Description

Technical Field

[0001] This utility model relates to the field of door handle processing technology, specifically a vacuum coating equipment for high-gloss door handles. Background Technology

[0002] Door handles are indispensable door accessories, possessing both decorative and functional properties. They are categorized by material, including ceramic, solid wood, metal, glass, crystal, plastic, and alloy. They are also classified by shape, such as single-hole spherical, single-hole strip, or Japanese, modern Chinese, and European styles. Users can choose the material according to their needs. During the manufacturing process, door handles require various auxiliary equipment. Vacuum coating is a method of heating metal or non-metal materials under high vacuum conditions, causing them to evaporate and condense onto the surface of the workpiece (metal, semiconductor, or insulator) to form a thin film. Therefore, vacuum coating equipment is an indispensable auxiliary device in the manufacturing of door handles.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When vacuum coating equipment coats door handles, it generally coats multiple door handles simultaneously. Existing vacuum coating equipment has a fixed structure and cannot adjust the spacing between door handles according to the user's needs, thus significantly reducing the coating effect of the door handles; 2. During vacuum coating, most existing door handles are directly fixed inside the vacuum coating device, resulting in poor coating effects on other parts of the door handle, thus causing uneven coating and significantly reducing the quality of the door handles.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a vacuum coating device for high-gloss door handles, including a housing assembly 1. Two connecting shafts 2 are mounted on both ends of the housing assembly 1 via bearings. Gears 3 are mounted on the top ends of the two connecting shafts 2. Slide grooves 4 are formed on both sides of the two connecting shafts 2. Several positioning grooves 5 are formed on the sides of the two connecting shafts 2 away from the slide grooves 4. Several slots 6 are formed in the middle of one side of each of the two connecting shafts 2. Several mounting seats 7 are provided on the outside of the two connecting shafts 2. Two cavities 8 are formed inside each of the mounting seats 7. One side of each cavity 8 is connected to one end of a spring 9. Pressure plates 10 are provided on the other ends of the two springs 9. Positioning pins 11 are provided on the side of each pressure plate 10 away from the springs 9. Control levers 12 are provided in the middle of one side of each of the mounting seats 7. Several connecting rods 13 are arranged at equal angles on the outside of each of the mounting seats 7. A door handle fixing mechanism 14 is provided at the end of each connecting rod 13 away from the mounting seat 7. Slider blocks 15 are provided on the two inner walls of each of the mounting seats 7.

[0022] In this embodiment, as Figure 1 As shown, the outer casing assembly 1 includes a vacuum coating device body 101, with support legs 102 at each of the four corners of the bottom end of the vacuum coating device body 101, and a motor 103 at the center of the bottom end of the vacuum coating device body 101.

[0023] In this embodiment, as Figure 1 As shown, the two gears 3 are meshed together; this allows for rotation of the direction and angle of the door handle during coating, significantly improving the uniformity of the door handle during coating, thereby increasing the quality of the door handle and meeting the vacuum coating requirements for high-gloss door handles.

[0024] In this embodiment, as Figure 3 As shown, the slide groove 4 and the slider 15 are connected by a sliding connection; this increases the stability of the mounting base 7 during movement, thereby preventing the mounting base 7 from rotating during movement.

[0025] In this embodiment, as Figure 3 As shown, the slot 6 and the control lever 12 are designed with a snap-fit ​​structure; this enables the mounting base 7 to be quickly fixed in position, greatly improving the stability of the mounting base 7 during the fixing process, thereby preventing the mounting base 7 from becoming loose and falling off during use.

[0026] In this embodiment, as Figure 4 As shown, the spring 9 and the pressure plate 10 are symmetrical about the central axis of the connecting shaft 2 with respect to each other; this allows the spacing between the mounting bases 7 to be adjusted according to the user's needs, thereby adjusting the spacing between the door handles and significantly improving the coating effect of the door handles.

[0027] In this embodiment, as Figure 3 As shown, a mounting base 7 and four connecting rods 13 form a group, and there are a total of sixteen groups; this enables the simultaneous coating treatment of multiple door handles, greatly improving the coating efficiency of the door handles during the coating process, thereby increasing work efficiency.

[0028] The usage and advantages of this utility model: The vacuum coating equipment for high-gloss door handles operates as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the vacuum coating device body 101 is first placed in the designated position using the support leg 102. Then, the door handles to be vacuum coated are fixed sequentially using the door handle fixing mechanism. When the spacing between the door handles needs to be adjusted, the mounting base 7 is moved, allowing it to move on the surface of the connecting shaft 2 under the cooperation of the slider 15 and the slide groove 4. At this time, when the positioning pin 11 is pressed by the connecting shaft 2, the positioning pin 11 drives the pressure plate 10 to compress the spring 9. When the positioning pin 11 moves to the positioning groove 5, the spring 9 uses its own elastic structure to drive the positioning pin 11 to engage with the inside of the positioning groove 5 through the pressure plate 10, thereby fixing the mounting base 7. The spacing between the mounting bases 7 can be adjusted according to the user's needs, thereby adjusting the spacing between door handles and significantly improving the coating effect of the door handles. When the mounting base 7 is moved to the desired position, the control lever 12 is rotated to engage with the inside of the slot 6, thus re-fixing the mounting base 7. This double fixation greatly improves the stability of the mounting base 7 during fixation, preventing it from loosening and falling off during use. When the door handle needs to be coated, the motor 103 is started. At this time, the motor 103 drives the gear 3 to rotate through the connecting shaft 2. The meshing transmission between the gears 3 causes the two connecting shafts 2 to rotate synchronously, achieving rotation of the direction and angle of the door handle during coating, greatly improving the uniformity of the door handle during coating, thereby increasing the quality of the door handle and meeting the vacuum coating requirements of high-gloss door handles.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
