Abstract
The utility model relates to a novel plastic nut for an air-conditioner, which comprises a nut body prepared from a hard plastic material; the nut body has a hollow hexagonal structure with the top sealed; the bottom of the nut body is provided with a cylindrical body; the circular section of the cylindrical body is externally connected with the hexagonal section of the bottom of the nut body; an inner screw thread is arranged on the inner sidewall of the nut body; the inner sealed top of the nut body is fixed with an inversed U-shaped sealing gasket prepared from a rubber material; the edge of the bottom of the sealing gasket is matched with the top of the inner screw thread of the nut body; and the middle of the bottom of the sealing gasket is provided with a cylindrical lug boss, a platform or a hole. The novel plastic nut has the advantages that the nut is prepared from the hard plastic material, has good wearing property and also reduces cost for production and manufacture; the design of the rubber sealing gasket can keep good sealing performance under 5 MPa, can effectively reduce the loss of Freon for a long time and improve the comprehensive use performance and the service life of products.
Description
Technical field
The utility model relates to a kind of nut, especially a kind of air-conditioning equipment plastic nut.
Background technique
Be sealed with freon etc. in the air-conditioning equipment on the market, its sealing configuration joint is to fix by the nut that materials such as brass are made, and its sealability is relatively poor, in long-term use, cause the constantly losses such as freon in the air-conditioning, thereby influence the usability and the working life of air-conditioning.And, traditional brass nut processing difficulties, material is more expensive, has improved its cost of production greatly, is unfavorable for the popularization of product.
The model utility content
The purpose that the utility model relates to provides a kind of air-conditioning equipment plastic nut, to overcome the deficiency of existing product cost height, poor sealing performance.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of air-conditioning equipment plastic nut, the nut body that comprises the rigid plastics material, nut body is the hollow hexagonal structure of top seal, described nut body bottom is provided with the column type body, the circular cross-section of column type body is external in the hexagonal cross-section of nut body bottom, the nut body internal side wall is provided with internal thread, the inverted U-shaped sealing gasket of the interior sealing roof anchorage rubber material of nut body, the sealing gasket bottom margin cooperates with the internal thread top of nut body, and sealing gasket is provided with cylindrical end tangs or platform in the middle of the bottom.
Described air-conditioning equipment plastic nut can be provided with the hole in the middle of the sealing gasket bottom that nut body inside is being covered.
The beneficial effect of air-conditioning equipment plastic nut described in the utility model is: nut adopts the rigid plastics material to be made, and has greatly reduced manufacturing cost; Simultaneously, it is applicable to-10 ℃～50 ℃ Environmental Conditions, and it drops into flawless on the concrete floor from 2 meters eminences, is screwed into flawless on the joint with 12.5N-M moment; The design of rubber gasket makes it still can keep fabulous sealing under 5Mpa, loss that can permanently effective minimizing freon, the comprehensive usability and the working life of improving product.
