is provided with axle sleeve 3, it is provided with a circle graphite encapsulation layer 4 on described axle sleeve 3 inner surface, described graphite encapsulation layer 4 surface configuration has a resistance to flatulence of heat type coating 5, a cavity is formed between described lower house 1 and upper shell 2, described cavity inside is provided with rotating shaft 6, conduction revolving fragment, first fixed pin sheet, second fixed pin sheet, dynamic pin sheet and circular arc resistance body, described rotating shaft 6 matches with described axle sleeve 3, described rotating shaft 6 includes metal inside 7 and non-graphite outer layers 8, the first described fixed pin sheet and the second fixed pin sheet are connected to the two ends of circular arc resistance body.
Described graphite encapsulation layer 4 material is expanded graphite, and expanded graphite in addition to having the characteristics such as the chemical stability of native graphite, anti-erosion, also has special flexibility and elasticity also known as soft graphite, this graphite, is a kind of preferably encapsulant.
The described compounding substances that resistance to flatulence of heat type coating 5 is mullite, silicon and boron carbide, this coating can not only be born serious flatulence of heat type, also be had stronger oxidation resistance.
Described resistance to flatulence of heat type coating 5 is sprayed by dry heat treatment.
Between described graphite encapsulation layer 4 and axle sleeve 3, and it is connected by epoxide-resin glue is gluing between metal inside 7 with non-graphite outer layers 8.
Potentiometer good seal performance provided by the utility model, sealant can bear serious thermal expansion, and service life is long.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
