Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically to a quick-release locking device for bicycle seat bundles. Background Technology

[0002] Currently, bicycles typically have an inner saddle tube inserted into the frame's outer tube to allow for seat height adjustment to suit different rider heights. A locking device is located at the end of the outer tube, allowing for selective tightening and loosening of the inner saddle tube for easy adjustment as needed. Traditional bicycle locking devices primarily use bolts and nuts for fastening. While structurally stable, these require tools like screwdrivers for assembly and disassembly, making the process cumbersome and time-consuming. This fails to meet the rider's need for quick seat height adjustments or saddle replacements during riding. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 5As shown, the bicycle seat cluster quick-release locking device of this embodiment includes a seat cluster 1, a quick-release wrench 2, and a pivot 3. The quick-release wrench 2 is rotatably connected to the seat cluster 1 via the pivot 3. The seat cluster 1 has a first opening 100, and a first lug 101 and a second lug 102 are respectively formed on both sides of the first opening 100. The quick-release wrench 2 has a second opening 200, and a first axle seat 201 and a second axle seat 202 are respectively formed on both sides of the second opening 200. A first fixing and tightening plate 4 is provided between the first axle seat 201 and the first lug 101, and a second fixing plate 4 is provided between the second axle seat 202 and the second lug 102. The first fixed clamping plate 5 is provided with a first spiral pushing slope 6 on the side of the first fixed clamping plate 4 near the first shaft seat 201 and on the side of the second fixed clamping plate 5 near the second shaft seat 202. The second spiral pushing slope 7 is provided on the side of the first fixed clamping plate 4 near the first shaft seat 201 and on the side of the second fixed clamping plate 5 near the second shaft seat 202. The quick-release wrench 2 can be rotated so that the highest point of the first spiral pushing slope 6 overlaps with the highest point of the second spiral pushing slope 7, or the highest point of the first spiral pushing slope 6 overlaps with the lowest point of the second spiral pushing slope 7. The bicycle seat cluster quick-release locking device includes a seat cluster 1, a quick-release wrench 2, a pivot 3, a first fixing plate 4, and a second fixing plate 5. The seat cluster 1 has a first lug 101 and a second lug 102. The quick-release wrench 2 has a first axle seat 201 and a second axle seat 202. The first fixing plate 4 is located between the first axle seat 201 and the first lug 101. The second fixing plate 5 is located between the second axle seat 202 and the second lug 102. The pivot 3 passes through the seat cluster 1, the quick-release wrench 2, the first fixing plate 4, and the second fixing plate 5, allowing the quick-release wrench 2 to be rotatably connected to the seat cluster 1. The first axle seat 2... The first spiral pushing inclined surface 6 is provided on the first and second axle seats 202 respectively, and the second spiral pushing inclined surface 7 is provided on the first and second fixed clamping plates 4 and 5 respectively. By rotating the quick-release wrench 2, when the highest point of the first spiral pushing inclined surface 6 overlaps with the highest point of the second spiral pushing inclined surface 7, the seat bundle 1 is in a locked state. When the highest point of the first spiral pushing inclined surface 6 overlaps with the lowest point of the second spiral pushing inclined surface 7, the seat bundle 1 is in a loosened state. It has the advantages of simple structure, few components, conforming to the trend and requirements of lightweight design of bicycle parts, convenient and quick locking and unlocking operation, and good ease of use.

[0021] Preferably, the first spiral jacking inclined surface 6 has two discontinuous spiral inclined surfaces, each covering 180°; the second spiral jacking inclined surface 7 also has two discontinuous spiral inclined surfaces, each covering 180°. In this embodiment, both the first spiral jacking inclined surface 6 and the second spiral jacking inclined surface 7 have two discontinuous spiral inclined surfaces, each covering 180°. Symmetrical force distribution reduces unilateral wear. During the rotation process from the highest point of the first spiral jacking inclined surface 6 to the lowest point of the second spiral jacking inclined surface 7, the rotational motion is converted into axial thrust, causing the diameter of the seat bundle 1 to tighten, achieving self-locking. The reverse action enables quick disassembly and release.

[0022] Preferably, the first lug 101 and the first fixed clamping plate 4, and the second lug 102 and the second fixed clamping plate 5 are circumferentially fixedly connected by a circumferential fixed connection structure 8. In this embodiment, the first fixed clamping plate 4 and the first lug 101 are circumferentially fixedly connected, and the second fixed clamping plate 5 and the second lug 102 are circumferentially fixedly connected, so that when the quick-release wrench 2 is turned, the first spiral pushing inclined surface 6 on the first shaft seat 201 and the second shaft seat 202 can rotate relative to the second spiral pushing inclined surface 7 on the first fixed clamping plate 4 and the second fixed clamping plate 5. This allows the highest point of the first spiral pushing inclined surface 6 to move from the highest point of the second spiral pushing inclined surface 7 to the lowest point of the second spiral pushing inclined surface 7 as the quick-release wrench 2 rotates. At this time, the bicycle seat quick-release locking device of this invention is in a loose state, or it moves from the lowest point of the second spiral pushing inclined surface 7 to the highest point of the second spiral pushing inclined surface 7. At this time, the bicycle seat quick-release locking device of this invention is in a locked state.

[0023] Preferably, the circumferential fixed connection structure 8 includes a positioning groove 801 provided on the first lug 101 and the second lug 102, and a positioning protrusion 802 provided on the first fixed clamping plate 4 and the second fixed clamping plate 5, wherein the positioning protrusion 802 is fitted and connected to the positioning groove 801. In this embodiment, the first lug 101 is provided with a positioning groove 801, and the first fixing and tightening plate 4 is provided with a positioning protrusion 802. The positioning protrusion 802 on the first fixing and tightening plate 4 is fitted and connected with the positioning groove 801 on the first lug 101, so that the first fixing and tightening plate 4 is circumferentially fixedly connected with the first lug 101. Similarly, the second lug 102 is provided with a positioning groove 801, and the second fixing and tightening plate 5 is provided with a positioning protrusion 802. The positioning protrusion 802 on the second fixing and tightening plate 5 is fitted and connected with the positioning groove 801 on the second lug 102, so that the second fixing and tightening plate 5 is circumferentially fixedly connected with the second lug 102. In other embodiments, the circumferential fixed connection structure 8 can also be provided with pin holes on the first lug 101 and the second lug 102, and with cylindrical pins on the first fixing and tightening plate 4 and the second fixing and tightening plate 5. The circumferential fixed connection is achieved by interference fit between the cylindrical pin and the pin hole, which is not limited to this embodiment.

[0024] Preferably, a first limiting protrusion 203 and a second limiting protrusion 204 are respectively formed on the opposite inner sides of the quick-release wrench 2 near the second opening 200. In this embodiment, by providing the first limiting protrusion 203 and the second limiting protrusion 204 on the quick-release wrench 2, when the quick-release wrench 2 is pulled down to the locking position (e.g. Figure 5 As shown), the first limiting protrusion 203 and the second limiting protrusion 204 will abut against the outer tube of the frame 300 to prevent the quick-release wrench 2 from rotating excessively, causing the highest point of the first spiral pushing slope 6 to cross the highest point of the second spiral pushing slope 7, resulting in the failure of the locking function of the seat harness 1.

[0025] Preferably, the inner side of the seat belt 1 is formed with an abutment protrusion 103, the top surface of which is flush with the upper end surface of the seat belt 1. In this embodiment, when the seat belt 1 is inserted into the outer tube of the frame 300, the abutment protrusion 103 abuts against the upper end surface of the outer tube of the frame 300 to play a positioning role, so that the seat belt 1 is positioned at the upper end of the outer tube of the frame 300, thereby allowing the seat belt 1 to compress the outer tube of the frame 300 and tighten the inner tube of the seat cushion 400, achieving the effect of adjusting the height of the seat cushion.

[0026] Preferably, a fastening screw 9 is provided on the seat harness 1. In this embodiment, when the seat harness 1 is inserted into the outer tube of the frame 300, the fastening screw 9 can be inserted between the seat harness 1 and the outer tube of the frame 300, which effectively improves the connection stability between the seat harness 1 and the outer tube of the frame 300 and prevents the seat harness 1 from coming off the outer tube of the frame 300.

[0027] Preferably, the pivot 3 includes a male locking screw 301 and a female locking screw 302, with the male locking screw 301 and the female locking screw 302 threadedly connected. In this embodiment, the female locking screw 302 passes sequentially from one side of the second bearing seat 202 through the second bearing seat 202, the second fixing plate 5, the second lug 102, the first lug 101, the first fixing plate 4, and the first bearing seat 201. The male locking screw 301 enters the female locking screw 302 from one side of the first bearing seat 201 and is threadedly connected, thereby tightly locking the bearing seat 1, the quick-release wrench 2, the first fixing plate 4, and the second fixing plate 5, making disassembly and assembly convenient and quick.

[0028] The above description is merely a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the technical concept of this utility model should also be considered within the protection scope of this utility model.
