[0019] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0022] In addition, in the description of the present invention, “a plurality of” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0023] In this utility model, unless otherwise specified or limited, the terms "disposed," "socketed," "connected," "through," and "inserted" should be understood in a broad sense. For example, they can refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0024] See Figure 1 The illustrated structure is a waterproof buckle structure for fixing a steel wire rope for a window lifter, comprising a main rod portion 1, a buckle portion 2 for fixing a steel wire rope being provided at the upper end of the main rod portion 1, a claw portion 3 for docking with a vehicle door being provided at the lower end of the main rod portion 1, a pressure plate 4 being provided at a position of the main rod portion 1 close to the claw portion 3, a sealing ring 5 being provided at the bottom of the pressure plate 4, the claw portion 3 passing through the sealing ring 5, and when the claw portion 3 is buckled into the sheet metal portion of the vehicle door, the sealing ring 5 is squeezed between the pressure plate 4 and the vehicle door sheet metal.

[0025] In the above technical solution, by providing a sealing ring 5, when the claw part 3 is buckled into the door sheet metal, the sealing ring 5 is squeezed between the pressure plate 4 and the door panel, and the sealing ring 5 maintains the sealing performance to prevent water from entering.

[0026] See Figure 1 As shown, the main rod portion 1 is a cross-shaped rod.

[0027] The cross-shaped rod has higher structural strength and is solidly molded for easy injection molding.

[0028] See Figure 1 and Figure 2As shown, the buckle part 2 includes a buckle part 201, the buckle part 201 has an opening 202, a buckle block 203 is provided at one end of the buckle part 201, and a buckle groove 204 is provided at the other end of the buckle part 201 to cooperate with the buckle block 203. When the buckle block 203 and the buckle groove 204 cooperate, the opening 202 is closed. The buckle part 201 and the main rod part 1 are injection molded as a whole.

[0029] In the above technical solution, the buckle block 203 and the buckle groove 204 are matched together. Compared with the semi-open structure in the traditional technology, it can better prevent the steel wire from falling out and has a stronger ability to restrict the steel wire.

[0030] The semi-open structure of traditional technology is as follows Figure 3 .

[0031] See Figure 2 As shown, an inner lining sheet 205 is embedded in the inner wall of the buckle portion 201 , and the inner wall of the inner lining sheet 205 is smooth.

[0032] The steel wire of the lifter is in an active state, and the traditional plastic buckle is easy to break after being worn. The design of the inner lining sheet 205 is adopted in this technical solution to increase the wear resistance.

[0033] The inner lining sheet 205 is a copper sheet or an aluminum sheet.

[0034] See Figure 2 As shown, the pressure plate 4 has an inner conical surface 41, the diameter of which gradually decreases upward, the pawl part 3 includes a center rod 31, and a clamping rod 32 annularly arranged at the bottom of the center rod 31, the upper end of the clamping rod 32 is inclined outward, and a notch groove 33 is provided at the outer position of the upper end of the clamping rod 32, and the sealing ring 5 is positioned at the notch groove 33. When the clamping rod 32 is inserted into the sheet metal hole, the upper end of the clamping rod 32 elastically deforms toward the center rod 31 until the door sheet metal is stuck in the notch groove 33. At this time, the sealing ring 5 is squeezed between the pressure plate 4 and the door panel, and the pressure plate 4 is deformed downward to press the sealing ring 5.

[0035] In the above technical solution, the design of the inner conical surface 41 is adopted, so that when the center rod 31 drives the clamping rod 32 to be inserted along the sheet metal hole, the pressure plate 4 has a downward elastic deformation margin. By utilizing this part of the elastic deformation margin, a reaction force is provided after the clamping rod 32 is fixed to the door sheet metal, so that the claw part 3 is tightened after locking to avoid loosening and producing abnormal noise. The force generated by the deformation of the pressure plate 4 will also increase the force on the sealing ring 5, allowing the sealing ring 5 to be more effectively sealed between the door panel and the pressure plate 4, providing higher sealing performance.
