Description
Technical field
The utility model relates to a kind of parts of beddo, is specifically related to a kind of automatic backward shift device of beddo.
Background technology
Beddo is medical treatment, recuperates or other nursing units and the frequent equipment that uses of individual.Its structure is: beddo is provided with a fixing rectangle steel bedstead, and there are two rotating shafts at the middle part, and two side levers that are used to support the bed board subregion are fixed in this movable stand rotating shaft; Moving up and down frame is connected with flexible motor by connecting rod.Move up and down the lifting (rotating by a small margin) of frame around the movable stand rotating shaft by the action push-and-pull of flexible motor; Each supporting arrangement at flexible motor and subregion position is fixed on the rectangular frame side of beddo upper frame of beddo.In the use of beddo, comfortable for lying position, often needs are adjusted the position of each subregion of beddo.Beddo is after mixing up the position, and the main position of human body especially head can make beddo directly carry human body and leave the bed screen because the height of beddo district location changes a certain amount of displacement that produces with respect to the bed screen, exposes the space.This brings certain influence can for the end user in real life.For example, the change of seeing berth in the TV process makes the change of people and television set distance, brings visual discomfort to the people.The space that object falls between beddo and the bed screen also can bring inconvenience.But the beddo of prior art can't be tackled this situation, can bring to a certain extent inconvenience to the user like this.
Summary of the invention
At the above-mentioned deficiency of prior art, the purpose of this utility model provides a kind of automatic backward shift dress of beddo, and this device uses in back or the use at beddo, and especially the horizontal level of head is constant with respect to the bed screen can to guarantee human body.To realize the environment for use of human comfort nature.
The technical scheme of finishing the foregoing invention task is: a kind of automatic backward shift device of beddo, and beddo is provided with the rectangle bedstead, and the middle part of this rectangle bedstead is provided with the movable stand rotating shaft, and the side lever that is used to support the bed board active partition is fixed in this movable stand rotating shaft; Moving up and down frame is connected with flexible motor by connecting rod, each supporting arrangement at flexible motor and subregion position is fixed on the described rectangle bedstead side lever, it is characterized in that described rectangle bedstead is made as upper frame, four rollers are equipped with in the bottom of this upper frame; Be provided with the underframe that shields fixed connection with bed below this upper frame, this underframe is provided with guide rail; Described four rollers are installed on this guide rail; Simultaneously, the side lever of described bed screen both sides, bottom and the upper frame first subregion supporting part both sides respectively is provided with a traction link and connects; Its bind mode is, these traction link two ends are equipped with axle sleeve, and the traction link two ends are linked on the side lever of beddo bed screen both sides, bottom and the beddo upper frame first subregion supporting part by axle sleeve and rotating shaft respectively.
The general beddo of prior art is to be provided with two movable stand rotating shafts and two connecting rods that are connected with flexible motor.But the utility model goes for the beddo of two movable stand rotating shafts and two connecting rods that are connected with flexible motor, is applicable to that also one or more movable stand rotating shafts are connected the beddo of connecting rod with one or more and flexible motor.
Operation principle of the present utility model is to change the rectangle bedstead into revocable bedstead (upper frame).When stretching machine operation, can draw the rotation that certain angle is made in the upper frame rotating shaft, when push-and-pull moves up and down the frame lifting, can pulling be linked in the traction link that bed shields, thereby the traction upper frame is done the relative motion of front and back position, and at this moment first subregion (subregion at human body head place) can keep constant substantially with respect to the horizontal range of bed screen.Just, when flexible motor extended, partition sections can flatten, and a traction link that at this moment is linked in bed screen end can promote upper frame, guaranteed in the first subregion dropping process constant with bed screen relative position; Otherwise when flexible motor shortened, the subregion position can be gone up to lifting, and the traction link that then is linked in bed screen end can spur upper frame, and is constant with bed screen relative position in uphill process to guarantee first subregion.
Prioritization scheme of the present utility model has:
1, two traction link of described beddo backward shift device are provided with one section arcs of recesses changeover portion, and this arcs of recesses changeover portion is positioned at an end of the nearly bed screen of traction link.This arcs of recesses changeover portion is in order to utilizing the useful space of beddo, and can eliminate and move up and down the dead position that produces when frame is in level.This connecting rod arcs of recesses transition can be because of flexible motor movement, and does the flexible motion up and down in the certain limit.
2, two of described underframe are equipped with the decoration guardrail.
Beddo backward shift device of the present utility model has overcome the deficiencies in the prior art, can eliminate the space that beddo produces between the bed screen in lifting process automatically, makes beddo guarantee that in use the human body head front and back position is constant relatively; Realized improving under the normal condition the conventional environment for use of human body, be unlikely producing certain visual bad reaction.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1, the automatic backward shift device of a kind of beddo, with reference to Fig. 1: each supporting arrangement at flexible motor 7 and subregion position is fixed on the side of described rectangular frame (upper frame) 1, automatic backward shift of the present utility model position device is installed on beddo upper frame 1 and the underframe 2, its structure is: the two ends of two spill connecting rods 3 of beddo be connected in respectively with the both sides of the bed screen 8 of underframe 2 fixed connections and upper frame 1 on the side lever 4 of the first subregion supporting part, upper frame 1 dual-side is equipped with four rollers 5, roller can allow upper frame 1 move forward and backward on the guide rail 6 that underframe forms.When flexible motor 7 is worked, the rotation of certain angle is done in the rotating shaft 9 that can draw upper frame 1, when push-and-pull moves up and down the lifting of frame, can make the side lever of the supporting part of both sides draw the relative motion that upper frame 1 is made front and back position, at this moment first subregion (subregion at human body head place) can keep constant substantially with respect to the horizontal range of bed screen 8.
