Description

Technical Field

[0001] This utility model relates to the field of substation technology, and in particular to a telescopic red cloth curtain and its lifting device. Background Technology

[0002] The substation currently uses two types of red curtains: magnetic and rope. These curtains are made of pure cotton and polyester fabric, respectively. The following problems can easily arise when using these two types of curtains: Magnetic curtains: The magnets easily attract adjacent metal parts of the cabinets or the curtain itself, causing it to become loose and deformed (requiring frequent adjustments during inspections), increasing maintenance time and costs. Also, when folding, the magnets easily stick together, requiring manual separation and rearrangement; when unfolding, the magnet positions need to be repeatedly adjusted to ensure flatness.

[0003] Rope type: The four corner ropes need to be secured to hooks or fixed objects one by one, which takes about 1-2 minutes per operation. It is also easy to have to repeat the operation due to insecure fixation, which affects the work mood. In addition, the ropes are easy to tangle and knot, take up a lot of space when folded, and need to be straightened and secured again when unfolding, making the process complicated.

[0004] Furthermore, considering that the standard size of a substation panel is 800mm × 2000mm, the existing magnetic and rope-type red cloth curtains are too large. After installation, the fabric sags in the middle due to gravity, the edges of the magnetic curtains tend to curl up, and the tops of the rope-type curtains tend to wrinkle, resulting in poor overall flatness and affecting environmental compliance. In addition, the red cloth curtains are inconvenient to carry and lift after collection. Utility Model Content

[0005] In view of the above-mentioned problems in the prior art, this utility model is proposed.

[0006] The purpose of this invention is to provide a retractable red curtain, which aims to solve the problem of poor performance of existing red curtains.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a telescopic red curtain, which includes a pull rod assembly, including two sets of housings, a rotating rod disposed inside each set of housings, a first suction member disposed at the end of the housing, a second suction member disposed at the bottom of the housing, and a snap-fit ​​member disposed inside the second suction member;

[0008] A stretchable fabric, one end of which is wound around a set of the rotating rods, and the other end of which is wound around another set of the rotating rods.

[0009] As a preferred embodiment of the telescopic red curtain of this utility model, the shell is a semi-circular columnar body with a cavity on its inner side;

[0010] The housing also includes an upper column end disposed at the upper end of the cavity and a lower column end disposed at the lower end of the cavity.

[0011] As a preferred embodiment of the telescopic red curtain of this utility model, the upper column end includes an arc-shaped groove opened on its inner side;

[0012] The first adsorption element includes an upper magnet disposed inside the arc-shaped groove.

[0013] As a preferred embodiment of the telescopic red curtain of this utility model, the cavity includes a fixed circular hole opened at the center of its upper end face;

[0014] The stretchable fabric is a self-rolling fabric.

[0015] As a preferred embodiment of the telescopic red curtain of this utility model, the lower column end includes a fixing cavity opened on its inner side, two sets of fixing grooves disposed on both sides of the fixing cavity, and snap-fit ​​holes disposed on both sides of the fixing cavity.

[0016] As a preferred embodiment of the telescopic red curtain of this utility model, the second adsorption element includes a lower magnet disposed inside the fixing groove.

[0017] The upper magnets on the two sets of housings are magnetically attracted to each other, and the lower magnets are also attracted to each other.

[0018] As a preferred embodiment of the telescopic red curtain of this utility model, the snap-fit ​​component includes a snap-fit ​​seat disposed inside the fixed cavity, a mating hole disposed at one end of the snap-fit ​​seat, and a fixing rod disposed inside the snap-fit ​​seat.

[0019] As a preferred embodiment of the telescopic red curtain of this utility model, the snap-fit ​​seat includes a large circular hole in the middle, small circular holes on both sides of the large circular hole, and a horizontal groove on the end face of the snap-fit ​​seat.

[0020] As a preferred embodiment of the telescopic red curtain of this utility model, the fixing rod includes a spring disposed inside the large circular hole, abutments disposed on both sides of the spring, and an insert rod disposed outside the abutments.

[0021] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a lifting unit, including a handle groove formed on the circular surface of a cylinder, and a handle disposed inside the handle groove;

[0022] Both the handle groove and the handle are arc-shaped.

[0023] The beneficial effects of this utility model are that the red curtain fabric adopts a self-rolling design. When external force is applied, the red curtain can smoothly unfold from the center of the fabric to both sides; and once the external force is removed, it can quickly contract from both sides to the center, automatically returning to its original shape. This design greatly reduces the need for manual adjustment, making the operation process simpler and faster. The rotating rod 12 is installed inside the housing 11 and can rotate freely within the cavity 111. This design ensures that the fabric can run smoothly during stretching and contraction, avoiding problems such as jamming or tangling. If it is necessary to replace the telescopic fabric or adjust the warning signs, simply remove the rotating rod 12 from the snap-fit ​​15, replace the required parts, and reinsert it. The whole process does not require complicated tools, greatly improving maintenance efficiency. Since the two ends of the telescopic fabric are fixed on the rotating rods in the two sets of housings respectively, the length and position of the red curtain can be quickly adjusted according to actual needs, adapting to different sizes of cabinets or other facilities, increasing the flexibility of use.

[0032] Example 1

[0033] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a telescopic red curtain, including a pull rod assembly 1, which includes two sets of housings 11, a rotating rod 12 disposed inside each set of housings 11, a first adsorption member 13 disposed at the end of the housing 11, a second adsorption member 14 disposed at the bottom of the housing 11, and a snap-fit ​​member 15 disposed inside the second adsorption member 14.

[0034] The telescopic fabric 2 has one end wrapped around a set of rotating rods 12 and the other end wrapped around another set of rotating rods 12.

[0035] As an optional embodiment, the shell 11 is a semi-circular columnar body, and a cavity 111 is formed on its inner side;

[0036] The housing 11 also includes an upper column end 112 disposed at the upper end of the cavity 111, and a lower column end 113 disposed at the lower end of the cavity 111.

[0037] As an optional embodiment, the upper column end 112 includes an arcuate groove 1121 formed on its inner side;

[0038] The first adsorption element 13 includes an upper magnet 131 disposed inside the arc-shaped groove 1121.

[0039] As an optional embodiment, the cavity 111 includes a fixed circular hole 1111 formed at the center of its upper end face;

[0040] The stretchable fabric 2 is a self-rolling fabric.

[0041] As an optional embodiment, the lower column end 113 includes a fixing cavity 1131 opened on its inner side, two sets of fixing grooves 1132 disposed on both sides of the fixing cavity 1131, and snap-fit ​​holes 1133 disposed on both sides of the fixing cavity 1131.

[0042] As an optional embodiment, the second adsorption member 14 includes a lower end magnet 141 disposed inside the fixing groove 1132;

[0043] The upper magnets 131 on the two sets of housings 11 are magnetically attracted to each other, and the lower magnets 141 are also attracted to each other.

[0044] As an optional embodiment, the snap-fit ​​component 15 includes a snap-fit ​​seat 151 disposed inside the fixing cavity 1131, a mating hole 152 disposed at one end of the snap-fit ​​seat 151, and a fixing rod 153 disposed inside the snap-fit ​​seat 151.

[0045] As an optional embodiment, the card holder 151 includes a large circular hole 1511 formed in the middle therein, small circular holes 1512 disposed on both sides of the large circular hole 1511, and a transverse groove 1513 disposed on the end face of the card holder 151.

[0046] As an optional embodiment, the fixing rod 153 includes a spring 1531 disposed inside the large circular hole 1511, abutments 1532 disposed on both sides of the spring 1531, and a plug rod 1533 disposed outside the abutments 1532.

[0047] In this embodiment, the novel tool consists of a housing 11 assembly and a telescopic fabric 2. The housing 11 is a semi-circular cylindrical body with a cavity 111 on its inner side, which provides space for mounting and storing the telescopic fabric 2.

[0048] The upper end of the housing 11 is an upper column end 112. An arc-shaped groove 1121 is provided on the inner side of the upper column end 112. An upper magnet 131 is built into the arc-shaped groove 1121. A set of fixing round holes 1111 is provided at the center of the upper end face of the cavity 111. The fixing round holes 1111 can be hinged to the rotating rod 12, allowing the rotating rod 12 to rotate freely.

[0049] The lower end of the housing 11 is a lower column end 113, which has a fixing cavity 1131 at the lower end of the rotating rod 12. The fixing cavity 1131 can hold the locking piece 15. At the same time, the fixing cavity 1131 at the lower end of the housing 11 allows the rotating rod 12 to be locked into the locking piece 15. The telescopic fabric 2 is wrapped around the rotating rod 12. The two ends of the rotating rod 12 are not fixedly connected. The rotating rod 12 only serves to support and fix the telescopic fabric 2. Since the telescopic fabric 2 has self-rolling properties, it can ensure that after being stretched, the telescopic fabric 2 rotates around the rotating rod 12 under its own stretching action, thus achieving the effect of stretching and rolling up. In the case of its own stretching function, the telescopic fabric 2 will wrap around the rotating rod 12. During this process, the cavity 111 inside the housing 11 serves to ensure that the telescopic fabric 2 has sufficient shrinkage space inside the housing 11 after shrinking. Warning words are printed on the telescopic fabric 2 to warn personnel during operation.

[0050] In this embodiment, the telescopic function of the red curtain is not achieved by a spring, but by the self-rolling property of the telescopic fabric 2. This fabric can be an automatically shrinking PET film or it can have elastic metal wires on the inside, which can pull the entire telescopic fabric 2 up to achieve the telescopic purpose.

[0051] In this embodiment, a fixing cavity 1131 is provided on the lower column end 113, into which the snap-fit ​​member 15 can be inserted. Fixing grooves 1132 are also formed on both sides of the fixing cavity 1131, and the lower magnet 141 is embedded in the inner side of the fixing groove 1132 respectively.

[0052] The snap-fit ​​component 15 consists of a snap-fit ​​seat 151 fixedly snapped into the inner side of the fixed cavity 1131, mating holes 152 on both sides of the snap-fit ​​seat 151, and a fixing rod 153 on the inner side of the snap-fit ​​seat 151. The fixing rod 153 on the snap-fit ​​component 15 can be elastically snapped into the snap-fit ​​hole 1133 of the lower column end 113. At the same time, the mating hole 152 on one side of the snap-fit ​​seat 151 can allow the rotating rod 12 to be snapped in. The snap-fit ​​component 15 ensures that the telescopic fabric 2 can be quickly replaced when it is damaged or needs to be replaced with other warning signs.

[0053] In this embodiment, the upper column end 112 has an upper magnet 131, and the lower column end 113 has lower magnets 141 on both sides, which can be quickly adsorbed onto the metal screen cabinet.

[0054] Preferably, the telescopic fabric 2 is coated with a light-absorbing and light-emitting material, which absorbs light when there is a light source and emits light when there is no light source, so that a telescopic red curtain can play a good warning role in the night environment.

[0055] In this embodiment, the housing 11 is divided into two groups, which can be a left housing and a right housing. The telescopic fabric 2 is fixedly wrapped around the left and right pull rods 12. After the snap fastener 15 is inserted into the fixing cavity 1131, the lower end of the rotating rod 12 is inserted into the docking hole 152, and the housing 11 and the telescopic fabric 2 will become a whole.

[0056] When a retractable red curtain is unfolded, the warning lettering faces the semi-circular protrusion of the housing 11, which serves as a convenient warning. The upper magnet 131 and the lower magnet 141 are located on the semi-circular plane side of the housing 11, which makes it easy to attach to the metal screen cabinet.

[0057] When a retractable red cloth curtain is unfolded, the warning lettering faces the semi-circular protrusion of the housing 11, serving both to facilitate the use of the handle 32 and to provide a warning. The warning lettering may include phrases such as "Stop, High Voltage Danger," "Work Here," or "Operating Equipment," and the retractable cloth 2 will display different colors for different words, making it easy for personnel to distinguish between them. The upper magnet 131 and the lower magnet 141 are located on the semi-circular plane side of the housing 11, facilitating their attachment to the metal cabinet.

[0058] When the telescopic fabric 2 is in the retracted state, it is wrapped around the rotating rod 12. Without external force, the two shells 11 will be combined into a cylindrical whole by the telescopic fabric 2. With external force, the telescopic fabric 2 will unfold to both sides along the center of the fabric, and the warning lettering will also unfold to both sides along the center of the fabric. When the external force is removed, the telescopic fabric 2 will retract to the center of the fabric from both sides, and the warning lettering will also retract to the center of the fabric from both sides.

[0059] Preferably, due to the high resilience of the stretchable fabric 2, the installation and removal of this new type of red curtain can be completed within 2-3 seconds.

[0060] Under normal conditions, a retractable red curtain, such as Figure 4 As shown, the two shells 11 attract each other under the action of magnets, forming a scroll shape for easy storage.

[0061] Reference Figures 1-4 This embodiment provides a lifting device, including a lifting unit 3, including a handle groove 31 formed on the circular surface of a cylinder, and a handle 32 disposed inside the handle groove 31;

[0062] Both the handle groove 31 and the handle 32 are arc-shaped.

[0063] In this embodiment, the back of the housing 11 has a handle groove 31, and the handle groove 31 has a hinge hole near the top of the semi-circular column of the housing 11. The handle 32 is connected to the housing 11 through the hinge hole. The handle 32 can easily apply force to the housing 11, so that the housing 11 can be easily separated and closed. Also, when a telescopic red curtain is attached to the metal screen cabinet, the handle 32 can be used to quickly separate the telescopic red curtain from the metal screen cabinet.

[0064] Both the handle groove 31 and the handle 32 are arc-shaped, which facilitates the attraction of the two side shells 11 to each other under the action of magnets, forming a scroll shape, and the handle groove 31 and the handle 32 can be effectively hidden.

[0065] When in use, the operator holds the handles 32 on the outside of the two side shells 1 to separate the two side shells 11, causing the telescopic fabric 2 to rotate along the rotating rod 12, so that the telescopic fabric 2 is fully unfolded. The two side shells 11 are then attracted to the metal screen cabinet by the magnets 131 at the upper end and 141 at the lower end of the rod. At this time, the telescopic fabric 2 maintains its self-stretching property. If the magnets are released, the red curtain will return to its contracted state through the self-stretching property of the telescopic fabric 2.

[0066] During retraction, the operator holds the handles 32 on the outside of the two side shells 1 to separate the two side shells 11 from the metal cabinet. Due to the self-stretching property of the telescopic fabric 2, the telescopic fabric 2 is driven to rotate along the rotating rod 12, and the telescopic fabric 2 will also wrap around the rotating rod 12, thus retracting.

[0067] In summary, this red curtain fabric adopts a self-rolling design. When external force is applied, the red curtain can smoothly unfold from the center of the fabric to both sides; once the external force is removed, it can quickly contract from both sides back to the center, automatically returning to its original shape. This design greatly reduces the need for manual adjustment, making the operation process simpler and faster. The rotating rod 12 is installed inside the housing 11 and can rotate freely within the cavity 111. This design ensures that the fabric can move smoothly during stretching and contraction, avoiding problems such as jamming or tangling. If it is necessary to replace the telescopic fabric or adjust the warning signs, simply remove the rotating rod 12 from the locking piece 15, replace the required parts, and reinsert it. The entire process requires no complicated tools, greatly improving maintenance efficiency. Since the two ends of the telescopic fabric are fixed to the rotating rods in the two sets of housings respectively, the length and position of the red curtain can be quickly adjusted according to actual needs, adapting to different sizes of cabinets or other facilities, increasing the flexibility of use.

[0068] Importantly, the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model 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 this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
