Description
Technical Field
[0001] This utility model relates to the field of stage lighting auxiliary equipment technology, specifically to a quick assembly device for stage lights that prevents loosening. Background Technology
[0002] With the rapid development of the stage performance industry, higher requirements have been placed on the combination flexibility and installation efficiency of stage lighting. The use of multiple sets of stage lights spliced together is becoming increasingly common, such as forming light arrays, light and shadow curtains, or lighting systems with specific shapes.
[0003] Existing stage lighting splicing structures mainly adopt snap-fit, bolt, or magnetic designs. However, these traditional splicing methods have significant drawbacks: 1) Snap-fit connections rely on elastic deformation to achieve engagement, and are prone to fatigue wear under long-term vibration or external force, leading to gaps and loosening at the splicing points, or even snap-fit breakage due to stress concentration; 2) Although bolt connections have high stability, they require tools to tighten each bolt individually, and repeated alignment and calibration are necessary during disassembly and assembly, resulting in low efficiency and the possibility of the lamp falling off due to stripped threads; 3) Although magnetic connections are convenient to operate, the attraction force is limited by the magnet specifications and lacks a rigid positioning structure, making them prone to misalignment under high-frequency vibration or tilted installation. In addition, if metal debris is attracted to the magnetic surface, it will affect the connection accuracy.
[0004] The aforementioned structures generally suffer from the problem of balancing connection reliability and ease of assembly and disassembly. This not only leads to time-consuming and labor-intensive stage setup, but may also cause malfunctions such as deviations in light projection angles and poor circuit contact due to splicing failures. In severe cases, it may even pose a safety hazard of lamps falling, making it difficult to meet the needs of modern stage equipment for efficient and safe use. Utility Model Content

[0009] Furthermore, the rotating operating assembly includes a connecting shaft, a connecting block, a limiting chuck, and a pressure spring. The connecting block and the limiting chuck are spaced and fixed on the connecting shaft. One end of the connecting shaft passes through the front cover plate and is connected and fixed to the knob handle. The pressure spring is sleeved on the connecting shaft and is located between the front cover plate and the knob handle. One end of the positioning and locking assembly extends into the interior of the splicing housing and is respectively connected to the upper and lower ends of the connecting block.
[0010] Furthermore, the positioning and locking assembly includes a first indexing pin and a second indexing pin, which are symmetrically arranged on the upper and lower sides of the connecting shaft. Both the first and second indexing pins are composed of a positioning pin rod, a base, and a connecting rod. The ends of the positioning pin rods of the first and second indexing pins pass through the top and bottom of the splicing machine housing, respectively, and are exposed on the surface to form positioning protrusions. The ends of the connecting rods of the first and second indexing pins are inserted into the upper and lower ends of the connecting block and form a sliding fit with them.
[0011] Furthermore, the top and bottom of the splicing housing are respectively provided with an installation groove, and the anti-loosening component includes two sets of elastic elements, one set of elastic elements is installed in the installation groove at the top of the splicing housing, and the other set of elastic elements is installed in the installation groove at the bottom of the splicing housing.
[0012] Furthermore, the inner side of the front cover plate is provided with a first locking post, a second locking post, a first connecting post, and a second connecting post, and the side of the limiting chuck away from the front cover plate is provided with a third connecting post and a fourth connecting post, and tension springs are respectively connected between the first connecting post and the third connecting post, and between the second connecting post and the fourth connecting post.

[0017] The beneficial effects of this utility model are as follows:
[0018] (1) This utility model utilizes the T-shaped guide rail structure of the splicing body and the guide groove of the stage light to slide together. At the same time, the positioning protrusion formed by the first and second indexing pins exposed on the surface of the splicing body in the positioning locking component locks together with the corresponding bayonet of the stage light, thereby forming a firm mechanical lock. This effectively restricts the relative displacement between the splicing body and the stage light, so that the splicing process of the stage light quick splicing device and the stage light does not require complicated tools. Only a simple push-in and sliding operation is needed to realize the free splicing of multiple stage lights horizontally or vertically, meet the diverse needs of different stage scenes and lighting layouts, and greatly shorten the installation time.
[0019] (2) The stage light quick splicing device of this utility model is also equipped with the application of anti-loosening components. By utilizing the continuous action of the elastic force of its spring and the resistance of the friction force of the contact surface, a dynamic anti-loosening barrier is formed next to the positioning and locking components. This can fill and offset the micro gap at the connection between the positioning and locking components and the stage light, and also prevent the small displacement of the splicing body relative to the stage light, thereby suppressing loosening, ensuring the long-term stability of the splicing, and ensuring the safety of the performance process.
[0020] (3) The quick splicing device for stage lights of this utility model, through the cooperation of the knob handle and the rotating operation component, exposes the first indexing pin and the second indexing pin in the positioning locking component to the positioning protrusion formed on the surface of the splicing body, and performs retraction or extension operations, thereby locking the splicing body to the stage light, or pushing it out to detach it.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] As attached Figure 1-6As shown in the figure, this utility model embodiment provides a stage light quick splicing device with anti-loosening features, including a splicing housing 1, a front cover plate 2, a rear cover plate 3, a rotating operation component 4, a positioning and locking component 5, an anti-loosening component 6, and a knob handle 7. The front cover plate 2 and the rear cover plate 3 are respectively installed on the front and rear sides of the splicing housing 1 to form the splicing body. The rotating operation component 4 is installed inside the splicing body, with one end passing through the front cover plate 2 and connected and fixed to the knob handle 7. The positioning and locking component 5 and the anti-loosening component 6 are installed at intervals on the upper and lower sides of the splicing housing 1, and one end of the positioning and locking component 5 extends into the interior of the splicing housing 1 and is connected to the rotating operation component 4 for transmission. Through the cooperation of the splicing body, the rotating operation component 4, the positioning and locking component 5, and the knob handle 7, adjacent stage lights 8 can be spliced vertically or horizontally. At the same time, the anti-loosening component 6 provides continuous pressure and friction to prevent the positioning and locking component 5 from loosening due to vibration or external force, ensuring the long-term stability of the installation and splicing.
[0030] The top and bottom left and right sides of the splicing housing 1 are recessed to form a T-shaped guide rail structure 11. The tops of the positioning locking component 5 and the anti-loosening component 6 protrude from the upper surface of the T-shaped guide rail structure 11. The positioning locking component 5, the anti-loosening component 6 and the T-shaped guide rail structure 11 work together to splice two adjacent stage lights 8 together vertically or horizontally.
[0031] The rotating operation component 4 includes a connecting shaft 41, a connecting block 42, a limiting chuck 43, and a pressure spring 44. The connecting block 42 and the limiting chuck 43 are spaced and fixed on the connecting shaft 41. One end of the connecting shaft 41 passes through the front cover plate 2 and is connected and fixed to the knob handle 7. The pressure spring 44 is sleeved on the connecting shaft 41 and is located between the front cover plate 2 and the knob handle 7. One end of the positioning and locking component 5 extends into the interior of the splicing housing 1 and is connected to the upper and lower ends of the connecting block 42 respectively. The pressure spring 44 serves as a protective measure to prevent accidental activation of the knob handle 7 from causing a series of linkages that would unlock the positioning and locking component 5.
[0032] The positioning and locking assembly 5 includes a first indexing pin 51 and a second indexing pin 52. The first indexing pin 51 and the second indexing pin 52 are symmetrically arranged on the upper and lower sides of the connecting shaft 41. The first indexing pin 51 and the second indexing pin 52 are both connected by a positioning pin rod, a base and a connecting rod to form an L-shaped structure. The top and bottom of the splicing housing 1 are respectively provided with through holes. The positioning pin rod ends of the first indexing pin 51 and the second indexing pin 52 pass through the through holes at the top and bottom of the splicing housing 1 and are exposed on the surface to form positioning protrusions. The connecting rod ends of the first indexing pin 51 and the second indexing pin 52 are inserted into the upper and lower ends of the connecting block 42 and form a sliding fit with it.
[0033] Reference Figure 5 In a specific embodiment of this utility model, the side of the stage lamp 8 needs to be provided with a guide groove (which can be provided on the top, bottom, left, or right) that is compatible with the T-shaped guide rail structure 11 of the stage lamp quick splicing device of this utility model. The T-shaped guide rail structure 11 and the guide groove form a sliding fit, so that one end of the stage lamp quick splicing device can be connected and fixed to the stage lamp 8, and the other end can be connected and fixed to another stage lamp 8 to achieve splicing. In addition, a slot is provided in the guide groove of the stage lamp 8 that is compatible with the positioning protrusion of the positioning locking component 5 of the stage lamp quick splicing device, so that the positioning protrusion of the positioning locking component 5 can be locked in the slot to achieve further positioning and locking operation.
[0034] The top and bottom of the splicing housing 1 are respectively provided with a mounting groove 12. The anti-loosening component 6 includes two sets of elastic elements, one set of elastic elements is installed in the mounting groove 12 at the top of the splicing housing 1, and the other set of elastic elements is installed in the mounting groove 12 at the bottom of the splicing housing 1.
[0035] Specifically, both sets of elastic components include a spring piece 61 and a fastening screw 62. The spring piece 61 is fixed in the mounting groove 12 of the splicing housing 1 by the fastening screw 62. The spring piece 61 is set in an M shape, with its protrusion exposed on the upper surface of the mounting groove 12. By utilizing the continuous elastic force of the spring piece 61 and the resistance of the contact surface friction, a dynamic anti-loosening barrier is formed on the side of the positioning and locking assembly 5.
[0036] When the stage light quick splicing device of this utility model is used for splicing, the protruding part of its spring piece 61 will press against the inner surface of the guide groove of the stage light 8. Through its elasticity, it pre-compresses and generates a continuous thrust (pressure), which can fill and offset the micro gap at the connection between the positioning locking component 5 and the stage light 8. In addition, the friction generated between its protruding part and the inner surface of the guide groove of the stage light 8 forms a resistance, which can prevent the splicing body from the slight displacement of the stage light 8, thereby suppressing loosening and ensuring the long-term stability of the splicing.
[0037] Reference Figure 4The inner side of the front cover plate 2 is provided with a first locking post 21, a second locking post 22, a first connecting post 23, and a second connecting post 24 spaced apart. The side of the limiting chuck 43 away from the front cover plate 2 is provided with a third connecting post 431 and a fourth connecting post 432 spaced apart. Tension springs 45 are respectively connected between the first connecting post 23 and the third connecting post 431, and between the second connecting post 24 and the fourth connecting post 432. The tension springs 45 are used to reset the rotation operation component 4 and the positioning locking component 5. When the third connecting post 431 and the fourth connecting post 432 are offset, the tension springs 45 will be stretched. The elasticity of the tension springs 45 can be used to pull the third connecting post 431 and the fourth connecting post 432 back to their original positions, thereby resetting the limiting chuck 43, and then driving the connecting shaft 41, the connecting block 42, and the positioning locking component 5 to reset.
[0038] Reference Figure 4 The upper end of the connecting block 42 is provided with a first slot 421, and the lower end is provided with a second slot 422. The connecting rod end of the first indexing pin 51 is inserted into the top side of the first slot 421 and forms a sliding fit with it. The connecting rod end of the second indexing pin 52 is inserted into the bottom side of the second slot 422 and forms a sliding fit with it.
[0039] The limiting chuck 43 has a first slot 433 and a second slot 434. One end of the first locking post 21 and the second locking post 22 are respectively locked in the first slot 433 and the second slot 434. The end of the second locking post 22 protrudes a certain distance in front of the second slot 434. The first locking post 21 and the first slot 433 cooperate to limit the initial state of the limiting chuck 43, while the second locking post 22 and the second slot 434 cooperate to limit the rotation angle of the limiting chuck 43.
[0040] The front cover plate 2 and the rear cover plate 3 are provided with a plurality of screw fixing holes 25 spaced apart around their perimeters. Each of the plurality of screw fixing holes 25 is equipped with a mounting screw 26, which is used to fix the front cover plate 2 and the rear cover plate 3 to the front and rear sides of the splicing machine housing 1.
[0041] Among them, the T-shaped guide rail structure 11 of the splicing housing 1 has mounting holes 13 on both the front and rear sides.
[0042] Reference Figure 6 In other specific embodiments of this utility model, when only one stage light 8 needs to be suspended or fixed on the base plate 9, one end of the quick splicing device for stage lights of this utility model can be embedded in the connecting mounting base of the base plate 9, and the connecting mounting base can be connected and fixed to the upper screw fixing holes 25 of the front cover plate 2 and the rear cover plate 3, as well as the mounting holes 13 of the T-shaped guide rail structure 11, by using hexagonal screws 91, thereby fixing one end of the device, and splicing and fixing the other end to the stage light 8.
[0043] 1. In the specific implementation of this utility model, the working principle of using this stage light quick splicing device to splice multiple stage lights 8 is as follows:
[0044] In the initial state, the knob handle 7 of the stage light quick splicing device is kept vertical, and the ends of the positioning pins of the first indexing pin 51 and the second indexing pin 52 protrude from the upper surface of the splicing body to form positioning protrusions.
[0045] 1) First, press the knob handle 7 close to the front cover plate 2, so that the connecting shaft 41, the limiting chuck 43 and the connecting block 42 are pushed inward; at this time, the pressure spring 44 remains compressed, and the first slot 421 and the second slot 422 of the connecting block 42 move closer to the inside of the positioning pins of the first indexing pin 51 and the second indexing pin 52, respectively. The first slot 433 of the limiting chuck 43 disengages from the first pin 21, while the second pin 22 is still locked in the second slot 434. Thus, the limiting chuck 43 can maintain balanced rotation under the restriction of the cooperation between the second pin 22 and the second slot 434.
[0046] 2) Next, while holding the knob, rotate the knob handle 7 counterclockwise so that the connecting shaft 41, the limiting chuck 43 and the connecting block 42 are driven and rotate around the axis of the connecting shaft 41.
[0047] At this time, the orientation of the third connecting post 431 and the fourth connecting post 432 shifts counterclockwise with the limiting chuck 43, so that the two tension springs 45 are stretched, and the limiting chuck 43 maintains balanced rotation under the restriction of the cooperation between the second chuck 22 and its second chuck groove 434.
[0048] The orientation of the first slot 421 and the second slot 422 shifts counterclockwise with the connecting block 42, causing the connecting rod of the first indexing pin 51 to slide from its top side to its bottom side due to the restriction of the first slot 421, and the connecting rod of the second indexing pin 52 to slide from its bottom side to its top side due to the restriction of the second slot 422. As a result, the ends of the positioning pins of the first indexing pin 51 and the second indexing pin 52 are driven to retract under the restriction of the through hole.
[0049] 3) Finally, align the T-shaped guide rail structure 11 of the splicing body with the guide groove on the side of the stage light 8, and push it in along the horizontal direction of the guide groove. The initial positioning is achieved by the nesting and cooperation of the T-shaped guide rail structure 11 and the guide groove.
[0050] At the same time, release the knob handle 7, so that it, the connecting shaft 41, the limiting chuck 43, and the connecting block 42 are reset together. As a result, the positioning pin ends of the first indexing pin 51 and the second indexing pin 52 are reset and extend out of the upper surface of the splicing body to form a positioning protrusion, so as to engage with the corresponding slots pre-set on the stage lamp 8, thereby locking and fixing the splicing body and the stage lamp 8. At this time, the pressure spring 44 returns to its normal state.
[0051] 4) Repeat the above steps to use multiple stage light quick splicing devices to splice multiple stage lights 8 in either a vertical array, a horizontal array, or a two-dimensional array (combining vertical and horizontal).
[0052] 2. In the specific implementation of this utility model, the working principle of removing the stage light quick-assembly device from the stage light 8 is as follows:
[0053] 1) First, press the knob handle 7 close to the front cover plate 2, so that the connecting shaft 41, the limiting chuck 43 and the connecting block 42 are pushed inward; at this time, the pressure spring 44 remains compressed, and the first slot 421 and the second slot 422 of the connecting block 42 move closer to the inside of the positioning pins of the first indexing pin 51 and the second indexing pin 52, respectively. The first slot 433 of the limiting chuck 43 disengages from the first pin 21, while the second pin 22 is still locked in the second slot 434. Thus, the limiting chuck 43 can maintain balanced rotation under the restriction of the cooperation between the second pin 22 and the second slot 434.
[0054] 2) Next, while holding the knob, rotate the knob handle 7 counterclockwise so that the connecting shaft 41, the limiting chuck 43 and the connecting block 42 are driven and rotate around the axis of the connecting shaft 41.
[0055] At this time, the orientation of the third connecting post 431 and the fourth connecting post 432 shifts counterclockwise with the limiting chuck 43, so that the two tension springs 45 are stretched, and the limiting chuck 43 maintains balanced rotation under the restriction of the cooperation between the second chuck 22 and its second chuck groove 434.
[0056] The positions of the first slot 421 and the second slot 422 shift counterclockwise with the connecting block 42, so that the connecting rod of the first indexing pin 51 is restricted by the first slot 421 and slides from its top side to its bottom side, and the connecting rod of the second indexing pin 52 is restricted by the second slot 422 and slides from its bottom side to its top side. The ends of the positioning pins of the first indexing pin 51 and the second indexing pin 52 are driven to retract under the restriction of the through hole and disengage from the corresponding bayonet pre-set on the stage lamp 8.
[0057] 3) Finally, while maintaining this state, push the main body of the splicing out of the guide groove of the stage light 8 to remove it.
[0058] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
