Additionally, the embodiments described below are merely some embodiments of this application, and not all embodiments.

[0022] The cylindrical rod-shaped lamp tube mainly consists of a light source 12 and a protective shell 11, with the light source 12 housed within the cylindrical protective shell 11. The lamp tube can be considered a linear light source with a wide illumination range and good illumination effect, suitable for use in various scenarios. Typically, to facilitate lamp tube production and transportation, the length of the lamp tube is controlled within a reasonable range. However, when illuminating a larger area, multiple shorter lamp tubes can be connected end-to-end, with adjacent lamp tubes primarily connected by a connecting device. However, existing connecting devices are not only structurally complex and unreliable during connection, but also cumbersome to operate and inconvenient to use.

[0023] To address the aforementioned technical issues as much as possible, see [link / reference]. Figures 1 to 7 , Figure 11 In one embodiment of this application, a lamp tube connection device is provided, comprising: a connecting seat 2, a rotating locking cover 3, and a connecting pin 4. The connecting seat 2 has a first end face and a second end face for connecting with a lamp tube 1. The second end face is provided with an annular groove 21 and a first connecting hole 22. The lamp tube 1 includes a light source 12 and a protective shell 11. The light source 12 is disposed inside the protective shell 11 along the central axis direction. The connecting seat 2 can be connected to the end of the lamp tube 1 and is connected to the protective shell 11. The connecting seat 2 can seal the end of the lamp tube 1, effectively improving the protective effect of the lamp tube 1.

[0024] The rotating cover 3 includes a ring wall 31 and a connecting part 32. The connecting part 32 is disposed on the ring wall 31, and the ring wall 31 is provided with a connecting structure 33. The connecting structure 33 is connected to the slide groove 21, and the connecting part 32 is provided with a second connecting hole 321. The rotating cover 3 is connected to the second end face of the connecting seat 2, and the connecting structure 33 is fitted into the slide groove 21. The central axis of the rotating cover 3 is approximately coincident with the central axis of the connecting seat 2, and the rotating cover 3 can rotate relative to the connecting seat 2.

[0025] The diameter of the ring wall 31 is equal to or slightly larger than the diameter of the connecting seat 2. When the rotating lock cover 3 is connected to the connecting seat 2, the rotating lock cover 3 and the connecting seat 2 are arranged in upper and lower layers. Alternatively, at least part of the connecting seat 2 is embedded inside the ring wall 31 of the rotating lock cover 3. The inner wall surface of the ring wall 31 has a gap with the outer wall of the connecting seat 2 or is in contact with it.

[0026] See Figure 9 and Figure 10 The connecting pin 4 has a connecting section 41 and connectors 42 at both ends of the connecting section 41. The rotating cover 3 can rotate relative to the connecting seat 2 to switch between a locked state and an unlocked state; when the rotating cover 3 is in the unlocked state, the first connecting hole 22 and the second connecting hole 321 are aligned, and the connector 42 at one end of the connecting pin 4 can pass through the second connecting hole 321 and connect to the first connecting hole 22; when the rotating cover 3 is in the locked state, the first connecting hole 22 and the second connecting hole 321 are misaligned, and the connecting part 32 locks the connector 42 connected to the first connecting hole 22.

[0027] like Figure 4 As shown, after the rotating locking cover 3 and the connecting seat 2 are connected and combined, a connecting assembly 10 can be formed. This connecting assembly 10 can be respectively set at both ends of the lamp tube 1 and tightly connected to the protective shell 11 of the lamp tube 1. When it is necessary to connect two lamp tubes 1 together, the connector 42 at the first end of the connecting pin 4 is inserted into the connecting assembly at the first end of the first lamp tube 1. By rotating the rotating locking cover 3, the rotating locking cover 3 is switched to the locked state. The connecting part 32 of the rotating locking cover 3 locks the connector 42 inserted into the first connecting hole 22, and the connecting pin 4 can be connected to the connecting assembly on the first lamp tube 1. Then, the connector 42 at the second end of the connecting pin 4 is inserted into the connecting assembly at the first end of the second lamp tube 1. By rotating the rotating locking cover 3, the connecting part 32 of the rotating locking cover 3 locks the connector 42 inserted into the first connecting hole 22. The two lamp tubes 1 are locked together by the connection of the two connecting assemblies and the connecting pin 4, realizing the combined connection of the two lamp tubes 1.

[0028] When it is necessary to connect a third lamp tube 1 to the second lamp tube 1, similarly, the above-mentioned connecting component is installed at the first end of the third lamp tube 1, and then the connectors 42 at both ends of the other connecting pin 4 are inserted into the connecting component at the second end of the second lamp tube 1 and the connecting component 10 at the first end of the third lamp tube 1, respectively. By locking the connecting component 10, the third lamp tube 1 and the second lamp tube 1 can be connected as one unit.

[0029] Similarly, when multiple lamp tubes 1 need to be connected, the above method is used to connect the multiple lamp tubes 1 end to end to connect the multiple lamp tubes 1 into a long strip-shaped lamp tube 1 lighting device. The length of the lamp tube 1 lighting device can be adjusted according to the number of lamp tubes 1.

[0030] Since the rotating cover 3 is located on the outside of the connecting seat 2, when the connector 42 of the connecting pin 4 is connected to the first connecting hole 22, the connector 42 needs to pass through the rotating cover 3 to be connected to the first connecting hole 22.

[0031] To prevent the rotating locking cover 3 from interfering with the connection head 42 connecting to the connection hole, see [reference needed]. Figures 6 to 8 In one embodiment provided in this application, the shapes of the first connecting hole 22 and the second connecting hole 321 are matched, and the shape of the connector head 42 on the connecting pin 4 matches the shape of the first connecting hole 22. The height of the connector head 42 on the connecting pin 4 matches the depth of the first connecting hole 22. When the connector head 42 is connected to the first connecting hole 22, the rotating lock cover 3 is rotated to the locked state, and the end face of the connector head 42 facing the connecting section 41 will abut against the connecting part 32 of the rotating lock cover 3. The connecting part 32 can restrict the connector head 42 from exiting the first connecting hole 22, effectively improving the stability of the connection between the two.

[0032] The shapes of the first connecting hole 22 and the second connecting hole 321 include, but are not limited to, square holes, triangular holes, elliptical holes, etc.

[0033] Furthermore, the connecting portion 32 is connected to the inner wall of the ring wall 31 along the diameter direction of the ring wall 31, and the connecting portion 32 is provided on the end face near one end of the ring wall 31. Corresponding to the center of the ring wall 31, a second connecting hole 321 is provided through the connecting portion 32, and the center of the second connecting hole 321 coincides with the center of the ring wall 31.

[0034] To prevent the connector 42 of the connecting pin 4 from loosening or shifting after being inserted into the first connecting hole 22, in one embodiment provided in this application, when the rotating lock cover 3 is in the locked state, the connecting part 32 abuts against the inner end face of the connector 42 to confine the connector 42 within the first connecting hole 22. Specifically, the distance from the inner end face of the connector 42 to the bottom of the first connecting hole 22 is equal to the height of the connector 42.

[0035] After the connector 42 is inserted into the first connecting hole 22, the connecting part 32 of the rotating lock cover 3 restricts the connector 42 within the first connecting hole 22 by rotating the rotating lock cover 3. If the height of the connector 42 is exactly equal to the depth of the first connecting hole 22, then when the connector 42 is slightly displaced, the connector 42 will abut against the connecting part 32, thus preventing the rotating lock cover 3 from rotating.

[0036] To avoid this problem, see [link / reference] Figure 8 and Figure 9 In one embodiment provided in this application, the inner end face of the connector 42 is a first inclined structure 421, and the inner end face of the connector 32 has a second inclined structure 322. When the rotating cover 3 is not yet locked, there is a gap between the second inclined structure 322 and the first inclined structure 421, thereby facilitating continued rotation of the rotating cover 3.

[0037] As the rotating cover 3 rotates gradually, the gap between the second inclined structure 322 and the first inclined structure 421 gradually decreases. When the rotating cover 3 is locked, the second inclined structure 322 abuts against the first inclined structure 421, and the second inclined structure 322 interacts with the first inclined structure to apply an inward force to the connector 42 along the axis of the connecting pin 4.

[0038] In the above embodiment, since both the first inclined surface structure 421 and the second inclined surface structure 322 are inclined surfaces, the force between the second inclined surface structure 322 and the first inclined surface structure 421 will cause the rotary lock cover 3 to rotate in the opposite direction, which will cause the rotary lock cover 3 to unlock automatically.

[0039] When the rotary cover 3 is switched to the locked state, in order to limit the rotary cover 3 to the locked state, see [link to relevant documentation]. Figure 3 , Figures 6 to 8 In one embodiment provided in this application, a locking component 5 is provided on the connecting base 2 or the rotating lock cover 3. The locking component 5 has an unlocked state and a locked state. By operating the locking component 5, the locking component 5 can be driven to switch between the unlocked state and the locked state.

[0040] Specifically, when the locking assembly 5 is in the unlocked state, the connecting seat 2 and the rotating lock cover 3 are disconnected and limited. By operating the rotating lock cover 3, the rotating lock cover 3 can rotate relative to the connecting seat 2. When the locking assembly 5 is in the locked state, the connecting seat 2 and the rotating lock cover 3 are mutually locked and limited.

[0041] In one specific embodiment, the locking assembly 5 includes a button 51 and an elastic element 52. The rotating lock cover 3 has a mounting hole 34, the button 51 is disposed in the mounting hole 34, and the elastic element 52 is disposed between the button 51 and the rotating lock cover 3. A limiting protrusion 23 is provided on the second end face of the connecting seat 2. Under the action of the elastic element 52, one end of the button 51 can interact with the limiting protrusion 23 on the connecting seat 2 to form a limiting effect.

[0042] The mounting hole 34 is provided through the ring wall 31 of the rotary lock cover 3. One end of the button 51 is exposed on the outer wall surface of the ring wall 31, and the other end of the button 51 extends through the ring wall 31 to the inner side of the ring wall 31. The operating direction of the button 51 is in the same direction as the diameter direction of the rotary lock cover 3. When the rotary lock cover 3 is connected to the connecting seat 2, the limiting protrusion 23 is also located on the inner side of the ring wall 31. When the rotary lock cover 3 is switched to the locked state, one end of the button 51 cooperates with the limiting protrusion 23 to limit the rotation of the rotary lock cover 3.

[0043] When it is necessary to unlock the rotary lock cover 3, press button 51. One end of button 51 is misaligned with the limiting protrusion 23. At this time, the rotary lock cover 3 can rotate relative to the connecting seat 2. After rotating a certain angle, the rotary lock cover 3 can switch to the unlocked state.

[0044] The lamp tubes are mainly used for mechanical connections between different lamp tubes 1. After multiple lamp tubes 1 are connected to each other, they also need to be able to achieve interconnection of circuits. See also Figures 3 to 6 In one embodiment provided in this application, at least two electrical connection interfaces 24 are further provided on the second end face, and a through hole 26 is provided on the connector 2. The electrical connection interface 24 extends from one side of the connector 2 to the other side of the connector 2. The types of the multiple electrical connection interfaces 24 can be the same or different. For example, when two electrical connection interfaces 24 are provided on the second end face, the types of the first electrical connection interface 24 and the second electrical connection interface 24 are different. The first electrical connection interface 24 on one lamp tube can be mated and plugged into the second electrical connection interface 24 on another lamp tube.

[0045] In addition, when the lamp tube is installed on the lamp tube 1, the first electrical connection interface 24 and the second electrical connection interface 24 of the lamp tube can be connected to the positive and negative terminals of the light source 12, respectively. When the lamp tube has another electrical connection interface 24, the electrical connection interface 24 can also be connected to the control circuit of the light source 12.

[0046] In the technical solution provided in this application, by setting multiple electrical connection interfaces 24 on the electrical connection interface 24, it is possible to connect the power supply circuits or control circuits between different lamp tubes 1 after multiple lamp tubes 1 are interconnected.

[0047] Furthermore, a protrusion 25 is provided on the outer side of the electrical connection interface 24, and the inner wall surface of the protrusion 25 abuts against a portion of the electrical connection interface 24. The protrusion 25 can provide a certain degree of protection for the electrical connection interface 24. When the electrical connection interface 24 is subjected to external force, the protrusion 25 can provide effective support on one side of the electrical connection interface 24, thereby preventing the electrical connection interface 24 from breaking under force.

[0048] See Figures 6 to 8 In one embodiment provided in this application, the connecting portion 32 forms a clearance space 35 corresponding to the electrical connection interface 24 and the protrusion 25. When the rotating cover 3 is connected to the connecting seat 2, the connecting portion 32 is located in the clearance space 35. During the rotation of the rotating cover 3, the connecting portion 32 is always located in the clearance space 35. When the rotating cover 3 is switched to the locked state or the unlocked state, the side wall surface of the connecting portion 32 will abut against the connecting portion 32 on the rotating cover 3. The connecting portion 32 can restrict the rotating cover 3 from continuing to rotate, and can prevent the rotating cover 3 from rotating arbitrarily and exceeding the rotation range.

[0049] See Figure 3To improve the protective effect of the lamp tube, the lamp tube also includes a cover plate 6. The cover plate 6 is rotatably mounted on the rotating locking cover 3. The cover plate 6 has through holes at the positions corresponding to the electrical connection port and the first connection hole 22. The outer end of the rotating locking cover 3 has a mounting groove, and the cover plate 6 can be fitted into the mounting groove. When the rotating locking cover 3 rotates relative to the connecting seat 2, the cover plate 6 will rotate relative to the rotating locking cover 3 under the limiting action of the electrical connection port.

[0050] See Figures 1 to 3 In one embodiment of this application, a lamp tube lighting fixture is also provided, comprising: a lamp tube 1 and the aforementioned lamp tube connecting devices, with two lamp tube connecting devices respectively disposed at both ends of the lamp tube 1. The lamp tube 1 includes a light source 12 and a protective shell 11. The lamp tube connecting devices can form a structural connection with the protective shell 11 and a circuit connection with the light source 12. Multiple lamp tubes can be connected end-to-end through the lamp tube connecting devices to form a lamp tube lighting fixture with a relatively long length.

[0051] For details on the specific structure of the lamp tube connection device, please refer to the description above; it will not be repeated here.

[0052] When multiple light tubes are connected and assembled, in addition to assembling them into linear lighting systems, there is also a need to assemble them into other shapes, such as assembling three light tubes into a triangular structure, assembling four light tubes into a square structure, assembling six light tubes into a hexagonal structure, etc.

[0053] To meet the above requirements, see Figures 12 to 14 In one embodiment of this application, a lamp tube lighting system is also provided, which includes a lamp tube 1, the aforementioned lamp tube connection device, and assembly components 7.

[0054] Two lamp tube connecting devices are respectively located at both ends of the lamp tube 1 to form a lamp tube lighting fixture. The surface of the assembly component 7 is provided with multiple mounting structures 71. The connecting pins 4 in the lamp tubes include at least two different structures; one type of connecting pin 4 has the same structure at both ends of the connector 42, while the other type has different structures at both ends of the connector 42. Some of the connector 4 connector 4 connector 42 can be connected to the mounting structures 71. Multiple lamp tubes 1 can be connected by multiple connecting components 10 and multiple different connecting pins, thereby assembling multiple lamp tube lighting fixtures into a lamp tube lighting fixture system with a freely designable shape.

[0055] See also Figures 1 to 3 In one embodiment provided in this application, the connecting pin 4 includes at least two structures, one of which has the same structure for the connectors 42 at both ends, such as the structure of the connectors 42 described above. This type of connecting pin 4 can be used to connect two lamp tubes into a straight line structure.

[0056] Another type of connecting pin 4 includes a first connecting head 43 and a second connecting head 44. The structure of the first connecting head 43 is the same as that of the connecting head 42 described above. The first connecting head 43 can be connected to the first connecting hole 22 of the lamp tube, while the second connecting head 44 can be connected to the mounting structure 71 on the assembly component 7. Multiple different lamp tubes can be connected to one assembly component 7 simultaneously. The two ends of a lamp tube can be connected to two assembly components 7 respectively through two such connecting pins 4. In the technical solution provided in this application, by combining and connecting multiple lamp tubes using two different connecting pins 4, it is possible to combine multiple lamp tubes to form lighting systems with different structural shapes.

[0057] See Figure 13 and Figure 14 In one specific embodiment, the assembly component 7 has a circular structure, and the mounting structure 71 has threaded connecting holes, with multiple connecting holes evenly arranged on the outer circumferential surface of the assembly component 7. The second connecting head 44 on the connecting pin 4 is a threaded connecting post that can be fitted into the connecting hole. A notch 45 is provided on the connecting section 41 near the second connecting head 44, allowing the connecting pin 4 to be easily tightened onto the assembly component 7.

[0058] In another specific embodiment, the assembly component 7 can also be a polyhedral structure, the mounting structure 71 is a connecting protrusion, and the second connector 44 on the connecting pin 4 is a mounting part with a socket, and the connecting protrusion can be connected with the mounting part.

[0059] In summary, the technical solution provided in this application allows the rotating cover to switch between a locked and unlocked state by rotation, thereby enabling the connection and separation of the connecting pin and the connecting seat. This lamp tube connection device has a simple structure and the rotation operation is simple and convenient. Because the connecting pin, once connected to the connecting seat, is limited by the rotating cover, it is not easily separated from the connecting seat, ensuring a stable and reliable connection.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
