Abstract
The utility model discloses a kind of folders, including fixed plate, worm screw is rotatably connected in the plate face of fixed plate, the both ends of worm screw have been connected through a screw thread upper locking nut and lower locking nut, upper locking nut and lower locking nut are fixedly connected with fixed plate respectively, the end of wherein one end of worm screw is fixedly connected with handwheel, and the two sides at position are sequentially connected with one group of clamping device respectively among worm screw, and two groups of clamping devices cooperations complete that file is stepped up and unclamped；The utility model by adopting the above technical scheme, takes file convenient, while thicker file easy to setup, while the folder that can be opened and closed not the larger strength of expense.
Description
Technical field
The utility model relates to file administration apparatus, particularly relate to a kind of examination folder.
Background technique
File is clamped the spring pressing fixture that the clamping of file is usually used by existing folder, is being taken
When partial document, needs first firmly to unclamp spring perch, then the file of needs is taken out, presses fixture again later will remain
Under file clamp；It just needs to do folder when storing thicker file larger, needs just be overcome with biggish power
The power of spring opens and closes folder, inconvenient to use.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of folder, the folder accessing file sides
While thicker file easy to setup, while the folder that can be opened and closed not the larger strength of expense just,.
To solve the above problems, the utility model uses following technical scheme: a kind of folder, including fixed plate, it is fixed
Worm screw is rotatably connected in the plate face of plate, the both ends of worm screw have been connected through a screw thread upper locking nut and lower locking nut, locking
Tight nut and lower locking nut are fixedly connected with fixed plate respectively, and the end of wherein one end of worm screw is fixedly connected with handwheel, snail
The two sides at position are sequentially connected with one group of clamping device respectively among bar, two groups of clamping devices cooperations complete to file step up with
It unclamps；Every group of clamping device includes a worm gear, and worm gear is connect with worm-drive, and worm gear is rotatably connected in fixed plate, worm gear
Center be fixedly connected with swing rod, one end of swing rod is fixedly connected with worm gear, and the other end of swing rod is hinged with clamp arm, folder
One end of tight arm and swing rod are hinged, and the other end of clamp arm is fixedly connected with clamping plate, and the middle position of clamp arm is hinged with connecting rod,
One end of connecting rod and clamp arm are hinged, the other end of connecting rod with it is hinged with fixed plate.
The utility model by adopting the above technical scheme, takes file convenient, while thicker file easy to setup, together
When the folder that can be opened and closed not the larger strength of expense.
The technical solution of the utility model is described further with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
In figure: 1- fixed plate；2- worm screw；3- handwheel；4- worm gear；5- upper locking nut；6- lower locking nut；7- swing rod；
8- connecting rod；9- clamp arm；10- clamping plate；11- clamping device.
Specific embodiment
Embodiment is rotatably connected to worm screw in the plate face of fixed plate 1 as shown in Figure 1, a kind of folder, including fixed plate 1
2, the both ends of worm screw 2 have been connected through a screw thread upper locking nut 5 and lower locking nut 6, upper locking nut 5 and lower locking nut 6
It being fixedly connected respectively with fixed plate 1, the end of wherein one end of worm screw 2 is fixedly connected with handwheel 3, and the two of the intermediate position of worm screw 2
Side is sequentially connected with one group of clamping device 11 respectively, and two groups of cooperations of clamping devices 11 complete that file is stepped up and unclamped.
Every group of clamping device 11 includes a worm gear 4, and worm gear 4 and worm screw 2 are sequentially connected, and worm gear 4 is rotatably connected on fixation
On plate 1, the center of worm gear 4 is fixedly connected with swing rod 7, and one end of swing rod 7 is fixedly connected with worm gear 4, the other end of swing rod 7
It is hinged with clamp arm 9, one end of clamp arm 9 and swing rod 7 are hinged, and the other end of clamp arm 9 is fixedly connected with clamping plate 10, clamp arm
9 middle position is hinged with connecting rod 8, and one end of connecting rod 8 and clamp arm 9 are hinged, the other end of connecting rod 8 with it is hinged with fixed plate 1.
When work, handwheel 3 is rotated, drives worm gear 4 to rotate by worm screw 2, worm gear 4 drives swing rod 7 to swing, and swing rod 7 drives
Clamp arm 9 is moved to 2 direction of worm screw, clamps file by two clamping plates 10, worm screw 2 passes through upper locking nut 5 and lower locking screw
Mother 6 locks；Rotating backward handwheel 3 when unclamping file can be realized.
