Disclosure of Invention
The utility model aims to overcome the problems of the adjustable tray on the conventional medical trolley and provides a self-locking adjustable tray mechanism for the medical trolley.
In order to realize the purpose of the utility model, the following technical scheme is adopted: the self-locking adjustable tray mechanism for the medical trolley comprises a stand column, wherein sliding grooves in the vertical direction are formed in the left side and the right side of the stand column, sliding blocks are arranged in the sliding grooves in a matched mode, the tray is fixedly connected with the sliding blocks through a support, the width of each sliding groove is larger than that of each sliding block, upward thorns are processed on two side walls of each sliding groove, downward thorns are processed on the side face, close to the tray, of each sliding block, and lower corners, far away from the side face of the tray, of each sliding block are edges and corners. Further, the method comprises the following steps of; the included angle between the tray and the sliding block is an acute angle.
Further, the method comprises the following steps of; the sliding block is provided with a screw hole, and a jackscrew is screwed in the screw hole.
Further, the method comprises the following steps of; the angle of the lower angle of the side surface of the sliding block, which is far away from the tray, is less than or equal to 90 degrees.
Further, the method comprises the following steps of; the downward thorns on the side surface of the sliding block close to the tray are distributed on the upper part of the side surface.
The utility model has the positive and beneficial technical effects that: the tray mechanism is simple in structure, simple and quick to adjust, reliable to lock, free of jacking failure and sudden and large-amplitude sliding, and capable of effectively guaranteeing safety and improving efficiency when applied to a medical trolley.

Detailed Description
In order to more fully explain the implementation of the present invention, examples of the implementation of the present invention are provided. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.
The utility model is explained in further detail in connection with the accompanying drawings, in which: 1: a column; 2: a chute; 3: a slider; 4: upward thorns; 5: downward thorns; 6: a support; 7: a tray; 8: and (5) jacking the screw.
As shown in the attached drawings, the self-locking adjustable tray mechanism for the medical trolley comprises a stand column 1, wherein the left side and the right side of the stand column are provided with a sliding groove 2 in the vertical direction, in the application, the sliding groove is a T-shaped groove, a sliding block 3 is arranged in the sliding groove in a matched mode, a tray 7 is fixedly connected with the sliding block through a support 6, an included angle between the tray and the sliding block is an acute angle, and in the graph 3, an angle B is an included angle between the tray and the sliding block.
The width of the sliding chute is larger than that of the sliding block, the width refers to the size in the left-right direction in fig. 1 and 2, upward thorns 4 are processed on two side walls of the sliding chute, downward thorns 5 are processed on the side surface of the sliding block close to the tray, the downward thorns on the side surface of the sliding block close to the tray are distributed on the upper part of the side surface, the lower corner of the side surface of the sliding block far away from the tray is an edge angle, the edge angle refers to that the lower corner of the side surface of the sliding block far away from the tray is not an arc-shaped corner in smooth transition, so that the corner can be supported by the upward thorns under the condition that the sliding block inclines, the angle of the lower corner of the side surface of the sliding block far away from the tray is smaller than or equal to 90 degrees, and in fig. 3, the angle a is the lower corner of the side surface of the sliding block far away from the tray.
More optimally, a screw hole is formed in the sliding block, and a jackscrew is screwed in the screw hole.
The principle of the mechanism is as follows: when the tray is put down, the sliding block can rotate clockwise under the action of gravity, the upper right corner (figures 1 and 2) of the sliding block can be positioned by matching the downward thorns with the downward thorns on the side wall of the sliding groove, and when the positioning is carried out, the distance of the thorns and the size of the sliding block are reasonably designed, so that the left corner can be supported by the upward thorns at the same time, the positioning is more reliable, the figure 2 is a schematic diagram of a locking position, and when the adjustment is needed, the tray sliding block is supported to rotate anticlockwise so that the upward thorns and the downward thorns do not interfere with each other (namely the state shown in figure 1), so that the height of the sliding block can be freely adjusted along the direction under the mountain.
Jackscrew in this mechanism is a mode of optimizing, the effect of jackscrew prevents that the tray can't provide enough big moment in the empty dish, the tray can rock like this when removing, need not jackscrew tight under the condition of tray if the heavy object is being pressed, adopt jackscrew tight in top to prevent that the tray from rocking under the very light state of tray weight, the jackscrew tight in top does not need too big when this usage, jackscrew in this application and traditional tray mechanism in adopt the effect difference of jackscrew locking height.
After the embodiments of the present invention have been described in detail, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the utility model, and it is intended that all simple modifications, equivalent changes and modifications made to the above embodiments based on the technical spirit of the present invention shall fall within the technical scope of the present invention, and the present invention shall not be limited to the embodiments illustrated in the description.
