[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] In order to solve the problems of single opening angle of the support legs, the support legs can only be used on flat roads, and lack of flexibility, please refer to Figures 1-4 , an embodiment provided by the present utility model is as follows:

[0022] A support device for building surveying, comprising an installation platform 1, main support legs 2 and auxiliary support legs 3. The main support legs 2 and the auxiliary support legs 3 are both located below the installation platform 1. There are at least two auxiliary support legs 3, and the main support leg 2 is located on one side of the two auxiliary support legs 3. A single main support leg 2 and the two auxiliary support legs 3 are in three-point contact with the ground, so that the installation platform 1, the single main support leg 2 and the two auxiliary support legs 3 can form a firm and stable structure, avoiding the situation of the installation platform 1 shaking.

[0023] The auxiliary support leg 3 includes a second support rod 301, a second limit post 306, a second support 305 and an adapter 303. The main support leg 2 includes a first support rod 201, a first limit post 204, a first transmission rod 207 and a first support 206. A first U-shaped seat 202 and a second U-shaped seat 302 are arranged under the installation platform 1. A turntable 308 is arranged on one side of the second U-shaped seat 302.

[0024] The upper end of the first support rod 201 is axially connected to the first U-shaped seat 202. A fixing plate 208 is arranged on one side of the first U-shaped seat 202. A first guide shaft 203 is arranged on the side surface of the first support rod 201. The first support 206 is sleeved on the first guide shaft 203. One side of the first support 206 is axially connected to the lower end of the first transmission rod 207. A first positioning seat 2061 is arranged on the other side of the first support 206. The upper end of the first transmission rod 207 is axially connected to the fixing plate 208. The first support 206 can slide on the first guide shaft 203. As the first support 206 slides, the opening angle of the first transmission rod 207 changes, thereby driving the opening angle of the main support leg 2 to change. The first positioning seat 2061 can fix the position of the first support 206. When the position of the first support 206 is fixed, the position of the first transmission rod 207 is also fixed, so that the opening angle of the main support leg 2 is fixed.

[0025] The upper end of the adapter 303 is axially connected to the second U-shaped seat 302, and the lower end of the adapter 303 is axially connected to the upper end of the second support rod 301. There are at least two turntables 308, and both turntables 308 are axially connected to the second U-shaped seat 302. A second transmission rod 309 is arranged on one side of the second support rod 301, and a second guide shaft 304 is arranged on the side surface of the second support rod 301. The second support 305 is sleeved on the second guide shaft 304. One side of the second support 305 is axially connected to the lower end of the second transmission rod 309. A second positioning seat 3051 is arranged on the other side of the second support 305. The upper end of the second transmission rod 309 is axially connected to the turntable 308. The second support 305 can slide on the second guide shaft 304. As the second support 305 slides, the opening angle of the second transmission rod 309 changes, thereby driving the opening angle of the secondary support leg 3 to change. The second positioning seat 3051 can fix the position of the second support 305. When the position of the second support 305 is fixed, the position of the second transmission rod 309 is also fixed, so that the opening angle of the secondary support leg 3 is fixed, thereby controlling the opening and closing of the secondary support leg 3.

[0026] The main support leg 2 rotates longitudinally with the first U-shaped seat 202 as the center, and the two secondary support legs 3 respectively rotate transversely with the second U-shaped seat 302 as the center. At the same time, the two secondary support legs 3 also have the ability to rotate longitudinally with the adapter 303 as the center. Compared with the traditional support legs that can only rotate in a fixed direction, the ability of the main support leg 2 and the two secondary support legs 3 to support stably on uneven roads is improved, the flexibility during use is improved, and the practicality is further improved.

[0027] The second limiting post 306 is a hollow cylindrical structure. The second limiting post 306 is sleeved on the lower end of the second support rod 301. The second limiting post 306 is connected to the second support rod 301 through the second threaded wall 307. A second tip 3061 is arranged at the lower end of the second limiting post 306. The first limiting post 204 is a hollow cylindrical structure. The first limiting post 204 is sleeved on the lower end of the first support rod 201. The first limiting post 204 is connected to the first support rod 201 through the first threaded wall 205. A first tip 2041 is arranged at the lower end of the first limiting post 204.

[0028] The first positioning seat 2061 includes a rotatable disc and a screw. The screw inside the first positioning seat 2061 is threadedly connected to the first support 206. The second positioning seat 3051 includes a rotatable disc and a screw. The screw inside the second positioning seat 3051 is threadedly connected to the second support 305. When the main support leg 2 and the two sub-support legs 3 are both rotated to appropriate positions and the first tip 2041 and the second tip 3061 touch the ground, the discs of the first positioning seat 2061 and the second positioning seat 3051 can be respectively twisted, so that the screws in the first positioning seat 2061 and the second positioning seat 3051 respectively press the first guide shaft 203 and the second guide shaft 304, thereby fixing the first transmission rod 207 and the second transmission rod 309, and further fixing the positions of the main support leg 2 and the two sub-support legs 3, further improving the stability of the main support leg 2 and the two sub-support legs 3 during use; when the position of the mounting platform 1 needs to be raised, the first limit post 204 and the second limit post 306 can be twisted, so that the first limit post 204 and the second limit post 306 descend, thereby extending the main support leg 2 and the sub-support legs 3, and further raising the position of the mounting platform 1, further improving the applicability of the mounting platform 1 during use.

[0029] Working principle: When the main support leg 2 and the two sub-support legs 3 are both rotated to appropriate positions and the first tip 2041 and the second tip 3061 touch the ground, the positions of the main support leg 2 and the two sub-support legs 3 can be fixed by respectively twisting the discs of the first positioning seat 2061 and the second positioning seat 3051; when the position of the mounting platform 1 needs to be raised, the first limit post 204 and the second limit post 306 can be twisted, thereby extending the main support leg 2 and the sub-support legs 3, and further raising the position of the mounting platform 1, improving the flexibility of the present utility model during use.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description.
