Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a ceiling-mounted LED lamp. Background Technology

[0002] Ceiling-mounted LED lights are lighting fixtures that use LED chips as the light source and are installed flush against the ceiling surface. Because the top of the light fixture is flat, it appears to be attached to the ceiling, hence the name "ceiling-mounted." Compared to traditional inductive fluorescent ceiling lights with the same brightness, ceiling-mounted LED lights can reduce overall energy consumption by 60%-70%, demonstrating significant energy-saving advantages. They have been widely used in home, office, and public facility lighting.

[0003] Current residential space design exhibits a trend towards functional integration and spatial convergence. Spaces such as open-plan living and dining areas, bedrooms with reading functions, and studies with display and storage areas are becoming increasingly common. These spaces typically accommodate multiple usage scenarios within the same area, requiring lighting equipment to adapt to these scenarios. However, existing ceiling-mounted LED lights mostly have fixed light-emitting surfaces, with the light always pointing vertically downwards. This provides only single-mode floodlighting and cannot flexibly adjust the direction and range of light according to the functional zones within the space, resulting in significant limitations in practical applications. For example, in long, narrow, multi-functional spaces like open-plan living and dining areas, installing a single fixed-emitting ceiling light, limited by its vertical light angle, only allows the light to fall evenly in the center of the space. It cannot concentrate the luminous flux onto a specific functional area according to actual needs, leading to low light utilization when only a single area is used. Therefore, there is an urgent need for ceiling-mounted LED lights adapted to multi-functional spaces. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing ceiling-mounted LED lighting fixtures can only provide single-mode floodlighting in complex spaces such as integrated living and dining rooms, bedrooms with reading needs, and studies with display and storage areas, which cannot provide targeted lighting for the functional areas in use, resulting in low light utilization. Therefore, this invention proposes a new type of ceiling-mounted LED lighting fixture.

[0005] To achieve the above objectives, the present invention employs the following technology: a ceiling-mounted LED light fixture, comprising a housing and two LED light bodies, wherein a top frame is fixed to the top of the housing, and further comprising: The lamp body mounting mechanism includes a horizontal bar, on both sides of which mounting plates are hinged via hinge shafts. Two LED lamp bodies are respectively fixedly mounted on the bottom of the two mounting plates. A torsion spring is provided at the hinge joint between the horizontal bar and the mounting plates. A pair of hinge seats are fixed at one end of the mounting plate. A frame is fixed inside the housing. A connecting unit is provided between each pair of hinge seats. A pressure plate assembly is provided inside the housing. It also includes a position adjustment mechanism, a pressure application mechanism, and a wiring structure; When the pressure plate assembly presses down on the horizontal bar, the two LED lights are arranged in a V-shape to illuminate the areas on both sides respectively; when the pressure plate assembly presses down on one of the connecting units, the two LED lights are tilted to illuminate one side of the area separately.

[0006] As a further description of the above-mentioned ceiling-mounted LED light fixture: the connecting unit includes a rotating shaft rotatably connected between two hinge seats, with insert rods slidably connected to both ends of the rotating shaft, and a spring provided between the insert rods and the rotating shaft, and the axis of the rotating shaft being higher than the axis of the hinge shaft between the crossbar and the mounting plate.

[0007] As a further description of the above-mentioned ceiling-mounted LED light fixture: the pressure plate assembly includes a pressure plate, a magnetic strip is fixed to the inner wall of the pressure plate, a pressure block is fixed to the bottom of the pressure plate, and spring pieces are installed on both sides of the pressure block.

[0008] As a further description of the above-mentioned ceiling-mounted LED light fixture: the position adjustment mechanism includes a motor and a slide rail fixed inside the housing, the slide rail is rotatably connected to a lead screw that is driven by the motor drive shaft, and the bottom of the slide rail is slidably connected to a mounting base that is threadedly connected to the lead screw.

[0009] As a further description of the above-mentioned ceiling-mounted LED light fixture: the pressure mechanism includes an electric push rod fixedly installed on the mounting base, the telescopic end of the electric push rod is fixed with a pressure frame, and a connecting rod structure is hinged between the mounting base and the pressure plate.

[0010] As a further description of the above-mentioned ceiling-mounted LED lamp: the linkage structure is a rhomboid structure composed of four links of equal length connected end to end in sequence. The top and bottom ends of the linkage structure are respectively hinged to the mounting base and the pressure plate. The two links in the linkage structure that are hinged to the mounting base are each fixed with a protruding post inserted into the sliding groove of the pressure frame.

[0011] As a further description of the above-mentioned ceiling-mounted LED light fixture: the bottom of the housing is slidably connected with a locking pin, the rotating shaft is provided with a slot corresponding to the locking pin, and the hinge seat is internally elastically connected with a positioning pin.

[0012] As a further description of the above-mentioned ceiling-mounted LED light fixture: the wiring structure includes a terminal block fixedly installed on a horizontal bar and connected to the LED light body via a wire, and a spiral wire is connected to the top of the terminal block.

[0013] As a further description of the above-mentioned ceiling-mounted LED light fixture: it also includes a stabilizing mechanism, the stabilizing mechanism including a lever rotatably connected to one end of the connecting rod structure, a plate being slidably connected inside the housing, a transmission structure being provided inside the housing, and a magnet and an iron sheet being fixed to the bottom surface of the plate and the top surface of the mounting plate, respectively.

[0014] As a further description of the above-mentioned ceiling-mounted LED lamp: the transmission structure includes a transmission component rotatably connected inside the housing, two support plates are fixed to the outside of the transmission component, and a push plate is fixed to the bottom of the support plate.

[0015] In summary, due to the adoption of the above-mentioned technology in this ceiling-mounted LED light fixture, the beneficial effects of this invention are: 1. This invention uses a pressure plate assembly to press down on the horizontal bar, causing the mounting plate to deflect upward relative to the horizontal bar, which in turn causes the two LED lamp bodies to switch to a V-shape. This significantly increases the lateral coverage of the light, allowing the light emitted by the LED lamp bodies to be projected more evenly to both ends of the long and narrow composite space. This provides illumination for the ends of long and narrow indoor spaces, improving the adaptability to long and narrow composite spaces.

[0016] By pressing down the connecting unit with the pressure plate assembly and adjusting the position with the position adjustment mechanism, the two LED lamp bodies can tilt together to one side, providing targeted and focused lighting for a single functional area in a complex space. This concentrates the light onto the area in use, avoiding ineffective light energy loss caused by general floodlighting and further enhancing the energy-saving benefits of LED lamps.

[0017] 2. Through the coordination of the lamp body installation mechanism, position adjustment mechanism, and pressure application mechanism, the state of the two LED lamp bodies can be further adjusted, so that one LED lamp body tends to be horizontally tilted and the other LED lamp body tends to be vertically tilted. The two LED lamp bodies illuminate the space below and the side space respectively. It is specifically suitable for lighting the first and second floors of some apartment duplexes. There is no need to install lighting fixtures on the upper and lower floors separately, which reduces the number of lighting devices and wiring complexity in duplex spaces, lowers installation costs, and significantly improves the spatial adaptability and light energy utilization of the device in duplex apartment types.

[0018] 3. By moving the latches, the mounting plate and LED lamp body can be disassembled and assembled using the connecting unit and pressure plate assembly. When the LED lamp body experiences light decay or malfunction, the LED lamp body can be removed and replaced individually, while the remaining components can be reused, avoiding resource waste caused by scrapping the entire lamp and effectively reducing the later maintenance and usage costs of the lamp. Furthermore, the disassembly and assembly process requires no tools, and the operation steps are simple and controllable, greatly improving the convenience of lamp repair and replacement and helping to extend the overall lifespan of the lamp.

[0019] 4. The magnetic force of the magnet ensures a tight fit between the iron sheet and the mounting plate and the bottom surface of the housing, enhancing the stability of the mounting plate. Furthermore, when illuminating a single functional area, the pressure mechanism moves the lever, and through the transmission structure and plates, the magnet and iron sheet are automatically misaligned, allowing for smooth angle adjustment of the mounting plate and LED lamp body. This design effectively prevents the mounting plate from vibrating and causing noise or loosening, ensuring the structural stability of the LED lamp body under normal horizontal lighting conditions. It also automatically releases the magnetic constraint during angle adjustment, improving the reliability of the lighting fixture and the user experience. Attached Figure Description

[0022] The following will describe, with reference to the accompanying drawings of the embodiments of the present invention, a ceiling-mounted LED light fixture according to the present invention in a clear and complete manner. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-15 As shown, the present invention provides a ceiling-mounted LED light fixture, including a housing 10, two LED light bodies 12 and a ceiling frame 11 fixed to the ceiling. The housing 10 is sleeved on the bottom of the ceiling frame 11 and is fixed to the ceiling frame 11 by screws.

[0024] Reference Figure 2 , Figure 4 ,and Figure 7 The housing 10 contains a lamp mounting mechanism 20, which includes a horizontal bar 21. Two aluminum alloy mounting plates 22 are hinged to both sides of the horizontal bar 21 via hinge shafts. The two mounting plates 22 are symmetrically arranged about the horizontal bar 21. Two LED lamp bodies 12 are fixed to the bottom of the two mounting plates 22 with screws. A torsion spring 23 is provided at the hinge point between the horizontal bar 21 and the mounting plates 22. The mounting plates 22 are T-shaped, with their bottom sides abutting against the adjacent sides of the two mounting plates 22 to prevent them from deflecting downwards. The torsion spring 23 is always in a tightened state, ensuring close contact between the mounting plates 22 and the horizontal bar 21 and guaranteeing stability during movement. A pair of hinge seats 24 are fixed to the opposite ends of the two mounting plates 22. Two pairs of frames 25 are fixed inside the housing 10, with each pair of hinge seats 24 located between a pair of frames 25.

[0025] Reference Figure 8 and Figure 9 Each pair of hinge seats 24 is provided with a connecting unit 26. The connecting unit 26 includes a rotating shaft 261 rotatably connected between the two hinge seats 24. Both ends of the rotating shaft 261 are slidably connected with insert rods 263. A spring 262 is provided between the insert rods 263 and the rotating shaft 261. One end of the insert rod 263 passes through the hinge seat 24 and extends into the groove of the frame 25. The width of the groove of the frame 25 is equal to the diameter of the insert rod 263, and the insert rod 263 can rotate and slide inside the groove. With the support of the frame 25 for the insert rod 263, the hinge seat 24, the mounting plate 22, the crossbar 21, and the LED lamp body 12 can be stably installed on the bottom of the housing 10.

[0026] Reference Figure 6 The device is equipped with a pressure plate assembly 27, which includes a pressure plate 271. A magnetic strip 272 is fixed to the inner wall of the pressure plate 271. The inner diameter of the magnetic strip 272 is equal to the diameter of the rotating shaft 261, and it can be tightly connected to the iron rotating shaft 261 by magnetic force. A pressure block 273 is fixed to the bottom of the pressure plate 271. One side of the bottom of the pressure block 273 is inclined. Square holes for the pressure block 273 to pass through are opened on both the rotating shaft 261 and the insertion rod 263.

[0027] The top of the horizontal bar 21 is fixed with a limiting strip that mates with the bottom groove of the pressure plate 271 and a buckle that mates with the pressure block 273, which are used to position the horizontal bar 21 when the pressure plate 271 presses down.

[0028] Reference Figure 3 and Figure 6 It is also provided with a position adjustment mechanism 30 for adjusting the position of the pressure plate assembly 27 laterally and a pressure application mechanism 40 for driving the pressure plate assembly 27 to move longitudinally.

[0029] When it is necessary to enhance the lighting intensity at both ends of a narrow, complex space, the pressure plate 271 is vertically aligned with the horizontal bar 21. Then, the pressure mechanism 40 drives the pressure plate 271 and the pressure block 273 to descend, so that the pressure plate 271 contacts the limiting strip and the pressure block 273 is embedded in the buckle. Then, the pressure plate 271 continues to descend, pressing down the horizontal bar 21. The downward movement of the horizontal bar 21 causes the two mounting plates 22 to deflect upward relative to the horizontal bar 21, further compressing the torsion spring 23. At the same time, the other ends of the two mounting plates 22 drive the rotating shaft 261 and the insertion rod 263 to move through the hinge seat 24, so that the insertion rod 263 slides in the groove of the frame 25. The LED lamp body 12 moves with the mounting plate 22, transforming into... Figure 13 The state shown.

[0030] like Figure 13In the shown state, the two LED lamp bodies 12 are arranged in a V-shape. Compared with facing downwards, this state can significantly increase the lateral coverage of the light, so that the light emitted by the LED lamp bodies 12 can be projected more evenly to both ends of the narrow and long composite space. For lighting the narrow and long indoor space near the two ends, this invention improves the space adaptability and practical value through this design.

[0031] During reset, the pressure plate assembly 27 is moved upward by the pressure mechanism 40. During this process, the pressure plate 271 positions the limit bar and the horizontal bar 21, so that the horizontal bar 21 is always in the center position at the bottom of the housing 10. The torsion spring 23 releases its elastic force to drive the mounting plate 22 to deflect downward around the horizontal bar 21, so that the horizontal bar 21 moves upward until the horizontal bar 21 and the mounting plate 22 return to horizontal.

[0032] When only one independent functional area of ​​the composite space is used, the position adjustment mechanism 30 drives the pressure mechanism 40 and the pressure plate assembly 27 to move laterally, so that the pressure plate assembly 27 is vertically aligned with the connecting unit 26. Then, the pressure mechanism 40 drives the pressure plate 271 and the pressure block 273 to descend, so that the pressure plate 271 contacts the rotating shaft 261. The magnetic strip 272 tightly attracts the rotating shaft 261 through magnetic force. After the pressure block 273 is inserted into the square hole of the rotating shaft 261, the inclined surface pushes the top edge of the square hole of the insertion rod 263, so that the insertion rod 263 moves axially to be pulled out from the slide groove of the frame 25 and retracted into the interior of the rotating shaft 261. The connecting unit 26 is no longer connected to the hinge seat 24 and the frame 25. Then, the pressure plate assembly 27 continues to move downward via the pressure applying mechanism 40. Simultaneously, the pressure plate assembly 27 moves laterally via the position adjustment mechanism 30. The connecting unit 26 moves along with the pressure plate assembly 27, causing the hinge seat 24 connected to it to move. By controlling the position of the hinge seat 24, the two mounting plates 22 gradually tilt, causing the LED lamp body 12 to switch to the desired position. Figure 14 As shown, during this process, the rotating shaft 261 and the hinge seat 24 rotate relative to each other, and the square hole of the rotating shaft 261 always faces upward.

[0033] like Figure 14 In the state shown, the two LED lamp bodies 12 are located in the same plane and tilt together to illuminate one side, which can provide targeted and focused lighting for a single functional area in a complex space, concentrate the light onto the area of ​​use, avoid the ineffective light energy loss caused by general floodlighting, and further enhance the energy-saving benefits of LED lamps.

[0034] Furthermore, the axis of the rotating shaft 261 is higher than the axis of the hinge shaft between the crossbar 21 and the mounting plate 22, based on... Figure 14In this state, the position adjustment mechanism 30 continues to move the pressure plate assembly 27 and the connecting unit 26 towards the mounting plate 22, while the pressure application mechanism 40 moves the pressure plate assembly 27 and the connecting unit 26 upward. During this process, the connecting unit 26 installed at the end of the two mounting plates 22 away from the pressure plate assembly 27 is supported and limited by the sliding groove of the frame 25, while the end closer to the pressure plate assembly 27 is squeezed by an upward force, causing the two mounting plates 22 to overcome the elastic force of the torsion spring 23 and deflect around the crossbar 21, causing the LED lamp body 12 to switch to the position shown in the image. Figure 15 As shown in the diagram. Since the torsion springs 23 between the two mounting plates 22 and the crossbar 21 are identical, the two mounting plates 22 remain symmetrical with respect to the crossbar 21 throughout the process. This design allows the two LED lamp bodies 12 to illuminate the lower and side spaces respectively, making it specifically suitable for lighting the first and second floors of some duplex apartments. It eliminates the need for separate lighting fixtures on the upper and lower floors, reducing the number of lighting devices and wiring complexity in duplex spaces, lowering installation costs, and significantly improving the spatial adaptability and light energy utilization of ceiling lights in duplex apartments.

[0035] Furthermore, in this state, the tilt angle of the two LED lamp bodies 12 can be further adjusted, so that one LED lamp body 12 tends to tilt horizontally and the other LED lamp body 12 tends to tilt vertically. The deflection angle of the two LED lamp bodies 12 can be flexibly adjusted according to the difference in floor height and functional zoning of the duplex space, which can further improve the lighting effect.

[0036] Reference Figure 3 and Figure 11 A wiring mechanism is provided between the LED lamp body 12 and the top frame 11. The wiring structure includes a terminal block 61 fixedly installed on the crossbar 21 and connected to the LED lamp body 12 via a wire. The wire is provided with sufficient length to allow relative deflection between the LED lamp body 12 and the crossbar 21. A spiral wire 62 is connected to the top of the terminal block 61, and the top of the spiral wire 62 is connected to the building wiring. The spiral wire 62 is elastic and can adapt to changes in the position of the crossbar 21 by stretching and contracting, preventing tangling or loosening.

[0037] Reference Figure 6Both sides of the pressure block 273 are equipped with spring pieces 274. The inner wall of the square hole of the rotating shaft 261 and the inner wall of the buckle are both provided with grooves. During the process of the pressure block 273 being inserted into the square hole and the buckle, the spring pieces 274 deform and shrink. After the spring pieces 274 are aligned with the grooves, they deform and re-embed into the grooves. This is used to enhance the stability of the connection between the rotating shaft 261 and the pressure block 273 and to prevent the pressure plate assembly 27 from disengaging from the connecting unit 26 during the angle adjustment of the LED lamp body 12. During the process of the pressure plate assembly 27 driving the connecting unit 26 to move upward and reset, after the mounting plate 22 contacts the bottom of the housing 10, the pressure plate 271 continues to move upward, which can drive the pressure block 273 to squeeze the spring pieces 274. After the spring pieces 274 deform and shrink, they are released from the square hole along with the pressure block 273.

[0038] Reference Figure 3 The position adjustment mechanism 30 includes a motor 31 and a slide rail 32 fixed inside the housing 10. A lead screw 33, which is rotatably connected to the drive shaft of the motor 31, is rotatably connected inside the slide rail 32. A mounting seat 34, threadedly connected to the lead screw 33, is slidably connected to the bottom of the slide rail 32. When the motor 31 drives the lead screw 33 to rotate, the mounting seat 34 slides laterally at the bottom of the slide rail 32 via the thread, thereby adjusting the position of the pressure plate assembly 27.

[0039] Reference Figure 6 The pressure applying mechanism 40 includes an electric push rod 41 fixedly installed on the mounting base 34. The telescopic end of the electric push rod 41 is fixed with a pressure frame 42. A connecting rod structure 43 is hinged between the mounting base 34 and the pressure plate 271. The connecting rod structure 43 is a rhomboid structure composed of four connecting rods of equal length connected end to end in sequence. The top and bottom ends of the connecting rod structure 43 are respectively hinged to the mounting base 34 and the pressure plate 271. The bottom end of the connecting rod structure 43 is interference-fitted with the hinge of the pressure plate 271. When the connecting rod structure 43 lifts the pressure plate 271, it maintains the horizontal state of the pressure plate 271 through friction to prevent the pressure plate 271 from shaking. The two connecting rods in the connecting rod structure 43 that are hinged to the mounting base 34 are each fixed with a protruding post 44 that is inserted into the groove of the pressure frame 42.

[0040] When the control mounting base 34 moves the pressure frame 42 downward, the pressure frame 42 presses down on the protrusion 44, causing the two connecting rods in the connecting rod structure 43 that are hinged to the mounting base 34 to deflect downward, thereby causing the remaining two connecting rods to move downward and deflect upward relative to the pressure plate 271, so that the pressure plate 271 moves vertically downward; conversely, when the control mounting base 34 moves the pressure frame 42 upward, it pulls the protrusion 44 so that the two connecting rods above deflect and reset, causing the remaining connecting rods and the pressure plate 271 to reset.

[0041] The pressure mechanism 40 allows the pressure plate assembly 27 to have a longer displacement stroke in the vertical direction without occupying more longitudinal space, thereby increasing the tilt range of the LED lamp body 12, solving the problem of lamp space occupation, and improving the aesthetics of the lamp.

[0042] Reference Figure 12 Based on the above design, in order to facilitate the replacement of the LED lamp body 12 and allow the remaining components to be reused, thus saving the operating cost of the ceiling light, a locking pin 51 is slidably connected to the bottom of the housing 10, and a slot corresponding to the locking pin 51 is provided on the rotating shaft 261. When switching the LED lamp body 12 to... Figure 14 Before the indicated state, manually move the locking pin 51 into the slot of the rotating shaft 261 away from the pressure plate assembly 27, and then adjust the LED lamp body 12 as shown. Figure 14 In the state shown, during the adjustment process, the rotating shaft 261, locked by the locking pin 51, will not rotate, and the square hole opening of the rotating shaft 261 will always be facing upwards. Then, manually limit the deflection of the LED lamp body 12 and control the pressure mechanism 40 to drive the pressure plate assembly 27 upwards, so that the pressure plate assembly 27 is separated from the rotating shaft 261. Then, the locking pin 51 is pushed back to its original position, and the lateral position of the pressure plate assembly 27 is adjusted by the position adjustment mechanism 30 so that the pressure plate assembly 27 is vertically aligned with another rotating shaft 261. The pressure mechanism 40 drives the pressure plate assembly 27 downwards, so that the pressure block 273 is inserted into the square hole of the rotating shaft 261. The insertion rod 263 is pushed by the inclined plane, so that the insertion rod 263 is pulled out from the frame 25, and the horizontal bar 21, mounting plate 22, hinge seat 24 and connecting unit 26 can be removed from the bottom of the housing 10 together.

[0043] With the above design, when the LED lamp body 12 experiences light decay or malfunction, the LED lamp body 12 can be removed and replaced separately, while the remaining components can be reused. This avoids the waste of resources caused by scrapping the entire lamp and effectively reduces the later maintenance and usage costs of the lamp. At the same time, the disassembly and assembly process does not require tools, and the operation steps are simple and controllable, greatly improving the convenience of lamp repair and replacement and helping to extend the overall service life of the lamp.

[0044] Reference Figure 9 The hinge seat 24 has an internal elastic connection with a positioning pin 52, which is embedded in a positioning groove on one side of the rotating shaft 261, for adjusting the LED lamp body 12 to such a position. Figure 13 During the process shown, avoid rotating the shaft 261 to prevent the square hole of the LED body 12 from being misaligned after reset.

[0045] Reference Figure 3 , Figure 4 and Figure 5To improve the stability of the device, a stabilizing mechanism 70 is provided. The stabilizing mechanism 70 includes a lever 71 rotatably connected to one end of the connecting rod structure 43. A plate 73 is slidably connected inside the housing 10. A transmission structure 72 is provided inside the housing 10. A magnet 74 and an iron sheet 75 are respectively fixed to the bottom surface of the plate 73 and the top surface of the mounting plate 22. When the pressure plate assembly 27 is in the center position inside the housing 10, the magnet 74 and the iron sheet 75 are aligned. The magnet 74 attracts the frame 25 through magnetic attraction, which can make the mounting plate 22 fit tightly against the bottom surface of the housing 10, thereby locking the crossbar 21 and preventing the crossbar 21 from moving down against the elastic force of the torsion spring 23 when it is vibrated, causing the mounting plate 22 to vibrate up and down.

[0046] The transmission structure 72 includes a transmission component 721 rotatably connected inside the housing 10. Two support plates 722 are fixed on the outer side of the transmission component 721, and a push plate 723 for pushing the plate 73 is fixed on the bottom of the support plate 722.

[0047] When the linkage structure 43 is at its longest lateral width, the pressure plate assembly 27 and the pressure applying mechanism 40 are located in the middle of the housing 10. When the position adjustment mechanism 30 drives the pressure applying mechanism 40 to move laterally from the middle of the housing 10 to one side, the lever 71 will contact one of the support plates 722 and push the support plate 722 to drive the transmission component 721 to rotate. The other support plate 722 will deflect with the transmission component 721 to the position before the previous support plate 722 was pushed. The rotation of the transmission component 721 will drive the push plate 723 to push the plate 73, causing the plate 73 to drive the magnet 74 to slide. The magnet 74 will be misaligned with the iron piece 75, so that the iron piece 75 is no longer subject to magnetic attraction, so that the mounting plate 22 can be switched to the position as shown. Figure 14 The state shown.

[0048] like Figure 14 In the state shown, the linkage structure 43 is in a longitudinally extended state, and the lever 71 is no longer vertically aligned with the support plate 722. Therefore, the pressure frame 42 will no longer drive the lever 71 to push the support plate 722 during the lateral movement.

[0049] When the position adjustment mechanism 30 drives the pressure application mechanism 40 to reset from one side of the housing 10 to the middle of the housing 10, the paddle 71 pushes another support plate 722, so that the magnet 74 is re-aligned with the iron plate 75. The magnetic attraction of the magnet 74 increases the stability of the connection between the mounting plate 22 and the housing 10.

[0050] When the pressure plate assembly 27 is in the center position inside the housing 10, the magnetic attraction force of the magnet 74 provides an upward pulling force to the iron sheet 75 and the mounting plate 22, causing the pressure plate 271 and the pressure block 273 to move downward. When the pressure block 273 is inserted into the buckle, the buckle has sufficient bearing capacity to squeeze the spring 274, causing the spring 274 to be embedded in the groove, so that the pressure plate 271 and the pressure block 273 can move upward and drive the crossbar 21 to reset.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the present invention's technology and inventive concept, should be covered within the scope of protection of the present invention.
