Further, driver plate is two, relative being installed on fixedly in the frid.
Further, the quantity of alignment pin is one or two.
The beneficial effects of the utility model are: the upper and lower lock that a fastening screw can be controlled security door only is installed in door when mounted, and difficult drop-off, flexible operation are installed firmly, fastening screw inside is made from multiple components, the use inconvenience that prevents to get rusty and cause; The utility model also can enlarge the scope of application according to using needs to adjust length of steel wire rope to adapt to the security door of different size.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model,
Fig. 2 is the fixedly schematic diagram of frid of the utility model,
Fig. 3 is the schematic diagram of the utility model cover plate.
The figure number explanation:
1 panel, 2 fixing frids, 3 driver plates, 4 handles, 5 alignment pins, 6 cover plates, 7 wire rope, 8 guide pipes, 11 stroke grooves, 21 reference columns, 22 springs, 31 chutes, 32 draw-in grooves, 33 locating holes, 34 lugs
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of fastening screw, it is by panel 1, fixedly frid 2, driver plate 3, handle 4, alignment pin 5, cover plate 6 and guide pipe 8 are formed, panel 1 is provided with chute 31, handle 4 can switch in chute 31 mutually, the two ends of panel 1 bottom surface are fixed with stroke groove 11 respectively, the two ends of handle 4 can place in the stroke groove 11, fixedly frid 2 is welded on panel 1 bottom surface, fixedly frid 2 is provided with reference column 21, one end of handle 4 is packed on the reference column 21 of fixing frid 2 by chute 31, and replace and be located at fixedly semielliptic spring 22 tops of frid 2 inner bottom parts, handle 4 is provided with reference column 21, also be provided with chute 31 on the driver plate 3, end at driver plate 3 is provided with draw-in groove 32, the other end is provided with locating hole 33, also be provided with lug 34 on the driver plate 3, lug 34 is provided with reference column 21, draw-in groove 32 is installed on the reference column 21 of handle 4, chute 31 is sleeved on the reference column 21 of fixing frid 2, alignment pin 5 is connected on the locating hole 33 of driver plate 3 with wire rope 7, guide pipe 8 is sleeved on outside the alignment pin 5, thereby make alignment pin 5 more flexible, and can guarantee the vertical motion of alignment pin 5, alignment pin 5 bottoms are provided with a spring, one end of spring is resisted against alignment pin 5 bottoms, the other end is resisted against the inner bottom surface of guide pipe 8, and cover plate 6 is provided with chute 31 and locating hole 33, and cover plate 6 is contained on the reference column 21 of fixing frid 2 by locating hole 33 spiral shells, guarantee the fixedly stability of frid 1 interior each parts on the one hand, also play effect attractive in appearance on the other hand.Chute 31 is sleeved on the reference column 21 of lug 34; Driver plate 3 is two, relative being installed on fixedly in the frid 2; The quantity of alignment pin is one or two.
