DETAILED DESCRIPTION

[0029] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0030] See also Figure 1The present invention provides a cantilever stretcher vehicle, which includes a movable frame 10, a lifting mechanism 20 installed on the movable frame 10, a cantilever 30 arranged on the lifting mechanism 20, and a stretcher 40 installed on the cantilever 30. The movable frame 10 plays a role in supporting and moving the entire cantilever stretcher vehicle, and the lifting mechanism 20 plays a role in lifting the stretcher 40 to meet the use needs of medical staff.

[0031] The movable frame 10 is formed by a plurality of frame rods connected to each other, and a plurality of universal wheels 11 are installed at the bottom of the movable frame 10 to facilitate the cantilever stretcher vehicle to move in all directions.

[0032] Please also see Figure 2 and Figure 3 The lifting mechanism 20 includes a compression cylinder 21 connected to the movable frame 10 and a lifting sleeve 22 installed on the compression cylinder 21. Specifically, the cylinder end of the compression cylinder 21 is connected to the movable frame 10, and the lifting sleeve 22 is generally a hollow cylindrical structure with an opening at the lower end. The telescopic end of the compression cylinder 21 is connected to the top of the lifting sleeve 22 and is accommodated in the interior of the lifting sleeve 22, so that the lifting sleeve 22 can move up and down with the telescopic end of the compression cylinder 21, and during the lifting and moving process of the lifting sleeve 22, the cylinder end of the compression cylinder 21 is at least partially accommodated in the lifting sleeve 22, which prevents medical staff from accidentally touching the telescopic end of the compression cylinder 21 and also plays a role in aesthetics.

[0033] In this embodiment, the compression cylinder 21 is a hydraulic cylinder, which can achieve a large power output in a small volume, saving space while meeting the use needs of medical staff. It can be understood that in other embodiments not shown, the compression cylinder 21 can also be a gas cylinder, the working medium of the gas cylinder is easy to obtain, energy-saving and environmentally friendly, and conducive to controlling production costs.

[0034] In addition, in order to facilitate medical staff to move the cantilever stretcher, a pushing handrail 221 is provided on the lifting sleeve 22 .

[0035] In this embodiment, the cantilever 30 is roughly in a "Z"-shaped structure. The cantilever 30 includes a connecting rod 31 and a suspension rod 32 and a suspension plate 33 respectively connected to both ends of the connecting rod 31, wherein the connecting rod 31 is roughly vertically arranged, the suspension rod 32 and the suspension plate 33 are horizontally arranged, the suspension rod 32 is connected to the lifting sleeve 22 of the lifting mechanism 20, and the suspension plate 33 is connected to the stretcher 40, and the connection between the suspension plate 33 and the stretcher 40 is lower than the connection between the suspension rod 32 and the lifting sleeve 22. When the lifting mechanism 20 is working, the stretcher 40 is lifted and lowered together with the lifting sleeve 22 by the action of the cantilever 30, so as to adjust the height of the stretcher 40. Since the stretcher 40 is connected to the suspension plate 33 at a lower position relative to the suspension rod 32, it is ensured that the center of gravity of the stretcher 40 can be lower than the top of the telescopic end of the compression cylinder 21, thereby enhancing the stability of the stretcher 40 during movement, reducing the shaking degree of the stretcher 40, and playing a role in safety protection for the patient.

[0036] Furthermore, a space (not shown) is formed between the lifting sleeve 22 and the connecting rod 31. When the patient needs a bath, there is no need to move the patient off the stretcher 40. When the compression cylinder 21 is directly operated, the stretcher 40 is in a higher position, and then a bathtub is placed under the stretcher 40. The compression cylinder 21 is operated to descend, so that the side wall of the bathtub is embedded in the space. At this time, the patient is also in the bathtub to take a bath, which is convenient to operate.

[0037] It is understandable that in other embodiments not shown, it is sufficient that the end of the cantilever 30 connected to the stretcher 40 is lower than the end connected to the lifting sleeve 22, and the specific shape of the cantilever 30 is not limited here.

[0038] It is also understandable that in other embodiments not shown, the lifting sleeve 22 may be omitted. In this case, the suspension rod 32 of the cantilever 30 is directly connected to the telescopic end of the compression cylinder 21 .

[0039] See also Figure 4 The stretcher 40 includes a fixing frame 41 mounted on the hanging plate 33 and a support frame (not shown) hinged on the fixing frame 41, and the support frame includes an upper support frame 42 and a lower support frame 43. Specifically, the upper support frame 42 is hinged at one end of the fixing frame 41 to support the patient's back, and the lower support frame 43 is hinged at the other end of the fixing frame 41 relative to the lower support frame 42 to support the patient's legs. In order to adjust the angle of the upper support frame 42 and the lower support frame 43 so that the patient can have a more comfortable lying position, an adjustment component 44 is provided between the hanging plate 33 and the upper support frame 42 and between the hanging plate 33 and the lower support frame 43.

[0040] Please also see Figure 5-Figure 9Specifically, the adjustment assembly 44 includes a sleeve 441, a slide rod 442 slidably disposed in the sleeve 441, a locking member 443 rotatably mounted on the slide rod 442, and a blocking member 444 mounted on the sleeve 441.

[0041] The sleeve 441 is generally a hollow tubular structure with an opening at one end, and the end of the sleeve 441 opposite to the opening is hinged to the suspension plate 33. One end of the slide bar 442 is accommodated in the sleeve 441, and the other end of the slide bar 442 passes through the open end of the sleeve 441 and is hinged to the support frame. In this embodiment, a locking groove 4411 and a stop groove 4412 are respectively provided on two opposite side walls of the sleeve 441, and the locking groove 4411 is provided on the top wall of the sleeve 441, and the stop groove 4412 is provided on the bottom wall of the sleeve 441. The blocking member 444 is detachably mounted on the outer wall of the sleeve 441 corresponding to the blocking groove 4412, and the blocking member 444 partially passes through the blocking groove 4412 and extends to the interior of the sleeve 441. The locking groove 4411 is located on the side of the blocking member 444 away from the opening of the sleeve 441, and the locking member 443 is rotatably mounted on one end of the slide rod 442. The rotation center of the locking member 443 is higher than the top of the blocking member 444. When the locking member 443 moves to abut against the blocking member 444 under the drive of the slide rod 442, the locking member 443 can rotate under the blocking action of the blocking member 444, so that one end of the locking member 443 passes through the locking groove 4411 and rotates to the outside of the sleeve 441.

[0042] In this embodiment, the locking member 443 is substantially in the shape of a rectangular plate, and two sides of the locking member 443 along the width direction are provided with locking grooves 4431 .

[0043] See also Figure 6 and Figure 7 When the medical staff needs to lift the support frame (that is, when the sliding rod 442 is stretched), the support frame needs to be rotated upward first. At this time, the sliding rod 442 drives the locking member 443 to slide from the sleeve 441 in the extending direction. When sliding to the point where the locking groove 4431 at one end of the locking member 443 contacts the stopper 444, the locking member 443 rotates, and the end of the locking member 443 away from the stopper 444 extends out of the locking groove 4411. When the opening of the locking groove 4431 is aligned with the groove wall of the locking groove 4411 away from the opening end of the sleeve 441, the support frame is pressed down, and the locking groove 4431 is clamped with the groove wall of the locking groove 4411. At this point, the support frame is locked and cannot be pressed down further, thereby fixing the support frame at a suitable angle.

[0044] See also Figure 8 and Fig. 9When the medical staff needs to put down the support frame (i.e., when the slide bar 442 is compressed), the support frame needs to be rotated upward first, so that the slide bar 442 moves outward by one end until one end of the locking member 443 is blocked by the blocking member 444 and rotates. At this time, the locking groove 4431 of the locking member 443 is separated from the groove wall of the locking groove 4411, and the support frame is unlocked. Then the support frame is pressed down, and the locking member 443 is driven by the slide bar 442 to extend into the sleeve 441, thereby resetting the support frame. The above operation is simple and convenient, and can realize the self-locking function, thereby improving the work efficiency of medical staff.

[0045] Furthermore, since the retaining member 444 is detachably connected to the sleeve 441, it can be easily disassembled, which is beneficial for maintaining and replacing the retaining member 444 and the locking member 443. In this embodiment, the retaining member 444 is connected to the sleeve 441 by bolts (not shown).

[0046] In addition, the slide bar 442 on the adjustment assembly 44 between the suspension plate 33 and the upper support frame 42 is hinged on the lower surface of the upper support frame 42, and the slide bar 442 on the adjustment assembly 44 between the suspension plate 33 and the lower support frame 43 is hinged on the lower surface of the lower support frame 43.

[0047] It is understandable that in other embodiments not shown, the adjustment component 44 may also be a cylinder.

[0048] Specifically, the cylinder body end of the cylinder is hinged on the suspension plate 33, and the telescopic end of the cylinder can be slidably embedded in the lower surface of the support frame. The rotation angle of the support frame is adjusted by the telescopic movement of the telescopic end of the cylinder, and the angle adjustment function of the support frame can also be realized. Specifically, the telescopic end of the cylinder between the suspension plate 33 and the upper support frame 42 can be slidably embedded in the lower surface of the upper support frame 42, and the telescopic end of the cylinder between the suspension plate 33 and the lower support frame 43 can be slidably embedded in the lower surface of the lower support frame 43.

[0049] In this embodiment, the suspension plate 33 is detachably connected to the fixing frame 41, so that medical personnel can replace stretchers 40 of different specifications according to usage needs, thereby improving the applicability of the cantilever stretcher vehicle.

[0050] Please refer again Figure 1In this embodiment, in order to prevent the patient from sliding down from the upper support frame 42 to the lower support frame 43, a hand support 421 is provided on the upper support frame 42, and a foot support 431 is provided on the lower support frame 43. At the same time, in order to meet the needs of the patient's head resting on the upper support frame 42, a headrest 422 is slidably provided on the upper surface of the upper support frame 42. In a specific embodiment, a protrusion (not shown) is provided on the headrest 422, and a groove (not shown) is provided on the upper surface of the upper support frame 42. The position of the headrest 422 is adjusted by the sliding fit connection between the protrusion and the groove. It can be understood that in other embodiments not shown, the protrusion can also be provided on the upper support frame 42, and the groove can be provided on the headrest 422.

[0051] In order to prevent the patient from sliding off the side of the stretcher 40 , guard plates 46 are hinged on opposite sides of the fixing frame 41 . When in use, the patient can be clamped between the two guard plates 46 to prevent the patient from sliding off.

[0052] See also Fig.10 In this embodiment, a flip assembly 47 is provided between the fixing frame 41 and the guard plate 46 , and the guard plate 46 is connected to the fixing frame 41 through the flip assembly 47 .

[0053] Please also see Fig.11 and Fig.12 Specifically, the flip assembly 47 includes a pair of fixed plates 471 fixedly connected to the fixed frame 41, a fixed sleeve 472 connected to one of the connecting plates 471, a stopper 473 slidably passing through the fixed plate 471, a rotating member 474 rotatably sleeved on the outside of the stopper 473, and an elastic member 475 telescopically arranged on the side of the stopper 473.

[0054] The fixing plates 471 are arranged opposite to each other, and the two ends of the fixing sleeve 472 are arranged through. The two fixing plates 471 are provided with oppositely arranged engaging grooves 4711 on the opposite surfaces. One end of the stopper 473 passes through the engaging groove 4711 and extends to the outside of one end of the fixing sleeve 472. The stopper 473 is generally in a columnar structure. The upper part of the side wall of the stopper 473 is provided with an engaging portion 4731 that matches the engaging groove 4711. The engaging portion 4731 is slidably engaged in the engaging groove 4711, so that the stopper 473 can only slide along the axial direction of the stopper 473 and cannot rotate relative to the fixing plate 471. At the same time, in order to prevent any end of the stopper 473 from being separated from the fixing plate 471 or the fixing sleeve 472, one end of the stopper 473 is provided with a first abutting portion 4732 that can abut the fixing plate 471, and the other end of the stopper 473 is provided with a second abutting portion 4733 that can abut the fixing sleeve 472.

[0055] In this embodiment, a rotating portion 4734 is further provided on the side wall of the stopper 473 at one side of the engaging portion 4731 , and the cross-sectional dimension of the rotating portion 4734 is smaller than the cross-sectional dimension of the engaging portion 4731 .

[0056] The rotating member 474 is generally in a plate-like structure, and the guard plate 46 is fixedly mounted on the rotating member 474. The rotating member 474 is sandwiched between the two fixed plates 471, and a through hole 4741 is provided on the rotating member 474 to cooperate with the engaging portion 4731. It can be understood that the cross-sectional size of the rotating portion 4734 is smaller than the cross-sectional size of the through hole 4741. When the moving stopper 473 is at least partially engaged with the engaging portion 4731 and the through hole 4741, the circumferential direction of the rotating member 474 is positioned and cannot rotate relative to the stopper 473; when the moving stopper 473 is completely separated from the engaging portion 4731 and the through hole 4741, the rotating portion 4734 is aligned with the through hole 4741, and the rotating member 474 can rotate relative to the stopper 473.

[0057] In this embodiment, the cross section of the engaging portion 4731 is a square, and the cross section of the rotating portion 4734 is an inscribed circle in the positive direction, so that the rotating member 474 can be locked again by the sliding stopper 473 every time the rotating member 474 rotates 90°. It can be understood that in other embodiments not shown, the cross section of the engaging portion 4731 is a regular polygon, and the cross section of the rotating portion 4734 is an inscribed circle of the regular polygon, and the rotating member 474 can be locked again every time it rotates (360 / number of sides of the regular polygon)°.

[0058] Furthermore, the elastic member 475 is accommodated in the fixing sleeve 472, one end of the elastic member 475 elastically abuts against one end of the fixing sleeve 472, and the other end of the elastic member 475 elastically abuts against the engaging portion 4731. When the elastic member 475 is in a natural state, the engaging portion 4731 at least partially cooperates with the through hole 4741, and at this time, the rotating member 474 cannot rotate. When the stopper 473 is pressed until the rotating portion 4734 is aligned with the through hole 4741, the rotating member 474 can drive the guard plate 46 to rotate. When the medical staff releases the pressure on the stopper 473, the stopper 473 can be reset under the elastic force of the elastic member 475, and the operation is simple and quick.

[0059] In this embodiment, the elastic member 475 is a spring mounted on the outside of the stop member 473. It can be understood that in other embodiments not shown, the elastic member 475 can also be an elastic and rigid element such as a thin steel sheet, which is not limited here.

[0060] The following describes the use process of the cantilever stretcher vehicle of the present invention in conjunction with the accompanying drawings:

[0061] After the patient lies on the stretcher 40 and is clamped by the guard plate 46, the stretcher 40 is adjusted to a suitable height by the lifting mechanism 20 and then pushed to a designated location. When the patient needs to be transferred to another stretcher, it is only necessary to adjust the stretcher to a suitable height and release the clamping effect of the guard plate 46 on the patient, so that the patient can be transferred conveniently.

[0062] The cantilever stretcher trolley provided by the present invention has an end of the cantilever 30 connected to the stretcher 40 that is lower than the end connected to the lifting sleeve. Compared with the traditional stretcher trolley, the height of the center of gravity of the stretcher 40 is lowered, the stability of the stretcher 40 during movement is improved, and the shaking degree of the stretcher 40 is reduced. The cantilever stretcher trolley is safe and reliable, and the pain of the patient is alleviated. It has a simple structure and is easy to operate, and is suitable for popularization and use.

[0063] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the scope of the present invention through the above description.
