Description

Peristaltic pump capable of preventing motor shaft from slipping Technical Field The utility model relates to the technical field of peristaltic pumps, in particular to a peristaltic pump capable of preventing a motor shaft from slipping. Background Peristaltic pumps are positive displacement pumps that deliver fluid by compressing a flexible hose, which operate on a principle similar to squeezing a fluid filled hose with a finger, as the finger slides forward, and the fluid in the tube moves forward. The peristaltic pump is rotated by a driving shaft of a motor, the driving shaft rotates by driving rollers, and then the rollers sequentially squeeze the elastic hose to form continuous compression-release circulation, so that negative pressure is generated in the hose, and fluid is pushed to flow unidirectionally. The peristaltic pump needs to use a motor, a bearing of the motor contains lubricating oil, and when the motor is assembled, a driving shaft of the motor passes through the bearing, so that the lubricating oil is arranged on the driving shaft. When the motor runs, lubricating oil of the bearing can be permeated into the driving shaft, so that the driving shaft and the wheel slide, the motor idles, and the product is invalid. Disclosure of utility model In view of the shortcomings of the prior art, the present utility model aims to provide a peristaltic pump capable of preventing a motor shaft from slipping, so as to solve the problems mentioned in the background art section. The utility model is realized by the following technical scheme: The peristaltic pump comprises a mounting shell, a motor, a driven shaft and a driven shaft, wherein the motor is fixedly arranged on the mounting shell and is provided with a driving shaft, the mounting shell is provided with a mounting groove, a plurality of rollers are arranged in the mounting groove, a hose is clamped between the groove wall of the mounting groove and the rollers, two ends of the hose penetrate out of the mounting shell, the driven shaft is connected with the driving shaft in a split mode, and the driven shaft is embedded in the lower end of the driven shaft, penetrates through the mounting shell and is abutted to all the rollers. Further, the driven shaft comprises a boss portion, the diameter of the driving shaft is smaller than that of the boss portion, the boss portion is provided with a first transmission plane penetrating through the boss portion along the radial direction of the driving shaft, the driving shaft is embedded into the boss portion, and the driving shaft is provided with a second transmission plane abutting against the first transmission plane. Further, the driven shaft is centrally arranged in the mounting groove, and at least two rollers are circumferentially arranged on the periphery of the driven shaft. Further, the roller is characterized by further comprising a mounting seat, wherein the mounting seat is provided with a plurality of mounting shafts which are arranged at intervals, and a connecting plate which is connected with the mounting shafts, the mounting seat is embedded in the bottom of the mounting groove, and the roller is rotatably sleeved on the mounting shafts. Further, the mounting device also comprises an end cover, wherein the end cover is fixedly connected with the mounting shell, and the end cover seals the opening of the mounting groove. Further, a ball is arranged between the end cover and the driven shaft, and the upper end part of the ball is embedded into the end cover. Further, the roller is provided with a hollowed-out part. The peristaltic pump has the beneficial effects that the peristaltic pump comprises a mounting shell, a motor fixedly arranged on the mounting shell, a driving shaft arranged on the motor, a mounting groove formed on the mounting shell, a plurality of rollers arranged in the mounting groove, a hose arranged between the wall of the mounting groove and the rollers, and a driven shaft detachably connected with the driving shaft, wherein the driving shaft is embedded at the lower end of the driven shaft, the driven shaft penetrates through the mounting shell and is abutted to all the rollers, and the driving shaft is detachably selected from the driven shaft and the driving shaft and is embedded at the lower end of the driven shaft, so that lubricating oil in the motor can be prevented from flowing between the driven shaft and the rollers to idle the motor.
