CN202954421U - Toilet flushing water tank - Google Patents

Abstract

The utility model discloses a toilet flushing water tank which comprises a tank body and a tank cover, wherein a water intake hole and a water discharge hole are formed in the bottom of the tank body; the tank cover and the tank body are detachably connected; notches are formed in the upper part of two side plates of the tank body; an elastic plate is arranged inside each notch; a clamping groove is formed in the upper part of each elastic plate; two angular limiting plates are arranged on two sides of a joint of the tank cover; clamping tongues are arranged on inner walls of the joints at the upper parts of the angular limiting plates; one of the angular limiting plates is embedded into a gap between the end surface of each elastic plate and the corresponding notch; the other limiting plate is adhered to the outer surface of the elastic plate; and the clamping tongues are fitted with the clamping grooves. When the elastic plates on the notches on the two sides of the tank body are dragged, the elastic plates move inwards to the tank body, thereby separating the clamping tongues from the clamping grooves. A limiting buckle at the front part of the tank cover is matched with a limiting groove in the top part of the a front wall plate of the tank body, and upper limiting columns on the side walls of inner recesses on two sides of a rear wall plate of the tank body are matched with rear recess at the rear part of the joint of the tank cover, and therefore, by adopting the structure, the tank body is prevented from deformation after being filled with water, and the service life is prolonged.

Description

A kind of toilet cistern

Technical field

The utility model relates to a kind of toilet cistern.

Background technology

Currently available technology, a kind of toilet cistern, comprise casing and case lid, and described bottom half has inlet opening and drain hole, and case lid and casing removably connect.Existing problems are: in use, case lid is difficult to separate with casing, must apply very large external force and make just can open case lid after box deformation, causes maintenance, clean very inconvenient, has shortened the application life of casing simultaneously.In addition, because casing and case lid lack fastening devices effectively, can not effectively suppress the trend that casing expands outwardly after water filling, thereby make box deformation, cause the case lid Automatic-falling, shorten the application life of water tank.

Summary of the invention

The purpose of this utility model is: a kind of toilet cistern is provided, and it can effectively easily be opened case lid and prevent the distortion of water storage rear box from casing, increases the service life.

The utility model is achieved in that a kind of toilet cistern, comprise casing and case lid, described bottom half has inlet opening and drain hole, case lid and casing removably connect, its special character is: the biside plate top of described casing is jagged, one elastic plate is arranged in breach, and draw-in groove is arranged at the top of elastic plate;

On the soffit of described case lid, interface is arranged, the both sides of described interface are provided with two dihedral limiting plates, on the interface inwall on dihedral limiting plate top, block tongue are arranged;

Described dihedral limiting plate one limiting plate embeds the end face of elastic plate and the gap between breach, the external surface laminating of another limiting plate and elastic plate, and block tongue and draw-in groove are chimeric.

Described a kind of toilet cistern, its special character is: on described draw-in groove place elastic plate, the level of falling is arranged, the lower surface of the interface between described two dihedral limiting plates with fall level and coordinate stop bit.

Described a kind of toilet cistern, its special character is: the spacing button of the front portion of described case lid, the rear portion of the interface of described case lid rear protruding position arranged;

The top limited location groove of the front panel of described casing, upper breach is arranged at squab panel top, and there is interior recess the both sides of the squab panel of upper indentation, there, limited location post on the sidewall of interior recess;

Spacing button and stopper slot are chimeric, the inner surface of rear protruding position and limited post laminating.

A kind of toilet cistern of the utility model, owing to adopting such structure, scratch the elastic plate on moving casing two side breach, and elastic plate moves in casing, thereby easily realizes block tongue and exact separation, reaches the purpose that case lid is separated with casing.The stopper slot at the top of the spacing button of case lid front portion and the front panel of casing coordinates, protruding position cooperation behind the rear portion of the sidewall upper limit post of recess and case lid interface in casing squab panel both sides, owing to adopting such structure, after preventing water filling, box deformation, extended application life.

The specific embodiment

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

As shown in Figure 1, a kind of toilet cistern, comprise casing 1 and case lid 2, inlet opening and drain hole are arranged at described casing 1 bottom, and case lid 2 and casing 1 removably connect, the biside plate top jagged 11 of described casing 1, one elastic plate 12 is arranged in breach 11, and draw-in groove 13 is arranged at the top of elastic plate 12;

Interface 3 is arranged on the soffit of described case lid 2, and the both sides of described interface 3 are provided with two dihedral limiting plates 4, on interface 3 inwalls on dihedral limiting plate 4 tops, block tongue 31 are arranged;

Described dihedral limiting plate 4 one limiting plates embed the end face of elastic plate 12 and the gap between breach 11, the external surface laminating of another limiting plate and elastic plate 12, and block tongue 31 is chimeric with draw-in groove 13.

Have on described draw-in groove 13 place's elastic plates and fall level 14, the lower surface of the interface 3 between described two dihedral limiting plates 4 with fall grades 14 and coordinate stop bit.

The spacing button 21 of the front portion of described case lid 2, the rear portion of the interface 3 of described case lid 2 rear protruding position 22 arranged;

The top limited location groove 15 of the front panel of described casing 1, upper breach 5 is arranged at squab panel top, and there is interior recess 16 both sides of the squab panel at upper breach 5 places, limited location post 6 on the sidewall of interior recess 16;

Spacing button 21 is chimeric with stopper slot 15, and spacing button 21 and stopper slot 15 are respectively swallow-tail form, inner surface limited post 6 laminatings of rear protruding position 22.Adopt such scheme, after can preventing casing 1 water filling, the Directional Extension of wallboard forwards, backwards of casing 1.

Interface 3 inserts in casing 1, and in 22 embeddings place of rear protruding position, in breach 5, the top surface of the lower surface of rear protruding position 22 and the squab panel at upper breach 5 places is fitted.

Above-described is only preferential embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, in the situation that do not break away from the utility model principle, can also make some improvement and modification, this also is considered as protection domain of the present utility model.
