Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting structure that can be installed on a square tube ceiling. Background Technology

[0002] In recent years, square tube ceilings have become a preferred roofing solution for many offices and entertainment venues due to their advantages such as open views, good ventilation, durability, and easy maintenance. As the application of square tube ceilings has become more widespread, the variety of accessories available for them has also increased, including linear lights installed on square tube ceilings.

[0003] Existing linear lights installed in square tube ceilings consist of a light body with a screw on its upper side and a rotatable mounting plate near the top of the screw. Installation typically requires two technicians working together: one holds the light body from below, while the other reaches above the square tubes or climbs onto the ceiling to adjust the angle of the mounting plate. This allows the plate to pass between two square tubes and ultimately hang on two adjacent tubes. Then, tools are used to carefully adjust the relative height between the light body and the tubes. This linear light installation process is complex and requires significant manpower. Furthermore, in reality, some square tube ceilings have very narrow spacing between the tubes, making it difficult for technicians to reach in for adjustments. In some cases, the distance between the square tube ceiling and the roof is too small to easily hang the mounting plate on the tubes. In these situations, the installation of the linear lights becomes even more difficult. Utility Model Content

[0004] The main purpose of this utility model is to propose a linear light structure that can be installed on a square tube ceiling, aiming to solve the technical problem that installing linear lights on a square tube ceiling is too troublesome in the prior art.

[0005] To achieve the above objectives, this utility model proposes a lighting fixture structure that can be installed on a square tube ceiling, including a lamp body. The lamp body is provided with at least two mounting components, which are respectively located near opposite side walls of the lamp body. Each mounting component includes a mounting rod, a connecting rod, and a mounting block. The mounting rod is at least partially located on the upper side of the lamp body. The mounting block is located on the upper side of the mounting rod via the connecting rod and is spaced apart from the lamp body. The connecting rod is provided with an elastic structure. During installation, the elastic structure can push the mounting block out, so that the square tube of the ceiling is located between the mounting block and the lamp body.

[0006] The beneficial effects of this utility model are as follows: In this utility model, when installing the lamp structure onto the square tube ceiling, the mounting blocks located on both sides of the lamp body are first guided into the space between adjacent ceiling square tubes. Then, the lamp body is pushed upwards. When the mounting blocks reach the upper side of the corresponding ceiling square tube, the elastic structure pushes the mounting blocks out, so that the corresponding ceiling square tube is located between the mounting blocks and the lamp body. During this installation process, technicians do not need to reach above the square tube ceiling, nor do they need to climb above it, which helps reduce the installation difficulty of the lamp structure, simplifies the installation process, and improves installation efficiency.

[0007] Preferably, the mounting rod has a second through hole, the connecting rod passes through the second through hole and can move along the second through hole, one end of the connecting rod has a limiting block and the other end has a mounting block; the elastic structure includes a tension spring, which is sleeved on the connecting rod, one end of the tension spring is connected to the limiting block and the other end is connected to the mounting rod, or the elastic structure includes a compression spring, which is sleeved on the connecting rod, one end of the compression spring is connected to the mounting rod and the other end is connected to the mounting block.

[0008] Preferably, the mounting block is provided with a guide slope. The mounting block is located near one side wall of the lamp body. The guide slope on the mounting block is inclined from top to bottom in the direction from near to away from the other side wall of the lamp body. During installation, the guide slope can guide the mounting block to move between two adjacent ceiling square tubes, which helps to further simplify the installation process of the lamp structure and improve the installation efficiency of the lamp structure on the square tube ceiling.

[0009] Preferably, the mounting assembly further includes a gear structure and a locking structure for fixing the gear structure. The gear structure is rotatably connected to the interior of the lamp body. The lamp body includes an upper side plate and a lower side plate. The upper side plate has a first through hole.

The lower side plate of the lamp body also has a clearance groove. The gear protrudes from the lower side plate of the lamp body through the clearance groove. The locking structure is located on the lamp body and corresponds to the position of the gear structure, which reduces the installation difficulty and makes the installation process smoother.

[0010] Preferably, the locking structure includes a locking cylinder, a locking spring, a locking element, and a locking groove on the gear structure. The locking cylinder is located on the lamp body and beside the gear structure, with its opening facing the gear structure. A locking spring is provided inside the locking cylinder, with one end connected to the bottom of the locking cylinder and the other end provided with a locking element. The locking groove is located on the side wall of the gear structure near the locking cylinder, and the locking element is matched with the locking groove. During installation, when the gear structure rotates to the point where the locking groove is directly opposite the opening of the locking cylinder, the locking spring pushes the locking element into the locking groove to lock the gear structure.

[0013] Preferably, the locking structure further includes a locking rod that can drive the locking cylinder to rotate. The locking rod is fixed relative to the lamp body in the height direction. One end of the locking rod is connected to the locking cylinder, and the other end passes through the lower side plate of the lamp body. A handle is provided at the end of the locking rod that passes through the lower side wall of the lamp body. The locking rod is used to make the locking part leave the position corresponding to the locking groove, which is beneficial to improving the efficiency of inspection, maintenance or disassembly of the lamp structure.

[0038] like Figures 1 to 18 As shown, a lighting fixture structure that can be installed on a square tube ceiling includes a lamp body 1. The lamp body 1 is provided with at least two mounting components 2, which are respectively located near opposite side walls of the lamp body 1. The mounting components 2 include a mounting rod 211, a connecting rod 22, and a mounting block 23. The mounting rod 211 is at least partially located on the upper side of the lamp body 1. The mounting block 23 is located on the upper side of the mounting rod 211 via the connecting rod 22 and is spaced apart from the lamp body 1. The connecting rod 22 is provided with an elastic structure 24. During installation, the elastic structure 24 can push out the mounting block 23, so that the ceiling square tube 10 of the square tube ceiling is located between the mounting block 23 and the lamp body 1.

[0039] In this embodiment, when installing the lighting fixture structure onto the square tube ceiling, the mounting blocks 23 located on both sides of the lamp body 1 are first guided into the space between adjacent ceiling square tubes 10. Then, the lamp body 1 is pushed upwards. When the mounting blocks 23 reach the upper side of the corresponding ceiling square tube 10, the elastic structure 24 pushes the mounting blocks 23 out, so that the corresponding ceiling square tube 10 is located between the mounting blocks 23 and the lamp body 1. During this installation process, technicians do not need to reach above the square tube ceiling, nor do they need to climb above it, which helps to reduce the installation difficulty of the lighting fixture structure, simplify the installation process, and improve installation efficiency.

[0040] In this embodiment, a linear light structure is used as an example. Of course, the light fixture structure described in this embodiment can also adopt other light fixture forms, as long as the structure of this embodiment can be applied and installed on a square tube ceiling.

[0041] In this embodiment, the lamp body is provided with four mounting components 2, which are arranged in a matrix.

[0042] In some specific embodiments, reference is made to Figures 1 to 4The mounting rod 211 has a second through hole 2111, and the connecting rod 22 passes through the second through hole 2111 and can move along the second through hole 2111. One end of the connecting rod 22 has a limiting block 221, and the other end has a mounting block 23. The elastic structure 24 includes a tension spring 241, which is sleeved on the connecting rod 22. One end of the tension spring 241 is connected to the limiting block 221, and the other end is connected to the mounting rod 211. Alternatively, the elastic structure 24 includes a compression spring, which is sleeved on the connecting rod 22. One end of the compression spring is connected to the mounting rod 211, and the other end is connected to the mounting block 23.

[0043] Specifically, the lamp body 1 of the linear light structure has a left side wall and a right side wall. In this embodiment, the second through hole 2111 extends in the left-right direction. In the mounting assembly 2 near the left side wall, the limiting block 221 is located at the right end of the connecting rod 22, and the mounting block 23 is located at the left end of the connecting rod 22; correspondingly, in the mounting assembly 2 near the right side wall, the limiting block 221 is located at the left end of the connecting rod 22, and the mounting block 23 is located at the right end of the connecting rod 22.

[0044] When the elastic structure 24 includes a tension spring 241, the tension spring 241 is sleeved on the connecting rod 22 and located between the limiting block 221 and the mounting rod 211. Taking the mounting component 2 near the left side wall as an example, during installation, the mounting block 23 needs to be moved to the right first, so that the mounting block 23 is directly below the gap between two adjacent ceiling square tubes 10. At this time, the tension spring 241 is in a tensioned and stored state. Then, the linear light structure is moved upward, moving the mounting block 23 into the gap between two adjacent ceiling square tubes 10. During this process, the tension spring 241 will cause the mounting block 23 to squeeze one of the two ceiling square tubes 10 on the left. However, at this time, the tension spring 241 is still in a tensioned and stored state. Finally, when the mounting block 23 reaches the upper side of the gap between two adjacent ceiling square tubes 10, the tension spring 241 causes the mounting block 23 to move to the upper side of the left ceiling square tube 10, so that the left ceiling square tube 10 is located between the light body 1 and the left mounting block 23. At this time, the tension spring 241 may be in a tensioned and stored state or in a normal state.

[0045] Correspondingly, the right-side mounting component 2 is used in the same way as the left-side mounting component 2. The right-side ceiling square tube 10 is located between the lamp body 1 and the right-side mounting block 23. At this time, the linear light structure can be suspended on the square tube ceiling by relying on the mounting blocks 23 on both the left and right sides.

[0046] When the elastic structure 24 includes a compression spring, the compression spring sleeve is disposed on the connecting rod 22 and located between the mounting block 23 and the mounting rod 211. Taking the mounting component 2 near the left side wall as an example, during installation, the mounting block 23 needs to be moved to the right first, so that the mounting block 23 is located directly below the gap between two adjacent ceiling square tubes 10. At this time, the compression spring is in a compressed and stored state. Then, the linear light structure is moved upward, moving the mounting block 23 into the gap between two adjacent ceiling square tubes 10. During this process, the compression spring will cause the mounting block 23 to squeeze one of the two ceiling square tubes 10 on the left, but at this time the compression spring is still in a compressed and stored state. Finally, when the mounting block 23 reaches the upper side of the gap between two adjacent ceiling square tubes 10, the compression spring causes the mounting block 23 to move to the upper side of the left ceiling square tube 10, so that the left ceiling square tube 10 is located between the light body 1 and the left mounting block 23. At this time, the compression spring may be in a compressed and stored state or in a normal state.

[0047] In some specific embodiments, reference is made to Figure 3 , Figure 14 and Figure 15 The mounting block 23 is provided with a guide slope 231. The mounting block 23 is located near one side wall of the lamp body 1. The guide slope 231 on it slopes from top to bottom in the direction from near to away from the other side wall of the lamp body 1. During installation, the guide slope 231 can guide the mounting block 23 to move between two adjacent ceiling square tubes 10.

[0048] The mounting block 23 located near the right side of the lamp body 1 has a guide slope 231 that slopes from top to bottom in the direction from left to right; the mounting block 23 located near the left side of the lamp body 1 has a guide slope 231 that slopes from top to bottom in the direction from right to left.

[0049] Specifically, the leftmost of two adjacent ceiling square tubes 10 is called the first ceiling square tube 10, and the rightmost one is called the second ceiling square tube 10. When unaffected by external forces, the distance between the two mounting blocks 23 on the lamp body 1 in the width direction of the lamp body 1 is slightly smaller than the distance between the first and second ceiling square tubes 10. During installation, the linear light structure is first moved below the two ceiling square tubes 10, so that the guide slope 231 on the left mounting block 23 is directly below the lower right edge of the first ceiling square tube 10, and the guide slope 231 on the right mounting block 23 is directly below the lower left edge of the second ceiling square tube 10. Thus, when the linear light structure is moved upward, the mounting block 23 on the left side smoothly enters the gap between two adjacent ceiling square tubes 10 under the mutual squeezing action of its guide slope 231 and the lower right edge of the first ceiling square tube 10. Similarly, the mounting block 23 on the right side can also smoothly enter the gap between two adjacent ceiling square tubes 10 under the mutual squeezing action of its guide slope 231 and the lower left edge of the second ceiling square tube 10.

[0050] The guide slope 231 on the mounting block 23 allows the mounting block 23 to quickly and smoothly enter the gap between two adjacent ceiling square tubes 10 during installation, which helps to further simplify the installation process of the lighting structure and improve the installation efficiency of the lighting structure on the square tube ceiling.

[0051] In some specific embodiments, reference is made to Figures 2 to 5 as well as Figure 9 The mounting assembly 2 also includes a gear structure 25 and a locking structure 3 for fixing the gear structure 25. The gear structure 25 is rotatably connected to the interior of the lamp body 1. The lamp body 1 includes an upper side plate 11 and a lower side plate 12. The upper side plate 11 is provided with a first through hole 111. The mounting rod 211 passes through the first through hole 111 and can move up and down. The mounting rod 211 is provided with a plurality of continuously arranged teeth 212 to form a rack 21. The gear meshes with the rack 21. The lower side plate 12 of the lamp body 1 is also provided with a relief groove 121. The gear protrudes from the lower side plate 12 of the lamp body 1 through the relief groove 121. The locking structure 3 is provided on the lamp body 1 and corresponds to the position of the gear structure 25.

[0052] In practice, although the dimensions of the ceiling square tube 10 are specified, the distance D1 between the mounting block 23 and the lamp body 1 can be set according to the corresponding dimensions of the ceiling square tube 10 during the production of the lamp structure in this embodiment, so that the lamp structure will not be too loose when installed on the square tube ceiling. However, if D1 is too close to the height L1 of the ceiling square tube 10, strong friction or even collision may occur between the mounting block 23 and the ceiling square tube 10 and between the lamp body 1 and the square tube during installation, which may damage the lamp structure and the ceiling square tube 10.

[0053] In this embodiment, the mounting assembly 2 also includes a gear structure 25, which meshes with the rack 21 and protrudes from the lower side plate 12 of the lamp body 1 through the clearance groove 121. This allows technicians to directly move the rack 21 by rotating the gear structure 25, thereby adjusting the distance between the lamp body 1 and the mounting block 23 on the rack 21. The operation method is as follows: Before installation, rotate the gear structure 25 to move the mounting block 23 away from the lamp body 1, making the difference between the distance D1 and the height L1 of the lamp body 1 increasingly larger. When the mounting block 23 reaches the upper side of the ceiling square tube 10 through the aforementioned operation method, the ceiling square tube 10 is located between the mounting block 23 and the lamp body 1. At this time, by rotating the gear structure 25, the distance D1 gradually decreases, that is, D1 gets closer and closer to the value of L1, until D1 shrinks to an appropriate size, or even when the mounting block 23 and the lamp body 1 are locked together with the ceiling square tube 10, stop rotating the gear structure 25. At this time, the lamp structure is less likely to loosen. After the gear structure 25 stops rotating, the locking structure 3 is used to lock the gear structure 25, so that the gear structure 25 and the lamp body 1 are relatively stationary, so as to maintain the relative position stability between the lamp body 1, the mounting block 23 and the ceiling square tube 10.

[0054] In this embodiment, the gear structure 25 is provided so that D1 can be adjusted to a sufficiently large size before installation, so that during the process of moving the mounting block 23 to the upper side of the ceiling square tube 10, there will be less or even no strong friction and collision between the mounting block 23 and the ceiling square tube 10, and between the lamp body 1 and the ceiling square tube 10. Finally, D1 is reduced by the gear structure 25, so that the lamp structure is not easy to loosen when installed on the square tube ceiling, which helps to reduce the wear on the lamp structure and the ceiling square tube 10, and also reduces the installation difficulty, making the installation process smoother.

[0055] In some specific embodiments, reference is made to Figure 2 , Figure 3 and Figure 9 The locking structure 3 includes a locking cylinder 31, a locking spring 32, a locking element 33, and a locking groove 2521 on the gear structure 25. The locking cylinder 31 is located on the lamp body 1 and beside the gear structure 25, with its opening facing the gear structure 25. The locking spring 32 is provided inside the locking cylinder 31. One end of the locking spring 32 is connected to the bottom of the locking cylinder 31, and the other end is provided with the locking element 33. The locking groove 2521 is provided on the side wall of the gear structure 25 near the locking cylinder 31. The locking element 33 is matched with the locking groove 2521. During installation, when the gear structure 25 rotates to the point where the locking groove 2521 is directly opposite the opening of the locking cylinder 31, the locking spring 32 pushes the locking element 33 into the locking groove 2521 to lock the gear structure 25.

[0056] When the technician adjusts the position of the rack 21 using the gear structure 25, and ensures that the relative positions of the lamp body 1, the ceiling square tube 10, and the mounting block 23 meet the target requirements, if the gear structure 25 is released directly, the lamp body 1 will move downward under the action of gravity. The rack 21 will be hung on the ceiling square tube 10 due to the limiting effect of the ceiling square tube 10 on the mounting block 23. The gear structure 25 will move downward with the lamp body 1. Since the gear structure 25 and the rack 21 are meshed, the gear structure 25 will rotate during this process.

[0057] To avoid the above situation, a locking structure 3 is provided in this embodiment. The purpose is to lock the gear structure 25 after adjusting the relative distance D1 between the lamp body 1 and the mounting block 23, so that the lamp body 1 and the mounting block 23 are maintained at a relative distance of D1.

[0058] During the production and assembly of the lighting fixture structure, technicians will first adjust the relative distance D1 between the lamp body 1 and the mounting block 23 to a suitable size according to the height L1 of the corresponding ceiling square tube 10. Then, they will adjust the gear structure 25 so that the corresponding locking groove 2521 is aligned with the opening of the locking cylinder 31. After this pre-setting, during installation, when the technicians adjust the gear structure 25 to adjust the relative distance D1 between the lamp body 1 and the mounting block 23 to a suitable size, the locking element 33 in the locking cylinder 31 will be pushed out by the locking spring 32 and will be partially located in the locking groove 2521 and partially located in the locking cylinder 31. This prevents the gear structure 25 from rotating, thus locking the gear structure 25 and restricting the downward movement of the lamp body 1.

[0059] Before the gear structure 25 rotates to the point where the locking groove 2521 is directly opposite the opening of the locking cylinder 31, the side wall of the gear structure 25 near the locking cylinder 31 will press against the locking member 33, allowing the locking spring 32 to fully compress and store energy. This also ensures that when the locking groove 2521 is directly opposite the opening of the locking cylinder 31, the locking spring 32 can quickly push out the locking member 33, completing the locking. When the locking member 33 is in the locked position, the locking spring 32 is still in a compressed and stored state, which helps to improve the locking strength and makes it more difficult for the lamp body 1 to move downwards.

[0060] In some specific embodiments, reference is made to Figure 2 , Figure 3 and Figure 9 The gear structure 25 includes a first gear 251 and a second gear 252 that mesh with each other. The first gear 251 protrudes from the lower side plate 12 of the lamp body 1, and the second gear 252 meshes with the rack 21. The second gear 252 is provided with a plurality of locking grooves 2521, which are evenly arranged around the rotation axis of the second gear 252. The locking element 33 is a locking steel ball.

[0061] The gear structure 25 includes a first gear 251 and a second gear 252 that mesh with each other, instead of using only one gear as the gear structure 25, which helps to reduce the size of the components and facilitates installation. In addition, the smaller diameter of the first gear 251 allows the size of the clearance groove 121 to be reduced accordingly, which reduces the manufacturing difficulty of the lamp structure in this embodiment and minimizes damage to the structural strength of the lamp body 1.

[0062] Specifically, the locking groove 2521 is provided on the second gear 252, and multiple locking grooves 2521 are evenly arranged around the rotation axis of the second gear 252. With the use of locking steel balls as locking elements 33, the lamp body 1 can be locked at different height positions, so that there is a sufficient gap between the lamp body 1 and the ceiling square tube 10, so that technicians can carry out inspection and maintenance.

[0063] During operation, when the locking steel ball is engaged in one of the locking slots 2521, the gear structure 25 can be locked if the technician stops rotating it. If the height of the lamp body 1 needs to be adjusted, the gear structure 25 can be rotated. Utilizing the smooth spherical surface of the locking steel ball, the locking steel ball will disengage from the original locking slot 2521 under the restriction of the locking cylinder 31 until the technician adjusts the height of the lamp body 1. Then, the locking steel ball will engage in the corresponding locking slot 2521, keeping the lamp body 1 at that height.

[0064] In some other embodiments, the second gear 252 has only one locking groove 2521. When the locking member 33 is engaged in the locking groove 2521, the lamp body 1 is at a suitable height and is not easy to loosen on the square tube ceiling.

[0065] In some specific embodiments, reference is made to Figure 3 The inner surface of the locking groove 2521 is spherical or hemispherical.

[0066] Setting the inner surface of the locking groove 2521 into a spherical or hemispherical shape helps to reduce the squeezing force between the locking ball and the opening edge of the locking groove 2521 when the locking ball is released from the locking groove 2521, which helps to protect the locking ball and extend its service life.

[0067] Furthermore, the radius of the inner surface of the locking groove 2521 matches the radius of the outer surface of the locking ball, so that when the gear structure 25 is in the locked state, the locking ball and the locking groove 2521 are not easy to move relative to each other or the relative movement distance is small, thus strengthening the locking effect.

[0068] In some specific embodiments, reference is made to Figures 3 to 5 , Figures 9 to 10The locking structure 3 also includes a locking rod 34 that can drive the locking cylinder 31 to rotate. The locking rod 34 is fixed relative to the lamp body 1 in the height direction. One end of the locking rod 34 is connected to the locking cylinder 31, and the other end passes through the lower side plate 12 of the lamp body 1. A handle 35 is provided at one end of the locking rod 34 that passes through the lower side wall of the lamp body 1. The locking rod 34 is used to make the locking member 33 leave the position corresponding to the locking groove 2521.

[0069] Specifically, the locking lever 34 is also provided with a retaining ring 36, which is securely mounted on the locking lever 34 and cooperates with the handle 35 to clamp the lower side plate 12 of the lamp body 1, so that the locking lever 34 is fixed relative to the lamp body 1 in the height direction.

[0070] The locking lever 34 is designed to allow the locking cylinder 31 to move away from the locking member 33 and engage with the locking groove 2521, enabling the lamp body 1 to descend conveniently and smoothly. For example, if the goal is to lower the lamp body 1 to its lowest possible height, rotating the gear structure 25 would achieve this, but the multiple locking grooves 2521 make this process time-consuming and labor-intensive for technicians. Therefore, in this embodiment, the locking lever 34 is provided. When the lamp body 1 needs to descend directly to its lowest height, rotating the handle 35 causes the locking cylinder 31 to rotate, ensuring that the opening of the locking cylinder 31 is not directly aligned with the side wall of the gear structure 25 with the locking groove 2521. This allows the lamp body 1 to descend conveniently and smoothly, improving the efficiency of inspecting, repairing, or disassembling the lamp structure.

[0071] Furthermore, an annular groove 2522 is provided on the side wall of the second gear 252 near the locking cylinder 31. The annular groove 2522 is coaxially arranged with the second gear 252. Multiple locking grooves 2521 are provided at the bottom of the annular groove 2522 and are evenly spaced along the annular groove 2522. The width of the annular groove 2522 matches the outer diameter of the locking cylinder 31, and the part of the locking cylinder 31 near the opening is also locked in the annular groove 2522. This makes it difficult for the locking cylinder 31 to deviate from its position when the second gear 252 rotates. The opening of the locking cylinder 31 always faces the bottom of the annular groove 2522, so that the locking structure 3 can respond in time and lock the second gear 252.

[0072] Furthermore, the second gear 252 is also provided with a radial groove 2523, which extends radially along the second gear 252. One end of the radial groove 2523 is connected to the annular groove 2522, and the other end extends to the edge of the second gear 252. The locking groove 2521, which is directly opposite the radial groove 2523 in the annular groove 2522, is called the locking main groove. In this embodiment, when the locking member 33 is engaged in the locking main groove and enters the locking state, the radial groove 2523 is in a horizontally extending state. When the distance D1 between the lamp body 1 and the mounting block 23 is close to the height L1 of the ceiling square tube 10 and is not easy to loosen, the locking member 33 is engaged in the locking main groove. At this time, if the size of D1 is further reduced—that is, if the lamp body 1 is further moved upward—the locking member 33 cannot be engaged in the other locking groove 2521. The height position of the lamp body 1 at this time is called the highest position where the lamp body 1 can be locked. The purpose of the radial groove 2523 is to provide a path for the locking cylinder 31 to disengage from the locked position when the annular groove 2522 is present. Once the locking member 33 is engaged in the main locking groove, the locking cylinder 31 can be disengaged from the annular groove 2522 by rotating the handle 35, thus disengaging from the locked position. In actual operation, since it is not easy to observe whether the locking groove 2521 into which the locking member 33 is engaged is the main locking groove, it can be determined that the locking member 33 is engaged in the main locking groove when the lamp body 1 is in its highest lockable position. At this point, the locking cylinder 31 can be disengaged from the annular groove 2522 by rotating the handle 35.

[0073] In some specific embodiments, reference is made to Figures 9 to 12 , Figures 16 to 18 A speed reduction plate structure 26 is provided on the side of the rack 21. The speed reduction plate structure 26 has a speed reduction groove extending in the vertical direction. Multiple protrusions 262 are provided on the two groove walls in the vertical direction, so that a tortuous passage 261 is formed in the speed reduction groove. A horizontally extending slide rail 311 is provided on the side wall of the locking cylinder 31. A speed reduction slider 4 is locked on the slide rail 311. The speed reduction slider 4 corresponds to the position of the passage 261. Rotating the locking rod 34 can make the speed reduction slider 4 enter the passage 261. When the lamp body 1 moves away from the mounting block 23, the speed reduction slider 4 moves along the passage 261 to slow down the moving speed of the lamp body 1.

[0074] Turning handle 35 rotates the locking cylinder 31, allowing the deceleration slider 4 to engage in the passageway 261 of the deceleration groove. As the locking cylinder 31 moves out of its locked position, the lamp body 1 descends. During this descent, the deceleration slider 4 also descends. Since the deceleration plate structure 26 is mounted on the rack 21, and the rack 21 is limited by the ceiling square tube 10's restraint on the mounting block 23, it does not descend with the lamp body 1. This causes the deceleration slider 4 to move downwards along the passageway 261. However, because the passageway 261 has multiple protruding structures 262 on its walls, making the passageway 261 meander, the deceleration slider 4 is hindered by these protruding structures 262 during its movement, slowing its descent.

[0075] The speed reduction plate structure 26 can pass through the first through hole 111. The speed reduction plate structure 26, the speed reduction slider 4, and other structures are set to slow down the descent speed of the lamp body 1, so as to reduce the mutual impact force between the lamp body 1 and the mounting rod 211 when the lamp body 1 descends to the lowest height, thereby protecting the lamp structure and extending the service life of the lamp structure.

[0076] Specifically, the deceleration groove is provided with a left groove wall 264 and a right groove wall 265. The upper side of the protrusion 262 on the left groove wall 264 is provided with a first guide slope 271, which extends from top to bottom along the direction from close to to far away from the left groove wall 264. The upper side of the protrusion 262 on the right groove wall 265 is provided with a second guide slope 272, which extends from top to bottom along the direction from close to to far away from the right groove wall 265.

[0077] The deceleration slider 4 is generally cubic in shape and has an upper side 41, a lower side 42, a left side 43, and a right side 44. A third guide slope 273 is provided between the left side 43 and the lower side 42, extending from top to bottom in a direction close to and away from the left side 43. A fourth guide slope 274 is provided between the right side 44 and the lower side 42, extending from top to bottom in a direction close to and away from the right side 44. Specifically, the first guide slope 271 matches the third guide slope 273, and the second guide slope 272 matches the fourth guide slope 274.

[0078] Furthermore, a fifth guide slope 275 is provided on the lower side of the protrusion 262 on the left groove wall 264, which extends from bottom to top along the direction from close to to far away from the left groove wall 264; a sixth guide slope 276 is provided on the lower side of the protrusion 262 on the right groove wall 265, which extends from bottom to top along the direction from close to to far away from the right groove wall 265.

[0079] On the deceleration slider 4, a seventh guide slope 277 is provided between the left side 43 and the upper side 41, extending from bottom to top in a direction approaching and moving away from the left side 43; an eighth guide slope 278 is provided between the right side 44 and the lower side 42, extending from bottom to top in a direction approaching and moving away from the right side 44. The fifth guide slope 275 matches the seventh guide slope 277, and the sixth guide slope 276 matches the eighth guide slope 278. On the deceleration slider 4, the third guide slope 273 and the eighth guide slope 278 are parallel to each other, and the fourth guide slope 274 and the seventh guide slope 277 are parallel to each other.

[0080] Based on the technical feature that "multiple protrusions 262 are arranged alternately in the vertical direction on the two walls of the deceleration groove", the movement process of the deceleration slider 4 on the passage 261 is as follows:

[0081] Assuming that the deceleration slider 4 deflects towards the left wall 264 after entering the passage 261, during its downward movement, the third guide slope 273 contacts the first guide slope 271, causing the deceleration slider 4 to move to the right. After the third guide slope 273 disengages from the first guide slope 271, the deceleration slider 4 moves downward, and then the second guide slope 272 and the fourth guide slope 274 contact, causing the deceleration slider 4 to move to the left. This process is repeated until the deceleration slider 4 reaches its lowest position. During this downward movement, the deceleration slider 4 moves back and forth, allowing the deceleration slider 4 and the lamp body 1 to automatically and slowly descend.

[0082] Furthermore, the protrusion 262 on the left groove wall 264 is called the left protrusion, and the protrusion 262 on the right groove wall 265 is called the right protrusion. In this embodiment, the first guide slope 271 and the sixth guide slope 276 are parallel to each other between the left protrusion and the right protrusion located above it, and the distance between the first guide slope 271 and the sixth guide slope 276 matches the distance between the third guide slope 273 and the eighth guide slope 278 on the deceleration slider 4, so that the deceleration slider 4 can just pass between the first guide slope 271 and the sixth guide slope 276.

[0083] Between the left protrusion and the right protrusion located below it, the fifth guide slope 275 is parallel to the second guide slope 272, and the distance between the fifth guide slope 275 and the second guide slope 272 matches the distance between the fourth guide slope 274 and the seventh guide slope 277 on the deceleration slider 4, so that the deceleration slider 4 can just pass between the fifth guide slope 275 and the second guide slope 272.

[0084] This configuration ensures a tight fit between the passageway 261 and the deceleration slider 4, resulting in a relatively fixed and stable trajectory for the deceleration slider 4 during its downward movement. This minimizes the risk of displacement or jamming, allowing the lamp body 1 to descend smoothly.

[0085] In actual operation, after rotating the locking lever 34, since the exact position of the deceleration slider 4 on the slide rail 311 cannot be determined, the deceleration slider 4 may not immediately enter the passageway 261. In this case, the operator only needs to keep the deceleration slider 4 against the deceleration plate structure 26. Due to the relative movement between the deceleration plate structure 26 and the deceleration slider 4 in the height direction, when the lamp body 1 descends a short distance, aligning the empty position of the passageway 261 with the deceleration slider 4, the deceleration slider 4 will enter the passageway 261.

[0086] In some specific embodiments, reference is made to Figure 8 and Figure 9 A baffle 263 is provided on the speed reduction plate structure 26 and at the lower end of the passage 261. When the speed reduction slider 4 presses against the baffle 263, the lamp body 1 is in the "lowest height position" mentioned above.

[0087] In some specific embodiments, the handle 35 is provided with a limiting rod 351, and the lower side plate 12 of the lamp body 1 is provided with an arc-shaped groove 122, the central angle of which is 90°. The limiting rod 351 is inserted into the arc-shaped groove 122 and can move along the arc-shaped groove 122. The arc-shaped groove 122 is used to limit the movement of the limiting rod 351 to prevent the handle 35 from rotating too much, which could cause the parts to collide or become misaligned.

[0088] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
