[0002] Elevator maintenance is an important link to ensure the safe and reliable operation of elevators. It covers aspects such as preventive maintenance, fault repair, regular inspection, and component replacement. When maintaining an elevator, the lighting device is very crucial. It ensures that maintenance personnel have sufficient visibility when working in areas such as elevator hoistways, carriages, and machine rooms, thereby improving work efficiency and ensuring operation safety.

[0003] Elevator maintenance operations are usually carried out in a relatively enclosed and poorly lit environment, such as elevator hoistways, machine rooms, or inside carriages. In such an environment, high-quality lighting is the basis for ensuring efficient, accurate, and safe maintenance work. Currently, the common lighting method for elevator maintenance personnel is usually to wear a headlamp to achieve the lighting effect. However, the lighting range of the headlamp is small and the light intensity is insufficient, which cannot meet the demand for sufficient lighting during elevator repair and inspection.

[0004] Therefore, we need to design a lighting device for elevator maintenance. Content of the Utility Model

[0005] In order to overcome the drawback that the lighting range of the headlamp worn by elevator repairmen is limited, which reduces work efficiency, the utility model provides a lighting device for elevator maintenance.

[0006] The technical solution is: A lighting device for elevator maintenance includes a knob, a bidirectional screw, an installation frame, clamping blocks, a telescopic rod, a motor, a sleeve, a lead screw, a moving block, an adjusting block, and a lighting lamp. The knob is connected to the bidirectional screw. The installation frame is arranged outside the bidirectional screw. The front and rear sides of the installation frame are threadedly connected with clamping blocks. The right side of the installation frame is fixedly connected with a telescopic rod. The right side of the telescopic rod is fixedly connected with a sleeve. A motor is provided at the front end of the right part of the telescopic rod. The output shaft of the motor is fixedly connected with a lead screw. The moving block is slidably connected inside the sleeve. The moving block is located outside the lead screw, and the moving block is in threaded cooperation with the lead screw. The rear part of the moving block is rotatably connected with an adjusting block. The rear side of the adjusting block is fixedly connected with a lighting lamp.

[0007] Furthermore, it further includes rubber pads. Rubber pads are provided on the mutually approaching sides of the two clamping blocks.

[0008] Furthermore, it further includes a controller. The controller is provided at the top of the right side of the telescopic rod. The controller is electrically connected to the control motor and the lighting lamp.

[0009] Furthermore, it further includes a detent ball. The controller is provided at the top of the right side of the telescopic rod. The controller is electrically connected to the control motor and the lighting lamp.

[0010] Furthermore, a number of clamping grooves are circumferentially provided on both the left and right sides of the rear part inside the moving block, and the clamping grooves are adapted to the clamping beads.

[0011] Furthermore, it further includes a bolt, and the bolt is inserted into the front side inside the telescopic rod.

[0012] Furthermore, a number of jacks are provided on the front side inside the telescopic rod, and the bolt is inserted into the jacks.

[0013] Furthermore, it further includes a spring. Springs are provided between the clamping beads on both the left and right sides and the adjusting block, and the springs are made of strong elastic material.

[0014] Compared with the prior art, the utility model has the following advantages: 1. The utility model achieves the fixing effect through the threaded connection between the bidirectional screw rod and the clamping block, which is extremely practical for elevators.

[0025] The present utility model will be specifically described below with reference to the accompanying drawings.

[0026] Embodiment: A lighting device for elevator maintenance, as Figures 1-6 shown, comprising a knob 1, a bi-directional screw 2, a mounting frame 201, a clamping block 3, a telescopic rod 5, a motor 8, a sleeve 9, a lead screw 10, a moving block 11, an adjusting block 12 and a lighting lamp 16. The knob 1 is connected with the bi-directional screw 2. The mounting frame 201 is arranged outside the bi-directional screw 2. The front and rear sides of the mounting frame 201 are threadedly connected with the clamping blocks 3. The right side of the mounting frame 201 is fixedly connected with the telescopic rod 5. The right side of the telescopic rod 5 is fixedly connected with the sleeve 9. The front end of the right part of the telescopic rod 5 is provided with the motor 8. The output shaft of the motor 8 is fixedly connected with the lead screw 10. The inner side of the sleeve 9 is slidably connected with the moving block 11. The moving block 11 is located outside the lead screw 10, and the moving block 11 is in threaded cooperation with the lead screw 10. The rear part of the moving block 11 is rotatably connected with the adjusting block 12. The rear side of the adjusting block 12 is fixedly connected with the lighting lamp 16.

[0027] As Figures 1-3 shown, it further comprises a rubber pad 4. Rubber pads 4 are arranged on the mutually approaching sides of the two clamping blocks 3. The rubber pads 4 are adhesively connected to the clamping blocks, which can reduce the damage to the elevator door when the device is fixedly clamped, and at the same time can increase the friction force between the clamping block and the elevator door to prevent the device from slipping.

[0028] As Figure 1 shown, it further comprises a controller 17. The controller 17 is arranged at the top of the right side of the telescopic rod 5. The controller 17 is electrically connected to the control motor 8 and the lighting lamp 16, which facilitates the elevator maintenance personnel to operate the device.

[0029] As Figures 1-7 shown, it further comprises balls 13. The left and right sides inside the adjusting block 12 are slidably provided with the balls 13. The two balls 13 are in sliding contact with the rotational connection parts on the two sides of the adjusting block 12 and the moving block 11. A plurality of card slots 15 are circumferentially arranged on the left and right sides of the inner rear part of the moving block 11. The card slots 15 are adapted to the balls 13. In this way, the lighting range of the lighting lamp 16 can be adjusted.

[0030] As Figure 7As shown, it further includes a bolt 6. The bolt 6 is inserted into the front side of the telescopic rod 5. A plurality of jacks 7 are provided on the front side inside the telescopic rod 5, and the bolt 6 is inserted into the jack 7, so as to adjust the length of the telescopic rod 5 of the device to be applicable to more scenarios.

[0031] As Figure 7 shown, it further includes a spring 14. Springs 14 are provided between the catch beads 13 on the left and right sides and the adjustment block 12. The spring 14 is made of a strong elastic material. Therefore, when rotating the illumination range of the lighting lamp 16, it can be rotated flexibly, and at the same time, the service life of the device is extended.

[0032] Before using this device, the elevator maintainer should first ensure that the clamping blocks 3 at both ends of the device are located on both sides of the bidirectional screw 2. When elevator maintenance is required, first align the gap of the clamping block 3 with the side of the elevator door, and then push it inward to a suitable position. Manually rotate the knob 1 clockwise, and the bidirectional screw 2 drives the clamping blocks 3 to move from both sides to the middle until the rubber pads 4 on the sides where the clamping blocks 3 approach each other are completely attached to the elevator door to fix the device. The rubber pads 4 can increase the friction of the object contact surface so that the device can be more stably fixed to the side of the elevator door, and the elevator maintainer can then stop rotating the knob 1. After the elevator maintainer fixes the device, the elevator maintainer can first control the lighting of the lighting lamp 16 through the controller 17, and then adjust the positions of the telescopic rod 5 and the moving block 11 according to the position of the elevator repair. After pulling out the pin 6 from the jack 7, the length of the telescopic rod 5 can be adjusted. If it is necessary to lengthen the telescopic rod 5, just hold the sleeve 9 and pull it to the right. After aligning the inner and outer holes of the telescopic rod 5, insert the pin 6 into the hole and fix the pin 6 to achieve the purpose of lengthening the telescopic rod 5. If it is necessary to shorten the telescopic rod 5, just pull the sleeve 9 to the left and then fix the pin 6 to achieve the purpose of adjusting the length of the telescopic rod 5. The length of the sleeve 9 can be adjusted by controlling the motor 8 through the controller 17. The output shaft of the motor 8 drives the lead screw 10 to rotate. The lead screw 10 and the moving block 11 are connected in a threaded manner. When the moving block 11 extends to a suitable length, the motor 8 can be controlled to turn off through the controller 17, and the moving block 11 stops rotating. After fixing the height and approximate position of the lighting lamp 16, the lighting range of the lighting lamp 16 can also be adjusted through the adjusting block 12. Since the adjusting block 12 is fixedly connected to the rear of the lighting lamp 16, the lighting lamp 16 can be directly held on the side and then rotated. The adjusting block 12 is provided with beads 13 and springs 14 on the left and right sides that are clamped with the card slots 15. During the rotation process, the spring 14 is compressed, the length of the spring 14 becomes shorter, the bead 13 moves from the original card slot 15 to another card slot 15, and then the spring 14 returns to its original position, and the bead 13 is clamped in another card slot 15. When the lighting lamp 16 rotates to a suitable angle, it can stop rotating. When the elevator maintainer finishes using the device, just control the lighting lamp 16 to turn off through the controller 17, then restore the telescopic rod 5 and the sleeve 9, and finally rotate the knob 1 counterclockwise to drive the bidirectional screw 2 to rotate until the clamping block 3 slowly loosens and then remove the device.

[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
