Description

High resistance to pull off flange joints

The new model relates to a joint, in particular to a high-resistance flange joint that is suitable for assembling a wave tube to a receiving part and can be used for cables to pass through.

In the installation process of many solar energy or electrical equipment, in order to avoid damage to the cable due to water seepage, dust, insects and ants or bites, the industry usually uses A wave tube is used to enclose and protect the periphery of the cable, so as to achieve the effects of waterproof, dust-proof and insect-proof. However, when the cable needs to pass through or merge to another large pipe fitting, guide groove, seat, box or box body, etc., it is necessary to use a flange joint to connect the wave tube to the container. One is installed on the wall.

Refer to Figures 1 and 2, a flange joint disclosed in Taiwan Patent No. I724975 is suitable for assembling a wave tube 11 to a mounting wall 12 and for at least one cable (not shown) to pass through. In the wave tube 11. The corrugated tube 11 has a tube outer surface 111 formed with external threads, and the mounting wall 12 has a mounting hole 121 corresponding to one end of the corrugated tube 11. The flange joint includes an inner sleeve 13, an outer sleeve 14, and two washers 15.

The inner sleeve 13 includes an inner sleeve wall 131 set on the periphery of the wave tube 11, and one end of the inner sleeve wall 131 extending into the mounting hole 121 protrudes radially outward and is correspondingly blocked by the mounting wall 12. A first ring wall 132 on one side, and a plurality of first outer screw portions 133 projecting radially inward from the inner sleeve wall 131 and screwed to the outer surface 111 of the wave tube 11. The outer sleeve 14 includes an outer sleeve wall 141 set on the outer periphery of the inner sleeve 13 and the wave tube 11, and one end of the outer sleeve wall 141 protrudes radially outward and is correspondingly blocked by the other of the mounting wall 12 The second ring wall 142 on the side and at least one second outer screw portion 143 projecting radially inward from the outer casing wall 141 and screwed to the outer surface 111 of the wave tube 11. The washers 15 are respectively cushioned between the first ring wall 132 of the inner sleeve 13 and the mounting wall 12, and between the mounting wall 12 and the second ring wall 142 of the outer sleeve 14, to improve waterproofing sex.

Although the flange joint uses the inner sleeve 13, the outer sleeve 14, and the washers 15 to lock the corrugated tube 11 on the mounting wall 12, the inner sleeve 13 and the outer sleeve 14 are bolted to the outside of the wave tube 11, the flange joint does not have any latches to fix the inside of the wave tube 11, so when the flange joint is used in special fields, such as port machinery, When offshore platforms, bridges, ships, offshore wind power and marine machinery...etc., due to strong wind or hydraulic pulling forces during use, the wave tube 11 may be deflected or detached from the flange joint, causing the at least A cable is exposed and easily corroded, so the design of the flange joint still needs to be improved.

Therefore, the purpose of the present invention is to provide a flange joint with high resistance to pull-off which can overcome at least one of the disadvantages of the prior art.

Therefore, the novel high-resistance pull-off flange joint is suitable for assembling a wave tube to a mounting wall. Outside of the pipe, the mounting wall has a first wall surface and a second wall surface spaced apart, and a mounting hole connecting the first wall surface and the second wall surface. The high-resistance flange joint includes an inner sleeve, An outer sleeve, and a strong cylinder.

The inner sleeve includes an inner sleeve wall extending along a central axis and sleeved on the periphery of the wave tube, and a second inner sleeve wall protruding radially outward from one end of the inner sleeve wall and correspondingly blocked by the mounting wall The first ring wall of the wall surface, and at least one first outer screw portion protruding radially inward from the inner sleeve wall and screwed to the outside of the tube of the wave tube.

The outer sleeve includes an outer sleeve wall extending along the central axis and sleeved on the periphery of the inner sleeve and the wave tube, and an outer sleeve wall protruding radially outward from an end of the outer sleeve wall adjacent to the first ring wall, and correspondingly blocking The second ring wall stops at a side of the first ring wall away from the second wall surface, and at least one second outer screw portion protruding radially inward from the outer casing wall and screwed to the outside of the tube of the wave tube.

The strong cylinder includes an inner screw wall extending along the central axis and penetrating the inner circumference of the wave tube, and one end of the inner screw wall extending into the mounting hole protrudes radially outward, and correspondingly stops at the mounting hole. The screw head wall of the first wall surface of the wall, and at least one inner screw part protruding radially outward from the inner screw wall and screwed to the inner surface of the tube of the wave tube.

The effect of the new model is that the high-resistance pull-off flange joint can be locked and fixed to the inner side of the wave tube through the design of the strong cylinder, so the pull-off resistance can be improved.
