Technical Field
[0001] The utility model relates to the technical field of peristaltic pumps, in particular to a novel overload-proof peristaltic pump. Background Art
[0002] Peristaltic pumps consist of three parts: drive, pump head and hose. The main competitive advantages of peristaltic pumps are that the fluid is isolated in the pump tube, the pump tube can be quickly replaced, the fluid is reversible, dry operation is possible, and maintenance costs are low.
[0003] When using an existing peristaltic pump, if it is conveying a liquid with a high density, a large power output is required to squeeze the peristaltic pump hose. However, the rapid operation of the motor can easily cause damage under long-term operation under high load. For this reason, we propose a new type of peristaltic pump that is overload-proof. Utility Model Content
[0004] In view of the above problems, the utility model provides a novel overload-proof peristaltic pump, which has the function of preventing overload from occurring and causing damage to the motor.

[0006] A novel peristaltic pump with overload protection comprises a motor, a reduction gear lower shell is installed at one end of the motor, a driving tooth is installed on the output shaft of the motor, driven teeth are meshed and connected on both sides of the driving tooth, an output gear ring is meshed and connected at one end of the driven tooth, a bracket is installed on one side of the output gear ring, an output shaft is installed on the other side of the output gear ring, a cross pin is fixedly installed on one end of the output shaft close to the output gear ring, a tripod is installed on the other end of the output shaft, pins are installed at three corners of the tripod, rollers are sleeved on the surface of the pins through shaft sleeves, an upper cover is movably installed on the tripod through a bearing, a base is installed on one side of the upper cover, a hose is installed on the periphery of the tripod, a reduction gear upper shell is installed on one side of the base, and the reduction gear upper shell is installed on the outside of the output gear ring.
[0007] In a further technical solution, three threaded grooves are installed on one side of the base, and three hand screws are installed on one side of the upper cover. The hand screws pass through the upper cover and are installed in the threaded grooves.
[0008] In a further technical solution, pipe joints are installed at both ends of the hose.
[0009] In a further technical solution, a transverse groove is provided on one side of the tripod, and the transverse pin is installed in the transverse groove.
[0010] In a further technical solution, the driven tooth is composed of two gears, the diameter of the gear on the top end of the driven tooth is smaller than the diameter of the gear on the bottom end of the driven tooth, and a gear block is provided on the inner wall of the output gear ring.
[0011] The beneficial effects of the utility model are:
[0012] The device drives the active gear to rotate through a motor, and the active gear drives the driven gear to rotate, and the driven gear drives the output gear ring to rotate, so that the output gear ring drives the tripod to rotate through the output shaft, and the roller can be used to squeeze the liquid in the hose, so that the liquid is transported from one end of the hose to the other end. The active gear drives the driven gear to rotate, and the driven gear only rotates one circle after the active gear rotates multiple circles. When the density of the transported liquid is high, the load of the motor can be reduced. At the same time, the driven gear drives the output gear ring to rotate, which can dissipate part of the stress, thereby increasing the service life of the device and reducing the failure rate.

[0016] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0017] Example:
[0018] like Figure 1As shown, a new type of peristaltic pump with overload protection includes a motor 1, a reduction box lower shell 2 is installed at one end of the motor 1, a driving tooth 3 is installed on the output shaft of the motor 1, and driven teeth 4 are meshed and connected on both sides of the driving tooth 3, and an output ring gear 6 is meshed and connected at one end of the driven tooth 4. A bracket 5 is installed on one side of the output ring gear 6, and an output shaft 7 is installed on the other side of the output ring gear 6. A cross pin 8 is fixedly installed on the end of the output shaft 7 close to the output ring gear 6, and a tripod is installed on the other end of the output shaft 7. Pins 11 are installed at the three corners of the tripod. The surface of the pin 11 is sleeved with a roller 12 through a shaft sleeve 14, and the tripod is movably installed with an upper A cover 15 is provided, a base 10 is installed on one side of the upper cover 15, a hose 17 is installed on the periphery of the tripod, a reduction gear upper shell 9 is installed on one side of the base 10, the reduction gear upper shell 9 is installed on the outside of the output gear ring 6, three threaded grooves are installed on one side of the base 10, three hand screws 16 are installed on one side of the upper cover 15, the hand screws 16 penetrate the upper cover 15 and are installed in the threaded grooves, pipe joints 18 are installed on both ends of the hose 17, a transverse groove is provided on one side of the tripod, a transverse pin 8 is installed in the transverse groove, the driven gear 4 is composed of two gears, the gear diameter on the top end of the driven gear 4 is smaller than the gear diameter on the bottom end of the driven gear 4, and a gear block is provided on the inner wall of the output gear ring 6.
[0019] The working principle of the above technical solution is as follows:
[0020] When the device is running, the motor 1 is started, the motor 1 drives the active gear 3 to rotate, the active gear 3 drives the driven gear 4 to rotate, so that the gear at the top of the driven gear 4 drives the output ring gear 6 to rotate, the output ring gear 6 drives the output shaft 7 and the cross pin 8 to rotate, because the cross pin 8 is stuck in the transverse groove on the tripod, thereby driving the tripod to rotate, and the three rollers 12 on the tripod squeeze the liquid in the hose 17, so that the liquid in the hose 17 is transported from one end to the other end. When the device needs to be disassembled, the upper cover 15 can be disassembled by screwing the three hand screws 16.
