Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a quick leveling device for building door and window installation, including a protective shell 1 and a leveling mechanism 3. A rotating handle 2 is arranged on the outer side of the left side of the protective shell 1, a leveling mechanism 3 is arranged inside the protective shell 1, a threaded rod 301 is clamped inside the protective shell 1, a chuck 302 is threadedly connected to the outer side of one end of the threaded rod 301, a connecting column 306 is arranged on one side of the chuck 302, and the connecting column 306 is fixedly connected to the threaded rod 301.

[0025] Specifically, bearings 303 are provided on the right side of the chuck 302. The bearings 303 are sleeved on the connecting columns 306. There are two sets of bearings 303, and every two sets of bearings 303 correspond to one set of connecting columns 306. The chuck 302 can keep the threaded rod 301 at fixed positions at the upper and lower ends of the protective shell 1 when it rotates, making the rotation of the threaded rod 301 more stable. On the one hand, the sleeving of the bearings 303 on the connecting columns 306 can keep the connecting columns 306 at fixed positions when they rotate, playing a limiting role. On the other hand, it can also reduce the friction when the connecting columns 306 rotate, making the device more labor-saving to use.

[0026] Specifically, a limiting disc 304 is provided at one end of the bearing 303. The limiting disc 304 is fixedly connected to the protective shell 1. There are three sets of limiting discs 304. The limiting discs 304 can play a limiting role on the bearings 303, making the overall structure more stable.

[0027] Specifically, a gear 305 is fixedly connected to one end of the connecting column 306. The connecting columns 306 and the gears 305 are arranged in one-to-one correspondence. Through the setting of the gears 305, when the middle gear 305 rotates, the two sets of gears 305 engaged with it rotate in opposite directions, thereby controlling the vertical movement of the support arm 309.

[0028] Specifically, two sets of limit nuts 307 are threadedly connected to the other end of the threaded rod 301, which can prevent the support arm 309 from moving out of the working range.

[0029] Specifically, a shaft disc 308 is fixedly connected to the right side of the protective shell 1. A gauge limit shaft 311 is threadedly connected to the shaft disc 308. The support arm 309 is sleeved on the gauge limit shaft 311. The support arm 309 is made of steel. Passing two gauge limit shafts 311 through the support arm 309 and threadedly connecting them to the shaft disc 308 can make the support arm 309 of the device keep a vertical movement direction when moving vertically.

[0030] Specifically, the support arm 309 is threadedly connected to the threaded rod 301. One end of the support arm 309 is fixedly connected with a plug 310. The support arm 309 is in the shape of a "Z", which can play a role in supporting the doors and windows for height adjustment.

[0031] Working principle: First, thread two support arms 309 onto the threaded rod 301. Subsequently, thread the limit nuts 307 onto both ends of the threaded rod 301 to limit the movement range of the two support arms 309 and ensure safety. Then, pass two gauge limit shafts 311 through the two support arms 309 and thread them onto the shaft disc 308 to prevent the two support arms 309 from moving laterally. In the second step, insert the insertion block 310 into the gap under the window. In the third step, by rotating the rotating handle 2, the connecting column 306 inside the protective shell 1 rotates, driving the gear 305 to rotate. Through the mutual cooperation of the gears 305, finally, the two threaded rods 301 rotate in different directions, driving the distance between the support arms 309 on the threaded rods 301 to expand. Finally, observe the scale on the gauge limit shaft 311 and make precise fine-tuning for comparing and leveling the height of the window on the insertion block 310.

[0032] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics known in the solutions is not described in detail here. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
