[0030] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0031] See Figure 1 , Figure 2 The telescopic flashlight device provided in this embodiment includes a telescopic component 100, a drive component 200, and a manual adjustment component 300.

[0032] The telescopic component 100 has a telescopic end. The drive component 200 is connected to the telescopic component 100 to drive the telescopic end to move.

[0033] The manual adjustment component 300 is connected to the drive component 200. An input end 321 is provided on one side of the manual adjustment component 300. The input end 321 rotates to drive the telescopic end to move through the drive component 200.

[0034] In this embodiment, the telescopic component 100 is the actuator of the integrated hand-flash telescopic device. The telescopic end can be connected to the landing gear or other structures of the transfer machine to adjust the height of the landing gear. The drive component 200 is connected to the telescopic component 100 for transmission, and the telescopic end can be driven to perform linear motion by controlling the drive component 200.

[0035] Furthermore, in this embodiment, the manual adjustment component 300 is connected to the drive component 200 via a transmission connection. When the power supply is depleted or power is unavailable, the input terminal 321 can be rotated, and the drive component 200 can be used to make the telescopic end move linearly. This eliminates the need to manually operate the telescopic component 100 to move the telescopic end, and the rotation position remains unchanged, making operation very convenient and less strenuous.

[0036] In this embodiment, the telescopic assembly 100 includes a rotating member 110 and a moving member 120.

[0037] The rotating component 110 is connected to the drive assembly 200 via a transmission connection. One end of the moving component 120 is the telescopic end, and the other end is threadedly connected to the drive assembly 200.

[0038] Specifically, in this embodiment, the screw drive structure formed by the rotating member 110 and the moving member 120 is used to drive the telescopic end. The rotating member 110 rotates under the drive of the drive assembly 200, and the moving member 120 moves along the axial direction of the rotating member 110 under the rotation of the rotating member 110 in combination with the thread characteristics, thereby driving the telescopic end.

[0039] In this embodiment, the drive assembly 200 includes a drive motor 210 and a transmission component 220. The drive motor 210 is connected to the rotating component 110 via the transmission component 220.

[0040] In this embodiment, the drive motor 210 is connected to the rotating component 110 via the transmission component 220 to ensure the smooth transmission of kinetic energy.

[0041] Specifically, in this embodiment, the drive motor 210 is disposed on one side of the transmission component 220, and the rotating shaft of the drive motor 210 is horizontally disposed and the rotating component 110 is used to drive the rotation of the rotating component 110.

[0042] In this embodiment, the manual adjustment component 300 includes an adapter 310 and a commutator 320.

[0043] One end of the adapter 310 is connected to the transmission member 220 to drive the transmission member 220 to rotate. The commutator 320 has a rotation input end 321, which is located on the side of the commutator 320. One end of the commutator 320 has an extended rotating part, which is connected to the input end 321 and to the other end of the adapter 310.

[0044] In this embodiment, the output end of the commutator 320 is located on the side of the commutator 320. The rotating part is driven to rotate by rotating the input end 321 of the commutator 320. The adapter 310 is used for the transmission connection between the rotating part and the transmission member 220, so that the rotating part can drive the transmission member 220 to rotate together, thereby driving the rotating member 110 to rotate, and then driving the telescopic end to move.

[0045] It should be noted that the adapter 310 and commutator 320 in this embodiment are conventional parts in the prior art that can be directly purchased and are commonly used parts in this field, so they will not be described in detail here.

[0046] In this embodiment, the two ends of the adapter 310 are respectively provided with a first adapter sleeve and a second adapter sleeve.

[0047] The first adapter sleeve is adapted to the end of the transmission component 220, and is sleeved on the outside of the end of the transmission component 220. The second adapter sleeve is adapted to the rotating part of the commutator 320, and is sleeved on the outside of the rotating part.

[0048] The first adapter sleeve and the transmission component 220, and the second adapter sleeve and the rotating part are detachably connected.

[0049] Specifically, in this embodiment, the rotating part 110 has a transmission end near the adapter 310. The transmission end has an outward convex structure, and the cross-sections of the transmission end, the rotating part, and the adapter 310 are all hexagonal.

[0050] The transmission end and the rotating part are respectively adapted to the first adapter sleeve and the second adapter sleeve, and the first adapter sleeve and the second adapter sleeve are respectively sleeved on the outside of the transmission end and the rotating part.

[0051] Furthermore, after the rotating member 110, the adapter 310 and the rotating part are detachably connected, the rotating member 110, the adapter 310 and the rotating part can rotate synchronously, so that the commutator 320 can drive the rotating member 110 to rotate and drive the telescopic end to move.

[0052] In this embodiment, the first adapter sleeve and the transmission component 220, and the second adapter sleeve and the rotating part are both connected by screws.

[0053] Specifically, in this embodiment, both the first and second adapter sleeves are provided with through holes, and correspondingly, the transmission end and the rotating part are provided with positioning holes opposite to the through holes. After the screw passes through the through hole, it is inserted into the positioning hole so that the rotating part 110, the adapter 310 and the rotating part can be detachably connected, thereby enabling synchronous rotation.

[0054] In this embodiment, the cross-sections of the first adapter sleeve, the second adapter sleeve, the transmission member 220, and the rotating part are all regular hexagons.

[0055] The faceted meshing structure formed by the regular hexagonal cross-section effectively increases the contact area, achieving uniform torque transmission through six symmetrically distributed force-bearing surfaces. Compared to circles or other polygons, the hexagonal structure avoids stress concentration during transmission, significantly reducing the risk of slippage.

[0056] It should be noted that in this embodiment, the manual adjustment component 300 is provided with a protective cover, which covers the transmission end, commutator 320 and adapter 310 to protect the three components.

[0057] In this embodiment, the transmission component 220 is a worm gear transmission structure.

[0058] The worm gear has a self-locking characteristic. After the position of the telescopic end is adjusted, it can be locked by the self-locking characteristic of the worm gear.

[0059] The unique helix angle design of the worm gear structure creates a unidirectional transmission characteristic. When the drive motor 210 stops supplying power, the friction angle between the worm and the worm wheel is greater than the helix angle, which automatically triggers the mechanical self-locking function. This feature effectively prevents the telescopic end from unexpectedly retracting due to the load during power outages or manual adjustments, meeting the stringent requirements of medical transfer machines for patient safety.

[0060] In this embodiment, the integrated telescopic flashlight device also includes a crank handle. One end of the crank handle is adapted to the input terminal 321, and the other end is provided with a hand cranking mechanism for manual operation.

[0061] Specifically, in this embodiment, one end of the crank handle is a rotating end and is used to insert into the input end 321. The cross-sectional shape of the rotating end in this embodiment is the same as that of the input end 321, which is a regular hexagon. This can effectively avoid stress concentration and reduce the risk of slippage. In addition, the regular hexagon has high torsional strength, making it more robust and durable when cranking, and less prone to deformation.

[0062] See Figure 3 The nursing transfer machine provided in this embodiment includes a support mechanism 400, a lifting assembly 500, and a provided hand-flash telescopic device.

[0063] The support mechanism 400 has multiple casters, and one end of the support mechanism 400 extends upward and is provided with a connecting part. One end of the lifting assembly 500 is hinged to the connecting part for vertical rotation, and the other end is a lifting end used to connect the tool supporting the patient. A telescopic hand-held device is mounted on and hinged to the support mechanism 400. The telescopic end of the telescopic hand-held device is hinged to the lifting assembly 500. The hinge axes of the lifting assembly 500 and the connecting part, the hinge axis of the telescopic hand-held device and the support mechanism 400, and the hinge axis of the telescopic hand-held device and the lifting assembly 500 are parallel to each other.

[0064] Specifically, in the transfer machine provided in this embodiment, the support machine supports the lifting assembly 500 and the integrated telescopic device of the hand and electric motor. The bottom of the support mechanism 400 is provided with multiple moving wheels to facilitate the movement of the transfer machine.

[0065] Furthermore, in this embodiment, the lifting assembly 500 is mounted on and hinged to the connecting portion at the top of the support mechanism 400, allowing the lifting assembly 500 to rotate along the connecting portion. The integrated telescopic flashlight device is mounted on and hinged to the support mechanism 400, allowing the integrated telescopic flashlight device to rotate along the hinge point. The telescopic end of the integrated telescopic flashlight device is hinged to the lifting assembly 500. The lifting assembly 500, the integrated telescopic flashlight device, and the support mechanism 400 form a stable triangular structure to ensure structural strength during use.

[0066] In use, the telescopic end can be driven upward by the drive component 200, thereby pushing the lifting component 500. The lifting component 500 rotates at its hinge point with the support mechanism 400 under this push, achieving a lifting and lowering action. When manually adjusting the height of the lifting end, the drive component 200, which is to be connected, can be driven by the manual adjustment component 300, thereby causing the lifting component 500 to move. This allows the lifting end of the lifting component 500 to be height-adjusted under the action of the manual adjustment component 300, eliminating the need for manual adjustment of the telescopic component 100. Furthermore, the point of force application remains unchanged due to the lifting and lowering action, making operation convenient and less strenuous.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
