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.
[0023] The utility model provides a laser leveling device which is easy to level. Figure 1-5As shown, it includes a truncated table 1 and a laser instrument 2. The upper surface of the laser instrument 2 is fixedly connected with a handle 20. The shape of the handle 20 is arc-shaped, which can facilitate the carrying of the instrument. The lower surface of the laser instrument 2 is rotatably plugged into the upper surface of the truncated table 1. The front side of the truncated table 1 is hinged with a front leg 3. The lower surface of the truncated table 1 is rotatably plugged with a threaded rod 4. The outer surface of the threaded rod 4 is meshed with a threaded collar 5. When the instrument needs to be used, the instrument is lifted so that the three front legs 3 are slightly higher than the ground. After the laser instrument is in a horizontal state, the swivel 19 is rotated. The lower end of the threaded rod 4 is fixedly connected with a swivel 19. The shape of the swivel 19 is hexagonal, which can make the rotation of the swivel 19 more convenient. The front side of the threaded collar 5 is hinged with a cross bar 6. The rear end of the cross bar 6 is hinged with the rear side of the front leg 3. The swivel 1 9 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the threaded collar 5 to move upward, and the threaded collar 5 pulls the front leg 3 to rotate backward through the cross bar 6. The lower surface of the round table 1 is fixedly connected with an electric telescopic rod 7, and the electric telescopic rod 7 can be started forward or reversely. The electric telescopic rod 7 is arranged on the rear side of the threaded rod 4. The lower surface of the round table 1 is fixedly connected with two fixed legs 8. The two fixed legs 8 are symmetrically arranged with the threaded rod 4 as the center. A groove 9 is provided on one side of the two fixed legs 8 close to the threaded rod 4. A movable leg 10 is slidably inserted in the two grooves 9. The lower ends of the two movable legs 10 are fixedly connected with a pad 18. The pad 18 is made of rubber material. After the pad 18 contacts the ground, the stability of the instrument as a whole can be ensured. The legs 10 are fixedly connected to the side close to the threaded rod 4 with a spring telescopic rod 11, and the upper ends of the two spring telescopic rods 11 are fixedly connected to the free ends of the electric telescopic rod 7. When the current leg 3 contacts the ground, the electric telescopic rod 7 is turned on, and the electric telescopic rod 7 drives the two spring telescopic rods 11 to move downward, and the spring telescopic rod 11 drives the mobile legs 10 to move downward. A plurality of square grooves 12 are provided on the side of the two mobile legs 10 away from the threaded rod 4, and the lower ends of the two mobile legs 10 are fixedly connected to a connecting plate 13, and the lower bottom wall of the connecting plate 13 is fixedly connected to a spring member 14, and the ends of the two spring members 14 close to the mobile legs are fixedly connected to a stopper 15, and when the square groove 12 contacts the stopper 15, the spring member 14 pushes the stopper 15 into the square groove 12, and the stopper The upper surface of the block 15 is inclined, and the height of the block 15 is equal to the height of the square groove 12. When the movable leg 10 continues to move downward, the movable leg 10 pushes the block 15 to move outward. When the pad 18 on the left side contacts the ground, the spring member 14 moves inward to reset and drives the block 15 to enter the square groove 12. The block 15 blocks the movable leg 10 from moving upward. The ground will block the movable leg 10 on the left side from moving downward. The electric telescopic rod 7 continues to drive the spring telescopic rod 11 on the left side to compress downward. The electric telescopic rod 7 will also continue to drive the spring telescopic rod 11 on the right side and the movable leg 10 on the right side to move downward. When the pad 18 on the right side contacts the ground, the block 15 will also enter the square groove 12 to block the movable leg 10 from moving upward.The three legs are in contact with the ground and the laser instrument 2 is also in a horizontal state, so the measurement can be carried out. The two blocks 15 are fixedly connected to the side away from the movable leg 10 with a buckle 16. The two buckle 16 slide through the side of the connecting plate 13 away from the movable leg 10. The two connecting plates 13 are fixedly connected to the side away from the movable leg 10 with a baffle 17. The baffle 17 is arranged on the lower side of the buckle 16. When the measurement is completed, the buckle 16 is pulled outward, and the buckle 16 drives the block 15 to move outward. The block 15 leaves the square groove 12, and the buckle 16 is buckled into the lower side of the baffle 17. The baffle 17 will prevent the buckle 16 from moving inward, and the electric telescopic rod 7 is started in the reverse direction.

[0024] Working principle: when the instrument needs to be used, lift the instrument so that the three front legs 3 are slightly higher than the ground. After the laser instrument is in a horizontal state, turn the swivel 19, the swivel 19 drives the threaded rod 4 to rotate, the threaded rod 4 drives the threaded collar 5 to move upward, and the threaded collar 5 pulls the front leg 3 to rotate backward through the cross bar 6. After the front leg 3 contacts the ground, the electric telescopic rod 7 is turned on, and the electric telescopic rod 7 drives the two spring telescopic rods 11 to move downward, and the spring telescopic rod 11 drives the movable leg 10 to move downward. When the square groove 12 contacts the stopper 15, the spring member 14 pushes the stopper 15 into the square groove 12, and the upper surface of the stopper 15 is inclined. When the movable leg 10 continues to move downward, the movable leg 10 pushes the stopper 15 to move outward. When the pad 18 on the left side contacts the ground, the spring member 14 moves inward to reset and drives the stopper 15 to enter the square groove 12. The stopper 15 blocks the movable leg 10 from moving upward. The electric telescopic rod 7 will stop the movable leg 10 on the left from moving downward, and the electric telescopic rod 7 will continue to drive the spring telescopic rod 11 on the left to be compressed downward. The electric telescopic rod 7 will also continue to drive the spring telescopic rod 11 on the right and the movable leg 10 on the right to move downward. When the pad 18 on the right side touches the ground, the block 15 will also enter the square groove 12 to stop the movable leg 10 from moving upward. The electric telescopic rod 7 will be closed. When the measurement is completed, the buckle 16 is pulled outward, and the buckle 16 drives the block 15 to move outward. The block 15 leaves the square groove 12 and buckles the buckle 16 into the lower side of the baffle 17. The baffle 17 will stop the buckle 16 from moving inward, and the electric telescopic rod 7 will be started in reverse. The electric telescopic rod 7 will drive the spring telescopic rod 11 to move upward and reset, and the spring telescopic rod 11 will drive the movable leg 10 to move upward and reset, and the electric telescopic rod 7 will be closed again, and the swivel 19 will be turned to reset the front leg 3.
