Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an extendable medical bed. Background Art

[0002] Medical beds are mainly used by patients in their daily lives in hospitals. They are designed based on the patients' bedridden habits and treatment needs. They are mainly practical and simple, convenient for medical observation and inspection and family members to operate and use. They are the most basic daily care appliances needed by patients.

[0003] However, in daily use, because the area of the hospital bed is small, the patient's family members can only choose to lie in front of the bed to rest in order to provide timely care for the patient at night. This makes it difficult for the patient's family members to get a relatively good rest environment, so there is an urgent need for an extendable medical bed. Utility Model Content

[0004] The purpose of the utility model is to provide an extendable medical bed that can increase the bed area and can be freely adjusted.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An extendable medical bed, comprising:

[0007] base plate;

[0008] Two connecting plates are symmetrically arranged on both sides of the base plate;

[0009] The extension plate is provided with a guide hole through the connecting plate so that the extension plate slides in the guide hole;

[0010] A plurality of groups of fixing members are fixed to the bottom surface of the extension plate, each group including two first fixing plates and a rotating shaft, and the rotating shaft is arranged between the two first fixing plates;

[0011] A support rod, one end of which rotates on the rotating shaft and the other end is set in a hole set on the side of the bottom plate;

[0012] The elastic telescopic rod has a fixed end fixed to the rod of the support rod, and the telescopic end contacts the inner side of the extension plate. When the support rod rotates, the elastic telescopic rod rotates around the axis of the rotating shaft and rotates into the limiting hole set in the first fixed plate;

[0013] The threaded cylinder is arranged on the surface of the bottom plate, and its two ends are respectively fixed to the inner side of the connecting plate;

[0014] A second fixing plate is provided on the bottom surface of the extension plate;

[0015] a threaded rod, one end of which is disposed in the threaded barrel and the other end of which extends outward from the second fixing plate;

[0016] The knob and the extended end of the threaded rod are fixedly connected to the knob. By rotating the knob, the threaded rod moves toward the outside of the threaded barrel and drives the extension plate to move together.

[0017] Furthermore, a limiting groove is provided on the inner side of the first fixing plate along the trajectory of movement of the telescopic end of the elastic telescopic rod, and a limiting hole is provided in the limiting groove.

[0018] Furthermore, a plurality of baffles are provided on the outer side of the extension plate, and the baffles are fixed together with the extension plate through a fixing assembly.

[0019] Furthermore, the fixing assembly includes: a fixing block, which is fixed on the upper surface of the extension plate, and the fixing block and the baffle are connected by a threaded pin, and the end of the threaded pin away from the baffle extends outward from the fixing block, and a rubber knob is provided at the extension end, and a gasket is provided between the rubber knob and the fixing block.

[0020] Furthermore, a plurality of sleeves are provided on opposite sides of the bottom plate and the extension plate, and the positions of the sleeves correspond to the fixing members and are used to accommodate the support rods.

[0021] Furthermore, tail plates are fixed on the other two opposite sides of the base plate.

[0022] Furthermore, a roller is provided at the bottom of the base plate via a connecting rod.

[0023] Furthermore, two layers of mattresses are provided on the upper surface of the bottom plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The utility model is based on a base plate, and by symmetrically arranging two connecting plates on both sides thereof, the extension plate can slide in the guide hole set in the connecting plate, and then a fixing part and a second fixing plate are respectively provided at the bottom of the extension plate. The former enables the support rod used to support the extension plate to rotate along the rotating shaft through the two fixing plates and the rotating shaft, and the latter cooperates with the threaded cylinder set on the surface of the base plate through the threaded rod, so that the extension plate will not separate from the base plate when extending outward, and when extending outward, the support rod also moves outward at the same time. When the support rod separates from the base plate, the support rod moves downward under gravity, and the elastic telescopic rod set on the rod moves together. When the support rod is perpendicular to the horizontal plane, the telescopic end of the elastic telescopic rod is telescoped into the limiting hole of the first fixed plate. Through such a structure, the area of the bed is increased. At the same time, because of its simple operation and freedom of adjustment, the practical experience of the patient's family is improved.

[0033] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0034] See also Figure 1-Figure 5 In this embodiment, the base plate 1 includes: a base plate 1, connecting plates 4 are respectively provided on the sides where the long sides of the base plate 1 are located, the connecting plates 4 are provided with guide holes for accommodating the extension plates 61 included in the extension assembly 6, and the extension plates 61 pass through the guide holes;

[0035] It should be noted that the base plate 1 is rectangular and has two symmetry axes, namely a vertical symmetry axis perpendicular to the bottom edge and a horizontal symmetry axis parallel to the bottom edge;

[0036] Specifically, the guide hole, on the one hand, serves to enable the extension plate 61 to move back and forth along the direction of the hole, and on the other hand, serves to support the extension plate 61;

[0037] The extension assembly 6 further includes: four fixing members, which are arranged along the vertical symmetry axis of the base plate 1, with two fixing members provided on the left and right sides of the bottom surface of the extension plate 61;

[0038] It should be noted that the fixing member includes two first fixing plates 64 and a rotating shaft 65. The rotating shaft 65 is arranged between the two first fixing plates 64. A support rod 63 is passed through the rotating shaft 65. The end of the support rod 63 away from the rotating shaft 65 is arranged in a sleeve 10 on both sides of the base plate 1 opposite to the extension plate 61.

[0039] Specifically, when the extension plate 61 is not extended outward, the support rod 63 is always limited by the sleeve 10 so that its direction is always parallel to the horizontal symmetry axis;

[0040] The fixing member also includes an elastic telescopic rod 66;

[0041] It should be noted that the fixed end of the elastic telescopic rod 66 is fixed to the support rod 63, and the telescopic end is in contact with the inner side of the first fixed plate 64;

[0042] Specifically, when the support rod 63 is still limited by the sleeve 10, the position of the elastic telescopic rod 66 remains unchanged and is in a compressed state; when the support rod 63 is released from the limit of the sleeve 10, the elastic telescopic rod 66 rotates around the axis of the rotating shaft 65 until it rotates into the limit hole 641 provided on the path. At this time, the telescopic end of the elastic telescopic rod 66 is not limited by the first fixing plate 64, so the telescopic end extends, so that the telescopic clamp is engaged in the limit hole 641, and the support rod 63 is stably supported on the ground.

[0043] Along the horizontal symmetry axis of the bottom plate 1, a threaded barrel 11 is fixed on its surface. Both ends of the threaded barrel 11 are fixed to the inner side of the connecting plate 4. In conjunction with this, a second fixing plate 67 is provided on the bottom surface of the extension plate 61 and at a corresponding position. A threaded rod 62 is provided between the second fixing plate 67 and the threaded barrel 61. One end of the threaded rod 62 is provided in the threaded barrel 11, and the other end extends to the outside of the second fixing plate 67. The extended end is fixed to the knob 60.

[0044] Specifically, by turning the knob 60, the threaded rod 62 moves toward the outside of the threaded cylinder 11, and drives the extension plate 61 to move together;

[0045] It should be noted that a portion of the threaded rod 62 is always inside the threaded barrel 11 , which can ensure that the extension plate 61 will not separate from the base plate.

[0046] In this embodiment, a limiting groove 640 is opened on the inner side of the first fixing plate 64 along the trajectory of the telescopic end of the elastic telescopic rod 66 , and a limiting hole 641 is set in the limiting groove 640 .

[0047] In this embodiment, a plurality of baffles 7 are provided on the outer side of the extension plate 61 , and the baffles 7 are fixed to the extension plate 61 via a fixing assembly 8 .

[0048] See also Figure 6 In this embodiment, the fixing assembly 8 includes: a fixing block 80, which is fixed to the upper surface of the extension plate 61. The fixing block 80 and the baffle 7 are connected by a threaded pin 83. The end of the threaded pin 83 away from the baffle 7 extends outward from the fixing block 80. The extended end is provided with a rubber knob 82. A washer 81 is provided between the rubber knob 82 and the fixing block 80.

[0049] It should be noted that the rubber knob 82 is sleeved on one end of the threaded pin 83, which can shield the threaded pin 83 and prevent the patient or family members from bumping into the threaded pin 83 and causing damage.

[0050] In this embodiment, tail plates 3 are fixed on the other two opposite sides of the base plate 1 .

[0051] In this embodiment, a roller 2 is provided at the bottom of the base plate 1 via a connecting rod;

[0052] It should be noted that the roller 2 is a universal wheel.

[0053] In this embodiment, two layers of mattresses 5 are provided on the upper surface of the base plate 1;

[0054] It should be noted that the upper mattress 5 is composed of two parts, and the area thereof is the same as the area of the extension plate 61 after extension. After extension, the two parts are placed on the two extension plates 61 respectively.

[0055] Working principle:

[0056] When the bed needs to be extended, the knob 60 is turned, and the threaded rod 62 moves toward the outside of the threaded cylinder 11. At this time, the extension plate 61 moves outward together, and drives the support rod 63 to move away from the sleeve 10. When the extension plate 61 is adjusted to the maximum area, the support rod 63 is separated from the limit of the sleeve 10 and moves downward around the rotating shaft 65 under the force of gravity, and the elastic telescopic rod 66 rotates with the axis of the rotating shaft 65 as the center of the circle. When the telescopic end of the elastic telescopic rod 66 reaches the end of the limiting groove 640, the telescopic end is extended because the limiting hole 641 is provided at the end. The extended part is engaged in the limiting hole 641, so that the support rod 63 is stably supported on the ground.

[0057] When the extension plate 61 needs to be retracted, the telescopic end in the limiting hole is compressed by an external tool, and at the same time, the support rod 63 is rotated to make the elastic telescopic rod 66 return to the compressed state when it contacts the limiting groove 640. Then, by twisting the knob 60 in the opposite direction, the threaded rod 62 moves toward the inside of the threaded tube 11. At this time, the extension plate 61 moves inward together, and drives the support rod 63 to move toward the direction close to the sleeve 10 until the extension plate 61 returns to its original state.

[0058] When it is necessary to add a baffle 7 to the side, align the threaded pin 83 with the washer 81 with the hole and insert it into the fixing block 80. When the threaded pin 83 reaches the baffle 7, rotate the rubber knob 82. The rubber knob 82 drives the threaded pin 83 to be screwed into the threaded hole set in the baffle 7 until the baffle 7 is firmly fixed to the side of the extension plate 61. At the same time, because the rubber knob 82 faces the user, the rubber material is used to block it, preventing the patient or family members from bumping into the threaded pin 83 and causing damage.

[0059] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
