Description

Technical Field

[0001] The utility model relates to the technical field of building plane detection, in particular to a laser spirit level device for quickly detecting the flatness of walls and floors. Background Art

[0002] During the process of building construction, there are generally certain requirements for the flatness and inclination of walls and floors, so it is necessary to detect the standard degree of walls and floors;

[0003] Currently, the flatness and inclination of a certain area of a wall or floor are generally detected by cooperating a spirit level and a feeler gauge (see the attached drawings of the specification Figure 5 ). The measuring surface of the spirit level is pressed against the measured plane, and the size of the gap is detected by a wedge feeler gauge; however, due to the certain width of the feeler gauge, it is impossible to detect small depressions and protrusions on the wall or floor, so a device capable of detecting the flatness of walls and floors with high precision is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above problems and provide a laser spirit level device for quickly detecting the flatness of walls and floors.

[0005] The technical solution of the utility model is: a laser spirit level device for quickly detecting the flatness of walls and floors, including spirit level A, spirit level B, a circular slide bar and a laser rangefinder; both spirit level A and spirit level B are square rod-shaped, and the tops of spirit level A and spirit level B are hinged; the circular slide bar is vertically installed in the middle of the front surface of spirit level A, the axis of the circular slide bar is parallel to the side of spirit level A, and the length of the circular slide bar ≤ the length of spirit level A; the laser rangefinder is slidably installed on the circular slide bar.

[0006] Preferably, the device further includes a sliding seat; the sliding seat is fixedly connected to the end of the laser rangefinder, and the sliding seat is sleeved on the circular slide bar. The laser rangefinder is installed on the sliding seat and can slide up and down along the circular slide bar with the sliding seat.

[0007] Preferably, the laser rangefinder is perpendicular to the front surface of spirit level A and the outer wall thereof is in contact with the left side surface of spirit level A. This can prevent the laser rangefinder from deflecting, resulting in inaccurate measurement results.

[0008] Furthermore, a clamping sliding sleeve is connected to the upper end of the sliding seat, and the clamping sliding sleeve is sleeved on the circular slide bar; the device further includes a fastening nut, and the fastening nut is in threaded cooperation with the clamping sliding sleeve. The fastening nut and the clamping sliding sleeve cooperate to adjust the tightness of the fit between the clamping sliding sleeve and the circular slide bar, so that the sliding seat and the laser rangefinder can be switched among rapid sliding, slow sliding and fixed states.

[0009] Preferably, a spirit level A is horizontally arranged at the upper end of the side surface of the straightedge A, and liftable supporting feet are respectively arranged at the bottom surfaces of the straightedges A and B. The horizontally arranged spirit level can assist the straightedge to maintain a vertical state; the supporting feet can enable the device to stand vertically on an inclined ground.

[0010] Preferably, a spirit level B is longitudinally arranged in the middle of the front surface of the straightedge B, and the axis of the spirit level B is parallel to the side edge of the straightedge B. The longitudinally arranged spirit level can assist the device to maintain a horizontal state when the device is placed flat, making the measurement result more accurate.

[0011] Preferably, the length of the laser rangefinder is less than the thickness of the straightedge A. This can prevent the head of the laser rangefinder from colliding with the wall or the ground.

[0012] Furthermore, the supporting foot includes a supporting seat and a lifting screw rod, and the top of the supporting seat is connected to the bottom of the lifting screw rod by a spherical pair. This can better adapt to the terrain and enable the device to stand more stably.

[0013] The beneficial effects of the present utility model are as follows: A laser straightedge device for quickly detecting the flatness of walls and floors according to the present utility model indirectly represents the inclination degree and flatness of the measured plane by measuring the distance between the measured plane and the laser rangefinder through the sliding of the laser rangefinder on the circular slide bar; and the device has a simple structure, is easy to operate, and has strong practicability.

[0022] Example 1: Refer to Figures 1-5 and Figure 7 , a laser ruler device for quickly detecting the flatness of walls and floors, including ruler A 1, ruler B 2, circular slide bar 5 and laser rangefinder 6; both ruler A and ruler B are square rod-shaped, and the tops of ruler A 1 and ruler B 2 are hinged; ruler A 1 and the top of ruler B 2 are connected by hinge 3, and can be opened into a triangle, making the device more stable and not easy to topple when standing for use. The circular slide bar 5 is vertically installed in the middle of the front of ruler A 1, the axis of the circular slide bar 5 is parallel to the side of ruler A 1, and the length of the circular slide bar 5 ≤ the length of ruler A 1; the laser rangefinder 6 is slidably installed on the circular slide bar 5. The circular slide bar 5 is installed in parallel on the front of ruler A 1, and the laser rangefinder 6 is installed in cooperation with the circular slide bar 5, which can make the laser rangefinder 6 slide along a straight line to ensure the accuracy of the measurement result.

[0023] The device further includes a slide seat 61; the slide seat 61 is fixedly connected to the end of the laser rangefinder 6, and the slide seat 61 is sleeved on the circular slide bar 5. The laser rangefinder 6 is installed on the slide seat 61 and can slide up and down along the circular slide bar 5 with the slide seat 61.

[0024] The laser rangefinder 6 is perpendicular to the front of ruler A 1 and the outer wall is in contact with the left side of ruler A 1. It can prevent the laser rangefinder 6 from deflecting, resulting in inaccurate measurement results.

[0025] The upper end of the slide seat 61 is connected with a clamping slide sleeve 63, and the clamping slide sleeve 63 is sleeved on the circular slide bar 5; the device further includes a fastening nut 62, and the fastening nut 62 is in threaded cooperation with the clamping slide sleeve 63.

[0026] A bubble level A 11 is horizontally arranged at the upper end of the side of ruler A 1, and adjustable support feet 4 are respectively arranged at the bottoms of ruler A and B. The horizontally arranged bubble level can assist the ruler to remain in a vertical state; the support feet 4 can make the device stand vertically on an inclined ground.

[0027] On the middle part of the front side of the level ruler B2, a spirit level B21 is longitudinally arranged, and the axis of the spirit level B21 is parallel to the side of the level ruler B2. The longitudinally arranged spirit level can assist the device to maintain a horizontal state when the device is placed flat, making the measurement result more accurate.

[0028] The length of the laser rangefinder 6 is less than the thickness of the level ruler A1. This prevents the head of the laser rangefinder 6 from colliding with the wall or the ground.

[0029] The usage method of this device:

[0030] (1) Measurement steps for the flatness of the wall:

[0031] ① Separate the bottoms of the level ruler A1 and the level ruler B2 and place them near the wall to be measured.

At this time, the device is vertical;

[0032] ② Adjust the fastening nut 62 to an appropriate tightness level;

[0033] ③ Drag the sliding seat 61 up and down and read the readings of the laser rangefinder 6 along the way;

[0034] ④ Analyze the readings and calculate the flatness of the wall to be measured.

[0035] (2) Measurement steps for the flatness of the ground:

[0036] ① Combine the bottoms of the level ruler A1 and the level ruler B2 and place the level ruler on the ground area to be measured. Point the head of the laser rangefinder 6 at the plane to be measured, and then adjust the heights at both ends of the device to keep the spirit level B21 in the middle position and fix it. At this time, the device is horizontal;
