[0002] At present, with the rapid development of my country's economy, the country has attached more and more importance to education. Good classroom lighting is very necessary. A suitable lighting environment can reduce students' visual fatigue and improve learning efficiency. Blackboards are widely used in teaching activities, and teachers can write teaching content. The application environment of blackboards is very diverse. In some environments with poor lighting, blackboard lights are used to increase the brightness of the blackboard.

[0003] The blackboard lamp needs to be installed with the help of a mounting structure, and the existing blackboard lamp mounting structure usually uses a wall-mounted structure for blackboard lamps for installation.

[0004] After searching, it was found that in a blackboard lamp wall-mounted structure with patent publication number CN219867736U, "two dovetail grooves in opposite directions are used for clamping, and the positioning blocks are used for positioning, and then the dovetail grooves are fixed with bolts. The first dovetail groove wall is bent upward, and the second dovetail groove wall is bent downward. The mounting base can be flexibly changed on the pre-installed track, and the lamp is installed on the mounting base. The uniformity of light can be improved by changing the position of the light source."

[0005] However, the above solution still has certain shortcomings in actual use. In this solution, the wall-mounted connection is achieved by using the interference connection of the bolts between the mounting base and the pre-installed track, and the positioning of the lamp still requires the help of tools, which makes the installation process time-consuming and labor-intensive, thereby affecting the installation efficiency.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model discloses a wall-mounted structure for a blackboard lamp, comprising a mounting bracket 1, a positioning mechanism 2 is movably connected to the inner side of the mounting bracket 1, and a mounting back plate 3 is fixedly connected to the movable end of the positioning mechanism 2; the mounting bracket 1 comprises two contact strips 101, the outer side of the contact strips 101 is connected to the wall through a connecting clip 103, the inner side of the mounting bracket 1 is fixedly connected to a support plate 102, an inner wall of the mounting bracket 1 is hinged with an oblique brace 104, and the other end of the oblique brace 104 is movably plugged with the bottom end of the support plate 102; the positioning mechanism 2 comprises a drive box 201, a cross bar 203 is fixedly installed on the inner wall of the drive box 201, a surface of the cross bar 203 is slidably connected to a collar 204, the front side of the collar 204 is fixedly installed with the mounting back plate 3 through a connecting rod 211, and a gear ring 20 is fixedly installed on the back side of the collar 204 5; The inner wall of the driving box 201 is rotatably connected with a screw rod 206, and the surface of the screw rod 206 is slidably connected with a movable rack 207 through a threaded block, and the movable rack 207 is located just below the gear ring 205, and a gear handle 208 is fixedly installed on the top of the screw rod 206, and the gear handle 208 extends to the top of the driving box 201; by setting a positioning mechanism 2, the ring 204 can be used to drive the mounting back plate 3 to slide along the surface of the cross bar 203, and then the gear handle 208 cooperates with the screw rod 206 to prompt the movable rack 207 to engage with the gear ring 205 on the back side of the ring 204 to limit the relative position of the two mounting back plates 3 and the driving box 201, thereby completing the positioning of the lamp, and the entire lamp installation and positioning process can be completed without the aid of tools, thereby saving time and effort in the installation process, thereby ensuring installation efficiency.

[0023] Specifically, a splicing strip 202 is fixedly installed on the outer side of the driving box 201 , and a notch adapted to the splicing strip 202 is formed on the top of the supporting plate 102 .

[0024] In this embodiment, the notch can be used to facilitate the staff to complete the splicing between the drive box 201 and the support plate 102.

[0025] Specifically, a sliding pin 210 is fixedly connected to the back side of the gear ring 205 , and one end of the sliding pin 210 away from the gear ring 205 is slidably connected to the inner wall of the driving box 201 .

[0026] In this embodiment, the sliding pin 210 can slide along the inner wall of the driving box 201 together with the gear ring 205, thereby improving the movement stability of the gear ring 205.

[0027] Specifically, the top end of the driving box 201 is rotatably connected to a hinged rack 209 via a torsion spring, and the hinged rack 209 is meshed with the gear handle 208 .

[0028] In this embodiment, the automatic resilience of the torsion spring can be used to drive the articulated rack 209 to rebound to the initial position, so that the articulated rack 209 will fit the surface of the gear handle 208, thereby limiting the possibility of the gear handle 208 rotating on its own.

[0029] When in use, find a suitable place to hang the lamp on the wall or blackboard, and then use a method such as a heavy hammer or ink fountain lamp leveling method to make the two contact strips 101 perpendicular to the ground and keep them parallel, and then fix the contact strips 101 at the designated position through the connecting clip 103;

[0030] Then, the driving box 201 and the supporting plate 102 are connected to each other through the splicing strip 202, and then the lamp is connected to the mounting back plate 3, and then the two mounting back plates 3 are dragged to cause the lamp to move in front of the driving box 201, and finally find the position with the best light uniformity;

[0031] At this time, the mounting back plate 3 needs to be positioned, and the staff needs to turn the gear handle 208. Before turning the gear handle, the articulated rack 209 needs to be turned in advance to make the articulated rack 209 gradually move away from the gear handle 208 (the reason for doing this is: since the articulated rack 209 is rotatably connected to the top of the drive box 201 through a torsion spring, the articulated rack 209 has self-rebound under the drive of the torsion spring, causing the articulated rack 209 to always fit on the surface of the gear handle 208, which makes the rotation of the gear handle 208 more difficult. Therefore, only by first moving the articulated rack 209 away from the gear handle 208 can the gear handle 208 move freely).

[0032] After the articulated rack 209 is away from the gear handle 208, the staff starts to rotate the gear handle 208, so that the gear handle 208 drives the screw 206 to rotate, and the rotation of the screw 206 drives the threaded block to move in the axial direction, so that the movement of the threaded block drives the movable rack 207 to adjust the height, so that the movable rack 207 is gradually lifted to the height of the gear ring 205, and the movable rack 207 is meshed with the gear ring 205 at this time (at the same time, it is necessary to loosen the articulated rack 209, and use the automatic resilience of the torsion spring to drive the articulated rack 209 to rebound to the initial position, so that the articulated rack 209 will fit on the surface of the gear handle 208, thereby limiting the possibility of the gear handle 208 rotating on its own);

[0033] Since the movable rack 207 is meshed with the gear ring 205 at this time, the movable rack 207 will limit the movement of the gear ring 205, thereby preventing the ring 204 from sliding on the surface of the cross bar 203, thereby finally completing the positioning process between the installation back plate 3 and the drive box 201.

[0034] In summary, the wall-mounted structure of the blackboard lamp is provided with a positioning mechanism 2, and the ring 204 can be used to drive the mounting back plate 3 to slide along the surface of the cross bar 203, and then the gear turn handle 208 is used to cause the movable rack 207 to engage the gear ring 205 on the back side of the ring 204 through the screw 206, so that the relative positions of the two mounting back plates 3 and the drive box 201 are restricted, thereby completing the positioning of the lamp, and the entire installation and positioning process of the lamp can be completed without the aid of tools, thereby saving time and effort in the installation process, thereby ensuring installation efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
