[0024] like Figure 1-5 The first embodiment of the utility model is shown: an arbitrary-angle axisless rolled photo frame back buckle, an upper sheet 1 and a lower sheet 2, one end of the lower sheet 2 is bent into an outer roll 201, one end of the upper sheet 1 is bent into an inner roll 101, the inner roll 101 is rotatably connected in the outer roll 201 to form a wrapped axis, a plurality of avoidance cuts 202 are opened on the outer roll 201, an adjustment end 102 that coincides with the avoidance cut 202 is formed between the inner roll 101 and the upper sheet 1, and the adjustment end 102 moves in the avoidance cut 202.
[0025] The present invention eliminates the tongue of the upper material piece and the hole of the lower material piece matched therewith in the existing back buckle, and achieves the opening and closing effect by adopting the method of wrapping the outer curl 201 at one end of the lower material piece 2 around the inner curl 101 at one end of the upper material piece 1 to form a wrapped axis, and an avoidance cut 202 is provided on the outer curl 201, so that the inner curl 101 enters the outer curl 201 through the avoidance cut 202, and the outer curl 201 wraps the inner curl 101 from the outside in the same direction, and the outer curl 201 and the inner curl 101 are wrapped together to form a wrapped axis, and at the same time, an adjusting end 102 is provided between the upper material piece 1 and the inner curl 101, and an avoidance cut 202 is provided on the outer curl 2, so that during the opening and closing process of the lower material piece 2 relative to the upper material piece 1, the upper material piece 1 and the lower material piece 2 can be relatively opened and closed at multiple angles through the cooperation of the adjusting end 102 and the avoidance cut 202, thereby realizing the opening and closing angle of the photo frame that can be adjusted at will.
[0026] Specifically, two pieces of material are used to form a curl, that is, an axis. The upper piece 1 is rolled into a cylindrical shape in the lower piece 2, and the lower piece 2 wraps the inner curl 101 of the upper piece 1 to form an axis. The friction force generated by the outer curl 201 and the inner curl 101 wrapping each other can effectively control the tightness of the hinge, so that the back panel can maintain the tightness without loosening or sliding down to close during the process of opening to any angle, and the opening and closing angle can be adjusted at will.
[0027] like Figure 2 As shown: the avoidance cuts 202 are arranged on both sides of the outer curl 201, and the inner curl 101 at one end of the upper sheet 1 enters into the outer curl 201 through the avoidance cuts 202. And different opening and closing angles can be controlled by setting different sizes of the avoidance cuts 202.
[0028] like Figure 1 As shown: the upper sheet 1 and the lower sheet 2 are symmetrically provided with flower claws 3, and the flower claws 3 on the upper sheet 1 and the lower sheet 2 are arranged oppositely, and the sheet can be conveniently fixed on the supporting legs and the back of the outer frame through the flower claws 3.
[0029] like Figure 4-5 As shown: a slope 103 is formed between the upper sheet 1 and the adjustment end 102. The slope 103 is provided on the upper sheet 1 so that the back plate support legs can fit more closely when the product is in a closed state during use.
[0030] like Figure 3 As shown: a plurality of reinforcing ribs 104 are provided on the upper sheet 1, and the reinforcing ribs 104 are used to enhance the strength of the sheet so that it will not deform during use.
[0031] like Figure 3As shown: the upper sheet 1 is provided with a plurality of convex positions 105, and the convex positions 105 are concave in the surface of the upper sheet 1, so as to avoid the product being too tightly attached after closing when the surface of the product is subjected to coloring treatment, which would affect the inner treatment during the surface treatment.
[0032] Based on the above description, this kind of arbitrary angle shaftless roll-up photo frame back buckle is more convenient and flexible in the use of various parts. The opening and closing angle is arbitrary, which solves the technical problem of product opening and closing not being smooth and unable to adjust the angle at will. After the two pieces of the roll-up roll themselves up, they wrap around each other to form a self-rolling axis. No pin is required. The self-rolling circle friction is used to control the opening and closing. The opening and closing is smooth, and the self-rolling circle wraps the axis to open and close smoothly. The angle can be adjusted at will. It will not be controlled by the tongues designed on both sides like the traditional back buckle, which will not get stuck when used.
[0033] In order to make the legs fit closely after closing, there is a slope 103 on the upper piece 1. When the back buckle is closed, the upper piece 1 will tilt inward, and the lower end of the back buckle will close more tightly. The avoidance cut 202 allows the upper piece 1 to pass through the avoidance cut 202 and enter the lower piece 2. It also controls the angle when the back buckle is opened and closed, so that the back buckle will not be unable to stand up due to too large an angle.
[0034] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
