Treatment table capable of being opened in multiple directions
Technical Field
The invention relates to medical equipment, in particular to a treatment table opened in multiple directions.
Background
The treatment table is one of necessary spare articles in hospital treatment rooms, the position of the treatment table in the hospital is fixed at present, the treatment table is mostly cabinet type, the table top is used for adding medicine, the part below the table is mostly drawers and cabinets, and articles required by treatment are all placed at the fixed position of the treatment table.
When medical staff need take the articles from the drawer, the medical staff need to draw the drawer out of the drawer groove, and the drawn drawer enables the medical staff to be far away from the treatment table, so that the medical staff are inconvenient to place the articles taken out of the drawer on the treatment table top, and particularly when the medical staff need to take the articles on the inner side of the drawer.
When the treatment volume is big, often need many people to enclose in treatment platform limit and add the medicine, traditional pull formula drawer is extremely inconvenient many people and gets the thing simultaneously, often need dodge mutually, has increased medical staff's intensity of labour, has reduced medical staff's work efficiency.

Detailed Description
As shown in fig. 1 to 6, a multi-directional opening treatment table comprises a frame 10 with square columns and four drawers 20; four drawer grooves 100 in the shape of a square column groove are uniformly formed in the machine frame 10 and are distributed vertically; the four side walls of the drawer groove 100 are respectively formed with a drawing groove 1000 outwards; the drawer 20 is disposed in the drawer slot 100 and is extractable along any of the extraction slots 1000; the drawer 20 is provided with a drawing selection device; the drawing selection means is used to select a drawing direction of the drawer 20.
As shown in fig. 1 to 6, a cylindrical groove-shaped limiting groove 101 is formed in the middle of the bottom surface of the drawer groove 100; four drawing-out sliding grooves 102 which are uniformly distributed in the circumference and penetrate outwards are formed in the side wall of the limiting groove 101; the direction of drawing out the sliding slot 102 is vertical to the end surface of the corresponding side of the frame 10; the extraction selection means comprise a rotary limit lever 24; the rotary limiting rod 24 is rotatably arranged in the limiting groove 101, and the width of the rotary limiting rod 24 is equal to the groove width of the extraction sliding groove 102; a cylindrical limiting central column 22 is formed on the upper end surface of the rotary limiting rod 24; a driving groove 201 in a square groove shape is formed in the lower part of the drawer 20; the upper end of the limiting central column 22 passes through the driving groove 201 and is pivoted on the upper side wall and the lower side wall of the driving groove 201; a rotary driving gear 23 is formed on the part of the limiting central column 22, which is positioned in the driving groove 201; the upper parts of the front and rear side walls of the driving groove 201 are respectively formed with a rectangular upper sliding driving groove 202 which penetrates outwards, and the lower parts of the left and right side walls are respectively formed with a rectangular lower sliding driving groove 204 which penetrates outwards; an upper sliding driving rod 251 is arranged in the upper sliding driving groove 202 in a left-right sliding mode; an upper driving rack 25 is vertically formed at one end of the pair of upper sliding driving rods 251 adjacent to each other; a pair of upper driving racks 25 are positioned at both front and rear sides of the rotation driving gear 23 and the pair of upper driving racks 25 are respectively engaged with the rotation driving gear 23; a lower sliding driving rod 261 is arranged in the lower sliding driving groove 204 in a front-back sliding manner; one ends of the pair of lower sliding driving rods 261 close to each other are respectively and vertically formed with a lower driving rack 26; a pair of lower driving racks 26 are positioned at left and right sides of the rotation driving gear 23 and the pair of lower driving racks 26 are respectively engaged with the rotation driving gear 23; a pair of upper drive racks 25 are positioned above a pair of lower drive racks 26.
As shown in fig. 1, 2, 4 and 6, the upper and lower side walls of the lower slide driving groove 204 are respectively formed with rectangular front and rear guide grooves 205; front and rear guide blocks fitted to the front and rear guide grooves 205 are formed on upper and lower end surfaces of the lower slide driving lever 261, respectively.
As shown in fig. 1, 2, 4 and 6, the upper and lower side walls of the upper slide driving groove 202 are respectively formed with rectangular left and right guide grooves; left and right guide blocks matched with the left and right guide grooves are respectively formed on the upper and lower end surfaces of the upper sliding drive rod 251.
As shown in fig. 4 and 5, a drawer limiting rod 241 is slidably disposed on the rotation limiting rod 24; both ends of the drawer stopper 241 exceed the corresponding end surfaces of the rotation stopper 24.
As shown in fig. 5, both ends of the rotation restricting lever 24 are formed as arc surfaces; the two ends of the rotary limiting rod 24 are coaxial with the limiting groove 101 and have the same diameter.
As shown in fig. 1, 2 and 4, a handle seating groove 200 having a semi-cylindrical groove shape is formed at the upper middle portion of the four end surfaces of the drawer 20; an opening and closing handle 21 is arranged in the handle placing groove 200; when the opening-closing handle 21 is in the initial state, the end surface of the opening-closing handle 21 is flush with the end surface of the corresponding side of the drawer 20.
A plurality of storage grooves are uniformly distributed in the drawer 20.
The working principle of the multi-direction opening treatment table is as follows:
initial state: the drawer 20 is positioned in the drawer slot 100, the rotation limiting rod 24 is arranged to incline 45 degrees from left to right, the lower sliding driving rod 261 is positioned in the middle of the lower sliding driving slot 204, and the upper sliding driving rod 251 is positioned in the middle of the upper sliding driving slot 202;
when the drawer 20 needs to move forward, the upper sliding driving rod 251 on the front end surface of the drawer 20 moves rightwards, so that the limiting central column 22 is driven by the rotating driving gear 23 to rotate 90 degrees anticlockwise, the rotating limiting rod 24 is arranged in the front-back direction and is opposite to a pair of extraction sliding grooves 102 in the front-back direction, and the drawer 20 can move forward; similarly, the drawer 20 needs to be pulled out in any direction, and the rotation limiting rod 24 can be driven to change into a horizontal left-right direction or a horizontal front-back direction only by moving the upper sliding driving rod 251 or the lower sliding driving rod 26 on the corresponding end surface of the drawer 20; can satisfy a plurality of medical staff and get the thing from the drawer of difference simultaneously like this, not only make things convenient for medical staff, improve medical staff's work efficiency simultaneously.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
