Description

Technical Field

[0001] This utility model relates to the field of mobile bed-transfer dining cart technology, and in particular to a limiting protection structure for a mobile bed-transfer dining cart. Background Technology

[0002] During the recuperation and rehabilitation process, some bedridden patients find it difficult or cumbersome to get out of bed. Moving the mobile dining table above the bed allows patients to sit on the bed and eat. Therefore, the mobile dining table is widely used in the recuperation and rehabilitation process for bedridden patients.

[0003] During the use of mobile dining carts, most of the tabletops are flat and there are no limiting or protective structures around them. When the table is moved, the food placed on the tabletop is prone to tipping over and falling, affecting the usability.

[0004] Therefore, to address the aforementioned issues of inconvenience in providing limiting protection and convenient storage for the dining cart, a limiting protection structure for the mobile bed-mounted dining cart can be designed. During the use of the mobile bed-mounted dining cart, multiple components work together to achieve the unfolding and locking functions of the protective side panels and protective end panels. At the same time, the protective mechanism can be conveniently stored, thus improving the safety and stability of the dining cart. Utility Model Content

[0005] In order to overcome the problem that traditional mobile bed-transfer meal carts often have limited functions and cannot meet the diverse needs of bedridden patients, resulting in unsatisfactory usage, improvements are urgently needed. Furthermore, there are issues with limiting the movement of the meal cart and making it difficult to store it conveniently.

[0006] The technical solution of this utility model is as follows: a mobile dining cart limiting protection structure, including a mobile cart body, a fixed dining table, a storage slot, a protective side plate, an adjusting shaft, an adjusting wheel, a positioning rod, a limiting slot, a protective end plate, a rotating shaft, a locking ratchet, a locking slot, a guide frame, and a locking rod; a fixed dining table is fixedly installed at the upper end of the mobile cart body, and two sets of storage slots are opened on both sides of the bottom wall of the fixed dining table. Two sets of protective side plates are installed on both sides of the fixed dining table. An adjusting shaft is fixedly installed inside the lower end of the protective side plate, an adjusting wheel is fixedly installed at one end of the adjusting shaft, a positioning rod is installed inside the upper end of the adjusting wheel, a limiting slot is opened on the inner wall of the protective side plate, two sets of protective end plates are installed above the rear end of the fixed dining table, a rotating shaft is fixedly installed inside one end of the protective end plate, a locking ratchet is fixedly installed on the upper side wall of the rotating shaft, a locking slot is opened on the inner wall of the rear end of the protective side plate, a guide frame is fixedly installed inside the locking slot, and a locking rod is installed inside the guide frame.

[0007] Preferably, during the use of the mobile dining cart, firstly, pulling the positioning rod outward unlocks the adjusting wheel. Then, rotating the adjusting wheel causes the protective side plate to rotate and unfold via the adjusting shaft. When the protective side plate rotates to a perpendicular position to the fixed dining table, releasing the positioning rod allows one end of the positioning rod to reset and insert into the side wall of the fixed dining table, locking the adjusting wheel and the protective side plate. This provides a limiting and protective effect on both sides of the fixed dining table. Furthermore, rotating one end of the protective end plate allows it to rotate around the rotating shaft. During this process, the rotating shaft drives the locking ratchet to rotate, and the elastic action then drives one end of the locking rod. The material slides down the arc surface of the locking ratchet to the inner wall of the lower tooth groove, ensuring it remains in close contact with the inner wall of the locking ratchet's tooth groove. This locks the locking ratchet and the protective end plate. When the protective end plate rotates to a perpendicular position to the protective side plate, it unfolds, thus providing a limiting protection effect on the rear end of the fixed dining table. When retracting the protective end plate and side plate, the operation is reversed. In summary, this mobile dining cart limiting protection structure, through the cooperation of multiple components, achieves the unfolding and locking functions of the protective side plate and end plate, while also providing convenient storage of the protective mechanism. This structure not only improves the safety and stability of the dining cart but also facilitates user operation.

[0008] Preferably, both ends of the adjusting shaft are rotatably connected to the inner walls of the storage groove, both ends of the rotating shaft are rotatably connected to the inner walls of the limiting groove, and the positioning rod is slidably connected to the adjusting wheel.

[0009] Preferably, the locking rod is located inside the locking groove, and the locking rod is slidably connected to the guide frame. One end of the locking rod abuts against the inner wall of the tooth groove of the locking ratchet.

[0010] Preferably, the front side wall of the fixed dining table has multiple sets of positioning holes, one end of the positioning rod is engaged with the inside of the positioning hole, and the other end of the positioning rod is fixedly provided with a positioning ring.

[0011] Preferably, a positioning spring is provided on the inner wall of the positioning ring, with one end of the positioning spring fixedly connected to the inner wall of the positioning ring and the other end of the positioning spring fixedly connected to the side wall of the adjusting wheel.

[0012] Preferably, a toggle lever is fixedly provided at the other end of the locking lever, and a limit ring is fixedly provided on the side wall of one end of the locking lever, with a limit spring provided on the inner wall of the limit ring.

[0013] Preferably, one end of the limiting spring is fixedly connected to the inner wall of the limiting ring, and the other end of the limiting spring is fixedly connected to the inner wall of the guide frame.

[0014] The beneficial effects of this utility model are:

[0015] When using the mobile dining cart, first, pull the positioning rod outward to unlock the adjusting wheel. Then, rotate the adjusting wheel to rotate and unfold the protective side plate via the adjusting shaft. When the protective side plate rotates to a perpendicular position to the fixed dining table, release the positioning rod. Under the elastic action, one end of the positioning rod will return to its original position and insert into the side wall of the fixed dining table, locking the adjusting wheel and the protective side plate. This provides a limiting and protective effect on both sides of the fixed dining table. Furthermore, rotating one end of the protective end plate allows it to rotate in a circle around the rotating shaft. During this process, the rotating shaft drives the locking ratchet to rotate, and under the elastic action, it drives one end of the locking rod along... The curved surface of the locking ratchet slides down to the inner wall of the lower tooth groove, ensuring it remains in close contact with the inner wall of the locking ratchet's tooth groove. This locks the locking ratchet and the protective end plate. When the protective end plate rotates to a perpendicular position to the protective side plate, it unfolds, thus providing a limiting protection effect on the rear end of the fixed dining table. When retracting the protective end plate and side plate, the operation is reversed. In summary, this mobile dining cart limiting protection structure, through the cooperation of multiple components, achieves the unfolding and locking functions of the protective side plate and end plate, while also providing convenient storage for the protective mechanism. This structure not only improves the safety and stability of the dining cart but also facilitates user operation. Attached Figure Description

[0024] Please see Figure 1 and Figure 6 This utility model provides an embodiment: a mobile bed-crossing dining cart limiting protection structure, including a mobile cart body 1, a fixed dining table 2, a storage slot 3, a protective side plate 4, an adjusting shaft 5, an adjusting wheel 6, a positioning rod 7, a limiting slot 8, a protective end plate 9, a rotating shaft 10, a locking ratchet 11, a locking slot 12, a guide frame 13, and a locking rod 14; the fixed dining table 2 is fixedly installed at the upper end of the mobile cart body 1, and two sets of storage slots 3 are opened on both sides of the bottom wall of the fixed dining table 2. Two sets of protective side plates 4 are provided on both sides of the fixed dining table 2, and the lower end of the protective side plate 4 is inwardly... An adjusting shaft 5 is fixedly installed on the part, and an adjusting wheel 6 is fixedly installed on one end of the adjusting shaft 5. A positioning rod 7 is installed inside the upper end of the adjusting wheel 6. A limit groove 8 is opened on the inner wall of the protective side plate 4. Two sets of protective end plates 9 are installed above the rear end of the fixed dining table 2. A rotating shaft 10 is fixedly installed inside one end of the protective end plate 9. A locking ratchet 11 is fixedly installed on the upper side wall of the rotating shaft 10. A locking groove 12 is opened on the inner wall of the rear end of the protective side plate 4. A guide frame 13 is fixedly installed inside the locking groove 12. A locking rod 14 is installed inside the guide frame 13.

[0025] Please see Figure 3 and Figure 5Both ends of the adjusting shaft 5 are rotatably connected to the inner walls of the storage groove 3, and both ends of the rotating shaft 10 are rotatably connected to the inner walls of the limiting groove 8. The positioning rod 7 is slidably connected to the adjusting wheel 6. Rotating the adjusting wheel 6 allows the protective side plate 4 to rotate and unfold via the adjusting shaft 5. In addition, rotating one end of the protective end plate 9 allows it to rotate and unfold around the rotating shaft 10. The locking rod 14 is located inside the locking groove 12 and is slidably connected to the guide frame 13. One end of the locking rod 14 abuts against the inner wall of the tooth groove of the locking ratchet 11. Under the elastic action, one end of the locking rod 14 can slide down along the arc surface of the locking ratchet 11 to the inner wall of the lower tooth groove, so that it can always be in close contact with the inner wall of the tooth groove of the locking ratchet 11, thereby locking the locking ratchet 11 and the protective end plate 9. The front side wall of the fixed dining table 2 is provided with multiple sets of positioning holes 15. One end of the positioning rod 7 is engaged with the inside of the positioning hole 15, and the other end of the positioning rod 7 is fixedly provided with a positioning ring 16. One end of the positioning rod 7 is reset and inserted into the inside of the corresponding positioning hole 15, thereby locking the adjusting wheel 6 and the protective side plate 4.

[0026] Please see Figure 2 and Figure 4 A positioning spring 17 is provided on the inner wall of the positioning ring 16. One end of the positioning spring 17 is fixedly connected to the inner wall of the positioning ring 16, and the other end of the positioning spring 17 is fixedly connected to the side wall of the adjusting wheel 6. Under the elastic action of the positioning spring 17, one end of the positioning rod 7 can be driven to reset and insert into the corresponding positioning hole 15, so that the adjusting wheel 6 and the protective side plate 4 are locked. A toggle rod 18 is fixedly provided on the other end of the locking rod 14, and a limit ring 19 is fixedly provided on the side wall of one end of the locking rod 14. A limit ring 19 is provided on the inner wall of the limit ring 19. The positioning spring 20; pushing one end of the actuating lever 18 backward will cause one end of the locking lever 14 to disengage from the inner wall of the tooth groove of the locking ratchet 11, thereby unlocking the locking ratchet 11 and the protective end plate 9; one end of the limiting spring 20 is fixedly connected to the inner wall of the limiting ring 19, and the other end of the limiting spring 20 is fixedly connected to the inner wall of the guide frame 13; under the elastic action of the limiting spring 20, one end of the locking lever 14 is inserted into the corresponding tooth groove of the locking ratchet 11 for close contact, thereby locking the locking ratchet 11 and the protective end plate 9.

[0027] When the mobile dining cart is in use, firstly, pull the positioning rod 7 outward so that one end of it disengages from the positioning hole 15, thereby unlocking the adjusting wheel 6. Then, rotate the adjusting wheel 6, which will drive the protective side plate 4 to rotate and unfold through the adjusting shaft 5. When the protective side plate 4 rotates to a position perpendicular to the fixed dining table 2, release the positioning rod 7. Under the elastic action of the positioning spring 17, one end of the positioning rod 7 can be reset and inserted into the corresponding positioning hole 15, thereby locking the adjusting wheel 6 and the protective side plate 4. Furthermore, according to the above operation, the other set of protective side plates 4 can be rotated and unfolded, thereby achieving the effect of limiting and protecting both sides of the fixed dining table 2.

[0028] Furthermore, by rotating one end of the protective end plate 9, it can be made to expand in a circle around the rotating shaft 10. During this process, the rotating shaft 10 can drive the locking ratchet 11 to rotate, and under the elastic action of the limiting spring 20, one end of the locking rod 14 can slide down along the arc surface of the locking ratchet 11 to the inner wall of the lower tooth groove, so that it can always be in close contact with the inner wall of the tooth groove of the locking ratchet 11, so that the locking ratchet 11 and the protective end plate 9 are locked. When the protective end plate 9 is rotated to a position perpendicular to the protective side plate 4, the protective end plate 9 can be expanded. In addition, according to the above operation, the other set of protective end plates 9 can be rotated and expanded, thereby achieving the effect of limiting protection for the rear end of the fixed dining table 2.

[0029] When the protective end plate 9 is being stored, firstly, push one end of the lever 18 backward, which will cause one end of the locking lever 14 to disengage from the inner wall of the tooth groove of the locking ratchet 11, thus unlocking the locking ratchet 11 and the protective end plate 9. Then, one end of the protective end plate 9 can be reversed to rotate into the interior of the limiting groove 8 to achieve the effect of folding and storage. Subsequently, release the lever 18, and under the elastic action of the limiting spring 20, one end of the locking lever 14 will be inserted into the corresponding tooth groove of the locking ratchet 11 for close contact, thus locking the locking ratchet 11 and the protective end plate 9.

[0030] When the protective side plate 4 is stored, firstly, pull the positioning rod 7 outward so that one end of it is disengaged from the inside of the positioning hole 15. Then, reverse the protective side plate 4 so that it rotates into the inside of the storage slot 3 to achieve the effect of folding and storing. Subsequently, release the positioning rod 7. Under the elastic action of the positioning spring 17, one end of it is reset and inserted into the inside of the corresponding positioning hole 15, so that the adjusting wheel 6 and the protective side plate 4 are locked.

[0031] In summary, this mobile bed-crossing dining cart limit protection structure, through the cooperation of multiple sets of components, realizes the unfolding and locking functions of the protective side plate 4 and the protective end plate 9. At the same time, it realizes the convenient storage function of the protective mechanism. This structure not only improves the safety and stability of the dining cart, but also facilitates the user's use and operation.

[0032] Through the above steps, when the mobile dining cart is in use, firstly, pull the positioning rod 7 outward to unlock the adjusting wheel 6. Then, rotate the adjusting wheel 6, which will cause the protective side plate 4 to rotate and unfold via the adjusting shaft 5. When the protective side plate 4 rotates to a position perpendicular to the fixed dining table 2, release the positioning rod 7. Under the elastic action, one end of the positioning rod 7 can be reset and inserted into the side wall of the fixed dining table 2, causing the adjusting wheel 6 and the protective side plate 4 to lock. This achieves the effect of limiting and protecting both sides of the fixed dining table 2. In addition, rotating one end of the protective end plate 9 will cause it to rotate around the rotating shaft 10. During this process, the rotating shaft 10 can drive the locking ratchet 11 to rotate, and under the elastic action, it can drive the locking rod. One end of 14 slides down along the arc surface of the locking ratchet 11 to the inner wall of the lower gear groove, thus ensuring that it always keeps in close contact with the inner wall of the locking ratchet 11 gear groove, thereby locking the locking ratchet 11 and the protective end plate 9. When the protective end plate 9 rotates to a position perpendicular to the protective side plate 4, the protective end plate 9 can be unfolded, thereby achieving the effect of limiting protection for the rear end of the fixed dining table 2. When the protective end plate 9 and the protective side plate 4 are to be stored, the operation is reversed according to the above operation. In summary, this mobile bed-crossing dining cart limiting protection structure realizes the unfolding and locking functions of the protective side plate 4 and the protective end plate 9 through the cooperation of multiple sets of components. At the same time, it realizes the convenient storage function of the protective mechanism. This structure not only improves the safety and stability of the dining cart, but also facilitates the use and operation of the user.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
