Abstract

A foldable screen and a shower room are provided. The foldable screen includes a transmission gear mechanism and a plurality of panel bodies arranged in sequence. End portions of two adjacent sides of two adjacent panel bodies enclose to form a mounting opening into which the transmission gear mechanism is installed for realizing folding and unfolding of the plurality of panel bodies. The transmission gear mechanism includes a housing having a receiving cavity therein, the housing being installed in the mounting opening; a first gear located in the receiving cavity and installed on one of the two adjacent panel bodies; and a second gear meshed with the first gear, the second gear being located in the receiving cavity and installed on the other of the two adjacent panel bodies.

First claim

What we claim is:

1. A foldable screen, comprising a transmission gear mechanism and a plurality of panel bodies arranged in sequence, wherein end portions of two adjacent sides of two adjacent panel bodies of the plurality of panel bodies enclose to form a mounting opening into which the transmission gear mechanism is installed for realizing folding and unfolding of the plurality of panel bodies;
wherein the transmission gear mechanism comprises:
a housing having a receiving cavity therein, the housing being installed in the mounting opening;
a first gear located in the receiving cavity and installed on one of the two adjacent panel bodies; and
a second gear meshed with the first gear, the second gear being located in the receiving cavity and installed on the other of the two adjacent panel bodies;
wherein the housing is provided on an outer top surface of an inner end thereof with a water storage groove, and the housing is provided on the outer side surface thereof with a water outlet which is communicated with the water storage groove.

2. The foldable screen according to claim 1 , wherein an outer side surface of an inner end of the housing is provided with a guiding portion.

3. The foldable screen according to claim 2 , wherein any one of the two adjacent panel bodies comprises:
a frame provided with notches at the outer frame corners of the frame, the notches of the frame and an adjacent frame of the frame facing each other and enclosing to form the mounting opening; and
a baffle installed in the frame;
wherein the frame comprises two vertical frame parts, two horizontal frame parts, and four connectors connecting the two vertical frame parts and the two horizontal frame parts together, and the notches are positioned on the connectors.

4. The foldable screen according to claim 1 , wherein one of an end face of an inner end of the housing and a top wall of the mounting opening is provided with an annular water stop rib, and the other is provided with an annular water stop groove into which the water stop rib is inserted.

5. The foldable screen according to claim 1 , wherein the housing is a closed housing or an open-ended housing.

6. The foldable screen according to claim 1 , further comprising at least one of the following:
a first seal disposed between the two adjacent panel bodies;
a second seal disposed on end faces of the plurality of panel bodies along the folding and unfolding directions of the foldable screen with an outer end of the housing abutting on the second seal.

7. The foldable screen according to claim 1 , wherein any one of the two adjacent panel bodies comprises:
a frame provided with notches at the outer frame corners of the frame, the notches of the frame and an adjacent frame of the frame facing each other and enclosing to form the mounting opening; and
a baffle installed in the frame;
wherein the frame comprises two vertical frame parts, two horizontal frame parts, and four connectors connecting the two vertical frame parts and the two horizontal frame parts together, and the notches are positioned on the connectors.

8. The foldable screen according to claim 7 , wherein each of the connectors is L-shaped and comprises a horizontal edge and a vertical edge, wherein the horizontal edge is connected with a vertical frame part of the frame, and the vertical edge is connected with a horizontal frame part of the frame.

9. The foldable screen according to claim 8 , wherein the side surface of the housing contacting the connector is convex to match with the housing, and the vertical edge of the connector is concave to match with the housing.

10. The foldable screen according to claim 9 , further comprising a seal between the housing and the connector.

11. The foldable screen according to claim 9 , wherein a screw hole is provided on the horizontal edge of the connector for connecting the horizontal edge with the vertical frame part of the frame by a screw.

12. A shower room comprising a foldable screen as claimed in claim 1 .

13. A transmission gear mechanism for realizing folding and unfolding of two adjacent panel bodies, wherein end portions of two adjacent sides of the two adjacent panel bodies enclose to form a mounting opening into which the transmission gear mechanism is installed,
wherein the transmission gear mechanism comprises:
a housing having a receiving cavity therein, the housing being installed in the mounting opening;
a first gear located in the receiving cavity and installed on one of the two adjacent panel bodies; and
a second gear meshed with the first gear, the second gear being located in the receiving cavity and installed on the other of the two adjacent panel bodies;
wherein the housing is provided on an outer top surface of an inner end thereof with a water storage groove, and the housing is provided on an outer side surface thereof with a water outlet which is communicated with the water storage groove.

14. The transmission gear mechanism according to claim 13 , wherein an outer side surface of an inner end of the housing is provided with a guiding portion.

15. The transmission gear mechanism according to claim 13 , wherein one of an end face of an inner end of the housing and a top wall of the mounting opening is provided with an annular water stop rib, and the other is provided with an annular water stop groove into which the water stop rib is inserted.

16. The transmission gear mechanism according to claim 13 , wherein the housing is a closed housing or an open-ended housing.
