Description

TECHNICAL FIELD

[0001] The utility model relates to stage lamp technical field especially, relates to a stage lamp convenient to effect module assembly noise reduction. BACKGROUND

[0002] Stage lighting equipment is an important part of modern stage performance, which has various functions, involving color, pattern, light beam and other effects. Among them, the effect module in the lamp head is the key to the stage light effect change, for example, the CMY color mixing system, which is one of the core technologies to realize the color change of stage lamp. The CMY module usually contains cyan (Cyan), magenta (Magenta) and yellow (Yellow) three color filters (CMY color plate), which realizes rich and colorful color mixing by cutting these color plates into the light path of the light source independently or in combination.

[0003] In the prior art, the slider and slide rod cooperation structure of the effect module in the stage lamp lamp head usually adopts the structure that the slider directly contacts and slides with the slide rod, or a sliding bushing or shaft sleeve is arranged between the slider and the slide rod to improve the sliding performance, reduce wear and noise. A common structure is that the slider body is made of metal material to ensure strength and precision, and an annular shaft sleeve made of soft material such as silica gel is arranged at the position where the slider contacts the slide rod as a sliding interface and noise reduction buffer.

[0004] However, the existing scheme of metal slider cooperating with silica gel shaft sleeve has some technical problems. First of all, the soft shaft sleeve needs to be installed on the hard metal slider usually by mechanical pressing and other ways. The pressing process has high tolerance requirements, and often needs additional fixing process after the shaft sleeve is pressed in, such as pressing point fixing of the shaft sleeve around the slider to prevent the shaft sleeve from falling out during use. These additional installation processes make the assembly process complex, inconvenient to operate, and low in automation, which affects the production efficiency. Secondly, although the pressing point fixing is performed, under the working conditions of high-speed movement, frequent vibration or sudden stop and start of the stage lamp, the connection between the shaft sleeve and the slider may not be firm enough when the slider slides quickly along the slide rod, which may cause loosening, falling or axial displacement, resulting in unstable operation of the effect module, affecting the light effect and color mixing effect, and even causing equipment failure.

[0005] In order to simplify the assembly and improve the connection reliability, there are also attempts to integrate the slider and the bushing and to use plastic forming manufacturing. For example, the entire slider together with the sliding sleeve inside it is made into an integral plastic part. This integrated structure can simplify the installation process in theory. However, if soft or noise-reducing plastic material is selected as the material of the entire slider in order to achieve the noise reduction effect, the problem of insufficient structural strength may be faced. Soft plastic materials generally have low mechanical strength and are prone to deformation when bearing the weight of the color plate, the tension of the belt and the inertial force, resulting in unstable movement trajectory of the slider on the slide rod, which is difficult to meet the strict requirements of the effect module on position accuracy and assembly size. Especially when the slider structure needs to be stable and not deformed to adapt to complex optical paths, this defect is particularly prominent. At the same time, if the integrated structure needs to use special noise-reducing materials with high price, and the entire slider is made of such materials, the overall manufacturing cost will be very high, which is not economical.

[0006] Taking the CMY color mixing system in the stage lamp head as an example, in a typical CMY module structure, the CMY color plate is usually installed on one or more sliders that can move along the guide rail or slide rod. The slider is driven by a driving mechanism (such as a motor and a belt) to reciprocate on the slide rod, thereby adjusting the depth of the color plate in the light path. This sliding structure is the key to realizing CMY color mixing. The cooperation mode of the slider and the slide rod directly affects the positioning accuracy, movement stability and running noise of the CM plate. Practical new type content

[0007] Therefore, the utility model provides a stage lamp convenient for effect module assembly and noise reduction, aims at overcoming the problems of complex installation process, easy falling or displacement of the bushing, insufficient strength of the integrated structure and high cost of the overall use of noise-reducing materials in the prior art.

[0008] The utility model discloses a stage lamp convenient for effect module assembly and noise reduction, including the head, support arm and bottom machine case, the support arm is pivoted on the bottom machine case, the head is pivoted in the support arm, be provided with the light source and the effect module in the light source light -emitting direction in the head, the effect module is equipped with slide and is used for reciprocating the effect piece of cutting into the light source light path, the effect module still includes:

[0009] Hard slider, connect in the effect piece and the movable loading on the slide, be equipped with the bushing mounting seat on the hard slider,

[0010] Soft bushing, the soft bushing is inserted in the bushing mounting seat and is sleeved with the outer surface of the slide,

[0011] The soft shaft sleeve is provided with an elastic reverse buckle, which can be compressed and deformed when the soft shaft sleeve is axially inserted into the shaft sleeve mounting seat, and can be elastically reset and buckled to the hard slider when one end of the soft shaft sleeve reaches a predetermined position.

[0012] In the above technical solution, the hard slider is a component connected with the effect sheet, used to carry the color plate and move on the slide rod. The slider is defined as "hard", which means that its material has high structural strength and dimensional stability, and can usually be made of metal or hard plastic. This hard characteristic ensures that the slider itself is not easily deformed under high-speed reciprocating motion and lamp vibration, thereby maintaining the connection accuracy with the color plate and the stable loading posture on the slide rod. In addition, the hard slider is provided with a structure for mounting the shaft sleeve, i.e. the shaft sleeve mounting seat. This mounting seat can be understood as one or a group of specially shaped holes, slots or cavities formed on the slider body, and its internal structure is designed for subsequent installation of the soft shaft sleeve. The soft shaft sleeve is a component that directly contacts and slides with the slide rod. The shaft sleeve is defined as "soft", which means that its material has a certain elasticity and shock absorption and noise reduction capacity, and is usually made of soft plastic or other materials. The soft shaft sleeve is designed to be inserted into the shaft sleeve mounting seat, and the central hole of the soft shaft sleeve is sleeved on the slide rod. When the slider moves along the slide rod, the soft shaft sleeve actually slides with the slide rod, and the existence of the soft material helps to reduce friction noise and vibration. In addition, the soft shaft sleeve is formed with an elastic reverse buckle. The elastic reverse buckle is one or a group of structure features (such as elastic claws or annular elastic lips) on the shaft sleeve body, which have elasticity, outward protrusion or can be deformed under force and reset. It can be understood that during assembly, the soft shaft sleeve is axially inserted (pressed) into the shaft sleeve mounting seat of the hard slider. Since there may be a narrowing or narrower channel inside the shaft sleeve mounting seat, when the elastic reverse buckle on the soft shaft sleeve contacts the narrowing or channel wall, it will be elastically deformed (contracted) inwardly under the radial extrusion force. The shaft sleeve continues to be pressed until the elastic reverse buckle passes through the predetermined position (such as a wider cavity or end edge) inside the shaft sleeve mounting seat. Once passing through this position, the elastic reverse buckle immediately returns to its original outward protruding state by virtue of its own elasticity, at which time the elastic reverse buckle is "docked" or "clamped" into a corresponding structure (such as a groove, an edge or a cavity wall) inside or at the end of the shaft sleeve mounting seat. The docking effect after elastic reset forms a reliable axial fixation, preventing the soft shaft sleeve from being pulled out of the hard slider in the direction opposite to the pressing direction (i.e. the pulling-out direction). In combination with the limiting step on the shaft sleeve, the shaft sleeve can be further ensured not to move significantly axially in the slider. During the operation of the stage lamp, the effect sheet is driven by a transmission belt or other mechanism, thereby driving the hard slider connected therewith to reciprocate on the slide rod. Since the soft shaft sleeve has been reliably fixed inside the hard slider and sleeved on the slide rod, the actual sliding contact occurs between the outer surface of the soft shaft sleeve and the outer surface of the slide rod. The shock absorption and buffering characteristics of the soft material effectively absorb the slight vibration and friction generated during sliding, thereby reducing the operating noise. At the same time, the hard slider maintains the rigidity of the overall structure, ensuring the positioning accuracy of the effect sheet in the light path.

[0013] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided on the soft bushing. The first limiting step and the second limiting step are respectively located at different positions in the axial direction of the soft bushing.

[0014] When the soft bushing is axially inserted into the bushing mounting seat and reaches the predetermined installation position, the first limiting step and the second limiting step abut against the bushing mounting seat or the hard slider from opposite directions.

[0015] It is understood that the elastic buckle primarily addresses the issue of the bushing disengaging in the reverse direction along the insertion direction. However, during the high-speed reciprocating motion of the slider along the slide rod, especially at start-stop or reversal moments, significant inertial or impact forces are generated. While the elastic buckle provides some fixation, without additional axial restraint, the bushing may still experience slight axial movement or vibration under these alternating loads, potentially leading to increased wear or loosening of the connection over time. Therefore, the first and second limiting steps added in the above solution provide bidirectional axial restraint for the bushing relative to the slider. Once the bushing is in place, these two steps "clamp" the corresponding structures (e.g., the end face of the through hole) on the bushing mounting base or slider in the middle, or prevent axial displacement of the bushing by abutting against both end faces. This bidirectional mechanical locking mechanism, combined with the radial elastic buckle of the elastic buckle, greatly enhances the stability of the bushing within the slider. Specifically, the effects of this bidirectional limiting technology are as follows: 1. Improved connection reliability: It effectively suppresses axial movement or impact caused by the bushing during high-speed movement, sudden stops, reversals, and external vibrations of the slider, ensuring that the bushing remains stably in the predetermined installation position. This significantly reduces the risk of bushing loosening, displacement, or even detachment, improving the long-term operational reliability of the effect module. 2. Enhanced positioning accuracy: The axial position of the bushing within the slider is precisely defined, helping to maintain the stable mounting posture of the slider on the slide bar, indirectly contributing to the precise entry / exit positioning of the effect piece. Although this is not the primary effect, it has a positive impact on the overall module performance. 3. Extended service life: Friction and impact caused by axial movement are significant factors leading to component wear. Bidirectional limiting reduces this unnecessary relative movement, thereby reducing wear between the bushing and the bushing mounting base / slider, as well as between the bushing and the slide bar, extending the overall service life of the component and module. In summary, the above technical solution, by setting bidirectional limiting steps on the soft bushing, provides a more stable and reliable axial positioning, significantly improving the stability and reliability of the connection between the bushing and the slider.

[0016] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided, wherein the first limiting step is formed on the snap-fit ​​surface of the elastic buckle and is respectively disposed at the opposite ends of the soft bushing with the second limiting step.

[0017] In the above scheme, the function of the first limiting step is integrated into the snap-fit ​​surface of the elastic buckle. This means that while providing radial snapping force, the elastic buckle's own axial bearing surface also acts as the first limiting step. This design reduces additional structural elements, making the bushing structure more compact and integrated. Furthermore, by placing one limiting element (the first limiting step) at one end of the bushing (integrated with the elastic buckle) and the other limiting element (the second limiting step) at the other end, it ensures that the slider or bushing mounting base is effectively confined between the two axial endpoints of the bushing. This explicit end-to-end confinement layout maximizes the constraint on the axial movement range of the bushing, providing a more reliable and sufficient bidirectional limiting effect, further enhancing connection stability. Moreover, the integration of specific structures (such as the elastic buckle and the first limiting step) and the explicit end layout facilitate the injection molding process of soft plastic bushings, reducing complexity or stress concentration and optimizing material usage. Therefore, the above technical solution provides a more specific and more integrated bidirectional limiting structure by clearly defining the position of the first limiting step and combining it with the elastic buckling function, and by clearly defining that the second limiting step is located at the opposite end.

[0018] According to this utility model, a stage light that facilitates the assembly of effect modules and reduces noise is provided, wherein the bushing mounting base has a through hole inside; the soft bushing is axially inserted into the through hole and cooperates with the through hole;

[0019] When the soft bushing is axially inserted into the through hole and reaches the predetermined installation position, the first limiting step and the second limiting step respectively abut against the opposite end faces of the through hole to jointly clamp the bushing mounting seat.

[0020] In the above scheme, a through hole is used as the mounting hole for the bushing, a design that allows the bushing to be easily inserted in a straight axial direction. The first and second limiting steps abut against the opposite end faces of the through hole, forming an axial clamping force on a specific area of ​​the bushing mounting base. This clamping force, combined with the radial locking force of the elastic undercut, constitutes a very robust mechanical connection. This not only prevents axial movement of the bushing in both directions but also further reduces potential gaps through axial pre-tightening or tight fit, thereby minimizing vibration and movement and significantly enhancing the rigidity and stability of the connection. Furthermore, machining a through hole in a rigid slider or its bushing mounting base is a relatively simple and precise machining process, while injection molding a soft bushing with limiting steps and elastic undercuts is a standard plastic molding technique. This fit design is beneficial for mass production and assembly. Therefore, the above technical solution, by specifying the bushing mounting base as a structure with a through hole and detailing how the limiting steps on the bushing engage with the two end faces of the through hole to form a clamping force, achieves a concrete and efficient bushing installation and bidirectional fixing structure.

[0021] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided, wherein there are several first limiting steps and several second limiting steps, and each of the first limiting steps and the second limiting steps is circumferentially surrounding the periphery of the soft bushing.

[0022] It is understandable that designing the limiting steps as several circumferentially distributed independent units, rather than a continuous monolithic ring, can bring the following technical benefits. First, it optimizes the injection molding of soft plastics. Continuous, thick ring structures are prone to shrinkage, stress concentration, or uneven cooling during injection molding, affecting the precision and performance of the component. Using several dispersed limiting steps reduces the volume and thickness of individual features, facilitating uniform material filling and cooling, reducing molding difficulty, and improving the dimensional accuracy and stability of the soft bushing. Secondly, the dispersed flexible limiting steps, when pressed in or abutting, may more easily achieve slight elastic deformation than a continuous rigid ring, thus absorbing fit tolerances to a certain extent and ensuring effective abutment and limiting even with certain manufacturing errors. Furthermore, although the limiting structure is discontinuous, these circumferentially distributed step assemblies can still effectively abut against the corresponding structure of the bushing mounting seat or slider (such as the end face of the hole or internal step), thereby achieving bidirectional axial limiting. In summary, the above technical solutions optimize the manufacturing process of soft bushings, potentially save materials, and may improve the fault tolerance of the fit by dispersing and circumferentializing the limiting structure while maintaining the bidirectional axial limiting function.

[0023] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided, wherein each of the first limiting steps and each of the second limiting steps are staggered in the circumferential distribution direction.

[0024] The above-described scheme arranges two sets of circumferentially distributed limiting steps in a staggered manner. The technical advantages are as follows: First, it optimizes the distribution of axial load. When the bushing clamps the bushing mounting base through the two steps, if the two sets of steps are radially aligned, the axial load will concentrate on the same radial section of the bushing mounting base, potentially leading to localized stress concentration. Staggering the two sets of steps disperses the axial load to different circumferential positions on the bushing mounting base or slider, thus distributing stress more evenly, reducing localized stress peaks, and improving the structural strength and durability of the bushing mounting base or slider in that area, preventing deformation or damage under long-term stress. Second, it facilitates assembly. In cases where there are deviations in fit tolerances or bushing insertion angles, the staggered arrangement of the steps may make it easier to align and press the bushing in, avoiding jamming due to interference between the steps and the mating surfaces during insertion. Third, it can further optimize the molding of soft plastics, as the staggered arrangement may provide better demolding convenience or runner design space in some complex mold designs. In summary, the above technical solution specifies that two sets of circumferentially distributed limiting steps are staggered, which further optimizes the mating structure between the bushing and the bushing mounting seat or slider, improves the uniformity of load distribution, and enhances the structural reliability of the mating area.

[0025] According to this utility model, a stage light with noise reduction that facilitates the assembly of effect modules is provided, wherein the soft bushing is made of soft plastic and the hard slider is made of metal or hard plastic.

[0026] It is understandable that the soft plastic bushing, as the contact interface between the slider and the slide bar, can effectively absorb and attenuate the vibration and impact generated when the slider moves on the slide bar due to its inherent elasticity and damping characteristics. When the slider slides rapidly or is subjected to vibration, the soft bushing undergoes slight elastic deformation, converting some of the mechanical energy into heat or other forms of energy dissipation, significantly reducing the noise generated by direct collision and friction between the hard components (slider / slide bar). This directly solves the problem of high operating noise when the slider slides at high speed in existing technologies. Secondly, maintaining the use of metal or hard plastic material for the slider ensures that the slider, as a key structural component in the effects module that carries the color plate and moves along the slide bar, has sufficient mechanical strength and rigidity. This avoids the problems of insufficient structural strength and easy deformation when using integral soft or one-piece molded plastic sliders in existing technologies. The high-strength and high-rigidity slider can stably carry the color plate and maintain its precise position, meeting the requirements of the effects module for assembly accuracy and dimensional stability, ensuring accurate light path, and not affecting the color mixing effect. Furthermore, compared to existing technologies that integrally mold the entire slider using expensive noise-reducing materials, this invention uses soft plastic (likely a low-cost, commonly used soft plastic) only for the bushing component, while the slider body, which accounts for a larger proportion of volume and weight, still uses conventional metal or hard plastic. This design, which uses noise-reducing materials in specific areas, significantly reduces overall material costs, effectively controlling manufacturing costs while ensuring noise reduction performance and structural strength.

[0027] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided. The soft bushing has a bushing hole inside for slidingly engaging the slide rod, and the inner wall of the bushing hole has a lubricating surface that slides in contact with the surface of the slide rod.

[0028] It is understandable that the inner wall of the bushing hole forms a lubricating surface, significantly reducing the sliding friction between the bushing and the slide rod. Low friction ensures that the slider can move more smoothly and easily along the slide rod under the drive of the belt motor, avoiding jamming or obstruction. Furthermore, smooth sliding reduces sharp friction or impact noises caused by uneven friction or jamming. At the same time, low friction means that the driving force required by the belt motor is reduced, resulting in smoother motor operation and potentially lower vibration, indirectly contributing to noise reduction in the entire effects module.

[0029] According to the present invention, a stage light that facilitates the assembly of an effects module and reduces noise is provided. The effects module further includes a conveyor belt and a belt motor connected to the conveyor belt; the rigid slider is connected to the conveyor belt.

[0030] According to the present invention, a stage light for facilitating the assembly of effect modules and noise reduction is provided on the rigid slider, and the conveyor belt is clamped in the belt clamping groove.

[0031] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise has a plurality of protruding ridges formed on the inner wall of the belt clamp groove, and each of the protruding ridges abuts against the conveyor belt.

[0032] According to the present invention, a stage light that facilitates the assembly of an effects module and reduces noise is provided. The effects module further includes a CMY fixing plate for connecting the CMY color swatch, and the CMY fixing plate is fixed on the rigid slider.

[0033] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided. The outer wall of the elastic buckle is formed with a guide arc surface. During the process of axially inserting the elastic buckle into the bushing mounting seat, the elastic buckle contacts the bushing mounting seat through the guide arc surface.

[0034] According to the present invention, a stage light that facilitates the assembly of effect modules and reduces noise is provided, wherein the elastic buckle has several notches that circumferentially surround the soft bushing.

[0035] The main technical effects of this utility model of a stage light with easy-to-assemble effect module and noise reduction are as follows:

[0036] I. Convenient and Efficient Installation: The elastic buckle on the soft bushing allows it to be installed into the bushing mounting seat of the rigid slider via a simple axial press-in method. During the press-in process, the elastic buckle deforms under pressure, smoothly passing through narrow areas, and immediately elastically resets and secures itself upon reaching the predetermined position. This design achieves a "hand-press-in" assembly method, eliminating the cumbersome processes of mechanical press-in and positioning in existing technologies. Therefore, this structure significantly simplifies the assembly process, improves production efficiency, and reduces labor costs.

[0037] II. High Connection Reliability: The elastic buckle forms a secure snap-fit ​​connection with the bushing mounting base after elastic reset. This snap-fit ​​provides a continuous axial locking force, effectively preventing the soft bushing from detaching from the hard slider during use (e.g., during high-speed movement of the effect module or vibration of the lighting fixture). Combined with the limiting structure, the axial position of the bushing within the slider is reliably restricted. Therefore, this structure improves the reliability and stability of the bushing-slider connection, avoids effect module failures caused by bushing detachment or displacement, and extends service life.

[0038] 3. Low Operating Noise: Sliding friction occurs between the soft bushing and the slide bar. Soft materials typically have a low coefficient of friction and good shock absorption and cushioning properties. Compared to direct sliding of hard materials, the soft bushing can more effectively absorb and attenuate the vibration and noise generated during sliding. Therefore, this structure can significantly reduce the noise of the slider sliding along the slide bar during the operation of the effects module, improving the overall quietness of the stage lights.

[0039] IV. Balancing Performance and Cost: The rigid slider ensures the structural strength and dimensional stability required for the effects module, guaranteeing the accuracy of effects piece positioning and avoiding the deformation issues inherent in integrated soft structures. Furthermore, by using soft noise-reducing material only for the bushings, rather than the entire slider, the amount of noise-reducing material used is significantly reduced. Typically, specialized noise-reducing materials are expensive; by using soft materials only at critical sliding contact points, while the slider body uses more economical rigid materials (such as ordinary engineering plastics or metals), this structure effectively controls material costs while achieving noise reduction and reliable connection, resulting in better economic efficiency.

[0040] In summary, the technical solution of this utility model achieves convenient and reliable installation of the bushing and effective noise reduction during sliding by ingeniously combining a rigid slider, a bushing mounting seat, and a soft bushing with elastic buckles. It also reduces costs while ensuring structural strength and dimensional accuracy, thus comprehensively overcoming the shortcomings of the prior art. Attached Figure Description

[0055] like Figures 1 to 8 As shown, this embodiment of a stage light with noise reduction and easy assembly of effect modules includes a base housing 102, a support arm 101 pivotally connected to the base housing 102, and a lamp head 100 pivotally connected to the support arm 101. The lamp head 100 houses a light source 104 and an effect module located in the light emission direction of the light source. In this embodiment, the effect module is a CMY module 103, with a CMY color plate 1 mounted therein serving as the effect piece of the effect module. The CMY module 103 is a key structure for achieving color mixing in the stage light, typically including a CMY color plate 1 and a driving mechanism that drives the CMY color plate 1 to reciprocate into or out of the light source path.

[0056] This embodiment focuses on improving the connection and noise reduction structure between the slider 5, which carries the CMY color plate 1 and slides on the slider 4 in the CMY module 103, and the slider 4.

[0057] Reference Figures 4 to 8 In a preferred embodiment, the CMY module 103 includes a plurality of slide bars 4 and a plurality of sliders 5 respectively disposed on the slide bars 4. To enable movement of the CMY color plate 1, the CMY module 103 also includes a CMY color plate 1 connected to the slider 5, and a transmission mechanism for driving the slider 5 to move along the slide bars 4, such as a conveyor belt 2 and a belt motor 3. The slider 5 is provided with a belt clamping groove 7 for connecting the conveyor belt 2. The inner wall of the belt clamping groove 7 may be formed with a plurality of protruding ridges 8, which can tightly abut or engage with the conveyor belt 2 to ensure reliable transmission.

[0058] Furthermore, the slider 5 is preferably made of a rigid material, such as metal or rigid plastic. Using a rigid material for the slider 5 ensures the overall strength and dimensional stability of the structure, which is crucial for the assembly accuracy and long-term stable operation of the CMY module 103.

[0059] The slider 5 is provided with a structure for mounting bushings, which includes bushing mounting seats 9. Specifically, in this embodiment, the slider 5 is provided with two bushing mounting seats 9, such as... Figure 5 and Figure 7 As shown. Each bushing mounting base 9 has a through hole 15 for accommodating the bushing 10, as shown. Figure 6 As shown.

[0060] The core innovation of this embodiment lies in the fact that the sliding interface between the slider 5 and the slide rod 4 is achieved through two soft bushings 10, and the connection method between the soft bushings 10 and the slider 5 is innovatively designed. The soft bushings 10 are preferably made of soft plastic material, possessing a certain degree of elasticity and shock absorption / noise reduction performance. The soft bushings 10 have bushing holes 14 for slidingly engaging the slide rod 4. The inner wall of the bushing hole 14 can form a smooth sliding contact surface to facilitate smooth sliding with the slide rod 4, and can be formed into a lubricating surface or coated with lubricating material as needed.

[0061] Furthermore, the soft bushing 10 has a structure formed on its outer surface for connection and fixation with the bushing mounting seat 9 of the slider 5. In a preferred embodiment, the soft bushing 10 has an elastic buckle 11 and at least one limiting step, such as the first limiting step 12 and the second limiting step 13 in this embodiment. The elastic buckle 11 is preferably provided at one end of the soft bushing 10. Its structure can undergo elastic contraction deformation under pressure when axially inserted, and after passing through the fitting structure on the inner wall of the through hole 15 of the bushing mounting seat 9 (e.g., a chamfer or fitting groove at the end of the through hole), it elastically returns to its original shape, forming an outward buckle structure, thereby preventing the bushing 10 from coming out of the bushing mounting seat 9 in the direction opposite to the pressing direction.

[0062] Specifically, the outer wall of the elastic buckle 11 is formed with a guide arc surface 16. During the process of axially inserting the elastic buckle 11 into the bushing mounting seat 9, the elastic buckle 11 contacts the bushing mounting seat 9 through the guide arc surface 16. Under the guidance of the arc surface of the guide arc surface 16, the elastic buckle 11 can be inserted into the bushing mounting seat 9 more smoothly.

[0063] In addition, the elastic buckle 11 has several circumferential notches 17 that surround the soft bushing 10, which is equivalent to forming several elastic buckles 11 at the end of the soft bushing 10. Since the notch 17 is opened, the elastic buckle 11 can have a more obvious elastic deformation ability.

[0064] The first limiting step 12 and the second limiting step 13 are located at different axial positions of the flexible bushing 10. When each flexible bushing 10 is axially inserted into the through hole 15 of its respective bushing mounting base 9 and reaches its predetermined installation position, the first limiting step 12 and the second limiting step 13 abut against the opposite end faces of the through hole 15 of the bushing mounting base 9 from opposite directions. Thus, the first limiting step 12 and the second limiting step 13 together provide bidirectional axial limiting for the bushing 10 within the bushing mounting base 9 (i.e., in the direction of the slide rod 4), preventing the bushing 10 from shifting during sliding.

[0065] In a more specific embodiment, such as Figure 8 As shown, the first limiting step 12 can be formed on the snapping surface of the elastic buckle 11, and is respectively disposed at the opposite ends of the flexible bushing 10 with the second limiting step 13, so as to maximize the limiting distance. Furthermore, the first limiting step 12 and the second limiting step 13 can be designed as several protrusions circumferentially surrounding the periphery of the flexible bushing 10 (such as...). Figure 8 (The multiple protruding marks 12 and 13 shown). Compared to continuous annular steps, multiple discrete protrusions can reduce material usage and potentially lower injection molding difficulty while ensuring the limiting effect. To further enhance stability or facilitate mold design, the first limiting steps 12 and the second limiting steps 13 can be staggered in the circumferential distribution direction.

[0066] The installation process in this embodiment is convenient because the soft bushing 10 can be directly installed into the bushing mounting base 9 of the hard slider 5 by hand-pressing it in. The operator only needs to align the bushing 10 with the mounting hole and apply axial pressure. During the pressing process, the elastic buckle 11 at the front end of the bushing 10 will contract and deform inward due to contact with the mating structure of the inner wall of the bushing mounting base 9. After the elastic buckle 11 passes through the mating structure, it immediately returns to its original shape outward by the elasticity of the material, realizing the snap-locking of the bushing mounting base 9. At the same time, the bushing 10 continues to be pressed in until the first limiting step 12 and the second limiting step 13 respectively abut against the two end faces of the through hole 15 of the bushing mounting base 9. At this time, the bushing 10 is installed and axially limited. The whole process does not require any special tools or subsequent fixing processes, such as pressing points or gluing, realizing fast and efficient assembly.

[0067] It is understood that this embodiment uses a soft bushing 10 with elastic buckles 11 and limiting steps (12, 13) to cooperate with a hard slider 5, achieving rapid installation by hand-pressing. Compared with the mechanical pressing and additional fixing of the prior art, this significantly simplifies the assembly process, reduces labor costs, and improves production efficiency. In addition, the elastic buckles 11 provide reliable radial fastening and one-way axial locking, combined with the bidirectional axial limiting provided by the first limiting step 12 and the second limiting step 13, ensuring that the bushing 10 is firmly installed in the slider 5, not easily loosened, detached, or axially displaced, and can remain stable even under the intense movement and vibration of stage lights, improving the operational reliability and lifespan of the CMY module 103. At the same time, the soft plastic bushing 10 directly contacts and slides with the metal slide rod 4, utilizing the damping characteristics and shock absorption capacity of the soft material to effectively absorb the vibration and friction generated during sliding, significantly reducing the noise generated by the CMY module 103 during high-speed operation. Furthermore, the main body of slider 5 is made of metal or hard plastic, retaining its advantages of high strength and dimensional stability, ensuring the overall rigidity and assembly accuracy of CMY module 103. The soft material with noise reduction function is only used in bushing 10, localizing material usage and controlling costs. This avoids the problem of excessively high costs caused by using expensive noise reduction materials for the entire slider in existing technologies, while also overcoming the defects of insufficient strength and easy deformation of all-plastic structures.

[0068] In summary, the noise reduction structure for the stage light CMY module assembly proposed in this embodiment, through the innovative connection method of the soft bushing 10 and the hard slider 5, effectively reduces operating noise while achieving convenient and efficient installation and improving connection reliability. It also takes into account structural strength, dimensional accuracy and manufacturing cost, making it a practical and effective technical improvement solution.
