Description

Technical Field

[0001] The utility model relates to the field of projection equipment, in particular to an anti-falling structure and an anti-falling bracket. Background Art

[0002] The use of projection equipment is becoming more and more widespread. When using the projection equipment, it is generally necessary to fix it on the ceiling through the projection equipment ceiling bracket. CN208579136U Chinese utility model patent discloses a simple ceiling bracket for a projector, including a ceiling plate and a suspension rod. One end of the suspension rod is connected to the ceiling plate, and also includes a fixed cover, a movable cover, a non-slip plastic ring, and a connecting part. The other end of the suspension rod is connected to the fixed cover. The fixed cover and the movable cover are cooperatively connected to form an inner cavity matching the non-slip plastic ring. The non-slip plastic ring is located in the inner cavity. The connecting part includes a ball head and a connecting rod. The ball head is fixedly connected to one end of the connecting rod. The ball head is arranged in the inner cavity. The non-slip plastic ring is sleeved on the surface of the ball head. The non-slip plastic ring holds the ball head tightly, so that the projection angle of the projector can be fixed, and the projection angle of the projector can be quickly adjusted.

[0003] In the above technical solution, during the process of adjusting the projection angle of the projector, the slippery plastic ring will loosen the ball head. The weight of the projection device may easily cause the ball head to separate from the cavity formed by the fixed cover, the movable cover and the anti-slip plastic ring, causing the projection device to fall and damage the projection device, which is very dangerous. Utility Model Content

[0004] The utility model provides an anti-falling structure to solve the technical problem that a projection device may fall, which can effectively prevent the projection device from falling.

[0005] The technical solution of this utility model:

[0006] In one aspect of the utility model, there is provided an anti-falling structure for a ceiling bracket, the anti-falling structure comprising an anti-falling rope, the first end of the anti-falling rope being configured as a fixed end, the fixed end being fixed to the ceiling bracket or a carrier for hanging the ceiling bracket, the second end of the anti-falling rope being configured as a connecting end, the connecting end being detachably connected to a target object connected to the ceiling bracket via a connecting head, the connecting head comprising a connecting sleeve and / or a clamping piece. The anti-falling structure can effectively prevent the target object from falling.

[0007] Specifically, the connecting sleeve is fixed to the connecting end by means of a clamp, and the connecting sleeve is fixed to the target object by means of screws. The connecting end can be firmly connected to the target object by means of screws.

[0008] Specifically, the target object is a projection device, which has screw holes for height adjustment, and the connecting sleeve is fixed to the screw holes by means of screws. In this way, the screw holes on the projector can be directly used for installation, eliminating the process of drilling holes.

[0009] Specifically, the clamping piece is fixed on the connection end by means of a clamp. The clamping piece includes an I-shaped piece, and two end feet of the I-shaped piece close to the connection end extend out to form limiting pieces. In the initial state, the two limiting pieces are offset in opposite directions. Connecting the target object through the clamping piece enables the anti-falling structure to adapt to more scenarios and improves the application range of the anti-falling structure.

[0010] Specifically, the projection device has a grille. The clamping piece is inserted through the gap of the grille and then rotated. In the locked state, two end feet of the clamping piece away from the connection end penetrate to the bottom of the grille, and the two limiting pieces twist in the opposite direction so that the limiting pieces cooperate with the four end feet to lock on the grille. The projection device having a grille can cooperate with the clamping piece for fixation, and the reverse twisting of the limiting pieces cooperates with the end feet to fix the projection device more firmly.

[0011] Specifically, the connecting sleeve is fixed on the connection end by means of a clamp, and the clamping piece is connected to the connecting sleeve. The combined use of the clamping piece and the connecting sleeve can be applicable to different projectors according to the usage requirements. Even if different models of projectors are replaced, the existing anti-falling structure does not need to be disassembled.

[0012] On the other hand, the present utility model provides an anti-falling bracket, which includes an anti-falling structure containing all the above components and a ceiling bracket. The anti-falling bracket not only satisfies the function of adjusting the angle but also can effectively prevent the projection device from falling.

[0013] Specifically, the ceiling bracket includes a ceiling plate and a suspension rod connecting the ceiling plate. The fixed end of the anti-falling suspension rope is fixed inside the ceiling plate, and the connecting end of the anti-falling suspension rope is fixed on the target object connected to the ceiling bracket. In this way, the anti-falling structure and the ceiling bracket form an integral whole, and processes such as separately drilling holes for the fixed end of the anti-falling structure can be omitted.

[0014] Specifically, the suspension rod is a hollow structure, and the hollow structure communicates with the inside of the ceiling plate. A wiring hole is provided on the suspension rod, and the connecting end of the anti-falling suspension rope passes through the hollow structure and the wiring hole and extends out to be connected to the target object. The hollow structure provides a channel for the anti-falling suspension rope. The anti-falling suspension rope does not need to be connected to the projector from other positions, saving the length of the anti-falling suspension rope and making the force more reasonable.

[0015] Specifically, the anti-falling suspension rope is a steel wire rope. The steel wire rope has high strength, can bear a greater load, and improves the service life.

[0016] After adopting the above technical solution, compared with the prior art, the present utility model has the following beneficial effects:

[0017] The fixed end of the anti-falling suspension rope of the anti-falling structure is fixed on the ceiling bracket or the carrier hanging the ceiling bracket, and the connecting end of the anti-falling suspension rope is detachably connected to the projector connected to the ceiling bracket through a connector, which can effectively prevent the projection device from falling. And this anti-falling structure can be directly set on the ceiling bracket, so that the ceiling bracket and the anti-falling structure form an anti-falling bracket, which not only meets the function of adjusting the angle, but also can effectively prevent the projection device from falling.
