Description

Technical Field

[0001] The present application relates to the technical field of stage light accessories, and particularly relates to a rod body loop device. 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 frame 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, the hook body is connected to the light through a connecting device and then hung on the suspension 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 of the lights is achieved through an installation hook, and the installation hook has a clamping installation structure surrounded by a hook body, a clamping plate, and a connecting bolt. First, the rod body is inserted into the receiving groove of the hook body, and then the nut is rotated to contract the clamping plate to clamp the rod body. The locking methods of this installation structure are relatively cumbersome, the locking structure is complex, and it takes a certain amount of time to lock it during the installation process, which is time-consuming and laborious. Summary of the Invention

[0004] To overcome the problems existing in the related art, the present application provides a rod body loop device, which is easy to install, has stronger adaptability, and is suitable for installation surfaces of various shapes and materials. It is more convenient for lights that need to be frequently replaced in position or angle, and has a high safety factor.

[0005] The present application provides a rod body loop device, including a loop body. The loop body includes a first loop portion and a second loop portion hinged through a first hinge portion. A connecting portion is arranged between the first loop portion and the second loop portion. The first loop portion, the second loop portion, and the connecting portion are connected end to end to form a rod body receiving space for clamping the rod body. The first end of the connecting portion and the second loop portion are hinged at a second hinge portion deviating from the first hinge portion. The second end of the connecting portion and the first loop portion are clamped at a card slot deviating from the first hinge portion. The connecting portion includes an adjusting mechanism for adjusting the distance between the second hinge portion and the card slot.

[0006] Preferably, the connecting part includes a connecting block which is hinged to the second hinge part. The first end of the connecting rod is clamped in the clamping groove. The second end of the connecting rod is hinged to the connecting block at a third hinge part which is located at a position deviating from the second hinge part. The second hinge part is provided with an avoidance position so that when the connecting block swings, the projection of the connecting rod entering the second hinge part will not interfere with the hinge shaft of the second hinge part. One side of the connecting block extends to form a handle. A locking mechanism is arranged between the buckle body and the connecting block for restricting the relative movement between the buckle body and the connecting block. The connecting part includes a three-point movable connection of a clamping groove, a second hinge part and a third hinge part. When the second hinge part is located in the middle of the connection line between the clamping groove and the third hinge part, the distance between the second hinge part and the clamping groove is the shortest, and it can be set to the state of clamping the rod body. The locking mechanism is used to maintain the clamping state. When the second hinge part deviates, the clamping of the rod body is released. All the operations of clamping or releasing can be realized by rotating the handle, and the operation is very simple.

[0007] Preferably, the locking mechanism includes a tooth shape arranged on the buckle body and a stopper arranged on the connecting block; the tooth shape is arranged on the circumference of the hinge shaft of the second hinge part; the stopper is hinged to the connecting block and is provided with an elastic component (not marked in the drawing, usually it can be a torsion spring or other similar elastic components) to keep the stopper in a state of pressing tightly against the tooth shape. One side of the stopper extends to form a push hand for rotating the stopper to release the locking state between the stopper and the tooth shape. When clamping the rod body, rotate the handle, and the stopper automatically presses tightly against the tooth shape. When releasing the rod body, press the push hand with the thumb and rotate the handle with other fingers, and single-hand operation can be realized. The convenience brought by this locking mechanism is not possessed by any lamp hook on the current market. In some other embodiments, the locking mechanism includes a movable buckle arranged on the connecting block and a fixed buckle arranged on the buckle body corresponding to the movable buckle, and the locking effect can also be realized.

[0008] Preferably, a length fine-tuning mechanism is arranged on the connecting rod for adjusting the effective length between the clamping groove and the third hinge part; a tightening mechanism is also arranged for maintaining the state of the connecting rod after fine-tuning. By finely adjusting the effective length of the connecting rod, the clamping force when rotating the handle can be in an optimal state. Especially when the diameter of the rod body is unstable or worn, the function of the length fine-tuning mechanism is very obvious, and the applicable range of the rod body buckle device can be improved. The tightening mechanism can maintain the state of the connecting rod after fine-tuning and will not change during transportation or repeated operations, which can greatly improve the installation efficiency. Specifically, the first end of the connecting rod is provided with a convex head with a diameter larger than that of the clamping groove, and is clamped outside the clamping groove. The second end of the connecting rod is provided with a threaded part connected to the hinge shaft of the third hinge part. A spring is sleeved on the threaded part, with one end abutted against the connecting rod and the other end abutted against the hinge shaft of the third hinge part. The spring is installed at the second end of the connecting rod and will not interfere with the operation of the clamping groove. Further, a protruding part is arranged outside the clamping groove for preventing the convex head of the connecting rod from slipping off, and the safety factor can be provided.

[0009] Preferably, a clamping block is hingedly connected to the inner side of the middle section of the second buckle part, and the inner side of the clamping block is provided with an arc surface, and the outer side of the bottom of the arc surface is hingedly connected to the second buckle part, and the clamping block can swing around the hinge axis. The setting of the clamping block can greatly increase the applicable range of rods with different diameters. When clamping, the clamping block automatically adjusts the center position of the arc surface, so that the force on the rod is more balanced.

[0010] Preferably, the first buckle portion is used as a fixing member of the buckle rod body, and forms a hook shape between the first hinge portion and the slot, and a lamp connecting portion is provided below the first hinge portion, and the first buckle portion can hang the lamp on the rod body under the action of gravity. The rod buckle device can be hung on the rod body before clamping, so that a single person does not need the assistance of others, and the operation is simple.

[0011] The technical solution provided by this application includes the following beneficial effects:

[0012] A rod body buckle device adopts a buckle design, which is fixed on the rod body by squeezing or loosening, and realizes 360° full encirclement of the rod body, and will not be unhooked, with a high safety factor. The connecting part and the first buckle part are connected by a snap connection, which is easy to unfasten the connecting part before hanging, and will not hinder the entry of the rod body; the connecting part is easy to close after hanging, and the installation is simple. The spacing between the second hinged part and the card slot is adjusted by the adjustment mechanism, and the first buckle part and the second buckle part quickly clamp the rod body, which is easy to operate.
