Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a mounting bracket assembly, a blackboard light equipped with the mounting bracket assembly, and a lighting system equipped with the aforementioned blackboard light. Background Technology

[0002] Most existing blackboard lights are installed using pendant rods. During installation, the spacing of the studs on the blackboard light used for the pendant rods is first measured. Then, holes are drilled in the wall above the ceiling according to this spacing, and the pendant rods are installed. The pendant rods are then connected to the studs on the blackboard light one by one. However, in actual installation, due to construction errors, the spacing between the installed pendant rods and the studs on the blackboard light may deviate, making installation difficult or impossible. This necessitates secondary drilling to adjust the pendant rod spacing, which not only poses a risk to the load-bearing capacity of the pendant rods but also affects the aesthetics of the wall. Secondly, most existing blackboard lights have a fixed lighting angle, and the numerous teaching devices in a classroom can easily obstruct the blackboard light, affecting the lighting effect. Summary of the Invention

[0003] To address the aforementioned problems, the main objective of this invention is to provide a mounting bracket assembly that is easy to install and allows for adjustable blackboard light illumination angle.

[0004] Another objective of this invention is to provide a blackboard light with a mounting bracket assembly.

[0005] Another object of this utility model is to provide a lighting system equipped with the above-mentioned blackboard light.

[0006] To achieve the main objective of this utility model, it provides a mounting bracket assembly, comprising a mounting bracket and a rotating bracket. The mounting bracket has a first connecting portion and two first connecting arms. In a first direction, the first connecting portion is connected between the first ends of the two first connecting arms. The second end of each first connecting arm extends in the first direction away from the other first connecting arm and is formed with a connecting ear. The rotating bracket has a second connecting portion and two second connecting arms. In the first direction, the second connecting portion is connected between the first ends of the two second connecting arms. The second connecting portion is provided with a strip-shaped groove extending in the first direction. The strip-shaped groove penetrates the second connecting portion in the thickness direction. The first connecting arm is rotatably connected to the second connecting arm about a rotation axis parallel to the first direction. A hanging rod is connected to the strip-shaped groove. At least one second connecting arm has a clearance groove at its first end, which penetrates the second connecting arm in the first direction. The strip-shaped groove communicates with the clearance groove.

[0007] As can be seen from the above, the design of the mounting bracket assembly allows for a high tolerance in the assembly of the hanger, rotating bracket, and lamp body when the hanger connects to the slot on the rotating bracket. This ensures a reliable connection between the hanger and the rotating bracket without the need for secondary construction or hanger installation, facilitating on-site construction and effectively guaranteeing the load-bearing strength of the hanger. The rotating bracket and mounting bracket are rotatably connected, and the mounting bracket connects to the blackboard lamp body via connecting ears, making the lighting angle of the blackboard lamp adjustable. This effectively prevents the blackboard lamp's light from being blocked by indoor teaching instruments such as projectors and electronic whiteboards, ensuring that the illuminance meets standards. At the same time, it can reduce the impact of environmental factors such as ceiling height and beams on the blackboard lamp's illumination. In addition, the design of the clearance slot makes it easier and more convenient to insert the screw section of the hanger into the slot.

[0008] A preferred embodiment is that the rotating support has a stop formed at the connection between the strip groove and the clearance groove, and the stop is located in the strip groove and / or the clearance groove.

[0009] A further embodiment is that the stop extends from the first sidewall of the connection to the second sidewall of the connection in the second direction, and the first distance between the extended end of the stop and the second sidewall is less than the second distance between the first sidewall and the second sidewall. Alternatively, there are two stops, and the stops extend from one sidewall of the connection to the other sidewall in the second direction, and the third distance between the extended ends of the two stops is less than the fourth distance between the two sidewalls of the connection. The second direction is perpendicular to the first direction.

[0010] As can be seen from the above, the design can effectively prevent the hanger from detaching from the rotating bracket after installation or during installation, improve the safety of installation, and make the installation and position adjustment of the hanger and the rotating bracket more convenient and easier to operate.

[0011] Another preferred embodiment is that the mounting bracket assembly includes a screw; a first connecting arm has a first through hole that penetrates the first connecting arm in a first direction; a second connecting arm has a second through hole that penetrates the second connecting arm in a first direction; one of the two second through holes is a threaded hole, and the screw passes through the second through hole and the two first through holes and is threadedly connected to the threaded hole; or the mounting bracket assembly further includes a first nut, and the screw passes through the two second through holes and the two first through holes and is threadedly connected to the first nut.

[0012] As can be seen from the above, this design makes the assembly between the mounting bracket and the rotating bracket more convenient, while also ensuring the coaxiality of the rotation between the two first connecting arms and the two second connecting arms.

[0013] A further option is to use a wing screw.

[0014] As can be seen from the above, the design of the screw eliminates the need for external tools when operating and rotating it, making it more convenient and faster to adjust the blackboard light's illumination angle.

[0015] Another further option is that the second connecting arm has a dial on the outer periphery of the second through hole, and the first connecting arm has a scale pointer on the outer periphery of the dial.

[0016] As can be seen from the above, this design makes it easy for users to know the approximate lighting angle of the blackboard light, making it more convenient for users to adjust the lighting angle of the blackboard light.

[0017] Another preferred embodiment is that the second end of the first connecting arm is provided with clearance notches on both sides, and the clearance notches penetrate the first connecting arm in the first direction.

[0018] As can be seen from the above, this design allows the mounting bracket to connect with the slot on the blackboard lamp body, making the assembly between the lamp body and the mounting bracket more convenient and preventing the mounting bracket from detaching from the lamp body during installation, thus improving the safety of the assembly.

[0019] A further option is that a reinforcing rib is formed between the first connecting part and the two first connecting arms; the connecting ear is provided with a connecting hole, which penetrates the connecting ear in the thickness direction.

[0020] As can be seen from the above, reinforcing ribs can improve the structural strength of the mounting bracket.

[0021] To achieve another objective of this utility model, this utility model provides a blackboard lamp, including a lamp body, which also includes the aforementioned mounting bracket assembly, with connecting ears connected to the lamp body.

[0022] As can be seen from the above, blackboard lights equipped with the aforementioned mounting bracket components are more convenient to install and safer; at the same time, the adjustable lighting angle better avoids light obstruction, ensures uniform illumination, and reduces the impact of the installation environment on the blackboard light lighting.

[0023] To achieve another objective of this utility model, this utility model provides a lighting system, including a control terminal, which further includes the aforementioned blackboard light; the control terminal is electrically connected to the blackboard light, and / or the control terminal interacts with the blackboard light.

[0024] As can be seen from the above, the lighting system, by incorporating the aforementioned blackboard lights, makes installation more convenient and safer. Furthermore, the adjustable lighting angle of each blackboard light better prevents light blockage, ensures uniform illumination, and reduces the impact of the installation environment on the blackboard light illumination.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0031] First embodiment of blackboard lamp

[0032] Reference Figure 1 The blackboard light 100 includes a mounting bracket assembly 101 and a light body 102. The mounting bracket assembly 101 is connected between the building (such as a wall 103 at the top of an interior room) and the light body 102 to enable the suspending of the light body 102, and also allows the illumination angle of the light body 102 to be adjusted via the mounting bracket assembly 101. The mounting bracket assembly 101 includes a mounting bracket 1, a rotating bracket 2, and a screw 3.

[0033] Combination Figure 2 and Figure 3 The mounting bracket 1 has a first connecting part 11 and two first connecting arms 12. The two connecting arms are arranged in a roughly mirror-symmetrical manner. In the first direction X, the first connecting part 11 is connected between the first ends of the two first connecting arms 12, so that the first connecting part 11 and the two first connecting arms 12 are roughly inverted U-shape.

[0034] In addition, each first connecting arm 12 has a connecting ear 13 formed at its second end. The first connecting ear 13 extends outward from the other first connecting arm 12 in the first direction X. The connecting ear 13 has a connecting hole 131 that penetrates the connecting ear 13 in the thickness direction. The connecting ear 13 is used to connect to the lamp body 102. During connection, the connecting hole 131 on the connecting ear 13 is fixedly connected to the threaded hole 223 on the lamp body 102 by bolts.

[0035] Preferably, the lamp body 102 is provided with a slot 1021, which extends along the first direction X and penetrates the lamp body 102; and each first connecting arm 12 is provided with a clearance notch 123 at its second end, which penetrates the first connecting arm 12 in the first direction X. This design makes the assembly between the lamp body 102 and the mounting bracket 1 more convenient. During installation, the connecting ear 13 and part of the first connecting arm 12 of the mounting bracket 1 can be slid into the slot 1021 of the lamp body 102 firstly to prevent the mounting bracket 1 from separating from the lamp body 102 during installation. Then, the connecting ear 13 and the lamp body 102 are fixed with bolts, thereby improving the safety and convenience of assembly.

[0036] The rotating bracket 2 has a second connecting portion 21 and two second connecting arms 22, which are arranged in a roughly mirror-symmetrical manner. In the first direction X, the second connecting portion 21 connects between the first ends of the two first connecting arms 12, making the second connecting portion 21 and the two second connecting arms 22 roughly inverted U-shapes. The second connecting portion 21 is provided with a strip groove 211, which extends along the first direction X and penetrates the second connecting portion 21 in the thickness direction. The strip groove 211 is used to connect with the hanger 4. The hanger 4 is connected to the strip groove 211 on the rotating bracket 2, which makes the assembly between the hanger 4 and the rotating bracket 2 and the lamp body 102 have a high fault tolerance rate, thereby ensuring that the hanger 4 can be reliably connected to the rotating bracket 2 without secondary construction of the building or secondary installation of the hanger 4, which brings convenience to on-site construction and effectively guarantees the load-bearing strength of the hanger 4.

[0037] The rotating bracket 2 is rotatably connected to the first connecting arm 12 of the mounting bracket 1 via the second connecting arm 22. The rotation axis of the rotating bracket 2 relative to the mounting bracket 1 is parallel to the first direction X. This rotatable connection between the rotating bracket 2 and the mounting bracket 1 allows for adjustable illumination angle of the blackboard lamp 100, effectively preventing the light from being blocked by indoor teaching equipment such as projectors and electronic whiteboards, ensuring adequate illuminance. Simultaneously, it reduces the impact of environmental factors such as ceiling height and beams on the illumination of the blackboard lamp 100.

[0038] In this embodiment, the mounting bracket 1 and the rotating bracket 2 are connected by a screw 3. Preferably, each first connecting arm 12 is provided with a first through hole 121, which penetrates the first connecting arm 12 in the first direction X, and the first through holes 121 on the two first connecting arms 12 are substantially coaxially arranged; each second connecting arm 22 is provided with a second through hole 222, which penetrates the second connecting arm 22 in the first direction X, and the second through holes 222 on the two second connecting arms 22 are substantially coaxially arranged, wherein one of the two second through holes 222 is a threaded hole 223, and the other can be a round hole or a strip hole. When the second through hole 222 is a strip hole, the strip hole extends along the thickness direction of the second connecting part 21. When mounting bracket 1 and rotating bracket 2 are assembled, the two first connecting arms 12 of mounting bracket 1 are inserted between the two second connecting arms 22 of rotating bracket 2. Then, screw 3 is passed sequentially through the second through hole 222 (non-threaded) and the two first through holes 121, and then threadedly connected to the second through hole 222 of threaded hole 223, thereby connecting mounting bracket 1 and rotating bracket 2 and making the relative angle between them adjustable. This design makes the assembly of mounting bracket 1 and rotating bracket 2 more convenient, and also ensures the coaxiality of rotation between the two first connecting arms 12 and the two second connecting arms 22. Furthermore, screw 3 is preferably a wing screw, so that no external tools are needed when operating and rotating screw 3, making it more convenient and faster to adjust the illumination angle of blackboard light 100 by operating screw 3.

[0039] In addition, the second connecting arm 22 is provided with a scale 224 on the outer periphery of the second through hole 222. Preferably, the scale 224 is located on the outer periphery of the threaded hole 223. Correspondingly, the first connecting arm 12 is provided with a scale pointer 122, and the scale pointer 122 is located on the outer periphery of the scale 224, and the scale pointer 122 points to the scale 224.

[0040] By setting a dial 224 on the second connecting arm 22 and a scale pointer 122 on the first connecting arm 12, the user can roughly know the current illumination angle of the blackboard light 100 through the dial 224 and the scale pointer 122 when adjusting the illumination angle of the blackboard light 100, making it more convenient for the user to adjust the illumination angle of the blackboard light 100. In addition, when the blackboard light 100 has multiple mounting bracket assemblies 101, it is also convenient to keep the adjustment position of each mounting bracket assembly 101 consistent, thereby avoiding the distortion of the blackboard light 100 due to inconsistent adjustment positions of each mounting bracket assembly 101, and ensuring the illumination effect of the blackboard light 100.

[0041] Combination Figure 4The suspension rod 4 has a threaded section 41. In this embodiment, the mounting bracket assembly 101 also includes a second nut 51 and a third nut 52. When assembling the suspension rod 4 with the rotating bracket 2, the second nut 51 is first installed onto the threaded section 41 of the suspension rod 4. Then, the threaded section 41 of the suspension rod 4 passes through the slot 211 of the rotating bracket 2. Next, the third nut 52 is installed onto the threaded section 41 of the suspension rod 4. Subsequently, the second nut 51 and the third nut 52 are adjusted so that the second connecting part 21 is clamped and fixed between the second nut 51 and the third nut 52. This design makes the assembly between the screw 3 and the rotating bracket 2 more convenient, while ensuring the firmness of the connection between the screw 3 and the rotating bracket 2. In addition, this design also makes the horizontal position of the lamp body 102 adjustable to ensure that the lamp body 102 remains horizontal after installation.

[0042] To make it easier and more convenient to insert the screw section 41 of the boom 4 into the slot 211, a clearance groove 221 is provided at the first end of at least one second connecting arm 22 of the rotating bracket 2, and the clearance groove 221 passes through the second connecting arm 22 in the first direction X, so that the slot 211 communicates with the clearance opening. This design allows the screw section 41 of the hanger 4 to pass through the clearance groove 221 on the second connecting part 21 into the strip groove 211 on the second connecting part 21 when assembling the screw section 41 of the hanger 4 with the strip groove 211 of the rotating bracket 2, without having to insert the screw section 41 of the hanger 4 into the strip groove 211 from the top of the second connecting part 21. Therefore, it also allows for simultaneous assembly of two or more hangers 4 with two or more rotating parts. Simultaneously, it avoids the problem that when the screw section 41 of the hanger 4 must be inserted into the strip groove 211 from the top of the second connecting part 21, the tilt of the lamp body 102 can cause the remaining screw sections 41 of the hanger 4 to be difficult to insert into the corresponding strip groove 211. In this embodiment, for example, a clearance groove 221 is provided on one of the second connecting arms 22 of the rotating bracket 2.

[0043] Preferably, the rotating bracket 2 has a stop block 23 formed at the connection between the strip groove 211 and the clearance groove 221. The stop block 23 is located in the strip groove 211 and / or the clearance groove 221. In this embodiment, there are two stop blocks 23. Each stop block 23 extends from one side wall to the other side wall of the connection in the second direction Y. The third distance L3 between the protruding ends of the two stop blocks 23 is less than the fourth distance L4 between the two side walls of the connection. The fourth distance L4 is less than the minimum width of the third nut 52. The second direction Y is perpendicular to the first direction X. This design prevents the screw section 41 of the hanger 4 from coming out of the clearance groove 221 of the second connecting arm 22 whenever the third nut 52 is installed on the screw section 41 of the hanger 4, but the second nut 51 and the third nut 52 do not lock the second connecting part 21 of the rotating bracket 2; or after the second nut 51 and the third nut 52 lock the second connecting part 21 of the rotating bracket 2, it also makes the installation and position adjustment between the hanger 4 and the rotating bracket more convenient and easier to operate.

[0044] In summary, the design of the blackboard light 100 makes installation more convenient and safer; at the same time, the adjustable lighting angle better avoids light obstruction, ensures uniform illumination, and reduces the impact of the installation environment on the blackboard light 100's lighting.

[0045] Second embodiment of blackboard lamp

[0046] Reference Figure 5 The difference between this embodiment and the first embodiment of the blackboard lamp is that, in this embodiment, a reinforcing rib plate 14 is formed between the first connecting part 11 and the two first connecting arms 14. The reinforcing rib plate 14 can improve the structural strength of the mounting bracket 1, thereby enhancing the structural strength of the entire mounting bracket assembly.

[0047] Third embodiment of blackboard lamp

[0048] The difference between this embodiment and the aforementioned blackboard light embodiments lies in the way the stop is set. Specifically, in this embodiment:

[0049] The number of blocks is one. The block extends from the first sidewall of the connection between the strip groove and the clearance groove to the second sidewall of the connection in the second direction, and the first distance between the extended end of the block and the second sidewall is less than the second distance between the first sidewall and the second sidewall.

[0050] Fourth embodiment of blackboard lamp

[0051] The difference between this embodiment and the aforementioned blackboard lamp embodiments lies in the connection structure of the mounting bracket, rotating bracket, and screw. Specifically, in this embodiment:

[0052] The threaded hole design on the second connecting arm of the rotating bracket is eliminated, and a plain hole is used instead. Then, a first nut is added so that when the screw passes through the two first through holes on the mounting bracket and the two second through holes on the rotating bracket, it is threadedly connected to the first nut, thereby allowing the screw to clamp and fix the mounting bracket and the rotating bracket in conjunction with the nut.

[0054] The lighting system includes a control terminal and a blackboard light, wherein the blackboard light is the blackboard light described in any of the first to fifth embodiments of the aforementioned blackboard light; the blackboard light is equipped with a control unit. The control terminal is electrically connected to the control unit of the blackboard light, and / or the control terminal interacts with the control unit. Wherein:

[0055] The control terminal can be a conventional control panel (such as a mechanical switch panel), an intelligent control panel, or a remote control. When the control terminal is a conventional control panel, the control terminal is electrically connected to the control unit.

[0056] When the control terminal is an intelligent control panel or a remote control, the control unit is equipped with a first wireless communication module and the control terminal is equipped with a second wireless communication module; the control terminal and the control unit are electrically connected; and / or the first wireless communication module and the second wireless communication module exchange information.

[0057] Furthermore, the control terminal can also be a smart mobile terminal (such as a mobile phone, tablet computer, smart strapping device, etc.) or an artificial intelligence robot. The lighting system, by incorporating the aforementioned blackboard lights, makes installation more convenient and safer; simultaneously, the adjustable lighting angle of each blackboard light better prevents light obstruction, ensures uniform illumination, and reduces the impact of the installation environment on the blackboard light lighting.
