[0006] The fixing base includes a first base plate, a first side plate and a first back plate. The first side plate is vertically fixed to both the left and right sides of the first base plate, and the back plate is fixedly connected between the first base plate and the first side plate.

[0007] The first movable seat is connected to the front side of the fixed seat through the first guide mechanism and can move back and forth. The first movable seat includes a second base plate and a second side plate. The second base plate is coplanarly disposed on the front side of the first base plate, and the second side plate is coplanarly disposed on the front side of the first side plate and is fixedly connected to the first base plate.

[0008] The second movable seat is connected to the upper side of the fixed seat through the second guide mechanism and can move up and down. The second movable seat includes a second back plate and a third side plate. The second back plate is coplanarly disposed on the upper side of the first back plate, and the third side plate is coplanarly disposed on the upper side of the first side plate and is fixedly connected to the second back plate.

[0009] With the above settings, the first movable seat can move back and forth to adjust the front and back width of the file rack, and the second movable seat can move up and down to adjust the height of the file rack, so that the file rack can support larger file bags.

[0010] Furthermore, the first guiding mechanism includes a first sleeve and a first guide rod. The first guide rod extends in a front-rear direction, with its front end fixedly connected to the second side plate and its rear end slidably connected in the first sleeve.

The second guide mechanism 11 is used to guide the second movable seat to move up and down stably.

[0033] When in use, the document bag is placed vertically in the document holder. The first side plate 4, the second side plate 8, and the third side plate 10 support the sides of the document bag to prevent it from tipping over. When a larger document bag needs to be inserted, the first movable seat moves forward, and the second movable seat moves upward. Figure 4 With the increased width and height of the file rack, file bags are less likely to tip over when placed inside.

[0034] As one implementation, the first guide mechanism 6 includes a first sleeve 61 and a first guide rod 62. The first guide rod 62 extends in the front-rear direction. The front end of the first guide rod 62 is fixedly connected to the second side plate 8, and the rear end of the first guide rod 62 is slidably connected in the first sleeve 61. The first sleeve 61 is fixedly connected to the first side plate 4.

[0035] In this application, the first guide mechanism 6 is specifically provided with four first guide rods 62 and four first sleeves 61. Two first guide rods 62 are provided on the outer side of the second side plate 8 on the left, and two first guide rods 62 are provided on the outer side of the second side plate 8 on the right. Two first sleeves 61 are provided on the outer side of the first side plate 4 on the left, and two first sleeves 61 are provided on the outer side of the first side plate 4 on the right. The rear end of the first guide rod 62 is slidably connected in the corresponding first sleeve 61.

[0036] As one implementation, the second guide mechanism 11 includes a second guide rod 111 and a second sleeve 112. The second guide rod 111 extends vertically, and its upper end is fixedly connected to the second back plate 9. The lower end of the second guide rod 111 is slidably connected in the second sleeve 112, and the second sleeve 112 is fixedly connected to the first back plate 5.

[0037] The second guide mechanism 11 of this application specifically includes two second light rods 111 and two second sleeves 112. The two second light rods 111 are arranged left and right, and their upper ends are fixedly connected to the outside of the second back plate 9. The two second sleeves 112 are arranged left and right, and are fixedly connected to the outside of the first back plate 5. The lower ends of the second light rods 111 are slidably connected to the corresponding second sleeves 112.

[0038] As one implementation, the file rack also includes a third light rod 12 extending vertically, with an elongated hole 13 provided along the axial direction of the first light rod 62. The upper end of the third light rod 12 is fixedly connected to the second side plate 8, and the third light rod 12 passes through the elongated hole 13.

[0039] The above-mentioned settings prevent the first light rod 62 from being pulled out of the first sleeve 61 and prevent the third side plate 10 from moving inside and outside.

[0040] The third optical rod 12 of this application is provided in two parts. The upper end of one third optical rod 12 is fixedly connected to the outside of the third side plate 10 on the left side, and the upper end of the other third optical rod 12 is fixedly connected to the outside of the third side plate 10 on the right side. The cross-section of the third optical rod 12 is rectangular, and the thickness of the third optical rod 12 is equal to the width of the elongated hole 13. The third optical rod 12 passes through the elongated hole 13 and fits against the side wall of the elongated hole 13 to prevent the third side plate 10 connected to the upper end of the third optical rod 12 from moving inward and outward, thereby improving the stability of the third side plate 10. The third optical rod 12 acts as a pin. When the first moving seat moves forward, when the end of the elongated hole 13 away from the second side plate 8 abuts against the third optical rod 12, the rear end of the first optical rod 62 is still in the first sleeve 61 to prevent the first optical rod 62 from being pulled out of the first sleeve 61.

[0041] As one implementation, the file holder also includes a first magnet 14, which is fixedly connected to the side of the third optical rod 12 and can be attracted to the lower side of the first optical rod 62.

[0042] With the above settings, after the second movable seat moves upward, the first magnet 14 fixes the height of the second movable seat to prevent it from falling.

[0043] like Figure 3 Initially, the third side plate 10 is close to the first side plate 4, and the first magnet 14 is positioned between the upper and lower first optical rods 62.

[0046] like Figure 3 Initially, the second side plate 8 is close to the first side plate 4, and the third smooth rod 12 is close to the end of the elongated hole 13 that is close to the second side plate 8, as shown. Figure 4 The first movable seat moves forward, and the second magnet 15 moves toward the third optical rod 12 and attracts the third optical rod 12, making it difficult for the first movable seat to move back and forth, thus fixing the width of the file holder.

[0047] As one implementation method, weight reduction holes 16 are provided on the first side plate 4, the second side plate 8, the third side plate 10, the first back plate 5, and the second back plate 9.

[0048] With the above configuration, the weight reduction hole 16 saves material for the fixed base, the first movable base and the second movable base, thus reducing the weight of the file holder.

[0049] As one implementation method, the fixed base, the first movable base, and the second movable base are all made of plastic.
