The specific embodiment
In order to solve complex structure in existing linear transmission mechanism, to take up space greatly and the not enough problem of rigidity, only use the lifting frame in this utility model, the minimum parts such as underframe and drive motors have formed linear transmission mechanism, not only simplify the structure, saved the space, and effectively improved the rigidity problem.Describe drive mechanism of the present utility model in detail below in conjunction with accompanying drawing.
The first embodiment
Fig. 3 is the first example structure schematic diagram of the present utility model; Fig. 4 is the rise view of the first example structure of the present utility model; Fig. 5 is the first example structure top view of the present utility model; Fig. 6 is the partial enlarged drawing at A place in Fig. 4.
As shown in Figure 3, lifting frame 10 is the hollow type rectangular column, and the upper surface of lifting frame 10 and the bottom surface of examinating couch fix.Be provided with actuating arm 11 in the side of lifting frame 10, actuating arm 11 forms for plane protrusion on the sidewall of lifting frame 10, and vertical with leading screw 31, connect the lead screw hole 12 of actuating arm 11 and have externally threaded leading screw 31 screw threads sockets, described leading screw 31 can just/reverse turn under the driving of drive motors 40, and makes actuating arm 11 drive lifting frames 10 to move up and down.
In the situation that above-mentioned actuating arm 11 is thinner, leading screw 31 directly acts on the flank in lead screw hole 12, may cause stress surface less, destroys the problem of lead screw hole 12 female threads, has increased ut socket 13 in the present embodiment for this reason.Described ut socket 13 can consist of separately, and is fixed on actuating arm 11, also can be integrally formed with actuating arm 11.Here, for equipment is safeguarded and assembled, ut socket 13 is to be fixed on actuating arm 11 after forming separately.When ut socket 13 was set, lead screw hole 12 is interior can not arrange female thread.
In Fig. 3, Fig. 4 ut socket 13 be fixed in actuating arm 11 below, but also can be positioned at actuating arm 11 above, this thin and thick with actuating arm 11 is relevant, in the situation that actuating arm 11 is thinner, ut socket 13 is arranged on the top of actuating arm 11, can increase the lifting travel of lifting frame 10.
In order to limit the position of lifting frame 10, the lifting drive of examinating couch also comprises the underframe 20 that is " U " font, and the bottom surface of described underframe 20 is connected in base plate.Underframe 20 3 bread enclose lifting frame 10 in this utility model, and so both the good position of the lifting frame 10 of restriction, also reserved one side, the aspect maintenance in later stage.
For reduce lifting frame 10 in the process of lifting with the friction of underframe 20 inwalls, comprise two the first guide rails 21 at the inwall of underframe 20, in the part of lifting frame 10 corresponding described the first guide rails 21, the first sliding part 14 is set.As shown in Figure 6, it is one group that 15, two rollers of roller 15 can also be set on the first sliding part 14, bites the first guide rail 21 on underframe 20 inwalls.
In the lifting drive of the examinating couch of this embodiment, the height of drive motors 40 is lower, the length of leading screw 31 just can be longer, also just can increase the stroke up and down of lifting frame 10, but the size of general motor is fixed, it is very little that height can't be done, and in this utility model, drive motors 40 is to come rotational lead screw 31 by gear-box 30 for this reason.Described gear-box is the turbine and worm gear-box.
The second embodiment
Fig. 7 is the second example structure top view of the present utility model.
As shown in Figure 7, lifting frame 10 is the hollow type rectangular column, and the upper surface of lifting frame 10 and the bottom surface of examinating couch fix.Be provided with actuating arm 11 in the side of lifting frame 10, actuating arm 11 forms for plane protrusion on the sidewall of lifting frame 10, and vertical with leading screw 31, connect the lead screw hole 12 of actuating arm 11 and have externally threaded leading screw 31 screw threads sockets, described leading screw 31 can just/reverse turn under the driving of drive motors 40, and makes actuating arm 11 drive lifting frames 10 to move up and down.
In the situation that above-mentioned actuating arm 11 is thinner, leading screw 31 directly acts on the flank in lead screw hole 12, may cause stress surface less, destroys the problem of lead screw hole 12 female threads, has increased ut socket 13 in the present embodiment for this reason.Described ut socket 13 is plane near a upper side with frame, and is affixed on the side with frame, and actuating arm 11 is positioned on ut socket 13, and at this moment lead screw hole 12 is interior can not arrange female thread.
In order to limit the position of lifting frame 10, lifting frame 10 1 sides away from actuating arm 11 are provided with supporting walls 22, and the bottom surface of described supporting walls 22 is connected in base plate.
For reduce lifting frame 10 in the process of lifting with the friction of supporting walls 22, be provided with two the second guide rails 23 at supporting walls 22 near lifting frame 10 1 sides, in the part of lifting frame 10 corresponding described the second guide rails 23, the second sliding part 16 is set.It is one group that 15, two rollers of roller 15 can also be set on the second sliding part 16, bites the second guide rail 21 on underframe 20 inwalls.
Although this utility model discloses as above with preferred embodiment; so it is not to limit this utility model; any those skilled in the art; within not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
