Summary of the invention
The present invention mainly solves the technical matters existing for prior art, thus provide a kind of with self-locking structure, the deadweight of tubing is utilized to make suspender produce the power of larger compression tubing, safe and reliable, and only have a place to be connected with tubing, the tubing suspender of the band self-locking structure that the operating efficiency of workman is higher.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of tubing suspender with self-locking structure, comprise two claws and a hanging component, two described claw arranged crosswise, the middle part of described claw is provided with one first connecting bore, one end of described claw is provided with one second connecting bore, and the other end of described claw is provided with an arc grip block, and described hanging component comprises a vertical loading board, the lower end of described vertical loading board is provided with a connecting cylinder, and the first described connecting bore and described connecting cylinder are rotationally connected mutually.
As preferred embodiment of the present invention, described hanging component also comprises a lifting cylinder, described lifting cylinder and described vertical loading board sliding block joint, the both sides of described lifting cylinder are respectively arranged with a pair engaging lug, the tubing suspender of described band self-locking structure also comprises two connecting portions, and the two ends of described connecting portion are rotationally connected with described engaging lug and the second described connecting bore respectively.
As preferred embodiment of the present invention, the arranged outside of described arc grip block has a hold-down hook.
As preferred embodiment of the present invention, the upper end of described lifting cylinder is provided with a hanger, and the tubing suspender of described band self-locking structure also comprises suspension ring, and described suspension ring and described hanger are rotationally connected mutually.
The advantage of the tubing suspender of band self-locking structure of the present invention is: with self-locking structure, utilizes the deadweight of tubing to make suspender produce the power of larger compression tubing, safe and reliable, and only has a place to be connected with tubing, and the operating efficiency of workman is higher.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The advantage of the tubing suspender of band self-locking structure of the present invention is: with self-locking structure, utilizes the deadweight of tubing to make suspender produce the power of larger compression tubing, safe and reliable, and only has a place to be connected with tubing, and the operating efficiency of workman is higher.
As shown in Figure 1 and Figure 2, a kind of tubing suspender with self-locking structure, comprises two claws 1, hanging component, 2, two connecting portions 3 and suspension ring 4.
As shown in Figure 1, Figure 2, Figure 3 shows, these two claw 1 arranged crosswise, the middle part of this claw 1 is provided with one first connecting bore 11, one end of this claw 1 is provided with one second connecting bore 12, the other end of this claw 1 is provided with an arc grip block 13, and the arranged outside of this arc grip block 13 has a hold-down hook 131.Arranging this arc grip block 13 can enable the tubing suspender of this band self-locking structure better clamp tubing, arranging this hold-down hook 131 enables user use a rope to be connected by two arc grip blocks 13, improves the fiduciary level of the tubing suspender of this band self-locking structure further.
As shown in Figure 4, this hanging component 2 comprises vertical loading board 21 and a lifting cylinder 22, and this lifting cylinder 22 and this vertical loading board 21 sliding block joint, the lower end of this vertical loading board 21 is provided with a connecting cylinder 211, and the upper end of this lifting cylinder 22 is provided with a hanger 222.
As shown in Figure 1, Figure 2, Figure 4 shows, this first connecting bore 11 is rotationally connected mutually with this connecting cylinder 211, and the both sides of this lifting cylinder 22 are respectively arranged with a pair engaging lug 221, and the two ends of this connecting portion 3 are rotationally connected with this engaging lug 221 and this second connecting bore 12 respectively.When these two arc grip blocks 13 clamp tubing, under pulling force effect upwards, there is relative sliding in this lifting cylinder 22 and this vertical loading board 21, by the leverage of this connecting portion 3 and this claw 1, make this arc grip block 13 pairs of tubing apply larger pressure and reach self-locking effect, comparatively reliably.
