[0002] The setting out of isolated footings and lower column piers is an important task in building construction. Especially for the setting out of isolated footing foundations and lower column piers with relatively high depths, it has a certain degree of difficulty.

[0003] At present, there are many forms of plumb bob devices in the prior art, each having certain advantages and disadvantages. For example, patent CN221198435U discloses a plumb bob device for building construction, which includes a support, a telescopic rod is fixedly installed on the top of the support, a fixed disk is fixedly connected to the telescopic end of the telescopic rod, a rotating rod is rotatably connected to the top of the fixed disk, an adjusting component is arranged inside one end of the rotating rod, a plumb bob box is arranged at the other end of the rotating rod, and a suspension line is arranged inside the plumb bob box; the utility model is convenient for detecting some walls that do not allow nailing, will not cause damage to the wall surface, does not require workers to hold the device or find other auxiliary tools to fix the device, is relatively convenient to use, and is convenient for adjusting the height and position of the plumb bob box. When detecting multiple walls or multiple different positions on the same wall, compared with the traditional method of fixing the plumb bob box on the wall for detection, this solution does not require repeated disassembly and fixing of the plumb bob box, and can improve work efficiency.

[0004] It can be telescoped and moved, which is convenient to use, but its portability is not enough and its folding degree is relatively low. Content of the Utility Model

[0005] The utility model provides a portable retractable plumb bob vehicle, which can solve the problems pointed out in the background art.

[0006] The portable retractable plumb bob vehicle includes a height telescopic frame, a folding base, a suspension line, a plumb bob and a damper pulley. The height telescopic frame is connected to the folding base. The folding base includes folding frames on both sides. The folding frames on both sides are hingedly connected to both sides of the height telescopic frame so that it can be folded. The damper pulley is connected to the height telescopic frame, and the damper pulley is connected to the suspension line to control the height of the plumb bob.

[0007] Preferably, the folding frames on both sides are hingedly connected to both sides of the height telescopic frame through hinges.

[0008] Preferably, the height telescopic frame includes telescopic rods on both sides and a connecting rod connected between the tops of the telescopic rods on both sides. The damper pulley is connected to the connecting rod.

[0009] Preferably, the damper pulley includes a fixed sleeve, a rope pulley and a rope pulley fixing member, which is fixed on the connecting rod through the fixed sleeve. The rope pulley is rotatably connected to the fixed sleeve, and the rope pulley fixing member is used for fixing and locking the rope pulley.

[0010] Preferably, the rope pulley fixing member is a tightening screw, which is connected to the fixing plate.

[0011] Preferably, a plurality of universal wheels are provided under the folding base.

[0012] Beneficial effects: The portable telescopic plumb line vehicle provided by the present invention has the advantages of simple structure, convenient use, convenient movement and adjustment, etc. It can be telescoped and folded into a relatively small volume as much as possible, and has a high degree of portability.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following will describe in detail a specific embodiment of the present invention with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0019] Embodiment 1:

[0020] As Figures 1-3 shown, the portable telescopic plumb line vehicle provided by the embodiment of the present invention includes a height telescopic frame 1, a folding base 2, a suspension line 3, a plumb bob 4 and a damper pulley 5. The height telescopic frame 1 is connected to the folding base 2. The folding base 2 includes folding frames 21 on both sides. The folding frames 21 on both sides are hinged to both sides of the height telescopic frame 1 so that they can be folded. The damper pulley 5 is connected to the height telescopic frame 1, and the damper pulley 5 is connected to the suspension line 3 to control the height of the plumb bob 4.

[0021] Specifically, the folding frames 21 on both sides are hingedly connected to both sides of the height telescopic frame 1 through hinges 6. The height telescopic frame 1 includes telescopic rods 11 on both sides and a connecting rod 12 connected between the tops of the telescopic rods 11 on both sides. The damper pulley 5 is connected to the connecting rod 12.

[0022] Specifically, the damper pulley 5 includes a fixed sleeve 51, a rope pulley 52, and a rope pulley fixing member 53. It is fixed to the connecting rod 12 through the fixed sleeve 51. The rope pulley 52 is rotatably connected to the fixed sleeve 51. The rope pulley fixing member 53 is used for fixing and locking the rope pulley 52. The rope pulley fixing member 53 is a tightening screw, which is connected to the fixing plate 54. By screwing the tightening screw inward to tighten the rope pulley 52, the fixing of the rope pulley 52 can be achieved, that is, the locking of the position of the plumb bob 4.

[0023] In some embodiments, a plurality of universal wheels 7 are provided under the folding base 2.

[0024] The above-disclosed are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
