Abstract
The utility model discloses a squirming pump head capable of adjusting flow, which comprises a press cover, a press block, a spring, wrenches, a transmission wheelset, a rolling shaft, a rolling wheel, a front blocking plate, a rear blocking plate, locating grooves and limiting blocks and is characterized in that two sides of the press cover are provided with the wrenches and the limiting blocks which are integrally connected and capable of freely rotating inside the press cover, the front blocking plate and the rear blocking plate are respectively provided with a locating groove, the limiting blocks can be locked in the locating grooves, the press block is arranged under the press cover, one end of the press block is connected with the press cover, and the spring is arranged between the other end of the press block and the press cover. The problem that the squirming pump head resolves is that (1) an elastic flexible tube is clamped between the press block and the rolling wheel, the pressure of the spring is adjustable, the press block can buffer tubes of different sizes, and accordingly flexible tubes with different caliber sizes can be pressed; (2) the front blocking plate and the rear blocking plate of the squirming pump head are made of aluminum materials so that when a motor drives the rolling shaft to rotate, the overall weight is small, and the effect of energy conservation can be achieved.
Description
Technical field:
The utility model relates to the peristaltic pump field, relates in particular to a kind of Wriggling Pump Head of can regulate flow.
Background technique:
Peristaltic pump is a kind of liquid transporting apparatus of may command flow velocity, and working principle is: elastic hose is installed between pressing plate and the roller, through roller repeated compression elastic hose the pipe medium is moved towards certain orientation; When roller rotates, form negative pressure between two extruding points of elastic hose, the solution extraction is elevated; Continuous-flow in pipeline, its flow velocity is by the diameter of elastic hose and the compression speed decision of roller rotation, because existing peristaltic pump pump head upper press cover is set to single radian; Gland can not be transferred; Can only press the elastic hose of equal bore, can't regulate elastic hose, Applicable scope is little.
Summary of the invention:
The utility model is to the deficiency of existing technology, provide a kind of simple in structure, be prone to mounting or dismounting, can regulate fluid flow, can be adapted to the Wriggling Pump Head of different bore elastic hoses.
For realizing above purpose, the technological scheme that the utility model adopts is:
A kind of Wriggling Pump Head of can regulate flow is made up of gland, briquetting, spring, spanner, transmission wheels, roller bearing, roller, front screen, backboard, locating slot, limiting stopper; Transmit the rear and front end of wheels front screen and backboard are installed, delivery wheel group switching centre position is provided with a roller bearing, but is provided with the free rolling roller in the equidistant position of transmission wheels periphery; It is characterized in that: the gland both sides are provided with spanner and limiting stopper, and spanner and limiting stopper connect as one, and can in gland, freely rotate, and respectively are provided with locating slot on front screen and the backboard, and limiting stopper can latch in the locating slot; The gland below is provided with briquetting, and an end and gland are connected, and are provided with spring between the other end and the gland.
Described front screen and backboard adopt aluminium material to make.
The soluble technical problem of the utility model is: (1) gland below is provided with briquetting, and an end and gland are connected, and are provided with spring between the other end and the gland; After peristaltic pump starts; Elastic hose is pressed and is clipped between briquetting and the roller, utilizes the adjustable in pressure of spring, and briquetting has buffer function to the pipe of different size; Can press the flexible pipe of different bore specifications like this, can guarantee that under equal conditions gland compresses the best radian of elastic hose; (2) the forward and backward baffle plate of Wriggling Pump Head adopts aluminium material, and motor is when driving the roller bearing rotation, and overall weight is lighter, reaches energy-conservation effect.
Description of drawings:
Fig. 1 is the utility model gland plan view;
Fig. 2 is the utility model gland construction profile;
Fig. 3 is the utility model assembled state figure;
Fig. 4 removes structural representation behind the gland for the utility model Wriggling Pump Head.
Embodiment:
As shown in the figure, a kind of Wriggling Pump Head of can regulate flow is made up of gland 1, briquetting 2, spring 3, spanner 4, transmission wheels 5, roller bearing 6, roller 7, front screen 8, backboard 9, locating slot 10, limiting stopper 11; Elastic hose is pressed and is clipped between briquetting 2 and the roller 7; Respectively be provided with locating slot 10 on front screen 8 and the backboard 9, gland 1 both sides are provided with spanner 4 and limiting stopper 11, and spanner 4 connects as one with limiting stopper 11; Can in gland 1, freely rotate, limiting stopper 11 can latch in the locating slot 10; During enforcement; Start peristaltic pump, drive roller 7 and rotate, elastic hose is pressed and is clipped between briquetting 2 and the roller 7; Utilize the adjustable in pressure of spring 3; The pipe of 2 pairs of different sizes of briquetting has buffer function, can press the flexible pipe of different bore specifications like this, can guarantee that under equal conditions gland 1 compresses the best radian of elastic hose.
The utlity model has the advantages such as flow of liquid in simple in structure, easy to operate, working stability, the can regulate pipeline, have great promotional value.
Claims (2)
1. the Wriggling Pump Head of a can regulate flow is made up of gland, briquetting, spring, spanner, transmission wheels, roller bearing, roller, front screen, backboard, locating slot, limiting stopper; It is characterized in that: the gland both sides are provided with spanner and limiting stopper, and spanner and limiting stopper connect as one, and can in gland, rotate, and respectively are provided with locating slot on front screen and the backboard, and limiting stopper can latch in the locating slot; The gland below is provided with briquetting, and an end and gland are connected, and are provided with spring between the other end and the gland.
