Detailed Description

Embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.

Example (b):

referring to fig. 1 to 8, a non-falling-plate same-floor drainage system and a bathroom are provided, and the embodiment is applied to drainage of a building without falling plates in the same floor.

A non-descending plate same-layer drainage system is disclosed, and is shown in a figure 1, and comprises a bathroom chassis 1 and a plurality of height adjusting and supporting assemblies 2 arranged at the bottom of the bathroom chassis 1, wherein a water outlet at the bottom of the bathroom chassis 1 is connected with a drainage pipe 3 at the same layer, the height of the bathroom chassis 1 is raised through the height adjusting and supporting assemblies 2, a space is provided for realizing drainage at the same layer at the bottom of the bathroom chassis 1, a floor slab does not need to be grooved and holed or subjected to plate descending treatment, the workload is small during installation, and the installation is convenient; bathroom chassis 1's circumference is equipped with waterproof enclosure 4, prevents that water from overflowing around bathroom chassis 1, be equipped with entrance door 4.1 on the waterproof enclosure 4, entrance door 4.1 department still is equipped with the step 5 that is used for stepping on bathroom chassis 1, and the personnel of being convenient for get into the bathroom chassis 1 of height by the lifting from waterproof enclosure 4 outside through step 5.

Referring to fig. 1 to 3, an anti-slip pad 6 is detachably disposed on one side of the bathroom chassis 1 close to the entrance door 4.1 to prevent a person from slipping down when stepping on the bathroom chassis 1, and anti-slip patterns 6.3 are disposed on an upper surface of the anti-slip pad 6 to increase friction. In order to prevent people from stepping on the bathroom base plate 1 and slipping down, anti-slip measures such as anti-slip lines and the like can be arranged on the upper surface of the bathroom base plate 1.

The bathroom chassis 1 is of a concave structure with a low center and a high edge, so that accumulated water can conveniently flow into a water outlet in the middle; the edge of the bathroom base plate 1 is provided with a slide rail 1.1, and the length direction of the slide rail 1.1 points to the outer side of the edge of the bathroom base plate 1 from the inner side of the edge of the bathroom base plate 1; the antiskid pad 6 is provided with a sliding groove 6.1 matched with the sliding rail 1.1;

the bottom of the anti-skid pad 6 is provided with a plurality of rows of anti-skid teeth 6.2 along the length direction of the slide rail 1.1; the top of the bathroom chassis 1 is provided with a plurality of rows of raised lines 1.2 along the length direction of the slide rails 1.1, and the raised lines are used for limiting the anti-slip teeth 6.2.

In this embodiment, two sliding rails 1.1 are disposed on the edge of the bathroom chassis 1 near the entrance door 4.1, and two sliding grooves 6.1 are correspondingly disposed on the anti-slip mat 6, during assembly, the anti-slip mat 6 is disposed on the inner side of the edge of the bathroom chassis 1, so that one end of each sliding groove 6.1 is matched with one end of the corresponding sliding rail 1.1, and the anti-slip mat 6 is pushed to the outer side from the inner side of the edge of the bathroom chassis 1 by force until the outer edge of the anti-slip mat 6 is flush with the outer side of the edge of the bathroom chassis 1. In the pushing process, as the non-slip mat 6 is made of elastic materials, the non-slip teeth 6.2 can cross the raised lines 1.2 through deformation, and the non-slip mat 6 is installed; after the installation is accomplished, the sand grip 1.2 realizes spacing the antiskid of slipmat 6 with the cooperation of antiskid tooth 6.2.

In this embodiment, the sliding groove 6.1 is in a state where one end is communicated with the outer side surface of the non-slip mat 6 and the other end is closed, as shown in fig. 6, the non-slip mat 6 can be limited in the length direction of the sliding rail 1.1 in the installation process, and when the end surface of the sliding groove 6.1 close to the inner side is in contact with the end surface of the sliding rail 1.1 close to the inner side, it indicates that the non-slip mat 6 is installed in place, and the non-slip mat 6 is prevented from further sliding forward. The cross section of the sliding rail 1.1 along the length direction is a T-shaped cross section, the sliding groove 6.1 is a T-shaped sliding groove matched with the sliding rail, and the anti-slip mat 6 can be prevented from being easily separated from the top of the bathroom chassis 1 while the installation and the guiding of the anti-slip mat 6 are realized.

The anti-skid teeth 6.2 are provided with first partition notches along the width direction of the sliding rail 1.1, as shown in fig. 6, in the embodiment, four rows of anti-skid teeth 6.2 are arranged at the bottom of the anti-skid pad 6, and each row of anti-skid teeth 6.2 is divided into three sections through one partition notch; the raised lines 1.2 are provided with two partition gaps second along the width direction of the slide rail 1.1, as shown in fig. 7, in the embodiment, two rows of raised lines 1.2 are provided at the top edge of the sanitary ware chassis 1, and each row of raised lines 1.2 is divided into three sections by two partition gaps; the first partition notch and the second partition notch are oppositely arranged, as shown in fig. 5, liquid is conveniently discharged, and accumulated water is prevented from accumulating between the anti-skidding teeth 6.2 and the convex strips 1.2, so that the bottom of the anti-skidding mat 6 becomes dirty.

In the use, the people steps on slipmat 6, and what apply is the power of vertical direction, guarantees to have great contact force between non-slip tooth 6.2 and the sand grip 1.2, and in addition the frictional force between slipmat 6 and the bathroom chassis 1 makes slipmat 6 can't overcome the resistance of horizontal direction and realizes the horizontal migration, and slipmat 6 is deviate from bathroom chassis 1 edge when can avoiding the people to step on slipmat 6, leads to personnel to be injured.

When needing to wash slipmat 6, pull slipmat 6 from the outside at bathroom chassis 1 edge to the inboard, because vertical direction is not pressed between anti-skidding tooth 6.2 and the sand grip 1.2 so the contact friction is less, and the resistance of pulling slipmat 6 is also little, when pulling slipmat 6, can upwards lift slipmat 6 edge slightly, reduces the area of contact between anti-skidding tooth 6.2 and the sand grip 1.2, makes the dismantlement process more laborsaving.
