Description

Technical Field

[0001] The present application relates to the field of pre-buried floor drains, and in particular to a disposable pre-buried floor drain for drainage of construction projects and a construction method thereof. Background Art

[0002] The floor drain refers to a drainage device that connects the ground to the drainage pipe system. It is an important interface between the drainage pipe system and the indoor floor. As an important component of the drainage system in a house, its performance directly affects the quality of indoor air and is very important for odor control in the bathroom.

[0003] The one-time embedded floor drain for engineering drainage means that when pouring the building, according to the construction drawings, the floor drain is first fixed on the building base formwork at the corresponding position, and then the concrete is poured to fix the floor drain to the concrete floor slab. When the building is used, the floor drain can be used directly without subsequent installation.

[0004] However, in actual use, some floors may choose to add floor tiles for decoration. When laying floor tiles, the cement mortar and floor tiles used will increase the thickness of the floor, resulting in the height of the original pre-buried floor drain not matching the height of the floor tiles. It is necessary to cut one end of the water pipe on the original floor drain for lengthening construction or directly make a new floor drain, which makes it more troublesome to modify the pre-buried floor drain during use. Summary of the invention

[0005] The purpose of the present application is to solve the problem that some floors mentioned in the above background technology may choose to add floor tiles for decoration. When laying the floor tiles, the cement mortar and floor tiles used will increase the thickness of the floor, resulting in the height of the original pre-buried floor drain not matching the height of the floor tiles. It is necessary to cut one end of the water pipe on the original floor drain for lengthening construction or directly make a new floor drain, which makes the pre-buried floor drain more troublesome to modify when in use. The present application provides a disposable pre-buried floor drain for construction engineering drainage and a construction method thereof.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions: A disposable pre-buried floor drain for drainage in construction engineering comprises a fixing seat, a drainage pipe is fixed on the fixing seat, a floor drain head is arranged on the drainage pipe, a water filter plate is threadedly connected to the floor drain head, a telescopic adjustment mechanism is arranged between the floor drain head and the drainage pipe, and an auxiliary limiting mechanism is arranged between the drainage pipe and the floor drain head.

[0007] By adopting the above technical solution, when secondary construction of the floor slab is required, such as laying cement mortar to fix floor tiles, the telescopic adjustment mechanism can be directly used to drive the floor drain head to adjust the height so that the floor drain head corresponds to the height of the laid cement mortar. When the telescopic adjustment mechanism is used to adjust the floor drain head and then lock it, the telescopic adjustment mechanism drives the auxiliary limiting mechanism, and the auxiliary limiting mechanism further limits and fixes the telescopic adjustment mechanism, thereby facilitating the adjustment of the height of the floor drain head and reducing the trouble of adding an extension pipe for modification or reinstalling the floor drain in subsequent construction.

[0008] Furthermore, the telescopic adjustment mechanism includes a telescopic tube fixed on the floor drain head, the leakage pipe is sleeved on the telescopic tube, two symmetrical sliding rails are fixed on the inner wall of the leakage pipe, and a sliding groove corresponding to the sliding rail is opened on the outer wall of the telescopic tube.

[0009] By adopting the above technical solution, the floor drain head is directly pulled to drive the telescopic tube, and the telescopic rod is allowed to slide on the sliding rail under the restriction of the sliding groove, so that the telescopic tube slides on the leakage pipe, and then the temporary clamping component is used to keep it stable with the leakage pipe. After the construction is completed, the locking component is directly used to limit the temporary clamping component, so that the height of the floor drain head can be changed according to the subsequent construction after the floor slab is poured, reducing the trouble of subsequent modification of the floor drain construction.

[0010] Furthermore, the temporary clamping assembly includes two clamping blocks symmetrically and slidably connected to the telescopic tube, the clamping blocks are provided with evenly distributed clamping teeth 1, the sliding rail is provided with evenly distributed clamping teeth 2, and a resistance spring is arranged between the clamping block and the telescopic tube, and both ends of the resistance spring are fixedly connected to the clamping block and the telescopic tube.

[0011] By adopting the above technical solution, the telescopic tube drives the clamping block, and the clamping tooth 1 on the clamping block slides in contact with the inclined surface of the clamping tooth 2 on the sliding rail. When the telescopic tube stops moving, the clamping tooth 1 on the clamping block is pushed by the contact spring to engage with the clamping tooth 2 on the sliding rail, so that the height of the floor drain head can be adjusted again in subsequent construction, and subsequent fixation is also convenient.

[0012] Furthermore, the locking assembly includes a support ring arranged in the telescopic tube, two symmetrical connecting blocks are fixed on the support ring, the connecting blocks are fixedly connected to the telescopic tube, two symmetrical movable rods are slidably connected to the support ring, the movable rods pass through the telescopic tube and are fixedly connected to the clamping blocks, an elliptical cylinder is arranged inside the support ring, and a rotating fixing piece is arranged between the support ring and the elliptical cylinder.

[0013] By adopting the above technical solution, the elliptical cylinder is directly driven by the rotating fixing part, and the long diameter end of the elliptical cylinder directly contacts the movable rod, so that the movable rod contacts the clamping block, and the clamping tooth 1 on the clamping block is engaged with the clamping tooth 2 on the sliding rail, so that the telescopic rod can no longer move on the drain pipe, so that after the floor drain head is adjusted, the telescopic rod can be fixed to the drain pipe to complete the adjustment of the height of the floor drain head.

[0014] Furthermore, the rotating fixing member includes a threaded ring arranged on the support ring, two symmetrical fixing blocks are fixed on the threaded ring, the fixing blocks are fixedly connected to the support ring, the threaded ring is threadedly connected with threaded blocks, and the threaded blocks are fixedly connected to the elliptical cylinder.

[0015] By adopting the above technical solution, the threaded block is allowed to rotate in the threaded ring. When the threaded block rotates, the elliptical cylinder is driven. The elliptical cylinder moves and rotates along with the threaded block, so that the end of the long diameter of the elliptical cylinder abuts against the movable rod, thereby enabling the elliptical cylinder to rotate stably, making it easier for the elliptical cylinder to abut against the movable rod, and reducing the possibility of the elliptical cylinder rotating at will.

[0016] Furthermore, a sliding rod 1 is fixed on the threaded block, an external spline is fixed on one side wall of the sliding rod, a sliding rod 2 is slidably connected to the sliding rod 1, a knob is fixed on the end of the sliding rod 2 away from the sliding rod 1, and the knob is rotatably connected to the water filter plate.

[0017] By adopting the above technical solution, the knob is turned to drive the sliding rods 1 and 2 to rotate, and the sliding rod 2 drives the threaded block to rotate, so that the threaded block can be easily rotated, and the threaded block drives the elliptical column, so that the end of the elliptical column contacts the movable rod.

[0018] Furthermore, the auxiliary limiting mechanism includes two connecting rods symmetrically fixed at the two ends of the long diameter of the elliptical cylinder, and a snap-in plate is fixed on the connecting rod. The snap-in plate is arc-shaped, and a movable groove is provided on the inner wall of the support ring. The snap-in plate is located in the movable groove and is slidably connected to the support ring. A snap-in groove is provided on the side of the movable rod, and corresponds to the snap-in plate.

[0019] By adopting the above technical solution, the elliptical cylinder drives the connecting rod, the connecting rod drives the snap-in piece, and the snap-in piece slides in the movable groove of the support ring. When the long diameter end of the elliptical cylinder abuts against one end of the movable rod, the elliptical cylinder drives the snap-in piece to be clamped in the snap-in groove on the movable rod, thereby further restricting the movable rod, improving the stability of the snap-in block abutting against the sliding rail, and improving the fixing stability between the telescopic rod and the leaking pipe.

[0020] A one-time pre-buried floor drain construction method for drainage in a construction project, the construction method comprising: S1: When you need to install a floor drain, first prepare the floor drain and fixing tools, then make a defense line on the building bottom formwork according to the design to determine the installation position of the floor drain; S2: Then put the floor drain in the corresponding predetermined position, let the fixing seat on the floor drain contact the building bottom form, and then use the fixing round nails to fix the fixing seat and the building bottom form together; S3: Then pouring is carried out. After the building pouring is completed, the building drain plate is maintained until it meets the performance requirements. Then the bottom form is removed, and a fixed drainage pipe is installed under the drain pipe. Above the drain plate, when a waterproof layer needs to be made on the floor slab and then cement mortar is used to lay tiles, the floor drain head is directly pulled to allow the floor drain head to drive the telescopic pipe to move in the drain pipe, so that the floor drain head corresponds to the thickness of the laid cement mortar; S4: Then use the clamping block on the telescopic tube to directly clamp it on the sliding rail on the drain pipe to fix it, so as to complete the height adjustment of the floor drain head, and then turn the knob to lock the clamping block with the elliptical column to complete the installation and use of the floor drain.

[0021] In summary, the present application includes at least one of the following beneficial effects: 1. The present application directly pulls the floor drain head when it is necessary to carry out secondary construction on the floor slab to lay cement mortar and floor tiles, so that the floor drain head drives the telescopic tube, and the telescopic rod slides on the sliding rail under the restriction of the sliding groove, and the telescopic tube drives the clamping block, and the clamping tooth 1 on the clamping block contacts the inclined surface on the clamping tooth 2 on the sliding rail when sliding, and the clamping block slides on the telescopic tube, and then the clamping block squeezes the contact spring, and when the telescopic tube stops moving, the clamping tooth 1 on the clamping block is pushed by the contact spring to mesh with the clamping tooth 2 on the sliding rail, so that the clamping block contacts the telescopic tube and the telescopic tube. The clamping block on the shrink tube is used for temporary support, and then construction is carried out around the floor drain head. After the construction is completed and the height of the floor drain head is determined, the threaded block is rotated in the threaded ring. The threaded block drives the elliptical column when rotating. The elliptical column moves and rotates with the threaded block, so that the end of the long diameter of the elliptical column is in contact with the movable rod, and the movable rod is used to limit the clamping block, so that the clamping tooth 1 on the clamping block and the clamping tooth 2 on the sliding rail are locked, thereby achieving the purpose of being able to conveniently adjust the height of the floor drain head and reducing the trouble of adding an extension pipe for modification or reinstalling the floor drain in subsequent construction.

[0022] 2. In the present application, while the threaded block drives the elliptical cylinder to rotate, the elliptical cylinder drives the connecting rod, the connecting rod drives the snap-in plate, and the snap-in plate slides in the movable groove of the support ring. When the long diameter end of the elliptical cylinder abuts against one end of the movable rod, the elliptical cylinder drives the snap-in plate to be stuck in the snap-in groove on the movable rod, so that the snap-in plate further restricts the movable rod, thereby achieving the purpose of further restricting the movable rod, improving the stability of the snap-in block abutting against the sliding rail, and improving the fixing stability between the telescopic rod and the leaking pipe.

[0023] 3. In the present application, when the threaded block needs to be rotated, the knob is directly rotated to allow the knob to drive the sliding rod 2 to rotate, the sliding rod 2 drives the sliding rod 1 to rotate, and the sliding rod 1 drives the threaded block to rotate, thereby achieving the purpose of facilitating the rotation of the threaded block, allowing the threaded block to drive the elliptical cylinder, and allowing the end of the elliptical cylinder to resist the movable rod.

[0026] The following is combined with Figure 1-6 This application is described in further detail.

[0027] The embodiment of the present application discloses a one-time pre-buried floor drain for drainage of a construction project and a construction method thereof.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A disposable pre-buried floor drain for drainage in construction projects comprises a fixing seat 1, a leakage pipe 2 is fixed on the fixing seat 1, a floor drain head 3 is arranged on the leakage pipe 2, a water filter plate 4 is threadedly connected to the floor drain head 3, a telescopic adjustment mechanism 5 is arranged between the floor drain head 3 and the leakage pipe 2, and an auxiliary limiting mechanism 6 is arranged between the leakage pipe 2 and the floor drain head 3.

[0029] When installing the floor drain, first place the entire floor drain at the corresponding position on the bottom form of the drain plate, let the fixing seat 1 contact the bottom form, let the fixing seat 1 restrict and fix the leakage pipe 2, then directly cast the floor slab, let the leakage pipe 2 be fixed on the floor slab, when it is necessary to perform secondary construction on the floor slab, such as laying cement mortar to fix floor tiles, the telescopic adjustment mechanism 5 can be directly used to drive the floor drain head 3 to adjust the height, so that the floor drain head 3 corresponds to the height of the laid cement mortar, and when the telescopic adjustment mechanism 5 is used to adjust the floor drain head 3 and then locked, the telescopic adjustment mechanism 5 drives the auxiliary restriction mechanism 6, and the auxiliary restriction mechanism 6 The telescopic adjustment mechanism 5 is further restricted and fixed, so that after the telescopic adjustment mechanism 5 drives the floor drain head 3 to be adjusted, the stability is further improved, and the possibility of movement of the floor drain head 3 during construction is reduced. After the drainage pipe 2 is poured in the floor slab, when the floor slab needs to be reconstructed to increase cement mortar and lay floor tiles, the telescopic adjustment mechanism 5 is used to drive the floor drain head 3, so that the height of the floor drain head 3 is adjusted with the height of the cement mortar and the floor tiles, thereby making it convenient to adjust the height of the floor drain head 3, reducing the need to add an extension pipe for modification or the trouble of reinstalling the floor drain in subsequent construction.

[0030] Reference Figure 2 , Figure 4 and Figure 5 The telescopic adjustment mechanism 5 includes a telescopic tube 51 fixed on the floor drain head 3, the leakage pipe 2 is sleeved on the telescopic tube 51, two symmetrical sliding rails 52 are fixed on the inner wall of the leakage pipe 2, and a sliding groove 53 corresponding to the sliding rail 52 is opened on the outer wall of the telescopic tube 51. A temporary clamping component 54 is arranged between the telescopic tube 51 and the leakage pipe 2, and a locking component 55 is arranged in the telescopic tube 51.

[0031] When it is necessary to adjust the height of the floor drain head 3, first determine the thickness of the cement mortar and floor tiles to be added later, then directly pull the floor drain head 3 to let the floor drain head 3 drive the telescopic tube 51, let the telescopic rod slide on the sliding rail 52 under the restriction of the sliding groove 53, let the telescopic tube 51 slide on the leakage pipe 2, and when the height of the floor drain head 3 is appropriate, directly release the floor drain head 3, and the telescopic tube 51 is kept stable with the leakage pipe 2 under the action of the temporary clamping component 54, and then construction is carried out around the floor drain head 3. After the construction is completed and it is determined that the height of the floor drain head 3 is appropriate, directly use the locking component 55 to limit the temporary clamping component 54, so that the temporary clamping component 54 can be adjusted. When the height of the drain head 3 is appropriate, the temporary clamping assembly 54 is used to temporarily fix the telescopic tube 51 and the drain pipe 2. After the construction around the drain head 3 is completed and the height of the drain head 3 is appropriate, the locking assembly 55 is used to limit the temporary clamping mechanism so that the telescopic tube 51 and the drain pipe 2 are completely fixed. This makes it convenient to change the height of the drain head 3 according to subsequent construction after the floor slab is poured, thereby reducing the trouble of subsequent modification of the floor drain construction.

[0032] Reference Figure 2 and Figure 4 The temporary clamping assembly 54 includes two clamping blocks 541 symmetrically slidably connected to the telescopic tube 51, the clamping blocks 541 are provided with uniformly distributed clamping teeth 1 542, the sliding rail 52 is provided with uniformly distributed clamping teeth 2 543, and a resistance spring 544 is provided between the clamping block 541 and the telescopic tube 51, and both ends of the resistance spring 544 are fixedly connected to the clamping block 541 and the telescopic tube 51.

[0033] When the floor drain head 3 is moved, the floor drain head 3 drives the telescopic tube 51, and the telescopic tube 51 drives the clamping block 541. When the clamping tooth 1 542 on the clamping block 541 contacts and slides with the inclined surface on the clamping tooth 2 543 on the sliding rail 52, the clamping block 541 slides on the telescopic tube 51, and then the clamping block 541 squeezes the resistance spring 544. When the telescopic tube 51 stops moving, the clamping tooth 1 542 on the clamping block 541 and the clamping tooth 2 543 on the sliding rail 52 are pushed by the resistance spring 544, so that the clamping block 541 temporarily supports the telescopic tube 51 and the clamping block 541 on the telescopic tube 51. After moving to the telescopic tube 51 and the floor drain head 3, the clamping block 541 is used for temporary fixation, so that it is convenient to adjust the height of the floor drain head 3 again in subsequent construction, and it is also convenient for subsequent fixation.

[0034] Reference Figure 2 and Figure 5The locking assembly 55 includes a support ring 551 arranged in the telescopic tube 51, and two symmetrical connecting blocks 552 are fixed on the support ring 551. The connecting blocks 552 are fixedly connected to the telescopic tube 51. Two symmetrical movable rods 553 are slidably connected to the support ring 551. The movable rods 553 penetrate the telescopic tube 51 and are fixedly connected to the clamping block 541. An elliptical cylinder 554 is arranged in the support ring 551, and a rotating fixing member 555 is arranged between the support ring 551 and the elliptical cylinder 554.

[0035] When the telescopic tube 51 moves on the leaking pipe 2, the clamping block 541 on the telescopic tube 51 moves back and forth under the action of the clamping teeth 1 542 and the clamping teeth 2 543. The clamping block 541 drives the movable rod 553 when moving. The sliding rod moves with the clamping block 541 under the support of the support ring 551. When the telescopic tube 51 and the leaking pipe 2 need to be completely fixed, the rotating fixing member 555 is directly used to drive the elliptical cylinder 554. The long diameter end of the elliptical cylinder 554 directly contacts the movable rod 553, so that the movable rod 553 can be moved. The movable rod 553 abuts against the clamping block 541, so that the clamping tooth 1 542 on the clamping block 541 is engaged with the clamping tooth 2 543 on the sliding rail 52, so that the telescopic rod can no longer move on the leakage pipe 2, and the long diameter end of the elliptical cylinder 554 is used to abut one end of the movable rod 553, so that the movable rod 553 abuts against the clamping block 541, so that the clamping block 541 cannot slide on the telescopic rod, so that after the floor drain head 3 is adjusted, the telescopic rod can be fixed to the leakage pipe 2 to complete the adjustment of the height of the floor drain head 3.

[0036] Reference Figure 2 and Figure 5 The rotating fixing member 555 includes a threaded ring 5551 arranged on the supporting ring 551, and two symmetrical fixing blocks 5553 are fixed on the threaded ring 5551. The fixing blocks 5553 are fixedly connected to the supporting ring 551. The threaded ring 5551 is threadedly connected with a threaded block 5552, and the threaded block 5552 is fixedly connected to the elliptical cylinder 554.

[0037] When it is necessary to rotate the elliptical cylinder 554, the threaded block 5552 is allowed to rotate in the threaded ring 5551. The threaded block 5552 drives the elliptical cylinder 554 when rotating. The elliptical cylinder 554 moves and rotates along with the threaded block 5552, so that the end of the long diameter of the elliptical cylinder 554 abuts against the movable rod 553, and the movable rod 553 restricts the clamping block 541. At the same time, under the restriction of the threaded rod and the threaded ring 5551, the possibility of the elliptical cylinder 554 rotating independently is reduced. By rotating the threaded block 5552 on the threaded ring 5551, the threaded block 5552 drives the elliptical cylinder 554 to rotate, so that the elliptical cylinder 554 can rotate stably, which makes it convenient for the elliptical cylinder 554 to abut against the movable rod 553, and at the same time reduces the possibility of the elliptical cylinder 554 rotating at will.

[0038] Reference Figure 2 and Figure 5 A sliding rod 5554 is fixed on the threaded block 5552, an external spline is fixed on the side wall of the sliding rod 5554, a sliding rod 2 5555 is slidably connected to the sliding rod 1 5554, a knob 5556 is fixed on the end of the sliding rod 2 5555 away from the sliding rod 1 5554, and the knob 5556 is rotatably connected to the water filter plate 4.

[0039] When it is necessary to rotate the threaded block 5552, directly rotate the knob 5556 to allow the knob 5556 to drive the sliding rod 2 5555 to rotate, the sliding rod 2 5555 drives the sliding rod 1 5554 to rotate, and the sliding rod 1 5554 drives the threaded block 5552 to rotate. By directly rotating the knob 5556 on the water filter plate 4, the sliding rod 1 5554 and the sliding rod 2 5555 drive the threaded block 5552 to rotate, so that the threaded block 5552 can be easily rotated, and the threaded block 5552 can drive the elliptical cylinder 554, so that the end of the elliptical cylinder 554 can resist the movable rod 553.

[0040] Reference Figure 3 and Figure 6 The auxiliary limiting mechanism 6 includes two connecting rods 63 symmetrically fixed at the two ends of the long diameter of the elliptical cylinder 554, and a snap-in piece 61 is fixed on the connecting rod 63. The snap-in piece 61 is arc-shaped, and a movable groove 64 is provided on the inner wall of the support ring 551. The snap-in piece 61 is located in the movable groove 64 and is slidably connected to the support ring 551. A snap-in groove 62 is provided on the side of the movable rod 553 and corresponds to the snap-in piece 61.

[0041] While the threaded block 5552 drives the elliptical cylinder 554 to rotate, the elliptical cylinder 554 drives the connecting rod 63, and the connecting rod 63 drives the snap-in piece 61. The snap-in piece 61 slides in the movable groove 64 of the support ring 551. When the long diameter end of the elliptical cylinder 554 abuts against one end of the movable rod 553, the elliptical cylinder 554 drives the snap-in piece 61 to be stuck in the snap-in groove 62 on the movable rod 553, so that the snap-in piece 61 further restricts the movable rod 553. By rotating the elliptical cylinder 554 and making the long diameter end of the elliptical cylinder 554 abut against the movable rod 553, the elliptical cylinder 554 drives the snap-in piece 61 to be stuck in the snap-in groove 62 on the movable rod 553, so that the movable rod 553 can be further restricted, thereby improving the stability of the snap-in block 541 abutting against the sliding rail 52 and improving the fixing stability between the telescopic rod and the leaking pipe 2.

[0042] A construction method for a one-time pre-buried floor drain for drainage in a construction project, which is applicable to any one-time pre-buried floor drain for drainage in a construction project, and the construction method is: S1: When you need to install a floor drain, first prepare the floor drain and fixing tools, then make a defense line on the building bottom formwork according to the design to determine the installation position of the floor drain; S2: Then put the floor drain in the corresponding predetermined position, let the fixing base 1 on the floor drain contact the building bottom form, and then use the fixing round nails to fix the fixing base 1 and the building bottom form together; S3: Then pouring is carried out. After the building pouring is completed, the building drain plate is maintained until it meets the performance requirements, and then the bottom mold is removed, and a fixed drainage pipe is installed under the drain pipe 2. Above the drain plate, when a waterproof layer needs to be made on the floor slab and then cement mortar is used to lay tiles, the floor drain head 3 is directly pulled to allow the floor drain head 3 to drive the telescopic pipe 51 to move in the drain pipe 2, so that the floor drain head 3 corresponds to the thickness of the laid cement mortar; S4: Then use the clamping block 541 on the telescopic tube 51 to directly clamp on the sliding rail 52 on the leakage pipe 2 to fix it, complete the height adjustment of the floor drain head 3, then turn the knob 5556, use the elliptical cylinder 554 to lock the clamping block 541, and complete the installation and use of the floor drain.

[0043] Working principle: when installing the floor drain, first put the entire floor drain in the corresponding position on the bottom mold of the drain plate, let the fixing seat 1 contact the bottom mold, let the fixing seat 1 restrict and fix the leakage pipe 2, then directly cast the floor slab, let the leakage pipe 2 be fixed on the floor slab, when it is necessary to carry out secondary construction of the floor slab to lay cement mortar and floor tiles, first determine the thickness of the cement mortar and floor tiles added later, and then directly pull the floor drain head 3, let the floor drain head 3 drive the telescopic tube 51, let the telescopic rod slide on the sliding rail 52 under the restriction of the sliding groove 53, and the telescopic tube 51 drives the clamping block 541, and the clamping teeth on the clamping block 541 are When 542 slides in contact with the inclined surface of the second engaging tooth 543 on the sliding rail 52, the engaging block 541 slides on the telescopic tube 51, and then the engaging block 541 squeezes the resisting spring 544. When the telescopic tube 51 stops moving, the resisting spring 544 pushes the engaging tooth 1 542 on the engaging block 541 to engage with the second engaging tooth 543 on the sliding rail 52, so that the engaging block 541 temporarily supports the telescopic tube 51 and the engaging block 541 on the telescopic tube 51, and then construction is carried out around the floor drain head 3. During the construction process, when the floor drain head 3 needs to be adjusted, it can be adjusted again.

[0044] When the height of the floor drain head 3 is determined and the floor drain head 3 needs to be fixed, the knob 5556 is directly turned to make the knob 5556 drive the sliding rod 2 5555 to rotate, the sliding rod 2 5555 drives the sliding rod 1 5554 to rotate, the sliding rod 1 5554 drives the threaded block 5552 to rotate, and the threaded block 5552 rotates in the threaded ring 5551. When the threaded block 5552 rotates, it drives the elliptical column 554, and the elliptical column 554 moves and rotates with the threaded block 5552, so that the end of the long diameter of the elliptical column 554 contacts the movable rod 553, and the movable rod 553 contacts the clamping block 541. The clamping teeth 1 542 on the clamping block 541 and the clamping teeth 2 543 on the sliding rail 52 are restricted so that the threaded block 5552 drives the elliptical cylinder 554 to rotate. At the same time, the elliptical cylinder 554 drives the connecting rod 63, and the connecting rod 63 drives the clamping piece 61. The clamping piece 61 slides in the movable groove 64 of the support ring 551. When the long diameter end of the elliptical cylinder 554 abuts against one end of the movable rod 553, the elliptical cylinder 554 drives the clamping piece 61 to be stuck in the clamping groove 62 on the movable rod 553, so that the clamping piece 61 further restricts the movable rod 553, and the construction and installation of the floor drain is completed.
