Technical Field

[0001] This utility model relates to the field of vacuum coating technology, and in particular to a placement rack for vacuum coating of parts. Background Technology

[0002] Vacuum coating refers to 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 to form a thin film. Vacuum coating mainly includes various methods such as vacuum evaporation coating, vacuum sputtering coating, vacuum ion plating, vacuum beam deposition, and chemical vapor deposition. Usually, the parts are fixed on a rack and then placed in a vacuum environment for coating.

[0003] Chinese Patent Publication No. CN222744400U, published on April 11, 2025, discloses a placement rack for vacuum coating of parts, including a base plate, a turntable movably connected inside the base plate, a cylinder fixedly connected to the upper end of the base plate, a sliding door movably connected to the outside of the cylinder, a motor movably connected inside the base plate and fixedly connected to the lower end of the turntable, a rotating shaft fixedly connected to the upper end of the turntable, four layers of fixing frames evenly distributed outside the rotating shaft, and a locking assembly provided at the front end of the fixing frames. The locking assembly includes a movable cavity opened inside the fixing frame, a connecting rod movably connected inside the movable cavity, a push block fixedly connected to the front end of the connecting rod, and a counterweight fixedly connected to the rear end of the connecting rod.

[0004] Existing vacuum coating placement racks for parts, such as the one described above, can continuously rotate during the coating process by installing components such as connecting rods, push blocks, counterweights, and first springs, making the parts more compact. However, in practice, the number of padlock rods on the support rods and the vertical spacing between the padlock rods are relatively fixed, which increases the limitations of the placement rack. Therefore, it is urgent to propose a corresponding placement rack for vacuum coating of parts to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a placement rack for vacuum coating of parts in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A placement rack for vacuum coating of parts includes a support rod, a padlock rod, a base, and a top seat. A rotating component is fixedly connected to the inner wall of the base, and the output end of the rotating component is fixedly connected to the bottom of the support rod. The top of the support rod is rotatably connected to the inner wall of the top of the top seat via a bearing. A connecting sleeve and a fixing component for locking the vertical position of the connecting sleeve are integrated on the outer side of the support rod. The padlock rod is integrated on the outer wall of the connecting sleeve, and a limiting component for axial limiting of the connecting sleeve is integrated on the outer side of the support rod.

[0008] Preferably, the support rod includes a cut-off rod, a main rod body, and a top rod. Both sides of the vertical end of the cut-off rod are fixedly connected to a protrusion. The two sets of protrusions are respectively fixedly connected to the main rod body and the top rod through two sets of fixing rods.

[0009] Preferably, both the base and the outer wall of the top seat are fixedly connected with mounting plates.

[0010] Preferably, a positioning rod is screwed onto the outer wall of the top seat, and the open end of the positioning rod abuts against the outer wall of the top rod.

[0011] Preferably, the limiting component includes a slider that is fixedly connected to the inner wall of the connecting sleeve, and the slider is slidably connected to the inner wall of the support rod through a vertical groove.

[0012] Preferably, the fixing component includes a protrusion fixedly connected to the top of the connecting sleeve, a locking rod passing through the protrusion, and the locking rod being screwed into the outer wall of the support rod through a screw hole. The screw hole is provided in multiple sets, and the multiple sets of screw holes are distributed vertically.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the base and top seat are fixed to the outer cylinder by the cooperation of the fastening rod and the mounting plate. The vertically moving connecting sleeve is linked to the padlock rod, and the slider slides along the vertical groove, thereby limiting the axial deflection of the connecting sleeve. After the connecting sleeve is aligned with the appropriate height, the locking rod is rotated to engage with the screw hole at that position, thereby fixing the connecting sleeve and the padlock rod. After rotating the fixing rod to separate the protrusion, the cutting rod can be separated independently, so that a notch of a specified height is formed on the main rod. The operator can add or remove a specified number of connecting sleeves and corresponding padlock rods through the notch, which expands the height adjustment and quantity adjustment function of the connecting sleeve and improves the applicability of the placement rack for vacuum coating of parts.

[0015] 2. In this application, before separating the cutting rod, the positioning rod is rotated to engage with the top seat. The axial positioning of the top rod is achieved through the contact friction between the positioning rod and the outer wall of the top rod. This can prevent the top rod from deflecting relative to the main rod after the cutting rod is removed, thus affecting the subsequent reassembly of the cutting rod. This further improves the convenience of using the placement rack for vacuum coating of parts. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A placement rack for vacuum coating of parts includes a support rod 1, a padlock rod 5, a base 7 and a top seat 9. A rotating component is fixedly connected to the inner wall of the base 7. The output end of the rotating component is fixedly connected to the bottom of the support rod 1. The top of the support rod 1 is rotatably connected to the inner wall of the top of the top seat 9 through a bearing 14. A connecting sleeve 2 and a fixing component for locking the vertical position of the connecting sleeve 2 are integrated on the outer side of the support rod 1. The padlock rod 5 is integrated on the outer wall of the connecting sleeve 2, and a limiting component for axial limiting of the connecting sleeve 2 is integrated on the outer side of the support rod 1.

[0025] The base 7 and top seat 9 are fixed to the outer cylinder by the cooperation of the fastening rod and the mounting plate 8. The connecting sleeve 2 is moved vertically, and the connecting sleeve 2 is linked to the padlock rod 5. The slider slides along the vertical groove 6, which can limit the axial deflection of the connecting sleeve 2. After the connecting sleeve 2 is aligned with the appropriate height, the locking rod 4 is rotated to engage with the screw hole 11 at that position, so as to fix the connecting sleeve 2 and the padlock rod 5. After rotating the fixing rod 13 to separate the protrusion 12, the cutting rod 101 can be separated independently, so that a notch of a specified height is formed on the main rod body 102. The operator can add or remove a specified number of connecting sleeves 2 and corresponding padlock rods 5 through the notch, which expands the height adjustment and quantity adjustment function of the connecting sleeve 2 and improves the applicability of the vacuum coating placement rack for parts.

[0026] It should be noted that the padlock rod 5 here directly uses existing technology, and its specific structure and function will not be described in detail here.

[0027] Specifically, such as Figure 2 and Figure 4 As shown, the support rod 1 includes a cut-off rod 101, a main rod body 102, and a top rod 103. Both sides of the vertical end of the cut-off rod 101 are fixedly connected with protrusions 12. The two sets of protrusions 12 are fixedly connected to the main rod body 102 and the top rod 103 respectively through two sets of fixing rods 13, so that the cut-off rod 101 is independently separated, so that a notch of a specified height is formed on the main rod body 102. The operator can add or remove a specified number of connecting sleeves 2 and corresponding padlock rods 5 through the notch. The outer walls of the base 7 and the top seat 9 are fixedly connected with mounting pieces 8, which facilitates the fixing of the base 7 and the top seat 9 to the cylinder.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, a positioning rod 10 is screwed onto the outer wall of the top seat 9, and the open end of the positioning rod 10 abuts against the outer wall of the top rod 103. Before separating the cutting rod 101, the positioning rod 10 is rotated to screw it onto the top seat 9. The axial positioning of the top rod 103 is achieved through the contact friction between the positioning rod 10 and the outer wall of the top rod 103. This can prevent the top rod 103 from deflecting relative to the main rod body 102 after the cutting rod 101 is removed, which would affect the subsequent reassembly of the cutting rod 101. This further improves the convenience of using the vacuum coating placement rack for parts.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, the limiting component includes a slider fixedly connected to the inner wall of the connecting sleeve 2, and the slider is slidably connected to the inner wall of the support rod 1 through the vertical groove 6. While not affecting the vertical movement of the connecting sleeve 2, it limits the axial position of the connecting sleeve 2. The fixing component includes a protrusion 3 fixedly connected to the top of the connecting sleeve 2. A locking rod 4 is inserted inside the protrusion 3. The locking rod 4 is screwed to the outer wall of the support rod 1 through a screw hole 11. There are multiple sets of screw holes 11, and the multiple sets of screw holes 11 are vertically distributed. When the connecting sleeve 2 moves vertically, the connecting sleeve 2 is linked to the padlock rod 5, and the slider slides along the vertical groove 6, thereby limiting the axial deflection of the connecting sleeve 2. After the connecting sleeve 2 corresponds to a suitable height, the locking rod 4 is rotated to screw into the screw hole 11 at that position, thereby fixing the connecting sleeve 2 to the padlock rod 5.

[0030] Working principle: The base 7 and top seat 9 are fixed to the outer cylinder by the cooperation of the fastening rod and the mounting plate 8. The vertically moving connecting sleeve 2 is linked to the padlock rod 5, and the slider slides along the vertical groove 6, thereby limiting the axial deflection of the connecting sleeve 2. After the connecting sleeve 2 is aligned to the appropriate height, the locking rod 4 is rotated to engage with the screw hole 11 at that position, thus fixing the connecting sleeve 2 to the padlock rod 5. After rotating the fixing rod 13 to separate the protrusion 12, the cutting rod 101 can be separated independently, so that a notch of a specified height is formed on the main rod body 102. The operator can use this notch to make a specified number of The addition or removal of the connecting sleeve 2 and the corresponding padlock rod 5 expands the height adjustment and quantity adjustment functions of the connecting sleeve 2, improving the applicability of the placement rack for vacuum coating of parts. Before separating the cutting rod 101, the positioning rod 10 is rotated to engage with the top seat 9. The axial limit of the top rod 103 is achieved by the contact friction between the positioning rod 10 and the outer wall of the top rod 103. This can prevent the top rod 103 from deflecting relative to the main rod 102 after the cutting rod 101 is removed, thus affecting the subsequent re-engagement of the cutting rod 101. This further improves the ease of use of the placement rack for vacuum coating of parts.

[0031] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
