DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] See also Figure 1-5The present invention provides a technical solution: a variable width hospital bed, comprising support legs 1, a first bed body 2 is fixedly connected to the front of the two groups of support legs 1 at the rear side, and a second bed body 3 is fixedly connected to the back of the two groups of support legs 1 at the front side. The first bed body 2 is movably embedded in the interior of the second bed body 3. The outer diameter of the first bed body 2 is smaller than the inner diameter of the second bed body 3. Therefore, the first bed body 2 is movably inserted into the interior of the second bed body 3, so that the outer side surface of the first bed body 2 is movably in contact with the inner wall of the second bed body 3. Therefore, the second bed body 3 is slidably sleeved on the first bed body 2. The outer side of the first bed body 2 and the second bed body 3 can be produced in accordance with the actual situation in actual production, as long as the second bed body 3 can be sleeved on the outer side of the first bed body 2. The bottom of the front side of the rear support leg 1 is fixedly connected to the limiting frame 4, and the inner part of the limiting frame 4 is slidably connected to the limiting plate 5. The front side of the limiting plate 5 is fixedly connected to the back side of the front support leg 1. A bidirectional screw 6 is provided through the middle of the outer side of the limiting frame 4 and the limiting plate 5. The bidirectional screw 6 is made on a screw with two sections of threads with different rotation directions, that is, one section of right-handed. Thread, a section of left-hand thread, because the two sets of hinges 9 are respectively threadedly sleeved on the left and right sides of the bidirectional screw rod 6, therefore, when the bidirectional screw rod 6 rotates, the two sets of hinges 9 will approach or separate, thereby producing the required mechanical function, the outer surfaces of both ends of the bidirectional screw rod 6 are fixedly sleeved with limit rings 7, the inner side of the limit ring 7 is in active contact with the outer side of the limit plate 5, the left end of the bidirectional screw rod 6 is fixedly connected with a hand-cranked wheel 8, the left and right sides of the outer surface of the bidirectional screw rod 6 are sleeved with hinges 9, the two sets of hinges 9 are threadedly connected to the bidirectional screw rod 6, and the internal hinges of the hinges 9 A transmission rod 10 is connected, and a fixing bolt 11 is movably inserted at the outer end of the transmission rod 10. The top ends of the two groups of fixing bolts 11 on the front side are fixedly connected to the front side of the lower surface of the first bed body 2, and the top ends of the two groups of fixing bolts 11 on the rear side are fixedly connected to the rear side of the lower surface of the second bed body 3. A universal wheel 13 is fixedly connected to the bottom end of the supporting leg 1. The universal wheel 13 is an existing product, so it is not introduced in detail here. At the same time, when the device is produced, the universal wheel 13 can also be replaced with a brake-type universal wheel. The brake-type universal wheel has the function of braking in situ, which can improve the stability of the bed.
[0026] When the hand-cranked wheel 8 is controlled to drive the bidirectional screw rod 6 to rotate in a specified direction, due to the rotatability of the universal wheel 13, the first bed body 2 and the second bed body 3 will move outward, so that the first bed body 2 and the second bed body 3 are unfolded, thereby increasing the overall width of the first bed body 2 and the second bed body 3 combined, so that the bed can achieve the function of rapid widening, which is convenient for providing a suitable resting position for patients with larger bodies or family members and spouses of patients with specific emotional and psychological care needs, greatly improving the practicality of the device. At the same time, the device uses a relatively small and simple structure to achieve the function of variable width, has a low manufacturing difficulty, is simple to operate, and is suitable for promotion.
[0027] By setting the foldable guardrail 14, the patient can be blocked and prevented from falling when resting or turning over, thereby ensuring the patient's personal safety. At the same time, due to the setting of the compression strip 18, one side of the mattress and the bed sheet can be compressed, so that the bed sheet and the mattress can move with the second bed body 3. At the same time, the patient can also lie on the second bed body 3 without moving, so that the device can be widened, saving time and effort.
[0028] In the present invention, in order to ensure the stability of the transmission rod 10 during operation, a reinforcement ring 12 is fixedly sleeved on the top of the outer surface of the four groups of fixing bolts 11, and the lower surface of the reinforcement ring 12 is in active contact with the upper surface of the outer end of the transmission rod 10. The upper surfaces of the two groups of reinforcement rings 12 on the front side are fixedly connected to the front side of the lower surface of the first bed body 2, and the upper surfaces of the two groups of reinforcement rings 12 on the right side are fixedly connected to the rear side of the lower surface of the second bed body 3. Because of the provision of the reinforcement ring 12, the connection area between the fixing bolts 11 on the front and rear sides and the first bed body 2 and the second bed body 3 is increased, respectively, to prevent the connection position from being easily broken. At the same time, because the lower surface of the reinforcement ring 12 is in active contact with the outer end of the transmission rod 10, the outer end of the transmission rod 10 can be limited so that the outer end of the transmission rod 10 can only rotate at the bottom of the outer surface of the fixing bolt 11 to prevent shaking. In two ways, the stability of the transmission rod 10 during operation is effectively guaranteed.
[0029] In the present invention, in order to protect the safety of the patient and prevent the patient from falling off the bed, a folding guardrail 14 is provided on the back of the first bed body 2 and the front of the second bed body 3. The folding guardrail 14 is a product structure commonly used in existing hospital beds. The folding guardrail 14 is usually composed of an upper cross bar, a lower cross bar and a column. Because it is an existing known structure, it is not described in detail here. The folding guardrail 14 is unfolded upward so that it can effectively block the patient and prevent the patient from falling off when sleeping or turning over. Therefore, the safety of the patient is protected and the patient is prevented from falling off the bed.
[0030] In the present invention, in order to prevent the mattress and bed sheets that exceed the width of the bed from being placed on the folding guardrail 14, causing the folding guardrail 14 to be inconvenient to unfold and fold, a long through groove 15 that runs through from top to bottom is opened on the rear side of the outer side surface of the first bed body 2 and the front side of the outer side surface of the second bed body 3. Due to the setting of the long through groove 15, the user can extend the mattress and bed sheets that exceed the width of the bed into the interior of the long through groove 15, thereby preventing the mattress and bed sheets that exceed the width of the bed from being placed on the folding guardrail 14, causing the folding guardrail 14 to be inconvenient to unfold and fold. At the same time, the aesthetics of the device when being used is also improved.
[0031] In the present invention, in order to facilitate the first bed body 2 and the second bed body 3 to unfold and widen, a fixing block 16 is fixedly connected to the frontmost side of the lower surface of the second bed body 3, and a fixing shaft 17 is inserted through the outer side surface of the fixing block 16. A clamping strip 18 is movably sleeved on the left side of the outer surface of the fixing shaft 17. The middle part of the outer surface of the clamping strip 18 is convex downward, so that a gap is left between the convex position and the second bed body 3, so that the staff can easily put their palms into this space, and then directly hold the clamping strip 18, and then pull the clamping strip 18, which is convenient for the staff to tighten and loosen the bed belt and the mattress, saving time and effort, and facilitating the operation of the staff. The top of the outer surface of the clamping strip 18 is against the front side of the lower surface of the second bed body 3, and the outer surface of the fixing shaft 17 is sleeved with a torsion spring 19, and one end of the torsion spring 19 is against the first The lower surface of the second bed body 3 has its other end placed on the outer surface of the pressing strip 18. Due to the setting of the torsion spring 19, the pressing strip 18 can be tightly pressed against the lower surface of the second bed body 3. At the same time, when the first bed body 2 and the second bed body 3 are widened and unfolded, the user can pull the pressing strip 18 open, and then fold the part of the mattress and bed sheet that exceeds the width of the bed body and extends into the long through groove 15 on the front side to the rear side, and then release the control of the pressing strip 18, so that the pressing strip 18 can firmly press a part of the mattress and bed sheet, and at the same time pull out the mattress and bed sheet that extend into the long through groove 15 on the rear side. Then, when the first bed body 2 and the second bed body 3 are widened and unfolded, the mattress and bed sheet will move with the second bed body 3, and the patient on the mattress and bed sheet does not need to move, which saves time and effort and facilitates the first bed body 2 and the second bed body 3 to unfold and widen.
[0032] In the present invention, in order to improve the stability of the limit frame 4 and the limit plate 5 when they are in use, a triangular plate is fixed to the outermost side of the lower surface of the limit frame 4 and the limit plate 5, and the outer side surface of the triangular plate is fixed to the inner side surface of the support leg 1. The triangular plate increases the connection area between the limit frame 4 and the limit plate 5 and the support leg 1 located at the rear side and the support leg 1 located at the front side, respectively, thereby improving the fixing effect and improving the stability of the limit frame 4 and the limit plate 5 when they are in use.
[0033] In the present invention, in order to facilitate the sliding of the limit frame 4 and the limit plate 5 along the outer surface of the bidirectional screw rod 6, left and right through grooves are opened on the outer side surfaces of the limit frame 4 and the limit plate 5, and the inner diameter of the through groove is matched with the outer diameter of the outer end of the bidirectional screw rod 6. Therefore, due to the matching of the sizes, it is convenient for the limit frame 4 and the limit plate 5 to slide along the outer surface of the bidirectional screw rod 6.
[0034] In the present invention, in order to extend the service life of the torsion spring 19, the number of torsion springs 19 is set to several groups, and the manufacturing material of the several groups of torsion springs 19 is set to silicon manganese spring steel. The silicon manganese spring steel material has good fatigue resistance, high strength, and good rebound effect. Therefore, the service life of the torsion spring 19 can be extended.
[0035] When in use, the staff can move the device to a designated position because of the setting of the universal wheel 13. When the patient uses it, because the first bed body 2 is stored inside the second bed body 3 before it is widened, the mattress and bed sheet are first laid on the second bed body 3 in this way, and then the longer edges of the extra mattress and bed sheet are respectively stuffed into the inside of the long through grooves 15 on both sides to ensure its aesthetics and neatness, and at the same time it will not hinder the unfolding of the folding guardrail 14. When the patient needs to rest, the folding guardrail 14 is unfolded to prevent the patient from falling down when turning over. When night comes and the patient's family members have no place to rest, the accompanying family members first stuff the folding guardrail 14 into the inside of the long through groove 15 on the rear side. The longer part of the edge of the mattress and the sheet is pulled out, and then the pressing strip 18 is pulled open, and then one side of the mattress and the sheet that are inserted into the front unobstructed operation is folded to the inner side of the pressing strip 18 and the second bed body 3, and then the pressing strip 18 is restored to its original position. At the same time, due to the setting of the torsion spring 19, the pressing strip 18 can be firmly pressed on the mattress and the sheet. Then, the accompanying family member controls the hand-cranked wheel 8 to drive the two-way screw rod 6 to rotate in the specified direction along the inside of the through groove, and at the same time drives the limiting ring 7 to rotate. Because of the setting of the two sets of limiting rings 7, the rotating two-way screw rod 6 can be effectively limited to ensure the stability of the two-way screw rod 6. At the same time, due to the characteristics of the two-way screw rod 6, the two-way screw rod 6 can be divided into two groups. The hinges 9 threadedly sleeved on both sides of the bidirectional screw rod 6 will move outward, and at the same time, drive the inner end of the transmission rod 10 to move together, so that the inner end of the transmission rod 10 rotates along the inside of the hinge 9, and the outer end of the transmission rod 10 rotates along the outer surface of the fixing bolt 11, and at the same time, a pulling force inward is applied to the fixing bolt 11, driving the fixing bolt 11 to move inward. At the same time, due to the rotatability of the universal wheel 13, the fixing bolt 11 can drive the first bed body 2 and the second bed body 3 to move in opposite directions, so that the first bed body 2 and the second bed body 3 begin to be unfolded. At the same time, the support legs 1 on the front and rear sides will respectively drive the limit plate 5 and the limit frame 4 along the outer surface of the bidirectional screw rod 6 The bed is then moved outwardly, and at the same time, the limiting plate 5 moves along the inside of the limiting frame 4. At the same time, due to the setting of the pressing strip 18, one side of the mattress and the sheet is fixed to the second bed body 3. Therefore, when the second bed body 3 starts to move, the mattress, the sheet and the patient lying on the sheet will be driven to move together. Therefore, the patient does not need to get out of bed during this process. When the first bed body 2 and the second bed body 3 are unfolded to a suitable width, the family members stop turning the hand crank 8. Because the bidirectional screw rod 6 and the hinge 9 are threadedly connected, they have a self-locking function. At this point, the widening of the bed is completed. Otherwise, it is stored. Subsequently, the accompanying family members can lie on the unfolded first bed body 2 to rest.
[0036] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
[0037] The sizes and shapes of all components in this structure are not specifically limited here and need to be produced according to actual conditions.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
