A spring device is arranged between the swinging handle and the machine head, and the swinging handle can be replaced after swung upwards by the spring device. The device has the advantages of unhindered stroking and good working condition, and is favorable to improve the working life of equipment.
Description
Technical field
The utility model relates to a kind of braille typewriter frame head apparatus.
Background technology
At present, known portable braille typewriter, its typewriting mechanism is embedded in the typewriting pin on the interior bent plate, head walking when button is depressed, typewriting pin in being embedded in simultaneously on the bent plate is along with head impacts while walking tiltedly to slide to down, make the braille point be up to bigger than normal and round, and the pin of typewriting bends easily, cause the complete machine fluctuation of service.
Summary of the invention
The purpose of this utility model is to provide a kind of typewriter frame head apparatus that is used to print braille, and this device impacts smooth and easy, and operating mode is good, helps improving the working life of equipment.
The utility model is to constitute like this, comprising can be at the head of typewriter superior displacement, it is characterized in that: be provided with the one end and be articulated in the rocking handle that impacts on the head, impacting rocking handle below is provided with by its end that presses and is articulated on the head, the other end has the pendulum handle of shift fork mouth, be provided with the syringe needle that can slide up and down in the needle guard under the head, the male part of syringe needle through its top is set in the shift fork mouth of pendulum handle, stir work by the pendulum handle, be provided with between described pendulum handle and the head and make the spring assembly that pendulum resets on it.
During work, when pressing downwards when impacting rocking handle, impacting rocking handle rotates around its pin joint, pressing the pendulum handle simultaneously through its below makes the pendulum handle rotate around its pin joint, the pendulum handle presses the syringe needle of being located in its shift fork mouth downwards when rotating, make syringe needle along being located at needle guard under the head, thereby on the printing paper that is put under the head, impact out the braille concave point to lower slider.After having impacted, unclamp and impact rocking handle, the pendulum handle promptly put under the effect of spring assembly and is resetted, and through shift fork mouth drive syringe needle return.The utility model is because when impacting, the rotation that impacts rocking handle can be changed into vertically moving up and down of syringe needle, thereby than prior art, not only guaranteed the circularity standard of the braille concave point that impacts out, and make that to impact process more smooth and easy, improved impacting operating mode, thereby helped improving the working life of equipment.

The specific embodiment
The utility model embodiment comprises can be at the head 2 of typewriter 1 superior displacement, it is characterized in that: be provided with one end 3 and be articulated in and impact rocking handle 4 on the head, impacting rocking handle below is provided with by its end 5 that presses and is articulated on the head, the other end has the pendulum handle 7 of shift fork mouth 6, be provided with the syringe needle 9 that can slide up and down in the needle guard 8 under the head, the male part 10 of syringe needle through its top is set in the shift fork mouth of pendulum handle, stir work by the pendulum handle, be provided with between described pendulum handle and the head and make the spring assembly 11 that pendulum resets on it.
For once impact finish after, make head displacement in order to further work, above-mentioned head is located on the slide rail 12 of the typewriting body that slides in order to it, is provided with also on the head that its bottom 13 is articulated in the head bottom and by impacting the passive rocking handle 14 that rocking handle 4 presses; Described typewriting body is provided with the tooth bar 15 that parallels with slide rail, it is acute angle that described head is provided with its turning that is positioned at the tooth bar upside, bar 17 is turned for the swing of end, turning in its articulated section 16, swing is turned the bar lower end and is hinged with the clavula pawl 18 that can creep along tooth bar, be provided with reduction torsion spring between described little ratchet and its swivel pin 19, be provided with the slide block 21 that can slide up and down in the vertical conduit 20 at described head middle part, this slide block top is provided with in order to drive swing and turns the shifting block 23 of the cross bar 22 of bar, the slide block bottom is provided with and acts on passive rocking handle below so that by its projection that presses 24, be provided with spring reverse motion 25 between described slide block and the head; Perpendicular brace 26 bottoms, one extension spring 27 that bar is turned in described swing links with the head upper lateral part.
During work, when impacting rocking handle to lower swing, pressing passive rocking handle makes it to clockwise rotate around its pin joint, and passive rocking handle makes slide block to lower slider by the projection that presses the slide block of being located at its below, simultaneously the shifting block through slide block top drives swing and turns the cross bar of bar and make swing turn bar to clockwise rotate, at this moment, be articulated in little ratchet that swing turns the bar lower end and turn bar when clockwise rotating with swing at its pin joint, ratchet portion is subjected to the reaction force of tooth bar and overturns counterclockwise, thereby little ratchet is crossed a tooth of tooth bar and entered next tooth; Because swing is turned the perpendicular brace of bar and has been rotated certain angle, make the extension spring of being located between perpendicular brace bottom and the head upper lateral part stretch, under the tension spring tension effect, Nose Left moves, thereby has realized the displacement of head.
That the utility model not only impacts is smooth and easy, operating mode good, and the typewriting effect stability, and its popularizing application prospect is very considerable.
