Detailed Description

The present application is described in further detail below in conjunction with figures 1-4.

The embodiment of the application discloses a locking rod for a steel upright post.

Referring to fig. 1, a locking bar for a steel column includes a support 1, and hoops 2 are connected to both ends of the support 1. Two adjacent steel upright posts 3 are locked through the anchor ear 2, and when the locking rod needs to be disassembled, the locking rod can be disassembled only by unlocking the anchor ear 2, so that the locking rod of the steel upright posts 3 is convenient to disassemble.

Referring to fig. 1, the anchor ear 2 includes a mounting block 21 and a tightening block 22, one end of the mounting block 21 is connected to the support member 1, and the other end abuts against the steel column 3, and the tightening block 22 clamps the steel column 3 with the mounting block 21 to fix the steel column 3. The anchor ear 2 is mounted by the cooperation of the mounting block 21 and the abutting block 22.

Referring to fig. 1 and 2, the middle parts of the mounting block 21 and the abutting block 22 are in arc-shaped arrangement, the mounting block 21 and the abutting block 22 can be provided in plurality, the arc-shaped arrangement of the middle parts of each group of the mounting block 21 and the abutting block 22 is different in diameter, and the mounting block 21 and the abutting block can wrap the steel upright posts 3 with different diameters in a surrounding mode. Bolts 23 are respectively penetrated at two sides of the abutting block 22, the bolts 23 fixedly connect the mounting block 21 and the abutting block 22, and the steel upright 3 is clamped by the mounting block 21 and the abutting block 22 through the bolts 23.

Referring to fig. 2, a gasket 4 is fixedly connected to the inner sides of the circular arcs of the mounting block 21 and the abutment block, and the gasket 4 is made of elastic rubber. The gasket 4 not only increases the friction force between the mounting block 21 and the abutting block 22 and the steel upright 3, but also makes the mounting block 21 and the abutting block 22 not easy to generate marks when clamping the steel upright 3.

Referring to fig. 2 and 3, the support 1 includes a rotation rod 11, a threaded rod 12, and a rotation sleeve 13, the rotation rod 11 is provided in two, and the rotation rod 11 is in one-to-one correspondence with the mounting block 21. One end of the rotating rod 11 is spherical, and the other end is provided with external threads. The rotating rod 11 is arranged on the mounting block 21 in a penetrating way and is in threaded connection with the threaded rod 12, so that the threaded rod 12 can rotate a certain angle relative to the mounting block 21 through the rotating rod 11, and the threaded rod 12 and the rotating sleeve 13 are convenient to adjust.

Referring to fig. 3, the threaded rods 12 are provided in two, the rotating sleeve 13 is sleeved on the two threaded rods 12, and the two threaded rods 12 respectively penetrate out from two ends of the rotating sleeve 13. The threaded rod 12 is in threaded connection with the threaded sleeve, the distance that the threaded rod 12 penetrates out of the threaded sleeve is changed by rotating the threaded rod 12, and the length of the whole supporting piece 1 is changed, so that the locking rod is suitable for steel upright posts 3 with different intervals.

Referring to fig. 3, the pitches of the threads on the two threaded rods 12 are different, so that when the locking rod is installed, the two threaded rods 12 are held, and then the rotating sleeve 13 is rotated, so that the gap between the two threaded rods 12 is changed, and the length of the support member 1 is changed. Therefore, the distance of the supporting piece 1 can still be adjusted after the locking rod is installed, so that the steel upright post 3 can be kept in a vertical state better.

Referring to fig. 3 and 4, one end of the threaded rod 12 is threaded, the other end is smooth, a locking block 5 is sleeved on the smooth end of the threaded rod 12, a sliding block 51 is fixedly connected to one side of the threaded rod 12 in a fitting mode, a sliding groove 121 is formed in the threaded rod 12 along the length direction of the sliding block 121, and the sliding block 51 is inserted into the sliding groove 121. The locking block 5 slides on the threaded rod 12 by the cooperation of the slider 51 and the slide groove 121.

Referring to fig. 3, a tooth block 52 is fixedly connected to one side of the locking block 5, which is close to the rotating sleeve 13, and a tooth slot 131 is formed in one side of the rotating sleeve 13, which is close to the locking block 5, and the rotating sleeve 13 is locked by inserting the tooth block 52 into the tooth slot 131, so that the rotating sleeve 13 is not easy to rotate relative to the threaded rod 12.

Referring to fig. 3, the outer surface of the rotating sleeve 13 is provided with anti-slip patterns 132, and the anti-slip patterns 132 are uniformly distributed around the axial direction of the rotating sleeve 13. The anti-skid threads 132 are provided to facilitate rotation of the rotating sleeve 13, so that the length of the support 1 can be adjusted more conveniently.

The implementation principle of the locking rod for the steel upright post is as follows: the threaded rod 12 is first rotated according to the distance between the two steel uprights 3, so that the length of the support 1 is approximately the same as the distance between the two steel uprights 3. The turning rod 11 is then screwed through the mounting block 21 to the threaded rod 12 by selecting the appropriate mounting block 21 and abutment block according to the diameter of the steel upright 3.

Then, the mounting block 21 at one end is abutted against the steel column 3, then the other side of the steel column 3 is wrapped by the abutting block 22, and then the mounting block 21 and the abutting block 22 are fixedly connected by the bolts 23, so that the mounting block 21 and the abutting block 22 clamp the steel column 3.

Next, the other uninstalled mounting block 21 is abutted against the adjacent one of the steel columns 3, and adjusted to a proper position. The threaded rod 12 is held to rotate the rotating sleeve 13, the length of the supporting piece 1 is finely adjusted, the mounting block 21 is just abutted against the other steel upright 3, and the mounting block 21 and the abutting block 22 are fixedly connected through the bolts 23. The locking block 5 is slid again, and the rotating sleeve 13 is locked by the locking block 5. Thereby completing the installation of the locking lever.

When the locking rod needs to be disassembled after pouring is completed, all bolts 23 are disassembled respectively, so that the two abutting plates are disassembled, and the whole locking rod can be disassembled at the moment. The disassembled locking rod can be recycled, and the steel upright post 3 is not easy to leave marks, so that the lock is more attractive.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
