As shown in fig. 1, the nursing bed provided in the embodiment of the present invention is used for nursing and rehabilitation treatment of special people such as the elderly and diseases, and is generally used in places such as hospitals, nursing homes, and rehabilitation medical centers.

The nursing bed can be an electric nursing bed or a manual nursing bed according to the classification of the types. Taking an electric nursing bed as an example, the electric nursing bed generally comprises a bed body 90, a bracket, rollers and other components, has various auxiliary treatment functions, and mainly comprises back lifting, leg bending, lifting, front and back tilting, left and right turning, defecation and the like. The nursing bed generally realizes special body positions through a multi-link mechanism, so that a user can have a rest more comfortably, and the sleeping quality is greatly improved. Some special positions have special effects on patient care, for example, the trendelenberg position can effectively improve the respiratory quality of a human body during sleeping.

The lifting function of the nursing bed can realize that the position of the bed body 90 (the bed body 90 is a main structural member of the nursing bed) is greatly reduced, and effectively avoids the damage of the old and the patients caused by falling from the bed at night. In addition, the nursing bed also comprises a guardrail device and a plurality of accessories. In particular, the barrier device comprises a lifting barrier 10. The guardrail device in this embodiment preferably includes at least two lifting guardrails 10 (it can be understood that the two lifting guardrails 10 have the same or most of the same structure), which are arranged side by side, and the two lifting guardrails 10 can be installed on the same side of the bed 90 or on the left and right sides of the bed 90 respectively. When a patient lies in bed normally, the lifting guardrails 10 on the two sides keep the stretching posture (refer to fig. 2), so that the patient can be laterally protected; when the patient needs to get on or off the bed, the barrier device can be retracted to release the enclosure (see fig. 3) so that the patient can get on or off the bed. Preferably, because the bed 90 has a large length, two lifting guardrails 10 can be installed on one side of the bed 90 at the same time as shown in fig. 1.

It will be appreciated that extension or retraction of the barrier device may be accomplished automatically by mechanical means, or manually by manual means; when the guardrail devices on the two sides work, one guardrail device can be selected or can synchronously ascend or descend; the concrete can be selected according to actual needs.

Continuing to refer to fig. 2 and 3, a lifting fence 10 of one embodiment of the present application is shown, comprising: fixed stand 11, plaque 12, lift stand 13 and baffle 14. In this embodiment, the fixed column 11 and the lifting column 13 are both hollow pipes with two ends penetrating through, and may be, for example, square pipes, circular pipes, or special pipes. The shape of the lifting upright column 13 is matched with the shape of the inner cavity of the fixed upright column 11, but the maximum shape size is smaller than the size of the inner cavity of the fixed upright column 11, so that the lifting upright column 13 can be nested in the fixed upright column 11 and can move smoothly in a lifting mode.

In order to ensure the beautiful appearance of the product, the top end of the lifting upright post 13 is provided with an upper end cover. And a protective cover made of soft materials such as rubber is sleeved outside the upper end cover for protecting the safety of the patient.

The bottom end of the fixed upright post 11 is provided with a lower end cover to ensure stable standing and prevent external impurities, pests and the like from invading into the lifting guardrail 10 to damage the inside.

The plaque 12 is arranged on the fixed upright post 11, and the top surface of the plaque 12 is not higher than the bed surface of the bed body 90; the lifting upright column 13 is arranged on the fixed upright column 11 in a lifting and sliding manner; the baffle 14 is arranged on the lifting upright post 13, and when the lifting upright post 13 slides and descends along the fixed upright post 11, the baffle 14 can synchronously descend along with the lifting upright post 13 and is hidden inside the plaque 12.

It can be understood that, when the fixed column 11 and the lifting column 13 are both one, the same end of the trim 12 and the baffle 14 is correspondingly mounted on the outer walls of the lifting column 13 and the fixed column 11, respectively, that is, the trim 12 and the baffle 14 adopt a cantilever type mounting structure. Simple structure, novel and beautiful appearance. And it will be appreciated that the tile 12 serves a decorative aesthetic function.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the guardrail device of the scheme is applied to equipment in a nursing bed, and particularly, two lifting guardrails 10 are respectively arranged on the left side and the right side of a bed body 90 so as to play a role in lateral shielding and protecting a patient lying in bed and ensure the safety of the patient lying in bed. Specifically, the main body of the lifting guardrail 10 is composed of a fixed upright 11 and a lifting upright 13, wherein the lifting upright 13 can ascend or descend and slide relative to the fixed upright 11. In the initial state, the lifting upright post 13 extends out relative to the fixed upright post 11, and the baffle plate 14 is positioned at the blocking and protecting working position, so that good lateral blocking and anti-falling effects can be achieved for the bedridden patient. When a patient needs to get on or off the bed, the lifting upright post 13 can be pressed, the lifting upright post 13 can slide and descend, the baffle plate 14 can synchronously descend along with the lifting upright post, and when the lifting upright post 13 descends to the lowest position, the baffle plate 14 can be completely hidden inside the decorative plate 12 which is arranged on the fixed upright post 11 in advance, namely when the nursing bed is observed from the outside, only the decorative plate 12 can be seen, but the baffle plate 14 cannot be seen. Therefore, the baffle plate 14 with the function of enclosure is not exposed in the visual field of the patient, and unfriendly psychological suggestion is not generated to the patient, thus being beneficial to the physical and psychological health recovery of the patient; and because the top surface of the plaque 12 is designed to be not higher than the bed surface of the bed body 90, when the baffle 14 is completely hidden inside the plaque 12, the baffle 14 does not exceed the bed surface of the bed body 90, namely, the height of the baffle 14 after descending does not hinder the operation of getting on or off the bed of a patient, the use experience of the nursing bed can be improved, and potential safety hazards are eliminated.

With reference to fig. 2 to 5, in addition to the above, in some embodiments, the guardrail apparatus further includes a cross bar body 20 and a connecting rod 30 disposed at an end of the cross bar body 20, the cross bar body 20 is assembled and fixed with the lifting upright 13 through the connecting rod 30, and the baffle 14 is disposed at a bottom of the cross bar body 20. Specifically, the lifting upright 13 is provided with a jack facing the side of the cross rod body 20, one end of the connecting rod 30 is fixedly arranged inside the cross rod body 20, and the other end of the connecting rod is inserted and fixed in the jack, so that the cross rod body 20 and the lifting upright 13 are assembled and fixed, and the baffle 14 can be integrally connected with the lifting upright 13 by being connected with the cross rod body 20, thereby realizing the integral synchronous ascending or descending of the three. The baffle 14 is arranged on the cross bar body 20, and the side surface of the baffle 14 is in clearance fit with the fixed upright post 11, so that the baffle 14 is prevented from interfering with the fixed upright post 11 when the lifting upright post 13 descends.

With continued reference to fig. 5, in some embodiments, the barrier device further includes a switch mechanism 40 and a locking mechanism 50, the switch mechanism 40 is disposed in the rail body 20, the locking mechanism 50 is disposed in the lifting column 13, the switch mechanism 40 is configured to control the locking mechanism 50 to switch between a locking state and an unlocking state, and the locking mechanism 50 is configured to lock the lifting column 13 and the fixed column 11 or unlock the lifting column 13 and the fixed column 11. That is, by locking and fixing the lifting column 13 and the fixed column 11 by the locking mechanism 50, it can be ensured that the lifting column 13 maintains the extending posture, and the guardrail apparatus is in a reliable enclosure state. When the switch mechanism 40 is operated, the locking mechanism 50 can release the locking relationship between the lifting column 13 and the fixed column 11, i.e. the lifting column 13 can descend and contract relative to the fixed column 11, so that the lifting guardrail 10 can be quickly and conveniently switched to the structural form, and a patient can get on or off the bed conveniently.

Specifically, in some embodiments, the switch mechanism 40 includes a switch body 41 and a pull assembly connected to the switch body 41. The cross bar body 20 is a square cylinder body and can be made of stainless steel, aluminum alloy and other materials. The front side surface and the rear side surface of the cross bar body 20 (i.e. the two side surfaces along the width direction of the bed body 90) are provided with through holes, the switch body 41 comprises a first switch shell and a second switch shell, and the first switch shell and the second switch shell are respectively inserted into two hole ends of the through holes. In addition, the first switch case and the second switch case are each provided with a vertically slidable clip plate for outputting a driving force for locking or unlocking the lock mechanism 50.

Referring to fig. 7, the locking mechanism 50 includes a lock base 51, a first lock body 52 disposed on the lock base 51, a second lock body 53 disposed on the first lock body 52, and a third lock body 54 connected to the lifting assembly, the third lock body 54 has a wedge surface 541, the wedge surface 541 abuts against the second lock body 53, the inner wall of the fixed upright post 11 has a lock hole 111, and the first lock body 52 can be inserted into the lock hole 111 or removed from the lock hole 111. With continued reference to fig. 5 and 6, the pulling assembly is connected between the switch body 41 and the locking mechanism 50 for transmitting a driving force applied to the switch body 41 for unlocking or locking. In some embodiments, the lifting assembly includes a mounting plate 42 disposed inside the crossbar body 20, a guiding post 43 disposed on the mounting plate 42, a driving rod 44 slidably disposed on the guiding post 43, and a lifting rod 45 connected to the driving rod 44, wherein the lifting rod 45 is connected to the third latch 54, and the driving rod 44 is further connected to the switch body 41. The mounting plate 42 is used for mounting and fixing the guide posts 43 on the inner wall of the cross bar body 20, and the guide posts 43 are vertically arranged. The driving rod 44 is connected with the buckle plate of the switch body 41, when the switch body 41 is pressed downwards, the driving rod 44 slides downwards along the guide post 43, and the driving rod 44 further can drive the lifting rod 45 to move so as to draw the third lock body 54 to move upwards, so that the first lock body 52 can be separated from the lock hole 111, and the unlocking of the lifting upright post 13 and the fixed upright post 11 is realized. It can be understood that the guide column 43 plays a role in guiding and limiting the lifting movement of the switch body 41.

Specifically, when the buckle plate is pressed downwards, the buckle plate can drive the lifting rod 45 to move transversely, the lifting rod 45 further pulls the third lock body 54 to move vertically upwards, because the wedge surface 541 on the third lock body 54 is abutted against the second lock body 53, in the process of moving upwards along with the third lock body 54, the second lock body 53 can be pushed by the wedge surface 541 to move backwards (i.e. move leftwards in fig. 7), the second lock body 53 synchronously drives the first lock body 52 to move backwards, the first lock body 52 is disengaged from the lock hole 111, and the lifting upright post 13 and the fixed upright post 11 are unlocked, so that the cross rod body 20, the baffle plate 14, the lifting upright post 13 and other components can descend under the self weight, and the purpose of retracting the lifting guardrail 10 is achieved.

In particular, in order to reduce the contact friction resistance between the second lock body 53 and the third lock body 54, when the third lock body 54 is driven to move upwards, the wedge surface 541 can more easily drive the second lock body 53 and the first lock body 52 to move for unlocking. In some embodiments, the second lock body 53 is provided with an arc surface portion, and the arc surface portion abuts against the wedge surface 541. At this time, the arc surface portion is in line contact with the wedge surface 541, the contact area is small, and further, under the frictional resistance during the relative movement, the driving response speed of the third lock body 54 to the first lock body 52 can be ensured to be high, and the third lock body is smoother.

The wedge surface 541 is inclined in a direction from the third lock body 54 to the lock holder 51, and is inclined downward from the upper right to the lower left.

Of course, it should be noted that, in other embodiments, other unlocking mechanisms in the prior art may also be used, as long as the first lock body 52 can be driven to be disengaged from the lock hole 111.

It should be noted that the second lock 53 may have any structural shape, and the arc surface portion is an outer convex arc surface structure formed by the contact portion of the second lock 53 and the third lock 54. Alternatively, the second lock body 53 may be directly configured as a cylinder, and the arc surface refers to an outer cylindrical surface of the cylinder.

In addition, it should be further noted that, on the basis of any of the above embodiments, preferably, two sets of the fixed columns 11, the lifting columns 13, the connecting rods 30, the locking mechanisms 50 and the pulling assemblies are respectively assembled and connected in a one-to-one correspondence manner, and two sets of the fixed columns 11, the lifting columns 13, the connecting rods 30, the locking mechanisms 50 and the pulling assemblies are respectively arranged at two opposite ends of the cross bar body 20. So not only can guarantee to support fixedly more firm to horizontal pole body 20 and baffle 14, can avoid simultaneously that lifting column 13 leads to the fact the card to die toward one side skew because of the focus skew when moving, influences lifting guardrail 10 normal use and experiences.

Referring to fig. 5 and 7, as mentioned above, the purpose of lowering the lifting columns 13 is to lower the height of the lifting fence 10 to facilitate the patient to get on or off the bed, and the baffle 14 is hidden inside the decorative plate 12 to avoid the patient from making an uncomfortable psychological hint to the patient and affecting the physical and mental health recovery. When the patient lies on the bed, the lifting upright post 13 needs to be lifted again, so that the baffle plate 14 and the cross bar body 20 can laterally shield the patient to prevent the falling accident. In order to enable the first lock body 52 to be quickly and reliably inserted into the lock hole 111 again during the lifting process of the lifting column 13, in some embodiments, the locking mechanism 50 further includes a first elastic resetting member 55, the first elastic resetting member 55 is connected between the lock seat 51 and the first lock body 52, and the direction of the telescopic deformation of the first elastic resetting member 55 is parallel to the moving direction of the first lock body 52. It will be appreciated that when the third latch body 54 drives the first latch body 52 back, the first resilient return member is compressed and continues to remain compressed by the abutment of the wedge surface 541 with the second latch body 53. When the lifting upright post 13 needs to be lifted, the switch body 41 is firstly lifted, at this time, the lifting rod 45 pushes and presses the third lock body 54 downwards, the third lock body 54 gradually falls downwards, the wedge surface 541 gradually loses the abutting constraint on the second lock body 53, so the first elastic resetting piece 55 extends and resets under the action of the self elastic force to push the first lock body 52 to move forwards until being inserted into the lock hole 111, the lifting upright post 13 and the fixed upright post 11 are locked again, and the lifting upright post 13 can carry the cross bar body 20 and the baffle 14 to be reliably stopped at the preset height position together, thereby exerting the lateral blocking and protecting effect.

Alternatively, the first elastic restoring member 55 may be, but is not limited to, a spring, an elastic column, an elastic sheet, etc.

Further, in order to reduce the force applied by the patient to operate the switch body 41, the operation experience is improved, and the third lock body 54 is more easily lowered and reset. In some embodiments, the locking mechanism 50 further includes a second elastic restoring member 56 and a mounting member 57, one end of the second elastic restoring member 56 is connected to the third lock body 54, the other end of the second elastic restoring member 56 is connected to the mounting member 57, the mounting member 57 is further connected to the lock base 51, and the direction of the expansion and contraction deformation of the second elastic restoring member 56 is parallel to the moving direction of the third lock body 54. Alternatively, the second elastic return element 56 is a tension spring and the corresponding mounting element 57 is a tension spring mounting. When the switch body 41 is pressed to move the third lock body 54 upwards, the tension spring is stretched to be lengthened; when the switch body 41 is pulled, the third lock 54 tends to fall down, so that the third lock can fall down more quickly under the action of the rebounding pulling force of the second elastic reset piece 56, thereby saving the force of the patient for pulling the switch body 41.
