Technical Field

[0001] The invention belongs to the technical field of surface treatment, and in particular relates to a double-locking hanger. Background Art

[0002] In the field of IC equipment manufacturing, most components are small but precise in size, with specific surface requirements for high hardness, insulation, and wear resistance. Some products have through-holes. To ensure the corrosion resistance, wear resistance, and hardness of the product during the anodizing process, the contact area between the hanger and the product must be minimized. Commonly used titanium pins, titanium discs, and titanium screws in existing technologies cannot meet these anodizing process requirements. Summary of the Invention

[0003] In view of this, the utility model discloses a locking type hanger, the specific scheme is as follows:

[0004] A locking type hanger, comprising a fixing fixture, wherein the fixing fixture comprises a locking nut and a screw, wherein the locking nut is provided in two groups, namely a first locking nut and a second locking nut;

[0005] The first locking nut includes a base portion and a tapered portion. The base portion is a cylindrical structure with a vertical through hole with a thread provided in the center thereof. The tapered portion is arranged on the upper top surface of the base portion and is a cone structure. The bottom surface of the tapered portion is connected to the upper top surface of the base portion. The tapered portion is provided with a vertical through hole passing through its apex and connected to the vertical through hole in the base portion. The diameter of the vertical through hole on the tapered portion is larger than the diameter of the vertical through hole on the base portion.

[0006] The screw is a cylindrical rod-shaped structure, and its outer surface is provided with a thread that matches the internal thread in the vertical through hole in the base portion. The base portion of the first locking nut is screwed onto the screw, so that the screw passes through the vertical through hole on the base portion of the first locking nut and the vertical through hole on the tapered portion.

[0007] The second locking nut has the same structure as the first locking nut. The second locking nut is threaded onto the screw rod. The apex of the conical portion of the first locking nut located on the screw rod is arranged opposite to the apex of the conical portion of the second locking nut. The second locking nut can be rotated to adjust the distance between the second locking nut and the first locking nut.

[0008] As a supplement to the technical solution of the present utility model, the tapered portion of the first locking nut is a conical structure.

[0009] As a supplement to the technical solution of the present utility model, the tapered portion of the first locking nut is a pyramid structure.

[0010] As a supplement to the technical solution of the present invention, a guide groove communicating with the vertical through hole on the conical portion is provided on the side surface of the conical portion.

[0011] As a supplement to the technical solution of the utility model, it also includes a hanger body;

[0012] The hanger body is a long straight plate structure with strip-shaped openings arranged along its length. The upper end of the hanger body is provided with a bent portion for hanging;

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0022] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0023] like Figures 1 to 4 As shown, a locking type hanger includes a fixing clamp, which includes a locking nut and a screw 5. The locking nuts are provided in two groups, namely a first locking nut 6 and a second locking nut 4. The material of the locking nuts is TA2.

[0024] The first locking nut 6 includes a base portion 9, a tapered portion 10

[0025] The base portion 9 is a columnar structure with a vertical through hole at its center and a thread on the inner wall of the vertical through hole.

[0026] The conical portion 10 is arranged on the upper top surface of the base portion 9. It is a conical structure. The bottom surface of the conical portion 10 is connected to the upper top surface of the base portion 9. A vertical through hole passing through its vertex is opened on the conical portion 10. The vertical through hole of the conical portion 10 is connected to the vertical through hole of the base portion 9.

[0027] The screw rod 5 is a cylindrical rod-shaped structure, and its outer surface is provided with a thread that mates with the internal thread in the vertical through hole in the base portion 9. The first locking nut 6 is threaded onto the screw rod 5, so that the screw rod 5 passes through the vertical through hole in the base portion 9 of the first locking nut 6 and the vertical through hole in the tapered portion 10. The diameter of the vertical through hole in the tapered portion 10 is larger than the diameter of the vertical through hole in the base portion 9.

[0028] The second locking nut 4 has the same structure as the first locking nut 6 and is connected to the screw rod 5 in the same manner. The apex of the conical portion 10 of the first locking nut 6 located on the screw rod 5 is arranged opposite to the apex of the conical portion 10 of the second locking nut 4, and the second locking nut 4 can be rotated to adjust the distance between the second locking nut 4 and the first locking nut 6.

[0029] During the anodizing process, for products with through holes, when fixing the product, it is necessary to first remove the second locking nut 4 from the screw 5, then put the product on the screw 5, and then screw the second locking nut 4 onto the screw 5. As the second locking nut 4 continues to rotate, the first locking nut 6 and the second locking nut 4 clamp the product. In the clamping state, the tapered portion 10 of the first locking nut 6 and the tapered portion 10 of the second locking nut 4 can contact the end of the through hole of the product, reducing the contact area between the first locking nut 6 and the second locking nut 4 and the product.

[0030] As a preferred technical solution of the present invention, the tapered portion 10 of the first locking nut 6 is a cone. Under this condition, when the through-hole on the product is a circular hole, the upper portion of the tapered portion 10 is inserted into the product through-hole, causing the outer periphery of the tapered portion 10 to contact the outer periphery of the product, sealing the end opening of the product and preventing the electrolyte from entering the through-hole of the product. Therefore, when the tapered portion 10 is a cone, the applicable product through-hole cannot be a circular hole.

[0031] As a supplement to the above technical solution, in order to achieve that when the through hole of the product is a circular hole and the conical portion 10 of the first locking nut 6 is a cone, the electrolyte can smoothly enter the through hole of the product, a guide groove 11 is provided on the side surface of the conical portion 10 and is connected to the vertical through hole on the conical portion 10, so that the electrolyte can smoothly flow into the through hole of the product through the guide groove 11.

[0032] As a preferred technical solution of the present invention, the tapered portion 10 of the first locking nut 6 is a pyramid. When the tapered portion 10 is a pyramid structure, the contact area between the locking nut and the product can be further reduced. For example, when the tapered portion 10 is a pyramid, the first locking nut 6 and the second locking nut 4 are both in point contact with the product. The fewer the number of pyramid side edges, the fewer the number of point contacts with the product. Under this condition, there will be a certain gap between the end of the through-hole of the workpiece and the side surface of the tapered portion 10 of the locking nut, so that when the cross-section of the through-hole of the product is circular or regular polygonal, it can ensure that the electrolyte can smoothly enter the through-hole of the product through the gap. However, it should be ensured that when the cross-section of the through-hole of the product is polygonal, the number of side edges of the tapered portion 10 is different from the number of sides of the cross-section of the through-hole of the product. For example, if the cross-section of the through-hole of the product is triangular, when the tapered portion 10 of the first locking nut 6 is a triangular pyramid, it is easy for the side surface of the locking nut to contact the through-hole of the product when fixing the product, resulting in the electrolyte not being able to smoothly enter the through-hole of the product.

[0033] As a supplement to the above technical solution, when the tapered portion 10 of the first locking nut 6 is a pyramid, in order to ensure the stability of the workpiece fixation, the more side edges the pyramid has, the larger the contact area with the product, and the higher the stability of the workpiece fixation. However, the size of the gap between the through hole end of the workpiece and the tapered portion 10 of the locking nut will be reduced. In order to ensure the quality of anodizing and increase the gap between the through hole of the workpiece and the locking nut, a guide groove 11 connected to the vertical through hole of the tapered portion 10 is provided on the side surface of the pyramid to ensure the quality of anodizing.

[0034] As a supplement to the technical solution of the present utility model, a hanger body 1 is also included.

[0035] The hanger body 1 is a long straight plate structure with strip-shaped openings 2 arranged along its length. The upper end of the hanger body 1 is provided with a bent portion for hanging. The material of the hanger body 1 is TAO.

[0036] The fixing fixture also includes a fixing nut 8 and a fixing screw 7. One end of the fixing screw 7 is fixedly connected to the first locking nut 6. The fixing screw 7 is provided with a thread. The fixing nut 8 is screwed onto the fixing screw 7. When fixing the fixing fixture to the hanger body 1, the fixing nut 8 needs to be removed, and then the fixing screw 7 of the fixing fixture needs to be inserted into the strip opening 2 on the hanger body 1, so that the fixing screw 7 passes through the strip opening 2 of the hanger body 1, and then the fixing nut 8 is screwed onto the fixing screw 7. As the fixing nut 8 is continuously tightened, the fixing nut 8 and the first locking nut 6 clamp the hanger body 1, so that the fixing fixture is fixed to the hanger body 1. The fixing fixture can be provided with multiple groups and arranged along the length direction of the strip opening 2 of the hanger body 1.

[0037] As a supplement to the technical solution of the present invention, the hanger body 1 is further provided with a transfer hole 3 for connecting to another hanger body 1. Specifically, screws can be passed through the transfer holes 3 or strip-shaped openings 2 of the two hanger bodies to connect the two hanger bodies 1 together. Preferably, screws are passed through the transfer holes 3 of the two hanger bodies to increase the number of products that can be clamped and achieve batch processing.

[0038] The above description is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
