Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic opening and closing umbrella head technology, specifically to an automatic opening and closing umbrella head that is easy to install. Background Technology
[0002] Traditional automatic umbrellas require users to press a button on the umbrella head to automatically close the ribs, while the inner rod is manually compressed. If the inner rod is not fully compressed and the user accidentally releases their hand during manual compression, it can quickly spring open, posing a potential injury hazard.
[0003] To address the aforementioned issues, safe folding structures have been developed. These structures allow the automatic opening and closing umbrella to function properly while preventing the umbrella's central rod from popping out when the user releases their grip. For example, Chinese invention patent publications CN101653309A and CN102138720A disclose a safe folding automatic opening and closing umbrella, both featuring specific umbrella head folding structures that control the umbrella's automatic opening and closing. However, these solutions generate frequent noise during use, negatively impacting the user experience. To solve this noise problem, designers developed a low-noise automatic opening and closing umbrella (patent publication CN217364893U). Through the cooperation of a sliding block body with a movable groove and a ratchet mechanism, the noise level of the entire umbrella head during operation is minimized, significantly improving the user experience.
[0004] However, the designers discovered the following problem during the installation of the aforementioned low-noise automatic opening and closing umbrella: Installing the umbrella head often involves multiple steps. First, the slider body, ratchet, winding wheel, and spring are connected to the umbrella head body, and finally, the outer shell is installed. Since the slider body mainly slides against the umbrella head body by abutting against the inner wall of the outer shell, and the connection between the slider body and the umbrella head body relies solely on a sliding limit shaft and a sliding limit slot, the umbrella head assembly can easily accidentally contact the slider body's contact block during the transfer process before the outer shell is installed. This causes the lower end of the slider body to swing upwards around the sliding limit shaft and separate from the umbrella head body, leading to misalignment of internal components such as the ratchet and moving blocks. Consequently, the slider body needs to be repositioned and reassembled when installing the outer shell, affecting the installation efficiency and quality of the umbrella head.
[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention
[0006] The main purpose of this utility model is to provide an automatic opening and closing umbrella head that is easy to install, which can facilitate the installation of the umbrella head and effectively improve the installation efficiency and quality of the umbrella head.
[0007] To achieve the above objectives, the solution of this utility model is:
[0008] An easy-to-install automatic opening and closing umbrella head includes an umbrella head body and a slider body. The outer side wall of the umbrella head body is provided with a movable surface. The slider body is slidably connected to the movable surface. The side of the movable surface is provided with a snap-fit boss protruding outward. Both sides of the slider body are provided with claws extending towards the umbrella head body. The claws are engaged with the snap-fit bosses. The upper end of the slider body is provided with an abutment force block. The middle part of the slider body is provided with a clearance space.
[0009] Furthermore, the claws are symmetrically arranged on the left and right sides of the slider body, and two claws are distributed vertically on the same side.
[0010] Furthermore, a limiting groove is formed between the upper and lower claws, and a limiting block is provided on the buckle protrusion that slides in cooperation with the limiting groove.
[0011] Furthermore, the umbrella head body has a limiting boss at the upper end of the movable surface.
[0012] Furthermore, the limiting bosses have guide grooves between them, the upper end of the slider body is provided with a connecting block, the abutting force block is provided at the upper end of the connecting block, and the connecting block slides in conjunction with the guide groove.
[0013] Furthermore, the connecting block has a spring receiving groove inside, a spring limiting plate inside the spring receiving groove, and a spring abutment block on the movable surface.
[0014] Furthermore, it also includes a ratchet, a take-up reel, and a spring. The umbrella head body has an internal mounting cavity, and the movable surface has a mounting hole communicating with the mounting cavity. The ratchet has a drive shaft, which is rotatably connected to the mounting hole. The take-up reel and the spring are disposed in the mounting cavity, and the take-up reel and the spring are sleeved on the drive shaft.
[0015] Furthermore, a limiting tooth is provided on the inner sidewall at the lower end of the clearance space.
[0016] Furthermore, it also includes an outer shell, which is fitted over the outside of the umbrella head body.
[0017] Compared with existing technologies, the beneficial effects are:
[0018] 1. This new design simplifies the connection structure between the umbrella head body and the slider body, while retaining the automatic opening and closing function and enhancing the connection strength between the slider body and the umbrella head body.
[0019] 2. In this new design, the slider body is connected to the umbrella head body via a snap-fit mechanism with claws, making the slider body easier to assemble and disassemble, and ensuring a more secure connection. Furthermore, during the transfer process, even without the outer shell installed, the slider body will not separate from the umbrella head body, preventing misalignment or separation of internal parts and significantly improving the assembly efficiency and quality of the umbrella head.

Detailed Implementation
[0026] To further explain the technical solution of this utility model, specific embodiments are described in detail below. It should be noted that the structure of the umbrella head, the umbrella rod, the upper nest, the lower nest, and the umbrella rib device are all existing structures, consistent with those disclosed in Chinese Invention Patent CN101653309A and Chinese Invention Patent CN102138720A, and the principle of opening and closing the umbrella is also the same. Please refer to the announcement texts of the aforementioned invention patents for details; therefore, further detailed descriptions are omitted here. The improvement of this utility model lies in the connection structure between the umbrella head body and the slider body, which will be described in detail below.
[0027] like Figure 1-5As shown, an easy-to-install automatic opening and closing umbrella head includes an umbrella head body 1 and a slider body 2. The outer wall of the umbrella head body 1 has a movable surface 11. The slider body 2 is slidably connected to the movable surface 11. The movable surface 11 has horizontally protruding latching bosses 12 on its left and right sides. The slider body 2 has claws 21 extending towards the umbrella head body 1 on both sides. The claws 21 engage with the latching bosses 12, allowing the slider body 2 to slide up and down tightly against the movable surface 11. The upper end of the slider body 2 has a contact force-bearing block 22, and the middle of the slider body 2 has a clearance space 23. An outer shell 6 is fitted over the umbrella head body 1, and a button is provided on the outer shell 6. During installation, simply align the side of the slider body 2 with the claw 21 towards the movable surface 11, and then push the slider body 2. Since the slider body 2 is made of plastic and the claw 21 has an inclined guide surface, when the slider body 2 is in contact with the movable surface 11, the claw 21 can engage with the snap-fit boss 12, thus restricting the horizontal movement of the slider body 2. Furthermore, the claw 21 and snap-fit boss 12 also guide the slider body 2 during vertical sliding, making the sliding of the slider body 2 smoother. Compared to the traditional shaft-hole sliding connection structure, this invention enhances the connection strength between the slider body 2 and the umbrella head body 1, and improves the service life of this invention. In addition, the installed slider body 2 will not rotate or wobble; even without the outer shell, the slider body 2 will not separate from the umbrella head body 1, preventing misalignment and separation of internal parts of the umbrella head body 1, greatly improving the assembly efficiency and quality of the umbrella head.
[0028] In this embodiment, four claws 21 are specifically provided, symmetrically arranged on the left and right sides of the slider body 2, with two claws 21 distributed vertically on each side. A limiting groove 24 is formed between the vertically arranged claws 21 on the same side, and a limiting block 13 is provided on the latching boss 12 to slide in cooperation with the limiting groove 24. The spacing between the limiting blocks 13 is the same as the width of the slider body 2, allowing the limiting blocks 13 to further limit the slider body 2. Simultaneously, the limiting blocks 13 can guide the slider body 2 as it slides up and down, making the slider body 2 slide more smoothly. Furthermore, the upper surface of the limiting block 13 can also limit the upper claws 21. When the upper claw 21 abuts against the upper surface of the limiting block 13, the slider body 2 stops sliding, preventing the slider body 2 from excessively sliding and separating from the umbrella head body 1.
[0029] In this embodiment, the umbrella head body 1 has a limiting boss 14 at the upper end of the movable surface 11. The limiting boss 14 can limit the upward movement of the slider body 2, and there is a guide groove 15 between the limiting bosses 14. The upper end of the slider body 2 is provided with a connecting block 25, and the abutting force block 22 is provided at the upper end of the connecting block 25. The connecting block 25 slides with the guide groove 15, and the guide groove 15 can limit and guide the connecting block 25.
[0030] In this embodiment, the connecting block 25 has a spring receiving groove 251 inside, a spring limiting plate 252 inside the spring receiving groove 251, a spring abutment block 111 on the movable surface 11, and a spring inside the spring receiving groove 251. The upper end of the spring abuts against the top wall of the spring receiving groove 251, and the lower end of the spring abuts against the lower end of the spring receiving groove 251. The spring limiting plate 252 can prevent the spring from coming out of the spring receiving groove 251. When the slider body 2 moves downward, the spring is compressed, and the spring force can drive the slider body 2 to move upward and reset. During the unidirectional rotation of the ratchet 3, the slider body 2 will be pushed downward, and then the spring force can also drive the slider body 2 to move upward and reset.
[0031] In this invention, a ratchet 3, a take-up reel 4, and a spring 5 are connected to the umbrella head body 1. The umbrella head body 1 has an internal mounting cavity 16, and a mounting hole communicating with the mounting cavity 16 is provided on the movable surface 11. A drive shaft 31 is provided on the ratchet 3, and the drive shaft 31 is rotatably connected to the mounting hole. The take-up reel 4 and the spring 5 are disposed within the mounting cavity 16 and are sleeved on the drive shaft 31. The specific structure of the ratchet 3, the take-up reel 4, and the spring 5 is an existing structure, and its automatic opening and closing driving principle is consistent with the structural principle disclosed in Chinese Utility Model CN217364893U, so it will not be described in detail. The ratchet 3 rotates within the clearance space 23, and a limiting tooth 231 is provided on the inner sidewall of the lower end of the clearance space 23. The limiting tooth 231 can mesh with the teeth on the ratchet 3, thereby limiting and braking the ratchet 3, meaning the ratchet 3 can only rotate in one direction. With the above structure, when the buckle above the slider body 2 contacts the abutting force block 22, the slider body 2 slides downward. During the sliding process, the ratchet 3 separates from the limiting tooth 231. At this time, the ratchet 3 can rotate freely, and the spring in the spring receiving groove 251 is compressed. When the buckle moves upward and separates from the abutting force block 22, the slider body moves upward and resets under the elastic force of the spring, so that the limiting tooth 231 engages with the ratchet 3. At this time, the ratchet 3 can only rotate in one direction.
[0032] 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.
