Description

Technical Field

[0001] This application relates to the field of support, suspension or connection devices for lighting fixtures, and more particularly to a folding head. Background Technology

[0002] Television studios, theaters, performance halls, bars, and mobile performance venues all require stage lighting to create the desired lighting environment. Because stage lighting needs to be frequently adjusted according to the performance content, it is generally installed and fixed in a detachable manner—the lights are hung on rods or trusses using light hooks.

[0003] A lamp hook typically includes a hook body for hooking onto the boom, a clamping device for securing the boom, and a base. On one hand, to allow for angle adjustment of the lamp hook so that it can rotate and be positioned within a certain angle range to meet the fixing needs of different scenarios; on the other hand, to allow the lamp hook to be folded up after installation for convenient storage, packaging, and transportation, a flipping mechanism—a folding head—is also provided between the lamp hook and the lamp.

[0004] The existing folding head includes a first lug and a second lug respectively located on the hook body and the base. The first lug and the second lug are hinged together by a hinge pin. A positioning mechanism is provided between the first lug and the second lug to self-lock the hook body onto the base. The positioning mechanism includes an elongated hole radially located on the hinge pin of the first lug. The second lug has an arcuate surface concentric with the hinge pin, and a limiting groove is provided on the arcuate surface. The arcuate surface of the second lug intersects with the elongated hole on the first lug. A limiting shaft is inserted into the elongated hole and is pulled towards the hinge pin by an elastic member. When the second lug is outside the first lug, the limiting shaft passes through the elongated hole, and both ends of the limiting shaft extend from both sides of the elongated hole and are engaged in the limiting groove. The middle part of the unlocking member is movably hinged to the first lug, and one end of the unlocking member abuts against the inner side of the limiting shaft. When the other end of the unlocking member is manually pressed, the unlocking member pushes the limiting shaft out of the limiting groove under the action of leverage.

[0005] During the state switching process, the elastic component of the existing folding head will continuously deform, and the degree of deformation is large, which can easily lead to elastic failure, thus causing locking failure. Utility Model Content

[0067] The folding head provided in this application includes a first component, a second component, a pressing component, and a resetting component. The first component and the second component are hinged to achieve relative rotation; the pressing component and the second component are hinged to achieve relative rotation; the pressing plate of the pressing component is fixedly connected to a protrusion, and the protrusion is adapted to the first locking position of the first component to form a locking structure. In the pressing state, the first component and the pressing component are rotated together. When the protrusion is aligned with the first locking position, the pressing is released. Under the drive of the resetting component, the pressing component drives the protrusion to rotate into the first locking position and engage with it. Since the pressing component and the second component are hinged, the relative rotation of the first component and the second component is restricted, thereby achieving locking; when an external force is applied to the pressing component, the pressing component overcomes the resetting force of the resetting component and drives the protrusion to rotate in the direction of disengaging from the first locking position. When the protrusion is completely disengaged from the limit of the first locking position, the restriction on the relative rotation of the first component and the second component is released, and the folding head enters a movable state. When locked, the reset component only needs to respond by firmly engaging the protrusion with the first locking position; when a rotational switching state is required, the reset component only needs to remain in the state where the protrusion disengages from the first locking position. Before and after the state switch, the state of the reset component is the same, and during the state switch process, the reset component remains in the same state without continuous deformation, reducing the probability of reset component failure and thus improving the locking stability and reliability of the folding head.

[0090] In existing folding heads, the elastic component undergoes significant deformation during the conversion process as the first lug rotates. Frequent locking and unlocking operations subject this elastic component to continuous stretching and retraction, which can easily lead to damage. Example

[0091] Please see Figures 1 to 14This application provides a folding head, comprising:

[0092] The device comprises a first component 10, a second component 20, a pressing component 30, and a resetting component 40; the first component 10 and the second component 20 are hinged together; the pressing component 30 is hinged to the second component 20; the first component 10 is provided with a first locking position 11.1; the pressing component 30 includes a pressing plate 31 and a protrusion 32, which are fixedly connected; the protrusion 32 is adapted to the first locking position 11.1; the resetting component 40 connects the pressing component 30 to the first component 10 or the second component 20, and is used to drive the protrusion 32 to rotate to the first locking position 11.1.

[0093] It should be noted that:

[0094] The first component 10 and the second component 20 are the basic structural units of the folding head. The first component 10 provides a bearing surface for lamp mounting, and the second component 20 provides a bearing surface for lamp hook mounting. The two are connected by a hinge and together form the main structure of the folding head. The pressing component 30 includes a fixedly connected pressing plate 31 and a protrusion 32, and is hinged to the second component 20. The first locking position 11.1 provided on the first component 10 is adapted to the protrusion 32 of the pressing component 30. The first locking position 11.1 is used to limit the protrusion 32 to prevent the protrusion 32 from disengaging from the first locking position 11.1 when the pressing component 30 is not pressed, thereby limiting the pressing component 30 and thus limiting the rotation of the first component 10 and the second component 20. Its shape is not specifically limited and can be adapted to the protrusion 32, such as a V-groove, a U-groove, etc. Its specific position on the first component 10 is not limited and is set according to the required locking angle of the first component 10 and the second component 20. Additionally, the first locking position 11.1 can also work with other components to limit the protrusion 32 (the following description and accompanying drawings are based on this scenario). When locking the folding head, press the pressing component 30 and rotate it together with the second component 20 until the protrusion 32 aligns with the first locking position 11.1. Then release the pressure, and the pressing component 30 rotates under the drive of the reset component 40, causing the protrusion 32 to embed into the first locking position 11.1 of the first component 10. Since the protrusion 32 is compatible with the first locking position 11.1, and the movement of the protrusion 32 is restricted under the action of the reset component 40, the relative rotation of the first component 10 and the second component 20 is limited, thus achieving locking. When unlocking, apply pressure to the pressing component 30 to make it rotate in the opposite direction, causing the protrusion 32 to rotate away from the first locking position 11.1. At this time, the first component 10 and the second component 20 return to their relative rotation state, thus unlocking the folding head.

[0095] The pressing component 30 is the operational structure for switching the folding head between locked and unlocked states. When the folding head needs to be unlocked, an external force is applied to the pressing plate 31, causing it to overcome the reset force of the reset component 40 and move in the opposite direction to the driving direction of the reset component 40, thus driving the protrusion 32 to rotate away from the first locking position 11.1 on the first component 10. As an operational structure, the shape, size, and material of the pressing plate 31 can be designed according to actual usage requirements and ergonomic principles to provide a comfortable and convenient operating experience. The protrusion 32 is used to cooperate with the first locking position 11.1, and can engage and disengage with the first locking position 11.1 under the action of the pressing plate 31. When the protrusion 32 is completely disengaged from the first locking position 11.1, the restriction on the relative rotation between the first component 10 and the second component 20 is released, and the folding head enters a movable state, facilitating angle adjustment between the components. When the protrusion 32 rotates to the position corresponding to the first locking position 11.1, the external force is removed, the reset component 40 resets, and the driving force generated by it pushes the pressing component 30 to rotate in the opposite direction, so that the protrusion 32 re-engages with the first locking position 11.1. The reset component 40 returns to the first deformation state, and the folding head locks again. The protrusion 32 can be a wedge-shaped structure that fits into the first locking position 11.1, or a columnar structure with a bevel, etc.

[0096] It should be noted that the protrusion 32 and the first locking position 11.1 cooperate through a mechanical locking principle to restrict the clockwise or counterclockwise rotation of the second component 20. Specifically, when the protrusion 32 and the first locking position 11.1 are engaged, their geometric shapes form an interlocking structure: if the second component 20 attempts to rotate clockwise, the protrusion 32 will abut against one side wall of the first locking position 11.1, and the structural boundary of the locking position will prevent the protrusion 32 from moving clockwise, thus restricting the clockwise rotation of the second component 20; if the second component 20 attempts to rotate counterclockwise, the protrusion 32 will contact the other side wall of the first locking position 11.1, and the structural boundary of the other side of the locking position will also prevent the protrusion 32 from moving counterclockwise, thus restricting the counterclockwise rotation of the second component 20. Through this bidirectional abutment restriction, the cooperation between the protrusion 32 and the first locking position 11.1 can prevent the second component 20 from rotating in any direction, ensuring the structural stability of the folding head in the locked state.

[0097] It should be noted that the first deformation state of the reset component 40 is the deformation state when the reset component 40 is not subjected to any externally applied force. In this deformation state, the reset component 40 generates elastic force due to deformation. This elastic force drives the protrusion 32 fixed on the pressing plate 31 to engage with the first locking position 11.1, thereby locking the folding head. When the reset component 40 is in a deformation state driven by an external force, the external force intervenes and overcomes the elastic force of the reset component 40 itself, causing the engagement between the protrusion 32 and the first locking position 11.1 to be released, and the folding head enters a movable or unlocked state.

[0098] The reset component 40, in conjunction with the pressing component 30, the first component 10, and the second component 20, locks the folding head. When it is necessary to unlock the folding head, an external force is applied to the pressing plate 31, causing the reset component 40 to change from a first deformation state (storing a small amount of elastic potential energy) to a second deformation state (storing a larger amount of elastic potential energy). The pressing plate 31 overcomes the elastic force of the reset component 40, causing the protrusion 32 to rotate in the direction of disengaging from the first locking position 11.1. When the protrusion 32 is completely disengaged from the first locking position 11.1, the restriction on the relative rotation of the first component 10 and the second component 20 is released, and the folding head enters a movable state. When the external force is removed, the reset component 40 drives the pressing component 30 to rotate in the opposite direction, causing the protrusion 32 to re-engage with the first locking position 11.1. The reset component 40 returns to the first deformation state, and the folding head is relocked. The reset component 40 can be a torsion spring, a leaf spring, etc. Optionally, the reset component 40 can also be two repulsive magnets, which drive the pressing component to rotate through the repulsive magnetic force to achieve locking.

[0099] It should be noted that one end of the reset component 40 is connected to the pressing component 30, while the other end of the reset component 40 can be connected to the first component 10 or the second component 20 according to actual design requirements. Whether connected to the first component 10 or the second component 20, it provides a reliable force point for the reset component 40, enabling the reset component 40 to effectively apply elastic force, thereby driving the pressing component 30 to rotate.

[0100] The beneficial effects of this embodiment include:

[0101] The folding head includes a first component 10, a second component 20, a pressing component 30, and a resetting component 40. The first component 10 and the second component 20 are hinged to achieve relative rotation; the pressing component 30 and the second component 20 are hinged to achieve relative rotation; the pressing plate 31 of the pressing component 30 is fixedly connected to the protrusion 32, and the protrusion 32 is adapted to the first locking position 11.1 of the first component 10 to form a locking structure. In the pressed state, the first component 10 and the pressing component 30 rotate together. When the protrusion 32 aligns with the first locking position 11.1, the pressing is released. Driven by the reset component 40, the pressing component 30 drives the protrusion 32 to rotate into the first locking position 11.1 and engage with it. Since the pressing component 30 is hinged to the second component 20, the relative rotation of the first component 10 and the second component 20 is restricted, thus achieving locking. When an external force is applied to the pressing component 30, the pressing component 30 overcomes the reset force of the reset component 40 and drives the protrusion 32 to rotate in the direction of disengaging from the first locking position 11.1. When the protrusion 32 completely disengages from the limit of the first locking position 11.1, the restriction on the relative rotation of the first component 10 and the second component 20 is released, and the folding head enters the movable state. When locked, the reset component 40 only needs to respond by firmly engaging the protrusion 32 with the first locking position 11.1; when a rotational switching state is required, the reset component 40 only needs to remain in the state where the protrusion 32 is disengaged from the first locking position 11.1. Before and after the state switch, the state of the reset component 40 is the same, and during the state switch process, the reset component 40 remains in the same state without continuous deformation, reducing the probability of failure of the reset component 40, thereby improving the locking stability and reliability of the folding head.

[0102] Specifically, in order to hinge the first component 10 and the second component 20, the folding head is also provided with assembly bolts 50; the first component 10 includes a first side plate 11 and a second side plate 12 that are parallel to each other, with the first side plate 11 and the second side plate 12 spaced apart and opposite each other; the direction from the first side plate 11 to the second side plate 12 is the first direction; the first side plate 11 and the second side plate 12 are both provided with first locking positions 11.1; the second component 20 includes a third side plate 21 and a fourth side plate 22 that are parallel to each other, with the third side plate 21 and the fourth side plate 22 spaced apart and opposite each other; the first side plate 11 and the second side plate 12 are located between the third side plate 21 and the fourth side plate 22, and the first side plate 11 is parallel to the third side plate 21; the first side plate 11, the second side plate 12, the third side plate 21 and the fourth side plate 22 are all provided with first assembly holes 11.2 that extend along the first direction and correspond to each other; the assembly bolts 50 pass through the four first assembly holes 11.2. Thus, by opening first assembly holes 11.2 extending in the first direction and corresponding to each other on each of the four side plates, assembly bolts 50 pass through the four first assembly holes 11.2, hinged together the first component 10 and the second component 20. In this embodiment, the direction from the first side plate 11 to the second side plate 12 is taken as the left-right direction, such as... Figures 10 to 11As shown, both the first component 10 and the second component 20 adopt a U-shaped structural design. The first component 10 includes a first side plate 11 and a second side plate 12. The first side plate 11 and the second side plate 12 are flat structures of the same shape and size. The right side surface of the first side plate 11 is parallel to and spaced apart from the left side surface of the second side plate 12. A first assembly hole 11.2 penetrating in the left-right direction is provided in the middle of both the first side plate 11 and the second side plate 12. A first locking position 11.1 of the same shape and size is provided on the upper end surface of both the first side plate 11 and the second side plate 12. Similarly, the second component 20 includes a third side plate 21 and a fourth side plate 22. The third side plate 21 and the fourth side plate 22 are flat structures of the same shape and size. The right side surface of the third side plate 21 is parallel to and spaced apart from the left side surface of the fourth side plate 22. A first assembly hole 11.2 penetrating in the left-right direction is also provided in the middle of both the third side plate 21 and the fourth side plate 22. Figure 1 As shown, the distance between the third side plate 21 and the fourth side plate 22 is greater than the distance between the first side plate 11 and the second side plate 12, forming a nested layout. The two side plates of the first component 10 are located between the two side plates of the second component 20, so that the four first assembly holes 11.2 form a coaxial channel. The assembly bolt 50 consists of a bolt body 52 and an assembly nut 51. The bolt body 52 passes through the four first assembly holes 11.2 in sequence, and the end is fastened by the assembly nut 51, which hinges the first component 10 and the second component 20, allowing the first component 10 and the second component 20 to rotate relative to each other.

[0103] Specifically, to connect the first side plate 11 and the second side plate 12, the first component 10 further includes a first connecting plate 13, which is fixedly connected to the first end face of the first side plate 11 and the second side plate 12. The first end face is parallel to the first direction and located outside the gap between the third side plate 21 and the fourth side plate 22. To connect the third side plate 21 and the fourth side plate 22, the second component 20 further includes a second connecting plate 23, which is fixedly connected to the first side face of the third side plate 21 and the fourth side plate 22. When the reset component 40 is in the first deformed state, the first side face is parallel to the first end face and located outside the gap between the first side plate 11 and the second side plate 12. Thus, the first side plate 11 and the second side plate 12 are fixedly connected by the first connecting plate 13, and the third side plate 21 and the fourth side plate 22 are fixedly connected by the second connecting plate 23. Furthermore, the first connecting plate 13 and the second connecting plate 23 provide an installation base for connecting the folding head to the lamp fixture and the lamp hook, respectively, ensuring that the first connecting plate 13 supports the lamp fixture and the second connecting plate 23 supports the lamp hook. In this embodiment, as... Figure 11 As shown, the first connecting plate 13 at the bottom connects the lower surfaces of the first side plate 11 and the second side plate 12, and the second connecting plate 23 at the top connects the upper surfaces of the third side plate 21 and the fourth side plate 22. For safety reasons, the joints between the side plates and the connecting plates are rounded. Figure 1 As shown, when the torsion spring (the reset component 40 in this embodiment) is in the first deformation state, the first side plate 11, the second side plate 12, the third side plate 21 and the fourth side plate 22 are all in the interval between the first connecting plate 13 and the second connecting plate 23, and the first connecting plate 13 and the second connecting plate 23 are parallel.

[0104] Optimization of the pressing component: The spacing between the pressing plate 31 and the third side plate 21 and the fourth side plate 22 corresponds; the protrusion direction of the protrusion 32 forms an obtuse angle with the plate surface of the pressing plate 31 near the assembly bolt 50; the protrusion 32 is located at the end of the pressing plate 31 near the second connecting plate 23; when the reset component 40 is in the first deformation state, the plate surface of the pressing plate 31 is parallel to the first direction and forms an acute angle with the second direction, the second direction is perpendicular to the first direction and parallel to the first connecting plate 13, and the protrusion 32 engages with the first locking position 11.1. Thus, a structural design is adopted in which the protrusion 32 and the pressing plate 31 are connected at an obtuse angle. When the protrusion 32 engages with the first locking position 11.1, the pressing plate 31 forms an ergonomic pressing surface. When an external force is applied to the pressing plate 31, the protrusion 32 effectively overcomes the elastic force and disengages from the first locking position 11.1, realizing the quick unlocking of the folding head. In this embodiment, as Figure 1 As shown, the pressing plate 31 is located outside the gap between the third side plate 21 and the fourth side plate 22. Figure 8 As shown, the protrusion 32 consists of two flat plates of the same shape and size, respectively fixedly connected to the upper ends of the left and right sides of the pressing plate 31. The protruding direction of the protrusion 32 forms an obtuse angle with the inner surface of the pressing plate 31 (the surface near the assembly bolt 50), and the protrusion 32 is fixed to the end of the pressing plate 31 near the second connecting plate 23. The end of the protrusion 32 away from the pressing plate is adapted to the first locking position 11.1. The lower surface of the protrusion 32 has a downwardly protruding arc-shaped protrusion at the end away from the pressing plate 31. Figure 4 As shown, the front-back direction is the first direction, and the left-right direction is the second direction. When the reset component 40 is in the first deformation state, the surface of the pressing plate 31 is parallel to the first direction and forms an acute angle with the second direction, and the protrusion 32 engages with the first locking position 11.1.

[0105] Specifically, to connect the pressing component 30 and the second component 20, the folding head is also provided with an assembly shaft 60; two protrusions 32 near the pressing plate, the third side plate 21, and the fourth side plate 22 are all provided with corresponding second assembly holes 21.1 extending in the first direction; the assembly shaft 60 passes through the four second assembly holes 21.1, rotatably connecting the reset component 40 to the assembly shaft 60. Thus, by passing the assembly shaft 60 through the second assembly holes 21.1 of the protrusions 32, the third side plate 21, and the fourth side plate 22, the protrusions 32 are hinged to the third side plate 21 and the fourth side plate 22, thereby achieving a hinge connection between the pressing component 30 and the second component 20. In this embodiment, as... Figure 10 As shown, both the third side plate 21 and the fourth side plate 22 have corresponding second assembly holes 21.1 at their upper ends. Figure 8 As shown, a second assembly hole 21.1 is also provided on the protrusion 32. Figure 3 As shown, these second assembly holes 21.1 all extend along the first direction and are positioned correspondingly. The assembly shaft 60 passes through all the aforementioned second assembly holes 21.1 in sequence, hinged together with the third side plate 21, the fourth side plate 22, and the protrusion 32. Furthermore, as... Figures 4 to 7 As shown, the reset component 40 in this embodiment can be a torsion spring, and its spring body 43 is rotatably connected to the assembly shaft 60.

[0106] Specifically, to connect the reset component 40 to the pressing component 30 and the first component 10 or the second component 20, the reset component 40 can be a torsion spring; the torsion spring includes a first torsion arm 41, a second torsion arm 42, and a spring body 43; the spring body 43 is hinged to the assembly shaft 60; the first torsion arm 41 abuts against the side of the second connecting plate 23 corresponding to the first connecting plate 13; the second torsion arm 42 abuts against the side of the pressing plate 31 corresponding to the assembly bolt 50. Thus, the first torsion arm 41 and the second torsion arm 42 abut against the second connecting plate 23 and the pressing plate 31 respectively, realizing the connection between the reset component 40, the pressing component 30, and the first component 10. Therefore, the reset force of the reset component can drive the pressing component to rotate when not pressed, thereby driving the protrusion to turn towards the first locking position. In this embodiment, as... Figure 9 As shown, the reset component 40 uses a torsion spring, which consists of a first torsion arm 41, a second torsion arm 42, and a spring body 43. Figure 4 As shown, the spring body 43 of the torsion spring is sleeved on the assembly shaft 60. The first torsion arm 41 of the torsion spring abuts against the side of the second connecting plate 23 corresponding to the side of the first connecting plate 13. At the same time, the second torsion arm 42 of the torsion spring abuts against the side of the pressing plate 31 corresponding to the side of the assembly bolt 50.

[0107] Specifically, the folding head is also provided with a limiting shaft 70; the first side plate 11 and the second side plate 12 are also provided with third assembly holes 11.3 extending along the first direction and corresponding to each other; the limiting shaft 70 passes through all the third assembly holes 11.3; the third side plate 21 and the fourth side plate 22 are both provided with second locking positions 21.2, the second locking positions 21.2 are located at the end of the second side away from the second connecting plate 23, the second side is perpendicular to the first side, and the second side is close to the pressing plate 31; when the reset component 40 is in the first deformation state, the limiting shaft 70 engages with the second locking position 21.2; the first locking position 11.1 is an obtuse-angled first locking position 11.1 opened on the first side plate 11 and the second side plate 12; the opening of the first locking position 11.1 faces the limiting shaft 70; the first locking position 11.1 is located on the second end face of the first side plate 11 and the second side plate 12, and the second end face is parallel to the first end face. Thus, when the reset component 40 is in the first deformed state, the limiting shaft 70 engages with the second locking position 21.2, restricting the rotation of the folding head in one direction, and the protrusion 32 engages with the first locking position 11.1, restricting the rotation of the folding head in the other direction, thereby achieving locking of the folding head in both rotational directions. Through the engagement relationships of the limiting shaft 70 and the second locking position 21.2, and the protrusion 32 and the first locking position 11.1—two sets of different positions and structures—the rotation of the folding head is restricted from two directions respectively, thereby achieving locking of the folding head in both rotational directions. In this embodiment, as... Figure 11 As shown, the direction from the first side plate 11 to the second side plate 12 is left-right. A third assembly hole 11.3 is provided at the lower front end of the left side plate 11, and a corresponding third assembly hole 11.3 is also provided at the lower front end of the right side plate 12. The obtuse-angled structure cut out at the upper end of the first side plate 11 and the second side plate 12 is the first locking position 11.1, with its opening facing the side of the third assembly hole 11.3. Figure 10 As shown, taking the direction from the third side plate 21 to the fourth side plate 22 as the left-right direction, the lower front end of the left third side plate has a downward-facing second locking position 21.2, and the right fourth side plate 22 also has a corresponding second locking position 21.2. Figure 3 As shown, the limiting shaft 70 located at the lower end passes through the third assembly hole 11.3 of the first side plate 11 and the second side plate 12.

[0108] Specifically, in order to relock the second component 20 after the folding head is unlocked and rotated to a specific angle, obtuse-angled third locking positions 11.4 are provided on the third end faces of the first side plate 11 and the second side plate 12, with the third end face perpendicular to the first end face. When the reset component 40 is in the first deformed state, the third end face is located away from the pressing plate 31. The first side plate 11 and the second side plate 12 are also provided with arc surfaces 11.5. The first locking position 11.1 and the third locking position 11.4 are connected by the arc surface 11.5. Thus, when an external force drives the pressing plate to rotate toward the assembly bolt at the end away from the assembly axis, it causes the protrusion 32 to rotate away from the first locking position 11.1, releasing the rotation restriction on the second component 20, allowing the second component to rotate. During the rotation, the arc surface 11.5 provides a smooth movement path for the protrusion 32, allowing the protrusion 32 to move along the arc surface 11.5 as the second component 20 rotates. When the second component 20 rotates to a specific angle, the protrusion 32 engages with the third locking position 11.4, thereby being locked in the new position. In this embodiment, as... Figure 11 As shown, the direction from the first side plate 11 to the second side plate 12 is the left-right direction, and the direction parallel to the first connecting plate is the front-back direction. Openings are provided on the rear surface of both the left side plate 11 and the right side plate 12; these openings are the third locking position 11.4. Figure 12 As shown, an arc surface 11.5 is also provided between the first locking position 11.1 and the third locking position 11.4 of the first side plate 11. A corresponding arc surface 11.5 is also provided between the first locking position 11.1 and the third locking position 11.4 of the second side plate 12, and the arc surface 11.5 connects the first locking position 11.1 and the third locking position 11.4.

[0109] Specifically, for connecting the light fixture, the first connecting plate 13 has a first connecting hole 13.1 that penetrates vertically through the plate surface; the first connecting hole 13.1 is fitted with a first connecting bolt 80; the first connecting bolt 80 is used to connect the light fixture. Thus, by providing the first connecting hole 13.1 in the first connecting plate 13 and using the first connecting bolt 80, the light fixture can be connected. In this embodiment, the first connecting plate 13 has a first connecting hole 13.1 on its surface, which is adapted to the first connecting bolt 80, and this hole can be used for bolt connection with the light fixture.

[0110] Specifically, for connecting the lamp hook, the second connecting plate 23 has a second connecting hole 23.1 penetrating the plate surface; the second connecting hole 23.1 is fitted with a second connecting bolt 90; the second connecting bolt 90 is used to connect the lamp hook. Thus, by providing the second connecting hole 23.1 in the second connecting plate 23 and using the second connecting bolt 90, the lamp hook can be connected. In this embodiment, the second connecting hole 23.1 is located in the center of the second connecting plate 23, and this hole is adapted to the second connecting bolt 90 for bolt connection with the lamp hook.
