[0002] The door handle is an indispensable accessory on the door, which has both decorative and functional properties. In order to reduce the use cost of the door handle, some door handles on the market choose to use plastic material for the cover plate. However, the door handle is used frequently, and it is exposed to the air for a long time. When the user rotates the door handle, the first contact position is the cover plate position of the door handle. Therefore, the cover plate is prone to aging and breaking. Once such a problem occurs, many users will choose to replace the entire door handle, resulting in unnecessary economic loss. In addition, the door handle body and the door handle cover plate in the prior art are usually fixed by direct screw connection. However, when the door handle cover plate is aged and worn, the door handle cover plate may slide relative to the door handle body during use, causing inconvenience to the user. SUMMARY
[0003] To solve the above problems, the utility model provides a split handle with plastic decorative cover piece, which can improve the overall strength of the door handle cover plate and the connection stability between the door handle cover plate and the door handle body.
[0004] The technical solution of this utility model is as follows: A split handle with a plastic decorative cover, comprising a door handle body and a door handle cover plate connected to the door handle body. The door handle body includes a connecting part for connecting with a door lock and a handle part connected to the connecting part. The connecting part and the handle part are integrally formed. The door handle cover plate includes a cover plate body and a metal reinforcing member connected to the cover plate body. The cover plate body and the metal reinforcing member are integrally formed by injection molding. The handle part is provided with a limiting protrusion. The door handle cover plate is provided with a first limiting hole. The connecting part is provided with a second limiting hole. The limiting protrusion is T-shaped. The cover plate body is provided with a first limiting groove. When the door handle cover plate is installed on the door handle body, the limiting protrusion and the first limiting groove are positioned correspondingly. The first limiting hole and the second limiting hole are positioned correspondingly. The shape and size of the limiting protrusion and the first limiting groove are adapted to each other. The shape and size of the first limiting hole and the second limiting hole are adapted to each other. The cover plate body is made of plastic. Using the above technical solution, when the door handle cover plate is installed with the door handle body, firstly, the positions of the first limiting groove on the cover plate body and the limiting protrusion on the handle part are aligned. Then, the door handle cover plate is slid a certain distance along the axial direction of the first limiting groove until the door handle cover plate and the door handle body are completely installed together. At this time, since the positions of the first limiting hole and the second limiting hole correspond, and the shape and size of the limiting protrusion and the first limiting groove are matched, and the limiting protrusion is T-shaped, the cover plate body can be prevented from sliding horizontally. At the same time, when the door handle is subsequently installed with the door lock, the connecting shaft on the door lock can be inserted into the first limiting hole and the second limiting hole, thereby preventing the door handle body and the door handle cover plate from sliding vertically relative to each other, further ensuring the overall structural stability of the door handle. In addition, since the cover plate body and the metal reinforcement are integrally formed, the overall strength of the door handle cover plate can be greatly improved, and the service life of the door handle cover plate can be increased. At the same time, compared with using all metal materials for the door handle cover plate, this can greatly reduce the production cost of the door handle.
[0005] A further feature of this invention is that a plurality of first reinforcing ribs are provided at the connection between the metal reinforcing member and the cover plate body, and the first reinforcing ribs are integrally formed with the cover plate body.
[0006] By adopting the above technical solution, since several first reinforcing ribs are provided at the connection between the metal reinforcing member and the cover plate body, the connection stability between the metal reinforcing member and the cover plate body can be further improved, thereby improving the strength and service life of the door handle cover plate.
[0007] A further feature of this invention is that the metal reinforcing member is provided with a second limiting groove, the second limiting groove being positioned corresponding to the first limiting groove, and the position of the metal reinforcing member not coinciding with the position of the first limiting groove.
[0008] By the above technical scheme, since the position of the first limiting groove on the cover plate body is necessarily lower in strength than other positions, by the second limiting groove provided on the metal reinforcing member and corresponding to the position of the first limiting groove, the strength of the position of the inner wall of the first limiting groove can be improved, thereby further improving the service life of the door handle as a whole. The utility model further provides: the metal reinforcing member is provided with a plurality of positioning holes, the cover plate body is provided with a plurality of positioning protrusions, the number of the positioning holes is same as that of the positioning protrusions, the positioning holes and the positioning protrusions are adapted in shape and size and correspond in position one by one.
[0009] By the above technical scheme, since the positioning holes and the positioning protrusions are adapted in shape and size and correspond in position one by one, the connection stability between the cover plate body and the metal reinforcing member can be further improved, and relative sliding between the metal reinforcing member and the cover plate body after aging of the cover plate body is avoided, thereby further improving the strength and service life of the door handle cover plate.
