Description

 Easy to fight

Technical field

 The utility model faces the frameless and the screen without gap splicing. The roll-up is related to a portable exhibition display material. Background technique

 Nowadays, self-presentation at major exhibitions has become a very important way for companies to establish their image in the industry, and display equipment has gradually become an important part of commercial promotion. In addition, in the context of lectures, seminars, etc., it is also necessary to use the physical image to set off and display.

 The so-called traditional roll-up is a popular portable display device in recent years. Its structure mainly consists of a casing, which can be used for loading the inside of the painting. The lower end of the painting is fixed in the casing with a roller with elastic stretching device. On the upper side of the painting, the upper end of the painting is fixed on the hanging drawing strip for drawing. When the shell is used as the base, a vertical rod is inserted into the hole of the outer casing to fix the drawing, and the hanging strip is fixed on the top of the pole. The elastic device inside the outer casing tightens the painting, and the painting is used to draw the painting into the outer casing. It is an easy to carry and easy to display device. When the customer splicing several pictures, to achieve the effect of two or three meters wide painting wall, because the end of the roll-up shell has an end cover to fix the elastic device, the outer casing must be wider than the picture, so that when the picture is displayed, the audience is easy When you see the end cover of the outer casing or the casing part of the outer casing, a large gap is inevitable between the screen and the screen during splicing, which affects the overall display effect of the screen.

 In addition, the conventional type of roll-up has a rectangular structure in a plan view, which makes it possible to display only a flat picture when combined, rather than a surrounding type picture which is more suitable for viewing. Summary of the invention

 The technical problem to be solved by the utility model is that, on the basis of inheriting the basic technical features of the traditional type of roll-up, the effect of the frame-type picture with no frame and no gaps in the picture is realized.

In order to solve the above technical problem, the present invention provides a front view frameless and pictureless gapless splicing roll-up, including a casing, a flip cover, a card position mechanism and a support leg, wherein the lower part of the top view of the roll-up, ie, the roll-up The front part is an isosceles trapezoidal structure with a short front and a long length. The front edge is equal to the width of the picture, so that the front frame is framed and painted. No gap splicing between the face and the picture;

 In order to display the effect on the screen, the flip cover is connected to the outer casing through the connecting shaft provided at the rear end, and is respectively inserted into the sleeve provided inside the outer cover of the outer casing, and the inside of the outer casing and the flip cover A chamber is formed with a gap between the front edge of the flap and the outer casing for the passage of the screen.

 The isosceles trapezoidal bottom angle is not more than 75°. When a plurality of gapless stitching of the utility model is placed at the end, a picture wall of not more than 150° is formed between the screens.

 The latching mechanism includes a latching leg disposed at both ends of the flip cover and a latching portion of the securing latching leg disposed on the inner side of the end cap, so that the flip cover is turned down and fixed, and the outer casing is closed.

 Wherein, the flip cover has two flap end caps, and the clip legs are fixed to the inner side of the flip cover end by a spring between the pressure plate and the pressure plate and the card foot.

 In order to facilitate the drawing of the drawing shaft, the supporting leg is a leg provided on the inner side of the flip cover, rotating around the supporting point and supporting the flip cover, thereby supporting the flip cover. '

 The advantage of the utility model is -

1. When multiple pull-ups are placed on the end, there is no gap between the picture and the picture to make the picture more continuous, beautiful and vivid;

 2. When the screen is displayed, the audience no longer sees the roll-up itself on the front, improving the display effect.

 3. There is a certain angle between the display screens to form a surrounding painting wall that is more suitable for viewing. DRAWINGS
