Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water pipe, especially a folding water passing channel structure. BACKGROUND

[0002] In a laboratory environment, the stability and reliability of the waterway connection system are of great importance. Although traditional fixed waterway connection structures are simple and reliable, they are not flexible enough when facing frequent replacement of laboratory equipment or adjustment of waterway layout. Therefore, some foldable or rotatable waterway connection structures have appeared on the market to meet the needs of flexibility and convenience in laboratories. However, these existing foldable or rotatable waterway connection structures still have some problems in internal sealing and reducing water flow impact.

[0003] For example, some structures have poor sealing performance and are prone to water leakage after long-term use or frequent folding and rotating, which not only affects the normal operation of the laboratory but also may cause damage to experimental equipment and experimental results. In addition, when water flows through the folding or rotating part, due to the change of pipe shape and the sharp change of water flow direction, a large water flow impact and noise are often generated, which not only disturbs the normal work of the experimental personnel but also may cause potential damage to the waterway system. SUMMARY

[0004] Therefore, the utility model aims to provide a folding water passing channel structure to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] The utility model provides a folding water passing channel structure, which comprises a water inlet pipe, an inlet hole is formed in the top of the water inlet pipe, a rotating shaft is inserted and fixedly connected in the water inlet pipe, an opening is formed in part of the circumferential side of the rotating shaft in the water inlet pipe, and the opening is communicated with the inlet hole through a communication port formed in the water inlet pipe.

[0007] A slot is formed in one side of the water inlet pipe, one end of the rotating shaft extends into the slot, and a water outlet pipe is rotationally connected to the slot, a water passing cavity is formed in the water outlet pipe and communicated with the rotating shaft, a water outlet hole is formed in the end of the water outlet pipe, and the water outlet hole is communicated with the water passing cavity.

[0008] Further, the water outlet pipe can rotate at any angle of 0-180 degrees with the rotating shaft as the rotation point in the slot.

[0009] Further, the part of the rotating shaft with the opening is located in the communication port, and the openings are spaced apart along the circumferential side of the rotating shaft.

[0010] Further, a plurality of inner grooves are arranged on the outer circumference of the rotating shaft at intervals, and a sealing ring is arranged in the inner grooves.

[0011] Further, a friction plate is arranged between the water outlet pipe and the slotted inner wall, and one side of the friction plate is fixedly connected to the slot.

[0012] Further, a pressure bearing is fixedly arranged on the side of the end of the rotating shaft away from the water outlet pipe, and a nut is screwed to the end of the rotating shaft.

[0013] The nut and the water inlet pipe sandwich the pressure bearing.

[0014] Further, a mounting shell is screwed to the end of the water inlet pipe away from the water outlet pipe.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] In the utility model, the water outlet pipe is rotatably connected between the rotating shaft and the water inlet pipe, which meets the requirement of flexible layout of the laboratory, and the water entering the water inlet pipe flows to the water outlet pipe, avoiding the direct flow of water from the water inlet pipe to the water outlet pipe, achieving smooth transition of the water flow, reducing the turbulence and vortex that may be generated in the turning process of the water flow, and thus reducing the impact of the water flow on the equipment.

[0017] The hole design on the rotating shaft not only helps the continuous flow of the water flow, but also disperses the water flow to some extent, so that the water flow is more uniformly distributed in the water outlet pipe. The dispersion reduces the direct impact of the water flow on the wall of the water outlet pipe, and reduces the noise and vibration generated by the impact of the water flow.

In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In addition, in the description of the present application, unless otherwise explicitly limited, the terms "mounting", "connecting", "connection", "connector" should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in conjunction with the specific circumstances.

[0028] The present application will be described in detail below with reference to the accompanying drawings Figures 1 to 4 and in conjunction with the embodiments.

[0029] Overall, the present application relates to a folding water passage structure, which includes an inlet pipe 1, the top of the inlet pipe 1 is provided with a water inlet hole 101, a rotating shaft 3 is inserted and fixedly connected in the inlet pipe 1, the part of the rotating shaft 3 located on the side of the inlet pipe 1 is provided with an opening 301, the opening 301 is communicated with the water inlet hole 101 through a communication port 102 formed in the inlet pipe 1;

[0030] A slot 103 is formed on one side of the inlet pipe 1, one end of the rotating shaft 3 extends into the slot 103, and an outlet pipe 2 is rotatably connected, a water passage 201 is formed in the outlet pipe 2 and is communicated with the rotating shaft 3, a water outlet hole 202 is formed at the end of the outlet pipe 2, and the water outlet hole 202 is communicated with the water passage 201.

[0031] In the embodiment, the water outlet pipe 2 is connected to the water inlet pipe 1 through the rotating shaft 3, which meets the flexible layout requirement of the laboratory. The water entering the water inlet pipe 1 will flow into the water outlet pipe 2, avoiding the water flowing directly from the water inlet pipe 1 into the water outlet pipe 2, realizing the smooth transition of the water flow, reducing the turbulence and vortex that may be generated in the turning process of the water flow, and thus reducing the impact of the water flow on the equipment.

[0032] As shown in Figure 2 and Figure 3 , the opening 301 on the rotating shaft 3 is designed not only to facilitate the continuous flow of water, but also to disperse the water flow to some extent, making it more evenly distributed in the water outlet pipe 2. This dispersion reduces the direct impact of the water flow on the wall of the water outlet pipe 2, reducing noise and vibration caused by the impact of the water flow.

[0033] Specifically, the water inlet pipe 1 and the water outlet pipe 2 are connected through the rotating shaft 3, avoiding the flow from the gap between the water inlet pipe 1 and the water outlet pipe 2, and increasing the sealing of the overall pipeline. When installing, the water inlet pipe 1 is installed in close contact with the water outlet pipe 2.

[0034] It should be noted that the water flow enters the water inlet pipe 1 through the water inlet hole 101, then enters the communication port 102, enters the rotating shaft 3 through the opening, enters the water passage 201 of the water outlet pipe 2 through the rotating shaft 3, and finally flows out of the water outlet pipe 2 through the water outlet hole 202. This process realizes the change of the water flow direction.

[0035] As preferred, as shown in Figure 2 and Figure 4 , the water outlet pipe 2 can rotate in the slot 103 with the rotating shaft 3 as the rotation point at any angle of 0-180 degrees. In this way, the flexibility and adaptability of the waterway are increased. Laboratory personnel can adjust the waterway direction according to actual needs, improving work efficiency and convenience.

[0036] It should be noted that the rotation angle of the water outlet pipe 2 in the slot 103 is determined according to the size of the slot 103, and the size of the slot 103 can be adjusted according to the actual situation, which is not limited further herein.

[0037] Based on the above setting, as shown in Figure 2 , the part of the rotating shaft 3 with the opening is located in the communication port 102, and the openings are spaced apart along the circumferential side of the rotating shaft 3. In this way, the continuity and uniformity of the water flow when entering the rotating shaft 3 are ensured, and the turbulence and impact caused by the water flow are reduced.

[0038] In order to further increase the sealing of the rotating shaft 3, in the embodiment, a plurality of inner grooves 302 are arranged on the outer circumference of the rotating shaft 3 at intervals, and a sealing ring 303 is arranged in the inner groove 302. The sealing ring 303 arranged in the inner groove 302 effectively enhances the sealing performance between the rotating shaft 3 and the water inlet pipe 1, and prevents water leakage. The safety and reliability of the waterway system are improved, and the normal operation of the laboratory is ensured.

[0039] In order to facilitate the positioning of the water outlet pipe 2 after the rotation angle, in the embodiment, a friction plate 4 is arranged between the water outlet pipe 2 and the inner wall of the slot 103, one side of the friction plate 4 is fixedly connected with the slot 103, and the other side is abutted with the side wall of the water outlet pipe 2. In specific implementation, the friction plate 4 increases the friction between the water outlet pipe 2 and the slot 103, and after the angle is adjusted, the position is limited by the friction.

[0040] It should be further explained that when assembling, after the water outlet pipe 2 and the rotating shaft 3 are mounted together, the water inlet pipe 1 is finally assembled, and the other end of the rotating shaft 3 is inserted into the water inlet pipe 1. In order to facilitate the stable installation of the rotating shaft 3 in the water inlet pipe 1 and the water outlet pipe 2, in the embodiment, a pressure bearing 304 is fixedly arranged on the side of the end of the rotating shaft 3 away from the water outlet pipe 2, and a nut 305 is screwed on the end of the rotating shaft 3.

[0041] In specific implementation, as shown in Figure 2 and Figure 3 by screwing the nut 305 towards the water outlet pipe 2, the pressure bearing 304 is squeezed, and finally the nut 305 and the water inlet pipe 1 clamp the pressure bearing 304 in the middle, not only fixing the rotating shaft 3, but also increasing the friction between the water outlet pipe 2 and the water inlet pipe 1.

[0042] In addition, the end of the water inlet pipe 1 away from the water outlet pipe 2 is screwed with a mounting shell 5, and the mounting shell 5 can wrap the nut 305 and the pressure bearing 304 to form protection.

[0043] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
