[0029] like Figures 1 to 5 As shown, a one-handed opening and closing umbrella comprises an umbrella rib assembly 1, a middle rod assembly 2 and a handle 3. The umbrella rib assembly 1 comprises an umbrella rib support group, an upper nest, a lower nest and an umbrella closing spring; the upper nest is fixed to the top of the middle rod assembly 2, and the lower nest is slidably connected to the middle rod assembly 2; one end of the umbrella rib support group is pivotally connected to the upper nest, one end is pivotally connected to the umbrella spring, and the other end is pivotally connected to the lower nest, and the lower nest provides a pulling force for opening and closing the umbrella when sliding up and down along the middle rod assembly 2. A telescopic mechanism 4 is provided in the middle rod assembly 2, and the telescopic mechanism 4 comprises a first end and a second end; the second end is connected to the umbrella rib assembly 1, and the driving force of the telescopic mechanism 4 during extension or contraction is used to drive the lower nest to slide up and down along the middle rod assembly 2, so that the umbrella rib assembly 1 is opened or closed. The handle 3 is provided with a driving mechanism 5, a locking mechanism 6 and an unlocking mechanism 7; the driving mechanism 5 is pressed to drive the telescopic mechanism 4 to extend until the first end is locked in the locking mechanism 6, at which time the rib assembly 1 reaches a fully opened state, and the rib assembly 1 is kept in an open state by the locking mechanism 6. The unlocking mechanism 7 is used to drive the first end to exit the locking mechanism 6 so that the telescopic mechanism 4 can be retracted. The one-handed opening and closing umbrella structure provided in this embodiment is cleverly designed and easy to operate; by providing the telescopic mechanism 4 in the middle rod assembly 2 and the driving mechanism 5, the locking mechanism 6 and the unlocking mechanism 7 in the handle 3, the opening and closing of the umbrella can be realized by one-hand operation, thereby improving the practicality and user experience of the umbrella.

[0030] In the specific implementation of this embodiment, the telescopic mechanism 4 is a cross-link mechanism, which is composed of a plurality of lifting rods 41 that cross each other, and the number of lifting rods 41 is determined according to the length of the middle rod assembly 2; by pressing the driving mechanism 5 to drive the lifting rods 41 to straighten, the cross-link mechanism is extended, and the umbrella rib assembly 1 is driven to open. Conversely, when the cross-link mechanism is retracted in the opposite direction, the umbrella rib assembly 1 is driven to fold. This design not only ensures the stability of the structure, but also makes the extension and retraction of the umbrella smoother.

[0031] In the specific implementation of this embodiment, two mutually intersecting long moment lifting rods 42 are provided at the first end, and the longer moment can provide a longer telescopic distance for the cross-link mechanism to adapt to the length of the middle rod assembly 2 and the opening and closing force of the umbrella rib assembly 1. When in use, the long moment lifting rod 42 is driven to straighten by pressing the driving mechanism 5, thereby driving the cross-link mechanism to extend until the first end is locked in the locking mechanism 6. Two mutually intersecting short moment lifting rods 43 are provided at the second end, and the short moment lifting rods 43 are connected to the umbrella rib assembly 1. During the extension of the cross-link mechanism, the short moment lifting rods 43 drive the umbrella rib assembly 1 to gradually open.

[0032] In the specific implementation of this embodiment, the driving mechanism 5 includes two driving members 51 corresponding to the two mutually crossed long moment lifting rods 42, the driving member 51 is rotatably connected to the handle 3, and the inner side of the driving member 51 is in contact with the long moment lifting rod 42. When the driving member 51 is pressed, the driving member 51 moves toward the center of the handle 3, and the inner side of the driving member 51 pushes the long moment lifting rod 42 to extend the cross-link mechanism.

[0033] In the specific implementation of this embodiment, the end of the long moment lifting rod 42 is provided with a first buckle part 421, and the locking mechanism 6 is provided with a second buckle part 621, and the first buckle part 421 and the second buckle part 621 are detachably clamped and matched. The driving mechanism 5 drives the long moment lifting rod 42 to straighten, thereby driving the cross-link mechanism to extend until the first buckle part 421 of the long moment lifting rod 42 is clamped and fixed with the second buckle part 621, at which time the umbrella rib assembly 1 reaches a fully opened state and remains locked to prevent automatic folding.

[0034] During the specific implementation of this embodiment, the locking mechanism 6 includes an elastic member 61 and a block 62 provided with a second snap portion 621. One end of the elastic member 61 is connected to the handle 3, and the other end is connected to the block 62. The pre-tightening force of the elastic member 61 drives the block 62 to move toward the long-torque lifting rod 42 to achieve a clamping fit between the second snap portion 621 and the first snap portion 421, so that the umbrella remains in an open state.

[0035] During the specific implementation of this embodiment, the unlocking mechanism 7 is slidably connected to the handle 3. Through a simple pushing action, the unlocking mechanism 7 can slide, thereby driving the blocking block 62 to move in a direction away from the long-torque lifting rod 42, so as to separate the second locking portion 621 from the first locking portion 421, so that the first end of the telescopic mechanism 4 exits the locking mechanism 6, and the telescopic mechanism 4 contracts while driving the umbrella rib assembly 1 to fold, thereby conveniently realizing the one-handed umbrella folding operation.

[0036] In the specific implementation of this embodiment, the long moment lifting rod 42 is provided with a stopper 422. When the rib assembly 1 is folded, the stopper 422 contacts the handle 3 to limit the free extension of the cross-link mechanism; when the umbrella is inverted, there is no danger of sudden opening. In the process of opening the umbrella, by pressing the driving mechanism 5 to move the two long moment lifting rods 42 toward the center of the handle 3, the stopper 422 is out of contact with the handle 3, and the cross-link mechanism is extended to drive the rib assembly 1 to open.

[0037] During the specific implementation of this embodiment, a traction mechanism 8 is further provided in the middle rod assembly 2, and the second end is connected to the rib assembly 1 through the traction mechanism 8 to drive the rib assembly 1 to open or fold: when the cross-link mechanism is extended, the rib assembly 1 is driven to open through the traction mechanism 8; when the cross-link mechanism is contracted, the rib assembly 1 is driven to fold through the traction mechanism 8; the torque is changed by the traction mechanism 8 to reduce the pressure on the driving mechanism 5 when opening the umbrella.

[0038] In the specific implementation of this embodiment, the middle rod assembly 2 includes an outer tube 21, an inner tube 22 and a lifting assembly 23; the inner tube 22 is slidably connected to the outer tube 21 to achieve a folding effect; one end of the lifting assembly 23 is fixedly connected to the telescopic mechanism 4, and the other end is connected to the inner tube 22 to drive the inner tube 22 to rise and fall. Specifically, when the telescopic mechanism 4 is extended, the lifting assembly 23 is driven to rise, and then the inner tube 22 is driven to extend outward from the outer tube 21, so that the middle rod assembly 2 is unfolded.

[0039] Regarding the embodiments of the present utility model, it should also be noted that, in the absence of conflict, the embodiments of the present utility model and the features therein can be combined with each other to obtain new embodiments.

[0040] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. The protection scope of the utility model shall be based on the protection scope of the claims. Although the utility model has been disclosed as a preferred embodiment, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modify the technical content disclosed above to an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
