[0002] In the bicycle industry, the seat harness, as a key component connecting the seat tube to the bicycle frame, is crucial to the riding experience due to its stability and convenience. Traditional bicycle seat harness locking structures often use fasteners such as bolts and nuts for fastening. While structurally stable, assembly and disassembly require tools, are cumbersome, and time-consuming. The shortcomings of traditional structures are particularly evident when the seat tube needs to be quickly adjusted or replaced during riding. Furthermore, while some existing quick-release mechanisms improve assembly and disassembly speed, they lack locking strength and stability, making them prone to loosening during riding, impacting riding safety and comfort.

[0003] Therefore, in response to the above problems, a new type of bicycle seat harness quick-release locking structure is proposed, which connects the shifting rotating block and the fixed rotating block through a fixed pin, connects to the C-shaped seat harness through the fixed rotating block, connects to the U-shaped quick-release handle through the shifting rotating block, and is connected through locking screws, thereby realizing the function of quickly disassembling and locking the bicycle seat harness; the user only needs to complete the disassembly and assembly of the seat harness through simple manual operation, thereby improving the convenience and efficiency of operation.

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

[0028] See also Figure 1-2 The utility model 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 flat gasket 6, a female locking screw 7 and a male locking screw 8; the C-shaped seat harness 2 is provided on the inner side of the U-shaped quick-release handle 1, the shifting rotating block 3 is provided on the inner side of the C-shaped seat harness 2, the fixed rotating block 4 is provided on the inner side of the shifting rotating block 3, the fixing pin 5 is provided on the inner side of the shifting rotating block 3, the female locking screw 7 is provided on the inner side of the U-shaped quick-release handle 1, the male locking screw 8 is provided on the inner side of the U-shaped quick-release handle 1, and the outer side of the female locking screw 7 is provided with a flat gasket 6.

[0029] See also Figure 3-6In this embodiment, the U-shaped quick-release handle 1 is a U-shaped structure 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 rotate 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 harness 2, thereby releasing the seat harness; when pressing down, the seat harness 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 Don't pass through the two groups of shift rotating blocks 3 and the two groups of fixed rotating blocks 4. When in use, four groups of fixing pins 5 are used to pass through the two shift rotating blocks 3 and the two fixed rotating blocks 4 respectively, 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. There are two groups of flat gaskets 6, and the two groups of flat gaskets 6 are respectively arranged between the locking screws and the C-type seat harness 2. When in use, the two groups of flat gaskets 6 are used to disperse the pressure between the locking screws and the C-type seat harness 2 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 passes through the U-shaped quick-release handle 1, the shift rotating block 3, the fixed rotating block 4 and the C-shaped seat harness 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 harness 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 harness 2 is an embracing structure. The C-shaped seat harness 2 fits tightly to the outer surface of the bicycle seat tube. When in use, By the rotational cooperation of the fixed rotating block 4 and the shift rotating block 3, the seat tube is effectively clamped and fixed. The shift rotating block 3 and the fixed rotating block 4 are hinged 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-shaped seat harness 2 tightly to the outer surface of the bicycle seat tube, ensuring that the embracing design can completely wrap the seat tube; then, hinge the two sets of shifting rotating blocks 3 with the fixed rotating block 4 through the fixing pins 5, ensuring that the shifting rotating block 3 can rotate freely within a certain range relative to the fixed rotating block 4; then, install the assembled shifting rotating block 3 and the fixed rotating block 4 to the inner side of the C-shaped seat harness 2, ensuring that the positions of the various components are correct and the connection is firm; finally, connect the U-shaped quick-release handle 1 to the shifting rotating block 3, and install the female locking screw 7 and the male locking screw 8 to the inner side of the U-shaped quick-release handle 1, respectively, and place two sets of flat gaskets 6 between the locking screws and the C-shaped seat harness 2 to disperse the pressure and protect the structural parts;

[0032] After assembly is complete, 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 shifting 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 threads of the two screws are in opposite directions, they can simultaneously generate an inward clamping force during rotation, tightly locking the U-shaped quick-release handle 1, the shifting rotating block 3, the fixed rotating block 4 and the C-shaped seat assembly 2. At this time, the flat gasket 6 will effectively disperse the pressure between the locking screw and the C-shaped seat assembly 2, preventing the screws from directly abrading the structural components, and ensuring 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 opposite directions 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 to rotate in the opposite direction relative to the C-shaped seat 2 by shifting the rotating block 3, so that the C-shaped seat 2 gradually loosens its grip on the seat tube; finally, each component is disassembled in turn to complete the entire disassembly process; since the utility model 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 operation.

[0034] Through the above steps, the shifting rotation block is connected to the fixed rotating block 4 using the fixing pin 5, the fixed rotating block 4 is connected to the C-shaped seat 2, the shifting rotation block is connected to the U-shaped quick release handle 1, and the locking screws are used to connect. Lifting the U-shaped quick release handle 1 can quickly loosen the seat, and pressing down the U-shaped quick release handle 1 can quickly lock the seat.

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