Detailed Description

The present invention will be described in more detail with reference to the embodiments shown in the drawings.

As shown in fig. 1 and fig. 2, the push-pull nest structure of the present invention comprises: the umbrella comprises a middle rod 1, an upper nest 2 fixed at the top of the middle rod 1, a movable nest 3 sleeved on the middle rod 1 in a sliding manner, and a buckle device 4 used for locking the movable nest 3 at an umbrella opening position. The middle rod 1 can be a straight rib umbrella middle rod with only one section of pipe fitting, or a folding middle rod formed by sliding sleeving of a plurality of sections of pipe fittings. The movable nest 3 comprises a nest body 31 and a sleeve 32, the sleeve 32 is sleeved outside the lower part of the nest body 31 in a sliding way up and down, the sleeve 32 is pushed upwards to move the umbrella on the movable nest 3, and the sleeve 32 is pulled downwards from the umbrella opening position to trigger the buckling device 4 to release the movable nest 3 to realize umbrella folding.

The lower part of the upper nest 2 is provided with a horizontal slotted hole 21, and the slotted hole 21 can transversely penetrate through the lower part of the lower nest 2 or only penetrate through the front surface of the upper nest 2. In this embodiment, as shown in fig. 1 and fig. 3, the lower part of the upper nest 2 is plugged into the top of the inner cavity of the middle rod 1, and the side wall of the top of the middle rod 1 is provided with a through hole 11 at a position corresponding to the front opening of the slot 21 of the upper nest 2.

The locking device 4 is mounted in the slot 21 and comprises a locking piece 41 and a spring 42 acting forward on the locking piece 41. In this embodiment, the elastic member 42 is a spring, and the spring 42 is pressed between the back of the locking piece 41 and the wall surface of the back of the slot 21, so that the locking piece 41 is pushed forward by the spring 42 and has a tendency to extend out of the slot 21 and the through hole 11 at the top of the middle rod 1.

As shown in fig. 5, the latch 41 is a vertically disposed plate structure, a horizontal step surface 411, a top guiding inclined surface 412 located in front of the horizontal step surface 411, and a vertical step surface 414 located behind the horizontal step surface 411 are disposed on a front top surface of the latch 41, and a bottom guiding inclined surface 413 is disposed on a front bottom surface of the latch 41, so that a front portion of the latch 41 is pointed. The width of the locking piece 41 is slightly smaller than the total width of the slot 21 and the top through hole 11 of the middle rod 1, the height of the locking piece 41 at the horizontal step surface 411 is slightly smaller than the height of the top through hole 11 of the middle rod 1, so that the vertical step surface 414 is locked in the inner cavity of the middle rod 1, the part of the locking piece 41 behind the vertical step surface 414 cannot be separated from the middle rod 1, and the part of the locking piece 41 forward from the vertical step surface 414 can protrude out of the middle rod 1 without being blocked.

As shown in fig. 1, the nest body 31 has a ring nest portion 311 protruding from the middle thereof for connection with umbrella ribs, an upper extension tube 312 at the upper portion thereof, and a lower extension tube 313 at the lower portion thereof. The front side wall of the upper part of the upper extension pipe 312 is provided with a buckle through hole 33 for the buckle sheet 41 to extend out, and the sleeve 32 is sleeved outside the lower extension pipe 313 and slides up and down for a certain distance. The upper part of the nest body 31 is also provided with an unlocking piece 34 connected with the sleeve 32, and the unlocking piece 34 at least vertically corresponds to the top guide inclined plane 412 of the buckling piece 41.

In this embodiment, the unlocking member 34 is a collar that is sleeved on the top of the upper extension tube 312, and the collar 34 is connected to the sleeve 32 through two diametrically opposite left and right vertical connecting rods 35, so that the sleeve 32 and the collar 34 can slide up and down synchronously. Of course, the two links 35 avoid the opening position of the slot 21.

In this embodiment, as shown in fig. 1 and 4, the connecting rod 35 is installed in the inner cavity of the nest body 31, the communicating holes 314 are formed on both the left and right side walls of the down-extending pipe 313, and the bottom of the connecting rod 35 is connected with the inner wall of the sleeve 32 through the communicating holes 314. The outer side wall of the bottom of the connecting rod 35 is provided with a horizontal clamping groove 351 which is formed by two bulges in a clamping way, the inner wall of the sleeve 32 is provided with a convex key 321, the convex key 321 is just embedded into the clamping groove 351 so as to connect the bottom of the connecting rod 35 with the inner wall of the sleeve 32, and the convex key 321 and the clamping groove 351 cannot be separated as long as the middle rod 1 is arranged in the inner cavity of the nest body 31.

As shown in figure 6, when the sleeve 32 is pushed upwards, the nest body 31 will move upwards along the middle rod 1, when the top of the nest body 31 abuts against the bottom guiding inclined plane 413 of the fastening piece 41 protruding out of the middle rod 1, the fastening piece 41 will be pushed to retract towards the inside of the slot 21, and the nest body 31 can move upwards continuously to the umbrella opening position shown in figure 7, at this time, the fastening through hole 33 formed on the front side wall of the upper extension tube 312 is opposite to the opening position of the slot 21, the fastening piece 41 protrudes from the fastening through hole 33, and the top of the fastening through hole 33 is clamped at the horizontal step surface 411 at the top of the fastening piece 41, so as to lock the movable nest 3.

When the sleeve 32 is pulled downwards in the open state, as shown in fig. 8, the unlocking piece 34 moves downwards synchronously to abut against the top guide inclined surface 412 of the locking piece 41 to push the locking piece 41 inwards to the inner side of the unlocking piece 34, and at this time, the horizontal step surface 411 at the top of the locking piece 41 is separated from the top of the locking through hole 33 to release the locking of the movable nest 3. When the sleeve 32 is pulled downwards, the nest body 31 moves downwards, as shown in fig. 9, the top of the snap through hole 33 abuts against the top guide inclined plane 412 of the snap sheet 41 to push the snap sheet 41 inwards continuously, so that the movable nest 3 can move downwards to realize the umbrella folding action.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. 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.
