Description
Technical field
This utility model relates to a kind of lumbar traction bed, particularly relate to a kind of can from the loin drawing device of main regulation.
Background technology
Lumbar traction bed is by implementing the pull strength parallel with vertebra to prolapse of lumbar intervertebral disc patient body, and slow micro-stretching patient body alleviates ailing a kind of device, this device is generally grouped into by support section and power transmission part, support section supports user to lie low or the vertical mechanism sat, and motivation transfer motion part is the part producing pull strength.
Notification number be CN2776348Y patent discloses a kind of loin drawing device, by rotary screw, two boards is promoted to realize traction round about during this traction apparatus work, owing to being that two screw rods share a screw thread pair, when therefore two screw rods are installed, centering requires high.In addition, larger torque need be adopted to carry out rotary screw when this traction apparatus uses, and need rotate many turns guiding piece just can be made to move to desired location, it is not too convenient therefore to use.
Summary of the invention
The purpose of this utility model is to provide a kind of installation, lumbar traction bed easy to use.
For achieving the above object, the solution that this utility model adopts is: a kind of lumbar traction bed, comprise bedstead, bed board and belt pulling buckle, described bed board totally two, two bed boards are respectively equipped with belt pulling buckle, bedstead is also provided with gripper shoe, and four guide rails, along its length in the symmetrical gripper shoe be arranged on bedstead, each guide rail are provided with slidably movable block; Screw mandrel is arranged on the middle part of bedstead in the width direction, which is provided with the screw thread pair be mated, one end and the screw thread pair of connecting rod are hinged, and the crossbeam of the other end and homonymy is hinged, crossbeam is fixedly connected with two movable blocks of homonymy simultaneously, and bed board to be positioned on movable block and to be fixedly connected with movable block; One end of screw mandrel is provided with handwheel, and the other end is provided with the locking system stoping screw mandrel reversion.
Above-mentioned locking system comprises handle, ratchet and elastic steel sheet, ratchet is fixedly mounted on the other end of screw mandrel, and handle on bedstead, which is provided with ratchet by Stud connection, elastic steel sheet is arranged on bedstead, and is tight against and outside handle, the ratchet on ratchet is engaged with the ratchet on handle.
This utility model has following effect:
(1) by adopting four-bar mechanism to transmit power, not only power transmission route is far away, and structure is simple;
(2) only have a screw mandrel, there is not centering problem, convenient for installation and maintenance;
(3) handwheel is arranged on bedside, and user is easy to operate.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is the enlarged drawing of the A direction view of Fig. 1.
In figure: 1-bed board, 2-handle, 3-ratchet, 4-movable block, 5-screw mandrel, 6-screw thread pair, 7-connecting rod, 8-crossbeam, 9-bedstead, 10-guide rail, 11-gripper shoe, 12-handwheel, 13-elastic steel sheet
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, this utility model is described in further detail.
Embodiment
As shown in Figure 1 and Figure 2, this utility model comprises bed board 1, handle 2, ratchet 3, movable block 4, screw mandrel 5, screw thread pair 6, connecting rod 7, crossbeam 8, bedstead 9, guide rail 10, gripper shoe 11, handwheel 12 and elastic steel sheet 13, bed board 1 totally two, two bed boards 1 are respectively equipped with belt pulling buckle.Gripper shoe 11 totally four, four gripper shoe 11 bolt spacings are fixed on bedstead 9.Totally four, guide rail 10, four guide rail 10 soket head cap screws are fixed in gripper shoe 11, and four guide rails 10 are arranged symmetrically on bedstead 9.Each guide rail 10 is also provided with movable block 4, and movable block 4 can slide along guide rail 10.Screw mandrel 5 is arranged on the middle part of bedstead 9 in the width direction, one end of screw mandrel 5 is provided with handwheel 12, the other end is provided with the locking system stoping screw mandrel reversion, screw mandrel 5 is also provided with the screw thread pair 6 be mated, one end and the screw thread pair 6 of connecting rod 7 are hinged, the crossbeam 8 of the other end and homonymy is hinged, and crossbeam 8 is fixedly connected with two movable blocks 4 of homonymy simultaneously, and four connecting rods 7 form four-bar mechanism and promote crossbeam 8 and produce pull strength.Bed board 1 is positioned on movable block 4, and is connected with soket head cap screw with movable block 4.In order to avoid crossbeam 8 and screw mandrel 5 bump against, be also provided with cross bar at crossbeam 8 in the face of screw mandrel 5 side.
The locking system adopted in the present embodiment comprises handle 2, ratchet 3 and elastic steel sheet 13, ratchet 3 is fixedly mounted on the other end of screw mandrel 5, handle 2 by Stud connection on bedstead 9, which is provided with ratchet, elastic steel sheet 13 is arranged on bedstead 9, and is tight against in the outside of handle 2 and the ratchet on ratchet 3 is engaged with the ratchet on handle 2.
When user uses this utility model, first lie on bed board 1, sash pulling buckle, then rotation hand wheel 12, now screw mandrel 5 rotation forces screw thread pair 6 moves, and crossbeam 8 moves to two ends and promotes movable block 4 and moves under the effect of four-bar mechanism, and bed board 1 also moves thereupon.After moving into place, ratchet 3 pins screw mandrel 5 and pull strength is kept, and after finishing using, lifts handle 2, outside compression elasticity steel disc 13, and ratchet is separated with ratchet, and bed board 1 gets back to initial position with movable block 4.
The foregoing is only one of this utility model preferred embodiment, it is pointed out that to those of ordinary skill in the art under the prerequisite not departing from this utility model use principle, some modification and improvement can also be done, also should be considered as this utility model protection domain.
