Abstract
The utility model provides a bed surface lifting support belonging to a device used in lifting a sickbed surface, wherein a handle is fixed on a transmission shaft; an eccentric wheel fixed on the transmission shaft is contacted with a push bolt arranged on a spring support; a rack arranged inside the spring support is meshed with the teeth arranged on the side face of a connecting rod head; one end of a connecting rod is fixed on the connecting rod head, while the other end is fixed with a gear support; the gear support has a gear arranged on an upper axis; one end of the rack is contacted with the push bolt; a spring is arranged between the other end of the rack and the spring support; a locating bolt which passes through a chute arranged on the rack is fixed on the spring support; the upper end of the support is arranged on the upper axis, while the lower end is arranged on a lower axis. The lifting support has a simple and reasonable structure and can conveniently adjust the bed surface angle of a sickbed, thereby ensuring that a patient can complete adjusting operation; moreover, because the lifting support occupies less lower space of a sickbed, a user can make full and reasonable use of the lower space of the sickbed.
Description
Technical field
This utility model provides a kind of device that is used for sick bed, especially a kind of device that is used for the patient couch top lifting.
Technical background
At present, the implementation of patient couch top lifting has hand-rail type mechanism and electrodynamic type mechanism.Hand-rail type mechanism can only lean on entourage or patient oneself operation of leaving the bed to realize, use inconvenience, and its lifting shaft is long, has almost taken whole sick bed lower space, therefore can not obtain the decline space of patient's lower limb, even the syllogic bed surface also is like this.Though electrodynamic type mechanism is easy to use, costs an arm and a leg, public ward is equipped with difficulty.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bed surface crane, to improve the convenience of patient couch top lifting.
This utility model is to realize like this, the bed surface crane, it has handle to be fixed on the power transmission shaft, the promotion bolt of installing on fixed eccentric and the spring support on the power transmission shaft contacts, tooth bar and the lateral tooth of connecting rod head installed in the spring support mesh together, connecting rod one end is fixed on the connecting rod head, the other end and gear stand are fixed together, the connecting rod outside has spring to be installed between connecting rod head and the spring support, there is gear to be installed on the axle on the gear stand, tooth bar one end contacts with the promotion bolt, between the other end and the spring support spring is arranged, the pilot pin that passes the skewed slot on the tooth bar is fixed on the spring support, and the upper end of support is installed on the axle, the lower end is installed on the lower shaft.
Adopt the bed surface crane of said structure, simple and reasonable for structure, can adjust the patient couch top angle easily, patient just can finish and adjust operation.It is little to take the sick bed lower space, and the sick bed lower space can obtain fully, reasonably use.This crane can also cooperate with five bending machine face framves of other design, makes patient obtain comfortable position.

The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, the bed surface crane of this utility model, it has handle 32 to be fixed on the power transmission shaft 33, the promotion bolt of installing on fixed eccentric 47 and the spring support 34 on the power transmission shaft 46 contacts, tooth bar 45 and the connecting rod head 40 lateral teeth installed in the spring support mesh together, connecting rod 31 1 ends are fixed on the connecting rod head, the other end and gear stand 42 are fixed together, the connecting rod outside has spring 41 to be installed between connecting rod head and the spring support, there is gear 37 to be installed on the axle 38 on the gear stand, tooth bar one end contacts with the promotion bolt, spring 43 is arranged between the other end and the spring support, the pilot pin 48 that passes the skewed slot 44 on the tooth bar is fixed on the spring support, and the upper end of support 35 is installed on the axle, the lower end is installed on the lower shaft 39.
As shown in Figure 4, when being installed to the crane of this utility model on the sick bed, the bed frame 52 of sick bed both sides is passed at the power transmission shaft two ends, and handle 32 is installed in a frame outside patient and stretches out one's hand the position that just can touch.Lower shaft 39 is installed on the bed frame of rear driveshaft.The tooth bar 51 of gear 37 below bed surface frame 50 meshes together.
When pulling handle 32, eccentric 47 rotates with power transmission shaft 33, and the part of protruding when eccentric rotates contacts with promoting bolt 46, overcomes the elastic force of spring 43, promotes tooth bar 45 and slides to the right.In the sliding process, because the skewed slot 44 on the tooth bar and the effect of pilot pin 48, tooth bar outwards moves along pilot pin, and the lateral tooth of tooth above it and union joint breaks away from, and connecting rod loses restriction.When support did not bear downward power (lifting as patient's body), under the elastic force effect of spring 41, in the connecting rod indentation spring support 34, rose in the upper end that drives support 35, the bed surface frame is lifted, and bed surface rises.If support 35 is applied a downward power (health being pressed down as patient), overcome the elastic force of spring 41, then the upper end of support 35 descends, and drives bed surface and descends.After bed surface rises or drops to correct position, oppositely pull handle, recess when eccentric rotates contacts with promotion bolt 46, tooth bar slides left under the effect of spring 43, and under the effect of pilot pin, move inward, tooth above it meshes together with the lateral tooth of union joint once more, realizes the restriction to connecting rod, the bed surface location.
A bearing 36 can be installed on gear stand, when installing this crane on one's sick bed, this bearing is installed in the lateral bearing runner 53 of bed surface frame, in the bed surface lifting process, bearing slides in bearing runner, to realize being connected between this crane and the bed surface, improve the reliability of moving between crane and the bed surface.
