[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] Embodiment 1:

[0031] like Figure 1-Figure 5 As shown, a pull-out light box aluminum profile includes a profile body 1 and a side pressure cover 2. The profile body 1 and the side pressure cover 2 form a canvas groove, and a canvas fixing component for fixing the canvas is provided in the canvas groove. Definition Figure 1 The side pressure cover 2 shown in the figure is in a left-right relationship with the profile body 1.

[0032] The left bottom of the profile body 1 is provided with a buckle groove 14, and the bottom of the side pressure cover 2 is provided with a buckle 24 that is inserted into the buckle groove 14 from one side of the profile body 1. The profile body 1 includes a bottom plate 15 and a side plate 11, which extends obliquely from one side of the bottom plate of the profile body 1 toward the upper left side and forms an abutment portion 110 at the end, which abuts against the frame 21.

[0033] The bottom of the side pressure cover 2 is provided with the aforementioned fastener 24, which is an elastic fastener. The fastener is composed of two spring pieces facing each other, the middle part of the upper spring piece is convex upward, and the middle part of the lower spring piece is convex downward. When subjected to extrusion force, the two spring pieces are relatively squeezed and deformed. The spring piece is a suspended thin sheet structure, so it has a certain elastic deformation ability.

[0034] The part of the side cover 2 located above the fastener is a vertical plate 20, which extends upward and is provided with a frame 21 at the end. The frame 21 extends toward the profile body, that is, in the frame width direction. The width of the frame 21 is less than the width of the bottom plate 15. In this embodiment, the width of the frame is less than half of the width of the bottom plate.

[0035] The frame 21 is a rectangular frame, and the internal holes of the frame are used to fix with the angle brackets, and the angle brackets can be used to butt and fix two horizontal and vertical profiles that are connected to each other, so as to finally form a common rectangular door head structure. In this embodiment, the frame of the upper part of the side pressure cover 2 is narrow, so that the frame of the door head frame formed is a narrow frame.

[0036] The side plate 11 of the profile body 1 is an arc-shaped plate, a reinforcing rib plate is provided inside the arc-shaped plate, and the left part of the side plate is open.

[0037] A limiting plate 22 is provided on the lower side of the frame 21, and the limiting plate 22 extends downward to form a limiting groove with the bottom side of the frame. The top of the side plate 11, i.e. the abutting portion 110, abuts against the limiting groove and presses the position where the canvas extends out of the canvas groove.

[0038] The canvas fixing assembly includes a canvas fixing seat and a fastening bolt. The canvas fixing seat is provided with a slide groove 12, and the bottom sliding limiter of the fastening bolt 3 is assembled in the slide groove 12. The canvas fixing seat is arranged on the upper side of the bottom plate 15, and the bottom plate 15 is arranged tilted, and the tilting direction is from the side pressure cover 2 to the side plate direction. The axis of the fastening bolt 3 is perpendicular to the bottom plate 15. The tilting design of the bottom plate is mainly considered that the side plate of the profile body 1 is an arc plate and the space of the canvas groove is small. In order to prevent the top of the fastening bolt from interfering with the arc plate and facilitate the fixing of the canvas, the fastening bolt is tilted and the matching bottom plate is tilted at the same time.

[0039] The slide groove 12 is a T-shaped groove, and the bottom of the fastening bolt 3 is set to a square piece that matches the slide groove. The square piece can be a rectangular piece or a square piece. The width of the square piece is larger than the width of the upper opening of the T-shaped groove and smaller than the width of the lower groove, so that the fastening bolt can slide in the slide groove, prevent it from falling out, and prevent it from rotating, so that the canvas can be fixed to the fastening bolt. The fastening bolt can move and change its position in the slide groove as the canvas is installed, so that the canvas can be installed in place and the rigid installation can be prevented from tearing the canvas.

[0040] A clamping piece is provided on the upper part of the fastening bolt 3 for fixing the canvas. The clamping piece is a combination of a nut 5 and a gasket 4. A double nut can also be used to clamp and fix the canvas passing through the fastening bolt.

[0041] The snap-fit ​​groove 14 at the bottom of the profile body 1 is an open groove facing the side cover plate, and the upper and lower sides of the open groove are provided with limit points 141, and the groove becomes narrower at the upper and lower limit points. The fastener can pass the limit point and snap into the open groove under the action of external force, and the protrusion of the fastener 24 passes the limit point, and the limit point and the fastener protrusion cooperate to achieve the clamping. The upper edge of the notch of the snap-fit ​​groove 14 is provided with a rib 13, which fits with the side pressure cover 2 and plays a positioning role. The side pressure cover 2 is snapped into the rib position, that is, it is snapped into place. A limit protrusion 23 is also provided on the inner side of the side pressure cover 2, which is just located on the upper side of the rib 13.

[0042] When the aluminum profile of the cloth light box of the present invention is used, multiple sections of aluminum profiles are connected to form a light box frame. The side of the canvas extends into the canvas groove and is fixed by the clamping piece on the fastening bolt, and then the side pressure cover 2 is buckled on, and the bottom of the side pressure cover 2 is snapped into the buckling groove at the bottom of the profile body 1. The limiting notch on the side pressure cover 2 just matches the abutment part on the upper part of the side plate of the profile body 1. Figure 6 As shown, it is a schematic diagram of a portion of a light box equipped with a canvas, and the frame on the upper part of the side pressure cover 2 is a relatively obvious narrow frame effect. Moreover, the aluminum profile of the cloth light box of the present invention has a relatively simple structure.

[0043] In other embodiments, the slide groove may also be configured as a dovetail groove, and the bottom of the fastening bolt may be configured as a conical piece that matches the slide groove, that is, the cross section of the conical piece is conical and matches the dovetail groove.

[0044] Embodiment 2:

[0045] The difference from Example 1 is that the shape of the profile body is Figure 7 As shown, the side plates of the profile body can also be set as inclined plates, rather than being limited to arc-shaped plates. Considering the impact of the side plates and the fastening bolts, the length of the fastening bolts can be selected to be shorter.

[0046] Embodiment 3:

[0047] The difference from the first embodiment is that the bottom plate of the profile body is, in this embodiment, the bottom plate 15 is arranged horizontally. Considering the influence of the side plate and the fastening bolts, the length of the fastening bolts can be selected to be shorter.

[0048] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that are the same or similar to those of the present application fall within the protection scope of the present invention.
