[0031] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship 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 indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0033] The purpose of this invention is to provide a lifting module for a medical trolley that can reduce the size of the lifting module and reduce manufacturing costs.

[0034] To achieve the above objectives, the present invention provides the following technical solution:

[0035] Please see Figures 1 to 6 This embodiment provides a lifting module for a medical trolley, which is installed on the base 03 of the medical trolley to enable the lifting of the medical trolley. The module includes a lifting assembly and a pedal 01. The lifting assembly includes an outer profile 07 and an inner profile 14. The inner profile 14 is movably installed inside the outer profile 07, and a profile patch 15 is provided between the outer profile 07 and the inner profile 14. A gas spring 16 is installed inside the inner profile 14, and the top end of the gas spring 16 is fixedly connected to the end of the outer profile 07. The gas spring 16 provides the power for the lifting assembly to rise or fall. The pedal 01 is rotatably disposed on the lower side of the base 03 and is used to control the rising or falling motion of the gas spring 16 when stepped on.

[0036] In this embodiment, as Figure 1 and Figure 2As shown, the lifting assembly is vertically mounted on the base 03, and a rotatable pedal 01 is provided on the lower side of the base 03. One end of the pedal 01 is for the operator to step on, and the other end is located below the lifting assembly. In this embodiment, the bottom end of the gas spring 16 is provided with a contact point 1603 that can control its extension or retraction. At the same time, a top post 13 is provided at the end of the pedal 01 located at the bottom end of the lifting assembly. The top post 13 passes through the base 03 and contacts the bottom end of the gas spring 16. When the operator steps on the pedal 01, the other end of the pedal 01 will lift up, which will drive the top post 13 to move upward, thereby causing the gas spring 16 to extend or retract. In addition, a top post spring 12 for resetting the pedal 01 is also sleeved on the outer circumference of the top post 13.

[0037] In this embodiment, the lifting assembly mainly includes an outer profile 07 and an inner profile 14 that can move relative to each other. The bottom end of one of them is fixedly connected to the base 03, and the top end of the other is fixedly connected to the top end of the gas spring 16. In this way, when the gas spring 16 extends or shortens, the lifting assembly will rise or fall.

[0038] It is important to note that a profile patch 15 is provided between the inner profile 14 and the outer profile 07, and the gap between the profile patch 15 and the inner and outer profiles 07 is very small, resulting in a tight fit after assembly, almost like zero-fitting. This effectively prevents excessive wear between the inner profile 14 and the outer profile 07. Moreover, the profile patch 15 allows for smooth movement between the inner profile 14 and the outer profile 07 while preventing them from wobbling during relative movement. Finally, when the profile patch 15 is severely worn, only the profile patch 15 needs to be replaced instead of the entire lifting assembly, thus saving costs.

[0039] In this embodiment, the bottom end of the inner profile 14 is provided with a base connecting block fixing hole 1403, which is used to install the base connecting block 04. The base connecting block 04 can be directly installed into the base 03. For the sake of overall aesthetics, a film 05 is also provided on the upper side of the base connecting block 04. The middle part of the inner profile 14 is provided with an inner profile inner channel 1401, which is used to install the gas spring 16. The sides of the top end of the inner profile 14 are provided with inner profile patch fixing holes 1402, which are used to install profile patches 15. The sides of the bottom end of the inner profile 14 are provided with base connecting block 04 fixing holes, which are used to install the base connecting block 04 with screws.

[0040] like Figure 3 and Figure 5As shown, the inner profile 14 is provided with an inner profile inner channel 1401, an inner profile patch fixing hole 1402, and a base connecting block 04 fixing hole; the inner profile inner channel 1401 is a cavity that can accommodate the gas spring 16; the inner profile patch fixing hole 1402 is located above the inner profile 14, and the fixing hole is provided on all four outer sides of the inner profile 14, which can be tightly fitted with the profile patch 15 for fixing the profile patch 15; the base connecting block 04 fixing hole is located below the inner profile 14, and the fixing hole is provided on all four outer sides of the inner profile 14. After the inner profile 14 is inserted into the base connecting block 04, the hole is used to fix the base connecting block 04 to the inner profile 14.

[0041] Furthermore, the lifting assembly also includes a profile end cap 06. The outer profile 07 has an outer profile inner channel 0701 in the middle for accommodating the inner profile 14. The bottom end of the outer profile 07 has a profile end cap fixing hole 0705. The profile end cap 06 is sleeved on the bottom end of the outer profile 07 and is fixedly connected to the outer profile 07 by screws passing through the profile end cap fixing hole 0705.

[0042] In addition, a gas spring connecting block 17 is fixedly installed at the top of the gas spring 16, and the gas spring connecting block 17 is fixedly installed to the end of the outer profile 07.

[0043] Specifically, such as Figure 3 and Figure 6 The outer profile 07 is provided with an inner channel 0701, a gas spring connecting block fixing hole 0702, a storage basket fixing hole 0703, an outer profile patch fixing hole 0704, and a profile end cap fixing hole 0705. The inner channel 0701 is a square hole that can accommodate the inner profile 14 and the profile patch 15. The gas spring connecting block fixing hole 0702 is located at the top of the outer profile 07 and is used to fix the gas spring connecting block 17 and the gas spring 16. The storage basket fixing hole 0703 is located in the middle of the front end face of the outer profile 07 and is used to lock the storage basket 08 onto the outer profile 07. The profile end cap fixing holes 0705 are located on both sides below the outer profile 07 and are used to fix the profile end cap 06 onto the outer profile 07.

[0044] Understandably, the outer profile 07 is movably fitted onto the outer periphery of the inner profile 14, and a wear-resistant profile patch 15 is provided between the two. The bottom end of the inner profile 14 is installed in the base 03 through the base connecting block 04, and a gas spring 16 is installed in the inner profile 14. The bottom end of the gas spring 16 is connected to the base connecting block 04, and the top end of the gas spring 16 is connected to the top end of the outer profile through the gas spring connecting block 17. In this way, when the gas spring 16 extends, the top end of the gas spring 16 can drive the outer profile to rise. At the same time, the other components installed on the outer profile 07 can rise or fall with the outer profile 07.

[0045] Furthermore, the gas spring 16 includes a gas spring contact end 1601 and a gas spring contact end 1602. The gas spring contact end 1601 is provided with a telescopic contact 1603. The gas spring contact end 1601 is threadedly locked to the center of the base connecting block 04, and the contact 1603 extends out of the base connecting block 04 and abuts against the pedal 01. The gas spring contact end 1602 is threadedly locked to the center of the gas spring connecting block 17.

[0046] In this embodiment, the top end of the gas spring 16 is the gas spring contact end 1602, which is threaded and can be threadedly connected to the gas spring connecting block 17. The bottom end of the gas spring 16 is the gas spring contact end 1601, which is also threaded and locked to the center thread of the base connecting block 04. However, this end is provided with a contact point 1603. When an external force presses against the contact point 1603, the gas spring 16 will extend. When the gas spring 16 needs to be shortened, it is only necessary to apply a downward pressure to the top end of the gas spring 16 while pressing against the contact point 1603. In this embodiment, the contact point 1603 extends out of the base connecting block 04 and connects to the top post 13. When someone steps on the pedal 01, the other end of the pedal 01 will tilt up, causing the top post 13 to press against the contact point 1603, thereby controlling the lifting and lowering of the gas spring 16.

[0047] In this embodiment, the profile patch 15 includes a patch sliding plane 1502 and two patch positioning posts 1501 vertically disposed on the patch sliding plane 1502. The patch positioning posts 1501 are used to be installed into the inner profile patch fixing hole 1402 or the outer profile patch fixing hole 0704 to complete the installation of the profile patch 15.

[0048] Specifically, such as Figures 4 to 6 As shown, the profile patch 15 is provided with two patch positioning posts 1501 and a patch sliding plane 1502. The patch positioning posts 1501 correspond to the patch fixing holes of the inner and outer profiles 07 and can be directly pressed and fixed. This setting facilitates the installation of the lifting assembly. After the lifting assembly is assembled, the profile patch 15 is located between the inner and outer profiles 07. The patch sliding plane 1502 makes the inner and outer profiles fit tightly without shaking, while also allowing for smooth sliding.

[0049] Furthermore, a plurality of through holes are evenly provided on the patch sliding plane 1502, and patch chamfers 1503 are provided around the patch sliding plane 1502.

[0050] Understandably, when the profile patch 15 slides between the outer profile 07 and the inner profile 14, heat will be generated due to friction. The through holes provided on the patch sliding plane 1502 can accelerate the heat dissipation and thus extend the service life of the patch sliding plane 1502. In addition, since the inner and outer profiles fit tightly with the profile patch 15 during installation, the profile patch 15 is provided with a patch chamfer 1503 for easy installation.

[0051] Preferably, the cross-sections of the inner channel 0701 of the outer profile and the inner profile 14 are both square.

[0052] In this embodiment, the cross-section of the inner channel 0701 of the outer profile and the inner profile 14 is preferably square, but other shapes can be selected according to the actual situation. However, the inner channel 0701 of the outer profile and the inner profile 14 need to be able to cooperate so that the lifting assembly can operate normally.

[0053] Preferably, the outer profile 07 has a storage basket fixing hole 0703 in the middle of its outer side surface for installing the storage basket 08.

[0054] In this embodiment, a storage basket fixing hole 0703 is also provided at the middle position on the outer side of the outer profile 07, which is used to install the storage basket 08.

[0055] In this embodiment, the bottom side of the outer profile 07 is provided with an outer profile patch fixing hole 0704 for installing the profile patch 15.

[0056] Specifically, such as Figure 6 As shown, the profile patch 15 is respectively set on the outer side of the top of the inner profile 14 and the inner side of the bottom end face of the outer profile 07. Therefore, the outer profile patch fixing hole 0704 is set at the bottom of the outer profile 07. The four sides of the outer profile 07 are provided with the fixing hole, which can be tightly matched with the patch positioning post 1501 of the profile patch 15.

[0057] When the lifting assembly provided in this embodiment is assembled onto the medical trolley, the top column spring 12 and the top column 13 are first placed in the hole below the base 03, and the pedal 01 is fixed to the bottom of the base 03 with screws. The pedal 01 can pry the top column 13 to move up and down. The caster 02 is fixed to the bottom of the base 03. The base connecting block 04 in the lifting assembly is inserted into the square hole in the middle of the base 03 and locked with screws. The storage basket 08 is fixed to the front end of the lifting module and can be raised and lowered synchronously with the outer profile 07. The screen bracket 11 is fixed to the storage tray 09 with screws, the probe cup 10 is placed in the groove of the storage tray, and the storage tray 09 is fixed above the lifting module with screws.

[0058] When the pedal 01 of the assembled medical trolley is pressed down, it pries the top column 13 to move upward and contact the contact point 1603 of the gas spring 16, causing the gas spring 16 of the lifting module to extend and drive the outer profile 07 to rise. At the same time, the storage basket 08, the storage tray 09, the probe cup 10, and the screen bracket 11 rise synchronously. When no pressure is applied to the pedal 01, the top column 13 returns to its original position under the elastic force of the top column spring 12 and no longer contacts the contact point 1603 of the gas spring 16. The gas spring 16 remains in its current state, keeping the medical trolley at a suitable height. When pressure is applied to the pedal 01, the gas spring 16 is triggered to extend and retract. Pressing the storage tray 09 will cause the gas spring 16 to retract, lowering the trolley height. Once the suitable height is reached, no pressure is applied to the pedal 01, and the medical trolley remains stable at the appropriate height.

[0059] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0061] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
