Abstract
The utility model discloses a sickbed with hand crack lifting-operating mechanism, comprising a back bed surface and a thigh bed surface whose undersides are equipped with lifting supports. One end of the bed head is equipped with a crank which is connected into integration with a propeller shaft connecting with a connecting rod at the lower side of the bed surface, the lower side of the other end of the bed surface is equipped with a screw thread rod corresponding to the connecting rod and the screw thread rod is sheathed with a sheath. The utility model is characterized in that the lifting supports under the back bed surface and the thigh bed surface are respectively movably connected with the sheath and the connecting rod via hinges; the propeller shaft is equipped on the bed head via a bearing support, and an automatic trip is equipped between the both ends of the propeller shaft near to the position of the bearing support. The utility model has the advantages of flexible lifting of the bed surface, labor saving, comparatively strong carrying capacity of the propeller shaft, firm integral structure and long service life and the bed surface is not easy to thrust broken by the fractured support frames.
Description
Technical field this utility model belongs to hospital ward sick bed technical field, relates to a kind of sick bed that is provided with band hand crank lifting operating mechanism at the head of a bed.
The background technology prior art is provided with the sick bed of band hand crank lifting operating mechanism, comprises back bed surface and the shank bed surface of dividing into lifting support; One end of the head of a bed is provided with the crank that the power transmission shaft that is connected with connecting rod below the bed surface is connected as a single entity, and is provided with the screw thread ratch corresponding with connecting rod, suit sheath on the screw thread ratch below the other end bed surface; Lifting support below said back bed surface and the shank bed surface respectively with sheath and connecting rod for fixedlying connected.The sick bed of this structure, the lifting of back bed surface and shank bed surface axially moves by power transmission shaft drivening rod and sheath entirely and makes lifting support below back bed surface and the shank bed surface support the lifting of back bed surface and shank bed surface.Therefore, the power transmission shaft axially loaded is excessive, influences its service life; In addition, the lifting support below back bed surface and the shank bed surface respectively with sheath and connecting rod for fixedlying connected, this connected mode, the connecting portion easy fracture damages bed surface easily.
The summary of the invention the purpose of this utility model provides the sick bed of firm, easy to use laborsaving, the non-damageable band hand crank of the bed surface lifting operating mechanism of a kind of overall structure.
The technical solution of the utility model is: it comprises back bed surface and the shank bed surface of dividing into lifting support; One end of the head of a bed is provided with the crank that the power transmission shaft that is connected with connecting rod below the bed surface is connected as a single entity, and is provided with the screw thread ratch corresponding with connecting rod, suit sheath on the screw thread ratch below the other end bed surface; Its main points are that the lifting support below said back bed surface and the shank bed surface is flexibly connected by hinge with sheath and connecting rod respectively; Said power transmission shaft is installed on the head of a bed by bearing block, and closely the power transmission shaft by the bearing block position is to be provided with automatic trip between two sections.
Said automatic trip comprises trocar sheath, and the trocar sheath inner end is provided with 60 ° of meshing gears of a pair of convex-concave, and the other end of concave gear is the cylinder bodily form, and its diameter and power transmission shaft are corresponding, and suit pushes away and connects spring on it; Push away the other end that connects spring and be provided with clamp sleeve, clamp sleeve is provided with dowel hole with the trocar sheath tube wall that pushes away the joint position that connects spring.
For the ease of fixing of alignment pin, the other end of said clamp sleeve is provided with hands and grips pipe.
This utility model is because the lifting support below back bed surface and the shank bed surface is flexibly connected by hinge with sheath and connecting rod respectively, and power transmission shaft is installed on the head of a bed by bearing block, makes the bed surface lifting flexible, laborsaving, and the support that bed surface is difficult for being ruptured stabs bad; Because power transmission shaft is divided between two sections and is provided with automatic trip, increased the bearing capacity of power transmission shaft again, overall structure is firm, has improved its service life.
