[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] Since the utility model relates to the section bar field, the length of the section bar is indefinite, and the section is in a certain shape; therefore, the embodiments of the utility model are mostly presented in the form of a section.

[0030] Embodiment 1: please refer to Figures 1-10 The utility model provides a lamp box frame section bar applied to a single-face cloth clamping lamp box. The section bar is a single-face cloth clamping section bar 3; the lamp box frame is formed by enclosing four single-face cloth clamping section bars 3 with the same section; the single-face cloth clamping section bar 3 is provided with a lamp strip mounting groove 4 on the side facing the enclosure. As shown in the single-face cloth clamping section bar sectional view in the description Figure 1 , the lamp strip mounting groove 4 is mounted at the upper end of the single-face cloth clamping section bar 3. One side of the single-face cloth clamping section bar 3 is provided with a reverse tooth structure 5, and the reverse tooth structure 5 is used for mounting a lamp box canvas 6. As shown in the single-face cloth clamping section bar sectional view in the description Figure 1As shown, the opening direction of the inverted tooth structure 5 is perpendicular to the opening direction of the light strip mounting groove 4. (See attached instruction manual.) Figure 2 As shown, when four single-sided fabric clips 3 form the lightbox frame, the opening direction of the inverted tooth structure 5 points to the direction in which the lightbox canvas 6 is installed, which is also the direction facing the user. The LED strip mounting groove 4 is located inside the frame. Furthermore, as... Figures 3-5 As shown, the upper end of the LED strip mounting groove 4 is symmetrically provided with positioning slots 40, and the LED strip mounting groove 40 is provided with an LED strip assembly 7 inside; the LED strip assembly 7 includes an LED strip body 70 and a terminal block; the upper surface of the LED strip body 70 is symmetrically provided with copper strips 71, and a number of LED beads 72 are arranged between the copper strips; the terminal block is located in the LED strip mounting groove 4 and is in contact with the copper strips for electrical connection.

[0031] The solderless LED strip 7 used in this embodiment can be cut to size as needed, is easy to install, and the wiring terminals connect to the LED strip via a plug-in interface, providing instant illumination. Figures 3-7 As shown, the LED strip terminal has a conductive hole 11 on one side corresponding to the LED strip body 70; the terminal has a conductive piece 12 extending out of the conductive hole 11; after extending out of the conductive hole 11, the conductive piece 12 contacts the copper strip 71 and is energized; one end of the conductive piece 12 is connected to a wire 10, which extends out from the terminal. The wire 10 is used to connect to an external power source to supply power to the LED strip body. In this embodiment, as long as the two conductive pieces 12 of the terminal contact the two symmetrical copper strips 71, the entire LED strip body 70 can be energized, regardless of their position.

[0032] Furthermore, the wiring terminal engages with the LED strip mounting slot 4 to achieve installation and conductive contact with the LED strip body 70. Specifically, this embodiment discloses two types of wiring terminal structures: wiring terminal 1 and wiring terminal 1'.

[0033] The terminal block 1 is provided with a protrusion 13 that engages with the positioning slot 40; the protrusion 13 engages with the positioning slot 40 in a concave-convex fit.

[0034] The terminal block 1' is provided with a pair of elastic flaps 14', and each flap 14' has a corresponding locking wing 15' that engages with the positioning slot 40. When the user squeezes the flaps 14', the terminal block 1' can smoothly enter and exit the light strip mounting slot 4. When the flaps 14' are released, the locking wing 15' will engage with the positioning slot 40 under the action of elasticity. By adopting the above technical solution, the installation quality of the terminal block is improved.

[0035] In this embodiment, the above two types of wiring terminals are connected to the LED strip mounting slot 4 via a plug-in connection to the LED strip body 70, which is convenient, safe, and improves the quality of equipment use.

[0036] Furthermore, an adhesive layer 73 is provided on the bottom surface of the light strip body 70 corresponding to the light strip mounting groove 4, and the positive and negative electrodes of the LED beads 72 are electrically connected to the surfaces of two symmetrical copper strips 71. By adopting the above technical solution, the stability and convenience of installing the light strip body 70 are ensured.

[0037] Furthermore, right-angle brackets 9 are provided at the corners between the lightbox frame profiles, and a portion of the right-angle brackets 9 extends into the single-sided fabric profile 3 for installation and fixation; the edge of the profile surface corresponding to the right angle of the right-angle bracket 9 is an arc edge, making the frame corners smoother and more aesthetically pleasing. Of course, in some embodiments, the edge of the profile corresponding to the right angle of the right-angle bracket is a straight edge.

[0038] By adopting the above technical solution, the profile only needs to be cut into a plane as needed, and the structure of the right angle bracket 9 can be set to facilitate connection with the profile, avoiding modifications to the profile.

[0039] In this embodiment, the main body 70 of the light strip can be cut to a suitable length and pasted into the light strip mounting groove 4 of the single-sided fabric clip profile. After the main body 70 of the light strip is installed, when two single-sided fabric clip profiles 3 need to be spliced ​​together, right-angle brackets 9 are used to connect the profiles 3. The connection part between the single-sided fabric clip profile 3 and the right-angle bracket 9 can be cut into a plane as needed. After the single-sided fabric clip profiles are assembled into a light box frame 30, the light box canvas 6 is installed, and finally, the wiring terminals are inserted to connect the power.

[0040] Example 2: As Figure 8 As shown, this embodiment differs from Embodiment 1 in that the frame profile used is different. Embodiment 2 discloses a double-sided fabric-insertion profile applied to a double-sided fabric-insertion light box. The light strip assembly and wiring terminals in this embodiment are the same as in Embodiment 1, the difference being that the profile structure is slightly different. The double-sided fabric-insertion profile has symmetrically arranged inverted tooth structures 5 on both sides, and the light strip mounting groove 4 is located at the upper end of the double-sided fabric-insertion profile. As shown in the accompanying drawings, the openings of the two inverted tooth structures 5 are opposite, but perpendicular to the opening direction of the light strip mounting groove 4.

[0041] Example 3: As Figure 9 As shown, this embodiment differs from Embodiment 1 in that the frame profile used is different. Embodiment 3 discloses a single-sided fabric-covered profile applied to a single-sided fabric-covered lightbox. The light strip assembly and wiring terminals in this embodiment are the same as in Embodiment 1, the difference being that the profile structure is slightly different. A canvas fixing bracket 8 is provided on one side of the single-sided fabric-covered profile for hanging the canvas, and a canvas support arm 80 is provided on one side of the canvas fixing bracket 8. The light strip mounting groove 4 is located at the upper end of the single-sided fabric-covered profile and adjacent to the canvas support arm 80. Of course, in some embodiments, the frame profile can also be a double-sided fabric-covered profile, applied to a double-sided fabric-covered lightbox.

[0042] Example 4: Figure 10 As shown, this embodiment differs from Embodiment 1 in that it uses a different frame profile. This invention can also be applied to airport wayfinding sign light boxes, as illustrated in Embodiment 4, which discloses a wayfinding sign light box profile. The light strip assembly and wiring terminals in this embodiment are identical to those in Embodiment 1, with the difference being a slight variation in the profile structure.
