Description

Technical Field

[0001] This application relates to the field of incubator transport, and in particular to a shock-absorbing mechanism and a transport vehicle. Background Technology

[0002] Incubators, as devices with multiple functions such as cooling, heating, heat preservation, and humidity control, are used in various industries including biology, medicine, and environmental protection. One type of infant transport incubator is primarily suitable for the intra- or inter-hospital transport of newborns, premature infants, and sick children. The main function of the infant transport incubator is to provide heat preservation, humidity control, and oxygen supply during transport within and outside children's hospitals.

[0003] Currently, transport incubators on the market rely on mattresses and transport vehicles for shock absorption to reduce the degree of bumps during transport. However, during long-distance transport in ambulances, the incubators experience prolonged bumps, and existing systems that rely solely on mattresses for shock absorption are not effective enough. Utility Model Content

[0004] To reduce the vibration and improve the stability of the incubator during transportation, this application provides a shock absorption mechanism and a transport vehicle.

[0005] On the one hand, the shock absorption mechanism provided in this application adopts the following technical solution: A shock-absorbing mechanism includes a positioning seat, a base disposed at the bottom of the positioning seat, and a shock-absorbing spring disposed on the base. The bottom surface of the positioning seat has an expansion groove for the shock-absorbing spring to extend and retract vertically. The base is provided with a fixing bolt for connecting the positioning seat and the base. The shock-absorbing spring is sleeved on the fixing bolt, with one end of the shock-absorbing spring abutting against the positioning seat and the other end of the shock-absorbing spring abutting against the base.

[0006] By adopting the above technical solution, the positioning seat is used to contact the bottom of the incubator, the base is used to install the shock-absorbing spring, and the shock-absorbing spring is used to reduce the degree of bumps generated when the incubator moves; the telescopic groove is used for the positioning seat to move as the shock-absorbing spring is compressed, and the fixing bolt is used to connect the base and the positioning seat. The fixing bolt passes through the base and is threadedly connected to the positioning seat. The bolt head and the end thread are connected for positioning. When the shock-absorbing spring moves down, the fixing bolt moves down with it. When the shock-absorbing spring moves up to reset, the fixing bolt moves up with it.

[0007] Preferably, the width of the telescopic groove is larger than the width of the base.

[0008] By adopting the above technical solution, the width of the telescopic groove is larger than the width of the base, which facilitates the vertical movement of the positioning seat and reduces the interference of the base on the positioning seat.

[0009] Preferably, the base has a positioning groove on the side facing the shock-absorbing spring for positioning the end of the shock-absorbing spring, and the positioning seat has a protrusion located in the telescopic groove, and the upper end of the shock-absorbing spring is sleeved on the protrusion.

[0010] By adopting the above technical solution, the positioning groove improves the stability of the shock-absorbing spring between the base and the positioning seat, and the protrusion cooperates with the positioning groove to limit the shock-absorbing spring and improve the extension and contraction stability of the shock-absorbing spring.

[0011] Preferably, the base has a positioning hole for the fixing bolt to pass through, and the positioning seat has a threaded hole corresponding to the position of the positioning hole.

[0012] By adopting the above technical solution, the positioning hole is used for the fixing bolt to pass through, and at the same time, it is convenient for the fixing bolt to move according to the extension and contraction state of the shock-absorbing spring. The threaded hole is used for the fixing bolt to be fixedly connected to the positioning seat. The fixing bolt connects the base and the positioning seat through the thread of the bolt head and the end.

[0013] Preferably, the top surface of the positioning seat is provided with a fixing member.

[0014] By adopting the above technical solution, the fastener facilitates the subsequent connection between the shock absorption mechanism and the incubator.

[0015] On the other hand, the transfer vehicle provided in this application adopts the following technical solution: A transfer vehicle includes a transfer stretcher and a movable component disposed under the transfer stretcher. The load-bearing surface of the transfer stretcher is provided with any of the above-mentioned shock-absorbing mechanisms, and the transfer stretcher is provided with a positioning component for positioning the shock-absorbing mechanism.

[0016] By adopting the above technical solution, the moving component is used to drive the transfer stretcher to move, the transfer stretcher is used to carry the incubator, the shock absorption mechanism is used to improve the stability of the incubator on the transfer stretcher, and the positioning component is used to position the shock absorption mechanism on the transfer stretcher to improve the stability of the incubator on the transfer stretcher.

[0017] Preferably, the positioning component includes a positioning block and a driving member for moving the positioning block toward the shock absorption mechanism. The positioning seat has a slot on the side wall facing the positioning block, and the positioning block has a locking block located in the slot.

[0018] By adopting the above technical solution, the driving component is used to drive the positioning block to move toward the shock absorption mechanism, the positioning block is used to improve the stability of the shock absorption mechanism on the transfer stretcher, and the slot and the block improve the positioning effect of the positioning block on the positioning seat.

[0019] Preferably, the load-bearing surface of the transfer stretcher is provided with fixing blocks for positioning both ends of the positioning seat. The fixing blocks are inclined toward the side wall of the positioning seat, and the positioning seat is inclined toward the side wall of the fixing blocks, with the inclination direction consistent with the inclination direction of the side wall of the fixing blocks.

[0020] By adopting the above technical solution, the fixing block improves the stability of the positioning seat on the transfer stretcher. The fixing block and the end of the positioning seat are set at an angle, which makes it easy for the fixing block to adapt to the movement state of the positioning seat during shock absorption, and at the same time, it can also position the positioning seat.

[0021] In summary, the shock absorption mechanism effectively improves the stability of the incubator on the transport vehicle, while also facilitating the installation or disassembly of the incubator and effectively reducing the degree of bumps during long-distance transportation.

[0023] The following is in conjunction with the appendix Figures 1-7 The present invention will be further described below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and should not be used to limit the protection scope of the present invention.

[0024] In the description of this application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] This application discloses a shock absorption mechanism. (Refer to...) Figure 1 and Figure 2 The system includes a positioning seat 1, a base 2 located at the bottom of the positioning seat 1, and a shock-absorbing spring 3 mounted on the base 2 and located within the positioning seat 1. The bottom surface of the positioning seat 1 has a telescopic groove 4 for the shock-absorbing spring 3 to extend and retract vertically. The width of the telescopic groove 4 is larger than the width of the base 2. When the positioning seat 1 moves up and down with the shock-absorbing spring 3, the telescopic groove 4 effectively prevents the base 2 from interfering with the movement of the positioning seat 1. To improve the stability between the positioning seat 1 and the base 2, a fixing bolt 5 is installed on the base 2. The fixing bolt 5 includes a bolt head and a threaded rod. The end of the threaded rod away from the bolt head has an external thread. The base 2 has a positioning hole 8 for the fixing bolt 5 to pass through. The width of the positioning hole 8 is smaller than the width of the bolt head, but larger than the width of the threaded rod. The positioning seat 1 has a threaded hole 9 located above the positioning hole 8. The positioning seat 1 is threadedly connected to the fixing bolt 5 through the threaded hole 9, and the bolt head positions the base 2.

[0026] Reference Figure 2 and Figure 3 The shock-absorbing spring 3 is sleeved on the fixing bolt 5. One end of the shock-absorbing spring 3 abuts against the positioning seat 1, and the other end of the shock-absorbing spring 3 abuts against the base 2. When the shock-absorbing spring 3 is compressed, it drives the positioning seat 1 to move down. At this time, the fixing bolt 5 moves down through the positioning hole 8. When the shock-absorbing spring 3 returns to its original position, it drives the positioning seat 1 to return to its original position. At this time, the fixing bolt 5 returns to its original position, and the bolt head abuts against the base 2 again.

[0027] Reference Figure 2 and Figure 3 To improve the stability of the shock-absorbing spring 3 during extension and retraction, a positioning groove 6 is provided on the side of the base 2 facing the shock-absorbing spring 3, and the lower end of the shock-absorbing spring 3 is located in the positioning groove 6. A protrusion 7 is provided on the positioning seat 1, located within the extension groove 4 and at the center of the shock-absorbing spring 3, and the upper end of the shock-absorbing spring 3 is fitted onto the protrusion 7. The positioning groove 6, in conjunction with the protrusion 7, positions the shock-absorbing spring 3, improving the stability of its extension and retraction. To facilitate the connection between the shock-absorbing mechanism and the incubator, a fixing member 10 is installed on the top surface of the positioning seat 1. In this embodiment, the fixing member 10 is a bolt; in actual implementation, welding can be used to directly fix the positioning seat 1 to the bottom of the incubator; or the fixing member 10 can be installed using a detachable structure such as a snap-fit.

[0028] This application also discloses a transfer vehicle, as described in the embodiments. Figure 4 The system includes a transfer stretcher 11 and a moving assembly 12 mounted on the bottom surface of the transfer stretcher 11. In this embodiment, the moving assembly 12 uses a bracket and several casters mounted on the bottom of the support. The aforementioned shock-absorbing mechanism is mounted on the bearing surface of the transfer stretcher 11. This application provides two sets of shock-absorbing mechanisms, but multiple sets can be used as needed during implementation. A positioning assembly 13 is mounted on the transfer stretcher 11 to position the shock-absorbing mechanism and improve its stability.

[0029] Reference Figure 4 The positioning component 13 includes a positioning block 131 and a drive component 132 mounted on the transfer stretcher 11. The drive component 132 drives the positioning block 131 to reciprocate toward the positioning seat 1. The positioning seat 1 has a slot 14 on its side wall facing the positioning block 131. A locking block 15 is fixedly installed on the positioning block 131 within the slot 14. The width of the slot 14 in the height direction is larger than the width of the locking block 15 in the height direction, allowing the locking block 15 to adapt to the vertical movement of the positioning seat 1. When the shock absorption mechanism needs to be disassembled, the drive component 132 drives the positioning block 131 away from the positioning seat 1, thereby moving the locking block 15 out of the slot 14. In this embodiment, the drive component 132 uses a cylinder for linear movement. In actual implementation, to save costs, the drive component 132 uses a fixed rod and bolts. The fixed rod has several adjustment holes along the moving direction of the positioning block 131, and the fixing position of the bolts on the fixed rod is adjusted using the adjustment holes.

[0030] Reference Figure 4 The transport stretcher 11 has fixed blocks 16 at both ends of the positioning seat 1 fixedly installed on the bearing surface. The fixed blocks 16 are inclined towards the side wall of the end of the positioning seat 1, and the positioning seat 1 is inclined towards the slope of the fixed blocks 16, and the inclination direction is consistent with the inclination direction of the inclined surface of the fixed blocks 16. This effectively prevents the fixed blocks 16 from interfering with the positioning seat 1 when the positioning seat 1 moves up and down.

[0031] Reference Figure 5 , Figure 6 and Figure 7 When the incubator moves downward, it causes the shock-absorbing spring 3 to be compressed, buffering the downward force of the incubator and reducing the possibility of the baby being hit inside the incubator.

[0032] The shock absorption mechanism of this application effectively improves the stability of the incubator on the transport vehicle and reduces the degree of bumps generated by the incubator. At the same time, the transport vehicle of this application can perform shock absorption and positioning for incubators of different sizes, improving the adaptability and practicality of the transport vehicle.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
