Description

Floor drain with adjustable pretightening force

Technical Field

The utility model relates to the technical field of parts of drainage systems, in particular to a floor drain with adjustable pretightening force.

Background

The floor drain is an important interface for connecting a drainage pipeline system with the indoor ground, is used as an important component of the drainage system in a house, has good performance, directly influences the quality of indoor air, and is very important for controlling the peculiar smell of a bathroom. The main functions of the floor drain are as follows: odor prevention, blockage prevention, cockroach prevention, virus prevention, water return prevention and drying prevention (mainly referred to as a water seal type floor drain); the floor drain is mainly checked from four angles: drainage speed, deodorization effect, easy cleaning and no mechanical principle durability.

Floor drain classification: 1. traditional water seal floor drain. 2. The eccentric block type floor drain with lower turning plate is fixed with one sealing washer and one lead block via one pin and is sealed via gravity eccentric principle. This structure is initially horizontal and later evolved to be vertical with water seals. When the water is drained, the gasket is opened under the action of water pressure, and after the water drainage is finished, the gasket is closed under the action of gravity of the lead block. 3. The spring floor drain is sealed by stretching a sealing gasket at the lower end of the sealing core by a spring. When no water or water is in the floor drain, the sealing gasket is stretched upwards by the spring to seal the pipeline, and when the water in the floor drain reaches a certain height and the gravity of the water exceeds the elasticity of the spring, the spring is pressed downwards by the water, and the sealing gasket is opened to automatically drain water. 4. The structure of the floor drain is similar to a spring type floor drain, and the floor drain is sealed by using magnetic attraction sealing gaskets of two magnets. When the water pressure is greater than the magnetic force, the sealing gasket is opened downwards to drain water, the water drainage is finished, the water pressure is reduced, and when the water pressure is less than the magnetic force, the magnet blocks are attracted, and the sealing gasket is pulled upwards. The advantages are that: the plastic core may be manufactured in different types. 5. The gravity floor drain does not need water seal, does not use external forces such as springs, magnets and the like, and automatically opens and closes the sealing cover plate by utilizing the balance relation between the gravity of water flow and floating balls in the floor drain. This mode is similar to spring type, but converts the spring force into a buoyancy force to bring about mechanical tension. 6. The silica gel floor drain is sealed by two thin silica gel sheets or silica gel bags with bottom openings. The silica gel bottom is washed away by water during the drainage, and after the drainage is finished, the silica gel bottom is laminated because of self elasticity effect and opening are automatic because of remaining moisture, realizes deodorant effect. 7. The novel water-sealed floor drain is a floor drain with long deodorizing effect in the market. The water seal floor drain is characterized in that a bell-shaped or sleeve pipe device in a water storage cavity is utilized to form an N-shaped or U-shaped water storage bend, and odor and bacteria in a drainage pipeline are isolated by means of water seal, so that the deodorizing effect is realized.

Among them, the most common are eccentric block type floor drain with lower turning plate, spring type floor drain and magnet type floor drain. The application is mainly an optimization improvement on the spring floor drain.

Referring to a floor drain example, refer to patent document CN207376773U, a floor drain sealing sewer core is disclosed, the floor drain sealing sewer core comprises a water core main body, an indent platform is arranged on the upper surface of the water core main body, mounting protrusions are arranged on two sides of the upper surface of the indent platform, a first sealing rubber pad is mounted on the inner side of the indent platform, a first mounting hole is arranged on one side surface of the mounting protrusions, a water storage pipe is mounted on the lower surface of the water core main body, a vertical plate is arranged on one side of the water storage pipe, a mounting column is arranged below the vertical plate, and a matched bayonet is mounted on the outer side of the mounting column; the water storage pipe, the water leakage flip cover and the decorative cover can be connected through the cooperation of the mounting column and the cooperation bayonet, the structure is simple, the water leakage flip cover is easy to detach and mount, the communication between the outside and the underground pipeline can be isolated, meanwhile, the situation that pests and odor cannot pass through the water leakage flip cover is avoided, the combined structure of the vertical plate, the water leakage flip cover and the elastic rubber ring occupies a small proportion of the structure relative to other products on the market, and the water drainage space is larger than the similar water cores with the same size.

The above-mentioned patent structure, which adopts the elastic rubber ring to replace the metal spring, achieves some advantages (such as cost advantage), but the applicant also finds some disadvantages through test analysis, such as: 1. the installation position of the elastic rubber ring in the existing product is fixed and unique, but the elasticity of the elastic rubber ring is unstable, so that the elastic rubber ring is excessively tightened and loosened, and the elastic force applied to the flip cover is unstable, so that good rebound and sealing effects cannot be realized; 2. after long-time use, the elastic rubber ring is tired, namely the elastic rubber ring can be loosened than when just using, and the problem that the sealing cover is not in place in a rebound mode and is not tight in sealing is easily caused at the moment, so that the deodorization effect of the floor drain is affected.
