Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent closestool cover plate assembly, in particular to the intelligent closestool cover plate assembly with opening limiting function. BACKGROUND

[0002] After the user opens the intelligent closestool cover plate, due to insufficient opening angle, too fast opening speed, too large force and other factors, the cover plate cannot be effectively self-standing, therefore, after opening the closestool cover plate, the closestool cover plate needs to be temporarily held to ensure that the closestool cover plate is self-standing stably and avoid falling down against the operator's will. In order to overcome the problem that the cover plate is not self-standing stably and easily falls down accidentally, the current main used way is to additionally apply elastic torsion in the opening direction to the cover plate by using a torsion spring structure, but this increases the assembly difficulty of the cover plate and the cost increases greatly due to the large structure improvement range.

[0020] Please refer to Figures 1 to 5The toilet cover assembly with opening limiting function comprises a back cover 10, a cover plate 20 and a damper 30 for realizing slow falling of the cover plate. The cover plate 20 is rotatably connected to the back cover 10, and the damper 30 is arranged inside the back cover 10. The damper 30 comprises a housing and a central shaft. The central shaft of the damper 30 extends from one side of the back cover 10 and is inserted into the cover plate 20. The other side of the back cover 10 is drivingly connected to the cover plate 20 through a rotating shaft (not shown in the figure). The central shaft of the damper and the rotating shaft jointly serve as the support structure for the rotation of the cover plate 20, that is, the cover plate rotates around the central shaft and the rotating shaft. The structure of the back cover 10, the cover plate 20 and the damper 30 is known to those skilled in the art. The central shaft of the damper 30 is non-circular in cross-section, so that it rotates together with the cover plate 20. In addition, the cover plate 20 in the figure comprises an upper cover 22 and a seat ring 24. However, the cover plate 20 can refer to the upper cover 22 or the seat ring 24. Hereinafter, the cover plate 20 refers to one component of the upper cover or the seat ring. The toilet cover assembly further comprises a limiting sleeve 40 and a limiting block 50. The limiting sleeve 40 and the limiting block 50 are provided with a clamping structure. The limiting sleeve 40 is inserted into the housing of the damper 30 and located inside the back cover 10. The limiting block 50 is connected to the central shaft and rotates synchronously with the central shaft. The housing of the damper 30 is fixedly connected to the limiting sleeve 40. The cover plate 20 drives the central shaft and the limiting block 50 to rotate during the opening process. The clamping structure is clamped when the cover plate 20 is opened to a certain angle, so that the cover plate 20 cannot freely fall back in the opposite direction. When the cover plate 20 needs to be closed, the cover plate 20 is manually closed. Under the action of external force, the clamping structure is forcibly separated when the cover plate 20 is manually closed.

[0021] It can be understood that, in the present embodiment, the cover plate 20 comprises an upper cover 22 and a seat ring 24. Therefore, it naturally has two dampers for realizing slow falling of the upper cover and the seat ring respectively, two limiting sleeves inserted into the housings of the two dampers respectively, two limiting blocks connected to the central shafts of the two dampers respectively, and two rotating shafts drivingly connected between the other side of the back cover and the upper cover and between the other side of the back cover and the seat ring respectively. This can be clearly understood by those skilled in the art.

[0022] Preferably, the limiting block 50 is sleeved on the central shaft. Since the central shaft is non-circular in cross-section, the limiting block can rotate synchronously when it is sleeved on the central shaft. The installation structure is very simple.

[0023] Preferably, the clamping structure comprises an active protrusion 52 arranged on the limiting block 50 and a passive protrusion 42 arranged on the limiting sleeve 40. The active protrusion 52 is clamped after passing through the passive protrusion 42.Figure 5 It can be understood that the buckle structure can also be the cooperation of a convex point and a positioning hole, or the cooperation of a friction surface, or the cooperation of an elastic buckle, etc.

[0024] Preferably, the buckle structure further comprises a clearance slot 44 arranged on the limiting sleeve 40, and the active convex block 52 enters the clearance slot 44 when buckled.

[0025] Preferably, the active convex block 52 and the passive convex block 44 are both provided with a guide inclined angle, which is beneficial to buckling and releasing and inevitable to jamming.

[0026] Preferably, the limiting sleeve 40 is locked inside the rear cover 10, and of course, the rear cover can also be provided with a positioning slot for mounting the limiting sleeve.

[0027] Preferably, in the embodiment, when the cover plate comprises an upper cover and a seat ring, the two limiting sleeves 40 respectively inserted with the two damper housings are integrally formed plastic parts.

[0028] The above is only the preferred embodiment of the utility model, and therefore cannot limit the range of the utility model implementation, that is, equivalent changes and modifications made according to the scope and content of the utility model patent should still be within the scope covered by the utility model.
