Description

Technical Field

[0001] This utility model relates to the field of bicycles, specifically a bicycle chain guard bracket that is easy to install. Background Technology

[0002] In bicycles and e-bikes with pedals, power output is achieved through a sprocket driving a chain. To reduce overall weight, many bikes do not come with a chain guard as standard. If consumers require one, it often needs to be installed separately. This requires removing components such as the pedals and sprockets from the bike before the chain guard can be fitted and secured, and then reinstalling the removed components. The entire installation process is complex and difficult for the average consumer to perform, requiring professional assistance and incurring additional time and expense. Utility Model Content

[0005] Furthermore, the clamping ring comprises two semi-rings.

[0006] Furthermore, the two half-rings of the clamping ring are connected at one end by a rotating shaft, and the other end is a locking end. The locking end is provided with a connecting hole, and the locking mechanism is a locking bolt. The two locking ends are connected by the locking bolt.

[0007] Furthermore, the two semi-circular halves of the clamping ring are provided with a connecting groove and a connecting part at one end. The two semi-circular halves cooperate with each other through the connecting groove, and the connecting part is connected by a rotating shaft.

[0008] Furthermore, there are two support rods, and the two support rods maintain a certain angle between them.

[0009] Furthermore, the included angle between the two support rods is greater than or equal to 60°.

[0010] Furthermore, the two support rods are respectively fixed on the two semi-rings.

[0011] Furthermore, the support rod is L-shaped, with one end fixed to the clamping ring and the other end having a bent portion with a fixing screw hole.

[0012] Furthermore, a gasket is provided inside the clamping ring.

[0013] Furthermore, a chamfer is applied to the junction of the outer surfaces of the clamp and the support rod.

[0014] Compared with the prior art, the advantages of this utility model are: This utility model can be used to easily, quickly and conveniently install chain guards, and has a certain size adaptation range, making it highly versatile and able to meet the needs of various vehicle models.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0018] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0019] Please refer to Figure 1-4 This embodiment provides an easy-to-install bicycle chain guard bracket, including a clamping ring 1 and several support rods 2. The clamping ring 1 includes two semi-circular semi-rings, which are connected to form an integral circular clamping ring 1. One end of each semi-ring has a connecting groove and a connecting part, and the other end has a locking end 4. The two clamping rings 1 cooperate with each other through the connecting groove, and the connecting part is connected by a rotating shaft 3. The rotating shaft 3 has limiting structures at both ends to prevent the clamping rings 1 from falling off. After connection, the clamping rings 1 can be quickly opened and closed with the rotating shaft 3 as the hinge point. The locking end 4 has a connecting hole, and the connecting hole is connected by a locking screw. Bolt 5 connects and adjusts the tightness; a gasket is provided inside the clamping ring 1; the support rod 2 has an L-shaped structure, with one end fixed to the clamping ring 1 and the other end having a bent part with a fixing screw hole 6. In this embodiment, the number of support rods 2 is preferably two (or three or more, to accommodate some larger vehicles or vehicles with more rugged road conditions). The support rod 2 is fixed on the clamping ring 1 and maintains a certain included angle. In this embodiment, it is preferred that two support rods 2 are fixed on the same half ring (or they can be fixed on two separate half rings), with an included angle of not less than 60°.

[0020] This embodiment provides a bicycle chain guard bracket that is easy to install. During installation, the clamp 1 is fitted onto the bottom bracket 9 of the frame and locked in place with the locking bolt 5. The circular design allows for free rotation and adjustment at the bottom bracket 9 to achieve any installation angle, thus adapting to the mounting hole positions of different models of chain guards 8. Finally, the chain guard 8 is fixed to the fixing screw hole 6 of the support rod 2 with the fixing bolt 7 to complete the installation. The installation is simple, quick, and convenient. The edges of the clamp 1 and the support rod 2 are treated, such as chamfering, to avoid problems such as scratching hands during installation and disassembly, which could cause safety hazards. The dimensions of the clamp 1 and the support rod 2 can be set very thin, such as only a few millimeters thick, so as not to occupy too much extra space on the surface of the bottom bracket 9, avoiding affecting the installation of other parts and ensuring installation accuracy. Example 2

[0021] The bicycle chain guard bracket provided in this embodiment is easy to install. Compared with the technical solution of embodiment 1, it can be improved as follows: the clamping ring 1 is an elastic metal ring (such as a metal ring in the shape of a pipe clamp), and an anti-slip rubber pad is added to the inner side of the clamping ring 1. It is fixed to the outer wall of the bottom bracket 9 by interference fit to achieve quick assembly. The locking bolt 5 can allow the clamping ring 1 to adapt to bottom brackets 9 of different sizes within a certain range. The anti-slip rubber pad can increase the friction with the contact surface with the frame and prevent loosening during operation.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various changes and modifications can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
