Description

Technical Field

[0001] This utility model relates to the field of lighting safety equipment, and in particular to a hanging connection 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 connecting module that can connect the lamp hook to the fixture, and the lamp hook can be folded and set on the connecting 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 connecting module 10 is pivotally connected to 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 connection module 10 in the prior art is shown. Figure 3 An exploded perspective view of a connection module 10 in the prior art is shown. For example... Figure 2 As shown, the connecting 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 chandelier and control its light output direction, the assembly method between the folding hook and the chandelier base is usually divided into a split assembly structure or an integrated assembly structure, depending on the number and relative position of the folding hook and the connecting module.

[0010] The so-called modular assembly structure consists of two connecting modules 10. Folding hooks 18 and 19 are movably assembled with one of the connecting modules 10 and then fixed to the chandelier base 15. Simultaneously, the two connecting modules 10 are spaced apart on the surface of the chandelier base 15 and are independent of each other, as shown below. 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 connecting module 20 is an 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 connecting 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 are machined on the fixing plate 271. Mounting holes 2731 are machined on the fixing plate 2731. The mounting holes 2711 and 2731 are used for fixing to the lighting fixture housing.

[0012] However, the above structure still has the following drawbacks:

[0013] Defect 1: The connection module 10 has many different connection sizes L with the lamp base 15, so its fixing plate has to be made in many different ways, resulting in poor versatility.

[0014] Defect 2: 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.

[0015] Defect 3: Connecting modules 10 and 20. Since the parts are interlocking structures, they are welded and then surface treated as a whole. However, the joints of the interlocking structures cannot be properly treated, which can easily lead to rust and affect the appearance of the product.

[0016] Therefore, it is necessary to provide a new connection module to solve the aforementioned technical problems of poor versatility and unsuitability for mass production. Utility Model Content

[0017] The purpose of this utility model is to solve at least one of the above problems. This application provides a hanging connection module.

[0018] A hanging connection module includes a hook and a connection module. The connection module includes a bottom surface, a side surface, and a limiting part. The bottom surface is used to rotatably connect with a lamp connector or a lamp about a first pivot. The side surface is fixed relative to the bottom surface. The limiting part is detachably connected to at least one of the side surface and the bottom surface. The hook includes a hook body and a flip connector. The hook body is used to hang on a lamp mounting bracket. The flip connector is used to rotatably connect with the side surface about a second pivot. The limiting part is used to limit the flip angle of the hook.

[0019] Since the limiting part is detachably connected to at least one of the side and bottom surfaces, welding is not required, avoiding the problem of rust at the welded joints. This improves production efficiency, product lifespan, and aesthetics. The limiting part and bottom surface work together to limit the angle of hook flipping. In addition, the side and bottom surfaces are relatively fixed, and the side can be integrally formed with the bottom surface by molding or bending sheet metal parts. This reduces labor intensity, improves production efficiency, and ensures connection strength.

[0020] In some embodiments, the limiting portion and the bottom surface form an angle limiting structure, which can limit the range of the rotation angle of the hook body about the second axis.

[0021] In some embodiments, the side includes a first side and a second side, which are respectively fixedly disposed on both sides of the base so that the first side, the bottom surface and the second side together form a "U" shaped structure.

[0022] In some embodiments, the limiting part is detachably connected to the bottom surface by means of a snap-fit ​​structure, so that the limiting part and the bottom surface form an "L" shaped structure.

[0023] In some embodiments, the detachable connection between the limiting part and the side is achieved by the limiting part and at least one of the first side and the second side of the side being connected by an engaging structure, so that the first side, the limiting part and the second side form a "U" shaped structure.

[0024] In some embodiments, the lamp connector is provided with mounting holes for connecting to a lamp.

[0025] In some embodiments, a reinforcing plate is provided on the side of the lamp connector facing the connecting module.

[0026] In some embodiments, the hook body includes a first hook body, a second hook body, and a quick-release rod assembly. The flip connector is disposed on the first hook body. The first hook body and the second hook body are hinged to each other. The other end of the first hook body is hinged to the quick-release rod assembly. The other end of the second hook body is inserted into the quick-release rod assembly, so that the first hook body, the second hook body, and the quick-release rod assembly surround and form a clamping cavity.

[0027] In some embodiments, the hook body includes a fixed hook body, a movable hook body, and a drive assembly. The flip connector is disposed on the fixed hook body. One end of the movable hook body is hinged to the fixed hook body, and the other end is closed with the fixed hook body under the push of the drive assembly to form a clamping cavity.

[0028] In some embodiments, the hook body includes a fixed hook body, a movable hook body, and a drive assembly. The flip connector is disposed on the fixed hook body. One end of the movable hook body is hinged to the fixed hook body, and the other end forms a "C"-shaped clamping cavity with the fixed hook body under the push of the drive assembly.

[0062] The accompanying drawings illustrate a hanging connection module of this utility model.

[0063] Example 1

[0064] Figures 5 to 6 An exemplary embodiment of the connection module of this application is shown.

[0065] like Figure 6 As shown, the connecting module includes a limiting part 32. The connecting module also includes a hook connector 31, which includes a bottom surface 312. The bottom surface 312 has an integrally formed (e.g., formed by die stamping or bending of sheet metal) or machined side edge 310. The bottom surface 312 has an integrally formed or machined first mounting hole 3121 and a second mounting hole 3122. The side edge 310 has an integrally formed or machined slot. The limiting part 32 includes a second body 320, which has integrally formed or machined protrusions that engage with the first mounting hole 3121 and the slot, respectively. The protrusion engaging with the first mounting hole 3121 is the first protrusion 321. The second mounting hole 3122 is a mounting hole for rotatably connecting the bottom surface 312 to the lamp connector 35 or the lamp around a first pivot.

[0066] Since the limiting part 32 is detachably connected to the side 310 and the bottom surface 312 by a snap-fit ​​connection, the assembly process is not only labor-saving and quick, but also does not require welding. Therefore, it is not easy for rust to form at the weld, thereby improving production efficiency, product lifespan and product aesthetics. Moreover, the side 310 and bottom surface 312 are made into one piece by molding or bending sheet metal parts, which can ensure the connection strength. Furthermore, the limiting part 32, bottom surface 312 and first side surface 310 can be surface treated before assembly to avoid the problem of easy rust caused by incomplete surface treatment after assembly.

[0067] In some preferred embodiments, such as Figure 6 As shown, the first mounting hole 3121 is non-circular to restrict the rotation of the limiting part 32, which is engaged in the first mounting hole 3121 through the first protrusion 321, relative to the bottom surface 312.

[0068] In some preferred embodiments, such as Figure 6 As shown, the first protrusion 321 is located at the center of the lower end face of the second body 320.

[0069] In some preferred embodiments, such as Figure 6 As shown, the second mounting hole 3122 is a through hole that penetrates the bottom surface 312 so that the bottom surface 312 can be rotated relative to the lamp connector 35 around the first rotating shaft through the second mounting hole 3122 (through which the connecting bolt passes).

[0070] In some preferred embodiments, such as Figure 5 As shown, the end of the limiting part 32 that is engaged with the side 310 that is opposite to the bottom surface 312 is flush with the end of the side 310 that is opposite to the bottom surface 312. This ensures the compactness of the structure connecting the limiting part 32 and the side 310.

[0071] In some preferred embodiments, reference continues to be made to Figure 6 As shown, the side 310 is configured to allow a hook (e.g., a folding hook 18) attached thereto to rotate relative to the side 310 about a second pivot. The limiting part 32 engages with the first mounting hole 3121 of the bottom surface 312 via the first protrusion 321, and with the slots of the side 310 via other protrusions (the structure after engagement is as follows). Figure 5 As shown, when the hook rotates around the second pivot relative to the side 310 until it abuts against the limiting part 32, the limiting part 32 will not wobble. Since the bottom surface 312 is relatively fixed to the side 310, the limiting part 32 and the bottom surface 312 form an angle-limiting structure, which can limit the range of the angle at which the hook rotates around the second pivot relative to the side 310. Therefore, the angle at which the hook rotates around the second pivot relative to the side 310 can be limited by the included angle between the limiting part 32 and the bottom surface 312. In some specific embodiments, the central axis of the second pivot is not parallel to the center line of the first pivot, so that the lamp has greater flexibility in angle adjustment when rotating relative to the hook around the first and second pivots.

[0072] In some further preferred embodiments, such as Figure 6 As 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 rotating shaft, so that the hook body can rotate around the second rotating shaft relative to the first side portion 311 and the second side portion 313 through the first pivot hole 3111 and the second pivot hole 3131 respectively (through which the second connecting bolt passes). Preferably, the projection of the center of the first pivot hole 3111 and the second pivot hole 3131 onto the bottom surface 312 passes through the center of the second mounting hole 3122.

[0073] In some further preferred embodiments, such as Figure 5 and Figure 6 As shown, the limiting part 32 is plate-shaped, and after the limiting part 32 and the bottom surface 312 are connected by a snap-fit ​​structure, an "L"-shaped structure is formed between them. Thus, the limiting part 32 and the bottom surface 312 can restrict the hook body from rotating within a 90° range around the second pivot; moreover, the "L"-shaped profile structure can ensure the compactness of the connecting module structure, realizing the miniaturization and weight reduction of the structure.

[0074] In some further preferred embodiments, such as Figure 5 and Figure 6As shown, the 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 arranged opposite to the two sides of the bottom surface 312, so that the first side portion 311, the bottom surface 312 and the second side portion 313 together form a "U" shaped structure, which improves the stability of the hook body rotation connection when the hook body is rotatably connected to the first side portion 311 and the second side portion 313 through the second rotating shaft; and ensures that the structure of the connection module is small and compact, realizing the miniaturization and weight reduction of the structure.

[0075] In some further preferred embodiments, such as Figure 6 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 5 As shown), the limiting part 32 connected to the first side 311 and the second side 313 can withstand the resistance 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 bottom surface 312 through the first protrusion 321, the limiting part 32 is engaged with the 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 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 bottom surface 312 are on the same straight line, so that after the limiting part 32 is connected to the bottom surface 312 engaging structure, an "L"-shaped structure is formed between them. Preferably, as... Figure 6 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.

[0076] In some further preferred embodiments, such as Figure 6As 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 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.

[0077] In some further preferred embodiments, such as Figure 5 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 that the structure of the connecting module is small and compact, and to achieve miniaturization and weight reduction of the structure.

[0078] In some preferred embodiments, such as Figure 5 and Figure 6 As shown, at least one of the upper and lower surfaces of the bottom surface 312 remains flat.

[0079] In some preferred embodiments, such as Figure 5 and Figure 6 As shown, the first side portion 311 and the second side portion 313 are parallel to each other and spaced apart.

[0080] Example 2

[0081] Figures 7 to 10 A first embodiment of the connecting module 30 of this application is shown as an example. The connecting module 30 is a connector for connecting a hook body and a stage lighting fixture base. The connecting module 30 includes a hook body connector 31, a limiting part 32, a lighting fixture connector 35, and a connecting bolt 33. The lighting fixture connector 35 is used to connect to or be integrally formed with a lighting fixture. The connecting module is rotatably mounted on the lighting fixture connector about a first pivot axis.

[0082] In some specific embodiments, such as Figure 8 and Figure 9 As shown, after the connecting bolt 33 passes through the second mounting hole 3122 on the bottom surface 312 of the hook body connector 31, the hook body connector 31 and the lamp connector 35 are rotatably connected around the first rotating shaft. The central axis of the connecting bolt 33 is coaxial with the central axis of the first rotating shaft, or the first connecting bolt 33 is the first rotating shaft.

[0083] In some preferred embodiments, such as Figure 10 As shown, the hook connector 31 adopts the hook connector 31 in the first embodiment.

[0084] In some preferred embodiments, such as Figure 10As shown, the limiting part 32 adopts the limiting part 32 in the first embodiment.

[0085] In some preferred embodiments, such as Figure 7 As shown, the hook connector 31 and the limiting part 32 are integrally formed into the connection module in the first embodiment.

[0086] In some preferred embodiments, such as Figure 7 and Figure 10 As shown, the lamp connector 35 is a flat structure used to support objects such as chandeliers. For example, the lamp connector 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 connector 31 and the limiting part 32, which is directly fixed with bolts.

[0087] In some preferred embodiments, such as Figure 8 and Figure 9 As shown, the lamp connector 35 includes a first hanging body 351, a first boss 352 extending along one side of the first hanging 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 hanging 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 connector 35 can be used as a nut without significantly increasing the weight of the lamp connector 35. Preferably, the first boss 352 is located in the middle of the first hanging body 351.

[0088] In some preferred embodiments, such as Figure 8 and Figure 10 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 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 lamp base has multiple connection sizes L, the lamp connector 35 can be rotated relative to the connecting module around the first pivot to the mounting hole position of the lamp base. This allows a single size of lamp connector 35 to adapt 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 connecting module.

[0089] In some preferred embodiments, such as Figures 7 to 10As shown, the connecting module also includes a first elastic element, which is disposed between the connecting module and the lamp connector 35. Therefore, even when the connecting module and the lamp connector 35 are rotated around the first axis and the first elastic element is clamped, due to the elasticity of the first elastic element, when a large torque is applied to the connecting module or the lamp connector 35, the elastic deformation of the first elastic element allows the connecting module and the lamp connector 35 to rotate relative to each other around the first axis.

[0090] In some preferred embodiments, such as Figures 7 to 10 As shown, the first elastic element is an elastic washer 34. The connecting bolt 33 is passed sequentially through the second mounting hole 3122 on the bottom surface 312 of the hook body connector 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 of the connecting bolt 33 (the end away from the bolt head) and the lower end of the second boss 353 can be welded or riveted to prevent the connecting bolt 33 from falling out of the threaded hole on the lamp connector 35. Alternatively, a lock nut can be connected to the free end of the connecting bolt 33 to prevent the connecting bolt 33 from loosening. The welding structure, riveting structure, or lock nut connected to the free end of the connecting bolt 33 with the lamp connector 35 is an anti-loosening structure for preventing the connecting bolt 33 from falling out of the lamp connector 35 according to an embodiment of this application. This allows the connecting module, elastic washer 34, and lamp connector 35 to be connected as a single unit using the connecting bolt 33, preventing them from detaching after connection. The connecting module and lamp connector 35 are also rotatably connected using the connecting bolt 33, which improves connection efficiency.

[0091] In some further preferred embodiments, the concave surface of the elastic washer 34 faces the lamp connector 35, and the convex surface of the elastic washer 43 faces away from the lamp connector 35. When the lamp connector 35 and the connecting module are rotatably connected by the 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 connector 31 to the first boss 352 on the lamp connector 35. Only under the action of a large external force (such as manual tightening) can the combination of the hook connector 31 and the limiting part 32 rotate 360 ​​degrees around the axis of the connecting bolt 33. If no large torque is applied to the connecting module and the lamp connector 35, the connecting module will not rotate relative to the lamp connector 35, so as to ensure the stability of their relative positions and the structural stability of the connecting module.

[0092] Example 3

[0093] Figures 11 to 13A second embodiment of the connection module of this application is shown as an example. The difference between the connection module of this embodiment and the second embodiment is that, based on the second embodiment, the lamp connector 35 has at least one reinforcing plate 356 integrally formed, processed, or connected to the first hanging body 351 of the lamp connector 35. The reinforcing plate 356 is disposed on the side of the limiting part 32 opposite to the side 310. Thus, the reinforcing plate 356 can provide support for the limiting part 32 and / or the 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 side 310, the 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 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 connecting module, or a clearance part 3133 is provided on at least one of the side 310, bottom surface 312, and limiting part 32. The clearance part is, for example, a chamfer or rounded corner, thereby ensuring that the connecting module can rotate 360° relative to the lamp connector 35 around the first pivot axis. This prevents the reinforcing plate 356 from obstructing the rotation of the connecting module when the connecting module and the lamp connector 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 hanging body 351, bent from the first hanging body 351, and symmetrically arranged on both sides of the first boss 352. This serves to increase the hanging weight.
