Stir the locating part so that stop part breaks away from the locking hole, then the reverse rotation jib can be with jib and hanging the first separation, the dress of joining in marriage between jib and the hanging head is comparatively convenient with the separation, and need not be with the help of the instrument, convenient operation.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is an exploded view of the present invention;

fig. 3 is a schematic structural view of the suspension head from another view.

Detailed Description

Referring to fig. 1 to 3, the utility model relates to a suspender connection structure, it includes jib 1 and hangs head 2, hang and be provided with connecting cylinder 21 on the head 2, have the external screw thread on jib 1's the lateral wall, have the internal thread on connecting cylinder 21's the inside wall, jib 1 can hang head 2 corotation relatively in order to install jib 1 in connecting cylinder 21 to realize jib 1 and hang the joining in marriage dress between the head 2. The outer side wall of the suspender 1 is provided with a locking hole 11, the connecting cylinder 21 is provided with a limiting part 3, the limiting part 3 is provided with a clamping part 31, and the clamping part 31 is positioned in the locking hole 11 and can limit the suspender 1 to reversely rotate relative to the hanging head 2 so as to avoid the suspender 1 from rotating and loosening relative to the hanging head 2.

Referring to fig. 2, the stopper 3 is sheet-shaped, and the stopper 3 is bent to form the locking portion 31. The structure of the limiting piece 3 can be simplified, and the production cost can be reduced.

The connecting cylinder 21 is provided with a mounting groove 211, and the stopper 3 is located in the mounting groove 211. The mounting groove 211 can support and protect the limiting member 3, thereby preventing the limiting member 3 from being irreversibly deformed due to stress.

The distance that the engagement portion 31 extends into the lock hole 11 gradually increases in the normal rotation direction of the boom 1, so that a guide surface facing the boom 1 is formed on the engagement portion 31. By the structure, when the suspender 1 and the hanging head 2 need to be assembled, the suspender 1 is rotated in the forward direction, the side wall of the suspender 1 can push and press the guide surface to enable the clamping part 31 to leave the inner cavity of the connecting cylinder 21, even if the limiting part 3 is not pulled by hands, the suspender 1 can rotate forwards smoothly, and the operation is convenient; and when needs are separated jib 1 and hanging head 2, the jib 1 that needs to reverse, and the lateral wall butt locking hole 11 of clamping part 31 this moment's lateral wall needs the staff to stir locating part 3, makes clamping part 31 break away from locking hole 11, and jib 1 just can smoothly reverse this moment, can improve from this the utility model discloses a security.

The stopper 3 may be rod-shaped, and the rod-shaped stopper 3 may be bent to form the locking portion 31.
