Description

Technical Field

[0001] This utility model relates to the field of shielding fixture technology, and in particular to a shielding fixture. Background Technology

[0002] Surgical instruments refer to medical devices used in clinical surgery. In addition to conventional surgical instruments, there are also some specialized instruments. "Medical device surgical tools" refer to tools and equipment that are specially designed, manufactured and used to perform specific functions in surgical procedures or other medical operations. Medical device surgical tools have surface coatings. Some products only need to be coated on part of the surface, and the non-coated areas need to be masked. Conventional masking methods include high-temperature tape masking, masking liquid, aluminum, etc.

[0003] Current masking methods can basically meet people's needs, but there are still some problems, as follows: These traditional masking methods each have their own advantages and disadvantages. Adhesive tape can easily affect the coating performance, using masking liquid is time-consuming, aluminum can easily scratch the product surface, and these methods are all inefficient and have a high defect rate. Utility Model Content

[0004] The purpose of this invention is to provide a shielding fixture to address the shortcomings of existing shielding methods, which suffer from low efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shielding fixture, comprising an outer ring body;

[0006] An inner ring body is installed inside the outer ring body, and a cavity is provided inside the inner ring body;

[0007] The inner ring body has an anti-slip structure installed inside, the outer ring body has a protective structure installed on the outside, and the outer ring body has a disassembly and assembly structure installed inside.

[0008] The disassembly and assembly structure includes an installation cavity inside the outer ring body, an internal thread inside the outer ring body, and an external thread installed on the outer side of the inner ring body.

[0009] In use, the external thread on the inner ring body and the internal thread on the outer ring body first engage with each other, forming a threaded connection. This allows the inner ring body to be tightened inside the outer ring body. After tightening, the stainless steel sheet of the inner ring body and the product can be securely fixed. The inner and outer ring bodies can be fitted onto rod-shaped products. For some rod-shaped products, a special fixture can be used, which can effectively shorten the operation time and improve the yield rate. The structure of the masking fixture is that the inner ring body is made of stainless steel, and the outer ring body is a rotatable structure. By rotating the outer ring body, the stainless steel sheet of the inner ring body and the product can be securely fixed, thus achieving the masking function.

[0010] Furthermore, the inner ring body and the outer ring body form a threaded connection, the outer diameter of the inner ring body is smaller than the inner diameter of the outer ring body, and the inner ring body can be screwed into the outer ring body.

[0011] Furthermore, the protective structure includes a protective layer installed on the outer side of the outer ring, and an anti-slip coating is provided on the outer side of the protective layer, which can protect the outer ring.

[0012] Furthermore, wear-resistant textures are installed on the outer side of the protective layer. These textures are arranged at equal intervals on the outer side of the protective layer, and they can enhance the friction of the protective layer.

[0013] Furthermore, the anti-slip structure includes an inner wall inside the inner ring, a first anti-slip texture inside the inner wall, and a second anti-slip texture inside the inner wall. The anti-slip structure can enhance the friction of the inner wall.

[0014] Furthermore, the second anti-slip texture is arranged at equal intervals inside the inner wall, and the second anti-slip texture and the first anti-slip texture intersect each other. The first anti-slip texture and the second anti-slip texture can enhance the friction of the inner wall.

[0015] Furthermore, the internal and external threads correspond to each other, and the internal and external threads form a threaded connection, allowing the external thread to be screwed into the internal thread.

[0016] The advantages of the shielding fixture provided by this utility model are as follows: When in use, the inner and outer rings can be fitted onto rod-shaped products. For some rod-shaped products, special clamps can be used to effectively shorten the operation time and improve the yield rate. The structure of the shielding fixture is that the inner ring is made of stainless steel with a thickness of 0.3mm and is cylindrical and rotatable. The outer ring is also rotatable. When the outer ring rotates, it can fix the stainless steel sheet of the inner ring to the product tightly, thus achieving the shielding effect.

[0017] By providing an installation cavity on the inner side of the outer ring body, and with the outer diameter of the inner ring body being smaller than the inner diameter of the outer ring body, the inner ring body can be accommodated inside the installation cavity. The external threads on the inner ring body and the internal threads on the outer ring body engage with each other, forming a threaded connection. This allows the inner ring body to be tightened inside the outer ring body. After tightening, the stainless steel sheet of the inner ring body and the product can be firmly fixed, thus achieving a shielding effect. The inner ring body is made of stainless steel with a thickness of 0.3mm, and is cylindrical and rotatable. The outer ring body also has a rotatable structure. Rotating the outer ring body can firmly fix the stainless steel sheet of the inner ring body and the product, achieving a shielding effect. This achieves the purpose of the shielding fixture to enhance the shielding effect. Attached Figure Description
