Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

Referring to fig. 1 to 5, an oil cup structure, which is mainly used for a range hood, is installed below a filter screen and comprises a cup body 1, a hook 2, a screw 3 and a gasket 4.

The cup body 1 comprises a cup body main body 11 with an upper opening, so that an oil collecting cavity 111 is formed in the cup body main body 11 and is used for collecting grease dropping from components such as a filter screen of the range hood. The cup body 1 is made of a PC material in an injection molding mode, the cup body 1 is required to be provided with the glue injection port in the forming mode according to the injection molding process of the plastic part, the glue injection port can only be placed on an assembly surface because the cup body 1 is an appearance part, the flowing direction of the glue injection port capable of being packaged at the top end is consistent, and the material internal stress in the injection molding process is reduced. Therefore, a connection column 12 protruding upward is formed in the middle of the bottom of the cup body 11 for connecting with the hook 2. The connecting column 12 is a hollow cylindrical structure with a lower opening, and has a top wall 122 and a side wall 123, and the periphery of the top wall 122 and the top of the side wall 123 are in smooth transition. The top wall 122 is provided with a first mounting hole 121. Preferably, the top wall 122 is planar. The cup body 11 and the connecting column 12 are integrally formed, and the wall thickness of at least the top wall 122 of the connecting column 12 in the cup body 1 is uniform, so that the injection molding stress generated in the injection molding process is prevented.

The hook 2 is connected to the connecting column 12. The hook 2 includes a hook main body 21, hangers 22 formed on both sides of the hook main body 21, and positioning posts 23 formed in the hook main body 21. In this embodiment, the hook body 21 is a cylindrical body with a lower opening, preferably a cylinder. The hanging pieces 22 are arranged on two opposite sides of the periphery of the top wall of the hook main body 21 and are used for being connected and fixed with a filter screen of the range hood. The positioning post 23 is disposed within the hook body 21 and extends downwardly from the top of the hook body 21. Preferably, the positioning column 23 is disposed at a middle position in the hook main body 21, and the periphery of the positioning column 23 is connected with the inner peripheral wall of the hook main body 21 through the connecting rib 232. A second mounting hole 231 is formed in the middle of the positioning column 23, the second mounting hole 231 is a threaded hole with internal threads, and the second mounting hole 231 extends upward from the bottom surface of the positioning column 23.

The positioning post 23 can pass through the first mounting hole 121, and the bottom surface of the positioning post 23 is lower than the bottom surface of the top wall 122 of the connecting post 12. The middle of the spacer 4 is opened with a through hole 41 for the screw 3 to pass through, and it is arranged under the bottom surface of the top wall 122 of the connecting column 12.

The screw 3 enters the inside of the connecting column 12 from the bottom opening of the connecting column 12 upwards, and passes through the gasket 4 and the second mounting hole 231 in sequence and then is locked with the positioning column 23, so that the hook 2 and the cup body 1 are fixedly connected. In the locking process, because the bottom surface of the positioning column 23 is lower than the bottom surface of the top wall 122 of the connecting column 12, after the hook 2 and the cup body 1 are connected and fixed, the upper surface of the gasket 4 is in forced abutment with the bottom surface of the positioning column 23, and a gap d is formed between the upper surface of the gasket 4 and the bottom surface of the top wall 122 of the connecting column 12. Therefore, the force for locking the screw 3 is mainly borne by the hook 2 through the gasket 4, the force cannot be transmitted to the cup body 1, and the screw 3 can be prevented from being cracked due to the influence of the locking force in the locking process.
