The design and installation of traffic sign poles need to follow relevant national standards to ensure their stability and visibility. The steel pipe connection clamp is a device used to connect steel pipes, which can ensure the safety and reliability of the pipeline system.
[0003] The traditional steel pipe connection clamp consists of parts such as a crimping ring, a crimping connector, and a crimping tool. By using the crimping tool, the crimping head of the tool is placed at the connection of the steel pipe and the pipe fitting, and appropriate pressure is applied for crimping. During the crimping process, it is necessary to ensure that the crimping head evenly contacts the steel pipe and the pipe fitting to ensure the firmness of the connection.
[0004] The traditional steel pipe connection clamp connects the steel pipes by crimping or welding. However, since crimping connection is usually permanent, once installed, it is difficult to disassemble and reconnect, and it is easy to damage the original anti-corrosion treatment layer of the steel pipe. Therefore, a steel pipe connection clamp is proposed to solve the above problems. Content of the Utility Model
[0005] In order to make up for the above deficiencies, the utility model provides a steel pipe connection clamp, aiming to improve the problems in the prior art that the steel pipes are connected by crimping or welding.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A steel pipe connection clamp includes a lower block. An upper block is arranged on the upper surface of the lower block.

[0022] The utility model has the following beneficial effects:
[0023] In the utility model, by pressing the pressing column, the fixing column slides into the second clamping groove, so that the spring is compressed and contracted, the rotating bar is contracted, and then the conical head penetrates through the mounting plate. Then, the pressing column is released, the spring resets, the side wall of the rotating bar fits with the lower surface of the mounting plate, and then the rotating block is rotated to make it fit with the upper surface of the mounting plate, achieving the effect of rapid installation. This solves the problem that some steel pipe connection clamps connect steel pipes by clamping or welding methods. However, since the clamping connection is usually permanent, once installed, it is difficult to disassemble and reconnect, and it is easy to damage the original anti-corrosion treatment layer of the steel pipe. The convenience of lengthening the steel pipe column is improved through the above structure. Description of the Drawings

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figures 1-3, an embodiment provided by the present utility model: a steel pipe connection clamp, which includes a lower clamping block 1. An upper clamping block 2 is arranged on the upper surface of the lower clamping block 1. Installation plates 3 are fixedly connected to the side walls of both the lower clamping block 1 and the upper clamping block 2. A plurality of installation holes 4 are formed inside the installation plates 3. An auxiliary component is arranged inside the lower clamping block 1 and the upper clamping block 2 for protecting the steel pipe. The auxiliary component includes rubber rings 16. The side walls of the rubber rings 16 are fixedly connected inside the lower clamping block 1 and the upper clamping block 2. A cylindrical outer shell 5 is slidably connected inside the installation plate 3. The side wall of the cylindrical outer shell 5 is slidably connected inside the installation hole 4. A rotating block 6 is rotationally threaded on the side wall of the cylindrical outer shell 5. A pull ring 7 is fixedly connected to the side wall of the cylindrical outer shell 5. A pressing column 8 is slidably connected inside the cylindrical outer shell 5. A fixing block 9 is fixedly connected to the side wall of the pressing column 8. The side wall of the fixing block 9 is slidably connected inside the cylindrical outer shell 5. A rotating bar 10 is rotationally connected to the side wall of the fixing block 9. One end of the cylindrical outer shell 5 is fixedly connected to a conical head 11. A first clamping groove 12 is formed inside the conical head 11. A second clamping groove 13 is formed inside the conical head 11. A fixing column 14 is fixedly connected to the lower surface of the pressing column 8. A spring 15 is sleeved on the side wall of the fixing column 14. One end of the spring 15 is fixedly connected inside the conical head 11, and the other end of the spring 15 is fixedly connected to the side wall of the fixing column 14. The side wall of the fixing block 9 is slidably connected inside the first clamping groove 12. The side wall of the pressing column 8 is slidably connected inside the second clamping groove 13. The side wall of the fixing column 14 is slidably connected inside the second clamping groove 13.
[0031] In actual engineering applications, when the rod needs to be lengthened, firstly, the steel pipe to be lengthened is docked with the original steel pipe to ensure that the connection between the two is tight and seamless, and then the upper clamping block 2 and the lower clamping block 1 are respectively clamped at the connection between the lengthened steel pipe and the original steel pipe to ensure the stability of the connection. Next, by pressing the pressing column 8, it moves downward inside the cylindrical shell 5. As the pressing column 8 moves downward, the fixed block 9 will also slide down and then slide into the inside of the card slot 1 12. In this process, the rotating bar 10 will be squeezed, thereby shrinking and fitting the side wall of the cylindrical shell 5. At the same time, the fixed column 14 will also slide down inside the card slot 2 13, causing the spring 15 to be squeezed and shrink. After completing the above steps, it is necessary to pass the conical head 11 through the mounting plate 3 to further fix the steel pipe. Subsequently, the pressing column 8 is released, so that the spring 15 loses the extrusion force and rebounds. The rebound force of the spring 15 will push the fixing column 14 upward, thereby driving the pressing column 8 and the rotating bar 10 to move upward together. The rotating bar 10 will unfold during the upward movement and be stuck on the lower surface of the mounting plate 3, thereby achieving the fixation of the two steel pipes. Finally, it is necessary to rotate the rotating block 6 so that it fits to the upper surface of the mounting plate 3 to ensure the stability of the entire connection structure. The lower clamping block 1 and the upper clamping block 2 are in a corresponding relationship, and the size, dimensions, and mounting holes 4 are all in the same symmetrical relationship. The lower clamping block 1 and the upper clamping block 2 can be provided with four or six bolt holes on each side according to the diameter of the steel pipe; different clamps can be made according to the on-site round pipe or square pipe. When it is necessary to lengthen the on-site steel pipe column, there is no need to remove the old rod. It is only necessary to use the steel pipe to connect the lengthened part of the clamp to dock with the original column, and then fix it with the columnar shell 5, which is convenient and fast.
[0032] Working principle: when it is necessary to lengthen the rod of the column steel pipe, the steel pipe to be added is connected to the original steel pipe, and then the upper clamping block 2 and the lower clamping block 1 are clamped at the connection between the lengthened steel pipe and the original steel pipe, and then the pressing column 8 is pressed to move it downward inside the cylindrical shell 5, and the fixed block 9 is pushed down to slide into the inside of the card slot 12, so that the rotating bar 10 is squeezed and contracted to fit the side wall of the cylindrical shell 5, and at the same time, the fixed column 14 is allowed to slide down inside the card slot 2 13, so that the spring 15 is squeezed and contracted, and then the conical head 11 is passed through the mounting plate 3, and then the pressing column 8 is released to make the spring 15 lose the extrusion rebound, thereby pushing the fixed column 14 to move upward, so that the pressing column 8 moves upward and drives the rotating bar 10 to move upward, thereby unfolding the rotating bar 10 and making it stuck on the lower surface of the mounting plate 3, and then the rotating block 6 is rotated to make it fit to the upper surface of the mounting plate 3 to complete the fixation, thereby clamping the two steel pipes.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
