[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present utility model and do not limit the protection scope of the present utility model.

[0024] It should be noted that when an element is referred to as being "fixed to", "arranged on", "secured to" or "mounted on" another element, it can be directly on the other element or there can be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. Further, when an element is considered to be "fixedly connected" to another element, the two can be fixed in a detachable connection manner or a non-detachable connection manner, such as sleeving, clamping, integrally formed fixing, welding, etc., which can be achieved in the prior art and will not be elaborated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is perpendicular, but due to the influence of manufacturing and assembly, there can be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the specification of this utility model herein are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The "first" and "second" involved in this utility model do not represent specific quantities and sequences, but are only used for name distinction.

[0027] Combined with the attached Figure 1 and 2 , a telescopic ceiling light box of this embodiment includes a light box 1. The upper end of the light box 1 is connected to the ceiling through a telescopic rod 2. The telescopic rod 2 is vertically arranged. The telescopic rod 2 includes a first connecting rod 21 and a second connecting rod 22 that are telescopically connected. The first connecting rod 21 and the second connecting rod 22 are coaxially arranged. The upper end of the first connecting rod 21 is fixedly connected to the ceiling through an expansion screw. The lower end of the second connecting rod 22 is fixedly connected to the light box 1. External threads are provided on the outer surfaces of the first connecting rod 21 and the second connecting rod 22. A first nut 23 is connected to the first connecting rod 21, and a second nut 24 is connected to the second connecting rod 22. The first nut 23 and the second nut 24 are fixedly connected.

[0028] The structure of this telescopic ceiling light box is simple and easy to install. After the first nut 23 and the second nut 24 are respectively screwed tightly with the first connecting rod 21 and the second connecting rod 22, the first connecting rod 21 and the second connecting rod 22 can be fixed. The length of the telescopic rod 2 can be adjusted according to actual needs, and the height of the light box 1 is adjustable, so as to meet the different lighting needs of users.

[0029] As a preferred embodiment of the present utility model, the first connecting rod 21 is movably inserted into the second connecting rod 22. The diameter of the first connecting rod 21 is smaller than that of the second connecting rod 22. An activity groove matching the first connecting rod 21 is provided in the second connecting rod 22. A limiting strip 211 is arranged on the outer surface of the first connecting rod 21 along its axial direction. A limiting groove matching the limiting strip 211 is provided on the inner surface of the second connecting rod 22. The cooperation between the limiting strip 211 and the limiting groove enables the first connecting rod 21 and the second connecting rod 22 to be axially movable relative to each other only. When the second nut 24 is tightened, the torque generated by the second connecting rod 22 will not be transmitted to the light box 1 to affect the connection strength between the second connecting rod 22 and the light box 1. The torque generated by the second connecting rod 22 will be transmitted to the first connecting rod 21 through the limiting strip 211 and finally transmitted to the connection position between the first connecting rod 21 and the suspended ceiling. Since the structure of the suspended ceiling is relatively firm, only the connection between the first connecting rod 21 and the suspended ceiling needs to be strengthened. In the case where only one telescopic rod 2 is provided on the light box 1, by using the cooperation between the limiting strip 211 and the limiting groove, the user does not need to use great force to restrict the rotation of the light box 1 when tightening the second nut 24. In this embodiment, the limiting strip 211 is arranged at the lower part of the first connecting rod 21, and external threads are arranged at the middle and upper parts.

[0030] As a preferred embodiment of the present utility model, the light box 1 is connected to the suspended ceiling through two telescopic rods 2. The light box 1 includes a split left box body 11 and right box body 12. The two telescopic rods 2 are respectively arranged on the left box body 11 and the right box body 12. The opposite sides of the left box body 11 and the right box body 12 are both open and are arranged close to each other. A sealing strip 13 is arranged around the connection position between the left box body 11 and the right box body 12 in the light box 1. The sealing strip 13 is used to seal the gap between the left box body 11 and the right box body 12. The two ends of the sealing strip 13 are respectively sealed and connected to the left box body 11 and the right box body 12. The middle of the sealing strip 13 is a flexible part. When the operator adjusts the height of the light box 1, the height of the left box body 11 and the right box body 12 can be adjusted respectively to complete the adjustment. Because when adjusting the height of the light box 1, it is necessary to manually lift the light box 1 for manual adjustment. If the weight of the light box 1 is heavy, the manual adjustment is very laborious, and it is necessary to unlock the telescopic rods 2 on both sides at the same time to start the adjustment. Therefore, in this embodiment, the light box 1 is designed into a split structure.

[0031] As a preferred embodiment of the present utility model, an infrared emitter 3 is arranged on the left box body 11, and an infrared receiver 4 is arranged on the right box body 12. Both the infrared emitter 3 and the infrared receiver 4 are arranged at the upper end of the light box 1. The infrared emitter 3 and the infrared receiver 4 are arranged opposite to each other. When the heights of the left box body 11 and the right box body 12 are adjusted to be the same, the infrared receiver 4 can receive the infrared signal from the infrared emitter 3, so as to facilitate the height adjustment of the light box 1 and ensure the aesthetic degree after the height adjustment of the light box 1.

[0032] As a preferred solution of the present utility model, a first pull rope 5 is provided on the left box body 11, and a second pull rope 6 is provided on the right box body 12. Both the first pull rope 5 and the second pull rope 6 are provided at the upper end of the light box 1. A tension sensor 7 is connected between the first pull rope 5 and the second pull rope 6. When the heights of the left box body 11 and the right box body 12 are adjusted to be the same, the first pull rope 5 and the second pull rope 6 are in a straight or nearly straight state. When there is a height difference between the left box body 11 and the right box body 12, the first pull rope 5 and the second pull rope 6 will generate tension and trigger the tension sensor 7. At this time, the tension sensor 7 can trigger the alarm to give an alarm, so as to remind the maintenance personnel that there is a risk of the light box falling at this time. In order to prevent the light box 1 from accidentally triggering the tension sensor 7 when adjusting the height, the first pull rope 5 and the second pull rope 6 are detachably connected to the tension sensor 7 by means of hooks or the like. When adjusting the height, the connection between the first pull rope 5 and the second pull rope 6 and the tension sensor 7 is released, and they can be reconnected after the height adjustment is completed.

[0033] The above has schematically described the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative efforts without departing from the creative spirit of the present utility model, they shall fall within the protection scope of the present utility model.
