Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The utility model discloses a concrete embodiment 1 of laborsaving bottle lid, as shown in fig. 1 to 3, laborsaving bottle lid includes bottle lid body 1, and bottle lid body 1 is including the apron 10 that is located the top and locating the edge that encloses of apron 10 edge 11, and in this embodiment, the shape of the apron 10 of bottle lid body 1 is circular, is equipped with the annular edge that encloses 11 at the circular edge of apron 10, and wherein, the diameter size of apron 10 is 40mm, and the height dimension who encloses along 11 is 20 mm. The inner wall of the surrounding edge 10 of the bottle cap body 1 is provided with internal threads (not shown in the figure), the internal threads of the surrounding edge 10 are matched with the external threads of the bottle mouth, the inner side of the cover plate 10 is provided with a sealing ring edge, the sealing ring edge is matched with the edge of the bottle mouth in a squeezing and sealing mode, and the sealing ring edge is matched with the edge of the bottle mouth in a squeezing and sealing mode by screwing the bottle cap body 1.

The outer wall of enclosing along 10 at bottle lid body 1 is equipped with the increase sand grip of vertical extension, increases the sand grip and is circumference interval arrangement enclosing the outer wall along 10, increases the outer wall surface friction power that the sand grip has increased bottle lid body 1 through the setting, the condition of slippage appears easily when preventing that the bottle lid is twisted to the user hand. A screw base 20 is fixed on the top of the cover plate 10, and a screw arm is radially adjustably mounted on the screw base 20, and has a protruding section protruding beyond the edge of the surrounding edge 11 when the screw arm is adjusted to the unscrewed state. In the present embodiment, the screw base 20 is disposed at a middle position of the cover plate 10, and two screw arms are provided, namely a first screw arm 21 and a second screw arm 22, which are distributed at two side positions of the screw base 20 in a central symmetry manner. The first screw arm 21 and the second screw arm 22 are rotatably assembled at the outer side position of the screw base 20, and the first screw arm 21 and the second screw arm 22 are respectively matched with the screw base 20 in a circumferential stopping manner at the unscrewing position.

The first screwing arm 21 and the second screwing arm 22 have the same structure, taking the first screwing arm 21 as an example, the first screwing arm 21 has a first inner arc portion 210, one side edge of the screwing base 20 is provided with a first outer arc portion 201, and the first inner arc portion 210 of the first screwing arm 21 is in concave-convex fit with the first outer arc portion 201 of the screwing base 20. Correspondingly, the second screwing arm 22 has a second inner arc portion 220, the other side edge of the screwing base 20 is provided with a second outer arc portion 202, the second inner arc portion 220 of the second screwing arm 22 is in concave-convex fit with the second outer arc portion 202 of the screwing base 20, and it is ensured that when the two screwing arms are closed, the first screwing arm 21 and the second screwing arm 22 are respectively tightly attached to the screwing base 20 to form a regular shape.
