The side is also provided with a detachable assembly that can be coupled to the respective fences 4 of the corresponding position, and a plurality of first elasticity disposed in the width direction of the bridge 3 is provided in the end surface of the bridge 3 in contact with the end surface of the bridge 3 and vertically. Part 704, in the present embodiment, the first elastic member 704 is a first spring, and the adjustment device 7 further includes a reduction plate 705 disposed in the width direction of the bridge 3, and the first elastic member 704 is connected to one end of its connection bottom plate 703. On the reduction plate 705 of the position, the reduction plate 705 is distingurated from the upper surface of the first elastic member 704 to be arcuous.
[0040] The operation principle of the present invention is to connect the detachable assembly of the bottom plate 703 to the fence 4 on the bridge when used, in order to achieve the purpose of mounting the adjustment device 7 on the bridge in the bridge. When the vehicle is passed on the reduction plate 705 of the adjustment device 7, the vehicle will give the deceleration plate 705 a downward pressure, and the reduction plate 705 moves down under the pressure of the pressure, at which time the first elastic member 704 is compressed and given The reduction plate 705 is an upward elastic force, whereby the first elastic member 704 functions as a buffer of the deceleration plate 705, and when the vehicle is passed down from the reduction plate 705, the reduction plate 705 will The pressure is transmitted to the bridge 3 by the first elastic member 704 and the bottom plate 703, and the bridge 3 is further transmitted to the cockpit damping device 5, thereby further achieving the effect of the cocktick deceleration, therefore, the reduction plate 705 of the present scheme When the pressure is being subjected to the vehicle, the buffer can be made by the first elastic member 704, and the pressure can also be passed to the cocktail damping device 5 to increase the effect of the cushioning deceleration, so the reduction plate 705 of the present scheme is good, At the same time, since the reducing plate 705 could be buffered, the reduction plate 705 does not easily occur in a long time, thereby greatly improving the efficiency of the deceleration plate 705.
[0041] In the present embodiment, the reduction plate 705 is rotated on both sides of the longitudinal direction of the bridge 3, and the rotating plate 706 is disposed along the width direction of the bridge 3, and the rotary plate 706 is remote from the side of its connection deceleration plate 705. Used to connect to the bridge 3, and rotate both sides of the rotating plate 706 along the width direction of the bridge 3, the circular arc surface of the pulley 711 is used to connect to the bridge 3.
[0042] Thus, by rotating on both sides of the deceleration plate 705, the rotary plate 706 is connected, when the vehicle is passed from the deceleration plate 705, the reduction plate 705 moves downward down the pressure of the vehicle, at which time the deceleration plate 705 will drive the rotation of both sides. The plate 706 is rotated, and the turning plate 706 is rotated by the pulley 711 on both sides, and the turning plate 706 acts as a more smooth effect when the vehicle is more smooth, while the pulley 711 on the turning plate 706 can also reduce The friction between the small rotating plate 706 and the bridge 3.
[0043] In the present embodiment, the detachable assembly includes a jaw ring 701 fixed to the bottom plate 703, the jaw ring 701 includes a first circular arc portion and a second circular arc portion, the first circular arc portion and the second circular arc portion close to the bottom plate. One end of 703 is fixed to the bottom plate 703 of the corresponding position, and the first circular arc portion and the second circular arc portion are formed to accommodate the mounting space of the fence 4, the first circular arc portion and the second circular arc portion away from the bottom plate. The spacing of one end of 703 is larger than the width of the fence 4, and the first circular arc portion and the second circular arc portion are separated by one end of the bottom plate 703, respectively, the first threaded hole and the second threaded hole, the first circular arc portion and the second circle The arc portion is connected by one end of the bottom plate 703 by a screw 702 through the first threaded hole and the second threaded hole.
[0044] Thus, when the adjustment device 7 is required, the screw 702 is first rotated so that the screw 702 exits from the first threaded hole and the second threaded hole, and then the fence 4 from the spacing between the first circular arc portion and the second disk. Through and enter the mounting space, then screw 702 is screwed into the first threaded hole and the second threaded hole, the screw 702 prevents the fence 4 from the first circular arc portion and the second circular arc portion. The installation space exits, thereby reaching the purpose of mounting the adjustment device 7 on the bridge 3; when the adjustment device 7 is required, the screw 702 is the same, so that the screw 702 from the first threaded hole and the first The two threaded holes are exited, and then the fence 4 is exited from the spacing between the first circular arc portion and the second circular plate, and the purpose of removing the adjustment device 7 from the bridge 3 is completed.

The connection portion of the reduction plate 705 has a vertical spacing between the corresponding positions of the arc portion.
[0048] Thus, by setting the limit lever 710, since the deceleration plate 705 is vertically slid through the connecting portion of the degradation plate 705, and the upper end of the limit lever 710 and the arcuate portion of the reduction plate 705 have a vertical spacing, when deceleration When the plate 705 moves downward to the appropriate position downward, the upper end of the limit rod 710 will be in the upper end of the reduction plate 705, and the limit bit rod 710 will support the reduction plate 705 and prevent the decelerator. The 705 continues to move down, and the limit rod 710 acts as limiting the first spring elastic force, and also achieves the purpose of decelerating the vehicle in order to prevent bumps.
[0049] In the end surface of the bottom plate 703, the bottom plate 703 is used to contact the bridge 3, and the non-slip groove 712 is uniformly distributed on the bottom plate 703 along the width direction of the bridge 3.
[0050] Thus, by providing a slip groove 712, the anti-skid groove 712 serves as an effect of increasing the friction between the bridge 3 and the bottom plate 703.
[0051] Append Figure 6 Accompany Figure 8As shown in the present embodiment, the cockstakery reducing mechanism further includes a slowdation device 8, and the mitigation device 8 includes a pallet 804, and the pallet 804 is used to secure the base 2 of the bridge, and thread is also threaded on the pallet 804.
