Description

Technical Field

[0001] This application relates to the field of water tanks, and more particularly to a drainage tank. Background Technology

[0002] Drainage tanks are suitable for various applications. In related technologies, a drainage tank includes a tank body and a drain pipe. The tank body has a drain outlet, and the drain pipe connects to the tank body. Water flows from the outlet along the drain pipe into a receiving container. The drain pipe protrudes from the drainage tank and is exposed. During drainage, the drain pipe is prone to collisions with other objects. The force of these collisions acts on the connection between the drain pipe and the tank body. With increased use, the structural strength of this connection decreases, making it prone to bending and causing water to leak directly from the drain outlet, necessitating replacement of the drainage tank. The service life of drainage tanks needs to be improved. Summary of the Invention

[0003] In order to improve the service life of the drainage tank, this application provides a drainage tank.

[0004] The drainage tank provided in this application adopts the following technical solution:

[0005] A drainage tank includes a tank body, a connecting block disposed on the tank body, and a water outlet pipe disposed on the connecting block. The connecting block has a drain outlet, and the water outlet pipe communicates with the interior of the tank body through the drain outlet. The tank body is provided with a limiting ring, which surrounds the outer periphery of the connecting block and is used to abut against the water outlet pipe.

[0006] By adopting the above technical solution, when in use, the water outlet pipe is sleeved on the connecting block, and the outer peripheral wall of the connecting block is in contact with the inner wall of the water outlet pipe. At this time, the end of the water outlet pipe connected to the connecting block is located between the connecting block and the limiting ring. When the water outlet pipe collides with other objects, the limiting ring abuts against the water outlet pipe, reducing the shaking amplitude at the connection between the water outlet pipe and the connecting block, making the connecting block less prone to bending, improving the service life of the connecting block, and thus improving the service life of the drainage tank.

[0007] Preferably, the limiting ring has an opening at one end near the housing, and the opening is connected to the drain outlet.

[0008] By adopting the above technical solution, the water outlet pipe is fitted onto the connecting block. When it is necessary to remove the water outlet pipe from the connecting block, a tool or hand is inserted into the opening and inserted between the water outlet pipe and the box. The tool or hand abuts against the end of the water outlet pipe near the box, causing the end of the water outlet pipe to move away from the box and detach from the connecting block, making it convenient to remove the water outlet pipe from the connecting block.

[0009] Preferably, the water outlet pipe is provided with a limiting surface, which is used to abut against the connecting block. When the limiting surface abuts against the connecting block, the water outlet pipe is spaced apart from the box body.

[0010] By adopting the above technical solution, when the water outlet pipe is fitted onto the connecting block, the connecting block extends into the water outlet pipe and fits against the limiting surface, preventing the connecting block from extending further into the water outlet pipe. At this time, there is a gap between the end of the water outlet pipe and the box body, which makes it easier for tools or hands to reach into the opening and abut against the end of the water outlet pipe, making it easier for the water outlet pipe to detach from the connecting block.

[0011] Preferably, a plurality of rotating rods are hinged to the limiting ring, and the plurality of rotating rods are distributed around the outer periphery of the connecting block. The rotating rods rotate to move closer to or away from the water outlet pipe. The rotating rods are provided with sealing elements, and the plurality of sealing elements are spliced ​​together to form a sealing ring, which is used to press against the water outlet pipe.

[0012] By adopting the above technical solution, after the water outlet pipe is fitted into the connecting block, several rotating rods rotate and approach the water outlet pipe. The sealing parts on the rotating rods are spliced ​​together to form a sealing ring, which presses against the water outlet pipe. By pressing the water outlet pipe against the sealing parts, it is beneficial to reduce the shaking amplitude when the water outlet pipe collides with other objects, and thus it is beneficial to reduce the shaking amplitude of the connecting block.

[0013] Preferably, the rotating rod is provided with a push block, the push block is located on the moving path of the water outlet pipe, and the push block abuts against the water outlet pipe.

[0014] By adopting the above technical solution, during the installation of the water outlet pipe, as the connecting block extends into the water outlet pipe, the water outlet pipe abuts against the push-pull block, causing the push block to rotate towards the housing. The rotating rod drives the sealing element to press against the water outlet pipe, increasing the connection strength between the water outlet pipe and the connecting block. When it is necessary to remove the water outlet pipe, a tool or hand is inserted through the opening to abut against the push block, causing the push block to rotate away from the housing. The push block abuts against the water outlet pipe and moves away from the housing. During the process of the water outlet pipe moving away from the connecting block, the rotating rod rotates away from the water outlet pipe, causing the sealing element to disengage from the water outlet pipe. This helps to reduce the resistance encountered when the water outlet pipe moves away from the connecting block, making it easier for the water outlet pipe to disengage from the connecting block.

[0015] Preferably, the rotating rod is provided with a handle, the handle and the push block are respectively located on opposite sides of the rotating rod, and the handle extends out of the limiting ring from the through-hole.

[0016] By adopting the above technical solution, when it is necessary to remove the water outlet pipe from the connecting block, press the handle to rotate the handle downwards, and the push block will rotate upwards against the end of the water outlet pipe, so that the connecting block gradually separates from the water outlet pipe. No additional tools are needed, making it easier to remove the water outlet pipe from the connecting block.

[0017] Preferably, the height of the limiting ring is greater than 3 / 4 of the height of the connecting block.

[0018] By adopting the above technical solution and increasing the height of the limiting ring, it is beneficial to reduce the shaking amplitude of the connecting block and the water outlet pipe, thereby improving the connection stability between the connecting block and the box.

[0019] Preferably, there is a gap between the limiting ring and the water outlet pipe.

[0020] By adopting the above technical solution, the distance between the connecting block and the limiting ring is greater than the wall thickness of the water outlet pipe, which helps to reduce the resistance encountered when the water outlet pipe is fitted into the connecting block.

[0021] Preferably, the housing has a recessed area, and the limiting ring and the connecting block are both located within the recessed area.

[0022] By adopting the above technical solution, the water outlet pipe is usually transported separately from the tank body during the transportation process. By setting the limiting ring and connecting block in the recessed area of ​​the drainage tank, the limiting ring and connecting block do not protrude from the tank body, which facilitates the stacking of tank bodies and makes transportation convenient. In addition, it also reduces the possibility of the limiting ring and connecting block being damaged by collision with adjacent tank bodies during transportation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the water outlet pipe collides with other objects, the limiting ring abuts against the water outlet pipe, reducing the shaking amplitude at the connection between the water outlet pipe and the connecting block, making the connecting block less prone to bending, improving the service life of the connecting block, and thus improving the service life of the drain tank.

[0025] 2. The connecting block extends into the water outlet pipe and fits against the limiting surface. At this time, there is a gap between the end of the water outlet pipe and the box body, which makes it easier for tools or hands to reach into the opening and abut against the end of the water outlet pipe, making it easier for the water outlet pipe to detach from the connecting block.

[0026] 3. As the connecting block extends into the water outlet pipe, the water outlet pipe abuts against the push-pull block, causing the push block to rotate towards the housing. The rotating rod drives the sealing element to press against the water outlet pipe, increasing the connection strength between the water outlet pipe and the connecting block.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a drainage tank. (Refer to...) Figure 1 and Figure 2 A drainage tank includes a tank body 1, a connecting block 2, and a water outlet pipe 3. One outer side wall of the tank body 1 is recessed inward to form a recessed area 11. The connecting block 2 is located within the recessed area 11 and is cylindrical in shape. The connecting block 2 is integrally formed with the tank body 1. One end of the water outlet pipe 3 is fitted onto and fixed to the connecting block 2, and the outer wall of the connecting block 2 is in contact with the inner wall of the water outlet pipe 3. A drain outlet 21 is provided on the connecting block 2, which communicates with the interior of the tank body 1. The water outlet pipe 3 is also connected to the interior of the tank body 1 through the drain outlet 21. A valve 31 is fixed on the water outlet pipe 3, and the valve 31 controls the opening and closing of the water outlet pipe 3.

[0033] In the actual processing, a water inlet is also provided on the box 1, through which water is injected into the box 1.

[0034] Reference Figure 1 and Figure 2 A limiting ring 4 is fixed on the housing 1. The limiting ring 4 is located in the recessed area 11. The limiting ring 4 is arranged around the outer periphery of the connecting block 2. The connecting block 2 and the limiting ring 4 are spaced apart. After the water outlet pipe 3 is fixed to the connecting block 2, the limiting ring 4 is used to abut against the water outlet pipe 3 to limit the shaking amplitude of the water outlet pipe 3. The height of the limiting ring 4 is greater than 3 / 4 of the height of the connecting block 2. In this embodiment, the height of the limiting ring 4 is the same as the height of the connecting block 2.

[0035] Reference Figure 1 and Figure 3 The gap between the connecting block 2 and the limiting ring 4 is greater than the wall thickness of the water outlet pipe 3. When the water outlet pipe 3 is fitted onto the connecting block 2, there is a gap between the water outlet pipe 3 and the inner wall of the limiting ring 4. This reduces friction between the limiting ring 4 and the water outlet pipe 3 during the process of fixing the water outlet pipe 3 to the connecting block 2, making it easier to fit the water outlet pipe 3 onto the connecting block 2. In this embodiment, after the water outlet pipe 3 is fixed onto the connecting block 2, the gap between the water outlet pipe 3 and the inner wall of the limiting ring 4 is 2mm.

[0036] Reference Figure 1 and Figure 3 The limiting ring 4 has two openings 41 at one end near the housing 1. The limiting ring 4 and the connecting block 2 are spliced ​​to form an installation groove 42, and the openings 41 communicate with the installation groove 42. When the water outlet pipe 3 is fixed to the connecting block 2, the end of the water outlet pipe 3 is located in the installation groove 42. The two openings 41 are located on opposite sides of the connecting block 2. After the water outlet pipe 3 is fixed to the connecting block 2, the projection of the end of the water outlet pipe 3 near the housing 1 in the radial direction of the connecting block 2 is located in the opening 41.

[0037] In this embodiment, the limiting ring 4 can also be formed by splicing two identical half-rings, with the two half-rings spaced apart, and the gap between the two half-rings serving as the opening 41.

[0038] Reference Figure 1 and Figure 3 Two slots 43 are formed on the inner wall of the limiting ring 4. The distribution direction of the slots 43 is consistent with the distribution direction of the openings 41. The slots 43 and the openings 41 are spaced apart. A rotating rod 5 is hinged to the limiting ring 4. The position and number of the rotating rods 5 correspond one-to-one with the position and number of the slots 43. The rotating rods 5 are evenly distributed around the outer circumference of the connecting block 2. The rotating rods 5 are hinged to the limiting ring 4 through a rotating shaft. The slots 43 are used for the corresponding rotating rods 5 to be engaged. The hinge axis of the rotating rod 5 is horizontal and perpendicular to the radial direction of the limiting ring 4. Rotate the rod 5 to move closer to or away from the water outlet pipe 3. The rotating rod 5 is engaged or disengaged from the slot 43. A sealing element 51 is fixed on the side of the rotating rod 5 that is close to the water outlet pipe 3. The sealing element 51 is semi-circular. When the two rotating rods 5 are rotated towards the water outlet pipe 3, the sealing elements 51 on the two rotating rods 5 come closer to each other. When the two sealing elements 51 are in contact with the outer wall of the water outlet pipe 3, the two sealing elements 51 abut each other to form a sealing ring 52. The inner wall of the sealing ring 52 presses against the water outlet pipe 3, increasing the connection stability between the water outlet pipe 3 and the connecting block 2, so that the water outlet pipe 3 is not easy to shake when it is hit.

[0039] Reference Figure 1 and Figure 3 A limiting surface 32 is formed on the inner wall of the water outlet pipe 3. The limiting surface 32 is used to fit the end of the connecting block 2 away from the box 1. After the water outlet pipe 3 is sleeved and fixed onto the connecting block 2, the end of the connecting block 2 away from the box 1 fits against the limiting surface 32. At this time, the water outlet pipe 3 is spaced apart from the box 1, and there is a gap between the end face of the water outlet pipe 3 near the box 1 and the box 1. At this time, the projection of the end of the water outlet pipe 3 near the box 1 in the radial direction parallel to the limiting ring 4 is located in the opening 41. This facilitates the insertion of tools from the channel to abut against the end face of the water outlet pipe 3.

[0040] Reference Figure 1 and Figure 3A push block 53 is fixed on the rotating rod 5. The push block 53 is located on the side of the rotating rod 5 closest to the connecting block 2. The angle formed by the push block 53 and the rotating rod 5 is a right angle. When the water outlet pipe 3 is fixed on the connecting block 2, the sealing ring 52 abuts against the outer wall of the water outlet pipe 3. The push block 53 is located on the moving path of the water outlet pipe 3, and the end of the push block 53 away from the housing 1 abuts against the end face of the water outlet pipe 3. The push block 53 rotates away from the housing 1, causing the rotating rod 5 to rotate away from the water outlet pipe 3 and engage in the corresponding slot 43.

[0041] Reference Figure 1 and Figure 3 A handle 54 is fixed on the rotating rod 5. The handle 54 and the push block 53 are located on opposite sides of the rotating rod 5. The handle 54 extends the limiting ring 4 from the corresponding port 41. There is a gap between the handle 54 and the box 1. The handle 54 rotates towards the box 1, causing the push block 53 to abut against the water outlet pipe 3 and move away from the box 1, making it easier to disassemble the water outlet pipe 3.

[0042] The implementation principle of a drainage tank according to an embodiment of this application is as follows: In actual use, the outlet pipe 3 is inserted into the connecting block 2. During the process of the connecting block 2 extending into the outlet pipe 3, the end face of the outlet pipe 3 abuts against the push block 53, causing the push block 53 to rotate towards the tank body 1. This causes the rotating rod 5 and the sealing member 51 to rotate and move closer to the outlet pipe 3, thus moving the sealing member 51 closer to the outlet pipe 3. When the end face of the connecting block 2 is in contact with the limiting surface 32, the sealing member 51 presses against the outlet pipe 3, increasing the connection strength between the outlet pipe 3 and the connecting block 2. This helps to reduce the shaking amplitude of the outlet pipe 3 and the connecting block 2 when the outlet pipe 3 is hit, making the connecting block 2 less prone to damage and improving the service life of the drainage tank.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
