Pipe fixing structure of air conditioning machine

The present invention provides a pipe body fixing structure of an air conditioning machine, and particularly relates to a structure applied to an air conditioner device for fixing a pipe body structure.

Nowadays, air-conditioning devices (cooling towers and evaporative coolers) are mostly exchanged by fluid transfer. Therefore, the pipeline devices in the air-conditioning device are numerous and complicated, and how the pipeline is fixed and does not leak water is the design focus of the air-conditioning device.

Referring to FIG. 1, taking the cooling water tower 8 as an example, the machine wall 82 is provided with an inlet pipe joint 821 and a water outlet port 822 for connecting the relevant pipelines. Some of the connections are made by soldering the metal tube. Alternatively, there is a flange interface formed at the interface to form a flange (or flange). Correspondingly, the external pipeline also needs to be connected to a flange adapter, and the flange adapter also has a flange. A flange pad is added between the two flanges, and two flanges are fixed by a plurality of bolts to complete the connection. The above connection methods are quite time consuming and take up considerable space.

Another common way of connecting the pipeline to the cooling tower is as shown in Fig. 2. First, a hole 820 is drilled in the wall 82 of the machine to install a pair of forced water joints 84, 86. A leak proof gasket 85 is also required between the forced water pipe joints 84, 86. In addition, an adapter joint 87 is screwed to the outer forced water pipe joint 86, and the adapter joint 87 can be connected to the pipeline to be connected to the pump. The inner forced hose joint 84 can be connected to a screen 88 or to another line. This type of pipeline connection method has a large number of components Increase costs and labor hours. Furthermore, the arrangement of the forced water pipe joints 84, 86 and the adapter joint 87 should increase the space of the overall connecting pipe body, thereby affecting the overall size of the machine table.

The present embodiment is to provide a pipe body fixing structure of an air conditioning machine, which can reduce the components required for connecting the pipe body, and can reduce the space occupied by the connecting pipe body.

In order to solve the above problems, the present invention provides a pipe body fixing structure of an air conditioning machine, which comprises a plate body, an elastic ring and a pipe body. The plate body has a cylindrical flange extending integrally from one side of the plate body, the inner diameter of the cylindrical flange being tapered from an end adjacent to the plate body toward an end away from the plate body; the elasticity The outer wall of the ring is elastically pressed against the inner wall surface of the cylindrical flange; the pipe body passes through the elastic ring; wherein the elastic ring is disposed between the pipe body and the cylindrical flange, and the inner wall surface of the elastic ring It is elastically pressed against the outer wall surface of the pipe body.

The beneficial effect of the creation is that the elastic ring is used to fix the plate body and the pipe body, so that the pipe body can be directly fixed and pierced, and no additional pressing joints or flanges are needed, thereby reducing the cost and reducing the occupied space; In addition, the construction method is simple, no welding is required, or multiple bolts are screwed to reduce the working hours of the construction.

As shown in Fig. 3, the present invention provides a pipe fixing structure 1 for an air conditioning machine, which is applied to an air conditioning machine such as a cooling water tower or an evaporative cooler. As shown in FIG. 3 and FIG. 4, the tube fixing structure 1 includes a plate body 10, a tube body 20 and an elastic ring 30. The plate body 10 is a casing portion of the aforementioned air conditioner. The pipe body 20 is used for the air conditioning machine to transfer fluid, and the pipe body 20 is disposed through the plate body 10 to facilitate the overall pipeline configuration of the air conditioning machine. The elastic ring 30 is disposed between the plate body 10 and the pipe body 20, so that the pipe body 20 can be stably disposed on the plate body 10. The plate body 10 is used to fix and support the tubular body 20 by the tubular body 10 being pierced by the tubular body 10.

As shown in Fig. 4, it is an exploded view of the fixed structure of the pipe body. The plate body 10 has a cylindrical flange 11 which is integrally formed by one side of the plate body 10. The outer wall of the elastic ring 30 closely abuts against the inner wall surface of the cylindrical flange 11. A first opening 12 is formed in the position of the cylindrical flange 11 adjacent to the plate body 10, and a second opening 13 is formed in the end of the cylindrical flange 11 away from the plate body 10. The first opening 12 and the second opening 13 are connected to each other. The pipe body 20 passes through.

Referring to Figure 7, there is a cross-sectional view according to Figure 4. The aperture D1 of the first opening 12 is larger than the aperture D2 of the second opening 13, and the inner diameter of the cylindrical flange 11 is tapered toward an end away from the board body 10 from an end close to the board body 10. In other words, the inner wall surface of the cylindrical flange 11 is inclined. The cylindrical flange 11 may be formed by drawing processing from the plate body 10, or may be press-formed (oil-pressed) by the plate body 10 such that the plate body 10 is joined to form a portion of the cylindrical flange 11 (ie, the first opening 12) The inside of the hole wall) forms a rounded surface.

Referring to FIG. 4 again, the pipe body 20 is provided with at least one anti-vortex hole 21, and the anti-vortex hole 21 is passed through the pipe wall of the pipe body 20, thereby increasing the passage of the fluid flow to avoid The flow rate is too fast to cause a vortex.

As shown in FIG. 5 and FIG. 6, the elastic ring 30 includes an annular pad 31 formed at one end thereof, a tightening cylinder 32 extending from one side of the annular pad 31, and a guiding portion 322. Formed at the end of the tightening cylinder 32. The outer diameter of the annular pad 31 is larger than the outer diameter of the tightening cylinder 32, and the inner diameter of the annular gasket 31 is equal to the inner diameter of the tightening cylinder 32. The length of the tightening cylinder 32 is greater than the length of the cylindrical flange 11. The elastic ring 30 has a substantially uniform inner diameter in an undeformed state. The guide portion 322 is formed to be inclined inwardly from the outer circumference of the tightening cylinder 32.

The inner diameter of the elastic ring 30 is slightly smaller than the outer diameter of the tubular body 20, whereby the tubular body 20 can be tightly fitted inside the tubular body 20. The outer diameter of the tightening cylinder 32 is slightly larger than the diameter of the second opening 13, whereby the elastic ring 30 can be tightly fixed to the cylindrical flange 11. The outer diameter of the annular pad 31 is larger than the diameter of the first opening 12. In the present embodiment, the elastic ring 30 is made of a rubber material, but is not limited to a rubber material, and a material that is impervious to water and has elasticity may be used to manufacture the elastic ring 30.

Referring to FIG. 4 and FIG. 7 , in the embodiment, the elastic ring 30 is provided with one end of the guiding portion 322 adjacent to the plate body 10 and facing the first opening 12 . Next, the tightening cylinder 32 passes through the first opening 12 and then through the second opening 13 such that the elastic ring 30 passes through the plate body 10 and the cylindrical flange 11. As described above, the inner side of the hole wall of the first opening 12 is a smooth surface, so that the guide portion 322 can pass through the cylindrical flange 11 more smoothly.

The annular pad 31 of the elastic ring 30 abuts against the plate body 10. Since the outer diameter of the annular pad 31 is larger than the aperture of the first opening 12, the annular pad 31 can close the gap between the elastic ring 30 and the wall of the hole of the first opening 12. Further, the annular pad 31 can restrict the displacement of the elastic ring 30 and prevent the liquid from flowing in from the aforementioned slit, thereby preventing the elastic ring 30 from coming loose and leaking.

As described above, since the cylindrical flange 11 has a tapered inner diameter, when the inner diameter of the cylindrical flange 11 is smaller than the outer diameter of the elastic ring 30, the outer wall surface of the elastic ring 30 is elastically urged to the cylindrical flange. The inner wall surface of the elbow, and the tightening cylinder 32 of the elastic ring 30 portion protrudes from the cylindrical flange 11. The wall of the second opening 13 is urged against the periphery of the tightening cylinder 32. And generally located in the middle of the elastic ring 30. Due to the elasticity of the elastic ring 30, the outer periphery of the tightening cylinder 32 abuts against the free end edge of the cylindrical flange 11. The wall of the second opening 13 is caught in the elastic ring 30, and the elastic ring 30 is not easily retracted from the cylindrical flange 11. Thereby, it is firmly caught in the cylindrical flange 11.

The difference in aperture between the first opening 12 and the second opening 13 of the present embodiment corresponds to the material and thickness of the elastic ring 30 to obtain a better frictional force. For example, the slope of the cylindrical flange 11 may be between about 1/8 and 1/12, based on a hypothetical plane perpendicular to the plate body 10. For the tubular body 20 having an inner diameter of one inch, the first The difference in aperture between the opening 12 and the second opening 13 may be approximately 1 mm.

When the elastic ring 30 is firmly disposed on the plate body 10 and the pipe body 20 passes through the elastic ring 30, the inner diameter of the elastic ring 30 is slightly smaller than the outer diameter of the pipe body 20, so that the pipe body 20 is also pressed by the elastic force generated by the deformation of the elastic ring 30. , to be firmly fixed in the elastic ring 30 in part. In order to fix the elastic body 30 tightly to the plate body 10, the friction coefficient between the elastic ring 30 and the plate body 10 and the pipe body 20 is large, so a lubricant can be used during the installation process (for example, : Oil) to reduce the coefficient of friction during installation. In the above installation process, the elastic ring 30 is first fixed on the plate body 10, and then the pipe body 20 is inserted into the elastic ring 30; the user can first insert the elastic ring 30 into the pipe body 20, and then fix the elasticity of the pipe body 20. The ring 30 is mounted on the board body 10.

As shown in Fig. 8, when the pipe body 20 is supplied with water from a water tank 9 by a pumping motor (not shown), the plate body 10 is the groove wall of the water tank 9 in Fig. 8. The portion of the tubular body 20 provided with the anti-vortex hole 21 directly passes through the elastic ring 30 and is immersed in the water, and the opening of the anti-vortex hole 21 faces downward. The function of the vortex prevention hole 21 is to prevent the pipe body 20 from drawing in air. When the water level of the water tank 9 is low, vortex is more likely to occur during the pumping process, and the generation of the vortex easily causes the tube body 20 to draw in air.

In this embodiment, when the pumping motor is pumping water through the pipe body 20, the water in the water tank 9 can pass through the through hole of the pipe body 20 and the anti-whirl hole 21, and the anti-whirl hole 21 can divert the water flow to avoid the pumping flow rate. Quickly create a vortex to prevent the water from drawing into the air. In addition, the opening of the anti-vortex hole 21 faces downward, and the anti-vortex hole 21 is away from the water. This configuration also reduces the chance of pumping in air.

It can be seen from the arrangement of the above-mentioned plate body 10, the tubular body 20 and the elastic ring 30 that the elastic ring 30 is used to fix the plate body 10 and the tubular body 20, and the tubular body 20 can directly pass through the elastic ring 30. This creation can save installation procedures and man-hours. It does not need to disassemble the pipe body in a conventional manner for multi-stage assembly, and can avoid a large amount of space occupied by multi-stage pipe assembly. In addition, the present invention uses the wall surface of the cylindrical flange 11 formed by the extension of the plate body 10 to press the elastic ring 30, that is, the fixing structure (the cylindrical flange 11) of the plate body 10 and the elastic ring 30 is looped on the elastic ring 30. And the elastic ring 30 is also sleeved on the pipe body 20, so the arrangement of the elastic ring 30 and the cylindrical flange 11 does not occupy excessive space on the periphery of the air conditioner. In other words, the tubular body 20 of the present invention can be bent immediately at the periphery of the plate body 10, and can be bent without additionally connecting an adapter. Compared with the traditional pipe fixing method, the pipe fixing structure 1 provided by the present invention can reduce the overall thickness, thereby reducing the overall size of the machine and saving the space for the machine, and reducing the number of components transferred. Reduce the manufacturing cost of the machine.

It can be known from the above that the pipe fixing structure provided by the present invention has at least the following advantages: the plate body and the pipe body are fixed by the elastic ring, so that the pipe body can be directly fixed and pierced without generating extra thickness; The two ends of the edge have a difference in aperture, and the one end aperture is slightly smaller than the outer diameter of the elastic ring, so that the elastic ring and the plate body are stably fixed; the elastic ring is provided with a guiding portion to facilitate the elastic ring to pass through the plate body; The arrangement allows the annular pad to close the gap and the displacement of the annular pad; the use of the anti-whirl hole arrangement avoids vortexing when pumping water and draws in air.

However, the above description is only the preferred embodiment of the present invention, and it is not intended to limit the scope of patent protection of this creation. Therefore, the equivalent changes made by using this creation specification and the contents of the schema are all included in the right of this creation. Within the scope of protection, it is given to Chen Ming.
