Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a quick-change mounting base and lighting fixture. Background Technology

[0002] Mounting brackets are key components widely used in linear lighting systems. As an intermediate connector, one end is firmly fixed to the lamp housing, while the other end is designed with specific buckles, hooks, or locking structures to conveniently and securely install the entire lamp onto pre-laid cable trays, guide rails, or various mounting profiles, thereby completing the final positioning and fixing of the lamp.

[0003] Most common mounting brackets are one-piece structures, typically a single metal or plastic component, directly screwed onto a specific location on the lamp housing. The fixing structure for mates with the cable tray is an inseparable unit from the bracket body, resulting in extremely poor compatibility. A mounting bracket of a specific shape and size often only perfectly matches a cable tray with a certain cross-sectional specification. Because different projects and brands use different cable tray standards, when the installation environment changes and the lamp needs to be moved to a different cable tray, the existing mounting bracket becomes incompatible. In this case, tools must be used to completely remove the entire mounting bracket from the lamp, install a new bracket compatible with the new cable tray, and reposition and install it onto the lamp. This process is not only cumbersome and time-consuming, but frequent replacement of mounting brackets and repeated unscrewing of connecting screws can easily lead to stripped screws, wear or damage to the mounting holes of the bracket, thus affecting the overall stability and long-term reliability of the installation structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a quick-change mounting bracket and lighting fixture.

[0005] This application discloses a quick-change mounting bracket comprising: a base component, a locking component, and a mounting component. One end of the base component has a first locking opening, and the other end has a locking hole. One end of the locking component is rotatably mounted on the base component, and the other end of the locking component has a locking portion corresponding to the locking hole. The mounting component includes a mounting piece and a mounting portion. The mounting portion is located on the side of the mounting piece, and one end of the mounting piece extends into or away from the first locking opening. In the locked state, one end of the mounting piece extends into the first locking opening, and the locking portion extends into and locks into the locking hole, thus locking the mounting piece between the first locking opening and the locking portion. In the disassembled state, the locking portion and the locking hole are unlocked, one end of the mounting piece moves away from the first locking opening, and the mounting piece is disassembled and separated from the base component.

[0006] Preferably, the locking component includes a locking part, a pressing part, and a rotating part. One end of the rotating part is rotatably disposed on the base component, and the other end of the rotating part is connected to one end of the pressing part. The locking part is connected to the other end of the pressing part. In the locked state, the pressing part presses against the mounting piece.

[0007] Preferably, the locking part includes a locking piece and a locking protrusion. One end of the locking piece is connected to the other end of the pressing part, and the locking protrusion is located at the other end of the locking piece. In the locked state, the locking piece passes through the locking hole, and the locking protrusion abuts against the bottom wall of the base member.

[0008] Preferably, the pressing part includes a first pressing sheet, a second pressing sheet, and a third pressing sheet, and the rotating part, the first pressing sheet, the second pressing sheet, the third pressing sheet, and the locking part are connected in sequence; in the locked state, the second pressing sheet is pressed against the mounting piece.

[0009] Preferably, the pressing part further includes a positioning protrusion, which is disposed on the second pressing piece. The base piece and the mounting piece are respectively provided with a first positioning hole and a second positioning hole at the position corresponding to the positioning protrusion. In the locked state, the positioning protrusion passes through the second positioning hole and the first positioning hole in sequence and positions the mounting piece.

[0010] Preferably, the base component includes a base plate and fixing plates respectively disposed on both sides of the base plate. A first locking opening is opened on the fixing plate, a locking hole is opened on the base plate, and locking members are respectively rotatably disposed on the two fixing plates. The fixing plates are provided with fixing holes.

[0011] Preferably, the two fixing plates cooperate with the bottom plate to form a wire harness receiving groove.

[0012] Preferably, the mounting component further includes a fixing part, which is located at the end of the mounting piece away from the first locking port, and the fixing part cooperates with the mounting piece to form a second locking port; in the locked state, the base component extends into the second locking port.

[0013] Preferably, the locking part is made of an elastic material.

[0014] This application also provides a luminaire including a quick-change mounting bracket.

[0015] The beneficial effects of this application are as follows: The quick-change mounting bracket of this application has two working states: a locked state and a disassembled state. In the locked state, one end of the mounting piece extends into the first locking hole of the base component, locking one end of the mounting piece. At the same time, the locking part extends into and locks into the locking hole of the base component, thus firmly clamping the mounting piece between the first locking hole and the locking part. At this time, the entire lamp can be stably installed onto the corresponding wire trough through the mounting part. When it is necessary to install the lamp onto a wire trough of a different size, the locking part disengages from the locking hole, releasing the lock and switching to the disassembled state. At this time, the mounting piece is unlocked, and the mounting piece can be removed from the first locking hole of the base component, separating the two. Another mounting component with a mounting part adapted to the new wire trough is then replaced, and one end of its mounting piece is extended into the first locking hole, with the locking part extending into the locking hole to complete the locking. This allows the lamp to be quickly adapted to the new wire trough. This avoids the need to completely remove the entire mounting bracket from the light fixture as in the traditional method. The replacement process is quick and easy, greatly improving the flexibility and efficiency of installation, modification and maintenance, while reducing the risk of component damage due to repeated disassembly and assembly.

[0022] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] Example 1: Reference Figures 1-3 , Figure 1 This is a schematic diagram of the quick-change mounting base in the locked state, as shown in the embodiment. Figure 2 This is a schematic diagram of the quick-change mounting base in the embodiment. Figure 3This is a schematic diagram of the quick-replaceable mounting base in the disassembled state of the embodiment. The quick-replaceable mounting base in this embodiment includes a base component 1, a locking component 2, and a mounting component 3. One end of the base component 1 has a first locking opening 11, and the other end has a locking hole 12. One end of the locking component 2 is rotatably mounted on the base component 1, and the other end of the locking component 2 has a locking part 21 corresponding to the position of the locking hole 12. The mounting component 3 includes a mounting piece 31 and a mounting part 32. The mounting part 32 is located on the side of the mounting piece 31, and one end of the mounting piece 31 extends into or away from the first locking opening 11. In the locked state, one end of the mounting piece 31 extends into the first locking opening 11, and the locking part 21 extends into and locks into the locking hole 12, so that the mounting piece 31 is locked between the first locking opening 11 and the locking part 21. In the disassembled state, the locking part 21 and the locking hole 12 are unlocked, one end of the mounting piece 31 moves away from the first locking opening 11, and the mounting piece 31 is disassembled and separated from the base component 1.

[0024] Refer to together Figure 4 , Figure 4 This is a schematic diagram of a quick-replaceable mounting base in another embodiment. In this embodiment, the quick-replaceable mounting base is used in a linear luminaire as a connecting component between the luminaire housing and the mounting cable tray. Specifically, it is fixedly mounted on the luminaire housing via the base component 1. The mounting part 32 is a snap-fit ​​mounting structure adapted to the target cable tray, allowing the luminaire to be conveniently fixed to the cable tray via the mounting part 32. The quick-replaceable mounting base in this embodiment has two working states: a locked state and a disassembled state. In the locked state, one end of the mounting piece 31 extends into the first locking port 11 of the base component 1, locking one end of the mounting piece 31. Simultaneously, the locking part 21 extends into and locks into the locking hole 12 of the base component 1, thus firmly clamping the mounting piece 31 between the first locking port 11 and the locking part 21. At this time, the entire luminaire can be stably installed onto the corresponding cable tray via the mounting part 32. When the light fixture needs to be installed in a cable tray of a different size, the locking part 21 disengages from the locking hole 12, releasing the lock and switching to the disassembly state. At this time, the mounting piece 31 unlocks and can be removed from the first locking port 11 of the base piece 1, separating the two. Another mounting piece 3 with a mounting part 32 adapted to the new cable tray is then installed, and one end of its mounting piece 31 is inserted into the first locking port 11. The locking part 21 then enters the locking hole 12 to lock, allowing the light fixture to quickly adapt to the new cable tray. This avoids the need to completely remove the entire mounting base from the light fixture as in the traditional method. The replacement process is quick and simple, greatly improving the flexibility and efficiency of installation, modification, and maintenance, while reducing the risk of component damage due to repeated disassembly and assembly. Specifically, there are two mounting parts 32, located on opposite sides of the mounting piece 31.

[0025] Reference Figure 5 , Figure 5The diagram illustrates the structure of the base component in this embodiment. Preferably, the base component 1 includes a base plate 14 and fixing plates 15 respectively located on both sides of the base plate 14. A first locking opening 11 is formed in the fixing plate 15, and a locking hole 12 is formed in the base plate 14. Locking members 2 are rotatably mounted on the two fixing plates 15 respectively. The fixing plates 15 have fixing holes 151. In specific applications, the fixing holes 151 are threaded holes. By tightening screws through the fixing holes 151, the base component 1 can be fixed to the lamp housing. That is, when the lamp needs to be adapted to be installed in a cable tray of other specifications, it is only necessary to release the locking member 2, remove the original mounting member 3 from the base component 1, and replace it with a new mounting member 3 with a compatible mounting part 32. During this process, it is not necessary to tighten the screws fixing the base component 1. The base component 1 always maintains a stable connection with the lamp housing. The replacement process is quick and easy, greatly improving the flexibility and efficiency of installation, modification, and maintenance. Furthermore, the two fixing pieces 15 cooperate with the base piece 14 to form a wire harness receiving groove 152. When the base piece 1 is fixedly installed on the lamp housing, the wire harness can be accommodated in the wire harness receiving groove 152 for wiring, optimizing the layout.

[0026] Reference Figure 6 , Figure 6 The diagram illustrates the structure of the locking component in this embodiment. Preferably, the locking component 2 includes a locking part 21, a pressing part 22, and a rotating part 23. One end of the rotating part 23 is rotatably mounted on the base component 1, and the other end of the rotating part 23 is connected to one end of the pressing part 22. The locking part 21 is connected to the other end of the pressing part 22. In the locked state, the pressing part 22 presses against the mounting piece 31. In specific applications, the two side walls of the rotating part 23 are respectively provided with first rotating holes, and the fixing piece 15 is provided with second rotating holes corresponding to the positions of the first rotating holes. By passing a rotating rivet through the first rotating hole and the second rotating hole, the rotating part 23 can rotate relative to the fixing piece 15. In the locked state, one end of the mounting piece 31 extends into the first locking port 11, and its other end is limited by the locking part 21 extending into the locking hole 12, thereby achieving the limitation and fixation of both ends of the mounting piece 31. Meanwhile, the upper surface of the mounting piece 31 is pressed against the pressing part 22, and the lower bottom surface of the mounting piece 31 contacts the base piece 14, thereby forming a clamping fixation in the vertical direction. In this way, the mounting part 3 is firmly constrained on the base part 1, effectively avoiding shaking during use and significantly improving the stability and reliability of the connection.

[0027] Rereference Figure 6Preferably, the locking part 21 includes a locking piece 211 and a locking protrusion 212. One end of the locking piece 211 is connected to the other end of the pressing part 22, and the locking protrusion 212 is located at the other end of the locking piece 211. In the locked state, the locking piece 211 passes through the locking hole 12, and the locking protrusion 212 abuts against the bottom wall of the base member 1. In specific applications, when the locking piece 211 is pressed down to the locked position, the locking piece 211 passes downward through the locking hole 12 until the locking protrusion 212 at the end of the locking piece 211 passes over the lower surface of the base plate 14. At this time, the lower surface of the base plate 14 forms a block on the locking protrusion 212 in the vertical direction, forming a mechanical self-locking, thereby firmly holding the locking member 2 in the locked state and ensuring that the mounting piece 31 is reliably fixed. Specifically, the locking part 21 is made of an elastic material, specifically spring steel or stainless steel. Since the locking part 21 is made of an elastic material, when the pressing part 22 is pressed down to lock, the locking piece 211 undergoes controllable elastic deformation under the vertical downward pressure and the lateral squeezing action generated when passing through the locking hole 12. This deformation allows the locking protrusion 212 at the end of the locking piece 211 to pass smoothly through the locking hole 12. After the locking protrusion 212 has completely passed through the hole and passed over the lower surface of the base plate 14, the downward pressure applied to the locking member 2 stops, and the locking piece 211 quickly returns to its original shape due to the elasticity of its material. At this time, the locking protrusion 212 after restoring its deformation abuts against the lower surface of the base plate 14, thereby forming a reliable mechanical self-locking structure to prevent the locking piece 211 from accidentally retracting and to ensure a stable locking state.

[0028] Rereference Figure 6 Preferably, the pressing part 22 includes a first pressing piece 221, a second pressing piece 222, and a third pressing piece 223. The rotating part 23, the first pressing piece 221, the second pressing piece 222, the third pressing piece 223, and the locking part 21 are connected in sequence. In the locked state, the second pressing piece 222 is pressed against the mounting piece 31. In specific applications, the first pressing piece 221, the second pressing piece 222, and the third pressing piece 223 are integrally connected. During the locking process, when the rotating part 23 rotates, it drives the first pressing piece 221 to press down, and then the pressure is transmitted through the second pressing piece 222 and applied to the upper surface of the mounting piece 31, thereby forming a clamping force on the mounting piece 31 together with the bottom piece 14.

[0029] Rereference Figure 6Preferably, the pressing part 22 further includes a positioning protrusion 224, which is disposed on the second pressing piece 222. The base piece 1 and the mounting piece 31 are respectively provided with a first positioning hole 13 and a second positioning hole 311 corresponding to the position of the positioning protrusion 224. In the locked state, the positioning protrusion 224 passes through the second positioning hole 311 and the first positioning hole 13 in sequence, and positions the mounting piece 31. The positioning protrusion 224 is provided to achieve auxiliary positioning and automatic correction of the mounting piece 3. When the mounting piece 3 is initially placed, even if one end of the mounting plate 31 is not fully inserted into the preset depth of the first locking hole 11, when the pressing part 22 is pressed down to perform locking, the positioning protrusion 224 on the second pressing piece 222 will first align and extend into the second positioning hole 311. As the pressing part 22 continues to press down, the positioning protrusion 224 penetrates the second positioning hole 311. The interaction between the sidewall of the positioning protrusion 224 and the hole wall generates a horizontal guiding thrust, which automatically pushes the mounting plate 31 to move in the correct direction until it is fully in place, that is, pushes the mounting plate 31 to be fully inserted into the first locking hole 11. The positioning protrusion 224 continues to descend and finally penetrates the first positioning hole 13 on the base piece 1. At this time, the positioning protrusion 224 acts like a positioning pin, not only vertically penetrating the mounting plate 31 and the base piece 1, eliminating the possibility of relative displacement between the two in any direction in the horizontal plane, but also further enhancing the clamping effect of the pressing part 22 and the base piece 14 on the mounting plate 31, improving the rigidity and vibration resistance and anti-loosening ability of the entire locking state.

[0030] Reference Figure 7 , Figure 7 This is a schematic diagram of the mounting component in the embodiment. Preferably, the mounting component 3 further includes a fixing part 33, which is located at the end of the mounting plate 31 away from the first locking port 11, and the fixing part 33 cooperates with the mounting plate 31 to form a second locking port 331. In the locked state, the base component 1 extends into the second locking port 331. In specific applications, the fixing part 33 is a fixing protrusion. When the mounting plate 31 is not locked with the base component 1, there is a second locking port 331 with an opening between the fixing part 33 and the end of the mounting plate 31 away from the first locking port 11, facing the bottom plate 14. During the locking installation process, as one end of the mounting plate 31 gradually extends into the first locking port 11, the opening of the second locking port 331 is simultaneously aligned with and approaches the bottom plate 14. When the mounting plate 31 is fully inserted into the first locking port 11, the bottom plate 14 is also synchronously and precisely inserted and accommodated in the second locking port 331, thus achieving multi-directional locking, thereby improving the overall rigidity and reliability of the installation connection. Specifically, there are two fixing parts 33, which are respectively located on both sides of the mounting plate 31 at the end away from the first locking port 11.

[0031] Example 2: The luminaire in this embodiment includes a luminaire housing, a light source module, and a quick-change mounting base as described in Embodiment 1. The light source module is disposed inside the luminaire housing, and the fixing piece 15 is fixedly installed to the luminaire housing by screws. The mounting part 32 extends out of the luminaire housing and is used to snap and fix with an external wire trough, thereby locking the entire luminaire onto the wire trough.

[0032] In summary, the quick-change mounting bracket in this embodiment has two working states: a locked state and a disassembled state. In the locked state, one end of the mounting piece 31 extends into the first locking port 11 of the base component 1, locking one end of the mounting piece 31. Simultaneously, the locking part 21 extends into and locks into the locking hole 12 of the base component 1, thus firmly clamping the mounting piece 31 between the first locking port 11 and the locking part 21. At this time, the entire lamp can be stably installed onto the corresponding wire trough through the mounting part 32. When it is necessary to install the lamp onto a wire trough of a different size, the locking part 21 disengages from the locking hole 12, releasing the lock and switching to the disassembled state. At this time, the mounting piece 31 unlocks, allowing it to be removed from the first locking port 11 of the base component 1, separating the two. Another mounting component 3 with a mounting part 32 adapted to the new wire trough is then replaced, and one end of its mounting piece 31 is inserted into the first locking port 11, with the locking part 21 extending into the locking hole 12 to complete the locking. This allows the lamp to quickly adapt to the new wire trough. This avoids the need to completely remove the entire mounting bracket from the light fixture as in the traditional method. The replacement process is quick and easy, greatly improving the flexibility and efficiency of installation, modification and maintenance, while reducing the risk of component damage due to repeated disassembly and assembly.
