An easy-to-replace lightbox

technical field

The utility model relates to advertising propaganda equipment, in particular to a light box which is easy to replace advertisements.

Background technique

Advertising light boxes are used as a kind of advertising propaganda device in more and more occasions, such as streets, stations, airports, etc. However, the propaganda pictures of advertising boxes currently used in the market are relatively fixed, which is not convenient for multiple advertisements to replace propaganda and propaganda. The information is limited, the form is monotonous, the style is single, lacks beauty and novelty, and is not attractive enough; the previous product body occupies a large area and is short. In the prior art, when replacing the advertisement in the advertising light box, multiple people are required to perform auxiliary replacement, which will increase the labor cost.

In view of the above problems, a Chinese patent with publication number CN209843166U discloses an advertising light box, which relates to the technical field of light boxes and includes a box body, a first box cover, a second box cover, a first telescopic assembly and a second telescopic assembly; the first The box cover and the second box cover are respectively covered on two opposite sides of the box body; one end of the first box cover is pivotally connected with the box body, and the other end is connected with the box body through the first telescopic assembly; Under the condition that the box cover is opened, the first telescopic assembly is supported between the first box cover and the box body, and locks the relative position between the first box cover and the box body; one end of the second box cover is pivotally connected to the box body , the other end is connected with the box body through the second telescopic assembly; the second telescopic assembly is configured so that when the second box cover is opened, the second telescopic component is supported between the second box cover and the box body, and locks the second box cover. The relative position between the cover and the box.

The advertising light box of the above scheme can be opened and closed quickly through the simple opening and closing method of pulling the box cover, and at the same time, the labor cost is saved, and the replacement of advertisements is more convenient.

At the same time, the utility model proposes a new solution to solve this problem.

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a light box that is easy to replace advertisements. As soon as the cover plate is opened, the purpose of convenient replacement of advertisements is achieved.

The above technical purpose of the present utility model is achieved through the following technical solutions: a light box that is easy to replace advertisements, including a frame, and two sides of the frame are respectively provided with a cover plate 1 and a cover plate 2 that are slidably connected to the light box. The upper end of the frame is provided with a cavity 1 along the width direction, and one end of the cavity 1 is provided with a rotating rod that is rotatably connected with it. A pull rope that is fixedly connected, the other end of the cavity one is provided with a driving block that is slidably connected to it, the other end of the pull rope is fixedly connected to the driving block, and the frame is provided with a driving block for extending and moving. In the moving groove, one end of the driving block protruding from the moving groove is fixedly connected to the cover plate, and an elastic member is provided between the end of the driving block far away from the rotating rod and the first cavity.

By adopting the above technical solution, the advertisement sheet will be placed in the cavity enclosed by the frame, the first cover plate and the second cover plate. A motor is installed in the first cavity, and one end of the rotating rod and the output shaft of the motor pass through a coupling When the advertisement needs to be replaced, start the motor to drive the rotating rod to rotate. After the rotating rod rotates, it will drive the installation block to rotate. After the installation block rotates, it will drive the pull rope to wrap around the rotating rod, and the length of the pull rope will be shortened. The pull rope will pull the driving block to the side close to the rotating rod, and the elastic piece between the driving block and the inner wall of the cavity will be stretched out. After moving, the interior space of the light box is opened, and the advertisements in the chamber can be taken out and replaced. After the replacement is completed, the rotating rod is driven to rotate in the opposite direction by the motor, and the pull rope wrapped around the rotating rod will be loosened. The elastic member will pull the driving block to the side away from the rotating rod through its own elastic force, and the cover will move back to its original position under the driving of the driving block, so that the cover can be moved by the motor, which is convenient Replace the ad.

By adopting the above technical solution, during the movement of the second cover plate, the bumps are inserted into the slide rails and move together with the second cover plate, so that the second cover plate is more stable during the movement.

The utility model is further configured as follows: a protective cover is arranged outside the pulling rope.

By adopting the above technical solution, the protective cover is made of rubber, which has good elasticity and will not affect the use of the pull rope, and at the same time, the wear of the pull rope during use is reduced, and the service life of the pull rope is prolonged.

The utility model is further provided as follows: a plurality of universal balls 1 distributed in an array are arranged on the inner wall of the limiting groove, and the universal balls 1 are attached to the surface of the limiting block.

By adopting the above technical solution, during the movement of the limit block along the limit groove, the universal ball will roll against the surface of the limit block, reducing the friction between the limit block and the limit groove, so that the The movement of the limit block is smoother.

The utility model is further configured as follows: the inner wall of the slide rail is provided with a plurality of second universal balls distributed in an array, and the second universal ball is attached to the surface of the convex block.

By adopting the above technical solution, when the bump moves along the slide rail, the second universal ball will roll against the surface of the bump, reducing the friction between the bump and the slide rail, and making the movement of the bump more efficient. smooth.

The utility model is further provided as follows: an accommodating groove is arranged on the inner wall of the frame.

By adopting the above technical solution, when the advertisement sheet is put into the frame, the edge of the advertisement sheet can be snapped into the accommodating groove, so that the placement of the advertisement sheet is more stable.

To sum up, the utility model has the following beneficial effects:

The advertisement list will be placed in the cavity formed by the frame, cover plate 1 and cover plate 2. A motor is installed in cavity 1, and one end of the rotating rod is connected with the output shaft of the motor through a coupling. When replacing, start the motor to drive the rotating rod to rotate. After the rotating rod rotates, it will drive the installation block to rotate. After the installation block rotates, it will drive the pull rope to wrap around the rotating rod. The length of the pull rope will be shortened, and the pull rope will drive the When the block is pulled to the side close to the rotating rod, the elastic piece between the driving block and the inner wall of the cavity will stretch out. After the driving block moves, it will drive the cover plate to move, and the cover plate moves to one side. Once it is opened, the advertisement in the chamber can be taken out and replaced. After the replacement is completed, the rotating rod is driven to rotate in the opposite direction by the motor. The elastic force of the driving block will pull the driving block to the side away from the rotating rod, and the cover will move back to its original position under the driving of the driving block, so that the cover can be moved by the motor, and the advertisement can be easily replaced.
