the embodiment of the invention provides a portable house detection device for real estate assessment, as shown in figures 1-7, comprising a bottom plate 1, universal wheels 101 are fixedly installed at four corners of the bottom plate 1, two groups of support columns 2 are fixedly connected to the top of the bottom plate 1, a top plate 3 is fixedly connected to the tops of the support columns 2, lifting slide blocks 4 are slidably connected to the two groups of support columns 2, round holes corresponding to the support columns 2 are formed in the lifting slide blocks 4, a clamping mechanism is arranged on the lifting slide blocks 4, lifting plates 5 are fixedly connected to the side walls of the lifting slide blocks 4, first hollow cylinders 6 are fixedly connected to the tops of the lifting plates 5, the tops of the first hollow cylinders 6 penetrate through the top plate 3 and extend upwards, round holes corresponding to the first hollow cylinders 6 are formed in the top plate 3, inner cavities are formed in the axes of the first hollow cylinders 6, second hollow cylinders 9 are movably inserted in, an inner cavity is arranged inside the second hollow cylinder 9, a third hollow cylinder 10 is movably inserted in the inner cavity, a clamping mechanism corresponding to the second hollow cylinder 9 is arranged on the first hollow cylinder 6, a clamping mechanism corresponding to the third hollow cylinder 10 is arranged on the second hollow cylinder 9, the two groups of clamping mechanisms are identical in structure, a supporting platform 11 is fixedly connected to the top of the third hollow cylinder 10, a shaft seat 12 is fixedly connected to the top of the supporting platform 11, a rotating rod 13 is rotatably connected to the shaft seat 12, an angle adjusting mechanism corresponding to the rotating rod 13 is arranged at the bottom of the supporting platform 11, a fixed pulley 14 is fixedly arranged at the top of the rotating rod 13, two groups of standing plates 18 are fixedly connected to the top of the bottom plate 1, a roller 19 is rotatably connected to the standing plates 18, a locking mechanism corresponding to the roller 19 is arranged on the standing plates 18, a connecting rope 16 is wound on the roller 19, a limiting sleeve 17 is fixedly connected to the top of the top plate 3, the top of the connecting rope 16 passes through the limiting sleeve, when the user uses, the angle to bull stick 13 that can be quick is adjusted through the angle adjustment mechanism who sets up, consequently, make bull stick 13 and wall laminate more, in actual operation, often probably meet the phenomenon of opposite sex wall body, therefore, if the angle of bull stick 13 is fixed, then under a large number of circumstances, bull stick 13 can not guarantee fixed pulley 14 and wall laminating, just so lead to measuring accuracy's reduction, can laminate more with the wall in order to guarantee fixed pulley 14, it is adjustable to set up bull stick 13 angle, consequently, guarantee the practicality of device main part when measuring, make measured data more accurate, guarantee house detection effect.

The angle adjusting mechanism comprises a bearing 20, the bearing 20 is fixedly connected to the bottom of the supporting platform 11, a lead screw 21 is rotatably connected to the axis of the bearing 20, a handle is fixedly connected to the bottom of the lead screw 21, a nut sleeve 22 is sleeved on the lead screw 21, the nut sleeve 22 is in threaded connection with the lead screw 21, the angle adjusting mechanism is simple in structure and not easy to damage, and can ensure that the fixed pulley 14 is kept attached to the top of a wall body, when the angle of the rotating rod 13 is adjusted, for example, the angle is adjusted upwards, the lead screw 21 is directly rotated, after the lead screw 21 is rotated, the lead screw 21 rotates along the bearing 20, the nut sleeve 22 is driven to move upwards by the lead screw 21 when rotating, the nut sleeve 22 drives the lifting block 23 to move upwards, the lifting block 23 drives the U-shaped rod 24 to slide upwards along the square groove 1101, the U-shaped rod 24 further drives the top cross rod of the U-shaped rod 24 to, the rotating rod 13 drives the fixed pulley 14 to rotate, so that the angle of the rotating rod 13 is adjusted upwards, and when the angle of the rotating rod is required to be adjusted downwards, the opposite direction to the adjusting process is achieved, namely the screw rod 21 is rotated reversely.

The outer side of the nut sleeve 22 is fixedly connected with an elevating block 23, the top of the elevating block 23 is fixedly connected with a U-shaped rod 24, the U-shaped rod 24 is U-shaped, the U-shaped opening of the U-shaped rod 24 faces downwards, the top of the U-shaped rod 24 penetrates through the supporting platform 11 and extends upwards, and the U-shaped rod 24 provides support for the rotating rod 13.

The supporting platform 11 is provided with a square groove 1101 corresponding to the U-shaped rod 24, the side wall of the rotating rod 13 is provided with a sliding groove 1302, the top cross rod of the U-shaped rod 24 is slidably connected in the sliding groove 1302, and the U-shaped rod 24 can be guaranteed to be limited through the square groove 1101 arranged, so that the U-shaped rod 24 can only move in the vertical direction.

When the user uses, the angle to bull stick 13 that can be quick is adjusted through the angle adjustment mechanism who sets up, consequently, make bull stick 13 and wall laminate more, in actual operation, often probably meet the phenomenon of opposite sex wall body, therefore, if the angle of bull stick 13 is fixed, then under a large number of circumstances, bull stick 13 can not guarantee fixed pulley 14 and wall laminating, just so lead to measuring accuracy's reduction, can laminate more with the wall in order to guarantee fixed pulley 14, it is adjustable to set up bull stick 13 angle, consequently, guarantee the practicality of device main part when measuring, make measured data more accurate, guarantee house detection effect.

When the angle of the rotating rod 13 is adjusted, for example, the angle is adjusted upwards, the screw rod 21 is directly rotated, after the screw rod 21 is rotated, the screw rod 21 rotates along the bearing 20, the screw rod 21 drives the nut sleeve 22 to move upwards when rotating, the nut sleeve 22 drives the lifting block 23 to move upwards, the lifting block 23 drives the U-shaped rod 24 to slide upwards along the square groove 1101, the U-shaped rod 24 further drives the top cross rod of the U-shaped rod 24 to slide in the sliding groove 1302, at this time, the U-shaped rod 24 drives the rotating rod 13 to rotate along the pin roll 1301, the rotating rod 13 drives the fixed pulley 14 to rotate, at this time, the angle of the rotating rod 13 is adjusted upwards, when the angle needs to be adjusted downwards, the opposite direction to the adjusting process is achieved, namely, the screw rod 21 is rotated reversely.
