[0002] In the field of bicycles, the seat harness is a key component that connects the bicycle seat tube and the frame. Its stability and convenience are crucial to the riding experience. The traditional bicycle seat harness locking structure is often fixed with fasteners such as bolts and nuts. Although the structure is stable, tools are required during the disassembly and assembly process, and the operation is cumbersome and time-consuming. Especially when the seat tube needs to be quickly adjusted or replaced during riding, the shortcomings of the traditional structure are particularly obvious. In addition, although some existing quick-release structures have improved the disassembly and assembly speed, they are insufficient in locking strength and stability, and are prone to loosening during riding, affecting riding safety and comfort.

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] See also Figure 1-2 The present invention provides an embodiment: a novel bicycle seat harness quick-release locking structure, comprising a U-shaped quick-release handle 1, a C-shaped seat harness 2, a shifting rotating block 3, a fixed rotating block 4, a fixing pin 5, a plane gasket 6, a female locking screw 7 and a male locking screw 8; the C-shaped seat harness 2 is arranged on the inner side of the U-shaped quick-release handle 1, the shifting rotating block 3 is arranged on the inner side of the C-shaped seat harness 2, the fixed rotating block 4 is arranged on the inner side of the shifting rotating block 3, the fixing pin 5 is arranged on the inner side of the shifting rotating block 3, the female locking screw 7 is arranged on the inner side of the U-shaped quick-release handle 1, the male locking screw 8 is arranged on the inner side of the U-shaped quick-release handle 1, and the outer side of the female locking screw 7 is arranged with a plane gasket 6.

[0029] See also Figure 3-Figure 6In this embodiment, the U-shaped quick-release handle 1 is a U-shaped structure, which is used to manually control the locking and releasing states. Two groups of shift rotating blocks 3 are provided, and the two groups of shift rotating blocks 3 are respectively connected to the U-shaped quick-release handle 1 and the fixed rotating block 4. When in use, the two groups of shift rotating blocks 3 are rotated to realize the transmission of locking and releasing actions. When lifting, the fixed rotating block 4 is driven by the shift rotating block 3 to rotate relative to the C-shaped seat 2, thereby releasing the seat; when pressing down, the seat is locked by the same mechanism. Four groups of fixing pins 5 are provided, and the four groups of fixing pins 5 are divided into The two sets of shift rotating blocks 3 and the two sets of fixed rotating blocks 4 are respectively passed through by four sets of fixing pins 5, so that the shift rotating blocks 3 and the fixed rotating blocks 4 are firmly connected together to ensure the stability and durability of the structure. Two sets of planar gaskets 6 are provided, and the two sets of planar gaskets 6 are respectively arranged between the locking screws and the C-type seat 2. When in use, the pressure between the locking screws and the C-type seat 2 is dispersed by the two sets of planar gaskets 6 to prevent the screws from directly wearing the structural parts and improve the service life.

[0030] The male locking screw 8 and the female locking screw 7 are threadedly connected to form a locking screw structure. The locking screw structure composed of the male locking screw 8 and the female locking screw 7 penetrates the U-shaped quick-release handle 1, the shift rotating block 3, the fixed rotating block 4 and the C-shaped seat 2. When in use, the U-shaped quick-release handle 1, the shift rotating block 3, the fixed rotating block 4 and the C-shaped seat 2 are tightly locked through the threaded connection between the male locking screw 8 and the female locking screw 7 to achieve a locking function. The C-shaped seat 2 is an embracing structure. The C-shaped seat 2 fits tightly to the outer surface of the bicycle seat tube. When in use, The seat tube is effectively clamped and fixed by the rotational cooperation of the fixed rotating block 4 and the shift rotating block 3. The shift rotating block 3 is hinged to the fixed rotating block 4 by the fixed pin 5. The shift rotating block 3 can rotate within a certain range relative to the fixed rotating block 4. When in use, the C-type seat harness 2 can be locked and loosened by rotating the shift rotating block 3 within a certain range relative to the fixed rotating block 4. The thread directions of the locking screw female nail 7 and the locking screw male nail 8 are opposite. When the locking screw is rotated, an inward clamping force can be generated at the same time to ensure the locking effect of the structure.

[0031] When working, first assemble the various components; fit the C-type seat 2 tightly to the outer surface of the bicycle seat tube to ensure that the embracing design can completely wrap the seat tube; then, hinge the two groups of shifting rotating blocks 3 with the fixed rotating blocks 4 through the fixing pins 5 respectively to ensure that the shifting rotating blocks 3 can rotate freely within a certain range relative to the fixed rotating blocks 4; then, install the assembled shifting rotating blocks 3 and the fixed rotating blocks 4 to the inner side of the C-type seat 2 to ensure that the positions of the various components are correct and the connection is firm; finally, connect the U-type quick-release handle 1 to the shifting rotating block 3, and install the locking screw female nail 7 and the locking screw male nail 8 to the inner side of the U-type quick-release handle 1 respectively, and place two groups of flat gaskets 6 between the locking screws and the C-type seat 2 to disperse the pressure and protect the structural parts;

[0032] After the assembly is completed, the locking operation is performed; first, the U-shaped quick-release handle 1 is pressed down, and the fixed rotating block 4 is driven to rotate relative to the C-shaped seat assembly 2 by the shift rotating block 3, so that the C-shaped seat assembly 2 clamps the seat tube more tightly; then, the male locking screw 8 and the female locking screw 7 are rotated. Since the thread directions of the two are opposite, an inward clamping force can be generated at the same time during rotation, so that the U-shaped quick-release handle 1, the shift rotating block 3, the fixed rotating block 4 and the C-shaped seat assembly 2 are tightly locked; at this time, the flat gasket 6 will effectively disperse the pressure between the locking screw and the C-shaped seat assembly 2, prevent the screw from directly wearing the structural parts, and ensure the stability and safety of the locking effect;

[0033] When it is necessary to disassemble the bicycle seat, the disassembly operation is performed; first, the male locking screw 8 and the female locking screw 7 are rotated in the opposite direction to loosen the locking screw structure; then, the U-shaped quick-release handle 1 is lifted up, and the fixed rotating block 4 is driven by the shifting rotating block 3 to rotate in the opposite direction relative to the C-shaped seat 2, so that the C-shaped seat 2 gradually loosens the clamping of the seat tube; finally, each component is disassembled in turn to complete the entire disassembly process; since the present invention adopts a quick-release locking structure, the user only needs to complete the disassembly and assembly of the seat through simple manual operation, which greatly improves the convenience and efficiency of the operation.

[0034] Through the above steps, the shifting rotating block is connected to the fixed rotating block 4 by the fixing pin 5, the fixed rotating block 4 is connected to the C-type seat 2, the shifting rotating block is connected to the U-type quick release handle 1, and the locking screws are used to connect. The seat can be quickly loosened by lifting the U-type quick release handle 1, and the seat can be quickly locked by pressing the U-type quick release handle 1.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
