[0010] A further feature of this invention is that: the corner connector is provided with a corner fitting head, the corner connector has a threaded hole, the corner fitting head has a through hole corresponding to the threaded hole, the corner fitting head has a connecting bolt that passes through the through hole and is threaded into the threaded hole, the horizontal fitting part has a first locking hole, the corner fitting head has a first locking head embedded in the first locking hole, the vertical fitting part has a second locking hole, the corner fitting head has a second locking head embedded in the second locking hole, and the corner fitting head has a second right-angled surface at a right angle.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. When assembling the lightbox, insert the end of the three-card lock into the recess of the corner connector. The three three-card locks on the corner connector correspond to two horizontal profiles and one vertical profile, respectively. Then, insert the lock head of the three-card lock into the through hole of the horizontal and vertical profiles. Rotate the eccentric wheel of the three-card lock through the first operating hole. The corner connector can then quickly connect to the two horizontal profiles and one vertical profile through the three three-card locks. When disassembling the lightbox, simply loosen the eccentric wheel of the three-card lock in the first operating hole to unlock the three-card lock, thereby removing the horizontal and vertical profiles. Finally, the lightbox can be quickly assembled and disassembled using the three-card lock.

[0013] 2. By using vertical profiles, including the first profile and the second profile, the vertical profiles can be spliced ​​and connected. At the same time, the three-card lock and the second operating hole can be used to quickly disassemble and assemble the first profile and the second profile, which further facilitates the quick disassembly and assembly of the light box using the three-card lock.

[0014] 3. The first mounting groove for installing light strips is set on the inner side of the horizontal and vertical profiles, which facilitates the lighting inside the light box;

[0015] 4. When the light box needs to be wrapped around a stone pillar, it needs to achieve side lighting. At this time, the second mounting groove set on the inner side of the horizontal profile and inclined to the horizontal profile for installing light strips, as well as the two third mounting grooves set on the inner side of the vertical profile and inclined to the vertical profile for installing light strips, can be used to achieve the side lighting form of the light box on the stone pillar.

[0016] When vertical and horizontal profiles are installed on stone pillars, the horizontal profiles abut against the outer wall of the stone pillar using the horizontal fitting part, while the vertical profiles abut against the edge of the stone pillar using the first right-angle face on the vertical fitting part. This will ultimately help to provide stable support for the horizontal and vertical profiles on the stone pillars.

[0017] 5. Simultaneously, the corner fitting head is provided on the corner connector. The corner fitting head uses the second right angle surface to fit against the edge of the stone column, which is conducive to the stable support of the corner connector on the stone column. The corner fitting head uses the first clip to be embedded in the first clip hole of the horizontal fitting part, and uses the second clip to be embedded in the second clip hole of the vertical fitting part, which is conducive to the stable installation of the corner fitting head between the vertical profile and the horizontal profile.

Detailed Implementation

[0026] The technical solutions in the embodiments will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example 1: A three-card lock light box, as shown in the following example. Figure 1 , Figure 2 This type of three-lock light box includes horizontal profiles 1 located at the top and bottom, vertical profiles 2 located on the periphery, corner connectors 3 located at the corners, three-locks 4 on the corner connectors 3, and multiple light strips 5. The corner connectors 3 have three three-locks 4, each located at a different connection point, used to connect two horizontal profiles 1 and one vertical profile 2. Each corner connector 3 also has an embedding groove for the ends of the three-locks 4 to be inserted. 31. Both the horizontal profile 1 and the vertical profile 2 have through holes 6 for the locking head of the three-card lock 4 to be inserted. The corner connector 3 has a first operating hole 32 on its side that communicates with the insertion groove 31 and allows the eccentric wheel of the three-card lock 4 to pass through. Since the three-card lock 4 is a prior art technology, its specific internal structure will not be described here. At the same time, the inner sides of both the horizontal profile 1 and the vertical profile 2 are integrally provided with a first mounting groove 7 for the installation of the light strip 5. At this time, the light box achieves the internal light-emitting form.

[0028] Reference Figure 1 , Figure 3The vertical profile 2 includes a first profile 21 located on the upper side and a second profile 22 located on the lower side. A three-lock 4 is also provided between the first profile 21 and the second profile 22. The two ends of the three-lock 4 are respectively embedded in the through holes 6 on the upper and lower sides. The upper end of the second profile 22 has a second operating hole 221 that communicates with the through hole 6 and allows the eccentric wheel of the three-lock 4 to pass through. The two light strips 5 on the first profile 21 and the second profile 22 are connected by a spring pin male and female connector.

[0029] Principle: When assembling the light box, the end of the three-card lock 4 is embedded in the embedding groove 31 of the corner connector 3. The three three-card locks 4 on the corner connector 3 correspond to two horizontal profiles 1 and one vertical profile 2 respectively. Then, the lock head of the three-card lock 4 is embedded in the through hole 6 of the horizontal profile 1 and the vertical profile 2. The eccentric wheel of the three-card lock 4 is rotated through the first operating hole 32. Then, the corner connector 3 can quickly connect with the two horizontal profiles 1 and the vertical profile 2 through the three three-card locks 4. When disassembling the light box, simply loosen the eccentric wheel of the three-card lock 4 in the first operating hole 32 to complete the unlocking operation of the three-card lock 4, thereby removing the horizontal profile 1 and the vertical profile 2. Finally, the light box can be quickly assembled and disassembled using the three-card lock 4.

[0030] Example 2: A three-card lock light box, as shown in the following example. Figure 4 , Figure 5 The difference from Embodiment 1 is that the horizontal profile 1 and the vertical profile 2 are mainly used to wrap around the stone column with a rectangular cross-section. The inner side of the horizontal profile 1 is integrally provided with a second mounting groove 11 that is inclined to the horizontal profile 1 and is used for mounting the light strip 5. The inner side of the horizontal profile 1 is also integrally provided with a horizontal fitting part 12 that abuts against the outer wall of the stone column. At the same time, the inner side of the vertical profile 2 is integrally provided with two third mounting grooves 201 that are inclined to the vertical profile 2 and are used for mounting the light strip 5. The inner side of the vertical profile 2 is also integrally provided with a vertical fitting part 202 that abuts against the outer wall of the stone column. The side of the vertical fitting part 202 away from the vertical profile 2 has a first right-angled surface 2021 that is at a right angle.

[0031] Reference Figure 4 , Figure 5 , Figure 6The corner connector 3 is detachably connected to a corner fitting head 8, and the corner connector 3 has a threaded hole 33. The corner fitting head 8 has a through hole 81 corresponding to the threaded hole 33. The corner fitting head 8 is provided with a connecting bolt 82 that passes through the through hole 81 and is threaded into the threaded hole 33. At the same time, the horizontal fitting part 12 has a first locking hole 121, and the corner fitting head 8 is integrally provided with a first locking head 83 embedded in the first locking hole 121. The vertical fitting part 202 has a second locking hole 203, and the corner fitting head 8 is integrally provided with a second locking head 84 embedded in the second locking hole 203. The corner fitting head 8 is also provided with a second right-angled surface 85 at a right angle.

[0032] Principle: When the light box needs to be wrapped around the stone pillar, it needs to achieve side lighting. At this time, the second mounting groove 11, which is inclined to the horizontal profile 1 and is used for the installation of the light strip 5, and the two third mounting grooves 201, which are inclined to the vertical profile 2 and are used for the installation of the light strip 5, can be used to achieve the side lighting form of the light box on the stone pillar.

[0033] When the vertical profile 2 and the horizontal profile 1 are installed on the stone pillar, the horizontal profile 1 abuts against the outer wall of the stone pillar using the horizontal fitting part 12, while the vertical profile 2 is fitted to the edge of the stone pillar using the first right-angle surface 2021 on the vertical fitting part 202. At the same time, the corner fitting head 8 provided on the corner connector 3 is fitted to the edge of the stone pillar using the second right-angle surface 85, which is conducive to the stable support of the corner connector 3 on the stone pillar. The corner fitting head 8 uses the first clip 83 to be embedded in the first clip hole 121 of the horizontal fitting part 12, and uses the second clip 84 to be embedded in the second clip hole 203 of the vertical fitting part 202, which is conducive to the stable installation of the corner fitting head 8 between the vertical profile 2 and the horizontal profile 1, and finally achieves stable wrapping of the stone pillar.
