Description

Technical Field

[0001] The utility model relates to the field of rubber-coated card trays, in particular to a triple-proof liquid silicone rubber-coated card tray. Background Art

[0002] Silicone overmolding involves completely covering the plastic or hardware component with silicone. After molding, the overmolding layer is not exposed. The surface of the silicone overmolding is sprayed with a waterproof, oil-proofing, and stain-resistant liquid to significantly enhance its water, oil, and dirt resistance. This type of silicone overmolding sprayed with waterproof liquid requires support during processing, primarily because the silicone material itself has a certain degree of softness and elasticity. Without support, it may deform or shift during processing, affecting the quality and appearance of the product. Furthermore, silicone may encounter high-temperature vulcanization during processing, which requires controlling the position of the silicone and other hardware components to ensure that the final product's shape and size meet design requirements.

[0003] The existing card tray is composed of an external support frame and an internal limit card column. Although the two can prevent the silicone from moving and deforming during processing, there are still other problems during use, such as the inability to replace the limit card column. Due to the wide variety of products, the corresponding inner diameters of the silicone coating are also different. Since the limit card column and the external support frame are not removable, limit card columns of different specifications need to be equipped with a support frame as a carrier, which increases production costs, has poor flexibility, and is inconvenient to remove the internal silicone coating. Since the silicone coating fits tightly after being placed in the card tray, the friction coefficient of the silicone with the inside of the card tray is high after processing. Personnel need to use tools to knock on the outer surface of the card tray before they can lift it up. The operation is cumbersome and complicated, which increases the workload of personnel. When the inner diameter of the silicone required by the product is large, it can only be passed. In order to solve the above problems, we propose a triple-proof liquid silicone coated card tray. Utility Model Content

[0009] The utility model is further configured as follows: a spring washer is sleeved on the surface of the threaded rod.

[0010] By adopting the above technical solution and providing the spring washer, the fixing nut can be prevented from loosening during and after installation, thereby improving the fastening performance of the threaded rod.

[0015] The utility model is further configured as follows: a guide seat is slidably sleeved on the surface of the connecting rod, and one side of the guide seat is bolted to the support plate through a fixing block.

[0016] By adopting the above technical solution, the connecting rod can be limited by the provision of the guide seat to prevent the connecting rod from tilting during the process of moving up and down.

[0017] The utility model is further configured as follows: a protection frame is bolted to the top of the external support frame, a heat dissipation groove is opened on the front side of the protection frame, and a dustproof net is installed inside the heat dissipation groove.
