Abstract
The utility model relates to a large flow card type pump head of a peristaltic pump, which belongs to the technical field of a liquid pump. The utility model is used for solving the problem of little conveying flow rate of a pump head of a peristaltic pump and comprises a pump body, a roller device, card devices and an elastic hose, wherein the elastic hose is wound on the excircle enveloping surface of a roller, and the card device touches and presses the elastic hose. After the utility model is improved, a right lock catch base and a left lock catch base are added and fixed to both ends of the pump body. The card devices are positioned on the right lock catch base and the left lock catch base and connected with the lock catch bases in a detachable mode. The utility model does not rely on the elastic deformation of cards to load the cards, so the stiffness of the cards can be increased greatly. Even if the cards and pressing blocks bear larger load and the elastic hose with larger wall thickness and inside diameter is loaded, the utility model is not easy to deform. Simultaneously, the pressure of the cards and the pressing blocks to the hose is adjustable, so the rotational speed of the roller can be enhanced, and the conveying in high volume is realized. Besides, the utility model has the characteristics of reliable card loading, convenient card loading, simple structure and easy operation.
Description
Technical field

Background technique
Peristaltic pump is a kind of displacement pump, uses in flowrate measuring tool, medical apparatus usually.It is made up of pump head, driver, and wherein pump head is made up of the pump housing, roller and elastic hose, and elastic hose is pressed on the roller by briquetting.During the work of peristaltic pump pump head, elastic hose is constantly pushed in the roller rotation, realizes the purpose of pumping liquid.Card type peristaltic pump pump head is meant that the roller outside is provided with briquetting and card, finishes the peristaltic pump pump head of liquid pumping function under the pressure effect of briquetting and card.Card generally can take off, and is installed on the pump housing behind the elastic hose that is installed again.At present, generic card chip peristaltic pump head mostly is and relies on the resiliently deformable of card (moulding) to realize being installed.Because card requires resiliently deformable, rigidity is less, so this type of card is limited to the pressure of elastic hose, peristaltic pump pump head rotating speed is lower, can not carry the liquid of big flow.In addition, because repeatedly the resiliently deformable of utilizing working of plastics is installed, and the position that is installed of card is subjected to the effect of alternate load during work, and after service time was long, card was easy to generate creep or fatigue ruption, and dismounting difficulty comparatively.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of mechanical structure card that is installed that utilizes is provided, thereby the thicker elastic hose that can be installed is to improve the big flow card type peristaltic pump pump head of feed flow.
The alleged problem of the utility model is realized by following technological scheme:
A kind of big flow card type peristaltic pump pump head, comprise the pump housing, rotary roller, card-type device and elastic hose in the formation, elastic hose is on roller cylindrical envelope surface, card-type device presses elastic hose, its specialization is: set up left and right sides snap close seat 12, left and right sides snap close seat is fixed on the pump housing 9 two ends, and described card-type device is positioned on the snap close seat of the left and right sides, forms detachable the connection with the snap close seat.
Above-mentioned big flow card type peristaltic pump pump head, described card-type device is by card 3, briquetting 6 and adjust screw 4 and forms, and wherein card and briquetting are hinged by briquetting fixing pin 2, and the adjustment screw is positioned on the card, touch briquetting.
Above-mentioned big flow card type peristaltic pump pump head, a described snap close seat is provided with snap close 10 and elastomer 8, and snap close and snap close seat are hinged by snap close fixing pin 11, and elastomer 8 is positioned at snap close 10 sides and contacts with it, and the snap close end is provided with the snap close clasp.
Above-mentioned big flow card type peristaltic pump pump head, the described pump housing is provided with card fixing pin 1, and described card two ends are provided with arc groove 14 and clasp groove 15, and wherein arc groove and card fixing pin fasten, and clasp groove and snap close clasp fasten.
Above-mentioned big flow card type peristaltic pump pump head, described snap close seat is provided with positioning boss 13, and described card is provided with the positioning groove 17 that is complementary with positioning boss.
The utility model improves at the drawback that generic card chip peristaltic pump head relies on the realization of card resiliently deformable to be installed, set up mechanical chucking device, it does not rely on the resiliently deformable of card to be installed, therefore can improve the rigidity of card itself greatly, even card and briquetting bear big load, the relatively thick that is installed, than the elastic hose of large diameter, also be difficult for deforming, card and briquetting are to the adjustable in pressure of flexible pipe simultaneously, therefore can improve the rotary roller rotating speed, be achieved and carry big flow, and it is reliable to be installed, and it is convenient to unload card.The utility model is simple in structure, reasonable in design, be easy to realize, is suitable for promoting.
