Description

Technical Field

[0001] The utility model relates to the technical field of oxygen cylinder fixing, in particular to an oxygen cylinder rack for a wheelchair. Background Art

[0002] In clinical practice, older patients with leg diseases often need to be transferred with the aid of wheelchairs; some patients also need to carry oxygen cylinders for oxygen inhalation, but most traditional wheelchairs do not have devices for carrying oxygen cylinders, and they are often carried by medical staff or placed on the patient's legs, which is inconvenient to use; in recent years, brackets installed on wheelchairs for carrying oxygen cylinders have also appeared on the market, but the brackets will limit the folding of the wheelchair, and the wheelchair cannot be folded and stored when not in use.

[0003] For example, Chinese patent publication number CN217660484U discloses a wheelchair with an oxygen cylinder hanger structure, which also has the function of carrying oxygen cylinders.

[0004] However, the applicant found that the wheelchair in the above-mentioned reference document carries an oxygen cylinder by placing the oxygen cylinder in the oxygen cylinder mounting seat and the circular steel ring. Since the sizes of oxygen cylinders used in different hospitals and families vary, if the oxygen cylinder carried is shorter, when the oxygen cylinder is placed in the oxygen cylinder mounting seat and the circular steel ring, the bottle mouth operation part on the oxygen cylinder (used to open or close the valve of the oxygen cylinder) will be far away from the top circular steel ring, requiring the user to put his arm into the circular steel ring for operation, which is inconvenient to open or close the valve and install the air pipe on the valve.

[0005] If the oxygen cylinder carried is long, the placed oxygen cylinder may exceed the backrest of the wheelchair, which brings inconvenience to pushing the wheelchair from the back. In summary, the oxygen cylinder mounting seat on the wheelchair in the above-mentioned comparative document cannot adjust the placement position of the oxygen cylinder according to the actual size of the oxygen cylinder when carrying oxygen cylinders of different specifications, which brings inconvenience to opening and closing the oxygen cylinder valve or installing the air pipe. Utility Model Content

[0006] In view of this, the purpose of the utility model is to propose an oxygen cylinder rack for a wheelchair to solve the problem that the oxygen cylinder rack on the existing wheelchair is usually set at the rear of the wheelchair, and when fixing oxygen cylinders of different specifications, the placement height of the oxygen cylinder cannot be adjusted, resulting in the bottle mouth operation of some shorter oxygen cylinders being located inside the oxygen cylinder rack, and the need to reach into the bottle rack for operation.

[0007] Based on the above purpose, the utility model provides an oxygen cylinder rack for a wheelchair, which is used to enable the wheelchair body to carry an oxygen cylinder, comprising an arc-shaped plate, a sleeve is fixedly connected to the bottom of the arc-shaped plate, the sleeve can be sleeved on the crossbeam of the wheelchair body, a buckle is fixedly connected to the side of the arc-shaped plate, and the buckle is fixedly installed on the vertical beam of the wheelchair body through bolts and nuts, both sides of the arc-shaped plate close to the top are fixedly connected with fixed arc-shaped placement plates, two movable arc-shaped placement plates are slidably arranged on the arc-shaped plate, and the inner sides of the two movable arc-shaped placement plates are fixedly connected with placement plates for placing oxygen cylinders;

[0008] The arc plate is provided with a through groove, and a moving part for pushing the movable arc placing plate to move is arranged in the through groove. Both the fixed arc placing plate and the movable arc placing plate are provided with a fixing part. When the oxygen cylinder is placed on the placing plate, the placing plate can be pushed to move under the action of the moving part, so that the bottle mouth operating point of the oxygen cylinder can be close to the top of the arc plate. At the same time, the fixing parts on the fixed arc placing plate and the movable arc placing plate can fix the oxygen cylinder.

[0009] Preferably, the moving part includes a screw rotatably connected in the through groove, a threaded sleeve is threadedly connected to the screw, the movable arc placement plate is fixedly connected to the threaded sleeve, and a movable groove for the movable arc placement plate to move is opened on the side of the arc plate.

[0010] Preferably, the inner sides of the fixed arc-shaped placement plate and the movable arc-shaped placement plate are fixedly connected with rubber pads for protecting the oxygen cylinders, and the placement plate is fixedly connected to the rubber pads.

[0011] Preferably, the fixing portion comprises a strap, and the strap is detachably mounted on the fixed arc placement plate and the movable arc placement plate, and the fixed arc placement plate and the movable arc placement plate are both fixedly connected with a buckle for the strap to pass through.

[0012] Preferably, a male Velcro is fixedly bonded to one side of the strap close to the arc plate, and female Velcro bonded to the male Velcro is fixedly bonded to the outer sides of the fixed arc placement plate and the movable arc placement plate.

[0013] Preferably, a mounting block is fixedly bonded to one end of the strap away from the buckle, and the mounting block is detachably mounted on the fixed arc placement plate and the movable arc placement plate via a locking bolt.

[0014] The beneficial effects of the utility model: the utility model provides an oxygen cylinder rack for a wheelchair, which can change the position of the movable arc-shaped placement plate and the placement plate (that is, the placement position of the oxygen cylinder can be changed) through the setting of the moving part, and with the cooperation of the fixing part, oxygen cylinders of different specifications can be fixed, so that when the wheelchair body carries oxygen cylinders of different specifications, the fixing position of the oxygen cylinder can be changed, and the oxygen cylinder can be appropriately adjusted so that the bottle mouth operation part on the oxygen cylinder can always be exposed to the outside of the oxygen cylinder rack, which is convenient for the user to operate the oxygen cylinder (open or close the valve on the oxygen cylinder) or install the air pipe, which brings convenience to the user's operation and avoids the situation that when the wheelchair body carries oxygen cylinders of different specifications, the bottle mouth operation part is located inside the oxygen cylinder rack, and the user needs to reach into the bottle rack for operation.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an oxygen cylinder rack for a wheelchair is used to enable a wheelchair body 1 to carry an oxygen cylinder, comprising an arc-shaped plate 2, a sleeve 10 is fixedly connected to the bottom of the arc-shaped plate 2, the sleeve 10 can be sleeved on the crossbeam of the wheelchair body 1, a buckle 3 is fixedly connected to the side of the arc-shaped plate 2, the buckle 3 is fixedly installed on the vertical beam of the wheelchair body 1 by bolts and nuts, both sides of the arc-shaped plate 2 near the top are fixedly connected with fixed arc-shaped placement plates 4, two movable arc-shaped placement plates 5 are slidably provided on the arc-shaped plate 2, and the inner sides of the two movable arc-shaped placement plates 5 are fixedly connected with placement trays 6 for placing oxygen cylinders;

[0024] A through groove is opened on the inner side of the arc plate 2, and a moving part 7 is arranged in the through groove. The moving part 7 can push the arc placing plate 5 and the placing tray 6 to move. Both the fixed arc placing plate 4 and the movable arc placing plate 5 are provided with a fixing part 8. When the oxygen cylinder is placed on the placing tray 6, the placing tray 6 can be pushed to move under the action of the moving part 7, so that the bottle mouth operation point of the oxygen cylinder can always be located near the top of the arc plate 2. At the same time, the fixing parts 8 on the fixed arc placing plate 4 and the movable arc placing plate 5 can fix the oxygen cylinder.

[0025] If the operating part of the bottle mouth of the oxygen cylinder is much higher than the backrest on the wheelchair body 1, it will affect the user's ability to push the wheelchair from the rear; if the operating part of the bottle mouth of the oxygen cylinder is far from the top of the curved plate 2, it is necessary to extend the arm downward into the fixed curved placement plate 4 for operation. Therefore, no matter whether the operating part of the bottle mouth of the oxygen cylinder is much higher or lower than the top of the oxygen cylinder rack, it will cause inconvenience to the operation. The present application can fix oxygen cylinders of different specifications through the arrangement of the moving part 7 and the fixing part 8, and when fixing oxygen cylinders of different specifications, the placement position of the oxygen cylinder can be adjusted so that the bottle mouth operating part on the oxygen cylinder can always be located near the top of the curved plate 2, which is convenient for operating the bottle mouth of the oxygen cylinder.

[0027] When it is necessary to carry an oxygen cylinder, first adjust the position of the placement plate 6 and the movable arc-shaped placement plate 5 appropriately according to the specifications of the oxygen cylinder, that is, by rotating the screw 71. Since the screw 71 is threadedly connected to the threaded sleeve 72, and the movement trajectory of the threaded sleeve 72 and the movable arc-shaped placement plate 5 is limited by the through groove and the movable groove, during the rotation of the screw 71, the threaded sleeve 72 can drive the placement plate 6 and the movable arc-shaped placement plate 5 to move, so that when placing the oxygen cylinder, the bottle mouth operation point on the oxygen cylinder can always be located near the top of the arc plate 2, and then the oxygen cylinder is limited and fixed by the fixing parts 8 on the fixed arc-shaped placement plate 4 and the movable arc-shaped placement plate 5.

[0028] In another preferred embodiment of the utility model, the inner sides of the fixed arc-shaped placement plate 4 and the movable arc-shaped placement plate 5 are fixedly connected with rubber pads 9 for protecting the oxygen cylinder, and the placement plate 6 is fixedly connected to the rubber pads 9. Through the setting of the rubber pads 9, the oxygen cylinder is protected when it is placed.

[0029] In another preferred embodiment of the present invention, the fixing portion 8 includes a strap 81, which is detachably mounted on one of the fixed arc placing plate 4 and the movable arc placing plate 5, and a buckle 82 for the strap 81 to pass through is fixedly connected to the other fixed arc placing plate 4 and the movable arc placing plate 5.

[0030] It should be noted that a male Velcro is fixedly bonded to one side of the strap 81 close to the arc plate 2, and a female Velcro 83 bonded to the outer side of the fixed arc placement plate 4 and the movable arc placement plate 5 is fixedly bonded, and the female Velcro 83 and the buckle 82 are located on the same side.

[0031] When it is necessary to fix the oxygen cylinders located on the fixed arc placement plate 4 and the movable arc placement plate 5, first pass the strap 81 through the buckle 82 and tighten it, and then adhere the male Velcro on the inside of the strap 81 to the female Velcro 83, so that oxygen cylinders of different specifications can be fixed.

[0032] It should be noted that a mounting block 84 is fixedly bonded to one end of the strap 81 away from the buckle 82, and the mounting block 84 is detachably mounted on the fixed arc plate 4 and the movable arc plate 5 by means of a locking bolt 85. Threaded holes are provided on the mounting block 84, the fixed arc placement plate 4 and the movable arc placement plate 5, which facilitates the mounting block 84 and the strap 81 to be mounted on the fixed arc placement plate 4 and the movable arc placement plate 5 by means of the locking bolt 85, thereby facilitating the later replacement of the strap 81.
