Description

Technical Field

[0001] The utility model relates to the technical field of medical flat carts, in particular to a flat cart for cardiovascular medicine. Background Art

[0002] In the medical rescue of cardiovascular medicine department, due to the frequent emergencies, the medical rescue work is busy and intense, with a fast pace and high work intensity, which is a common problem in many hospitals. Among the patients who need emergency rescue, some seriously ill patients are assisted in transportation by stretcher carts (flat carts).

[0003] Some medical flatbed carts currently on the market are not equipped with armrests, which requires bending over when pushing, resulting in average comfort during the pushing process. In order to facilitate pushing, some flatbed carts are equipped with armrests at one end, but these armrests easily block the carrying and gripping parts of the stretcher on the flatbed cart, which affects the placement and transportation of the stretcher, resulting in average convenience. Moreover, some flatbed carts have stretchers that are not fixed to the frame, so the stability of the stretcher is average when moving, which brings considerable trouble to the transportation work. Some flatbed carts fix the stretcher to the frame through fixed structures, but these fixed structures also need to be locked and unlocked separately, which not only increases the amount of operation for the user, but is also not suitable for use in emergency situations. Therefore, there is still room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0036] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0037] The utility model provides Figures 1 to 6 The first embodiment of the flat cart for cardiovascular medicine shown in the figure comprises a square frame 1 and a stretcher 5. The lower part of the frame 1 is provided with a support leg 2, the lower end of the support leg 2 is provided with a running wheel 3, and a support frame is provided between the support leg 2 and the frame 1. A connecting shaft 6 is provided on one side of the frame 1, and a door-shaped handrail 4 is inserted and slidably connected to the connecting shaft 6. A connecting assembly 7 is provided between the handrail 4 and the support leg 2.

[0038] The connecting assembly 7 includes a limiting member 701 and a supporting member 702. The limiting member 701 is provided at the end of the armrest 4. The supporting member 702 is fixedly connected to the outer surface of the supporting leg 2, and the limiting member 701 abuts against the upper surface of the supporting member 702.

[0039] The lower edge of the stretcher 5 is fixedly connected with a plurality of positioning blocks 10, and the plurality of positioning blocks 10 are respectively in contact with the inner surface of the square frame 1;

[0040] The positioning blocks 10 are divided into four groups: front, rear, left and right. The front and rear groups of positioning blocks 10 are symmetrically distributed and contact the two cross beams 101 respectively. The left and right groups of positioning blocks 10 are symmetrically distributed and contact the two longitudinal beams 102. The lower end of the positioning block 10 is close to the cross beam 101 or the longitudinal beam 102 and is provided with an inclined surface.

[0041] Working principle: The separation state of the stretcher 5 and the frame 1 is as follows: Figure 4 As shown, at this time, the armrest 4 is in a horizontal state like the frame 1, so the armrest 4 will not affect the placement and handling of the stretcher 5 on the frame 1;

[0042] In the process of placing the stretcher 5 on the frame 1, ensure that the positioning block 10 is aligned with the inner surface of the frame 1, and setting the lower end of the positioning block 10 as an inclined surface can also help align the positioning block 10 with the inner surface of the frame 1, thereby improving the convenience of taking and placing the stretcher 5. After the stretcher 5 is placed on the frame 1, the armrest 4 is flipped upward to rotate around the axis of the connecting shaft 6 along with the connecting shaft 6 until the limit member 701 approaches the support member 702, and then the armrest 4 is pushed diagonally downward to make the armrest 4 and the limit member 701 slide toward the support member 702 until the limit member 701 rests on the upper surface of the support member 702, thereby completing the deployment of the armrest 4. At this time, pushing the armrest 4 can push the entire flat car to move through the connecting assembly 7, thereby achieving the purpose of pushing the flat car to move by pushing the armrest 4.

[0043] The utility model provides Figure 1 、 Figure 2 、 Figures 6 to 13 The second embodiment of the flat cart for cardiovascular medicine shown in the figure: the frame 1 includes two square tube-shaped cross beams 101 arranged at the front and rear and two longitudinal beams 102 arranged at the left and right. The two cross beams 101 are provided with a fixing assembly 9 connected to the positioning block 10; the fixing assembly 9 includes an elastic plate 901 and a clamping block 902, one end of the elastic plate 901 is fixedly connected to the inside of the cross beam 101, and the clamping block 902 is fixedly connected to the elastic plate 901. A through hole 1013 is provided on the upper side of the cross beam 101 close to the positioning block 10, and one end of the clamping block 902 extends out of the cross beam 101 through the through hole 1013, and the outer end of the clamping block 902 is provided with a chamfer, and the front and rear two groups of positioning blocks 10 are provided with a fixing hole 1001 adapted to the chamfered end of the clamping block 902 on the side close to the cross beam 101, and the chamfered end of the clamping block 902 is inserted into the interior of the fixing hole 1001;

[0044] A transmission assembly 8 connected to the connecting shaft 6 is provided on one side of the two crossbeams 101, and a blocking assembly 11 is provided inside the two crossbeams 101 along the length direction. The blocking assembly 11 is connected to the transmission assembly 8 and the fixing assembly 9 respectively;

[0045] The blocking assembly 11 includes a sliding rod 1101, a guide member 1102, and a stopper 1103. The guide member 1102 is fixedly connected to the inner surface of the beam 101, and a sliding cavity is formed between the guide member 1102 and the inner side wall of the beam 101. The sliding rod 1101 is slidably connected to the sliding cavity. The stopper 1103 is fixedly connected to the outer surface of the sliding rod 1101. The stopper 1103 abuts against the outer surface of the elastic plate 901 on the side close to the block 902, and the end of the stopper 1103 close to the elastic plate 901 is chamfered.

[0046] The transmission assembly 8 includes a gear 801, a rack 802 and a protective cover 803. The gear 801 is fixedly mounted on the connecting shaft 6. The rack 802 is located inside the beam 101 and fixed to the outside of the sliding rod 1101. The rack 802 is meshed with the gear 801. The protective cover 803 is fixedly connected to the outer surface of the beam 101 and is sleeved on the outside of the gear 801. The protective cover 803 is rotationally connected to the connecting shaft 6.

[0047] An installation opening 1011 is provided on the outer surface of the crossbeam 101 near the fixing assembly 9 , and a cover plate 1012 is detachably connected to the outside of the installation opening 1011 .

[0048] Working principle: When placing the stretcher 5 on the frame 1 in the flat car, several positioning blocks 10 are inserted into the inner cavity of the frame 1 (the inner cavity refers to the space surrounded by two cross beams 101 and two longitudinal beams 102). At this time, several positioning blocks 10 just contact the inner surface of the inner cavity of the frame 1, and the inclined surface at the lower end of the positioning block 10 can help the positioning block 10 to quickly align with the inner surface of the frame 1, so as to achieve the purpose of auxiliary positioning and ensure that the stretcher 5 can be placed in the correct position on the flat car. At this time, the status of the armrest 4, transmission assembly 8, blocking assembly 11 and fixing assembly 9 is as follows: Figures 11 to 13 As shown, and because the outer end of the clamping block 902 is provided with a chamfer, when the positioning block 10 is inserted into the inner cavity of the frame 1, the positioning block 10 close to the cross beam 101 will first squeeze the chamfered end of the clamping block 902 to push the clamping block 902 into the interior of the cross beam 101. During this process, the clamping block 902 will squeeze the elastic plate 901 to a certain extent, and cause the elastic plate 901 to undergo a certain degree of elastic deformation, until the fixing hole 1001 on the positioning block 10 corresponds to the position of the clamping block 902. Under the action of the rebound force of the elastic plate 901, the clamping block 902 can be reset and inserted into the fixing hole 1001 on the positioning block 10. At this time, the stretcher 5 can be preliminarily fixed to the frame 1 by the cooperation between the clamping block 902 and the fixing hole 1001.

[0049] Then, in the process of turning the armrest 4 upward, Figure 13 As shown, the armrest 4 can drive the connecting shaft 6 and the gear 801 to rotate clockwise. At this time, the gear 801 can drive the rack 802 and the sliding rod 1101 to slide in the horizontal direction away from the armrest 4. After the armrest 4 is flipped over, the sliding rod 1101 also drives the stopper 1103 to slide to the elastic plate 901, and the stopper 1103 will abut against the outer surface of the elastic plate 901 corresponding to the block 902. Figures 6 to 9 As shown, the deformation of the elastic plate 901 is restricted, thereby fixing the clamping block 902 in the fixing hole 1001, and then fixing the positioning block 10 on the frame 1, thereby fixing the stretcher 5 on the flatbed cart;

[0050] When the armrest 4 is flipped back to the horizontal state, the transmission assembly 8 will also drive the blocking assembly 11 to reset, and thereby the fixing assembly 9 will drive the stopper 1103 to separate from the elastic plate 901, until the armrest 4 is flipped back to the horizontal state. At this time, since the elastic plate 901 is no longer blocked by the stopper 1103, the stretcher 5 can be directly lifted up and separated from the frame 1, thereby releasing the stretcher 5 from being fixed.

[0051] In summary, after the stretcher 5 is placed on the frame 1, the armrest 4 is flipped upward to fix the stretcher 5 on the frame 1 through the transmission assembly 8, the blocking assembly 11 and the fixing assembly 9. At this time, the flatbed cart can be pushed by pushing the armrest 4, and it can be ensured that the stretcher 5 will not shake during the pushing process, thereby ensuring the stability of the placement of the stretcher 5. After the armrest 4 is flipped downward to a horizontal state, the blocking assembly 11 is separated from the fixing assembly 9, and the fixation of the stretcher 5 can be released at this time, so that the stretcher 5 can be taken and carried.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
