Detailed Description

The following detailed description is to be read with reference to the best mode embodiment as shown in the drawings.

As shown in fig. 1, the positioning structure of the umbrella lower nest of the present invention comprises: the umbrella comprises a lower nest 1 which is sleeved on a middle rod of the umbrella in a sliding manner, a button 2 which is arranged on the lower nest 1, an upper lantern ring 3 and a lower lantern ring 5 which are fixedly sleeved on the upper part and the lower part of the middle rod of the umbrella respectively, and an elastic device 6 which is arranged between the lower nest 1 and the button 2 and pushes the button 2 outwards. Wherein,

the upper ring 3 extends downwards to form an upper protruding part 32, the lower ring 5 extends upwards to form a lower protruding part 52, the upper protruding part 32 is provided with an upper concave hole 31, and the lower protruding part 52 is provided with a lower concave hole 51. The upper collar 3 and the lower collar 5 may be secured to the umbrella stick by pins 7.

As shown in fig. 4 or fig. 5, the button 2 includes a pressing portion 22 with a front portion exposed out of the surface of the lower nest 1, and an annular guide portion 23 fixedly disposed behind the pressing portion 22, wherein a protrusion 21 capable of being fastened with the upper concave hole 31 and the lower concave hole 51 is disposed inside the annular guide portion 23, and a vertical convex edge 24 is disposed on each of the left side and the right side.

As shown in fig. 2 and 3, the cavity of the lower nest 1 is provided with a concave 12 capable of accommodating the upward protruding tab 32 and the downward protruding tab 52, the inner wall of the lower nest 1 is annularly provided with a groove 11 capable of accommodating the annular guiding portion 23 and the protruding tab 21 inside the button 2, so that the annular guiding portion 23 can slide in the lower nest 1, and the upper and lower sides of the front opening of the lower nest 1 are respectively provided with small protruding posts 15 with holes, as shown in fig. 1, in this embodiment, the elastic device 6 is a compression spring installed in the holes of the two small protruding posts 15 and abutting against the inner side of the pressing portion 22 of the button 2, thereby generating a continuous external pushing force on the button 2, and meanwhile, in order to prevent the button 2 from being pushed out of the surface of the lower nest 1 excessively, the two sides of the groove 11 of the lower nest 1 are provided with stopping edges 13 for stopping the outward movement of the vertical protruding.

In order to prevent the compression spring from being displaced when being pressed, as shown in fig. 5, a vertical spring positioning groove 25 is formed inside the pressing portion 22 of the button 2 corresponding to the compression spring 6.

In addition, the lower end of the upward tongue 32 and the upper end of the downward tongue 52 are transition slopes or curved surfaces, which facilitate the introduction into the cavity 12 of the lower nest 1.

When the lower nest 1 is pushed to the umbrella closing or opening position, the button 2 is pushed outwards under the action of the elastic device 6, the convex block 21 on the inner side of the annular guide part 23 moves forwards and is just clamped into the lower concave hole 51 or the upper concave hole 31, so that the lower nest 1 is locked; when the pressing part 22 is pressed, the convex block 21 is separated from the lower concave hole 51 or the upper concave hole 31 and is retracted into the groove 11 on the inner wall of the lower nest 1, so that the lower nest 1 is released. After the lower nest positioning structure is adopted, the phenomenon that the strength of the middle rod is damaged due to the fact that the groove hole is formed in the middle rod can be avoided.
