Description

Technical Field

[0001] This utility model relates to the field of bicycle dropper seat technology, and in particular to a foldable seat height adjustment handle. Background Technology

[0002] As we all know, a bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power it by pedaling, making it a green and environmentally friendly mode of transportation. The seatpost, located in the middle of the bicycle, is a component used to connect to the seat and is usually secured with a locking ring.

[0003] Currently, with the development of technology, bicycle seatposts have evolved into pneumatic dropper systems. These seatposts typically feature a seat height adjustment handle for height adjustment. The seat height is controlled by swinging the handle and pressing the adjustment button. However, existing seat height adjustment handles are all single units. For example, the hand-operated adjustment structure of the bicycle dropper seatpost disclosed in patent number 202420254797.7 is quite long to accommodate the user's external grip, thus taking up considerable space during packaging and transportation, which is inconvenient. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a foldable seat height adjustment handle that can reduce packaging space.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable seat height adjustment handle includes a height adjustment seat tube and a handle. The handle includes a front rod and a rear rod. A hinge seat is formed at the lower end of the outer end face of the front rod and the lower end of the inner end face of the rear rod. A magnet is provided at the upper end of the outer end face of the front rod and the upper end of the inner end face of the rear rod. The front rod and the rear rod are hinged together by the hinge seat. A pressing head is formed on the inner end face of the front rod, and the upper end of the middle part of the front rod is hinged to the base of the height adjustment seat tube, so that the pressing head is placed at the adjustment button of the height adjustment seat tube.

[0007] Preferably, a torsion spring is installed at the hinge seat, and under the action of the torsion spring, the front rod and the rear rod always tend to fit together.

[0008] Preferably, the shaft of the rear rod gradually bends downwards.

[0009] Preferably, a protrusion is provided at the end of the rear rod, and the diameter of the protrusion is larger than the diameter of the rear rod body.

[0010] Preferably, the pressure head is shaped like an eagle's beak, and the lower end face of the pressure head abuts against the top of the adjustment button of the lifting seat tube.

[0011] By adopting the above solution, this utility model divides the handle into two sections, a front rod and a rear rod, which can rotate along the hinge seat. The rear rod, which is used by the user for gripping, can be folded. Therefore, during packaging, the rear rod and the front rod can be folded together, thereby shortening the packaging length of the handle, reducing the required storage space, facilitating transportation, and reducing transportation costs.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection.

[0018] like Figures 1 to 3 As shown, this embodiment provides a foldable seat height adjustment handle, including a height adjustment seat tube 1 and a handle 2. The handle 2 includes a front rod 21 and a rear rod 22. A hinge seat 23 is formed at the lower end of the outer end face of the front rod 21 and the lower end of the inner end face of the rear rod 22. A magnet 24 is provided at the upper end of the outer end face of the front rod 21 and the upper end of the inner end face of the rear rod 22. The front rod 21 and the rear rod 22 are hinged together by the hinge seat 23. A pressing head 25 is formed on the inner end face of the front rod 21, and the upper end of the middle part of the front rod 21 is hinged to the base 11 of the height adjustment seat tube 1, so that the pressing head 25 is placed at the adjustment button 12 of the height adjustment seat tube 1.

[0019] In this embodiment, the handle 2 is divided into two sections, a front rod 21 and a rear rod 22, which can rotate along the hinge seat 23. The rear rod 22, which is used by the user for gripping, can be folded. Therefore, when packaging, the rear rod 22 and the front rod 21 can be folded together, thereby shortening the packaging length of the handle 2, reducing the required storage space, facilitating transportation, and reducing transportation costs.

[0020] In actual use, the presence of magnet 24 will hold the front rod 21 and the rear rod 22 together, keeping them in a complete handle state. Since the hinge seat 23 is located below and the magnet is located above, the direction of touching the adjustment button 12 is to pull the handle upward, so the front rod 21 and the rear rod 22 will not break apart when adjusting the lifting seat tube 1.

[0021] Furthermore, vibrations are inevitable during operation. Since the front rod 21 and rear rod 22 are only held together by magnet 24, it's difficult to maintain their engagement solely through magnet 24. Therefore, a torsion spring 26 is installed at the hinge seat 23 in this embodiment. Under the action of the torsion spring 26, the front rod 21 and rear rod 22 always tend to be in contact with each other, thus maintaining a consistent state unless the rear rod 22 is folded manually. Alternatively, when folding for packaging and transportation is required, it can be folded directly and then stored within the inner liner box frame, with the unfolding mechanism providing support.

[0022] Furthermore, to facilitate customer gripping, the rear bar 22 in this embodiment gradually bends downward to form a gripping part that can be gripped by the user.

[0023] Furthermore, to prevent hand slippage during gripping, a protrusion 27 is provided at the end of the rear rod 22 in this embodiment. The diameter of the protrusion 27 is larger than the diameter of the rear rod 22, thereby providing a force-bearing point at the rear.

[0024] Furthermore, in order to better ensure that the pressure head 25 can simultaneously press the adjustment button 12 when the handle is turned upward, the pressure head 25 in this embodiment is shaped like an eagle's beak, and the lower end face of the pressure head 25 touches the top of the adjustment button 12 of the lifting seat tube 1.

[0025] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
