Description

Technical Field

[0001] This utility model relates to the technical field of pole installation equipment, and in particular to a pole connection device. Background Art

[0002] When installing communication, power, or other equipment located in the outside and at a high altitude, poles are used to assist in the installation of cables and other equipment. Construction workers install poles in the towers and install fixed pulleys, movable pulleys, and other transmission equipment at the top of the poles. With the support of the poles, the objects to be installed are pulled up to the towers by ropes for assembly.

[0003] Since the uprights of poles are mostly made of round steel, and the branches of poles are generally extended using angle steel, the fastener structures for round steel and angle steel poles are different, making the procurement of fasteners for pole installation cumbersome. In addition, to meet the needs of the installation site, there are usually vertical or horizontal pole installation requirements. The common pole installation fasteners also have a fixed distribution structure, and different accessories are required depending on different installation requirements, making them quite troublesome to use.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figures 1-6 In this embodiment of the utility model, a pole-mounting connection device includes a mounting frame and a pole-mounting fixing assembly. The mounting frame includes a first fastener 1 and a second fastener 2 arranged opposite to each other, and a fastener that can connect and fasten the first fastener 1 and the second fastener 2. The first fastener 1 and the second fastener 2 are respectively provided with V-shaped bayonet 3 on opposite sides. The second fastener 2 is provided with a V-shaped protrusion 4 on the side away from the first fastener 1. The pole-mounting fixing assembly includes a support arm 5, a fixing member, a first bolt 6, and a first nut 7. The first fastener 1 is provided with a connecting protrusion 8 on the side away from the second fastener 2. The connecting protrusion 8 is provided with a first through hole 9 around its surface. The support arm 5 is provided with a second through hole 10 near its end. The first bolt 6 passes through the first through hole 9 and the second through hole 10 and is threadedly connected to the first nut 7. The fixing member is detachably mounted on the support arm 5 for fixing the pole 23.

[0025] It should be noted that the mounting bracket of this utility model has two installation methods; see reference. Figures 3-4 When connecting to angle steel 21, the V-shaped latch 3 of the first fastener 1 is engaged with the outside of angle steel 21, and the V-shaped protrusion 4 of the second fastener 2 is engaged with the inside of angle steel 21. Then, the first fastener 1 and the second fastener 2 are fastened together using fasteners. (See also...) Figures 5-6When connecting with round steel 22, the V-shaped latches 3 on the first fastener 1 and the second fastener 2 are respectively engaged with the two sides of the round steel 22, so that the two sides of the opening of the V-shaped latches 3 are tangent to the surface of the round steel 22. Then, the first fastener 1 and the second fastener 2 are fastened together by fasteners. Since the V-shaped latches 3 are used, no matter how the size of the round steel 22 changes, as long as the round steel 22 can contact the V-shaped latches 3 on the first fastener 1 and the second fastener 2 to bear force, it can be used. In this way, a universal clamping connection for angle steel 21 or round steel 22 can be achieved, improving convenience and practicality.

[0026] To facilitate the installation and disassembly of the first fastener 1 and the second fastener 2, the fasteners include a second bolt 11 and a second nut 12. The first fastener 1 has a third through hole 13, and the second fastener 2 has a fourth through hole 14 corresponding to the third through hole 13. The second bolt 11 passes through the third through hole 13 and the fourth through hole 14 and is threadedly connected to the second nut 12.

[0027] The fastener includes a U-shaped rod 15 and a third nut 16. Several fifth through holes 17 are provided on the support arm 5 along its length. The two ends of the U-shaped rod 15 are threaded. The two ends of the U-shaped rod 15 pass through two of the fifth through holes 17 and are threaded to the third nut 16. During installation, the retaining rod 23 is inserted into the U-shaped rod 15 and then the third nut 16 is tightened to fix the retaining rod 23 on the support arm 5.

[0028] Support arm 5 is a semi-enclosed structure formed by top plate 18 and side plates 19. The first through hole 9 and the fifth through hole 17 are both located on top plate 18. The semi-enclosed structure of support arm 5 allows for better contact with the connecting protrusion 8, resulting in a more secure connection between support arm 5 and the first fastener 1. (See reference...) Figures 3-6 Since the first through hole 9 is provided around the surface of the connecting protrusion 8, that is, on its top, left, right and bottom surfaces, during the installation process, the top plate 18 can be attached to the top of the connecting protrusion 8 or to the left and right sides of the connecting protrusion 8, so that the U-shaped rod 15 is set horizontally or vertically to adapt to the installation requirements of vertical or horizontal rods.

[0029] To facilitate inserting both ends of the U-shaped rod 15 into the fifth through hole 17 and to facilitate adjusting the installation position of the U-shaped rod 15, the fifth through hole 17 is an oblong hole.

[0030] The V-shaped protrusion 4 has a notch 20, which divides the V-shaped protrusion 4 into two parts, left and right. The two parts of the V-shaped protrusion 4 can be brought together or expanded under the action of external force. After the first fastener 1 and the second fastener 2 are installed on the angle steel 21 or the round steel 22, the V-shaped protrusion 4 will undergo elastic deformation, so that the first fastener 1 and the inner side of the angle steel 21 or the outer side of the round steel 22 are completely fitted together, so that the device can be fixed for a long time and is difficult to loosen.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
