Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fixing device. Background Art

[0002] The fixing device of medical equipment refers to the supporting structure used to ensure that the medical equipment is firmly and reliably fixed in the designated position during use, and to prevent the equipment from being displaced or damaged due to vibration, external force or misoperation. In the fixing device of medical oxygen supply tank, it is usually designed to firmly fix the oxygen supply tank to the bed frame, wall or ground to prevent the oxygen supply tank from accidentally tipping over or sliding during movement or use, thereby ensuring the stability and safety of oxygen supply.

[0003] For example, a Chinese utility model patent (CN221592567U) discloses a fixing device for a medical oxygen supply tank, which states: "By vertically sliding the telescopic rod along the inner wall of the fixing tube, the extension length of the telescopic rod is adjusted, and then by turning the bolt, one end of the bolt is movably inserted into the interior of the corresponding positioning hole, thereby fixing the position of the telescopic rod. This can be used for oxygen supply tubes of different heights, further improving the scope of use of the equipment." It also records the technical problem that "the height fixing device for existing oxygen supply tanks cannot be used for oxygen supply tanks of different specifications, thereby reducing the scope of use of the equipment and having a poor fixing effect."

[0004] To sum up the above, it can be seen that the existing technology uses the handle on the threaded rod to adjust the position of the clamp by repeatedly rotating the handle to make it tightly attached to the oxygen supply tank, thereby achieving the purpose of clamping the oxygen supply tank. However, this method has the following technical problems: However, when the device is actually used, the oxygen supply tank needs to be moved to the bottom plate first, and the oxygen tank is generally heavy. In the process of lifting and moving the oxygen tank, the operator consumes more physical strength, which reduces the practicality of the device. For this reason, this application proposes a fixing device to solve the technical problems mentioned in the above patents and provide a new technical solution. Utility Model Content

[0005] Based on this, it is necessary to provide a fixing device to address the above technical problems. By unfolding the rotating plate, the rotating plate is in contact with the ground. At this time, the triangular block is in contact with the side of the receiving plate. Then the oxygen tank can be pushed onto the rotating plate, and a plurality of balls on the rotating plate assist in lowering the oxygen tank to the top of the receiving plate. In this process, there is almost no need to lift the oxygen tank. Only a relatively small force is needed to push the oxygen tank along the rotating plate to the receiving plate. This process is relatively labor-saving, reduces the physical exertion of the operator in the process of transferring the oxygen tank to the receiving plate, improves the practicality of the device, and After the connecting plate is connected and fixed, the rotating plate can be rotated to a vertical state relative to the receiving plate. During this process, after the insertion rod contacts the housing, as the rotating plate continues to rotate, the insertion rod can be squeezed into the inside of the support block with the assistance of the inclined surface on the insertion rod. After the rotating plate is rotated to a vertical state, the insertion rod is aligned with the hole on the first sliding ring, and then the insertion rod can be inserted into the housing under the action of the elastic force of the first spring, thereby limiting the vertical state of the rotating plate, reducing the footprint of the device when the rotating plate is not in use, and at the same time, the erected rotating plate can also provide a certain shielding and protection for the oxygen tank, thereby improving the practicability of the device.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0013] As a preferred embodiment of the fixing device provided by the present invention, the fixing mechanism includes a fixing block, a sliding assembly, and a blocking assembly. A fixing block is fixedly connected between the two adjacent front and rear shells and between the two adjacent front and rear sliding columns.

[0014] As a preferred embodiment of the fixing device provided by the present invention, the sliding assembly includes a connecting column and a clamping block, the inner wall of the fixing block is slidably connected to two connecting columns, and one end of the two connecting columns close to the middle of the receiving plate is fixedly connected to the outer wall of the clamping block.

[0015] As a preferred embodiment of the fixing device provided by the present invention, the blocking assembly includes a limiting rack, the inner wall of the fixed block is slidably connected to the limiting rack, the limiting rack is fixedly connected to the outer wall of the clamping block, the inner wall of the fixed block is slidably connected to a baffle, the outer wall of the baffle is fixedly connected to a second sliding ring, the second sliding ring is slidably connected to the inner wall of the fixed block, the outside of the fixed block is provided with a second spring, and the two ends of the second spring are respectively fixedly connected to the outer wall of the second sliding ring and the inner wall of the fixed block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The fixing device provided by the utility model unfolds the rotating plate so that the rotating plate contacts the ground, at which time the triangular block abuts against the side of the receiving plate, and then the oxygen tank can be pushed onto the rotating plate, and the multiple balls on the rotating plate assist in lowering the oxygen tank to the top of the receiving plate. In this process, there is almost no need to lift the oxygen tank, and only a relatively small force is needed to push the oxygen tank along the rotating plate to the receiving plate. This process is relatively labor-saving, reduces the physical exertion of the operator in the process of transferring the oxygen tank to the receiving plate, improves the practicality of the device, and is convenient for the operator to move the oxygen tank to the receiving plate and fix it. After being fixed, the rotating plate can be rotated to a vertical state relative to the receiving plate.

[0018] The fixing device provided by the utility model can make the limiting screw leave the corresponding sliding column by rotating the adjacent front and rear limiting screws, thereby adjusting the position of the sliding column in the housing, and further adjusting the height of the corresponding two fixing mechanisms accordingly. Then, oxygen tanks of different specifications can be clamped at corresponding appropriate heights. When clamping the oxygen tank, the connecting column or the limiting rack is pushed toward the position where the oxygen tank is located. During this process, the inclined surface of the teeth on the limiting rack will squeeze the inclined surface of the baffle, thereby causing the baffle to move upward accordingly, thereby allowing the limiting rack to slide inside the fixed block, so that the clamping block is tightly attached to the outside of the oxygen tank to complete the clamping of the oxygen tank. This process is relatively simple and convenient, and improves the practicability of the device. Due to the restriction between the vertical surface of the baffle and the vertical surface of the teeth on the limiting rack, the limiting rack cannot move directly in the direction away from the oxygen tank, so as to ensure the stability of the clamping and fixing of the oxygen tank.

[0028] In order to help those skilled in the art better understand the present invention, 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 should fall within the scope of protection of the present invention.

[0029] As described in the background technology, when the device is actually used, the oxygen supply tank needs to be moved to the bottom plate first. However, the oxygen tank is generally heavy, and the operator's physical strength is consumed in the process of lifting and moving the oxygen tank, which reduces the practicality of the device.

[0030] In order to solve this technical problem, the utility model provides a fixing device, which is used for fixing an oxygen tank.

[0031] Specifically, please refer to Figure 1-Figure 2 , the fixing device specifically includes:

[0032] A docking plate 1, with brake wheels 2 fixedly mounted on the bottom and near the four corners of the docking plate 1, and sleeves 3 fixedly connected to the top and near the four corners of the docking plate 1. The inner walls of the four sleeves 3 are slidably connected to sliding columns 4. The internal threads of the sleeves 3 are connected to limiting screws 5, which are movably inserted into the sliding columns 4. A fixing mechanism 7 is provided between the two adjacent sleeves 3 and the two adjacent sliding columns 4. Auxiliary mechanisms 6 are provided on the front and rear sides of the docking plate 1;

[0033] The auxiliary mechanism 6 includes a rotating plate 8, a support block 11, an auxiliary component, and a plug-in component. The inner wall of the receiving plate 1 is rotatably connected to the rotating plate 8, and the left and right sides of the rotating plate 8 are fixedly connected to the support blocks 11.

[0034] The fixing device provided by the present invention unfolds the rotating plate 8 so that the rotating plate 8 contacts the ground. At this time, the triangular block 9 abuts against the side of the receiving plate 1. Then the oxygen tank can be pushed onto the rotating plate 8, and the multiple balls 10 on the rotating plate 8 assist in lowering the oxygen tank to the top of the receiving plate 1. In this process, there is almost no need to lift the oxygen tank. It only needs to use a relatively small force to push the oxygen tank along the rotating plate 8 to the receiving plate 1. This process is relatively labor-saving, reduces the operator's physical exertion in the process of transferring the oxygen tank to the receiving plate 1, improves the practicality of the device, and after the oxygen tank is moved to the receiving plate 1 and fixed, it can be The rotating plate 8 is rotated to a vertical state relative to the receiving plate 1. During this process, after the insertion rod 12 contacts the housing 3, as the rotating plate 8 continues to rotate, the insertion rod 12 can be squeezed into the inside of the support block 11 with the help of the inclined surface on the insertion rod 12. After the rotating plate 8 is rotated to a vertical state, the insertion rod 12 is aligned with the hole on the first sliding ring 13, and then the insertion rod 12 can be inserted into the housing 3 under the action of the elastic force of the first spring 14, thereby limiting the vertical state of the rotating plate 8, reducing the footprint of the device when the rotating plate 8 is not in use, and at the same time, the erected rotating plate 8 can also provide a certain shielding and protection for the oxygen tank, thereby improving the practicality of the device.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figure 2-Figure 4 , a fixing device comprising:

[0038] The auxiliary component includes a triangular block 9, and a plurality of triangular blocks 9 are fixedly connected to the outer wall of the rotating plate 8. A plurality of balls 10 are rollingly connected to the side of the rotating plate 8 away from the triangular block 9. When the triangular block 9 in the auxiliary component contacts the ground on one side of the rotating plate 8, the triangular block 9 contacts the outer wall of the receiving plate 1, thereby providing support for the rotating plate 8 and improving the stability of the rotating plate 8. The oxygen tank is pushed on the rotating plate 8 by the balls 10, which is more labor-saving than the oxygen tank being directly located on the rotating plate 8.

[0039] The plug-in assembly includes an insertion rod 12, and the inner wall of the support block 11 is slidably connected with the insertion rod 12. The insertion rod 12 is movably inserted in the shell 3. The shell 3 is provided with a hole that is compatible with the insertion rod 12. The outside of the insertion rod 12 is provided with an inclined surface. The outer wall of the insertion rod 12 is fixedly connected with a first sliding ring 13, and the first sliding ring 13 is slidably connected to the inner wall of the support block 11. The outside of the insertion rod 12 is sleeved with a first spring 14, and the two ends of the first spring 14 are respectively fixedly connected to the outer wall of the first sliding ring 13 and the inner wall of the support block 11. The plug-in assembly can limit the rotating plate 8 that is folded into a vertical state, so that the rotating plate 8 can maintain a vertical state, reduce the situation where the rotating plate 8 is accidentally unfolded during the movement of the device, and improve the stability of the device.

[0040] With the above structural design, the device can be moved to the working position by the brake wheel 2, and then the brake wheel 2 is adjusted to the brake state, and then the rods 12 on the left and right sides are pulled away from each other, thereby making the rods 12 leave the corresponding housing 3, and then the rods 12 are pulled to drive the rotating plate 8 to rotate relative to the receiving plate 1, and then the rotating plate 8 is brought into contact with the ground to release the rods 12. At this time, the triangular block 9 is in contact with the side of the receiving plate 1, and then the oxygen tank can be pushed onto the rotating plate 8, and the multiple balls 10 on the rotating plate 8 assist in lowering the oxygen tank to the top of the receiving plate 1. When the oxygen tube moves to the receiving plate 1 and After it is fixed, the rotating plate 8 can be rotated to a vertical state relative to the receiving plate 1. During this process, after the insertion rod 12 contacts the housing 3, as the rotating plate 8 continues to rotate, with the assistance of the inclined surface on the insertion rod 12, the insertion rod 12 can be squeezed into the inside of the support block 11, so that the first sliding ring 13 slides inside the support block 11, causing the first spring 14 to deform accordingly. When the rotating plate 8 is rotated to a vertical state, the insertion rod 12 is aligned with the hole on the first sliding ring 13, and then the insertion rod 12 can be inserted into the housing 3 under the action of the elastic force of the first spring 14, thereby limiting the vertical state of the rotating plate 8.

[0041] Example 2:

[0042] The fixing device provided in Example 1 is further optimized, specifically, as Figure 5-Figure 6As shown, the fixing mechanism 7 includes a fixing block 15, a sliding assembly, and a blocking assembly. The fixing block 15 is fixedly connected between the two adjacent housings 3 and the two adjacent sliding columns 4.

[0043] The sliding assembly includes a connecting column 16 and a clamping block 17. The inner wall of the fixed block 15 is slidably connected to two connecting columns 16. One end of the two connecting columns 16 close to the middle of the receiving plate 1 is fixedly connected to the outer wall of the clamping block 17. The sliding between the connecting column 16 and the fixed block 15 correspondingly adjusts the position of the clamping block 17, so that the clamping block 17 is tightly attached to the oxygen tank, thereby clamping the oxygen tank.

[0044] The blocking assembly includes a limiting rack 18, the inner wall of the fixed block 15 is slidably connected with a limiting rack 18, and the limiting rack 18 is fixedly connected to the outer wall of the clamping block 17. The cross-section of the teeth at the top of the limiting rack 18 is a right triangle. The inner wall of the fixed block 15 is slidably connected with a baffle 19, and the bottom of the baffle 19 is provided with an inclined surface. The outer wall of the baffle 19 is fixedly connected with a second sliding ring 20, and the second sliding ring 20 is slidably connected to the inner wall of the fixed block 15. The outer side of the fixed block 15 is provided with a second spring 21, and the two ends of the second spring 21 are respectively fixedly connected to the outer wall of the second sliding ring 20 and the inner wall of the fixed block 15. When the inclined surface of the baffle 19 and the inclined surface of the teeth on the limiting rack 18 squeeze each other, the baffle 19 can be moved upward. When the vertical surface on the baffle 19 is in close contact with the vertical surface of the teeth on the limiting rack 18, the tooth is immediately restricted from moving in the direction of squeezing the vertical surface of the baffle 19.

[0045] Through the above structural design, the limiting screw 5 can be made to leave the corresponding sliding column 4 by rotating the two adjacent front and rear limiting screws 5, and then the position of the sliding column 4 in the housing 3 can be adjusted, and then the height of the corresponding two fixing mechanisms 7 can be adjusted accordingly, and then oxygen tanks of different specifications can be clamped at corresponding appropriate heights. When clamping the oxygen tank, the connecting column 16 or the limiting rack 18 is pushed toward the position where the oxygen tank is located. In this process, the inclined surface of the teeth on the limiting rack 18 will squeeze the inclined surface of the baffle 19, and then the baffle 19 will move upward accordingly, so that the limiting rack 18 can slide inside the fixed block 15, and the clamping block 17 is tightly attached to it. The oxygen tank can be clamped by the outside of the oxygen tank. Due to the restriction between the vertical surface of the baffle 19 and the vertical surface of the teeth on the limiting rack 18, the limiting rack 18 cannot move directly in the direction away from the oxygen tank. When the clamping of the oxygen tank needs to be released, the baffle 19 can be pulled upward to make the second sliding ring 20 slide inside the fixed block 15, so that the second spring 21 is deformed, which can limit the rack 18 inside the bottom of the baffle 19, thereby releasing the restriction on the limiting rack 18, and then the limiting rack 18 can drive the clamping block 17 to leave the outside of the oxygen tank. The baffle 19 and the limiting rack 18 are operated one by one to release the restriction on the oxygen tank.
