Technical Field

The utility model relates to an installation of water pump especially relates to a shock attenuation mounting structure of water pump, and this mounting structure can be applied to in the water heater.

Background

At present, a zero-cold-water heater does not produce cold water, can preheat cold water in a pipeline in advance, can enable comfortable warm water to flow out when a water tap is opened, namely the water heater can be started and heated, and does not need to wait when hot water is needed each time. Along with the increase of market demand of zero-cold water heaters, more and more users select to buy, and the quality of life and experience are improved. However, in the process of using the zero-cold water heater, the noise is large, and the experience of a user is influenced. The noise generated by the vibration of the water pump is a main noise source, and the friction generated by normal vibration or the noise caused by the vibration driving the whole machine not only influences the experience of a user, but also influences the service life of the water pump.

In order to reduce noise caused by vibration, the prior art also discloses some damping designs, see the Chinese utility model patent No. ZL201120170726.1, water pump damping device (No. CN 202073767U), and the patent mentions that positioning holes are symmetrically distributed on the upper cover plate; at least five rubber block guard rings are symmetrically distributed and fixed on the bottom surface of the upper cover plate and are fixedly connected with the upper cover plate into a whole; the rubber block guard ring is concentric with the positioning hole on the upper cover plate; the rubber block corresponding to the rubber block guard ring is correspondingly sleeved in the rubber block guard ring, and the rubber block higher than the rubber block guard ring is fixed on the upper cover plate through a bolt.

Can also refer to chinese utility model patent of patent number ZL201920478371.9 "a circulating pump damping structure and use its zero cold water heater (the grant bulletin number is CN 210070229U), this patent includes circulating pump, damping unit, installing support, and wherein the circulating pump is installed inside the water heater main part, the circulating pump sets up on the installing support, states damping unit and installing support and is connected, and covers at the circulating pump surface for reduce the vibration that the circulating pump during operation produced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to foretell technical current situation and provide a water pump shock-absorbing structure in addition.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: a water pump shock-absorbing structure comprises a pump body and is characterized by further comprising

The adapter plate is arranged at the bottom of the pump body, at least three flanges bent downwards are formed in the circumferential direction, and the bottom of each flange is provided with a hook part;

the bearing plate is positioned below the adapter plate and is provided with at least three raised connecting plates, each connecting plate is provided with a connecting hole or a connecting groove matched with the hook part, and the hook part can move up and down in the connecting hole or the connecting groove; each connecting plate is arranged corresponding to the respective flanging; and

the elastic piece is arranged between the adapter plate and the bearing plate and is positioned in an area surrounded by the flanging.

Considering stability, the adapter plate be circular, the turn-ups evenly arranges on the adapter plate.

Preferably, the elastic member is a spring.

The spring is a wire frame elastic piece, a first positioning part is arranged at the middle part of the adapter plate in a downward protruding mode, a second positioning part is arranged at the middle part of the bearing plate in an upward protruding mode, the upper end of the spring is sleeved on the first positioning part, and the lower end of the spring is sleeved on the second positioning part.

The bearing plate is provided with a boss part, and the connecting plate is formed on the boss part.

The connecting strength is further improved, and the flanging is wide at the upper part and narrow at the lower part.

Compared with the prior art, the utility model has the advantages of: the turn-ups on the keysets is in the same place with the connecting plate buckle on the loading board, and the elastic component is placed to the centre, and the assembly is accomplished promptly, and the assembly methods is simple reliable, and both are not the rigid connection again simultaneously, can effectively slow down water pump vibration noise through elastic component absorption vibrations.
