TECHNICAL FIELD
[0001] The utility model relates to a umbrella stand, concretely relates to a lower nest type opening and closing umbrella structure of self-retracting umbrella stand. BACKGROUND
[0002] The existing self-retracting umbrella stand generally comprises a middle rod, an upper nest fixed to the upper end of the middle rod, a lower nest vertically and slidably connected to the middle rod and an umbrella handle installed at the bottom of the middle rod, the upper nest and the lower nest are connected with the self-retracting umbrella stand, and a spring piece is further fixed to the middle rod; when opening the umbrella, the self-retracting umbrella stand is kept in the open state by clamping the lower nest on the spring piece, and when closing the umbrella, the spring piece is controlled to be retracted into the middle rod, at this time, the self-retracting umbrella stand can push the lower nest to move downward along the middle rod to close the umbrella; the existing control of the spring piece retracted into the middle rod generally has two kinds, the first kind: a clamping piece is arranged in the lower nest, the lower nest is clamped between the middle rod and the spring piece through the clamping piece, the spring piece is controlled to be pulled down by pressing the button on the umbrella handle, the clamping piece is pushed out of the middle rod and the spring piece, and the greater the friction between the clamping piece and the middle rod is, the more laborious the spring piece is pulled down; the second kind: the lower nest is clamped above the spring piece, one end of the spring piece is rotatably connected with the middle rod, and the other end is connected with a pull-down rod, the pull-down rod is pulled down by pressing the button on the umbrella handle, and the pull-down rod controls the spring piece to be pulled down, because one end of the spring piece is rotatably connected with the middle rod, and the other end is connected with the pull-down rod, the torque is large when the pull-down rod is pulled down, and it is also more laborious. CONTENT OF THE UTILITY MODEL
[0003] The utility model just in order to solve provides a kind of self-retracting umbrella stand's lower nest type opening and closing umbrella structure technical problem when closing umbrella, it is more relaxed.
[0004] To solve the above technical problem, the technical solution of the lower nest type opening and closing umbrella structure of the self-retracting umbrella stand of the utility model is as follows:
[0005] It comprises a middle rod, an upper nest fixed to the upper end of the middle rod, a lower nest vertically and slidably connected to the middle rod and an umbrella handle installed at the bottom of the middle rod; the upper nest and the lower nest are connected with the self-retracting umbrella stand, and a mounting seat is further connected to the inner upper end of the middle rod; a spring piece is hingedly connected to the lower end of the mounting seat; a clamping convex is connected to the lower end of the spring piece; the outer end of the clamping convex protrudes outward from the middle rod; a guide seat is further vertically and slidably connected to the inner side of the middle rod; the lower end of the spring piece abuts on the guide seat, and a guide surface for guiding the spring piece to be retracted into the middle rod by controlling the guide seat to be moved downward is arranged on the guide seat; a button is slidably connected in the umbrella handle; a control mechanism for controlling the guide seat to be moved downward by pressing the button is connected in the middle rod; a sliding seat is slidably connected in the lower nest; a clamping block corresponding to the clamping convex is connected to the bottom of the sliding seat; the upper surface of the clamping block is a first guide inclined surface, and the lower surface of the clamping block is a clamping surface; a first spring is connected between the clamping block and the lower nest; the clamping block is clamped above the clamping convex through the clamping surface, and the clamping block is slidably arranged in the lower nest through the cooperation of the first guide inclined surface and the clamping convex.
[0006] The control mechanism comprises a lower sliding seat slidingly connected in the middle rod and a control link; the upper end of the control link is fixed on the guide seat, and the lower end of the control link is connected with the lower sliding seat; the lower sliding seat is provided with a second guide inclined surface corresponding to the button, and the button controls the lower sliding seat to move downward through the second guide inclined surface by pressing the button; the lower sliding seat is further provided with a second spring; and the second spring is located between the bottom wall of the middle rod and the lower sliding seat.
[0007] The technical effect achieved by the utility model is that: when the umbrella is opened, the lower nest moves upward along the middle rod, and in the upward moving process, the cooperation of the first guide inclined surface on the clamping block and the clamping convex makes the clamping block slide outward to bypass the clamping convex, at this time, the first spring is compressed, and until the clamping block is bypassed above the clamping convex, at this time, the first spring restores to the original state to push the clamping block back to the original position, the clamping block is clamped above the clamping convex through the clamping surface below the clamping block, and the umbrella keeps the opened state; and in the process of closing the umbrella, only the button needs to be pressed, the button controls the guide seat to move downward through the control mechanism, the guide surface on the guide seat controls the spring sheet to be guided into the middle rod by controlling the downward movement of the guide seat, the lower nest is lowered by the self-closing umbrella frame, the lower nest drives the spring sheet and the clamping convex to be guided into the middle rod through the clamping block, at this time, the lower nest moves downward along the middle rod until the umbrella is closed, therefore, the utility model only needs to control the guide seat to move downward through the control mechanism when the umbrella is closed, that is, there is no large torque and the friction between the existing clamping piece and the middle rod does not need to be solved, so that the umbrella is closed more easily.
