Novel central hot water circulation system

Abstract

The invention discloses a novel central hot water circulation system. The novel central hot water circulation system comprises a base frame, a transfer plate, a frame and a connecting head, wherein the transfer plate is rotationally installed on the base frame in a cooperating mode, the frame is fixedly installed on the transfer plate, and the connecting head is connected with the frame in a locking and cooperating mode; a plurality of assembling connecting bases are arranged in the left end face of the frame, inserting cavities are formed in the left side end faces of the assembling connecting bases, first electricity input heads are fixedly arranged on the inner walls of the right sides of the inserting cavities, first sliding connection cavities are symmetrically arranged in the upper inner wall and the lower inner wall of each inserting cavity, bevel edge locking blocks are installed in the first sliding connection cavities in a sliding fit mode, second sliding connection cavitiesare formed in the inner walls of the right sides of the first sliding connection cavities, a left sliding connection block and a right sliding connection block are arranged in every second sliding connection cavity in a sliding fit mode, and the parts, on the sides, in the second sliding cavities are provided with jacking springs in a jacking fit mode, wherein the sides are the sides, opposite toeach other, of every sliding connection block on the upper part and the corresponding sliding connection block on the lower part.

Description

technical field [0001] The invention relates to the technical field of hot water circulation, in particular to a novel central hot water circulation system. Background technique [0002] When the current hot water circulating pump is connected to electricity, the plug and socket on the hot water circulating pump are usually connected by friction fit. The use is unstable, and the service socket is always in a energized state. When plugged in and used, electric shock accidents are likely to occur, and the use risk factor is high. Therefore, it needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a novel central hot water circulation system for overcoming the above-mentioned defects in the prior art. [0004] According to a novel central hot water circulation system of the present invention, it comprises a base frame, an adapter plate rotatably mounted on the base frame, a frame fixedly installed on the adapter plate, and...
