Description

Improved quick self-locking hook

Technical Field

The application relates to the technical field of stage lamp accessories, in particular to an improved quick self-locking hook.

Background

The light environment is rendered by stage lamps in television studios, theaters, art studios, bars, mobile performance sites and other places. Because the stage lamps need to be adjusted frequently according to the performance content, the stage lamps are generally installed and fixed in a detachable mode, and the lamps are hung on the hanging rods or the trusses through the hooks.

The existing stage lamp installation generally comprises the steps that a hook body is connected with a lamp through a connecting device and then hung on a hanging rod or a truss, and the lamp installation mode generally comprises a hanging installation mode and a side-hanging installation mode. For two installation modes, the lamp is installed through the installation hooks, and the installation hooks are clamping installation structures surrounded by hook bodies, clamping plates and connecting bolts. The corresponding central angle of the partial circular arc of the rod body contacting the hook body must be less than 180 degrees, otherwise the rod body can not be inserted into the accommodating groove of the hook body. For the hook to be stable, the rod body must be clamped using a clamping plate. The locking mode of this kind of mounting structure is all more loaded down with trivial details, and locking structure is complicated, moreover in the installation, needs to spend certain time just can lock it, wastes time and energy.

The above technical problem of the prior art is solved by the invention patent No. 202111329528.X, which was previously filed by the applicant. However, the technical scheme of the patent application still has the problems that the structure of the safety piece is complex and the gasket of the self-locking piece is inconvenient to adjust.

Because the body of rod contact site of fixed shape is stronger than swing joint's from the locking part rigidity, the couple of rod contact site has been avoided bearing the gravity of the coupler body from the butt portion of locking part in the vertical line handing-over of coupler body focus, and the couple is more stable more durable.

And anti-skid grains are arranged on the adjusting part and the gasket of the self-locking piece. The antiskid lines can prevent the hook from rotating with the rod body.

The technical scheme provided by the application comprises the following beneficial effects:

1. oppress the adjustment portion from the locking part during the body of rod contact part of the body of hook of body of rod contact, rotate and hold the body of rod tightly from the butt portion of locking part, utilize the action of gravity to realize quick auto-lock.

2. The hook body is separated from the rod body when the safety piece is arranged to prevent the hook from accidentally bearing the upward supporting force, and safety is provided.

3. The safety piece is simple in structure, safe, reliable and convenient to operate.

4. The adjusting gasket of the self-locking piece is arranged on the abutting part, and the rigidity of the rod body contact part is increased.

Having described embodiments of the present application, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen in order to best explain the principles of the embodiments, the practical application, or improvements made to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
