Description

Technical Field

[0001] This utility model relates to a connecting device, specifically to a lifting component connecting module and a lifting component connecting module. Background Technology

[0002] Stage lighting creates a sense of space and time on stage and is an indispensable part of stage performances. Currently, when installing stage lighting fixtures, foldable lamp hooks that do not need to be disassembled are usually used to fix and support the fixtures, forming chandeliers. These foldable lamp hooks that do not need to be disassembled generally include a hanging bracket connection module that can connect the lamp hook to the fixture, and the lamp hook can be folded and set on the hanging bracket connection module.

[0003] For example, Figure 1 This diagram illustrates a three-dimensional structure of a folding hook and chandelier base assembly using existing technology. One end of the hanging component connecting module 10 is pivotally connected to the folding hooks 18 and 19, while the other end is fixedly connected to the chandelier base 15. The chandelier base 15 directly supports the light source and controls the direction of light emission. The folding hooks 18 and 19 can be folded and accommodated on one side surface of the chandelier base 15.

[0004] Figure 2 A three-dimensional structural diagram of a lifting component connection module 10 of the prior art is shown. Figure 3 An exploded perspective view of a lifting component connection module 10 from the prior art is shown. (See attached diagram.) Figure 2 As shown, the lifting component connection module 10 includes a limiting member 11, a connecting member 13, and a fixing plate 12. The limiting member 11 and the connecting member 13 are assembled as one unit and then fixed to the surface of the fixing plate 12. The connecting member 13 is sandwiched between the limiting member 11 and the fixing plate 12.

[0005] like Figure 2 and Figure 3 As shown, the limiting member 11 includes a first sidewall 111, a connecting wall 112, a second sidewall 113, a first slot 118, and a first protrusion 119 arranged sequentially. The first sidewall 111 and the second sidewall 113 are arranged parallel to each other and spaced apart. The two ends of the connecting wall 112 are respectively connected to one end of the first sidewall 111 and the second sidewall 113. The other ends of the first sidewall 111 and the second sidewall 113 are suspended and form a semi-enclosed structure resembling a "ㄈ" shape. A first limiting hole 115 is provided on the first sidewall 111, and a second limiting hole 117 is provided on the second sidewall. The first limiting hole 115 and the second limiting hole 117 are opposite to each other and coaxially arranged. The first slot 118 is provided on the connecting wall 112. A plurality of first protrusions 119 are respectively provided on one end surface of the first sidewall 111 and the second sidewall 113.

[0006] The connector 13 includes a first body 130, a pivot hole 131, a lifting hole 133, a second slot 138, and a second protrusion 139. The pivot hole 131 and the lifting hole 133 are disposed in and pass through the body 130. The second slot 138 is disposed between the pivot hole 131 and the lifting hole 133. The second protrusion 139 is disposed on one end surface of the body 130.

[0007] The mounting plate 12 includes a plurality of first mounting holes 121, second mounting holes 123, and two spaced mounting holes 125. The first mounting holes 121 are fitted and fixed together with the first protrusion 119. The second mounting holes 123 are fitted and fixed together with the second protrusion 139. The two mounting holes 125 are used for fixing to the lighting fixture housing.

[0008] When the limiting member 11, the connecting member 13 and the fixing plate 12 are assembled as a whole, the first limiting hole 115, the pivot hole 131 and the second limiting hole 117 are located on the same axis.

[0009] To meet the different size design requirements of chandeliers and effectively fix the chandeliers and control their light output direction, the assembly method between the folding hooks and the chandelier base is usually divided into a split assembly structure or an integrated assembly structure, based on the number and relative positional relationship between the folding hooks and the hanging component connection modules.

[0010] The so-called split assembly structure: there are two hanging component connecting modules 10. Folding hooks 18 and 19 are movably assembled with one of the hanging component connecting modules 10 and then fixed to the chandelier base 15. Simultaneously, the two hanging component connecting modules 10 are spaced apart on the surface of the chandelier base 15 and are independent of each other, such as... Figure 1 As shown, this modular assembly structure is generally suitable for chandeliers with smaller base sizes (15).

[0011] The so-called integrated assembly structure: There are two folding hooks, and the entire lifting component connecting module 20 is a single integrated structure, such as... Figure 4 As shown, this is suitable for chandeliers with a 15-inch base. See also: Figure 4 As shown, the hanging component connection module 20 includes two limiting members 25 and fixing plates 271 and 273. The two limiting members 25 are fixed to the surfaces of the fixing plates 271 and 273. The openings are symmetrically arranged. Mounting holes 2711 and 2731 are machined on the fixing plate 271. The mounting holes 2711 and 2731 are used for fixing to the lighting fixture housing.

[0012] Figure 5 A three-dimensional structural diagram of a lifting component connection module 30' of the prior art is shown. Figure 6 Showing Figure 5 The diagram shows a cross-sectional view of the lifting component connection module 30'. Figure 7 Showing Figure 5The diagram shows the disassembled structure of the lifting component connection module 30'. (See attached diagram.) Figures 5 to 7 As shown, a hook connecting member 31 is rotatably connected to the lamp connecting member 35'. The lamp connecting member 35' has a first mounting hole 354' and a second mounting hole 355' integrally formed or machined on it. The first mounting hole 354' and the second mounting hole 355' are used to fix the lamp connecting member 35' to the chandelier base. The hook connecting member 31' has a first pivot hole 3111' integrally formed or machined on it. The first pivot hole 3111' is used to rotatably connect the hook connecting member 31' to the folding hook 18.

[0013] Figure 8 The invention showcases a lifting module 30' that incorporates a folding hook 18, which is pivotally connected to a hook-body lifting component 31'.

[0014] However, the above structure still has the following drawbacks:

[0015] Defect 1: The hanging component connection module 10 has many different connection dimensions L with the lamp base 15, so its fixing plate has to be made in many different ways, resulting in poor versatility.

[0016] Defect 2: Lifting component connecting modules 10 and 20. In order to ensure the strength of the parts, the parts are generally made of metal, such as stainless steel. The parts are all processed by welding, which is time-consuming and labor-intensive and not suitable for mass production.

[0017] Defect 3: For the lifting component connecting modules 10 and 20, since the parts are interlocking structures and are welded together before surface treatment, the joints of the interlocking structures cannot be properly treated, which easily leads to rust and affects the appearance of the product.

[0018] Defect 4: Hanging component connection module 30'. Because the hook body connecting hanging component 31' can rotate relative to the lamp connecting hanging component 35', the hook body connecting hanging component 31' is prone to swaying relative to the lamp connecting hanging component 35', which in turn causes the chandelier connected through this hanging component connection module 30' to be prone to swaying.

[0019] Therefore, it is necessary to provide a new lifting component connection module to solve the aforementioned technical problems of poor versatility, poor stability, and unsuitability for mass production. Utility Model Content

[0020] To address at least one of the aforementioned problems, this application provides a hanging component connection module. The hanging component connection module includes a hook connection module, a lamp connecting hanging component, and a first elastic member; wherein the lamp connecting hanging component is used to connect to or be integrally formed with a lamp; the hook connection module is pivotally mounted on the lamp connecting hanging component about a first pivot axis, and clamps the first elastic member between the hook connection module and the lamp connecting hanging component.

[0021] Because the first elastic element is elastic, even when the hook connecting module and the lamp connecting pendant are pivotally connected around the first pivot axis and the first elastic element is clamped, the hook connecting module and the lamp connecting pendant can still rotate relative to each other around the first pivot axis through the elastic deformation of the first elastic element when a large torque is applied to the hook connecting module or the lamp connecting pendant. Moreover, when no large torque is applied to the lamp connecting pendant relative to the hook connecting module, the lamp connecting pendant remains stationary relative to the hook connecting module, avoiding wobbling of the lamp connecting pendant relative to the hook connecting module during use and ensuring the stability of the pendant connecting module. In addition, when the connection size L of the lamp base has multiple specifications, the lamp connecting pendant can be rotated relative to the hook connecting module around the first pivot axis to a position corresponding to the mounting hole of the lamp base. This allows a single specification of lamp connecting pendant to be adapted to lamp bases of multiple connection sizes L without changing the orientation of the two hooks, thereby improving the versatility of the pendant connecting module.

[0022] In some embodiments, the first elastic element is an elastic washer, with its concave surface facing the lamp connecting bracket and its convex surface facing away from the lamp connecting bracket. This allows for pre-tightening of the hook connecting module and the lamp connecting bracket when the elastic washer is clamped between them. Unless a large torque is applied to the hook connecting module and the lamp connecting bracket, the hook connecting module will not rotate relative to the lamp connecting bracket, thus ensuring the stability of their relative positions and the structural stability of the bracket connecting module.

[0023] In some implementations, the hook connection module includes a hook connection lifting component.

[0024] In some embodiments, the hook-connecting hanger includes a first bottom surface for pivotally connecting to the lighting fixture connecting hanger about a first pivot axis; and a first side surface fixed relative to the first bottom surface for connecting to the hook body. Because the first bottom surface and the first side surface are respectively provided for connecting to the lighting fixture connecting hanger and the hook body, mutual interference between the lighting fixture connecting hanger and the hook body during movement is avoided. Furthermore, since the first side surface is fixed relative to the first bottom surface, it can be integrally formed with the first bottom surface using molding or bending of sheet metal parts, which reduces labor intensity, improves production efficiency, and ensures connection strength.

[0025] In some embodiments, the hook connection module also includes a limiting part connected to the hook connection lifting component.

[0026] In some embodiments, the limiting portion is fixed relative to at least one of the first side and the first bottom surface. The first side is configured to allow the hook body connected thereto to pivot about a second pivot axis relative to the first side. The limiting portion and the first bottom surface form an angle-limiting structure that limits the range of the angle of rotation of the hook body about the second pivot axis relative to the first side. Thus, the angle of rotation of the hook body about the second pivot axis relative to the first side can be limited by the included angle between the limiting portion and the first bottom surface.

[0027] In some embodiments, the first side includes a first side portion and a second side portion, which are respectively fixedly disposed opposite to the two opposite sides of the first bottom surface, so that the first side portion, the first bottom surface, and the second side portion together form an approximately "U"-shaped structure. Thus, the hook body can be pivotally connected to the first side portion and the second side portion via a second pivot axis, thereby improving the stability of the hook body pivot connection; moreover, the "U"-shaped profile structure ensures the small and compact structure of the hook body connection module, achieving miniaturization and weight reduction.

[0028] In some preferred embodiments, a pivot hole is provided on the first side for pivotal connection with the hook body. The central axis of the pivot hole is parallel to the central axis of the second pivot axis around which the hook body pivots about the first side, but not parallel to the central axis of the first pivot axis. Therefore, when the hanging component connecting module connects the hook body to the lamp, the lamp can rotate relative to the hook body around the first and second pivot axes, thereby improving the flexibility of lamp angle adjustment.

[0029] In some embodiments, the limiting part and the first bottom surface are fixed relative to each other by means of a snap-fit ​​structure, so that the limiting part and the first bottom surface form an "L" shape. This restricts the hook body from rotating within a 90° range around the second pivot axis. Furthermore, the "L"-shaped profile structure ensures the small and compact size of the hook body connection module, achieving miniaturization and weight reduction. In addition, the snap-fit ​​connection simplifies the connection operation and improves installation efficiency. Moreover, the limiting part, the first bottom surface, and the first side surface can be surface-treated before assembly to avoid the problem of incomplete surface treatment after assembly, which can lead to easy rusting.

[0030] In some embodiments, the limiting part is fixed relative to the first side as follows: the limiting part is connected to at least one of the first side and the second side of the first side through an engaging structure, so that the first side, the limiting part, and the second side form a "U"-shaped structure. This improves the stability of the first and second sides through the limiting part; moreover, the "U"-shaped profile structure ensures the small and compact structure of the hook connection module, achieving miniaturization and weight reduction; furthermore, the engaging connection simplifies the connection operation and improves installation efficiency.

[0031] In some preferred embodiments, the end of the limiting portion that engages with the first side facing away from the first bottom surface is flush with the end of the first side facing away from the first bottom surface. This ensures the compactness of the structure connecting the limiting portion to the first side.

[0032] In some embodiments, the limiting part and the first bottom surface are connected by an engaging structure: one of the limiting part and the first bottom surface is provided with a first protrusion, and the other is provided with a first mounting hole that mates with the first protrusion. Thus, the limiting part and the first bottom surface can be engaged and connected by the first protrusion fitting into the first mounting hole.

[0033] In some embodiments, the limiting part is connected to the first side and the second side via an engaging structure: the limiting part is provided with a second protrusion and a third protrusion, and the first side and the second side are respectively provided with a first groove and a second groove that mate with the second protrusion and the third protrusion. Thus, the limiting part can be quickly engaged with the first groove and the second groove via the second protrusion and the third protrusion, respectively. Furthermore, the limiting part connected to the first side and the second side can withstand the resistance force of the hook without wobbling.

[0034] In some preferred embodiments, the first slot and the second slot are respectively disposed at the ends of the first side and the second side that are opposite to the first bottom surface. Thus, by placing the limiting part on the first side and the second side, a quick-locking connection between the limiting part and the first side and the second side can be achieved.

[0035] In some embodiments, a reinforcing plate is provided on the side of the lamp connecting pendant facing the hook connecting module, and the reinforcing plate is located on the side of the limiting portion opposite to the first side. This allows the reinforcing plate to provide support to at least one of the first side, the first bottom surface, and the limiting portion, improving the stability of the limiting portion as an angle-limiting structure. Preferably, the reinforcing plate abuts against at least one of the first side, the first bottom surface, and the limiting portion, and the reinforcing plate is located on the side opposite to the opening formed between the first bottom surface and the limiting portion. More preferably, the reinforcing plate has a notch on the side of the limiting portion opposite to the hook connecting module, or a clearance portion is provided on at least one of the first side, the first bottom surface, and the limiting portion, to ensure that the hook connecting module can rotate 360° relative to the lamp connecting pendant around the first pivot axis, thus preventing the reinforcing plate from obstructing the rotation of the hook connecting module when the hook connecting module and the lamp connecting pendant rotate relative to each other around the first pivot axis.

[0036] In some embodiments, the hook connecting module is pivotally connected to the lamp connecting hanger via a first connecting bolt, the central axis of the first connecting bolt being parallel to the central axis of the first pivot axis. Pivoting the hook connecting module to the lamp connecting hanger via the first connecting bolt improves connection efficiency. Furthermore, the hook connecting module and the lamp connecting hanger can be surface-treated before assembly to avoid rusting due to incomplete surface treatment after assembly. Preferably, the end of the first connecting bolt located on the lamp connecting hanger opposite to the hook connecting module has an anti-detachment structure to prevent the first connecting bolt from falling off the lamp connecting hanger. This prevents the first connecting bolt from falling off the lamp connecting hanger, improving the structural stability of the hanger connecting module. Preferably, at least one of the hook connecting module, the first elastic member, and the lamp connecting hanger has a mating hole adapted to the first connecting bolt. Therefore, when the first connecting bolt pivotally connects the hook connecting module to the lamp connecting hanger, it passes through the mating holes on the first bottom surface, the first elastic element, and the lamp connecting hanger. This prevents the hook connecting module, the first elastic element, and the lamp connecting hanger from falling off after pivoting. More preferably, the mating hole on the lamp connecting hanger is a first threaded hole for threaded connection with the first connecting bolt. Thus, the lamp connecting hanger can also act as a nut for the first connecting bolt, improving the stability of the connection between the lamp connecting hanger and the hook connecting module. When the lamp connecting hanger is only a nut structure, this hanger connecting module is suitable for lamps with only one connecting hole. Even more preferably, the lamp connecting hanger includes a plate-like first hanger body, and the first hanger body extends to form a second boss on at least one of the two sides: the side facing the hook connecting module and the side away from the hook connecting module. The first threaded hole passes through the second boss. Therefore, the lamp connecting hanger can largely maintain a plate-like structure to reduce its weight, and a threaded hole can be drilled at the location of the second boss to realize the nut function of the lamp connecting hanger. That is, the lamp connecting hanger can realize its nut function without increasing its weight too much.

[0037] In some embodiments, the luminaire connecting pendant is provided with mounting holes for connecting to luminaires. Therefore, when the connection size L of the luminaire base has multiple specifications, the luminaire connecting pendant and the hook body connecting module can be rotated relative to each other around a first pivot axis to the mounting hole position on the luminaire base. This allows a single specification of luminaire connecting pendant to be adapted to luminaire bases of multiple connection sizes L without changing the orientation of the two hooks, thereby improving the versatility of the pendant connecting module.

[0038] According to another aspect of this application, a lifting component connection module is provided. This lifting component connection module includes the aforementioned lifting component connection module; and a hook body adapter for pivotally connecting the hook body connection module and the hook body around a second pivot axis and / or a third pivot axis; wherein the third pivot axis is arranged parallel to the first pivot axis. Therefore, when the hook body can rotate relative to the lighting fixture connection component of the lifting component connection module around the first, second, and third pivot axes, the position of the hook body relative to the lighting fixture connection component can be adjusted in three-dimensional space, improving the flexibility of hook body adjustment; furthermore, the hook body connection module, the lighting fixture connection component, and the hook body adapter can be surface-treated before assembly to avoid the problem of easy rusting caused by incomplete surface treatment of parts after assembly.

[0039] In some embodiments, the hook-body adapter includes a second side for pivotally connecting to the hook-body connection module about a second pivot axis; and a second bottom surface for pivotally connecting to the hook body about a third pivot axis. Thus, the hook body can rotate relative to the lighting fixture connection component of the adapter connection module about the first, second, and third pivot axes.

[0040] In some preferred embodiments, the second side includes a third side and a fourth side, which are fixedly disposed opposite to the two opposite sides of the second bottom surface, so that the hook body adapter forms an approximately "U"-shaped structure. Thus, the hook body can be pivotally connected to the third and fourth sides respectively via a second pivot axis, improving the stability of the hook body pivot connection; moreover, the "U"-shaped profile structure ensures the small and compact structure of the hook body adapter, achieving miniaturization and lightweight design.

[0041] In some preferred embodiments, a second elastic element is provided between the third and fourth sides. This allows for a preload between the third and fourth sides and the first and second sides under the elastic force of the second elastic element. When no large torque is applied to the first, second, third, and fourth sides, they remain relatively stationary, ensuring the stability of the relative position between the hook body adapter and the hook body connection module.

[0042] In some embodiments, the hook adapter is pivotally connected to the hook connection module via a second connecting bolt and a second nut, with the central axis of the second connecting bolt parallel to the central axis of the second pivot axis. This allows for a quick and detachable connection between the hook adapter and the hook connection module. Attached Figure Description

[0074] Example 1

[0075] Figures 9 to 12 A first embodiment of the hanging component connecting module 30 of this application is shown as an example. The hanging component connecting module 30 is a connector for connecting a folding hook body and a stage lighting fixture base. The hanging component connecting module 30 includes a hook body connecting module, a first elastic member, a lighting fixture connecting hanging component 35, and a first connecting bolt 33. The lighting fixture connecting hanging component 35 is used to connect to or be integrally formed with a lighting fixture. The hook body connecting module is pivotally mounted on the lighting fixture connecting hanging component 35 via the first connecting bolt 33 about a first pivot axis, and clamps the first elastic member between the hook body connecting module and the lighting fixture connecting hanging component 35.

[0076] Because the first elastic element is elastic, when a large torque is applied to the hook connecting module or the lamp connecting pendant 35, the hook connecting module and the lamp connecting pendant 35 can rotate relative to each other around the first pivot axis through the elastic deformation of the first elastic element. Moreover, when no large torque is applied to the lamp connecting pendant 35 relative to the hook connecting module, the lamp connecting pendant 35 remains stationary relative to the hook connecting module, avoiding wobbling of the lamp connecting pendant 35 relative to the hook connecting module during use and ensuring the stability of the pendant connecting module 30. In addition, when the connection size L of the lamp base has multiple specifications, the lamp connecting pendant 35 can be rotated relative to the hook connecting module around the first pivot axis to a position corresponding to the mounting hole of the lamp base. This allows a single specification of lamp connecting pendant 35 to be adapted to lamp bases of multiple connection sizes L without changing the orientation of the two hooks, thereby improving the versatility of the pendant connecting module 30.

[0077] like Figure 12 As shown, the hook connection module includes a hook connection lifting component 31, which includes a first bottom surface 312. A first side edge 310 is integrally formed (e.g., by die stamping or bending a sheet metal part) or machined onto the first bottom surface 312. Therefore, by using die stamping or bending a sheet metal part to prepare an integral first side edge 310 and first bottom surface 312, the connection strength can be guaranteed.

[0078] In some preferred embodiments, such as Figures 9 to 12 As shown, the hook connection module also includes a limiting part 32. A first mounting hole 3121 and a second mounting hole 3122 are integrally formed or machined on the first bottom surface 312; a slot is integrally formed or machined on the first side edge 310. The limiting part 32 includes a second body 320, on which protrusions are integrally formed or machined, respectively engaging with the first mounting hole 3121 and the slot, wherein the protrusion engaging with the first mounting hole 3121 is the first protrusion 321. The second mounting hole 3122 is a mounting hole for pivotally connecting the first bottom surface 312 to the lamp connecting pendant 35 or the lamp around a first pivot axis. Since the limiting part 32 is connected to the first side 310 and the first bottom surface 312 by a snap-fit ​​connection, the assembly process is not only labor-saving and quick, thereby improving production efficiency, product lifespan and product aesthetics; the limiting part 32, the first bottom surface 312 and the first side surface 310 can also be surface-treated before assembly, so as to avoid the problem of easy rusting caused by incomplete surface treatment of parts after assembly.

[0079] In some preferred embodiments, such as Figure 12 As shown, the first mounting hole 3121 is non-circular to restrict the rotation of the limiting part 32, which engages with the first protrusion 321 in the first mounting hole 3121, relative to the first bottom surface 312.

[0080] In some preferred embodiments, such as Figure 12 As shown, the first protrusion 321 is located at the center of the lower end face of the second body 320.

[0081] In some preferred embodiments, such as Figure 12 As shown, the second mounting hole 3122 is a through hole that penetrates the first bottom surface 312, so that the first bottom surface 312 can be connected to the lamp connecting pendant 35 by rotating relative to the first pivot axis through the second mounting hole 3122 (through which the first connecting bolt passes).

[0082] In some preferred embodiments, such as Figure 9 As shown, the end of the limiting part 32 that engages with the first side 310 that is opposite to the first bottom surface 312 is flush with the end of the first side 310 that is opposite to the first bottom surface 312. This ensures the compactness of the structure connecting the limiting part 32 and the first side 310.

[0083] In some preferred embodiments, reference continues to be made to Figures 10 to 12 As shown, the first side 310 is configured to allow a hook (e.g., a folding hook 18) attached thereto to pivot about a second pivot axis relative to the first side 310. This is because the limiting part 32 engages with the first mounting hole 3121 of the first bottom surface 312 via the first protrusion 321, and with the slots of the first side 310 via other protrusions (the structure after engagement is as follows). Figure 9 and Figure 11 As shown, when the hook rotates relative to the first side 310 around the second pivot axis until it abuts against the limiting part 32, the limiting part 32 will not wobble. Since the first bottom surface 312 is relatively fixed to the first side 310, the limiting part 32 and the first bottom surface 312 form an angle-limiting structure, which can limit the range of the angle at which the hook rotates relative to the first side 310 around the second pivot axis. Therefore, the angle at which the hook rotates relative to the first side 310 around the second pivot axis can be limited by the included angle between the limiting part 32 and the first bottom surface 312. In some specific embodiments, the central axis of the second pivot axis is not parallel to the central line of the first pivot axis, so that the lamp has greater flexibility in angle adjustment when rotating relative to the hook around the first and second pivot axes.

[0084] In some further preferred embodiments, such as Figure 9 and Figure 11 As shown, the limiting part 32 is plate-shaped, and after the limiting part 32 is connected to the first bottom surface 312 by the engaging structure, the two form an "L"-shaped structure. Thus, the limiting part 32 and the first bottom surface 312 can restrict the hook body from rotating within a 90° range around the second pivot axis; moreover, the "L"-shaped profile structure can ensure the small and compact structure of the hook body connecting module, realizing the miniaturization and weight reduction of the structure.

[0085] In some preferred embodiments, such as Figure 12 As shown, the first side 310 includes a first side portion 311 and a second side portion 313. The first side portion 311 and the second side portion 313 are respectively fixedly disposed opposite to the two sides of the first bottom surface 312, so that the first side portion 311, the first bottom surface 312 and the second side portion 313 together form an approximately "U" shaped structure, so as to improve the stability of the hook body pivot connection when the hook body is pivotally connected to the first side portion 311 and the second side portion 313 respectively through the second pivot axis; and ensure the small and compact structure of the hook body connection module, realizing the miniaturization and weight reduction of the structure.

[0086] In some further preferred embodiments, such as Figure 10As shown, a first pivot hole 3111 is integrally formed or machined on the first side portion 311, and a second pivot hole 3131 is integrally formed or machined on the second side portion 313. The first pivot hole 3111 and the second pivot hole 3131 are opposite to each other and coaxially spaced, respectively penetrating the first side portion 311 and the second side portion 313. The central axes of the first pivot hole 311 and the second pivot hole 3131 are parallel to the central axis of the second pivot axis, so that the hook body can rotate relative to the first side portion 311 and the second side portion 313 around the second pivot axis through the first pivot hole 3111 and the second pivot hole 3131 respectively (the second connecting bolt passes through the second pivot hole 3111 and the second pivot hole 3131). Preferably, the center of the first pivot hole 3111 and the second pivot hole 3131 is connected so that the projection of the first bottom surface 312 passes through the center of the second mounting hole 3122.

[0087] In some further preferred embodiments, such as Figure 12 As shown, the limiting part 32 is integrally formed or machined with a second protrusion 322 and a third protrusion 323. The first side part 311 is integrally formed or machined with a first groove 3112 that matches the second protrusion 322. The second side part 313 is integrally formed or machined with a second groove 3132 that matches the third protrusion 323. This allows the limiting part 32 to engage with the first side part 311 and the second side part 313 when the second protrusion 322 engages in the first groove 3112 and the third protrusion 323 engages in the second groove 3132. (The structure after connection is as follows) Figure 9 and Figure 11 As shown in the diagram, the limiting part 32 connected to the first side 311 and the second side 313 can withstand the resistance force of the hook body without shaking, and the limiting part 32 can improve the stability of the first side 311 and the second side 313; especially when the limiting part 32 is also engaged with the first mounting hole 3121 of the first bottom surface 312 through the first protrusion 321, the limiting part 32 is engaged with the first bottom surface 312, the first side 311 and the second side 313 through the three protrusions respectively, which further improves the stability of the engagement connection between the limiting part 32 and the first bottom surface 312, the first side 311 and the second side 313, and improves the stability of the limiting part 32 supporting the rotating hook body. Preferably, the first slot 3112 and the second slot 3132 are arranged opposite to each other. Preferably, the projections of the first slot 3112, the first mounting hole 3121, and the second slot 3132 onto the first bottom surface 312 are on the same straight line, so that after the limiting part 32 is connected to the first bottom surface 312 engaging structure, an "L"-shaped structure is formed between them. Preferably, as shown... Figure 12 As shown, the second protrusion 321 and the third protrusion 323 are located on the upper surface of the second body 320 and are arranged symmetrically.

[0088] In some further preferred embodiments, such as Figure 12As shown, the first slot 3112 and the second slot 3132 are respectively disposed at the ends of the first side portion 311 and the second side portion 313 that are opposite to the first bottom surface 312 (that is, the first slot 3112 and the second slot 3132 are respectively disposed at the top of the first side portion 311 and the second side portion 313, i.e., the upper end surface). Thus, by placing the limiting part 32 on the first side portion 311 and the second side portion 313, a quick engaging connection between the limiting part 32 and the first side portion 311 and the second side portion 313 can be achieved.

[0089] In some further preferred embodiments, such as Figure 9 As shown, after the limiting part 32 engages with the first side part 311 and the second side part 313, the first side part, the limiting part and the second side part form a "U" shaped structure to ensure the small and compact structure of the hook body connecting module, and to achieve the miniaturization and weight reduction of the structure.

[0090] In some preferred embodiments, such as Figure 9 and Figure 10 As shown, at least one of the upper and lower surfaces of the first bottom surface 312 remains flat.

[0091] In some preferred embodiments, such as Figure 9 and Figure 10 As shown, the first side portion 311 and the second side portion 313 are parallel to each other and spaced apart.

[0092] In some specific embodiments, such as Figures 9 to 12 As shown, the first connecting bolt 33 passes through the second mounting hole 3122 on the first bottom surface 312 of the hook body connecting hanger 31 and then pivots the hook body connecting hanger 31 and the lamp connecting hanger 35 around the first pivot axis. The central axis of the first connecting bolt 33 is set parallel to the first pivot axis.

[0093] In some preferred embodiments, such as Figures 9 to 12 As shown, the lamp connecting pendant 35 is a flat structure used to support objects such as chandeliers. For example, the lamp connecting pendant 35 can be an independent support plate, which is indirectly fixed to the base surface of the chandelier. Of course, it can also be a combination of the lamp connecting pendant 31 and the limiting part 32, with bolts directly used as the lamp connecting pendant.

[0094] In some preferred embodiments, such as Figures 10 to 12As shown, the lamp connecting pendant 35 includes a first pendant body 351, a first boss 352 extending along one side of the first pendant body 351, and a second boss 353 stretched in the opposite direction on the first boss. The first boss 352 is a platform with a certain height above the upper plane of the first pendant body 351, formed by stretching or machining. Its shape can be a frustum or other shapes, such as a frustum of a cone or a truncated pyramid. In this embodiment, it is a frustum. The second boss 353 is formed by stretching or extending in the opposite direction (e.g., integral molding or machining) from the center of the first boss 352. The inner holes of the first boss 352 and / or the second boss 353 are threaded (forming a first threaded hole, not shown) so that the lamp connecting pendant 35 can be used as a nut without significantly increasing the weight of the lamp connecting pendant 35. Preferably, the first boss 352 is located in the middle of the first pendant body 351.

[0095] In some preferred embodiments, such as Figure 10 and Figure 12 As shown, the first hanging component body 351 also has integrally formed or machined mounting holes for connecting with the lamp. The mounting holes include a first mounting hole 354 and a second mounting hole 355, which penetrate through the first hanging component body 351. Preferably, the first mounting hole 354 and the second mounting hole 355 are located on both sides of the first boss 352 and are symmetrically arranged. When the connection size L of the lamp base has multiple specifications, the lamp connecting hanging component 35 and the hook connecting module can be rotated relative to each other around the first pivot axis to the mounting hole position of the lamp base. This allows a lamp connecting hanging component 35 of one specification to be adapted to lamp bases of multiple connection sizes L without changing the orientation of the multiple hooks on the lamp base, thereby improving the versatility of the hanging component connecting module.

[0096] In some preferred embodiments, such as Figures 9 to 12As shown, the first elastic element is an elastic washer 34. The first connecting bolt 33 is passed sequentially through the second mounting hole 3122 on the first bottom surface 312 of the hook body connecting hanger 31 and the inner hole of the elastic washer 34, and then screwed into the threads of the first boss 352 and the second boss 353. Then, the free end (the end away from the bolt head) of the first connecting bolt 33 and the lower end of the second boss 353 can be welded or riveted to prevent the first connecting bolt 33 from falling out of the threaded hole on the lamp connecting hanger 35. Alternatively, a lock nut can be connected to the free end of the first connecting bolt 33 to prevent the first connecting bolt 33 from loosening. The welding structure, riveting structure, or lock nut connected to the free end of the first connecting bolt 33 and the lamp connecting hanger 35 is an anti-loosening structure for preventing the first connecting bolt 33 from falling out of the lamp connecting hanger 35 according to an embodiment of this application. Thus, the hook body connecting module, the elastic washer 34, and the lamp connecting hanger 35 can be connected as a whole by the first connecting bolt 33, preventing the hook body connecting module, the first elastic element 33, and the lamp connecting hanger 35 from falling off after connection. Since the hook connecting module and the lamp connecting hanger 35 are pivotally connected by the first connecting bolt 33, the connection efficiency can be improved.

[0097] In some further preferred embodiments, the concave surface of the elastic washer 34 faces the lamp connecting hanger 35, and the convex surface of the elastic washer 43 faces away from the lamp connecting hanger 35. When the lamp connecting hanger 35 and the hook connecting module are pivotally connected by the first connecting bolt 33, the elastic washer 34 is clamped between them. Thus, the tension generated by the deformation of the elastic washer 34 tightly fixes the hook connecting hanger 31 to the first boss 352 on the lamp connecting hanger 35. Only under the action of a large external force can the combination of the hook connecting hanger 31 and the limiting part 32 rotate 360 ​​degrees around the axis of the first connecting bolt 33. If no large torque is applied to the hook connecting module and the lamp connecting hanger 35, the hook connecting module will not rotate relative to the lamp connecting hanger 35, so as to ensure the stability of their relative positions and the structural stability of the hanger connecting module.

[0098] Example 2

[0099] Figures 13 to 15A second embodiment of the pendant connection module of this application is shown as an example. The difference between the pendant connection module of this embodiment and the first embodiment is that, based on the first embodiment, at least one reinforcing plate 356 is integrally formed, processed, or connected to the first pendant body 351 of the lamp connecting pendant 35. The reinforcing plate 356 is disposed on the side of the limiting part 32 opposite to the first side 310. Thus, the reinforcing plate 356 can provide support for the limiting part 32 and / or the first side 310, improving the stability of the limiting part 32 as an angle-limiting structure. Preferably, the reinforcing plate 356 abuts against at least one of the first side 310, the first bottom surface 312, and the limiting part 32, and the reinforcing plate 356 is located on the side opposite to the opening formed between the first bottom surface 312 and the limiting part 32. Further preferably, two reinforcing plates 356 are provided, with a notch formed on the side of the limiting part 32 opposite to the hook connecting module, or a clearance part 3133 is provided on at least one of the first side 310, the first bottom surface 312, and the limiting part 32. The clearance part is, for example, a chamfer or rounded corner, thereby ensuring that the hook connecting module can rotate 360° relative to the lamp connecting hanger 35 around the first pivot axis. This prevents the reinforcing plate 356 from obstructing the rotation of the hook connecting module when the hook connecting module and the lamp connecting hanger 35 rotate relative to each other around the first pivot axis. Preferably, the reinforcing plate 356 is vertically disposed on one side of the long side of the first hanger body 351, and is formed by bending the first hanger body 351, symmetrically arranged on both sides of the first boss 352. This serves to increase the hanging weight.

[0100] Example 3

[0101] Figures 16 to 17 The third embodiment of the hanging component connection module of this application is shown as an example. This embodiment is basically the same as the second and third embodiments, except that: the lamp connecting hanging component 35 of the hanging component connection module of this embodiment is a first nut and the first elastic component 34 is a flat spring washer. The hanging component connection module of this embodiment is mainly used for hanging folding lamp hooks of PAR lamps, or is suitable for lamps with only one connection hole.

[0102] Example 4

[0103] Figure 18 and Figure 19A first embodiment of the lifting component connection module of this application is shown as an example. This lifting component connection module is based on the first embodiment and further includes a hook body adapter lifting component 62. The hook body adapter lifting component 62 is used to pivotally connect the hook body connection module and the hook body about a second pivot axis and / or a third pivot axis; wherein the third pivot axis is arranged parallel to the first pivot axis, so that when the hook body is connected to the hook body connection module through the hook body adapter lifting component 62, the hook body can rotate relative to the hook body connection module about the second pivot axis and the third pivot axis, thereby improving the flexibility of hook body adjustment.

[0104] In some preferred embodiments, such as Figure 18 and Figure 19 As shown, the hook body adapter 62 includes a second side 620 for pivotally connecting to the hook body connection module about a second pivot axis; and a second bottom surface 622 for pivotally connecting to the hook body about a third pivot axis. Thus, the hook body can rotate relative to the lamp connection pendant 35 of the pendant connection module about the first, second, and third pivot axes.

[0105] In some preferred embodiments, such as Figure 19 As shown, the second side 620 includes a third side 621 and a fourth side 623. The third side 621 and the fourth side 623 are respectively fixedly disposed opposite to the two opposite sides of the second bottom surface 622. For example, the third side 621 and the fourth side 623 are integrally formed with the second bottom surface 622 by molding or bending sheet metal, so that the hook body adapter lifter forms an approximately "U" shaped structure. Thus, the hook body can be pivotally connected to the third side 621 and the fourth side 623 respectively through the second pivot axis, thereby improving the stability of the hook body pivot connection; moreover, the "U" shaped profile structure can ensure the small and compact structure of the hook body adapter lifter, realizing the miniaturization and lightweight of the structure.

[0106] In some preferred embodiments, reference Figure 18 and Figure 19As shown, the lifting component connection module also includes a second connecting bolt 61 and a second nut 65. The third pivot hole 6211 is integrally formed or machined on the third side portion 621, preferably machined at the center of the semicircle of the third side portion 621; the fourth pivot hole 6231 is integrally formed or machined on the fourth side portion 623, preferably machined at the center of the semicircle of the fourth side portion 623; the third pivot hole 6211 and the fourth pivot hole 6231 are opposite to each other and coaxially arranged, and respectively penetrate the third side portion 621 and the fourth side portion 623. The second connecting bolt 61 passes sequentially through the first pivot hole 3111 on the first side 311, the third pivot hole 6211 on the third side 621, the fourth pivot hole 6231 on the fourth side 623, and the second pivot hole 3131 on the second side 313. Then, the second connecting bolt 61 is threadedly connected to the second nut 65, allowing the hook body adapter 62 to pivotally connect to the hook body connecting module around the second pivot axis via the second connecting bolt 61. The central axis of the second connecting bolt 61 is parallel to the central axis of the second pivot axis. This enables a quick and detachable connection between the hook body adapter 62 and the hook body connecting module. Because the first bottom surface 312 and the blocking part 32 form an angle-limiting structure, the hook body adapter 62 can rotate 90° relative to the hook body connecting module around the second pivot axis. Preferably, the second nut 65 is a lock nut.

[0107] In some preferred embodiments, such as Figure 18 and Figure 19 As shown, the lifting component connection module also includes a third connecting bolt 63 and a third nut 64. The connecting hole 6221 is integrally formed or machined on the second bottom surface 622. The third connecting bolt 63 is a press-fit screw. After the third connecting bolt 63 passes through the connecting hole 6221, the two are press-fitted together with a riveting machine and then surface-treated. After the nut 64 is installed, an assembly is formed, so that the hook body connected to the hook body adapter 62 through the third connecting bolt 63 can be pivotally connected to the hook body adapter 62 around the third pivot axis through the third connecting bolt 63. The central axis of the third connecting bolt 63 is parallel to the central axis of the third pivot axis. The third pivot axis is parallel to the first pivot axis. Therefore, when the hook body can rotate relative to the lamp connecting member 35 of the connecting module around the first, second, and third pivot axes, the position of the hook body relative to the lamp connecting member 35 in three-dimensional space can be adjusted, improving the flexibility of hook body adjustment. Furthermore, the hook body connecting module, lamp connecting member 35, and hook body adapter 62 can be surface-treated before assembly to avoid the problem of incomplete surface treatment after assembly, which can lead to easy rusting. In some preferred embodiments, the third nut 64 is a lock nut.

[0108] In some preferred embodiments, such as Figure 18 and Figure 19 As shown, at least one of the upper and lower surfaces of the second bottom surface 622 remains flat.

[0109] In some preferred embodiments, such as Figure 18 and Figure 19 As shown, the third side portion 621 and the fourth side portion 623 are parallel to each other and spaced apart.

[0110] In some preferred embodiments, such as Figure 18 and Figure 19 As shown, the connecting hole 6221 is located in the middle of the second bottom surface 622. Preferably, the centers of the third pivot hole 6211 and the fourth pivot hole 6231 are connected so that the projection of the second bottom surface 622 passes through the center of the connecting hole 6221.

[0111] Example 5

[0112] This embodiment is a second embodiment of the hanging component connection module of this application. The hanging component connection module of this embodiment is based on the hanging component connection module of the first embodiment, but the specific implementation of the lamp connecting hanging component 35 is changed. The lamp connecting hanging component 35 in this embodiment adopts the lamp connecting hanging component 35 of embodiment two. That is, at least one reinforcing plate 356 is integrally formed, processed or connected to the first hanging component body 351 of the lamp connecting hanging component 35.

[0113] Example 6

[0114] This embodiment is the third embodiment of the lifting component connection module of this application. The lifting component connection module of this embodiment is based on the lifting component connection module of the first embodiment, and an anti-loosening spring 66 is added. The anti-loosening spring 66 is fitted on the second connecting bolt 61, and its two ends abut against the third side 621 and the fourth side 623 respectively.

[0115] The anti-loosening spring 66 is the second elastic element in one embodiment of this application. The anti-loosening spring 66 may be, for example, a compression spring.

[0116] Example 7

[0117] Figure 20 The fourth embodiment of the lifting component connection module of this application is shown by way of example. The lifting component connection module of this embodiment is based on the lifting component connection module of the second embodiment, with the addition of an anti-loosening spring 66. The anti-loosening spring 66 is fitted on the second connecting bolt 61, and its two ends abut against the third side 621 and the fourth side 623 respectively.

[0118] The anti-loosening spring 66 is the second elastic element in one embodiment of this application. The anti-loosening spring 66 can be, for example, a compression spring. Under the elastic action of the anti-loosening spring 66, there is a preload between the third side 621 and the fourth side 623 and the first side 311 and the second side 313. When no large torque is applied to the first side 311, the second side 313, the third side 621, and the fourth side 623, the first side 311, the second side 313, the third side 621, and the fourth side 623 remain relatively stationary to ensure the stability of the relative position between the hook body adapter 62 and the hook body connection module.

[0119] Example 8

[0120] This embodiment is the fifth embodiment of the hanging component connection module of this application. The hanging component connection module of this embodiment is based on the hanging component connection module of the first embodiment, but with a change in the specific implementation of the lamp connecting hanging component 35. The lamp connecting hanging component 35 in this embodiment adopts the lamp connecting hanging component 35 of Embodiment 3. The lamp connecting hanging component 35 is the first nut.

[0121] Example 9

[0122] Figure 21 The sixth embodiment of the lifting component connection module of this application is shown by way of example. The lifting component connection module of this embodiment is based on the lifting component connection module of the fifth embodiment, with the addition of an anti-loosening spring 66. The anti-loosening spring 66 is fitted on the second connecting bolt 61, and its two ends abut against the third side 621 and the fourth side 623 respectively.

[0123] Example 10

[0124] Figure 22 One of the fourth embodiments of the lifting component connection module of this application is shown as an example.

[0125] The difference between this embodiment and the first embodiment of the hanging component connection module is that there are two hook-connecting hanging components 31, two limiting parts 32, two elastic washers 34 and two first connecting bolts 33, and the size of the lamp connecting hanging component 35 is relatively large.

[0126] The hook connecting lifting member 31 and the limiting part 32 are the same as those in the first embodiment of the lifting member connecting module, and will not be described again.

[0127] The lamp connecting pendant 35 is an integrated assembly structure, including a first pendant body 351, two first bosses 352 distributed at both ends, and second bosses stretched in opposite directions on the first bosses. The specific implementation of the first bosses 352 and the second bosses is the same as that of the first embodiment of the pendant connecting module, except that there are two of each of the first bosses 352 and the second bosses, and they are distributed on both sides of the lamp connecting pendant 35, which will not be described in detail here.

[0128] The lamp connecting pendant 35 is also provided with multiple sets of mounting holes (including the first mounting hole 354 and the second mounting hole 355) that penetrate through the first pendant body 351, so as to facilitate connection with lamps of different installation sizes.

[0129] The installation method of the combination of the two hook-connecting hanger 31 and the limiting part 32 and the lamp connecting hanger 35 is the same as the installation method of the first embodiment of the hanger connecting module, except that there are two of them. After assembly, the combination of the hook-connecting hanger 31 and the limiting part 32 can rotate along their respective first connecting bolts 33 under the action of external force, which will not be described in detail.

[0130] Example 11

[0131] Figure 23 The second fourth embodiment of the lifting component connection module of this application is shown as an example.

[0132] The difference between this embodiment and one of the fourth embodiments of the hanging component connection module is that the hanging component connection module of this embodiment is used for larger lamps. The lamp connecting hanging component also includes two reinforcing plates 356, which are vertically arranged on the long side of the body 351 and parallel to the line connecting the center lines of the two first protrusions 352.

[0133] Example 12

[0134] Figure 24 The third of the fourth embodiments of the lifting component connection module of this application is shown as an example.

[0135] The difference between this embodiment and one of the fourth embodiments of the pendant connection module is that the lamp connection pendant 35 is a special case of this utility model. It is no longer a solid connection plate, but is replaced by the base of the lamp itself.

[0136] Example 13

[0137] This embodiment is the fifth embodiment of the hanging component connection module of this application. The difference between this embodiment and the first to third embodiments of the hanging component connection module is that the lamp connecting hanging component is neither a plate structure nor a nut, but a first connecting bolt that passes through the second mounting hole on the first bottom surface. After the first connecting bolt passes through the second mounting hole, its free end is prevented from falling out of the second mounting hole on the first bottom surface by welding or riveting.

[0138] In this invention, the connection or installation is a fixed connection unless otherwise specified. A fixed connection can be implemented as a detachable or non-detachable connection commonly used in the prior art. A detachable connection can be implemented using existing technologies, such as threaded connections or keyed connections. A non-detachable connection can also be implemented using existing technologies, such as welding or adhesive bonding.

[0139] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
