Description

Technical Field

[0001] This utility model relates to the field of chandelier lifting technology, specifically to a chandelier structure with adjustable height. Background Technology

[0002] Currently, in adjustable chandeliers that use multiple hanging ropes, the ropes are typically used to suspend and adjust the height of the chandelier. However, when multiple ropes work together, they can easily become entangled during the lifting and lowering process. This entanglement not only affects the aesthetics and stability of the chandelier but may also prevent it from lifting and lowering properly, and in severe cases, may even pose a safety hazard.

[0003] A search revealed a Chinese patent with publication number CN215674967U, which discloses an adjustable lifting chandelier. This patent features four LED tubes arranged in a grid pattern, connected by a pivot, and a pressing and fixing structure between the hanging ropes and the base box. The chandelier is easy to manually adjust in height, easy to transport, and has a simple structure and low cost. However, the patent mainly improves the chandelier in terms of transportation, without mentioning the lifting issue. In the method of using multiple hanging ropes for lifting, the ropes may become tangled due to wind, vibration, or improper operation. Once the ropes are tangled, a lot of time and effort is required to untangle them, which not only increases maintenance costs but may also affect the normal use of the chandelier.

[0041] In order to make the content of the utility model more easily be clearly understood, the utility model is further explained in detail below according to specific embodiments and in conjunction with the drawings.

[0042] Embodiment one

[0043] As Figures 1-6 shown, a lifting adjustable ceiling lamp structure includes:

[0044] The ceiling lamp main body 1 is connected with a plurality of interval arranged hanging ropes 2, and the ceiling lamp main body 1 is connected with one end of the hanging rope 2.

[0045] The support plate 3 is provided with a plurality of through holes 31 corresponding to the hanging rope 2, and the hanging rope 2 passes through the corresponding through hole 31.

[0046] Lifting assembly 4 is located inside support plate 3. Lifting assembly 4 includes lifting motor 41 and take-up roller 42. Lifting motor 41 is connected to take-up roller 42 to drive take-up roller 42 to rotate. The other ends of several suspension ropes 2 are wound around take-up roller 42.

[0047] The take-up roller 42 is connected to several spaced-apart separator rings 43, and a take-up space 44 is formed between two adjacent separator rings 43. Several suspension ropes 2 are located in the corresponding take-up spaces 44.

[0048] like Figure 5 As shown, the take-up roller 42 has several circumferentially distributed sliding grooves, and the inner side of several separator rings 43 is connected to a sliding block 56 opposite to the sliding groove. An elastic element is connected inside the sliding groove, and the elastic element is connected to the sliding block 56 on each separator ring 43 respectively.

[0049] The support plate 3 is provided with a first protective component 5, which includes a linear drive mechanism and two push plates 54. The linear drive mechanism is connected to the two push plates 54 to drive the two push plates 54 to move.

[0050] The two push plates 54 are adapted to compress the two outermost partition rings 43 when driven to move, thereby changing the size of each winding space 44 and limiting the corresponding suspension rope 2 in each winding space 44.

[0051] like Figures 6-7 As shown, the elastic element is a spring 57. The corresponding sliding blocks 56 on two adjacent separating rings 43 are connected by springs 57. One side of the sliding block 56 on the two outermost separating rings 43 is connected to the inner wall of the sliding groove by springs 57.

[0052] like Figure 7 As shown, a cover plate 58 is provided in the sliding groove, and a limiting groove 59 is provided on the cover plate 58. The sliding block 56 is slidably disposed in the limiting groove 59.

[0053] like Figure 5 As shown, the linear drive mechanism includes a bidirectional screw 52, ​​two transmission sleeves 53, and a linear motor 51;

[0054] Two transmission sleeves 53 are connected to two push plates 54 respectively. The two transmission sleeves 53 are respectively mounted on two oppositely arranged threads of the bidirectional screw 52. The linear motor 51 is connected to the bidirectional screw 52 to drive the bidirectional screw 52 to rotate, thereby driving the two transmission sleeves 53 to move along the axial direction of the bidirectional screw 52.

[0055] like Figure 5 , Figure 8 As shown, a guide groove is provided in the support plate 3, and guide plates 55 are connected to both transmission sleeves 53. The guide plates 55 are slidably disposed in the guide groove.

[0056] The working principle of the embodiment is as follows:

[0057] The overall structure is divided into two ceiling lamp bodies 1 and a support plate 3, the support plate 3 is used for being fixed on a wall body, specifically, a bolt or the like can be used to butt joint the same, not shown in the figure, the ceiling lamp body 1 is divided into a shell part and an LED lamp tube part, a plurality of hooks are arranged on the shell part, one end of the hanging rope 2 is wound on the hook, and the other end is wound on the winding roller 42 after passing through the through hole 31 on the support plate 3;

[0058] The plurality of hooks can select the required number of hanging ropes 2 according to the actual situation and are hung on the corresponding hooks, a plurality of separation rings 43 are arranged on the winding roller 42, a winding space 44 is formed between adjacent separation rings 43, the number of winding spaces 44 is the same as the number of hooks, the other end of the plurality of hanging ropes 2 is wound in the corresponding winding space 44, the hanging ropes 2 do not interfere with each other, the winding of the hanging rope 2 on the winding roller 42 can be connected according to the different materials selected by the hanging rope 2, this part belongs to the prior art, and will not be described in detail here, when the ceiling lamp body 1 needs to be lifted, only the lifting motor 41 is started to drive the winding roller 42 to rotate, the winding or loosening of all the hanging ropes 2 is controlled to follow the rotation of the winding roller 42, so as to realize the lifting of the ceiling lamp body 1, due to the arrangement of the separation ring 43, each hanging rope 2 is located in the independent winding space 44 and does not interfere with each other, and the problem of mutual winding of the plurality of hanging ropes 2 does not occur;

[0059] After the lifting work is completed, the hanging rope 2 should normally be in a static device, but when the winding roller 42 and the lifting motor 41 are out of control or the connection between the hanging rope 2 and the winding roller 42 is not firm, the hanging rope 2 will slide down under the influence of the weight of the hanging rope 2 body, the suddenly descending ceiling lamp body 1 will cause a safety hazard, therefore, the first protection assembly 5 is arranged;

[0060] When the lifting motor 41 is not working, the first protective component 5 will start the linear motor 51 to drive the bidirectional screw 52 to rotate. When the bidirectional screw 52 rotates, it drives the two externally mounted transmission sleeves 53 to move towards each other. The transmission sleeves 53 and the bidirectional screw 52 can be assembled with ball nuts. This connection method and the working principle of the bidirectional screw 52 are existing technologies and will not be described in detail here. Each of the two transmission sleeves 53 is connected to a push plate 54. Driven by the bidirectional screw 52, ​​the two push plates 54 move towards each other, squeezing the two outermost separator rings 43. After being squeezed, the separator rings 43 move in the sliding groove of the take-up roller 42 through the sliding block 56. At the same time, the spring 57 contracts as it moves. With the continuous squeezing of the push plates 54, all the separator rings 43 are squeezed. All three rings converge towards the center. During the convergence process, the winding space 44 formed between the two adjacent separating rings 43 continuously decreases until the lifting rope 2 in the winding space 44 is clamped, achieving the first layer of protection and preventing the lifting rope 2 from suddenly slipping out of control. At this time, the distance that the two push plates 54 move towards each other on the bidirectional screw 52 also reaches the maximum stroke. When it is necessary to control the lifting motor 41 to work again, it is only necessary to start the linear motor 51 again to drive the bidirectional screw 52 to rotate, so that the two push plates 54 can move in the opposite direction. The push plates 54 that move in the opposite direction gradually release the pressure on the separating ring 43. The separating ring 43 that loses pressure is reset by the spring 57. This part mainly improves the safety of use by setting a clamping component at the winding roller 42.

[0061] It should be noted that a cover plate 58 is provided in the sliding groove. The limiting groove 59 opened on the cover plate 58 allows the sliding block 56 to pass through without affecting the normal movement of the separating ring 43. However, the size of the limiting groove 59 is smaller than the diameter of the spring 57 to prevent the spring 57 from bending and protruding outside the sliding groove after being squeezed.

[0062] Example 2

[0063] like Figure 8 As shown, this embodiment further includes the following structure based on embodiment one: a second protective component 6 is provided in the support plate 3, the second protective component 6 includes a rotary drive mechanism and a plurality of extrusion plates 63, the plurality of extrusion plates 63 respectively corresponding to the through hole 31;

[0064] The rotary drive mechanism is connected to the extrusion plate 63 to drive the extrusion plate 63 to move toward the corresponding through hole 31, thereby extruding the corresponding hanging rope 2 passing through the through hole 31.

[0065] like Figure 8 As shown, the rotary drive mechanism includes a rotary motor 65, a drive gear 64, and a driven gear ring 62. Both the drive gear 64 and the driven gear ring 62 are rotatably mounted in the support plate 3, and the drive gear 64 meshes with the driven gear ring 62.

[0066] A rotary motor 65 is installed inside the support plate 3, and the rotary motor 65 is connected to the drive gear 64 to drive the drive gear 64 to rotate.

[0067] Several extrusion plates 63 are connected to the driven gear ring 62.

[0068] like Figure 8 As shown, a baffle 61 is provided on the side of a plurality of through holes 31 near the extrusion plate 63. The plurality of baffles 61 correspond to the plurality of extrusion plates 63. The extrusion plate 63 is adapted to be driven to move toward the corresponding baffle 61, thereby clamping and limiting the suspension rope 2 passing through the corresponding through hole 31.

[0069] The working principle of this embodiment is as follows:

[0070] A second protective component 6 is installed at the position where the hoisting rope 2 passes through the through hole 31. After the lifting control is completed and the lifting motor 41 stops working, the rotary motor 65 is started to drive the drive gear 64 to rotate. The drive gear 64 meshes with the driven gear ring 62 to achieve the rotation of the driven gear ring 62. The driven gear ring 62 is provided with a pressing plate 63 corresponding to the number of through holes 31. Under the drive of the driven gear ring 62, the pressing plate 63 moves to the corresponding through hole 31. When it moves above the through hole 31, it will squeeze the hoisting rope 2 passing through the through hole 31. The part of the hoisting rope 2 that is squeezed and bent is located between the pressing plate 63 and the inner wall of the support plate 3, thereby restricting the hoisting rope 2 and preventing the hoisting rope 2 from slipping uncontrollably.

[0071] In addition, a baffle 61 is provided at the through hole 31. After the extrusion plate 63 moves above the through hole 31, in addition to the extrusion plate 63 and the inner wall of the support plate 3 extruding the rope 2, the outer surface of the extrusion plate 63 and the inner side of the baffle 61 also extrude the rope 2, which further improves the ability to restrict the rope 2.

[0072] When it is necessary to control the lifting, start the rotary motor 65 to reverse the direction, so that the pressing plate 63 moves in the opposite direction and releases the restriction on the hanging rope 2 at the through hole 31. Then the lifting motor 41 can be started again to control the height of the chandelier body 1.

[0073] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
