[0005] The lower end of the end plate of the top cover is provided with a gusset plate, and the gusset plate is provided with a locking block;

[0006] The locking block enters the accommodating cavity through the oblique guide groove and is engaged with the locking cavity. The buckle plate is engaged with the accommodating cavity, and the lower end of the buckle plate is opposite to the outer handle recess.

[0007] The improved locking flushing water tank is special in that an inner concave cavity is provided at the lower part of the inner surface of the gusset plate.

[0008] The special feature of the improved locking flushing water tank is that the buckle plate is elastic.

[0009] The improved locking flushing water tank is special in that the locking block is in the shape of a frame with a bottom opening, and the longitudinal frame edges are rounded.

[0010] The utility model provides a flushing water tank with improved locking. Due to the structure, the mold structure of the top cover and the water tank is simple and the manufacturing is convenient. When disassembling, it only needs to push up the buckle plate to achieve disassembly, and little force is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0018] like Figure 1 As shown, an improved locking flushing water tank includes a water tank 1 with an upper opening and a top cover 2 with a lower opening. The upper opening of the water tank is provided with an external interface 11; the top cover 2 is made of plastic material; the external interface 11 is inserted into the top cover 2, and the upper end of the water tank 1 supports the lower end of the top cover 2;

[0019] The external interface 11 is provided with an oblique guide groove 111, and the side wall plate of the water tank 1 adjacent to the oblique guide groove 111 is provided with an upper opening and an end-opening accommodating cavity 12 and an external hand-picking recess 13, and the bottom plate of the accommodating cavity 12 is provided with an end-opening locking cavity 14; the bottom plate of the oblique guide groove 111 forms an acute angle with the horizontal plane in the water tank;

[0020] The lower ends of the two end plates of the top cover 2 are respectively provided with gusset plates 21, and the gusset plates 21 are provided with locking blocks 22;

[0021] The locking block 22 enters the accommodating cavity 12 through the oblique guide groove 111 and engages with the locking cavity 14 . The buckle plate 21 engages with the accommodating cavity 12 , and the lower end of the buckle plate 21 faces the outer handle recess 13 .

[0022] As a further improvement of the present invention, the lower portion of the inner surface of the gusset plate 21 is provided with an inner concave cavity 211. With such a structure, the finger enters the inner concave cavity 211 through the outer hand-gripping recess 13, and it is convenient to push up or pull the gusset plate 21.

[0023] The gusset plate 21 is elastic.

[0024] The locking block 22 is in the shape of a frame with a lower opening, and the longitudinal frame edge 221 has rounded corners 222. In other words, the longitudinal frame edge 221 is in the shape of an arc. In other words, the surface of the locking block 22 facing the end wall of the water tank is in the shape of an arc. With such a structure, the friction between the locking block and the oblique guide groove and the bottom plate of the accommodating cavity is small, and assembly is quick and convenient.

[0025] When removing the top cover 2 of the utility model, the fingers enter the inner cavity 211 through the outer hand-gripping recess 13, and then lift up and push the buckle plate outward to achieve quick removal;

[0026] During assembly, the top cover 2 and the external interface 11 are opposite to each other, and then moved toward the water tank 1, the locking block 22 slides with the oblique guide groove 111 and the bottom plate of the accommodating chamber, the buckle plate 21 and the locking block 22 enter the accommodating chamber, and then continue to move, the locking block enters the locking chamber, and the top of the locking block buckles with the top plate of the locking chamber; since the oblique groove and the accommodating chamber are external, it is convenient to identify.

[0027] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
