Description

Technical Field

[0001] This invention belongs to the field of lighting technology, and specifically relates to a lighting fixture docking locking device. Background Technology

[0002] In existing technologies, lighting fixtures, especially those requiring splicing and installation, typically employ a mechanical connection method using pins and latches. Users must perform the following operations: pull the pin, requiring additional force to overcome resistance, which is inconvenient; align and push out the latch, ensuring it is fully engaged, otherwise the splicing may be unstable; release the pin, requiring precise alignment of the pin and latch holes, otherwise the pin cannot be inserted smoothly. Furthermore, this process has the following drawbacks: it requires step-by-step operation, demanding a high level of user skill, leading to cumbersome operation; if the latch is not fully engaged or the pin is not aligned, connection failure may occur, resulting in low fault tolerance in existing devices; and when splicing multiple lighting fixtures, repetitive operations are time-consuming and labor-intensive, leading to low efficiency. Summary of the Invention

[0003] To address the aforementioned problems, the primary objective of this invention is to provide a lamp docking locking device, which solves the technical problems of cumbersome operation, locking connection failure, and low assembly efficiency in the current method of assembling two splicing parts using locking devices.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] This invention provides a lamp docking locking device, comprising:

[0006] The first splicing component is provided with a first positioning hole, and a first positioning structure is disposed in the first positioning hole;

[0007] The second assembly includes a movable component, which has a guide structure and a second positioning hole; wherein...

[0008] When the guide structure is disposed on the first splicing component, the first positioning structure passes through the first positioning hole and abuts against the guide structure until the second positioning hole is aligned with the first positioning hole. The first positioning structure is disposed on the second positioning hole, so that the first splicing component and the second splicing component are spliced ​​together.

[0009] Furthermore, the guide structure is disposed at the end of the movable member away from the second splicing member, and the second positioning hole is disposed at the end of the guide structure close to the second splicing member.

[0010] Furthermore, the guide structure includes a first guide portion; the first guide portion has an inclined surface; and a second positioning hole is formed by recessing inward from one side surface of the guide structure toward the first positioning hole.

[0011] Furthermore, as the guide structure moves within the first splice piece toward a side away from the second splice piece, the vertical distance between the first positioning hole and the inclined surface gradually decreases.

[0012] Furthermore, the first positioning structure is fastened to the first positioning hole; when the second positioning hole is aligned with the first positioning hole, the end of the first positioning structure away from the first positioning hole engages in the second positioning hole, so that the first splicing component and the second splicing component are spliced ​​together through the movable component and the first positioning structure.

[0013] Furthermore, the second splicing component is provided with a connected second guide groove and a clearance groove, and the second splicing component also includes a second positioning structure; wherein,

[0014] The movable part is slidably fitted into the second guide groove, and one end of the second positioning structure is connected to the movable part, while the other end is slidably disposed in the clearance groove.

[0015] Furthermore, the first splicing component is provided with a first guide groove, the first guide groove is connected to the first positioning hole, and the first positioning structure passes through the first positioning hole and extends into the first guide groove;

[0016] When the guide structure slides into the first guide groove, the first positioning structure abuts against the guide structure; when the second positioning hole is vertically aligned with the first positioning hole, the first positioning structure engages within the second positioning hole.

[0017] The first positioning structure includes a pin and a movable sleeve disposed on a portion of the outer peripheral surface of the pin. The movable sleeve has threads on its outer peripheral surface. The movable sleeve and the pin are connected by an elastic element. When the pin is squeezed by the guide structure, it is lifted upward.

[0018] Furthermore, one end of the second positioning structure is detachably connected to the movable part, and the other end is slidably fitted into the clearance groove and extends through the clearance groove.

[0019] Furthermore, the movable part has a mounting hole at the end away from the guide structure, and the second positioning structure is a bolt, which is threadedly connected to the mounting hole.

[0020] Furthermore, the lower end of the movable component is provided with a spring ball, which is pressed against the bottom of the second guide groove to prevent the movable component from loosening and slipping off naturally.

[0021] Compared with the prior art, the beneficial effects of this application are as follows: A lamp docking locking device includes: a first splicing member with a first positioning hole and a first positioning structure disposed in the first positioning hole; a second splicing member with a movable member disposed thereon, the movable member having a guide structure and a second positioning hole; when the guide structure is disposed on the first splicing member, the end of the first positioning structure away from the first positioning hole abuts against the guide structure until the second positioning hole is aligned with the first positioning hole, the first positioning structure is disposed in the second positioning hole, so that the first splicing member and the second splicing member are spliced ​​together. The movable component is movably positioned on the second splicing component. The end of the movable component furthest from the second splicing component is used to movably position on the first splicing component. As the movable component gradually moves towards the first splicing component, the end of the first positioning structure furthest from the first positioning hole abuts against the surface of the guide structure until the movable component moves to a point where the second positioning hole and the first positioning hole are vertically aligned. The end of the first positioning structure furthest from the first positioning hole then falls into the second positioning hole, thus locking the first positioning structure and the movable component together. Because the first positioning structure is positioned on the first splicing component and the movable component is positioned on the second connecting component, the first and second splicing components are spliced ​​together. The cooperation between the first positioning structure and the movable component achieves automatic alignment and locking of the first and second splicing components. The abutting design between the first positioning structure and the guide structure ensures that the second positioning hole accurately aligns with the first positioning hole, avoiding manual adjustment.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] To achieve the above objectives, the technical solution of the present invention is as follows:

[0038] See Figures 1-13 As shown, the present invention provides a lamp docking locking device, comprising: a first splicing member 10, having a first positioning hole 11, wherein a first positioning structure 12 is disposed within the first positioning hole 11; and a second splicing member 20, having a movable member 21 movably disposed thereon, wherein the movable member 21 has a guide structure 22 and a second positioning hole 23; wherein, when the guide structure 22 is disposed on the first splicing member 10, the end of the first positioning structure 12 away from the first positioning hole 11 abuts against the guide structure 22 until the second positioning hole 23 is aligned with the first positioning hole 11, and the first positioning structure 12 is disposed in the second positioning hole 23, thereby splicing the first splicing member 10 and the second splicing member 20.

[0039] The present invention provides a lamp docking locking device, wherein a first positioning hole 11 is provided in a first splicing member 10, a first positioning structure 12 is disposed in the first positioning hole 11, and is movably disposed on a second splicing member 20 via a movable member 21. The movable member 21 is provided with a guide structure 22 and a second positioning hole 23, wherein the guide structure 22 is used to be disposed on the first splicing member 10, and the end of the first positioning structure 12 away from the first positioning hole 11 is used to abut against the guide structure 22. When the first splicing component 10 and the second splicing component 20 need to be spliced, since the movable component 21 is movably disposed on the second splicing component 20, the end of the movable component 21 away from the second splicing component 20 is movably disposed on the first splicing component 10. As the movable component 21 gradually moves toward the first splicing component 10, the end of the first positioning structure 12 away from the first positioning hole 11 abuts against the surface of the guide structure 22 until the movable component 21 moves to the second positioning hole 23 and aligns vertically with the first positioning hole 11. The end of the first positioning structure 12 away from the first positioning hole 11 falls into the second positioning hole 23, thereby locking the connection between the first positioning structure 12 and the movable component 21. Since the first positioning structure 12 is disposed on the first splicing component 10 and the movable component 21 is disposed on the second splicing component 20, the splicing of the first splicing component 10 and the second splicing component 20 is realized. The automatic alignment and locking of the first splicing component 10 and the second splicing component 20 are achieved through the cooperation of the first positioning structure 12 and the movable component 21. The abutment design of the first positioning structure 12 and the guide structure 22 ensures that the second positioning hole 23 can be accurately aligned with the first positioning hole 11, avoiding manual adjustment. The mechanical self-guiding design significantly reduces the skill requirements of operators, making it particularly suitable for batch operations on production lines or on-site installation by end users.

[0040] Furthermore, the guide structure 22 is located at the end of the movable member 21 away from the second splicing member 20, and the second positioning hole 23 is located at the end of the guide structure 22 close to the first splicing member 10. The second positioning hole 23 is formed by recessing inward from the surface of the movable member 21 facing the first positioning hole 11, so that the second positioning hole 23 and the first positioning hole 11 can be vertically aligned subsequently. Since the guide structure 22 is located at the far end of the movable member 21, and the second positioning hole 23 is close to the second splicing member 20, a "guide first, lock later" process is formed, improving operational smoothness.

[0041] Furthermore, a groove 210 is formed by recessing the surface of the movable member 21 facing the first positioning hole 11 into the movable member 21, and the groove 210 penetrates the end of the movable member 21 away from the second splicing member 20 to form an opening 211. The guide structure 22 and the second positioning hole 23 are both disposed in the groove 210. Preferably, the movable member 21 is a rectangular block and the groove 210 is a U-shaped groove.

[0042] By fully integrating the guide structure 22 and the second positioning hole 23 into the groove 210, exposed components can be eliminated, the overall volume reduced, and installation in confined spaces facilitated. Furthermore, mechanical interference with other components during assembly can be avoided, and the internal mechanical structure concealed, enhancing the product's aesthetics. The through-hole opening 211 of the groove 210 serves as the initial contact point for the first positioning structure 12, ensuring precise guidance from the moment it enters the groove 210. The first positioning structure 12 naturally slides into the groove through the opening 211, reducing initial impact.

[0043] Furthermore, the guide structure 22 includes a first guide portion 221 and a second guide portion 222, with the first guide portion 221 connected to the second guide portion 222; the first guide portion 221 is provided with an inclined surface 223, and the side surface of the second guide portion 222 facing the first positioning hole 11 is connected to the inclined surface 223 to form an obtuse angle, with one end of the inclined surface 223 away from the second guide portion 222 extending to the opening 211 of the groove 210; the second positioning hole 23 is formed by recessing inward from the side surface of the second guide portion 222 facing the first positioning hole 11.

[0044] Furthermore, the obtuse angle ranges from 90° to 180°; preferably, the obtuse angle ranges from 90° to 120°, or from 120° to 150°, or from 150° to 180°.

[0045] Furthermore, as the guide structure 22 moves toward the first splice 10 within the second splice 20, the vertical distance between the first positioning hole 11 and the inclined surface 223 gradually decreases.

[0046] Furthermore, the first positioning structure 12 is a spring pin, and the first positioning structure 12 is fastened to the first positioning hole 11. Specifically, the first positioning structure 12 includes a pin 122 and a movable sleeve 120 disposed on a portion of the outer peripheral surface of the pin 122. The movable sleeve 120 has threads 121 on its outer periphery, and the movable sleeve 120 is connected to the pin 122 by an elastic element 123. When the second positioning hole 23 is aligned with the first positioning hole 11, the end of the first positioning structure 12 away from the first positioning hole 11 is engaged in the second positioning hole 23. Specifically, the threads 121 are fitted into the second positioning hole 23 so that the first splicing component 10 and the second splicing component 20 are spliced ​​together by the movable element 21 and the first positioning structure 12.

[0047] The inclined surface 223 of the first guide portion 221 extends to the opening 211, ensuring that the first positioning structure 12 is guided upon initial contact and smoothly transitions to the compressed state. The sidewall of the groove 210 restricts the lateral displacement of the first positioning structure 12, ensuring that the first positioning structure 12 always moves along the predetermined path of the inclined surface 223. The U-shaped groove structure of the groove 210 prevents the first positioning structure 12 from accidentally disengaging from the guide area during compression or locking. The inclination angle of the inclined surface 223 optimizes the pushing force to balance with the first positioning structure 12, avoiding laborious operation or the first positioning structure 12 failing to reset. The second positioning hole 23 is recessed into the surface of the second guide portion 222, ensuring that the first positioning structure 12 deeply engages with the second positioning hole 23 after locking, enhancing pull-out resistance and vibration resistance. By progressively compressing the first positioning structure 12, the instantaneous impact force is reduced, extending its service life. The first positioning structure 12, i.e., the pin, always moves along the predetermined path under the guidance of the inclined surface 223, eventually automatically aligning with the second positioning hole 23, eliminating manual adjustment errors and achieving precise alignment. The design of the inclined plane 223 structure allows the first splicing component 10 and the second splicing component 20 to be joined simply by pushing out the movable part 21, which automatically presses against the first positioning structure 12, causing the pin to move upward. When the second positioning structure 26 of the movable part 21 is pushed into place, the pin automatically presses down and inserts into the second positioning hole 23, thus fixing the first splicing component 10 and the second splicing component 20 together, saving installation time and steps. Preferably, both the first splicing component 10 and the second splicing component 20 are long strip lights.

[0048] Furthermore, the second splicing component 20 is provided with a connected second guide groove 24 and a clearance groove 25, and the second splicing component 20 also includes a second positioning structure 26; wherein, the movable component 21 is slidably engaged with the second guide groove 24, one end of the second positioning structure 26 is connected to the movable component 21, and the other end is slidably disposed in the clearance groove 25. The second guide groove 24 strictly restricts the sliding direction of the movable component 21, ensuring that it can only move along a preset straight path and avoids deflection or rotation; the clearance groove 25 provides a dedicated sliding space for the second positioning structure 26, such as a bolt, so that it is not obstructed by other structures when the movable component 21 moves; the length of the clearance groove 25 determines the maximum displacement of the movable component 21, ensuring that it moves sufficiently to complete the locking, and preventing excessive pushing and pulling from damaging the components; by observing the position of the exposed second positioning structure 26 in the clearance groove 25, the current state of the movable component 21 can be intuitively judged, ensuring that the movable component 21 and the second splicing component 20 always maintain a physical connection. Therefore, high-precision mechanical control is achieved in a limited space through the second guide groove 24 and the clearance groove 25, which is particularly suitable for industrial lighting scenarios that require frequent operation and high reliability. The second guide groove 24 and the moving part 21 adopt an H-shaped guide rail cooperation structure to further reduce the coefficient of friction.

[0049] Furthermore, the first splicing component 10 is provided with a first guide groove 13, which is connected to the first positioning hole 11. The end of the first positioning structure 12 away from the first positioning hole 11 extends into the second guide groove 24. When the guide structure 22 is slidably engaged with the second guide groove 24, the first positioning structure 12 abuts against the guide structure 22. When the second positioning hole 23 is vertically aligned with the first positioning hole 11, the first positioning structure 12 is engaged in the second positioning hole 23.

[0050] Furthermore, a spring ball 213 is provided at the lower end of the movable part 21. The spring ball 213 is pressed against the bottom of the second guide groove 24 to prevent the movable part 21 from loosening and slipping off naturally. Specifically, one end of the spring ball 213 is fixedly connected to the movable part 21, and the end of the spring ball 213 away from the movable part 21 is slidably engaged with the bottom of the second guide groove 24. The bottom of the second guide groove 24 is provided with a groove 241, which is recessed relative to the bottom of the second guide groove 24 towards the side away from the spring ball 24. When the movable part 21 moves along the second guide groove 24 to the point where the second positioning hole 23 is vertically aligned with the first positioning hole 11, the first positioning structure 12 engages in the second positioning hole 23, and the end of the spring ball 213 away from the movable part 21 is pressed and limited by the groove 241.

[0051] When the first splicing component 10 and the second splicing component 20 are spliced, a continuous guiding channel is formed by the connection of the first guide groove 13 and the second guide groove 24, allowing the first positioning structure 12, i.e., the pin, to naturally cross the boundary area between the first splicing component 10 and the second splicing component 20, eliminating the stepped jamming phenomenon commonly found in traditional solutions. The through design of the first guide groove 13 and the second guide groove 24 allows the first positioning structure 12, i.e., the pin, to adaptively adjust its position within a certain range, compensating for minor dimensional deviations during part processing or assembly. The first positioning structure 12, i.e., the pin, can be removed laterally from the first guide groove 13, i.e., from the first positioning hole 11 and the second positioning hole 23, enabling quick replacement.

[0052] Furthermore, one end of the second positioning structure 26 is detachably connected to the movable part 21, and the other end is slidably fitted into the clearance groove 25 and extends through the clearance groove 25.

[0053] Furthermore, the end of the movable part 21 away from the guide structure 22 is provided with a mounting hole 212, and the second positioning structure 26 is a bolt, the outer periphery of the bolt is threadedly connected to the inner periphery of the mounting hole 212.

[0054] It should be added that the first splicing component 10 is provided with a first mating plate 14 on the side facing the second splicing component 20, and the second splicing component 20 is provided with a second mating plate 27 on the side facing the first splicing component 10. After the first splicing component 10 and the second splicing component 20 are spliced ​​together, that is, the first positioning structure 12 is simultaneously disposed inside the first positioning hole 11 and the second positioning hole 23, so that when the first positioning structure 12 locks the end of the movable component 21 away from the second splicing component 20 to the first splicing component 10, the first mating plate 14 and the second mating plate 27 abut against each other, that is, the first mating plate 14 and the second mating plate 27 form a stacked structure. In addition, a first buffer layer 141 is provided between the end face of the first mating plate 14 and the first splicing component 10, and a second buffer layer 271 is provided between the end face of the second mating plate 27 and the second splicing component 20. Both the first buffer layer 141 and the second buffer layer 271 are rubber layers. The design of the first mating plate 14 and / or the second mating plate 27 can achieve a dustproof effect.

[0055] The assembly process of the lamp docking locking device provided by the present invention is as follows:

[0056] 1. Component pre-assembly preparation

[0057] 11. Assembly of the first splice component 10:

[0058] The first positioning structure 12, i.e., the pin, is pressed into the first positioning hole 11 to ensure that the pin can slide axially.

[0059] Check the connectivity between the first guide groove 13 and the first positioning hole 11 to ensure that the protruding end of the pin can smoothly enter the first guide groove 13.

[0060] 12. Assembly of the second splice 20:

[0061] Slide the movable part 21 along the second guide groove 24 and test the sliding resistance of the movable part 21 in the second guide groove 24.

[0062] The second positioning structure 26, i.e., the bolt, is screwed into the mounting hole 211, with the tail of the bolt extending into the clearance groove 25, and tightened to the preset torque.

[0063] 2. Docking process between the first splicing component 10 and the second splicing component 20

[0064] 21. Initial Alignment:

[0065] Bring the mating ends of the first splicing piece 10 and the second splicing piece 20 close together so that the first guide groove 13 and the second guide groove 24 are roughly aligned.

[0066] 22. Push the movable part 21 so that the inclined surface 223 of the guide structure 22 begins to contact the first positioning structure 12. The inclined surface 223 converts the lateral thrust into a vertical component force, compressing the pin.

[0067] The groove 210 guides the pin to slide along the inner wall of the groove 210 to avoid lateral displacement.

[0068] 3. Automatic locking:

[0069] When the movable part 21 moves to the end point, the second positioning hole 23 is completely aligned with the first positioning hole 11;

[0070] The first positioning structure 12, i.e., the spring pin, quickly springs downward into the second positioning hole 23 under the restoring force of the elastic element 123, achieving a locking engagement. At the same time, the spring ball 213 at the bottom of the movable element 21 also slides into the corresponding groove 241 at the bottom of the second guide groove 24, providing tactile and auditory feedback of positioning and preventing it from slipping off on its own.

[0071] The present invention provides a lamp docking locking device, which significantly reduces the skill requirements of operators through mechanical self-guiding design, and is particularly suitable for batch production line operations or on-site installation by end users.

[0072] The present invention provides a lamp docking locking device, wherein a first positioning hole 11 is provided in a first splicing member 10, a first positioning structure 12 is disposed in the first positioning hole 11, and is movably disposed on a second splicing member 20 via a movable member 21. The movable member 21 is provided with a guide structure 22 and a second positioning hole 23, wherein the guide structure 22 is used to be disposed on the first splicing member 10, and the end of the first positioning structure 12 away from the first positioning hole 11 is used to abut against the guide structure 22. When the first splicing component 10 and the second splicing component 20 need to be spliced, since the movable component 21 is movably disposed on the second splicing component 20, the end of the movable component 21 away from the second splicing component 20 is movably disposed on the first splicing component 10. As the movable component 21 gradually moves toward the first splicing component 10, the end of the first positioning structure 12 away from the first positioning hole 11 abuts against the surface of the guide structure 22 until the movable component 21 moves to the second positioning hole 23 and aligns vertically with the first positioning hole 11. The end of the first positioning structure 12 away from the first positioning hole 11 falls into the second positioning hole 23, thereby locking the connection between the first positioning structure 12 and the movable component 21. Since the first positioning structure 12 is disposed on the first connecting component 10 and the movable component 21 is disposed on the second splicing component 20, the splicing of the first splicing component 10 and the second splicing component 20 is realized. The first positioning structure 12 and the movable part 21 cooperate to achieve automatic alignment and locking of the first splicing part 10 and the second splicing part 20; the abutment design of the first positioning structure 12 and the guide structure 22 ensures that the second positioning hole 23 can be accurately aligned with the first positioning hole 11, avoiding manual adjustment.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
