Embodiment

See also shown in Figure 2.The utility model PC hardens and closes the structure of frame, comprises that a frame 20 has at least one stator 21, plural supporting

seat

22,23 and at least one fastening piece 24.Stator 21 and fastening piece 24 are the relative edge, and supporting

seat

22,23 is between stator 21 and fastening piece 24.In the present embodiment, stator 21 is to be extended by first side plate, 25 upper ends of frame 20, has a horizontal segment 211 to the bending of frame 20 inner side edge levels, and horizontal segment 211 bottoms have alignment pin 212.Second side plate 26 of first side plate 25, supporting

seat

22,23, fastening piece 24 and frame 20 extends upward by the base plate 27 of frame 20.Second side plate 26 is the relative edge of first side plate 25.Second side plate 26 has groove 261 with ccontaining fastening piece 24.Supporting seat 23 tops of contiguous fastening piece 24 have alignment pin 231.Fastening piece 24 tops have the coak 241 that protrudes to frame 20 inner side edges.Coak 241 upper ends have the inclined-plane 242 by its top, outside below inclination to the inside.

See also Fig. 3, shown in Figure 4.The alignment pin 231 of the supporting seat 23 of the alignment pin 212 of the utility model stator 21 and fastening piece 24 vicinities corresponds respectively to the button hole 31 or the slotted eye 32 of a PC plate 30.Supporting

seat

22,23 is respectively in order to be supported in the bottom of PC plate 30.

When the utility model makes PC plate 30 in conjunction with frame 20, be to make PC plate 30 button hole 31 on one side or the alignment pin 212 of horizontal segment 211 bottoms of slotted eye 32 socket stators 21 earlier, the lower end of PC plate 30 places supporting seat 22 upper ends; Make PC plate 30 another sides suppress the inclined-plane 242 of the coak 241 that fastens cramp 24 downwards again, make of the outer side edges skew of the upper end of fastening piece 24 to frame 20, and the another side that makes PC plate 30 passes through the coak 241 of fastening piece 24, make the alignment pin 231 of the supporting seat 23 of the contiguous fastening piece 24 of button hole 31 or slotted eye 32 sockets, original position is recovered in the upper end of fastening piece 24 simultaneously, makes its coak 241 be buckled in the outer side edges of PC plate 30 another sides.

Utilize the alignment pin 212 of stator 21 and the alignment pin 231 of supporting seat 23, reached downwards by the lower end by the upper end of a PC plate 30 respectively and buckle into upward in the button hole 31 or slotted eye 32 of PC plate 30, PC plate 30 is fixed can't move horizontally.Utilize the horizontal segment 211 of stator 21, the coak 241 of fastening piece 24 again, and supporting seat 22, the 23 upper and lower limit of clamping PC plates 30 respectively, make the PC plate 30 can't upper and lower vertical moving, make PC plate 30 and frame 20 firm combining, as shown in Figure 4.

In the time will making PC plate 30 break away from frame 20, the user is as long as make the lateral direction skew of fastening piece 24 upper ends to frame 20 with hand, make coak 241 break away from the position that fastens PC plate 30, the one side of up mentioning PC plate 30 again, make the another side of PC plate 30 tilt to break away from the restriction of stator 21 downwards, can easily make PC plate 30 break away from frames 20.

Fastening structure of the present utility model can be one-body molded with frame, do not need the part of extra purchase in conjunction with the PC plate, or other die sinking manufacturing is in conjunction with part, so escapable cost.The utility model does not need the instrument of other screw and lock screw, PC is hardened close or breaks away from frame, makes combination or the operation of taking apart is more convenient, more save time.
