Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel pipe poles, and in particular to a steel pipe pole connection and fastening device. Background Technology
[0002] Steel pipe poles are support poles made of steel pipes, commonly found in power line towers, streetlights, construction scaffolding, etc. They are commonly used pole materials in the fields of power, communications, and construction. During use, because the length of a single steel pipe is limited, it is often necessary to fasten the steel pipes together to adapt to the length requirements of steel pipe poles in different scenarios. In the process of connecting them, fasteners are often used to fix the two steel pipe poles.
[0003] However, since the outer diameter of the steel pipe is usually smaller than the inner diameter of the fastener, even after the bolts are tightened, it often only prevents the steel pipe from separating from the fastener, but cannot completely eliminate the gap between them. This loose fit can lead to the risk of loosening at the connection, making it prone to swaying under stress. (For example, in construction scaffolding, if there are gaps at the steel pipe connections, it may lead to a decrease in the stability of the scaffolding, posing a risk of falls for construction workers.) Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.
[0005] Therefore, one objective of this utility model is to provide a steel pipe rod connection and fastening device. By setting a spring steel plate between the fasteners, when bolts are used for fastening, the spring steel plate deforms and compresses the steel pipe rod, making the steel pipe rod and the fasteners more secure and less prone to shaking.
[0006] To achieve the above objectives, the first aspect of this utility model proposes a steel pipe rod connection and fastening device, comprising: a connecting pipe, two steel pipe rods, and a fastening assembly, wherein the two steel pipe rods are slidably connected to both ends of the connecting pipe, the fastening assembly is disposed on the connecting pipe, and the fastening assembly includes a spring steel plate and two bolts, wherein the outer wall of the connecting pipe has a connecting groove, the spring steel plate is installed in the connecting groove, the outer wall of the spring steel plate has two fixing holes, the outer walls of the two steel pipe rods are respectively provided with threaded holes, and the two bolts pass through the corresponding fixing holes and are threadedly connected to the corresponding threaded holes.
[0007] In addition, the steel pipe rod connection and fastening device proposed above according to this utility model may also have the following additional technical features:
[0008] Specifically, the outer walls of the two steel pipe poles are respectively provided with limit components, wherein the limit components include limit blocks, wherein the limit blocks are set on the steel pipe poles, and the inner wall of the connecting pipe is provided with a sliding groove and a limiting groove.
[0009] Specifically, a baffle is provided on the inner wall of the connecting pipe.
[0010] Specifically, the outer walls of the two steel pipe poles are respectively provided with mounting grooves.
[0011] Compared with the prior art, this utility model has the following advantages: a spring steel sheet can be added inside the fastener. When the bolt is tightened, the spring steel sheet will undergo elastic deformation, applying continuous radial pressure to the steel pipe rod. This can eliminate the gap between the steel pipe and the fastener, and also provide additional clamping force, making the connection more secure and reliable.
[0012] Additional aspects and advantages of this invention 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 invention. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0019] The steel pipe pole connection and fastening device of this utility model embodiment is described below with reference to the accompanying drawings.
[0020] like Figures 1-3As shown, the steel pipe rod connection and fastening device of this utility model embodiment includes: a connecting pipe 1, two steel pipe rods 2 and a fastening assembly 3.
[0021] Two steel pipe rods 2 are slidably connected to both ends of the connecting pipe 1, and fastening components 3 are installed on the connecting pipe 1.
[0022] Fastening assembly 3 includes a spring steel sheet 32 and two bolts 35.
[0023] The outer wall of the connecting pipe 1 is provided with a connecting groove 31.
[0024] The spring steel sheet 32 is installed in the connecting groove 31. Two fixing holes 33 are opened on the outer wall of the spring steel sheet 32. The outer walls of the two steel pipe rods 2 are respectively provided with threaded holes 34. The two bolts 35 pass through the corresponding fixing holes 33 and are threadedly connected to the corresponding threaded holes 34.
[0025] It should be noted that, given that the inner diameter of the connecting pipe 1 is a fixed size, in the structure described in this embodiment, when the spring steel sheet 32 is placed in the connecting groove 31 and is in its natural state, it will extend inward toward the connecting pipe 1. Due to this characteristic, when the steel pipe rod 2 is inserted into the connecting pipe 1, a compressive force is applied to the spring steel sheet 32, causing the spring steel sheet 32 to deform and move outward toward the connecting pipe 1. This movement mechanism effectively enhances the tightness of the connection between the connecting pipe 1 and the steel pipe rod 2.
[0026] Specifically, when connecting the two steel pipe rods 2, the workers install the two steel pipe rods 2 at both ends of the connecting pipe 1 respectively, and then pass the two bolts 35 through the corresponding fixing holes 33 and thread them into the corresponding threaded holes 34. During the tightening of the bolts 35, the head of the bolts 35 will squeeze the spring steel sheet 32, causing the spring steel sheet 32 to deform and squeeze the steel pipe rod 2, thereby eliminating the gap between the steel pipe rod 2 and the connecting pipe 1, making the connection more firm and reliable.
[0027] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the outer walls of the two steel pipe rods 2 are respectively provided with limit components 4, and the inner wall of the connecting pipe 1 is provided with baffles 5.
[0028] The limiting component 4 includes a limiting block 41, which is set on the steel pipe rod 2. The inner wall of the connecting pipe 1 is provided with a sliding groove 42, a limiting groove 43, and a baffle 5.
[0029] Specifically, when connecting the steel pipe rod 2, the worker aligns the limiting block 41 with the sliding groove 42 and pushes the steel pipe rod 2 so that the steel pipe rod 2 slides on the inner wall of the connecting pipe 1. When one end of the steel pipe rod 2 touches the baffle 5, the steel pipe rod 2 is then rotated so that the steel pipe rod 2 drives the limiting block 41 into the limiting groove 43. This ensures that the steel pipe rod 2 will not detach from the connecting pipe 1 under the action of the limiting block 41.
[0030] In one embodiment of this application, such as Figure 2 As shown, the outer walls of the two steel pipe rods 2 are respectively provided with mounting grooves 6.
[0031] It is understood that the mounting groove 6 described in this embodiment allows the head of the bolt 35 to enter the mounting groove 6 when the bolt 35 is tightened, so that the bolt 35 does not protrude and is more aesthetically pleasing.
[0032] In summary, a spring steel plate can be added inside the fastener. When the bolt is tightened, the spring steel plate will undergo elastic deformation, applying continuous radial pressure to the steel pipe rod. This can eliminate the gap between the steel pipe and the fastener, and also provide additional clamping force, making the connection more secure and reliable.
