Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Referring to Fig. 1～Figure 16, the utility model embodiment comprises front support stand 1, rear support stand 2, button assembly 3, connecting rod 4, support rail 5, pedal 6.
The upper articulation of the top of front support stand 1 and rear support stand 2.
Support rail 5 is fixed on rear support stand 2.
Pedal 6 one end and front support stand 1 are hinged.One end of connecting rod 4 and pedal 6 are hinged, and the other end and rear support stand 2 are hinged.
Button assembly 3 comprises button 7, elastic component 8, rotor 9, upper buckle 10, sleeve pipe 11, lower buckle 12.
Rotor 9 is rotatably connected on pedal 6.
Button 7 is fixing with rotor 9, and in the present embodiment, button 7 is one-body molded with rotor 9.
Elastic component 8 one end are connected with pedal 6, and the other end is connected with rotor 9.
Upper buckle 10 is fixing with rotor 9, and in the present embodiment, upper buckle 10 is one-body molded with rotor 9.On upper buckle 10, be provided with wedge surface 13.
Sleeve pipe 11 is fixed on support rail 5.
Lower buckle 12 is fixing with sleeve pipe 11, and in the present embodiment, lower buckle 12 is one-body molded with sleeve pipe 11.Lower buckle 12 can be connected by disengaged with upper buckle 10.On lower buckle 12, be provided with lower wedge surface 14.
Be provided with groove 15 at described pedal 6 front ends, button 7 is actively plugged in groove 15, and groove 15 plays a protective role to button 7, makes staff can arbitrarily not encounter button 7 and causes potential safety hazard, and making the utility model overall structure more compact.
On button 7 or rotor 9, be fixed with and turned spacer pin 16, cross and turn spacer pin 16 and coordinate with pedal 6, when button 7 or rotor 9 rotate when excessive, cross and turn spacer pin 16 and contact with pedal 6, pedal 6 blocked and turned spacer pin 16, and button 7 and rotor 9 are no longer rotated further.
In the time that the utility model launches gradually, connecting rod 4 is linked by rear support stand 2, drives pedal 6 to turn over downwards, while arriving certain position, upper wedge surface 13 contacts with lower wedge surface 14, produces extruding when upper wedge surface 13 contacts with lower wedge surface 14, makes lower buckle 12 and the easier clamping of upper buckle 10; When the utility model launches completely (the utility model is in use state), pedal 6 basic horizontal, pedal 6 rides on support rail 5, under the elastic force effect of elastic component 8, lower buckle 12 and upper buckle 10 clampings, make the utility model be in use state, and people may stand on pedal 6.
In the time that the utility model draws in, connecting rod 4 is linked by rear support stand 2, drives pedal 6 upwards to turn over, and presses button 7, and button 7 drives rotor 9 to rotate, and rotor 9 drives upper buckle 10 to rotate, and lower buckle 12 departs from upper buckle 10.Release button 7, under the elastic force effect of elastic component 8, upper buckle 10 resets.
