Description

Technical Field

[0001] The present invention relates to the field of floor drain fittings, and particularly to a same-floor drainage floor drain support member. Background Art

[0002] As an important system for the normal operation of buildings, the drainage system is closely related to people's lives. As a drainage fitting connecting the ground to the drain pipe, the floor drain is commonly used in places such as bathrooms, shower rooms, and factories. The connection method between the floor drain and the drain pipe directly affects the drainage speed and the effect of odor control.

[0003] During the construction of current floors, before installing the floor drain, construction workers need to pre-dig a receiving groove for accommodating the floor drain, then backfill it with cement mortar to fix the drain pipe, and finally place the floor drain in the above-mentioned receiving groove and connect it to the drain pipe.

[0004] An assembled integral bathroom refers to an independent bathroom module assembled by on-site assembly or integral hoisting. To improve the installation efficiency, one of its advantages is that it does not involve cement mortar construction. Therefore, the above-mentioned method of connecting the floor drain and the drain pipe is not applicable to assembled integral bathrooms.

[0005] Assembled integral bathrooms usually adopt the same-floor drainage method for drainage. Their pipes and floor drains are arranged in an overhead layout form, and the floor drain and the drain pipe are connected by means of pipe docking. Therefore, there is no need for cement mortar backfill. For example, the Chinese patent with the patent number CN201410301792.6 discloses an integral bathroom with a same-floor drainage device, including a main drain pipe, a bathroom waterproof base, and a drain pipe connected to the main drain pipe. The bathroom waterproof base is provided with a plurality of installation holes and a floor drain installation hole for installing the floor drain. A floor drain communicating with the drain pipe is installed at the floor drain installation hole. The floor drain is clamped in the floor drain installation hole through a clamping groove thereon. The drainage cavity of the floor drain body is communicated with the drainage channel through a connecting cavity, and then installed on the ground.

[0006] In the above overhead layout form, the following problems exist: After the drain pipe and the floor drain are directly conducted through the connecting wall, the water flow discharged from the floor drain is likely to vibrate due to the floor drain being suspended, which will cause the connecting part between the suspended pipe and the floor drain to be stressed. After long-term use, the connection part is likely to become loose, resulting in water seepage.

[0007] To solve the above problems, construction workers often add gaskets under the floor drain main body to ensure that the floor drain is supported. However, the above adjustment method requires repeated debugging back and forth, and the floor drain sizes for pipe docking at different overhead heights are also different. Using the above adjustment method also causes the installation process to be too complicated, and the gaskets are prone to position deviation, and the connection part will become loose during subsequent use, resulting in water seepage. Summary of the Invention

[0008] To solve the above problems, the present invention provides a same-floor drainage floor drain support for supporting and adjusting floor drains of different sizes, avoiding loosening at the pipe connection and reducing the probability of water seepage.

[0009] The inventor found that prefabricated integral bathrooms usually adopt the same-floor drainage method for side drainage, and their pipes and floor drains are arranged in an overhead layout. The reasons for water seepage include the following two: First, during the installation process, the connection between the floor drain and the already connected pipe rotates, causing loosening at the connection. Second, during use, after the drain pipe and the floor drain are directly conducted through the connecting wall, the water flow discharged from the floor drain is prone to vibration when passing through because the floor drain is suspended, which will cause stress on the connection part between the suspended pipe and the floor drain. Long-term use is likely to cause loosening at the connection, thereby causing water seepage; therefore, it is necessary to support and level the floor drain. However, for the actual situation of the same-floor drainage system of prefabricated integral bathrooms, since the overhead height of the pipes will change according to requirements, the depths of the connected floor drains are different, which increases the difficulty in solving the technical problems of leveling and supporting the floor drain.

[0010] The technical solution of the present invention is a same-floor drainage floor drain support, which includes a top tray provided with a through hole, and a support assembly fixedly connected to the bottom of the top tray. The support assembly includes several support rods, a floor drain tray, and an adjusting member for adjusting the relative position of the floor drain tray and the support rods. The adjusting member includes a bearing with a nut fixedly connected to the inner ring. The outer wall of the support rod is provided with an external thread matching the nut, and the end point of the floor drain tray is movably connected to the outer wall of the bearing. There are at least 3 end points of the floor drain tray.

[0011] Preferably, the floor drain tray is provided with a shock-absorbing layer.

[0012] Preferably, the end point of the floor drain tray is hinged to the outer wall of the bearing.

[0013] Preferably, the support rod is a telescopic rod.

[0014] Preferably, the telescopic rod includes an inner rod, an outer rod sleeved on the outer wall of the inner rod, and the inner rod and the outer rod are connected by threads.

[0015] Preferably, the outer rod is provided with a fastener for stopping the inner rod.

[0016] Preferably, the fastener includes a hoop and a stop rod fixedly connected to the end face of the hoop. The support rod is provided with two slits, and the stop rod radially penetrates through the slits at the same time.

[0017] Preferably, the floor drain tray is a triangular supporting piece.

[0018] Preferably, the triangular supporting piece is an equilateral triangular supporting piece.

[0019] Preferably, a base is provided at the end of the support rod.

[0020] Preferably, the support rod is provided with scales.

[0021] The beneficial effects of the present invention are as follows:

[0022] By adjusting the adjusting member, the floor drain tray is moved in the vertical direction of the support rod to achieve stepless adjustment, so as to support floor drains of different sizes, reduce the vibration caused by the drainage of the floor drain, avoid loosening at the pipe connection, and reduce the probability of water seepage;

[0023] The multiple end points of the floor drain tray are movably connected to the outer wall of the bearing, so as to level the floor drains of different sizes, avoid loosening and water seepage caused by rotation and deviation from the pipeline during the installation process, and the leveling efficiency is high.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the drawings, but the embodiments of the present invention are not limited thereto.

[0034] The inventor found that prefabricated integral bathrooms usually adopt the same-floor drainage method for side drainage, and the layout of its pipes and floor drains is in an overhead arrangement form. The reasons for water seepage include the following two: First, during the installation process, the connection between the floor drain and the already connected pipe rotates, causing loosening at the connection. Second, during use, after the drain pipe and the floor drain are directly conducted through the connecting wall, when the water flow discharged from the floor drain passes through, vibration is easily generated due to the floor drain being suspended, which will cause stress on the connection part between the suspended pipe and the floor drain. Long-term use is likely to cause loosening at the connection, and thus water seepage occurs; therefore, it is necessary to support and level the floor drain. However, considering the actual situation of the same-floor drainage system of prefabricated integral bathrooms, since the overhead height of the pipes will change according to requirements, the depths of the connected floor drains are different, which increases the difficulty in solving the technical problems of leveling and supporting the floor drain.

[0035] Based on the above technical problems, as Figure 1As shown in the figure, the present application provides a same-floor drainage floor drain support member, which includes a top tray 1 provided with a through hole 11, and a support assembly 2 fixedly connected to the bottom of the top tray 1. The size of the through hole 11 is larger than the diameter of the actually used floor drain, so that the floor drain can be inserted into the same-floor drainage floor drain support member. The support assembly 2 includes a plurality of support rods 21, a floor drain tray 22, and an adjusting member 23 for adjusting the relative position between the floor drain tray 22 and the support rods 21. The number of the support rods 21 corresponds to the number of the end points of the floor drain tray 22. The support assembly 2 is fixedly connected to the bottom of the top tray 1 and the ends of the support rods 21. The fixing method can be welding or integral molding, etc. The fixing position is the outer edge of the bottom of the top tray 1. The adjusting member 23 includes a bearing 25 with a nut 24 fixedly connected to the inner ring. The fixing method can be welding or integral molding. The fixing position is the end face of the nut 24 and the end face of the inner ring of the bearing 25. The bearing 25 is a rolling bearing 25. The diameter of the nut 24 is equal to the diameter of the inner ring. The outer wall of the support rod 21 is provided with an external thread matching the nut 24. Through thread cooperation, the bearing 25 with the nut 24 fixedly connected to the inner ring is sleeved on the support rod 21. The end points of the floor drain tray 22 are movably connected to the outer wall of the bearing 25. There are at least 3 end points of the floor drain tray 22, and each end point of the floor drain tray 22 is connected to the outer wall of a bearing 25.

[0036] The term "relative position" in this article includes the relative position in the vertical direction and the relative angle in the horizontal direction. In the present application, the rising and falling of the floor drain tray 22 are realized by rotating the nut 24. By adjusting the heights of the end points of different floor drain trays 22, the inclination angle of the floor drain tray 22 can be adjusted. In this way, the problems of angle leveling and support of floor drains of different sizes are solved. The floor drain tray 22 and the adjusting member 23 cooperate to achieve the following two functions. One is to keep the floor drain in a horizontal position through angle adjustment, ensure that their relative positions are fixed during installation, do not rotate with the pipeline, and prevent loosening at the connection and resulting in water seepage. The other is to support floor drains of different sizes by adjusting the position of the floor drain tray 22 up and down, prevent the connection part between the pipeline and the floor drain from being easily loosened after long-term use when it is suspended, and reduce the probability of water seepage.

[0037] Furthermore, the end points of the floor drain tray 22 are hinged to the outer wall of the bearing 25. Specifically, the hinge model for hinging can be the K7-200 type hinge, so that the floor drain tray 22 can realize the angle adjustment function.

[0038] Further, the floor drain tray 22 is a triangular supporting piece. Specifically, the triangular supporting piece is an equilateral triangular supporting piece. As is known to those skilled in the art, three points can determine a plane. To save adjustment steps, the endpoints of the floor drain tray 22 in this application are selected as three points. And to maintain the consistency of each adjustment method, the triangular supporting piece is set as an equilateral triangular supporting piece.

[0039] Further, since visual observation has errors, a scale 27 is provided on the support rod 21, which can measure the positions of the endpoints of the floor drain tray 22 to ensure the balance of the floor drain tray 22.

[0040] In addition, to better support the floor drain, the support rod 21 is a telescopic rod, which is used to adjust the overall height of the same - floor drainage floor drain support. When the overhead height of the pipeline is too high, the height of the support rod 21 can be lengthened to make the same - floor drainage floor drain support touch the ground and provide support for the floor drain and the suspended pipeline. Similarly, when the overhead height of the pipeline is too low, the height of the support rod 21 can be shortened. Specifically, the telescopic rod includes an inner rod 211 and an outer rod 212 sleeved on the outer wall of the inner rod 211. The inner rod 211 is thread - connected to the outer rod 212, and the inner rod 211 moves linearly by means of screw rotation, being retracted into or extended out of the outer rod 212.

[0041] Further, a base 26 is provided at the end of the support rod 21, making the supporting effect of the same - floor drainage floor drain support more stable.

[0042] On the basis that the floor drain is supported and leveled, after being connected to the pipeline, although it can prevent the loosening of the connection between the floor drain and the pipeline caused by vibration during drainage, since the support rod 21 is a telescopic rod, that is, there is a relative displacement between the inner rod 211 and the outer rod 212 after long - term use. Therefore, a fastener 3 for stopping the inner rod 211 is provided on the outer rod 212.

[0043] Specifically, the fastener 3 includes a hoop 31 and a stop rod 32 fixedly connected to the end face of the hoop 31. Two points on the end face of the hoop 31 are selected as fixed points, and the two ends of the stop rod 32 are respectively fixedly connected to the two fixed points on the end face of the hoop 31. Further, the length of the stop rod 32 is the diameter of the end face of the hoop 31. The support rod 21 is provided with two slits 33, and the two slits 33 are connected radially, dividing the support rod 21 into two equal parts. The stop rod 32 radially penetrates through the slits 33 at the same time. After the support rod 21 is adjusted to the target height, the hoop 31 is tightened. Since the stop rod 32 stops the inner rod 211 in the longitudinal direction, it can prevent the displacement between the inner rod 211 and the outer rod 212 after long - term use.

[0044] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
