Description

Technical Field

[0001] A connecting device for a chemical fluorescent stick. Background Technology

[0002] The most common type of chemical glow stick is the thin, rod-shaped variety, typically with a length-to-diameter ratio between 100:1 and 10:1. For example, a fluorescent necklace is usually a slender rod with a diameter of 6mm and a length of 600mm; the most common is a fluorescent bracelet with a length of 200mm and a diameter of 5mm. There are also some irregularly shaped products, such as a flat, wide glow stick that is 15mm wide, 5mm thick, and 210mm long. These glow sticks contain one or more slender ampoules encapsulating a single-component liquid that produces a binary fluorescent reaction. When the plastic tube is bent, causing the ampoule to break, the released component reacts with the other component encapsulated inside the plastic tube, producing chemiluminescence. Because of the shape limitations of the glass ampoule, glow sticks are manufactured straight; a slight bend at the user's hand will break the ampoule and cause them to glow. To obtain a circular shape like a bracelet, the two ends of the plastic tube must be connected. The simplest connector is a small tube; the glow stick is bent into a circle, and the two ends are inserted into the ends of the small tube, thus creating a bracelet-like glow stick ring. Multiple glow sticks can also be connected to form a large circle via small tubes. CN2554944Y discloses an "8"-shaped connector that uses double holes through the "8" to create a spiral-shaped ring. CN211676303U, CN219533557U, CN305248697S, and CN300810328D also disclose various connecting devices for self-connection or interconnection of multiple glow sticks, all of which use friction to fix the ends of the glow stick or the surface of the tube. However, all of these connecting devices share a common problem: when connecting the ends of the glow stick to form a ring, it is usually impossible to insert them into the connecting device with one hand. This is especially true for bracelet-type products, because if the operator inserts them into a ring with both hands, some users with large hands will not be able to wear them on their wrists. There is a particular need for a connecting device that can be operated with one hand to connect the ends of the glow stick to form a ring shape. Another issue with connecting the aforementioned wide, flat fluorescent bracelets using tubular connectors is that the thick, resilient material of the bracelets requires significant friction to connect them to the connectors. This necessitates considerable force to insert both ends of the bracelet into the tubular connectors, and the bracelets often spring back. Since glow sticks are primarily toys used by children, ensuring an easy, circular connection is crucial. Furthermore, the high elasticity of the glow sticks makes the tubular connectors susceptible to bending forces, potentially causing them to break and transform from a circular shape into a pear shape, affecting the overall appearance.

[0003] This invention provides a separate connecting device. During production, the holes on the connecting device are first inserted into both ends of the glow stick. When the user uses the device, they only need to connect the connectors on the connecting devices at both ends of the glow stick, thus easily completing the circular connection of the glow stick. Summary of the Invention

[0004] A connecting device, characterized in that: the connecting device includes two parts, A part 1 and B part 2, wherein A part 1 is provided with connector 3 and glow stick socket 5, and B part 2 is provided with connector 4 and glow stick socket 5', and connector 3 and connector 4 can be connected to or separated from each other.

[0005] The aforementioned connecting device is characterized in that: connector 3 has a hollowed-out locking slot, and connector 4 has a fishbone-shaped barb, the hollowed-out locking slot and the fishbone-shaped barb can be connected or separated by each other.

[0006] The aforementioned connecting device is characterized in that: connector 3 and connector 4 each have two hooks, and the two hooks can cooperate to hook and connect or separate.

[0007] The aforementioned connecting device is characterized in that: connector 3 is a mushroom-shaped protrusion, connector 4 is a recess with a narrowed opening, and the mushroom-shaped protrusion and the recess with a narrowed opening can be inserted into or separated from each other.

[0008] The aforementioned connecting device is characterized in that: the first fluorescent stick insertion hole 5 and the second fluorescent stick insertion hole 5' are equipped with friction ribs 6.

[0009] The aforementioned connecting device is characterized in that: after connector 3 and connector 4 are connected, they form an arc-shaped whole.

[0010] Manufacturers can use the above-mentioned connecting device to first insert the two parts A, part 1 and B, 2 of the connecting device into the two ends of the glow stick with a large force using pressure machinery during processing, so that they can obtain a large frictional force with the glow stick to fix them before leaving the factory. When delivering it to the user, the user only needs to bend the glow stick to start it, and then use one hand to bend the glow stick to push the two connectors 1 3 and connector 2 4 to easily complete the action of the connecting clip or hook, so that the glow stick can complete the ring closure.

[0012] Figure 2 A schematic diagram showing the connection status with a glow stick inserted into the connecting device.

[0013] Figure 3 This is a cross-sectional view of the connecting device in the hook-and-loop connection state.

[0014] Figure 4 The connector for the connecting device is a schematic diagram with double mushroom-shaped protrusions. Implementation

[0015] Figure 1 This diagram illustrates the separated state of the connecting device. The two separated parts are: 1, connecting device A, and 2, connecting device B. Part A (1) has a glow stick insertion hole 5 at one end and a connector 3 with a perforated locking slot at the other end. Part B (2) has a flexible, fishbone-shaped barbed connector 4 at one end and a glow stick insertion hole 5' at the other end. Connecting device A and connecting device B form a pair of snap-fit ​​fasteners. When the fishbone-shaped barbed connector 4 is inserted into the connector 3 with the perforated locking slot, they can lock together. Pressing the sides of the flexible, fishbone-shaped barbed connector 4 can disengage it from the locking slot of the connector 3, separating them. To increase friction, friction ridges 6 are provided in the glow stick insertion holes 5 and 5' to increase friction when the glow stick is inserted.

[0016] Figure 2 A schematic diagram showing the connection status with a glow stick inserted into the connecting device.

[0017] In the figure, 7 is a flat, wide strip of glow stick. Its two ends are inserted into the glow stick sockets on both sides of the connecting device A and the connecting device B, respectively. The connecting device A and the connecting device B form a pair of male and female snap fasteners. The fishbone-shaped barbed connector 2 4 is inserted into the connector 1 3 with a hollowed-out slot so that they are locked together and connected, thus forming a ring shape with the flat, wide strip of glow stick 7.

[0018] In practical use, first, insert the two parts of the connecting device, A part 1 and B part 2, into the two ends of the glow stick 7 with considerable force to create a large frictional force and secure them. The user only needs to bend and activate the glow stick 7, then easily push the two connecting devices A and B by bending the glow stick 7 with one hand, allowing the fishbone-shaped barbed connector 2 4 to insert into the connector 1 3 with the hollowed-out locking slot, so that they lock together and the glow stick 7 completes the circular closure. From the side view of the connecting device after the connection is locked, it can also be seen that when connector 1 3 and connector 2 4 are connected, they form an arc-shaped whole. This pre-bent arc can reduce the force of the glow stick 7 springing back, making the connecting device less prone to bending and deformation, while making the ring more perfect and easier to operate during insertion.

[0019] Figure 3 This is a cross-sectional view of the connecting device in the hook-and-loop connection state.

[0020] In the figure, 1 is the connecting device A and 2 is the connecting device B. Part A 1 has a glow stick socket 5 at one end and a hook connector 4 at the other end. Part B 2 has a hook connector 3 at one end and a glow stick socket 5' at the other end. From the cross-sectional view AA, it can be seen that the hook connector 3 and the hook connector 4 of connecting device A and connecting device B form a pair of hook-and-lock mechanisms that connect them to each other in a hook-and-lock manner.

[0021] Figure 4 A schematic diagram of a connector for a connecting device with double mushroom-shaped protrusions.

[0022] In the diagram, 1 represents connecting device A, and 2 represents connecting device B. Part A (1) has a glow stick insertion hole 5 at one end, and a pair of mushroom-shaped protruding connectors 3 at the other end, distributed on the extension handle of the glow stick insertion hole 5. Part B (2) has a glow stick insertion hole 5' at one end, and a pair of concave-opening connectors 4 are distributed on the extension handle of the insertion hole 5'. The mushroom-shaped protruding connectors 3 and the concave-opening connectors 4 are dimensionally corresponding, with the outer diameter of the mushroom-shaped protrusions and the inner diameter of the concave-opening recesses being tightly fitted. When both ends of the glow stick are inserted into the glow stick insertion holes 5 and 5' of connecting devices A and B respectively, bending the glow stick brings connecting devices A and B closer together, squeezing the pair of mushroom-shaped protruding connectors 3 into the two concave-opening connectors 4 to complete the connection, forming a ring shape with the glow stick. This connecting device is suitable for small-diameter cylindrical glow sticks.

[0023] In the above embodiments, the mushroom-shaped protrusion connector 3 can also be a single unit. It is positioned on the top of the other end of the glow stick insertion hole 5 of the glow stick connecting device A along the axial direction of the connecting device. Similarly, the single recessed connector 4 with a narrowed opening is positioned on the top of the other end of the glow stick insertion hole 5' of the glow stick connecting device B. This pair of mushroom-shaped protrusions and the narrowed opening recess are connected and inserted. Such a connecting device can also easily complete the ring connection of glow sticks, but the connection force provided is relatively small, which is suitable for small-diameter round glow stick products.

[0024] The above embodiments are merely illustrative examples and do not limit the scope of this invention. Similar connection schemes can achieve the purpose of easily connecting glow sticks into a ring, and are all within the protection scope of this application.
