It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0027] Figure 1 This is a schematic diagram of the connection device provided in the embodiments of this application. Figure 2 This is a schematic diagram of the connecting device provided in the embodiments of this application, omitting the cover plate, as shown. Figure 1 and Figure 2 As shown.

[0028] This application provides a connecting device 300, including: a main body 100, a locking assembly 30, a rotating housing 40, and a connector 50. The main body 100 includes a base 10 and a cover plate 20, which are stacked and connected to the base 10. The cover plate 20 is fixedly connected to the base 10 by fasteners, including but not limited to screws. A receiving cavity 101 is formed between the cover plate 20 and the base 10, and the cover plate 20 has a connecting hole 21 communicating with the receiving cavity 101. The locking assembly 30 is located within the receiving cavity 101 and is movably connected to the base 10. The rotating housing 40 is rotatably sleeved on the base 10 and is drivenly connected to the locking assembly 30. One end of the connector 50 has a connector head 51 that cooperates with the locking assembly 30.

[0029] Combination Figure 1 and Figure 2 See Figure 3 When the rotating housing 40 rotates to the unlocked position 301, the rotating housing 40 drives the locking assembly 30 to switch to the unlocked state, and the connector 51 can extend into the receiving cavity 101 through the connecting hole 21. When the rotating housing 40 rotates to the locked position 302, the locking assembly 30 switches to the locked state, and the locking assembly 30 connects with the connector 51 to lock the position of the connector 50. In this embodiment, the direction of rotation of the rotating housing 40 can be set according to different needs, such as... Figure 3 Taking the central position as an example, the direction in which the rotating outer shell 40 rotates toward the unlocking position 301 can be clockwise or counterclockwise. For example, in this embodiment, the direction in which the rotating outer shell 40 rotates toward the unlocking position 301 is counterclockwise. The direction in which the rotating outer shell 40 rotates toward the locking position 302 is the opposite of the unlocking position 301, that is, clockwise.

[0030] See also Figure 3 and Figure 4 The connecting device 300 provided in this application embodiment includes, but is not limited to, the splicing operation of the lamp tube 200, and can also be used for the splicing operation of other parts to be spliced. Taking the application of the connecting device 300 in the splicing operation of a long tubular lamp tube 200 as an example, the two ends of the lamp tube 200 can be respectively equipped with the connecting device 300, and the connecting device 300 is connected to the lamp tube 200 through the base 10.

[0031] When multiple lamp tubes 200 need to be spliced, first rotate the rotating housing 40 counterclockwise to the unlock position 301. The rotating housing 40 drives the locking component 30 to switch to the unlock state. When the rotating housing 40 rotates to the unlock position 301, the locking component 30 is in the unlock state. At this time, the connector 51 of the connector 50 can be inserted into the receiving cavity 101 from the connecting hole 21. Both ends of the connector 50 can be provided with connectors 51. After the connector 50 is aligned, rotate the housing 40 clockwise toward the locking position 302. At this time, the locking component 30 is switched to the locking state and connected to the connector 51 to lock the position of the connector 50.

[0032] At this time, combined Figure 3 and Figure 4 See Figure 5 A lamp tube 200a equipped with a connector 50 can be connected to a connector 300b on another lamp tube 200b via the connector 50 on one end of the connector 300a. The connection method can be referred to the above content, thereby completing the splicing between two adjacent lamp tubes 200. By repeating the above operation, multiple lamp tubes 200 can be spliced ​​together.

[0033] The technical solution provided in this application embodiment can easily connect two parts to be spliced ​​together through the connecting device 300, for example, it is convenient to splice two lamp tubes 200, and then different shapes can be spliced. It has the characteristics of simple structure, easy operation, convenient assembly and disassembly, and strong practicality.

[0034] Furthermore, depending on different splicing requirements, the other end of the connector 50 away from the connector head 51 can be configured with different structures, for example, see Figure 1 The connector 50 has a connector 51 at its other end, away from the connector head 51; that is, both ends of the connector 51 have connector heads 51. This arrangement allows multiple lamp tubes 200 to be connected end-to-end sequentially, such as... Figure 5 As shown, multiple light tubes 200 can be joined together to form a straight line. For another example, see... Figure 6 and Figure 7The connector 50 is provided with a hinge joint 52 at the other end away from the connector 51. The connector 50 is hinged to the connector 50 on the adjacent lamp tube 200, so that the two adjacent lamp tubes 200 can be connected at an angle, and thus can be spliced ​​into different shapes, such as triangles and other polygons.

[0035] For example, see Figure 8 The connector 50 has a threaded head 53 at the other end away from the connector head 51, and a universal ball 54 is connected to the threaded head 53. Through the connector 50 and the universal ball 54, multiple lamp tubes 200 can be connected to the universal ball 54, so that multiple lamp tubes 200 can extend in multiple directions, thereby splicing them into a more three-dimensional shape.

[0036] Further, see also Figures 1 to 3 When the connecting device 300 is applied to the lamp tube 200, in order to facilitate the electrical connection between lamp tubes 200, in some feasible embodiments of this application, the base 10 and the cover plate 20 are provided with through electrical connection holes 22. See Figure 7 and Figure 8 The electrical connection wire 55 can connect the two lamp tubes 200 through the electrical connection hole 22.

[0037] Combination Figure 2 See Figure 9 In one embodiment of this application, the locking assembly 30 may include at least one pair of opposing fixed locking plates 31. The fixed locking plates 31 are slidably connected to the base 10 and drivenly connected to the rotating housing 40. A locking spring 32 is provided on one end of the fixed locking plate 31 facing away from the other fixed locking plate 31, and the locking spring 32 is connected to the base 10. When the rotating housing 40 rotates to the unlocking position 301, it drives the two fixed locking plates 31 to move away from each other; when the rotating housing 40 rotates to the locking position 302, the locking spring 32 drives the two fixed locking plates 31 to move closer to each other.

[0038] When splicing the lamp tubes 200, rotating the outer shell 40 can drive the two fixing locking plates 31 to move away from each other. At this time, the locking plate spring 32 is compressed and deformed, allowing the connector head 51 of the connector 50 to be inserted between the two fixed locking plates 31. When the outer shell 40 rotates to the locking position 302, under the action of the locking plate spring 32, the fixing locking plates 31 move closer to each other, realizing the connection between the fixing locking plates 31 and the connector head 51, such as clamping or snapping, thereby realizing the installation of the connector 50 on the main body 100 and locking the position of the connector 50.

[0039] See also Figure 1 and Figure 9One configuration of the connector 51 is as follows: the connector 51 has a circumferentially circumferentially formed connecting groove 511; one end of the fixing locking piece 31 facing the other fixing locking piece 31 has an arc-shaped portion 311 adapted to the connecting groove 511; the base 10 has a positioning groove 11 corresponding to the position of the connecting hole 21; after the connector 51 extends into the receiving cavity 101 through the connecting hole 21, the connector 51 is positioned in the positioning groove 11, and the fixing locking piece 31 is connected to the connecting groove 511 of the connector 51 through the arc-shaped portion 311. The arc-shaped portion 311 of the fixing locking piece 31 can better contact the connecting groove 511 of the connector 51, and the two pairs of fixing locking pieces 31 can better wrap around the connector 51, improving the connection stability between the fixing locking piece 31 and the connector 50. At the same time, based on the multiple stabilizing effects of the positioning groove 11, the connecting groove 511, and the connecting hole 21, the relative position of the connector 50 can be more accurate, avoiding shaking after connection, thereby reducing the shaking of the lamp tube 200.

[0040] Based on the above-described arrangement of the connector 50, it is not necessary to drive the two fixing plates 31 away from each other by rotating the outer shell 40 when installing the connector 50. One arrangement is that the fixing plates 31 have a driving ramp on the side facing the connecting hole 21. When installing the connector 50, the connector head 51 of the connector 50 is first brought into contact with the driving ramp on the fixing plate 31, and then pressure is applied to the connector 50. Through the guiding action of the driving ramp, the connector head 51 compresses the paired fixing plates 31, causing the paired fixing plates 31 to move away from each other. The locking spring 32 is compressed, allowing the connector head 51 to extend into the positioning groove 11. When the connecting groove 511 on the connector head 51 corresponds to the fixing plate 31, under the action of the locking spring 32, the two fixing plates 31 move closer to each other, and the fixing plates 31 extend into the connecting groove 511, thereby enabling the connector 50 to be installed on the main body 100 and locking the position of the connector 50.

[0041] See also Figure 9 To ensure the stability of the movement of the fixing locking piece 31, in some feasible embodiments of this application, the base 10 is provided with at least a pair of opposing limiting walls 12, forming a limiting channel between the pairs of limiting walls 12; a pair of fixing locking pieces 31 are slidably provided between each limiting channel, and the fixing locking pieces 31 can slidably abut against the limiting walls 12. Through the limiting effect of the limiting walls 12, displacement of the fixing locking piece 31 in its width direction can be avoided, while also ensuring the accuracy of the movement direction of the fixing locking piece 31, thereby enabling the fixing locking piece 31 to accurately lock the connecting member 50.

[0042] Another way to ensure the stability of the movement of the fixing piece 31 is to provide a limiting groove 13 on the base 10 corresponding to the position of the fixing piece 31, see [link to relevant documentation]. Figure 10The fixing locking piece 31 is provided with a limiting protrusion 313 that cooperates with the limiting groove 13; each fixing locking piece 31 is slidably connected to a limiting groove 13 through the limiting protrusion 313. Through the limiting effect of the limiting groove 13 and the limiting protrusion 313, displacement of the fixing locking piece 31 in its width direction can be prevented, and the accuracy of the moving direction of the fixing locking piece 31 can be ensured, thereby enabling the fixing locking piece 31 to accurately lock the connecting member 50. The base 10 can be provided with a limiting wall 12 or a limiting groove 13 individually, or both limiting walls 12 and limiting grooves 13 can be provided.

[0043] See also Figure 9 and Figure 10 To further ensure the stability of the movement of the fixed locking plate 31, in some feasible embodiments of this application, the base 10 is provided with a mounting groove 14, and a mounting post 141 is provided in the mounting groove 14. The end of the locking plate spring 32 away from the fixed locking plate 31 abuts against the mounting groove 14 and is sleeved on the mounting post 141. The mounting groove 14 and the mounting post 141 can further fix the position of the locking plate spring 31 and further ensure the direction of force application of the locking plate spring 32, avoiding the locking plate spring 32 from moving in an unnecessary direction, which would lead to inaccurate spring force application and affect the movement direction and locking force of the fixed locking plate 31. Correspondingly, the fixed locking plate 31 may also be provided with a mounting protrusion, and one end of the locking plate spring 32 abuts against the fixed locking plate 31 and is sleeved on the mounting protrusion.

[0044] Combination Figure 2 See Figure 11 In this embodiment, one way the rotating housing 40 and the locking assembly 30 are connected is as follows: a driving part 41 is provided on the inner wall of the rotating housing 40 at a position corresponding to the fixed locking piece 31, and a guide groove 42 is provided on the driving part 41. A first inclined surface 421 is provided on the inner wall of the guide groove 42 away from the inner wall of the rotating housing 40, and a relief groove 422 recessed towards the inner wall of the rotating housing 40 is provided on the inner wall of the guide groove 42 near the inner wall of the rotating housing 40. A tightening mechanism 312 is provided on the fixed locking piece 31, and the tightening mechanism 312 is located within the guide groove 42. The tightening mechanism 312 includes, but is not limited to, a locking pin. When the rotating housing 40 rotates to the unlock position 301, the first inclined surface 421, in conjunction with the tightening mechanism 312, drives the two fixed locking plates 31 of the pair to move away from each other; when the rotating housing 40 rotates to the locking position 302, the guide groove 42 corresponds to the tightening mechanism 312 through the clearance groove 422, and the locking plate spring 32 drives the two fixed locking plates 31 of the pair to move closer to each other.

[0045] When it is necessary to keep the locking plates 31 apart, the rotating housing 40 can be rotated counterclockwise. The rotating housing 40 pushes the tightening mechanism 312 outward through the first inclined surface 421, thereby separating the two locking plates 31 so that the locking plates 31 can loosen the connector 50. The connector 50 can then be pulled out from the connecting hole 21, thus completing the separation of the two lamp tubes 200. When it is necessary to keep the locking plates 31 closer together, the rotating housing 40 can be rotated clockwise. The rotating housing 40 corresponds to the tightening mechanism 312 through the relief groove 422. Under the action of the locking plate spring 32, the two locking plates 31 can be brought closer together so that the locking plates 31 can connect with the connector 50 and lock the position of the connector 50.

[0046] To ensure a more stable locking of the fixing plate 31 onto the connector 50, in some feasible embodiments of this application, a second inclined surface 423 is provided on the inner wall of the guide groove 42 near the inner wall of the rotating housing 40. As the rotating housing 40 continues to rotate to the locked position 303 along the direction from the unlocked position 301 to the locked position 302, the guide groove 42 drives the paired fixing plates 31 closer together via the second inclined surface 423, locking the position of the paired fixing plates 31. After rotating the rotating housing 40 clockwise to the locked position 302, the connection between the fixing plate 31 and the connector 50 is complete, and the position of the connector 50 is locked. At this point, if the rotating housing 40 continues to rotate clockwise, the rotating housing 40 compresses the tightening mechanism 312 via the second inclined surface 423, thereby making the fixing plate 31 more tightly connected to the connector 50, ensuring a more stable and stable position for the connector 50, making the connector 50 suitable for high-strength connections.

[0047] See Figures 1 to 3 In some feasible embodiments of this application, the connecting device 300 further includes an anti-retraction mechanism 60, which is disposed on the rotating housing 40 and movably connected to the rotating housing 40; see also Figure 10 The base 10 is provided with an anti-reverse component 15 that works in conjunction with the anti-reverse mechanism 60. When the rotating housing 40 is rotated to the locked position 303, the anti-reverse mechanism 60 connects with the anti-reverse component 15 to lock the position of the rotating housing 40. When connecting the connector 50 to the main body 100, the rotating housing 40 is rotated clockwise, and the anti-reverse mechanism 60 rotates with the rotating housing 40, locking the connector 50 with the locking plate 31. When the rotating housing 40 is rotated clockwise to the locked position 303, the anti-reverse component 15 connects with the anti-reverse mechanism 60, preventing the rotating housing 40 from rotating further, including clockwise and counterclockwise rotation. This effectively prevents the rotating housing 40 from rotating back to the locked position 302 and the unlocked position 301, thus preventing the main body 100 from accidentally separating from the connector 50.

[0048] When the connector 50 is to be removed, disconnect the anti-reverse mechanism 60 from the anti-reverse component 15, and then rotate the rotating housing 40 counterclockwise so that the rotating housing 40 rotates to the unlock position 301. The rotating housing 40 drives the fixed locking piece 31 to separate. If the tightening mechanism 312 is pushed outward through the first inclined surface 421, the fixed locking piece 31 will be separated. At this time, the connector 50 can be pulled out of the connecting hole 21.

[0049] See Figure 10 and Figure 11 One possible implementation of the anti-reverse mechanism 60 is that it includes an anti-reverse button 61 and an anti-reverse spring 62. The anti-reverse spring 62 is located within the accommodating cavity 101, with one end connected to the rotating housing 40 and the other end connected to the anti-reverse button 61. The rotating housing 40 has a through hole 43, through which a portion of the anti-reverse button 61 can extend out of the accommodating cavity 101. The anti-reverse component 15 includes an anti-reverse pin, which is disposed on the side of the base 10 facing away from the accommodating cavity 101. The anti-reverse button 61 has an anti-reverse groove 611 corresponding to the position of the anti-reverse pin. When the rotating housing 40 rotates to the locked position 303, the anti-reverse button 61 connects to the anti-reverse pin through the anti-reverse groove 611 to lock the position of the rotating housing 40.

[0050] When connecting the connector 50 to the main body 100, rotate the rotating housing 40 clockwise. The anti-retraction mechanism 60 rotates with the rotating housing 40, and the fixing locking plate 31 locks the connector 50. When the rotating housing 40 is rotated clockwise to the locking position 303, the anti-retraction pin enters the anti-retraction groove 611, so that the rotating housing 40 can no longer rotate.

[0051] When the connector 50 is to be removed, press the anti-reverse button 61 toward the inside of the accommodating cavity 101. The anti-reverse button 61 moves together with the anti-reverse groove 611, causing the anti-reverse pin to exit the anti-reverse groove 611. Then rotate the rotating housing 40 counterclockwise, so that the rotating housing 40 rotates to the unlock position 301. The rotating housing 40 causes the fixed locking piece 31 to separate.

[0052] See also Figure 10One implementation of the anti-reverse groove 611 is that the anti-reverse groove 611 has a hook-shaped structure, with a guide slope 612 at the entrance of the hook-shaped structure. When the rotating housing 40 rotates to the locked position 303, the anti-reverse pin enters the anti-reverse groove 611 along the guide slope 612 and presses the anti-reverse button 61 to move into the receiving cavity 101. The anti-reverse button 61 compresses the anti-reverse spring 62, causing it to deform. When the rotating housing 40 rotates to the locked position 303, the anti-reverse pin passes over the anti-reverse spring 62, and the anti-reverse spring 62 pushes the anti-reverse button 61 to move out of the receiving cavity 101, and the anti-reverse pin enters the anti-reverse groove 611. By setting the guide slope 612, the anti-reverse pin can more easily enter the anti-reverse groove 611. The hook-shaped structure of the anti-reverse groove 611 can more effectively prevent the anti-reverse pin from coming out of the anti-reverse groove 611 without the action of external force after it enters the anti-reverse groove 611, thereby more effectively preventing the rotating housing 40 from continuing to rotate.

[0053] See Figure 2 In some feasible embodiments of this application, the rotating housing 40 is further provided with a capping spring 44; the base 10 is provided with a fixing block 16, and capping springs 44 are respectively provided on both sides of the fixing block 16, with one end of the capping spring 44 connected to the fixing block 16. When the rotating housing 40 is rotated counterclockwise to the unlocked position 301, the connector 50 can be pulled out from the connecting hole 21. When the external force is released, the rotating housing 40 can be rotated back to the locked position 302 under the action of the two capping springs 44 (e.g., Figure 3 (as shown in the figure) so that the two retaining plates 31 return to a position close to each other, that is, the two retaining plates 31 can be engaged in the connecting groove 511 on the connector 51, so as to make the next connection with the connector 50. When the anti-reverse mechanism 60 is released from the locked position 303, the rotating housing 40 can also be rotated back to the locked position 302 under the action of the two cap springs 44.
