Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an oxygen cylinder cart. Background Art

[0002] Oxygen cylinders are standing equipment in hospitals. They store oxygen and are used to supply oxygen to patients to ensure that their vital signs are normal. Oxygen cylinders are pressure vessels. According to national standards, their overall structure is a tall and thin cylinder. The bottom of the oxygen cylinder is connected to the cylindrical arc. When in use, the oxygen cylinder is required to be placed stably. At the same time, during use in the hospital, based on the needs of rescue and replacement after the oxygen is used up, the oxygen cylinder is required to be easy to move. For the above reasons, the oxygen cylinder needs to be placed on a cart to achieve the purpose of stable placement and easy movement.

[0003] The oxygen cylinder carts currently used are Figure 1 As shown, it includes a chassis 1 and a pull rod 2, a limiting ring 3 is fixedly provided on the top surface of the chassis 1, rollers 4 are rotatably provided on both sides of one end of the chassis 1, and a cushion block 5 is provided on the bottom surface of the other end of the chassis 1. Under the support of the cushion block 5 and the roller 4, the chassis 1 can be placed horizontally; the pull rod 2 is an integrally formed U-shaped rod structure, which includes a cross bar and two straight bars, the bottom end of the straight bar is fixedly connected to the top surface of one end of the chassis 1 close to the roller 4, and the two ends of the cross bar are respectively connected to the top of the two straight bars (in the actual product, the arc connection between the end of the cross bar and the straight bar makes the cross bar bend away from the limiting ring 3). When the oxygen cylinder cart is in use, the bottom of the oxygen cylinder is placed in the limiting ring 3 and limited by the limiting ring 3; in addition, a strap or an iron chain is connected to the straight bar of the pull rod 2, so that it bypasses the oxygen cylinder body and the straight bar of the pull rod 2 to limit the upper part of the oxygen cylinder. Thus, the oxygen cylinder is placed on the cart, and the cart is placed vertically when the oxygen cylinder is in use, and the oxygen cylinder is kept vertically and stably supported by the cushion block 5 and the roller 4; when the oxygen cylinder needs to be moved, the cross bar of the pull rod 2 is held, and the cart is tilted with the roller 4 as a fulcrum to be dragged as a whole.

[0004] The above oxygen cylinder cart has a simple structure and can achieve the purpose of stably placing the oxygen cylinder and facilitating movement. However, in practical applications, it still has at least the following defects:

[0005] First, on the oxygen cylinder cart, the bottom of the oxygen cylinder is limited by a limit ring 3, and the height of the limit ring 3 is limited (if the limit ring 3 is too high, it will be difficult to load the oxygen cylinder on the cart), and it cannot achieve a good limiting effect; the upper and middle parts of the oxygen cylinder are limited by straps or chains, and the straps or chains currently used are only loosely wrapped around the outside of the oxygen cylinder, which only play an auxiliary limiting role. When the oxygen cylinder cart is dragged quickly or when getting on and off an ambulance, the bottom of the oxygen cylinder is prone to axially slipping out of the limit ring 3.

[0006] Secondly, since the cushion block 5 and the limiting ring 3 have a certain height, when replacing and loading the oxygen cylinder, the oxygen cylinder needs to be lifted as a whole and the bottom of the oxygen cylinder needs to be accurately inserted into the limiting ring 3. Since the overall weight of the oxygen cylinder is heavy, the loading process of the oxygen cylinder is extremely inconvenient. Utility Model Content

[0007] The utility model aims to overcome the deficiencies of the prior art and to provide an oxygen cylinder trolley, on which the oxygen cylinders can be tied and tightly held when loading them, and the operation process is labor-saving and convenient.

[0008] The purpose of this utility model is achieved through the following technical solutions:

[0009] The trolley is a kind of oxygen cylinder trolley, comprising a bottom plate, a U-shaped rod and a plurality of binding mechanisms, wherein rollers are rotatably arranged on both sides of one end of the bottom plate, the U-shaped rod comprises a cross rod and two straight rods, the bottom end of the straight rod is fixedly connected to the top surface of one end of the bottom plate close to the roller, the two ends of the cross rod are respectively connected to the other ends of the two straight rods, and the distance between the two straight rods is adapted to the size of the oxygen cylinder body; the binding mechanism comprises a buckle and a binding strap, the buckle comprises a buckle body, a sliding tongue and a spring, the buckle body is provided with a through hole and a sliding hole perpendicular to each other, the sliding tongue can be slidably arranged in the sliding hole, the two ends of the spring are respectively connected to the sliding tongue and the buckle body, one end of the sliding tongue is processed into a wedge surface and can extend into the through hole, one end of the binding strap is connected to one of the straight rods, the buckle body is connected to the other straight rod, the other end of the binding strap is provided with a ratchet and is penetrated in the through hole, and the sliding tongue is adapted to the ratchet. The oxygen cylinder trolley can load oxygen cylinders labor-savingly and conveniently, and after the oxygen cylinders are loaded, they are clamped tightly on two straight rods with straps. The overall structure is stable and can cope with the needs of use in scenarios such as quickly dragging the oxygen cylinder trolley and getting on and off an ambulance.

[0010] Furthermore, the binding mechanism includes two buckles, and the two buckles are respectively connected to two straight rods. Ratchets are provided at both ends of the strap. The two ends of the strap are respectively inserted into the through holes of the two buckle bodies, and the strap can be removed when the oxygen cylinder is replaced.

[0011] Furthermore, the buckle also includes a sliding sleeve, which is slidably mounted on the straight rod, and the buckle body is fixedly connected to the side wall of the sliding sleeve. When loading the oxygen cylinder, the sliding sleeve can be slid to move the binding mechanism to a preferred binding and clamping position.

[0012] Furthermore, a mounting sleeve is fixedly provided on the top surface of the bottom plate, the bottom end of the straight rod is fixedly inserted into the mounting sleeve, and the diameter of the mounting sleeve is the same as the diameter of the sliding sleeve.

[0013] Furthermore, an unlocking piece is connected to one end of the sliding tongue away from the through hole, and the other end of the unlocking piece extends out of the buckle body. The unlocking piece can be held and the sliding tongue can be pulled outward to unlock the buckle, making it convenient to remove the strap.

[0014] Furthermore, the unlocking member is a screw rod, the end of which is threadedly connected to the sliding tongue, and unscrewing and removing the screw rod can avoid the loosening of the strap due to accidental unlocking.

[0015] Furthermore, a through hole is processed at one end of the binding strap near the ratchet, and a rod-shaped object passing through the through hole can facilitate force application when tightening the binding strap.

[0016] The beneficial effects of the utility model are:

[0017] The oxygen cylinder cart includes a base plate, a U-shaped rod and a plurality of binding mechanisms. One end of the base plate is provided with rollers that can rotate on both sides. The U-shaped rod includes a cross bar and two straight rods. The bottom end of the straight rod is fixedly connected to the top surface of the base plate. The two ends of the cross bar are respectively connected to the top ends of the two straight rods. The oxygen cylinder cart can be conveniently dragged by holding the cross bar. The distance between the two straight rods is adapted to the size of the oxygen cylinder body. The binding mechanism includes a buckle and a strap. A sliding tongue is provided in the buckle. The strap is processed with ratchets near the end. The strap can pass through the buckle in one direction and be locked by the sliding tongue in the other direction. When loading the oxygen cylinder, the oxygen cylinder can be dragged onto the base plate by rotating and dragging without lifting the oxygen cylinder, which is more labor-saving. After placing the oxygen cylinder on the base plate, the strap is passed around the oxygen cylinder body and the end of the strap is passed through the buckle. Then the strap is tightened. The binding mechanism can hold and fix the oxygen cylinder through the strap and the two straight rods. It can be seen that the use of the oxygen cylinder trolley can save effort and conveniently complete the oxygen cylinder loading work, and after loading is completed, the oxygen cylinder is tied and held tightly on the trolley and will not fall out, which can meet the needs of special scenarios such as quickly dragging the oxygen cylinder trolley and getting on and off an ambulance.

DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0025] like Figures 2 to 5 As shown, an oxygen cylinder cart comprises a bottom plate 6, a U-shaped rod 7 and a plurality of tying mechanisms.

[0026] Rollers 4 are rotatably arranged on both sides of one end of the bottom plate 6. The U-shaped rod 7 includes a crossbar and two straight rods, the bottom end of the straight rod is fixedly connected to the top surface of one end of the bottom plate 6 close to the roller 4, and the two ends of the crossbar are respectively connected to the other ends of the two straight rods (refer to the existing cart pull rod design to be connected in an arc); different from the existing cart pull rod, the distance between the two straight rods in the U-shaped rod 7 is smaller than the diameter of the oxygen cylinder body, and one side of the outer wall of the oxygen cylinder can be limited by the two straight rods.

[0027] The binding mechanism includes a buckle and a binding belt 8. The binding belt 8 is made of a steel belt, a plastic belt, etc. with certain flexibility and strength. Figure 3 , Figure 4 As shown, it includes a buckle body 9, a sliding tongue 10 and a spring 11. The buckle body 9 is provided with a rectangular through hole 12 and a sliding hole 13 which are perpendicular to each other. The sliding tongue 10 is slidably arranged in the sliding hole 13. The two ends of the spring 11 are respectively connected to the sliding tongue 10 and the buckle body 9. The spring 11 is used to provide elastic force for the sliding tongue 10 to slide in the direction of the through hole 12, so that one end of the sliding tongue 10 extends into the through hole 12. A wedge surface is processed at the end of the sliding tongue 10 extending into the through hole 12. Figure 2 , Figure 5 As shown, one end of the strap 8 is connected to a straight rod, the buckle body 9 is connected to another straight rod, and the other end of the strap 8 is provided with a ratchet 14 and is inserted into the through hole 12. The sliding tongue 10 and the ratchet 14 are adapted so that the strap 8 can only pass through the through hole 12 in one direction. Specifically, the ratchet 14 contacts the wedge surface of the sliding tongue 10 during the process of the strap 8 passing through the through hole 12, which can push the sliding tongue 10 to slide backward in the sliding hole 13 and compress the spring 11. When the ratchet 14 passes the position of the sliding tongue 10, the sliding tongue 10 slides forward under the action of the spring 11, and the ratchet 14 can be clamped and cannot be withdrawn.

[0028] When the oxygen cylinder cart is loaded with oxygen cylinders, the following steps can be followed after the connection between the strap 8 and the buckle is untied:

[0029] S1. Rotate and drag the oxygen cylinder onto the bottom plate 6 so that it is close to the two straight rods of the U-shaped rod 7. Since the bottom plate 6 is a flat plate, the oxygen cylinder can be directly moved onto the bottom plate 6 by rotating and dragging, without lifting the oxygen cylinder as a whole, which is more labor-saving.

[0030] S2, hold the crossbar of the U-shaped rod 7, and tilt the entire cart with the roller 4 as the fulcrum, and the oxygen cylinder slides under its own weight to the two straight rods supported on the U-shaped rod 7. Since the roller 4 is used as the fulcrum, the tilting process is not laborious based on the lever principle.

[0031] S3, wrap the strap 8 around the oxygen cylinder body, and let the end of the strap 8 pass through the through hole 12 of the buckle body 9. Since the strap 8 can only pass through the through hole 12 in one direction, the strap 8 can be tightened outwards to hold the oxygen cylinder tightly through the strap 8 and the two straight rods of the U-shaped rod 7, so that the loading is stable. In specific implementation, a through hole 15 is processed at one end of the strap 8 near the ratchet 14. During operation, a rod such as a pen holder can be passed through the through hole 15 to facilitate the use of force when tightening the strap 8, which is extremely convenient to operate.

[0032] It can be seen from the above process that the oxygen cylinder cart no longer needs to lift the oxygen cylinder when loading the oxygen cylinder, and the operation process is more labor-saving and convenient; the oxygen cylinder can be tightly clamped by the two straight rods of the strap 8 and the U-shaped rod 7, and multiple binding mechanisms are provided, which can respectively clamp the oxygen cylinder body in multiple areas in the height direction, so that the oxygen cylinder can be stably loaded on the oxygen cylinder cart without falling out, which can meet the use needs of special scenarios such as quickly dragging the oxygen cylinder cart and getting on and off the ambulance.

[0033] Furthermore, the binding mechanism includes two buckles, which are respectively connected to the two straight rods of the U-shaped rod 7. Ratchets 14 are provided at both ends of the binding strap 8, and the two ends of the binding strap 8 are respectively inserted into the through holes 12 of the two buckle bodies 9. Both ends of the binding strap 8 are connected to the straight rods through the buckles, and the binding strap 8 can be removed as a whole during loading to avoid interference in the above S1 process.

[0034] Furthermore, the buckle further includes a sliding sleeve 16, which is slidably mounted on the straight rod of the U-shaped rod 7, and the buckle body 9 is fixedly connected to the side wall of the sliding sleeve 16. In the aforementioned step S2, the sliding sleeve 16 can be slid to adjust the position of the strap 8 to the preferred binding position, further ensuring that the oxygen cylinder is firmly bound.

[0035] Furthermore, a mounting sleeve 17 is fixedly provided on the top surface of the bottom plate 6, and the straight rod bottom end of the U-shaped rod 7 is fixedly inserted into the mounting sleeve 17, and the diameter of the mounting sleeve 17 is the same as the diameter of the sliding sleeve 16. Since after the sliding sleeve 16 is added, the outer wall of one side of the oxygen cylinder is tightly pressed against the sliding sleeve 16 after being tightly held, setting the diameter of the mounting sleeve 17 to be the same as the diameter of the sliding sleeve 16 is conducive to pressing the bottom end of the oxygen cylinder tightly when the oxygen cylinder is tightly held.

[0036] Furthermore, an unlocking piece 18 is connected to one end of the sliding tongue 10 away from the through hole 12, and the other end of the unlocking piece 18 extends out of the buckle body 9. The sliding tongue 10 can be pulled outward by holding the unlocking piece 18, so as to facilitate the removal of the strap 8 when replacing the oxygen cylinder.

[0037] Furthermore, the unlocking member 18 is directly a screw, the end of which is threadedly connected to the sliding tongue 10. After the oxygen cylinder 8 is loaded and tied and clamped, the unlocking member 18 can be screwed out and removed to avoid accidental unlocking and causing the strap 8 to loosen.

[0038] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
