[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a background board bracket comprises a display frame 1 and a display frame 2, a steel cable is arranged at the bottom of the display frame 1, a through hole is provided at the bottom of the display frame 2 for the steel cable to pass through, and a through slot 2 is provided at the top along the vertical direction for the steel cable to pass through, a through slot 1 is provided at the top of the display frame 1 along the vertical direction for the steel cable to pass through, a winding mechanism connected to one end of the steel cable is fixed on one side of the display frame 1, one end of the steel cable is fixed to the bottom of the display frame 1, the other end passes through the through hole and passes through the through slot 2 from the outside to the inside from the outside of the display frame 2, and then passes through the through slot 1 at any time, and finally is connected to the winding mechanism on the outside of the display frame 1, a card slot for the background board to be inserted is provided on the opposite sides of the display frame 1 and the display frame 2, a support platform for supporting the background board is fixed at the bottom of the card slot, and a display cavity for loading the background board is formed between the steel cable, the display frame 1 and the display frame 2.

[0007] By adopting the above technical solution, when it is necessary to place the background board, the staff first inserts the background board into the slots of the display rack 1 and the display rack 2, and places the background board on the support table. Then the staff can reel in the steel cable through the reeling mechanism. The steel cable wrapped around the outside of the background board drives the display rack 1 and the display rack 2 to approach each other and fit closely to the background board during the reeling process, and at the same time makes the steel cable press the background board downward, so that the background board is completely fixed in the display cavity. When placing background boards of different sizes, the distance between the display rack 1 and the display rack 2 can be freely adjusted according to the change of the size of the background board, and the steel cable can also move freely in the through slot 1 and the through slot 2 according to the change of the size of the background board, so as to change the size of the display cavity, so that the background board bracket can be used for displaying background boards of different sizes, and has high adaptability.

[0008] The utility model is further configured as follows: the winding mechanism includes two baffles fixed to the outside of the display rack, a rotating shaft is rotatably connected between the two baffles, a capstan is fixed on the rotating shaft, one end of the rotating shaft extends out of the baffle and is fixed with a handle, a limit pin is slidably connected to the handle, and a plurality of limit holes for inserting the limit pins are opened on the display rack.

[0009] By adopting the above technical solution, when the winding mechanism needs to wind up the steel cable, the staff can turn the handle, the rotation of the handle drives the rotating shaft to rotate, the rotation of the rotating shaft drives the winch to rotate, and the rotation of the winch causes the steel cable fixed on the winch to be wound on the winch, thereby achieving the effect of winding up the steel cable. After the steel cable is wound up, the limit pin on the handle can be slid into the limit hole at the corresponding position, thereby completing the fixation of the winch, preventing the steel cable from moving, and ensuring the stable display of the background board.

[0010] The utility model is further configured as follows: support rods are fixed at the bottom of the display rack 1 and the display rack 2, a plurality of support feet are fixed obliquely at equal intervals along the circumferential direction at the bottom of the support rods, and pulleys are rotatably connected at the bottom of the plurality of support feet.

[0011] By adopting the above technical solution, the setting of several supporting feet can provide balanced supporting force for the supporting rod, so that the background board can be placed more stably. At the same time, the setting of the pulley allows the staff to easily move the background board to the position where it needs to be displayed.

[0012] The utility model is further configured as follows: slot 1 and slot 2 are respectively provided on the top of the inner walls of through slot 1 and through slot 2, and stop pin 1 and stop pin 2 are respectively slidably connected in slot 1 and slot 2, and stop pin 1 and stop pin 2 are both provided with arc surfaces vertically upward, and a limiting cavity 1 for placing the steel cable is formed between stop pin 1 and the top of through slot 1, and a limiting cavity 2 for placing the steel cable is formed between stop pin 2 and the top of through slot 2, and pressure plates are fixed on the outer peripheral walls of stop pin 1 and stop pin 2, and elastic parts are provided between the inner walls of slot 1 and slot 2 and the pressure plates, and one ends of stop pin 1 and stop pin 2 extend out of the display frame and are respectively fixed with pull rod 1 and pull rod 2, and the elastic parts in this embodiment are compression springs.

[0013] By adopting the above technical solution, when it is necessary to place the background board, the staff can first place the steel cable on the second stop pin and the first stop pin, that is, the steel cable is in the second limit cavity and the first limit cavity, and the steel cable is in the highest position in the vertical direction, so that the display cavity height reaches the maximum value. At this time, the staff can directly move the background board into the slot, and then reel in the steel cable by rotating the hinge wheel, driving the steel cable placed on the second stop pin and the first stop pin to be squeezed downward. Due to the guiding effect of the arc surface, the steel cable presses the second stop pin and the first stop pin into the second slot and the first slot respectively, and the steel cable can be separated from the second limit cavity and the first limit cavity and continue to approach the background board, so that there is no need to adjust the position of the steel cable during the placement of the background board, thereby realizing the rapid installation of background boards of different sizes.

[0014] In addition, when the steel cable just moves away from stop pin 1 and stop pin 2, stop pin 1 and stop pin 2 will automatically reset under the elastic force of the compression spring. When the background board needs to be re-placed, the staff only needs to pull rod 1 to put the steel cable back into limit cavity 1, and pull rod 2 to put the steel cable back into limit cavity 2, so that the height of the display cavity returns to the maximum value, thereby facilitating the replacement of background boards of different sizes.

[0015] The utility model is further configured as follows: a slide groove for accommodating the steel cable is provided on the display rack 1 and the display rack 2, and a limit buckle is fixed at the position of the slide groove corresponding to the display rack 1 and the display rack 2.

[0016] By adopting the above technical solution, through the guiding effect of the slide groove and the limiting effect of the limit buckle, the steel cable will not deviate from the slide groove during the winding process, and the staff can wind up the steel cable more smoothly, making the installation process of background boards of different sizes smoother.

[0017] The beneficial effect of the utility model is that when placing background boards of different sizes, the staff first inserts the background boards into the slots of the display rack one and the display rack two, and places the background boards on the support platform. Then the staff can adjust the distance between the display rack one and the display rack two, and the position of the steel cable in the through slot one and the through slot two according to the size of the background boards, and then reel in the steel cable through the reeling mechanism. During the reeling process, the steel cable wrapped around the outside of the background board drives the display rack one and the display rack two to approach each other and fit closely to the background board, and at the same time, the steel cable presses the background board downward, thereby completely fixing the background board in the display cavity, so that the background board bracket can be used for displaying background boards of different sizes, and has high adaptability.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0028] like Figure 1 , 3 As shown in Figure 6, a background board bracket comprises a display frame 1 and a display frame 2, a steel cable 3 is arranged at the bottom of the display frame 1, a through hole 30 for the steel cable 3 to pass through is opened at the bottom of the display frame 22, and a through slot 25 for the steel cable 3 to pass through is opened at the top along the vertical direction, a through slot 4 for the steel cable 3 to pass through is opened at the top of the display frame 1 along the vertical direction, a winding mechanism connected to one end of the steel cable 3 is fixed on one side of the display frame 1, one end of the steel cable 3 is fixed to the bottom of the display frame 1, the other end passes through the through hole 30 and passes through the through slot 25 from the outside to the inside from the outside of the display frame 22, and then passes through the through slot 14 at any time, and finally is connected to the winding mechanism on the outside of the display frame 1, a card slot 7 for the background board to be inserted is opened on the opposite sides of the display frame 1 and the display frame 2, a support platform 8 for supporting the background board is fixed at the bottom of the card slot 7, and a display cavity 6 for loading the background board is formed between the steel cable 3, the display frame 1 and the display frame 2.

[0029] When it is necessary to place a background board, the staff can first adjust the distance between the display frame 1 and the display frame 2 to adapt to the background board, then snap the background board into the card slots 7 of the display frame 1 and the display frame 2, and place the background board on the support platform 8. Then the staff can roll up the steel cable 3 through the winding mechanism. The steel cable 3 wrapped around the outside of the background board drives the display frame 1 and the display frame 2 to approach each other and close to the background board during the winding process, and at the same time makes the steel cable 3 press the background board downward, so that the background board is completely fixed in the display cavity 6. When placing background boards of different sizes, the distance between the display frame 1 and the display frame 2 can be freely adjusted according to the change of the size of the background board, and the steel cable 3 can also move freely in the through slot 1 4 and the through slot 2 5 according to the change of the size of the background board, thereby changing the size of the display cavity 6, so that the background board bracket can be used for displaying background boards of different sizes, and has high adaptability.

[0030] like Figure 2 As shown, the winding mechanism includes two baffles 9 fixed to the outside of the display frame 1, a rotating shaft 10 is rotatably connected between the two baffles 9, a capstan 11 is fixed on the rotating shaft 10, one end of the rotating shaft 10 extends out of the baffle 9 and is fixed with a handle 12, a limit pin 13 is slidably connected to the handle 12, and a plurality of limit holes 14 for inserting the limit pin 13 are opened on the display frame 1.

[0031] When the winding mechanism needs to wind up the steel cable 3, the staff can rotate the handle 12. The rotation of the handle 12 drives the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the winch 11 to rotate. The rotation of the winch 11 causes the steel cable 3 fixed on the winch 11 to be wound on the winch 11, thereby achieving the effect of winding up the steel cable 3. After the steel cable 3 is wound up, the limit pin 13 on the handle 12 can be slid into the limit hole 14 at the corresponding position, thereby completing the fixation of the winch 11, preventing the steel cable 3 from moving, and ensuring the stable display of the background board.

[0032] like Figure 1 As shown, a support rod 15 is fixed at the bottom of the display rack 1 and the display rack 2 2 , and a plurality of support legs 16 are fixed at equal intervals and tilted at the bottom of the support rod 15 along the circumferential direction, and a pulley 17 is rotatably connected to the bottom of the plurality of support legs 16 .

[0033] The provision of a plurality of support legs 16 can provide a balanced support force for the support rods 15, thereby making the background board more stably placed. Meanwhile, the provision of the pulley 17 enables the staff to easily move the background board to the desired display position.

[0034] like Figure 4 and Figure 7 As shown, the top of the inner wall of the through slot 14 and the through slot 25 is provided with a slot 18 and a slot 2 19, respectively, and the slot 18 and the slot 2 are slidably connected with a stop pin 1 20 and a stop pin 21, respectively, and the stop pin 1 20 and the stop pin 21 are provided with arc surfaces vertically upward. 31, a limit cavity 1 22 for placing the steel cable 3 is formed between the stop pin 1 20 and the top of the through slot 14, and a limit cavity 23 for placing the steel cable 3 is formed between the stop pin 21 and the top of the through slot 25, and a pressure plate 24 is fixed on the outer peripheral wall of the stop pin 1 20 and the stop pin 21, and an elastic member 25 is provided between the inner wall of the slot 18 and the slot 2 19 and the pressure plate 24, and one end of the stop pin 1 20 and the stop pin 21 is extended to the outside of the display frame and fixed with a pull rod 1 28 and a pull rod 29, respectively, and the elastic member 25 in this embodiment is a compression spring.

[0035] When it is necessary to place the background board, the staff can first place the steel cable 3 on the second stop pin 21 and the first stop pin 20, that is, the steel cable 3 is in the second limit cavity 23 and the first limit cavity 22, and the steel cable 3 is in the highest position in the vertical direction, so that the height of the display cavity 6 reaches the maximum value. At this time, the staff can directly move the background board into the card slot 7, and then reel in the steel cable 3 by rotating the hinge wheel, driving the steel cable 3 placed on the second stop pin 21 and the first stop pin 20 to squeeze downward. Due to the guiding effect of the arc surface 31, the steel cable 3 presses the second stop pin 21 and the first stop pin 20 into the second slot 19 and the first slot 18 respectively, and the steel cable 3 can be separated from the second limit cavity 23 and the first limit cavity 22 and continue to approach the background board, so that there is no need to adjust the position of the steel cable 3 during the process of placing the background board, thereby realizing the rapid installation of background boards of different sizes.

[0036] In addition, when the steel cable 3 just moves away from the stop pin 1 20 and the stop pin 21, the stop pin 1 20 and the stop pin 21 are automatically reset under the elastic force of the compression spring. When the background board needs to be re-placed, the staff only needs to pull the pull rod 1 28 to put the steel cable 3 back into the limit cavity 1 22, and pull the pull rod 2 29 to put the steel cable 3 back into the limit cavity 2 23, so that the height of the display cavity 6 returns to the maximum value, thereby facilitating the replacement of background boards of different sizes.

[0037] like Figure 3 and Figure 6 As shown, both the display rack 1 1 and the display rack 2 2 are provided with a slide groove 26 for accommodating the steel cable 3, and the display rack 1 1 and the display rack 2 2 are fixed with a limit buckle 27 at the position corresponding to the slide groove 26. Through the guiding effect of the slide groove 26 and the limiting effect of the limit buckle 27, the steel cable 3 will not deviate from the slide groove 26 during the winding process, and the staff can wind up the steel cable 3 more smoothly, making the installation process of background boards of different sizes smoother.

[0038] Working principle:

[0039] When it is necessary to place a background board, the staff can first adjust the distance between the display rack 1 1 and the display rack 2 2 to fit the background board, and then put the steel cable 3 on the stop pin 2 21 and the stop pin 1 20, that is, the steel cable 3 is in the limit cavity 23 and the limit cavity 1 22, and the steel cable 3 is in the highest position in the vertical direction, so that the height of the display cavity 6 reaches the maximum value. At this time, the staff can clip the background board into the slot 7 of the display rack 1 1 and the display rack 2 2, and place the background board on the support platform 8. Then the staff can reel in the steel cable 3 through the reeling mechanism, and the steel cable 3 is guided and limited by the slide groove 26 and the limit buckle 27. When used, it can be smoothly reeled up, thereby driving the steel cable 3 placed on the second stop pin 21 and the first stop pin 20 to be squeezed downward. Due to the guiding effect of the arc surface 31, the steel cable 3 presses the second stop pin 21 and the first stop pin 20 into the second slot 19 and the first slot 18 respectively, and the steel cable 3 can be separated from the second limit cavity 23 and the first limit cavity 22 and continue to approach the background board. Due to the setting of the pulley 17, the steel cable 3 surrounding the outside of the background board drives the display frame 1 and the second display frame 2 to approach each other and stick to the background board during the reeling process, and at the same time, the steel cable 3 presses the background board downward, thereby completely fixing the background board in the display cavity 6.

[0040] Furthermore, when placing background boards of different sizes, the distance between display frame 1 and display frame 2 can be freely adjusted according to the change of the size of the background board, and the steel cable 3 can also move freely in through groove 1 4 and through groove 2 5 according to the change of the size of the background board, thereby changing the size of the display cavity 6, so that the background board bracket can be used for displaying background boards of different sizes.

[0041] Finally, due to the setting of the pulley 17, the staff can move the background board to the position where it needs to be displayed.

[0042] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model.
