[0002] The telescopic fork is a commonly used device in the field of logistics warehousing. The picking, placing and handling of goods can be realized through the telescopic fork. The telescopic fork with adjustable fork spacing can adapt to goods of different sizes and shapes by adjusting the fork spacing, so as to meet the diverse needs of logistics and material handling and improve the flexibility of the telescopic fork. The use of the telescopic fork with adjustable fork spacing can effectively improve the logistics operation efficiency and space utilization rate, and at the same time can effectively reduce the transportation and transfer costs.

[0003] The existing telescopic fork with adjustable fork spacing includes a fork body assembly and a transmission assembly integrally installed with the fork body assembly. The transmission assembly and the fork body assembly are connected by a transmission shaft, and the transmission assembly drives the fork body assembly to adjust the spacing. It is difficult to disassemble and maintain the existing transmission assembly after assembly. In addition, in the case of a relatively large spacing adjustment range, a very long transmission shaft needs to be used. If the working environment is relatively narrow, the transmission shaft cannot be taken out and reinstalled, and once the telescopic fork fails, it cannot be repaired.

[0004] In summary, there is a need in the art to improve the transmission assembly of the existing telescopic fork with adjustable fork spacing to improve the convenience of disassembly and maintenance. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a transmission assembly for a telescopic fork with adjustable fork spacing, and the transmission assembly is detachably connected to the telescopic fork to facilitate disassembly and maintenance.

The gear component is combined and installed with the welded gearbox 10. The spline shaft component 15 is rotatably connected to the welded gearbox 10. The spline shaft component 15 is in transmission connection with the gear component and an external driving device. The gear component is in transmission connection with the gears inside the telescopic fork. The welded gearbox 10 is detachably connected to the telescopic fork. The transmission component for the telescopic fork with adjustable fork spacing can be installed and disassembled conveniently and quickly, can be quickly replaced in case of failure, helps to improve the operation efficiency, reduce the operation cost, and at the same time is convenient for troubleshooting, which helps to reduce the maintenance cost. See Figure 2 , the gear component is in transmission connection with the gears inside the lower fork body 2 of the telescopic fork.
