2. The angle can be adjusted to the building support frame. By rotating the rotating gear, the pawl meshing with the rotating gear will move inwardly, so that the ratchet disc and the lifting gear can rotate in the opposite direction, driving the adjustment plate to descend, and the support rod is moved by the vertical The straight state changes to the inclined state, and the device returns to the initial state, which is convenient for recycling.

3. The angle can be used to adjust the support frame for the building. Because the construction site is complex, many places that need support have an inclination angle. Through the forward and reverse rotation of the threaded rod, the two push plates can respectively push different movable blocks on the left and right sides. , to complete the adjustment of the inclination angle, which greatly increases the applicability of the support frame.

4. The angle can be adjusted to the building support frame. The threaded shaft drives the fixed frame to complete the extension and retraction of the rollers, which facilitates the movement of the device and enhances its flexibility. After the rollers are retracted, turn the bracket to insert the bracket downward. The ground is used to stabilize the device and prevent the rollers from being deformed by hand pressure for a long time during the support process, which will affect the use and prolong their service life.

The support rod 7 is hinged, the other end of the support rod 7 is hinged with the adjustment plate 8, the inside of the adjustment plate 8 is movably connected with a threaded rod 16, the threaded rod 16 is movably connected with a push plate 17, and the outside of the push plate 17 is movably connected with a movable block 18. The push plate 17 and the movable block 18 can slide on the threaded rod 16. The movable block 18 is hinged with the lower surface of the support plate 19 through the connecting rod. The upper surface of the support plate 19 is provided with anti-skid protrusions to prevent side slip during support operations , the spring shaft 6 and the support rod 7 have eight groups in total, and are arranged on both sides of the lifting gear 9. The top of the fixed plate 5 is movably connected with the lifting gear 9, and the front of the lifting gear 9 is hinged with a swing rod 10. The swing rod 10 The other end is hinged with hinged rod 11, and the other end of hinged rod 11 is hinged with lifting shaft 12, and lifting gear 9, swing rod 10, hinged rod 11, lifting shaft 12 all have two groups, and lifting gear 9 has fixed rod to fix, and two Group lifting gear 9 rotation directions are opposite, and the interior of lifting gear 9 is movably connected with ratchet disc 13, and the interior of ratchet disc 13 is movably connected with ratchet 14, and ratchet 14 has two groups, and the end of ratchet 14 is movably connected with telescopic spring, One side of the ratchet 14 is provided with a rack, and the rack is meshed with the rotating gear 15 .

Working process and principle: use the rotating motor to drive the threaded shaft 2 to rotate, the threaded block drives the fixed frame 3 to move downward, the rollers extend out of the base 1, and after the device is moved to the position that needs to be supported, the motor rotates in the opposite direction to drive the fixed frame 3 Rise up, retract the rollers into the base 1, turn the bracket 4, and insert the bracket 4 downward into the ground. If the bottom surface is uneven, you can also adjust the four brackets 4 to descend to different heights to stabilize the device and prevent the rollers from being supported. Long-term hand pressure deforms, which affects the use. When the four pressure sensors between the base 1 and the fixed plate 5 display the same data, that is, the device is in a horizontal state, and the two lifting gears 9 are controlled by the motor to rotate in opposite directions. At this time The swing lever 10 will rotate with the hinge point on the lifting gear 9 as the center of a circle, driving the hinge lever 11 to move upwards, and the lifting shaft 12 will move upwards at the same time, and the adjusting plate 8 will rise. When the adjusting plate 8 rises, the slide on the spring shaft 6 The block will slide to the inside, and the support rods 7 will gradually become vertical by inclination. The eight support rods 7 symmetrically arranged on both sides can avoid the tilting of the adjustment plate 8 when they are in the vertical state. The anti-skid protrusions can effectively avoid the sideslip phenomenon of the adjustment plate 8 during the support process. The lifting gear 9 is provided with a ratchet disc 13 and a pawl 14. When the pawl 14 is not opened, the rotation direction of the lifting gear 9 is fixed. , the reverse rotation is locked to prevent accidents when the adjustment plate 8 and the support fall beyond the weight of the adjustment plate 8 and the accident occurs, thereby ensuring the safety of use.

Because the building site situation is complicated, when there is an inclination angle in the place that needs to be supported, the threaded rod 16 can be rotated. When turning forward, the push plate 17 moves to the left. The height on the left is lowered, the movable block 18 on the right does not move, and the support plate 19 forms an inclination angle with the left low and the right high. When the threaded rod 16 reverses, the inclination angle is opposite. Through the forward rotation and reverse rotation of the threaded rod 16, Let the two push plates 17 push the different movable blocks 18 on the left and right sides to complete the adjustment of the inclination angle, which greatly increases the applicability of the support frame.

When the support frame needs to be moved out, the rotating gear 15 is rotated, and the ratchet 14 meshed with the rotating gear 15 will move inwardly. At this time, the ratchet disc 13 can rotate in the opposite direction, that is, the lifting gear 9 rotates in the opposite direction, driving the adjustment plate 8 descends, and the support bar 7 changes from the vertical state to the inclined state, and the device returns to the initial state.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
