DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7 , the utility model provides a technical solution: a steel-wood experimental table with an extension function, comprising a table 1;

[0029] The top surface of the table 1 is provided with a side expansion assembly 2, which includes a partition plate 201 symmetrically fixed to the top surface of the table 1, a column 202 is fixedly connected to the middle of the top surface of the table 1, an outer ring sleeve 203 is fixedly connected to the top of the column 202, an elliptical disk 204 is rotatably connected to the top of the column 202, and the elliptical disk 204 is rotatably connected to the bottom of the outer ring sleeve 203;

[0030] Among them, telescopic rods 206 are symmetrically fixedly installed on the top surfaces of both sides of the elliptical plate 204, and the top of the telescopic rods 206 is fixedly connected to the steel-wood table top 207. Push-pull rods 210 are rotatably connected to both sides of the elliptical plate 204, and the other end of the push-pull rods 210 is rotatably connected to the side display panel 211.

[0031] The inner side of the outer ring sleeve 203 is fixedly connected to the inner ring ring 205, and V-shaped grooves 208 are provided on the outer ring sleeve 203 and the inner ring ring 205. The top surfaces of the inner ring ring 205 and the outer ring sleeve 203 are both fitted with a support plate 209. The push-pull rod 210 is a bending rod. Finger grooves are provided on the sides of the steel-wood table top 207. The elliptical disk 204 is initially set at an angle; the descending distance of the support plate 209 sliding into the V-shaped groove 208 is the same as the descending distance of the steel-wood table top 207, so that the steel-wood table top 207 and the side display panel 211 are located in the same horizontal plane, and the finger grooves can assist the person to rotate the steel-wood table top 207 by hand. At the beginning of the elliptical disk 204, the straight lines at both ends of the elliptical disk 204 are not parallel to the partition plate 201.

[0032] The two V-grooves 208 and the support plate 209 are distributed at 180 degrees, and the top of the support plate 209 is fixedly connected to the bottom surface of the steel-wood table top 207; after the support plate 209 is displaced 180 degrees, it just slides completely into the V-groove 208, and because the steel-wood table top 207 has a large dead weight, the support plate 209 has a large friction with the outer ring sleeve 203 and the inner ring ring 205 under normal conditions, causing the steel-wood table top 207 to be unable to rotate sensitively.

[0033] The bottom of one side of the side display plate 211 close to the outer ring sleeve 203 is fixedly connected with a connecting plate 212, and the bottom end of the connecting plate 212 is fixedly connected with a sliding rod 213. The two sliding rods 213 are slidably connected to each other, and the sliding rod 213 is slidably connected to the inner side of the partition plate 201; the heights of the left and right connecting plates 212 are different, so that the two sliding rods 213 on different sides can slide against each other, and the sliding of the sliding rod 213 and the partition plate 201 can also support the side display plate 211.

[0034] The top surface of the steel-wood desktop 207 is provided with a folding component 3, which includes a flip table 301 symmetrically rotatably connected to the steel-wood desktop 207, and the flip table 301 is connected to the steel-wood desktop 207 through a plurality of hinges; the hinges enable the flip table 301 to be directly flipped horizontally while ensuring that the top surface of the flip table 301 is level with the surface of the steel-wood desktop 207.

[0035] A plurality of circular grooves 302 are provided at the connection gap between the flip table top 301 and the steel-wood table top 207. The circular grooves 302 include a first semicircular groove 303 opened on the flip table top 301, and the circular grooves 302 also include a second semicircular groove 304 opened on the steel-wood table top 207. Two pairs of gear protrusions 307 are symmetrically installed inside the circular grooves 302; the two pairs of gear protrusions 307 are distributed at 90 degrees, and each pair of gear protrusions 307 are also 90 degrees apart, so that the knob 306 can only rotate 90 degrees each time, and the gear protrusions 307 are fixedly connected to the inner wall of the circular groove 302.

[0036] The center of the second semicircular groove 304 is located on the steel-wood table top 207. An elliptical limiting plate 305 is rotatably connected to the center of the second semicircular groove 304. A knob 306 is fixedly connected to the top of the elliptical limiting plate 305. The height of the knob 306 is lower than the horizontal plane of the steel-wood table top 207. The elliptical limiting plate 305 overlaps with the shifting protrusion 307. Under normal circumstances, the elliptical limiting plate 305 is entirely located in the second semicircular groove 304.

[0037] Working principle: Before using this kind of steel-wood test bench with extension function, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 7 As shown, when the left side needs to be unfolded, the steel-wood tabletop 207 is pushed to rotate as a whole, so that the telescopic rod 206 drives the elliptical plate 204 to rotate, and then the push-pull rod 210 pushes the side display panel 211 to move horizontally along with the movement of the elliptical plate 204. When the steel-wood tabletop 207 rotates nearly 180 degrees, the side display panel 211 is directly unfolded and will be slightly pulled closer due to the rotation of the elliptical plate 204.

[0038] During the rotation of the steel-wood tabletop 207, the support plate 209 slides along the top surface of the inner ring 205 and the outer ring sleeve 203, and when rotating 180 degrees, the support plate 209 slides into the V-shaped groove 208, so that the height of the steel-wood tabletop 207 is reduced, and finally the side display panels 211 fit the steel-wood tabletop 207 from both sides so that they are located in the same plane; finally, the entire tabletop of the steel-wood laboratory bench can be quickly and conveniently unfolded, and the device has a simple structure and is easy to operate, which reduces the equipment cost and the difficulty of operation, and is convenient for promotion;

[0039] When the table surface needs to be expanded frontward and rearward, the flip table top 301 is directly flipped over to further expand the table top, and the knob 306 is rotated to make the elliptical limiting plate 305 fit the shifting protrusion 307, so that the elliptical limiting plate 305 spans the first semicircular groove 303 and the second semicircular groove 304, so that the flip table top 301 remains in the expanded state, thereby preventing the flip table top 301 from being flipped upward due to an accidental touch.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
