Lower coupler capable of positioning and supporting sealing gasket and coupler

Abstract

The invention discloses a lower coupler capable of positioning and supporting a sealing gasket. The lower coupler comprises a lower coupler main body, a sealing gasket and a sealing gasket limiting cover, wherein the upper side of the lower coupler main body is provided with a transverse wire duct and a longitudinal wire duct. An upper boss is formed between the longitudinal wire slot and the transverse wire slot; the sealing gasket covers the upper side of the lower coupler main body, and a lower convex transverse rib matched with the transverse wire duct and a lower longitudinal rib matchedwith the longitudinal wire duct are arranged at the lower side of the lower coupler main body; an upper groove position which is concave upwards and can be arranged on the upper boss in a sleeving mode to be positioned and supported by the upper boss is formed between the lower convex longitudinal rib and the lower convex transverse rib, and the sealing gasket limiting cover is arranged on the sealing gasket in a sleeving mode, detachably connected with the lower coupler main body and used for fastening the sealing gasket. The purposes of positioning, supporting and fastening the sealing gasket can be achieved, and therefore, the production efficiency can be greatly improved to meet the production delivery period. The invention further discloses a coupler comprising the lower coupler capable of positioning and supporting the sealing gasket.

Description

【Technical field】 [0001] The present application relates to the technical field of couplers, in particular to a lower coupler capable of positioning and supporting a gasket, and a coupler. 【Background technique】 [0002] At present, with the improvement of people's quality of life, healthy kitchen appliances such as wall breakers and soybean milk machines are becoming more and more popular. [0003] Existing couplers used in small household appliances such as wall breakers and soybean milk makers generally include a lower coupler and an upper coupler that is plugged and matched with the lower coupler. The lower coupler includes a lower coupler support, an insert spring card holder, insert spring, gasket, etc. However, the existing gasket assembled on the lower coupler support is prone to loosening and displacement, and there is also the problem that the gasket is not supported, which easily leads to quality problems Unqualified products will greatly reduce the rate of good ...
