The utility model discloses a double stroke foot -operated opening device, including double stroke foot -operated opening mechanism and multilink lever drive mechanism, the bottom of the barrel body is integrally formed with the bucket bottom of recess, and double stroke foot -operated opening mechanism includes pedal, pedal connecting rod, pedal support and return spring, and the pedal is fixedly connected with pedal connecting rod, and the pedal is hinged on the pedal support, and the pedal support is fixed in the inner wall of the recess of the bucket bottom, and the pedal connecting rod swings up and down around the pedal support, and the return spring is connected with the pedal connecting rod and is used for providing restoring force, and multilink lever drive mechanism includes scissor mechanism, drive connecting rod, connecting pair, pull rod. By improving the traditional whole top cover into two section structure, and combining double stroke foot -operated opening mechanism and multilink lever drive mechanism, realize the operation mode of " half -step open front cover, full -step full open", and the structure significantly reduces the opening force, expands the angle of the throw mouth, improves the convenience and the health of throwing.

This application provides a sunroof sealing ring and its usage method to at least solve the problem of balancing sealing performance and resistance in the prior art. A sunroof sealing ring includes a first sealing part, a first connecting part, an abutting part, a second connecting part, and a second sealing part. The second sealing part is connected to the upper and / or lower end of the abutting part via the second connecting part, and the first sealing part is connected to the upper and / or lower end of the abutting part via the second connecting part, or the first connecting part and the second connecting part are directly connected. The abutting part is located between the first and second sealing parts and can move or rotate relative to the first and second sealing parts under external force. The design of this application can reduce the force required to open the sunroof, reduce opening resistance, reduce wear, and extend service life. Furthermore, since the sunroof does not leak, a water channel structure is not needed below the sunroof, making the structure simpler and saving space, thus reducing the design cost of the sunroof.
