the button is characterized in that a positioning convex point is arranged on the inner side wall of the rear part of the button, a positioning hole for the insertion of the positioning convex point is formed in the side wall of the rear part of the middle rod, and the positioning convex point and the positioning hole are vertically corresponding in position.

Optionally, the elastic return member is a compression spring.

Furthermore, a small convex column is fixedly arranged on the outer side wall of the rear part of the button, and the front part of the compression spring is sleeved on the small convex column, and the rear part of the compression spring is propped against the inner wall of the movable nest.

The button is in a totally or semi-enclosed roughly annular structure.

Furthermore, the outer walls of the two sides of the button are convexly provided with limit blocks, the inner walls of the two sides of the movable nest are provided with inwards concave limit grooves, and the limit blocks are positioned in the limit grooves and can slide back and forth along the limit grooves.

Further, a lower portion of the movable nest protrudes outward with respect to a middle portion thereof to form a boss portion where the button is installed.

The front end face of the positioning salient point is a smooth cambered surface.

Compared with the prior art, the utility model discloses an umbrella nest locking structure only needs to be equipped with the location bump on button rear portion inner wall simply, and corresponds position department and set up the function that the locating hole can realize locking activity nest on well stick, and the structure is very simple and practical, need not to set up catapult piece or other parts in well stick moreover, assembles convenient and fast more, more saves the manual work.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, and the specific embodiments described herein are only used for explaining the present invention and are not used for limiting the present invention.

As shown in fig. 1 and 4, the umbrella nest locking structure of the present invention comprises: the middle rod 1, a movable nest 2 which is sleeved on the middle rod 1 in a sliding way, a button 3 which is arranged on the movable nest 2, and an elastic reset piece 4 which acts on the button 3. As shown in fig. 2, a window 21 is opened on a side wall of the movable nest 2, the button 3 is installed in the inner cavity of the movable nest 2 from the window 21, a pressing surface 34 for being pressed by a finger of a person is arranged on one side of the button 3, and the pressing surface 34 is exposed out of the outer surface of the movable nest 2 from the window 21.

For convenience of description, herein are defined: the button 3 has a front portion on one side of the pressing surface 34 and a rear portion on the opposite side, and the directions of the front and rear portions of the remaining components are the same as those of the button 3.

As shown in fig. 2, 3 and 5, the button 3 is a totally or semi-enclosed annular structure and movably sleeved outside the middle rod 1, the front portion of the button is provided with the pressing surface 34, the inner side wall of the rear portion of the button 3 is fixedly provided with a positioning convex point 31, the outer side wall of the rear portion of the button 3 is fixedly provided with a small convex column 32, and the outer walls of two sides of the button 3 are convexly provided with limit blocks 33.

In this embodiment, the elastic restoring member 4 is a compression spring, the front portion of the compression spring 4 is sleeved on the small convex pillar 32, and the rear portion of the compression spring 4 is pressed against the inner wall of the rear portion of the movable nest 2, so that the compression spring 4 pushes the button 3 forward to keep the button 3 moving forward. The small convex column 32 makes the compression spring more reliably installed at the back of the button 3 and not easy to fall off.

As shown in fig. 2, the inner walls of the two sides of the movable nest 2 are provided with concave limiting grooves 22, and the limiting blocks 33 are installed in the limiting grooves 22 and can slide back and forth along the limiting grooves 22, so that the button 3 can slide back and forth for a certain distance relative to the movable nest 2.

As shown in fig. 3 or 4, a positioning hole 11 for inserting the positioning convex point 31 is formed on a rear side wall of a proper position of the middle rod 1, and the positions of the positioning convex point 31 and the positioning hole 11 vertically correspond to each other. As shown in FIG. 3, when the movable nest 2 slides along the middle rod 1 to the position where the positioning convex points 31 and the positioning holes 11 horizontally correspond, the compression spring 4 pushes the button 3 forwards to move outwards, the positioning convex points 31 at the back of the button 3 are inserted into the positioning holes 11 on the side wall of the middle rod 1, and the movable nest 2 can be locked at the position. When the movable nest 2 is to be released, as shown in fig. 4, the button 3 is simply pressed backwards, the positioning salient point 31 on the button 3 is moved backwards out of the positioning hole 11 of the middle rod 1, and at this time, the movable nest 2 can be released and can slide upwards or downwards along the middle rod 1. Therefore, the movable nest 2 can be locked at the position of the positioning hole only by arranging the positioning hole at the position, where the movable nest 2 needs to be locked, on the side wall of the middle rod 1.

In order to insert the positioning hole 11 on the side wall of the central rod 1 more smoothly, the front end surface of the positioning salient point 31 is provided with a smooth cambered surface.

In addition, as shown in fig. 1, the movable nest 2 is provided with a ring nest portion 24 connected with umbrella ribs on the top, a neck portion 25 with a smaller diameter on the middle, and a boss portion 23 formed by protruding the lower portion of the movable nest 2 relative to the neck portion 25, which makes the operation easier when the movable nest 2 is pulled down by hand. The button 3 is mounted right at the large boss portion 23, which provides a sufficient space for the button 3 to move, and facilitates the formation of the above-mentioned structure with a small middle portion and a large lower portion.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art can make various modifications and variations. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
