For the way the fork lifts the goods, it is usually to directly lift the entire fork. However, for small and medium-sized automatic pallet trucks, wheels need to be installed on the bottom of the fork itself to balance the front and rear. It is difficult to directly lift the fork, so a new design is needed. The structure solves the technical problem of how to lift goods.

A front lead rod 233 extends from the other side of the front part of the moving member 23 . The second link 26 is hingedly connected to the end of the front lead rod 233 , and the second link 26 extends perpendicularly to the front lead rod 233 .
这里需要说明的是，在货叉内设置了两个凸轮25、27同时抵靠升降板22的前后端，能够使升降板22的升降前后稳定且受力均匀，是一种优选的方式。而在其他的的实施例中，也能够采用简化的结构，即只设置一个凸轮(位于货叉底盘中部位置)，而将升降板22在横向上定位，只能通过凸轮带动上下移动，这样也能够实现升降板22的升降。It should be noted here that two cams 25 and 27 are provided in the fork to simultaneously abut the front and rear ends of the lifting plate 22, so that the lifting and lowering of the lifting plate 22 can be stable and evenly stressed, which is a preferred method. In other embodiments, a simplified structure can also be adopted, that is, only one cam (located in the middle of the fork chassis) is provided, and the lifting plate 22 is positioned laterally and can only be driven up and down by the cam. This also The lifting plate 22 can be raised and lowered.
而移动件23的前后移动的方式通过以下结构实现。所述驱动主体10内设有电机11、与电机11输出轴12铰接的第一进给连杆13、横轴14、分别位于横轴14两端的两个第二进给连杆15。所述横轴14穿过第一进给连杆13并与第一进给连杆13共同转动。横轴14与电机输出轴12垂直。驱动主体10的底部内安装有两个横轴固定座141，所述横轴14穿过两个横轴固定座141，第一进给连杆13位于两个横轴固定座141之间。电机输出轴12铰接于第一进给连杆13一端，横轴14穿过第一进给连杆13另一端。电机输出轴12与第一进给连杆13铰接的位置高于横轴14与第一进给连杆13铰接的位置。还设有第三连杆16，该第三连杆16的一端铰接于移动件23上而另一端铰接于第二进给连杆15上，电机输出轴12向外推动第一进给连杆13，并通过横轴14将第二进给连杆15与第三连杆16的铰接处向前推动，第三连杆16即向前推动移动件23。所述两个第二进给连杆15分别与两个货叉内的第三连杆16铰接，即通过电机能够同时将两个货叉内的移动件23同向推动。The forward and backward movement of the moving member 23 is realized by the following structure. The driving body 10 is provided with a motor 11, a first feed link 13 hingedly connected to the output shaft 12 of the motor 11, a transverse shaft 14, and two second feed links 15 respectively located at both ends of the transverse shaft 14. The transverse axis 14 passes through the first feed link 13 and rotates together with the first feed link 13 . The horizontal axis 14 is perpendicular to the motor output shaft 12 . Two transverse axis fixing seats 141 are installed in the bottom of the driving body 10 . The transverse axis 14 passes through the two transverse axis fixing seats 141 . The first feed link 13 is located between the two transverse axis fixing seats 141 . The motor output shaft 12 is hingedly connected to one end of the first feed link 13 , and the horizontal axis 14 passes through the other end of the first feed link 13 . The position where the motor output shaft 12 is hinged to the first feed link 13 is higher than the position where the horizontal axis 14 is hinged to the first feed link 13 . A third link 16 is also provided. One end of the third link 16 is hinged to the moving member 23 and the other end is hinged to the second feed link 15. The motor output shaft 12 pushes the first feed link outward. 13, and push the hinge of the second feed link 15 and the third link 16 forward through the horizontal axis 14, and the third link 16 pushes the moving member 23 forward. The two second feed links 15 are respectively hinged with the third links 16 in the two forks, that is, the moving parts 23 in the two forks can be pushed in the same direction by the motor at the same time.
所述第一凸轮25的第一升降端253两侧安装有两个导引轮254，该两个导引轮254分别位于第一凸轮25的两侧且高度相同；所述第二凸轮27的第二升降端273两侧同样安装有两个导引轮274，该两个导引轮274分别位于第二凸轮27的两侧且高度相同。导引轮254、274能够使凸轮25、27与升降板22之间的接触变为滑动接触，有利于保持相互作用的稳定及减少磨损。Two guide wheels 254 are installed on both sides of the first lifting end 253 of the first cam 25. The two guide wheels 254 are respectively located on both sides of the first cam 25 and have the same height; the second cam 27 has Two guide wheels 274 are also installed on both sides of the second lifting end 273. The two guide wheels 274 are respectively located on both sides of the second cam 27 and have the same height. The guide wheels 254 and 274 can change the contact between the cams 25 and 27 and the lifting plate 22 into sliding contact, which is beneficial to maintaining the stability of the interaction and reducing wear.
