Description

Technical Field

[0001] This utility model relates to the field of expansion joints for floor drains used in the production of precast components, and more particularly to an expansion joint for floor drains used in the production of precast components. Background Technology

[0002] With the continuous enrichment of building decoration techniques, changes in the ground structure during construction have become the primary challenge that traditional floor drains struggle to adapt to. In the decoration process, the cement mortar bedding layer used when laying floor tiles, as well as the thickness of the floor tiles themselves, will significantly raise the ground elevation. For example, in residential decoration, a typical floor tile laying operation may raise the ground by three to five centimeters. This causes traditional fixed-height floor drains that are pre-installed to experience poor drainage or even backflow because their height does not match the new ground. To solve this problem, a prefabricated component floor drain expansion device has been developed.

[0003] An innovative adjustable-height drainage component for prefabricated component production floor drain expansion device is mainly used to solve the problem of thickness differences in different ground structure layers in modern decoration. It can perfectly adapt to the installation needs of various ground structures such as tiles, waterproof layers, and mortar leveling layers, ensuring seamless connection between the floor drain body and the building drainage pipes. While ensuring smooth drainage, it effectively prevents leakage problems. The installation process is not limited by the final finished height of the ground, greatly improving the flexibility and reliability of construction. It is suitable for various building scenarios such as new house decoration, old house renovation, and commercial spaces.

[0004] While a current type of expansion joint for precast component production floor drains can compensate for the displacement of the pipeline system and ensure smooth drainage and leak-proof sealing, the lack of reserved expansion allowance or complete compression or stretching to the limit during installation can lead to problems such as the device being unable to expand or contract, resulting in slower drainage or even complete blockage. The expansion joint may also sag or experience uneven stress, significantly affecting drainage. Cleaning the pipes requires damaging the floor drain fixture. Therefore, a new expansion joint for precast component production floor drains is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a floor drain expansion device for prefabricated component production, which aims to improve the problems of existing devices being unable to expand or contract, resulting in slow drainage speed or even complete blockage, and the expansion device sagging or uneven force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A retractable drain device for prefabricated component production includes a drain cover, a piston fixedly connected to the bottom of the drain cover, support columns fixedly connected to all four sides of the bottom of the drain cover, limit columns slidably connected to the inner walls of the four support columns, water inlets fixedly connected to the bottom of the four limit columns, four support square columns fixedly connected to the outer walls of the water inlets, a drain shell fixedly connected to the outer side of the support square columns, a water storage tank fixedly connected inside the drain shell, springs sleeved on the outer walls of the limit columns, and a fixing component fixedly connected to the bottom of the water inlets.

[0008] As a further description of the above technical solution:

[0009] The fixing assembly includes a connecting shaft, the top of which is fixedly connected to the bottom of the water inlet. Four fixing brackets are fixedly connected to the bottom of the connecting shaft. A fixing control rod is fixedly connected to the outer side of each of the four fixing brackets. A connecting bracket is rotatably connected to the bottom of each of the four fixing control rods. A support rod is rotatably connected to the bottom of each of the four connecting brackets. A fixed frame rotating shaft is fixedly connected below the connecting shaft. A threaded water pipe is fixedly connected to the bottom of the fixed frame rotating shaft. A movable nut is threaded onto the outer wall of the threaded water pipe.

[0010] As a further description of the above technical solution:

[0011] The four support rods are all fixedly connected to the outer wall of the movable nut on their adjacent sides, and the cross-sectional shape of the connecting bracket is H-shaped;

[0012] As a further description of the above technical solution:

[0013] The top of the fixed control rod is fixedly connected to the bottom of the support column, and the top of the movable nut is in contact with the bottom of the fixed frame rotating shaft;

[0014] As a further description of the above technical solution:

[0015] The bottom of the drain cover is in contact with the top of the drain housing, and the outer wall of the piston is in contact with the inner wall of the water inlet;

[0016] As a further description of the above technical solution:

[0017] The top of the spring is fixedly connected to the bottom of the support column, and the bottom of the spring is fixedly connected to the top of the water inlet.

[0018] As a further description of the above technical solution:

[0019] The top of the supporting column is in contact with the bottom of the water storage tank, and the inner wall of the water storage tank is provided with through holes.

[0020] As a further description of the above technical solution:

[0021] The bottom of the piston is in contact with the top of the connecting shaft, and the top of the limiting post is in contact with the bottom of the drain cover.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model provides an innovative press-type drain cleaning mechanism. When the user presses the drain cover vertically, the rigidly connected piston assembly will complete reciprocating motion under the precise guidance of the three-point positioning system. The central connecting shaft provides the main axial guidance, and the annular limiting structure set on the inner wall of the inlet further ensures the stability of the movement trajectory. The sealed chamber formed by the outer wall of the piston and the inlet will generate significant periodic pressure fluctuations. Combined with the specially designed stepped turbulence protrusion structure at the bottom of the piston, it effectively decomposes and removes common blockages such as hair and soap scum accumulated in the pipe.

[0024] 2. This utility model employs an innovative rotary transmission mechanism. Rotating the drain cover drives the support base and limiting post to work together, precisely driving the water inlet to rotate. The rotation of the water inlet is transmitted to the fixed bracket via a rotating shaft, forming a linked rotary mechanism between the fixed bracket and the fixed control pipe. This rotary mechanism further drives the support rod to move precisely through a connecting bracket, ultimately allowing the movable nut to move controllably up and down on the outside of the threaded water pipe. This unique mechanical transmission design enables rapid installation and disassembly of the entire structure, offering advantages such as ease of operation, accurate positioning, and reliable connection.

Water inlets 5 are fixedly connected to the bottom of the four limiting columns 17. The water inlets 5 adopt a gradually expanding design to improve drainage efficiency. Four supporting square columns 6 are fixedly connected to the outer walls of the water inlets 5. The supporting square columns 6 have internal reinforcing ribs to enhance load-bearing capacity. A drain housing 15 is fixedly connected to the outside of the supporting column 6. The drain housing 15 is treated with anti-corrosion to extend its service life. A water storage tank 16 is fixedly connected inside the drain housing 15. The bottom of the water storage tank 16 is designed with a slope to facilitate the sedimentation of impurities. A spring 4 is sleeved on the outer wall of the limiting column 17. The spring 4 is made of stainless steel to ensure lasting elasticity. The outer wall of the piston 2 is in contact with the inner wall of the water inlet 5. The contact surface adopts a conical sealing structure to ensure complete waterproofing. The top of the spring 4 is fixedly connected to the bottom of the supporting column 3. The connection is equipped with an anti-disengagement buckle to prevent the spring 4 from shifting. The bottom of the spring 4 is fixedly connected to the top of the water inlet 5. The mounting base at the bottom of the spring 4 is precision machined to ensure uniform force distribution.

[0034] Reference Figure 4 and Figure 5In one embodiment of this utility model, a fixing assembly is fixedly connected to the bottom of the inlet 5. The fixing assembly includes a connecting shaft 7. The top of the connecting shaft 7 is fixedly connected to the center of the bottom of the inlet 5 to ensure a complete seal at the connection. Four fixing brackets 8 are fixedly connected to the bottom of the connecting shaft 7. The fixing brackets 8 are distributed in a cross-shaped symmetrical pattern at the bottom of the connecting shaft 7. The surface of the brackets is treated with rust prevention. Fixing control rods 9 are fixedly connected to the outer walls of the four fixing brackets 8. The bottoms of the four fixing control rods 9 are rotatably connected to the connecting brackets 1 via universal joints. 1. The connecting bracket 11 can rotate 180 degrees with the bottom of the fixed control rod 9. The bottom of each of the four connecting brackets 11 is rotatably connected to a support rod 12. The connecting bracket 11 can rotate flexibly through the support rod 12. The fixed frame rotating shaft 10 is fixedly connected below the connecting shaft 7. The fixed frame rotating shaft 10 can prevent the entire component from axial displacement. The bottom of the fixed frame rotating shaft 10 is fixedly connected to a threaded water pipe 14. Several turns of Teflon tape are wrapped around the thread to prevent water leakage. The outer wall of the threaded water pipe 14 is fixedly connected to a movable nut 13. The movable nut 13 can also be manually adjusted.

[0035] Reference Figures 3 to 5 The four support rods 12 are fixedly connected to the outer wall of the movable nut 13 on their adjacent sides. The connection is made of integrated laser welding to ensure structural strength. The cross-sectional shape of the connecting bracket 11 is H-shaped. The top of the fixed control rod 9 is fixedly connected to the bottom of the support column 6 and is fixed with anti-loosening bolts. The top of the movable nut 13 and the bottom of the fixed frame rotating shaft 10 can contact each other. When the contact surfaces are in contact, they can ensure perfect fit. The top of the fixed control rod 9 is fixedly connected to the bottom of the support column 6. The top of the movable nut 13 and the bottom of the fixed frame rotating shaft 10 can contact each other. The bottom edge of the drain cover 1 and the top part of the drain shell 15 will also contact each other when pressed. The outer wall of the piston 2 contacts the inner wall of the inlet 5. The outer wall of the piston 2 is made of elastic rubber material and its surface is designed with an annular sealing groove, which fits precisely with the inner wall of the inlet 5 to form a reliable piston 2 sealing structure.

[0036] according to Figures 1 to 3 The top of the spring 4 is fixedly connected to the bottom of the support column 3. The spring 4 can rebound when the customer presses and releases the drain cover 1, so that the drain cover 1 returns to its original position. The bottom of the spring 4 is fixedly connected to the top of the water inlet 5. The top of the support column 6 is in contact with the bottom of the water tank 16. A buffer pad is provided on its contact surface to reduce wear on the drain cover 1 when it is pressed. The inner wall of the water tank 16 is provided with a through hole, through which a removable filter screen can be installed. The bottom of the piston 2 is in contact with the top of the connecting shaft 7 and adopts a sealed structure. The top of the limiting column 17 is in contact with the bottom of the drain cover 1 and can make contact when it is pressed to the limit value.

[0037] Working principle: By pressing the drain cover 1, the user can cause the piston 2 to enter the inlet 5 under the action of the support column 3 and the limiting column 17. The piston 2 then enters the inlet 5 and performs a squeezing reciprocating motion at the top of the connecting shaft 7 via the spring 4. This motion can clear the dirt inside the threaded water pipe 14, preventing blockage. Alternatively, by rotating the drain cover 1, the support column 6 can drive the connecting shaft 7 and the fixed bracket 8, causing the fixed bracket rotating shaft 10 to rotate the threaded water pipe 14. This allows the movable nut 13 to retract or extend through the rotational connection between the support rod 12 and the connecting bracket 11. This action allows the connecting bracket 11 to be fixed or disassembled through the linkage between the fixed control rod 9 and the support rod 12, thus greatly improving the practicality of the entire drain.
