TECHNICAL FIELD
[0001] The utility model relates to a umbrella stand, concretely relates to a spring piece type umbrella closing and opening 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 slidingly 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 the middle rod is further fixed with a spring piece; when opening the umbrella, the self-retracting umbrella stand is kept in the open state by clamping the spring piece 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: the lower nest is provided with a clamping piece, 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 rotationally 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, the button controls the pull-down rod to pull down the spring piece, one end of the spring piece is rotationally connected with the middle rod, and the other end is connected with the pull-down rod, so the moment of force is large when pulling down, and it is also more laborious. CONTENT OF THE UTILITY MODEL
[0003] The utility model is just to solve the technical problem of providing a spring piece type umbrella closing and opening structure of self-retracting umbrella stand which is more relaxed when closing the umbrella.
[0004] To solve the above technical problem, the technical solution of the spring piece type umbrella closing and opening structure of self-retracting umbrella stand of the utility model is:
[0005] The umbrella includes a central rod, an upper canopy fixed to the upper end of the central rod, a lower canopy vertically slidably connected to the central rod, and a handle installed at the bottom of the central rod; a self-folding umbrella frame connects the upper and lower canopies; a mounting base is also connected inside the upper end of the central rod; an upper sliding seat is vertically slidably connected below the mounting base; a first spring connects the upper sliding seat and the mounting base; a spring plate is hinged to the lower end of the upper sliding seat; a locking protrusion is connected to the lower end of the spring plate; a vertical groove corresponding to the locking protrusion is formed on the central rod; the locking protrusion passes through the vertical groove and protrudes outward; a vertical groove is also formed on the inner side of the central rod. A guide seat is slidably connected; the lower end of the spring abuts against the guide seat, and the guide seat is provided with a guide surface that guides the spring to retract into the central rod by controlling its downward movement; a button is slidably connected inside the umbrella handle; a control mechanism is connected inside the central rod that controls the guide seat to move downward by pressing the button; a locking block corresponding to the locking protrusion is connected inside the lower nest; the upper surface of the locking block is a first guide slope, and the lower surface of the locking block is a locking surface; the locking block locks onto the upper part of the locking protrusion through the locking surface, and the locking block pushes the locking protrusion into the central rod through the first guide slope.
[0006] The control mechanism includes a sliding lower seat and a control link slidably connected within the central rod; the upper end of the control link is fixed to the guide seat, and the lower end of the control link is connected to the sliding lower seat; the sliding lower seat has a second guide slope corresponding to the button, and by pressing the button, the button controls the sliding lower seat to move downward through the second guide slope; a second spring is also installed below the sliding lower seat; the second spring is located between the bottom wall of the central rod and the sliding lower seat.
[0007] The technical effect achieved by this utility model is as follows: When the umbrella is opened, the lower nest moves upward along the central rod. During this upward movement, the lower nest pushes the upper slide and the spring piece upward through the first guide slope on the locking block (at this time, the first spring is compressed), and the locking protrusion on the spring piece retracts into the central rod along the guide surface on the guide seat during the upward movement. When the locking block of the lower nest is above the locking protrusion, the first spring returns to its original state, pushing the upper slide block downward until the locking protrusion on the spring piece passes through the vertical slide groove and protrudes outward. The locking block of the lower nest is then locked onto the locking protrusion, and the umbrella remains open. During the closing process... During the process, simply press the button. The button controls the guide seat to move downwards via the control mechanism. The guide seat has a guide surface that guides the spring piece to retract into the central rod by controlling its downward movement. The self-closing umbrella frame pushes the lower nest downwards. The lower nest pushes the spring piece and the locking protrusion into the central rod via the locking block. At this time, the lower nest moves downwards along the central rod until the umbrella is closed. Therefore, when closing the umbrella, this utility model only needs to control the guide seat to move downwards via the control mechanism. That is, there is no large torque and there is no need to solve the friction between the existing locking parts and the central rod, so closing the umbrella is relatively easy.
