Description

Technical Field

[0001] This utility model belongs to the technical field of stage lighting equipment, specifically relating to a splicing pin assembly for stage lights and a multi-combination stage light group. Background Technology

[0002] Stage lighting, also known as "stage illumination" or simply "lighting," is one of the core means of stage art design. Through the use of professional stage lighting equipment and technology, it provides indispensable light and shadow effects to the stage presentation, accompanying the development of the plot, shaping atmosphere, guiding the viewer's eye, and enhancing the performance. With the rapid development of technology, modern stages have placed unprecedented demands on the diversity and richness of lighting effects, driving continuous innovation in stage lighting technology.

[0003] The current development trend of stage lighting fixtures is significantly towards lightweighting, intelligentization, and functional integration. To create a more grand, complex, and varied perfect stage visual effect, it is often necessary to flexibly combine multiple light fixtures. Existing technology, such as the utility model patent previously filed by the applicant with publication number CN 222669832 U, entitled "Multi-directional Rapid Assembly Mechanism and Stage Light for Stage Lights," provides a solution. This solution mainly includes an assembly component, which has a first slot located on a first stage light body, a second slot located on a second stage light body, and a splicing plug that can simultaneously slide and insert with the first and second slots. Within the same assembly component, at least one slot has a movable locking member at its entrance, which engages or disengages with the splicing plug through reciprocating motion. This assembly mechanism design does indeed enable relatively rapid assembly and disassembly of multiple stage lights, simplifying the operation process. However, this technical solution has the following shortcomings: First, when the movable locking component is unlocked, it is completely detached from the first and second slots, making it extremely easy to lose during frequent disassembly and assembly, causing inconvenience and additional costs for equipment maintenance and on-site operation; Second, the mechanism relies on the horizontal pull-out splicing plug for unlocking. To achieve this function, additional splicing plugs and corresponding limit plates must be pre-set on the spliced ​​lamp bodies, resulting in a fragmented overall structure with numerous parts. This not only increases manufacturing costs and complexity but also hinders the modular design, production, and subsequent maintenance and assembly of the splicing components, affecting the overall reliability and convenience of the splicing system.

[0004] Therefore, there is an urgent need to provide a new type of stage lighting splicing pin assembly and a multi-combination stage lighting group based on it, in order to overcome the above-mentioned shortcomings of the existing technology and meet the urgent needs of the stage lighting field for safe, reliable, convenient, efficient and highly modular splicing technology. Summary of the Invention

[0005] In response to the problems in related technologies, this utility model proposes a splicing pin assembly for stage lights and a multi-combination stage light group to solve the technical problems of easy loss and difficulty in modular production during the disassembly and assembly of existing plug-in assemblies.

[0006] The technical solution of this utility model is implemented as follows: a stage light splicing pin assembly includes a first splicing component and a second splicing component, and a plug-in assembly for splicing the two together; wherein, the first splicing component is provided with a first slot, and the second splicing component is provided with a second slot; the plug-in assembly includes a pin slide, which simultaneously slides and engages with the first slot and the second slot; the front of the pin slide faces the first splicing component, and its back faces the second splicing component;

[0007] The first splicing component is provided with a linear limiting groove, which extends along the sliding direction of the first slot; the pin slide is provided with a limiting key that cooperates with the limiting groove to constrain the pin slide and prevent it from detaching from the first splicing component.

[0008] A connecting rod is also hinged to the pin slide, one end of which has a locking part for engaging with the lock hole on the first splicing component; the other end of the connecting rod is provided with a release rod for applying force; it also includes a first elastic member, which provides a pre-tightening force toward the lock hole to the locking part; the connecting rod reciprocates around its hinge point to achieve engagement or disengagement of the locking part with the lock hole.

[0009] This invention utilizes the sliding engagement of the limiting key and the limiting groove to ensure that the pin slide is always constrained and does not detach from the first splicing component, completely solving the problem of lost parts. Simultaneously, the anti-retrieval part automatically engages with the locking hole under elastic force to achieve locking; after pressing the release lever to disengage, the slide can be pulled out to unlock, making operation convenient. The plug-in assembly and adjacent components integrate sliding, limiting, and locking functions, resulting in a compact structure that facilitates standardized production and assembly, significantly improving the efficiency and reliability of stage lighting assembly.

[0010] As a further improvement to the above solution, the limiting groove includes a first groove and a second groove; the limiting key is a limiting screw, which is screwed in from the back of the pin slide and exposed from the front of the pin slide.

[0011] When the limit key moves to the first slot along with the pin slide, the anti-reverse part engages with the lock hole, and the first splicing component and the second splicing component lock each other.

[0012] When the limiting key moves to the second slot along with the pin slide, the pin slide slides out of the second slot, and the first splicing component and the second splicing component disengage from each other.

[0013] By setting mechanical hard limits in the first and second slots, the locking or disengaging states of the first and second splicing components are marked respectively, ensuring that the locking / disengaging states correspond precisely to the slide positions and avoiding misoperation.

[0014] As a further improvement to the above solution, the two sides of the front and back of the pin slide block protrude outwards to form slide bars; the slide bars slide in conjunction with the slots of the corresponding splicing components. The sliding engagement of the slide bars with the slots enhances the stability of the insertion and distributes the force. Both sides of the front and back of the pin slide block are provided with bidirectional extending slide bars, so that a single pin slide block can simultaneously fit the first slot and the second slot, improving splicing efficiency and stability.

[0015] As a further improvement to the above solution, each splicing component has inwardly hooked frame portions on both sides, with the inward hooks of the frame portions forming slots for the corresponding splicing components; there is a sliding space between the sliders on the same side of the two panels, allowing the same-side frame portions of the two splicing components to slide simultaneously. The inward hooks of the frame portions on both sides form slots, and the reserved sliding space between them and the sliders allows the frame portions of the two splicing components to slide into the same slide block synchronously. This enables a single plug-in assembly to simultaneously lock two splicing components, simplifying the splicing steps and significantly improving assembly efficiency.

[0016] As a further improvement to the above solution, the upper part of the pin slide is provided with a lifting part for applying force; the lifting part has a wedge-shaped structure that is wider on the outside and narrower on the inside; when the pin slide is spliced ​​with the two splicing components, the lifting part of the pin slide remains exposed. The structure that is wider on the outside and narrower on the inside facilitates the application of force by fingers, and the fact that the lifting part remains exposed after splicing facilitates the subsequent disassembly and separation of the two splicing components, ensuring ease of operation.

[0017] As a further improvement to the above solution, the front of the pin slide is provided with a recessed mounting cavity, and the bottom of the mounting cavity is provided with a through hole, which extends to the back of the pin slide; the connecting rod and the first elastic member are both located in the mounting cavity, one end of the release rod is hinged to the connecting rod, and the other end is exposed through the through hole to form a pressing part;

[0018] It also includes a fixing block covering the mounting cavity. The upper part of the fixing block is constructed as a wedge-shaped lifting part, and the lower part of the fixing block is provided with a passage groove. The anti-retraction part is hook-shaped and engages or disengages with the locking hole through the passage groove. The core sliding insertion, anti-disengagement limit, and press-type locking mechanism are integrated into the pin slide and adjacent splicing components, which facilitates standardized production and assembly. It also simplifies the docking structure of the lamp body, eliminating the need for pre-installed scattered splicing plugs and limit plates on the lamp body, thus reducing manufacturing complexity.

[0019] As a further improvement to the above solution, the extension length of the first slot is greater than the extension length of the second slot; and the extension length of the limiting groove is also greater than the extension length of the second slot. By setting the first slot to be longer than the second slot, and the limiting groove to be longer than the second slot, the second splicing component disengages first during unlocking, while the first splicing component remains constrained by the limiting groove. This ensures both the freedom of assembly and disassembly of the plug-in components and that the pin slide remains connected to the first splicing component during use and storage, reducing maintenance costs.

[0020] As a further improvement to the above solution, the bottom of the pin slide is also provided with a first magnetic attractor, and the bottom of the first or second splicing component is provided with a second magnetic attractor. When the pin slide is spliced ​​with the two splicing components, the first magnetic attractor and the second magnetic attractor magnetically attract each other. By automatically attracting the first magnetic attractor and the second magnetic attractor when the splicing is completed, a non-mechanical auxiliary fixation is added, eliminating vibration of the insertion gap and improving the impact resistance of the splicing structure.

[0021] As a further improvement to the above solution, the end faces of the first splicing component and the second splicing component facing the pin slide are each provided with a glass ball screw, and the axial directions of the two glass ball screws are perpendicular to the front and back surfaces of the pin slide, respectively.

[0022] The glass ball screw includes a pin with a hollow inner cavity, one end of which is provided with a constriction, the constriction being in communication with the inner cavity; a second elastic member and a steel ball are provided in the inner cavity of the pin; wherein, the steel ball is constrained inside the constriction, and the second elastic member provides a preload force for the steel ball to press against the constriction;

[0023] Both sides of the pin slide are provided with locking holes, which engage with the steel balls of the corresponding ball screws. The bidirectional vertical ball screws are elastically engaged into the locking holes of the pin slide by the steel balls, providing tactile feedback of proper insertion and allowing for minor deformation to compensate for assembly errors, thus solving the problem of cumulative tolerances when splicing multi-lamp arrays.

[0024] A stage lighting assembly includes multiple light bodies and a splicing pin assembly as described above. The multiple light bodies are arranged in a matrix. Each light body has a first splicing component on one side and a second splicing component on the opposite side. Adjacent light bodies can be locked or disengaged by the first splicing component and the plug-in component of one light body cooperating with the second splicing component of the other light body. The use of a universal splicing pin assembly enables the splicing of multiple light bodies, significantly reducing the complexity and maintenance costs of multi-light body systems.

[0025] Beneficial effects:

[0026] (1) By setting a linear limiting groove on the first splicing component and setting a matching limiting key on the pin slide, the pin slide is always physically constrained during the sliding insertion process and cannot be completely separated from the first splicing component. This ensures both the freedom of assembly and disassembly of the insertion component and that the pin slide remains connected to the first splicing component during use and storage, thus reducing maintenance costs.

[0027] (2) A connecting rod is hinged to the pin slide, with a stop part at one end that engages with the locking hole of the first splicing component, and a release rod at the other end for applying force, supplemented by a first elastic component providing pre-tightening force. When locked, the elastic force automatically drives the stop part to engage with the locking hole, forming a firm lock, which is convenient to operate and reliable in locking; when unlocking, only pressure needs to be applied to the release rod to overcome the elastic force driving the stop part to disengage, at which point the pin slide can be smoothly pulled out to achieve separation. This not only simplifies the unlocking action and avoids the dependence on space and additional structures required by traditional horizontal pull-out unlocking, but also makes the operation intuitive and labor-saving, significantly improving the efficiency of splicing and disassembly and the user experience.

[0028] (3) The core sliding plug-in, anti-disengagement limit, and press-type locking mechanisms are integrated into the plug slide and adjacent splicing components. On the one hand, the plug-in component itself becomes a fully functional and compact independent module, which is convenient for standardized production and assembly; on the other hand, it greatly simplifies the docking structure of the lamp body, eliminating the need to pre-install scattered splicing plugs and limit plates on the lamp body, reducing manufacturing complexity, and making it more conducive to realizing the overall modular and lightweight design of the stage lighting splicing system.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0055] Example:

[0056] like Figures 1-7 As shown, this embodiment provides a stage lighting assembly 1, including multiple light bodies D1 and splicing pin components 2. The multiple light bodies D1 are arranged and spliced ​​in a matrix. Each light body D1 has a first splicing component 21 on one side and a second splicing component 22 on the opposite side. Two adjacent light bodies D1 cooperate with the second splicing component 22 of the other light body D1 through the first splicing component 21 and the plug component 23 of one light body D1, so as to lock or unlock the two adjacent light bodies D1. The use of universal splicing pin components 2 enables the splicing of multiple light bodies D1, significantly reducing the complexity and maintenance cost of the multi-light body D1 system.

[0057] The splicing pin assembly 2 includes a first splicing member 21 and a second splicing member 22, and a plug-in assembly 23 that splices the two together; wherein, the first splicing member 21 is provided with a first slot 211, and the second splicing member 22 is provided with a second slot 221; the plug-in assembly 23 includes a pin slide 231, which simultaneously slides and engages with the first slot 211 and the second slot 221; the front Z1 of the pin slide 231 faces the first splicing member 21, and its back F1 faces the second splicing member 22;

[0058] The first splicing component 21 is provided with a linear limiting groove 212, which extends along the sliding direction of the first slot 211; the pin slide 231 is provided with a limiting key 232 that cooperates with the limiting groove 212 to constrain the pin slide 231 so that it does not detach from the first splicing component 21; in this embodiment, the limiting groove 212 includes a first slot 212a and a second slot 212b; specifically, the first slot 212a is located at the lower end of the limiting groove 212, and the second slot 212b is located at the upper end of the limiting groove 212;

[0059] The limiting key 232 is a limiting screw, which is screwed in from the reverse side F1 of the pin slide 231 and exposed from the front side Z1 of the pin slide 231. When the limiting key 232 moves with the pin slide 231 to the first slot 212a, the anti-retraction part 234 engages with the locking hole 213, and the first splicing member 21 and the second splicing member 22 are locked together. When the limiting key moves with the pin slide 231 to the second slot 212b, the limiting screw abuts against the end of the second slot 212b to form a hard limit, and the pin slide 231 slides out of the second slot 221, and the first splicing member 21 and the second splicing member 22 disengage. By setting the first slot 212a and the second slot 212b as mechanical hard limits, the locked or disengaged states of the first splicing member 21 and the second splicing member 22 are respectively marked, ensuring that the locked / disengaged state corresponds precisely to the position of the slide and avoiding misoperation.

[0060] In this embodiment, the extension length of the first slot 211 is greater than the extension length of the second slot 221; and the extension length of the limiting groove 212 is also greater than the extension length of the second slot 221. The first slot 211 is longer than the second slot 221, and the limiting groove 212 is also longer than the second slot 221. This ensures that when unlocking, the second splicing component 22 disengages first, while the limiting screw remains within the limiting groove 212, and the first splicing component 21 remains constrained by the limiting groove 212. This guarantees both the freedom of assembly and disassembly of the plug assembly 23 and ensures that the pin slide 231 remains connected to the first splicing component 21 during use and storage, reducing maintenance costs.

[0061] A connecting rod 233 is also hinged to the pin slide 231. One end of the connecting rod 233 has a stop portion 234 for engaging with the locking hole 213 on the first splicing component 21. The other end of the connecting rod 233 is provided with a release lever 235 for applying force. The middle part of the connecting rod 233 is hinged to the pin slide 231 via a first rotating shaft 2317 to form a lever structure. It also includes a first elastic member 236, which provides a preload force toward the locking hole 213 to the stop portion 234. The first elastic member 236 is a compression spring, one end of which abuts against the recess of the mounting cavity 2312, and the other end abuts against the rod body of the connecting rod 233 near the stop portion 234. The connecting rod 233 swings back and forth around its hinge point to achieve engagement or disengagement of the stop portion 234 with the locking hole 213.

[0062] In this embodiment, the two sides of the front and back surfaces F1 of the pin slide 231 protrude outwards to form slide bars 237; the slide bars 237 slide and engage with the slots of the corresponding splicing components. The sliding engagement of the slide bars 237 with the slots enhances the stability of the insertion and distributes the force. Both sides of the front and back surfaces F1 of the pin slide 231 are provided with bidirectional extending slide bars 237, so that a single pin slide 231 can simultaneously fit the first slot 211 and the second slot 221, improving splicing efficiency and stability.

[0063] In this embodiment, each splicing component has an inwardly hooked frame portion 214 on both sides, and the inward hook of the frame portion 214 forms a slot for the corresponding splicing component; there is a sliding space between the same-side slide bars 237 on the two panels, so that the same-side frame portions 214 of the two splicing components can slide simultaneously. The inward hook of the frame portions 214 on both sides forms a slot, and the reserved sliding space between the frame portions 214 and the slide bars 237 allows the frame portions 214 of the two splicing components to slide into the same slide block simultaneously. This enables a single plug-in component 23 to lock two splicing components simultaneously, simplifying the splicing steps and significantly improving assembly efficiency.

[0064] In this embodiment, the upper part of the pin slide 231 is provided with a lifting part 2311 for applying force; the lifting part 2311 has a wedge-shaped structure that is wider on the outside and narrower on the inside; when the pin slide 231 is spliced ​​with two splicing components, the lifting part 2311 of the pin slide 231 remains exposed. The structure that is wider on the outside and narrower on the inside facilitates the application of force by fingers, and the fact that the lifting part 2311 remains exposed after splicing facilitates the subsequent disassembly and separation of the two splicing components, ensuring ease of operation.

[0065] In this embodiment, the front Z1 of the pin slide 231 is provided with a recessed mounting cavity 2312, and the bottom of the mounting cavity 2312 is provided with a through hole 2313, which extends to the back F1 of the pin slide 231; the connecting rod 233 and the first elastic member 236 are both provided in the mounting cavity 2312; one end of the release rod 235 is hinged to the connecting rod 233 through the second rotating shaft 2318, and the other end is exposed through the through hole 2313 to form a pressing part;

[0066] It also includes a fixing block 2314 covering the mounting cavity 2312. The upper part of the fixing block 2314 is constructed as a wedge-shaped structure of the lifting part 2311, and the lower part of the fixing block 2314 is provided with a passage groove 2315. The anti-retraction part 234 is hook-shaped and engages or disengages with the locking hole 213 through the passage groove 2315. The core sliding insertion, anti-disengagement limit, and press-type locking mechanism are integrated into the pin slide 231 and adjacent splicing components, which facilitates standardized production and assembly. It also simplifies the docking structure of the lamp body D1, eliminating the need for pre-installed scattered splicing plugs and limit plates on the lamp body D1, thus reducing manufacturing complexity. The fixing block 2314 is detachably fixed to the opening of the mounting cavity 2312 by screws.

[0067] In this embodiment, the bottom of the pin slide 231 is further provided with a first magnetic attractor 2381, and the bottom of the first splicing component 21 is provided with a second magnetic attractor 2382. When the pin slide 231 is spliced ​​with the two splicing components, the first magnetic attractor 2381 and the second magnetic attractor 2382 magnetically attract each other. By automatically attracting the first magnetic attractor 2381 and the second magnetic attractor 2382 when the splicing is completed, a non-mechanical auxiliary fixation is added, eliminating vibration of the insertion gap and improving the impact resistance of the splicing structure.

[0068] In this embodiment, the first splicing component 21 and the second splicing component 22 are each provided with a glass ball screw 239 on the end face facing the pin slide 231, and the axial direction of the two glass ball screws 239 is perpendicular to the front and back surfaces F1 of the pin slide 231, respectively.

[0069] The glass ball screw 239 includes a pin 2391 with a hollow inner cavity. One end of the pin 2391 is provided with a constriction, which is connected to the inner cavity. The inner cavity of the pin 2391 is provided with a second elastic member 2392 and a steel ball 2393. The steel ball 2393 is constrained inside the constriction, and the second elastic member 2392 provides a preload force for the steel ball 2393 to press against the constriction. The second elastic member 2392 is a compression spring. The front and back sides F1 of the pin slide 231 are provided with locking holes 2316, which are engaged with the steel ball 2393 of the corresponding glass ball screw 239. The bidirectional vertical glass ball screw 239 is elastically engaged in the locking hole 2316 of the pin slide 231 by the steel ball 2393. When the pin slide 231 slides along the slot to the preset position, the steel ball 2393 is squeezed and compressed into the inner cavity of the pin 2391 until it is engaged in the locking hole 2316 and then pops out to form a lock. This provides tactile feedback of the insertion and allows micro-deformation to compensate for assembly errors, thus solving the problem of cumulative tolerance when splicing multiple lamp bodies D1 array.

[0070] In specific applications, the above-described solution of this utility model provides the following:

[0071] (1) Locking process:

[0072] First, align the two lamp bodies D1 to be spliced, ensuring that the mating surfaces of the first splicing component 21 of the first lamp body and the second splicing component 22 of the second lamp body are in contact. Next, holding the lifting part 2311 of the pin slide 231, insert the pin slide 231, which is restrained on the first splicing component 21, into the aligned first slot 211 and second slot 221, and push the slide towards the locking position along the slot direction. During the sliding process, the sliding strips 237 on both sides of the pin slide 231 slide and engage with the slots of the first splicing component 21 and the second splicing component 22, respectively, providing guidance and support. When the limit key 232 reaches the first slot 212a of the limit groove 212, the pin slide 231 stops moving. At this time, under the pre-tightening force of the first elastic member 236 inside the pin slide 231, the connecting rod 233 swings around its central hinge point, driving the anti-retraction part 234 at its front end to automatically pop out and engage with the locking hole 213 on the first splicing member 21, forming a rigid lock. Simultaneously, the first magnetic member 2381 and the second magnetic member 2382 at the bottom of the pin slide 231 attract each other, providing auxiliary fixation; the glass ball screws 239 and steel balls 2393 on both sides also engage with the locking holes 2316 on the front and back sides F1 of the pin slide 231 under the action of the spring, providing positioning feedback and preventing loosening. Thus, the first splicing member 21 and the second splicing member 22 are firmly locked together by the plug-in assembly 23, and the two lamp bodies D1 are spliced.

[0073] (2) Tripping process:

[0074] First, an inward pressing force is applied to the release lever 235 exposed on the pin slide 231. This pressure drives the connecting rod 233 to swing in the opposite direction around its hinge point, overcoming the preload of the first elastic member 236, and causing the front anti-retraction part 234 to disengage from the locking hole 213 of the first splicing member 21. Next, the pin slide 231 is pulled outward by the lifting part 2311. Since the length of the limiting groove 212 is greater than the length of the second slot 221, and the limiting key 232 is restricted to sliding within the limiting groove 212, the pin slide 231 first causes its reverse side F1 to disengage from the second slot 221 of the second splicing member 22, separating the second splicing member 22 and its associated lamp body D1 from the assembly. Then, the slide is pulled further until the limiting key 232 reaches the end of the second slot 212b of the limiting groove 212, forming a hard limit. At this point, the slide stops moving. During this process, the front Z1 of the pin slide 231 remains connected to the first splicing component 21 through the engagement of the limiting key 232 and the limiting groove 212, preventing complete disengagement and thus avoiding loss of parts. Simultaneously, the steel ball 2393 of the ball screw 239 is forced out of the retaining hole 2316 and retracts into the inner cavity of the pin 2391. At this point, the first splicing component 21 and the second splicing component 22 are disengaged, the two lamp bodies D1 are separated, and the pin slide 231 remains reliably constrained to the first splicing component 21.

[0075] This embodiment ensures that the pin slide 231 is always constrained and does not detach from the first splicing component 21 through the sliding engagement of the limiting key 232 and the limiting groove 212, thus completely solving the problem of lost parts. At the same time, the anti-retrieval part 234 automatically engages with the locking hole 213 under the action of elastic force to achieve locking. After pressing the release lever 235 to disengage, the slide can be pulled out to unlock, making operation convenient.
