In addition, all embodiments may be used in combination with each other.

[0027] See also Figures 1 to 6 , the utility model provides a technical solution:

[0028] Embodiment 1, a telescopic keel, the telescopic keel comprises: a keel body 1, an adjusting portion 2, an extending portion 3 and a reinforcing portion 4.

[0029] Specifically, the inner side of the keel body 1 is fixedly connected to two symmetrically arranged positioning blocks 5, and the inner side of the positioning block 5 is rotatably connected to the adjusting portion 2. The adjusting portion 2 includes a threaded tube 21 rotatably connected to the positioning block 5. The positioning block 5 can fix the position of the threaded tube 21 to ensure that the threaded tube 21 can only rotate. The inner side of the threaded tube 21 is fixedly connected to two convex blocks of equal length and opposite rotation directions, and both ends of the threaded tube 21 are threadedly plugged with a threaded rod 22. One end of the threaded rod 22 is rotatably connected to an extension portion 3 slidably connected to the keel body 1. The threaded rod One end of 22 is fixedly connected to a limit block 26, and the limit block 26 is rotatably connected to the extension part 3. The limit block 26 can ensure that when the threaded rod 22 slides, the extension part 3 will be driven to slide. By rotating the threaded tube 21, the threaded rod 22 can be driven to slide relative to each other, thereby driving the extension part 3 to slide, so that the device can adapt to the room size. A reinforcement part 4 is provided on one side of the keel body 1 to limit the rotation of the threaded tube 21. The reinforcement part 4 can ensure that the position of the extension part 3 will not change by limiting the rotation of the threaded tube 21 after adjusting the size of the device.

[0030] In order to facilitate the positioning block 5 to better limit the sliding of the threaded tube 21, two positioning grooves 24 for installing the positioning block 5 are opened on one side of the threaded tube 21 of the present application, and a mounting hole 51 for rotatably installing the threaded tube 21 is opened on one side of the positioning block 5. The position of the threaded tube 21 can be effectively fixed by the cooperation of the positioning block 5 and the positioning groove 24. The side of the threaded tube 21 is fixedly connected with multiple convex plates 23 distributed in a circular array, and the convex plates 23 can facilitate the control of the rotation of the threaded tube 21.

[0031] In order to provide a better supporting effect, the extension part 3 of the present application includes a mounting plate 31 which is rotatably connected to the threaded tube 21 and the limit block 26. A support plate 32 and a fixing block 33 are fixedly connected to one side of the mounting plate 31. The support plate 32 is arranged into a polygon and is rotatably connected to the threaded rod 22. One end of the fixing block 33 is flush with the end face of the keel body 1 at that location, so as to ensure that sufficient mounting surface is provided for other structures.

[0032] In order to better limit the rotation of the threaded tube 21, the reinforcement part 4 of the present application includes a control rod 41 that is slidably connected to the keel body 1. Both ends of the control rod 41 are fixedly connected with a splint 42 arranged in a "V" shape. The positions of the splint 42 and the threaded tube 21 correspond to each other, and a spring 43 is fixedly connected between the threaded tube 21 and the keel body 1. After the position of the threaded tube 21 is determined, the splint 42 is allowed to slide under the action of the spring 43 and then engage with the threaded tube 21. The friction between the splint 42 and the threaded tube 21 is used to effectively limit the rotation of the threaded tube 21. The spring 43 can ensure that the splint 42 always fits the threaded tube 21. The control rod 41 can easily control the two splints 42 to slide away from the threaded tube 21 at the same time, thereby facilitating the rotation of the threaded tube 21.

[0033] In order to further improve the limiting effect of the reinforcing part 4, the side of the splint 42 of the present application that contacts the threaded tube 21 is fixedly connected with a No. 2 rubber pad 44, and the side of the threaded tube 21 is fixedly connected with a No. 1 rubber pad 25 corresponding to the position of the No. 2 rubber pad 44. The No. 1 rubber pad 25 and the No. 2 rubber pad 44 can increase the friction between the threaded tube 21 and the splint 42, thereby better limiting the rotation of the threaded tube 21. At the same time, the No. 1 rubber pad 25 and the No. 2 rubber pad 44 can also protect the threaded tube 21 and the splint 42.

[0034] In order to facilitate the installation of the control rod 41, two symmetrically arranged connecting plates 6 are fixedly connected to one side of the keel body 1 of the present application. A socket 61 for the sliding insertion of the control rod 41 is opened on one side of the connecting plate 6. The spring 43 is located between the splint 42 and the connecting plate 6, so that the control rod 41 can be easily slidably inserted into the keel body 1.

[0035] During actual implementation, the size of the room is first determined, and then the control rod 41 is pulled to drive the clamping plate 42 to slide away from the threaded tube 21. Then, the threaded tube 21 is rotated by the convex plate 23 to cause the threaded rod 22 to drive the extension part 3 to slide until the entire device meets the room size. Then, the restraint on the control rod 41 is released, and the free clamping plate 42 is allowed to slide toward the threaded tube 21 under the action of the spring 43. Then, the rotation of the threaded tube 21 is restricted by friction, and the adjustment is completed, and the next step of installation is carried out.

[0036] The present application also discloses a ceiling quick installation structure, comprising the above-mentioned telescopic keel.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
