Description

Technical Field

[0001] This utility model relates to the field of umbrellas, specifically a fluorescent umbrella handle that is convenient for use in dimly lit environments. Background Technology

[0002] Long-handled umbrellas remain popular due to their larger coverage area. These umbrellas have a switch on the hollow shaft at the front of the handle, which allows the canopy to pop forward and unfold when pressed. As commuting needs become more diverse, some umbrellas have begun to use fluorescent handles to improve visibility in dim environments.

[0003] To ensure uniform fluorescence, the shaft and handle of fluorescent long-handled umbrellas are usually bonded together with glue. However, this method only involves the contact area between the inner wall of the handle and the shaft, resulting in a limited bonding area and insufficient adhesive force. Furthermore, when the umbrella is opened, the shaft applies axial elastic force to the handle, which can easily cause the connection to detach due to frequent opening and closing after prolonged use. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a fluorescent umbrella handle suitable for use in dimly lit environments. The structure includes an umbrella handle body for mounting a hollow umbrella shaft. The umbrella handle body has a fluorescent layer. A countersunk cavity at the top of the umbrella handle body allows the umbrella shaft to be inserted. An adhesive layer is provided between the umbrella handle body and the umbrella shaft. A central island is located at the bottom of the central island, extending upwards from the bottom of the central island. The adhesive layer includes an outer adhesive layer and an inner adhesive layer. The outer adhesive layer is located between the inner wall of the central island and the umbrella shaft, while the inner adhesive layer is attached to the central island and located between the central island and the inner wall of the umbrella shaft. An inner blocking element is mounted at the top of the central island. The inner blocking element has a large-diameter portion with a diameter larger than the diameter of the portion where the bottom of the inner blocking element connects to the central island. The inner adhesive layer covering the central island extends to the large-diameter portion of the inner blocking element.

[0005] Furthermore, the diameter of the bottom end of the central island is smaller than the inner diameter of the umbrella pole, and the diameter of the top end of the central island is smaller than the diameter of the bottom end of the central island.

[0006] Furthermore, the top of the central island is provided with a countersunk connecting hole, the diameter of the top of the connecting hole being larger than the diameter of the bottom of the connecting hole, and the internal resistance component is installed onto the central island through the connecting hole.

[0007] Furthermore, the internal resistance element is screw-shaped, the large-diameter portion is located at the top of the internal resistance element and is set as a side edge, and the inner adhesive layer covers the side edge of the screw-shaped internal resistance element; the inner wall of the connecting hole is smooth, and the internal resistance element is screwed into the connecting hole by threads to engage with the inner wall of the connecting hole.

[0008] Furthermore, the diameter of the side edge is greater than the diameter of the top of the central island and less than or equal to the diameter of the bottom of the central island.

[0009] Furthermore, a diameter reduction groove is provided on the inner resistance element below the side edge. The diameter of the diameter reduction groove is smaller than the diameter of the threaded portion on the inner resistance element, and the inner adhesive layer covers the diameter reduction groove.

[0010] Furthermore, a fastener is engaged within the reduced diameter groove. The fastener includes a fastening plate and several engagement teeth arranged around the side end of the fastening plate. The distance between the outer end of the engagement teeth and the axis of the inner resistance element is greater than the inner diameter of the umbrella rod. The engagement teeth are inclined on the fastening plate and tilt downward at the connection between the engagement teeth and the fastening plate. The side end of the fastening plate is provided with an opening groove pointing to the center of the fastening plate. The fastening plate is laterally engaged with the reduced diameter groove through the opening groove.

[0011] Furthermore, the inclined engagement teeth are twisted on the buckle plate, and the engagement teeth are twisted around their own length direction so that the outer ends of the engagement teeth are inclined; the reduced diameter groove has at least two vertical planes, and the opening groove engages with the vertical planes of the reduced diameter groove to restrict the degree of freedom of the buckle to rotate around the axis of the inner resistance element.

[0012] Furthermore, the inclination direction of the outer end of the biting tooth is the same as the inclination direction of the thread of the internal resistance element.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a central island in the middle of the inner cavity, allowing the adhesive to adhere to the island. A section is created on the inner side of the umbrella shaft by the large-diameter portion of the inner stopper, allowing the adhesive adhering to the central island to fill this area, forming a more stable inner adhesive layer that contacts the inner side of the umbrella shaft. This also restricts the range of motion of the adhesive, making the connection between the umbrella shaft and the main body of the umbrella handle more stable and secure.

[0015] Furthermore, this invention incorporates a buckle on the internal resistance component, which engages with the embedded umbrella shaft, restricting its freedom to detach. The buckle's side engagement teeth are inclined in a spiral shape, allowing the umbrella shaft to move downwards along the engagement teeth by rotating it during installation, thus making the connection more secure.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0025] Examples, such as Figures 1-6 As shown: This utility model provides a fluorescent umbrella handle that is convenient for use in dim environments. Its structure includes an umbrella handle body for mounting a hollow umbrella shaft. The umbrella handle body is provided with a fluorescent layer. The umbrella handle body is usually injection molded. Therefore, in this embodiment, the umbrella handle body is made of a fluorescent layer material throughout. It adopts the form of photoluminescent energy storage. After being irradiated by natural light, fluorescent light, ultraviolet light, etc., it stores light energy. After the light irradiation stops, it slowly releases it in the form of fluorescence, so that the umbrella handle body can be used conveniently in dim environments. The top of the umbrella handle body is provided with a countersunk cavity for inserting the umbrella shaft. The side wall of the cavity is smooth. An adhesive layer is provided between the umbrella handle body and the umbrella shaft. The adhesive layer includes an outer adhesive layer and the outer adhesive layer is located between the inner wall of the cavity and the umbrella shaft, so as to ensure that the contact surface with the umbrella shaft is smooth, so that the fluorescence appears smooth in the visual effect of the upper and lower parts.

[0026] In this embodiment, a central island is provided at the bottom of the inner cavity, extending upward from the bottom of the inner cavity. A side bottom is also provided at the bottom edge of the central island and the bottom of the inner cavity. The bottom of the umbrella shaft contacts the side bottom. The adhesive layer also includes an inner adhesive layer, which is attached to the central island and located between the central island and the inner wall of the umbrella shaft. At the same time, an inner blocking member is installed at the top of the central island. The inner blocking member has a large diameter portion with a diameter larger than the diameter of the portion where the bottom end of the inner blocking member connects to the central island. The inner adhesive layer covering the central island covers the large diameter portion of the inner blocking member. The large diameter portion of the inner blocking member separates a section downward on the inner side of the umbrella shaft, allowing the adhesive to fill it to form a more stable inner adhesive layer for contact with the inner side of the umbrella shaft. It also limits the range of motion of the adhesive, making the connection of the umbrella shaft more stable.

[0027] It should be noted that the diameter of the bottom of the central island is smaller than the inner diameter of the umbrella shaft, and the diameter of the top of the central island is smaller than the diameter of the bottom of the central island, thus forming a frustum shape to facilitate demolding during production.

[0028] Furthermore, the top of the central island is provided with a countersunk connecting hole. To facilitate demolding, the diameter of the top of the connecting hole is larger than the diameter of the bottom of the connecting hole. The internal resistance component is installed onto the central island through the connecting hole. In this embodiment, the internal resistance component is screw-shaped, with the large-diameter part located at the top of the screw-shaped internal resistance component and serving as a side edge. The inner adhesive layer covers the side edge of the screw-shaped internal resistance component, and the inner wall of the connecting hole is smooth. The internal resistance component is screwed into the connecting hole by threads and engages with the inner wall of the connecting hole, thus eliminating the need to form threads during injection molding. By screwing the screw into the connecting hole, it can be connected and secured to the connecting hole through extrusion and shearing.

[0029] It should be noted that the diameter of the side edge is greater than the diameter of the top of the central island and less than or equal to the diameter of the bottom of the central island. Furthermore, the inner resistance component below the side edge is provided with a reduction groove. The diameter of the reduction groove is smaller than the diameter of the threaded portion on the inner resistance component. The inner adhesive layer covers the reduction groove to further engage with the inner resistance component. After the adhesive dries, the screw-shaped inner resistance component, which is subjected to force, tends to come off by rotating its threads.

[0030] Furthermore, a fastener is engaged within the reduced diameter groove. The fastener includes a fastener plate and several engagement teeth arranged around the side of the fastener plate. The distance between the outer end of the engagement teeth and the axis of the inner blocking element is greater than the inner diameter of the umbrella rod. The side of the fastener plate is provided with an opening groove pointing towards the center of the fastener plate. The fastener plate is laterally engaged with the reduced diameter groove through the opening groove. It should be noted that the engagement teeth are inclined on the fastener plate and tilt downwards at the connection between the engagement teeth and the fastener plate.

[0031] In this embodiment, the inclined biting teeth are twisted on the buckle plate. The biting teeth twist around their own length direction so that the outer ends of the biting teeth are inclined. This can be regarded as the outer side of the inner resistance element having a spiral line with the axis of the inner resistance element as the center line, and the outer ends of the biting teeth are located on the spiral line. At the same time, the diameter reduction groove has at least two vertical planes. The opening groove and the vertical plane of the diameter reduction groove engage to restrict the degree of freedom of the buckle to rotate around the axis of the inner resistance element. This allows the umbrella rod to rotate the handle when it is embedded in the handle body and abuts against the buckle, so that the handle can be rotated to make the handle go deeper into the spiral direction on the outside of the buckle. Furthermore, the inclination direction of the outer ends of the biting teeth is the same as the inclination direction of the thread of the inner resistance element, thereby engaging more tightly with the handle body.

[0032] Therefore, in specific implementation, the umbrella handle body is molded by injection molding, and then the buckle is fastened into the reduced diameter groove of the inner resistance component through the opening groove. The inner resistance component is screwed into the connecting hole of the central island with a screwdriver, and a certain distance is maintained between the buckle and the central island at the bottom. This distance is set according to the actual needs of those skilled in the art. Then, glue is poured into the bottom of the inner cavity of the umbrella handle body, and glue is applied to the outside of the umbrella shaft. Then, the umbrella shaft is inserted into the inner cavity and the buckle is inserted downward to the side bottom. Then, the handle is rotated so that the handle goes down into the side bottom along the spiral direction of the buckle. After the glue dries, an inner adhesive layer is formed on the inside of the umbrella shaft and an outer adhesive layer is formed between the umbrella shaft and the umbrella handle body, so that the connection between the umbrella shaft and the umbrella handle body is more stable.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
