Problems solved by technology

However, the elbow pipe or tee pipe in the prior art has no anti-rotation structure, and the elbow pipe or tee pipe can rotate freely relative to the mounting plate and loosen, resulting in poor sealing at the junction of the elbow pipe or tee pipe and the mounting plate , it may even cause the elbow or tee to fall off the mounting plate, and the reliability is low
In addition, when the elbow pipe or tee pipe in the prior art is connected to the mounting plate with a through hole, it must be fixed on the mounting plate through an adapter conduit, so when sealing is required, now There are two sections of sealing between the elbow or tee pipe and the transfer conduit and between the transfer conduit and the mounting plate in the prior art. Because there is no anti-rotation structure in the prior art, the sealed connection is easy to cause The looseness between the elbow pipe or the tee pipe and the mounting plate causes the seal to fail, and the reliability is low

Embodiment 1

[0024] Embodiment one: if Figure 1 ~ Figure 4 As shown, a through pipe connection structure provided by the embodiment of the present invention is used for the detachable fixed connection between the through pipe 100 and the mounting plate 200 with the through hole 201. The through pipe 100 can be a straight pipe or an bent through pipe. , T-shaped pipe, three-way pipe or multi-way pipe, etc. In this embodiment, it is applied to the lead-in device of a lamp. The inner cavity of the lamp is provided with a light source, the through pipe 100 is set as a bent through pipe, and the mounting plate 200 is fixed to the lamp through a locking member (not shown in the figure). on the casing. In addition, the mounting plate 200 can also be integrally formed with the housing of the lamp. The through pipe 100 includes a tube tube 110 that can be inserted into the through hole 201. One end of the tube tube 110 is inserted into the through hole 201, and this end is provided with an exter...

Embodiment 2

[0031] As an alternative to the above-mentioned embodiments of the present invention, such as Figure 6 As shown, the anti-rotation flange 130 is polygonal, and the anti-rotation raised portion 210 is matched with at least one side of the anti-rotation flange 130. In the specific structural design, the anti-rotation flange 130 can be Designed as a non-circular shape, the anti-rotation raised portion 210 surrounds or partially surrounds the anti-rotation flange 130 , when the through pipe 100 is plugged in place, the anti-rotation flange 130 will be constrained by the anti-rotation raised portion 210 , The through pipe 100 cannot rotate relative to the mounting plate 200 arbitrarily, which ensures the reliability of the seal and good product reliability.

Embodiment 3

[0033] As another alternative to the above-mentioned embodiment of the present invention, such as Figure 7 As shown, the anti-rotation protrusion 210 is columnar, and the anti-rotation flange 130 is provided with at least one through hole 102 matching the anti-rotation protrusion 210, and the anti-rotation protrusion 210 passes through the The hole 102 is sleeved on the anti-rotation flange 130. When the through pipe 100 is plugged in place, the through hole 102 on the anti-rotation flange 130 will be sleeved on the anti-rotation raised part 210, so that the anti-rotation flange 130 is protected against rotation. The constraint of the rotating boss 210 prevents the through pipe 100 from rotating relative to the mounting plate 200 arbitrarily, which ensures the reliability of the seal and good product reliability.

Abstract

The invention is applied to the field of connection structures, and discloses a through pipe connection structure, which is used for detachably and fixedly connecting a through pipe and a mounting plate with a through hole. The through pipe comprises a pipe barrel which can be inserted into the through hole; one side, from which the pipe barrel is inserted, of the mounting plate is provided with an anti-rotation bump in a protruding way; an anti-rotation flange is protruded outside the pipe barrel; and when the pipe barrel is inserted into the mounting plate, the anti-rotation flange can be clamped and fixed at the anti-rotation bump. Particularly, the tail end of the pipe barrel is provided with outside threads and is sleeved with a nut; and the nut is positioned on the other side of the mounting plate. As the anti-rotation flange is protruded on the through pipe and the corresponding anti-rotation bump is protruded on the mounting plate, the through pipe connection structure provided by the invention can effectively prevent the bad phenomenon of the random rotation, relative to the mounting plate, of the through pipe, and solve the technical problems of the easy loosening and unreliable sealing of the through pipe without an anti-rotation structure in the prior art.

Description

technical field [0001] The invention belongs to the field of connecting structures, and in particular relates to a through-pipe connection structure for connecting a through-pipe to a mounting plate with a through-hole. Background technique [0002] In the occasions where turning or T-shaped connection is required when installing the structure, the application of elbow or tee pipes has become quite common. direction connection. However, the elbow pipe or tee pipe in the prior art has no anti-rotation structure, and the elbow pipe or tee pipe can rotate freely relative to the mounting plate and loosen, resulting in poor sealing at the joint between the elbow pipe or tee pipe and the mounting plate , It may even cause the elbow or tee to fall off the mounting plate, and the reliability is low. In addition, when the elbow pipe or tee pipe in the prior art is connected to the mounting plate with a through hole, it must be fixed on the mounting plate through an adapter conduit,...
