Description

Technical Field

[0001] This utility model relates to the field of folding umbrella technology, and in particular to an umbrella head structure. Background Technology

[0002] Umbrellas are common tools for protecting against rain and sun. Existing umbrellas mainly consist of a central pole, upper canopy, lower canopy, umbrella opening seat, and umbrella ribs. The upper and lower canopies are installed at the upper and lower ends of the central pole, respectively. The lower canopy moves up and down with the central pole to open and close the umbrella ribs. The umbrella opening seat is installed at the lower end of the lower canopy and has a button on it to control the opening and closing of the umbrella. There is a movable gap between the inner wall of the lower end of the umbrella opening seat (outside the button) and the outer wall of the central pole. The umbrella ribs have foldable upper main ribs, lower main ribs, and branch ribs. The upper end of the upper main rib is hinged to the upper canopy, the lower end of the upper main rib is hinged to the middle of the lower main rib, the lower end of the lower main rib is hinged to the lower canopy, and the upper end of the lower main rib is hinged to the upper end of the branch rib. The lower end of the central pole has an umbrella tip for gripping. Umbrellas with this type of structure often have a very short and small canopy, such as a round shape, to make them easier to carry and shorten their overall length. This way, the umbrella won't appear too long when folded. However, the short and small canopy design makes it difficult for the user to grip. If the canopy has a straight handle, the umbrella will be too long when folded, making it inconvenient to store and carry.

[0003] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0004] The purpose of this invention is to provide an umbrella head structure to solve the problem that the umbrella head of existing umbrellas cannot be matched with umbrellas of different sizes.

[0005] To achieve its purpose, this utility model adopts the following technical solution:

[0006] An umbrella head structure includes an umbrella head mounted on the lower end of a central pole; the umbrella head includes a handle body and a detachable connecting block. The handle body has a grip section and a head located below the grip section. The grip section is a hollow shell with open ends that can accommodate the switch base and the lower end of the lower main rib of the umbrella. The detachable connecting block is confined within the grip section, and the grip section and the detachable connecting block are provided with a limiting structure to limit the circumferential rotation of the detachable connecting block. The head is located outside one end of the grip section and closes the port of the grip section. The detachable connecting block and the head are provided with a detachable mounting structure that allows the detachable connecting block and the head to be detachably connected. The detachable connecting block is provided with a connecting structure that is detachably connected to the lower end of the central pole. The end of the detachable connecting block facing away from the head has a protruding limiting storage block that can extend into the movable gap between the switch base and the central pole and can be confined within the movable gap between the switch base and the central pole.

[0007] The grip section has a strip-shaped structure that runs vertically through the grip section. The lower end of the grip section is provided with a limiting block that blocks the opening at the lower end of the grip section. The limiting block has a through opening that runs vertically through the grip section. The disassembly connecting block is vertically positioned inside the grip section, and the lower end of the disassembly connecting block passes through the through opening and extends out of the bottom surface of the grip section to be disassembled and connected to the head. The upper outer wall of the disassembly connecting block is provided with a stacking plate that overlaps on the top surface of the limiting block. The hollow cavity of the grip section, the space above the stacking plate, is a receiving space for the umbrella's switch base and the lower end of the lower main rib.

[0008] The disassembly connecting block is a cylindrical structure. The outer side wall of the disassembly connecting block has two oppositely arranged outer cutting planes. The inner side wall of the opening has an inner cutting plane that is attached to the outer cutting plane at the position corresponding to the outer cutting plane. The outer cutting plane and the inner cutting plane constitute the above-mentioned limiting structure.

[0009] The outer side wall of the disassembly connecting block extending beyond the bottom surface of the gripping section is provided with external threads. The head is a hollow block with an open top surface, and the inner side wall of the head is provided with internal threads that are screwed together with the external threads. The internal threads and external threads constitute the above-mentioned disassembly and installation structure.

[0010] The top surface of the disassembly connecting block is recessed with an insert groove into which the lower end of the central rod is embedded. A fixing hole is provided on the outer side wall of the disassembly connecting block. The fixing hole passes through the disassembly connecting block laterally and through the insert groove. The disassembly connecting block is connected to the central rod by a fixing rod passing through the fixing hole and the central rod. The insert groove, fixing hole and fixing rod constitute the connecting structure.

[0011] The top surface of the disassembly connecting block is provided with a number of protrusions spaced apart along the circumferential direction of the mounting groove. Each protrusion forms a circular structure and can extend into the aforementioned limiting and receiving block within the movable gap between the switch base and the central rod.

[0012] The upper outer wall of the protrusion is provided with an arc-shaped protrusion ring that is consistent with the extension direction of the protrusion, and the top surface of the arc-shaped protrusion ring and the outer wall of the arc-shaped protrusion ring are connected by an arc transition through the arc surface.

[0013] The bottom surface of the grip section has a protruding ring with a closed-loop structure, and the top surface of the head has a recess with a closed-loop structure corresponding to the position of the protruding ring.

[0014] In this novel umbrella head structure, the lower end of the central rod is fixed to the lower end of the central rod using a connecting structure. The connecting block is then inserted vertically into the grip section from top to bottom through the top opening, with its lower end extending beyond the bottom surface of the grip section. The head is then mounted on the lower end of the connecting block and positioned below the grip section via a disassembly and installation structure, thus completing the connection between the umbrella head and the central rod. Finally, the central rod is retracted upwards, allowing the limiting and retracting block to be stored within the movable gap between the switch base and the central rod. The switch base and the lower end of the lower main rib of the umbrella then enter the grip section, resulting in a shorter overall retracted length of the umbrella head. Compared with existing technologies, the grip section is more convenient to hold during use, and the switch base and the lower end of the main rib can enter the grip section, allowing the umbrella head to be inserted into the folded umbrella. This achieves the storage and concealment of the grip section, shortening the length of the umbrella head exposed outside the ribs, thereby shortening the overall length of the umbrella when folded. As a result, the overall length of the umbrella after folding is shorter, making it easier to store and carry. Furthermore, when folded, the limiting storage block can enter the movable gap, which can further shorten the length of the umbrella when folded. At the same time, the limiting structure makes it difficult for the disassembly connecting block to move circumferentially, making it easier for the head to be installed on the disassembly connecting block.

[0017] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0018] A type of umbrella head structure, such as Figures 1-2As shown, the umbrella includes an umbrella head mounted on the lower end of the central rod. The umbrella head includes a handle body and a detachable connecting block 1. The handle body has a grip section 2 and a head 3 located below the grip section 2. The grip section 2 is a hollow shell with open ends, allowing the umbrella's switch seat and the lower end of the lower main rib to be housed within it. The detachable connecting block 1 is confined within the grip section 2. Specifically, the grip section 2 has a vertically penetrating strip-shaped column structure. A limiting block 21 is provided inside the lower end of the grip section 2 to block the open opening at the lower end of the grip section 2. The grip section 2 has a through-hole 100 at the top. The disassembly connecting block 1 stands upright inside the grip section 2, with its lower end passing through the through-hole 100 and extending beyond the bottom surface of the grip section 2. The inner shape of the through-hole matches the outer shape of the disassembly connecting block 1. A pressing plate 11 protrudes from the outer wall of the upper end of the disassembly connecting block 1, overlapping the top surface of the limiting block 21. The hollow cavity of the grip section 2, above the pressing plate 11, serves as a space for accommodating the umbrella's switch base and the lower end of the lower main rib. In use, the lower end of the disassembly connecting block extends vertically out of the through-hole 100, and is prevented from detaching from the lower end of the grip section 2 by the pressing plate 11 and the limiting block 21.

[0019] The gripping section 2 and the disassembly connecting block 1 are provided with a limiting structure to limit the circumferential rotation of the disassembly connecting block 1. The head 3 is located outside one end of the gripping section 2 and closes the port of the gripping section 2. The disassembly connecting block 1 and the head 3 are provided with a disassembly and installation structure that allows the disassembly connecting block 1 and the head to be disassembled and connected. Specifically, the disassembly connecting block 1 is a cylindrical structure. The outer side wall of the disassembly connecting block 1 is provided with two oppositely arranged outer cutting planes 41. The inner side wall of the through 100 is provided with an inner cutting plane 42 that is attached to the outer cutting plane 41 at the position corresponding to the position of the outer cutting plane 41. The outer cutting plane 41 and the inner cutting plane 42 constitute the above-mentioned limiting structure. The outer side wall of the disassembly connecting block 1 that extends out of the bottom surface of the gripping section 2 is provided with an external thread. The head 3 is a hollow block with an open top surface. The inner side wall of the head 3 is provided with an internal thread that is screwed together with the external thread. The internal thread and the external thread constitute the above-mentioned disassembly and installation structure. In application, align the lower end of the disassembly connecting block 1 with the open top surface of the head 3. Use the internal thread of the head 3 and the external thread of the disassembly connecting block 1 to screw the head 3 and the lower end of the disassembly connecting block 1 together. Due to the setting of the outer cutting plane 41 and the inner cutting plane 42, the disassembly connecting block 1 will not move circumferentially during the screwing process of the head 3 and the disassembly connecting block 1, which facilitates the screwing of the head 3 and the disassembly connecting block 1. After the head 3 and the disassembly connecting block 1 are screwed together and installed, the top surface of the head 1 fits against the bottom surface of the grip section 2, and the outer side wall of the head 3 smoothly transitions with the outer side wall of the grip section 2, thus completing the connection between the disassembly connecting block 1 and the grip body.

[0020] The disassembly connecting block 1 is provided with a connecting structure for disassembly and connection to the lower end of the middle rod. The top surface of the disassembly connecting block 1 is recessed with an insert groove for the lower end of the middle rod to be embedded in. The lower end of the middle rod is square in shape. The outer wall of the lower end of the middle rod is recessed with a clamping groove. The insert groove is correspondingly square in shape. The two inner groove walls opposite to the insert groove are provided with clamping blocks 12 embedded in the clamping groove. The outer dimensions of the middle rod match the inner diameter of the insert groove. The outer wall of the disassembly connecting block 1 is provided with a fixing hole 200 that passes through the disassembly connecting block 1 and through the insert groove. The lower end of the middle rod is provided with an inner fixing hole that passes through the middle rod at the position corresponding to the fixing hole 200. The disassembly connecting block is locked together with the middle rod by a fixing rod passing through the fixing hole and the inner fixing hole. The insert groove, fixing hole and fixing rod are the connecting structure. In application, the lower end of the central rod extends into the mounting groove, aligning the fixing hole 200 with the inner fixing hole. A fixing rod passes through both the fixing hole 200 and the inner fixing hole, preventing the central rod from detaching from the mounting groove. Furthermore, the central rod is detachably connected to the disassembly connecting block 1, allowing the umbrella head to be used with central rods of different sizes. When using central rods of different sizes, only the disassembly connecting block 1 with a mounting groove matching the size of the central rod needs to be replaced; the entire umbrella head does not need to be replaced, thus broadening its applicability.

[0021] The disassembly connecting block 1 has a limiting and receiving block 5 protruding from one end opposite to the head 3, which can extend into and be confined within the movable gap. Specifically, the top surface of the disassembly connecting block 1 has several protrusions spaced along the circumferential direction of the mounting groove. Each protrusion forms a circular space that can extend into the limiting and receiving block 5 within the movable gap between the switch base and the central rod. The maximum outer diameter of the circular space formed by each protrusion matches the inner wall of the switch base. In application, the central rod retracts upward, and each protrusion moves upward. Under the action of the inner wall of the switch base, each protrusion can move towards the center of the mounting groove, facilitating its entry into the movable gap. After entering the movable gap, each protrusion releases and is locked within the movable gap.

[0022] In this novel umbrella head structure, the lower end of the central rod is inserted into the corresponding mounting groove. A connecting structure is used to fix the disassembly connecting block 1 to the lower end of the central rod. Then, the disassembly connecting block 1 is vertically inserted into the gripping section 2 from top to bottom through the top opening. The overlapping plate 11 is stacked on the top surface of the limiting block 21. The upper end of the disassembly connecting block 1 is limited within the gripping section 2, and the lower end of the disassembly connecting block 1 extends beyond the bottom surface of the gripping section 2. The lower end of the disassembly connecting block 1 is then inserted into the top opening of the head, and finally, an internal screw is used... The combination of the thread and the external thread allows the head 3 to be screwed onto the lower end of the disassembly connecting block 1 and positioned below the grip section 2. At the same time, the limiting structure prevents the disassembly connecting block 1 from moving circumferentially, making it easier for the head 3 to be screwed onto the disassembly connecting block. The head 3 is screwed onto the disassembly connecting block until the top surface of the head 3 contacts the bottom surface of the grip section 2, thus completing the connection between the umbrella head and the center rod. Finally, the center rod is retracted upwards, allowing the limiting storage block 5 to be stored within the movable gap between the switch seat and the center rod. The switch seat of the umbrella and the lower end of the lower main rib enter the accommodating space of the grip section 2, resulting in a shorter overall storage length for the umbrella head. Compared with existing technologies, the strip-shaped grip section 2 is easier to hold during use. Moreover, the umbrella's switch base and the lower end of the main rib can enter the grip section 2, allowing the umbrella head to be inserted into the folded umbrella, thus achieving the storage and concealment of the grip section 2 and shortening the length of the umbrella head exposed outside the umbrella ribs. This shortens the overall length of the umbrella when folded, making it easier to store and carry. Furthermore, when folded, the limiting storage block 5 enters the movable gap, which can further shorten the length of the umbrella when folded.

[0023] In this invention, preferably, the upper outer side wall of the protrusion is provided with an arc-shaped protrusion ring 51 that is consistent with the extension direction of the protrusion, and the top surface of the arc-shaped protrusion ring 51 and the outer side wall of the arc-shaped protrusion ring are connected by an arc transition through the arc surface 511. The lower inner side wall of the switch base is provided with a limiting protrusion ring with a closed-loop structure. In application, the middle rod retracts upward, the arc surface and the limiting protrusion ring are pressed against each other, and each protrusion is pressed against each other, so that each protrusion passes through the limiting protrusion ring to reset in the switch base and is limited in the switch base.

[0024] In this invention, the bottom surface of the gripping section 2 is provided with a protruding ring 22 in a closed-loop structure, and the top surface of the head 3 is provided with a recess in a closed-loop structure at the position corresponding to the protruding ring 22; in application, the protruding ring 22 extends into the recess, making the connection between the head 3 and the gripping section 2 more secure.

[0025] In this novel design, the bottom surface of the head 3 has a downward-convex arc structure. The outer diameter of the head gradually decreases from bottom to top, and the outer diameter of the grip section 2 gradually decreases from bottom to top to the middle of the grip section 2. Furthermore, the outer diameter of the grip section 2 gradually expands from the middle of the grip section 2 from bottom to top, and the outer wall of the head and the outer wall of the grip section 2 are connected in an arc-shaped transition. This grip body structure creates an arc-shaped structure on the outer wall of the grip body that facilitates user gripping, resulting in better comfort during gripping.

[0026] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
