[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention.

[0038] Embodiment 1

[0039] See also Figure 1 The utility model discloses a self-locking splicing piece 1, which includes a mounting shell; specifically, a locking cavity is provided in the mounting shell, see Figure 2 The locking cavity is provided with a plurality of splicing units and a connection position 111 for connecting with an external connection member 21, and the connection position 111 passes through the mounting shell. The splicing unit includes a self-locking component 14, a limit component 122 and a first elastic member 16. For details, refer to Figure 3 The self-locking component 14 is used to approach the connection position 111 so that the self-locking component 14 is in a locked state of locking the connection position 111, and the self-locking component 14 is used to move away from the connection position 111 so that the self-locking component 14 is in an unlocked state of unlocking the connection position 111. The two ends of the first elastic member 16 are respectively connected to the mounting shell and the self-locking component 14, and the first elastic member 16 is used to provide an elastic stress to drive the self-locking component 14 to approach the connection position 111; the limiting component 122 is arranged in the locking direction of the self-locking component 14, and is used to limit the self-locking component 14 from approaching the connection position 111 in the unlocked state.

[0040] It should be noted that the unlocking effect of the self-locking component 14 on the connection position 111 is manifested in that the external connection part 21 can be detached from or connected to the connection position 111; the locking effect of the self-locking component 14 on the connection position 111 is manifested in that after the external connection part 21 is connected to the connection position 111, the external connection part 21 cannot be detached from the connection position 111.

[0041] On the basis of this structure, when using the self-locking splicing piece 1 of the present invention, during the assembly process, the self-locking component 14 can be first installed on one side of the connecting position 111, and then the two ends of the first elastic member 16 can be connected to the mounting shell and the self-locking component 14 respectively; and then the limiting component 122 can be movably arranged on the mounting shell.

[0042] When in use, the self-locking component 14 can be first driven away from the connecting position 111 by external force to be used in an unlocked state, and then the limiting component 122 can be driven to pop out to the locking direction of the self-locking component 14 by external force or by utilizing the elastic force of the spring. After the external force on the self-locking component 14 is removed, the self-locking component 14 abuts against the limiting component 122 during the process of moving close to the connecting position 111. The limiting component 122 can overcome the elastic stress of the first elastic member 16 and limit the self-locking component 14 from approaching the connecting position 111, so that the self-locking component 14 remains in the unlocked state of unlocking the connecting position 111.

[0043] When splicing lamps, the self-locking splicing part 1 is connected to the external connecting part 21 of the lamp in the unlocked state. When the external connecting part 21 enters the locking cavity, the limiting component 122 moves away from the connecting position 111 under the action of external force or the top pressure of the external connecting part 21; after the external connecting part 21 is connected in place, the self-locking component 14 approaches the connecting position 111 under the action of the first elastic part 16, and connects with the external connecting part 21 in the connecting position 111, thereby realizing the locked state.

[0044] After the self-locking component 14 approaches the connection position 111, it can squeeze the external connection piece 21 in the connection position 111 or be limitedly connected with the external connection piece 21, thereby limiting the axial movement of the external connection piece 21, so that it cannot be separated from the self-locking splicing piece 1 under the locking action of the self-locking component 14. In addition, the limit component 122 can be installed in the locking cavity through the linkage piece on the mounting shell, and the user can manually operate the linkage piece to make the limit component 122 move closer to or away from the connection position 111; in addition, the limit component 122 can also be connected to the locking cavity through an elastic piece, and the limit component 122 moves toward the connection position 111 under the action of the elastic piece, and when the external connection piece 21 is inserted into the connection position 111, the limit component 122 is pressed by an external force and moves away from the connection position 111.

[0045] In this way, the limiting component 122 can maintain the unlocked state of the self-locking component 14 when the self-locking component 14 is switched to the unlocked state by the external force. The user does not need to continuously apply force to keep the self-locking component 14 away from the connection position 111, and can directly connect the external connection member 21 to the connection position 111, thereby improving the ease of operation. In addition, after the external connection member 21 on the lamp is connected to the connection position 111, the self-locking component 14 can automatically lock the connection position 111 under the elastic stress of the first elastic member 16, thereby limiting the external connection member 21 in the installation shell. The simple operation and automatic locking can prevent the problem of connection detachment caused by omission. In addition, the self-locking splicing piece 1 is provided with a plurality of splicing units, which can connect a plurality of lamps at the same time, so that a plurality of lamps can be assembled according to the usage scenario and needs, and the lighting area can be flexibly set.

[0046] Furthermore, the self-locking assembly 14 includes a self-locking lever 141, see Figure 3 The mounting shell is provided with a rotating shaft 15, and the self-locking lever 141 is rotatably connected to the mounting shell via the rotating shaft 15. The self-locking lever 141 is used to approach or move away from the connection position 111 during the rotation process, so as to lock the connection position 111 after approaching the connection position 111 or unlock the connection position 111 after moving away from the connection position 111.

[0047] On the basis of this structure, during assembly, the rotating shaft 15 can be fixedly arranged on the mounting shell, and then a rotation hole is arranged on the self-locking lever 141, and the self-locking lever 141 is rotatably connected to the rotating shaft 15 through the rotation hole. When locking, after the external connecting member 21 is connected to the connecting position 111, the self-locking lever 141 rotates close to the connecting position 111 under the action of the first elastic member 16, and is limitedly connected with the external connecting member 21 to be in a locked state. When unlocking, the self-locking lever 141 can be rotated away from the connecting position 111 under the action of an external force to be in an unlocked state, and the external connecting member 21 can be detached from the connecting position 111; then the limiting assembly 122 moves close to the connecting position 111, and after the external force applied to the self-locking lever 141 is removed, the self-locking lever 141 abuts against the limiting assembly 122, so that the self-locking lever 141 remains in an unlocked state.

[0048] In this way, unlocking or locking can be achieved by rotating the self-locking lever 141, with a simple structure and easy operation.

[0049] Further, see Figure 2 The mounting shell is provided with a guide groove 112, and the guide groove 112 includes a guide section and a locking section 113. The self-locking assembly 14 specifically includes a sliding column 145, a button 143 and a second elastic member 144, see Figure 7 , a sliding groove 146 is provided at the bottom of the self-locking lever 141, and a mounting groove is provided in the self-locking lever 141; specifically, the second elastic member 144 and the button 143 are arranged in the mounting groove, and the sliding column 145 is fixedly connected to the button 143. The sliding groove 146 has a first end close to the connection position 111 and a second end away from the connection position 111; the sliding column 145 passes through the sliding groove 146 and is slidably connected in the guide groove 112. In addition, the second elastic member 144 is used to provide an elastic stress to drive the button 143 away from the mounting groove, and the sliding column 145 is used to slide from the first end to the second end under the action of the elastic stress when sliding into the locking section 113, so as to drive the button 143 to pop out.

[0050] It should be noted that the locking section 113 is arranged at one end of the guide section away from the connection position 111; wherein the guide section extends along the circumferential direction of the mounting shell, and the locking section 113 extends along the radial direction of the mounting shell and in a direction away from the mounting shell.

[0051] Based on this structure, when unlocking, the sliding column 145 slides away from the connecting position 111 to the locking section 113 under the guidance of the guide section. When the sliding column 145 slides in the guide section, the sliding column 145 is limited by the groove wall of the guide groove 112 along the radial side of the mounting shell, so the sliding column 145 is in a state of compressing the second elastic member 144, and the sliding column 145 is located at the first end of the sliding groove 146, and the button 143 is located in the mounting groove of the self-locking lever 141.

[0052] See also Figure 4 When the sliding column 145 slides into the locking section 113, since the locking section 113 extends along the radial direction of the mounting shell and in the direction away from the mounting shell, the sliding column 145 will not be limited by the groove wall of the guide groove 112 along the radial side of the mounting shell. The sliding column 145 can slide along the first end of the sliding groove 146 to the second end under the action of the elastic stress of the second elastic member 144, and at the same time drive the button 143 to pop out; at this time, the sliding column 145 is pressed and held in the locking section 113 under the action of the second elastic member 144, and is not easy to slide.

[0053] In this way, by providing a locking section 113 at the end of the guide groove 112 in the unlocking direction, the sliding column 145 can be limited in the locking section 113 when the self-locking component 14 is in the unlocking state, preventing the sliding column 145 from sliding freely in the guide groove 112; and when it is necessary to lock the connecting position 111, force is applied to press the button 143 into the installation groove, so that the sliding column 145 can enter the guide section, and the sliding column 145 is guided by the guide section to approach the connecting position 111, which can make the locking of the self-locking lever 141 more accurate and the self-locking lever 141 more stable during the rotation process.

[0054] Furthermore, a limiting portion 142 is provided on a side of the self-locking lever 141 facing the connecting position 111 , and the limiting portion 142 is used to perform a limiting connection with the external connecting member 21 after the connecting position 111 is connected to the external connecting member 21 .

[0055] On the basis of this structure, the shape of the limiting portion 142 can be adapted to the outer circumference of the external connecting member 21; when the outer circumference of the external connecting member 21 is a circle, the limiting portion 142 can be set to a circular arc-shaped clamping ring; when the outer circumference of the external connecting member 21 is provided with a groove or a protrusion structure, the limiting portion 142 can be correspondingly set to a protrusion or groove structure, so that the self-locking lever 141 can be connected to the external connecting member 21 in a limited manner.

[0056] In this way, after the external connecting member 21 is inserted into the connecting position 111 along its own axial direction, the self-locking lever 141 can approach or move away from the connecting member 21 along the radial direction of the external connecting member 21 and limit the axial movement of the connecting member 21, thereby preventing the connecting member 21 from detaching from the connecting position 111 in the locked state.

[0057] Furthermore, the first elastic member 16 is a torsion spring, and the torsion spring is sleeved on the rotating shaft 15; specifically, the torsion spring has a fixed end and a rotating end, and a fixed slot 114 is provided on the mounting shell, wherein the fixed end is connected to the fixed slot 114, and the rotating end is connected to the self-locking lever 141. It should be noted that the self-locking lever 141 is used to rotate away from the connection position 111 under the action of an external force, and the rotating end is used to drive the self-locking lever 141 to rotate closer to the connection position 111 after the external force is removed.

[0058] Based on this structure, the rotating shaft 15 can be fixedly arranged on the self-locking lever 141, and a rotating hole can be arranged on the mounting shell; during assembly, the torsion spring is firstly sleeved on the rotating shaft 15, and the self-locking lever 141 is rotatably connected to the mounting shell through the rotating shaft 15. The fixed end of the torsion spring is clamped into the fixed groove 114, and the rotating end of the torsion spring is fixedly connected to the rod body of the self-locking lever 141.

[0059] During use, when the self-locking lever 141 moves away from the connecting position 111 under the action of external force, the self-locking lever 141 drives the rotating end of the torsion spring to rotate close to the fixed end and compress the torsion spring; when the external force is removed, the compressed elastic potential energy of the torsion spring drives the rotating end to rotate away from the fixed end and reset, and the rotating end drives the self-locking lever 141 close to the connecting position 111 while resetting.

[0060] In this way, the automatic locking function of the self-locking lever 141 can be realized by the elastic member, and different specifications of torsion springs can be selected to achieve different locking forces to ensure the reliable connection between the external connecting member 21 and the self-locking splicing member 1.

[0061] Further, see Figure 5 as well as Figure 6 The limiting assembly 122 is disposed above the connection position 111. Specifically, the limiting assembly 122 includes a limiting spring column 123 and a third elastic member 124, and the two ends of the third elastic member 124 are respectively in contact with the mounting shell and the limiting spring column 123; wherein the third elastic member 124 is used to provide an elastic stress that drives the limiting spring column 123 to move closer to the connection position 111. In addition, see Figure 5 A protrusion 125 is provided on the side of the limiting elastic column 123, and the protrusion 125 is used to drive the limiting elastic column 123 away from the connecting position 111 when pressed by an external force.

[0062] The protrusion 125 may be arranged in the connection direction of the external connection member 21; or the protrusion 125 may be connected via a linkage member, and the linkage member extends to the outside of the mounting shell.

[0063] Based on this structure, the third elastic member 124 can be a spring, and a mounting groove is provided on the side of the limiting spring column 123 facing the mounting shell. During assembly, the spring is installed in the mounting groove, and the two ends of the spring are respectively connected to the mounting shell and the bottom wall of the mounting groove, and the spring is in a compressed state.

[0064] The spring applies elastic stress to the limit spring to drive the limit spring 123 to approach the connection position 111; since the limit spring 123 limits the self-locking component 14 from rotating to approach the connection position 111 when approaching the connection position 111, the limit spring 123 maintains the locking state of the self-locking component 14. Before the splicing piece is connected to the external connection piece 21, it does not need to be unlocked, and the connection can be made in the unlocked state, which is convenient for installation.

[0065] Specifically, during use, when the protrusion 125 is arranged in the connection direction of the external connecting member 21, when the connecting member 21 is inserted and matched with the connecting position 111, the protrusion 125 is pressed by the top end of the connecting member 21 and moves away from the connecting position 111. At the same time, the protrusion 125 drives the limiting spring column 123 away from the connecting position 111 and compresses the third elastic member 124.

[0066] When the protrusion 125 is connected through a linkage, after the connector 21 is inserted and matched with the connection position 111, the user can apply force to the linkage to make the linkage press the protrusion 125 to move the protrusion 125 away from the connection position 111, and then the self-locking lever 141 can lock the connection position 111. The linkage can be a button or a bump, which can press the protrusion 125 under external pressure.

[0067] In this way, when the protrusion 125 is pressed by external force and drives the limiting spring column 123 away from the connecting position 111, the self-locking lever 141 is not abutted by the limiting spring column 123 in the locking direction, so the self-locking lever 141 can approach the connecting position 111 and fasten the external connecting member 21 under the action of the first elastic member 16.

[0068] Furthermore, the connection position 111 passes through one end of the mounting shell, and the end of the mounting shell away from the connection position 111 is provided with a receiving groove 121, see Figure 1 The receiving groove 121 is arranged corresponding to the connecting position 111. Figure 5The protrusion 125 is protrudingly disposed on the side wall of the receiving groove 121, and the protrusion 125 is slidably connected to the receiving groove 121. The protrusion 125 is used to slide away from the connection position 111 when the external connection member 21 enters the receiving groove 121 under the pressure of the external connection member 21.

[0069] On the basis of this structure, during assembly, a limiting groove can be set on the mounting shell, and the limiting groove is connected to the receiving groove 121; specifically, the limiting spring column 123 is set in the limiting groove, and the protrusion 125 extends into the receiving groove 121 through the limiting groove, and at the same time, the limiting spring column 123 is close to the connecting position 111 under the action of the third elastic member 124, and the side of the limiting spring column 123 is against the self-locking lever 141.

[0070] When splicing lamps, since the connection position 111 is in an unlocked state, the connector 21 of the lamp can be inserted into the locking cavity through the connection position 111, and in the process of the connector 21 extending from the connection position 111 to the receiving groove 121, the connector 21 will press the protrusion 125 located in the receiving groove 121 upward, so that the protrusion 125 drives the limiting spring column away from the connection position 111; then the self-locking lever 141 fastens the connector 21.

[0071] In this way, the limiting spring column 123 can be used to maintain the unlocked state of the self-locking component 14, and there is no need to unlock it when connecting the lamp, making the operation easier; at the same time, the connecting movement of the connecting piece 21 is used to release the limiting spring column 123 on the self-locking component 14, so that the self-locking component 14 can be automatically locked after the connecting piece 21 is connected to the connecting position 111.

[0072] Furthermore, a pressing plate 126 is provided below the protruding portion 125 , and the pressing plate 126 is connected to the mounting shell; wherein the pressing plate 126 is used to abut against the protruding portion 125 when the limiting spring column 123 is close to the connecting position 111 .

[0073] Based on this structure, after the protrusion 125 is installed in the limiting groove, the pressing plate 126 is connected to the notch of the limiting groove, so that the protrusion 125 cannot be separated from the limiting groove, and the limiting spring 123 can extend from the limiting groove.

[0074] In this way, when the limiting spring column 123 approaches the connection position 111 under the action of the third elastic member 124, the pressing plate 126 can abut against the protrusion 125, thereby limiting the protrusion 125 and the limiting spring column 123 to prevent the limiting spring column 123 from being separated from the limiting groove.

[0075] Furthermore, the mounting shell includes an upper shell 12 and a lower shell 11, and the upper shell 12 is connected to the upper part of the lower shell 11; it should be noted that a locking cavity is formed between the upper shell 12 and the lower shell 11. The splicing unit and the connection position 111 are both arranged on the lower shell 11, and the limit assembly 122 is arranged on the upper shell 12.

[0076] On the basis of this structure, during assembly, the upper shell 12 and the lower shell 11 can be connected by fasteners, and at the same time, the self-locking lever 141 of the splicing unit extends from the locking cavity to the outside so that the user can apply force to operate. When in use, the limiting component 122 pops out from the upper shell 12 to the top of the connection position 111, and the self-locking lever 141 approaches the connection position 111 in the horizontal direction, and abuts against the limiting component 122 before approaching the connection position 111, thereby maintaining the unlocked state. During splicing, the external connecting member 21 is inserted into the locking cavity from the connection position 111 of the lower shell 11 from bottom to top, and during the insertion process, the limiting component 122 is pressed against the upper shell 12, thereby releasing the limiting effect of the limiting component 122 on the self-locking lever 141, and the self-locking lever 141 can further approach the connection position 111 and fasten the external connecting member 21.

[0077] In this way, by configuring the mounting shell to be composed of an upper shell and an lower shell 11 , and configuring the splicing unit in the lower shell 11 , and configuring the limiting assembly 122 in the upper shell 12 , it is advantageous to utilize the connection direction of the connector 21 to release the limiting function of the limiting assembly 122 .

[0078] In addition, a clamping seat 13 is provided on the end surface of the upper shell 12 away from the lower shell 11. After the self-locking splicing piece 1 is connected to the lamp, it can be clamped on an external rack through the clamping seat 13 to adjust the irradiation direction and angle of the light source.

[0079] Embodiment 2

[0080] See also Figure 8 , different from the first embodiment, the present embodiment discloses a lighting device, which includes a panel light 2 and the self-locking splicing piece 1 in the first embodiment; wherein a plurality of panel lights 2 can be connected through the self-locking splicing piece 1 to form a larger area of ​​lighting. Specifically, the panel light 2 is provided with a connecting piece 21, and the connecting piece 21 is provided with a connecting portion 22; wherein the connecting piece 21 is used to connect with the connecting position 111 on the self-locking splicing piece 1, and the connecting portion 22 is used to perform a limiting connection with the self-locking component 14 on the self-locking splicing piece 1 after the connecting piece 21 is connected with the connecting position 111.

[0081] Based on this structure, the connecting piece 21 on the panel light 2 can be a connecting column or a connecting buckle, and the connecting part 22 on the connecting piece 21 can be a groove or a protrusion; the connecting position 111 on the splicing piece is a connecting hole, and the self-locking component 14 is provided with an arc groove or a recessed part corresponding to the connecting part 22.

[0082] During assembly, the connecting column or connecting buckle on the panel light 2 is inserted into the connecting hole on the self-locking splicing piece 1, and the connecting column or connecting buckle presses the limiting component 122 located above the connecting hole away from the connecting hole during the insertion process of the self-locking splicing piece 1. Therefore, after the connecting column or connecting buckle is inserted into place, the self-locking component 14 automatically approaches the connecting hole and fastens the connecting column or connecting buckle under the action of the first elastic member 16. The specific fastening process is that the arc groove or recessed portion on the self-locking component 14 is engaged with the groove or protrusion on the connecting piece 21, thereby realizing the limiting connection.

[0083] See also Fig. 9 After the connecting piece 21 is connected to the self-locking assembly 14, the axial movement of the connecting piece 21 is restricted, so the connecting piece 21 cannot be separated from the self-locking splicing piece 1. When unlocking, force can be applied to the self-locking assembly 14 to move it in a direction away from the connecting position 111, thereby releasing the limiting effect of the self-locking assembly 14 on the connecting piece 21, and the connecting piece 21 can be pulled out of the self-locking splicing piece 1.

[0084] In addition, when the connecting member 21 is pulled out of the self-locking splicing member 1, the top pressure exerted by the connecting member 21 on the limiting component 122 is removed, so that the limiting component 122 can move closer to the connecting position 111 again. In this way, after the external force on the self-locking component 14 is removed, the self-locking component 14 abuts against the limiting component 122 when approaching the connecting position 111, thereby maintaining the unlocked state of the self-locking component 14.

[0085] In summary, the lighting device in this embodiment connects multiple panel lights 2 through the self-locking splicing piece 1, thereby increasing the lighting area; and the splicing piece can be automatically locked after connecting the panel lights 2, ensuring that the panel lights 2 will not be separated from the splicing piece when it is not subjected to external forces, making the connection firm and reliable. In addition, the self-locking component 14 can remain unlocked under the action of the limit component 122, so there is no need to unlock before each connection of the panel lights 2, ensuring easy operation and quick installation by hand without using any tools.

[0086] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
