Description

Technical Field

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

[0002] At present, the electric lifting parts of electric lifting curtains or electric lifting hangers for household use are usually driven by winch-type devices, which makes them large in size, affects installation, and has poor aesthetics, especially difficult to install in a hidden manner. Taking electric lifting curtains as an example, there are too few hanging points of the steel wire rope of its electric lifting parts, which affects the lifting balance of the double-track curtains; and the existing electric lifting curtains do not have the function of fixing the curtain track, and cannot prevent the curtain track from swinging due to wind. In addition, the existing lifting electric curtains are powered by electric wires, so the power supply and power off are all manually operated. Summary of the invention

[0003] In order to solve the above technical problems, one of the objectives of the present invention is to provide a lifting frame rope set with a simple structure and stable lifting.

[0004] The cam is a device for activating a rotation of the first and second slings in a rotationally parallel manner so that the cam is in a position to move relative to the first sling and the second sling is moved relative to the first sling.

[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 cables, and when the movable block moves toward the second hanging wheel, the entire hanging beam will move downward under the traction of multiple hanging cables, that is, the hanging beam can be smoothly lifted 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 arranged on the fixing seat, and the plurality of tensioning adjustment members correspond one to one with the plurality of slings respectively, and 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.

[0009] The beneficial effect of the above technical solution is that: in this way, the tension of the first sling and the second sling can be adjusted by the corresponding tension adjustment members to coordinately adjust the horizontality of the suspension beam.

[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, and the corresponding end of the sling is connected to the reel. 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, and when the reel is rotated again, it will reel in the corresponding sling, thereby adjusting the horizontality of the suspension beam.

[0012] A second object of the present invention is to provide an electric lifting frame which has a simple structure and can be electrically lifted.

[0013] In order to achieve the above-mentioned purpose, another technical solution of the present invention is as follows: an electric lifting frame, including an electric linear driving component and the lifting frame rope group as described above, the electric linear driving component is arranged along the left and right directions, and its driving end is connected to the movable block, and the electric linear driving component is used to drive the movable block to move along the left and right directions.

[0014] The beneficial effect of the above technical solution is that the movable block is driven to move left and right by using the electric linear drive member 12, so that the structure is simple and compact.

[0015] In the above technical solution, two lifting frame rope groups are provided, and the two lifting frame rope groups are spaced apart in the front-to-back direction, and the electric linear drive is located between the two lifting frame rope groups, and the two movable blocks are connected to the driving end of the electric linear drive, and the electric linear drive drives the two movable blocks to move synchronously and in the same direction.

[0016] The beneficial effect of the above technical solution is that one electric linear drive can simultaneously drive two lifting frame rope groups to operate synchronously.

[0017] In the above technical solution, the two hanging beams are integrally formed into a straight strip plate, and the multiple hanging ropes corresponding to each lifting frame rope group are respectively connected to the corresponding sides of the hanging beam.

[0018] The beneficial effect of the above technical solution is that: in this way, the two lifting frame rope groups share a straight strip plate as a hanging beam, which makes the hanging beam wider and more stable during lifting.

[0019] In the above technical solution, a positioning male component is provided at the upper end of the hanging beam, a positioning female component is provided between the two lifting frame rope groups, and the positioning female component is vertically aligned with the positioning male component. When the electric linear drive component drives the hanging beam to move upward to the upper limit position, the positioning male component and the positioning female component are engaged with each other to limit the position of the hanging beam.

[0020] The beneficial effect of the above technical solution is that when the hanging beam moves upward to the upper limit position, the positioning female component and the positioning male component are engaged to prevent the hanging beam from swinging under the blowing of wind.

[0021] A third object of the present invention is to provide a lifting curtain assembly which has a simple structure and is convenient for disassembling and assembling the curtain cloth.

[0022] In order to achieve the above-mentioned purpose, another technical solution of the present invention is as follows: a lifting curtain assembly, including a curtain track, a curtain cloth and the electric lifting frame as described above, the curtain track is installed at the lower end of the hanging beam, and the curtain cloth is installed on the curtain track.

[0023] The beneficial effect of the above technical solution is that 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 with a ladder to remove the curtain cloth from the curtain track.

[0024] The curtain track described in the above technical solution is an electric curtain track, and also includes an electric connector male part arranged at the upper end of the hanging beam and an electric connector female part arranged between the two lifting frame rope groups, and the electric connector male part is vertically aligned with the electric connector female part, the electric connector male part is electrically connected to the curtain track, and the electric connector female part is electrically connected to the mains, and when the electric lifting frame drives the hanging beam to move upward to the upper limit position, the electric connector female part is plugged into the electric connector male part to supply power to the curtain track, or the electric lifting frame drives the hanging beam to move downward until the electric connector female part is separated from the electric connector male part to release the power supply to the curtain track.

[0025] The beneficial effect of the above technical solution is that the entire curtain fabric can be automatically opened or closed by the curtain track, and the degree of automation is high. In addition, the wire-free power supply required by the curtain can be realized, that is, when the electric lifting frame drives its hanging beam to move upward to the upper limit position, the electric connector female part and the electric connector male part are plugged into each other to realize power supply to the curtain track, and when the electric lifting frame drives its hanging beam downward, the electric connector female part and the electric connector male part are separated from each other to realize power off of the curtain track.

The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0056] Example 1

[0057] like Figure 1-Figure 4As shown, this embodiment provides a lifting frame rope group, including a hanging beam 111, a first hanging wheel 112, a second hanging wheel 113, a sling 114, a fixed seat 115 and a movable block 116, the sling 114 includes a first sling 114a and a second sling 114b, the hanging beam 111 is horizontally arranged in the left-right direction, the first hanging wheel 112 and the second hanging wheel 113 are spaced apart above the hanging beam 111 in the left-right direction, the fixed seat 115 is located between the first hanging wheel 112 and the second hanging wheel 113, the movable block 116 is slidably placed between the first hanging 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 sling 114a and the second sling 114b They are respectively connected to the fixed seat 115, the other end of the first sling 114a bypasses 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 bypasses 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, so that 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 respectively 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 (no further details are given here).

[0059] The first reversing member 117 includes a plurality of first reversing sheaves 1171, and the plurality of first reversing sheaves 1171 correspond to the plurality of slings 114 one by one. Each sling 114 bypasses the corresponding first reversing sheave 1171 at the movable block 116 to perform reversal and fold back. In this embodiment, the plurality of first reversing sheaves are spaced apart along the front-to-back direction on the corresponding side of the movable block, and the plurality of first reversing sheaves share a first wheel shaft 1172 horizontally distributed along the front-to-back direction. In this embodiment, two slings are provided, so 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 tension adjusting members 119 are arranged on the fixing seat 115, and the plurality of tension adjusting members 119 correspond to the plurality of slings 114 one by one, and the ends of the first sling 114a and the second sling 114b away from the suspension beam 111 are connected to the fixing seat 115 through the corresponding tension adjusting members 119, so that the tension of the first sling and the second sling can be adjusted by the corresponding tension adjusting members to coordinately adjust the horizontality of the suspension beam, wherein the tension adjusting members 119 are connected to the fixing seat 115, and the tension of the first sling and the second sling can be adjusted by the corresponding tension adjusting members to coordinately adjust the horizontality of the suspension beam, and the tension adjusting members 119 are connected to the fixing seat 115 ... The adjusting member 119 includes a vertically arranged reel 1191, and the reel 1191 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 tension 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 through the first suspension wheel and the 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 may be a hollow structure, and a plurality of cable entry holes 1152 are arranged on the side of the lower end of the fixed seat 115 close to the movable block 116, which are spaced apart along the front-to-back direction and connected to the interior of the fixed seat. The plurality of reels 1191 are vertically arranged in the fixed seat 115 (one end or both ends of the reels 1191 may be provided with a one-way bearing 1192), and are spaced apart along the front-to-back direction in the fixed seat 115, and 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 groove. Angle slot (the hexagonal slot is used for inserting an hexagonal wrench and twisting the reel so that the reel can reel in the sling), and the multiple cable entry holes 1152 correspond to the multiple reels 1191 one by one and are aligned with each other. The reel 1191 can also be a hollow shaft, and its side wall has an eyelet 11911. The corresponding end of the sling 114 can pass through the corresponding cable entry hole 1152 and the eyelet 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 eyelet).

[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 distribution along the front-to-back direction may 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).

By arranging two second slings and two second hanging wheels, and the two second hanging wheels are spaced apart along the left-right direction, three-point suspension of the hanging beam can be realized 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 groove wheels, and four second rope passing holes are provided (the first sling corresponds to two second rope passing holes, and the two second slings each correspond to one second rope passing hole, and of course the two second slings can also share one second rope passing hole).

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

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

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 groove wheels may be mounted on a mounting block close to the first suspension wheel (specifically located 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 (which is similar to the arrangement of the first rope through hole and the second rope through hole, and will not be described in detail here). Fig.11 As shown, the fixing seat can be integrally formed with the mounting block adjacent thereto.

[0080] At this time, there are two hanging beams, and the two hanging beams are raised and lowered synchronously and 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
