Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 base, 2 depression bars, 3 pressing plates, 4 retracing springs, 5 spring blocks, 6 straight connection rods, 7 curved rods, 8 side plates, 9 control desks, 10 travel switches.
The specific embodiment
The invention will be further described below in conjunction with Figure of description:
As shown in Figure 1, lifting table hollow fender guard, comprise depression bar 2, straight connection rod 6, curved rod 7 and side plate 8, described depression bar 2 one ends pass the base 1 of lifting table and stretch out from the upper surface of base 1, the other end of depression bar 2 and straight connection rod 6 are connected by rotating shaft, the other end of straight connection rod 6 is connected with curved rod 7 by rotating shaft, and the other end of curved rod 7 is connected with side plate 8 by rotating shaft; One end diameter of described depression bar 2 protuberate basic units 1 increases and forms the single order halfpace, the part that diameter is little on the depression bar 2 is equipped with spring block 5, described spring block 5 is fixed in the base 1, is provided with retracing spring 4 between spring block 5 and the ladder platform, and retracing spring 4 is nested with on depression bar 2; The both sides that are located at base 1 below of described side plate 8 symmetries, the inboard of side plate 8 one ends is connected with a control desk 9, and the position of corresponding control desk 9 is respectively equipped with one stroke switch 10 in the base 1.
Under the normal condition, when lifting table was walked on the level land, if work top is in the state of rise, then side plate 8 was in the state vertical with the lower surface of base 1, shown in Fig. 1 left-half; If work top is in the minimum state that drops to, the pressing plate 3 that is connected the lifting part can press down depression bar 2, depression bar 2 moves down and drives straight connection rod 6, curved rod 7 and side plate 8 generation corresponding action, and side plate 8 is in the state parallel with the lower surface of base 1, shown in Fig. 1 right half part.The stroke of side plate 8 is 90 °, the rotation of side plate 8 can drive control desk 9 and move, and along with the difference meeting contacting travel switch 10 of control desk 9 positions, travel switch 10 has been controlled the walking of road wheel, control desk 9 touches travel switch 10 when it is pressed, and the road wheel of lifting table can not be walked.
