[0004] During use, it was found that the device only fixes the top frame with limiting blocks, resulting in poor stability of the top frame. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a detachable overhead guard for off-road forklifts.

[0006] This utility model discloses a detachable top guard for off-road forklifts, comprising a main guard and a secondary guard, with a secondary guard mounted on each main guard. It also includes a top guard assembly and a locking assembly. The top guard assembly is mounted on the top of the two main guards, and the locking assembly is also mounted on the top of the two main guards, locking the top guard assembly in place. The main and secondary guards are mounted on the forklift. When the top guard assembly needs to be opened, the operator releases the locking assembly from the top guard assembly, allowing the operator to open it. After use, the top guard assembly has a self-closing function. After closing, the locking assembly automatically locks the top guard assembly in place, improving its stability.

[0007] Preferably, the top frame assembly includes ear seats, positioning pins, a top frame body, a handle, and a slot. Each set of main guards has a set of ear seats at its top. The top frame body is rotatably connected to the two sets of ear seats by two sets of positioning pins. The bottom of the top frame body has a handle, and the front of the top frame body has a slot. A torsion spring is fitted on the positioning pin. In normal conditions, the torsion spring keeps the top frame body horizontal, and the top frame body seals the tops of the two sets of main guards. The locking component engages with the slot, moving away from the slot. The operator holds the handle to open the top frame body. After use, the torsion spring seals the tops of the two sets of main guards again. When the top frame body needs to be replaced, the positioning pins can be pulled out to disassemble the top frame body, improving its stability and convenience.

[0008] Preferably, the mounting assembly includes a fixing plate, insert rods, guide wheels, limiting plates, springs, and connecting plates. Each main support frame has a fixing plate at its top, with insert rods slidably mounted on each fixing plate. Each insert rod has a limiting plate, and a spring connects the fixing plate and the adjacent limiting plate. A guide wheel is located at the end of the insert rod closest to the ear seat, and the ends of both insert rods furthest from the ear seat are connected to one end of the connecting plate. In use, the operator inserts the two sets of insert rods into the slots of the main frame body to mount the main frame. When the main frame body needs to be opened, the connecting plate is pulled away from the main frame body, disengaging the two sets of insert rods from the slots, allowing the main frame body to open freely, thus improving convenience.

[0009] Preferably, it also includes a chamfered portion, and the top frame body is provided with a chamfered portion; when the top frame body re-seals the top of the two sets of main guards, the chamfered portion rolls into contact with the two sets of guide wheels, thereby causing the insertion rod to move away from the top frame body for operation. When the insertion rod coincides with the slot, the limiting plate causes the insertion rod to be inserted into the slot under the action of the spring force, completing the automatic locking.

[0010] Preferably, it also includes a handle cover, on which the handle is fitted; the operator grips the handle with the handle cover to reduce the occurrence of slippage.

[0011] Preferably, it also includes a buffer pad, and the bottom end of the top frame body is provided with a buffer pad; when the top frame body seals the top of the two sets of main protective frames, the buffer pad prevents the top frame body from making hard contact with the top of the main protective frames, thereby improving the service life.

[0012] Preferably, the main guard and the secondary guard are integrally formed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the main guard and the auxiliary guard are installed on the forklift. When it is necessary to open the top frame assembly, the operator releases the locking component from the top frame assembly and opens the top frame assembly. After use, the top frame assembly has a self-closing function. After closing, the locking component automatically locks the top frame assembly, improving its firmness. Attached Figure Description
