Abstract
Description
Technical Field
[0001] The utility model belongs to the field of sanitary ware, and particularly relates to a wax-ring-free toilet drain outlet sealing component with good sealing effect, long service life, and convenient and simple installation. Background Art
[0002] The sewage outlet of the toilet is fixed to the flange during installation. In order to ensure the sealing effect, a wax ring is applied to the sewage outlet. This method of applying a wax ring can achieve a certain sealing effect, but it also has major defects. The sealing effect of the wax ring is not ideal and there will still be leakage, which results in poor user experience. The wax ring is prone to aging and failure, has a short service life, and requires frequent replacement and maintenance. The installation and replacement is troublesome and inefficient, the labor cost is high, and the labor intensity is high, which cannot meet limited usage requirements.
[0003] The technical problem to be solved by the utility model is to provide a wax-ring-free toilet drain outlet sealing component with good sealing effect, not easy to leak, good user experience, long service life, no need for frequent replacement and maintenance, simple installation and high efficiency, low labor cost, low labor intensity, and effective satisfaction of use requirements. Utility Model Content
[0004] In order to solve the problems of the above-mentioned prior art wax rings, such as unsatisfactory sealing effect, easy leakage, poor user experience, easy aging and failure of the wax ring, short service life, frequent replacement and maintenance, troublesome installation and replacement, low efficiency, high labor cost, high labor intensity, and inability to meet limited use requirements, the utility model adopts the following technical solutions:
[0005] The utility model provides a wax-ring-free toilet drain outlet sealing assembly, comprising a sealing body, the sealing body being irregular in shape and made of TPE, the sealing body comprising a connecting base plate, a supporting middle section and a docking bowl, the connecting base plate being provided with a hard steel ring and the outer ring being provided with a plurality of bolt holes, the connecting base plate being threadedly fastened to an external connecting flange by bolts passing through the bolt holes, the docking bowl being cylindrical in shape with a larger upper portion and a smaller lower portion and the top being a receiving plane, the receiving plane of the docking bowl being docked with the external toilet drain outlet and being squeezed downward to fit the inner wall of the connecting flange.
[0006] Preferably, the outer wall of the supporting middle section is provided with a plurality of circular ribs.
[0007] Preferably, the support middle section is cylindrical in shape with a smaller top and a larger bottom.
[0008] The beneficial effects of this utility model are: it uses soft rubber sealing parts made of TPE material for connection, has good sealing effect, is not easy to leak, has a good user experience, has a long service life, does not require frequent replacement and maintenance, is simple to install and has high efficiency, has low labor costs and low labor intensity, and effectively meets the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of the three-dimensional structure of an embodiment of the utility model.
[0010] Figure 2 This is a schematic diagram of the main structure of the present utility model. DETAILED DESCRIPTION
[0011] The preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0012] See also Figure 1 、 Figure 2 A wax-ring-free toilet drain outlet sealing assembly includes a sealing body 1. The sealing body 1 is irregular in shape and made of TPE. TPE is a soft gel with good elasticity. The sealing body 1 includes a connecting base plate 11, a supporting middle section 12 and a docking bowl 13. The connecting base plate 11 is equipped with a hard steel ring and the outer ring is provided with a plurality of bolt holes 14. The built-in steel ring strengthens the bottom strength, the force is more uniform, and the use effect is better. The connecting base plate 11 is threadedly fastened to the external connecting flange 2 by bolts passing through the bolt holes 14. The docking bowl 13 is cylindrical with a larger upper portion and a smaller lower portion and a receiving plane 15 on the top. The receiving plane 15 of the docking bowl 13 is docked with the external toilet drain outlet and is squeezed downward to fit the inner wall of the connecting flange, so that the sealing effect is better.
[0013] The outer wall of the supporting middle section 12 is provided with a plurality of ring ribs 16, which optimize the compression deformation and provide a better sealing effect.
[0014] The supporting middle section 12 is cylindrical in shape with a small top and a large bottom.
[0015] The beneficial effects of this utility model are: it uses soft rubber sealing parts made of TPE material for connection, has good sealing effect, is not easy to leak, has a good user experience, has a long service life, does not require frequent replacement and maintenance, is simple to install and has high efficiency, has low labor costs and low labor intensity, and effectively meets the use requirements.
[0016] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
