Abstract
The utility model relates to a portable operating table of mesa, including the bedstead seat, can with the movable support of bedstead seat relative movement, the rack is fixed on the bedstead seat, is equipped with a transmission shaft on movable support, is fixed with a worm in the one end of transmission shaft, and the other end is fixed with a crank, is equipped with the helical gear with worm engaged with, and helical gear meshes with the rack mutually, its simple structure, and worm transmission has from the locking performance, guarantees the stationary state of operation mesa under the condition of not shaking, and transmission process is steady.
Description
One, technical field
This utility model relates to operating-table, particularly operation table with movable table top.
Two, background technology
Operation relatives of Taiwan compatriots living on the Mainland medical device product is implemented operations such as surgery such as head, neck, splanchnocoel, perineum and extremity and department of obstetrics and gynecology, department of eye, orthopaedics for hospital operating room.The table top translation functions can be in operation process and the supporting use of C type arm, and all tools all are motor-driven operating tables with the operating-table of table top translation functions, and by the motor transmission, cost is big, the price height.Patent 03232554 discloses " a kind of parallel-moving type operation table ", be provided with a screw mandrel in the inside of the external cover of bed, one end of screw mandrel connects first gear, first gear and second gears engaged, second gear is connected with handle, the other end of screw mandrel and swivel nut one end socket, the swivel nut other end is fixedlyed connected with a guide rail, and the teeth angle of first gear and second gear is designed to 45 degree.Make gear rotation by shaking handle, allow screw mandrel and swivel nut relative motion, and transfer rectilinear motion to.Its complex structure, the transmission chain length can not realize quick translation.
Three, summary of the invention
The purpose of this utility model is at above-mentioned the problems of the prior art, and a kind of operation table with movable table top is provided.
The purpose of this utility model is to realize like this, a kind of operation table with movable table top, comprise the bedstead seat, the travel(l)ing rest that can relatively move with the bedstead seat, tooth bar is fixed on the bedstead seat, is provided with a power transmission shaft on travel(l)ing rest, end at power transmission shaft is fixed with a worm screw, the other end is fixed with a crank, is provided with the helical gear that is meshed with worm screw, and the helical teeth wheel and rack is meshed.
The translation that the beneficial effects of the utility model travel(l)ing rest drives the operating-table table top is to drive the worm screw rotation by crank, worm screw and helical gear engagement, and helical gear and helical rack engagement, the tooth bar moving linearly drives the bed surface translation, and it is simple in structure; Worm-drive has self-locking property, guarantees at the stationary state that does not shake operation table top under the situation; Helical gear and helical rack transmission guarantee the stationarity in the transmission process.
Four, description of drawings
Fig. 1 is this utility model structure diagram.
Among the figure: 1 crank, 2 power transmission shafts, 3 tooth bars, 4 bedstead seats, 5 helical gears, 6 worm screws, 7 travel(l)ing rests
Five, the specific embodiment
Below in conjunction with accompanying drawing, this utility model specific embodiment is described in further detail:
A kind of operation table with movable table top among Fig. 1, one power transmission shaft 2 is arranged on the travel(l)ing rest 7, one end is fixed with a crank 1, crank 1 rotates can realize that bed surface moves, the other end at power transmission shaft 2 is fixed with a worm screw 6, worm screw 6 is meshed with helical gear 5, helical gear 5 matches with tooth bar 3, tooth bar 3 is fixed on bedstead seat 4 tops, travel(l)ing rest 7 moves by rotating crank 1 relative to bedstead seat 4 and realizes by power transmission shaft 2, worm screw 6, helical gear 5 and tooth bar 3, worm-drive has auto-lock function, makes travel(l)ing rest 6 relative bedstead seat 7 relative motioies.
