DETAILED DESCRIPTION OF EMBODIMENTS
Further description is made for the present invention in combination with the drawings of the description.
The decorative frame of the present invention, as shown in FIGS. 1-4, comprises a lining plate 1, wherein a layer of tensioned elastic film 2 is covered at one side of the lining plate 1, an interlayer is formed between the lining plate 1 and the elastic film 2, an inserting opening 4 of the interlayer is left at the edge of the lining plate 1 and the elastic film 2, the lining plate 1 or/and the elastic film 2 is/are transparent, and the paintings, photos and others are inserted into the interlayer between the lining plate 1 and the elastic film 2 through the inserting opening, so that the paintings, the photos and others in the interlayer can be saw through the lining plate 1 or/and the elastic film 2; and further treatment, such as flocking and the like, can be carried out on the lining plate 1 or the elastic film 2 on the premise that the paintings and the photos in the interlayer can be saw according to the situations.
As the further improvement and supplement of the above technical solution, the present invention further comprises additional technical features involved in paragraphs below. FIGS. 1-3 and FIG. 4 contain all additional technical features below and are the better embodiment of the present invention, but the present invention is not limited to the situation. Therefore, FIGS. 1-3 and FIG. 4 can be selected for the technical solution in the previous paragraph according to the specific effect when implementing the present invention.
Firstly, the edge of the elastic film 2 is fixed at the edge of the lining plate 1 by virtue of the clipping strips 3, so that the part that the elastic film 2 is located between the clipping strips 3 is tensioned. In the specific implementation, two ways can be provided to fix the edge of the elastic film 2 at the edge of the lining plate 1 by virtue of the clipping strips 3:
One way is (see FIGS. 1-3): the edge of the elastic film 2 is covered at the edge of the lining plate 1, entrapped at the edge of the lining plate 1 by the clipping strips, and spliced or welded with the lining plate 1 and the clipping strips 3 (such as ultrasonic welding).
The other way is (see FIG. 4): each clipping strip 1 comprises an internal insertion strip 31 and an external insertion strip 32, the edge of the elastic film 2 is extruded between the internal insertion strip 31 and the external insertion strip 32, and the internal insertion strip 31 is clamped at the edge of the lining plate 1. Further, the external insertion strip 32 is provided with an inserting groove 33, the internal insertion strip 31 is provided with a convex rib 34, the edge of the elastic film 2 is wound on the convex rib 34 of the internal insertion strip 31, the convex rib 34 of the internal insertion strip 31 is embedded in the inserting groove 33 of the external insertion strip 32, and the edge of the elastic film 2 is extruded between the internal insertion strip 31 and the external insertion strip 32. This structure is convenient for users to assemble: the edge of the elastic film 2 is fixed on the two clipping strips, the elastic film 2 is tensioned by the two clipping strips, and the two clipping strips are clamped at the edge of the lining plate.
Secondly, the decorative frame comprises a standby clipping strip which is clamped at the edge of the lining plate 1 that the clipping strips are not assembled. The standby clipping strip is used for entrapping another two parallel sides after the paintings and the photos are placed insides and carrying out the moisture protection on placed products, thereby effectively isolating the influence of dryness and humidity change outside the frame on works in the frame.
Thirdly, the decorative frame comprises a support component 6. See FIG. 5. The support component 6 comprises a retaining strip 61 and a landing leg 62, the retaining strip 61 is assembled on the clipping strips 3, at least two gears 63 are arranged on the retaining strip 61, and the landing leg 62 is assembled on one gear of the retaining strip 61. Further, a track 64 with a guiding convex rib 65 is arranged on the back of the retaining strip 61, the gear 63 is a bump distributed on the track 64, a gap 66 is arranged at the end of the landing leg 62, a guide groove matched with the guiding convex rib 65 and a locating groove matched with the bump are arranged in the gap 66, and the angle adjustment of the decorative frame is realized by adjusting the position of the landing leg on the retaining strip. The assembly mode of the retaining strip 61 and the clipping strips 3 is one of clamping, insertion and fastener connection or a combination of at least two modes (FIG. 5 shows a structural style that a connecting plug 67 is arranged at the lower end of the retaining strip 61 and a clamping convex rib 68 is arranged on the connecting plug, and correspondingly, a corresponding slot for fixing the connecting plug is arranged on the clipping strips); and apparently, the retaining strip 61 can also be assembled with the standby clipping strip, thereby realizing the angle adjustment of the decorative frame.
Fourthly, the clipping strips are of structures having two parallel sides 36 and forming a clamping slot 37 between the two sides 36, and the edge of the lining plate 1 is located in the clamping slot 37, thereby realizing the clamping of the clipping strips and the lining plate. Further, with reference to FIG. 6, the mouth of the clamping slot 37 is open (e.g., formed by installing steps inside the two sides), therefore, the edge of the lining plate 1 is easily inserted into the clamping slot 37.
Fifthly, an uncovering part 5 is arranged at the edge of the inserting opening that the elastic film 2 is located, so as to open the inserting opening to put in or take out the paintings; and specifically, the uncovering part 5 is a gap or an extension part exceeding the edge of the lining plate 1 or a pulling part corresponding to the gap on the edge of the lining plate 1.
Sixthly, the elastic film 2 is a TUP film; and the lining plate 1 is one of an acrylic plate, a glass plate and a plastic plate.
