Description

Technical Field

[0001] This application relates to the field of elevator technology, specifically to a safety lighting device for elevators. Background Technology

[0002] The lights inside the elevator are used to provide illumination for the elevator interior and to provide sufficient light for passengers.

[0003] Chinese utility model patent CN221825267U discloses an elevator interior lighting device. It utilizes a bidirectional screw to rotate a transmission plate, which drives a fixing rod to insert into the fixing hole of a lamp holder, facilitating the installation and removal of the lighting fixture. However, this solution is only suitable for small lamps. Elevator ceiling lights are typically large, elongated fixtures, and the above method, using only one set of fixing components, cannot stably install such large, elongated fixtures.

[0004] Therefore, this application provides a safety lighting device for elevators to solve the above problems. Utility Model Content

[0005] This application provides a safety lighting device for elevators, aiming to solve the problems mentioned in the background art, such as that the existing lighting equipment fixing components are only suitable for small lamps, while the lamps inside the elevator ceiling are usually long and large lamps, and it is impossible to stably install long and large lamps by using only one set of fixing components.

[0006] To achieve the above objectives, this application provides the following technical solution: a safety lighting device for elevators, including a lighting lamp and a lamp holder disposed at the bottom of the lighting lamp for mounting the lighting lamp;

[0007] To facilitate the installation of the elongated lighting fixture: a mounting frame is provided outside the lamp holder for mounting the lamp holder; a fixing plate is provided at the bottom of the mounting frame for mounting the mounting frame; an active fixing component is provided at one end of the mounting frame for fixing one end of the lamp holder; a passive fixing component is provided at the other end of the mounting frame for fixing the other end of the lamp holder; and a linkage component is provided between the active fixing component and the passive fixing component for linkage between the active fixing component and the passive fixing component. When installing the lighting fixture, rotating the first bidirectional screw causes the symmetrically arranged first clamping jaws to move in opposite directions. The rotation of the first bidirectional screw drives the first bevel gear to rotate synchronously. The first bevel gear meshes with the third bevel gear, thereby driving the connecting rod to rotate. The connecting rod drives the fourth bevel gear to rotate. The fourth bevel gear meshes with the second bevel gear, thereby driving the second bidirectional screw to rotate, causing the second clamping jaw to move synchronously with the first clamping jaw, facilitating the placement of the lamp holder inside the mounting frame. Then, rotating the first bidirectional screw in the opposite direction causes the first clamping jaw and the second clamping jaw to move in opposite directions. The lamp holder is clamped and fixed at both ends to achieve stable and convenient installation of the elongated lighting fixture. When the lamp holder is disassembled, it may fall due to its own weight. When the anti-fall hole of the lamp holder moves to the position of the insert block, the elastic block's restoring force pushes the insert block into the anti-fall hole, temporarily limiting the lamp holder's continued fall. This prevents workers from being injured by the falling lighting fixture while disassembling the lamp and turning the first bidirectional screw. Finally, by manually pulling the lamp holder, the anti-fall hole and the insert block press against each other, causing the insert block to move out of the anti-fall hole, completing the disassembly of the lighting fixture.

[0008] Preferably, to facilitate the fixing of the lamp holder: the bottom end of the lighting lamp is fixedly connected to the top end of the lamp holder, and the outer walls at both ends of the lamp holder are respectively provided with fixing holes for inserting the active fixing component and the passive fixing component. By inserting the first clamp and the second clamp into the fixing holes at both ends of the lamp holder, the movement of the lamp holder is restricted, thereby achieving stable installation of the elongated lighting lamp.

[0009] Preferably, to facilitate the installation of the lamp holder: the bottom end of the mounting frame is fixedly connected to the top end of the fixing plate, and the outer walls at both ends of the mounting frame are respectively provided with insertion holes for inserting the active fixing component and the passive fixing component. The mounting frame surrounds the lamp holder for positioning, and the insertion holes facilitate the insertion of the first gripper and the second gripper.

[0010] Preferably, to facilitate fixing one end of the lamp holder: the active fixing component includes first grippers symmetrically arranged on both sides of one end of the mounting frame for clamping one end of the lamp holder; a first bidirectional screw threaded through one end of the first grippers for driving the first grippers to move; a first fixing rod threaded through one end of the first grippers for limiting the rotation of the first grippers; a first protective cover fixedly connected to the top of the fixing plate for mounting the first bidirectional screw and the first fixing rod; and a first bevel gear disposed at one end of the first bidirectional screw for cooperating with the linkage. By rotating the first bidirectional screw, the symmetrically arranged first grippers are driven to move towards or away from each other, thereby causing the first grippers to insert into the fixing holes and fixing one end of the lamp holder.

[0011] Preferably, to facilitate fixing the other end of the lamp holder: the passive fixing component includes second grippers symmetrically arranged on both sides of the other end of the mounting frame for clamping the other end of the lamp holder; a second bidirectional screw inserted through one end of the second grippers for driving the movement of the second grippers; a second fixing rod inserted through one end of the second grippers for limiting the rotation of the second grippers; a second protective cover fixedly connected to the top of the fixing plate for mounting the second bidirectional screw and the second fixing rod; and a second bevel gear disposed at one end of the second bidirectional screw for cooperating with the linkage. By rotating the second bidirectional screw, the symmetrically arranged second grippers are driven to move towards or away from each other, thereby causing the second grippers to insert into the fixing holes and fixing the other end of the lamp holder.

[0012] Preferably, for the synchronous movement of the first and second grippers: the linkage includes a third bevel gear disposed at the top of the fixed plate for meshing with the first bevel gear, a fourth bevel gear disposed at the top of the fixed plate for meshing with the second bevel gear, and a connecting rod fixedly connected between the third and fourth bevel gears for linkage between the third and fourth bevel gears. The first bevel gear drives the third bevel gear to rotate, and the third bevel gear drives the fourth bevel gear to rotate via the connecting rod, thereby driving the second bevel gear to rotate, thus achieving synchronous movement of the first and second grippers.

[0013] Preferably, to prevent the lighting fixture from falling: the mounting frame has a fall arrestor on the side facing the lamp holder, the outer wall of the lamp holder has a fall arrestor hole for inserting the fall arrestor, and the interior of the mounting frame has a cavity for installing the fall arrestor, the inner wall of the cavity has a through hole. When the first and second grippers move away from the fixing hole, the lighting fixture and the lamp holder fall under their own weight. When the fall arrestor hole moves to the position of the insertion block, the elastic block's restoring force causes the insertion block to insert into the fall arrestor hole, restricting the lamp holder's continued movement and thus preventing workers from being injured. By having workers apply further external force to pull the lamp holder, the lamp holder can be disassembled.

[0014] Preferably, the fall arrestor includes a plug inserted inside the through hole for insertion into the fall arrestor hole, an elastic block disposed at one end of the plug for pushing the plug, and a limiting plate disposed between the plug and the elastic block for restricting the movement of the plug.

[0015] This application utilizes a design incorporating a lamp holder, mounting frame, active fixing component, passive fixing component, linkage component, and anti-fall component. By rotating the first bidirectional screw, the symmetrically arranged first grippers move in opposite directions. Under the action of the linkage component, the second gripper moves synchronously with the first gripper, placing the lamp holder inside the mounting frame. Then, rotating the first bidirectional screw in the opposite direction causes the first and second grippers to clamp and fix the two ends of the lamp holder, achieving stable and convenient installation of long strip lighting fixtures. When the lamp holder is disassembled, it may fall. When the anti-fall hole moves to the insertion block position, the insertion block inserts into the anti-fall hole, limiting the lamp holder's continued fall and thus preventing workers from being injured by the lighting fixture during disassembly.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This embodiment provides a safety lighting device for elevators, such as... Figure 1-6 As shown, the lighting device includes a lighting lamp 1 and a lamp holder 2 disposed at the bottom of the lighting lamp 1 for mounting the lighting lamp 1;

[0026] To facilitate the installation of the long strip lighting lamp 1: a mounting frame 3 is set outside the lamp holder 2 for mounting the lamp holder 2; a fixing plate 4 is set at the bottom of the mounting frame 3 for mounting the mounting frame 3; an active fixing component 5 is set at one end of the mounting frame 3 for fixing one end of the lamp holder 2; a passive fixing component 6 is set at the other end of the mounting frame 3 for fixing the other end of the lamp holder 2; and a linkage component 7 is set between the active fixing component 5 and the passive fixing component 6 for linkage between the active fixing component 5 and the passive fixing component 6. When installing the lighting lamp 1, rotating the first bidirectional screw 52 causes the symmetrically arranged first clamping jaws 51 to move in opposite directions. The rotation of the first bidirectional screw 52 drives the first bevel gear 55 to rotate synchronously. The first bevel gear 55 meshes with the third bevel gear 71, thereby driving the connecting rod 73 to rotate. The connecting rod 73 drives the fourth bevel gear 72 to rotate. The fourth bevel gear 72 meshes with the second bevel gear 65, thereby driving the second bidirectional screw 62 to rotate, causing the second clamping jaw 61 to move synchronously with the first clamping jaw 51, facilitating the placement of the lamp holder 2 inside the mounting frame 3. Then, rotating the first bidirectional screw 52 in the opposite direction causes the first clamping jaws 51 and the third bevel gear 71 to move synchronously. The two grippers 61 clamp and fix the two ends of the lamp holder 2 respectively, realizing the stable and convenient installation of the long strip lighting lamp 1. At the same time, when the lamp holder 2 is disassembled, the lamp holder 2 will fall under its own weight. When the anti-fall hole of the lamp holder 2 moves to the position of the insertion block 81, the elastic block 82 pushes the insertion block 81 into the anti-fall hole under the restoring force, temporarily restricting the lamp holder 2 from falling further. This prevents the staff from being injured by the falling lighting lamp 1 when disassembling the lighting lamp 1 and turning the first bidirectional screw 52. Finally, the staff manually pulls the lamp holder 2, and the anti-fall hole and the insertion block 81 squeeze each other, causing the insertion block 81 to move out of the anti-fall hole, completing the disassembly of the lighting lamp 1.

[0027] Specifically, to facilitate the fixing of the lamp holder 2: the bottom end of the lamp 1 is fixedly connected to the top end of the lamp holder 2, and the outer walls at both ends of the lamp holder 2 are respectively provided with fixing holes for inserting the active fixing component 5 and the passive fixing component 6. The first clamp 51 and the second clamp 61 are respectively inserted into the fixing holes at both ends of the lamp holder 2 to restrict the movement of the lamp holder 2, thus achieving stable installation of the elongated lamp 1. The lamp 1 and the lamp holder 2 are existing elongated lighting fixtures, with four fixing holes located on both sides of the lamp holder 2. The size of the fixing holes is adapted to the size of the first clamp 51 and the second clamp 61.

[0028] Specifically, to facilitate the installation of the lamp holder 2: the bottom end of the mounting frame 3 is fixedly connected to the top end of the fixing plate 4, and the outer walls at both ends of the mounting frame 3 are respectively provided with insertion holes for the active fixing component 5 and the passive fixing component 6 to pass through. The mounting frame 3 wraps around the lamp holder 2 to position the lamp holder 2, and the insertion holes facilitate the insertion of the first clamp 51 and the second clamp 61. The mounting frame 3 and the fixing plate 4 are welded together, and the fixing plate 4 is fixedly connected to the elevator ceiling with bolts. The dimensions of the mounting frame 3 are adapted to the dimensions of the lamp holder 2, and the dimensions of the insertion holes are the same as the dimensions of the fixing holes.

[0029] Specifically, to facilitate fixing one end of the lamp holder 2: the active fixing component 5 includes first grippers 51 symmetrically arranged on both sides of one end of the mounting frame 3 for gripping one end of the lamp holder 2; a first bidirectional screw 52 inserted through one end of the first grippers 51 for driving the first grippers 51 to move; a first fixing rod 53 inserted through one end of the first grippers 51 for limiting the rotation of the first grippers 51; a first protective cover 54 fixedly connected to the top of the fixing plate 4 for mounting the first bidirectional screw 52 and the first fixing rod 53; and a first bevel gear 55 disposed at one end of the first bidirectional screw 52 for cooperating with the linkage 7. By rotating the first bidirectional screw 52, ​​the symmetrically arranged first grippers 51 are driven to move towards or away from each other, thereby allowing the first grippers 51 to be inserted into the fixing holes to fix one end of the lamp holder 2. The first protective cover 54 is welded and fixed to the contact part with the fixing plate 4. The two sides of the inner wall of the first protective cover 54 are welded and fixed to the two ends of the first fixing rod 53 respectively. The two sides of the inner wall of the first protective cover 54 are respectively provided with first round holes. The bearings are installed inside the first round holes and are sleeved on the outer wall of the first bidirectional screw 52. The horizontal cross section of the first gripper 51 is L-shaped. The first gripper 51 located inside the first protective cover 54 is respectively provided with a first threaded hole and a first limiting hole. The first threaded hole is threaded through the first bidirectional screw 52, ​​and the first limiting hole is threaded through the first fixing rod 53. The first bevel gear 55 is provided at the end of the first bidirectional screw 52 that extends out of the first protective cover 54. The contact part of the first bevel gear 55 with the first bidirectional screw 52 is welded and fixed.

[0030] More specifically, to facilitate fixing the other end of the lamp holder 2: the passive fixing component 6 includes second clamping claws 61 symmetrically arranged on both sides of the other end of the mounting frame 3 for gripping the other end of the lamp holder 2; a second bidirectional screw 62 inserted through one end of the second clamping claws 61 for driving the movement of the second clamping claws 61; a second fixing rod 63 inserted through one end of the second clamping claws 61 for limiting the rotation of the second clamping claws 61; a second protective cover 64 fixedly connected to the top of the fixing plate 4 for mounting the second bidirectional screw 62 and the second fixing rod 63; and a second bevel gear 65 disposed at one end of the second bidirectional screw 62 for cooperating with the linkage 7. By rotating the second bidirectional screw 62, the symmetrically arranged second clamping claws 61 are driven to move towards or away from each other, thereby allowing the second clamping claws 61 to be inserted into the fixing holes to fix the other end of the lamp holder 2. The second protective cover 64 is welded and fixed to the contact part with the fixed plate 4. The two sides of the inner wall of the second protective cover 64 are welded and fixed to the two ends of the second fixed rod 63 respectively. The two sides of the inner wall of the second protective cover 64 are respectively provided with second circular holes. The bearings are installed inside the second circular holes and are sleeved on the outer wall of the second bidirectional screw 62. The horizontal cross section of the second gripper 61 is L-shaped. The second threaded hole and the second limiting hole are respectively provided at the end of the second gripper 61 located inside the second protective cover 64. The second threaded hole is threaded through the second bidirectional screw 62, and the second limiting hole is threaded through the second fixed rod 63. The second bevel gear 65 is set at the end of the second bidirectional screw 62 that extends out of the second protective cover 64. The contact part of the second bevel gear 65 and the second bidirectional screw 62 is welded and fixed. The shape and size of the second gripper 61 and the first gripper 51 are the same. The specifications of the second bidirectional screw 62 and the first bidirectional screw 52 are the same. The specifications of the first bevel gear 55 and the second bevel gear 65 are the same.

[0031] Furthermore, to ensure the synchronous movement of the first gripper 51 and the second gripper 61, the linkage 7 includes a third bevel gear 71 disposed at the top of the fixed plate 4 for meshing with the first bevel gear 55, a fourth bevel gear 72 disposed at the top of the fixed plate 4 for meshing with the second bevel gear 65, and a connecting rod 73 fixedly connected between the third bevel gear 71 and the fourth bevel gear 72 for linkage between the two gears. The first bevel gear 55 drives the third bevel gear 71 to rotate, and the third bevel gear 71 drives the fourth bevel gear 72 to rotate via the connecting rod 73, thereby driving the second bevel gear 65 to rotate, thus achieving the synchronous movement of the first gripper 51 and the second gripper 61. The third bevel gear 71 and the fourth bevel gear 72 are of the same specifications. The two ends of the connecting rod 73 are welded and fixed to the opposite side of the third bevel gear 71 and the fourth bevel gear 72, respectively. The third bevel gear 71 and the first bevel gear 55 mesh with each other, and the fourth bevel gear 72 and the second bevel gear 65 mesh with each other. The top of the fixing plate 4 is welded with multiple fixing brackets for supporting the connecting rod 73, which restricts the connecting rod 73 to rotate while maintaining the meshing of the third bevel gear 71 with the first bevel gear 55 and the fourth bevel gear 72 with the second bevel gear 65.

[0032] Specifically, to prevent the lamp 1 from falling: the mounting frame 3 is provided with a fall arrestor 8 on the side facing the lamp holder 2 to prevent the lamp holder 2 from falling. The outer wall of the lamp holder 2 has a fall arrestor hole for inserting the fall arrestor 8. The interior of the mounting frame 3 has a cavity for installing the fall arrestor 8, and the inner wall of the cavity has a through hole. The fall arrestor 8 includes a plug 81 inserted into the through hole for insertion into the fall arrestor hole, an elastic block 82 disposed at one end of the plug 81 for pushing the plug 81, and a limiting plate 83 disposed between the plug 81 and the elastic block 82 for limiting the movement of the plug 81. When the first gripper 51 and the second gripper 61 move away from the fixing hole, the lighting lamp 1 and the lamp holder 2 fall under their own weight. When the anti-fall hole moves to the position of the insert block 81, the insert block 81 is inserted into the anti-fall hole under the restoring force of the elastic block 82, which restricts the continued movement of the lamp holder 2, thereby preventing the staff from being injured. The staff can then apply further external force to pull the lamp holder 2, and the lamp holder 2 can be disassembled. Multiple fall arrestors 8 are provided, and the position and number of fall arrestors correspond to the position and number of fall arrestors 8. The fall arrestors are adapted to the inserts 81, and the inserts 81 are welded and fixed to the limiting plate 83. The limiting plate 83 is larger than the through hole. The limiting plate 83 and the elastic block 82 are both set in the cavity. The elastic block 82 is always in a compressed state in the cavity. The vertical cross section of the insert 81 is an isosceles triangle, and the shape of the fall arrestors corresponds to the insert 81. When the first gripper 51 and the second gripper 61 are inserted into the fixing hole, the insert 81 is squeezed by the outer wall of the lamp holder 2, and the fall arrestors and the insert 81 are at different heights. When the first gripper 51 and the second gripper 61 are removed from the fixing hole, the lamp holder 2 is in Under its own force, when the anti-fall hole and the insert 81 are at the same height, the elastic block 82 causes the insert 81 to be fully inserted into the anti-fall hole, thereby limiting the further fall of the lamp holder 2. At the same time, part of the lamp holder 2 is moved out of the mounting frame 3 for easy access by the worker. After the worker has finished operating the first bidirectional screw 52, ​​by holding the part of the lamp holder 2 that protrudes from the mounting frame 3, further external force is applied, causing the inner wall of the anti-fall hole to be squeezed against the inner wall of the insert 81, thus moving the insert 81 out of the anti-fall hole and completing the disassembly and separation of the lamp holder 2 from the mounting frame 3. In this way, when operating the first bidirectional screw 52, ​​the lamp 1 can be prevented from falling and injuring the worker.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
