Description

Technical Field

[0001] This utility model relates to the field of silicone ear hook technology, specifically a high-precision coating and shielding device for silicone ear hooks. Background Technology

[0002] Silicone ear hooks are ear accessories made of silicone material, offering a variety of uses and features. Common uses include securing eyeglasses and preventing them from slipping. For example, large transparent silicone ear hooks, made of highly elastic silicone, are soft and durable, providing a secure hold on glasses, suitable for extended wear, frequent exercise, or those prone to sweating. Silicone ear hooks are also used in headphone design, such as those in liquid silicone-coated ear hook headphones, which can be inlaid with memory wire for improved stability. Some silicone ear hooks are also used as ear ornaments, such as the "elf ear hook," made of soft materials like silicone, with an elegant design that can create the illusion of more upright ears without piercing, thus enhancing facial contours.

[0003] Before coating the silicone ear hooks, certain areas of the ear hooks cannot be coated, so protective devices are needed to cover them. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-precision coating masking and protection device for silicone ear hooks. It has the advantage of being easy to use and solves the problem that some areas of the ear hook cannot be coated before silicone ear hook coating, so a protective device is needed to cover them.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision coating and shielding device for silicone ear loops, comprising a main component, wherein the main component includes:

[0008] The base has a support fixedly connected to its top;

[0009] The base and the support are provided with protective components, the protective components including:

[0010] A cavity is symmetrically formed on the outer wall of the support base;

[0011] A bidirectional lead screw passes through and is rotatably connected within the cavity;

[0012] A motor is mounted on the outer wall of the support base, and the output shaft of the motor is fixedly connected to one end of the bidirectional lead screw.

[0013] A support block is symmetrically and threadedly connected to the outside of the bidirectional lead screw, and the support block is slidably connected to the inner wall of the cavity.

[0014] The protective frame is symmetrically arranged on the opposing surfaces of the support block;

[0015] A support mechanism is provided on the base.

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, this utility model provides a high-precision coating masking and protective device for silicone ear loops, which has the following beneficial effects:

[0027] This protective device is easy to use. First, the center of the silicone ear hook is placed in the slot on the support column. The slot provides basic positioning for the ear hook. Then, an external controller starts the motor, which drives a bidirectional lead screw to rotate. The support blocks threaded onto the bidirectional lead screw bring the protective frames closer together, bringing them into contact with the sides of the ear hook. When the protective frames securely clamp the ear hook, they shield the areas of the ear hook that do not require painting, preventing accidental painting later. This solves the problem of areas on the ear hook that cannot be painted before the silicone ear hook is coated, thus requiring a protective device to shield those areas. Attached Figure Description

[0036] 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.

[0037] Example 1

[0038] See Figure 1-4A high-precision coating and shielding device for silicone ear loops includes a main component 1, which comprises: a base 11 with a support seat 12 fixedly connected to its top; a protective component 2 is provided on the base 11 and the support seat 12, the protective component 2 comprising: a cavity 21 symmetrically opened on the outer wall of the support seat 12; a bidirectional lead screw 22 passing through and rotatably connected to the cavity 21; a motor 23 disposed on the outer wall of the support seat 12, the output shaft of the motor 23 being fixedly connected to one end of the bidirectional lead screw 22; a support block 24 symmetrically and threadedly connected to the outside of the bidirectional lead screw 22, the support block 24 being slidably connected to the inner wall of the cavity 21; a protective frame 25 symmetrically disposed on the opposing surfaces of the support block 24; and a support mechanism 26 disposed on the base 11. The support mechanism 26 includes: a bracket 261, fixedly connected to the bottom of the base 11; an electric push rod 262, disposed on the bracket 261, the output shaft of the electric push rod 262 passing through and extending to the top of the base 11; a groove 263, formed at the top of the base 11; and a support column 264, fixedly connected to the top output shaft of the electric push rod 262. A placement slot 27 is formed at the top of the support column 264.

[0039] In use, the operator first places the center of the silicone ear hook into the placement groove 27 on the support column 264. The placement groove 27 provides basic positioning for the ear hook. Then, the motor 23 is started via an external controller. The motor 23 drives the bidirectional lead screw 22 to rotate. The support block 24 threaded onto the bidirectional lead screw 22 causes the protective frame 25 to move closer together. The protective frame 25 contacts both sides of the ear hook. When the protective frame 25 securely clamps the ear hook, it covers the areas of the ear hook that do not need to be painted, preventing accidental painting later. Next, the output shaft of the electric push rod 262 is shortened, causing the support column 264 to retract into the groove 263, avoiding interference with subsequent painting of the ear hook. At this point, the operator can paint the exposed parts of the ear hook. After the painting is completed, the staff first controls the output shaft of the electric push rod 262 to extend, and the support column 264 supports the ear hook again. Then, the motor 23 is controlled to rotate in the opposite direction, and the protective frame 25 is released from fixing the ear hook. At this time, the ear hook can be removed from the support column 264 to facilitate the covering of the next ear hook.

[0040] Example 2

[0041] An auxiliary function has been added based on Embodiment 1.

[0042] See Figure 1-4The inner wall of the cavity 21 and the facing surfaces of the support block 24 are both provided with telescopic shells 3. The support block 24 is provided with a connecting groove 51, and a connecting block 5 is fixedly connected to the outer wall of the protective frame 25. Bolts 52 are threadedly connected to the support block 24 and the connecting block 5. Protective pads 4 are provided on the facing surfaces of the protective frame 25.

[0043] When the support block 24 moves the protective frame 25 closer together, the telescopic shell 3 fixed on the facing side of the support block 24 retracts, and the telescopic shell 3 fixed on the outer side extends. When the support block 24 moves the protective frame 25 away from each other, the telescopic shell 3 fixed on the facing side of the support block 24 extends, and the telescopic shell 3 fixed on the outer side retracts. The telescopic shell 3 blocks the cavity 21, preventing foreign objects from entering the cavity 21 and causing the bidirectional screw 22 to jam against the support block 24. When the worker paints the ear hook, the exterior of the protective frame 25 is prone to getting dirty. The worker can unscrew the bolt 52 from the support block 24 and the connecting block 5 to separate the support block 24 from the protective frame 25, making it easy to clean the protective frame 25. Alternatively, a protective frame 25 of different shapes can be replaced to achieve different blocking effects on the ear hook. The protective pads 4 on the opposing sides of the protective frame 25 prevent the hard metal or plastic protective frame 25 from directly pinching the soft silicone ear hook. The elastic protective pads 4 can provide greater friction, making the clamping more stable. The slight elastic deformation allows the support block 24 to better adapt to the contour of the ear hook, improving the shielding and sealing performance.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
