[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 6 As shown, a hand-pushed electric forklift that can be raised and lowered is provided in one embodiment of the utility model, comprising a forklift structure 1 and a lifting arm 10;

[0025] The upper inner wall of the forklift structure 1 is fixedly connected to a pulley assembly 2, and the outer wall of the pulley assembly 2 is provided with a fixing rope 3. One end of the fixing rope 3 is fixedly connected to a fixing block 4, and the lower end of the fixing block 4 is fixedly connected to a magnet block 5. The lower inner wall of the forklift structure 1 is fixedly connected to an electromagnet 19, and the other end of the fixing rope 3 is fixedly connected to a lifting block 7;

[0026] The inner wall of the lifting arm 10 is fixedly connected to the rotating rod 1001, and the inner wall of the lifting arm 10 close to the rotating rod 1001 is fixedly connected to the return spring 11, the upper end of the return spring 11 is fixedly connected to the pressing plate 12, the outer wall of the pressing plate 12 is fixedly connected to the fixing rod 13, the outer wall of the fixing rod 13 is rotatably connected to the first lifting plate 14, the outer wall of the first lifting plate 14 is fixedly connected to the second lifting plate 15, the outer wall of the second lifting plate 15 is rotatably connected to the connecting block 16, and the upper end of the connecting block 16 is fixedly connected to the pressure plate 17.

[0027] The utility model provides a hand-pushed electric forklift that can be raised and lowered. When the object is lifted and transported, the pressing plate 12 is pressed downward by the arrangement of a rotating rod 1001, a return spring 11, a pressing plate 12, a fixing rod 13, a first lifting plate 14, a second lifting plate 15, a connecting block 16 and a pressure plate 17. The pressure plate 17 is moved upward by the action of the first lifting plate 14 and the second lifting plate 15, and fits with the lower end of the object to increase the friction resistance and improve the stability of its support. When the object is lifted to the highest point, the magnetic block 5 will descend through the fixing rope 3 and contact the electromagnet 19. The electromagnet 19 is energized to generate a magnetic force to magnetically attract the magnetic block 5, limit the lifting block 7, increase the load capacity of the lifting frame 9 and the lifting arm 10, and extend the service life.

[0028] In the embodiment of the utility model, when in use, the hydraulic lifting assembly 6 lifts the lifting arm 10 upward through the lifting block 7 and the lifting frame 9. Since the pressing plate 12 contacts the lower end of the lifted object and is affected by pressure, it will retract and contract downward through the return spring 11, and at the same time press the first lifting plate 14 downward, and the second lifting plate 15 is subjected to the force of the first lifting plate 14, and the pressure plate 17 is lifted upward through the connecting block 16, and fits with the lower end of the object, thereby increasing the friction resistance to its support and increasing the stability when moving the object. When the object is lifted to the highest point, the fixed block 4 moves to the lowest position through the fixed rope 3, and energizes the electromagnet 19 so that it is magnetically adsorbed with the magnet block 5, and the lifting block 7 is pulled by the fixed rope 3, thereby reducing the influence of the gravity of the object on the lifting arm 10, increasing the load capacity of the lifting arm 10, and making it more effective in use.

[0029] like Figure 2As shown, as a preferred embodiment of the present invention, one end of the forklift structure 1 is fixedly connected to a support arm 18, which can support the lifting arm 10 so that it will not contact the ground when not in use, reducing the probability of damage by collision, and can also clamp and carry items. The other end is fixedly connected to a counterweight block 20 to increase the stability of the forklift structure 1 and reduce the probability of overturning due to excessive weight of the items being carried. The end away from the upper surface of the counterweight block 20 is fixedly connected to a push handle 21 to facilitate pushing the forklift structure 1.

[0030] like Figure 3 As shown, as a preferred embodiment of the present invention, the inner wall of the forklift structure 1 away from the electromagnet 19 is fixedly connected to a hydraulic lifting assembly 6, the upper end of the hydraulic lifting assembly 6 is fixedly connected to a lifting block 7, the lower end of the lifting block 7 is fixedly connected to a lifting frame 9, and one end of the lifting frame 9 is fixedly connected to a lifting arm 10, which is a power lifting structure of the forklift structure 1. The lifting arm 10 can be raised or lowered by the hydraulic force, thereby transporting and stacking items.

[0031] like Figure 1 and Figure 3 As shown, as a preferred embodiment of the present invention, the forklift structure 1 is provided with an outer slide groove 22 at one end close to the outer wall of the support arm 18, so that the lifting frame 9 slides through the outer slide groove 22 to increase the stability of movement, and the forklift structure 1 is provided with an inner slide groove 23 on the inner wall away from the lower end of the pulley assembly 2, so that the outer wall of the lifting block 7 slides through the inner slide groove 23 to increase the stability of movement.

[0032] like Figure 6 As shown, as a preferred embodiment of the present invention, the inner wall of the first lifting plate 14 is rotatably connected to the rotating rod 1001, and is rotatably connected to the lifting arm 10 through the rotating rod 1001. The pressure plate 17 is rotatably connected to the second lifting plate 15 through the connecting block 16. By moving the pressure plate 17 downward, the first lifting plate 14 can lift the pressure plate 17 upward through the second lifting plate 15 and the connecting block 16, contacting the lower end of the transported item, and increasing the friction resistance to its support.

[0033] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the number of the reset springs 11 is several groups, which can make the pressing plate 12 quickly reset by the force of the reset spring 11. The lower end of the forklift structure 1 and the support arm 18 is provided with a power wheel to facilitate the transportation of the lifted items. The number of the pressure plates 17 is four groups, which can increase the stability of the lifting and transportation of the items.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
