The supporting leg mechanism comprises a concave frame 7, two groups of supporting bars 8, two groups of supports 9 and two groups of arc plates 10, wherein the supports 9 penetrate through the long opening 3, can move along the arc opening 4 and can be clamped into the bayonet 5; wherein, the concave frame 7 is fixed at the bottom side of the front part of the bed body 1, two groups of third gears 27 which are symmetrical and meshed with each other are respectively connected in the concave frame 7 in a rotating way through a rotating shaft, and the top ends of the rotating shafts are both fixed with the branch bars 8, so that the two groups of branch bars 8 realize synchronous rotation with opposite rotation directions.

A switching mouth 22 has all been seted up to the 8 free ends of branch, is fixed with first pinion 11 in the switching

mouth

22, and 9 bottoms of support are rotated with first pinion 11 respectively and are connected, and the support 9 other end is rotated and is connected with connecting piece 12, and connecting piece 12 passes through the chain drive cooperation with first pinion 11.

Specifically, the bottom end of the support 9 is rotatably connected with a second gear shaft 23 meshed with the first gear shaft 11, the two ends of the support 9 are further rotatably connected with third gear shafts 24, the two groups of third gear shafts 24 are matched through chain transmission, one group of third gear shafts 24 is meshed with the second gear shaft 23, the other group of third gear shafts 24 is fixedly connected with the connecting piece 12, and the two groups of arc plates 10 are respectively fixed at the top of the connecting piece 12.

Wherein, the teeth of the second tooth shaft 23 are symmetrically arranged at two sides of the shaft rod, and the teeth of the second tooth shaft 23 can be respectively engaged with the teeth of the first tooth shaft 11 and the teeth of the third tooth shaft 24 arranged at the bottom end of the bracket 9, so that through the transmission fit of the second tooth shaft 23, when the bracket 9 rotates relative to the first tooth shaft 11, the third tooth shaft 24 arranged at the bottom end of the bracket 9 rotates, and the second tooth shaft 23 is also used for changing direction, namely, the direction of the third tooth shaft 24 is opposite to the direction of the bracket 9.

As shown in fig. 1 or 8, at this time, the leg support mechanism is in an unfolded state, two sets of supports 9 are moved out from the bayonet 5, one set of support 9 is moved towards the long opening 3 along the arc opening 4, at this time, through the cooperation of the two sets of third gears 27, the other set of support 9 is moved towards the long opening 3 along the arc opening 4, then the supports 9 are respectively rotated backwards, through the toothed chain transmission cooperation, the connecting piece 12 is rotated towards the front side of the support 9, then the arc plate 10 is rotated towards the front side of the support 9, so that the arc plate 10 can be folded and folded to the top side of the bed body 1, and the two sets of arc plates 10 form an arch structure.

For guaranteeing that two sets of arc boards 10 after folding receipts to the 1 top side of the bed body are symmetrical each other and just not crooked, set up two sets of being used for the spacing third spacing grooves 20 of two sets of arc boards 10 after folding at the 1 top side of the bed body, through third spacing groove 20, it is spacing to carry on to the arc board 10 front and back tip of folding receipts to the 1 top side of the bed body, guarantees that two sets of arc boards 10 are symmetrical each other and just not crooked, and then improves the abdominal comfort level of propping up the patient.

When the landing leg mechanism demonstrates, earlier respectively with support 9 outwards rotation, arc plate 10 rotated to the rear side of support 9 respectively this moment to after support 9 rotated to long mouthful 3 and arc mouth 4 junction, remove to bayonet 5 direction along arc mouth 4 again, through the restriction of arc mouth 4 this moment, make arc plate 10 and support 9 keep relatively fixed, later with in the bayonet 5 of support 9 card income again, thereby realize support 9 fixed.

In order to prevent the legs of the patient from sliding off the unfolded arc plate 10 when the lithotomy position is performed, magic tape binding bands 21 are fixedly connected to the arc plate 10 and used for binding the legs of the patient on the arc plate 10; meanwhile, sponge cushions 28 are arranged on the arc plates 10, so that the comfort of the patient is improved.

For avoiding when expanding, two sets of arc plates 10's mutual interference causes support 9 can't follow the removal of 4 directions in the radial gap, connecting piece 12 includes cup 1201, spring 1202, ring lid 1203 and branch pipe 1204, cup 1201 lateral wall symmetry fixedly connected with stabilizer blade 1205, the third pinion 24 of keeping away from a 8 one end of branch is fixed between two sets of stabilizer blades 1205, be provided with latch ring 1206 in the cup 1201, ring lid 1203 coaxial fixed connection is on cup 1201, branch pipe 1204 one end is provided with can with the second gear 1207 of latch ring 1206 meshing, branch pipe 1204 passes and wears out ring lid 1203, the branch pipe 1204 other end is provided with the mounting disc 1208 with arc plates 10 fixed connection, spring 1202 sets up between second gear 1207 and cup 1201 inslot wall.

Wherein, the installation of the branch pipe 1204 and the spring 1202 is facilitated by the arrangement of the ring cover 1203; meanwhile, through the spring 1202, when no weight is pressed on the arc plate 10, the second gear 1207 is ejected out of the latch ring 1206, so that the branch pipe 1204 can rotate relative to the cup groove 1201, and then the arc plate 10 rotates relative to the cup groove 1201, and then after the two sets of arc plates 10 are contacted with each other, the two sets of arc plates 10 can rotate relative to the branch pipe 1204, so that the problem that the support 9 cannot move along the direction of the arc opening 4 due to mutual interference of the two sets of arc plates 10 is avoided.

When the leg portion presses on the arc plate 10 or the abdomen portion presses on the arc plate 10, the second gear 1207 is clamped into the latch ring 1206, so that the branch pipe 1204 and the cup slot 1201 are fixed relatively, that is, the arc plate 10 and the cup slot 1201 are fixed.

Meanwhile, when the supporting leg mechanism is displayed, the arc plate 10 can be rotated relative to the cup groove 1201, the horizontal angle between the arc plate 10 and the support 9 can be adjusted, and the supporting leg mechanism is further suitable for different patients.

In order to effectively ensure the elasticity of the spring 1202, a limiting pipe 1209 for limiting the second gear 1207 is coaxially arranged in the cup groove 1201; the spring 1202 is sleeved outside the limiting pipe 1209, so that the limiting pipe 1209 limits the second gear 1207, the second gear 1207 is prevented from being excessively downward, and the spring 1202 is kept in a normal elastic range.

Two sets of arm boards 13 symmetry rotate in bed body 1 left and right sides, and two sets of arm boards 13 and leg board 2 linkage cooperation, wherein, this technical scheme still including be used for arm board 13 and leg board 2 spacing locating part 6.
