Abstract

A toilet seat that lifts up automatically. It is in the toothed housing, and the toilet seat rotating shaft, the torsion spring and the cylindrical toothed knob are sequentially connected. After the toilet seat is lifted, the cylindrical toothed knob is pushed in, the concave part on the edge of the cylindrical toothed knob is engaged with the protruding part on the edge of the housing, and the cylindrical toothed knob and the toothed housing are fixed together and cannot rotate freely. When the toilet seat is pressed, the torsion spring stores energy, and when the user leaves the toilet seat, the torsion spring will automatically lift the toilet seat. When the cylindrical-toothed knob is pushed in at different rotation angles, the speed at which the toilet seat is automatically lifted will be different. When the cylindrical-toothed knob is pulled out, the cylindrical-toothed knob will rotate freely with the torsion spring, and the torsion spring cannot store energy. At this time, the toilet seat cannot be lifted automatically, and the function is the same as that of an ordinary toilet seat.

Description

Automatic lift toilet seat

Technical field

The utility model relates to a toilet seat device, which can be lifted up automatically according to the needs of users.

Background technique

At present, the known toilet seat device structure is made up of a toilet seat, a fixed toilet cover and a bracket for the toilet seat. Lifting or putting down of the toilet seat is directly operated by human hands. When the male user urinates, the toilet seat must be in a lifted state, otherwise the toilet seat will be contaminated. In daily life, it often happens that the toilet seat is not lifted when the male user urinates, especially in public places, so that the toilet seat is polluted.

Application number is 95200892.0, and publication number is that the patent of CN2221373 also has similar function, but this device structure is relatively complicated, and aesthetic property is not good enough, and cost is higher.

Contents of the invention

In order to overcome that the existing toilet seat is easily polluted by male users when urinating, the utility model provides a toilet seat device, which can automatically lift the toilet seat when the user's buttocks leave. And the automatic lifting function can be canceled according to user needs.

The technical solution adopted by the utility model to solve the technical problem is: in the toothed housing above the bracket, the toilet seat rotating shaft, the torsion spring and the cylindrical toothed knob are sequentially connected, and after the toilet seat is lifted, the cylindrical toothed The knob is pushed into the toothed housing, and the recessed part of the edge of the cylindrical toothed knob is tightly meshed with the protruding part of the edge of the toothed housing. At this time, the cylindrical toothed knob and the toothed housing are fixed together and cannot rotate freely. , because one end of the torsion spring is fixed with the cylindrical tooth knob, and the other end is fixed with the toilet seat shaft, at this time, if the toilet seat is pressed, the torsion spring will store energy, and when the user's buttocks leave the toilet seat After the lap, the torsion spring will automatically lift the toilet seat. The cylinder-toothed knob is pushed in with different rotation angles, and the torsion spring has different torsion forces, and the speed at which the toilet seat is lifted is different. If the user pulls out the cylindrical-toothed knob, the cylindrical-toothed knob and the torsion spring will freely rotate together with the rotation of the toilet seat rotating shaft. At this time, the toilet seat cannot be lifted automatically, and the function is the same as that of a common toilet seat.

The beneficial effect of the utility model is that when the toilet seat has an automatic lifting function, the user does not need to lift the toilet seat by hand, the toilet seat will not be polluted when the male user urinates, and people can cancel it according to actual needs. Automatic lift function.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is a longitudinal sectional structure diagram of the utility model when it can be lifted up automatically.

Fig. 2 is a partial cross-sectional view of A-A of Fig. 1 of the present application.

Fig. 3 is a partial sectional view of B-B in Fig. 1 of the present utility model.

In the figure: 1. Toilet seat, 2. Rotary shaft of toilet seat, 3. Toothed housing, 4. Torsion spring, 5. 1/4 arc protruding part on the cylindrical toothed knob 6. On the cylindrical toothed knob Arc-shaped protruding part, 7. Arc-shaped protruding part in the toothed housing, 8. Cylindrical tooth-shaped knob.

Detailed ways

In FIG. 1 , one end of the torsion spring 4 is fixed together with the rotating shaft 2 of the toilet seat, and the other end is fixed together with the cylindrical tooth knob 8 . After the toilet seat 1 is lifted, the cylindrical-toothed knob 8 is pushed in, and the knob 8 is pushed in at different rotation angles, and the speed at which the toilet seat is lifted will be different. The protruding parts of the edges of the toothed housing 3 are meshed together. Since the protruding part 7 of the toothed housing 3 blocks the protruding part 6 of the cylindrical toothed knob 8, the cylindrical toothed knob 8 is fixed on the toothed housing 3 and cannot Turn freely. The user can press the toilet seat 1 by hand before use, because one end of the torsion spring 4 is fixed, so after the user presses the toilet seat 1 by hand, the torsion spring 4 has stored energy, and the user's buttocks leave the toilet seat After the circle 1, the toilet seat 1 is automatically lifted by the torsion spring 4.

If the user pulls out the cylindrical-toothed knob 8, the cylindrical-toothed knob 8 can freely rotate with the torsion spring 4 within a certain range. One end of the cylindrical toothed knob 8 has a 1/4 arc 5 blocking effect, the cylindrical toothed knob 8 is not easy to be pulled out completely, and the inner arc-shaped protrusion of the tooth-shaped housing 3 7 is paired with the upper arc-shaped protrusion of the cylindrical toothed knob 8 6, the edge of the cylindrical-toothed knob 8 will not touch the edge of the toothed housing 3. At this time, no matter whether the toilet seat 1 is lifted or put down, the torsion spring 4 and the cylindrical-toothed knob 8 will follow the toilet seat. The rotating shaft 2 rotates freely together, and the toilet seat cannot be lifted automatically.

Claims (2)

1. A toilet seat that can be lifted automatically. In the toothed housing, the toilet seat shaft, torsion spring and cylindrical toothed knob are sequentially connected. It is characterized in that the toilet seat shaft and one end of the torsion spring are fixed together, and the torsion The other end of the spring is fixed together with the cylindrical tooth knob. 2. The automatically liftable toilet seat according to claim 1, characterized in that after the cylindrical toothed knob is pushed in, the concave part on the edge of the cylindrical toothed knob engages with the protruding part on the edge of the toothed housing, and the cylindrical tooth The cylindrical-toothed knob is fixed on the toothed housing, and the cylindrical-toothed knob can rotate freely with the torsion spring only after the cylindrical-toothed knob is pulled out.
