Description

Technical Field

[0001] This utility model belongs to the field of hospital bed design technology, and specifically relates to a multifunctional hospital bed dining board. Background Technology

[0002] A hospital bed generally refers to a nursing bed, which is designed according to the patient's treatment needs and bedridden lifestyle. It is designed to allow family members to accompany the patient, has multiple nursing functions and operation buttons, and is an insulated and safe bed. In order to facilitate the patient to eat in the hospital bed, the hospital bed needs to be equipped with a dining board, which is placed on the upper side of the bed rails so that the patient can eat on the dining board.

[0003] Currently, Chinese patent publication number CN107647989A, published on February 2, 2018, discloses a hospital bed equipped with a dining board. The bed frame is equipped with a dining board that can be placed and used through the side rails. The dining board is hooked to the side rails by retractable hook grooves on both sides. A hook is provided on one side of the dining board that can be hooked into the headboard slot when not in use.

[0004] When using the dining board, the board surface can only be in a horizontal position between the guardrails. When patients need to read books or use electronic devices, they can only place the books and electronic devices flat on the dining board. At this time, the patients will be in a downward position for a long time, which will eventually affect the patients' cervical spine. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional bedside dining board that can adjust the angle of the board according to the patient's needs.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multifunctional hospital bed dining board, comprising a board body, a first card plate located at one end of the board body and used for supporting on a guardrail, and a second card plate located at the other end of the board body and used for supporting on a guardrail. A first connecting platform is provided on the lower surface of one end of the board body, and a first shaft hole is opened in the first connecting platform. A first connecting ear is provided on the first card plate, and a first rotating shaft for passing through the first shaft hole is provided on the first connecting ear. A second connecting platform is provided on the lower surface of the board body away from the first connecting platform, and a second shaft hole is opened in the second connecting platform. A second connecting ear is provided on the second card plate, and a second rotating shaft for passing through the second shaft hole is provided on the second connecting ear. A toothed post is provided on the second rotating shaft, and a toothed groove for the toothed post to be embedded is opened in the end of the second shaft hole. A baffle for tilting and supporting books or electronic devices is provided on the side of the upper surface of the board body.

[0007] A further feature of this invention is that: a positioning ring groove is provided at the bottom of both the first shaft hole and the second shaft hole; a return spring is fixed at the end of both the first rotating shaft and the second rotating shaft; and a positioning disc embedded in the positioning ring groove is fixed at the end of the return spring.

[0008] A further feature of this invention is that the cross-section of the baffle is L-shaped.

[0009] A further feature of this invention is that a reinforcing column is slidably connected to the side of the plate near the end of the second card plate, and a card is provided on the side wall of the end of the second card plate for the end of the reinforcing column to be embedded.

[0010] A further feature of this invention is that: a connecting hole for embedding a reinforcing column is provided on the plate body, a waist-shaped hole communicating with the connecting hole is provided on the side of the plate body, and a push rod passing through the waist-shaped hole is provided on the side of the reinforcing column.

[0011] A further feature of this invention is that a connecting spring is provided inside the connecting hole, with one end connected to the bottom wall of the connecting hole and the other end connected to the end face of the reinforcing column.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. When a patient needs to read a book on the board, the board is first supported between the side rails of the hospital bed by the first and second clamping plates. Then, the board is moved away from the second clamping plate, so that the toothed column disengages from the toothed groove. The board can then rotate around the first and second pivots. When the board is rotated to the angle required by the patient, it is moved closer to the second clamping plate, so that the toothed column is re-embedded in the toothed groove. At this time, the angle of rotation of the board can be positioned by the engagement of the toothed column and the toothed groove, and the book can be supported on the baffle. Finally, the angle of the board can be adjusted according to the patient's needs.

[0014] 2. One end of the return spring is connected to the positioning plate and the other end is connected to the end of the first or second rotating shaft, and the positioning plate is embedded in the positioning ring groove. At this time, the first card plate, the plate body and the second card plate can be connected by the return spring. At the same time, the tensile deformation capacity of the return spring can also adjust the distance between the first card plate and the second card plate, so that the dining board can be adapted to guardrails of different widths.

[0015] 3. The L-shaped cross-section of the baffle provides stable support for books or electronic devices. Additionally, when the dining board needs to be stored on the footboard of the hospital bed, the L-shaped baffle can be hung on the footboard, thus enabling the baffle to be used for two purposes.

[0016] 4. When the plate is in a horizontal position, the end of the reinforcing column is embedded in the slot, and the horizontal plate can be supported by the reinforcing column, which helps the plate to remain stable in a horizontal state.

[0017] 5. The reinforcing column is inserted through the connecting holes, thereby achieving a sliding connection of the reinforcing column at the side of the plate. At the same time, the reinforcing column can be moved back and forth by the push rod.

[0018] 6. By connecting one end of the connecting spring to the bottom wall of the connecting hole and the other end to the end face of the reinforcing column, the elastic restoring force of the connecting spring can ensure that the end of the reinforcing column is stably embedded in the slot.

[0029] Principle: When a patient needs to read a book on the board 1, the board 1 is first supported between the side rails of the hospital bed by the first clamping plate 2 and the second clamping plate 3. Then, the board 1 is moved away from the second clamping plate 3, so that the toothed post 312 is dislodged from the toothed groove 122 and the end of the reinforcing post 6 is moved out of the groove 32. At the same time, the return spring 5 undergoes elastic deformation. Then, the board 1 can rotate around the first rotating shaft 211 and the second rotating shaft 311. When the board 1 rotates to the angle required by the patient, the elastic restoring force of the return spring 5 will allow the board 1 to return to the side closer to the second clamping plate 3, so that the toothed post 312 is re-embedded in the toothed groove 122. At this time, the angle of rotation of the board 1 can be positioned by the engagement of the toothed post 312 and the toothed groove 122, and the book can be supported on the baffle 13. Finally, the angle of the board 1 can be adjusted according to the patient's needs.
