Description

Technical Field

[0001] The utility model relates to the field of toilets, in particular to a pipeline sealing component. Background Art

[0002] Nowadays, straight-flush toilets have gradually replaced siphonic toilets. The advantage of straight-flush toilets over siphonic toilets is that a sealing disk that rotates and fits on the step surface of the pipe is used to replace the water trap of the traditional siphonic toilet. The sealing disk is used to store water and prevent odor. At the same time, compared with the winding siphonic toilet pipe, the straight-flush toilet is not prone to blockage problems because it discharges directly through a straight pipe.

[0003] However, the production technology on the market cannot guarantee that the step surface inside the pipe can be completely vertical during the production or installation of the pipe, so that it cannot fit tightly with the sealing disk, which ultimately affects the sealing effect. Utility Model Content

[0004] The utility model provides a pipeline sealing component structure, which has the effect of ensuring that a step surface in a pipeline and a sealing disk are closely fitted.

[0005] The utility model provides a pipeline sealing assembly adopting the following technical solution:

[0006] A pipeline sealing assembly, characterized in that it includes a sealing disk, a rotating plate, a mounting frame and a mounting disk, wherein the mounting frame is hinged on the rotating plate and can swing left and right relative to the rotating plate, the mounting disk is hinged on the mounting frame and can swing back and forth relative to the mounting frame, and the sealing disk is fixed on the mounting disk.

[0007] Through the above technical solution, the hinged relationship between the mounting frame, the mounting plate and the rotating plate is utilized to adjust the sealing plate in the front-to-back and left-to-right directions so that it fits tightly with the stepped surface of the pipeline to form a more effective seal.

[0008] Preferably, it also includes a first hinge rod, the front end of the rotating plate has a hinge plate, the hinge plate is provided with two mounting grooves which are adjacent to each other in the front and rear direction, the first hinge rod is fixedly inserted in the two mounting grooves along the front and rear direction, and two first hinge seats are provided on the mounting frame, and the two first hinge seats extend into the two mounting grooves one by one and are sleeved with the first hinge rod.

[0009] Through the above technical solution, the mounting frame can swing left and right relative to the rotating plate on the hinge plate through the hinge relationship between the first hinge seat and the first hinge rod.

[0010] Preferably, the hinged plate is L-shaped as a whole, and forms an accommodating space for accommodating the mounting bracket between the hinged plate and the front end of the rotating plate.

[0011] Through the above technical solution, the accommodating space formed by the L-shaped hinged plate enables the side of the sealing disk connected to the rotating plate and the mounting frame facing the step surface to be located on the same plane and can be directly attached to the step surface; if there is no hinged plate, the design of the mounting frame will inevitably make the sealing disk protrude toward the step surface, and the step surface will inevitably be provided with a recess inward in order to cooperate with the sealing disk and the rotating plate. Such rotation effect is like inserting the sealing disk into the step surface, which easily causes friction between the side wall of the sealing disk and the step surface; driving the sealing disk to swing, affecting the subsequent sealing effect.

[0012] Preferably, it further includes a second hinged rod, the mounting frame is provided with two matching grooves which are spaced apart from each other on the left and right sides, the second hinged rod is fixedly inserted in the two matching grooves along the left and right directions, and the mounting plate is provided with two second hinged seats, the two second hinged seats extend into the two matching grooves one by one and are sleeved with the second hinged rod.

[0013] Through the above technical solution, the mounting plate can swing back and forth relative to the rotating plate on the mounting frame through the hinged relationship between the second hinged seat and the second hinged rod.

[0014] Preferably, installation shafts are fixedly provided on both left and right sides of the rear end of the rotating plate, and two installation seats are fixedly sleeved on the installation shafts.

[0015] Through the above technical solution, the design of the mounting shaft and the mounting seat provides a stable rotation platform for the rotating plate, thereby making the rotation process of the rotating plate more stable.

[0016] Preferably, it further comprises a driving source, the output end of the driving source is connected to the installation shaft through a transmission assembly so as to be able to drive the installation shaft to rotate.

[0017] Through the above technical solution, when flushing is required, the driving source drives the installation shaft to rotate through the transmission assembly, thereby driving the rotating plate to rotate and open the pipe; after flushing is completed, the driving source drives the rotating plate to return to the step surface.

[0018] Preferably, a protrusion is further included, wherein the protrusion is arranged on the mounting plate and is located directly below the second hinge rod, and an arc groove which is interference-fitted with the second hinge rod is formed on the top of the protrusion.

[0019] Through the above technical solution, the contact area and friction between the sealing plate and the second hinged rod are increased by the interference fit between the protrusion and the second hinged rod, thereby reducing the situation in which the sealing plate loses its sealing effect due to the pressure of the stored water on the bottom after water storage during long-term use.

[0020] Preferably, the bottom of the mounting frame has a receiving groove for receiving the protrusion.

[0021] Through the above technical solution, the accommodating groove enables the mounting frame to cooperate with the mounting plate with the protrusion, thereby achieving stable connection and assembly.

[0022] The technical effects of this utility model are mainly reflected in the following aspects:

[0023] 1. The utility model provides a mounting frame and a mounting plate, thereby adjusting the sealing plate in the front-to-back and left-to-right directions, so that it fits closely with the stepped surface of the pipeline to form a more effective seal;

[0024] 2. The utility model provides a storage space so that the side of the sealing disk connected to the rotating plate and the mounting frame facing the step surface is located on the same plane;

[0025] 3. The utility model provides the protrusions to reduce the situation in which, during long-term use, the sealing disc is pressed against the step surface and water is stored, and the pressure of the stored water on the bottom of the sealing disc pushes the sealing disc away, causing it to lose its sealing effect.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0031] The utility model discloses a pipeline sealing assembly:

[0032] Reference Figure 1-3A pipeline sealing assembly includes a sealing disc 1, a rotating plate 2, a mounting frame 3 and a mounting disc 4. The mounting frame 3 is hinged on the rotating plate 2 and can swing left and right relative to the rotating plate 2. The mounting disc 4 is hinged on the mounting frame 3 and can swing forward and backward relative to the mounting frame 3. The sealing disc 1 is fixed on the mounting disc 4. By utilizing the hinged relationship between the mounting frame 3, the mounting disc 4 and the rotating plate 2, the sealing disc 1 can be adjusted in the front-back and left-right directions so that it fits tightly with the step surface 101 of the pipeline 10 to form a more effective seal.

[0033] Reference Figure 2 , and further comprises a first hinge rod 5, a hinge plate 21 is provided at the front end of the rotating plate 2, two mounting grooves 211 are arranged on the hinge plate 21 and are adjacent to each other in the front and rear directions, the first hinge rod 5 is fixedly inserted in the two mounting grooves 211 along the front and rear directions, and two first hinge seats 31 are arranged on the mounting frame 3, and the two first hinge seats 31 are inserted into the two mounting grooves 211 one by one and are sleeved with the first hinge rod 5. The mounting frame 3 can swing left and right relative to the rotating plate 2 on the hinge plate 21 through the hinged relationship between the first hinge seat 31 and the first hinge rod 5.

[0034] It also includes a second hinge rod 6. The mounting frame 3 is provided with two matching grooves 32 spaced apart from each other. The second hinge rod 6 is fixedly inserted into the two matching grooves 32 along the left-right direction. The mounting plate 4 is provided with two second hinge seats 41. The two second hinge seats 41 extend into the two matching grooves 32 one by one and are sleeved with the second hinge rod 6. The mounting plate 4 can swing forward and backward relative to the rotating plate 2 on the mounting frame 3 through the hinge relationship between the second hinge seat 41 and the second hinge rod 6. And the mounting plate 4 can swing left and right relative to the rotating plate 2 through the hinge relationship between the mounting frame 3 and the mounting frame 3.

[0035] Reference Figure 1-2 The hinge plate 21 is L-shaped as a whole, and forms a receiving space 212 for receiving the mounting frame 3 between the hinge plate 2 and the front end of the rotating plate 2. The receiving space 212 formed by the L-shaped hinge plate 21 makes the side of the sealing disc 1 connected to the rotating plate 2 and the mounting frame 3 facing the step surface 101 be located on the same plane, and can be directly attached to the step surface 101; if there is no hinge plate 21, the design of the mounting frame 3 must make the sealing disc 1 protrude toward the step surface 101, and the step surface 101 must be recessed inwardly to match the sealing disc 1 and the rotating plate 2. Such a rotation effect is like inserting the sealing disc 1 into the step surface 101, which easily causes the side wall of the sealing disc 1 to rub against the step surface 101; driving the sealing disc 1 to swing, affecting the subsequent sealing effect.

[0036] Reference Figure 1-2The left and right sides of the rear end of the rotating plate 2 are fixedly provided with mounting shafts 7, and two mounting seats 8 are fixedly sleeved on the mounting shafts 7. The design of the mounting shafts 7 and the mounting seats 8 provides a stable rotating platform for the rotating plate 2, thereby making the rotating process of the rotating plate 2 more stable.

[0037] Reference Figure 3 , and also includes a driving source 9, the output end of which is connected to the installation shaft 7 through a transmission assembly 91, so as to be able to drive the installation shaft 7 to rotate. When flushing is required, the driving source 9 drives the installation shaft 7 to rotate through the transmission assembly 91, thereby driving the rotating plate 2 to rotate and open the pipe 10; after flushing is completed, the driving source 9 drives the rotating plate 2 to reset and fit on the step surface 101. The driving source 9 can be a motor, etc. The transmission assembly 91 can include a telescopic rod, a rotating wrench and a rotating shaft, one end of the rotating shaft is connected to the installation shaft 7, and the other end is connected to the rotating wrench. The telescopic rod moves on the motor in a vertical direction and is used to drive the rotating wrench to rotate. The rotating wrench drives the rotating shaft to rotate, thereby rotating the installation shaft 7 and finally driving the rotating plate 2 to rotate.

[0038] Reference Figure 2 , and further includes a protrusion 42, which is arranged on the mounting plate 4 and is located directly below the second hinge rod 6, and an arc groove 421 is provided on the top of the protrusion 42 for interference fit with the second hinge rod 6. The contact area and friction between the sealing plate and the second hinge rod 6 are increased by the interference fit between the protrusion 42 and the second hinge rod 6, thereby reducing the situation in which the sealing plate loses its sealing effect due to the pressure of the stored water at the bottom after water storage in long-term use. At the same time, the bottom of the mounting frame 3 has a receiving groove 33 for accommodating the protrusion 42. The receiving groove 33 enables the mounting frame 3 to cooperate with the mounting plate 4 having the protrusion 42, thereby achieving stable connection and assembly.

[0039] Reference Figure 1-2 The sealing disc 1 is covered with a sealing rubber sleeve 11. Since the sealing rubber sleeve 11 has good elasticity and sealing performance, it can further enhance the fitting effect between the sealing disc 1 and the step surface 101, thereby effectively preventing water, gas or odor from leaking from the gap.
