[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.
[0023] refer to Figure 1-Figure 6 The present invention proposes an article transport cart for neonatal resuscitation and first aid, including a bracket 1, a lifting device 2, a tray 3 and a storage component 4. The bracket 1 includes a bracket body 11 and a chassis 12. The bracket 1 is a frame structure of the article transport cart and has the function of carrying other components. The chassis 12 extends in the horizontal direction, and the bracket body 11 extends in the vertical direction. The chassis 12 is fixedly connected to the bottom of the bracket body 11. The chassis 12 can be formed as an integral part with the bracket body 11, so that the bracket 1 has a higher structural strength. A plurality of movable wheels are arranged under the chassis 12 to realize the movement of the article transport cart.
[0024] The lifting device 2 is slidably connected to the bracket body 11. The lifting device 2 slides in the vertical direction. The tray 3 is arranged in the horizontal direction and fixed to the lifting device 2. The tray 3 can carry items. When the lifting device 2 slides in the vertical direction, the tray 3 can be driven to slide, so that the items can be transported to the vicinity of shelves at different heights. A limiting member 31 is formed at the edge of one end of the tray 3 away from the lifting device 2. The limiting member 31 has a limiting effect on the items placed on the tray 3, which can prevent the items from falling off during transportation. The edge of the tray 3 can be formed with an upward flange portion, and the flange portion and the tray 3 define a storage space. The bottom of the limiting member 31 can form an open storage port, and the storage port is connected to the storage space.
[0025] The storage assembly 4 includes a storage plate 41, a control shaft sleeve 42 and a traction device 43. The control shaft sleeve 42 is slidably connected to the tray 3. The storage plate 41 is arranged in the horizontal direction and is rotatably connected to the control shaft sleeve 42. The traction device 43 is fixedly connected to the control shaft sleeve 42. By rotating the control shaft sleeve 42, the storage plate 41 can be moved to the tray 3, and the items can be placed on the storage plate 41. When the tray 3 carrying the items is transported to the vicinity of the shelf by the sliding lifting device 2, the control shaft sleeve 42 can be rotated to move the storage plate 41 to the shelf. At this time, the storage plate 41 is located on the side of the limiter 31 away from the lifting device 2 and the storage plate 41 is located between the shelf and the items. By operating the traction device 43, the storage plate 41 can be controlled to move in the direction close to the lifting device 2, for example, the storage plate 41 can enter the receiving space through the receiving port. As the storage plate 41 moves, the items will move with it. When the items contact the limiting member 31, the storage plate 41 can continue to enter the accommodating space from the accommodating opening. The items are firmly held in the existing position due to the abutment of the limiting member 31. When the storage plate 41 is completely pulled out from between the items and the shelf, the items can be placed on the shelf, thereby realizing the transfer of items from the item transport cart to the shelf.
[0026] The transfer process of the above-mentioned items does not require direct contact from the operator. For example, the operator does not need to push the items placed on the storage plate 41 onto the shelf. When the items need to be placed on a shelf at a higher position, a traction mechanism for controlling the traction device 43 can be set at a low position, and the operator can complete the operation of placing the items at a low position, so that the item transport cart has high convenience and reliability. At the same time, since the operator saves time in going to a higher shelf to manually place items, the transportation efficiency of the item transport cart is improved.
[0027] According to the article transport cart for neonatal resuscitation and first aid of the present invention, by providing a storage component 4 and forming a limiter 31 on the tray 3, the articles can be prevented from falling off during transportation. At the same time, when placing the articles, by moving the storage plate 41 carrying the articles onto the shelf, the limiter 31 abuts against the articles, and the operator can control the traction device 43 to withdraw the storage plate 41, so that the articles on the storage plate 41 can be conveniently and stably placed on the shelf at a higher position, which not only makes the article transport cart more convenient and reliable, but also improves the transportation efficiency of the article transport cart.
[0028] refer to Figure 2-Figure 8 According to some embodiments of the present invention, the control shaft set 42 includes a driving shaft 421, a first driven shaft 422a, a second driven shaft 422b, a third driven shaft 422c, a positioning shaft 423, a first transmission belt 424a, a second transmission belt 424b and a third transmission belt 424c. The driving shaft 421 is rotatably arranged at the lower part of the bracket body 11, and the operator can conveniently rotate the driving shaft 421 at a low place. The positioning shaft 423 is rotatably arranged at the top of the bracket body 11, the first driven shaft 422a is rotatably arranged between the driving shaft 421 and the positioning shaft 423 and is rotatably arranged on the lifting device 2, the driving shaft 421, the positioning shaft 423 and the first driven shaft 422a are linked by the first transmission belt 424a, wherein the distance between the driving shaft 421 and the positioning shaft 423 remains unchanged, the driving shaft 421 and the positioning shaft 423 can tighten the first transmission belt 424a, so that the driving shaft 421 can drive the first transmission belt 424a to move, as the lifting device 2 slides, the first driven shaft 422a can move between the driving shaft 421 and the positioning shaft 423, and as the driving shaft 421 rotates, the first transmission belt 424a can drive the first driven shaft 422a to rotate, and the first driven shaft 422a can rotate in the same direction as the driving shaft 421.
[0029] The second driven shaft 422b is slidably disposed on the tray 3, and the first driven shaft 422a and the second driven shaft 422b are linked by the second transmission belt 424b. Since the tray 3 is fixedly connected to the lifting device 2, the first driven shaft 422a can drive the second driven shaft 422b to rotate, and the second driven shaft 422b can rotate in the same direction as the first driven shaft 422a. The third driven shaft 422c is slidably disposed on the tray 3, and the second driven shaft 422b and the third driven shaft 422c are linked by the third transmission belt 424c. The second driven shaft 422b can drive the third driven shaft 422c to rotate, and the third driven shaft 422c can rotate in the same direction as the second driven shaft 422b, so that the second driven shaft 422b and the third driven shaft 422c can rotate in the same direction as the driving shaft 421. By setting up multiple driven shafts and transmission belts, the operator can control the movement of the storage plate 41 by rotating the driving shaft 421. When the lifting device 2 slides to a higher position, the operator can move the storage plate 41 by rotating the driving shaft 421 at a lower position, so that the items on the storage plate 41 can be conveniently and securely placed on a shelf at a higher position, which not only makes the item transport cart more convenient and reliable, but also improves the transportation efficiency of the item transport cart.
[0030] refer to Figure 2-Figure 8 According to some optional embodiments of the present invention, the control shaft sleeve 42 includes a first auxiliary shaft 425a, a second auxiliary shaft 425b, a first connecting shaft 426a and a second connecting shaft 426b, the first auxiliary shaft 425a and the second auxiliary shaft 425b are arranged in parallel at the bottom of the storage plate 41 and are fixedly connected to the storage plate 41, one end of the first connecting shaft 426a is fixedly connected to the second driven shaft 422b, and the other end of the first connecting shaft 426a is rotatably connected to the first auxiliary shaft 425a, one end of the second connecting shaft 426b is fixedly connected to the third driven shaft 422c, and the other end of the second connecting shaft 426b is rotatably connected to the second auxiliary shaft 425b. During the process of placing items, the first connecting shaft 426a and the second connecting shaft 426b rotate in the same direction through the second driven shaft 422b and the third driven shaft 422c, thereby driving the placement plate 41 on the tray 3 to move to the shelf. During this process, the placement plate 41 always remains horizontal, which can ensure the stable placement of items. The placement plate 41 located on the side of the limiter 31 away from the lifting device 2 can also be reset to the tray 3 by the reverse rotation of the driving shaft 421 to prepare for the placement of the next item.
[0031] refer to Figure 5Furthermore, the control shaft sleeve assembly 42 includes a support member 427, which is arranged between the second driven shaft 422b and the third driven shaft 422c. One end of the support member 427 is in sliding contact with the second driven shaft 422b, and the other end of the support member 427 is in sliding contact with the third driven shaft 422c. Through the cooperation between the support member 427 and the third transmission belt 424c, the second driven shaft 422b and the third driven shaft 422c are maintained at a fixed distance, thereby ensuring that the storage plate 41 always remains horizontal, thereby improving the stability of the item transport cart.
[0032] refer to Figure 6 According to some optional embodiments of the present invention, the length of the third driven shaft 422c is greater than the width of the storage plate 41, and the length of the second driven shaft 422b is greater than the length of the third driven shaft 422c. This design can avoid mutual interference between the storage plate 41, the third driven shaft 422c and the second driven shaft 422b during movement, thereby improving the stability of the item transport cart.
[0033] refer to Figure 1-Figure 6 According to some optional embodiments of the present invention, a sliding groove 32 is formed on the edge of the tray 3, and sliding protrusions 422d that cooperate with the sliding groove 32 are formed at both ends of the second driven shaft 422b and the third driven shaft 422c. This design can locate the sliding path of the second driven shaft 422b and the third driven shaft 422c, thereby improving the stability of the item transport cart.
[0034] refer to Figure 1-Figure 6According to some optional embodiments of the present invention, the traction device 43 includes a traction rope 431, a restoring spring 432, a restoring block 433 and a traction switch, the restoring block 433 is formed on the tray 3, and the restoring block 433 is arranged between the first driven shaft 422a and the second driven shaft 422b, the restoring spring 432 abuts between the restoring block 433 and the second driven shaft 422b, the traction mechanism is arranged at the lower part of the bracket body 11, the traction rope 431 connects the second driven shaft 422b and the traction mechanism, and the middle part of the traction rope 431 is laid on the first driven shaft 422a. The second driven shaft 422b and the third driven shaft 422c can be arranged in the accommodating space. When the storage plate 41 is moved to the shelf, the second driven shaft 422b, the third driven shaft 422c and the storage plate 41 are on the same horizontal plane. The operator can control the traction mechanism to pull the traction rope 431, so that the second driven shaft 422b and the third driven shaft slide toward the direction close to the lifting device 2, thereby driving the storage plate 41 to enter the storage space from the accommodating opening, so that the operator can control the traction mechanism arranged at a lower position to pull the storage plate 41 away from the items and the shelf, so as to place the items on the shelf. Especially when the items need to be placed on a shelf at a higher position, the operation can be completed by controlling the traction mechanism arranged at a lower position, which not only makes the item transport cart have higher convenience and reliability, but also improves the transportation efficiency of the item transport cart. On the other hand, after placing the items, the item transport cart is moved to a position away from the shelf, and the traction switch is operated again to release the traction rope 431. At this time, the third driven shaft 422c slides in the direction away from the lifting device 2 due to the elastic force of the return spring 432. During the sliding process, the third driven shaft 422c is constrained by the second transmission belt 424b, and the second transmission belt 424b is tightened and stops sliding, thereby realizing the position restoration of the third driven shaft 422c and the second driven shaft 422b maintained at a fixed distance therefrom. At this time, through the reverse rotation of the driving shaft 421, the storage plate 41 located on the side of the limit member 31 away from the lifting device 2 can be reset to the tray 3 to prepare for placing the next item.

The clutch switch drives the active shaft 421 and the clutch shaft 428 to rotate to the first position or the second position. When in the first position, the active shaft 421 and the clutch shaft 428 are arranged in the vertical direction and the active shaft 421 is located below the clutch shaft 428. At this time, the first driven shaft 422a is in contact with the first transmission belt 424a. When in the second position, the active shaft 421 and the clutch shaft 428 are in contact with the first transmission belt 424a. The shaft 421 and the clutch shaft 428 are arranged in the horizontal direction. At this time, the first driven shaft 422a is separated from the first transmission belt 424a. When the lifting device 2 slides, the clutch switch can be controlled to drive the active shaft 421 and the clutch shaft 428 to rotate to the second position, thereby preventing the first driven shaft 422a that moves relative to the first transmission belt 424a from rotating and preventing the objects from shaking. When the lifting device 2 is fixed, the clutch switch can be controlled to drive the active shaft 421 and the clutch shaft 428 to rotate to the first position, so that the first transmission belt 424a can drive the first driven shaft 422a to rotate. The above design improves the stability of the structure of the object transport cart.
[0036] refer to Figure 1 According to some embodiments of the present invention, the lifting device 2 is mounted on the bracket body 11, and the lifting device 2 includes a gear and a motor. The bracket body 11 is provided with a rack that cooperates with the gear. The rack can extend in the vertical direction. The motor drives the gear to rotate, driving the lifting device 2 to slide, so that the lifting device 2 drives the tray 3 to move up and down in the vertical direction.
[0037] refer to Figure 1-Figure 6 According to some embodiments of the present invention, the surface of the limiting member 31 close to the lifting device 2 is formed as a concave arc surface. This design can prevent the limiting member 31 from interfering with the storage plate 41 when the storage plate 41 moves, thereby improving the reliability of the item transport cart.
