Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a lamp structure that can be installed on a square tube ceiling. Background Art

[0002] In recent years, square tube ceilings have become the preferred roofing solution for many offices and entertainment venues, offering advantages such as wide views, strong air permeability, durability, and easy maintenance. As square tube ceilings become increasingly popular, the variety of supporting tools for square tube ceilings has also gradually increased, among which linear lights installed on square tube ceilings are one of them.

[0003] Existing linear lights installed on square tube ceilings include a lamp body with a screw on its upper side and a rotatable hanging plate near the upper end. Installation typically requires two technicians: one technician holds the lamp body from below, while the other technician reaches over the square tubes or climbs onto the ceiling to adjust the hanging plate's angle so that it can pass between two tubes and finally hang on two adjacent tubes. The technician then uses tools to slowly adjust the relative height between the lamp body and the tubes. This installation process is complex and labor-intensive. Furthermore, in reality, the distance between the tubes in some square tube ceilings is small, making it difficult for technicians to reach in and perform installation adjustments. In some cases, the distance from the ceiling to the ceiling is too close, making it difficult to hang the hanging plate on the tubes. In these situations, installing the linear lights becomes even more difficult. Summary of the Invention

[0023] like Figures 1 to 18 As shown, a lamp structure that can be installed on a square tube ceiling includes a lamp body 1. At least two mounting components 2 are provided on the lamp body 1. The two mounting components 2 are respectively arranged near the two opposite side walls of the lamp body 1; the mounting component 2 includes 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 arranged on the part of the mounting rod 211 located on the upper side of the lamp body 1 through the connecting rod 22 and is separated from the lamp body 1. An elastic structure 24 is provided on the connecting rod 22. During installation, the elastic structure 24 can push the mounting block 23 out so that the ceiling square tube 10 of the square tube ceiling is located between the mounting block 23 and the lamp body 1.

[0024] In this embodiment, when installing the lamp structure on a square tube ceiling, the mounting blocks 23 located on both sides of the lamp body 1 are first guided between adjacent ceiling square tubes 10, and then the lamp body 1 is pushed upward. 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 positioned 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, let alone climb above it, which helps reduce the difficulty of installing the lamp structure, simplify the installation process, and improve installation efficiency.

[0025] In this embodiment, a linear lamp structure is used as an example. Of course, the lamp structure described in this embodiment can also adopt other lamp forms, as long as the structure of this embodiment can be applied to be installed on a square tube ceiling.

[0026] In this embodiment, four mounting components 2 are provided on the lamp body, and the four mounting components 2 are arranged in a matrix.

[0027] In some specific embodiments, reference Figures 1 to 4, a second through hole 2111 is provided on the mounting rod 211, the connecting rod 22 is passed through the second through hole 2111 and can move along the second through hole 2111, one end of the connecting rod 22 is provided with a limit block 221, and the other end is provided with a mounting block 23; the elastic structure 24 includes a tension spring 241, the tension spring 241 is sleeved on the connecting rod 22, one end of the tension spring 241 is connected to the limit block 221, and the other end is connected to the mounting rod 211, or, the elastic structure 24 includes a compression spring, the compression spring 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.

[0028] 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 stopper 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 stopper 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.

[0029] 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 installation component 2 close to the left wall as an example, during installation, it is necessary to first move the installation block 23 to the right so that the installation block 23 is located directly below the gap between the two adjacent ceiling square tubes 10. At this time, the tension spring 241 is in a stretched energy storage state; then move the linear light structure upward and move the installation block 23 into the gap between the two adjacent ceiling square tubes 10. During this process, the tension spring 241 will drive the installation block 23 to squeeze the left one of the two ceiling square tubes 10, but at this time the tension spring 241 is still in a stretched energy storage state; finally, when the installation block 23 reaches the upper side of the gap between the two adjacent ceiling square tubes 10, the tension spring 241 drives the installation 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 lamp body 1 and the left installation block 23. At this time, the tension spring 241 may be in a stretched energy storage state or in a normal state.

[0030] Correspondingly, the installation component 2 on the right is used in the same way as the installation component 2 on the left. The ceiling square tube 10 on the right is located between the lamp body 1 and the installation block 23 on the right. At this time, the linear lamp structure can be hung on the square tube ceiling by relying on the installation blocks 23 on the left and right sides.

[0031] When the elastic structure 24 includes a compression spring, the compression spring sleeve is provided on the connecting rod 22 and is located between the mounting block 23 and the mounting rod 211. Taking the mounting assembly 2 near the left wall as an example, during installation, it is necessary to first move the mounting block 23 to the right so that the mounting block 23 is located directly below the gap between the two adjacent ceiling square tubes 10. At this time, the compression spring is in a compressed energy storage state; then the linear light structure is moved upward, and the mounting block 23 is moved into the gap between the two adjacent ceiling square tubes 10. During this process, the compression spring drives the mounting block 23 to squeeze the left one of the two ceiling square tubes 10, but at this time the compression spring is still in a compressed energy storage state; finally, when the mounting block 23 reaches the upper side of the gap between the two adjacent ceiling square tubes 10, the compression spring drives 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 lamp body 1 and the left mounting block 23. At this time, the compression spring may be in a compressed energy storage state or in a normal state.

[0032] In some specific embodiments, reference Figure 3 、 Figure 14 and Figure 15 A guide slope 231 is provided on the mounting block 23. The mounting block 23 is arranged near one side wall of the lamp body 1, and the guide slope 231 thereon is inclined from top to bottom in the direction of approaching 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.

[0033] The mounting block 23 disposed 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 disposed 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.

[0034] Specifically, the leftmost of the two adjacent ceiling square tubes 10 is referred to as the first ceiling square tube 10, and the rightmost is referred to as the second ceiling square tube 10. In the absence of 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 ceiling square tube 10 and the second ceiling square tube 10. During installation, the linear light structure is first moved below the two ceiling square tubes 10 so that the guide bevel 231 on the leftmost mounting block 23 is located directly below the lower right edge of the first ceiling square tube 10, and the guide bevel 231 on the rightmost mounting block 23 is located directly below the lower left edge of the second ceiling square tube 10. In this way, when the linear light structure is moved upward again, the installation block 23 on the left side smoothly enters the gap between the two adjacent ceiling square tubes 10 under the mutual squeezing action of its guiding inclined surface 231 and the lower right edge of the first ceiling square tube 10. Similarly, the installation block 23 on the right side can also smoothly enter the gap between the two adjacent ceiling square tubes 10 under the mutual squeezing action of its guiding inclined surface 231 and the lower left edge of the second ceiling square tube 10.

[0035] The setting of the guiding 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 is conducive to further simplifying the installation process of the lamp structure and improving the installation efficiency of the lamp structure on the square tube ceiling.

[0036] In some specific embodiments, reference 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 inside 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 is passed 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 is meshed with the rack 21. An avoidance groove 121 is also provided on the lower side plate 12 of the lamp body 1. The gear protrudes from the lower side plate 12 of the lamp body 1 through the avoidance groove 121. The locking structure 3 is provided on the lamp body 1 and corresponds to the position of the gear structure 25.

[0037] In practice, while the dimensions of the square ceiling tube 10 are specified, the distance D1 between the mounting block 23 and the lamp body 1 can be adjusted to the corresponding dimensions of the square ceiling tube 10 when manufacturing the lamp structure of this embodiment, ensuring that the lamp structure is not loose when installed on the square ceiling tube. However, if D1 is too close to the height L1 of the square ceiling tube 10, strong friction or even collision may occur between the mounting block 23 and the square ceiling tube 10, and between the lamp body 1 and the square tube during installation, potentially damaging the lamp structure and the square ceiling tube 10.

[0038] In this embodiment, the mounting assembly 2 further includes a gear structure 25, which is meshed with the rack 21 and protrudes from the lower plate 12 of the lamp body 1 through the avoidance groove 121. This allows a technician 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 following is the operation method: Before installation, the gear structure 25 is rotated to move the mounting block 23 away from the lamp body 1, increasing the difference between the distance D1 and the height L1 of the lamp body 1. 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, the gear structure 25 is rotated to gradually reduce the distance D1, that is, D1 approaches the value of L1, until D1 is reduced to an appropriate value, or even when the mounting block 23 and the lamp body 1 are locked to the ceiling square tube 10. The gear structure 25 is then stopped, and 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, thereby maintaining the relative positions of the lamp body 1, the mounting block 23 and the ceiling square tube 10 stable.

[0039] In this embodiment, a gear structure 25 is provided, and D1 can be adjusted to be large enough before installation, so that in the process of moving the mounting block 23 to the upper side of the ceiling square tube 10, there is less or even no strong friction and collision between the mounting block 23 and the ceiling square tube 10, as well as between the lamp body 1 and the ceiling square tube 10. Finally, D1 is adjusted smaller through the gear structure 25, so that the lamp structure is not easy to loosen when installed on the square tube ceiling, which is beneficial to reducing the wear on the lamp structure and the ceiling square tube 10, and also reduces the difficulty of installation, making the installation process smoother.

[0040] In some specific embodiments, reference Figure 2 、 Figure 3 and Figure 9 The locking structure 3 includes a locking cylinder 31, a locking spring 32, a locking piece 33 and a locking groove 2521 provided on the gear structure 25. The locking cylinder 31 is provided on the lamp body 1 and is located next to the gear structure 25, with its opening facing the gear structure 25. A locking spring 32 is provided in 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 a locking piece 33. The locking groove 2521 is provided on the side wall of the gear structure 25 close to the locking cylinder 31, and the locking piece 33 is matched with the locking groove 2521. During installation, when the gear structure 25 is rotated to the point where the locking groove 2521 is opposite to the opening of the locking cylinder 31, the locking spring 32 pushes the locking piece 33 into the locking groove 2521 to lock the gear structure 25.

[0041] When the technician adjusts the position of the rack 21 through the gear structure 25 and makes 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 directly released, the lamp body 1 will move downward under the action of gravity, and 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, and the gear structure 25 will rise and fall with the lamp body 1. Since the gear structure 25 and the rack 21 are meshed and connected, the gear structure 25 will rotate during this process.

[0042] In order to avoid the above situation, a locking structure 3 is provided in this embodiment. The purpose is to lock the gear structure 25 after the relative distance D1 between the lamp body 1 and the mounting block 23 is adjusted, so that the lamp body 1 and the mounting block 23 are maintained at a relative distance of D1.

[0043] During the production and assembly of the lamp structure, technicians will first adjust the relative distance D1 between the lamp body 1 and the mounting block 23 to an appropriate size based on the height L1 of the corresponding ceiling square tube 10, and then adjust the gear structure 25 so that the corresponding locking groove 2521 is directly opposite the opening of the locking cylinder 31. After such pre-setting, during installation, when the technician adjusts the gear structure 25 so that the relative distance D1 between the lamp body 1 and the mounting block 23 is adjusted to an appropriate size, the locking member 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, thereby preventing the gear structure 25 from rotating, thereby locking the gear structure 25 and restricting the lamp body 1 from moving downward.

[0044] Before the gear structure 25 rotates to the point where the locking groove 2521 faces the opening of the locking cylinder 31, the sidewall of the gear structure 25 near the locking cylinder 31 squeezes the locking member 33, fully compressing and storing energy for the locking spring 32. This also allows the locking spring 32 to quickly push out the locking member 33 when the locking groove 2521 faces the opening of the locking cylinder 31, completing the locking. When the locking member 33 is in the locked position, the locking spring 32 is still in a compressed and stored energy state, which helps to improve the locking strength and prevent the lamp body 1 from moving downward.

[0045] In some specific embodiments, reference Figure 2 、 Figure 3 and Figure 9 The gear structure 25 includes a first gear 251 and a second gear 252 that are meshed with each other. The first gear 251 protrudes from the lower side plate 12 of the lamp body 1, and the second gear 252 is meshed with the rack 21; the second gear 252 is provided with a plurality of locking grooves 2521, and the plurality of locking grooves 2521 are evenly arranged around the rotation axis of the second gear 252, and the locking member 33 is a locking steel ball.

[0046] The gear structure 25 comprises a first gear 251 and a second gear 252 that mesh with each other, rather than using only a single gear. This reduces component size and facilitates installation. Furthermore, the smaller diameter of the first gear 251 allows the size of the avoidance groove 121 to be correspondingly reduced, thus reducing the manufacturing difficulty of the lamp structure in this embodiment and minimizing the structural strength of the lamp body 1.

[0047] Specifically, the locking groove 2521 is provided on the second gear 252, and a plurality of locking grooves 2521 are evenly arranged around the rotation axis of the second gear 252. In combination with the use of locking steel balls as locking members 33, the lamp body 1 can be locked at different height positions, so that there is sufficient space between the lamp body 1 and the ceiling square tube 10 for technicians to conduct inspections, maintenance, and other matters.

[0048] During operation, when the locking steel ball is stuck in one of the locking grooves 2521, if the technician no longer rotates the gear structure 25, the gear structure 25 can be locked; if the height of the lamp body 1 needs to be adjusted, the gear structure 25 can continue to be applied with a rotational force. By utilizing the characteristics of the locking steel ball having a smooth spherical surface, the locking steel ball will be separated from the original locking groove 2521 under the restriction of the locking cylinder 31, until the technician has adjusted the height of the lamp body 1, and the locking steel ball is stuck in the corresponding locking groove 2521, so that the lamp body 1 remains at this height position.

[0049] In some other embodiments, only one locking groove 2521 is provided on the second gear 252. When the locking member 33 is engaged with the locking groove 2521, the lamp body 1 is at a suitable height and is not easily loosened on the square tube ceiling.

[0050] In some specific embodiments, reference Figure 3 The inner surface of the locking groove 2521 is in a spherical crown shape or a hemispherical shape.

[0051] Setting the inner surface of the locking groove 2521 into a spherical crown shape or a hemispherical shape is beneficial to reducing the squeezing force between the locking steel ball and the opening edge of the locking groove 2521 when the locking steel ball leaves the locking groove 2521, which is beneficial to protecting the locking steel ball and extending its service life.

[0052] Furthermore, the radius of the inner surface of the locking groove 2521 matches the radius of the outer surface of the locking steel ball, so that when the gear structure 25 is in the locked state, the locking steel ball and the locking groove 2521 are not prone to relative movement or the relative movement distance is small, thereby enhancing the locking effect.

[0053] In some specific embodiments, reference Figures 3 to 5 、 Figures 9 and 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. The locking rod 34 passes through the lower side wall of the lamp body 1 and is provided with a handle 35 at one end. The locking rod 34 is used to make the locking member 33 leave the position corresponding to the locking groove 2521.

[0054] Specifically, a snap ring 36 is provided on the locking rod 34. The snap ring 36 is tightly arranged on the locking rod 34 and cooperates with the handle 35 to clamp the lower side plate 12 of the lamp body 1, so that the locking rod 34 is relatively fixed to the lamp body 1 in the height direction.

[0055] The purpose of providing the locking lever 34 is to allow the locking cylinder 31 to move away from the position where the locking member 33 can lock with the locking groove 2521, so that the lamp body 1 can be lowered conveniently and smoothly. For example, if one wishes to lower the lamp body 1 to the lowest height position it can reach, while this can be achieved by rotating the gear structure 25, this process is relatively time-consuming and requires the technician's attention due to the multiple locking grooves 2521. Therefore, in this embodiment, a locking lever 34 is provided. When the lamp body 1 needs to be lowered directly to the lowest height position, the locking cylinder 31 can be rotated by rotating the handle 35, so that the opening of the locking cylinder 31 is not aligned with the side wall of the gear structure 25 where the locking groove 2521 is provided. This allows the lamp body 1 to be lowered conveniently and smoothly, thereby improving the efficiency of inspecting, repairing, or removing the lamp structure.

[0056] 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 portion of the locking cylinder 31 near the opening is also retained within the annular groove 2522. This prevents the locking cylinder 31 from deviating 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, allowing the locking structure 3 to respond promptly and lock the second gear 252.

[0057] Furthermore, the second gear 252 is provided with a radial groove 2523. This radial groove 2523 extends radially along the second gear 252, with one end communicating with the annular groove 2522 and the other end extending to the edge of the second gear 252. The locking groove 2521 within the annular groove 2522, directly opposite the radial groove 2523, is referred to as the main locking groove. In this embodiment, when the locking member 33 engages with the main locking groove and enters the locked state, the radial groove 2523 is in a horizontally extended state. When the distance D1 between the lamp body 1 and the mounting block 23 approaches the height L1 of the ceiling square tube 10 and is not easily loosened, the locking member 33 engages with the main locking groove. At this point, if the distance D1 is further reduced—in other words, if the lamp body 1 is further moved upward—the locking member 33 will no longer be able to engage with any other locking groove 2521. The height position of the lamp body 1 at this point is referred to as the highest position at which the lamp body 1 can be locked. The radial groove 2523 is provided to provide a path for the locking cylinder 31 to disengage from the locked position when the annular groove 2522 is provided. Once the locking member 33 is engaged in the main locking groove, the locking cylinder 31 can be disengaged from the annular groove 2522 through the radial groove 2523 by rotating the handle 35, thereby disengaging from the locked position. In actual operation, since it is not easy to easily verify whether the locking groove 2521 in 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 the highest position capable of being locked. At this point, the locking cylinder 31 can be disengaged from the annular groove 2522 through the radial groove 2523 by rotating the handle 35.

[0058] In some specific embodiments, reference Figures 9 to 12 、 Figures 16 to 18 A deceleration plate structure 26 is provided on the side of the rack 21, and a deceleration groove extending in the up-down direction is provided on the deceleration plate structure 26. A plurality of protrusion structures 262 are staggered in the up-down direction on the two groove walls of the deceleration groove, so that a tortuous aisle 261 is formed in the deceleration groove; a horizontally extending slide rail 311 is provided on the side wall of the locking cylinder 31, and a deceleration slider 4 is clamped on the slide rail 311. The deceleration slider 4 corresponds to the position of the aisle 261. Rotating the locking rod 34 can make the deceleration slider 4 enter the aisle 261. When the lamp body 1 moves away from the mounting block 23, the deceleration slider 4 moves along the aisle 261 to slow down the movement speed of the lamp body 1.

[0059] By turning the handle 35 and rotating the locking cylinder 31, the deceleration slider 4 can be stuck into the aisle 261 of the deceleration groove. Since the locking cylinder 31 has left the locking position, the lamp body 1 will drop. During the descent of the lamp body 1, the deceleration slider 4 will also drop. Since the deceleration plate structure 26 is set on the rack 21, the rack 21 will not drop along with the lamp body 1 due to the limiting effect of the ceiling square tube 10 on the mounting block 23, so that the deceleration slider 4 will move from top to bottom along the aisle 261. However, since the groove wall of the aisle 261 is provided with a plurality of protruding structures 262, the aisle 261 extends in a zigzag manner. During the movement of the deceleration slider 4, it will be blocked by the protruding structure 262, slowing down the downward movement speed.

[0060] The deceleration plate structure 26 can pass through the first through hole 111. The deceleration plate structure 26, the deceleration slider 4 and other structures are provided to slow down the descent speed of the lamp body 1, so that the mutual impact force between the lamp body 1 and the mounting rod 211 is reduced when the lamp body 1 descends to the lowest height, thereby protecting the lamp structure and extending the service life of the lamp structure.

[0061] Specifically, a left groove wall 264 and a right groove wall 265 are provided in the deceleration groove, and a first guide slope 271 is provided on the upper side of the raised structure 262 on the left groove wall 264, which extends from the top to the bottom in a direction close to and away from the left groove wall 264; a second guide slope 272 is provided on the upper side of the raised structure 262 on the right groove wall 265, which extends from the top to the bottom in a direction close to and away from the right groove wall 265.

[0062] The deceleration slider 4 is generally in the shape of a cube 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. The third guide slope 273 extends from top to bottom, approaching and away from the left side 43. A fourth guide slope 274 is provided between the right side 44 and the lower side 42. The fourth guide slope 274 extends from top to bottom, approaching and away from the right side 44. The first guide slope 271 matches the third guide slope 273, and the second guide slope 272 matches the fourth guide slope 274.

[0063] Furthermore, a fifth guide slope 275 is provided on the lower side of the protruding structure 262 provided on the left groove wall 264, which extends from the bottom to the top in a direction close to and away from the left groove wall 264; a sixth guide slope 276 is provided on the lower side of the protruding structure 262 provided on the right groove wall 265, which extends from the bottom to the top in a direction close to and away from the right groove wall 265.

[0064] 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, approaching and 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, approaching and away from the right side 44. The fifth guide slope 275 mates with the seventh guide slope 277, and the sixth guide slope 276 mates with 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.

[0065] Combined with the technical feature that "a plurality of protrusion structures 262 are arranged staggered in the vertical direction on the two groove walls of the deceleration groove", the movement process of the deceleration slider 4 on the aisle 261 is as follows: Assuming that the deceleration slider 4 enters the aisle 261 and deflects toward the left groove wall 264, 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 the first guide slope 271, the deceleration slider 4 moves downward, and then the second guide slope 272 contacts the fourth guide slope 274, causing the deceleration slider 4 to move to the left. This process repeats until the deceleration slider 4 descends to its lowest position and stops. During this downward movement, the deceleration slider 4 reciprocates left and right, allowing the deceleration slider 4 and the lamp body 1 to automatically descend slowly.

[0066] Furthermore, the protrusion structure 262 provided on the left groove wall 264 is referred to as the left protrusion, and the protrusion structure 262 provided on the right groove wall 265 is referred to as the right protrusion. In this embodiment, between the left protrusion and the right protrusion located above it, the first guide slope 271 and the sixth guide slope 276 are parallel to each other, 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 pass between the first guide slope 271 and the sixth guide slope 276.

[0067] 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.

[0068] This arrangement allows the passage 261 to fit tightly with the deceleration slider 4, and the movement trajectory of the deceleration slider 4 during the downward movement is relatively fixed and stable, with less displacement and jamming, so that the lamp body 1 can be smoothly lowered.

[0069] In actual operation, after rotating the locking lever 34, the deceleration slider 4 may not immediately enter the aisle 261 because it is uncertain where the deceleration slider 4 is located on the slide rail 311. In this case, the operator only needs to keep the deceleration slider 4 against the deceleration brake structure 26. Since the deceleration brake structure 26 and the deceleration slider 4 can move relative to each other in the height direction, when the lamp body 1 is lowered a short distance, the vacant position in the aisle 261 is aligned with the deceleration slider 4, and the deceleration slider 4 will enter the aisle 261.

[0070] In some specific embodiments, reference Figure 8 and Figure 9 A baffle 263 is provided on the deceleration plate structure 26 and at the lower end of the aisle 261. When the deceleration slider 4 is pressed against the baffle 263, the lamp body 1 is at the "lowest height position" mentioned above.

[0071] In some specific embodiments, the handle 35 is provided with a limiting rod 351. The lower side panel 12 of the lamp body 1 is provided with an arcuate groove 122, which has a central angle of 90°. The limiting rod 351 is inserted into and movable along the arcuate groove 122. The arcuate groove 122 is used to limit the movement of the limiting rod 351, preventing the handle 35 from rotating excessively, which could cause component collision or misalignment.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
