Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage lighting auxiliary technology, specifically to a swing limiting structure for stage lighting. Background Technology
[0002] Stage lighting fixtures are those that need to be suspended high in the air to project light onto the stage. Stage lighting fixtures can be used to create a specific atmosphere in places such as TV studios, theaters, performance halls, bars, and mobile performance venues. When fixing stage lighting fixtures, corresponding clamps are often needed to clamp them in place. After the clamps are clamped onto the stage lighting fixtures, the staff can adjust the angle or position of the stage lighting fixtures by swinging the clamps.
[0003] When using existing clamps for stage lighting fixtures to limit and fix them, bolts are generally used to tighten them. During rotation, the bolts have a certain degree of self-locking due to the helix angle of their threads. However, when using bolts to achieve the purpose of limiting, due to the safety considerations of stage lighting fixtures being located at a height, workers need to use appropriate auxiliary tools to tighten the bolts to ensure the stability of the limiting and fixing.
[0004] This means that when the angle of the clamps used to hold the stage lights needs to be adjusted, the staff needs to loosen the bolts before they can adjust the clamps, which makes the operation inconvenient and prevents the staff from easily adjusting the clamps used to hold the stage lights. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a swing limiting structure for stage lighting fixtures, which effectively solves the problem that the angle of the existing clamps used for clamping stage lighting fixtures is not easy to adjust.
[0006] The technical solution provided by this utility model is a swing limiting structure for stage lighting fixtures, including a fixed plate and a limiting swing assembly. The limiting swing assembly consists of multiple components and is evenly distributed on one side of the fixed plate. The swing assembly can drive the stage lighting fixtures on it to form different angles relative to the plane of the fixed plate that carries the limiting swing assembly.
[0007] The limiting swing assembly includes a support base, a bearing block, a limiting post, and a limiting groove. The support base is mounted on a fixed plate to provide rotational support for the bearing block. The bearing block is detachably connected to the stage lighting fixture for stage lighting fixture installation. The limiting groove is opened on the support base to accommodate the limiting post.
[0008] The limiting groove includes a limiting part and a connecting part. The connecting part is an arc shape whose center coincides with the rotation axis of the bearing block. The limiting part consists of two symmetrically arranged on both sides of the connecting part. The limiting part is a circle with a diameter greater than the width of the limiting part. The limiting post can be inserted into the connecting part or the limiting part and can move from one limiting part to the other limiting part via the connecting part.
[0009] Preferably, the limiting post includes a positioning part and a swinging part. The diameter of the positioning part is the same as the diameter of the limiting part and can be inserted into the limiting part for limiting the rotation limit position of the bearing block. The diameter of the swinging part is the same as the diameter of the connecting part and can be inserted into the connecting part and slide along the connecting part. The swinging part and the limiting part are connected by a funnel-shaped connecting surface.
[0010] Preferably, a limiting slot is provided on the positioning part, and a limiting plate that extends beyond the limiting slot is inserted into the limiting slot, and the limiting plate is in contact with the inner side wall of the bearing block.
[0011] Preferably, the support block has a limiting hole for accommodating the limiting post, and the positioning part is connected to the support block via a spring.
[0012] Preferably, the support base is further provided with an auxiliary groove located on the opposite side of the limiting groove, and the limiting post is inserted into the auxiliary groove to assist in guiding the limiting post.
[0013] Preferably, the support base and the bearing block are provided with rotating holes, and the support base is provided with a rotating shaft that is inserted into the bearing block and the rotating hole.
[0014] Preferably, the fixing plate has multiple waist-shaped fixing holes, and the fixing plate is fixed by bolts inserted into the fixing holes.
[0015] The beneficial effects of this utility model are as follows:
[0016] This utility model can limit and fix the carrier block at a suitable angle through the limiting part included in the limiting groove and the positioning part in the limiting column. In addition, a connecting part is provided between two adjacent limiting parts, and a swinging part that works with the connecting part is provided on one side of the positioning part. When the swinging part is inserted into the connecting part, the carrier block can rotate along the rotating shaft, thereby better driving the clamps set on the carrier block for clamping the stage lights to swing.
[0017] This utility model, through a funnel-shaped connecting surface that expands outward from the swinging part to the positioning part and a spring that is located between the positioning part and one side of the bearing block, allows the operator to simply press the limiting post into the bearing block and insert the swinging part into the connecting part to release the limiting post and swing the bearing block. When the limiting post is located in another positioning part, it can automatically insert into the positioning part under the action of the spring to achieve angular limiting of the bearing block.

Detailed Implementation
[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0024] Refer to the instruction manual appendix Figure 1-4 A swing limiting structure for stage lighting fixtures includes a fixed plate 1 and a limiting swing assembly. The limiting swing assembly consists of multiple components and is evenly distributed on one side of the fixed plate 1. The limiting swing assembly can drive the stage lighting fixtures on it to form different angles relative to the plane of the fixed plate 1 that supports the limiting swing assembly. The stage lighting fixtures are mounted on the limiting swing assembly and swing through the limiting swing assembly. When the stage lighting fixtures swing to the appropriate position, the limiting swing assembly can automatically limit and fix the stage lighting fixtures.
[0025] The limiting swing assembly includes a support base 2, a bearing block 3, a limiting post, and a limiting groove. The support base 2 is installed on the fixed plate 1 to provide rotational support for the bearing block 3. The bearing block 3 is detachably connected to the stage lighting fixture for stage lighting fixture installation. The limiting groove is opened on the support base 2 to accommodate the limiting post. The bearing block 3 has holes for inserting the clamping claws of the stage lighting fixture into the holes and can be limited by bolts and clamping claws of the stage lighting fixture.
[0026] The limiting groove includes a limiting part 4 and a connecting part 5. The connecting part 5 is an arc shape with its center coinciding with the rotation axis of the bearing block 3. The limiting part 4 consists of two symmetrically arranged on both sides of the connecting part 5. The limiting part 4 is a circle with a diameter greater than the width of the limiting part 4. The limiting post can be inserted into the connecting part 5 or the limiting part 4 and can move from one limiting part 4 to the other limiting part 4 via the connecting part 5. When the limiting post is inserted into the limiting part 4, it can fix the bearing block 3. When the limiting post is inserted into the connecting part 5, it can slide along the connecting part 5. The setting of the limiting part 4 and the connecting part 5 can better swing and limit the bearing block 3.
[0027] The limiting post includes a positioning part 6 and a swinging part 7. The diameter of the positioning part 6 is the same as that of the limiting part 4 and can be inserted into the limiting part 4 to limit the rotation limit position of the bearing block 3. The diameter of the swinging part 7 is the same as that of the connecting part 5 and can be inserted into the connecting part 5 and slide along the connecting part 5. The swinging part 7 and the limiting part 4 are connected by a trumpet-shaped connecting surface 8. The positioning part 6 and the limiting part 4 have the same diameter and can limit the bearing block 3 by inserting into the limiting part 4. The swinging part 7 and the connecting part 5 have the same diameter and can slide by contact between the swinging part 7 and the connecting part 5. The trumpet-shaped connecting surface 8 between the swinging part 7 and the limiting part 4 allows the connecting part 5 to move better toward the swinging part 7.
[0028] The positioning part 6 has a limiting slot 9, and a limiting plate 10 that extends beyond the limiting slot 9 is inserted into the limiting slot 9. The limiting plate 10 contacts the inner side wall of the bearing block 3. The limiting plate 10 inserted into the limiting slot 9 can prevent the limiting post from slipping.
[0029] The support block 3 has a limiting hole 11 for accommodating the limiting post. The positioning part 6 is connected to the support block 3 via a spring 12. Under the action of the spring 12, the support block 3 can swing to a suitable position, and then the positioning part 6 automatically inserts into the limiting hole 11.
[0030] The support base 2 is also provided with an auxiliary groove 13 located on the opposite side of the limiting groove. The limiting post is inserted into the auxiliary groove 13 to assist in guiding the limiting post. The end of the limiting post away from the positioning part 6 is inserted into the auxiliary groove 13 and guided by the auxiliary groove 13.
[0031] The support base 2 and the bearing block 3 are provided with rotating holes 14. The support base 2 is provided with a rotating shaft 15 that is inserted into the bearing block 3 and the rotating hole 14. The bearing block 3 can swing relative to the support base 2 through the rotating shaft 15 and the rotating hole 14.
[0032] The fixing plate 1 has multiple waist-shaped fixing holes 16. The fixing plate 1 is fixed by bolts inserted into the fixing holes 16. Under the action of the fixing holes 16, the fixing plate 1 can be fixed on a suitable plane by bolts.
[0033] It should be further explained that the limiting part 4 can be not just two, but multiple, and a connecting part 5 is provided between two adjacent limiting parts 4.
[0034] When this utility model is used, the support base 2 is installed on the fixed plate 1, and the bearing block 3 is inserted between two corresponding support bases 2. After the bearing block 3 is inserted, the support base 2 and the bearing block 3 are sequentially passed through the rotating shaft 15. Under the action of the rotating shaft 15, the bearing block 3 can rotate relative to the support base 2. After the bearing block 3 is installed, the worker inserts the limiting post into the limiting groove, and the limiting plate 10 and the limiting groove 9 limit the limiting post inserted into the limiting groove.
[0035] Meanwhile, the spring 12 is located between the swing part 7 of the limiting post and the bearing block 3. The positioning part 6 of the limiting post can be inserted into the limiting part 4 corresponding to the limiting groove at a suitable position through the spring 12.
[0036] After the spring 12 and the limiting plate 10 are installed, the staff inserts the clamping claws for clamping the stage lights into the holes opened on the bearing block 3 and limits the clamping claws for clamping the stage lights by bolts.
[0037] When the clamps used to hold the stage lights are fixed on the support block 3, the staff can move the limiting post to switch between the swing part 7 and the positioning part 6 on the limiting post, thereby fixing or swinging the support block 3 relative to the support base 2.
[0038] This utility model can limit and fix the bearing block 3 at a suitable angle through the limiting part 4 included in the limiting groove and the positioning part 6 in the limiting column. In addition, a connecting part 5 is provided between two adjacent limiting parts 4. At the same time, a swinging part 7 that works with the connecting part 5 is provided on one side of the positioning part 6. When the swinging part 7 is inserted into the connecting part 5, the bearing block 3 can rotate along the rotating shaft 15, thereby better driving the gripper set on the bearing block 3 for clamping the stage lighting to swing.
[0039] This utility model, through a funnel-shaped connecting surface 8 extending outward from the swinging part 7 to the positioning part 6 and a spring 12 disposed between the positioning part 6 and one side of the bearing block 3, allows the operator to simply press the limiting post into the bearing block 3 and insert the swinging part 7 into the connecting part 5 to release the limiting post and swing the bearing block 3. When the limiting post is located in another positioning part 6, it can automatically insert into the positioning part 6 under the action of the spring 12 to achieve angular limiting of the bearing block 3.
