The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1, an embodiment of the present invention provides a medical trolley, which includes a lifting column fixing mechanism, a display 110, an endoscope bracket 111, an operation table 121, a trolley chassis 122, and a chassis module 123, wherein the lifting column fixing mechanism includes a main vertical tube 12, a lifting column 11, and a lifting column fixing assembly 13, the display 110 and the endoscope bracket 111 are mounted on the lifting column 11, and the operation table 121, the trolley chassis 122, and the chassis module 123 are mounted on the main vertical tube 12; wherein the lifting column 11 can move axially relative to the main riser 12 to adjust the height of the lifting column 11; the lifting column fixing assembly 13 is used for fixedly connecting the lifting column with the main vertical pipe after the lifting column reaches a proper height.

In some embodiments of the present invention, the lifting column 11 is telescopically sleeved in the main vertical pipe 12, the upper side of the main vertical pipe 12 is provided with at least one radially extending mounting hole 121,122, and an inner thread is provided on an inner circumferential surface of the

mounting hole

121, 122;

referring to fig. 2-4, the lifting pillar fixing assembly 13 includes at least one fixing rod 15 and a decorative cover 16; the fixing rod 13 extends radially, the fixing rod 15 at least has a head end 150, a threaded section 152 (threads are not shown in fig. 2) and a stopping end 151 along the length extension direction thereof, the head end 150 stops at the outer side of the main

riser mounting holes

121 and 122, the threaded section 152 can be in threaded fit with the

mounting holes

121 and 122, and at this time, the stopping end 151 of the fixing rod can stop against the lifting column 11 to limit the release of the lifting column 11. In this embodiment, the tail end of the fixing rod is pressed against the outer peripheral wall of the lifting column to position the lifting column.

The decorative cover 16 is detachably sleeved on the upper side of the main vertical pipe 12 to shield the fixing rod 15, the decorative cover 16 further forms a pivot hole 161 for the lifting upright 11 to pass through, and the decorative cover 16 can slide along the lifting upright 11. Thus, when the adjustment is needed, the decoration cover 16 is removed, and when the fixing rod 15 is screwed, the decoration cover 16 is sleeved to shield the lifting upright post fixing component 13 so as to ensure that the overall appearance of the medical trolley is attractive, and the parts of the fixing rod are prevented from being exposed.

In some embodiments, the main riser 12 and the lifting column 11 are both made of hardware, and the fixing rod is made of metal, such as a screw. So, when the direct radial movement of screw and lift stand stopped, can take place the friction mar. Based on this, be equipped with protective sheath 17 between main riser 12 that this embodiment provided and lift stand 11, the protective sheath adopts deformable material, end 151 can support and press this protective sheath 17 to warp to finally end the cooperation of supporting through this protective sheath 17 and lift stand 11 that warp, so, avoid ending and end and lift stand direct frictional contact take place the mar easily and join in marriage technical problem such as unstability. In some embodiments, when the height of the lifting column needs to be adjusted, a user can hold the upper end of the protection sleeve to prevent the protection sleeve from falling off the main vertical pipe, and after the lifting column is adjusted to a proper height, the fixing rod is screwed to fix the main vertical pipe, the protection sleeve and the lifting column to each other. In some preferred embodiments, the protective sleeve 17 has a flared edge 171 at the top end, and the flared edge 171 stops at the top side of the main riser to prevent the protective sleeve from falling out, and is also convenient for the user to hold in his/her hand, so that the protective sleeve 17 is prevented from being displaced from the main riser 12 when the height of the lifting column 11 is adjusted.

In the present embodiment, please refer to fig. 4 and 5, the trim cover 16 is in limit fit with the main vertical pipe 11 to prevent the trim cover from shifting. The inboard of dress trim cover set up at least one buckle 161, the outside of main riser is provided with at least one draw-in groove 125, this draw-in groove 125 and the spacing cooperation of buckle 161, so, when the dress trim cover is established in the outside of main riser, the inboard buckle 161 of dress trim cover inserts in this draw-in groove 16 with the location dress trim cover, avoids the dress trim cover aversion to throw off.

In some embodiments, referring to fig. 6, the fixing rod 15 forms a threaded section 152 and a polish rod section 153 from the head end to the stop end, the polish rod section 153 has a smaller radial dimension than the threaded section 152 so as to facilitate quick penetration through the installation hole, for example, if the outer dimension of the main riser is different from that of the lifting column, a screw may be selected from the form shown in fig. 6, wherein the polish rod section 153 is a polish rod portion having a diameter of the polish rod portion

Smaller than the size of the threaded portion

So, the dead lever polished rod part is smooth and easy to pass through the mounting hole fast, when having ensured that the length of dead lever can satisfy and reach the lift stand, has avoided the work of screwing that the screw thread section of overlength brought, is showing and is reducing installation work volume.

In some embodiments, as shown in the drawings, the main vertical rod is provided with four mounting holes along its circumferential side, two-by-two sets of symmetrical arrangement are provided, accordingly, four fixing rods such as screws need to be provided, the distances from the

mounting holes

121 and 122 to the top of the vertical rod are D1 and D2 respectively, D1 ≠ D2, thus, 4 fastening screws (fixing rods) fix the points of the lifting vertical rod, the fastening screws fix the lifting vertical rod in a staggered manner, and two-by-two sets of fastening screws are arranged in a highly staggered manner and are not on the same plane, which is beneficial to stably fixing the lifting vertical rod.
