[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0033] Example 1, reference Figures 1 to 8 As shown in the figure, it is the first embodiment of the present invention, which provides a protective lifting forklift, and the device includes a driving element 100, including a base 101, a handle 102 connected to the base 101, a lifting frame 103 connected to the base 101, a slide groove 104 symmetrically opened on the lifting frame 103, a fixing rod 105 connected to the lifting frame 103, and a roller plate 106 symmetrically connected to the base 101, so as to facilitate lifting of goods;

[0034] The lifting element 200 includes a lifting plate 201 sliding on the fixing rod 105, and a limiting assembly 202 disposed on the lifting plate 201;

[0035] The supporting element 300 includes a supporting plate 301 disposed on the limiting component 202, a sliding groove 302 provided on the supporting plate 301, and a control component 303 disposed on the supporting plate 301, so as to realize the transport of goods of various sizes;

[0036] The resistance element 400 includes a bracket 401 disposed on the limiting assembly 202, a rectangular slot plate 402 connected to the bracket 401, and a resistance assembly 403 disposed on the bracket 401, thereby preventing the cargo from tipping over.

[0037] The lifting plate 201 is controlled by an external control system so that the lifting plate 201 can slide back and forth on the fixing rod 105.

[0038] During use, before the goods are placed on the fork of the lifting forklift, the personnel adjust the support element 300 according to the size of the goods, so that the support element 300 can carry goods of various sizes. Then, the support element 300 controls the resistance element 400 to work, so that the resistance element 400 resists and fixes the placed goods, thereby preventing the goods from tipping over during the transportation process. Then, the lifting element 200 is adjusted by the driving element 100, so that the lifting element 200 can carry the goods to different heights.

[0039] Example 2, reference Figures 1 to 6 As shown, it is the second embodiment of the present invention, which is different from the first embodiment in that: the limiting component 202 includes a moving plate 202a connected to the lifting plate 201, a second slide groove 202b opened on the moving plate 202a, a slide groove 202c opened on the moving plate 202a, a rectangular plate 202f symmetrically slidably connected to the second slide groove 202b, a button 202e connected to the rectangular plate 202f, and a rectangular plate 202f symmetrically connected to the moving plate 202a, and the lifting element 200 realizes the effect of automatically adjusting the supporting element 300 and the resisting element 400.

[0040] Compared with the first embodiment, further, the movable plate 202a is slidably connected to the slide groove 104, the support plate 1 301 is fixedly connected to the slide groove 202c, and the size of the rectangular plate 1 202d is adapted to the size of the slide groove 202b.

[0041] It should be noted that the button 202e uses the power supply of the device to control the driving motor 403a to work, and the working principle of the slide slot 202c is similar to that of the electric slide. The electric slide uses the motor as its power source. When the electric slide receives a work instruction, the control system starts and controls the operation of the motor. The motor generates a rotational force through its internal electromagnetic action to provide power for the movement of the slide.

[0042] Compared with Example 1, further, the control component 303 includes a support plate 2 303a slidably connected to the inside of the slide groove 4 302, a fixed rod 2 303b arranged in a linear array and fixedly connected to the support plate 2 303a, a spring 1 303c sleeved on the fixed rod 2 303b, a telescopic plate 303d symmetrically connected to the support plate 1 301, and a rectangular plate 3 303e connected to the telescopic plate 303d, thereby achieving the effect of transporting goods of various sizes.

[0043] Compared with Example 1, further, the fixing rod 2 303b penetrates and slides inside the slide groove 4 302, the two ends of the spring 1 303c are respectively fixedly connected to the fixing rod 2 303b and the support plate 1 301, the support plate 2 303a is trapezoidal in shape, the size of the support plate 2 303a is adapted to the size of the slide groove 4 302, and the end of the rectangular plate 3 303e away from the support plate 2 303a slides on the inner side of the rectangular plate 1 202d.

[0044] During use, the personnel controls the slide slot 202c through an external control device, so that the slide slot 202c drives the support plate 1 301 to move to the middle position of the movable plate 202a, and adjusts the distance between the two support plates 1 301 through the slide slot 202c, so that the support plate 1 301 can carry goods of various sizes. When the distance between the two support plates 1 301 matches the size of the goods, the personnel controls the lifting plate 201 to slide upward on the fixed rod 105 through an external control device, so that the lifting plate 201 drives the movable plate 202a to slide upward on the lifting frame 103, and then the movable plate 202a drives the support plate 1 301 to move synchronously through the slide slot 202c;

[0045] During the upward sliding of the support plate 1 301, the support plate 1 301 drives the support plate 2 303a to move upward synchronously, so that the bottom of the support plate 2 303a contacts the goods, and the support plate 2 303a moves toward the inside of the slide groove 4 302 under the contact of the goods, so that the support plate 2 303a drives the fixing rod 2 303b to move synchronously, so that the fixing rod 2 303b stretches the spring 1 303c, and at the same time, the fixing rod 2 303b stretches the telescopic plate 303d through the rectangular plate 303e, so that the rectangular plate 303 The end of 3e on the inner side of the rectangular plate 202d presses the button 202e downwards, and at the same time, in the process of the slide groove 202c driving the support plate 301 to move, the support plate 301 drives the rectangular plate 303e to move synchronously through the fixed rod 2 303b, and then the rectangular plate 303e resists the rectangular plate 202d to move synchronously, and drives the support plate 301 to move through the slide groove 202c, thereby achieving the effect of automatically adjusting the distance between the two support plates 301, thereby achieving the effect of transporting goods of various sizes.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3, reference Figures 1 to 8 As shown, it is the third embodiment of the present invention, which is different from the second embodiment in that: the resistance component 403 includes a driving motor 403a connected to the bracket 401, a gear 403b symmetrically connected to the rectangular slot plate 402, a toothed belt 403c drivingly connected between the two gears 403b, a gear 403b connected to the side of the rectangular slot plate 402 away from the driving motor 403a for rotation, a slide groove 5 403e symmetrically opened on the fixed rod 3 403d, a cylindrical slider 403g arranged in a linear array and sleeved on the fixed rod 3 403d, a spring 2 403f connected between the two cylindrical sliders 403g, and a resistance plate 403h connected to the cylindrical slider 403g, thereby preventing the problem of tilting and overturning of goods during the process of lifting forklifts to transport goods.

[0048] Compared with Example 1, further, a resistance block is symmetrically arranged on the inner side of the cylindrical slider 403g, and the size of the resistance block arranged inside the cylindrical slider 403g is adapted to the size of the slide groove five 403e, the rectangular groove plate 402 and the support plate one 301 are both rotatably connected with the fixed rod three 403d, the driving end of the driving motor 403a is rotatably connected with the bracket 401, and the gear 403b arranged on the side of the rectangular groove plate 402 close to the driving motor 403a is fixedly connected to the driving end of the driving motor 403a, and the bracket 401 is fixedly connected to the rectangular plate two 202f.

[0049] It should be noted that four contact plates 403h are provided, and by adjusting the distance between the four contact plates 403h, the effect of contacting goods of different sizes can be achieved.

[0050] During use, when the slide slot 202c drives the support plate 1 301 to move toward the middle position close to the lifting frame 103, the support plate 1 301 contacts the cylindrical slider 403g, and at the same time, the cylindrical slider 403g squeezes the spring 2 403f to shrink. When the rectangular plate 303e presses the button 202e, the button 202e controls the drive motor 403a to start working, so that the drive motor 403a drives the gear 403b to rotate, and then the gear 403b drives the gear 403b away from the drive motor 403a to rotate synchronously through the toothed belt 403c, so that the gear 403b drives The fixing rod three 403d rotates between the two brackets 401 and the two rectangular slot plates 402, so that the fixing rod three 403d flips to the side close to the goods through the slide groove five 403e, and then the slide groove five 403e drives the contact plate 403h to flip synchronously to the side close to the goods through the cylindrical slider 403g, and makes the contact plate 403h contact with the goods, and finally the contact plate 403h flips and contacts with the goods, thereby avoiding the problem of the forklift driving on an uneven road surface and causing the tilting and overturning of the goods due to the imbalance of the support point, which not only improves the working efficiency of the forklift transportation, but also ensures the safety of the goods.
