DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a height-adjustable test workbench includes a work surface 1, a lifting bracket 2 is fixedly installed at the lower end of the work surface 1, the lifting bracket 2 is composed of a rectangular frame 15 and a movable connecting rod 5, there are four movable connecting rods 5 and they are symmetrically fixedly installed at the lower end of the rectangular frame 15, four upper guide plates 6 are symmetrically fixedly installed at the lower end of the rectangular frame 15 and between the four movable connecting rods 5, and the rectangular frame 15 on the lifting bracket 2 is fixedly installed at the lower end of the work surface 1.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the four movable connecting rods 5 are movably sleeved with two bottom brackets 3, and the bottom bracket 3 is composed of a cross brace 7, a support sleeve 8 and a lifting rod 9. There are two support sleeves 8 and they are symmetrically fixedly installed at the two ends of the cross brace 7. The lifting rod 9 is fixedly installed at the upper end of the cross brace 7. Two lower guide plates 10 are symmetrically fixedly installed on the upper end of the cross brace 7 and on both sides of the lifting rod 9. The support sleeve 8 on the bottom bracket 3 is movably sleeved on the movable connecting rod 5. A driving structure 4 is fixedly installed on the upper end of the lifting rod 9. The driving structure 4 is composed of a double-rod hydraulic cylinder 11, a connecting rod 12, a mounting bracket 13 and a rolling wheel 14. There are two connecting rods 12 and they are all fixedly installed on the telescopic rod of the double-rod hydraulic cylinder 11. There are four mounting brackets 13 And they are fixedly mounted on the upper and lower ends of the two connecting rods 12 respectively, there are four rolling wheels 14 which are rotatably mounted on four mounting brackets 13 respectively, the double-rod hydraulic cylinder 11 on the driving structure 4 is fixedly mounted on the upper end of the telescopic rod of the lifting rod 9, the upper rolling wheel 14 is in contact with the upper guide plate 6, and the lower rolling wheel 14 is in contact with the lower guide plate 10. By arranging the lifting bracket 2, the bottom bracket 3, the driving structure 4, the upper guide plate 6, and the lower guide plate 10, and fixing the work table 1 on the lifting bracket 2 at the same time, the height of the work table 1 can be adjusted according to the needs of the test personnel and the test, so that the practicality of the test workbench can be better, which is more conducive to experimental operation.

[0021] It should be noted that the utility model is a height-adjustable test workbench.
