Description

Technical Field

[0001] The utility model relates to the technical field of waterproof devices, in particular to a water overflow prevention structure at a threshold of a toilet. Background Art

[0002] The bathroom is an essential part of a residence as a space for residents to bathe and wash. For bathrooms that do not use dry and wet separation, its functional characteristics determine that water will inevitably accumulate in the bathroom space or splash onto the threshold or even splash outside the door. In general, the threshold of the bathroom is often raised to prevent water overflow.

[0003] However, if the bathroom threshold is built too high, it will easily cause obstacles and inconvenience in entering and exiting; if it is not built high enough, its role in preventing overflow and splashing is very limited. Once the bathroom overflows or splashes a lot, it may cause the bathroom water to overflow the bathroom threshold and overflow to areas outside the bathroom, causing damage to other areas due to water soaking. Therefore, the use and design of the anti-overflow structure at the bathroom threshold is particularly important. Utility Model Content

[0004] In view of the above technical problems in the related art, the utility model proposes a water overflow prevention structure at the threshold of the toilet, which can overcome the above shortcomings of the prior art.

[0005] In order to achieve the above technical purpose, the technical solution of the utility model is implemented as follows:

[0007] The anti-overflow structure at the threshold of the bathroom includes a storage box, which is preset in a grid groove in the threshold. A reel is arranged in the storage box, and a plurality of circles of water-blocking grilles are wound around the outside of the reel. Slideways connected to the two ends of the grille telescopic holes are preset in the wall surfaces of the left wall and the right wall on both sides of the threshold. The top end surface of the water-blocking grille passes through the grille telescopic hole and can be telescopically arranged under the contraction of the slideway.

[0008] Furthermore, the slide includes a left slide preset in the left wall and a right slide preset in the right wall.

[0009] Furthermore, the grille telescopic hole has the same width as the openings of the left slideway and the right slideway.

[0010] Furthermore, the height of the water-blocking grille extending out of the storage box is greater than or equal to 20 centimeters.

[0011] Furthermore, the distance between the portion of the water-blocking grille extending out of the storage box and the door panel is greater than 1 cm and less than 5 cm.

[0012] Furthermore, shrinkage limiting blocks are fixedly provided at the places where both sides of the top end surface of the water blocking grille contact the slideway, and the width of the shrinkage limiting blocks exposed from the slideway is greater than the width of the opening of the grille telescopic hole.

[0013] Furthermore, an overflow port is provided at the bottom of the storage box, and the overflow port is connected to a sewer pipe.

[0014] The beneficial effects of the utility model are as follows: by adding an anti-overflow structure at the threshold of the bathroom, the probability of overflow to the outside when there is a lot of water in the bathroom can be effectively reduced.

[0022] like Figure 1-3 As shown, according to an embodiment of the utility model, a water overflow prevention structure at a threshold of a bathroom comprises a storage box 8, wherein the storage box 8 is preset in a grid groove in the threshold 4, a reel 13 is arranged in the storage box 8, and a plurality of circles of water blocking grilles 11 are wound around the outside of the reel 13, and slideways 5 connected to the two ends of the grille telescopic hole 7 are preset in the wall surfaces of the left wall 2 and the right wall 3 on both sides of the threshold 4, and the top end surface of the water blocking grille 11 passes through the grille telescopic hole 7 and can be telescopically arranged under the contraction of the slideway 5.

[0023] In a specific embodiment, the slideway 5 includes a left slideway 9 preset in the left wall 2 and a right slideway 10 preset in the right wall 3 .

[0024] In a specific embodiment, the grille telescopic hole 7 and the openings of the left slideway 9 and the right slideway 10 are all the same in width.

[0025] In a specific embodiment, the height of the portion of the water blocking grille 11 extending out of the storage box 8 is greater than or equal to 20 centimeters.

[0026] In a specific embodiment, the distance between the portion of the water blocking grille 11 extending out of the storage box 8 and the door panel 1 is greater than 1 cm and less than 5 cm.

[0027] In a specific embodiment, both sides of the top end surface of the water blocking grille 11 are fixedly provided with shrinkage limiting blocks 14 at the contact points with the slideway 5 , and the width of the shrinkage limiting blocks 14 exposed from the slideway 5 is greater than the width of the opening of the grille telescopic hole 7 .

[0028] In a specific embodiment, an overflow port is provided at the bottom of the storage box 8, and the overflow port is connected to a sewer pipe.

[0029] In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention is described in detail below through specific usage and working principle.

[0030] In specific use, the anti-overflow structure at the threshold of the bathroom according to the utility model is mainly used in small-sized families where the bathroom does not adopt dry and wet separation. The best effect is to install the anti-overflow structure at the threshold of the bathroom while decorating the bathroom. Of course, it is also possible to open the corresponding slide 5 at the corresponding position and open a grid groove under the threshold after the construction is completed. The core of the anti-overflow structure at the threshold of the bathroom lies in the coordinated arrangement and use of the storage box 8, the scroll 13, the water-blocking grille 11, the grille telescopic hole 7, the left slide 9, and the right slide 10.

[0031] In one specific embodiment, torsion springs can be provided at both ends of the reel 13, and the water-blocking grille 11 can be automatically retracted by the resilience of the torsion springs, but the user needs to apply force to the shrinkage limit block 14 to pull it up; in another specific embodiment, the water-blocking grille 11 is made of tough metal. When the shrinkage limit block 14 is opened and contracted, the water-blocking grille 11 automatically pops out of the storage box 8 by the metal resilience of the water-blocking grille 11. When it retracts after use, the metal curling and retraction into the storage box 8 are achieved under the force applied by the user.

[0032] The anti-overflow structure at the threshold of the bathroom can be pulled up and used at any time during daily washing, which can effectively prevent water from splashing outside the door; in addition, for users who adopt small pets, the anti-overflow structure at the threshold of the bathroom can also temporarily serve as a barrier fence.

[0033] To sum up, with the help of the above-mentioned technical scheme of the utility model, by adding an anti-overflow structure at the threshold of the bathroom, the probability of overflow to the outside when there is a lot of water in the bathroom can be effectively reduced. At the same time, it also avoids the situation where water splashes onto the threshold or even outside the door during daily use, reducing the risk of indoor floors, furniture and other property being soaked in water, thereby achieving the technical effect of increasing the service life of indoor home floors and reducing unnecessary economic losses of owners.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
