As shown in fig. 4, two sets of linkage connecting rods 5 are respectively installed on two lateral sides of the first sub bed board 2 and the second sub bed board 3; the linkage connecting rod 5 is used for simultaneously driving the first auxiliary bed plate 2, the second auxiliary bed plate 3 and the supporting rod 4 to be folded or unfolded; the linkage lever comprises a V-shaped connecting rod, a sliding connecting rod 54 and a traction connecting rod 53; the V-shaped link includes a first link 51 and a second link 52 having one end rotatably connected to each other; the other end of the first connecting rod 51 is rotatably connected to the lateral side of the first sub bed board 2, and the other end of the second connecting rod 52 is rotatably connected to the lateral side of the second bed board; under the connection state of the V-shaped connecting rods, the first auxiliary bed board 2 and the second auxiliary bed board 3 can realize the state conversion process from mutual folding to mutual unfolding; one end of the sliding connecting rod 54 is rotatably connected to the supporting rod 4, the other end of the sliding connecting rod 54 is slidably connected in the sliding groove 31, and the sliding connecting rod 54 enables the supporting rod 4 to at least realize a state change process from the state of being perpendicular to the second auxiliary bed board 3 to the state of being parallel to the second auxiliary bed board 3; one end of the traction link 53 is rotatably connected to the connection point of the first link 51 and the second link 52 in the V-shaped link; the other end of the traction link 53 is rotatably connected to one end of the sliding link 54 connected to the chute 31; the rod pieces in the linkage connecting rod 5 rotate relatively along the connection points of each other in the vertical plane.

In the using process of a user, the folding principle of the auxiliary bed plate of the bed body is as follows:

when a user needs to unfold the auxiliary bed board, an operator grasps the outer side of the second auxiliary bed and pulls the second auxiliary bed board outwards, at the moment, the included angle between the first connecting rod 51 and the second connecting rod 52 in the V-shaped connecting rods is gradually enlarged, and meanwhile, the first auxiliary bed board 2 and the second auxiliary bed board 3 are unfolded. Meanwhile, the traction connecting rod 53 pulls the sliding connecting rod 54 at the other end along with the state change of the V-shaped connecting rod, so that the sliding connecting rod 54 moves to a position close to one end of the first sub bed board 2 along the sliding groove 31, and the supporting rod 4 is pulled to a state perpendicular to the board body of the second sub bed board 3 through the sliding connecting rod 54, so that the supporting rod 4 can well support the combination of the first sub bed board 2 and the second sub bed board 3.

Correspondingly, when the auxiliary bed board needs to be folded, only the second auxiliary bed board 3 needs to be grabbed and pushed inwards, so that the included angle between the first connecting rod 51 and the second connecting rod 52 in the V-shaped connecting rod is reduced, the first auxiliary bed board 2 and the second auxiliary bed board 3 are mutually attached to and accommodated on one side of the main bed board 1 and are perpendicular to the main bed board 1, and the first auxiliary bed board 2 and the second auxiliary bed board 3 at the moment are actually equivalent to the guardrail on the side surface of the main bed board 1. In the process of folding the first sub bed plate 2 and the second sub bed plate 3, the slide link 54 is slid to the other end of the slide groove 31 by the pulling force of the pull link 53, and the support rod 4 is changed to a state parallel to the plate surface of the second sub bed plate 3.

In this process, the function of the linkage link 5 is mainly two-fold: firstly, the linkage connecting rod 5 enables the motion states of the components to have linkage in the folding or unfolding process of the first auxiliary bed board 2, the second auxiliary bed board 3 and the supporting rod 4, so that the operation is convenient for a user, and the operation is convenient, fast and labor-saving; the first sub bed board 2, the second sub bed board 3 and the support rod 4 can be adjusted to corresponding positions at the same time by only slightly pulling or slightly pushing. Second, the stability of the first vice bed board 2 and the vice bed board 3 state of expansion of second has been guaranteed to linkage connecting rod 5, and when first vice bed board 2 and the vice bed board 3 of second expand, linkage connecting rod 5 not only plays the stable connection effect, can also play certain supporting role to prevent that first vice bed board 2 and the vice bed board 3 of second from warping because of the pressurized when using.

In the embodiment, the first auxiliary bed board 2 and the main bed board 1 are connected in a hinged manner, and the second auxiliary bed board 3 and the first auxiliary bed board 2 are also connected in a hinged manner; a hinge point between the main bed board 1 and the first auxiliary bed board 2 is positioned on one side of the main bed board 1 or the first auxiliary bed board 2 close to the front; the hinge point between the first auxiliary bed board 2 and the second auxiliary bed board 3 is positioned at one side of the back surface of the first auxiliary bed board 2 or the second auxiliary bed board 3.

Through this kind of articulated mode, can guarantee that first pair bed board 2 and the vice bed board 3 of second are pulled open the back, form a whole face that flushes between first pair bed board 2, the vice bed board 3 of second and the main bed board 1, avoid each board body height inconsistent and influence user's use and experience.

The thickness and the transverse width of the first auxiliary bed board 2 and the second auxiliary bed board 3 are the same; and when making first vice bed board 2 and the vice bed board 3 of second expand completely, the positive face of first vice bed board 2, the vice bed board 3 of second and main bed board 1 all flushes, and when first vice bed board 2 and the vice bed board 3 of second were folding, first vice bed board 2 and the vice bed board 3 of second laminate in main bed board 1 one side along vertical plane.

The length of the supporting rod 4 is equal to the vertical height between the back of the second auxiliary bed board 3 and the ground when the second auxiliary bed board 3 is stretched to be in a flat state.

The length of the support rod 4 is required to ensure that the support rod can form a stressed support just at the second auxiliary bed board 3 after the first auxiliary bed board 2 and the second auxiliary bed board 3 are unfolded; meanwhile, when the first auxiliary bed board 2 and the second auxiliary bed board 3 are folded, the supporting rod 4 cannot block the folding process. In practical application, a rod with adjustable length can be used instead of the support rod 4.

The rotatable connection modes of the rod bodies in the linkage connecting rod 5 and the rod bodies in the linkage lever and other structures all adopt pin shafts and revolute pairs as connecting pieces, and the extension direction of each pin shaft is along the longitudinal direction of the nursing bed.

The bottom of the support rod 4 is provided with a roller assembly 41, and the roller assembly 41 comprises a braking device. The roller assemblies 41 at the bottom of the support rod 4 can facilitate the movement of the bed body.

Example 2

This example differs from example 1 in that: in this embodiment, as shown in fig. 5, the two ends of the sliding slot 31 in the second sub bed board 3 are further provided with positioning slots 311, and the extending direction of the positioning slots 311 is perpendicular to the extending direction of the sliding slot 31; the widths of the positioning slot 311 and the sliding slot 31 are both matched with the diameter of a pin shaft clamped in the positioning slot 311 or the sliding slot 31, a pin cap is arranged at the part of the pin shaft positioned in the positioning slot 311 or the sliding slot 31, and the diameter of the pin cap is larger than the width of the positioning slot 311 or the sliding slot 31.

The two ends of the sliding chute 31 are the positions of the movable end of the sliding connecting rod 54 when the auxiliary bed board is in the fully unfolded and fully folded states. Therefore, after the positioning grooves 311 are formed at the two ends of the sliding groove 31, the sliding connecting rod 54 can just slide into the positioning grooves 311 when moving to the end of the sliding groove 31, and the unfolded or folded bed plate has a certain locking characteristic, so that the first sub bed plate 2 or the second sub bed plate 3 can be prevented from rotating to cause dangerous accidents in the using process of a user. Usually, only when the user pulls or pushes or pulls with force, the pin shaft slides into the sliding groove 31 again, so as to realize the state conversion of the auxiliary bed board.

Example 3

This example differs from example 2 in that: in this embodiment, as shown in fig. 6, the back surfaces of the first sub bed board 2 and the second sub bed board 3 are both provided with grooves 30 which are arranged in the transverse direction and extend to the front surface of the first sub bed board 2 or the second sub bed board 3; the number of the grooves 30 is the same as that of the linkage connecting rods 5, and the linkage connecting rods 5 are arranged on the side walls of the first auxiliary bed plate 2 or the second auxiliary bed plate 3 in the grooves 30; the width, length and depth of the groove 30 are such that the groove 30 allows the link 5 or the support bar 4 to freely rotate within limits.

In the present embodiment, the link rod 5 is not directly mounted on both ends of the first sub bed plate 2 and the second sub bed plate 3, but is mounted in the groove 30 formed in the first sub bed plate 2 and the second sub bed plate 3, and the link rod 5 is received in this manner. The arrangement of the groove 30 not only makes the whole nursing bed more concise and beautiful, but also can protect the user from being clamped to certain parts of the body by the rod piece in the motion state in the linkage connecting rod 5 when in use. Meanwhile, the groove 30 can also protect the linkage connecting rod 5, and the damage to the performance or the service life of the component caused by the foreign matter clamped in the linkage connecting rod 5 is avoided.

Example 4

This example differs from example 3 in that: as shown in fig. 7, in this embodiment, cover plates 32 are further disposed on two sides of the first sub bed board 2 and the second sub bed board 3, and the cover plates 32 are detachably connected to the first sub bed board 2 or the second sub bed board 3; a gap for the linkage connecting rod 5 or the supporting rod 4 to move freely within the limit is arranged between the cover plate 32 and the first auxiliary bed plate 2 or between the cover plate 32 and the second auxiliary bed plate 3.

In embodiment 3, the linkage connecting rod 5 is installed in the groove 30 formed in the first sub bed board 2 and the second sub bed board 3, and this kind of groove 30 may cause certain influence to the structural strength of the first sub bed board 2 and the second sub bed board 3, therefore in this embodiment, the linkage connecting rod 5 is still installed at the first sub bed board 2 and the second sub bed board 3 side, but the position of installing the linkage connecting rod 5 in the first sub bed board 2 and the second sub bed board 3 sets up the cover plate 32, the cover plate 32 can cover the linkage connecting rod 5, play the same pleasing to the eye and the guard effect with embodiment 3, and there is no influence to the structural strength of the first sub bed board 2 and the second sub bed board 3 simultaneously.

Example 5

This example differs from example 1 in that: in this embodiment, as shown in fig. 8, the traction link 53 of the linkage link 5 is an elastic rod, one end of which is rotatably connected to the second link 52 and the other end of which is rotatably connected to the slide link 54.

The traction link 53 in the linkage link 5 in embodiment 1 is a rigid rod, which has the advantages of high structural strength and supporting function, but the linkage link 5 has a certain jerking feeling in the deformation process of the sub-bed plate structure, and can cause abrasion to the chute 31 after long-term use.

In this embodiment, the traction link 53 is replaced with an elastic member, so that the above-mentioned problems can be effectively solved. For example, the elastic rod may be a spring or other rod that can achieve similar effects in practical applications; when the traction link 53 is a spring, it can be found that, besides the traction function, the spring is compressed or stretched in the process of folding or unfolding the auxiliary bed board, so that the spring can actually realize the effect of automatic reset through the elasticity of the spring, and the user can save more labor when unfolding or folding the auxiliary bed board.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
