Technical Field
[0001] This utility model application relates to the field of chandelier technology, specifically to an extendable chandelier connector. Background Technology
[0002] Chandelier connectors are key components used for electrical wiring connections. Through sealed design and high-quality materials such as copper alloy and gold plating, they ensure circuit stability and safety, effectively preventing short circuits and leakage in humid environments. Their core function is to provide a reliable transmission path for current or signals, and they are compatible with various interfaces such as threaded, pin-type, and bayonet-type connectors to meet the needs of home, commercial, and industrial scenarios.
[0003] Chinese patent CN220544412U discloses a chandelier connector and a chandelier thereof. The chandelier connector includes a connector body, a male connector that snaps into the connector body, and a female connector corresponding to the male connector. The female connector passes through the connector body and is inserted into the male connector to form an electrical connection. The chandelier includes a mounting base with several chandelier connectors inside. The mounting base has extension rods corresponding to the number of chandelier connectors on its exterior. The extension rods are fixed to the female connectors of their respective chandelier connectors. A lamp is mounted on the other end of each extension rod. The male connector snaps into the connector body for a secure connection. The female connectors are corresponding to the male connectors and are inserted to form an electrical connection, thereby transmitting current and signals. The chandelier connector is an interface for connecting the lamp and the power supply. The extension rods connect the female connectors of the chandelier connectors to the lamps and also support the entire chandelier in space, providing illumination to the surrounding area.
[0004] The chandelier connector in the aforementioned patent document connects the suspending base and the mounting base via a suspending chain, resulting in a non-adjustable distance between the suspending base and the mounting base, making it extremely inconvenient to use. Therefore, an extendable chandelier connector is proposed. Utility Model Content
[0005] To address the aforementioned issues, a extendable chandelier connector is provided, utilizing the rotation of a shaft to extend and retract the pull rope. When releasing the rope, the telescopic rod at one end of the rope descends along the central axis of the inner sleeve under its own weight, thus extending the telescopic rod. When the shaft retracts the pull rope, the shaft, through the pull rope, drives the telescopic rod upwards along the central axis of the inner sleeve, retracting the telescopic rod. This solves the problem of the chandelier connector's inability to extend.
[0006] To address the problems of the prior art, this application provides an extendable chandelier connector, including a hanging rod, a limiting mechanism disposed at the bottom end of the hanging rod, a telescopic mechanism disposed inside the limiting mechanism, a lamp post disposed at the bottom of the telescopic mechanism, a lighting lamp mounted on the lamp post, and an adjustment mechanism disposed on the hanging rod. The limiting mechanism includes an inner sleeve installed inside the hanging rod. The telescopic mechanism includes a telescopic rod that can move longitudinally along the inner sleeve, and a lifting lug is fixed to the top of the telescopic rod; The adjustment mechanism includes a fixed seat fixed to the outer wall of the boom near the top. The interior of the fixed seat is connected to the interior of the boom. A rotatable shaft is horizontally arranged on the fixed seat. A flexible pull rope is wound on the shaft. One end of the pull rope is fixedly connected to the lifting lug. The adjustment mechanism also includes a ratchet located on one side of the fixed base, which is fixed to one end of the rotating shaft; A first mounting post is fixed to one side of the fixed base, and a pawl capable of engaging with the ratchet is mounted on the first mounting post.
[0007] As one technical solution of this application, a second mounting post is also fixed on one side of the fixed base, and a tension spring is installed on the second mounting post. One end of the tension spring is movably connected to the end of the pawl away from the ratchet.
[0008] As one technical solution of this application, a protective cover is fixed on one side of the fixing base, and a clearance groove is provided on the protective cover; A lever that can extend out of the protective cover is fixed on the pawl.
[0009] As one technical solution of this application, the bottom of the inner sleeve is provided with an external threaded sleeve that can be fitted onto the outside of the boom; An internal threaded sleeve is rotatably mounted on the bottom of the boom to fix the external threaded sleeve, and the internal threaded sleeve and the external threaded sleeve are threadedly engaged.
[0010] As one technical solution of this application, a limiting groove is longitudinally formed on the inner wall of the inner sleeve; The telescopic rod is equipped with a limiting strip on its exterior that can slide and engage with the limiting groove.
[0011] As one technical solution of this application, the bottom end of the telescopic rod is fixed with a base for installing the lamp post, the end of the lamp post away from the base is fixed with a lamp holder, a lighting lamp is installed on the lamp holder, and the lighting lamp and the lamp holder are electrically connected.
[0012] The advantages of this utility model application compared to the prior art are: This application utilizes the rotation of a shaft to extend and retract the pull rope. When releasing the rope, the telescopic rod at one end of the rope descends along the central axis of the inner sleeve under its own weight, thus extending the telescopic rod. When the shaft retracts the pull rope, the shaft drives the telescopic rod upwards along the central axis of the inner sleeve via the pull rope, thus retracting the telescopic rod. This solves the problem of the chandelier connector's inability to extend. Attached Figure Description

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.
[0024] See Figures 1-9 As shown, an extendable chandelier connector includes a hanging rod 1, a limiting mechanism 2 disposed at the bottom end of the hanging rod 1, a telescopic mechanism 3 disposed inside the limiting mechanism 2, a lamp post 4 disposed at the bottom of the telescopic mechanism 3, a lighting lamp 5 mounted on the lamp post 4, and an adjustment mechanism 6 disposed on the hanging rod 1. The limiting mechanism 2 includes an inner sleeve 21 installed inside the hanging rod 1. The telescopic mechanism 3 includes a telescopic rod 31 that can move longitudinally along the inner sleeve 21, and a lifting lug 311 is fixed at the top of the telescopic rod 31. The adjustment mechanism 6 includes a fixed seat 61 fixed on the outer wall of the boom 1 near the top. The interior of the fixed seat 61 is connected to the interior of the boom 1. A rotatable shaft 62 is horizontally arranged on the fixed seat 61. A flexible pull rope is wound on the shaft 62. One end of the pull rope is fixedly connected to the lug 311. The adjustment mechanism 6 also includes a ratchet 622 disposed on one side of the fixed base 61, and the ratchet 622 is fixed to one end of the rotating shaft 62; A first mounting post 611 is fixed to one side of the fixed base 61, and a pawl 63 capable of engaging with the ratchet 622 is mounted on the first mounting post 611.
[0025] When the shaft 62 rotates, it retracts and extends the pull rope. During release, the telescopic rod 31 at one end of the pull rope descends along the central axis of the inner sleeve 21 under its own weight, thus extending the telescopic rod 31. When the shaft 62 retracts the pull rope, it drives the telescopic rod 31 upwards along the central axis of the inner sleeve 21, thus retracting the telescopic rod 31. This solves the problem of the chandelier connector's inability to extend. To prevent the shaft 62 from rotating backwards, a ratchet 622 is installed on one side of the fixing seat 61, and then the ratchet 622 is fixed to one end of the shaft 62. A pawl 63 is then installed on the first mounting post 611, allowing the pawl 63 to engage with the ratchet 622 to limit the rotation of the shaft 62, effectively preventing it from rotating backwards.
[0026] See Figure 9 As shown, a second mounting post 612 is also fixed on one side of the fixed base 61. A tension spring 64 is installed on the second mounting post 612. One end of the tension spring 64 is movably connected to the end of the pawl 63 away from the ratchet 622.
[0027] When the ratchet 622 rotates, it pushes the pawl 63 to rotate around the first mounting post 611. At this time, the pawl 63 pulls the tension spring 64, causing the tension spring 64 to accumulate potential energy. When the thrust on the rotating shaft 62 disappears or weakens, the potential energy accumulated in the tension spring 64 is released, causing the tension spring 64 to pull the pawl 63 back to its original position. Thus, the pawl 63 effectively limits the ratchet 622.
[0028] See Figure 9 As shown, a protective cover 65 is fixed to one side of the fixed base 61, and a clearance groove 651 is provided on the protective cover 65. A lever 631 that can extend out of the protective cover 65 is fixed on the pawl 63.
[0029] To enable the rotating shaft 62 to effectively retract the pull rope, the lever 631 is moved along the relief groove 651, causing the lever 631 to drive the pawl 63 to rotate around the first mounting post 611, thus separating the pawl 63 from the ratchet 622. This allows the rotating shaft 62 to rotate while simultaneously winding up the pull rope.
[0030] See Figure 5 and Figure 7 As shown, the bottom of the inner sleeve 21 is provided with an external threaded sleeve 23 that can be fitted onto the outside of the rod 1; An internal threaded sleeve 11 is rotatably mounted on the bottom end of the boom 1, which can fix the external threaded sleeve 23. The internal threaded sleeve 11 and the external threaded sleeve 23 are threadedly engaged.
[0031] To ensure the stability of the limiting mechanism 2, a rotatable internal threaded sleeve 11 is installed at the bottom end of the lifting rod 1. When the internal threaded sleeve 11 rotates, it engages with the external threaded sleeve 23 and is axially pressed when rotating clockwise. This achieves the fixation of the internal threaded sleeve 11 on the external threaded sleeve 23.
[0032] See Figure 5 and Figure 7 As shown, a limiting groove 22 is longitudinally formed on the inner wall of the inner sleeve 21; The telescopic rod 31 is provided with a limiting strip 312 on its outside, which can slide and cooperate with the limiting groove 22.
[0033] To prevent the telescopic rod 31 from rotating axially, a limiting strip 312 is set longitudinally on the outside of the telescopic rod 31. When the telescopic rod 31 moves longitudinally, the telescopic rod 31 drives the limiting strip 312 to slide along the limiting groove 22, so that the limiting groove 22 and the limiting strip 312 cooperate to limit the telescopic rod 31, effectively preventing the telescopic rod 31 from rotating axially.
[0034] See Figure 1 , Figure 2 and Figure 3 As shown, the bottom end of the telescopic pole 31 is fixed with a base 313 for mounting the lamp pole 4, and the end of the lamp pole 4 away from the base 313 is fixed with a lamp holder 41. A lighting lamp 5 is mounted on the lamp holder 41, and the lighting lamp 5 and the lamp holder 41 are electrically connected.
[0035] The lamp post 4 is equidistantly distributed around the central axis of the telescopic rod 31 and fixed to the base 313 with bolts. Then, the lighting lamp 5 is installed on the lamp holder 41, so that the lighting lamp 5 is evenly distributed around the outer periphery of the telescopic rod 31 through the lamp post 4, thereby increasing the range of illumination of the lighting lamp 5.
[0036] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
