[0061] The structure of the quick-installed spring clamping device 100 between plates of the utility model is as follows when it leaves the factory:

[0062] The quick-installed spring clamping device 100 between plates is already a component (such as Figure 1 ), the clamping bolt 2 is hinged on the base 1, the spring 3 is inserted into the first channel 12 from the back of the base 1, and the clamping bolt 2 is supported. One end of the spring 3 is hooked in the hook hole 14 on the side wall of the base 1, so that the assembly remains in a straight state. This operation process is completed by the manufacturer.

[0063] The specific installation steps of the utility model when applied are as follows:

[0064] Step 1: directly drive the quick-installed spring clamping device 100 between the panels into the mounting groove 2002 of the layer panel (i.e., the second panel 200), and ensure that all the clamping bolts 2 can be rotated 90 degrees toward the back panel (such as Figure 3 , Fig.15 shown);

[0065] Step 2: Place the layer plate (i.e., the second plate 200) between the two side plates (i.e., the first plate 200), push the layer plate (i.e., the second plate 200) into the two side plates (i.e., the first plate 200), move the layer plate (i.e., the second plate 200) from top to bottom or from bottom to top, align the clamping bolt 2 with the clamping groove 2001 of the side plate (i.e., the first plate 200), and the clamping bolt 2 will naturally be stressed by the spring so as to be parallel to the side (i.e., the first plate 200) of the layer plate (i.e., the second plate 200). Fig.15 Then, the laminate (i.e., the second sheet 200) is pressed downward until it is firmly clamped (as shown in FIG. Fig.16 shown);

[0066] The disassembly process of this utility model is as follows:

[0067] Hold the layer board (i.e. the second plate 200) with both hands, lift it up, and then move the clamping bolt 2 horizontally to the rightmost end of the "L"-shaped groove of the clamping groove 2001 of the side plate (such as the first plate 200), so that the clamping bolt 2 is bent and stored, and then the layer board (i.e. the second plate 200) can be moved out.

[0068] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model.
