Description

Lifting and adjusting device for bicycle seat cushion

technical field

The utility model relates to a lifting adjustment device for a bicycle seat cushion.

Background technique

At present, the connection structure is made with a connecting rod between the bicycle seat cushion and the vehicle frame. The known seat cushion and the connecting rod are locked into one body, and the connecting rod is then connected to the car frame, and the connecting rod is connected to the car frame to adjust the required telescopic length in conjunction with the height of the cyclist or the length of the foot. However, this adjustment structure is only a structure in which the circular tube is stretched and then locked. The rider cannot adjust the height of the seat cushion at any time during the journey, which cannot meet the needs of safety, convenience and comfort.

Utility model content

The purpose of the utility model is to provide a lifting adjustment device for a bicycle seat cushion, so that the rider can have a more convenient lifting and lowering of the seat cushion, and achieve the goal of safety and comfort.

The purpose of this utility model is to realize through the following technical solutions:

The utility model relates to a lifting adjustment device for a bicycle seat cushion, which comprises a device main body, a generally used bicycle seat cushion is sleeved on the top of the device main body, and a general bicycle frame is connected to the bottom of the device main body. There is a telescopic rod on the top of the device body, a piston rod is installed inside the telescopic rod, a valve rod is interspersed inside the piston rod, the bottom of the piston rod is connected to the piston, and the cavity formed between the piston, the device body and the piston rod is filled with oil. , The bottom of the piston is provided with a baffle, the piston and the baffle are provided with a spring, and the valve at the bottom of the baffle and the valve rod rests against a spring. The lifting adjustment device mainly uses the principle of oil pressure to control the telescopic length of the piston rod. The shaft rod is extended to make the telescopic rod push up the seat cushion, otherwise the piston rod can be shortened to lower the seat cushion; in order to prevent the rotation between the device and the seat cushion, the outer edge of the telescopic rod is set correspondingly to the inner edge of the upper end of the device body. With anti-rotation structure, the button device on the bicycle handle pulls the pull wire to control the movement of the valve rod. The valve rod passes through the center of the piston rod and can move up and down to control the opening and closing of the valve; or the button device pulls the pull wire to rotate the valve The lever controls the relative position between the valve and the oil hole, and forms the state of the oil passage being open or blocked; there is an assembly cover under the device body, a spring is provided between the cover and the partition, and a spring is formed between the partition, the cover and the device main body. The cavity is filled with oil.

Another opportunity to operate the seat cushion lifting, as all bicycle riders know, is that when the vehicle is parked or the speed is slow, the low-height seat cushion feet can easily touch the ground, so as to keep the body balanced and achieve a safe effect. When driving, the seat cushion is low, and the feet will be bent, which is not conducive to pedaling force. Therefore, the seat cushion can be raised to achieve the best state of pedaling force. The creator created this new creation to solve this problem. When the cyclist wants to raise the seat cushion while driving, he only needs to activate the button on the handlebar, and at the same time step on the pedal with both feet to let the buttocks leave the seat cushion. This device can Elongated via internal spring force, the seat cushion is raised, allowing the rider to stretch their feet more comfortably on the pedals.

The beneficial effects of the utility model are: using the oil pressure principle to control the lifting of the seat cushion, the lifting of the seat cushion can be controlled by the rider at the handlebar of the bicycle; when the control is started at the handlebar, the seat cushion is lowered by the weight of the rider; When there is no load on the cushion, the seat cushion can be raised by the internal spring force of this device; when the control is not activated, the lift is adjusted to a locked state. The height of the seat cushion is adjusted according to the safety and comfort of the cyclist. For example, when the bicycle is stopped or the speed is slow, the cyclist lowers the seat cushion of the bicycle so that the feet can be supported on the ground at any time to protect the safety of the body. During the journey, the height of the seat cushion is raised due to the needs of human mechanics, so that the rider's legs can be stretched, so that he can ride comfortably with strength. In order to achieve the purpose of safe, convenient and comfortable riding.
