Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oxygen cylinder hanger structure applied to a folding stretcher. Background Technology

[0002] Folding stretchers are widely used in emergency rescue and field medical care due to their lightweight and portability. To meet the needs of convenient carrying and use of oxygen cylinders during emergency rescue, an oxygen cylinder hanger structure has been designed. This structure can automatically adapt when the stretcher is folded and unfolded, ensuring that the oxygen cylinder is stably fixed, making it convenient for rescuers to quickly access and improving the efficiency of emergency rescue.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing oxygen cylinder hanger structure used in folding stretchers cannot provide stable support for the oxygen cylinders and ensure the stability of the oxygen cylinder hanger in different scenarios. During use, because the hanger cannot provide stable support, the oxygen cylinders are prone to shaking, tilting, or even tipping over. This may not only damage the oxygen cylinders themselves, such as the cylinder body breaking or the valve deforming, but may also cause gas leaks. If exposed to open flames or static electricity, it can easily cause fires or explosions, posing a serious threat to surrounding personnel and property. Unstable oxygen cylinders may suddenly fall or collide with medical staff and patients during stretcher movement, causing injuries such as crushing injuries or abrasions, bringing additional injury risks to medical rescue work.

[0004] Therefore, this utility model proposes an oxygen cylinder hanger structure for use on folding stretchers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oxygen cylinder hanger structure for use on folding stretchers.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an oxygen cylinder hanger structure applied to a folding stretcher, comprising:

[0007] Support plate;

[0008] A hanging bracket assembly is placed on one side of a support plate. The hanging bracket assembly includes a support ring fixed to one side of the support plate, a fixing ring fixed on the side of the support plate away from the support ring, a buckle rotatably connected to the fixing ring, a buckle seat provided on the side of the fixing ring near the buckle, and an installation clip fixed on the side of the support plate away from the support ring.

[0009] A support assembly is placed at the bottom of a support plate. The support assembly includes a fixed plate fixed to the bottom of the support plate. An electric telescopic rod is installed at the bottom of the fixed plate. A connecting block is fixed to the output end of the electric telescopic rod. A first rotating rod is rotatably connected to the connecting block. A second rotating rod is rotatably connected to the other end of the first rotating rod. A support block is rotatably connected to one end of the second rotating rod.

[0010] Furthermore, the buckle is disposed within the buckle seat.

[0011] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to fix the oxygen cylinder, the operator rotates the buckle, and the buckle rotates along the rotation connection point between it and the fixing ring until the buckle is precisely embedded in the buckle seat. The two fit tightly together to form a stable constraint, preventing the oxygen cylinder from falling off the hanger due to shaking, and providing a key guarantee for fixing the oxygen cylinder.

[0012] Furthermore, a guide rod is fixed on the side of the fixing plate near the connecting block, and the connecting block is slidably connected to the guide rod.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: the guide rod fixed on the fixed plate near the connecting block plays a key guiding role. When the electric telescopic rod drives the connecting block to move up and down, the connecting block can only slide along the guide rod, ensuring the accuracy of the moving path of the connecting block and avoiding deviation. This ensures that the first rotating rod and the second rotating rod can move along the predetermined trajectory, achieving stable support and adjustment.

[0014] Furthermore, the other end of the second rotating rod is rotatably connected to the fixed plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: one end of the second rotating rod is rotatably connected to the support block, and the other end is rotatably connected to the fixed plate. When the electric telescopic rod drives the connecting block to move, causing the first rotating rod to rotate, the second rotating rod rotates synchronously around the rotation point on the fixed plate. By coordinating with the first rotating rod, the height and angle of the support block are adjusted to achieve flexible and stable support.

[0016] Furthermore, both the support ring and the fixing ring are equipped with limit components.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the limiting component in the support ring and the fixed ring is composed of a spring and a limiting plate.

[0018] Furthermore, the limiting component includes a spring sheet fixed within the support ring and the fixing ring.

[0019] The beneficial effect of adopting the above-mentioned further solution is that when the oxygen cylinder is placed on the support ring or fitted into the fixing ring, it will squeeze the limiting plate, causing the spring to undergo elastic deformation.

[0020] Furthermore, a limit plate is fixed to one end of the spring piece away from the support ring.

[0021] The beneficial effects of adopting the above-mentioned further solution are: the elastic force of the spring plate drives the limiting plate to press tightly against the oxygen cylinder, restricting its displacement, enhancing the fixing effect of the oxygen cylinder from multiple directions, and ensuring the stability of the oxygen cylinder on the hanger.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, when an oxygen cylinder needs to be placed, the oxygen cylinder is placed on the support ring, which provides initial support. Then, the buckle is rotated to engage with the buckle seat, thus securing the oxygen cylinder between the support ring and the buckle, thereby fixing the oxygen cylinder to the bracket assembly. The support assembly is used to adjust the height and support status. Activating the electric telescopic rod causes the connecting block to move up and down. When the connecting block moves, it causes the first and second rotating rods to rotate around their respective rotation points, thereby adjusting the height and angle of the support block. When the support block contacts the oxygen cylinder and is adjusted to a suitable position, it provides stable support for the oxygen cylinder, ensuring the stability of the oxygen cylinder bracket in different scenarios.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-5 As shown, this embodiment provides a technical solution: an oxygen cylinder hanger structure applied to a folding stretcher, comprising:

[0036] Support plate 1;

[0037] Hanger assembly 2 is placed on one side of support plate 1. Hanger assembly 2 includes a support ring 21 fixed on one side of support plate 1, a fixing ring 22 fixed on the side of support plate 1 away from support ring 21, a buckle 23 rotatably connected to fixing ring 22, a buckle seat 24 provided on the side of fixing ring 22 near buckle 23, and an installation clip 25 fixed on the side of support plate 1 away from support ring 21.

[0038] Support assembly 3 is located at the bottom of support plate 1. Support assembly 3 includes a fixing plate 31 fixed to the bottom of support plate 1. An electric telescopic rod 32 is installed at the bottom of the fixing plate 31. A connecting block 33 is fixed to the output end of the electric telescopic rod 32. A first rotating rod 35 is rotatably connected to the connecting block 33. A second rotating rod 36 is rotatably connected to the other end of the first rotating rod 35. A support block 37 is rotatably connected to one end of the second rotating rod 36. When medical personnel or rescue personnel need to place the oxygen cylinder, they first carefully place it on the support ring 21. The support ring 21 is meticulously designed in structure and dimensions to naturally conform to the bottom contour of the oxygen cylinder, providing solid initial support. At this stage, the oxygen cylinder is initially stabilized on the hanger. Next, to further ensure the cylinder's stability, the operator rotates the buckle 23. The buckle 23 is connected to the fixing ring 22 via a precise rotating connection point, allowing it to rotate freely. As it rotates, the buckle 23 gradually approaches the buckle seat 24 until it is precisely embedded in it. Once engaged, the support ring 21 and buckle 23 are firmly secured from both sides. By securing the oxygen cylinder, the risk of it detaching from the hanger due to shaking during stretcher movement is greatly reduced, successfully achieving reliable fixation of the oxygen cylinder by the hanger assembly 2. The support assembly 3 plays a crucial adjustment role in the entire hanger system. When the operator activates the electric telescopic rod 32, its output end begins to operate, driving the connecting block 33 to move up and down. Under the precise guidance of the guide rod 34, the connecting block 33 can only move in a predetermined direction, avoiding deviation. The movement of the connecting block 33 then drives the first rotating rod 35, which is rotatably connected to it. The first rotating rod 35 rotates around its rotation point, which in turn pulls the second rotating rod 36 to rotate synchronously around the rotation point on the fixed plate 31. Under this series of coordinated actions, the height and angle of the support block 37 can be flexibly adjusted. When the support block 37 contacts the oxygen cylinder and is adjusted to the appropriate position, it can provide stable support for the oxygen cylinder from the bottom. Whether transported in a flat hospital corridor or in a rugged outdoor rescue scenario, it can ensure that the oxygen cylinder hanger remains stable at all times, providing strong support for the smooth progress of rescue work.

[0039] The above solutions also have the problem that when the oxygen cylinder is fixed within the support ring 21 and the fixing ring 22, it cannot provide stable constraint for the oxygen cylinder. Figures 1-2 as well as Figure 5 As shown: The buckle 23 is set inside the buckle seat 24. When fixing the oxygen cylinder, the operator applies force to rotate the buckle 23. The rotation connection point between the buckle 23 and the fixing ring 22 gives the buckle 23 the ability to rotate flexibly. During the rotation, the buckle 23 gradually moves closer to the buckle seat 24. When the two are precisely matched, a tight constraint structure is formed. This stable connection can effectively counteract the shaking generated when the stretcher moves, greatly reducing the possibility of the oxygen cylinder falling off the hanger. It is a key link to ensure the fixation of the oxygen cylinder.

[0040] like Figure 1 as well as Figures 3-4 As shown, a guide rod 34 is fixed on the side of the fixed plate 31 near the connecting block 33. The connecting block 33 is slidably connected to the guide rod 34. When the electric telescopic rod 32 is activated, it pushes the connecting block 33 to move up and down. The guide rod 34 acts like a track, limiting the connecting block 33 to slide only along it. In this way, the movement path of the connecting block 33 is precise and controllable, avoiding abnormal support adjustment caused by offset, and ensuring that the first rotating rod 35 and the second rotating rod 36 can follow the designed trajectory. The movement achieves stable support adjustment. The other end of the second rotating rod 36 is rotatably connected to the fixed plate 31. One end of the second rotating rod 36 is rotatably connected to the support block 37, and the other end is connected to the fixed plate 31. When the electric telescopic rod 32 drives the connecting block 33 and drives the first rotating rod 35 to rotate, the second rotating rod 36 rotates synchronously around the connection point on the fixed plate 31. The two rotating rods cooperate with each other and flexibly adjust the height and angle of the support block 37 according to actual needs, providing stable support for oxygen cylinders that is suitable for different scenarios.

[0041] like Figure 1 as well as Figure 5 As shown, both the support ring 21 and the fixed ring 22 are equipped with limiting components 4. The limiting components 4 in the support ring 21 and the fixed ring 22 are composed of a spring piece 41 and a limiting plate 42. The limiting components 4 include a spring piece 41 fixed in the support ring 21 and the fixed ring 22. When the oxygen cylinder is placed in it, its own weight squeezes the limiting plate 42, causing the spring piece 41 to undergo elastic deformation. The end of the spring piece 41 away from the support ring 21 is fixed with the limiting plate 42. The elastic restoring force of the spring piece 41 will drive the limiting plate 42 to press tightly against the oxygen cylinder, constraining the oxygen cylinder from multiple directions, effectively limiting its displacement, and comprehensively enhancing the stability of the oxygen cylinder on the hanger.

[0042] like Figures 1-5As shown, the oxygen cylinder hanger structure of the folding stretcher consists of a support plate 1, a hanger assembly 2, and a support assembly 3 working together. These components work closely together to ensure stable placement and flexible adjustment of the oxygen cylinder in various scenarios. The hanger assembly 2 is located on one side of the support plate 1, with a support ring 21 and a fixing ring 22 positioned at opposite ends. When placing the oxygen cylinder, it is first placed on the support ring 21, which is designed to fit snugly against the bottom of the cylinder, providing initial stable support. Then, the operator rotates the buckle 23, which rotates flexibly around the point of rotation with the fixing ring 22 until it is engaged with the buckle seat 24. The support ring 21 and buckle 23 clamp the oxygen cylinder from both sides, greatly reducing the risk of it shaking and falling off. Simultaneously, the limiting components 4 within the support ring 21 and fixing ring 22 function to limit the compression of the oxygen cylinder. Plate 42 deforms the spring 41, and its elastic restoring force drives the limiting plate 42 to constrain the oxygen cylinder from multiple directions, enhancing stability. The support component 3 is located at the bottom of the support plate 1. After the electric telescopic rod 32 is activated, its output end drives the connecting block 33. The connecting block 33 is restricted by the guide rod 34 and can only slide precisely along it to avoid deviation. The movement of the connecting block 33 drives the first rotating rod 35 to rotate around the rotation point, which in turn pulls the second rotating rod 36 to rotate synchronously around the rotation point on the fixed plate 31. Through the cooperation of the two rotating rods, the height and angle of the support block 37 can be flexibly adjusted. Whether on the flat ground of the hospital or in the rugged outdoor environment, the support block 37 can provide suitable and stable support for the oxygen cylinder from the bottom, ensuring the stability of the oxygen cylinder hanger and laying the foundation for the smooth progress of rescue work.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
