Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power-assisted vehicles, and in particular relates to a fender locking structure. Background Art
[0002] The fender is a plate-like structure installed behind the wheel outer frame to block the mud and water brought up by the wheel. The fender is generally fixed to the rear side of the wheel outer frame by bolt connection, so in order to install the fender, existing power-assisted bicycles / bicycles must drill holes or weld connectors at the installation position. This method not only increases the processing steps, but also affects the strength of the installation position of the vehicle body. The installation and disassembly process is also relatively cumbersome. Once the position is broken or damaged, the entire component may need to be replaced or new connectors may need to be re-welded, which has high maintenance costs. Utility Model Content
[0003] The utility model aims to provide a fender locking structure, which does not require drilling or welding of connectors, can be quickly assembled, has a simple structure and does not occupy space.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is to design a fender locking structure, including a front fork, a front fork forged sleeve and a locking piece; the front fork forged sleeve is sleeved on the front end of the front fork; the locking piece is composed of a locking cover piece and a locking spring piece, the locking cover piece is sheet-shaped, and fits into the front end opening of the front fork forged sleeve, the locking spring piece is located on both side edges of the locking cover piece, and is bent toward the rear end face, and the ends of the locking spring pieces on both sides are against the front end limit of the front fork.
[0005] Furthermore, a front fork front end limiter is provided on the front end surface of the front fork, and a sleeve inner wall limiter is provided on the inner wall of the front fork forged sleeve, and the front fork front end limiter and the sleeve inner wall limiter form a limiting relationship.
[0006] Furthermore, a locking connection hole for fixing the fender is provided on the front end surface of the locking cover.
[0007] Furthermore, a reinforcing rib is provided on the rear end surface of the locking cover plate between the locking spring sheets on both sides; a groove is provided between the two ends of the reinforcing rib and between the locking spring sheets on both sides, and a screw hole is provided in the groove; a screw is screwed into the screw hole, and the screw pushes the locking spring sheets on both sides outward.
[0008] The advantages and beneficial effects of the utility model are:
[0009] 1) The front fork and the locking piece can be quickly assembled without additional processing (drilling, tapping or welding of connectors) on the front fork.
[0010] 2) Because there is no need to perform additional processing on the front fork forging tube, it is ensured that its strength will not change due to additional processing.
[0011] 3) Screw the screw into the screw hole to push the locking spring of the locking piece outward, thereby firmly connecting the front fork forging cylinder.
[0012] 4) The fender locking structure has a simple overall design. The front fork and the front fork forged sleeve can be replaced separately if any damage occurs, which reduces maintenance costs and does not take up space.
[0013] 5) The interior of the front fork forging cylinder is relatively closed and has a good dust-proof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 It is an exploded view of the utility model.
[0016] Figure 3 A schematic diagram of a locking device.
[0017] Figure 4 It is a partial cross-sectional view of the utility model.
[0018] Among them, the front fork 1, the front fork front end limit 1-1, the front fork forged sleeve 2, the sleeve inner wall limit 2-1, the locking piece 3, the locking connecting hole 3-1, the locking cover piece 3-2, the locking spring piece 3-3, the screw hole 3-4, the reinforcing rib 3-5, and the screw 4. DETAILED DESCRIPTION
[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example
[0020] The fender locking structure comprises a front fork 1, a front fork forged sleeve 2 and a locking piece 3; the front fork forged sleeve 2 is sleeved on the front end of the front fork 1, the front end surface of the front fork 1 is provided with a front fork front end limit 1-1, the inner wall of the front fork forged sleeve 2 is provided with a sleeve inner wall limit 2-1, and the front fork front end limit 1-1 and the sleeve inner wall limit 2-1 form a limiting relationship to prevent the front fork 1 from moving backward and detaching from the front fork forged sleeve 2.
[0021] The locking piece 3 is composed of a locking cover piece 3-2 and a locking spring piece 3-3. The locking cover piece 3-2 is in the shape of a sheet and fits into the front end opening of the forged sleeve 2 of the front fork. A locking connecting hole 3-1 for fixing the mudguard is provided on the front end face of the locking cover piece 3-2. The locking spring piece 3-3 is located at the two side edges of the locking cover piece 3-2 and is bent toward the rear end face. A reinforcing rib 3-5 is provided on the rear end face of the locking cover piece 3-2 and between the locking spring pieces 3-3 on both sides. Grooves are provided at both ends of the reinforcing rib 3-5 and between the locking spring pieces 3-3 on both sides, and screw holes 3-4 are provided in the grooves. Screws 4 are screwed into the screw holes 3-4.
[0022] The locking cover piece 3-2 fits in the front end opening of the front fork forged sleeve 2, and the ends of the locking spring pieces 3-3 on both sides abut against the front end limit 1-1 of the front fork. Due to the limit formed by the front end limit 1-1 of the front fork and the inner wall limit 2-1 of the sleeve, the front fork 1 is fixed in the front fork forged sleeve 2; continue to tighten the screw 4 to make the locking spring piece 3-3 expand outward, thereby fastening the locking spring piece 3-3 to the inner wall of the front fork forged sleeve 2.
[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
