Detailed ways

First of all, please refer to shown in Fig. 1, the utility model is made of a chassis 10, an instrument 20 and a running platform 30; wherein, as shown in Fig. There are two guide grooves 12, and a support 14 is pivotally arranged on the two vertical rods 11 in addition. Part (such as: chassis main body or upright bar 11) and support 14 are provided with shock absorber 15, and the shock absorber of present embodiment is made of rubber block; Certainly, the equivalent element of other tool damping effect also can. The front end of the running platform 30 is provided with two guides 31 corresponding to the two guide grooves 12 of the chassis 10, and the guides 31 can be rollers or sliders. The front end of the running platform 30 is extended with an installation rod 32, the installation rod 32 is pivoted with a screw sleeve 33, and the bottom end of the corresponding screw rod 34 is pivoted on the bracket 14, and a motor 35 is provided to the screw rod 34. the power needed.

Further, the front end 301 of the running platform 30 can be controlled by the stop mechanism A provided on the chassis 10 to be in a non-floating state.

In order to allow the power to be transmitted in a balanced and stable manner, the installation rod 32 , the screw sleeve 33 and the screw rod 34 are arranged in pairs, and the two screw rods 34 are synchronously driven by a pulley set 36 . Furthermore, one of the implementations of the stopping mechanism A is to set a positioning hole 13 and a positioning pin 16 at the bottom of the guide groove 12, and the guide 31 is correspondingly provided with an insertion hole 311, and the positioning pin 16 can be inserted into the opening of the guide 31. jack 311, and control the front end 301 of the running platform 30 to be non-floating but rotatable; or a hook 101 can be set at the front end of the chassis 10 to directly hook the axial body 302 of the running platform front end 301 to make it It is in a non-floatable but rotatable state. However, the stopping mechanism A can be implemented in many ways, which will not be repeated here, and the positioning pin 16 or hook 101 of the stopping mechanism can be manually controlled, or electronic components such as solenoid valves can be used to set it into a state that can be electrically controlled.

Based on the above structure, the front end 301 of the running platform 30 is installed on the vertical rod 11 of the chassis 10 in a floating state. When the running platform 30 bears the weight W of the user, its rear end is subjected to the reaction force of the floor, so that it will not The height is changed; and the front end 301 of the running platform 30 is pressed down along the guide groove 12 of the underframe 10 by the guide 31, and the downward pressure passes through the installation rod 32, the screw sleeve 33 and the screw rod 34, and the The ㄩ-shaped support 14 is pressed forward, but the ㄩ-shaped support 14 will be resisted or pulled by the shock absorber 15 (depending on its installation position) in the process of pressing forward; The platform 30 has the effect of shock absorption, and the experimental results show that this shock absorption method has an excellent buffering effect.

As shown in Figures 4 and 5, the power of the motor 35 makes the screw 34 rotate, and the rotation of the screw 34 can make the screw sleeve 33 rise and fall, and the lifting of the screw sleeve 33 passes through the installation rod 32 to link the front end of the running platform 30 301 lifts to adjust the inclination angle of the running platform 30.

Also as shown in Figure 6, the front end 301 of the running platform 30 is first lowered to the bottom of the guide groove 12, and the front end 301 of the running platform 30 is locked by the positioning hole 13 and the positioning pin 16 of the stop mechanism (non-floating state) , and then drive the screw sleeve 33 to rise by the motor 35 and the screw rod 34, and the rising screw sleeve 33 passes through the installation rod 32 to gradually turn the running platform 30 upwards to achieve the folding effect. Therefore, the utility model has the functions of integrating shock absorption, inclination adjustment and folding structure into one.
