Description

A kind of duplex peristaltic pump with positive and negative clutch
Technical field
The utility model relates to a kind of liquid delivery pump, particularly a kind of duplex peristaltic pump with positive and negative clutch.
Background technique
Liquid delivery pump is mainly used in liquid auxiliary on the electric equipment such as washing machine filling and the transfer pump carried automatically, is mainly rotated by parts such as motor actuation gears, drives the variation of related volume, produces to draw and the function of compression output.
Existing liquid charging method respectively is to drive the one-way pump body action by motor respectively by the overrunning clutch clockwise and anticlockwise, realize the independent pouring functions that adds respectively, wherein a kind of overrunning clutch is to be finished by similar structure such as the helical teeth shape of two groups of unidirectional delivery torques and springs, in use because of the effect of spring, the one side of not transmitting torque can produce bigger noise.And existing inside and outside silicone tube is with after joint is connected, and all adopts mode such as larynx hoop to tighten silicone tube, prevents from coming off, and not only the part amount is many for this mode, and the cost height.
The model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, and physical dimension is little, the duplex peristaltic pump with positive and negative clutch that noise is low and cost is low.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of duplex peristaltic pump with positive and negative clutch, comprise the pump case that is constituted by loam cake and lower cover, direct current generator, worm and worm wheel, described direct current generator is arranged in the pump case, and described direct current generator running shaft is connected with worm screw, described worm screw and described worm gear through arranging on the worm screw screw thread and worm gear on the gear teeth meshing that arranges, it also comprises overrunning clutch body and following unidirectional clutch body, described upward overrunning clutch body and described unidirectional clutch body down are arranged at described worm gear both sides respectively, and the lug boss that last overrunning clutch body one side and described unidirectional clutch body one side down and described worm gear both sides arrange is in transmission connection, described upward overrunning clutch body opposite side and described unidirectional clutch body opposite side down are equipped with the complex root pressure ram, described overrunning clutch body and the described unidirectional clutch body down gone up is connected with time fixedly connected with last fixedly connected through pressure ram respectively, the circle cover is all arranged on the described complex root pressure ram, be with interior silicone tube outside described a plurality of circle cover, silicone tube all is connected wherein said fixedly connected in described two with the silicone tube joint, described fixedly connected down, described worm gear, described upward overrunning clutch body and described unidirectional clutch body down all are fixed in the pump case by a plug.
Preferably, described upward overrunning clutch body opposite side and described unidirectional clutch body opposite side down are equipped with three pressure rams, and evenly distribute.
Preferably, described loam cake and described lower cover adopt locking nut to fix.
Preferably, also be provided with the silicone tube compact heap between the described second silica gel pipe joint, the pressure that described interior silicone tube and described silicone tube joint are connected through screw cooperates the silicone tube compact heap, by pretension described interior silicone tube and described silicone tube joint is tightened.
Preferably, described upward overrunning clutch body and described unidirectional clutch body down are provided with clutch post and the thin slice elastic support of five equilibrium, and the inclined-plane that is used for arranging with last overrunning clutch body or down unidirectional clutch body cooperates.
Power supply divides two kinds of patterns for the VDC of direct current generator: a kind of is normal power supply, and direct current generator is just changeed; Another kind is that power supply polarity is opposite, makes the direct current generator counter-rotating.
When the direct current generator connection is just being changeed, the clutch post of the five equilibrium that one of them overrunning clutch body arranges cooperates with the inclined-plane of setting, realize the function of monolateral connection, this overrunning clutch body is rotated, another overrunning clutch body then is in slipping state, so have only single peristaltic pump work this moment.When direct current generator was connected counter-rotating, the working state exchange of two single-phase clutch bodies made another peristaltic pump work.Wherein, two kinds of patterns can not be worked simultaneously.
Compared with prior art, the beneficial effects of the utility model are: reduce the product structure size, reduce the product complexity, and reduce the product actual cost, the noise during more obvious reduction product uses promotes and uses impression and image product.
