Specific implementation
[0022] The utility model will be further explained in detail in connection with the drawings.
[0023] Embodiment:
[0024] Refer to Figures 1-3 The utility model discloses a high-strength light-weight forklift novel composite frame, including chassis 1, the top side of chassis 1 is connected with rectangular frame 2, the opposite sides of rectangular frame 2 are seted up with side groove 3, and the top side both ends of rectangular frame 2 are seted up with mounting groove 4, and the side groove 3 is provided with positioning piece 5.
[0025] Positioning piece 5 includes lead core column 6, round hole 7, internal thread 8, insertion column 9, external thread 10 and limiting hole 11, both ends of lead core column 6 are seted up with round hole 7, and the one side close to the external portion of two round holes 7 is seted up with internal thread 8, the round hole 7 is inserted with insertion column 9, both ends of insertion column 9 are seted up with the external thread 10 corresponding with internal thread 8, the opposite two side walls of side groove 3 are seted up with limiting hole 11, insertion column 9 is inserted into limiting hole 11, and mounting groove 4 is inserted with mounting plate one 12, and both ends of mounting plate one 12 are seted up with the limiting groove one 13 corresponding with insertion column 9.
[0026] In the embodiment, observe Figure 1 The rectangular frame 2 can be installed on the top side of the chassis 1 by bolting or welding, and the top side of the mounting plate one 12 can be welded to the bottom side of the forklift mast. Figure 2Mounting plate 12 is inserted into the mounting slot 4 on the left side of the rectangular frame 2. Under normal circumstances, without external interference, mounting plate 12 and the gantry are confined within the mounting slot 4. Observe... Figure 2 The side groove 3 is then pushed into the lead core 6 so that the insert 9 on the conical core aligns with the limiting hole 11.
[0027] A hexagonal hole can be made at the end of the insert 9. A hexagonal screwdriver, which is magnetic, is inserted into the limiting hole 11 from the side of the rectangular frame 2. The screwdriver is then inserted into the hexagonal hole at the end of the insert 9 and rotated, causing the external thread 10 on the insert 9 to disengage from the internal thread 8 in the circular hole 7. [The text then abruptly shifts to a seemingly unrelated topic:] ...to observe... Figure 3 The internal thread 8 can be seen at the opening inside the round hole 7. Then, by using the magnetic attachment of the insert 9 on the hex screwdriver, it can be observed... Figure 2 The left-hand insert 9 is inserted into the limiting hole 11 to limit the mounting plate 12, which can quickly fix the mounting plate 12 and the gantry, improving installation efficiency.
[0028] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a limiting frame 14 is connected to the top of the rectangular frame 2, and the inner sidewall of the limiting frame 14 is attached to the outer sidewall of the mounting plate 12.

After the mounting plate 12 is inserted into the mounting groove 4, the top side wall of the mounting plate 12 fits against the inner side wall of the limiting frame 14. At this time, the inner side wall of the limiting frame 14 further limits the outer side of the mounting plate 12, thereby achieving the effect of reinforcing the mounting plate 12 and the forklift mast and improving its stability during use.
[0030] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a second mounting plate 15 is inserted into the mounting groove 4 away from the first mounting plate 12, and a second limiting groove 16 is provided at both ends of the bottom side of the second mounting plate 15.
[0031] In this embodiment, observation Figure 2Two installation grooves 4 are arranged in the rectangular frame 2, and installation plate one 12 and installation plate two 15 are arranged in the two installation grooves 4 respectively, installation plate two 15 can be directly welded with the shell of the battery, and the limitation of installation plate two 15 is the same as that of installation plate one 12, the corresponding plug post 9 is inserted into the limiting groove two 16, so that installation plate two 15 is limited, and the battery is limited.
[0032] In further preferable embodiments of the present application, as shown in Figures 2-3 The two round holes 7 are connected with push springs 17, and the end of the push spring 17 is fixedly connected with the corresponding plug post 9.
[0033] In this embodiment, it can be observed Figure 3 The push spring 17 is also connected in the round hole 7 of the plug post 9, and the initial state of the push spring 17 is compressed, and it can be observed Figure 2 In the plug post 9, after the plug post 9 is rotated by the hexagonal screwdriver and the external thread 10 on the plug post 9 is separated from the internal thread 8 in the round hole 7, the push spring 17 in Figure 3 The push spring 17 will push the plug post 9 to move in the direction of the limiting hole 11, so that when the hexagonal screwdriver is used, it is not necessary to carry a magnet, so that when the external thread 10 on the plug post 9 is separated from the internal thread 8 in the round hole 7, the plug post 9 can be quickly inserted into the limiting hole 11 and the limiting groove one 13 is limited, the installation plate one 12 is quickly limited, and the limiting of the installation plate two 15 is the same as the limiting of the limiting plate one.
[0034] In further preferable embodiments of the present application, as shown in Figure 1 Opposite two side edges of the edge groove 3 are provided with arc grooves 18, and the curvature of the arc groove 18 is the same as the curvature of the outer circumferential side of the lead core column 6.
[0035] In this embodiment, the arc groove 18 is observed Figure 1 When the lead core column 6 is placed, the outer circumferential side of the lead core column 6 can be directly attached in the arc groove 18, so that the round hole 7 and the limiting hole 11 can be aligned automatically, without hand holding, and the convenience during installation is improved.
[0036] The embodiments of the present application are preferable embodiments of the present application, and are not limited to the protection scope of the present application, so that: any equivalent changes made according to the structure, shape and principle of the present application should be covered in the protection scope of the present application.
