Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, specifically to an angle-adjustable bicycle seat support structure. Background Technology

[0002] Bicycles, also known as pedal bikes, are driven by two sets of tires that propel the main frame. Users simply sit on the seat, hold the handlebars, and pedal. The chain provides power, which in turn drives the rear wheel with a sprocket. Bicycles are environmentally friendly and convenient, making them a very common mode of transportation.

[0003] In the structure of a bicycle, the seatpost is the connecting tool that inserts the saddle and its stem. While it allows the saddle to be moved up and down along the internal cavity of the seatpost to change its height, it's difficult to adjust its angle. Furthermore, the connection between the saddle and the seatpost is too simple, making it prone to sagging during riding.

[0004] Now, a novel angle-adjustable bicycle seat support structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an angle-adjustable bicycle seat support structure to solve the problem of inconvenient seat angle adjustment mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable bicycle seat support structure, comprising a seat post body and an outer cylinder body. The front and rear ends of the surface of the seat post body are respectively fixed with the outer cylinder body, and a long slot is provided on the upper part of the inner part of the outer cylinder body. A sliding rod is movably inserted into the upper part of the long slot body. Toothed rows are respectively fixed in the inner walls on both sides of the sliding rod. Gears are movably connected to the top of both sides of the long slot body. A positioning hole is provided on the surface of the sliding rod. A support plate is movably connected between the front and rear ends of the top of the sliding rod. Two bolts are installed in the holes on the surface of the outer cylinder body.

[0007] As a further technical solution of this utility model, a vertical tube is spliced ​​below the seat tube body, and an assembly piece is welded to the bottom of the seat tube body and the top of the vertical tube respectively. The front end and the rear end of the assembly piece are respectively provided with screw holes, and a bolt is assembled between the screw holes, and a nut is sleeved on the outside of the bolt.

[0008] As a further technical solution of this utility model, the inner side of the bolt three is embedded in the positioning hole, and the gear can guide the slide rod with toothed row to slide back and forth.

[0009] As a further technical solution of this utility model, a short slot is provided below the long slot, and a plug rod is movably connected between the short slot and the long slot. A limit block is fixed at the bottom of the plug rod, a rubber ring is fixed between the short slot and the long slot, and a spring is installed between the lower part of the long slot and the slide rod.

[0010] As a further technical solution of this utility model, the insertion rod is inserted into the rubber ring, and the insertion rod and the rubber ring are arranged together in concentric circles.

[0011] As a further technical solution of this utility model, the spring is sleeved on the outside of the insertion rod, and the top of the insertion rod is fixedly connected to the slide rod.

[0012] As a further technical solution of this utility model, the front and rear ends of the bottom sides of the support plate are respectively provided with sliding grooves, the upper hinge seat is movably connected inside the sliding groove, and a thin rod is movably connected in the upper hinge seat. The top ends of both sides of the sliding rod are respectively fixed with lower hinge seats, and hollow tubes are movably connected in the lower hinge seats. Bolt four is installed in the upper hole outside the hollow tube, and bolt two is installed in the upper hole on the surface of the sliding rod.

[0013] As a further technical solution of this utility model, the bottom of the thin rod is embedded in the hollow tube, and the upper hinge seat can move left and right along the inner wall of the slide groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the adjustable bicycle seat support structure not only realizes the adjustment of the seat position and the maintenance of the seat post structure, but also prevents the seat from tilting.

[0015] (1) By fixing an outer cylinder to the front and rear ends of the main body of the seat tube, the front and rear ends of the main body of the seat tube are respectively connected to the slide rod through the outer cylinder. Under the action of the meshing gear rack on both sides, the slide rod is pulled back and forth. After aligning the positioning hole, the bolt three is screwed in for reinforcement. The support plate at the top is hinged between the two sets of slide rods. The bolt two at the front and rear ends is used to adjust the angle of the support plate. The height and angle of the seat tube and seat cushion structure are adjusted from multiple aspects to prevent the support plate and seat cushion from sliding down.

[0016] (2) By installing a spring between the lower part of the long slot and the slide bar, when people sit on the seat, the slide bar slides along the long slot and is embedded in the short slot. It will be affected by the elastic force of the spring. Through the rubber ring, it can provide reverse support force to the top slide bar. Even if it is bumpy during riding, it can automatically adjust the squeezing force to avoid damage caused by direct squeezing between the rods and protect the waist and hips.

[0017] (3) By setting sliding grooves at the front and rear ends on both sides of the bottom of the support plate, the upper hinge seat is moved left and right along the sliding grooves on both sides, and then the thin rod is pulled out from the hollow tube and fixed with bolt four. After adjusting the angle of the support plate, the support plate is reinforced from the front and rear ends on both sides to prevent the support plate from tilting or deforming during the movement and to maintain the stability of the tilt angle of the support plate.
