Description

Steel pipe pole connecting and fastening device Technical Field The utility model relates to the technical field of steel pipe rods, in particular to a steel pipe rod connection fastening device. Background The steel pipe pole is the bracing piece of making with the steel pipe, is common in electric wire tower, street lamp, worker's lower margin hand rack etc. is the member material that fields such as electric power, communication, building are commonly used, because of the length of a steel pipe is limited in the use, so often need carry out fastening connection between steel pipe and the steel pipe to the length needs to the steel pipe pole under the adaptation different scenes, at the in-process of connecting it, often need be with the help of the fastener with two steel pipe poles fixed. However, since the outer diameter of the steel pipe rod is generally smaller than the inner diameter of the fastener, the steel pipe is often prevented from being separated from the fastener even after the bolt is tightened, and the gap between the two cannot be completely eliminated. The loose hidden trouble exists at the connecting part due to the fact that the matching is not tight, and shaking is easy to generate when the connecting part is stressed. (for example, in a scaffold for a construction site, if there is a gap at the joint of steel pipes, the stability of the scaffold body may be reduced, and a constructor may have a falling risk during the operation on the scaffold). Disclosure of utility model The present utility model aims to solve at least to some extent one of the technical problems in the above-described technology. Therefore, an object of the present utility model is to provide a steel pipe pole connection fastening device, in which a spring steel sheet is disposed between fastening pieces, so that when a bolt is used for fastening, the spring steel sheet deforms to press the steel pipe pole, so that the steel pipe pole is fastened with the fastening pieces more tightly, and shaking is not easy to occur. In order to achieve the above purpose, the first aspect of the utility model provides a steel pipe rod connection fastening device, which comprises a connecting pipe, two steel pipe rods and a fastening component, wherein the two steel pipe rods are respectively connected with two ends of the connecting pipe in a sliding way, the fastening component is arranged on the connecting pipe, the fastening component comprises a spring steel sheet and two bolts, wherein a connecting groove is formed in the outer wall of the connecting pipe, the spring steel sheet is arranged in the connecting groove, two fixing holes are formed in the outer wall of the spring steel sheet, threaded holes are respectively formed in the outer walls of the two steel pipe rods, and the two bolts are in threaded connection with the corresponding threaded holes after penetrating through the corresponding fixing holes. In addition, the steel pipe pole connection fastening device provided by the utility model can also have the following additional technical characteristics: Specifically, the outer walls of two steel pipe poles are provided with spacing subassembly respectively, and wherein, spacing subassembly includes the stopper, and wherein, the stopper setting is on the steel pipe pole, and the spout has been seted up to the inner wall of connecting pipe, and the restriction groove has been seted up to the inner wall of connecting pipe. Specifically, the inner wall of the connecting pipe is provided with a baffle. Specifically, the outer walls of the two steel pipe rods are respectively provided with a mounting groove. Compared with the prior art, the utility model has the following beneficial effect that a spring steel sheet can be additionally arranged in the fastener. When the bolt is fastened, the spring steel sheet can generate elastic deformation, and continuous radial pressure is applied to the steel pipe rod, so that the gap between the steel pipe and the fastener can be eliminated, and additional clamping force can be provided, so that the connection is firmer and more reliable. Additional aspects and advantages of the utility model will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the utility model. Drawings The foregoing and/or additional aspects and advantages of the utility model will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings, in which: fig. 1 is a schematic structural view of a steel pipe pole connection fastening device according to an embodiment of the present utility model; Fig. 2 is a schematic structural view of a fastening assembly of a steel pipe pole connection fastening device according to an embodiment of the present utility model; fig. 3 is a schematic structural view of a limiting assembly of a steel pipe pole c
