Description

Technical Field

[0001] This utility model relates to the technical field of clamps, specifically to a protective structure for a clamp used for coating microparticles. Background Technology

[0002] In the field of audio equipment, microphone sticks, as an important component of headphone microphones or other types of microphones, have a significant impact on the overall quality and market competitiveness of the product due to their appearance quality and protective performance.

[0003] As consumers' demands for product appearance and personalization continue to increase, the appearance treatment of microphone sticks has become a key step in the production process. Among them, spraying the body of the microphone stick is a common treatment method. Spraying can not only give the microphone stick an attractive color and texture, but also improve its wear resistance and corrosion resistance to a certain extent, and extend its service life.

[0004] However, in the actual spraying process, there are many technical challenges. The two ends of the microphone stick usually need to retain their original material or undergo special treatment to ensure that their connection performance with other components and acoustic performance are not affected. For example, one end of the microphone stick may need to be electrically and mechanically connected to the headphone body or other devices, which requires that the surface of that end cannot be covered by the spraying material, otherwise it may affect the stability of the connection and the quality of signal transmission. The other end may be the microphone pickup part, and spraying will change its acoustic characteristics and affect the sound collection effect.

[0005] Therefore, before spraying the microphone stick, both ends must be effectively masked. Currently, common masking methods include using tape or custom-made masking molds. Although using tape is relatively simple and low-cost, it has many drawbacks in practical applications. Tape residue is easily left during application and removal, which not only affects the cleanliness and aesthetics of the microphone stick ends but may also interfere with subsequent assembly processes. Moreover, the application precision of tape is difficult to control, which can easily lead to incomplete or excessive masking, resulting in unstable spraying quality.

[0006] While custom-made masking molds can improve the accuracy and stability of masking, the design and manufacture of these molds require a significant investment of time and money. For small-batch production or situations where product designs change frequently, the molds have poor versatility, which increases the company's production costs and production cycle. In addition, the installation and disassembly of the molds are relatively complex and require professional operators, which also reduces production efficiency to some extent.

[0007] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0008] The existing microfiber spray masking technology mentioned above has many shortcomings and cannot meet the technical problems of efficient, high-quality and low-cost production.

[0009] The technical solution adopted by this utility model to solve its technical problem is: The protective structure for the microphone stick coating fixture includes a protective body and multiple protective caps. The side wall of the protective body is provided with multiple first covering parts for inserting one end of the corresponding microphone stick. The multiple protective caps correspond one-to-one with the multiple microphone sticks, and each of the protective caps is provided with a second covering part for inserting the other end of the corresponding microphone stick.

[0010] As described above, in the protective structure for the micropipe coating fixture, the first covering portion includes a first insertion hole.

[0011] As described above, the protective structure for the microphone stick coating fixture has a first insertion protrusion in the first insertion hole that corresponds to the groove at the first end of the microphone stick.

[0012] As described above, in the protective structure for the micropipe coating fixture, the second cover portion includes a second insertion hole.

[0013] As described above, the protective structure for the microphone roller coating fixture has a second insertion protrusion in the second insertion hole that corresponds to the groove at the second end of the microphone roller.

[0014] As described above, the protective structure for the coating fixture of the microphone stick has a first covering portion on both sides of the protective body.

[0015] As described above, in the protective structure for the microphone stick coating fixture, the thickness of the protective body is greater than the thickness of the microphone stick.

[0016] As described above, the protective structure for the coating fixture of the micropipe has supporting planes at both the top and bottom of the protective body.

[0017] As described above, the protective structure for the microphone stick coating fixture is made of elastic material for both the protective body and the protective cap, and the first and second covering parts are both interference fit with the end of the microphone stick.

[0018] As described above, in the protective structure of the coating fixture for the mimeograph stick, the protective body has a deformation groove recessed inward toward the interior of the protective body between adjacent first covering portions on the same side.

[0019] The beneficial effects of this utility model are as follows: This utility model relates to a protective structure for a coating fixture for microphone rollers, specifically within the technical field of fixtures. It comprises a protective body and multiple protective caps. The protective body has multiple first covering portions on its sidewalls, and each protective cap has a second covering portion. When coating microphone rollers, one end of each microphone roller is first inserted into the first covering portion of the protective body's sidewall, where the first covering portion provides protection. Next, the second covering portion of each protective cap is placed over the other end of the corresponding microphone roller, again providing protection. After these operations, the microphone roller's body is exposed, except for its two ends, which are protected. At this point, the body of the microphone roller can be sprayed, while the two ends, covered by the protective body and caps, are not coated. This batch operation reduces the time spent on covering and removing covering components, improving overall spraying efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] Figure 1 This is a schematic diagram of the protective structure of the micrometer stick coating fixture of this utility model and the structure of the micrometer stick after assembly; Figure 2 This is an exploded view of the protective structure of the micrometer stick coating fixture of this utility model and the micrometer stick after assembly. Figure 3 This is a schematic diagram and a partially enlarged schematic diagram of the protective body of this utility model; Figure 4 This is a schematic diagram of the structure of the microphone stick of this utility model; Figure 5 This is a schematic diagram of the structure of the protective cap of this utility model. Detailed Implementation

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 5 As shown, the protective structure of the microphone stick coating fixture in this embodiment includes a protective body 1 and multiple protective caps 2. The side wall of the protective body 1 is provided with multiple first covering parts 11 for inserting one end of the corresponding microphone stick 3. The multiple protective caps 2 correspond one-to-one with the multiple microphone sticks 3, and each of the protective caps 2 is provided with a second covering part 21 for inserting the other end of the corresponding microphone stick 3.

[0024] Specifically, when it is necessary to paint the microphone sticks 3, one end of each microphone stick 3 is first inserted into the first covering part 11 on the side wall of the protective body 1. The first covering part 11 covers and protects this end of the microphone stick 3, preventing it from being sprayed during the subsequent painting process.

[0025] Next, the second cover 21 of each protective cap 2 is put on the other end of the corresponding microphone stick 3, and the second cover 21 also covers and protects this end of the microphone stick 3.

[0026] After completing the above operations, the microphone stick 3 will be exposed except for the two ends, which will be covered and protected. At this time, the body of the microphone stick 3 can be sprayed. The two ends will not be sprayed with paint because they are covered by the protective body 1 and the protective cap 2.

[0027] Preferably, by providing multiple first covering parts 11 on the protective body 1, one end of multiple microphone rollers 3 can be covered simultaneously; multiple protective caps 2 can also cover the other end of multiple microphone rollers 3 at the same time. Compared with the traditional single covering method, this batch operation greatly reduces the time for covering and removing covering parts and improves the overall spraying efficiency.

[0028] Furthermore, the first cover part 11 and the second cover part 21 provide clear insertion positions for both ends of the microphone stick 3, allowing the operator to quickly and accurately install the microphone stick 3 into the clamp protection structure, reducing the time spent searching for and adjusting the position.

[0029] Furthermore, the first covering part 11 and the second covering part 21 can fit tightly against both ends of the microphone stick 3, effectively preventing paint from splashing onto areas that do not need to be sprayed, ensuring the cleanliness and original state of both ends of the microphone stick 3, and avoiding the impact on its connection performance with other components, acoustic performance, etc. due to spraying onto both ends.

[0030] Since the size and shape of each first masking part 11 and second masking part 21 are uniform, the masking effect on each microphone stick 3 is highly consistent, which makes the quality of the sprayed microphone stick 3 stable and reduces the defect rate caused by non-standard masking.

[0031] The protective body 1 and protective cap 2 of the coating fixture protective structure are usually made of durable materials and can be reused multiple times, which reduces material costs compared to disposable masking materials such as tape.

[0032] The operator only needs to insert the two ends of the microphone stick 3 into the first masking part 11 and the second masking part 21 respectively to complete the installation. After the spraying is completed, the microphone stick 3 can be easily removed from the clamp protection structure. No complicated tools and operating skills are required, which reduces the requirements for the operator's professional skills.

[0033] like Figures 1 to 5As shown, the first covering part 11 in this embodiment includes a first insertion hole. When it is necessary to protect the microphone stick with coating, the operator directly inserts one end of the microphone stick into the first insertion hole of the first covering part 11. The inner wall of the first insertion hole can fit tightly with the outer peripheral wall of the microphone stick to form a relatively sealed space. When the coating operation is carried out, the paint is sprayed onto the surface of the microphone stick in the form of a spray. Due to the obstruction of the first insertion hole, the paint cannot enter the inside of the insertion hole, thereby effectively protecting the inserted end of the microphone stick and preventing that end from being covered by the paint.

[0034] Preferably, the structure of the first insertion hole is very simple. Compared with some complex covering structures, its manufacturing process is relatively easy. When producing the protective body 1, the first insertion hole can be formed by common processing methods such as drilling and injection molding. It does not require complex mold design and manufacturing process, which reduces the production difficulty and cost.

[0035] Due to its simple structure, it is relatively easy to repair if the first socket is damaged during use. For example, if the inner wall of the first socket is slightly worn, its performance can be restored by simple polishing or replacement of related parts.

[0036] The first insertion hole provides a precise insertion position for the microphone stick. The operator only needs to insert the microphone stick into the hole to ensure that the microphone stick is fixed and accurate on the protective body. This helps to ensure that the body of the microphone stick is evenly exposed during the coating process, resulting in a more consistent spraying effect and improving the coating quality of the product.

[0037] Precise positioning eliminates the need for operators to make excessive adjustments and alignments when installing the microphone stick, enabling them to quickly assemble the microphone stick with the protective body and improving overall work efficiency.

[0038] Furthermore, the inner wall of the first insertion hole can fit tightly against the outer peripheral wall of the microphone roller, forming a good sealing effect. This tight fit can effectively prevent the intrusion of paint. Even under high-pressure spraying and other conditions, it can minimize the possibility of paint entering the insertion hole and ensure the cleanliness of the microphone roller insertion end.

[0039] The shape and size of the first insertion hole can be designed according to the different shapes (such as round, square, etc.) and sizes of the microphone stick to ensure a tight fit in various situations, and has strong versatility and adaptability.

[0040] Because the structure of the first insertion hole is simple, relatively little material is required during manufacturing, which reduces material costs. At the same time, when selecting materials, relatively inexpensive materials such as plastic, rubber, or silicone can be used to make the protective body according to actual needs, further reducing costs.

[0041] During use, the first connector does not require additional tools or materials to cover it, reducing usage costs. Moreover, it is durable and can be reused multiple times, resulting in lower costs per product.

[0042] like Figures 1 to 5 As shown, the first insertion hole in this embodiment is provided with a first insertion protrusion 12 corresponding to the first end groove 31 of the microphone stick 3.

[0043] When the microphone stick 3 needs to be installed with the first cover part 11, the operator aligns the first end of the microphone stick 3 with the first insertion hole of the first cover part 11. During the insertion process, the first insertion protrusion 12 in the first insertion hole will approach the groove 31 at the first end of the microphone stick 3. As the insertion action proceeds, the first insertion protrusion 12 gradually embeds into the groove 31 at the first end. By utilizing the cooperation between the protrusion and the groove, the two are accurately positioned and tightly connected. In subsequent operations (such as painting operations), this cooperation relationship can ensure that the microphone stick 3 is stably fixed in the first cover part 11 and will not easily shake or shift.

[0044] Preferably, the corresponding design of the first insertion protrusion 12 and the first end groove 31 provides a clear positioning reference for the installation of the microphone stick 3. When installing, the operator only needs to align the protrusion with the groove and insert it to ensure that the microphone stick 3 is accurately positioned in the predetermined position of the first covering part 11, avoiding uneven coating or other problems caused by installation position deviation, and improving the assembly accuracy and consistency of the product.

[0045] Precise positioning makes the assembly process simpler and faster. Operators do not need to spend time adjusting the position of the microphone 3, reducing the trial and error process, thereby improving the overall assembly efficiency and reducing labor costs.

[0046] Furthermore, after the first insertion protrusion 12 is embedded into the first end groove 31, a mechanical locking structure is formed, which can effectively restrict the movement of the microphone roller 3 within the first covering part 11. During the painting operation, when affected by factors such as the impact of paint spraying and external vibration, this connection method can ensure that the microphone roller 3 remains stable and will not shake or shift, thus ensuring the stability of the painting quality.

[0047] Furthermore, the combination of protrusions and grooves increases the strength and reliability of the connection. Even in harsh working environments, such as production lines with high vibration, the connection between the microphone 3 and the first cover 11 will not loosen, thus extending the product's service life.

[0048] When the first insertion protrusion 12 and the first end groove 31 are tightly fitted, the sealing between the first covering part 11 and the microphone roller 3 can be further enhanced. During the coating process, this good sealing can effectively prevent the paint from entering the first end of the microphone roller 3 from the connection gap between the two, better protect the part of the microphone roller 3 that does not need to be coated, and improve the protective effect of the product.

[0049] Furthermore, the design of the first insertion protrusion 12 and the first end groove 31 provides clear identification marks for operators. During the assembly process, operators can quickly identify the installation direction and position of the microphone 3 by observing the position of the protrusion and groove, thus avoiding production accidents or product quality problems caused by incorrect installation.

[0050] For new employees or those unfamiliar with the operating procedures, these clear identification marks help them master the operating methods more quickly, improve the accuracy and standardization of operations, and reduce the impact of human factors on product quality.

[0051] like Figures 1 to 5 As shown, the second masking part 21 in this embodiment includes a second insertion hole. The second insertion hole of the second masking part 21 is mainly used to cooperate with the second end of the microphone stick 3. When it is necessary to cover and protect the microphone stick 3, the operator aligns the second end of the microphone stick 3 with the second insertion hole and then applies a certain external force to push the microphone stick 3 into the hole. During the insertion process, the inner wall of the second insertion hole will fit tightly with the outer peripheral wall of the second end of the microphone stick 3. By utilizing the friction between the two and the possible interference fit, the connection and fixation between the second masking part 21 and the microphone stick 3 are achieved. In subsequent painting and other operations, the second masking part 21 stably covers the second end of the microphone stick 3 through this connection method, which plays the role of protecting this part from being painted.

[0052] The design of the second insertion hole makes the installation process of the microphone stick 3 and the second cover part 21 simple and quick. The operator only needs to insert the microphone stick 3 into the second insertion hole to complete the connection. There is no need to use complicated tools or perform cumbersome operations, which greatly improves the assembly efficiency and is suitable for large-scale production operations.

[0053] When it is necessary to inspect, repair, or replace the second cover 21 of the microphone stick 3, it can be easily separated simply by pulling the microphone stick 3 out of the second insertion hole. This convenient disassembly method reduces maintenance time and costs and improves the maintainability of the equipment.

[0054] Furthermore, the second insertion hole can be precisely designed according to the size and shape of the second end of the microphone stick 3, ensuring a tight fit after insertion and achieving precise coverage of that part. During the coating process, it effectively prevents paint from adhering to the second end of the microphone stick 3, ensuring the cleanliness and integrity of the parts that do not need to be coated, and improving the quality and appearance of the product.

[0055] In addition to preventing paint intrusion, the design of the second insertion hole can also protect the second end of the microphone 3 from other external factors, such as dust and moisture, thus extending the service life of the microphone 3.

[0056] The second insertion hole can be designed according to different specifications and sizes of microphone sticks 3, so that the second cover part 21 has strong versatility and adaptability. In the production process, for different models of microphone sticks 3, only the second cover part 21 with the appropriate second insertion hole needs to be replaced, which reduces production costs and management difficulty.

[0057] Regardless of the coating process used, such as spraying or dipping, the design of the second insertion hole ensures the connection stability between the second cover part 21 and the microphone roller 3, ensuring good protection under different process conditions.

[0058] The design of the second insertion hole is relatively simple and the manufacturing process is not complicated. Therefore, the production cost of the second cover part 21 can be reduced. At the same time, the simple structure also reduces the probability of failure and improves the reliability and stability of the product.

[0059] This design eliminates the need for additional complex connecting components, resulting in a smaller overall size of the second cover 21 and less space occupation. In environments with limited space, such as production workshops, this design helps improve space utilization and facilitates equipment layout and management.

[0060] like Figures 1 to 5 As shown, the second insertion hole in this embodiment is provided with a second insertion protrusion 22 corresponding to the groove 32 at the second end of the microphone stick 3. When the second cover part 21 needs to be installed on the second end of the microphone stick 3, the operator aligns the second end of the microphone stick 3 with the second insertion hole. During the insertion process, the second insertion protrusion 22 in the second insertion hole will precisely match the groove 32 at the second end of the microphone stick 3. As the insertion action proceeds, the second insertion protrusion 22 gradually engages in the groove 32. The tight fit between the protrusion and the groove provides additional positioning function on the one hand, ensuring that the second cover part 21 and the microphone stick 3 are accurately connected; on the other hand, the mutual holding between the two increases the stability and firmness of the connection between the second cover part 21 and the microphone stick 3, preventing relative displacement or separation of the two in subsequent operations (such as shaking or moving during the painting process).

[0061] The corresponding design of the second insertion protrusion 22 and the groove 32 provides a precise positioning reference for the installation of the second cover part 21 and the microphone 3. During assembly, the operator can quickly and accurately install the second cover part 21 into the correct position by observing the alignment of the protrusion and the groove, avoiding problems such as poor covering effect or affecting subsequent processes due to installation position deviation, and ensuring the assembly quality of the product.

[0062] During mass production, the second insertion protrusion 22 of each second cover part 21 and the groove 32 of the microphone 3 can achieve standardized matching, which makes the assembly process and result of each product highly consistent, reduces assembly errors caused by human factors, and helps to improve production efficiency and product quality stability.

[0063] In actual use, especially during operations such as painting, the microphone stick 3 may be subjected to various external forces, such as airflow impact and equipment vibration. After the second insertion protrusion 22 is inserted into the groove 32, it can effectively limit the relative sliding and rotation between the second covering part 21 and the microphone stick 3. Even if it is subjected to certain external force interference, the two can maintain a relatively fixed positional relationship, ensuring that the second covering part 21 always stably covers the second end of the microphone stick 3, thus playing a good protective role.

[0064] Specifically, the combination of the protrusion and the groove increases the strength of the connection. This additional holding structure can withstand greater tension and torque, reducing the risk of the second cover 21 falling off during use and improving the reliability and durability of the product.

[0065] Because the second masking part 21 is more stably connected to the microphone roller 3, it can better maintain the masking state of the second end of the microphone roller 3 during the coating process, avoiding gaps or displacement of the masking part due to weak connection, thereby ensuring that the paint will not seep into the area that does not need to be coated, further improving the protective effect on the second end of the microphone roller 3, and ensuring the appearance quality and performance of the product.

[0066] For operators, the design of the second insertion protrusion 22 and groove 32 provides clear visual and tactile identification. During the assembly process, the correct installation direction and position of the second cover 21 and the microphone 3 can be quickly identified by observing or touching these features, reducing the possibility of operational errors and improving the efficiency and accuracy of assembly.

[0067] Furthermore, by checking whether the second insertion protrusion 22 is correctly inserted into the groove 32 and the gap between the two, it is possible to quickly determine whether the connection quality between the second cover part 21 and the microphone 3 meets the requirements, which facilitates the timely detection and handling of unqualified products.

[0068] like Figures 1 to 5As shown, the protective body 1 in this embodiment has a first covering part 11 on both sides. During the spraying operation, the microphone rollers are installed on the protective body 1. Since the protective body 1 has a first covering part 11 on both sides, each first covering part 11 can clamp a certain number of microphone rollers. When the spraying operation is performed, the spray gun or other spraying equipment sprays the microphone rollers clamped on the protective body 1 according to a preset program or path.

[0069] Preferably, the first masking portions 11 on both sides are symmetrically arranged. Because the microphone rollers are symmetrically distributed on both sides, the spray gun can spray the microphone rollers on both sides simultaneously during one spraying process. This is equivalent to processing twice the number of microphone rollers in the same amount of time, thereby completing the spraying work of more microphone rollers without increasing the additional spraying time.

[0070] Traditional clamping methods can only clamp the microphone rollers on one side. After completing the coating on one side, the clamping needs to be readjusted or the clamping device replaced to coat the microphone rollers on the other side, which increases the number of coating operations and the time required. The symmetrical structure, however, allows both microphone rollers to be coated simultaneously, handling twice the number of rollers in a single coating operation. This significantly reduces the total number of coating operations, thereby substantially shortening the overall coating process time and increasing the output per unit time.

[0071] In large-scale production, optimizing the production process is crucial for improving efficiency. The symmetrical structure design makes the spraying process more compact and efficient, reducing equipment downtime and operator waiting time. Operators can perform continuous spraying operations after one setup, avoiding frequent setup and adjustment operations and improving the continuity and smoothness of the production process.

[0072] Because the spraying time is shortened, the usage time of the spraying equipment is also reduced accordingly. This means that the wear and tear on the equipment and energy consumption are reduced, the service life of the equipment is extended, and energy consumption and equipment maintenance costs are also reduced.

[0073] In the same amount of time, operators can complete more spraying work on the spraying rollers, which is equivalent to improving labor efficiency. This means that when producing the same number of products, the number of operators required can be reduced or more products can be produced with the same staffing, thereby reducing labor costs.

[0074] In the quality inspection process, the symmetrical structure makes the inspection work more convenient and accurate. Because the spraying rollers on both sides have similar spraying characteristics, inspectors can more easily compare and judge whether the spraying quality meets the standards. At the same time, it also facilitates the monitoring and adjustment of the spraying process, and timely detection and resolution of potential quality problems.

[0075] Furthermore, the symmetrical clamping of the nozzle rollers on both sides can make the weight distribution on the protective body 1 more uniform, reducing equipment shaking or displacement caused by weight imbalance. This helps to improve the stability of the equipment during the spraying process, ensures the accurate relative position between the spray gun and the nozzle roller, and thus improves the precision and quality of the spraying.

[0076] Furthermore, a uniform weight distribution can reduce the mechanical stress on the protective body 1 and related clamping components, which helps to extend the service life of the equipment, reduce the risk of component damage and failure caused by stress concentration, and improve the reliability and stability of the equipment.

[0077] like Figures 1 to 5 As shown, the thickness of the protective body 1 in this embodiment is greater than the thickness of the microphone 3.

[0078] When the thickness of the protective body 1 is greater than the thickness of the nozzle roller 3, the nozzle roller 3 is placed on the protective body 1, which supports the nozzle roller 3. During the spraying process, there is a certain gap between the nozzle roller 3 and the spraying line (such as a conveyor line for transporting sprayed objects). This prevents the nozzle roller 3 from directly contacting the spraying line. Because the spraying line may retain some paint, dust or other impurities during long-term use, if the nozzle roller 3 directly contacts the spraying line, these contaminants may adhere to the surface of the nozzle roller 3, thereby affecting the spraying quality and causing poor contamination. By supporting the nozzle roller 3 with the protective body 1, the nozzle roller 3 is effectively isolated from the spraying line, ensuring the cleanliness of the nozzle roller 3 surface and laying the foundation for a good subsequent spraying effect.

[0079] When spraying both sides of the microphone roller 3, the thick protective body 1 provides the operator with sufficient operating space and convenient leverage points. The operator can easily hold the protective body 1 to flip the microphone roller 3, allowing the other side of the microphone roller 3 to be sprayed smoothly. Moreover, during the flipping process, the protective body 1 can stably support the microphone roller 3, reducing the risk of the microphone roller 3 falling or shifting.

[0080] During the spraying process, when the nozzle roller 3 is placed on the protective body 1, the protective body 1 supports the nozzle roller 3, making it relatively stable and allowing it to better receive the paint sprayed from the spray gun. This stable support also facilitates uniform spraying of the nozzle roller 3 according to the preset path and parameters. When spraying both sides, the convenient and stable flipping operation ensures that both sides receive sufficient and uniform spraying, avoiding problems such as missed areas and uneven thickness, thus resulting in a more uniform and consistent spraying quality for the entire nozzle roller 3.

[0081] This design avoids contamination issues caused by contact between the micropipe 3 and the spraying line, significantly reducing the product defect rate due to contamination. In actual production, contamination is a major factor affecting product quality. If it cannot be effectively addressed, it can lead to a large number of defective products. This design ensures that more micropipe 3 products meet quality standards after spraying, improving the product yield and reducing cost losses due to defective products.

[0082] The design, which facilitates flipping and spraying on both sides, makes the spraying operation smoother and more efficient. Operators can quickly and accurately complete the spraying of both sides of the microphone roller 3, reducing time wastage and operational errors during the flipping process. This design enables more microphone roller 3 spraying tasks to be completed in a shorter time, improving production efficiency per unit time and helping companies meet market demands more quickly.

[0083] Uniform spraying gives the Migun 3 surface a good gloss and texture, while also enhancing the adhesion and protective properties of the coating. This design effectively avoids problems such as uneven coating, such as local thickness being too thin or too thick, and inconsistent colors, thus improving the overall quality and aesthetics of the product and enhancing its competitiveness in the market.

[0084] like Figures 1 to 5 As shown, the top and bottom of the protective body 1 in this embodiment are provided with supporting planes 13. The supporting planes 13 of the protective body 1 are mainly used to contact the spraying line (such as the platform of the conveyor equipment). When the protective body 1 is placed on the spraying line, the supporting planes 13 and the spraying line form a large area of ​​contact. According to the principle of stability of plane contact, this large area of ​​contact can increase the friction force and prevent the protective body 1 from sliding or shifting during the movement of the spraying line. At the same time, the supporting planes 13 can evenly distribute the total weight of the protective body 1 and the mittens 3 placed on it to the spraying line, avoiding damage to the spraying line due to excessive local pressure and ensuring the smooth operation of the entire spraying process.

[0085] The support plane 13 ensures the stability of the nozzle roller 3 during the spraying process, enabling the spray gun to spray the nozzle roller 3 more accurately. The stable support can avoid problems such as uneven spraying and missed spraying caused by the shaking of the nozzle roller 3, thereby improving the spraying quality of the nozzle roller 3, making the product more beautiful, and enhancing the adhesion and protective performance of the paint.

[0086] Furthermore, the supporting plane 13 ensures the stable movement of the protective body 1 on the spraying line. In large-scale spraying production, the spraying line usually operates continuously. If the protective body 1 cannot be stably placed on the spraying line, it may collide with other objects during movement or experience positional deviations, affecting the normal operation of the entire production process. The stable support provided by the supporting plane 13 reduces malfunctions and unexpected situations during production, improving the stability and continuity of production.

[0087] like Figures 1 to 5 As shown, both the protective body 1 and the protective cap 2 in this embodiment are made of elastic material, and the first covering part 11 and the second covering part 21 are both interference fit with the end of the microphone stick.

[0088] Specifically, elastic materials have the property of deforming under stress and returning to their original shape after the external force is removed. The protective body 1 and the protective cap 2 are made of elastic material. When the end of the microphone stick is placed into the first cover part 11 and the second cover part 21, the elastic material will be compressed and undergo elastic deformation due to the interference fit. This deformation will generate a reverse elastic force, which will act tightly on the end surface of the microphone stick, so that the first cover part 11 and the second cover part 21 are in close contact with the end of the microphone stick.

[0089] When the end of the spray nozzle is inserted, the protective body 1 and the protective cap 2 of the elastic material undergo elastic deformation, thereby generating radial pressure. This pressure provides sufficient friction to firmly fix the protective body 1 and the protective cap 2 to the end of the spray nozzle, preventing them from loosening or falling off during the spraying process.

[0090] The tight interference fit ensures that there is no gap between the first masking part 11 and the second masking part 21 and the end of the nozzle roller, which can effectively prevent paint from splashing onto the end of the nozzle roller that does not need to be sprayed during the spraying process. This ensures that the original performance and appearance of the nozzle roller end are not affected by the paint.

[0091] Since the protective body 1 and the protective cap 2 can be firmly fixed to the end of the nozzle roller, they will not shake or shift during the spraying process. This allows the spray gun to spray the parts of the nozzle roller that need to be sprayed more accurately. This helps to improve the uniformity and consistency of the spraying, and reduces spraying defects caused by loose protective parts, such as missed spraying and dripping, thereby improving the overall spraying quality of the nozzle roller.

[0092] The use of elastic materials and interference fit design allows the protective body 1 and protective cap 2 to be reused. After the spraying is completed, they can be removed from the end of the spraying roller and reused for the next spraying operation after simple cleaning. Compared with disposable protective parts, this reusable design can greatly reduce the production cost of enterprises and improve the utilization rate of resources.

[0093] The properties of the elastic material make it relatively easy to install and remove the protective body 1 and the protective cap 2. Operators do not need to use complicated tools; they only need to apply a certain external force to put them on the end of the vibrating stick or remove them from the end. This not only improves the operator's work efficiency but also reduces the difficulty and labor intensity of the operation.

[0094] Because the elastic material has a certain deformation capacity, even if there is a certain tolerance in the size of the end of the microphone roller, the first covering part 11 and the second covering part 21 can adapt to these size differences through elastic deformation and still achieve a good interference fit. This makes the protection design more versatile and adaptable, and can meet the spray protection needs of different batches and different specifications of microphone rollers.

[0095] like Figures 1 to 5 As shown, in this embodiment, the protective body 1 has a deformation groove 14 recessed inward towards the interior of the protective body 1 between adjacent first covering parts 11 on the same side. This allows for a certain deformation space when the first covering parts 11 are inserted.

[0096] When the first cover part 11 is inserted into the end of the microphone stick, due to the interference fit, the first cover part 11 will be deformed by the pressure from the end of the microphone stick. The deformation groove 14 is located between adjacent first cover parts 11 on the same side and is recessed inward towards the protective body 1. It provides an additional space for the deformation of the first cover part 11. When the first cover part 11 is compressed, its excess material can move into the deformation groove 14, thereby relieving the pressure on the first cover part 11 and enabling the first cover part 11 to deform more smoothly to adapt to the interference fit with the end of the microphone stick.

[0097] During the deformation of the first covering part 11, the deformation groove 14 also plays a role in balancing the stress distribution. Without the deformation groove 14, the stress on the first covering part 11 may be concentrated in certain parts, resulting in excessive local stress, which may easily damage the material or cause cracks. The presence of the deformation groove 14 allows the stress to be distributed more evenly in the relevant parts of the first covering part 11 and the protective body 1, avoiding the occurrence of stress concentration and ensuring the overall structural stability of the protective body 1.

[0098] The deformation space provided by the deformation groove 14 makes it easier for the first cover part 11 to be inserted into the end of the microphone stick. The operator does not need to apply too much external force to fit the first cover part 11 onto the end of the microphone stick. This not only improves the efficiency of installation, but also reduces the risk of damaging the protective body 1 or the end of the microphone stick due to excessive force during installation.

[0099] Since there may be certain tolerances in the dimensions of different microphone stick ends, the design of the deformation groove 14 allows the first cover part 11 to better adapt to these dimensional differences. Even if the size of the microphone stick end is slightly larger than the standard size, the first cover part 11 can achieve a tight fit with the microphone stick end by deforming into the deformation groove 14. This enhances the adaptability of the protection body 1 to microphone sticks of different sizes, improves the versatility of the protection body 1, and reduces the cost for enterprises to customize multiple specifications of protective parts due to product size differences.

[0100] By balancing the stress distribution, the damage to the material caused by stress concentration is reduced. The deformation groove 14 helps to extend the service life of the protective body 1. During multiple installation and disassembly processes, the protective body 1 can withstand more stress cycles without damage, thus allowing it to be reused multiple times.

[0101] Because the first masking part 11 can more smoothly achieve an interference fit with the end of the microphone roller and can better adapt to the ends of microphone rollers of different sizes, this ensures a tight fit between the first masking part 11 and the end of the microphone roller. During the spraying process, it can more effectively prevent paint from splashing onto the ends of the microphone roller that do not need to be sprayed, improve the protection effect on the end of the microphone roller, and ensure the quality of the spraying operation and the overall performance of the microphone roller.

Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
