[0017] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-3In the utility model, a waterproof plastic fastener includes a sleeve 1. The sleeve 1 is made of plastic material, and an annular through groove is opened on the outside of the sleeve 1 to ensure that the sleeve 1 can expand outward, thereby ensuring the fastening effect.

[0020] A threaded connection tube 8 is provided inside the sleeve 1, and a fastening nail 2 is provided inside the threaded connection tube 8. By connecting the fastening nail 2 with the threaded connection tube 8, the outside of the sleeve 1 can expand outward, thereby achieving a fastening effect.

[0021] The top inner wall of the sleeve 1 is fixedly connected with a shielding tube 6, and the top bottom surface of the fastening nail 2 is fixedly connected with a sealing tube 4. When the fastening nail 2 is connected to the threaded connection tube 8, the sealing tube 4 will be sleeved on the outside of the shielding tube 6, which can have a waterproof effect on the fastening nail 2.

[0022] The outer diameter of the top of the fastening nail 2 is adapted to the outer diameter of the casing 1 , which can ensure that the fastening nail 2 is sealed to the top of the casing 1 .

[0023] The bottom surface of the fastening nail 2 is fixedly connected with a sealing gasket 3. The outer diameter of the sealing gasket 3 is larger than the inner diameter of the sleeve 1, and the inner diameter of the sealing gasket 3 is smaller than the inner diameter of the sleeve 1. The use of the sealing gasket 3 further improves the sealing effect of the fastening nail 2 on the top of the sleeve 1.
