[0006] The file shelf has two modes of motor and hand wheel to drive the walking wheel, can realize the convenient movement of the file, thereby realizing the centralized management of multiple file shelves, densely placing, moving away the centralized file shelf, facilitating the reference, reducing the floor area of the file shelf as a whole, and improving the efficiency of archive storage and management.

[0007] Chain wheels are arranged on the transmission shaft and the rotating shaft of the hand wheel, and a roller chain is arranged between the two chain wheels. The chain transmission structure is stable and reliable, can bear a large torque, thereby realizing the rotation of the transmission shaft driven by the hand wheel, and the use of the roller chain improves the transmission efficiency and service life.

[0008] A supporting sleeve is arranged on the shelf body, and the hand wheel is rotatably arranged in the supporting sleeve, thereby providing stable support for the hand wheel, enhancing the stability of the hand wheel, making the hand wheel more stable during rotation, and reducing vibration and noise.

[0009] Further comprising guide rails capable of cooperating with the walking wheels, the guide rails are laid on the ground, and the walking wheels rollingly cooperate with the guide rails. The guide rails make the movement of the file shelf more stable and accurate, reduce the friction between the walking wheels and the ground, and prolong the service life.

[0010] The walking wheel comprises a base wheel, and a blocking edge is arranged on the left and right sides of the base wheel and extends radially outward from the base wheel. The blocking edge can prevent the walking wheel from falling off the guide rail during movement, thereby improving the stability of the file rack.

[0011] The guide rail comprises a base, and a limiting edge is arranged on the upper side of the base and protrudes upward. The base wheel is pressed against the upper part of the limiting edge, and the blocking edge is arranged on the left and right sides of the limiting edge. The cooperation between the base wheel and the limiting edge also reduces the friction between the walking wheel and the guide rail, thereby improving the movement efficiency.

[0012] A wheel cover for covering the walking wheel is mounted on the chassis, and the walking wheel is located at the lower part of the wheel cover. The wheel cover can protect the walking wheel from external environmental interference and damage, and also reduces noise and dust pollution.

[0013] A protective shell is mounted on the chassis, and the protective shell comprises two upper and lower half shells, and the motor is located in the two half shells. The protective shell provides good protection for the motor, prevents the motor from being eroded by external factors such as dust and moisture, and improves the service life and reliability of the motor.

[0014] A bearing is mounted in the chassis, and the transmission shaft is rotatably mounted on the chassis through the bearing. The bearing can reduce the friction and resistance of the transmission shaft during rotation, thereby improving the transmission efficiency and precision. At the same time, the bearing also has good carrying capacity and durability, which provides protection for the long-term stable work of the transmission shaft.

[0015] In summary, the file rack can realize centralized storage and management of multiple file racks, and some file racks can be removed for reference, which has the advantages of reducing the overall floor area of the file rack and improving the efficiency of file storage and management.

[0027] A movable file rack, comprising a frame body 1, the bottom of the frame body 1 is provided with an underframe 7, a transmission shaft 5 is rotatably installed in the underframe 7, a walking wheel 6 is installed on the transmission shaft 5, the lower edge of the walking wheel 6 protrudes outward from the bottom of the frame body 1, a motor 8 for driving the transmission shaft 5 to rotate is installed in the frame body 1, and a hand wheel 3 for driving the transmission shaft 5 to rotate is rotatably installed in the frame body 1. Referring to the accompanying drawings Figure 1The file rack has two driving methods for the walking wheels 6: motor 8 and handwheel 3, which can realize the convenient movement of files, thereby enabling centralized management of multiple file racks and dense placement. It can also move the concentrated file racks away for easy access. It has the advantages of reducing the overall footprint of the file rack and improving the efficiency of file storage and management.

[0028] See attached document Figure 3 Appendix Figure 4 Both the drive shaft 5 and the rotating shaft of the handwheel 3 are equipped with sprockets 9, and a roller chain 4 is installed between the two sprockets 9. The chain drive structure is stable and reliable, and can withstand large torques, thus enabling the handwheel 3 to drive the drive shaft 5 to rotate. The use of the roller chain 4 improves the transmission efficiency and lifespan. A support sleeve 11 is installed on the frame 1, and the handwheel 3 is rotatably mounted in the support sleeve 11, providing stable support for the handwheel 3, enhancing the stability of the handwheel 3, making the handwheel 3 rotate more smoothly, and reducing vibration and noise.

[0029] See attached document Figure 1 It also includes a guide rail 2 that mates with the wheels 6. The guide rail 2 is laid on the ground, and the wheels 6 roll in conjunction with the guide rail 2. The guide rail 2 makes the movement of the filing cabinet smoother and more accurate, while reducing friction between the wheels 6 and the ground, thus extending its service life. See attached diagram. Figure 5 The traveling wheel 6 includes a base wheel 13, with retaining edges 12 on both sides of the base wheel 13, extending radially outward along the base wheel 13. The retaining edges 12 prevent the traveling wheel 6 from detaching from the guide rail 2 during movement, improving the stability of the file rack. The guide rail 2 includes a base 14, with a limiting edge 15 on its upper side. The limiting edge 15 protrudes upward, and the base wheel 13 presses against the upper part of the limiting edge 15.
