Description

Technical Field

[0001] The invention relates to the technical field of peristaltic pumps, in particular to a peristaltic pump and a vibration-damping bracket thereof. Background Art

[0002] Peristaltic pump is a common liquid pump. When in use, the roller group on the pump head is driven to continuously squeeze the pipeline, thereby promoting the flow of liquid in the pipeline. It has the characteristics of high precision, low shear force, good sealing and convenience, so it is often used in medical, chemical, biological and other fields.

[0003] During actual use, the pump core of the peristaltic pump is in a high-speed rotation state. At the same time, the pump core is also subjected to reaction force in the process of constantly squeezing the pipeline, which will cause the pump core to vibrate to a certain extent. On the one hand, the noise during operation is very loud. On the other hand, long-term vibration will also cause the components to loosen directly, further affecting the stability of the peristaltic pump. Summary of the invention

[0004] In view of the above problems, the object of the present invention is to provide a peristaltic pump and a vibration-damping bracket thereof, which can effectively reduce the vibration generated during the operation of the peristaltic pump, reduce noise and ensure stable operation of the peristaltic pump.

[0005] In order to solve the above technical problems, the first technical solution adopted by the present invention is as follows: a peristaltic pump vibration damping bracket, comprising a main bracket, a sub-bracket hinged on the main bracket, a vibration damping device is provided in the middle of the sub-bracket, the vibration damping device comprises connecting bolts, a vibration damping ring and a vibration damping cover ring, the connecting bolts pass through the vibration damping cover ring and the sub-bracket and are fixed on the main bracket, the vibration damping ring is sleeved on the connecting bolts, the vibration damping cover ring is covered on the vibration damping ring, the main bracket is provided with a spring cavity, a vibration damping spring is provided in the spring cavity, and the vibration damping spring is against the sub-bracket.

[0006] In the above technical solution, one side of the spring cavity is a flared section, and the flared section is trumpet-shaped, and the diameter gradually increases from the inside to the outside.

[0007] In the above technical solution, the main bracket is hinged on the sub-bracket which is hinged with two sub-brackets, one end of the sub-bracket is connected to the main bracket through a hinge shaft, and the connecting bolt is installed in the middle of the sub-bracket.

[0008] In the above technical solution, the two auxiliary supports are symmetrically arranged along the main rotation axis in the middle of the main support.

[0009] In the above technical solution, a bolt sleeve is provided on the main support, the connecting bolt is inserted into the bolt sleeve, and the vibration-damping cover ring is sleeved on the outer circumference of the bolt sleeve.

[0010] In the above technical solution, the bracket is provided with an outer cover, the outer cover is provided with a handle, the handle is hinged to the outer cover and can be embedded in an embedding groove on the outer cover.

[0011] In the above technical solution, a teardrop-shaped gripping portion is provided at the end of the handle, and the gripping portion gradually widens from the inside to the outside.

[0012] In the above technical solution, a fixing buckle is provided in the middle of the embedding groove, and the middle of the handle can be clamped in the fixing buckle.

[0013] In order to achieve the above object, the second technical solution of the present invention is: a peristaltic pump, comprising a housing, wherein the above-mentioned vibration-damping bracket is arranged in the housing, and a roller is arranged on a sub-bracket of the vibration-damping bracket.

[0014] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the sub-bracket of the peristaltic pump core in the present invention is hinged on both sides of the main bracket, and a vibration damping device is arranged between the main bracket and the sub-bracket, and a vibration damping spring is arranged on the main bracket. While the vibration damping device connects the main bracket and the sub-bracket through connecting bolts, it absorbs vibration through the shock-absorbing ring, and the vibration damping spring can effectively absorb the reaction force generated when the sub-bracket squeezes the pipeline during operation. The combination of the two greatly reduces the vibration generated during the operation of the peristaltic pump, reduces the noise emitted from the pump core, and ensures the stable operation of the peristaltic pump.

DETAILED DESCRIPTION

[0026] The following is an ideal embodiment of the present invention. Through the following description, relevant staff can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.

[0027] The present invention will be further described with reference to the following drawings:

[0029] like Figure 7 As shown, one side of the spring cavity 111 is a flared section, which is trumpet-shaped, and the diameter gradually increases from the inside to the outside. The flared section of the spring cavity 111 is in the shape of a trumpet mouth, and the shock-absorbing spring 112 is fixed at the bottom, and the mouth is away from the shock-absorbing spring 112, which can effectively reduce the impact sound emitted by the shock-absorbing spring 112 during use.

[0030] The main bracket 110 is hinged on the sub-bracket 120 , and two sub-brackets 120 are hinged on the sub-bracket 120 . One end of the sub-bracket 120 is connected to the main bracket 110 through a hinge shaft, and the connecting bolt 131 is installed in the middle of the sub-bracket 120 .

[0031] like Figure 4 , 7 As shown, the two auxiliary brackets 120 are symmetrically arranged along the main rotating shaft 113 in the middle of the main bracket 110, and the two spring chambers 111 are symmetrically arranged along the main rotating shaft 113 in the middle of the main bracket 110. The central symmetry can ensure that the center of gravity of the pump core is stable when rotating, and the operation is more stable.

[0032] like Figure 7 As shown, the main bracket 110 is provided with a bolt sleeve 114, the connecting bolt 131 is inserted into the bolt sleeve 114, and the vibration-damping cover ring 133 is sleeved on the outer periphery of the bolt sleeve 114.
