[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-8 As shown, an innovative entrepreneurial project display device includes a box body 1, a roller 2 is rotatably installed on the left side of the box body 1, a pull rod 3 is installed on the right side of the box body 1, and a box cover 4 is hinged on the upper side of the box body 1, characterized in that: a display mechanism is installed inside the box body 1;

[0025] The display mechanism includes a vertically installed telescopic rod assembly, the number of the telescopic rod assemblies is two groups and they are symmetrically distributed left and right, a cross bar 5 is installed on the upper side of the telescopic rod assembly, a foldable display screen assembly is hinged on the lower side of the cross bar 5, and two front-to-back symmetrically distributed slide rails 6 are installed at the bottom of the box body 1, and the bottom of the display screen assembly is connected to the slide rail 6 for forward and backward sliding.

[0026] When the utility model is not in use, the display screen assembly is in a folded state, the telescopic rod assembly is in a retracted state and stored inside the box body 1, and the box cover 4 is in a closed state; when the display mechanism needs to be used, the box cover 4 is opened, and the cross bar 5 is pulled up to make the telescopic rod assembly in an extended state, and the display screen assembly can be unfolded.

[0027] The display screen assembly and the telescopic rod assembly enable the display device to display complex items while being conveniently stored when not in use. The pull rod 3 and the roller 2 enable the display device to be conveniently moved and carried when in use. The cooperation between the box cover 4 and the box body 1 enables the display mechanism to be isolated from the outside of the box body 1 when stored, thereby preventing it from being bumped and contaminated by dust, thereby improving ease of use and extending service life.

[0028] The telescopic rod assembly includes a plurality of sleeves 7, which are sleeved in layers, and adjacent sleeves 7 are connected by sliding up and down. The upper side walls of the other sleeves 7 except the sleeve 7 on the upper side are provided with a first circular hole 8, and the lower side walls of the other sleeves 7 except the sleeve 7 on the lower side are provided with a second circular hole 9 matching the first circular hole 8. A first bayonet 10 is installed on the bottom of the sleeve 7 on the upper side for sliding left and right, and a first spring 11 is installed between the first bayonet 10 and the inner wall of the corresponding sleeve 7. The bottom of the other sleeves 7 are all slidably installed with a second bayonet 12, the first bayonet 10 and the second bayonet 12 are matched with the first circular hole 8 and the second circular hole 9, the right side of the second bayonet 12 is connected with a slider 13 that slides left and right, an oblique groove 14 is provided on the upper side of the slider 13, a second spring 15 is installed between the right side of the slider 13 and the corresponding inner wall of the sleeve 7, the bottom of the other sleeves 7 except the lowermost sleeve 7 are installed with a triangular top block 16 that matches the oblique groove 14, and a control component for controlling the first bayonet 10 is installed on the lower side of the cross bar 5.

[0029] When the telescopic rod assembly is extended, the cross bar 5 lifts the uppermost sleeve 7 upwards. When the first bayonet 10 reaches the adjacent first circular hole 8, under the action of the first spring 11, the first bayonet 10 passes through the second circular hole 9 and is inserted into the first circular hole 8. At this time, the cross bar 5 drives the two sections of the sleeve 7 to move upwards. When the second bayonet 12 of the second section of the sleeve 7 passes through the first circular hole 8 of the third section of the sleeve 7, under the action of the second spring 15, the second bayonet 12 passes through the corresponding second circular hole 9 and is inserted into the first circular hole 8. At this time, the third section of the sleeve 7 follows the upward movement, and the cycle continues.

[0030] When the telescopic rod assembly needs to be stored, the control assembly causes the first bayonet 10 to retract inwardly, and at this time, the uppermost sleeve 7 can fall downwardly. When the triangular top block 16 on the lower side of the first sleeve 7 contacts the inclined groove 14 on the inner side of the second sleeve 7, the inclined groove 14 is squeezed by the triangular top block 16 and drives the slider 13 to slide, causing the second bayonet 12 to retract inwardly, so that the second sleeve 7 can fall; when the triangular top block 16 on the lower side of the second sleeve 7 contacts the inclined groove 14 located on the inner side of the third sleeve 7, the inclined groove 14 is squeezed by the triangular top block 16 and drives the slider 13 to slide, causing the third bayonet 12 to retract inwardly, so that the third sleeve 7 can fall, and the above operation is repeated.

[0031] The cooperation of the first bayonet 10, the second bayonet 12, the inclined slot 14 and the triangular top block 16 ensures that the telescopic rod assembly can be normally extended and fixed, while at the same time making the adjustment range of the telescopic rod assembly larger and being able to stop at different heights, and at the same time making the telescopic rod assembly have a stronger load-bearing capacity, thereby improving the reliability of the display device.

[0032] The control assembly includes a handle 17 hinged to the cross bar 5, a pull block 18 which is rotatably installed on the inner side of the uppermost sleeve 7 and is transmission-connected to the handle 17, a ring 20 fixed to the inner wall of the sleeve 7 is installed on the side of the first bayonet 10 away from the second circular hole 9, a pull rope 19 is connected to the side of the first bayonet 10 close to the first spring 11, the middle part of the pull rope 19 passes through the ring 20 and the other side is transmission-connected to the pull block 18.

[0033] When the telescopic rod assembly needs to be stored, the staff squeezes the handle 17 upwards, and the handle 17 rotates to drive the pull block 18 to rotate, so that the pull rope 19 pulls the first latch 10 inward to make it shrink inward, and the sleeve 7 can be stored downward; the cooperation between the pull rope 19 and the handle 17 makes the control assembly simple in structure, simple in operation and highly reliable, while reducing its manufacturing cost.

[0034] The display screen assembly includes a plurality of screens 21 , and a connecting piece 22 is commonly connected between two adjacent screens 21 . The plurality of screens 21 are connected end to end via the connecting piece 22 .
