There are many types of levels, such as micro-tilt level, automatic leveling level, laser level, digital level, etc. When using the level to measure, it is generally necessary to set up the level on a measuring bracket;

[0003] In order to improve the stability of the existing level tripod, a pin is provided at the bottom of the leg to fix the tripod on the ground to improve the stability. However, when the pin is plugged into the ground, the tripod is limited. If the height of the level is to be adjusted at this time, the pin plugged into the ground must be pulled out to adjust the height. The overall flexibility is poor and it is inconvenient to use.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 As shown;

[0026] A level tripod for construction project management comprises a level fixing seat 1 and a support rod 2 fixed at the bottom of the level.

[0027] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "in order to improve the stability of the existing level tripod, a pin is set at the bottom of the leg to fix the tripod to the ground to improve stability. However, when the pin is plugged into the ground, the tripod is limited. If the height of the level is to be adjusted at this time, the pin plugged into the ground must be pulled out. When adjusting the height, the overall flexibility is poor and the use is inconvenient." Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a sliding component 4 is added on this basis.

[0028] like Figure 1-3 As shown in the figure;

[0029] In combination with the above content, in order to improve the flexibility of the device, it also includes a tripod retractable component 3 arranged at the bottom of the support rod 2, and three sliding components 4 arranged at the bottom of the tripod retractable component 3;

[0030] The sliding assembly 4 includes a support block 41, a cross slide groove 42 is provided on the support block 41, a cross slide block 43 is arranged inside the cross slide groove 42, and pins 44 for plugging into the ground are fixed at both ends of the bottom of the support block 41. The cross slide block 43 matches the cross slide groove 42, and the cross slide block 43 slides inside the cross slide groove 42.

[0031] In this embodiment, the sliding assembly 4 is limited by plugging the latch 44 into the ground, thereby limiting the position of the tripod, and the three cross slide blocks 43 slide inward or outward simultaneously in their corresponding cross slide grooves 42 .

[0032] In an optional embodiment, the tripod retraction assembly 3 includes a movable seat 31 fixed on the support rod 2, and three legs 32 are movably arranged in a circular array on the movable seat 31. The three legs 32 are respectively connected to the cross sliders 43 corresponding to their bottoms, and the legs 32 rotate on the movable seat 31. A clamp 37 is clamped on the outer periphery of the legs 32, and an outer bearing seat 38 is fixed on the clamp 37. A screw rod 33 is movably arranged at the bottom of the movable seat 31 through a bearing, and a knob 34 is fixed at the bottom of the screw rod 33. The knob 34 drives the screw rod 33 to rotate clockwise and counterclockwise, and a threaded sleeve 35 is screwed on the screw rod 33. Three inner bearing seats 36 are arranged in a circular array around the outer periphery of the threaded sleeve 35. The inner bearing seat 36 and the outer bearing seat 38 are movably connected by a connecting rod 39.

[0033] In this embodiment: the screw rod 33 is rotated by the knob 34. Since the threaded sleeve 35 is limited, the threaded sleeve 35 is driven to perform axial movement in the up and down directions on the screw rod 33, and then the three legs 32 are driven by the connecting rod 39 to move inward or outward at the same time.

[0034] Working principle of this utility model:

[0035] The screw rod 33 is rotated by the knob 34. Since the threaded sleeve 35 is limited, the threaded sleeve 35 is driven to make axial movement in the up and down directions on the screw rod 33. Then, the three legs 32 are driven to move inward or apart outward at the same time through the connecting rod 39. Then, the three cross slide blocks 43 are driven to slide inward or outward at the same time in their corresponding cross slide grooves 42. The height adjustment of the level can be completed without pulling out the pin plugged into the ground. The device has strong flexibility and is more convenient and practical.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
