Description
Technical field
This utility model relates to a kind of sick bed braking mechanism, refers in particular to a kind of sick bed and presses commentaries on classics lifting braking mechanism.
Background technology
Usually, roller is installed all on the cabinet base of sick bed, makes things convenient for moving of sick bed itself on the one hand, move sufferer when more convenient on the other hand sufferer lies on the sick bed.Move in the process, need accomplish light, slow motion as far as possible, sufferer is lain on the sick bed imperturbably, unlikely mobile generation with sick bed is rocked and uncomfortable sensation is arranged.But, move in the process and still can control gait of march by the size of control thrust (or pulling force), make sufferer feel steady, comfortable, in case move when stopping, possible nobody buttresses sick bed again, sick bed just is in a kind of free state, once there being external force collision arbitrarily to move, even not having external force on the slope and do the time spent and can arbitrarily move yet, make sufferer be in turbulent among, therefore, existing sick bed can be installed brake gear at cabinet base roller place.Really keep resting state when this brake gear can make sick bed stop to advance, avoid moving freely and bring sense of discomfort to sufferer.
Yet, existing brake gear is locked or during release in each brake, all needing jackknifes pulls brake handle with hands, operate very inconvenient, particularly when the brake of acclive place, original control sick bed does not move has required great effort, and the operation brake that also will jackknife is extremely difficult especially, and a common people is difficult to operation.
Therefore, a kind of real being necessary of brake gear of handled easily be provided.
The utility model content
At the problems referred to above, this utility model provides a kind of sick bed to press changes the lifting braking mechanism, makes the sick bed brake convenient, fast.
To achieve these goals, the technical solution of the utility model is as follows:
Sick bed press to change the lifting braking mechanism, comprise pedestal, pedal and by cylinder, on change part, change the pressure commentaries on classics lifting assembly of the similar ball pen that part, back-moving spring form down; Pedestal is installed on the cabinet base and is used to install roller; Cylinder is installed on the pedestal, and the top of cylinder and bottom all have perforation, also forms axial sliver on the inwall of cylinder, and the lower end of sliver forms helical teeth; Last commentaries on classics part, change part and back-moving spring down and be assembled in the cylinder; The top of last commentaries on classics part forms stick and below formation pressure tooth, and stick is stretched out by the perforation at cylinder top; The outer wall that changes part down forms the fin cooperate with the sliver of cylinder and below formation push rod, the top of fin then forms the helical teeth that cooperates with the pressure tooth of the helical teeth of cylinder and last commentaries on classics part, push rod is stretched out by the perforation of cylinder bottom, and the extended position of push rod when brake is lower than idler wheel bottom and is higher than idler wheel bottom at the extended position of separating in a flash; The back-moving spring that the commentaries on classics part upwards resets under the order is installed in down to be changeed between part and the cylinder; The pedal that is used to push stick is installed in pedestal; Change part and change part down by pressing by pedal, and cooperate the location and realize brake or remove the location cooperating and realizing un-brake by the helical teeth of helical teeth that changes part down and cylinder to the descending pen core lifting action of making similar ball pen.
Described cylinder is fastened by top cylinder and doffing and forms, and the top of top cylinder and the bottom of doffing all have perforation, form axial sliver on the inwall of top cylinder.
Form the pivot seat on the described pedestal, pedal is hubbed on the pivot seat by rotating shaft, increases a briquetting between stick and the pedal, forms chute on the briquetting, the top sidepiece of stick forms the slide block that cooperates with chute, and briquetting is connected with pedal by rotating shaft and is rotated by pedal control.
After adopting such scheme, when this utility model uses, if desire brake, just step on pedal downwards with foot, cooperate by pressing the commentaries on classics part and changeing part down by sliver and fin to descending, pressing changes the pen core down maneuver that lifting assembly is made similar ball pen, when the pressure tooth of last commentaries on classics part is lower than the helical teeth of cylinder with the demarcation line of changeing the helical teeth of part down, change part promptly under the effect of back-moving spring, to deflect down and cooperate the location with the helical teeth of cylinder, make push rod remain on this position, this moment, the minimum extended position of push rod was lower than idler wheel bottom, pedestal and be installed in roller on the pedestal etc. and held up together, roller does not contact with ground, reaches the purpose of brake.
If desire un-brake, the reuse foot is stepped on pedal downwards, change part and change part to descending down by pressing, when the pressure tooth of last commentaries on classics part is lower than the helical teeth of cylinder with the demarcation line of changeing the helical teeth of part down, changeing part down promptly deflects under the effect of back-moving spring, sliver and fin cooperate again, pressing changes the pen core vertical motion that lifting assembly is made similar ball pen, push rod is upwards resetted, this moment, the minimum extended position of push rod was higher than idler wheel bottom, pedestal and be installed in roller on the pedestal etc. and fall relatively together, roller contacts with ground again, reaches the purpose of un-brake.
This shows that brake of the present utility model and un-brake are operated all only using foot one and stepped on pedal and can finish, so easy to operate, quick.
Below in conjunction with the drawings and specific embodiments this utility model is described further.
