Joint structure for quickly connecting corrugated pipe
Joint structure for quickly connecting corrugated pipe
A joint structure for connecting a corrugated pipe to a fixed part includes a main body, a packing screw cap, and a clamping claw. The clamping claw is sandwiched between the main body and the packing screw cap. The clamping claw defines a through slot at an edge thereof to make the clamping claw can enlarge an inside diameter thereof. A plurality of inner claws is formed at the edge of the clamping claw.
A corrugated pipe is a kind of hollow pipe for protecting a cable from damage caused by entering of foreign matter such as percolating water, ants, dust, and so on. In order to follow a bend and distortion of the cable during its disposing, andto increase an agility and retractility of the corrugated pipes, annular bulgy portions and annular concave portions are alternately formed at an out edge of the corrugated pipe. Taiwan Patent No. 511816 which is named "improved joint of wire protecting pipe", and Taiwan Patent No. 449169 which is named "jointstructure for quickly connecting wire protecting pipe". These patents can connect the plastic container to the fixed part. However, they have different problems as follow.
Firstly, for example, a limiting element in Taiwan Patent No. 295317 only utilize a barb to clasp a depressed portion of the stackable plastic containers without any astricting effect. Therefore, the protecting pipe is easily loosed when an outside force isapplied thereto.
Secondly, for example, though Taiwan Patent No. 449169 can quickly assemble and disassemble the protecting pipe, its action is not assured. A loose can be caused by a mistaken touch. At the same time, the joint structure cannot effectivelyresist a pull of an outside force, and the structure thereof is complicated.
Finally, for example, a pressing block of Taiwan Patent No. 511816 is pivotally assembled separately. The pressing block cannot be formed integratively, so it needs to be assembled. Further, the pressing block is not easy to be machined. Inaddition, the joint's action is also not assured.
As can be known from the above description, the disclosed or used corrugated pipes joint have problems of deficient clamping force or bad waterproof capability, separately or together. At the same time, a problem of inconvenient detachability isfurther existed.
