Description

Technical Field

[0001] The utility model belongs to the technical field of lifting frames, and in particular relates to a lifting frame rope group, an electric lifting frame and a lifting curtain assembly. Background Art

[0002] Currently, the electric lift components of household electric curtains and electric clothes hangers are typically driven by winches. This makes them bulky, hindering installation, aesthetically pleasing, and difficult to conceal. For example, electric curtains have too few suspension points for their wire ropes, affecting the balance of the dual-track curtains. Existing electric curtains also lack a fixed curtain track function, preventing them from swinging in the wind. Furthermore, existing electric curtains are powered by wires, requiring manual power on and off. Utility Model Content

[0004] and a second sling attached to the base, the second sling being attached to the base and the second sling being attached to the base.

[0005] The beneficial effect of the above technical solution is that when the movable block moves toward the first hanging wheel, the entire hanging beam will move upward under the traction of multiple hanging ropes, and when the movable block moves toward the second hanging wheel, the entire hanging beam will move downward under the traction of multiple hanging ropes, that is, the hanging beam can be smoothly raised and lowered by driving the movable block to move left and right, and the hanging beam is always in a horizontal state during the lifting process.

[0006] In the above technical solution, two second hanging wheels are provided, two second slings are provided, and the two second hanging wheels correspond to the two second slings one by one, and the two second hanging wheels are spaced apart in the left-right direction.

[0007] The beneficial effect of the above technical solution is that by arranging two second slings and two second sling wheels, and the two second sling wheels are spaced apart in the left and right directions, when the sling beam is long, three-point suspension of the sling beam can be achieved, thereby making the sling beam more stable and having better load-bearing performance.

[0008] In the above technical solution, a plurality of tensioning adjustment members are provided on the fixing seat, and the plurality of tensioning adjustment members correspond one to one with the plurality of slings. The ends of the first sling and the second sling away from the suspension beam are connected to the fixing seat through the corresponding tensioning adjustment members.

[0010] The tensioning adjustment member in the above technical solution includes a vertically arranged reel, which is rotatably mounted on the fixed seat through a one-way bearing. The corresponding end of the sling is connected to the reel, and the reel is rotated to reel and tension the corresponding sling.

[0011] The beneficial effect of the above technical solution is that the reel is rotatably mounted on the fixed seat using a one-way bearing, so that the reel can only rotate in one direction. When the reel is rotated again, it will reel in the corresponding sling, thereby adjusting the horizontality of the suspension beam.

DETAILED DESCRIPTION

[0055] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in a very simplified form and are not in exact proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0056] Example 1

[0057] like Figures 1-4As shown, this embodiment provides a lifting frame rope group, including a lifting beam 111, a first lifting wheel 112, a second lifting wheel 113, a lifting rope 114, a fixed seat 115 and a movable block 116, the lifting rope 114 includes a first lifting rope 114a and a second lifting rope 114b, the lifting beam 111 is horizontally arranged in the left-right direction, the first lifting wheel 112 and the second lifting wheel 113 are spaced apart above the lifting beam 111 in the left-right direction, the fixed seat 115 is located between the first lifting wheel 112 and the second lifting wheel 113, the movable block 116 is slidably placed between the first lifting wheel 112 and the fixed seat 115, the movable block 116 is provided with a first reversing member 117, the fixed seat 115 is provided with a second reversing member 118, one end of the first lifting rope 114a and the second lifting rope 114b They are respectively connected to the fixed seat 115, and the other end of the first sling 114a passes around the first reversing member 117, the second reversing member 118 and the first hanging wheel 112 in sequence, and is pulled downward to be connected to the hanging beam 111. The other end of the second sling 114b passes around the first reversing member 117 and the second hanging wheel 113 in sequence, and is pulled downward to be connected to the hanging beam 111. The movable block 116 moves left and right under the action of external force so that the first sling 114a and the second sling 114b drive the hanging beam 111 to move up and down. In this way, when the movable block moves toward the first hanging wheel, the entire hanging beam will move upward under the traction of multiple slings, and when the movable block moves toward the second hanging wheel, the entire hanging beam will move downward under the traction of multiple slings, that is, the lifting and lowering of the hanging beam can be achieved by driving the movable block to move left and right.

[0058] The movable block 116 is provided with a first cable hole 1161 (only one is required) for the first sling 114a to pass through left and right, and the fixed seat 115 is provided with a second cable hole 1151 for the first sling 114a and the second sling 114b to pass through left and right (because the first sling needs to be folded back at the fixed seat, the first sling needs to correspond to two second cable holes 1151, and the second sling only passes through the fixed seat once, so the second sling only corresponds to one second cable hole 1151. In this embodiment, one first sling and one second sling are each provided, so three second cable holes are provided). The first cable hole 1161 and the second cable hole 1151 are provided at positions where the first sling 114a and the second sling 114b can pass straight through the corresponding movable block 116 and the fixed seat 115 (not described here).

[0059] The first reversing member 117 includes a plurality of first reversing sheaves 1171, each corresponding one to each of the slings 114. Each sling 114 passes around a corresponding first reversing sheave 1171 at the movable block 116 to reverse and return. In this embodiment, the plurality of first reversing sheaves are spaced apart along the front-to-back direction on corresponding sides of the movable block, and the plurality of first reversing sheaves share a first wheel axle 1172 horizontally disposed along the front-to-back direction. In this embodiment, two slings are provided, and therefore two first reversing sheaves are provided.

[0060] The second reversing member 118 includes a second reversing groove wheel 1181 and a second wheel axle 1182. The second reversing member 118 is arranged on the side of the fixed seat 115 away from the movable block 116. The second reversing groove wheel 1181 is for the first sling 114a to bypass to reverse and turn back, and the second reversing groove wheel 1181 is coaxially installed on the second wheel axle 1182. The second wheel axle 1182 can be arranged vertically or in the front-to-back direction.

[0061] like Figure 5 and Figure 6 As shown, in the above technical solution, a plurality of tensioning adjusting members 119 are provided on the fixing seat 115, and the plurality of tensioning adjusting members 119 correspond to the plurality of slings 114 respectively. The ends of the first sling 114a and the second sling 114b away from the beam 111 are connected to the fixing seat 115 through the corresponding tensioning adjusting members 119, so that the tension of the first sling and the second sling can be adjusted by the corresponding tensioning adjusting members to coordinately adjust the horizontality of the beam, wherein the tensioning The adjusting member 119 includes a vertically arranged reel 1191, which is rotatably mounted on the fixed seat 115 through a one-way bearing 1192. The corresponding end of the sling 114 is connected to the reel 1191. The reel 1191 is rotated to reel and tighten the corresponding sling 114. The reel is rotatably mounted on the fixed seat using a one-way bearing, so that the reel can only rotate in one direction. When the reel is rotated again, it will reel in the corresponding sling, thereby adjusting the horizontality of the suspension beam.

[0062] In this embodiment, one end of the first sling and the second sling connected to the suspension beam is vertically led down via a first suspension wheel and a second suspension wheel respectively. In this embodiment, the first suspension wheel and the second suspension wheel are equivalent to fixed pulleys.

[0063] In this embodiment, the inner lower end of the fixed seat 115 can be a hollow structure, and a plurality of cable holes 1152 are provided on the side of the lower end of the fixed seat 115 close to the movable block 116. The plurality of reels 1191 are vertically arranged in the fixed seat 115 (one end or both ends of the reel 1191 can be provided with a one-way bearing 1192), and are spaced apart in the front-to-back direction in the fixed seat 115. The lower end of each reel 1191 passes through the lower end of the fixed seat 115, and the inner lower end of the reel 1191 is provided with an inner hexagonal screw thread. Angle slot (the hexagonal slot is used for inserting an hexagonal wrench and twisting the reel so that the reel can reel up the sling), and the multiple cable entry holes 1152 correspond one-to-one to the multiple reels 1191 and are aligned with each other. The reel 1191 can also be a hollow shaft, and there is a hole 11911 on its side wall. The corresponding end of the sling 114 can pass through the corresponding cable entry hole 1152 and the hole 11911 in turn and enter the corresponding reel 1191, and be knotted on the reel 1191 to be connected to the reel 1191 (the sling will form an expanded structure when it is knotted in the reel, so it is not easy to loosen from the hole).

[0064] Preferably, in this embodiment, there are only two slings, so only two reels are required.

[0065] like Figure 4 As shown, in this embodiment, in order to stagger the first sling and the second sling between the movable block and the fixed seat, but ensure that the connection between the first sling and the second sling and the suspension beam is aligned left and right, two horizontally arranged and staggered distributions in the front-to-back direction can be added between the first lifting wheel and the movable block (of course, the transverse groove wheels 1121 that are staggered in the left and right directions can also be simultaneously provided, and the first sling needs to be S-shaped around the two transverse groove wheels between the first lifting wheel and the movable block, so that the first sling and the second sling sent through the two transverse groove wheels are staggered in the front-to-back direction).

[0067] Same as Example 1, except that Figure 7 and Figure 8 As shown, in the above technical solution, two second hanging wheels 113 are provided, two second slings 114b are provided, and the two second hanging wheels 113 correspond to the two second slings 114b one by one, and the two second hanging wheels 113 are spaced apart along the left and right directions. By arranging two second slings and two second hanging wheels, and the two second hanging wheels are spaced apart along the left and right directions, three-point suspension of the hanging beam can be achieved when the hanging beam is long, thereby making the suspension of the hanging beam more stable and having better load-bearing performance.

[0068] In this embodiment, there are three slings (one first sling and two second slings), so there are two first reversing sheaves, and four second sling holes are provided (the first sling corresponds to two second sling holes, and the two second slings each correspond to one second sling hole. Of course, the two second slings can also share one second sling hole).

[0069] At this time, the three slings work together to lift the beam, and the connection points of the three slings and the beam are spaced apart along the length of the beam.

[0070] like Figure 5 As shown, in this embodiment, the three reels can be distributed at intervals in an oblique manner (ie, distributed at intervals in the front-to-back direction and the left-to-right direction, so that the distance between two adjacent reels can be larger).

[0071] Example 3

[0072] like Figures 9-13 As shown, this embodiment provides an electric lifting frame, including an electric linear drive component 12 and a lifting frame rope group 11 as described in Example 1 or Example 2, wherein the electric linear drive component 12 is arranged along the left and right directions, and its driving end is connected to the movable block 116, and the electric linear drive component 12 is used to drive the movable block 116 to move along the left and right directions. By adopting the electric linear drive component 12 to drive the movable block to move left and right, its structure is simple and compact.

Preferably, the driving motor 121 is close to the first hanging wheel, the driving block 124 is integrally formed with the movable block 116, and the mounting block 125 close to the second hanging wheel is integrally formed with the fixed seat.

[0075] In this embodiment, the two transverse sheaves may be mounted on a mounting block close to the first suspension wheel (specifically, on a side of the mounting block away from the movable block), and the mounting block close to the first suspension wheel may also be provided with left and right through holes for the first suspension rope to pass through (similar to the arrangement of the first rope through hole and the second rope through hole, which will not be described in detail here). Figure 11 As shown, the fixing seat can be integrally formed with the mounting block adjacent thereto.

[0076] Example 4

[0077] Same as Example 3, except that Figures 14-19 As shown, in the above technical solution, two lifting frame rope groups 11 are provided, and the two lifting frame rope groups 11 are spaced apart in the front-to-back direction, and the electric linear drive 12 is located between the two lifting frame rope groups 11, and the two movable blocks 116 are both connected to the driving end of the electric linear drive 12. The electric linear drive 12 drives the two movable blocks 116 to move synchronously and in the same direction, so that one electric linear drive can simultaneously drive the two lifting frame rope groups to operate synchronously.

[0078] In this embodiment, the two fixing seats can be extended to be integrally formed, and the two movable blocks can also be extended to be integrally formed (and can even be integrally formed with the driving end of the electric linear drive member 12).

[0079] In this embodiment, the driving block 124 is integrally formed with the two movable blocks, the mounting block 125 close to the second hanging wheel is integrally formed with the two fixed seats, and two sliding rods are set in this application, and the screw rod is located between the two sliding rods.

[0080] At this time, there are two hanging beams, and the two hanging beams rise and fall synchronously and are spaced apart in the front-to-back direction. The electric lifting frame in this embodiment can be used as an electric clothes drying rack (each hanging beam can be used as a clothes drying rod for hanging clothes hangers).

[0081] Example 5

[0082] Same as Example 4, except that Figure 20-25As shown, in the above technical solution, the two hanging beams are integrally formed into a straight strip plate, and the multiple hanging ropes 114 corresponding to each lifting frame rope group 11 are respectively connected to the corresponding sides of the hanging beam 111, so that the two lifting frame rope groups share a straight strip plate as the hanging beam, which makes the hanging beam width larger and more stable during lifting; preferably, a positioning male part 13 is provided at the upper end of the hanging beam 111, and a positioning female part 14 is provided between the two lifting frame rope groups 11, and the positioning female part 14 is vertically aligned with the positioning male part 13, and when the electric linear drive part 12 drives the hanging beam 111 to move upward to the upper limit position, the positioning male part 13 and the positioning female part 14 are engaged with each other to limit the hanging beam 111, so that when the hanging beam moves upward to the upper limit position, the positioning female part 14 and the positioning male part 13 are engaged to prevent the hanging beam from swinging under the blowing of the wind.

[0083] In this embodiment, both the positioning female component 14 and the positioning male component 13 can be provided in plurality and correspond to each other. Specifically, both the positioning female component 14 and the positioning male component 13 can be provided in pairs. The two positioning male components 13 are spaced apart in the left-right direction at the middle of the upper end of the hanging beam, and the two positioning female components 14 are spaced apart in the left-right direction between the two lifting frame rope groups 11, and each positioning female component 14 is vertically aligned with the corresponding positioning male component 13.

[0085] Example 6

[0086] like Figure 26 As shown, this embodiment provides a lifting curtain assembly, including a curtain rail 2, a curtain cloth 3 and the electric lifting frame 1 as described in Example 5, wherein the curtain rail 2 is installed at the lower end of the hanging beam 111, and the curtain cloth 3 is installed on the curtain rail 2. Its structure is simple, so when the curtain cloth needs to be cleaned, the hanging beam can be directly lowered by the electric lifting frame, and there is no need to climb up a ladder to remove the curtain cloth from the curtain rail.

[0087] Example 7

[0088] Same as Example 6, except that Figure 27 and Figure 28 As shown, the curtain track 2 in the above technical solution is an electric curtain track, so that the entire curtain fabric can be automatically opened or closed by the curtain track, and the degree of automation is high.

[0089] The above technical solution also includes an electric connector male component 4 provided at the upper end of the hanging beam 111 and an electric connector female component 5 provided between the two lifting frame rope groups 11, and the electric connector male component 4 is vertically aligned with the electric connector female component 5, the electric connector male component 4 is electrically connected to the curtain track 2, and the electric connector female component 5 is electrically connected to the mains power. When the electric lifting frame 1 drives the hanging beam 111 to move upward to the upper limit, the electric connector female component 5 is plugged into the electric connector male component 4 to supply power to the curtain track 2, or the electric lifting frame 1 drives the hanging beam 111 downward to the point where the electric connector female component 5 is separated from the electric connector male component 4 to stop supplying power to the curtain track 2.
