Description
Technical field
The utility model relates to a kind of anti-skidding book car.
Background technology
Library's book car is exactly that library is used for transporting books and designing production, there is volume little (conveniently walking between bookshelf), the number of plies many (much more as much as possible filling books), both artistic and practical feature, general book height lower than and slightly go up position to human body waist, in order to adapt to the demand of transporting book, meet use habit.
Due in order to realize labour-saving effect, book car lower end is provided with roller structure, conveniently transport, but a same appearance drawback, when putting book, because the friction force on book car and ground is less, so easily generation relative sliding causes and puts book inconvenience.Authorization Notice No. is that disclosed one special library's transport battery-driven car of CN201287768Y discloses a solution, by arranging battery pack and motor, at DC motor electromagnetic brake case and by DC motor electromagnetic brake case realize make book car stop time being in transfixion state, but this technology keeps static by controlling machine shaft stall put book to realize control book car to facilitate under non-moving state, but this book car by driven by motor certainly will will increase the volume of itself and roller, take up room and add and promote lower thrust needed for slippage.So need a kind of structure simply and do not pass through the anti-skidding book car of one that design motor just can realize the braking of book car.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and can maintains static when placing books and can not increase the anti-skidding book car of one of its design volume.
For achieving the above object, the utility model provides following technical scheme: a kind of anti-skidding book car, comprise support and four rolling, described support comprises some frame plate groups for depositing books, frame plate group described in each has included two mutual vertically disposed frame plates, described support is installed with push-and-pull handle, and described support is provided with brake plate in roller place, and described brake plate is controlled by a stop button to extrude or to loosen described roller.By such setting, can by stop button by brake plate compress or loosen roller, when pinch rollers, brake plate stops roller to rotate the problem occurring putting book difficulty when preventing rotation, when loosening roller, ensure that by making roller normal rotation it normally can use when needs use, and play labour-saving effect.Described support offers cavity, cavity is provided with electromagnet, fixture block and described brake plate, and described brake plate is provided with the draw-in groove of a cooperation fixture block, when stop button is pressed, described in described electromagnetic actuation, fixture block is to draw-in groove, makes described brake plate keep the squeezed state with roller.By the setting of cavity, and electromagnet and fixture block are set at cavity, can make to play when book car is braked the effect keeping compressing, the stability of book car when improve braking.
The utility model can be set to further: described stop button is arranged at push-and-pull upper.Stop button is arranged on push-and-pull upper, more meets interactivity demand.
The utility model can be set to further: described fixture block is provided with the first inclined-plane, and described draw-in groove is equipped with the second inclined-plane, and when described fixture block is by adhesive, described first inclined-plane and the second inclined-plane conflict that brake plate is moved downward.By the setting on inclined-plane, can play an auxiliary stressed effect, make fixture block brake plate can be driven during adhesive to move downward, rational in infrastructure being easy to realizes.
The utility model can be set to further: described stop button is towards Bracket setting.Such setting, structure is simple, and stop button is not easily touched easily by mistake, and user hold push-and-pull time, finger is positioned at the position of stop button just, more meets interactivity demand.
The utility model can be set to further: described electromagnet is coupled to a braking circuit, described braking circuit comprises the braking contact and on-off element that are controlled by stop button, described electromagnet and described on-off element are arranged in same branch road, when the described braking closing of contact, it is electric that described switching elements conductive makes described electromagnet obtain.By on-off element, electromagnetism sheet iron strip is carried, simple and reasonable.
The utility model can be set to further: the controlled terminal of described switching valve is coupled with a light-emitting diode, and when switching valve conducting, described light-emitting diode obtains electric work, by such setting, can play the effect that a band carries.
By adopting technique scheme, compared to existing technology, following effect can be played: by stop button by brake plate compress or loosen roller, when pinch rollers, brake plate stops roller to rotate the problem occurring putting book difficulty when preventing rotation, when loosening roller, ensure that by making roller normal rotation it normally can use when needs use, and retains the effect of original laborsaving push-and-pull.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
Shown in seeing figures.1.and.2, a kind of anti-skidding book car, comprise support 300 and four rolling 100, described support 300 comprises some frame plate groups 310 for depositing books, frame plate group 310 described in each has included two mutual vertically disposed frame plates, described support 300 is installed with push-and-pull 320, and described support 300 is provided with brake plate 210 in roller 100 place, and described brake plate 210 is controlled by a stop button 321 to extrude or to loosen described roller 100.Described stop button 321 is arranged at push-and-pull on 320.With reference to shown in Fig. 3 and Fig. 4, described support 300 offers cavity, cavity is provided with electromagnet 212, fixture block 213 and described brake plate 210, described brake plate 210 is provided with the draw-in groove 215 of a cooperation fixture block 213, when stop button 321 is pressed, fixture block 213 to draw-in groove 215 described in the adhesive of described electromagnet 212, described brake plate 210 is made to keep the squeezed state with roller 100, brake plate is connected to prevent brake plate state of nature from being because of Gravitational sliding with support 300 by the first spring, make the draw-in groove 215 of brake plate can coordinate with fixture block 213 simultaneously, fixture block 213 is connected with the second spring 214.Described fixture block 213 is provided with the first inclined-plane, and described draw-in groove 215 is equipped with the second inclined-plane, and when described fixture block 213 is by adhesive, described first inclined-plane and the second inclined-plane conflict that brake plate 210 is moved downward.Described stop button 321 is arranged towards support 300.Described electromagnet 212 is coupled to a braking circuit, described braking circuit comprises the braking contact SW and on-off element that are controlled by stop button 321, described electromagnet 212 is arranged in same branch road with described on-off element, when described braking contact SW closes, described switching elements conductive makes described electromagnet 212 obtain electric.The controlled terminal of described switching valve Q1 is coupled with a LED 1, and when switching valve Q1 conducting, described LED 1 obtains electric work.With reference to shown in Fig. 5, when stop button 321 is pressed, the anode of LED 1 is set to high level, NPN aerotron produces pipe fall, aerotron is made to meet turn-on condition, and the time delay circuit of C1 and R1 composition can of short duration time delay, delay time is predeterminable is one second, that is, when braking contact SW and being released, after one second, electromagnet 212 must be electric in time delay, adhesive fixture block 213, make brake plate 210 be moved downward to pinch rollers 100, ensure its state, using state is reminded in LED 1 luminescence simultaneously.Principle is simply easy to realize.
