[0044] Reference Figures 1-5 A forklift structure with a supporting effect includes a frame 1, a mast component 2, fork components 3, and a telescopic support assembly 4. The mast component 2 includes an outer frame 21, an inner frame 22, and a first push rod component 23. The outer frame 21 is located on one side of the frame 1. The first push rod component 23 is disposed inside the outer frame 21 and connected to the inner frame 22. Two sets of fork components 3 are provided and distributed on the inner frame 22. The fork components 3 are used for loading goods. Two sets of telescopic support assemblies 4 are provided and distributed on both sides of the inner frame 22. The telescopic support assembly 4 is used to support the goods from the side.

[0045] The fork assembly 3 includes a fork plate 31 and an extension plate 32. The inner frame 22 has a crossbar 221. The fork plate 31 is movably mounted on the crossbar 221. The fork plate 31 has two sets of spaced-apart fork plates. By moving the fork plate 31 on the crossbar 221, the distance between the two sets of fork plates 31 can be adjusted. The end of the fork plate 31 away from the inner frame 22 has an opening 311. A support rod 312 is provided in the opening 311. The extension plate 32 is rotatably mounted on the support rod 312. When the extension plate 32 rotates on the support rod 312, a support area for the material is formed between the extension plate 32 and the fork plate 31. When the end face of the extension plate 32 is perpendicular to the end face of the fork plate 31, the extension plate 32 limits the goods, thereby avoiding the risk of the goods falling during movement.

[0046] The telescopic support assembly 4 includes a second push rod component 41 and a support seat 42. The piston end of the second push rod component 41 is connected to the support seat 42, so that the support seat 42 is located outside the inner frame 22. A material accommodating area is formed between the two sets of support seats 42. The second push rod component 41 drives the support seat 42 to move, and the accommodating area expands or shrinks. The fork component 3 is located between the two sets of support seats 42. When the fork component 3 carries goods, the goods are located in the accommodating area and abut against the support seat 42.

[0047] Based on the above structure, the first push rod component 23 in the mast component 2 of the machine body 1 moves the inner frame 22, on which the fork component 3 is installed, to a suitable position, and loads the forks through the fork component 3. When the goods are located inside the fork plate 31 of the fork component 3 and one end does not extend outside the fork plate 31, the extension plate 32 is rotated along the circumferential direction of the support rod 312 so that the extension plate 32 is perpendicular to the end face of the fork plate 31, thereby supporting the goods on one side. The second push rod component 41 in the telescopic support assembly 4 controls the support seat 42 to move toward the side of the goods until the end face of the support seat 42 abuts against the goods. Through the cooperation of the extension plate 32 and the telescopic support assembly 4, different end faces of the goods can be supported, thereby solving the problem that existing forklifts only clamp the goods, causing the goods to fall during movement, and reducing safety hazards during loading and handling.

[0048] Both the first push rod component 23 and the second push rod component 41 mentioned above adopt hydraulic push rods in the prior art.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 5 It also includes a third push rod component 5, which has two sets and is symmetrically distributed on the body 1. The piston end of the third push rod component 5 is connected to the outer frame 21. The third push rod component 5 is an electric push rod or a hydraulic push rod in the prior art.

[0050] A support 11 is provided at the bottom of the machine body 1 near the mast component 2. The support 11 has a movable cavity 111. Connecting rods 222 are provided on both sides of the outer frame 21. One end of the connecting rod 222 extends into the movable cavity 111 and is equipped with a roller component 223. The outer periphery of the roller component 223 abuts against the end face of the movable cavity 111. Through the cooperation of the third push rod component 5 and the roller component 223, the outer frame 21 can drive the inner frame 22 to move relative to each other. The extension and retraction of the third push rod component 5 drives the outer frame 21 to move, thereby causing the inner frame 22 to drive the fork component 3 to move relative to each other, thereby increasing the forklift's travel distance and further improving the forklift's flexibility when loading and unloading. Furthermore, by connecting the roller component 223 to the outer frame 21 via the connecting rod 222 and installing it in the movable cavity 111 of the support 11, the friction of the outer frame 21 during movement can be reduced, thereby facilitating the movement of the outer frame 21 and guiding its movement.

[0051] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 7The support base 42 has a recess 421, and the recess 421 has an elastic limiting component 6. The elastic limiting component 6 includes an elastic element 61, a baffle 62, and a guide rod 63. One end of the elastic element 61 is connected to the recess 421, and the other end is connected to the baffle 62. Several elastic elements 61 are provided and are spaced apart along the length direction of the recess 421. The elastic element 61 is a pressure spring or a telescopic spring in the prior art. Through the cooperation of the elastic element 61, the baffle 62 is moved closer to or away from the recess 421. When the goods are located between the two sets of support bases 42, the baffle 62 can abut against the side of the goods with the cooperation of the elastic element 61, thereby achieving support and limiting of the goods from both sides, thereby improving the stability of the goods during loading. Furthermore, according to the characteristics of the elastic element 61, the baffle 62 can be used for goods of different sizes and always abut against the side of the goods.

[0052] The guide rod 63 is located between the two sets of elastic elements 61 and is distributed at intervals. One end of the guide rod 63 is connected to the baffle 62, and the other end extends to the outside of the support base 42. Since the baffle 62 moves with the cooperation of the elastic elements 61, and the elastic elements 61 will deform when elastically compressed, the position of the baffle 62 will be offset when it moves. Therefore, by setting the guide rod 63, it can play a guiding role when the baffle 62 moves, thereby improving the stability of the baffle 62 when it moves.

[0053] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The top of the inner frame 22 is provided with a baffle assembly 7. The baffle assembly 7 is provided with a rod component 71 and a railing frame 72. The rod component 71 is provided on the top of the inner frame 22 and connected to the railing frame 72. Several rod components 71 are provided and distributed at intervals along the length direction of the baffle assembly. The baffle assembly 7 can support the top of the goods and prevent the center of gravity from shifting due to lack of support at the top of the goods under the action of gravity.

[0054] The pole component 71 includes a fixed pole 711 and a movable pole 712. The fixed pole 711 is mounted on the inner frame 22, and the movable pole 712 is connected to the guardrail frame 72. The fixed pole 711 has a groove, and one end of the movable pole 712 is embedded in the groove. The overall height of the pole component 71 is composed of the length of the fixed pole 711 and the portion of the movable pole 712 located outside the fixed pole 711. By moving the movable pole 712 within the groove, the position and height of the guardrail frame 72 are changed synchronously. Since different goods have different heights, by mounting the guardrail frame 72 on the movable pole 712, the position of the guardrail frame 72 can be adjusted according to the goods, thus achieving flexible adjustment of the height of the guardrail assembly 7 and improving the flexibility of use.

[0055] The baffle assembly 7 also includes a support pad 73, which is located on the side of the inner frame 22 away from the body 1. The support pad 73 covers part of the rod component 71. The support pad 73 is made of rubber. When the goods approach the inner frame 22, they first come into contact with the support pad 73. The support pad 73 can prevent the goods from directly contacting the inner frame 22, thus protecting the inner frame 22 and providing shock absorption for the goods.

[0056] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 7 The baffle 62 has a groove 621 at one end away from the recess 421. Several grooves 621 are provided and distributed at intervals along the length of the baffle 62. The grooves 621 form anti-slip patterns on the baffle 62. Since the baffle 62 will contact the side of the goods with the cooperation of the elastic member 61, the setting of several grooves 621 can increase the friction between the grooves 621 and the goods, thereby reducing the swaying of the goods when they move after contacting the baffle 62.

[0057] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6 The bottom of the fork plate 31 is provided with a limiting plate 313. The limiting plate 313 is located below the opening 311. When the extension plate 32 is selected to a certain angle, it will be blocked by the limiting plate 313, thereby limiting the extension plate 32 and allowing it to rotate only within a certain range.

[0058] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 4 The fork plate 31 has a wear-resistant pad 314 made of rubber. Since the fork plate 31 needs to support the goods to be clamped, the wear-resistant pad 314 can prevent the goods from damaging the end face of the fork plate 31 and improve the service life of the fork plate 31.
