Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology and relates to a vehicle drum cover. Background Technology

[0002] The drum cover is an important component of drum brakes. Therefore, it needs to undergo level testing, strength testing, and assembly testing after leaving the factory. Especially for assembly testing, since bicycles and electric vehicles need to use brake cables during braking, the brake cables need to be fixed or limited to prevent them from affecting the use of other components. The existing drum cover cable holes are closed designs, which makes it relatively inconvenient to thread the cable. At the same time, the cable needs to be threaded through the end of the brake cable. Therefore, some cable holes are designed with a small diameter and an opening, but this can easily cause the brake cable to fall off, making it difficult to fix the brake cable and thus meet the usage requirements. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a drum cover that facilitates wire threading.

[0004] The objective of this utility model can be achieved through the following technical solution: A vehicle drum cover, comprising a drum cover body with mounting holes, characterized in that the drum cover body is provided with a threading assembly connected thereto and used for the brake cable to pass through and restrict the position of the brake cable. The threading assembly consists of two threading units, each threading unit including a threading seat and four pulleys. The lower end face of the threading seat is provided with a connecting rod connected thereto and facilitating the connection between the threading seat and the drum cover body. The four pulleys are arranged in pairs to form a pulley row structure, and the two pulley rows are symmetrically arranged along the central axis of the threading seat.

[0005] In the aforementioned vehicle drum cover, the connecting rod has an external thread on the outer peripheral wall at its lower end, and the drum cover body has a threaded hole for mounting the connecting rod.

[0006] In the aforementioned vehicle drum cover, the vertical cross-section of the pulley is arranged in an I-shape, and the lower end face of the pulley is provided with a protrusion that axially protrudes outward and is connected to the wire threading seat.

[0007] Compared with existing technologies, the drum cover of this vehicle has a wire-passing structure, which makes it easier for the brake cable to pass through. Attached Figure Description

[0008] Figure 1 This is a top view schematic diagram of the structure of the drum cover used in this vehicle.

[0009] In the diagram, 1 is the drum cover body; 2 is the wire threading seat; and 3 is the pulley. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, this vehicle drum cover includes a drum cover body 1 with mounting holes. The drum cover body 1 is provided with a threading assembly connected to it and used for the brake cable to pass through and restrict the position of the brake cable. The threading assembly consists of two threading units, each of which includes a threading seat 2 and four pulleys 3. The lower end face of the threading seat 2 is provided with a connecting rod that connects to it and facilitates the connection between the threading seat 2 and the drum cover body 1. The four pulleys 3 are arranged in pairs to form a pulley 3-row structure, and the two sets of pulley 3-rows are symmetrically arranged along the central axis of the threading seat 2. The connecting rod is provided with an external thread on the outer peripheral wall at the lower end. The drum cover body 1 is provided with a threaded hole for the connecting rod to be installed. Through the threaded hole, the threading direction of the threading seat 2 can be changed, thereby facilitating its threading adjustment. The vertical cross-section of the pulley 3 is arranged in an I-shape, and the lower end face of the pulley 3 is provided with an axially outward protrusion that connects to the threading seat 2.

[0012] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0013] Although this document uses terms such as "etc." extensively, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
