Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a bracket that is convenient to adjust. Background Art

[0002] When building construction is carried out, in order to facilitate workers to reach the top of the building, workers usually need to step on the bracket to construct the top of the building. However, during the use of the existing construction bracket, in order to facilitate its own movement, universal wheels are usually provided at the four corners of the bracket. When the bracket is in use, the universal wheels need to be braked and positioned to ensure stability. However, since there are usually four universal wheels and there is a large distance between the four universal wheels, when braking the four universal wheels, the staff needs to surround the bracket and brake the four universal wheels separately in turn, which is rather troublesome when braking. Summary of the Invention

[0003] An embodiment of the present disclosure relates to a bracket that is convenient to adjust. By providing a transmission rod, the transmission rod drives the top push rod to descend, so that the top push rod contacts the wheel wall of the moving wheel through the descent, thereby using the contact between the top push rod and the wheel wall of the moving wheel to achieve the braking of the moving wheel. Thus, after the bracket is put into use, the moving wheel will not increase the instability of the bracket, and the safety of workers when using the bracket is improved.

[0030] Move this bracket to the construction area to be constructed through the moving wheel 8, and then rotate the control lead screw 10 by the staff, so that the control lead screw 10 drives one ends of the two sliding sleeves 11 and the two groups of expansion linkages 12 to move relatively outward under the action of the threads, and thus start the braking work on the moving wheel 8.

[0031] Embodiment 2, on the basis of Embodiment 1,

[0032] Two opposite threads are formed on the circumferential outer wall of the control lead screw 10; sliding sleeves 11 are installed on the control lead screw 10 through the threads; an operation handwheel is fixedly installed at the front end of the control lead screw 10; one end of an expansion linkage 12 is rotatably installed on the circumferential outer wall of the sliding sleeve 11; a cylindrical top push column 15 is fixedly installed on the sliding seat 14; a top push plate 16 is fixedly installed at the outer end of the sliding seat 14; the position of the top push plate 16 corresponds to the position of the stress groove 5.

[0033] When one end of the expansion linkage 12 moves outward, the other end of the expansion linkage 12 pushes the sliding seat 14 outward along the guide groove 13, so that the sliding seat 14 drives the top push column 15 and the top push plate 16 to move outward, so that the outer end of the top push plate 16 is inserted into the stress groove 5 through outward movement, and the outer end of the top push plate 16 pushes against the inclined surface of the stress groove 5, so that the transmission rod 4 drives the top push rod 6 to move downward under the influence of the force on the stress groove 5, so that the top push rod 6 contacts the wheel wall of the moving wheel 8 through downward movement, so that the top push rod 6 brakes the moving wheel 8 and positions the bracket.

[0034] Embodiment 3, on the basis of Embodiment 2,

[0035] A transmission groove 18 is formed on the outer side of the transmission plate 17; the push rod 15 is also slidably connected to the transmission groove 18; a contact floor plate 19 is fixedly installed at the bottom end of the transmission plate 17; the other end of the expansion link 12 is also rotatably connected to the sliding seat 14; the transmission groove 18 is composed of an inclined groove and a transverse groove, and the highest end of the inclined groove is communicated with the inner end of the transverse groove; friction lines are formed on the bottom of the contact floor plate 19; a spring B 20 is jointly embedded between the top of the contact floor plate 19 and the bottom of the reinforcement plate 9.

[0036] When the push rod 15 moves outwards, the push rod 15 will use the inclined groove part of the transmission groove 18 to convert the outward movement force into a downward force and provide it to the transmission plate 17, so that the transmission plate 17 drives the contact floor plate 19 to move downwards under the force, so that the contact floor plate 19 contacts the ground by moving downwards, enhancing the grounding stability of the support after it is put into use. Then the staff can climb onto the support plate 3 through the support cross frame 2 to carry out construction.

[0037] The working principle of this embodiment:

[0038] In use, the support is moved to the construction area to be constructed through the moving wheels 8. Then, the staff rotates the control screw rod 10, so that the control screw rod 10 drives one ends of the two sliding sleeves 11 and the two groups of expansion links 12 to move relatively outwards under the action of the screw threads by rotation, so that the other ends of the two groups of expansion links 12 push the sliding seat 14 outwards along the guide groove 13, so that the sliding seat 14 drives the push rod 15 and the push plate 16 to move outwards, so that the push plate 16 is inserted into the inner part of the force receiving groove 5 by moving outwards, and the outer end of the push plate 16 pushes the inclined surface of the force receiving groove 5, so that the transmission rod 4 drives the push rod 6 to move downwards under the influence of the force received by the force receiving groove 5, so that the push rod 6 contacts the wheel wall of the moving wheel 8 by moving downwards, so that the push rod 6 brakes the moving wheel 8 to position the support. And when the push rod 15 moves outwards, the push rod 15 will use the inclined groove part of the transmission groove 18 to convert the outward movement force into a downward force and provide it to the transmission plate 17, so that the transmission plate 17 drives the contact floor plate 19 to move downwards under the force, so that the contact floor plate 19 contacts the ground by moving downwards, enhancing the grounding stability of the support after it is put into use. Then the staff can climb onto the support plate 3 through the support cross frame 2 to carry out construction.
