Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pump tubes, in particular to a micro self-maintaining peristaltic pump tube. Background Art

[0002] The peristaltic pump tube, namely the peristaltic pump hose, is one of the components of the peristaltic pump, and it plays a crucial role in the operation of the peristaltic pump; the peristaltic pump tube is one of the key components of the peristaltic pump and also its important working component. It is a flexible pipe, one end is connected to the pump head, and the other end is connected to the container or pipe for transporting the medium. A series of pump cavities are arranged on the inner wall of the peristaltic pump tube. When the pump head works, the pump cavities will contract and peristalsis in turn, so as to realize the transportation of liquid.

[0003] The structure of the peristaltic pump tube is relatively simple, usually made of high-strength rubber material. As a whole, it presents a flexible pipe. A series of pump cavities are arranged on the inner wall of the pipe, and the pump cavities are separated by films. This structure enables the pump cavities to contract and peristalsis in turn under the action of the pump head.

[0004] The conventional peristaltic pump tube will have problems of deformation and failure due to long-term static extrusion, resulting in a large impact on the elastic contraction and sealing performance of the mechanism when transporting fluids, and thus frequent manual maintenance is required, bringing various inconveniences, affecting the operation efficiency and increasing the maintenance cost.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a micro self-maintaining peristaltic pump tube is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to provide a micro self-maintaining peristaltic pump tube to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a micro self-maintaining peristaltic pump tube, including a main pipe body and an inner pipe body. An outer pipe body is sleeved on the outer surface of the main pipe body, and a protective strip is arranged between the outer pipe body and the main pipe body. Moreover, lubricating grease is filled at the joints between the main pipe body, the outer pipe body and the protective strip. And an inner lining sleeve is attached to the inner wall of the main pipe body, and the inner pipe body is attached to the inner wall surface of the inner lining sleeve.

[0008] Further, the main pipe body includes an elastic layer, an anti-static layer and a crack-proof layer. The anti-static layer is glued to the upper and lower surfaces of the elastic layer, and the crack-proof layer is attached to the surface of the anti-static layer away from the elastic layer.

[0009] Further, the outer pipe body includes an outer pipe sleeve, a limiting groove and a reinforcing rib. The limiting groove is opened on the inner wall of the outer pipe sleeve, and the reinforcing ribs are arranged between the limiting grooves.

[0010] Furthermore, both the limiting groove and the reinforcing rib are arranged in a circular array with the outer pipe sleeve as the center, and the outer pipe sleeve and the reinforcing rib are integrally structured.

[0011] Furthermore, the protective strip includes a soft rubber strip, an anti-static coating, and a wear-resistant coating. The anti-static coating is sprayed on one side surface of the soft rubber strip close to the outer pipe body, and the wear-resistant coating is sprayed on one side surface of the soft rubber strip close to the main pipe body.

[0012] Furthermore, the surface structure of the soft rubber strip matches the surface structure of the limiting groove, and the soft rubber strip is arranged in a circular array with the outer pipe sleeve as the center.

[0013] Furthermore, the inner pipe body is tightly glued between the main pipe body and the inner pipe body, and the grease is used for structural sealing and lubrication protection between the main pipe body, the outer pipe body, and the protective strip.

[0014] Furthermore, the inner pipe body has the same structure as the main pipe body, and the inner wall surface of the inner pipe body is provided with a spiral corrugated structure.

[0015] The utility model provides a micro self-maintaining peristaltic pump tube, which has the following beneficial effects:

[0016] 1. In the utility model, by setting the inner wall of the inner pipe body as a spiral corrugated structure, and at the same time using the same material structure for the inner pipe body and the main pipe body, and cooperating with the use of the inner lining sleeve, good stage structure sealing can be achieved under the extrusion of the ball-type pump core. On the one hand, it can avoid structural pressure relief during the process of pushing the fluid for transportation under pressure, resulting in inaccurate transmission of the transported medium, so as to maximize the consistency and stability of the fluid transmission effect. On the other hand, this structure can also provide a certain degree of structural support and anti-extrusion performance to a certain extent, so that the entire peristaltic pump tube can have good self-maintenance performance. In addition, when the pump core extrudes the entire peristaltic pump tube, charges will inevitably be generated due to friction. By using the anti-static coating on one side surface of the soft rubber strip and the anti-static layers on both sides of the elastic layer, the generation of charges can be alleviated as much as possible, so that when the entire peristaltic pump tube faces medical equipment sensitive to electrical noise, unnecessary influence and interference can be minimized.

[0017] 2. The utility model uses the structure of the outer tube body and the protection strip, wherein a plurality of limiting grooves are formed in an annular array on the inner wall surface of the outer tube sleeve, and reinforcing ribs are provided between each limiting groove. By using the above structure, the outer tube body and the outer tube body itself can be effectively protected from structural extrusion, and can have good structural compressibility and support. At the same time, since the structure on one side of the soft rubber strip itself matches the limiting groove, the entire protection strip can be formed in an annular array and horizontally embedded in the limiting groove. Moreover, since the soft rubber strip is made of a memory shape rubber material, its structural characteristics can be used to provide effective structural support for the outer tube body on the one hand. At the same time, with the structural setting of the reinforcing ribs, the problem of deformation failure of the main tube body itself due to reciprocating extrusion can be minimized, playing a role similar to that of a skeleton support. On the other hand, it can also provide good structural protection for the peripheral main tube body. With the structural setting of the outer tube body, even when the main tube body itself is broken, structural protection can be performed at the first time to avoid leakage of the internal fluid.

[0018] 3. The utility model fills grease between the main tube, the outer tube and the protective strip, which can, on the one hand, serve as a filler and seal between the three structural parts, and can also absorb and alleviate the structural elastic potential energy to a certain extent. On the other hand, the grease can also reduce the mutual friction between the main tube, the outer tube and the protective strip as much as possible, thereby reducing the generation of electric charge, and can also play a lubricating role. When the temperature of the entire peristaltic pump tube is increased by the friction force generated by high-speed repeated extrusion, the grease can also assist in providing partial heat conduction and dissipation for the entire peristaltic pump tube as much as possible, thereby ensuring the overall service life of the peristaltic pump tube as much as possible.

DETAILED DESCRIPTION

[0023] The embodiments of the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0024] As Figures 1 to 3 shown, a micro self-maintaining peristaltic pump tube includes a main pipe body 1 and an inner pipe body 6. An outer pipe body 2 is sleeved on the outer surface of the main pipe body 1, and a protective strip 3 is provided between the outer pipe body 2 and the main pipe body 1. Moreover, a grease 4 is filled at the joint between the main pipe body 1, the outer pipe body 2 and the protective strip 3. And a lining sleeve 5 is attached to the inner wall of the main pipe body 1. The inner pipe body 6 is attached to the inner wall surface of the lining sleeve 5. The inner pipe body 6 is tightly glued between the main pipe body 1 and the inner pipe body 6. And the grease 4 is used for structural sealing and lubrication protection between the main pipe body 1, the outer pipe body 2 and the protective strip 3. The inner pipe body 6 has the same structure as the main pipe body 1, and the inner wall surface of the inner pipe body 6 is provided with a spiral corrugated structure. By setting the inner wall of the inner pipe body 6 as a spiral corrugated structure, and at the same time the inner pipe body 6 and the main pipe body 1 adopt the same material structure, and in cooperation with the use of the lining sleeve 5, it can have good stage-structural sealing under the extrusion of the ball-type pump core. In addition, by using the antistatic coating 302 on one side surface of the soft rubber strip 301 and the antistatic layers 102 on both sides of the elastic layer 101, the generation of charges can be alleviated as much as possible, so that when the entire peristaltic pump tube faces medical equipment sensitive to electrical noise, unnecessary influences and interferences can be reduced as much as possible.

[0025] As Figures 1 to 3As shown, the main body 1 includes an elastic layer 101, an antistatic layer 102 and an anti-cracking layer 103. The antistatic layer 102 is glued to the upper and lower surfaces of the elastic layer 101, and the anti-cracking layer 103 is adhered to the surface of the antistatic layer 102 away from the elastic layer 101. The outer tube body 2 includes an outer tube sleeve 201, a limiting groove 202 and a reinforcing rib 203. The inner wall of the outer tube sleeve 201 is provided with a limiting groove 202, and the limiting grooves 202 are provided with reinforcing ribs 203. The limiting grooves 202 and the reinforcing ribs 203 are arranged in an annular array with the outer tube sleeve 201 as the center, and the outer tube sleeve 201 and the reinforcing rib 203 are arranged as an integrated structure. The protective strip 3 includes a soft rubber strip 301, an antistatic coating 302 and a wear-resistant coating 303. The surface of the soft rubber strip 301 on one side close to the outer tube body 2 is sprayed with an anti-static coating 302, and the surface of the soft rubber strip 301 on one side close to the main tube body 1 is sprayed with a wear-resistant coating 303. The surface structure of the soft rubber strip 301 matches the surface structure of the limiting groove 202, and the soft rubber strip 301 is arranged in a circular array with the outer tube sleeve 201 as the center. Through the use of the structure of the outer tube body 2 and the protective strip 3, a number of limiting grooves 202 are opened in a circular array on the inner wall surface of the outer tube sleeve 201, and reinforcing ribs 203 are arranged between each limiting groove 202. By using the above structure, the outer tube body 2 and the outer tube body 2 itself can be effectively protected from structural extrusion, and can have good structural compressibility and support.

[0026] In summary, if Figures 1 to 3 As shown, when the micro self-maintaining peristaltic pump tube is used, first, when the entire peristaltic pump tube is squeezed by the pump core, the outer tube body 2 and the protection strip 3 are simultaneously squeezed by the structure. In this process, the outer tube sleeve 201 uses the reinforcing ribs 203 on the inner wall surface to cooperate with the soft rubber strip 301 embedded in the limiting groove 202, which can play a protective role of structural support and reset without affecting the structural deformation;

[0027] After the outer tube body 2 and the protection strip 3 are squeezed, the inner liner 5, the main tube body 1 and the inner tube body 6 are squeezed in turn to produce deformation. Due to the spiral corrugated structure adopted on the inner wall surface of the inner tube body 6, the stability of fluid transportation is ensured to the greatest extent.

[0028] During the entire extrusion reciprocating process, the antistatic coating 302 on one side of the soft rubber strip 301 and the antistatic layers 102 on both sides of the elastic layer 101 are used to avoid the generation of charges due to structural extrusion friction as much as possible, thereby avoiding unnecessary influence. At the same time, the grease 4 filled between the main tube 1, the outer tube 2 and the protective strip 3 can provide lubrication protection and reduce structural friction, and at the same time, it can also help to provide partial heat conduction and dissipation for the entire peristaltic pump tube as much as possible, thereby ensuring the overall service life of the peristaltic pump tube as much as possible.
