Description

Technical Field

[0001] The invention relates to the technical field of linear lamps, and in particular to a linear lamp with a retractable end cover. Background Art

[0002] LED linear light series is a high-end flexible decorative light, which features low power consumption, long life, high brightness, easy bending, maintenance-free, etc. It is particularly suitable for indoor and outdoor entertainment venues, building outlines and billboard production. Linear lights are generally fixed to the wall by screws. The interior of the linear light contains important components such as light source and circuit. In order to prevent foreign objects such as dust and insects from entering the lamp body, end covers are usually installed on the side of the linear light to protect the components inside the linear light.

[0003] The end caps of existing linear lights are usually only used to protect the end sides of the linear lights, and the end caps and the linear lights are fixed by bolts. However, when inspecting and maintaining the linear lights, tools are needed to unscrew the bolts one by one, and the bolts need to be properly kept during the removal process, otherwise the bolts are easily lost, which may affect the subsequent reinstallation or require additional matching bolts to be found, increasing maintenance costs and time. In addition, after long-term use, the bolts may rust, corrode or have thread slippage, which increases the difficulty of subsequent disassembly.

[0004] In addition, some linear lights are fixed on the wall by ropes during installation. Although some ropes are provided with installation accessories with rope adjustment buckles, the effective length of the rope can be changed by pulling the rope through the adjustment buckle to adjust the hanging height of the linear light, but this method can only adjust the height. The lighting direction of the linear light itself is still fixed, and it cannot be rotated around the rope to flexibly adjust the angle of the linear light according to actual needs, which reduces the use effect of the device. In view of this, we propose a linear light with a retractable end cover. Summary of the invention

[0005] The object of the present invention is to provide a linear light with a retractable end cover to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a linear lamp with a retractable end cover, comprising a lamp body, both sides of the lamp body are slidably clamped with mounting covers, the mounting cover is provided with a clamping mechanism that fixes the mounting cover on the lamp body through elastic movement, and the mounting cover is also provided with an angle adjustment mechanism and a limit mechanism, and the angle of the lamp body is driven by the angle adjustment mechanism to adjust according to lighting requirements;

[0007] After the angle of the lamp body is adjusted, the angle adjustment mechanism is limited by the limiting mechanism, and the auxiliary clamping mechanism is clamped to the lamp body.

[0008] As a further improvement of the present technical solution, the clamping mechanism includes at least two movable blocks slidably connected in the mounting cover slots, and the two movable blocks are fixedly connected with connecting rods on one side close to the lamp body. Limiting holes are provided on both sides of the lamp body, and the limiting holes are clamped and adapted to the connecting rods.

[0009] As a further improvement of the technical solution, the angle adjustment mechanism includes a hollow column fixedly connected to the side of the mounting cover away from the lamp body, and the outer wall of the hollow column is rotatably connected to a circular ring, and the circular ring is provided with a plurality of circular holes.

[0010] As a further improvement of the technical solution, a retractor is movably sleeved on the outer wall of the circular ring, and a fixing seat is fixedly connected to a side of the retractor away from the circular ring.

[0011] As a further improvement of the present technical solution, the limiting mechanism includes at least a sliding rod slidably connected to the inside of the hollow column, and two limiting rods are fixedly connected to one side of the sliding rod located outside the hollow column. The limiting rods pass through the circular holes of the circular ring and the mounting cover in sequence, and extend into the sliding grooves provided in the mounting cover. A No. 3 return spring is fixedly connected to one side of the sliding rod located inside the hollow column, and the No. 3 return spring is sleeved on the outer wall of the sliding rod.

[0012] As a further improvement of the technical solution, a moving rod is slidably connected inside the connecting rod, and the moving rod is arranged to pass through one side of the moving block, and the side of the moving rod close to the limiting rod is arranged in an inclined surface.

[0013] As a further improvement of the present technical solution, a fixed block is fixedly connected in the mounting cover slide groove, and a No. 1 return spring is fixedly connected to both sides of the fixed block, and the two No. 1 return springs are fixedly connected to the outer walls of the adjacent movable blocks on one side away from the fixed block.

[0014] As a further improvement of the technical solution, a No. 2 return spring is fixedly connected to one side of the moving rod, and a side of the No. 2 return spring away from the moving rod is fixedly connected to the inner wall of the connecting rod.

[0015] As a further improvement of the technical solution, two rectangular grooves are provided on one side of the mounting cover close to the hollow column, a lever is fixedly connected to one side of the moving block close to the rectangular groove, and the lever extends to the outside of the rectangular groove.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the linear light with retractable end cap, the mounting cover and the lamp body are fixed by manually moving the clamping mechanism. During the installation and disassembly process of the clamping mechanism, there are no small parts such as bolts, thereby effectively avoiding the situation where the bolts are lost due to poor storage during the disassembly process, thereby avoiding the additional cost and time consumption caused by finding matching bolts.

[0018] 2. In the linear lamp with a retractable end cap, the lamp body is driven to rotate by manually rotating the angle adjustment mechanism, so that the irradiation direction of the light of the lamp body can be adjusted according to different usage scenarios;

[0020] While the limit rod fixes the angle adjustment mechanism, the limit rod can resist the moving rod. Under the elastic force of the limit rod, the excessive displacement of the connecting rod due to accidental touching can be effectively limited, further ensuring the stability of the connection between the installation cover and the lamp body.

[0033] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 7 As shown, the present embodiment provides a linear lamp with a retractable end cap, including a lamp body 100, both sides of the lamp body 100 are slidably clamped with mounting covers 110, the mounting covers 110 can protect the end sides of the lamp body 100, and prevent a large amount of dust and other foreign matter from entering the interior of the lamp body 100, the mounting cover 110 is provided with a clamping mechanism 200 that fixes the mounting cover 110 on the lamp body 100 through elastic movement, so as to fix the mounting cover 110 and the lamp body 100, and the mounting cover 110 is also provided with an angle adjustment mechanism 300 and a limiting mechanism 400, according to different lighting requirements, the lamp body 100 is driven to rotate by the angle adjustment mechanism 300, so that the projection direction of the light of the lamp body 100 can be more accurately controlled;

[0035] After the angle of the lamp body 100 is adjusted, the angle adjustment mechanism 300 is limited by the limiting mechanism 400 to ensure the stability of the lamp body 100 after the angle adjustment, and the auxiliary clamping mechanism 200 clamps the lamp body 100, further improving the stability of the clamping between the clamping mechanism 200 and the lamp body 100.

[0036] The present invention takes into account that the end cap of the existing linear lamp protects the end side of the linear lamp, and the end cap and the linear lamp are fixed by bolts. However, when inspecting and maintaining the linear lamp, it is necessary to use tools to unscrew the bolts one by one, and the bolts need to be properly kept during the removal process, otherwise the bolts are easily lost, and after long-term use, the bolts may rust, corrode or have thread stripping, thereby increasing the difficulty of subsequent removal; therefore, a clamping mechanism 200 is provided, and the mounting cover 110 and the lamp body 100 are fixed by elastic movement of the clamping mechanism 200. During the fixing and removal of the mounting cover 110, no external tools are required. Compared with the bolt fixing method, the clamping mechanism 200 does not have small parts such as bolts, thereby effectively avoiding the situation where the bolts are lost due to poor storage during the removal process, thereby avoiding the extra cost and time consumption caused by finding matching bolts;

[0037] In addition, some linear lights are fixed on the wall by ropes during installation. Although some ropes are provided with installation accessories with rope adjustment buckles, the effective length of the rope can be changed by pulling the rope through the adjustment buckle to adjust the hanging height of the linear light, but this method can only adjust the height, and the lighting direction of the linear light itself is still fixed; therefore, an angle adjustment mechanism 300 and a limiting mechanism 400 are provided, and the angle adjustment mechanism 300 drives the installation cover 110 and the lamp body 100 to rotate, so as to adjust the lighting angle of the lamp body 100 according to different needs. After the angle adjustment mechanism 300 is adjusted, the angle adjustment mechanism 300 is fixed by elastic movement of the limiting mechanism 400, so as to ensure the stability of the lamp body 100 after the angle adjustment;

[0038] Furthermore, while the limiting mechanism 400 elastically moves to limit the angle adjustment mechanism 300, it can abut against one side of the clamping mechanism 200. When the clamping mechanism 200 is accidentally touched, the elastic force of the limiting mechanism 400 can effectively limit the excessive displacement of the clamping mechanism 200, further ensuring the stability of the clamping between the clamping mechanism 200 and the lamp body 100.

[0039] Considering the need to fix the mounting cover 110 and the lamp body 100, Figure 3 and Figure 5-Figure 6 As shown, the specific structure of the clamping mechanism 200 is further disclosed. The clamping mechanism 200 at least includes two moving blocks 210 slidably connected in the clamping groove of the installation cover 110. The two moving blocks 210 are fixedly connected with a connecting rod 211 on one side close to the lamp body 100. Limiting holes are provided on both sides of the lamp body 100, and the limiting holes are clamped and adapted to the connecting rod 211. The movement of the moving blocks 210 drives the connecting rod 211 to move, so that the connecting rod 211 is clamped into the limiting hole of the lamp body 100, thereby fixing the installation cover 110 and the lamp body 100.

[0040] In different usage scenarios, there are different requirements for the irradiation direction of the light of the lamp body 100, such as Figure 4 and Figure 5 As shown, the specific structure of the angle adjustment mechanism 300 is further disclosed. The angle adjustment mechanism 300 includes a hollow column 310 fixedly connected to the side of the installation cover 110 away from the lamp body 100. The outer wall of the hollow column 310 is rotatably connected to a ring 320, and the ring 320 is provided with a plurality of circular holes. The installation cover 110 is driven to rotate manually by the hollow column 310. Since the installation cover 110 and the lamp body 100 are fixed by the clamping mechanism 200, the rotation of the installation cover 110 drives the lamp body 100 to rotate, thereby adjusting the angle of the lamp body 100, and then the distribution of light in space can be changed according to different needs.

[0041] The lamp body 100 is usually fixed to the wall by bolts or ropes. Considering that the hanging height of the lamp body 100 can be adjusted at any time, such as Figure 1 As shown, the outer wall of the ring 320 is fixedly connected with a retractor 120, and the side of the retractor 120 away from the ring 320 is fixedly connected with a fixing seat 121. The retractor 120 is mainly composed of a reel, an elastic energy storage element, a braking element and a shell. According to the lifting height, the length of the rope in the retractor 120 is adjusted under the pull of external force. The retractor 120 is a prior art and will not be described in detail here. Adjusting the length of the rope of the retractor 120 means adjusting the lifting height of the lamp body 100, so as to facilitate the subsequent cleaning of the lamp body 100 or adjust the lighting range of the lamp body 100.

[0042] After the angle of the lamp body 100 is adjusted, the stability of the lamp body 100 needs to be ensured. Figure 5 and Figure 7 As shown, the specific structure of the limiting mechanism 400 is further disclosed. The limiting mechanism 400 at least includes a sliding rod 410 slidably connected to the inside of the hollow column 310. The sliding rod 410 is located on one side of the outside of the hollow column 310 and is fixedly connected to two limiting rods 411. The limiting rods 411 pass through the circular holes of the ring 320 and the mounting cover 110 in sequence, and extend into the sliding grooves provided in the mounting cover 110.

[0043] When the angle of the lamp body 100 needs to be adjusted, the slide bar 410 is manually pulled to drive the limit rod 411 to move, and the limit rod 411 is pulled out of the circular hole of the ring 320, so that the limit rod 411 does not limit the mounting cover 110 and the ring 320, so that the hollow column 310 can be twisted;

[0044] After the angle adjustment of the lamp body 100 is completed, the limiting rod 411 is manually pushed and passed through the holes of the ring 320 and the mounting cover 110 in sequence, so as to realize the clamping and fixing between the ring 320 and the hollow column 310, thereby ensuring the stability of the lamp body 100 after the angle adjustment is completed;

[0045] The sliding rod 410 is located on one side of the hollow column 310 and is fixedly connected with a No. 3 return spring 412, and the No. 3 return spring 412 is sleeved on the outer wall of the sliding rod 410. The No. 3 return spring 412 is set, and the elastic force of the No. 3 return spring 412 itself can keep the sliding rod 410 in a certain position, avoiding the sliding rod 410 and the limiting rod 411 from shaking due to some external force, causing the limiting rod 411 to escape from the mounting cover 110 and the ring 320, thereby ensuring the stability of the limiting rod 411 after insertion.

[0046] To prevent the connecting rod 211 from accidentally coming out of the lamp body 100, Figure 5-Figure 7 As shown, a moving rod 213 is slidably connected inside the connecting rod 211, and the moving rod 213 is arranged to pass through one side of the moving block 210, and the side of the moving rod 213 close to the limiting rod 411 is arranged in an inclined surface. When the limiting rod 411 is inserted into the mounting cover 110, the limiting rod 411 abuts against the moving rod 213. When the connecting rod 211 is accidentally touched, it moves, and then the connecting rod 211 abuts against the moving rod 213, driving the moving rod 213 to move. Due to the elastic force of the No. 3 reset spring 412, the limiting rod 411 can abut against the moving rod 213, preventing the moving rod 213 from following the connecting rod 211 to produce excessive displacement, thereby preventing the moving rod 213 and the connecting rod 211 from escaping from the limiting hole of the lamp body 100, thereby ensuring the stable connection between the components and reducing the risk of structural damage caused by misoperation.

[0047] In order to ensure the stability of the connection rod 211 being connected to the lamp body 100, Figure 5 and Figure 7 As shown, a fixed block 111 is fixedly connected in the slide groove of the mounting cover 110, and a No. 1 return spring 212 is fixedly connected to both sides of the fixed block 111, and the two No. 1 return springs 212 are respectively fixedly connected to the outer walls of the adjacent moving blocks 210 on one side away from the fixed block 111. Under the elastic force of the No. 1 return spring 212 itself, the moving block 210 can be maintained in a certain position, thereby ensuring the stability of the connecting rod 211 being clamped into the lamp body 100.

[0048] When the mounting cover 110 rotates, the moving rod 213 can still abut against the limiting hole of the lamp body 100. Figure 5-Figure 7As shown, one side of the moving rod 213 is fixedly connected with a No. 2 return spring 214, and the side of the No. 2 return spring 214 away from the moving rod 213 is fixedly connected to the inner wall of the connecting rod 211. When the hollow column 310 is rotated, the mounting cover 110 is driven to rotate. At this time, under the elastic force of the No. 2 return spring 214, the moving rod 213 can still resist the inner wall of the limiting hole of the lamp body 100, and will not be offset due to the inertia generated by the rotation, thereby further enhancing the positioning effect of the moving rod 213.

[0049] In order to manually move the moving block 210 for movement, as Figure 4 and Figure 7 As shown, two rectangular grooves are opened on one side of the mounting cover 110 close to the hollow column 310, and a lever 220 is fixedly connected to one side of the moving block 210 close to the rectangular groove, and the lever 220 extends to the outside of the rectangular groove. The moving block 210 is moved by manually pulling the lever 220.

[0050] Working principle: After assembling the lamp body 100, pull the slide bar 410 out of the slide groove of the installation cover 110 by one hand, and then the No. 3 return spring 412 is deformed. Then, pull the two levers 220 closer together with the other hand, and the movement of the lever 220 drives the moving block 210 to move, thereby driving the connecting rod 211 and the moving rod 213 to move. At this time, the No. 1 return spring 212 is squeezed and deformed, and then the installation cover 110 is clamped to the port of the lamp body 100, and then manually loosened. The lever 220 is opened, and the moving block 210 is driven to reset and move under the force of the No. 1 reset spring 212 to restore the deformation, thereby driving the connecting rod 211 to move, so that the connecting rod 211 is clamped into the limiting hole of the lamp body 100, so as to fix the mounting cover 110 and the lamp body 100, and then the fixing seat 121 can be fixed to the wall by bolts. At the same time, according to different lighting requirements, the length of the rope of the retractor 120 is adjusted by manually adjusting the retractor 120, so as to adjust the hanging height of the lamp body 100;

[0051] Since different usage scenarios have different requirements for the irradiation direction and angle of the light of the lamp body 100, when it is necessary to adjust the angle of the lamp body 100, the sliding rod 410 is manually pulled to drive the limiting rod 411 to move, and the limiting rod 411 is pulled out of the circular hole of the circular ring 320, and then the hollow column 310 is manually rotated to drive the installation cover 110 to rotate, thereby driving the lamp body 100 to rotate, so as to adjust the angle of the lamp body 100 according to different needs. After the angle adjustment of the lamp body 100 is completed, the limiting rod 411 is manually pushed to pass the limiting rod 411 through the holes of the circular ring 320 and the installation cover 110 in turn, so as to realize the clamping and fixing between the circular ring 320 and the hollow column 310, thereby ensuring the stability of the lamp body 100 after the angle adjustment is completed.

[0052] When the limiting rod 411 is inserted into the mounting cover 110, the limiting rod 411 abuts against the inclined end of the moving rod 213, effectively preventing the lever 220 from being accidentally touched. Since the moving rod 213 is located inside the connecting rod 211, when the lever 220 drives the connecting rod 211 to move, the connecting rod 211 abuts against the moving rod 213, trying to drive the moving rod 213 to move. Since the limiting rod 411 abuts against the moving rod 213, the elastic force between the No. 2 return spring 214 and the No. 3 return spring 412 cooperates with each other, thereby further strengthening the limiting effect of the moving rod 213, thereby ensuring the stability of the card connection between the lamp body 100 and the mounting cover 110.

[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
