Description

Technical Field

[0001] This invention relates to the field of hanging lights, specifically a hanging light lifting mechanism. Background Technology

[0002] Chandeliers are high-end decorative lighting fixtures suspended from indoor ceilings. Whether suspended by wires or iron rods, chandeliers should not be hung too low, as this can obstruct normal vision or cause glare. For example, in a dining room, the ideal height for a chandelier is to create a pool of light around the table without obstructing the view of people sitting at the table. Modern chandeliers are equipped with springs or height adjusters to suit different ceiling heights and needs.

[0003] The nautical-themed chandeliers originate from Spain, a country with a long maritime history. These lights come in both electric and oil-lit versions, making them ideal for interior designs seeking a distinctive style. Crystal chandeliers are suitable for living rooms, bedrooms, dining rooms, hallways, and hotel lobbies. Chandeliers come in a wide variety of styles, including European candelabra chandeliers, Chinese chandeliers, crystal chandeliers, parchment chandeliers, modern chandeliers, conical shade chandeliers, pointed flat shade chandeliers, waisted shade chandeliers, five-branched spherical chandeliers, magnolia shade chandeliers, and olive chandeliers. For residential use, chandeliers are available in single-bulb and multi-bulb versions; single-bulb chandeliers are often used in bedrooms and dining rooms, while multi-bulb chandeliers are more suitable for living rooms. The lowest point of the chandelier should be at least 2.2 meters from the ground.

[0004] To enrich the multiple uses of hanging lights, a lifting mechanism is installed on the hanging lights to assist in using them at different heights. However, during the lifting process, improper operation may cause the hanging lights to fall directly, which poses a certain risk to their use. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a hanging light lifting mechanism.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a hanging lamp lifting mechanism, including a mounting base and a lamp body; a mounting shell fixed to the lower end of the mounting base, wherein the mounting shell is provided with a lifting component for lifting the lamp body, and a protective component is provided on the mounting shell for protection when the descent is uncontrolled during the lifting process.

[0007] The lifting assembly includes a drive shaft rotatably connected to the mounting housing. A winding wheel is provided inside the mounting housing. The winding wheel is fixed to the drive shaft and is concentrically arranged with the drive shaft. A pull rope is wound on the winding wheel. One end of the pull rope passes through to the outside of the mounting housing and is connected to the lamp body through a sway-reducing assembly. A drive component for driving the drive shaft is provided on the outside of the mounting housing.

[0008] The driving component is a drive motor, which is mounted on the outside of the mounting housing. The output end of the drive motor is fixed to the drive shaft. A battery is mounted on the mounting base, and the battery is electrically connected to the drive motor.

[0009] The anti-sway assembly includes a mounting cylinder fixed to the upper end of the lamp body, a sliding plate slidably connected to the mounting cylinder, one end of the pull rope passing through the interior of the mounting cylinder and fixed to the sliding plate, the interior of the mounting cylinder being filled with damping fluid, the sliding plate having multiple damping holes, and a first spring for connecting the sliding plate being installed inside the mounting cylinder.

[0010] The protective assembly includes multiple limiting grooves formed on the drive shaft. The limiting grooves are located outside the mounting housing and arranged in a circular array. The outside of the mounting housing is connected to a limiting rod via a pushing assembly. The limiting rod is located directly above the limiting groove. A limiting assembly for blocking and limiting the limiting rod is provided on the outer side of the mounting housing. A drive disk is fixed to one end of the drive shaft. An unlocking assembly for unlocking the limiting assembly under high-speed rotation is provided on the drive disk.

[0011] The pushing assembly includes a fixed frame fixed to the outside of the mounting housing, a limiting rod slidably connected to the fixed frame, a circular plate fixed to the upper end of the limiting rod, and a second spring sleeved on the side wall of the limiting rod, with the two ends of the second spring connected to the circular plate and the fixed frame respectively.

[0012] The limiting component includes a transmission plate, which is connected to the outside of the mounting shell via a connecting component. A limiting baffle is fixed on the transmission plate, and the limiting baffle abuts against the lower end of the limiting rod to limit the movement.

[0013] The connecting assembly includes a fixing plate fixed to the outside of the mounting shell, a plurality of first sleeves fixed on the fixing plate, a first slide rod slidably connected to each first sleeve, one end of the first slide rod being fixed to a transmission plate, and a plurality of third springs connected between the fixing plate and the transmission plate, the third springs being sleeved on the outside of the first sleeves and the first slide rods.

[0014] The unlocking components are provided in multiple sets on the drive disk, and the multiple unlocking components are arranged in a ring array on the drive disk.

[0015] The unlocking component includes a second sleeve, one end of which is rotatably connected to the drive disc. A second slide rod is connected to the second sleeve via a fourth spring. The second slide rod is slidably connected to the second sleeve. A push ball for pushing against the transmission plate is fixed at the end of the second slide rod away from the second sleeve.

[0016] The beneficial effects of this invention are:

[0017] The present invention discloses a hanging light lifting mechanism. When improper operation or other reasons cause the light body to fall rapidly and uncontrollably, a limiting rod is inserted into the limiting slot through transmission. The limiting rod and the limiting slot together limit the drive shaft to stop rotating. By limiting the drive shaft, the pull rope is prevented from being released, thus stopping the light body from falling. This avoids the risk of the light body falling due to improper operation or other reasons, and facilitates safer and more stable operation of the hanging light. Attached Figure Description

[0029] like Figure 1-7 As shown, a hanging lamp lifting mechanism of the present invention includes a mounting base 101 and a lamp body 102; a mounting shell 2 fixed to the lower end of the mounting base 101, the mounting shell 2 being provided with a lifting component for lifting the lamp body 102, and a protective component for protecting the lamp body 102 when the descent is out of control during the lifting process.

[0030] It should be noted here that: when improper operation or other reasons cause the lamp body 102 to fall rapidly and uncontrollably, the protective component will stop the lamp body 102 from falling, avoiding the risk of the lamp body 102 falling due to improper operation or other reasons, and making the operation and use of the hanging lamp safer and more stable.

[0031] Specifically, the lifting assembly includes a drive shaft 301 rotatably connected to the mounting housing 2. A winding wheel 302 is provided inside the mounting housing 2. The winding wheel 302 is fixed on the drive shaft 301 and is concentrically arranged with the drive shaft 301. A pull rope 303 is wound on the winding wheel 302. One end of the pull rope 303 passes through to the outside of the mounting housing 2 and is connected to the lamp body 102 through a sway-reducing assembly. A drive component for driving the drive shaft 301 is provided on the outside of the mounting housing 2. The drive component is a drive motor 304. The drive motor 304 is installed on the outside of the mounting housing 2. The output end of the drive motor 304 is fixed to the drive shaft 301. A battery is installed on the mounting base 101. The battery is electrically connected to the drive motor 304.

[0032] It should be noted that: when the drive motor 304 is started, the drive shaft 301 is driven to rotate. During the rotation of the drive shaft 301, the take-up wheel 302 is driven to rotate. Through the rotation of the take-up wheel 302, the pull rope 303 is wound up or released. Through the connection of the various components on the anti-sway assembly, the lamp body 102 is driven to rise and fall, and the operating height of the lamp body 102 is adjusted, so that the hanging lamp can be operated and used in different ways.

[0033] Specifically, the anti-sway component includes a mounting cylinder 401 fixed to the upper end of the lamp body 102, a sliding plate 402 slidably connected to the mounting cylinder 401, one end of a pull rope 303 passing through the interior of the mounting cylinder 401 and fixed to the sliding plate 402, the interior of the mounting cylinder 401 being filled with damping fluid, the sliding plate 402 having multiple damping holes 403, and a first spring 404 for connecting the sliding plate 402 being installed inside the mounting cylinder 401;

[0034] It should be noted that during the lifting and lowering of the lamp body 102, the lamp body 102 will sway under force as the lifting and lowering proceeds. During the swaying, the sliding plate 402 is pulled by the pull rope 303 and the sliding plate 402 is pulled back to its original position by the first spring 404, causing the sliding plate 402 to reciprocate inside the mounting cylinder 401. During the reciprocating motion of the sliding plate 402, the damping fluid inside the mounting cylinder 401 passes through the damping hole 403, generating a damping mechanism. This reduces the probability of the lamp body 102 swaying under force during the lifting and lowering process, further ensuring the stability of the lifting and lowering adjustment of the lamp body 102.

[0035] Specifically, the protective component includes multiple limiting grooves 501 formed on the drive shaft 301. The limiting grooves 501 are located outside the mounting shell 2 and arranged in a circular array. The outside of the mounting shell 2 is connected to a limiting rod 502 via a pushing component. The limiting rod 502 is located directly above the limiting grooves 501. A limiting component for blocking and limiting the limiting rod 502 is provided on the outside of the mounting shell 2. A drive disk 9 is fixed to one end of the drive shaft 301. An unlocking component for unlocking the limiting component under high-speed rotation is provided on the drive disk 9.

[0036] It should be noted that when improper operation or other reasons cause the lamp body 102 to fall rapidly and uncontrollably, the descent of the lamp body 102 and the connection of the pull rope 303 will cause the winding wheel 302 and the drive shaft 301 to rotate rapidly. During the rapid rotation of the drive shaft 301, through transmission, one end of the limiting rod 502 is inserted into the inside of the limiting groove 501. The action of the limiting rod 502 against the limiting groove 501 limits the drive shaft 301 and prevents it from rotating. By limiting the drive shaft 301, the pull rope 303 is no longer released, and the descent of the lamp body 102 is stopped. This avoids the risk of the lamp body 102 falling due to improper operation or other reasons, and facilitates safer and more stable operation of the hanging lamp.

[0037] Specifically, the pushing component includes a fixed frame 601 fixed to the outside of the mounting shell 2, a limiting rod 502 slidably connected to the fixed frame 601, a circular plate 602 fixed to the upper end of the limiting rod 502, and a second spring 603 sleeved on the side wall of the limiting rod 502. The two ends of the second spring 603 are respectively connected to the circular plate 602 and the fixed frame 601.

[0038] It should be noted here that the second spring 603 facilitates the pushing of the limit rod 502.

[0039] Specifically, the limiting component includes a transmission plate 701, which is connected to the outside of the mounting shell 2 via a connecting component. A limiting baffle 702 is fixed on the transmission plate 701, and the limiting baffle 702 abuts against the lower end of the limiting rod 502 to limit the movement.

[0040] It should be noted here that the limiting baffle 702 prevents the limiting rod 502 from moving toward the limiting groove 501 by resisting the limiting rod 502.

[0041] Specifically, the connecting assembly includes a fixing plate 801 fixed to the outside of the mounting shell 2. Multiple first sleeves 802 are fixed on the fixing plate 801. A first slide rod 803 is slidably connected to each first sleeve 802. One end of the first slide rod 803 is fixed to the transmission plate 701. Multiple third springs 804 are connected between the fixing plate 801 and the transmission plate 701. The third springs 804 are sleeved on the outside of the first sleeves 802 and the first slide rods 803.

[0042] It should be noted that: the movement of the transmission plate 701 after being subjected to force is guided by multiple first sleeves 802 and first slide rods 803, and the reset movement of the transmission plate 701 after being subjected to force is facilitated by multiple third springs 804.

[0043] Specifically, multiple sets of unlocking components are provided on the drive disk 9, and the multiple unlocking components are arranged in a ring array on the drive disk 9;

[0044] It should be noted here that the stability of the unlocking transmission is improved by using multiple sets of unlocking components.

[0045] Specifically, the unlocking component includes a second sleeve 1001, one end of which is rotatably connected to the drive disk 9. A second slide rod 1002 is connected to the second sleeve 1001 via a fourth spring. The second slide rod 1002 is slidably connected to the second sleeve 1001. A push ball 1003 for pushing against the transmission plate 701 is fixed at the end of the second slide rod 1002 away from the second sleeve 1001.

[0046] It should be noted that when improper operation or other reasons cause the lamp body 102 to fall rapidly and uncontrollably, the descent of the lamp body 102 and the connection of the pull rope 303 will cause the winding wheel 302 and the drive shaft 301 to rotate rapidly. During the rapid rotation of the drive shaft 301, the centrifugal force on each of the second slide rods 1002 on the drive disc 9 will increase. Under the action of centrifugal force, the second slide rods 1002 will continue to slide outward on the second sleeve 1001. During the sliding of the second slide rods 1002, the push ball 1003 will abut against the transmission plate 701. Through the abutment between the push ball 1003 and the transmission plate 701, the transmission plate 701 will be driven to move under force. During the movement, under the guidance of each first sleeve 802 and the first slide rod 803, the transmission plate 701 will move towards the fixed plate 801.

[0047] Working principle: When using the hanging light, the mounting base 101 is installed on the top of the designated position, so that the light body 102 is in a suspended state. During the process of using the light body 102 in a suspended state, if it is necessary to adjust the height of the light body 102, the drive motor 304 is started. The drive motor 304 drives the drive shaft 301 to rotate. During the rotation of the drive shaft 301, the winding wheel 302 is rotated. Through the rotation of the winding wheel 302, the pull rope 303 is wound up or released. Through the connection of the various components on the sway-reducing assembly, the light body 102 is raised and lowered, and the height of the light body 102 is adjusted, so that the hanging light can be operated and used in different ways.

[0048] During the lifting and lowering process of the lamp body 102, the lamp body 102 will be subjected to force and shake as the lifting and lowering proceeds. During the shaking process, the sliding plate 402 is pulled by the pull rope 303 and the sliding plate 402 is pulled and reset by the first spring 404 after the movement, so that the sliding plate 402 reciprocates inside the mounting cylinder 401. During the reciprocating motion of the sliding plate 402, the damping fluid inside the mounting cylinder 401 passes through the damping hole 403, generating a damping mechanism, reducing the probability of the lamp body 102 shaking under force during the lifting and lowering process, and further ensuring the stability of the lifting and lowering adjustment of the lamp body 102.

[0049] When the lamp body 102 is raised or lowered by rotating the drive shaft 301, the rotation of the drive shaft 301 drives the drive disc 9 to rotate. During the rotation of the drive disc 9, under the action of centrifugal force, each of the second slide rods 1002 slides on the second sleeve 1001. Because the rotation speed of the drive disc 9 and the drive shaft 301 is relatively low at this time, the centrifugal force on each of the second slide rods 1002 is relatively small. Therefore, the sliding of the second slide rods 1002 does not abut against the transmission plate 701. However, due to improper operation or other reasons, When the lamp body 102 falls rapidly and uncontrollably, the descent of the lamp body 102 and the connection of the pull rope 303 cause the winding wheel 302 and drive shaft 301 to rotate rapidly. During the rapid rotation of the drive shaft 301, the centrifugal force on each of the second slide rods 1002 on the drive disc 9 increases. Under the action of centrifugal force, the second slide rods 1002 continue to slide outward on the second sleeve 1001. During the sliding of the second slide rods 1002, the push ball 1003 and the transmission plate 70... 1. Through the mutual resistance between the push ball 1003 and the transmission plate 701, the transmission plate 701 is driven to move under force. During the movement, guided by the first sleeves 802 and the first slide rods 803, the transmission plate 701 moves towards the fixed plate 801. During the movement of the transmission plate 701, the limiting baffle 702 moves synchronously. During the movement of the limiting baffle 702, the limiting baffle 702 no longer resists and limits the limiting rod 502. One end of the limiting rod 502 is in the second spring. Under the elastic force of the spring 603, it moves towards the drive shaft 301 and inserts one end of the limiting rod 502 into the limiting groove 501. Through the abutment between one end of the limiting rod 502 and the limiting groove 501, the drive shaft 301 is limited and stops rotating. By limiting the drive shaft 301, the pull rope 303 is no longer released, and the lamp body 102 stops descending. This avoids the risk of the lamp body 102 falling due to improper operation or other reasons, and facilitates safer and more stable operation of the hanging lamp.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
