Technical field
The utility model relates to a kind of quick securing means technical field, refers more particularly to the securing means of fixed L ED display screen Direct box fast.
Background technique
In the time of on the Direct box of existing LED display and the box frame of LED display, generally be to adopt screw or nut to fix, need to finish, no matter be that installation or dismounting all need corresponding instrument to finish by relevant instrument.Troublesome poeration, inefficiency.
Summary of the invention
In sum, goal of the invention of the present utility model is avoided loose or dislocation after being to provide a kind of Direct box at LED display directly to be hung on box frame in the mode of linking up with, and the securing means of the quick fixed L ED display screen Direct box that can be locked fast.
For solving the technical problem that the utility model proposed, the technological scheme that adopts is: a kind of securing means of quick fixed L ED display screen Direct box, it is characterized in that: include an active baffle piece, on active baffle piece, be provided with L shaped locating slot, be provided with fastening screw in described L shaped chute, movable washer is connected it by fastening screw with a fixed base.
As being to the further improved technological scheme of the utility model:
Described L shaped locating slot is made up of guiding groove connected vertically and screens groove, and the left and right side of described active baffle piece is connected with the fixedly connected restraining groove of fixed base respectively; Described restraining groove is parallel with guiding groove, remains with between the left and right side of the bottom land of described restraining groove and active baffle piece for screw from the gap of guiding groove to the translation of screens groove.
Described guiding groove is vertical with the bottom side of active baffle piece.
The limit, top side of described active baffle piece is provided with handle.
The left and right side of described active baffle piece is connected with restraining groove to the spine folded back of active baffle piece.
The beneficial effects of the utility model are: the utility model is installed on the top of the Direct box on the box frame, Direct box articulate finish after, the promotion active baffle piece moves down, after the bottom side of active baffle piece is depressed into the Direct box top, horizontal mobile active baffle piece, the screens groove is cooperated with fastening screw, manually turn tightening nut, can realize the effect of quick lock in Direct box; Operating procedure is opposite during dismounting, can realize quick release, and Direct box is taken off; The utility model need not just can be finished the dismounting operation fast by any instrument, and is easy to use, effectively increases work efficiency.

Embodiment
Be further described below in conjunction with accompanying drawing and the structure of preferred specific embodiment model utility:
Shown in Fig. 1, Fig. 2 and Fig. 4, the utility model includes an active baffle piece 3, on active baffle piece 3, be provided with L shaped locating slot 31, L shaped locating slot 31 is made up of mutual guiding groove 312 connected vertically and screens groove 311, guiding groove 312 is vertical with the bottom side of active baffle piece 3, screens groove 311 is connected with the top of guiding groove 312 is vertical, decides to be inserted with one piece of fastening screw 5 in the groove 31 L shaped, and the screw front end of fastening screw 5 is screwed in the screw hole of a fixed base 4.When fastening screw 5 was tightened, active baffle piece 3 was fixedlyed connected with fixed base 4; When fastening screw 5 was unscrewed, connection activity washer 3 was subjected to can upper and lowerly to move under the effect of L shaped locating slot 31, also can move horizontally after moving to minimum point.
On fixed base 4, be fixedly connected with the restraining groove 41 parallel with guiding groove 312, restraining groove 41 can be to be directly arranged on the fixed base 4, also can be located on the box frame 2 of LED display, the left and right side of active baffle piece 3 is connected with restraining groove 41 to its spine folded back.When restraining groove 41 alleviates the active force of fastening screw 5, prevent to rotate at light fastening screw 5 active baffle piece 3 when unscrewing.Move horizontally normally in order not influence active baffle piece 3, remain with the free gap between the bottom land of restraining groove 41 and active baffle piece 3 left and right sides.For the ease of mobile active baffle piece 3, on the limit, top side of active baffle piece 3, be provided with handle 32.
Shown in Fig. 1, Fig. 2 and Fig. 3, working principle of the present utility model is: the step that the Direct box 1 of LED display is fixedly mounted on the box frame 2 is: at first, the hook at Direct box 1 back side is mounted on the box frame 2; Then, move down active baffle piece 3, when active baffle piece 3 when the effect of guiding groove 312 and fastening screw 5 moves down into minimum point, move horizontally active baffle piece 3, screens groove 311 is cooperated with fastening screw 5, the direction of screens groove 311 is horizontally disposed, fastening screw 5 is in screens groove 311 time, active baffle piece 3 can only move horizontally, and stops active baffle piece directly to move up, because of needs with Direct box 1 when box frame 2 takes off, Direct box 1 upwards must be lifted, active baffle piece 3 retainings are when Direct box 1 top, and Direct box 1 just can't take off, and reaches the purpose of quick lock in; At last, tighten tightening nut 5, avoid active baffle piece 3 to move horizontally, tightening nut 5 is provided with anti-skidding line, and directly manually-operable need not any instrument, and is easy to use.During dismounting, step is opposite.
