DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] As Figure 1 shown, in embodiment one, a telescopic horizontal steel bar support fixture, comprising: moving frame 1, connecting frame 2, connecting rod 3 and chain 4;

[0022] The moving frame 1 is provided with multiple groups, and the bottom end of the moving frame 1 is provided with universal wheels 8 on both sides. Multiple groups of connecting frames 2 are arranged between every two moving frames 1. The moving frame 1 and the connecting frame 2 are fixedly installed with rotating shafts 5 inside. The bottom end of the moving frame 1 and the connecting frame 2 is provided with sliding grooves 7 on the inner wall of both sides. The moving shaft 6 is slidably installed inside the sliding groove 7. The connecting rod 3 is provided with multiple groups. The two ends of the connecting rod 3 are rotatably installed on the rotating shaft 5 and the moving shaft 6 adjacent to it. The connecting rod 3 forms a scissor shape. The chain 4 comprises upper chain 4.1 and lower chain 4.2. The two ends of the upper chain 4.1 are detachably installed on the rotating shaft 5 adjacent to it. The two ends of the lower chain 4.2 are detachably installed on the rotating shaft 5 on the moving frame 1.

[0023] When the horizontal steel bar needs to be positioned and installed, two groups of embodiment one are prepared. According to the required steel bar spacing length, the length of the upper chain 4.1 is selected. The two ends of the upper chain 4.1 are installed on the rotating shaft 5 adjacent to it. After installation is completed, the moving frame 1 is pulled in the opposite direction, so that the spacing between the connecting frames 2 changes. When the upper chain 4.1 is in a straight state, the moving frame 1 cannot move, which represents that the distance between the connecting frames 2 is equidistantly distributed at this time.

[0024] When the moving frame 1 moves, the connecting rod 3 rotates, the angle between the two connecting rods 3 changes, and the moving shaft 6 is displaced upward in the sliding groove 7. When the chain 4 is taut, the universal wheel 8 is locked, so that the two moving frames 1 are locked, preventing the moving frames 1 from moving close to each other, causing the distance between the connecting frames 2 to change, and causing the steel bar positioning to be not accurate enough.

[0025] When the mobile frame 1 is locked, the two ends of the steel bar are clamped at the included angle of the connecting rod 3 in the two groups of example one, and the horizontal steel bar is stably installed.

[0026] After installation is completed, pull the lower chain 4.2 to pull the mobile frame 1 at one end, and store the two mobile frames 1.

[0027] As shown in Figures 2-3 In example two, the mobile shaft 6 on the connecting frame 2 is provided with a locking assembly 9, which can lock the mobile rod in the height direction.

[0028] When positioning and installing the horizontal steel bar is needed, two groups of example two are prepared, the upper chain 4.1 of the required length is selected according to the required steel bar spacing length, the two ends of the upper chain 4.1 are installed on the adjacent rotating shaft 5, after installation is completed, the mobile frame 1 is pulled in the opposite direction, so that the spacing between the connecting frames 2 changes, when the upper chain 4.1 is in a straight state, the mobile frame 1 cannot move, which represents that the distance between the connecting frames 2 is equidistantly distributed;

[0029] When the mobile frame 1 moves, the connecting rod 3 rotates, the angle between the two connecting rods 3 changes, and the mobile shaft 6 moves upward in the sliding groove 7, when the chain 4 is taut, the universal wheel 8 is locked, the mobile frame 1 is locked more stably by the utility locking assembly 9, which prevents the mobile frame 1 from moving close to each other, causing the distance between the connecting frames 2 to change, resulting in inaccurate positioning of the steel bar;

[0030] When the mobile frame 1 is locked, the two ends of the steel bar are clamped at the included angle of the connecting rod 3 in the two groups of example one, and the horizontal steel bar is stably installed.

[0031] The locking assembly 9 comprises a plug rod 9.1, a moving block 9.2 and a plug block 9.3, the plug rod 9.1 is fixedly installed on one side of the outer wall of the mobile shaft 6, the side of the mobile shaft 6 close to the plug rod 9.1 is provided with a cavity 6.1, the inner wall of the cavity 6.1 is fixedly installed with a limiting rod 6.2, the surface of the moving block 9.2 is provided with a threaded groove 9.4, and the limiting rod 6.2 is slidingly installed in the threaded groove 9.4.

[0032] When the locking assembly 9 is used, the lower chain 4.2 is straightened, the chain link is sleeved on the plug rod 9.1, the lower chain 4.2 is pulled to the left, the mobile shaft 6 is rotated, the limiting rod 6.2 is rotated after the mobile shaft 6 is rotated, the limiting rod 6.2 slides in the threaded groove 9.4, and the moving block 9.2 moves toward the sliding groove 7.

[0033] The insertion block 9.3 is fixedly installed on the side of the moving block 9.2 away from the moving shaft 6, and the sliding groove 7 is internally provided with a strip-shaped slot 7.1, and the insertion block 9.3 is slidingly installed in the strip-shaped slot 7.1.

[0034] When the moving shaft 6 rotates, the insertion block 9.3 is blocked by the strip-shaped slot 7.1, so that the insertion block 9.3 cannot rotate, and the limiting rod 6.2 can drive the threaded slot 9.4 to rotate, and drive the moving block 9.2 to rotate, and drive the insertion block 9.3 to move towards the sliding groove 7.

[0035] The strip-shaped slot 7.1 is internally provided with a plurality of insertion holes 7.2 at equal intervals, and the insertion block 9.3 can be inserted into the insertion hole 7.2.

[0036] When the insertion block 9.3 moves towards the sliding groove 7, it can be inserted into the insertion hole 7.2, so that the moving shaft 6 is locked in the height direction, so that the connecting rod 3 cannot move relatively, and the moving frame 1 and the connecting frame 2 are locked, so that the distance between the moving frame 1 and the connecting frame 2 cannot change, and the stability is improved when placing the horizontal steel bar;

[0037] After installation, the lower chain 4.2 is pulled in the opposite direction, so that the moving shaft 6 rotates in the opposite direction, and the insertion block 9.3 is taken out of the insertion hole 7.2, and then the lower chain 4.2 is taken out of the insertion rod 9.1, and the lower chain 4.2 is pulled to pull the moving frame 1 at one end, and the two moving frames 1 are stored.

[0038] Compared with example one, example two can lock the height of the moving shaft 6 when locking the movement of the moving frame 1, so that the connecting rod 3 cannot move relatively, and the stability of locking the moving frame 1 and the connecting frame 2 is improved.

[0039] As shown in Figures 4-5 In example three, the moving shaft 6 on the connecting frame 2 is provided with a locking assembly 9 on both sides, and the threaded slots 9.4 in the locking assemblies 9 on both sides are in opposite directions.

[0040] When the moving shaft 6 rotates, the insertion block 9.3 on both sides can be inserted into the insertion hole 7.2, so that the moving shaft 6 can be stably clamped in the sliding groove 7;

[0041] Compared with example two, example three can stably install the moving shaft 6 on both sides in the sliding groove 7, and improve the stability of locking.

[0042] After installation, the lower chain 4.2 is pulled reversely, the moving shaft 6 is reversely rotated, the plug 9.3 is taken out of the socket 7.2, the lower chain 4.2 is taken out of the plug rod 9.1, the lower chain 4.2 is pulled, the moving frame 1 at one end is pulled, and the two moving frames 1 are stored.

[0043] The technical scope of the utility model is not limited to the above-mentioned content in the specification, and the above-mentioned embodiments can be variously deformed and modified by the person skilled in the art without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the scope of the utility model.
