The present invention relates to a tube pump, and more particularly, to a tube pump that presses a tube by wave motion to prevent the phenomenon of being pushed by the reaction force in the direction opposite to the direction in which the fluid is actuated To a tubular pump.

Generally, a swirl pump or a swash plate pump, which is capable of delivering a fluid having a high viscosity, is suitable not only for low-speed and high-viscosity fluid transfer, but also for obtaining a high heading. However, such a swash- The driving is not stabilized and the feeding efficiency is also poor.

Accordingly, a tube pump having a disadvantage of preventing the pulsation phenomenon and having a high transfer efficiency is used, and the tube pump has a technical configuration of transferring the fluid by continuously changing the volume inside the tube.

In other words, the prior art related to a conventional tube pump, in the manner of conveying the fluid by wave motion in the longitudinal direction of the shaft using a tube, is disclosed in Korean Registered Utility Model No. 20-0221537 (hereinafter referred to as "Prior Art Document 1" And Korean Patent Laid-Open No. 10-2001-0039807 (hereinafter referred to as "Prior Art Document 2").

The technical construction of the tube pump described in this prior art document includes a drive shaft having a plurality of eccentric cams mounted at regular intervals such that the position of the top dead center repeats the ascending and descending positions of the top dead center in the same direction as the direction of the fluid, And a cam insertion hole for inserting the eccentric cams is formed at a lower portion of the tube and a lower portion of the tube is inserted into the upper portion of the tube. And a plurality of actuating rods which are formed in a tube insertion vertical slot into which the outer surface is inserted and interlocked with the rotation of the eccentric cams so as to be repeatedly ascended and descended in sequence.

In addition, a tube chamber in which the fixed shaft and the tube are mounted and an operation chamber in which the drive shaft is mounted are connected to each other inside and below the housing.

In the middle and the periphery of the bracket, both ends of the fixing shaft and the tube inserted into the outer side of the fixing shaft are inserted into the opening hole. Respectively.

In addition, a fixing bracket having mounting holes formed on both sides of the operation chamber is fixed to the housing, and a driving shaft to which the plurality of eccentric cams are mounted is mounted in the mounting hole in the lateral direction through a bearing.

The brackets mounted on both sides of the tube chamber include a cap formed at the center thereof to fix both ends of the fixed shaft and a mounting ring formed integrally with the periphery of the cap through ribs to fix both ends of the tube .

Accordingly, when the tube pump operates the driving unit connected to the driving shaft mounted on the lower portion of the housing, the top dead center position of the plurality of eccentric cams is sequentially raised and lowered in accordance with the rotation of the driving shaft, The position of the elevator is also changed and the elevation is repeated.

As a result, the tube is bent around the fixed axis by repeatedly changing the position of the operating rod, so that the fluid is introduced from one side and then transferred to the other side. When the fluid is transported, a compression force of the tube is generated, so that a transfer pressure is generated in the fluid passing through the tube.

The tube pump 100 is provided with a plurality of eccentric cams 122 (see FIG. 1), which are positioned at different positions in an operation chamber 114 formed on an inner lower side of a housing 110, on which an upper surface of the cover 112 is openably mounted by a usual bolt, And a tube chamber 116 formed at an inner upper portion of the housing 110 in parallel with the driving shaft 120. The driving shaft 120 is mounted on the outer side surface of the driving shaft 120, A fixed shaft 130 having both ends fixed with the tube 132 and a cam insertion hole 142 inserted into the eccentric cap 122 are formed in the lower portion of the tube 132, A tube insertion vertical slot 144 inserted into the outer surface of the tube 132 is formed to interlock with the rotation of the eccentric cams 122 so as to sequentially move up and down and include a plurality of operation rods 140 .

SUMMARY OF THE INVENTION The present invention is intended to prevent a phenomenon in which a working rod for conveying a fluid is pushed by a reaction force in a direction opposite to a direction in which a fluid is operated when the working rod is lifted or lowered.

The technical structure as a solution means according to the present invention is a configuration in which the upper and lower working rods 140 and 142 are divided in the lateral direction with respect to the tube insertion vertical slot 144 of the operating rod 140 and both sides thereof are fastened and fixed by bolting, 140A and a lower operating rod 140B.

That is, in the process of inserting each tube insertion vertical slot of the plurality of operation rods while the tube is inserted into the outer side of the fixed shaft, the tube is pushed or overlapped due to friction and interference with the outer surface of the flexible tube In order to compensate for the troublesome assembling work as well as long assembling time, it is necessary to position the upper and lower operating rods to the position where the tube is to be mounted from the outer side of the tube, It is advantageous in that it is possible to remarkably shorten the assembly time as well as the convenience of assembly.

The upper and lower ends of the lower operation rod 140B are coupled with the housing 110 to move the operation rod 140 in the opposite direction to the direction in which the fluid is moved in the course of the fluid being moved up and down. 140) are prevented from being pushed by the support guide means (1).

In other words, the operation rod is moved up and down by a predetermined distance in the direction opposite to the direction in which the fluid is actuated by the reaction force in the process of pressing the tube so as to move the fluid while the upper part is lifted and lowered in the state where it is coupled to the outer surface of the tube, The phenomenon of moving occurs. Thereby resulting in a decrease in the efficiency of transfer of the fluid.

This problem can be solved by the support guide means of the present invention.

That is, by engaging the upper and both upper ends of the lower operating rod with the housing without causing any obstacle to the lifting, the supporting guide means prevents the operation rod from being pushed in the direction opposite to the direction in which the fluid is actuated by the reaction force due to the fluid transportation will be.

The support guide means 1, which is a specific technical construction for preventing the operation rod from being pushed by the reaction force in the direction opposite to the direction in which the fluid is operated as described above, is provided on both upper and side ends of the lower operation rod 140B, The lower end of the support flange 10 is inserted into the insertion groove 12 of the support flange 10 and the lower end of the support flange 10 is integrally formed with the support flange 10, And a guide rod 20 inserted into the groove 22 and inserted into the upper setting groove 24 formed at the upper end of the cover 120.

Accordingly, when the operating rod is lifted and lowered on the guide rod supported by the cover and the guide rod supported by the housing, the flow of the operation rod is prevented from being caused to flow to the left and right, and the guide rod fixed to the upper and lower three- Is pushed by the reaction force in the direction opposite to the direction in which it is actuated.

Thereby increasing the efficiency of transporting the fluid and ensuring high reliability.

In addition, the guide groove 20 is formed in the insertion groove 12 so that the guide rod 20 is inserted into the guide groove 20 so that the lifting and lowering of the operation rod 140 can be performed stably, Further comprising a support bushing (21).

And thereby the surface of the operating rod is brought into surface contact with the support bushing on the guide rod, so that the operating rod can be made more stable in the guide rod.

A slider 30 (not shown) is provided between both sides of the lower operating rod 140B and the inner side of the housing 110 to prevent the lower operating rod 140B from flowing to the left and right as the operating rod 140 moves up and down. ) Are further intervened. The slider is preferably provided to be coupled and fixed to the lower operating rod by a conventional method.

As a result, the lower operation rod can be prevented from flowing sideways by the slider in the process of ascending and descending, and the entire operation rod can be raised and lowered more stably, thereby further increasing the efficiency of transporting the fluid.

On the other hand, at both ends of the tube 132, a general flange-shaped airtight flange 40 having a diameter wider than the diameter of the tube 132 for sealing is integrally formed. The airtight flange 40 includes a fixing cap 43, a fixing washer 44, and a fixing bracket 42 together with a fixing bracket 42 provided at both ends of the housing 110 and each end cover 112 of the fixing shaft 130. [ And is fixed so as to have airtightness by the respective inflow ports or discharge ports 45 and the finishing cap 46. The fixed cap has a structure in which a fixing hole into which both ends of the fixing shaft are inserted at the center is formed with a plurality of through holes so as to allow the fluid transferred through the tube to pass around the fixing hole and closely contact with the airtight flange.

The fixing bracket 42 is divided into upper and lower portions to be engaged with both ends of the cover 112 and the housing 110. This is to make the assembly more simple and convenient.

Thereby allowing each end of the tube to be secured with a higher degree of airtightness so that the fluid delivered through the tube does not leak through each end of the tube.

In order to solve the problem of wear and breakage due to the fatigue generated on both sides of the tube 132 by the amount of eccentricity between the operating rod 140 located at both ends of the fixed shaft 130 and both ends of the fixed shaft 130, The eccentric cam 122 mounted on the driving shaft 120 is formed such that the amount of eccentricity gradually decreases from the middle to the both ends of the driving shaft 120. [

In other words, by reducing the amount of eccentricity from the middle of the drive shaft to both ends of the drive shaft, the amount of eccentricity between the end of the drive shaft and both ends of the drive rod is reduced, It also has conditions that can prevent fracture due to abrasion. Thereby allowing the tube to be used for a longer period of time.

5 is a partial perspective view for explaining another second embodiment of the present invention.

As shown in the drawings, the support guide means 1, which is a specific technical construction for preventing the phenomenon that the operation rod lifted and lowered for transporting the fluid is pushed by the reaction force in the direction opposite to the direction in which the fluid is operated, So that it can be simply provided.

The support guide means 1 includes guide projections 10A formed on both upper and lower sides of the lower operation rod 140B and guide grooves 10A formed on the inner surface of the housing 110 at positions corresponding to the guide projections 10A 20A.

Thereby preventing the operation rod from being pushed by the reaction force in the opposite direction to the direction in which the fluid is operated without causing any trouble to the lifting and lowering of the operating rod due to the fluid transportation, The efficiency of transporting the fluid can be increased.

6 is a partial perspective view and a cross-sectional view for explaining another third embodiment of the present invention.

As shown in the drawings, in the above-described construction, in the process of transferring the fluid while sequentially pushing the tube along the lifting and lowering of the operation rod, the tube and the fixed shaft are brought into point contact, that is, There is a phenomenon that some of fluids can not be smoothly transferred during the point contact of the tube to the fixed shaft due to the pressurization of the operation rod.

The fixed shaft 130 and the tube 132 further include respective sliding contact surfaces 50 where both side surfaces abut against each other. At this time, it is preferable that a tube insertion vertical slot of the operation rod fastened to the outer side surface of the tube is also formed in a shape corresponding to each sliding movement surface.

Since the both sides of the tube are in surface contact with each other by the sliding surfaces of the tube and the fixed shaft when the tube is pressed by the lifting and lowering of the operating rod, the fluid is not transferred through the sliding surfaces, So that the transfer efficiency of the fluid can be maximized.

7 is an exploded perspective view for explaining another fourth embodiment of the present invention.

As shown in the drawings, in the case where there is a hard foreign matter having a small volume included in the fluid in the course of the fluid being transported through the tube being pressurized by the actuating rod lifted on the fixed shaft, The long hole does not pass through the tube when it is pressurized. Accordingly, a technical structure is proposed in order to smoothly transfer the foreign substance even if the foreign matter having such a small volume is contained in the fluid.

A flexible cushion packing 60 such as a conventional rubber or silicone formed to partition the outer surface of the tube between the tube insertion vertical slot 144 of the operation rod 140 and the tube.

Even when there is a foreign matter having a small volume contained in the fluid in the process of pressing the tube on the inner side of the tube insertion vertical slot while the operation rod is lifted and lowered by the cushioning force of the cushion packing, A hard foreign substance having a small volume can be smoothly transferred.

8 is a side view for explaining another fifth embodiment of the present invention.

As shown in the drawings, in the above-described structure, a structure in which the left and right rotation can be smoothly performed according to the eccentric amount of the eccentric cam while reducing the volume of the lower operation rod.

The lower operation rod 140B further includes an auxiliary operation rod 140B-1 formed by dividing a portion where the cam insertion hole 142 is formed, and the upper end of the auxiliary operation rod 140B- And is rotatably provided by pin engagement with the lower portion of the lower case 140B. At this time, the cam insertion hole is formed in a circular shape corresponding to the eccentric cam.

And the cam insertion hole is formed in a rectangular shape horizontally in order to compensate for the lateral movement due to the rotation of the eccentric cam, the volume of the cam insertion hole must be increased. When the eccentric cam is rotated at its starting point, the eccentric cam is rotated right and left by the amount of eccentricity so that the overall volume of the lower operating rod is remarkably reduced and the amount of eccentricity is compensated.
