DETAILED DESCRIPTION

[0019] like Figures 1-4 As shown, the utility model provides a technical solution: a portable promotional stand, comprising a column 1, an auxiliary rod 2 hinged to the outer wall of the column 1, a folding mechanism 3 provided on the outer wall of the column 1, and a supporting mechanism 4 provided on the outer wall of the column 1.

[0020] The folding mechanism 3 includes: a slide 301, a slider 302, a hinge rod 303, a long slot 304, a clamping rod 305, a spring 306, a pressure rod 307, a rectangular slot 308, a handle 309, a return spring 310 and a push rod 311. The slide 301 is provided inside the column 1, the slider 302 slides on the inner wall of the slide 301, the outer wall of the slider 302 is hinged with a hinge rod 303, one end of the hinge rod 303 is hinged to the outer wall of the slider 302, and the hinge rod 311 is provided on the outer wall of the slider 302. The other end of the connecting rod 303 is hinged to the outer wall of the column 1. A long slot 304 is provided inside the column 1. A clamping rod 305 is slidably installed on the inner wall of the long slot 304. A spring 306 is fixedly installed on the inner wall of the long slot 304. One end of the spring 306 is fixedly installed on the inner wall of the long slot 304, and the other end of the spring 306 is fixedly installed on the outer wall of the clamping rod 305. A pressure rod 307 is fixedly installed on the inner wall of the clamping rod 305. A rectangular slot 308 is provided on the inner wall of the auxiliary rod 2. When the handle 309 is in the unlocking state, the locking lever 302 is locked and the locking lever 303 is unlocked, and the locking lever 302 is unlocked, so that the user can unlock the handle 309.

[0021] The support mechanism 4 includes: an articulated block 401, a long rod 402, a short rod 403, a rectangular rod 404, a connecting rod 405 and a support plate 406. The articulated block 401 is fixedly mounted on the outer wall of the column 1. The outer wall of the articulated block 401 is hinged with the long rod 402. There are two groups of articulated blocks 401, which are mirror-imaged with the center line of the support plate 406 in the vertical direction as the axis of symmetry. The outer walls of the two groups of articulated blocks 401 are both hinged with the long rod 402. The outer wall of the long rod 402 is hinged with the short rod 403. The outer wall of the long rod 402 is hinged with the rectangular rod 404. The rectangular rod 404 is provided with There are two groups, and a connecting rod 405 is hinged between the two groups of rectangular rods 404. A support plate 406 is fixed to the bottom of the connecting rod 405. By bending the auxiliary rod 2, the long rod 402 and the short rod 403 are brought closer to each other and the auxiliary rod 2 is moved closer to the column 1. At this time, the column 1 is bent so that the slider 302 slides on the inner wall of the slide groove 301 and the hinged rod 303 pulls the columns 1 to retract each other. At this time, the middle part of the rectangular rod 404 hinged to the outer wall of the long rod 402 will move inward due to the hinged relationship and pull up the connecting rod 405 and the support plate 406 to move upward, thereby releasing the support on the ground.

[0022] When the columns 1 are retracted, the auxiliary rod 2 will squeeze the support rod 311 so that the handle 309 slides outward on the inner wall of the rectangular groove 308 and leaks out, making it convenient for the staff to take it and carry it.

[0023] When it is needed to use, the pressure rod 307 is pushed downward to make the card rod 305 slide downward on the inner wall of the long groove 304 and release the limit of the column 1. By pulling the column 1, the slider 302 slides downward on the inner wall of the slide groove 301 and the hinge rod 303 pushes the columns 1 away from each other. At this time, the auxiliary rod 2 is bent to make the long rod 402 and the short rod 403 separate from each other and move away from the column 1. At this time, the rectangular rod 404 on the outer wall of the long rod 402 will expand outward and make the connecting rod 405 move downward, driving the support plate 406 to contact the ground for support, making the overall propaganda stand more stable. As the columns 1 move away from each other, the auxiliary rod 2 releases the squeezing of the supporting rod 311, and the return spring 310 pulls the handle 309 to slide inward on the inner wall of the rectangular groove 308 to complete the retraction, preventing the handle 309 from being in the extended state, which is more troublesome and easily causes the handle 309 to get dirty.

[0024] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
