Description of drawings
Fig. 1 is the structural representation of the interlock rollover mechanism of this utility model nursing bed.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the embodiment of the interlock of nursing bed of the present utility model rollover mechanism is elaborated.
With reference to figure 1, this utility model provides a kind of rollover mechanism of nursing bed, comprising: left and right two cover interlock laterally turning-over devices, bed board, bedstead 7 and control device (not shown).
Described left and right two cover interlock laterally turning-over devices are symmetricly set on the bed board below, and described bed board is connected with bedstead 7, and described control device is connected with left and right two cover interlock laterally turning-over devices respectively.
Described bed board comprises back of the body left plate 4, back of the body right plate 5, back of the body central panel 6 and back of the body central panel holder 3, and an end of an end of described back of the body left plate 4 and back of the body right plate 5 adopts hinged mode to be connected with described back of the body central panel 6 respectively; Back of the body central panel holder 3 is arranged on the bottom central authorities of back of the body central panel 6, and this back of the body central panel holder 3 is welded on the bedstead 7, is supporting back of the body central panel 6.
Every cover laterally turning-over device includes rollover side link 1, rollover roller 2 and linear push rod 4; Described rollover side link 1 is arranged on the below of back of the body left plate 4 or back of the body right plate 5, above-mentioned rollover side link 1 is made of straight line pole and tripod, described tripod position is in an end of straight line pole, and a limit of this tripod overlaps with straight line pole, one summit of this tripod overlaps with the end points of straight line pole, one end and the bedstead 7 of described straight line pole are hinged, and the pin joint 8 of above-mentioned straight line pole and bedstead 7 is near the below of back of the body central panel 6; One end of described linear push rod 4 is welded on the bedstead 7, and its other end is hinged with the tripod of rollover side link 1; Described rollover roller 2 is arranged on the bottom of back of the body left plate 4 or back of the body right plate 5, rolls and connect in the top of the rollover side link 1 that above-mentioned rollover roller 2 is corresponding with it, and back of the body left plate 4 or back of the body right plate 5 are rotated around its pin joint with back of the body central panel 6.
When the linear push rod of the laterally turning-over device that promotes the left side, the rollover side link hinged with linear push rod rotates counterclockwise around bedstead, the rollover roller rolls along the upper surface of rollover side link, makes the back of the body left plate that links to each other with the rollover roller begin to rotate counterclockwise around the pin joint of back of the body left plate with back of the body central panel.Similarly, when the linear push rod of the laterally turning-over device that promotes the right side, the rollover side link hinged with linear push rod clockwise rotates around bedstead, the rollover roller rolls along the upper surface of rollover side link, makes the back of the body right plate that links to each other with the rollover roller begin to clockwise rotate around the pin joint of back of the body right plate with back of the body central panel.
When the back of the body left plate rotational angle greater than the back of the body right plate rotational angle the time, can realize the left side turn over, promptly the rollover to the right; And, can realize that the right side turns over when the rotational angle of back of the body right plate during greater than the rotational angle of back of the body left plate, i.e. rollover is left.In a specific embodiment, described about two cover interlock laterally turning-over devices when overturning, the rotational angle of back of the body left plate be greater than 20 ° and smaller or equal to 70 °, the rotational angle of back of the body right plate be smaller or equal to 20 °, thereby turns on the left of the realization.
Wherein, for making upset comparatively steadily and that bed board is subjected to is heavy average, the both sides son that rolls can be installed on the middle part of back of the body left plate and back of the body right plate respectively, and its mounting means can be welding, riveted joint or hinged.
Described control device can adopt single-chip microcomputer and remote control unit, and described remote control unit can be keyboard, mobile phone/PDA etc. can carry out mutual equipment with single-chip microcomputer.
In a specific embodiment, when the needs of patients on being positioned at described nursing bed was turned on one's side, to the single-chip microcomputer transfer instruction, single-chip microcomputer sent the running instruction to linear push rod then by keyboard button, make its motor enter duty, the both sides bed board is rotated together.When needs carry out the right side when turning over, when the left side bed board is turned to certain angle, stop its linear push rod is sent the running signaling by single-chip microcomputer earlier, bed board stop motion on the left of making, and the right side bed board can continue to overturn, thereby the rollover angle that makes the right side bed board is greater than the left side bed board, and turn on the realization right side; Similarly, when needs carry out the left side when turning over, when the right side bed board is turned to certain angle, stop its linear push rod is sent the running signaling by single-chip microcomputer earlier, make right side bed board stop motion, and the left side bed board can continue to overturn, thereby the rollover angle that makes the left side bed board is turned on the left of realizing greater than the right side bed board;
Compared to prior art, the utlity model has following advantage:
(1) changed deficiency on the rollover mechanism design of existing nursing bed, realized nursing bed can carry out safe about the rollover motion, make bed person under the state of prone position, realize freely standing up, and health does not have sideslip.
(2) change the complexity of existing mechanism, alleviated the complexity of assembling, improved the stability of rollover motion.
(3) rollover mechanism by with electric-linked mode, reduced the complexity of mechanism, alleviated the weight of whole bed, reduced production cost.
(4) replaced servomotor with linear push rod, used plane hinge mechanism, and drive mechanism, frame, bed board framework etc. adopt metal material and composite manufacturing, hinged selection standard spare screw bolt and nut, greatly reduce production cost, helped the popularization and the industrialization production of product.
Drive mechanism of the present utility model, bedstead, bed board framework adopt metal material and/or composite manufacturing, the hinged standard component such as screw bolt and nut of selecting for use, and technology is easy, is beneficial to the popularization and the large-scale production of product.
Though this utility model by the preferred embodiment explanation as above, these preferred embodiments are not in order to limit this utility model.Those skilled in the art in not breaking away from spirit and scope of the present utility model, should have the ability various corrections and additional are made in this preferred embodiment, and therefore, protection domain of the present utility model is as the criterion with the scope of claims.
