DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Please refer to Figures 1-6 The utility model provides technical schemes as follows: A floor type showing stand, including base 2, showing frame 1 and top cover 8, showing frame 1 is fixedly connected on base 2, and both showing frame 1 and top cover 8 are fixedly connected with first clamping slot 7, the inside of base 2 is provided with installation slot, and the inside of installation slot is provided with lifting roller structure and limiting structure.

[0022] When using the showing stand, first, the display board is placed in the first clamping slot 7 inside the showing frame 1, then the top cover 8 is placed on the showing frame 1, and then the two first clamping slots 7 cooperate to position the display board, when the whole showing stand needs to be moved, the lifting roller structure and the limiting structure cooperate to drive the whole showing stand to move, after the movement is completed, the lifting roller structure is retracted, and the movement is completed.

[0023] Please refer to Figure 2 and Figure 3 The lifting roller structure comprises a sliding block 9 slidingly connected in the inside of the base 2, a connecting rod 4 fixedly connected on the sliding block 9, and two rollers 5 symmetrically and rotatably connected at the two ends of the connecting rod 4, the sliding block 9 cooperates with the limiting structure, and the lifting roller structure further comprises a plurality of slideways 6 fixedly connected in the inside of the installation slot and slidingly connected with the connecting rod 4.

[0024] Through the above structure, when the lifting of the lifting roller structure is specifically implemented, as shown in Figure 2 and Figure 3 By sliding the sliding block 9 in the inside of the base 2, the four rollers 5 and the connecting rod 4 can be moved up and down, and the plurality of slideways 6 can reduce the shaking of the connecting rod 4 during the movement, so that the whole showing stand is more stable.

[0025] As shown in Figure 2 and Figure 3 The limiting structure comprises a clamping block mechanism and a driving mechanism, the clamping block mechanism comprises two sliding grooves 11 symmetrically provided in the inside of the base 2, a sliding plate 12 slidingly connected in the inside of the sliding groove 11, and a second clamping slot 10 provided in the inside of the sliding block 9 and cooperating with the two sliding plates 12.

[0026] The sliding plate 12 slides in the sliding groove 11, as shown in Figure 3As shown, when the two slides 12 contact each other, they will prevent the slider 9 from sliding upward, thereby limiting the movement of the four rollers 5, and then the slider 9 will contact the bottom of the two slides 12 to provide support for the entire display stand. When the two slides 12 slide to both sides, the slider 9 can slide upward, so that the four rollers 5 are retracted into the inside of the base 2, and the two slides 12 slide toward the middle again and are stuck in the inside of the second slot 10, limiting the movement of the rollers 5, so that the display stand can be placed stably on the ground.

[0027] like Figure 4 and Figure 5 As shown, the driving structure includes a pedal 13 and two first slide bars 14 symmetrically fixedly connected to the bottom of the pedal 13. Two slots are provided inside the base 2. The two first slide bars 14 are both slidably connected to the inside of the slots, and a spring 15 is fixedly connected between the first slide bar 14 and the slots. A threaded groove 16 is provided on the first slide bar 14. The driving structure also includes two gear rings 19 rotatably connected to the base 2. The inner wall of the gear ring 19 is fixedly connected to the second slide bar 17, and the two second slide bars 17 are respectively slidably connected to the inside of the two threaded grooves 16. One side of the two slides 12 is fixedly connected to a rack 18 meshing with the gear ring 19, and a baffle 3 is fixedly connected between the inner walls of the mounting grooves.

[0028] Through the above structure, when the two slide plates 12 are moved, when the pedal 13 is stepped on, the two first slide bars 14 are pushed toward the inside of the slot in the base 2 and start to squeeze the spring 15. Figure 5 As shown, the gear ring 19 on the left will rotate counterclockwise, and the gear ring 19 on the right will rotate clockwise, driving the rack 18 to move through the gear ring 19, so that the two slides 12 move to both sides, allowing the slider 9 to slide, and then the display frame 1 and the base 2 are lifted upward, and the slider 9 moves downward relative to the base 2. After releasing the pedal 13, under the rebound action of the spring 15, the first slide bar 14 is pushed out from the inside of the slot, driving the gear ring 19 on the left to rotate clockwise, and the gear ring 19 on the right to rotate counterclockwise, the two slides 12 slide toward the middle, blocking the sliding of the slider 9. Similarly, when recovering, step on the pedal 13, the two slides 12 move to both sides, recovering the roller 5, and then release the pedal 13, the two opposing slides 12 move toward the middle, limiting the movement of the roller 5.

[0029] like Figure 6 As shown, triangular slots are symmetrically provided on both sides of the display frame 1 , and elastic blocks 20 are fixedly connected to both sides of the inner wall of the top cover 8 , and the elastic blocks 20 match the triangular slots.

[0030] When the top cover 8 is clamped to the display frame 1, the top cover 8 is first placed on the display frame 1, and the elastic clamping block 20 is squeezed and deformed until the elastic clamping block 20 moves into the triangular clamping groove, so that the top cover 8 is clamped to the display frame 1. When removing, the top cover 8 and the display frame 1 are separated by force. Under the action of pressure, the elastic clamping block 20 is deformed, so that the elastic clamping block 20 is withdrawn from the triangular clamping groove, so that the top cover 8 and the display frame 1 are separated.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
