Pull ring handle construction with rigid plastic seal

Abstract

The invention relates to the technical field of vehicle air conditioners, in particular to a pull-ring handle structure of a hard plastic seal. It includes a ring-shaped hollow ring body, the first sealing plug and the second sealing plug in the ring body are both closed at one end and open at the other end, and are fixed to the inner wall of the ring body through connecting ribs, and the ring body is built in A number of bolt screw-in holes are opened between the first sealing plug and the second sealing plug, and a flexible bending part is provided on the side where the pull ring body is placed on the second sealing plug, and the flexible bending part and the pulling ring Convex points are provided at the connecting parts between the main bodies. The handle of the pull ring has a beautiful appearance, and the structure is relatively concealed so that it is not easy to bump into each other. The bump structure can ensure that the product can be easily removed; there is no hidden danger of scratching the operator, which can reduce the weight of the product, and the handle of the pull ring is on the same plane as the product installation surface, and the product mold Only one pair of upper and lower molds is needed, which is conducive to cost control.

Description

technical field [0001] The invention relates to the technical field of vehicle air conditioners, in particular to a pull-ring handle structure of a hard plastic seal. Background technique [0002] In the field of automotive parts processing technology, important parts such as evaporators and condensers need to be sealed to the expansion valve connected to them before they are assembled after processing. The existing seals generally use hard plastic seals. The appearance of the product is affected by the overhanging size of the handle. At the same time, employees are easily scratched by the edge of the handle when operating, and they bump into each other during transportation and cause it to fall off. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the object of the present invention is to provide a pull ring handle structure of a hard plastic seal. [0004] In order to achieve the above object, the technical solution adopted...
