Problems solved by technology

[0002] In the prior art, when connecting pipes, especially guardrails, there will be pre-punched holes, and it is often necessary to make connections at the pre-punched holes. However, conventional techniques such as screws and rivets cannot be used after the pre-punched holes are drilled. When installing connectors, it is often necessary to use long-span connectors to avoid the pre-punched holes for installation. In this way, the long-span connectors will inevitably be exposed to the outside of the pipe, resulting in extremely uncoordinated installation and affecting the appearance of the connection position. Secondly, It is easy to generate a connection gap at the connection position, and it is easy to loosen, which affects the strength of the pipe connection

Embodiment 1

[0027] Figure 1 to Figure 4 It shows the first embodiment of the fastening connection fitting for pipes with pre-punched holes according to the present invention. The pair of clamping feet 14 that are clamped by the punching hole 31, the part protruding out of the pre-punching hole 31 is tightly connected with the ordinary pipe 4 by tightening the top screw 2, and drives the pair of clamping feet 14 to expand and fasten the pre-punching hole 31. Its structure is simple and easy to install. When assembling, first insert the clip 14 on the joint 1 obliquely into the pre-punched hole 31 on the pre-punched pipe 3, so that the clip 14 and the pre-punched hole 31 form a buckle connection , and then another ordinary pipe 4 is inserted into the part of the joint 1 protruding out of the pre-punched hole 31, and the top screw 2 is tightened through the opening of the ordinary pipe 4 with a tool, so that it is contained in the ordinary pipe 4. The joint 1 expands to connect with the in...

Embodiment 2

[0035] Figure 5 to Figure 7 It shows the second embodiment of the fastening connection fittings for pipes with pre-punched holes of the present invention, the connection fittings are basically the same as the first embodiment, the only difference is that the clamp feet 14 are arranged on the pull plate 12 and the top plate 13 On the same side, both ends of the pull plate 12 and the top plate 13 are bent with a folded edge 15 for tightening the inner wall of the ordinary pipe 4, and are connected to the side plate 11 through the folded edge 15 at one end, and connected to the side plate 11 through the clamp on one side of the joint 1. The foot 14 connects the two pipes. When the top wire 2 is tightened, the folded edge 15 and the bent portion formed by the folded edge 15 and the side plate 11 will simultaneously tighten the ordinary pipe 4 that is sleeved outside the joint 1. Inner wall, in this structure, there is also no need to use large-span connectors to avoid the pre-pun...

Abstract

The invention discloses a fastening connection fitting for a pipe with a pre-punched hole, which includes a joint and a top wire. The part outside the pre-punched hole is tightly connected with the ordinary pipe by tightening the top screw, and drives the clip to expand and fasten the pre-punched hole. The utility model has the advantages of simple structure, convenient installation, elimination of installation gap and improvement of connection strength.

Description

technical field [0001] The invention mainly relates to the assembly technology of pipe connection, in particular to a fastening connection fitting for pipes with pre-punched holes. Background technique [0002] In the prior art, when connecting pipes, especially guardrails, there will be pre-punched holes, and it is often necessary to make connections at the pre-punched holes. However, conventional techniques such as screws and rivets cannot be used after the pre-punched holes are drilled. When installing connectors, it is often necessary to use long-span connectors to avoid the pre-punched holes for installation. In this way, the long-span connectors will inevitably be exposed to the outside of the pipe, resulting in extremely uncoordinated installation and affecting the appearance of the connection position. Secondly, It is easy to generate a connection gap at the connection position, and it is easy to loosen, which affects the strength of the pipe connection. Contents o...
