Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lamp box cloth, especially to an outer-punched lamp box cloth assembly. BACKGROUND

[0002] Lamp box cloth is a kind of cloth commonly used for displaying text or pattern information on storefront lights, advertising sites, etc., which can be divided into inner-punched lamp box cloth and outer-punched lamp box cloth according to different usage methods. Inner-punched lamp box cloth, also known as inner-lamp cloth, is generally used for lighting from the inner cavity of the cloth, such as the lamp box cloth on the storefront light. Outer-punched lamp box cloth is generally lit from the outer side or pattern side of the cloth to illuminate and display the information on the cloth.

[0003] In the prior art, a Chinese patent with publication number CN218069279U and publication date of December 16, 2022 is proposed, which specifically discloses a lamp box cloth assembly. The lamp box cloth assembly is an outer-punched lamp box cloth, which specifically includes a box body, multiple taking and placing racks, a retractable drum, and a lamp box cloth. The lower end of the lamp box cloth is connected to an auxiliary shaft, the U-shaped taking and placing rack is installed on the box body, and the retractable drum is horizontally installed on the taking and placing rack. The lamp box cloth is installed in a roll on the retractable drum. Although this scheme can achieve the switching and display of multiple lamp box cloths by setting multiple taking and placing racks, retractable drums, and lamp box cloths in the box body, thereby meeting the user's demand for multi-aspect display effect. However, there are still some potential defects when it is used with an outer-punched lamp. The positions of the multiple retractable drums relative to the box body are fixed, and the positions of the lamp box cloths on the box body are also fixed. When switching different lamp box cloths, the distance of each lamp box cloth relative to the outer-punched lamp changes, which affects the display effect of the lamp box cloth. If multiple outer-punched lamps are set, the weight of the assembly increases, and the use cost also increases. UTILITY MODEL CONTENT

[0027] The embodiments of the present application will be described in detail below with reference to the drawings. The features in the following embodiments can be combined with each other without conflict.

[0028] Referring to Figures 1 to 2 The embodiment provides an external printing light box cloth assembly, which comprises a box body 1 in a rectangular shape and an upper winding drum 40 and a lower winding drum 41 arranged oppositely and parallel in the box body 1, the upper winding drum 40 and the lower winding drum 41 are both provided with light box cloths 404 wound thereon, the two light box cloths 404 can be provided with different graphic information sprayed, the bottom of the box body 1 is provided with a strip-shaped opening 11 for the light box cloth to pass out, and one side of the box body 1 adjacent to the opening 11 is further provided with an external printing light 132, one end of the external printing light 132 is connected with a connecting frame 13. The two side walls of the box body 1 opposite to the upper winding drum 40 are both provided with upper guide rails 20 extending horizontally along the width direction of the box body 1, each of the upper guide rails 20 is provided with an upper guide seat 21 matched therewith, and the upper winding drum 40 is rotatably connected between the two upper guide seats 21. The two side walls of the box body 1 opposite to the lower winding drum 41 are both provided with lower guide rails 30 arranged oppositely and parallel to the upper guide rails 20, each of the lower guide rails 30 is provided with a lower guide seat 31 matched therewith, and the lower winding drum 41 is rotatably connected between the two lower guide seats 31. Switching mechanisms are arranged between the upper guide rails 20 and the lower guide rails 30 on the same side, and the switching mechanisms are connected with the upper guide seats 21 and the lower guide seats 31 to drive the upper winding drum 40 and the lower winding drum 41 to move towards the side of the opening 11 alternately.

[0029] Specifically, referring to Figure 3 The switching mechanism comprises switching chains 5 and sprockets 501 matched with the switching chains 5, the sprockets 501 are rotatably connected to the side walls of the box body 1, one of the sprockets 501 is connected with a reciprocating motor 502 through a rotating shaft, the switching chains 5 comprise upper chain segments and lower chain segments wrapped around the two sides of the corresponding sprockets 501, the upper guide seats 21 are connected with the upper chain segments, and the lower guide seats 31 are connected with the lower chain segments. In use, the reciprocating motor 502 is started to drive the sprockets 501 to rotate, and the upper guide seats 21 and the lower guide seats 31 are driven by the switching chains 5 to move reversely, so that the upper winding drum 40 and the lower winding drum 41 can move towards the side of the opening 11 alternately to switch different light box cloths.

[0030] Specifically, the upper winding drum 40 and the lower winding drum 41 adopt the same structure and both comprise a drum body 401 and a connecting rod 402, the drum body 401 is connected between the corresponding guide seats through the connecting rod 402, and the connecting rod 402 is provided with a rotating motor 403 for driving the corresponding drum body 401 to rotate. The rotating motor 403 is driven to rotate to drive the drum body 401 to rotate, so that the winding of the light box cloth or the release of the light box cloth from the drum body 401 is realized.

[0031] Specifically, a support frame 406 is arranged below the cylinder body 401, and a strip-shaped hole is arranged on the support frame 406. The lower part of the light box cloth 404 is provided with a hanging shaft 405, which mainly functions to apply a certain tension to the light box cloth 404, so as to prevent the light box cloth 404 from being loose or having flow marks on the surface, and make the light box cloth 404 tightly wrap around the cylinder. Meanwhile, the hanging shaft 405 facilitates the light box cloth 404 to be pulled out of the opening and to be unfolded. The light box cloth 404 passes through the corresponding strip-shaped hole, and the hanging shaft 405 is stopped below the strip-shaped hole. In this way, when the corresponding cylinder moves to the opening, the hanging shaft 405 can be aligned with the opening, so as to facilitate the light box cloth 404 to be pulled out of the opening.

[0032] Reference Figure 3 and 4 As shown in FIG. 6, in order to prevent interference or collision between the upper cylinder 40 and the lower cylinder 41 during relative movement, an L-shaped mounting seat 6 is arranged on the lower guide base 31, and the lower cylinder 41 is connected to the mounting seat 6. A avoiding mechanism 7 is arranged between the mounting seat 6 and the corresponding lower guide base 31, and is adapted to drive the mounting seat 6 to move downward, so that the lower cylinder 41 can avoid the upper cylinder 40 during relative movement. As an extension, the mounting seat 6 can also be installed on the upper guide base 21. In this case, the avoiding mechanism 7 is arranged between the mounting seat 6 and the corresponding upper guide base 21, and can drive the mounting seat 6 to move upward, thereby preventing interference between the two cylinders during relative movement. This extension is also included in the concept of the present application.

[0033] Specifically, the avoiding mechanism 7 includes a floating rod 71, a limiting roller 72 and a limiting frame 73. The floating rod 71 is connected to the mounting seat 6, and a floating hole is arranged on the lower guide base 31 to allow the floating rod 71 to pass through. The limiting roller 72 is connected to the lower end of the floating rod 71. The limiting frame 73 is provided with a strip-shaped hole 74 for the floating rod 71 to pass through, and the limiting roller 72 is limited to the lower part of the limiting frame 73. A spring 75 is arranged between the floating rod 71 and the lower guide base 31 and wraps around the outer side of the floating rod 71. The spring 75 is a compression spring, which is used to quickly reset the mounting seat 6 after moving downward. Preferably, the floating rod 71 includes a first floating rod and a second floating rod arranged opposite to each other on the mounting seat 6. The lower ends of the first floating rod and the second floating rod are provided with a linkage rod 76, the lower part of the linkage rod 76 is connected to the limiting roller 72, and the spring 75 is arranged between the linkage rod 76 and the lower guide base 31. Such arrangement makes the structure on the lower guide base 31 more balanced and stable.

[0034] In the embodiment, a travel switch 8 is arranged on a side wall of the box body 1, and the travel switch 8 is electrically connected with the reciprocating motor 502 and the two rotating motors 403. The reciprocating motor 502 is controlled to stop by the travel switch 8, and the rotating motor 403 corresponding to the winding drum at the opening is turned on, so that the semi-automatic switching of the automatic light box cloth 404 can be realized.

[0035] In the embodiment, two connecting frames 13 are arranged below the box body 1, and a clamping protrusion 131 is arranged on each connecting frame 13, and a clamping hole matched with the clamping protrusion 131 is arranged on each light box cloth 404. The light box cloth is more stable and reliable when displayed.

[0036] Reference Figure 3 As shown in the drawings, the working principle of the embodiment is as follows: when the light box cloth is switched, the reciprocating motor 502 is turned on to drive the chain wheel 501 to rotate, and the upper guide seat 21 and the lower guide seat 31 are driven by the switching chain 5 to move in opposite directions. Taking the movement of the upper guide seat 21 towards the opening side as an example, when the upper guide seat 21 touches the travel switch 8, the hanging shaft 405 below the upper winding drum 40 is opposite to the opening 11, the travel switch 8 is turned on, the reciprocating motor 502 is controlled to stop, and the corresponding rotating motor 403 is turned on. The upper winding drum 40 rotates to drive the light box cloth 404 on the drum to release downward, the clamping hole on the light box cloth 404 is buckled with the clamping protrusion 131 on the connecting frame 13, and the outer light 132 is turned on to display. Since the two types of light box cloths 404 are out of the box body 1 from the same opening, the distance from the outer light 132 is relatively fixed, so compared with the prior art, the display effect of the light box cloth is more stable and reliable.

[0037] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
