Description

Technical Field

[0001] The utility model relates to the technical field of bicycle frames, and more particularly to an improved bicycle release frame component. Background Art

[0002] A bicycle is a two-wheeled vehicle powered by human power. Its structure usually consists of a frame, wheels, handlebars, a seat, a transmission system, and a braking system.

[0003] A bicycle drop-out frame component is a component used to connect different parts of a bicycle frame. It has a "drop-out" function, allowing additional structures on the frame to be disassembled and assembled, such as installing a rear seat or a storage basket, to increase the functionality of the bicycle.

[0004] However, existing bicycle detachable frame components are usually installed with screws or bolts for the rear seat or the storage basket, which is very inconvenient when people are installing or detaching the frame components. When the storage basket needs to be installed, people need to use handheld tools to detach the rear seat, and when the storage basket needs to be installed, people need to remove the rear seat. In actual use, people often have multiple needs, and frequently using handheld tools for disassembly will undoubtedly cause great trouble in actual use. This makes it difficult for people to quickly and effectively disassemble or install appropriate additional structures under different needs, thereby affecting the installation and disassembly efficiency of the bicycle additional structure.

[0005] Secondly, existing bicycles are often equipped with certain lumbar support components to increase the comfort of the rider. However, the existing lumbar support components are inconvenient to adjust and are also cumbersome to remove when not needed, which undoubtedly brings great inconvenience to actual use.

[0006] In view of this, we propose an improved bicycle dropout frame member. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of the present utility model is to provide an improved bicycle dropout frame component to solve the problems raised in the above background technology.

[0009] 2. Technical solution

[0010] An improved bicycle release frame element includes a frame body, a seat is sleeved on the top of the frame body, a backrest adjustment component and an installation release component are also provided on the top of the frame body, the backrest adjustment component includes a fixing sleeve, a lifting rod is sleeved inside the fixing sleeve, and the installation release component includes a support seat, a mounting plate is clamped inside the support seat.

[0011] Preferably, a fixing bolt is threadedly sleeved on the front outer wall of the fixing sleeve, and a limiting circular groove matching the fixing bolt is opened on the outer wall of the lifting rod.

[0012] Preferably, a support plate is provided on the top of the lifting rod, and a soft pad is provided on the side wall of the support plate.

[0013] Preferably, a threaded rod is threadedly sleeved on the front outer wall of the support seat, and a pressure rod is connected to the end of the threaded rod.

[0014] Preferably, a cavity is provided inside the support seat, a guide groove is provided on the inner wall of the cavity, a spring is provided at the bottom of the cavity, and a pressure block is provided at the top of the spring.

[0015] Preferably, a second soft pad is provided on the top of the mounting plate, and a sliding block is provided on the bottom of the mounting plate.

[0016] Preferably, guide blocks matching the guide grooves are provided on the outer walls on both sides of the sliding block, and a limiting groove matching the pressing block is provided on the bottom of the sliding block.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are as follows: first, when it is necessary to install the rear seat, the mounting plate carrying the sliding block can be guided and slidably connected to the inside of the support seat. When the sliding block is connected to the limit position, the threaded rod can be rotated. At this time, the pressure rod at the end of the threaded rod can be rotated to press the pressure block, thereby driving the pressure block to rise and be clamped in the limit slot for limiting. When it is necessary to disassemble, the threaded rod is rotated in the opposite direction to reset the pressure rod at its end. At this time, the pressure block will be reset by the action of the spring and disengage from the limit slot, thereby making it more convenient to disassemble the rear seat. The same operation is performed when installing the storage basket. The bottom of the storage basket is provided with a mounting plate of the same structure, which is convenient for quick disengagement or installation.

[0019] During use, the support plate and the soft pad can be used to support the rider's waist, thereby improving the comfort of the person. When adjustment is needed, just loosen the fixing bolt. At this time, the fixing bolt will be away from the limiting groove, and the height of the lifting rod can be adjusted more conveniently. After the adjustment is completed, re-lock the fixing bolt for limiting, thereby supporting the waist of people of various body shapes, and its limiting effect is more stable, which can reduce the cumbersome fixing and slippage caused by traditional clamp limiting, and it is also more convenient to disassemble, and can be taken out directly after loosening the fixing bolt. The overall installation and disassembly are more convenient, which improves the practicality of the bicycle. BRIEF DESCRIPTION OF THE DRAWINGS
