Description
Technical field
The utility model relates to a kind of hold down gag, is specifically related to a kind of hand-rail type hold down gag.
Background technology
In office field, usually need to use press fit device, in library or bookstore, usually there are books too much the curling phenomenon of page to occur because browsing, the books that these pages are curling need to carry out smooth rectification with press fit device.In electrical equipment is produced, usually need to use press fit device to carry out smooth rectification to the circuit board that warpage occurs.But existing hold down gag is applied to the professional production such as machinery, electromechanics field more, the kind of drive also more relates to electric, hydraulic mechanism, is not suitable for for life office or household field.
Utility model content
For above problem, the purpose of this utility model is to provide a kind of hand-rail type hold down gag, and it is simple in structure, easy to operate, and safety and sanitation can process at electronic devices and components completely, use safely in the occasion such as routine office work.
For reaching above object, the utility model is achieved by the following technical solutions.
A kind of hand-rail type hold down gag, is characterized in that, comprises cylindrical shell, be arranged on the side door on cylindrical shell, be separately fixed at cog plate and lower bottom base in cylindrical shell, be arranged on the crank shaft of the plate central authorities that cog, be fixedly set in the master gear on crank shaft; Described lower bottom base and cog and be provided with two leading screws free to rotate between plate; The upper gap of described two leading screws runs through after the plate that cogs the center of the pinion corresponding with two respectively and is fixedly connected with; Described two pinions engage with described master gear simultaneously; Lower bottom base and cog and be also provided with a movable platform between plate, described movable platform offers two screwed holes, and two screwed holes coordinate with two corresponding threads of lead screw; On respect to one another of movable platform and lower bottom base, be fixed with respectively a pressing platform; The described plate top that cogs is also provided with a upper end cover, and described crank shaft runs through upper end cover and is fixedly connected with a rocking handle.
The feature of technique scheme and further improvement:
Described lower bottom base, cog plate and movable platform be arranged in parallel.
Described master gear is positioned in the middle of two pinions, and the radius of master gear is greater than the radius of pinion.
Described lower bottom base is provided with two blind holes, is provided with thrust bearing in blind hole, and the lower end of two leading screws coordinates with thrust bearing.
The beneficial effects of the utility model are, drive two leading screw rotations by rotation crank swing pinion, two leading screws of rotation make with it the movable platform of threaded engagement simultaneously move up and down along leading screw, in the time that movable platform moves down, movable platform and two relative pressing platform pressings gradually on lower bottom base also have the self-locking performance of leading screw after pressing.Hold down gag of the present utility model is reliability and durability, is not suitable for electric, hydraulic mechanism, clean hygiene.
Accompanying drawing explanation
Below by the drawings and specific embodiments, the utility model is further detailed:
Fig. 1 is that hand-rail type hold down gag of the present utility model removes the structural representation after cylindrical shell and upper end cover;
Fig. 2 is that Fig. 1 loads onto the profile schematic diagram after cylindrical shell and upper end cover.
In above figure: 1, cylindrical shell; 2, upper end cover; 3, side door; 4, rocking handle; 5, crank shaft; 6, the plate that cogs; 7, master gear; 8, pinion; 9, leading screw; 10, movable platform; 11, lower bottom base; 12, pressing platform.
The specific embodiment
With reference to figure 1 and Fig. 2, a kind of hand-rail type hold down gag of the present utility model, it has cylindrical shell (1), on cylindrical shell (1), be provided with side door (3), in cylindrical shell (1), be fixed with respectively the plate that cogs (6) and lower bottom base (11), at the plate that cogs (6), central authorities are provided with crank shaft (5), at the upper fixed cover of crank shaft (5), master gear (7) are housed.Between lower bottom base (11) and the plate that cogs (6), be provided with two leading screws free to rotate (9).The upper gap of two leading screws (9) runs through after the plate that cogs (6) center of the pinion (8) corresponding with two respectively and is fixedly connected with.Two pinions (8) engage with master gear (7) simultaneously.Between lower bottom base (11) and the plate that cogs (6), be also provided with a movable platform (10), in movable platform (10), offer two screwed holes, two screwed holes and corresponding two leading screws (9) threaded engagement.On respect to one another of movable platform (10) and lower bottom base (11), be fixed with respectively a pressing platform (12).Cog plate (6) top is also provided with a upper end cover (2), and crank shaft is fixedly connected with a rocking handle (4) through upper end cover (2).
When rotation crank (4), rocking handle drives master gear (7) rotation, and master gear (7) drives again two pinions (8) to drive synchronize with two pinions (8) respectively two leading screws (9) rotating Vortex of connection.Due to movable platform (10) and two leading screws (9) threaded engagement, so movable platform (10) will move up or down according to the sense of rotation of two leading screws.Can or unclamp by the pressing of the direction of rotation control hold down gag of the present utility model of rocking handle.
