Convenient pedal structure

Abstract

The invention discloses a convenient pedal structure, relates to the technical field of trailer structures and aims at solving the technical problem that an existing pedal structure is not labor-saving. The key point of the technical scheme is that a rotating disc is rotationally connected to the top wall of an underframe; an inserting rod is slidingly connected to the side wall of the underframe;an inserting hole for the top end of the inserting rod to insert is formed in the bottom wall of the rotating disc; an elastic piece used for pushing the inserting rod into the inserting hole is fixedly arranged on the side wall of the underframe; a foot bar is rotationally connected to the bottom end of the inserting rod; supporting blocks are correspondingly and fixedly arranged in the positions, positioned on the two sides of the inserting rod, on the side wall of the underframe; the two supporting blocks both abut against the top wall of the foot bar; when the inserting rod needs to be pulled away from the inserting hole, the foot steps on one pedal to drive the foot bar to rotate, one end, close to the foot, of the foot bar moves down, one end, far away from the foot, of the foot barabuts against the supporting block, and therefore, the inserting rod can be driven to move down through the middle part of the foot bar so as to pull the inserting rod away from the inserting hole tofacilitate rotating the rotating disc in the following; and due to the use of a lever principle, the convenient pedal structure is more labor-saving in operation and more convenient when being compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of trailer structure, more specifically, it relates to a convenient pedal structure. Background technique [0002] The pedal structure is a mechanical structure used to control the connection relationship between the chassis of the trailer and the turntable. [0003] A pedal structure reference in the prior art Figure 7 and Figure 8 As shown, it includes an underframe 1, the top wall of the underframe 1 is rotatably connected with a turntable 11, the side wall of the underframe 1 is rotatably connected with a joystick 5, the outer sidewalls at both ends of the joystick 5 are fixed with pedals 31, and the middle part of the joystick 5 The outer side wall of the bottom frame 1 is fixed with a pressure plate 51, the side wall of the bottom frame 1 is slidably connected with the insertion rod 13, the side wall of the insertion rod 13 is fixed with an extension plate 52, the pressure plate 51 abuts against the...

[0004] However, it drives the plunger 13 downward by overcoming the elastic force of the elastic member 4 through the rotation of the pressing plate 51, and the arm of force is shorter, that is, the labor intensity is higher, and it is not labor-saving, so it needs to be improved.
