DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figures 1-10 , a prefabricated residential frame safety connection structure, including a support column 1 and a frame body 2, a support seat 3 is fixedly installed on the support column 1 by screw and nut fixings, a support groove 4 is opened at the upper end of the support seat 3, one side of the frame body 2 is inserted in the support groove 4, a mounting groove 5 is opened in the support groove 4, a lifting block 6 is vertically slidably installed in the mounting groove 5 through an adjusting component, a first telescopic spring 7 is fixedly installed on the upper surface of the lifting block 6, and a top block 8 is fixedly installed on the end of the first telescopic spring 7 away from the lifting block 6, a threaded hole connected to the mounting groove 5 is opened at the lower end of the support seat 3, the adjusting component includes a threaded rod 11 threadedly inserted in the threaded hole and a hexagonal block 12 fixedly installed at the lower end of the threaded rod 11, the threaded rod 11 extends into one end of the mounting groove 5 and is rotatably connected to the lifting block 6, and the side wall of the lifting block 6 is in sliding contact with the inner wall of the mounting groove 5.

[0033] The support seat 3 is fixedly mounted on the support column 1 by screw and nut fixings. One end of the threaded rod 11 is rotatably connected to the lifting block 6. The hexagonal block 12 can be rotated by a tool wrench, thereby driving the threaded rod 11 to rotate in the threaded hole, and then the lifting block 6 is driven up and down in the installation groove 5 by the threaded rod 11. When the lifting block 6 moves, the top block 8 can be driven to move in the support groove 4 by the first telescopic spring 7.

[0034] A rectangular groove is provided on the side wall of the support groove 4, and a stopper 10 is slidably installed in the rectangular groove through a second telescopic spring 9. A transmission assembly for driving the stopper 10 to move into the rectangular groove is provided on the support seat 3. A square groove is provided on the side wall of the mounting groove 5, and a connecting hole is provided between the square groove and the rectangular groove. The transmission assembly includes a movable plate 13 vertically slidably installed in the square groove through an elastic component and a pull rope 14 inserted in the connecting hole. One end of the movable plate 13 extends into the mounting groove 5 and contacts the lower surface of the lifting block 6. Both ends of the pull rope 14 extend into the rectangular groove and the square groove respectively, and both ends are fixedly connected to the stopper 10 and the movable plate 13 respectively.

[0035] The stopper 10 is slidably installed in the rectangular groove by the second telescopic spring 9. When one end of the stopper 10 moves out of the rectangular groove, it can block the notch of the support groove 4, thereby preventing the frame body 2 inserted in the support groove 4 from moving out. When installing the frame body 2, the hexagonal block 12 is rotated to drive the threaded rod 11 to rotate, driving the lifting block 6 to move vertically downward in the installation groove 5. The lifting block 6 then drives the top block 8 to move vertically downward through the first telescopic spring 7. When the lifting block 6 moves vertically downward, it contacts the moving plate 13 and drives the moving plate 13 to move downward together. When the moving plate 13 moves downward, it pulls the stopper 10 into the rectangular groove through the pull rope 14. The second telescopic spring 9 is compressed to fully insert the stopper 10 into the rectangular groove. At this time, the notch of the support groove 4 is open, making it convenient to place one side of the frame body 2 in the support groove 4 and on the top block 8, and then rotate the threaded rod 11 in the opposite direction. When the first telescopic spring 7 is compressed to the maximum extent, the frame body 2 will be tightly contacted with the stopper 10 under the action of the elastic force, so that the frame body 2 is clamped between the stopper 10 and the top block 8, completing the installation of the frame body 2. The installation process is simple, time-saving and labor-saving, effectively improving the installation efficiency and speeding up the project progress.

[0036] The elastic component includes a vertical rod 15 vertically fixedly installed in the square groove and a third telescopic spring 16 sleeved on the vertical rod 15. The two ends of the third telescopic spring 16 are respectively fixedly connected to the inner wall of the square groove and the upper surface of the movable plate 13. The movable plate 13 is vertically slidably installed in the square groove through the vertical rod 15 and the third telescopic spring 16. When the lifting block 6 moves vertically downward, it drives the movable plate 13 to move vertically downward, and the third telescopic spring 16 is stretched. When the lifting block 6 moves vertically upward, under the action of the elastic force of the third telescopic spring 16, the movable plate 13 moves vertically upward.

[0037] The inner wall of the support groove 4 is symmetrically provided with limiting grooves, and the limiting blocks 17 are symmetrically fixedly installed on the lower surface of the top block 8. The two limiting blocks 17 are respectively slidably inserted into the two limiting grooves. The limiting blocks 17 can move up and down in the limiting grooves. Under the limitation of the limiting blocks 17 and the limiting grooves, the top block 8 can be ensured to move vertically up and down in the support groove 4.

[0038] A positioning block 18 is fixedly installed on the upper surface of the top block 8. The longitudinal section of the positioning block 18 is trapezoidal. When the frame body 2 is placed on the top block 8, the frame body 2 contacts the inclined surface of the positioning block 18. When the frame body 2 is clamped between the top block 8 and the stop block 10, the inclined surface of the positioning block 18 will apply a force perpendicular to the inclined surface to the frame body 2. Under the action of the force, the frame body 2 contacts the side wall of the support groove 4, thereby preventing the frame body 2 from moving horizontally between the top block 8 and the stop block 10, further improving the stability of the installation of the frame body 2.

[0039] A circular plate 19 is fixedly mounted on the hexagonal block 12, and arc grooves 20 are symmetrically opened on the circular plate 19. A torsion spring 21 is fixedly mounted on the lower end of the support seat 3, and the torsion spring 21 is sleeved on the threaded rod 11. A positioning ring 22 is fixedly mounted on the end of the torsion spring 21 away from the support seat 3. A clamping block 23 is symmetrically fixedly mounted on the side of the positioning ring 22 close to the circular plate 19. The two clamping blocks 23 are respectively inserted in the two arc grooves 20, and a shifting block 24 is symmetrically fixedly mounted on the side of the positioning ring 22.

[0040] When the hexagonal block 12 needs to be rotated, the positioning ring 22 is driven away from the circular plate 19 by the shift block 24, and the clamping block 23 is moved out of the arc groove 20. After the rotation of the hexagonal block 12 is completed, the positioning ring 22 can be rotated by the shift block 24, and the torsion spring 21 undergoes torsional deformation, so that the positioning ring 22 has a rotation tendency of the hexagonal block 12 driving the lifting block 6 to move upward, and then the two clamping blocks 23 on the positioning ring 22 are respectively inserted into the two arc grooves 20. Under the action of the elastic force of the torsion spring 21, the hexagonal block 12 always has a rotation tendency, and its rotation tendency is the rotation tendency of the threaded rod 11 driving the lifting block 6 to move upward, which can prevent the threaded rod 11 from loosening, thereby ensuring the stability of the residential frame installation.

[0041] A slider 25 is vertically slidably installed on the support seat 3 through a sliding assembly, a hinge column 26 is fixedly installed on the slider 25, and a balance bar 27 is rotatably installed on the hinge column 26. Support rods 28 are fixedly installed at both ends of the balance bar 27, and the two support rods 28 are in contact with the frame body 2. An indicator rod 29 is vertically fixedly installed on the lower surface of the balance bar 27. The sliding assembly includes a slide rail 30 fixedly installed on the support seat 3 and a fourth telescopic spring 31 sleeved on the slide rail 30. The slider 25 is slidably sleeved on the slide rail 30, and the two ends of the fourth telescopic spring 31 are fixedly connected to the slide rail 30 and the slider 25 respectively. Under the action of the elastic force of the fourth telescopic spring 31, the slider 25 tends to move vertically upward on the slide rail 30, and the hinge column 26 is rotatably connected to the center of the balance bar 27.

[0042] When the frame body 2 is placed on the support groove 4, the support rods 28 at both ends of the balance rod 27 are in contact with the frame body 2. At the same time, the slider 25 is driven vertically downward by the balance rod 27, so that the two support rods 28 are in tight contact with the frame body 2. When the frame body 2 is horizontally installed in the support groove 4, the balance rod 27 is in a horizontal state. If the frame body 2 is loose when installed and fails to maintain a horizontal state, or if the frame body 2 itself is bent and deformed, the balance rod 27 will tilt, which can be judged by observing the deflection of the indicator rod 29, thereby reminding the staff to perform maintenance, effectively improving the safety of residential frame assembly.

[0043] In the present invention, when installing the frame body 2, the lifting block 6 is driven to move vertically downward in the installation groove 5 by the adjustment component, and the lifting block 6 is then driven to move vertically downward by the first telescopic spring 7. When the lifting block 6 moves vertically downward, the stopper 10 is completely inserted into the rectangular groove through the transmission component. At this time, the notch of the support groove 4 is open, which is convenient for placing one side of the frame body 2 in the support groove 4 and on the top block 8. Then, the lifting block 6 is driven to move vertically upward by the adjustment component. At this time, one end of the stopper 10 is moved out of the rectangular groove under the action of the elastic force of the second telescopic spring 9, and the notch of the support groove 4 is blocked by the stopper 10. At the same time, the lifting block 6 drives the top block 8 to move vertically upward through the first telescopic spring 7, and the top block 8 drives the frame body 2 to move toward the stop block 10 until the frame body 2 contacts the stop block 10, limiting the movement of the frame body 2, and continues to drive the lifting block 6 to continue to move upward through the adjustment component. At this time, the compression degree of the first telescopic spring 7 will gradually increase, and the elastic force will become greater and greater, until the first telescopic spring 7 is compressed to the maximum extent. Under the action of the elastic force, the frame body 2 will tightly contact the stop block 10, so that the frame body 2 is clamped between the stop block 10 and the top block 8, completing the installation of the frame body 2. The installation process is simple, saves time and effort, effectively improves the installation efficiency, and speeds up the project progress.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
