[0037] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation of the present application.

[0038] The present application aims to provide a universal medical trolley base, which can reduce the size of the medical trolley while improving the universality of the medical trolley base.

[0039] To achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0040] Please refer to Figures 1 to 11 The present application provides a universal medical trolley base 1 for supporting a medical trolley, comprising: a base 1 and a base connecting block 2; the center of the base 1 is provided with a first mounting groove 11, and the lower side of the base 1 is detachably provided with a castor 12; the base connecting block 2 is detachably mounted in the first mounting groove 11, and the middle of the base connecting block 2 is provided with a second mounting groove 21, which is used for mounting a support assembly 3 of the medical trolley.

[0041] In the present embodiment, a plurality of detachable castors 12 are provided on the lower side of the base 1, which can facilitate the movement of the base 1, wherein the shape of the base 1 and the number and position of the castors 12 provided on the lower side can be adjusted according to actual conditions, as long as the base 1 can function smoothly.

[0042] The upper side of the center position of the base 1 is provided with a first mounting groove 11, and the lower side of the base 1 is provided with a castor 12, and the base connecting block 2 is detachably mounted in the first mounting groove 11, and the middle of the base connecting block 2 is provided with a second mounting groove 21, which is used for mounting a support assembly 3 of the medical trolley. Figure 6As shown, the first mounting slot 11 is used for inserting the support assembly 3; and in this embodiment, the support assembly 3 of the medical trolley is installed into the first mounting slot 11 of the base 1 through the base connecting block 2, so the inside of the first mounting slot 11 is used for installing the base connecting block 2, and in this embodiment, the shape and size of the first mounting slot 11 are matched with the shape and size of the base connecting block 2, and it is necessary to ensure that the base connecting block 2 can be installed into the first mounting slot 11.

[0043] And the inside of the base connecting block 2 is provided with a second mounting slot 21, and the second mounting slot 21 is used for installing the support assembly 3 of the medical trolley, so the shape and size of the second mounting slot 21 need to be adjusted according to actual needs, which is not limited herein.

[0044] In this way, the base 1 provided by the utility model is a general base 1, which can select the base connecting block 2 according to the support assembly 3 of different shapes, but does not need to replace the base 1 every time, increases the universality and adaptability of the base 1, and through the increase of the base connecting block 2, the switching mode of the medical trolley realizes modular assembly, which is convenient for disassembly, assembly and maintenance of the base 1.

[0045] In one embodiment, the lower side of the base 1 is provided with a rotatable pedal 4, the lifting contact 31 of the support assembly 3 extends from the bottom of the base connecting block 2, the bottom center of the first mounting slot 11 is provided with a guide through hole 13, the pedal 4 and the lifting contact 31 are provided with a jacking column 41, and the jacking column 41 is located in the guide through hole 13.

[0046] As shown in Figure 1 , Figure 3 and Figure 4 , when the support assembly 3 is a square tube shape, the support assembly 3 has a lifting function, and in this embodiment, the bottom of the support assembly 3 is provided with a lifting contact 31, which controls the lifting or lowering of the support assembly 3 when subjected to pressure, and in this embodiment, the action of the lifting contact 31 is controlled by the pedal 4 provided on the lower side of the base 1; specifically, the pedal 4 is rotatably installed on the lower side of the base 1, one end of the pedal 4 extends out of the base 1, which is convenient for medical staff to step on, and the other end is located below the first mounting slot 11, and at the same time, the middle part of the first mounting slot 11 is provided with a through guide through hole 13, as shown in Figure 6 and Figure 7 , the jacking column 41 is installed in the guide through hole 13, the bottom end of the jacking column 41 is in contact with the end of the pedal 4, and the other end is in contact with the lifting contact 31 extending from the base connecting block 2; in this way, when the medical staff steps on the pedal 4, the jacking column 41 will move upwards along the guide through hole 13, thereby pressing the lifting contact 31, and further controlling the lifting of the support assembly 3.

[0047] Furthermore, an annular protrusion is provided on the outer circumference of the top post 41, and a return spring 42 is installed between the protrusion and the lower side of the base 1. The return spring 42 is sleeved on the outer circumference of the top post 41. A limit groove 14 is provided on the lower side of the base 1. The cross-section of the limit groove 14 and the guide through hole 13 are both circular, and the two are coaxially arranged.

[0048] like Figure 3 As shown, in order to enable the top column 41 to automatically reset after each upward movement, this embodiment provides an annular protrusion on the circumference of the middle part of the top column 41. A reset spring 42 is installed between the annular protrusion and the lower side of the base 1. That is, the reset spring 42 is sleeved on the part of the top column 41 located on the upper side of the annular protrusion. In this way, when the top column 41 moves upward, it will compress the reset spring 42. When the external force on the pedal 4 is removed, the reset spring 42 will release the compressed elastic force, thereby forcing the top column 41 to reset downward.

[0049] In addition, to prevent the top column 41 from moving too far upward, resulting in an excessive length extending into the first mounting groove 11, which would affect the installation of the base 1 connecting seat, or cause excessive pressure on the lifting contact 31 and damage it, a limiting groove 14 that cooperates with the annular protrusion is provided on the lower side of the base 1 and at the lower end of the guide hole 13. The setting of the limiting groove 14 can effectively prevent the top column 41 from moving upward beyond the expected range.
