Example one

Referring to fig. 1 and 2, the utility model is a hanger for producing and transporting copper tubes, comprising two L-shaped claw arms 1 arranged oppositely and two connecting rods 2; the middle parts of the two claw arms 1 are coaxially hinged; the upper ends of the two claw arms 1 are hinged with connecting rods 2; the upper ends of the two connecting rods 2 are hinged through a pin 21. The pin shaft 21 is connected with a hanging ring for connecting with a travelling crane through a rope.

As shown in fig. 3, one of the claw arms 1 is welded with a positioning plate 3 which is horizontally arranged; the positioning plate 3 is provided with a straight notch 301, and the straight notch 301 is vertically arranged relative to the pin shaft 21.

The pin shaft 21 is rotatably connected with the connecting seat 4, a through hole is formed in the connecting seat 4, and the pin shaft 21 penetrates through the through hole to be connected with the connecting seat 4. The lower end of the connecting seat 4 is provided with a connecting hole, and a lock column 5 is in clearance fit in the connecting hole. The side wall of the connecting seat 4 is provided with a threaded through hole, and is in threaded connection with a guide pillar.

An annular channel 501 is formed on the peripheral side surface of the lock cylinder 5; the inner top surface and the inner bottom surface of the annular channel 501 are uniformly provided with zigzag limiting grooves 502, and the limiting grooves 502 arranged on the inner top surface and the inner bottom surface are staggered by 45 degrees. The lower end of the lock column 5 is fixedly connected with a connecting column 503 which is in clearance fit with the straight notch 301, and the connecting column 503 and the lock column 5 can be connected by welding or have an integrated stepped shaft structure. The lower end of the connecting column 503 is welded with a locking block 504; the locking block 504 has a length greater than the width of the slot 301 and a width less than the width of the slot 301. The end of the guide post 401 extends into the connecting hole and is matched with the limiting groove 502 for enabling the lock cylinder 5 to rotate circularly through the axial movement of the lock cylinder 5. Specifically, when the hanger needs to be taken out from the copper pipe frame, the position of the pin shaft 21 is pressed down, and the locking block 504 at the lower end of the locking column 5 is parallel to the length direction of the straight notch 301 on the positioning plate 3 at the moment and corresponds to the position.

The pin shaft 21 is pressed down continuously, the locking block 504 penetrates through the straight notch 301, the lock cylinder 5 is pushed up through the positioning plate 3, at the moment, the guide column is abutted against the inclined surface of the lower limiting groove 502, and the lock cylinder 5 is made to rotate circularly in the extrusion process, when the guide post is clamped into the lower limit groove 502 and can not move, the positioning plate 3 is far away from the lock cylinder 5 at the position of the upward-lifting pin shaft 21, at the moment, the lock cylinder 5 moves downwards under the action of gravity, so that the inclined plane of the upper limit groove 502 is matched with the guide post and rotates in the process of moving the lock cylinder 5 downwards, because the limit groove 502 arranged on the inner top surface of the limit groove 502 and the limit groove 502 arranged on the inner bottom surface are staggered by 45 degrees, the lock cylinder 5 rotates 90 degrees circumferentially in the process of the up-and-down reciprocating movement of the lock cylinder 5, that is, the locking block 504 and the straight slot 301 are perpendicular to each other, and the position between the pin 21 and the positioning plate 3 is limited, so that the claw arm 1 and the connecting rod 2 cannot rotate.

At the moment, the lower ends of the two claw arms 1 are in a combined state, so that the two claw arms can be taken out from the grabbing holes in the copper pipe frame conveniently. When needing to lift by crane the copper pipe support, insert claw arm 1 lower extreme at this state and snatch downthehole, push down round pin axle 21 position, as above-mentioned process, lock 5 circumference rotates 90 for locking block 504 rotates to with rabbet 301 parallel state, thereby during the pull-up rings, relative initiative between claw arm 1 and connecting rod 2, locating plate 3 is kept away from gradually to round pin axle 21, makes the lower extreme of two claw arms 1 turn up, blocks and snatchs the hole, thereby realizes lifting by crane of copper pipe support.

Example two

On the basis of the first embodiment, the cross-sectional shape of the locking block 504 is a tapered structure, so that the locking block 504 can better pass through the straight notch 301.

Meanwhile, as shown in fig. 6 and 7, the claw arm 1 includes two arm plates 101 arranged side by side; the upper ends of the two arm plates 101 are fixedly inserted with a shaft sleeve 102, and the lower ends of the two arm plates are welded with a lining plate 103 for grabbing the copper pipe frame through the lining plate 103. The connecting rod 2 is composed of two connecting side plates 201 arranged side by side; the connecting side plate 201 is rotatably connected with the bushing 102.

And, the connecting seat 4 is located between the two connecting side plates 201 of the connecting rod 2; one side of the connecting seat 4 is fixedly connected with a connecting block 401; the lateral plate 201 is inserted with a pin rod 402 penetrating through the connecting block 401, so that the connecting block 401 is connected with the lateral plate 201, the connecting seat 4 is prevented from shaking in the using process, the locking block 504 is prevented from being inserted into the straight groove opening 301, and the convenience in use is improved.
