Technical Field

[0001] The utility model relates to the field of lamp fixing tools, and particularly relates to a lamp hook. Background Art

[0002] Stage lamps are required in places such as television studios, theaters, concert halls, bars, and mobile performance venues to render the lighting environment. Since stage lamps need to be frequently adjusted according to the performance content, stage lamps are generally installed and fixed in a detachable manner, and the lamps are hung on suspension rods or trusses through lamp hooks. The patent document with the publication number CN 216744228 U discloses a universal lamp hook and a folding lamp hook applying the same. This lamp hook locks the movable hook and the mounting seat through a locking screw rod and a locking screw. Each installation and disassembly requires rotating the locking screw, and the overall disassembly and assembly efficiency is relatively low. Content of the Utility Model

[0003] The utility model aims at the above problems and overcomes at least one deficiency, and provides a lamp hook.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A lamp hook, comprising: a first clamping member, a second clamping member, a quick-release handle, a connecting member, and an adjusting bolt;

[0006] The first end of the first clamping member is rotatably installed on the first end of the second clamping member, and the second end of the first clamping member has an anti-disengagement portion;

[0007] The quick-release handle is rotatably installed on the second end of the second clamping member, and the quick-release handle has a strip-shaped hole;

[0008] One end of the connecting member has an adjusting portion, and the other end has a locking portion. The adjusting portion is located in the strip-shaped hole. The connecting member can move and rotate on the strip-shaped hole, and the locking portion is used to cooperate with the anti-disengagement portion;

[0009] One end of the adjusting bolt passes through the side wall of the strip-shaped hole and is in threaded cooperation with the adjusting portion. By rotating the adjusting bolt, the position of the adjusting portion in the strip-shaped hole can be adjusted;

[0010] The quick-release handle has a locking working position and an unlocking working position. When the quick-release handle is in the locking working position, the quick-release handle drives the adjusting portion to move towards the side away from the anti-disengagement portion, so that the connecting member pulls the second end of the first clamping member towards the second end of the second clamping member. When the quick-release handle is in the unlocking working position, the quick-release handle drives the adjusting portion to move towards the side close to the anti-disengagement portion, and the locking portion of the connecting member can be disengaged from the anti-disengagement portion.

[0011] When the lamp hook of the present application is installed, the inner side walls of the first clamping member and the second clamping member are attached to the suspension rod or truss, so that the second ends of the first clamping member and the second clamping member are close to each other. Rotate the quick-release handle towards the side close to the first clamping member (rotate upwards), and then place the locking portion of the connecting member on the anti-disengagement portion. Rotate the quick-release handle so that the quick-release handle rotates away from the first clamping member (rotate downwards). At this time, the connecting member pulls the second end of the first clamping member towards the second end of the second clamping member, and the lamp hook can be reliably fixed on the suspension rod or truss. When the lamp hook needs to be disassembled, rotate the quick-release handle towards the side close to the first clamping member (rotate upwards). At this time, the quick-release handle drives the adjusting portion to move towards the side close to the anti-disengagement portion, and the locking portion of the connecting member can be disengaged from the anti-disengagement portion. The first clamping member and the second clamping member can rotate relative to each other and be removed from the suspension rod or truss.

[0012] In addition, the present application is also provided with an adjusting structure, which can adapt to suspension rods or trusses of different sizes. Specifically, when the adjusting bolt is rotated to make the adjusting portion of the connecting member away from the second end of the first clamping member, the lamp hook can adapt to a suspension rod or truss of a smaller size at this time. When the adjusting bolt is rotated to make the adjusting portion of the connecting member close to the second end of the first clamping member, the lamp hook can adapt to a suspension rod or truss of a larger size at this time.

[0013] The size of the suspension rod or truss referred to in the present application refers to the radial size, such as the diameter. That is, the present application can achieve quick installation and disassembly operations by rotating the quick-release handle, and can adjust the position of the connecting member in the strip-shaped hole by rotating the adjusting bolt, so as to adapt to suspension rods or trusses of different sizes.

[0014] In one embodiment of the present invention, an anti-disengagement groove is formed on the side of the anti-disengagement portion facing away from the second clamping member, and the adjusting portion is used to be embedded in the anti-disengagement groove.

[0015] In one embodiment of the present invention, the connecting line between the rotation axis of the quick-release handle and the rotation axis of the first end of the second clamping member is line A. When the quick-release handle is in the locking working position, the connecting line between the force application points at both ends of the connecting member is line B. Line B intersects with line A, and at this time the lamp hook is in a self-locking state.

[0016] That is, the lamp hook forms self-locking after being clamped and cannot be disengaged by itself.

[0017] In one embodiment of the present invention, the anti-disengagement portion is an arc-shaped structure.

[0018] In one embodiment of the present invention, the connecting member further includes two connecting plates, and the connecting plates are used to connect the adjusting portion and the locking portion. The adjusting portion, the locking portion and the two connecting plates form a rectangular frame structure. The two connecting plates are respectively located on both sides of the second clamping member, and both ends of the adjusting portion are rotationally matched with the two connecting plates.

[0019] The connecting piece has a rectangular frame structure and can be reliably installed on the quick-release handle. The force-bearing condition of the adjusting part is uniform, and the locking part can also cooperate more reliably with the anti-disengagement part.

[0020] In one embodiment of the present utility model, the locking part is cylindrical; both ends of the locking part are rotatably fitted with two connecting plates respectively.

[0021] The locking part is cylindrical and can rotate relative to the two connecting plates. Such a setting facilitates the more reliable embedding of the locking part into the anti-disengagement groove and makes the operation more smooth.

[0022] In actual use, the adjusting part can be cylindrical, and the cross-section of the adjusting part can also be rectangular.

[0023] In one embodiment of the present utility model, the adjusting part is provided with a threaded hole, the side wall of the strip-shaped hole away from the rotation axis of the quick-release handle is provided with a through hole, and the screw part of the adjusting bolt passes through the through hole and is connected to the threaded hole.

[0040] The following will describe the present utility model in detail with reference to the accompanying drawings.

[0041] As Figures 1 to 5 shown, a lamp hook includes: a first clamping member 1, a second clamping member 2, a quick-release handle 3, a connecting member 4, and an adjusting bolt 5;

[0042] The first end 1a of the first clamping member is rotatably mounted on the first end 2a of the second clamping member, and the second end 1b of the first clamping member has an anti-disengagement portion 11;

[0043] The quick-release handle 3 is rotatably mounted on the second end 2b of the second clamping member, and the quick-release handle 3 has a strip-shaped hole 311;

[0044] One end of the connecting member 4 has an adjusting portion 41, and the other end has a locking portion 42. The adjusting portion 41 is located in the strip-shaped hole 311. The connecting member 4 can move and rotate on the strip-shaped hole 311, and the locking portion 42 is used to cooperate with the anti-disengagement portion 11;

[0045] One end of the adjusting bolt 5 passes through the side wall of the strip-shaped hole 311 and is in threaded cooperation with the adjusting portion 41. By rotating the adjusting bolt 5, the position of the adjusting portion 41 in the strip-shaped hole 311 can be adjusted;

[0046] The quick-release handle 3 has a locking working position and an unlocking working position. When the quick-release handle 3 is in the locking working position, the quick-release handle 3 drives the adjusting portion 41 to move toward the side away from the anti-disengagement portion 11, so that the connecting member 4 pulls the second end 1b of the first clamping member toward the second end 2b of the second clamping member. When the quick-release handle 3 is in the unlocking working position, the quick-release handle 3 drives the adjusting portion 41 to move toward the side close to the anti-disengagement portion 11, and the locking portion 42 of the connecting member 4 can be disengaged from the anti-disengagement portion 11.

[0047] When installing the lamp hook of the present application, the inner side walls of the first clamping member 1 and the second clamping member 2 are attached to the suspension rod or truss, so that the second end 1b of the first clamping member and the second end 2b of the second clamping member are close to each other. The quick-release handle 3 is rotated toward the side close to the first clamping member 1 (rotated upward), and then the locking portion 42 of the connecting member 4 is placed on the anti-disengagement portion 11. The quick-release handle 3 is rotated so that the quick-release handle 3 is rotated toward the side away from the first clamping member 1 (rotated downward). At this time, the connecting member 4 pulls the second end 1b of the first clamping member toward the second end 2b of the second clamping member, and the lamp hook can be reliably fixed on the suspension rod or truss; when the lamp hook needs to be disassembled, the quick-release handle 3 is rotated toward the side close to the first clamping member 1 (rotated upward). At this time, the quick-release handle 3 drives the adjusting portion 41 to move toward the side close to the anti-disengagement portion 11, and the locking portion 42 of the connecting member 4 can be disengaged from the anti-disengagement portion 11. The first clamping member 1 and the second clamping member 2 can rotate relative to each other and be removed from the suspension rod or truss.

[0048] In addition, the present application is also provided with an adjusting structure, which can adapt to boom rods or trusses of different sizes. Specifically, when the adjusting bolt 5 is rotated to move the adjusting portion 41 of the connecting member 4 away from the second end 1b of the first clamping member, the lamp hook can adapt to a boom rod or truss of a smaller size at this time. When the adjusting bolt 5 is rotated to move the adjusting portion 41 of the connecting member 4 closer to the second end 1b of the first clamping member, the lamp hook can adapt to a boom rod or truss of a larger size at this time.

[0049] The size of the boom rod or truss referred to in the present application refers to the radial dimension, such as the diameter. That is, the present application can achieve rapid installation and disassembly operations by rotating the quick-release handle 3, and the position of the connecting member 4 in the strip-shaped hole 311 can be adjusted by rotating the adjusting bolt 5, so as to adapt to boom rods or trusses of different sizes.

[0051] As Figure 4 shown, in the cross-sectional view state, the connecting line of the rotation axes of the quick-release handle 5 and the first end 2a of the second clamping member is line A. When the quick-release handle is in the locked working position, the connecting line of the force application points at both ends of the connecting member 4 is line B. Line B intersects line A, and at this time the lamp hook is in a self-locking state, that is, the lamp hook forms self-locking after clamping and cannot be disengaged by itself.

[0052] As Figure 2 and Figure 5 shown, in this embodiment, the connecting member 4 further includes two connecting plates 43. The connecting plates 43 are used to connect the adjusting portion 41 and the locking portion 42. The adjusting portion 41, the locking portion 42 and the two connecting plates 43 form a rectangular frame structure. The two connecting plates 43 are respectively located on both sides of the second clamping member 2, and both ends of the adjusting portion 41 are rotationally matched with the two connecting plates 43.

[0053] The connecting member 4 having a rectangular frame structure can be reliably installed on the quick-release handle 3, the force application condition of the adjusting portion 41 is uniform, and the locking portion 42 can also be more reliably matched with the anti-detachment portion 11.

[0056] In actual use, the adjusting part 41 can be cylindrical, and the cross-section of the adjusting part 41 can also be rectangular.

[0057] As Figure 2 , Figure 4 and Figure 5 shown, in this embodiment, the adjusting part 41 has a threaded hole 411, and the side wall of the strip-shaped hole 311 away from the rotation axis of the quick-release handle 3 has a through hole 3111. The screw part 51 of the adjusting bolt 5 passes through the through hole 3111 and is connected to the threaded hole 411.

[0058] As Figures 1 to 5 shown, in this embodiment, the quick-release handle 3 has a mounting part 31 and a handle part 32 connected in sequence. One end of the mounting part 31 away from the handle part 32 is rotatably mounted on the second end 2b of the second clamping member. The strip-shaped hole 311 is located in the mounting part 31 and between the rotation axis of the mounting part 31 and the handle part 32.

[0059] As Figure 2 and Figure 5 shown, in this embodiment, the second end 2b of the second clamping member has a mounting head 21. The middle part of one end of the mounting part 31 away from the handle part 32 has a notch 312. The mounting head 21 is embedded in the notch 312 and is rotatably connected to the mounting part 31 through a rotating shaft.

[0060] As Figure 1 shown, in this embodiment, the inner side walls of the first clamping member 1 and the second clamping member 2 are arc-shaped.

[0061] As Figure 1 shown, in this embodiment, a lamp mounting member 6 is mounted on the first clamping member 1 or the second clamping member 2. In actual use, the lamp mounting member 6 can be a bolt.

[0062] The above are only the preferred embodiments of the present invention, and thus do not limit the patent protection scope of the present invention.
