The button seat can be pressed to release the spring buckle, and the button seat has a fastening part that can be moved to fasten with the fastening hole of the lower nest. The outer end of the connecting pull rope passes over the fixed pulley and is connected to the lower nest. The inner end of the connecting pull rope extends into the multi-section middle rod and is fixedly engaged with the umbrella head. When the safety automatic opening and closing umbrella is in the fully closed state, each section of the multi-section middle rod is fully closed and the folding umbrella ribs are fully closed. The switch assembly is completely hidden in the umbrella head. The fastening part of the button seat is engaged with the fastening hole of the lower nest. The spring buckle of the middle tube is released from the fastening hole of the outer tube. When the safety-type automatic opening and closing umbrella is in the fully open state, all sections of the multi-section central rod are fully extended and the folding umbrella ribs are fully extended. The button seat of the switch assembly is not obstructed by the umbrella head. The fastening part of the button seat is released from the fastening hole of the lower canopy. The spring buckle of the central tube engages with the fastening hole of the outer tube. When the safety-type automatic opening and closing umbrella is in the ready-to-open state, the outer tube and central tube of the multi-section central rod are relatively extended. The button seat of the switch assembly is not obstructed by the umbrella head. The fastening part of the button seat engages with the fastening hole of the lower canopy. The spring buckle of the central tube engages with the fastening hole of the outer tube.

[0009] The lower nest, corresponding to the spring buckle of the middle tube, is provided with a clearance notch for avoiding the switch assembly. The clearance notch and the fastening hole are located on opposite sides of the lower nest.

[0010] The bottom of the middle tube is fitted with a fixing seat, and the fixing seat, the middle tube and the positioning seat are fixedly connected by fixing nails passing through the elongated hole.

[0011] The lower nest is provided with a gripping part located above the fastening hole; when the safety automatic opening and closing umbrella is in the ready-to-open state, the gripping part is located above the umbrella head.

[0012] The umbrella head is fitted with a connector, which has a rope end hole. The inner end of the pull rope is then inserted into the rope end hole to form a rope end. With the above solution, the working principle of this utility model's safe automatic opening and closing umbrella is as follows:

[0013] When the safety automatic opening and closing umbrella of this utility model is in the fully closed state, each section of the multi-section central rod is fully closed and the folding umbrella ribs are fully closed. The switch assembly is completely hidden in the umbrella head. The button seat's fastening part fastens the lower nest's fastening hole, and the spring buckle of the central tube is released from its fastening hole with the outer tube's fastening hole.

[0014] When the automatic safety umbrella of this invention is to be opened from the fully closed state, firstly, the user lowers the umbrella head, causing the umbrella head to drive the outer tube and middle tube of the multi-section central rod to unfold relative to each other; when the umbrella head moves down to the spring buckle that engages with the buckle hole of the outer tube, the buckle part of the button seat is still engaged with the buckle hole of the lower nest, and the button seat of the switch assembly is not blocked by the umbrella head, so the button seat can be pressed by the user. At this time, the automatic safety umbrella of this invention is in the ready-to-open state; then, the user presses the button seat of the switch assembly (lightly presses the button seat), causing the buckle part of the button seat to disengage from the buckle hole of the lower nest. In this way, under the action of the switch spring, each section of the multi-section central rod is fully unfolded. The full unfolding of each section of the multi-section central rod causes the connecting pull cord to fully unfold the folding umbrella ribs, so that the automatic safety umbrella of this invention is in the fully open state.

[0015] When the automatic safety umbrella of this invention is to be closed from the fully closed state, firstly, the user presses the button seat of the switch assembly (press the button seat firmly), which causes the button seat to exert force on the spring buckle that engages with the central tube, causing the spring buckle to disengage from the buckle hole of the outer tube. At this time, under the action of the closing spring of the folding umbrella ribs, the central tube and the outer tube close relative to each other and the folding umbrella ribs are fully closed. At this time, the automatic safety umbrella of this invention is in the half-closed state. Afterward, the user applies force to fully close each section of the multi-section central rod, so that the buckling part of the button seat engages with the buckling hole of the lower nest and the switch assembly is completely hidden in the umbrella head. At this time, the automatic safety umbrella of this invention is in the fully closed state.

[0016] As can be seen from the above, when the automatic safety umbrella of this utility model is in the fully closed state, the switch component is completely hidden in the umbrella head. This prevents the user from accidentally touching the button of the switch component when the umbrella is fully closed, thus avoiding accidental opening of the automatic safety umbrella without the user's notice. This effectively improves the safety of the automatic safety umbrella of this utility model. In addition, when the automatic safety umbrella of this utility model is in the fully closed state, the folding umbrella ribs can be retracted into the umbrella head, resulting in a small closed size.

[0043] The working principle of this utility model's safe automatic opening and closing umbrella is as follows:

[0044] When the safety automatic opening and closing umbrella of this utility model is in the fully closed state, each section of the tube 101 of the multi-section central rod 1 is fully closed and the folding umbrella rib 5 is fully closed. The switch assembly 7 is completely hidden in the umbrella head 4. The fastening part 721 of the button seat 72 fastens the fastening hole 31 of the lower nest 3. The spring buckle 131 of the central tube 13 is released from the fastening hole 112 of the outer tube 11. Since the switch assembly 7 is completely hidden in the umbrella head 4, the user will not accidentally touch the button seat 72 of the switch assembly 7 when the umbrella is fully closed, thus preventing the safety automatic opening and closing umbrella of this utility model from being accidentally opened without people's attention, thereby improving the safety of use.

[0045] When the safety automatic opening and closing umbrella of this utility model is to be opened from the fully closed state, firstly, the user moves the umbrella head 4 down, causing the umbrella head 4 to drive the outer tube 11 and the middle tube 13 of the multi-segment central rod 1 to open relative to each other; when the umbrella head 4 moves down to the point where the spring buckle 131 of the middle tube 13 engages with the buckle hole 112 of the outer tube 11, the buckling part 721 of the button seat 72 is still engaged with the buckling hole 31 of the lower nest 3, and the button seat 72 of the switch assembly 7 is not blocked by the umbrella head 4, so the button seat 72 can be pressed by the user. At this time, the umbrella head 4 is opened. The utility model's safety automatic opening and closing umbrella is in the ready-to-open state; thereafter, the user presses the button seat 72 of the switch assembly 7, causing the latching part 721 of the button seat 72 to disengage from the latching hole 31 of the lower nest 3. Thus, under the action of the switch spring, each section of the tube 101 of the multi-section central rod 1 is fully opened. The full opening of each section of the tube 101 of the multi-section central rod 1 causes the connecting pull rope 8 to drive the folding umbrella rib 5 to fully open, so that the utility model's safety automatic opening and closing umbrella is in the fully opened state.

[0046] When the automatic safety umbrella of this invention is to be closed from the fully open state, firstly, the user presses the button seat 72 of the switch assembly 7, causing the button seat 72 to apply force to the spring buckle 131 that cooperates with the central tube 13, causing the spring buckle 131 to disengage from the buckle hole 112 of the outer tube 11. At this time, under the action of the closing spring 51 of the folding umbrella rib 5, the central tube 13 and the outer tube 11 close relative to each other and the folding umbrella rib 5 is fully closed. At this time, the automatic safety umbrella of this invention is in the half-closed state. Afterward, the user applies force to fully close each section of the tube 101 of the multi-section central rod 1, causing the buckling part 721 of the button seat 72 to engage with the buckling hole 31 of the lower nest 3 and the switch assembly 7 to be completely hidden in the umbrella head 4. At this time, the automatic safety umbrella of this invention is in the fully closed state.

[0047] As can be seen from the above, when the automatic safety umbrella of this utility model is in the fully closed state, the switch component 7 is completely hidden in the umbrella head 4. This prevents the user from accidentally touching the button seat 72 of the switch component 7 when the umbrella is fully closed, thus avoiding accidental opening of the automatic safety umbrella without the user's notice. This effectively improves the safety of the automatic safety umbrella of this utility model. In addition, when the automatic safety umbrella of this utility model is in the fully closed state, the folding umbrella ribs 5 can be retracted into the umbrella head 4, resulting in a small closed size.

[0048] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0049] Cooperate Figures 1 to 4As shown, in Embodiment 1 of this utility model, the multi-segment central rod 1 is a three-segment central rod, that is, the multi-segment central rod 1 includes an inner tube 12, a middle tube 13 and an outer tube 11 that are sequentially connected from top to bottom; and the folding umbrella rib 5 is a corresponding three-fold umbrella rib.

[0050] In the first embodiment of this utility model, the positioning seat 71 is provided with a movable hole 711 on one side, the button seat 72 is movably accommodated in the positioning seat 71 and the outer tube 11 is sleeved on the button seat 72, the inner wall of the button seat 72 is provided with the fastening part 721, and the button seat 72 is provided with a pressing part 722 that is accommodated in the movable hole 711 on one side. The inner side of the pressing part 722 can movably press the spring buckle 131 that cooperates with the middle tube 13. When the pressing part 722 of the button seat 72 is pressed, the fastening part 721 of the button seat 72 is released from the fastening hole 31 of the lower nest 3. The fastening part 721 may have a fastening inclined surface 7211 that slopes inward from top to bottom, so that when the umbrella is closed, the lower end of the lower nest 3 can pass through the fastening part 721 so that the fastening hole 31 of the lower nest 3 can be fastened with the fastening part 721.

[0051] In the first embodiment of this utility model, a limiting protrusion 712 for inserting the button spring 73 can be formed on the inner side of the positioning seat 71, and a limiting recess 723 for sleeved button spring 73 is formed on the outer side of the button seat 72; this arrangement can effectively prevent the button spring 73 from shifting.

[0052] In the first embodiment of this utility model, the lower nest 3 is provided with a notch 32 for avoiding the switch assembly 7 corresponding to the spring buckle 131 that cooperates with the middle tube 13. The notch 32 and the fastening hole 31 are respectively located on opposite sides of the lower nest 3. When the safety automatic opening and closing umbrella of this utility model is in the ready-to-open state, the notch 32 avoids the switch assembly 7, so that the user can press the button seat 72 and the fastening part 721 of the button seat 72 is released from the fastening hole 31 of the lower nest 3.

[0053] In the first embodiment of this utility model, the side wall of the umbrella head 4 is provided with an operation notch 41. When the automatic safety umbrella of this utility model is in the fully open or ready-to-open state, the button seat 72 is housed in the umbrella head 4 and faces the operation notch 41, so that the button seat 72 is not hidden by the umbrella head 4. This arrangement allows the multi-segment central rod 1 to close as much as possible, thereby helping to reduce the closing length of the multi-segment central rod 1, and thus helping to make the size of this utility model small when fully closed. It should be noted that the side wall of the umbrella head 4 may not have an operation notch 41. In this case, when the automatic safety umbrella of this utility model is in the fully open or ready-to-open state, the switch assembly 7 is above the umbrella head 4, so that the button seat 72 is not hidden by the umbrella head 4.

[0054] In the first embodiment of this utility model, the bottom of the middle tube 13 is fitted with a fixing seat 133, which is lower than the spring buckle 131. The fixing seat 133, the middle tube 13 and the positioning seat 71 are fixedly connected by a fixing nail 9 passing through the elongated hole 111. This connection makes the fixing seat 133, the middle tube 13 and the positioning seat 71 firmly connected and avoids deformation of the middle tube 13.

[0055] In the first embodiment of this utility model, a connector 42 is fitted inside the umbrella head 4. The connector 42 has a rope end receiving hole, and the inner end of the connecting pull rope 8 forms a rope end 81 that is embedded in the rope end receiving hole. This connection allows the inner end of the connecting pull rope 8 to be easily fixed and fitted inside the umbrella head 4. The outer end of the connecting pull rope 8 passes around the fixed pulley 21 and connects to the lower nest 3. It should be noted that the outer end of the connecting pull rope 8 can also pass around the fixed pulley 21 of the upper nest 2 and the movable pulley of the lower nest 3 in sequence before connecting to the upper nest 3.

[0056] Example 2:

[0057] Cooperate Figures 5 to 8 As shown, the difference between Embodiment 2 and Embodiment 1 of this utility model is that: in Embodiment 1, the multi-segment central rod 1 is a three-segment central rod and the folding umbrella rib 5 is a corresponding three-fold umbrella rib; while in Embodiment 2, the multi-segment central rod 1 is a four-segment central rod and the folding umbrella rib 5 is a corresponding four-fold umbrella rib.

[0058] Example 3:

[0059] Cooperate Figures 9 to 12 As shown, the difference between Embodiment 3 and Embodiment 1 of this utility model is that the lower nest 3 of Embodiment 3 is further provided with a gripping part 33 located above the fastening hole 31; when the automatic opening and closing umbrella of this utility model is in the ready-to-open state, the gripping part 33 is above the umbrella head 4. Thus, when the automatic opening and closing umbrella of this utility model is in the fully open state, the user can apply force through the gripping part 33 to drive the lower nest 3 to move downward, so that the inner tube 12 and the middle tube 13 of the multi-segment middle rod 1 are relatively closed, the folding umbrella rib 5 is fully closed, the fastening part 721 of the button seat 72 fastens the fastening hole 31 of the lower nest 3, and the button seat 72 of the switch assembly 7 is not blocked by the umbrella head 4, so that the automatic opening and closing umbrella of this utility model returns to the ready-to-open state, thereby realizing temporary closing of the umbrella. In this way, the user can directly press the button seat 72 to open the umbrella later, which is convenient for the user.

[0060] In the third embodiment of this utility model, a retaining edge 331 is formed on the lower side of the gripping part 33 of the lower nest 3. The retaining edge 331 can facilitate the user to apply force to move the lower nest 3 downward, and at the same time, the retaining edge 331 can also prevent the user's fingers from being pinched by the umbrella head 4.

[0061] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
