Description

Technical Field

[0001] This application relates to the technical field of stage light accessories, and particularly to a quick-clamping lamp hook. Background Art

[0002] During the installation of stage lights, the installation position of the lights will directly affect the projection effect of the light and the overall atmosphere of the stage. Usually, we install the lights on the lighting hanging brackets above the stage to ensure that the light can be evenly distributed and cover the entire stage. Therefore, the maintenance and adjustment of stage lights need to be considered.

[0003] Currently, for the installation of stage lights, generally, after connecting the hook body to the light through a connecting device, it is then hung on the hanging rod or truss. There are generally two installation methods for the lights: the hanging installation method and the side-hanging installation method. For both installation methods, the installation and fixation are achieved by clamping the rod body with a fixed hook and a movable hook that are hinged to each other on the lamp hook body.

[0004] The applicant recorded an innovative invention with a working principle different from the prior art in the applications No. 202310512480.9 and 202420406326.3, which can achieve the quick clamping installation of the lamp hook. However, in this application, the handle of the lamp hook and the safety mechanism are separately arranged up and down, and it cannot be operated with one hand. Summary of the Invention

[0005] To further optimize the structure of the lamp hook and make the lamp hook easy to operate, this application provides a quick-clamping device for the lamp hook.

[0006] The quick-clamping device for the lamp hook in this application includes a connecting block, and the connecting block is provided with a first hinge portion and a second hinge portion. The first end of a connecting rod is movably connected to the second hinge portion. One side of the connecting block extends to form a handle. The first hinge portion and the second end of the connecting rod are respectively connected to the fixed hook and the movable hook of the lamp hook body. Here, the fixed hook and the movable hook are relative concepts. The lamp hook body includes two movable hook bodies. If one is the fixed hook, then the other is the movable hook. Along the circumference of the hinge axis of the first hinge portion, the lamp hook body connected to the first hinge portion is provided with teeth. A stopper is hinged to the third hinge portion of the connecting block, and an elastic member is provided between the stopper and the connecting block to keep the stopper in a state of pressing against the teeth. The first hinge portion is provided with an avoidance position, so that when the connecting block swings, the projection of the connecting rod entering the first hinge portion will not interfere with the first hinge portion. The connecting rod is provided with a length fine-tuning mechanism for adjusting the effective length between the first end connection portion and the second end connection portion. The connecting rod is also provided with a tightening mechanism for maintaining the state after the effective length of the connecting rod is fine-tuned.

[0007] Preferably, the length fine-tuning mechanism includes a thread provided at one end of the connecting rod. The thread of the connecting rod can be connected to the hinge shaft. In some embodiments, it can also be connected to a nut after passing through the through-hole of the hinge shaft, which belongs to an equivalent structure. The tightening mechanism includes a spring sleeved on the connecting rod. One end of the spring abuts against the protrusion of the connecting rod, and the acting force of the spring restricts the rotation of the connecting rod. The protrusion can be a step with different shaft diameters, or a part such as a pin or a nut connected to the connecting rod. One end of the spring abuts against the protrusion of the connecting rod, and the other end abuts against the corresponding connecting component (hinge shaft or lamp hook body) of the connecting rod.

[0008] Preferably, one side of the stopper extends to form a push handle for rotating the stopper to release the locked state between the stopper and the tooth shape. When operating with one hand, the thumb presses the push handle of the stopper, and the other fingers pull the handle.

[0009] Preferably, the connecting block is a U-shaped part. The hinge shaft of the second hinge part passes through the U-shaped groove and is connected to the two side plates of the connecting block. The connecting rod extends into the U-shaped groove and is connected to the hinge shaft of the second hinge part. The two side plates of the connecting block of the first hinge part are respectively connected to the lamp hook body through two coaxial hinge shafts. The connecting block can be machined by cutting to form a U-shaped part, or formed by bending sheet metal. The U-shaped groove of the U-shaped part meets the requirement of the avoidance position for the connecting rod, and the connection of both side plates to the hinge shaft makes the force balanced.

[0010] Preferably, the axes of the second hinge part and the third hinge part coincide. At this time, the second hinge part and the third hinge part share a hinge shaft, which is more convenient for manufacturing.

[0011] The present application also discloses a lamp hook applying the above-mentioned quick clamping device. The lamp hook body includes a fixed hook and a movable hook hinged to each other at the fourth hinge part. A quick clamping device as described above is provided between the fixed hook and the movable hook. The first hinge part is provided at a position on the fixed hook deviating from the fourth hinge part, and the second end of the connecting rod is movably connected to a position on the movable hook deviating from the fourth hinge part.

[0012] Preferably, the second end of the connecting rod is hinged to the movable hook at the fifth hinge part, and the second end of the connecting rod is provided with a convex head and passes through the radial through-hole on the hinge shaft of the fifth hinge part.

[0013] The technical solution provided by the present application has the following beneficial effects:

[0014] The quick clamping device of the present application is applied to the lamp hook. When disassembling and assembling the lamp hook, one-handed operation can be realized. The thumb presses the stopper, and the other fingers pull the handle, which is very convenient. The threaded connection between the connecting rod and the hinge shaft can fine-tune the tightness of the clamping rod body and maintain the fine-tuned state through the pre-tightening force of the spring without chaos.
