Abstract
The utility model relates to a dustproof device for a temperature controller, comprising a housing, an energized contact and a regulating push rod in the housing, wherein the housing comprises a lower cover and an upper cover which is matched with the lower cover, the regulating push rod has a cylindrical structure, the upper cover is provided with a hollow conic boss which is used for installing the regulating push rod and in a conical shape, the regulating push rod is provided with a circular blocking piece which is matched with an upper end face of the hollow conic boss, and the upper cover and the lower cover are clamped into a whole through a clamping structure. According to the dustproof device of the utility model, by arranging the hollow conic boss and the regulating push rod with the cylindrical structure, the regulating push rod can be connected with the hollow conic boss through a circular contact surface, thus a gap therebetween can be reduced; and by arranging the circular blocking piece, fine granules (such as dusts) in the air can be prevented from easily entering into the temperature controller to cause poor conduction of the contact, thereby prolonging service life of the temperature controller, ensuring conduction of the energized contact, reducing maintenance cost of enterprises, and raising working efficiency.
Description
Technical field
The utility model relates to a kind of dust guard, what be specifically related to is that a kind of temperature controller is used dust guard.
Background technology
Temperature controller is a kind of control instrument of extensive use, has a variety ofly as temperature controlled instruments at present, installs and uses the electronic applications at refrigerator, air-conditioning and automobile as the one of which.Existing temperature controller is provided with the push rod of end control wet contact, and this push rod is the square structure, is processed with the square opening suitable with this push rod at the loam cake of temperature controller, is convenient to push rod and installs.And the push rod of this structure is owing to need activity; Thereby and the square opening of loam cake between leave the gap; But it is inner to get into the temperature air device easily through the fine particle (for example, dust) in the clearance air, causes the wet contact loose contact; Influence the use of temperature controller, shortened its useful life.
The utility model content
For overcoming the deficiency that exists on the prior art, the utility model purpose is to be to provide a kind of good water-proof effect, simple in structure and the temperature control dust guard that improves useful life.
To achieve these goals, the utility model is to realize through following technical scheme:
Temperature controller is used dust guard, comprises wet contact and regulation and control push rod in the shell, shell, said shell comprise lower cover and with the suitable loam cake of lower cover; It is characterized in that; Said regulation and control push rod is a cylindrical structural; Be covered with on said and be used for installing the regulation and control push rod; And be conical hollow cone boss, and said regulation and control push rod is provided with and the suitable circular block piece in hollow cone boss upper surface, and it is one that said loam cake engages through snap-in structure with lower cover.
Temperature controller according to above-mentioned is used dust guard, and wherein, said snap-in structure comprises and be arranged on the buckle that covers and be arranged on down the bayonet socket that covers, and fastens through buckle and bayonet socket loam cake and lower cover are connected as a single entity.
The utility model is set to cylindrical structural through the hollow cone boss being set and regulating and control push rod; Make between regulation and control push rod and the hollow cone boss to be connected, dwindled gap between the two, and pass through circular block piece through circular contact-making surface; (for example prevented airborne fine particle; Dust) gets into temperature air device inside easily and cause the contact poor flow, increased the useful life of temperature controller, guaranteed the conducting of wet contact; Reduce the maintenance cost of enterprise, improved operating efficiency.Make its convenient disassembly through snap-in structure simultaneously, stable installation, it is simple in structure, and is easy to use, is worth of widely use.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment;
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the superstructure sketch map of the utility model;
Fig. 3 is the structural representation of the regulation and control push rod of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
Embodiment:
Referring to Fig. 1; The utility model provides a kind of dust entering temperature controller temperature inside controller of avoiding and uses dust guard; Comprise the shell, the wet contact in the shell and the regulation and control push rod 130 that are arranged on the temperature controller outside, this shell comprise lower cover 120 and with the suitable loam cake 110 of lower cover 120; Said regulation and control push rod 130 is a cylindrical structural; Its cross section is circular; Be provided with at said loam cake 110 and be used for installing regulation and control push rod 130, and be conical hollow cone boss 111, the center of this hollow cone boss 111 is provided with centre bore 113; Regulation and control push rod 130 passes centre bore 113 and is installed on the loam cake 110, and this regulation and control push rod 130 closely contacts with centre bore 113 inwalls; On the regulation and control push rod 130 above the centre bore 113, be fixed with circular block piece 131; This circle block piece 131 is suitable with hollow cone boss 111 upper surfaces; (for example prevented airborne fine particle; Dust) gets into temperature air device inside easily and cause the contact poor flow, increased the useful life of temperature controller, guaranteed the conducting of wet contact.
In the present embodiment; It is one that loam cake 110 engages through snap-in structure with lower cover 120; This snap-in structure comprises the buckle 112 that is arranged on the loam cake 110 and is arranged on the bayonet socket on the lower cover 120; Through buckle 112 and bayonet socket fastening its loam cake 110 is connected as a single entity with lower cover 120, makes its convenient disassembly, stable installation.
The loam cake 110 and the hollow cone boss 111 of present embodiment are the disposal pouring moulding, and regulation and control push rod 130 is the disposal pouring moulding with circular block piece.
The utility model is set to cylindrical structural through hollow cone boss 111 being set and will regulating and control push rod 130; Make between regulation and control push rod 130 and the hollow cone boss 111 to be connected, dwindled gap between the two, and pass through circular block piece 131 through circular contact-making surface; (for example prevented airborne fine particle; Dust) gets into temperature air device inside easily and cause the contact poor flow, increased the useful life of temperature controller, guaranteed the conducting of wet contact; Reduce the maintenance cost of enterprise, improved operating efficiency.Pass through snap-in structure simultaneously
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined
