Abstract
Description
Technical Field
[0001] This application relates to components of lighting devices, and more particularly to a claw-type lamp hook. Background Technology
[0002] In stage lighting and film and television equipment installation, eagle claw-type light hooks are often used as auxiliary accessories for hanging light fixtures. An eagle claw-type light hook generally consists of a hook body, clamping components, and a handle. In actual use, because eagle claw-type light hooks are typically used in stage and film shooting scenarios, they often require frequent installation and operation, and also need to be compatible with support rods of different diameters.
[0003] Typically, eagle-claw type lamp hooks clamp the support rod by controlling the relative position of the clamping component and the hook body through a handle. The handle needs to provide torque to the clamping component through a connecting part, thereby moving the clamping component to complete the clamping action. In the prior art, the handle and the clamping component are usually connected through multiple hinge points and connecting parts. The existing rod clamping device, which consists of a first clamping body, a second clamping body, a connecting rod, and multiple sets of hinges to form a locking mechanism, can achieve rod clamping. However, its structure includes multiple hinge points such as a first hinge, a second hinge, a third hinge, and a fourth hinge, and the relative position of the first and second clamping bodies is controlled by the connecting rod. Although the above method can effectively solve the problem of eagle-claw type lamp hooks hanging support rods of different sizes, its multi-hinged point structure design is relatively complex, resulting in high manufacturing costs.
[0004] Therefore, simplifying the mechanical structure of the eagle claw-type lamp hook is a technical problem that urgently needs to be solved. Utility Model Content

[0060] In order to solve the technical problem of high manufacturing cost of eagle claw type lamp hooks due to complex structure in the background technology.
[0061] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0062] See Figures 1 to 6 This embodiment provides an eagle claw type lamp hook, including: hook body 1, handle 2 and rotating elastic component 3; handle 2 is rotatably connected to hook body 1; rotating elastic component 3 is rotatably connected to hook body 1; rotating elastic component 3 includes a first rotating arm 31 and a second rotating arm 32; the first rotating arm 31 is connected to handle 2 and rotates with handle 2; the second rotating arm 32 and hook body 1 enclose an adjustable clamping space 4.
[0063] It should be explained in detail that: Hook 1 is the main load-bearing component, used to stabilize the suspended lamps and clamp the support rod. Hook 1 consists of two parts: a fixing clip 11 and a lamp holder 12. The fixing clip 11 and the lamp holder 12 are not separate parts, but rather two parts distinguished by specific functions. The fixing clip 11 is used to stabilize the support rod. The shape of the fixing clip 11 will vary depending on the support rod. For example, when the support rod is a circular rod, the fixing clip 11 is arc-shaped; when the support rod is a rectangular rod, the fixing clip 11 is square. The lamp holder 12 is provided with screw through holes for lamp holder screws to pass through, and the lamp holder screws are used to connect the lamps to be suspended. In addition, the hook body 1, as the main load-bearing component, has a certain thickness. A hollow part 13 is provided between the fixed clip 11 and the lamp base 12. The hollow part 13 provides space for the clamping support rod. The area of the hollow part 13 needs to be sufficient to accommodate the movement of operating components such as the handle 2 and the second rotating arm 32. The sides of the hollow part 13 are the sides of the hook body 1. Several through holes are provided on the sides for connecting with operating components such as the handle 2.
[0064] Handle 2 is the main operating component used to control the tightness of the clamping rod. The end of handle 2 near hook body 1 is hollowed out, which is used to accommodate connecting components or rotating elastic components 3, etc. Several pairs of through holes are provided on both sides of the hollowed-out portion 13, which are used to connect with components such as hook body 1. Specifically, a pair of second lugs 21 are provided at the end of handle 2 near hook body 1, and a pair of through holes are provided opposite to the second lugs 21. These through holes correspond to a pair of through holes on hook body 1. Handle 2 and hook body 1 are rotatably connected by a connector, which can be a hinge or a rivet. The connector passes through the corresponding through holes of handle 2 and hook body 1, realizing the rotatable connection between handle 2 and hook body 1.
[0065] The rotating elastic component 3 is used to transmit the torque of the handle 2 into the torque for clamping the support rod. The rotating elastic component 3 can be a spring or an elastic plastic; the specific type is not limited. The rotating elastic component 3 is rotatably connected to the hook body 1, and the method of rotatable connection varies depending on the type of rotating elastic component 3. The rotating elastic component 3 includes a first rotating arm 31, a second rotating arm 32, and an elastic element 33. The torque of the first rotating arm 31 is transmitted to the second rotating arm 32 through the elastic element 33. The first rotating arm 31 is connected to the handle 2 and rotates with the handle 2. The connection method is not limited; it can be abutment or fixed connection, as long as it ensures that the first rotating arm 31 can rotate with the handle 2. The second rotating arm 32 and the hook body 1 form an adjustable clamping space 4. Specifically, the second rotating arm 32 and the fixed clamp 11 of the hook body 1 form the clamping space 4. Since the fixed clamp 11 is not movable, when the first rotating arm 31 rotates with the rotation of the handle 2, the relative position of the second rotating arm 32 and the fixed clamp 11 changes, and the clamping space 4 they jointly form also changes accordingly.
[0066] It is worth noting that the rotating elastic component 3 has a restoring force, which can be in two directions. The first is that the restoring force drives the second rotating arm 32 to rotate toward the fixed clamping page 11, that is, to rotate toward the clamping direction. In the initial state, the clamping space 4 formed by the second rotating arm 32 and the fixed clamping page 11 is small. By applying pressure or tension to the handle 2, the handle 2 is rotated. At the same time, the handle 2 drives the first rotating arm 31 to rotate. After the first rotating arm 31 rotates, the elastic element 33 undergoes elastic deformation to store elastic potential energy. The elastic element 33 transfers the elastic potential energy to the second rotating arm 32, driving the second rotating arm 32 to rotate away from the fixed clamping page 11, thereby expanding the clamping space 4. In the second scenario, the resetting force drives the second rotating arm 32 to rotate away from the fixed clamping page 11, i.e., to rotate in the direction of release. In the initial state, the clamping space 4 formed by the second rotating arm 32 and the fixed clamping page is relatively large. By applying pressure or tension to the handle 2, the handle 2 is rotated. At the same time, the handle 2 rotates, causing the first rotating arm 31 to rotate. After the first rotating arm 31 rotates, the elastic element 33 undergoes elastic deformation to generate elastic potential energy. The elastic element 33 transfers the elastic potential energy to the second rotating arm 32, causing the second rotating arm 32 to rotate towards the fixed clamping page 11, thereby reducing the clamping space 4.
[0067] Preferably, the rotating elastic component 3 is a torsion spring, and the first rotating arm 31 is the first torsion arm, and the second rotating arm 32 is the second torsion arm. The torsion spring is rotatably connected to the hook body 1. Specifically, the spring body of the torsion spring is sleeved on the connecting part where the hook body 1 and the handle 2 are rotatably connected. The first torsion arm of the torsion spring abuts against the handle 2 and rotates with the rotation of the handle 2. The second torsion arm and the fixing clip 11 of the hook body 1 form a clamping rod space 4 for clamping the support rod. By applying pressure or tension to the handle 2, the handle 2 is rotated. The handle 2 drives the first torsion arm to rotate. When the first torsion arm is compressed, the elastic potential energy of the spring body increases. This elastic potential energy drives the second torsion arm to rotate, thereby increasing the clamping rod space 4 and realizing the adjustment of the clamping rod tightness.
[0068] Preferably, when the cross-sectional area of the support rod is large, the second rotating arm 32 may not be able to stably clamp the support rod. To solve this problem, the second rotating arm 32 can be set as an arc, with the center of the arc facing the opening direction of the hook body 1. The arc design makes the contact area between the second rotating arm 32 and the support rod larger and the force distribution more uniform, thereby increasing the stability during clamping. In addition, the arc design allows the second rotating arm 32 to more effectively wrap the support rod, improving the stability and reliability of the support rod. The fact that the center of the arc faces the opening direction of the hook body 1 is to enable the second rotating arm 32 and the fixed clamping page 11 to form a clamping space 4 for the support rod.
[0069] In actual operation, when the restoring force of the rotating elastic component 3 drives the second rotating arm 32 to move closer to the fixed clamping page 11 of the hook body 1, the opening of the clamping space 4 is at its minimum state without external force, making it impossible to fit a support rod with a larger diameter. At this time, the operator needs to press the handle 2 to drive the first rotating arm 31 to rotate. The first rotating arm 31 transfers elastic potential energy to the second rotating arm 32 through the elastic element 33, driving the second rotating arm 32 to rotate away from the fixed clamping page 11, so that the clamping space 4 gradually expands until the size is suitable for the support rod. Conversely, when the restoring force of the rotating elastic component 3 drives the second rotating arm 32 to rotate away from the fixed clamping page 11, the opening of the clamping space 4 is at its maximum state in the initial state, and support rods of different sizes can be directly fitted. During operation, pressing the handle 2 drives the first rotating arm 31 to rotate. The first rotating arm 31 transmits elastic potential energy to the second rotating arm 32 through the elastic element 33, causing the second rotating arm 32 to rotate in the direction of the fixed clamping page 11, so that the clamping space 4 gradually shrinks until it is tightly abutted against the outer periphery of the support rod, thereby achieving the clamping of support rods of different diameters.
[0070] The beneficial effects of this embodiment:
[0071] The eagle-claw type lamp hook of this embodiment includes a hook body, a handle, and a rotating elastic component. The handle and the rotating elastic component are rotatably connected to the hook body. The rotating elastic component includes a first rotating arm and a second rotating arm. The first rotating arm is connected to the handle and rotates with the handle. The second rotating arm and the hook body form an adjustable clamping space. When installing the lamp hook, pressing the handle rotates the first rotating arm. The first rotating arm, through its elastic potential energy, moves the second rotating arm away from the fixed clamping plate, increasing the clamping space to accommodate the support rod. After releasing the handle, the restoring force of the rotating elastic component causes the second rotating arm to clamp the support rod. The adjustable clamping space created by the rotating elastic component simplifies the mechanical structure compared to the multi-hinged structure of existing technologies, thereby reducing manufacturing costs. Example
[0072] In actual operation, when the support rod to be installed is large or smooth, the second rotating arm may be unable to effectively clamp the support rod due to limited contact area or insufficient friction, resulting in slippage or loosening.
[0073] The technical solution of this application is described in detail below with reference to the accompanying drawings.
[0074] See Figures 3 to 6To address this technical problem, this embodiment is an optimization based on Embodiment 1. The eagle claw-type lamp hook in this embodiment further includes a movable clip 5, which is rotatably connected to the hook body 1 and fixedly connected to the second rotating arm 32. The adjustable clamping space 4 formed by the second rotating arm 32 and the hook body 1 is replaced by the adjustable clamping space 4 formed by the movable clip 5 and the hook 1.
[0075] It should be noted that:
[0076] The movable clip 5 is used to clamp the support rod. It works in conjunction with the fixed clip 11 of the hook body 1 to wrap around the support rod, achieving the clamping purpose. Compared to the second rotating arm 32, the movable clip 5 has a larger contact area with the support rod, improving clamping stability and friction. The shape of the movable clip 5 depends on the shape of the support rod to be clamped. For example, it is arc-shaped when the support rod is round, and square when it is rectangular, to accommodate support rods with different cross-sectional shapes. The movable clip 5 may or may not pass through the cutout 13 of the hook body 1. When it passes through the cutout 13, its thickness is smaller than the fixed clip 11 to facilitate movement within the cutout 13. When it does not pass through the cutout 13, its thickness is greater than the fixed clip 11 to ensure structural strength and clamping force.
[0077] The movable clip 5 is rotatably connected to the hook body 1, allowing it to adapt to support rods of different sizes. Simultaneously, when clamped, it ensures that the movable clip 5 will not cause the lamp hook to loosen due to displacement. The rotatable connection method is not specifically limited and can be either hinged or pivotal. For example, the movable clip 5 has a hollowed-out portion 13 near the handle 2. A pair of circular lugs are provided on both sides of the hollowed-out portion 13 of the handle 2. These lugs can be located inside or outside the hollowed-out portion 13 of the hook body 1. Each lug has a through hole at its center, corresponding to the through holes in the handle 2 and the hook body 1. A hinge shaft passes through these through holes, and a rotating elastic component 3 is sleeved on the hinge shaft. When the handle 2 rotates, it drives the rotating elastic component 3, thereby driving the movable clip 5 to move.
[0078] The movable clip 5 is fixedly connected to the second rotating arm 32, ensuring that the second rotating arm 32 can move synchronously with the handle 2 to drive the movable clip 5 to adapt to support rods of different sizes. The fixed connection method is not limited and can be welding or gluing. The rigid connection achieves stable torque transmission, so that when the handle 2 rotates, it can drive the second rotating arm 32 through the rotating elastic component 3, thereby driving the movable clip 5 to adjust the size of the clamping space 4 and complete the clamping adaptation of support rods of different specifications.
[0079] Preferably, to prevent the lamp hook from slipping due to insufficient friction caused by the smooth surface of the support rod, the clamping surfaces of the fixed clip 11 and the movable clip 5 of the hook body 1 are provided with anti-slip protrusions 52. The anti-slip protrusions 52 increase the roughness of the contact surface, thereby improving the friction during clamping. The shape of the anti-slip protrusions 52 is not specifically limited; they can be elongated protrusions or regularly arranged hemispherical protrusions.
[0080] The adjustable clamping space 4 formed by the second rotating arm 32 and the hook 1 is replaced by the adjustable clamping space 4 formed by the movable clamp 5 and the hook 1. In this embodiment, the movable clamp 5 replaces the fixed clamp 11 of the second rotating arm 32 and the hook 1 to clamp the support rod. Since the contact area between the movable clamp 5 and the support rod is larger than the contact area between the second rotating arm 32 and the support rod, it can generate greater friction and resistance, thereby significantly improving the stability of the clamping state.
[0081] In actual operation, when no external force is applied, the restoring force of the rotating elastic component 3 drives the second rotating arm 32 to move towards the fixed clip 11 of the hook body 1, thereby causing the movable clip 5 to synchronously approach the fixed clip 11. At this time, the opening of the clamping rod space 4 is small and cannot fit the support rod with a larger diameter. When installing the lamp hook, the operator first presses the handle 2, which drives the first rotating arm 31 to rotate. The first rotating arm 31 transfers elastic potential energy to the second rotating arm 32, which drives the second rotating arm 32 to rotate the movable clip 5 away from the fixed clip 11, so that the opening of the clamping rod space 4 is widened enough to fit the support rod. Then, the support rod is placed in the clamping rod space 4, the handle 2 is released, and the restoring force of the rotating elastic component 3 pushes the second rotating arm 32 to bring the movable clip 5 closer to the fixed clip 11, thereby clamping and fixing the support rod.
[0082] The beneficial effects of this embodiment:
[0083] This embodiment of the eagle claw-type lamp hook features a movable clip, which is rotatably connected to the hook body and fixedly connected to the second rotating arm. The movable clip and the hook body enclose an adjustable clamping space. When installing a larger or smoother support rod, pressing the handle rotates the second rotating arm, carrying the movable clip. Because the contact area between the movable clip and the support rod is larger than that of the second rotating arm, it provides more friction and resistance, improving clamping stability and reliability. By replacing the second rotating arm with the movable clip to perform the clamping function, and utilizing its larger contact area, the slippage and loosening problems that easily occur in traditional structures when clamping large or smooth support rods are effectively solved. Example
[0084] In practical operation, relying solely on the rotational elastic component to provide torque may result in insufficient torque output or limited adjustment precision. This can lead to insufficient clamping force and easy loosening of the eagle-claw lamp hook when holding the support rod. Especially when dealing with large-diameter or high-load support rods, the deformation of the elastic component may not be able to stably maintain the preset size of the clamping space, affecting clamping stability. Therefore, addressing the issue of insufficient torque provided by the rotational elastic component affecting the stability of the eagle-claw lamp hook is a technical problem that urgently needs to be solved.
[0085] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0086] See Figures 3 to 6 To solve this technical problem, this embodiment is an optimization based on embodiment two. The eagle claw-type lamp hook in this embodiment is also provided with a live screw 6, a first rotating shaft 14, a second rotating shaft 7, and a limiting part 8. The handle 2 and the rotating elastic component 3 are both rotatably connected to the hook body 1 through the first rotating shaft 14. The head of the live screw 6 passes through the limiting part 8 and is rotatably connected to the handle 2 through the second rotating shaft 7. The axis of the first rotating shaft 14 is parallel to the axis of the second rotating shaft 7. The movable clip 5 is provided with a first lug 51 near the pressing end of the handle 2. The first lug 51 is connected to the live screw 6 through the limiting part 8. The live screw 6 is also provided with a wing nut 61 and a flat washer 62 at one end of the thread. The flat washer 62 is closer to the limiting part 8 than the wing nut 61. The wing nut 61 and the live screw 6 are threadedly connected. The thread of the live screw 6 extends to the position corresponding to the first lug 51. When the first lug 51 moves towards the handle 2, the clamping space 4 becomes smaller.
[0087] It should be noted that the union screw 6 is used for mechanical transmission and lamp hook clamping adjustment. It includes a head, a smooth screw and a threaded screw. The head is provided with a through hole that can be fitted onto the second rotating shaft 7. It is rotatably connected to the handle 2 through the second rotating shaft 7, so that the union screw 6 can rotate relative to the handle 2 to adapt to the first lug in different rotation positions. At the same time, the head passes through the limiting part 8 and the screw is in the limiting part 8 to ensure that the movable clamp 5 can be driven to move by adjusting the wing nut 61.
[0088] The movable clip 5 has a first lug 51 near the pressing end of the handle 2, which is used to receive the axial thrust of the wing nut 61 on the slip screw 6. Under the action of this thrust, the first lug 51 rotates towards the handle 2. When the first lug 51 rotates towards the handle 2, the clamping space 4 becomes smaller. Specifically, since the first lug 51 is part of the movable clip 5, its rotation direction is consistent, that is, it rotates clockwise or counterclockwise at the same time. The movable clip 5 is divided into a clamping part and the first lug 51 by the first rotating shaft 14. The movable clip 5 rotates around the first rotating shaft 14. When the first lug 51 rotates downward, the clamping part rotates upward. Therefore, in order to make the clamping space 4 smaller when the first lug 51 moves towards the handle 2, the first lug 51 is positioned above the handle 2, that is, the first lug 51 is located between the handle and the fixed clip on the side away from the clamping space. When the relative position of the handle 2 and the first lug 51 of the movable clip 5 changes, the snap screw 6 can rotate with the handle 2 without hindering the movement of the movable clip 5. The smooth screw and the threaded screw respectively play the roles of force transmission transition and connection adjustment components.
[0089] One threaded end of the union screw 6 is provided with a wing nut 61 and a flat washer 62. The wing nut 61 increases the torque by expanding the rotational contact surface, facilitating operation. The width or diameter of the flat washer 62 is greater than the distance between the first lugs 51 of the movable clip 5. When the wing nut 61 is screwed into the limiting part 8 along the axis of the union screw 6, it pushes the flat washer 62 to move towards the first lug 51. After the flat washer 62 moves to the position where it abuts against the first lug 51, it continues to screw the wing nut 61 in, thereby pushing the first lug 51 to rotate towards the handle, transmitting force to the clamping rod of the movable clip 5, and achieving further clamping. The flat washer 62 can be round or square, etc. The flat washer 62 is located between the wing nut 61 and the limiting part 8, ensuring that when the wing nut 61 moves, it can drive the flat washer 62 to act together on the first lug 51. Optionally, an anti-slip plate 63 can be provided between the wing nut 61 and the flat washer 62 to increase friction and prevent the wing nut 61 from loosening due to vibration during clamping. The wing nut 61 is threadedly connected to the union screw 6, and moves along the screw axis when rotating. The thread of the union screw 6 extends to the position corresponding to the first lug 51 of the movable clip 5, so as to effectively drive the movable clip 5 to move closer to the handle 2 when the wing nut 61 is rotated, thereby clamping the support rod.
[0090] The first rotating shaft 14 is used to achieve the rotational connection between the handle 2, the rotating elastic component 3, and the hook body 1. The second rotating shaft 7 is used to achieve the rotational connection between the union screw 6 and the handle 2. The axes of the first rotating shaft 14 and the second rotating shaft 7 are parallel to ensure that the handle 2, the rotating elastic component 3, the union screw 6, and the movable clip 5 all rotate in the same plane. Specifically, when the handle 2 rotates around the hook body 1 via the first rotating shaft 14, it drives the first rotating arm 31 of the rotating elastic component 3 to move synchronously. The second rotating arm 32 of the rotating elastic component 3 is connected to the movable clip 5, thereby driving the movable clip 5 to move. At the same time, the union screw 6 is connected to the handle 2 via the second rotating shaft 7 and rotates in the same plane with the handle 2. Its screw is connected to the first lug 51 of the movable clip 5 via the limiting part 8.
[0091] The limiting part 8 is used to connect the union screw 6 and the movable clip 5 and to restrict the movement trajectory of the union screw 6. On the one hand, it is necessary to connect the union screw 6 to the first lug 51 of the movable clip 5. On the other hand, it is necessary to limit the movement direction of the union screw 6. Since the union screw 6 is rotatably connected to the second rotating shaft 7, if the rotation range is not limited, the union screw 6 may rotate arbitrarily in the direction of the handle 2 and cannot provide pressure through axial movement. The structure of the limiting part 8 is not limited. For example, it can be a pin structure with a through hole or a cam structure. By cooperating with the union screw 6, it ensures that it moves in a preset direction and achieves connection with the movable clip 5.
[0092] Preferred, see Figure 3 To improve the connection stability between the live screw 6 and the movable clip 5, the limiting part 8 can be a hinge shaft. The live screw 6 is hinged to the first lug 51 through the hinge shaft. Specifically, the first lug 51 is a pair of circular lugs with a pair of through holes at their centers. The hinge shaft passes through the through holes and is fixed to the first lug 51. The hinge shaft has a through hole at its center for the live screw 6 to pass through, thereby realizing the hinged connection between the live screw 6 and the first lug 51 and ensuring that the two maintain a stable rotational linkage relationship during transmission.
[0093] Preferred, see Figure 4 The limiting part 8 includes a first limiting rod 81 and a second limiting rod 82. The first limiting rod 81, the second limiting rod 82, and the first lug 51 together form a limiting hollow part 83, and the movable screw 6 passes through the limiting hollow part 83. Specifically, the first lug 51 consists of two flat plates that are bent towards the handle and aligned parallel to each other. The gap between the two flat plates corresponds to the hollow part on the handle. The two flat plates are provided with two pairs of through holes spaced a certain distance apart along the outward extension direction. The first limiting rod 81 and the second limiting rod 82 pass through the first pair of through holes and the second pair of through holes, respectively, thereby forming the limiting hollow part 83 between the two rods. The movable screw 6 is connected to the movable clip 5 by being located in the limiting hollow part 83. The rotation range of the movable screw 6 is limited by the two limiting rods.
[0094] In actual operation, when the operating handle 2 clamps the support rod, the rotating elastic component 3 may not provide sufficient torque. At this time, by rotating the wing nut 61, it moves along the thread axis of the union screw 6 towards the limiting part 8. Since the wing nut 61 is threadedly connected to the union screw 6, its rotation pushes the flat washer 62 to move synchronously. After the flat washer 62 abuts against the first lug 51 of the movable clip 5, it converts the rotational force of the wing nut 61 into an axial thrust, thereby driving the first lug of the movable clip 5 to rotate towards the handle 2, which in turn drives the clamping rod to rotate towards the fixed clip, thereby increasing the clamping force on the support rod. When the handle 2 is rotated, the union screw 6 rotates synchronously with the handle 2, but the limiting part 8 restricts its rotation range, allowing it to rotate only within a certain range relative to the handle, thus ensuring that the wing nut 61 is always aligned with the first lug, and thus ensuring that the screwing in of the wing nut 61 can apply pressure to the first lug.
[0095] The beneficial effects of this embodiment:
[0096] This embodiment of the eagle claw-type lamp hook incorporates a union screw, a first rotating shaft, a second rotating shaft, and a limiting part. The handle and the rotating elastic component are rotatably connected to the hook body via the first rotating shaft. Simultaneously, the head of the union screw passes through the limiting part and connects to the handle via the second rotating shaft. The axes of the first and second rotating shafts are parallel to ensure coordinated movement of all components within the same plane. The movable clip has a first lug near the handle's pressing end, and when the first lug moves towards the handle, the clamping space decreases. The first lug is connected to the union screw via the limiting part. Furthermore, the union screw has a wing nut and a flat washer at one threaded end, with the flat washer closer to the limiting part than the wing nut. The wing nut is threadedly connected to the union screw, and the thread of the union screw extends to a position corresponding to the first lug, thus forming a complete mechanical transmission and clamping adjustment structure. When the operator rotates the wing nut, because it is threadedly connected to the union screw, it moves along the thread axis towards the limiting part, pushing the flat washer to move synchronously. After the flat washer abuts against the first lug of the movable clip, it converts the rotational force of the wing nut into axial thrust, pushing the first lug towards the handle. After the first lug moves towards the handle, the clamping space further decreases, thereby enhancing the clamping force. This embodiment solves the problem of insufficient torque provided by the rotating elastic component affecting the stability of the eagle claw-type lamp hook by adding a live screw to increase pressure on the movable clip. Example
[0097] In practical operation, the claw-type lamp hook not only needs to adapt to different support rods, but also, after clamping support rods of different sizes, if the rotating elastic component cannot independently clamp the support rod, the lamp hook needs to be fixed. If the fixing method is complex or lacks stability, it may lead to reduced lamp installation efficiency, cumbersome operation, or even safety hazards such as the support rod loosening and the lamp falling due to accidental unlocking. Therefore, how to simplify the fixing structure of the claw-type lamp hook is an urgent technical problem to be solved.
[0098] The embodiments of this application are described in detail below with reference to the accompanying drawings.
[0099] See Figure 5 To solve this technical problem, the eagle claw lamp hook of this embodiment is an improvement on the second embodiment. In this embodiment, the handle 2 of the eagle claw lamp hook has an engaging protrusion 22 on the side near the hook body 1 in the rotation direction, and the movable clip 5 has an engaging groove 53 on the side near the handle 2 in the rotation direction. The engaging protrusion 22 and the engaging groove 53 are adapted to each other.
[0100] It should be noted that the engaging protrusion 22 of the handle 2 is located on the side of the handle 2 closest to the hook body 1 in the rotation direction. When the movable clip 5 clamps the support rod under the action of the rotating elastic component 3, the engaging protrusion 22 rotates with the handle 2 towards the hook body 1, aligning and engaging with the engaging groove 53 of the movable clip 5. The mechanical engagement generates resistance, restricting the directional movement of the handle 2, thereby locking the position of the movable clip 5. The specific shapes of the engaging protrusion 22 and the engaging groove 53 are not limited, but their shapes need to be compatible. The shape of the engaging protrusion 22 can be toothed or a protruding structure, while the engaging groove 53 can be a toothed groove or a recess.
[0101] The beneficial effects of this embodiment:
[0102] This embodiment features an engaging protrusion on the side of the handle near the hook body in the rotation direction, and a matching engaging groove on the side of the movable clip near the handle in the rotation direction. During operation, when the movable clip clamps the support rod under the action of the rotating elastic component, the handle rotation causes the engaging protrusion to align and engage with the engaging groove. This mechanical engagement creates resistance, restricting the handle from rotating in the opposite direction, thus locking the movable clip's position. No additional complex fixing components are needed; locking is achieved through the engagement between the handle and the movable clip's own structure, solving the technical problem of simplifying the eagle-claw type lamp hook fixing structure. Example
[0103] In practice, the lighting fixtures suspended by eagle-claw style light hooks are mostly multi-functional fixtures such as stage lights and motion lights. These fixtures are usually quite heavy and need to rotate during operation. If the light hook lacks a locking mechanism, it may accidentally loosen under external influences, causing the light fixture to fall and resulting in serious consequences. Therefore, the vulnerability of light hooks to accidental detachment due to external factors is a technical problem that urgently needs to be solved.
[0104] The technical solution of this application is described in detail below with reference to the accompanying drawings.
[0105] See 1 to Figure 6 To address this technical problem, optimizations were made based on Embodiment 1. The eagle-claw type lamp hook of this embodiment further includes a locking component 9, which comprises a check pawl 91, a ratchet 92, and a reset component 93. The check pawl 91 is rotatably connected to the handle 2, and its engaging end is adapted to the ratchet 92. The ratchet 92 is connected to the hook body 1, and the protruding direction of the ratchet teeth gradually tends towards the side where the handle 2 is located in the initial state, where the clamping force is at its maximum. The reset component 93 connects the check pawl 91 and the handle 2, and is used to drive the engaging end to turn towards the ratchet 92.
[0106] The locking component 9 is used to lock the handle 2 in a rotational position corresponding to the required clamping degree, and includes a check pawl 91, a ratchet 92, and a reset component 93. Specifically, the check pawl 91 serves as the control component for unlocking and locking. It is rotatably connected to the handle 2 and rotates with the handle 2. Unlocking and locking are achieved by controlling its rotation. The shape of the check pawl 91 is not specifically limited; it can be a rectangular plate or a curved pawl. The ratchet 92 provides multiple support positions for the check pawl 91 with different circumferential distributions to provide stable support for the meshing end of the check pawl 91 as it rotates to different positions with the handle 2. Therefore, the protrusion direction of its ratchet teeth is designed to gradually tilt towards the side where the handle 2 is located in the initial state. That is, the closer the ratchet teeth are to the side where the handle 2 is located in the initial state, the greater the angle of inclination of their protrusion direction towards that side. This provides a support force to the meshing end that is opposite to the rotational force of the reset member 93. In this way, when the check pawl 91 is not under pressure, it is balanced by the combined action of the reset force of the reset member 93 and the support force of the ratchet teeth, and enters a stable static state, thereby locking the handle 2 connected to it at the position of the required rotation range. As for the reset component 93, its structure and material are not specifically limited. It can provide the power for the steering ratchet at the meshing end. It can be a compression spring or a shape memory material.
[0107] Furthermore, the check pawl 91 is rotatably connected to the handle 2. The specific connecting component is not limited; it can be a rolling bearing or a hinge connection. This rotatable connection allows the check pawl 91 to move with the handle 2 while also rotating on the handle 2 based on the connecting component. The meshing end of the check pawl 91 is adapted to the ratchet 92. The reset force of the reset component 93, combined with the support force provided by the ratchet teeth when the check pawl 91 and ratchet 92 are stably engaged, locks the check pawl 91, thereby locking the handle 2. Specifically, the shape of the check pawl 91 needs to match the limiting groove formed by the ratchet teeth of the ratchet 92. For example, if the meshing end of the check pawl 91 has a 75° convex angle, the inclination angle of the limiting groove formed by the force-bearing tooth surface and the return tooth surface of the ratchet teeth of the ratchet 92 should also be 75°. The ratchet 92 is connected to the hook body 1. The connection method is not specifically limited. It can be a fixed connection or a movable connection. When the adjustable range of the clamping degree of the hook body 1 is fixed, a fixed connection is used to increase stability. When the adjustable range of the clamping degree of the hook body 1 varies greatly, a movable connection is used to allow the ratchet 92 to engage with the check pawl 91 within a larger range, so that the position of the ratchet 92 can be adjusted to adapt to the changing adjustable range. The specific connection method depends on the requirements.
[0108] Furthermore, the protrusions of the ratchet teeth in the ratchet 92 gradually tend towards the side where the handle 2 is located in the initial state. Specifically, multiple ratchet teeth are continuously arranged on the ratchet 92. The number of ratchet teeth is not specifically limited and depends on the range of the lamp hook clamping. Among them, the side of the ratchet tooth that abuts against the check pawl 91 is the force-bearing tooth surface, which has a larger slope. The side of the ratchet tooth that supports the check pawl 91 is the return tooth surface, which has a smaller slope. Generally, in order to keep the check pawl 91 and the ratchet 92 compatible, in multiple sets of two adjacent ratchet teeth, the shape of the limiting groove formed by the force-bearing tooth surface of the current ratchet tooth and the return tooth surface of the previous ratchet tooth is consistent, and the angle formed by the force-bearing tooth surface and the return tooth surface is an acute angle. Therefore, the protrusions formed by the return tooth surface of the current ratchet tooth and the force-bearing tooth surface of the next ratchet tooth gradually tend towards the handle 2, that is, the opening of the limiting groove tends towards the side where the handle 2 is located in the initial state. This ensures that when the lamp hook clamps the support rod, the ratchet and the check pawl 91 engage stably, effectively preventing the handle 2 from rotating in the loosening direction. Considering that the check pawl 91 and the ratchet need to generate sufficient resistance to prevent the lamp hook from accidentally loosening, both must be made of rigid materials rather than elastic materials.
[0109] The reset element 93 connects the check pawl 91 to the handle 2 or hook 1, and is used to drive the engaging end to turn towards the ratchet 92. Specifically, depending on the type of reset element 93, the connection method between the reset element 93 and the check pawl 91 and the handle 2 or hook 1 is different, and the way it drives the engaging end to turn towards the ratchet 92 is different. For example, when the reset element 93 is a compression spring, one end of the spring is fixedly connected to the check pawl 91, and the other end is fixedly connected to the handle 2 or hook 1. The spring undergoes elastic deformation when there is external pressure, and when there is no external pressure, the compression spring generates elastic force to drive the engaging end to turn towards the ratchet 92. Preferably, the reset element 93 is a torsion spring. The torsion spring has a simple structure, occupies less space, and has a lower cost. The torsion spring includes two torsion arms and a spring body. The spring body can be sleeved at the connection between the handle 2 and the check pawl 91. One end of the torsion arm abuts against the check pawl 91, and the other end of the torsion arm abuts against the handle 2 or hook 1. When the check pawl 91 needs to be released, the applied pressure causes the torsion spring to deform elastically. The pressure drives the check pawl 91 to disengage from the ratchet 92, at which point the handle 2 can rotate freely. When the check pawl 91 is released after clamping the support rod, the restoring torque of the torsion spring will automatically reset it, causing it to re-engage with the ratchet 92, thus achieving a stable lock.
[0110] In actual operation, when the operator needs to install the lamp hook, the operator first needs to press the anti-return pawl 91 in the locking component 9 to disengage the anti-return pawl 91 from the ratchet 92, releasing the locked state and allowing the handle 2 to return to a rotatable state. Then, while keeping the thumb pressing the anti-return pawl 91, the operator rotates the handle 2 to move the movable clamp 5 in the hook body 1 towards the support rod until the hook body 1 and the support rod form a stable clamp. At this time, the operator releases the finger pressing the locking component 9, and the restoring force generated by the reset component 93 drives the anti-return pawl 91 to turn towards the ratchet 92, so that the two engage. Since the ratchet teeth of the ratchet 92 are inclined towards the handle 2, after the anti-return pawl 91 engages with the ratchet 92, the force-bearing tooth surface of the ratchet teeth of the ratchet 92 causes the anti-return pawl 91 to move in the opposite direction, and through the connection between the handle 2 and the anti-return pawl 91, the entire eagle claw lamp hook remains locked. When the operator needs to disassemble the lamp hook, the operator first needs to press the anti-return pawl 91 in the locking component 9 to disengage the anti-return pawl 91 from the ratchet 92, release the unlocked state, and allow the handle 2 to return to the rotatable state; then, while keeping the thumb pressing the anti-return pawl 91, the operator rotates the handle 2 to move the movable clip 5 of the hook body 1 away from the fixed clip 11, release the support rod, and complete the disassembly of the lamp hook.
[0111] The beneficial effects of this embodiment:
[0112] This embodiment incorporates a locking component in the eagle-claw type lamp hook. This locking component includes a check pawl, a ratchet, and a reset element. The check pawl is rotatably connected to the handle, and its engaging end is adapted to the ratchet. The ratchet is connected to the hook body, and the protruding direction of the ratchet teeth gradually tilts towards the handle side in the initial state, where the clamping force is at its maximum. The reset element connects the check pawl and the handle, driving the engaging end towards the ratchet. During operation, pressing the check pawl overcomes the resistance of the reset element, disengaging it from the ratchet, allowing the handle to rotate freely to adjust the clamping space. After releasing, the reset element drives the check pawl to reset, causing the engaging end to engage with the ratchet teeth. Utilizing the unidirectional abutment structure formed by the inclined design of the ratchet teeth, when the lamp is affected by external factors, the ratchet teeth convert the reverse impact force into pressure, working together with the reset element to prevent the handle from loosening, thus locking the clamping state and solving the technical problem of the lamp hook accidentally falling off due to external factors.
[0113] Alternatively, to solve this technical problem, another possibility exists: optimization based on Embodiment 1. The eagle claw-type lamp hook of this embodiment also includes a locking component 9, which includes a check pawl 91, a ratchet 92, and a reset component 93. The check pawl 91 is rotatably connected to the hook body 1, and its engaging end is adapted to the ratchet 92. The handle 2 has a second lug 21 at one end near the first rotating shaft 14. The ratchet 92 is connected to the second lug 21, and the protrusion of the ratchet teeth gradually tends towards the side where the check pawl 91 is located. The reset component 93 connects the check pawl 91 and the hook body 1, and is used to drive the engaging end to turn towards the ratchet 92.
[0114] It should be noted that:
[0115] The structure of the locking component 9 is the same as that of the previous embodiment. It is worth noting that the check pawl 91 is rotatably connected to the hook body 1. The specific connecting component is not limited; it can be a rolling bearing or a hinge shaft. The rotatable connection controls the handle 2 to be in the unlocked or locked state. The engaging end of the check pawl 91 is adapted to the ratchet 92. The reset force of the reset component 93, combined with the support force provided by the ratchet teeth when the check pawl 91 and ratchet 92 are stably engaged, locks the check pawl 91, thereby locking the handle 2. Specifically, the shape of the check pawl 91 needs to match the limiting groove formed by the ratchet teeth of the ratchet 92. For example, the engaging end of the check pawl 91 has a 75° convex angle, and the inclination angle of the limiting groove formed by the force-bearing tooth surface and the return tooth surface of the ratchet teeth of the ratchet 92 should also be 75°.
[0116] The handle 2 has a second lug 21 at the end near the first pivot 14, which connects to the hook body 1 and provides a larger contact area for the ratchet 92. The ratchet 92 is connected to the second lug 21. When the check pawl 91 engages with the ratchet 92, the ratchet 92 fixes the handle 2 through the second lug 21. The protrusions of the ratchet teeth are inclined towards the side where the check pawl 91 is located. The ratchet 92 has multiple ratchet teeth, the specific number of which depends on the requirements. The side that abuts against the check pawl 91 is a force-bearing tooth surface with a larger slope, and the side that supports the check pawl 91 is a return tooth surface with a smaller slope. To ensure that the check pawl 91 and the ratchet 92 are compatible, in multiple sets of adjacent ratchet teeth, the force-bearing tooth surface of the current ratchet tooth and the return tooth surface of the previous ratchet tooth form a limiting groove with the same shape.
[0117] The reset element 93 is connected to the check pawl 91 or the hook 1 to drive the meshing end to turn towards the ratchet 92. Specifically, depending on the type of the reset element 93, the connection method between the reset element 93 and the check pawl 91 and the hook 1 is different, and the way it drives the meshing end to turn towards the ratchet 92 is different. For example, when the reset element 93 is a compression spring, one end of the spring is fixedly connected to the check pawl 91, and the other end is fixedly connected to the hook 1. The spring undergoes elastic deformation when there is external pressure. When there is no external pressure, the compression spring generates elastic force to drive the meshing end to turn towards the ratchet 92.
[0118] In operation, when the operator needs to install the lamp hook, first press the anti-return pawl 91 of the locking component 9 to disengage it from the ratchet 92 and release the lock, allowing the handle 2 to resume its rotatable function. Then, while maintaining pressure on the anti-return pawl 91, rotate the handle 2 to move the movable clamp 5 of the hook body 1 towards the support rod until the hook body 1 and the support rod form a stable clamp. At this point, release the finger pressing the locking component 9; the restoring force generated by the reset component 93 drives the anti-return pawl 91 to turn towards the ratchet 92 and engage with it. Because the ratchet teeth of the ratchet 92 are inclined towards the anti-return pawl 91, the force-bearing tooth surface of the ratchet teeth after engagement prevents the anti-return pawl 91 from moving in the opposite direction. Through the connection between the ratchet 92 and the handle 2, the entire eagle claw lamp hook remains locked.
[0119] Beneficial effects of this embodiment
[0120] This embodiment adds a locking component to the eagle claw-type lamp hook. This locking component consists of a check pawl, a ratchet, and a reset member. The check pawl is rotatably connected to the hook body, and its engaging end is adapted to the ratchet. A second lug is provided at the end of the handle near the first rotating shaft; this second lug is connected to the ratchet, and the ratchet teeth protrude in an angle towards the side where the check pawl is located. The reset member connects the check pawl and the hook body and is used to drive the engaging end towards the ratchet. During operation, pressing the check pawl overcomes the resistance of the reset member, separating it from the ratchet, allowing the handle to rotate freely to adjust the clamping space. Releasing the reset member drives the check pawl to reset, causing its engaging end to engage with the ratchet. During operation, press the check pawl to overcome the resistance of the reset component and disengage it from the ratchet, allowing the handle to rotate freely to adjust the clamping space. After releasing, the reset component drives the check pawl to reset, causing its meshing end to engage with the ratchet teeth. Utilizing the unidirectional abutment structure formed by the inclined design of the ratchet teeth, when the lamp is affected by external factors, the ratchet teeth convert the reverse impact force into pressure, which, together with the reset component, prevents the handle from being released, thereby locking the clamping state and solving the technical problem of the lamp hook accidentally falling off due to external factors.
