Abstract
The utility model relates to a peristaltic pump, in particular to a peristaltic pump head with an elastic compression-type installation handle, which comprises a pump case, a press block and a protective cover, one end of the protective cover is fixed on the pump case through a fastening knob, the other end of the protective cover is provided with an open groove, and the groove opening is pressed on the press block through the elastic compression-type installation handle arranged on the press block. The protective cover of the pump head adopts the joint positioning way of the fastening knob and the elastic compression-type installation handle, which has the advantages that: 1. the protective cover can be more easily and conveniently installed, and scratch can not occur during installation; 2. the protective cover is tightly attached to the press block under the action of the elastic compression-type installation handle, so the pump head can not have vibration and noise due to the gap during running.
Description
Technical field
The utility model relates to a kind of peristaltic pump, especially relates to a kind of peristaltic pump pump head with elastic compression formula mounting knob.
Background technique
Peristaltic pump is a kind of of precision pump, and it mainly is made up of pump head, driver and elastic hose.Pump head includes constituent elements such as pump case, briquetting assembly, roller assembly, and during peristaltic pump work, the roller assembly of pump head is turned round by driver drives.Therefore, pump case need provide the protective zone of a sealing for the roller assembly, the Security when guaranteeing to move.The pump case of present small-sized peristaltic pump pump head is normally processed case type, is pump case and the mode of face guard combination but the peristaltic pump pump head of big flow adopts usually, with the sealing protective zone of formation roller assembly.Removable face guard has made things convenient for the user to operations such as the replacing of each parts in the pump case, dismounting, maintenances, and this means of fixation on pump case of face guard has determined the comfort level of user to its dismounting operation.In existing similar products at home and abroad, what face guard fixing adopted mostly is the mode that tightening knob combines with spacing catch (positive stop).This means of fixation is comparatively simple; But there is following defective: 1. when face guard is installed; Must earlier the front side of face shield be inserted by in the clearance groove that forms between spacing catch and the briquetting,, therefore have the deviation error then to be prone to cause face shield to be scratched during insertion slightly by catch because clearance groove is very narrow; 2. after face guard is installed; Spacing catch only plays the effect of general location to face guard reality; But it is not pressed in briquetting fully, so can has the gap between face guard and spacing catch and the briquetting, when pump head moves; Face guard just can produce vibration and noise, and long-term vibration might cause then that tightening knob gets loose, face guard comes off.
The model utility content
The technical problem that the utility model will solve is: for the face guard that solves present peristaltic pump pump head owing to the face guard that adopts tightening knob to combine the mode of location to exist with spacing catch (positive stop) be installed inconvenience, be prone to be scratched, to exist change the card gap when causing the pump head operation generation vibrate and the problem of noise, a kind of peristaltic pump pump head with elastic compression formula mounting knob is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of peristaltic pump pump head with elastic compression formula mounting knob; Include pump case, briquetting, face guard; One end of face guard is fixed in pump case through tightening knob; The other end of face guard is provided with opening slot, and the notch place is pressed in briquetting by the elastic compression formula mounting knob location that is installed on briquetting.When the dismounting face guard, back out tightening knob earlier, elastic compression formula mounting knob is pulled outwardly, can take off face guard this moment; During installation; Earlier elastic compression formula mounting knob is pulled outwardly; Then with the face guard assigned position (form the bigger gap that is installed because elastic compression formula mounting knob is pulled outwardly the back with briquetting, so face guard is easy to insert this gap that is installed, and can be scratched) of packing into; Unclamp elastic compression formula mounting knob again, tighten tightening knob simultaneously.Elastic compression formula mounting knob can be pressed in briquetting with this end of face guard.
Say further; Described elastic compression formula mounting knob is mainly by screw, sliding sleeve, stage clip and compress handle and form; On briquetting, be provided with the mounting hole of elastic compression formula mounting knob; The screw of elastic compression formula mounting knob and sliding sleeve are inserted in the mounting hole and the screw head end is fastened to briquetting, and the front end that compresses handle compresses the notch place of face guard.
For the sliding sleeve that the prevents above-mentioned elastic compression formula mounting knob phenomenon that rotates, on sliding sleeve, have spacing guiding groove, have pin-and-hole in the side position of mounting hole, be provided with the spacing guide finger that matches with spacing guiding groove in the pin-and-hole.Spacing guide finger is worn to the spacing guiding groove of sliding sleeve by pin-and-hole, prevents that sliding sleeve from rotating, and plays leading role moving axially of sliding sleeve simultaneously in the process.
The beneficial effect of the utility model is: this has the peristaltic pump pump head of elastic compression formula mounting knob; Its face guard is by tightening knob and elastic compression formula mounting knob co; Wherein elastic compression formula mounting knob has replaced the spacing catch (positive stop) of present employing; The advantage of this orientation type of face guard is: 1. the installation of face guard is more easy, convenient, does not have the problem that is scratched during installation; 2. face guard keeps being close to briquetting under the effect of elastic compression formula mounting knob; When pump head moves, can not cause noise and vibration, and avoid the get loose problem of tightening knob because of possibly cause by long-term vibration of fixed protection face shield because of there being the gap.
