[0001] The utility model relates to the technical field of hydraulic valve bodies, in particular to a hydraulic valve body for a forklift. Background Art

[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles that load and unload, stack and transport palletized goods over short distances. They are often used to transport large objects in warehouses and are usually powered by fuel engines or batteries.

[0003] At present, the hydraulic valve body used in forklifts is mainly composed of multiple valve bodies of different models, and the multiple valve bodies are combined together by the cooperation of bolts and threaded holes. For example, an electric forklift valve body assembly disclosed in Chinese Patent Publication No. CN109336006B, but since the bolts are easy to rotate after being vibrated, the multiple valve bodies on the hydraulic valve body often become loose due to vibration. At the same time, since the angle between the mounting bracket fixed on the hydraulic valve body and the hydraulic valve body cannot be changed, the angle between the mounting bracket and the first valve body cannot be adjusted according to the installation requirements during the installation of the hydraulic valve body, thereby restricting the installation of the hydraulic valve body.

At the same time, when the baffle 10 is stuck in the first U-shaped plate 9, the first bolt 8 can be locked by the baffle 10.

[0028] The locking bracket 13 includes a first cylinder 131, and a bearing 132 is fixedly connected to the surface of the first cylinder 131 and the inner wall of the stepped hole 12, and a volute spring 133 is fixedly connected to the surface of the first cylinder 131 and the inner wall of the stepped hole 12, and an elliptical disk 134 is fixedly connected to the surface of the first cylinder 131, and the front and rear sides of the elliptical disk 134 are in contact with the inner wall of the first arc column 15, and the right side of the elliptical disk 134 and the surface of the first cylinder 131 are fixedly connected with a first rotating block 135.
