Description

{Operating rod for tube pump}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an operation rod applied to a tube pump, and more particularly, to an operation rod used for a tube pump capable of transferring a fluid by a left and right swinging method, Lt; / RTI >

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 operation principle of the tube pump is such that the fluid is transported by the wave motion accompanying the lifting and lowering in the longitudinal direction of the shaft by using a tube.

The prior art of the tube pump to which the above-mentioned operating principle is applied includes the Korean Registered Utility Model No. 20-0174564 (hereinafter referred to as "Prior Art Document 1"), the Korean Registered Utility Model No. 20-0221537 (Hereinafter referred to as "Prior Art Document 3") and Korean Patent Application Publication No. 10-2001-0039807 (hereinafter referred to as "Prior Art Document 4"), the Korean Registered Utility Model No. 20-0401775 ).

The technical features of the tupp pump disclosed in the above-mentioned prior art documents 1 to 4 include a drive shaft having a plurality of eccentric cams mounted at regular intervals such that the position of the top dead center repeats ascending and descending in the same manner as the traveling direction of the fluid, A flexible tube having a diameter relatively larger than the diameter of the fixed shaft and being inserted into the outer surface of the fixed shaft and a cam insertion hole into which the eccentric cams are inserted are formed at a lower portion thereof And a plurality of actuating rods formed in the upper portion of the tube to insert a tube insertion vertical slot into which the outer surface of the tube is inserted and which is interlocked with the rotation of the eccentric cams and repeats ascending and descending sequentially.

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.

On the other hand, on the upper side of the tube chamber, a cover which can be opened for easy maintenance is mounted, a connection bracket for preventing the bracket from being separated from the bracket and connected to the fluid tube is mounted outside the opening hole, In the middle thereof, an expanded tube-tight portion is formed, and both sides of the tube-tight portion are formed with inclined portions so as to smoothly flow the fluid.

The brackets mounted on both sides of the tube chamber include a cap formed at the center and having both ends fixed to the fixing shaft, and a mounting ring formed integrally with the periphery of the cap through the 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 like a wave motion 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.

Korean Utility Model Registration No. 20-0174564 Korean Utility Model Registration No. 20-0221537 Korean Utility Model Registration No. 20-0401775 Korean Patent Publication No. 10-2001-0039807

However, the operation rod provided in the tube pump of the prior art documents 1 to 4 has a structure in which the waving motion can be performed according to the lift-up, that is, the drive shaft to which a plurality of eccentric cams are mounted at the bottom, Since the structure is such that the fluid is transported to the wave motion due to the ascent and descent while being inserted into and supported by the outer side surface, the fluid can not be transported while being rocked to the left and right.

Further, the assembling work for inserting the upper portion of the operating rod into the upper portion of the operating rod with the tube-covered fixed shaft on the outer side is considerably cumbersome and inconvenient.

In addition, there is a problem that the operation rod is lifted and lowered, the phenomenon of being pushed by the reaction force in the opposite direction of conveying the fluid, and the fluid can not be smoothly transferred due to the flow noise or the like.

In addition, the driving shaft is worn out in a short time due to the driving shaft and the wide friction surface due to the lifting and lowering operation rod.

In order to solve the above problems, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a tube pump capable of transferring a fluid by a right and left swinging method, Operating load.

The upper part of the main body is formed to have a structure to be closed with respect to the transverse direction of the tube insertion slot. The upper part is provided with a fixed clamp which is rotatably fixed at one end thereof and is rotatable, And a fixed wire fixed to the fixed body by covering the upper surface of the upper body and fixed by the fixed clamp.

In the tube insertion slot, a packing corresponding to the tube insertion slot is coupled and fixed.

The packing includes an integral type or a vertically divided type.

The cam insertion hole further includes protruded support protrusions on both sides of the inner side of the cam insertion hole for supporting both sides of the bearing coupled to the eccentric cam.

And each of the ball receiving grooves capable of receiving a respective ball is further formed on both sides of the upper surface of the front surface and the rear surface of the main body.

The present invention can maximize the efficiency of transporting fluids with minimum load as well as minimal power by allowing the operating rod for transporting the fluid to transport the fluid by the left and right swinging method instead of the waving motion accompanying the lifting and lowering .

In addition, since the installation of the fixed shaft covered with the tube can be made simple and convenient, the assembling work can be quickly performed in a short time, and also the maintenance can be made simple.

In addition, since friction with the tube can be minimized, damage to the tube can be prevented, thereby ensuring a long service life and further increasing the transport efficiency.

Fig. 1 is a perspective view for explaining the present invention, and Fig. 2 is an exploded perspective view in which the present invention is applied to a tube pump.

As shown in the figure, the tube pump 100 is used to feed fluids by continuously varying the volume inside the tube so as to have a high transport efficiency while preventing pulsation and being suitable for low-speed, high-viscosity fluid transportation.

The plurality of working rods 1 provided in the tube pump 100 are operated to directly transfer the fluid, that is, the plurality of eccentric cams are mounted, And flexes to transport the fluid.

The present invention provides an operation rod (1) for a tube pump in which a working rod for transferring a fluid is capable of transferring a fluid by a right and left swinging method instead of a wave-like motion accompanying ascent and descent.

The operating rod (1) according to the present invention comprises: a plate-shaped main body (10) having a predetermined thickness and width; A mounting hole 12 which is inserted and fixed to a lower portion of the main body 10 by a support shaft 112 fixed to an inner lower portion of a main body housing 110 of a tube pump 100 which is a fixed end;

A plurality of eccentric cams 114A mounted on the inner surface of the main body housing 110 of the tube pump 100 at regular intervals by a driving shaft 114 rotated by the power means are provided on the mounting hole 12, A cam insertion hole (14) inserted with the bearing (114B) of the cam follower; And a tube insertion slot (not shown) which is inserted into the outer surface of the tube 117, which is covered on the upper side of the cam insertion hole 14 with flexibility on the outer surface of the fixing shaft 116 so that the fluid can be transferred by a conventional method, 16) are provided.

The tube insertion slot 16 is preferably formed in an elliptical shape that corresponds to a range in which the eccentric cam is rotated for smooth rocking motion of the upper portion of the actuating rod by the eccentric cam. Accordingly, when the operating rod is pivotally moved from side to side, contact with the tube is smoothly performed, so that fluid can be smoothly transferred.

The operation rod of the present invention configured as described above includes a plurality of eccentric cams mounted on a drive shaft rotated by a power means, And the upper portion formed with the tube insertion slot inserted therein is pivoted from side to side.

So that the fluid in the tube bends the left and right sides of the tube about the fixed axis while the upper tube insertion slot of the operating rod inserted into the outer side of the tube is pivotally moved by the operating rod swinging to the left and right, To the opposite side.

Accordingly, compared to the conventional operation rod, the load is not generated much compared with the case of raising and lowering the entire operation rod, that is, the mounting hole formed in the lower part of the operation rod of the present invention is inserted and fixed on the support shaft, Can be minimized.

Further, the left and right swinging motion of the operating rod is also swung to the left and right only by the eccentric amount of the eccentric cam by the rotation of the drive shaft with minimum power, that is, with the lower portion being supported and fixed by the mounting hole in the fixed- , It is possible to smoothly oscillate left and right even with a minimum power.

Therefore, it is possible to uniformly pump the fluid conveyance in the tube constantly, thereby providing a condition for maximizing the conveying efficiency.

As a result, the operation rod provided in the tube pump of the present invention is pivotally moved by a simple principle to transfer the fluid, thereby maximizing the transfer efficiency of the fluid and smoothly driving the pump with minimal power and load. So that high reliability can be ensured.

It is preferable that each of the ball receiving grooves 18 in which the balls B can be received is further formed on both sides of the front and rear of the main body 10.

That is, the ball is received by the ball receiving grooves between the operating rods in the operation of the operating rod and has a condition capable of minimizing the frictional loss between the operating rods by the interposed balls. Particularly, the phenomenon in which the fluid is pushed by the reaction force in the opposite direction to be conveyed can also be minimized due to the reduction of the friction loss, and also the condition that the flow noise with the water can be minimized.

FIG. 3 is a partially exploded perspective view for explaining another embodiment of the present invention, and FIG. 4 is a flowchart for explaining a closed state of the open portion according to FIG.

As shown in the drawings, in the above-described configuration, a tube having a long insertion length of the operation rod is provided with a technical structure capable of more easily and conveniently mounting the tube covered with flexibility on the outer surface of the fixed shaft.

The upper part of the main body 10 is formed to have a structure to be opened and closed with reference to the transverse direction of the tube insertion slot 16. A fixed clamp 20 And one end of which is rotatably fixed to the opposite side of the fixing clamp 20 by a conventional pin or the like so as to cover the upper surface of the upper body 10A, (30) fixed to the base (20). The fixed wire may be any known technical arrangement capable of fixing or opening the closed upper body in addition to the above-described structure as part of a conventional locking means that allows the upper body to be opened or closed together with the clamping clamp Also,

Accordingly, the tube, which is covered with the tube insertion slot to have flexibility on the outer side of the fixing shaft, is opened by fixing the upper body to the tube insertion slot and then closing the upper body again to fix the convenience of easy installation without inconvenience or inconvenience to provide. In addition, since the upper body is opened and closed, the maintenance of the tube or the fixed shaft can be carried out quickly and quickly without any inconvenience.

In addition, a packing 40 corresponding to the tube insertion slot 16 is fixedly coupled to the tube insertion slot 16. The coupling of the packings is made by conventional grooves and projections of a corresponding type.

Thereby flexibly flexing the tubes to the left and right sides of the tube about the fixed axis by means of the packing, thereby preventing the tube from being damaged and further increasing the fluid transfer efficiency.

And the packing 40 includes an integral or vertically divided shape corresponding to the tube insertion slot. That is, when the packing is formed as an integral type, the tube should be inserted from one side, but it may be formed in a vertically divided form so as to be combined with the tube insertion slot of the upper body and the tube insertion slot formed in the lower body thereof, It is convenient to use.

On the other hand, protruding support protrusions 14A are provided on both sides of the inner side of the cam insertion hole 14 to support both sides of the bearing 114B coupled to the eccentric cam 114A. That is, the bearing is coupled to the outer side surface of the eccentric cam. When the bearing is inserted and fixed by the cam insertion hole, the entire outer ring of the bearing is not fixed but the outer ring is fixed by the respective support protrusions. .

Therefore, the mounting to the cam insertion hole is also more convenient, simple, and easy.

Particularly, since the bearing supporting the eccentric cam is supported by the support protrusion, the cam insert hole must be machined according to the driving motion of the eccentric cam, thereby preventing economic loss and long processing time It has a condition that can solve the problem that is required.
