DETAILED DESCRIPTION

[0030] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0031] As Figures 1 to 4 shown, the utility model discloses a stretcher car oxygen cylinder fixing device, which comprises:

[0032] The mounting seat 1 is provided with mounting holes 11 connected with the stretcher car through fixing pieces;

[0033] The cylinder 2 is installed on the mounting seat 1 and is used for accommodating oxygen cylinders;

[0034] A plurality of arc plates 3 are arranged in the cylinder 2 and are uniformly and interval distributed along the circumference, the inner wall of each arc plate 3 is provided with an anti-skid layer, and a gap is arranged between the outer wall of the arc plate 3 and the inner wall of the cylinder 2;

[0035] A plurality of damping assemblies 4 are arranged between each arc-shaped plate 3 and the cylinder 2 respectively;

[0036] The stretcher usually needs to have the functions of quick unfolding and folding to adapt to different use scenarios. By installing the mounting seat 1 at the middle position of the cross rod below the bed surface of the stretcher, the compatibility between the oxygen cylinder fixing and the use of the frame is ensured, which not only improves the space utilization of the stretcher, but also enhances the practicability and emergency response capability of the stretcher. When the oxygen cylinder is placed in the cylinder 2, a plurality of arc-shaped plates 3 surround the oxygen cylinder and tightly adhere to the outer surface of the oxygen cylinder through the anti-slip layer on the inner side, so as to effectively fix the oxygen cylinder. During the driving of the stretcher, the damping assembly 4 absorbs energy by compression deformation, thereby reducing the vibration and impact force transmitted to the oxygen cylinder and protecting the oxygen cylinder from possible physical damage. This design provides a safer and more reliable oxygen cylinder fixing scheme for emergency or patient transfer.

[0037] The damping assembly 4 includes an annular groove 41 arranged in the side wall of the cylinder 2, a plurality of second sliding plates 42 for left and right movement are arranged in the annular groove 41, the two sides of the second sliding plate 42 are respectively provided with a second elastic member 43 connected with the side wall of the annular groove 41 and a second connecting rod 44 connected with the side wall of the arc-shaped plate 3, and a through hole is formed in the cylinder 2 for the second connecting rod 44 to pass through;

[0038] The annular groove 41 provides a moving space for the second sliding plate 42. When the stretcher encounters vibration or impact, these external forces are transmitted to the second connecting rod 44 through the arc-shaped plate 3, and then the second sliding plate 42 moves in the annular groove 41 along the direction of the force. The second elastic member 43 is usually a spring or other elastic material. When the second sliding plate 42 moves, the second elastic member 43 deforms to store energy, and returns to the original position after the external force disappears, thereby effectively reducing the impact force transmitted to the oxygen cylinder. This process not only protects the oxygen cylinder from direct impact, but also reduces the cumulative damage to the oxygen cylinder that may occur during long-term transportation.

[0039] Preferably, a plurality of second sliding plates 42 are connected to the slide rod 45 in sequence, the two sides of the slide rod 45 are respectively provided with a slide sleeve 46, and the upper and lower sides of the annular groove 41 are respectively provided with a guide rod 47, and the slide sleeve 46 and the guide rod 47 are in sliding fit. By means of the slide rod 45, the movements of all the second sliding plates 42 are synchronized to ensure that all the damping points respond at the same time and improve the damping efficiency. The sliding fit mechanism of the slide sleeve 46 and the guide rod 47 ensures the linearity and stability of the slide rod 45 and the second sliding plates 42 thereon during movement, preventing unnecessary lateral displacement, thereby reducing friction loss and prolonging the service life of the damping assembly.

[0040] Preferably, the cylinder 2 is arranged obliquely, with its open end facing the higher side at an oblique angle to the horizontal plane, and a buffer pad 5 is arranged on the inner bottom of the cylinder 2; by arranging obliquely, when the oxygen cylinder needs to be put in or taken out, the operator can more easily control the direction and force of the oxygen cylinder, reducing the difficulty and time of operation; at the same time, the oblique cylinder 2 makes the oxygen cylinder naturally lean towards the lower end of the lower side when placed, and the damping assembly 4 and the buffer pad 5 keep stability.

[0041] As shown in Figures 5 to 8 The cylinder 2 is composed of two mutually independent half-shells 21, the bottom ends of the two half-shells 21 are rotationally connected by a rotating shaft 22, and the top ends of the two half-shells 21 are connected by a locking member 23.

[0042] The relative rotation between the half-shells 21 is allowed by the rotating shaft 22, which enables the cylinder 2 to switch between open and closed states; when the oxygen cylinder needs to be placed or taken out, the operator can unlock the locking member 23, then rotate the upper half-shell 21 around the rotating shaft 22 to open the cylinder 2, at which time the oxygen cylinder can be handled without obstacles, and after the oxygen cylinder is placed, the two half-shells 21 are closed and fixed by the locking member 23, ensuring that it will not be accidentally opened during transportation and ensuring that the oxygen cylinder remains stable throughout the transportation process.

[0043] Preferably, the locking member 23 includes a protrusion 231 arranged on one of the half-shells 21 and a groove 232 arranged on the other half-shell 21, the groove 232 cooperates with the protrusion 231, the protrusion 231 is provided with a mounting slot, a first sliding plate 233 is slidably arranged in the mounting slot, the side of the first sliding plate 233 away from the groove 232 is connected to the inner wall of one side of the mounting slot by a first elastic member 234, and the side wall of the first sliding plate 233 close to the groove 232 is fixedly connected with a wedge-shaped block 235, and the groove 232 is provided with a wedge-shaped groove cooperating with the wedge-shaped block 235.

[0044] The mounting slot provides a space for the first sliding plate 233, the first elastic member 234 and the wedge-shaped block 235, the first elastic member 234 is usually a spring or other elastic material, which provides a restoring force to enable the first sliding plate 233 to remain in the initial position when not subject to external force; when the two half-shells 21 are closed, the protrusion 231 is inserted into the groove 232, during the insertion process, the wedge-shaped block 235 will first contact the edge of the wedge-shaped groove in the groove 232, due to the wedge-shaped design, the wedge-shaped block 235 will be gradually pushed into the mounting slot, compressing the first elastic member 234; as the protrusion 231 is completely inserted into the groove 232, the wedge-shaped block 235 reaches the position of the wedge-shaped groove, under the restoring action of the first elastic member 234, the wedge-shaped block 235 automatically pops out and embeds into the wedge-shaped groove, completing the locking.

[0045] Preferably, the inclined surface of the wedge-shaped block 235 faces the insertion direction of the protruding part 231; this design makes the insertion process smoother, reduces resistance, improves operational efficiency, ensures the reliability of the lock in combination with the resetting force provided by the first elastic member 234, and prevents accidental unlocking during transportation.

[0046] Preferably, the first sliding plate 233 is fixedly connected with a first connecting rod 236 on the side away from the groove 232, the first connecting rod 236 extends to the outside through the protruding part 231, and the distal end is provided with a handle 237; by pulling the handle 237 away from the groove 232, this will move the first sliding plate 233 through the first connecting rod 236, so that the wedge-shaped block 235 exits from the wedge-shaped slot, and the two half shells 21 are separated; this design makes the unlocking action more intuitive and easy, improving operational efficiency.

[0047] Preferably, the outer side of the rotating shaft 22 is sleeved with a torsional spring 24, the two branches of the torsional spring 24 are in contact with the mutually close surfaces of the half shell 21 and the rotating shaft 22, respectively, and a chain 25 is arranged between the half shell 21 and the rotating shaft 22 to limit the opening degree; when the two half shells 21 are closed, the torsional spring 24 is twisted and stores elastic potential energy, and the locking member 23 firmly fixes the two half shells together to prevent the torsional spring 24 from releasing energy; when the locking member 23 is unlocked, the energy stored by the torsional spring 24 is released, and the torsional spring applies a rotary torque to push the half shell 21 to rotate outward around the rotating shaft 22, so that the half shell 21 can be automatically opened, simplifying the operation process; the chain 25 limits the maximum opening angle to prevent structural damage caused by excessive opening, and also plays a buffering role, ensuring that the half shell 21 will not be violently opened due to the rapid release of energy by the torsional spring 24, and ensuring the safety of the operation.

[0048] The oxygen cylinder fixing device for stretcher car of the utility model, when working, firstly uses the fixing piece through the installation hole 11 to connect the whole device to the appropriate position of the stretcher car, unlocks the half shell 21, holds the handle 237, pulls the first connecting rod 236 in the direction away from the recess 232, makes the wedge block 235 exit from the wedge-shaped groove, completes the unlocking action, after unlocking, the torsional spring 24 releases the stored energy, automatically pushes the half shell 21 to rotate outward around the rotating shaft 22, until reaches the maximum opening angle set by the chain 25, places the oxygen cylinder into the cylinder body 2, ensures that the bottom contacts the buffer pad 5, pushes back the half shell 21, makes it close around the rotating shaft 22, at this time, the torsional spring 24 is gradually compressed or twisted, stores the elastic potential energy, when the two half shells 21 close, the protruding part 231 inserts into the recess 232, the wedge block 235 is gradually pushed into the installation groove under the pressure in the inserting process, simultaneously compresses the first elastic piece 234, along with the increase of the insertion depth, the wedge block 235 finally reaches the wedge-shaped groove position, at this time, under the reset action of the first elastic piece 234, the wedge block 235 automatically pops out and embeds into the wedge-shaped groove, completes the locking, when the stretcher car meets the vibration or impact in the transportation process, the arc-shaped plate 3 moves, drives the second sliding plate 42 and the sliding rod 45 connected with it to move as a whole along the direction of the guide rod 47, the second elastic piece 43 is compressed or stretched, stores the energy brought by the external force, once the external force disappears or weakens, the second elastic piece 43 releases the stored energy, pushes the sliding rod 45 and the second sliding plate 42 back to the original position, effectively reduces the impact force transmitted to the oxygen cylinder.

[0049] The oxygen cylinder fixing device for stretcher car of the utility model, its installation mode, connection mode or setting mode are all common mechanical modes, as long as the beneficial effects can be achieved, can be implemented.

[0050] The above only is the preferred implementation mode of the utility model, it should be pointed out that, for the ordinary skilled person in the prior art, on the premise of not departing from the technical principle of the utility model, can also make several improvements and variations, these improvements and variations also should be regarded as the protection scope of the utility model.
