[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] like Figures 2 to 8 As shown, a retractable umbrella head structure 1 includes an umbrella head outer sleeve 10 installed outside the bottom of the middle rod 2, and an insertion rod 103 is vertically upwardly provided at the bottom of the umbrella head outer sleeve 10. The insertion rod 103 is slidably sleeved in the bottom of the middle rod 2 and can be extended or retracted into the bottom of the middle rod 2. The top opening of the umbrella head outer sleeve 10 extends inward to provide an elastic first retaining edge 101, and an elastic first supporting rib 102 is protruded from the inner wall of the umbrella head outer sleeve 10 below the first retaining edge 101, and a first gap is provided between the first supporting rib 102 and the first retaining edge 101; an umbrella head inner sleeve 11 is slidably sleeved up and down in the umbrella head outer sleeve 10, and an elastic first clamping rib 113 is protruded outward at the bottom of the umbrella head inner sleeve 11, and the first retaining edge 101 is used to limit The first clamping rib 113 moves upward to prevent the inner sleeve 11 of the umbrella head from separating from the outer sleeve 10 of the umbrella head. When the outer sleeve 10 of the umbrella head is pulled downward by an external force, the first clamping rib 113 can move upward relatively and be clamped into the first gap, so that the inner sleeve 11 of the umbrella head extends out of the outer sleeve 10 of the umbrella head. Alternatively, when the outer sleeve 10 of the umbrella head is pushed upward by an external force, the first clamping rib 113 can move downward relatively and slide out of the first gap, so that the inner sleeve 11 of the umbrella head is retracted into the outer sleeve 10 of the umbrella head. Specifically, the inner sleeve 11 of the umbrella head and the outer sleeve 10 of the umbrella head are the same length. Specifically, when the outer sleeve 10 of the umbrella head is pushed upward by an external force, the insertion rod 103 is retracted into the bottom of the middle rod 2. When the outer sleeve 10 of the umbrella head is pulled downward by an external force, the insertion rod 103 is extended out of the bottom of the middle rod 2.

[0029] The present invention can increase or decrease the length of the umbrella head according to the user's wishes to adapt to different usage scenarios. For example, when in use, the outer sleeve 10 of the umbrella head is pulled downward for easy gripping. When it needs to be placed in a bag, the outer sleeve 10 of the umbrella head is pushed upward for easy placement, which is more convenient.

[0030] Furthermore, there are multiple umbrella head inner sleeves 11, and the multiple umbrella head inner sleeves 11 are slidably connected in sequence from the inside to the outside. The top opening of the umbrella head inner sleeve 11 extends inward and is provided with an elastic second retaining edge 114. Except for the innermost umbrella head inner sleeve 11, the inner walls below the second retaining edge 114 of the other umbrella head inner sleeves 11 are all protruding with elastic second supporting ribs 116. There is a second gap between the second supporting ribs 116 and the second retaining edge 114. The first clamping rib 113 of the inner layer of the umbrella head inner sleeve 11 can also slide upward or downward out of the second gap of the outer layer of the umbrella head inner sleeve 11 under the action of external force to extend or retract the outer layer of the umbrella head inner sleeve 11, and the outermost umbrella head inner sleeve 11 slides up and down and is connected in the umbrella head outer sleeve 10.

[0031] Preferably, there are two inner sleeves 11 of the umbrella head, which are divided into a first inner sleeve 111 and a second inner sleeve 112 of the umbrella head. The second inner sleeve 112 is slidably sleeved in the first inner sleeve 111 up and down, and the first inner sleeve 111 is slidably sleeved in the outer sleeve 10 of the umbrella head up and down. The top opening of the first inner sleeve 111 is provided with an elastic second retaining edge 114 extending inward. An elastic second supporting rib 116 is convexly provided on the inner wall of the first inner sleeve 111 below the second retaining edge 114. A second gap is provided between the second supporting rib 116 and the second retaining edge 114. The second retaining edge 114 is used to limit the upward movement of the first clamping rib 113 of the second inner sleeve 112 to prevent the second inner sleeve 112 from separating from the first inner sleeve 111 when an external force is applied. When the outer sleeve 10 of the umbrella head is pulled downward, the first clamping rib 113 of the second inner sleeve 112 of the umbrella head moves upward relatively and is clamped into the second interval, so that the second inner sleeve 112 of the umbrella head extends out of the first inner sleeve 111, or, when the outer sleeve 10 of the umbrella head is pushed upward by an external force, the first clamping rib 113 of the second inner sleeve 112 moves downward relatively and slides out of the second interval, so that the second inner sleeve 112 is retracted into the first inner sleeve 111; specifically, the second inner sleeve 112 of the umbrella head is the same length as the first inner sleeve 111, and the second inner sleeve 112 can increase the length of the umbrella head structure 1 of the utility model when extended, and can adapt to the grip of people with larger palms, but the length of the umbrella head structure 1 after contraction does not increase, that is, the length of the outer sleeve 10 of the umbrella head.

[0032] Further, the middle rod 2 can be telescopic, which is composed of multiple sleeves arranged in sequence. In the extended state, the outermost sleeve is located at the top of the middle rod 2, and the innermost sleeve is located at the bottom of the middle rod 2. The outermost sleeve of the middle rod 2 is sleeved with the honeycomb 20 slidingly, and the honeycomb 20 is used for connecting the ribs 3. In the contracted state, the honeycomb 20 is located at the lower end of the outermost sleeve. When the outer force pushes against the umbrella head outer sleeve 10 upward, the umbrella head inner sleeve 11 is gradually retracted into the umbrella head outer sleeve 10, and when the outer force continues to push against the umbrella head outer sleeve 10, the umbrella head inner sleeve 11 and the umbrella head outer sleeve 10 are jointly moved upward to be sleeved outside the honeycomb 20, so as to reduce the total length of the middle rod 2 and the umbrella head structure 1 after contraction.

[0033] Compared with the prior art, the umbrella head structure 1 of the utility model is sleeved on the honeycomb 20 after contraction, so that the total length of the umbrella head structure 1 and the middle rod 2 after contraction is reduced, and the multi-fold umbrella with the umbrella head structure 1 of the utility model has a smaller volume after contraction. It can be understood that the locking member capable of locking the umbrella head inner sleeve 11 from extending out of the umbrella head outer sleeve 10 is arranged in the umbrella head outer sleeve 10, so as to prevent the umbrella head inner sleeve 11 from extending out accidentally. The umbrella head inner sleeve 11 is only unlocked to extend out when the user needs it. The locking member is the prior art, for example, a clamping groove or a buckle, which will not be described here. It can be understood that when the outer force pulls the umbrella head outer sleeve 10 downward, the locking member is unlocked, so that the umbrella head inner sleeve 11 can extend out of the umbrella head outer sleeve 10.

[0034] Further, the innermost umbrella head inner sleeve 11 is horizontally provided with a blocking member 117, the plug rod 103 is sleeved on the bottom of the middle rod 2 through the blocking member 117, and the space from the upper surface of the blocking member 117 to the top of the innermost umbrella head inner sleeve 11 is a containing space 118 for embedding the honeycomb 20. The blocking member 117 is used for blocking the honeycomb 20 from being transitionally retracted into the inner cavity of the innermost umbrella head inner sleeve 11.

[0035] Further, the top end of the honeycomb 20 is outwardly protruded with a resilient second clamping rib 201 in a circumferential direction. The second clamping rib 201 is used for abutting against the lower surface of the second blocking rim 114 of the innermost umbrella head inner sleeve 11 when the innermost umbrella head inner sleeve 11 is sleeved outside the honeycomb 20. Specifically, when the umbrella head outer sleeve 10 is pushed upward under the action of the external force, the umbrella head inner sleeve 11 is gradually retracted into the umbrella head outer sleeve 10, and then the honeycomb 20 enters the innermost umbrella head inner sleeve 11. The second clamping rib 201 abuts against the lower surface of the second blocking rim 114 of the innermost umbrella head inner sleeve 11, so as to prevent the innermost umbrella head inner sleeve 11 from moving downward and leaking out of the honeycomb 20. It can be understood that only when the umbrella head outer sleeve 10 is pulled downward under the action of the external force, the second clamping rib 201 can move upward to be separated from the second blocking rim 114 of the innermost umbrella head inner sleeve 11, so that the honeycomb 20 is separated from the inner cavity of the innermost second umbrella head inner sleeve 112, and the umbrella head outer sleeve 10 and the umbrella head inner sleeve 11 are gradually unfolded.

[0036] Furthermore, an arc-shaped guide surface 115 is formed on the upper surface of the second retaining edge 114 of the innermost umbrella head inner sleeve 11. The guide surface 115 is used to guide the second clamping rib into the inner cavity of the innermost umbrella head inner sleeve 11, so that the second clamping rib 201 can enter the innermost umbrella head inner sleeve 11 more easily.

[0037] Preferably, the first retaining edge 101, the second retaining edge 114, the first clamping rib 113, and the second clamping rib 201 are all annular; the number of the first supporting rib 102 and the second supporting rib 116 is four, and the four first supporting ribs 102 are arranged in a circumferential array on the inner wall of the umbrella head outer sleeve 10 to support the first clamping rib 113 more firmly and prevent the umbrella head inner sleeve 11 from retracting into the umbrella head outer sleeve 10 without the action of external force, and the four second supporting ribs 116 are arranged in a circumferential array on the inner wall of the umbrella head inner sleeve 11 to support the first clamping rib 113 more firmly and prevent the umbrella head inner sleeve 11 from retracting into the umbrella head outer sleeve 10 without the action of external force. A clipping rib 113 provides a more stable support, preventing the inner sleeve 11 of the inner layer of the umbrella head from retracting into the inner sleeve 11 of the outer layer of the umbrella head without the action of external force; the extended ends of the first clipping rib 113, the second clipping rib 201, the first support rib 102 and the second support rib 116 are all arc-shaped surfaces, so that they can cross each other under the action of external force, for example, the first clipping rib 113 moves from outside the first interval to inside the first interval, or the first clipping rib 113 of the inner sleeve 11 of the inner layer of the umbrella head slides out from the second interval of the outer layer of the umbrella head inner sleeve 11.

[0038] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.
