[0002] The forklift's fork frame is an important part of the forklift used to carry goods. Its function is to lift the goods from the ground and then hang them on the forklift for easy handling, stacking or loading and unloading. The structure of the fork frame is mainly composed of forks, fork brackets, hydraulic cylinders, hydraulic systems and control systems. The fork is the main part of the forklift used to carry goods, usually composed of two parallel fork arms. The front end of the fork arm is usually equipped with a fork blade, which is used to insert under the goods to lift the goods. The rear end of the fork arm is connected to the hydraulic cylinder, and the lifting and lowering of the fork arm is controlled by the extension and retraction of the hydraulic cylinder. When the operator operates the lifting and lowering of the fork through the control system, the control valve will open or close the hydraulic valve of the hydraulic cylinder, and the hydraulic oil will be sent into or discharged from the hydraulic cylinder, thereby controlling the piston movement of the hydraulic cylinder to realize the lifting and lowering of the fork. However, the current fork is usually a structure of two parallel fork arms. When the staff needs to add one or more fork arms to the forklift frame to increase the supporting area for the goods, this type of forklift frame is difficult to meet the needs.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: a forklift frame joint, comprising a forklift frame body 1 and a right-angle fork arm 2 clamped on the outer wall of one side of the forklift frame body 1, the right-angle fork arm 2 comprising a straight arm 201 arranged on one side of the forklift frame body 1, and a vertical arm 202 installed on one side of the top end of the straight arm 201, the straight arm 201 and the vertical arm 202 can provide good support and stability and withstand a large load;

[0018] A rectangular plug-in slot 4 is provided on the back of the forklift frame body 1, and a C-shaped double-layer plate 3 is fixed on the outer wall of one side of the vertical arm 202 close to the forklift frame body 1, and the C-shaped double-layer plate 3 that is mutually clamped with the rectangular plug-in slot 4 is fixed on the back of the right-angle fork arm 2. A hollow box 5 is fixed on the back of the right-angle fork arm 2, and a U-shaped bolt 8 is slidably installed on the top and bottom of the hollow box 5. The interior of the hollow box 5 is provided with a cavity for the U-shaped bolt 8 to enter. The top of the C-shaped double-layer plate 3 is provided with a through hole that completely penetrates itself. When the forklift frame body 1 and the right-angle fork arm 2 are clamped by the C-shaped double-layer plate 3, the U-shaped bolt 8 and the through hole are concentric with each other, and a nut sleeve 9 is installed on the top of the U-shaped bolt 8, and the U-shaped bolt 8 and the C-shaped double-layer plate 3 are bolted by the nut sleeve 9;

[0019] A horizontal column is fixed on the outer wall of one side of the forklift frame body 1 close to the right-angle fork arm 2, and the outer diameter of the horizontal column is equal to the inner diameter of the C-shaped double-layer plate 3. The opening of the C-shaped double-layer plate 3 is stuck on the steel column on the front of the forklift frame body 1;

[0020] Sliding buttons 6 are slidably mounted on both sides of the surface of the hollow box 5, and elastic limiting structures 10 are provided on the top wall and the bottom end of the hollow box 5. The elastic limiting structures 10 are used to connect the sliding buttons 6 and the U-shaped bolts 8;

[0021] The elastic limiting structure 10 includes two symmetrical coil springs 1003 installed on the top and bottom walls of the hollow box 5, and a sliding plate 1001 is installed at the ends of the two coil springs 1003 in the same X-axis direction. One end of the sliding plate 1001 close to the coil spring 1003 is fixedly connected to the bottom end of the U-shaped bolt 8, and a right-angle plate 1002 is fixed to the top of the sliding plate 1001. The top of the right-angle plate 1002 penetrates the outside of the hollow box 5 and is fixed with a connecting block 7. The top of the connecting block 7 is fixedly connected to the bottom end of the U-shaped bolt 8. When the staff manually applies force and makes the U-shaped bolt 8 sink into the hollow box 5, the staff pulls the right-angle plate 1002, the sliding plate 1001 and the U-shaped bolt 8 to slide down through the sliding button 6. At this time, the sliding plate 1001 moves down together under the drive of the right-angle plate 1002, and the coil spring 1003 is in a stretched state, generating elastic force by itself.

[0022] A rectangular hollow portion is provided on the surface of the hollow box 5, and a sliding column is slidably installed inside the rectangular hollow portion. One end of the sliding column is fixedly connected to the back of the sliding button 6, and the other end of the sliding column is fixedly connected to the surface of the right-angle plate 1002. When the end of the U-shaped bolt 8 is concentric with the through hole inside the C-shaped double-layer plate 3, the staff releases the sliding button 6, and the spiral spring 1003 begins to reset, and then the end of the U-shaped bolt 8 passes through the C-shaped double-layer plate 3. At this time, the staff can use the nut sleeve 9 to tighten the U-shaped bolt 8 and the C-shaped double-layer plate 3, thereby completing the addition and arrangement of the right-angle fork arm 2, and the operation is quick and convenient, which can meet the staff's needs for quick disassembly and quick installation in on-site operations.

[0023] When the embodiment of the present application is in use, the staff first opens a rectangular insertion groove 4 on the back of the forklift frame body 1, and then takes out the pre-processed right-angle fork arm 2, so that the C-shaped double-layer plate 3 on the back of the right-angle fork arm 2 is inserted into the rectangular insertion groove 4, and the opening of the C-shaped double-layer plate 3 is stuck on the steel column on the front of the forklift frame body 1. At this time, the two end plates of the C-shaped double-layer plate 3 pass through the forklift frame body 1. During this operation, the staff needs to manually operate the two sliding buttons 6 so that the two sliding buttons 6 are close to each other, and the connecting block 7 and the U-shaped bolt 8 are immersed in the hollow box 5, and the elastic limiting structure 10 is in an elongated and deformed state. When the right-angle fork arm 2 is connected to the forklift frame body 1 through the C-shaped double-layer plate 3, the staff releases the sliding button 6 again, and the elastic limiting structure 10 The deformation is restored and the two ends of the U-shaped bolt 8 pass through the outside of the C-shaped double-layer plate 3, and then the staff can bolt the U-shaped bolt 8 and the C-shaped double-layer plate 3 through the nut sleeve 9. At this time, the right-angle fork arm 2 is firmly installed on the forklift frame body 1 through the C-shaped double-layer plate 3, the U-shaped bolt 8, the elastic limiting structure 10 and other components, thereby increasing the load-bearing and supporting area of ​​the forklift frame body 1 for the goods, so that the forklift can more easily carry goods of different shapes and sizes. This can improve the versatility of the forklift and make it adapt to more types of goods. Compared with redesigning and transforming the entire forklift frame to increase the fork arm, the transformation cost and time can be reduced through simple grooving, plugging and bolting processing, and the fork arm can be increased without replacing the entire forklift, thereby reducing the cost.
