Indoor personnel window self-rescue simple escape device for urban civil building high-rise fire

Abstract

The invention relates to a novel full-triangular bracket type device which is specially mounted outside a window of a modern high-rise civil building, and when a fire disaster occurs, a corridor and an elevator cannot escape, and the device is used for automatically escaping from the window of a home. A flat and square galvanized steel pipe with the wall thickness of 3mm and the specification of 50 * 100mm is adopted as a main framework; the special winding and unwinding wire which is resistant to smoke and fire burning, free of rust, free of oil, free of paint, soft in rigidity, durable and storage-resistant is manufactured by adopting the modes of electric welding, screw and screw rod assembling and the like and combining with a pure white steel thin stranded steel cable which is popular in the market and has the diameter of about 3-5mm. A net basket hanging mode is adopted, double-rope gravity self-sliding descending is achieved, and a handle automatically controls the device to safely fall to the ground for escape. The device can directly reduce the labor intensity of fire fighters for searching and rescuing in a fire scene. The window self-rescue escape device is a novel device which can help people trapped in a fire scene to carry out window self-rescue escape one by one.

Description

[0001] Technical field: This invention patent is to meet the actual needs of modern society and to solve the unexpected situation of fire in the high-rise buildings where ordinary civilians live or work in the process of production and life. The corridor is completely blocked by fireworks and cannot escape from the stairs; the elevator is trapped by power outage; life hangs on a thread, every second counts, and there is no external help. Using the patented project of this invention-the simple escape device for self-rescue at the window, emergency assistance is provided to rescue the existing people in the room and their own lives, and escape from the fire. In other words, the door cannot be opened now; the elevator cannot be used due to power outage; the rescue team has not arrived yet; what should the people in the high-rise building do? The fireworks are spreading upwards quickly. Why don't we use the windows around the floors on site to realize self-rescue and escape when the fireworks have not yet burned into the room? But there is no safe passage outside the window. Window escape requires special equipment. Today, we have invented a whole set of new devices that are specially used in such dangerous occasions and for escaping from windows. We have chosen a safe window that is away from the direction of the fire scene, and took out this invention patent project that is always available somewhere in the home: a simple self-rescue escape device for windows. After simple assembly, under the premise of not exceeding its maximum weight limit, one person or two light-weight people can fully realize self-rescue and escape from the window in the fire scene with the family members at a time. The device can also be used repeatedly for rescue. The young, old, and young men and women can use the simple self-rescue escape device of this invention to quickly slide down from the dangerous and burning floor from the indoor window where they are or the nearest safe window on the same floor, safely leave the fire scene, and safely reach the ground outside the building. It can not only safely save the lives of the family members in the fire scene, but also help the surrounding neighbors to escape smoothly from the dangerous scene. What a great feat it is. This is equivalent to the pioneering and exemplary role of "saving people from fire and water" played by professional urban fire brigades. We should vigorously promote it. In the future, we should make our best efforts to achieve comprehensive self-rescue and mutual rescue, and strive to achieve self-rescue of the lives of people in distress within the fire scene. Further realize and cooperate with and help firefighters to reduce the workload of search and rescue at the fire scene. Our latest invention patent project is such a new type of device dedicated to self-rescue of people trapped in the fire scene.

[0002] Background technology: In the current social reality, only professionals can truly master and practice a set of amazing rope high-altitude rappelling without any fireworks, and use and practice the "Spider-Man"-like descent technology. Instead of taking the elevator or stairs in a high-rise building, you can freely rappel down from a window in any direction indoors, and land safely, easily and quickly on the designated ground outside the building, ultimately achieving the goal of "self-rescue of a single person in a high-rise building".

[0003] Due to our current scientific level and the industrial production technology that matches it, we have not yet been able to design and manufacture new emergency rescue equipment that is suitable for all current construction and development needs. In other words: At present, although the equipment of our regular army has basically met the requirements of the existing large-scale urban construction and development, it actually lacks a certain scale of guerrilla-style auxiliary forces that match it. We need to improve the newer and better equipment in our modern urban construction to adapt to the needs of the continued deepening development of modern society under the new form. For example, from the perspective of the number of fire fighters and their equipment equipped on each modern new model fire truck of our active fire brigade, from the outside, every fire fighter involved in the firefighting work has indeed achieved a set of protective clothing, safety helmets, oxygen supply systems, etc. and their associated safety equipment. According to the professional division of labor, each fire truck can carry five to six people at a time, including the driver. Some soldiers are for firefighting. One water gun requires about three people (one person to manage the pump truck; one person to smooth the hose and assist the water gun operator; one dedicated water gun operator); some are for search and rescue. Two people form a team, and two teams require four people. The result should be obvious that there is a shortage of manpower. In contrast, let's take a look at the situation inside the building. In ordinary typical floors, there are two to three households on each floor, and even five or six households on each floor, which is also considered a very normal situation. Each household is roughly calculated as three people, and there can be as many as dozens of people on each floor. On some floors and in some homes, there are elderly people who are bedridden, sick people who cannot walk, pregnant women, and disabled people, etc. In non-typical residential buildings, the population is even more complex and numerous. There are also those commercial collective small partition-style office spaces, large and small stalls, berths, etc., and the crowds are extremely dense. In short, there is a serious imbalance between the number of rescuers and the number of people to be rescued, and the number of professional workers at the fire scene is very tight. What is particularly serious is that there is no self-rescue equipment of any kind on the scene.

[0004] Invention content: The specific content of this invention patent is a device specially used for high-rise civil buildings. When a fire breaks out, people are trapped in other rooms on the same floor. Even the lives of many people living or working on other floors above are also threatened by the smoke and fire. Because the smoke and fire in the corridor are too thick, the elevator will be forced to shut down due to the fire, and people can no longer escape from the fire scene through the corridor. While waiting for the fire brigade to come to extinguish the fire and rescue the trapped people in the room. With the help of the latest invention patent project ---- the simple escape device for self-rescue from the window, which is always prepared in advance somewhere in the house (under the bed, on the top of the cabinet, behind the closet, etc.), the trapped people in the room and nearby windows can escape and escape from the dangerous and life-threatening fire scene as soon as possible, thereby realizing the specific measures for self-rescue. In this way, the people in distress can get out of the dangerous situation of smoke and fire as soon as possible. When the fire truck arrives, the firefighters can concentrate on extinguishing the fire on the spot. No longer need to put out the fire while going door to door to rescue the trapped people in the fire scene, so as to put out the fire as soon as possible and minimize the property loss of the people. The device of this invention is specially based on the various modern structures used in most of the existing residential buildings in the southern and northern regions of the domestic modern society, and the single and double-layer windows of various styles assembled by wood or plastic steel materials are used in different directions. Whether it is facing the east, west, south or north, there will always be one or two windows facing the direction of the sudden fire scene. The new device we invented is suitable for installation and use at windows of any direction. The installation of our new device is based on the original window size of each household. It does not damage the original window or any part of the window frame. It only needs to remove the screen window and the anti-theft window (there are not many anti-theft windows in high-rise civil buildings). As long as you are facing the direction of the fire, away from the danger of the fire, and are not exposed to the smoke of fireworks, it is feasible for the windows in your home to be safe and strong. Even if the family is a small one-room apartment with a small population, they can still use this invention to achieve the goal of self-rescue and escape. You can completely avoid the direction of wind and fire and hide in a window where there is no fire damage, so as to avoid the fire in the same room but in a different direction; that is, you face the window without fire. You walk to the window with your back to the burning fire to implement the bracket; go out of the window; enter the hanging basket; operate the hanging basket to start sliding down; land safely, and the self-rescue is successful. Of course, it is necessary to remind the users of this invention here: before you choose to use this latest window self-rescue simple escape device to complete the escape at the window, it is best to know in advance whether there are too large protruding obstacles outside the windows of each household on the corresponding floors downstairs at the window that you need to use urgently, which will block the sliding operation of the hanging basket we are about to take.Some families like to install flower rails, pipe racks, etc. outside their windows, and put some bottles, cans, and sundries. Small objects should not be a big hindrance; but those windows that are supplemented with various large color steel balconies are generally expanded to a wide range of sizes. It is very likely to hinder our escape and cause obstruction to the vertical descent of our device. We must pay more attention to avoid scratching and bumping. It is not right to hurt anyone. It is best to avoid using this type of window to avoid affecting our emergency escape and rescue in an emergency. However, if the obstruction point is not disturbed by fireworks and really hinders our escape route, we may as well try to take the "borrowing road" to escape from the fire. Of course, our latest invention of the simple window escape device only needs to use the existing state of the original window to directly install the device, and the width and narrowness are flexibly adjusted according to the actual size and style of the window. In order to prevent the quality of some window frames from being problematic and difficult to bear their actual load weight. We also make full use of the adjacent window sills in three directions; the plane, facade, corners and window sills of the brick wall; with the same amount of steel strips, angle steel, round steel and other auxiliary materials, with different postures of the inner wall of the window, three or four all-round directions, turn when encountering bends, hook when you can, pull when you need to, give full play to the close bonding force of the window frame with three walls, with Φ10 diameter thick screws, hexagonal nuts, butterfly nuts for all-round follow-up screwing, and even the most common steel nails on the wall, firmly fix the steel triangle bracket, and meet the fundamental demand of limiting weight to the greatest extent. The structure of this device is not complicated. It is a central triangle bracket structure composed of flat and square galvanized steel pipes with a wall thickness of about 3 mm and a specification of 50*100 mm, which are more common in the market. The length and shortness of the main skeleton inclined beam main bar need to be determined by the position of the selected window bright grille frame on the whole window. The bright grille frame is located above or below the full window, and the positioning is adjusted. Then use angle steel, strip steel, round steel and other auxiliary materials with the same load-bearing capacity, and use six to ten millimeters thick threaded screws to punch holes and connect; the non-fixed connection positions are fixed and positioned with single and double-way, disc-shaped and hexagonal nuts. For the connection positions that need to be fixed, just use electric welding to weld them. In order to adapt to the good matching of walls, window sills or windows of different shapes and sizes. Achieve the maximum degree of frame and frame combination. After the device is used on the spot, it can be completely disassembled and recovered, and continue to be stored in the family room (Note: This device is not suitable for storage in underground warehouses and other very unusual places.) It is easy to move and not in the eyes of the family room, so as to prepare for the next possible emergency, so as to be prepared. However, the most important on-site material is the pure white steel multi-strand fine wire twisted steel cable, which has just become popular in the market in recent years.Then, we developed and designed a new type of special linear material that is practical and fully meets the actual needs of the fire scene. It is not afraid of fireworks; it is oil-free, paint-free, and corrosion-resistant; its rigidity is smoother than ordinary steel cables. Its greatest advantage is that it does not need to worry about being rusted and broken after being stored and used for many years; it does not need to be fully oil-immersed to enhance its anti-corrosion and lubricity. It completely abandons the major defects of chemical fiber ropes that melt when exposed to fire, ordinary carbon steel wires that rust and break easily, and short service life and storage period. Our device uses pure white steel filament twisted strands. Its current market sales price is not too high. The full-wheel white steel thin rope with a diameter of about three millimeters has a market retail price of no more than 1.5 or 6 yuan per extended meter in Shenyang. In this way, the manufacturing material cost of our new invention patent project will not be too high. It is extremely conducive to the popularization and promotion of a large number of cities across the country.

[0005] Our latest invention patent project - a simple escape device for indoor personnel in urban civil buildings during high-rise fires. Its basic structure consists of two flat and square galvanized steel pipes with a length of 1,200 mm, a wall thickness of about 3 mm, and a diameter of 50*100 mm as the main frame beams. The two sides of the upper horizontal frame of the open window of the resident's home; that is, the position of the outer frame edge at the two 90-degree corners at the upper end of the window, are used as the flat surface of the two end faces of one of the two main frame beams (facing the direction of the room). The other end faces the direction of the outside of the building. Note: The bottom line of the horizontal inner edge of the upper beam of the window frame must be consistent with the horizontal line of the bottom edge of the end face of the bottom plane end of the two steel main frame beams (that is, the ends of the two steel main frame beams, one left and one right, directly against the upper edge of the window frame). Then, place the bottom planes of the two steel main frame beams face to face along their extension lines. The depth of the flat contact must be at least 40 mm, and a strip of steel with a thickness of 3 mm and a width of 50 to 60 mm should be fully welded. Also note that the strips are welded flat against one side of the beam. The strip on the left beam is welded to the right half of the bottom plane of the left beam; the strip on the right beam is welded to the left half of the bottom plane of the right beam. After the strip is welded, the longitudinal end of the steel main frame beam is just against the outside of the window frame; and the strip in the same direction welded on the lower plane of the main frame beam replaces them and extends horizontally into the window. As for the length of the steel strip, it should be based on the thickness of the material of the window frame, plus the size of the reserved size that is enough to exceed the thickness of the wall at the top of the window frame. When it meets the corner of the wall, it must be bent upward at a 90-degree angle, so that the steel strip is along the wall, ensuring that it can hook the length of the main wall facade of the room. Finally, this is considered to be the appropriate length. However, at present, it is temporarily impossible to determine whether the household has a single-layer or double-layer window frame, a normal wall with a thickness of about 120 mm, a small narrow frame window edge, or a large-scale floating window with an inner width of about 1,000 mm. In the case of a wide and bright window sill, it can only be temporarily determined as the thickness of the outer window frame material, and a perforated steel strip with a length of about 30 mm and a Φ10 coarse aperture as a backup point for welding. Once the accurate structure is determined and the data is measured, a perforated steel strip with a Φ10 coarse aperture that fully meets the requirements must be added according to the actual scale. Then use the same diameter screw and hexagonal nut to connect to complete the complete matching of the above positions. The reason why a Φ10 thick diameter hole is left here is that in our careful setting, this position is the foundation of the steel beam, and it is necessary to specially reinforce an angle steel trip beam to stabilize the plastic steel window frame. The angle steel trip beam has two holes, each located at the two ends of the bottom plane of the angle steel, with the same width as the inner edge of the window. And it corresponds to the two holes with steel bars that have just been welded, one on the left and one on the right side that have just been inserted into the window.The facade of the angle steel is flat against the facade of the upper horizontal frame of the plastic steel window, and the end of the triangular main frame beam outside the window is tied. After the thickness of the total space occupied by the window frame, the shape of the window wall and other dimensions mentioned above are finally determined, the strip steel strip welded to the end of the aforementioned steel main frame beam is stacked together in three layers, and fixed with hexagonal short rod screws of the same diameter, and three butterfly nuts are used to position. With this hole, the inner end of the main frame beam is connected to the upper window frame, the horizontal angle steel and the main wall at the upper end of the indoor window frame as a whole. As you can imagine, it should be considered "unbreakable", right? Next, at the other end (outward side) of one of the steel main frame beams, that is, at the center line of the upper plane of the 100 mm wide tube in the horizontal direction of the flat tube end of the main frame beam, return to the center of the intersection of the two points with a length of 30 mm inward, and punch a Φ10 diameter through hole to be used as a hole on one side of the outer ends of the two main frame beams; at the same position of the front outer end of the other main frame beam, the same method is used to process it in the same way as mentioned above, and another Φ10 diameter through hole is obtained. The double through holes are specially used for the key position holes to connect the pair of main frame beams together. After drilling, set aside. We take another 400*400 mm galvanized steel plate with a thickness of 3 mm, draw the horizontal center line of one direction of the center of the square, and clamp it on the table clamp according to the line position (that is, divide the whole square from the middle into two rectangles of equal area). Using the drawn center horizontal line as a turning point, bend the other half of the galvanized steel plate at an angle greater than 120 degrees. Then we took the galvanized steel plate that had been folded into an "Λ" shape, similar to an arrow shape, and separated the two edges of the steel plate that stretched outward (its two legs), and clamped them on the table clamps again, and beat them in the opposite directions of the earlier folded corners, and folded them back again with force; until it was folded into: from the horizontal end of the whole iron plate, the upper part is arc-shaped on both sides, and there is a certain amount of downward extension surface at the bottom tip, and it is a red "heart" shape with an opening. The opening width at the bottom of the "heart" shape cannot be less than 50 mm at the narrowest two edges. Such a process of beating and folding is just to make it harder and less deformed. In fact, the previous tossing is exactly the whole process of making the head clamping slot grille at the top of the two beams of our steel triangle bracket.Then, we turn the head clip slot grille with the closed end facing outward and the 400 mm long horizontal large opening end facing inward; from the current state, we are facing a closed end, a three-sided open grille slot plane with interlayers on the top and bottom (it may also be a bulging arc in the upper half and a rectangular plane in the lower part), we can start from the left edge of the rectangular part at one end of the galvanized plate plane, and measure a distance of 100 mm to the right end as a point; then start from the edge near the bottom (the lowest straight edge), and measure the intersection of two points with a width of 50 mm above the closed round head; take the center point to the vertical bottom of this plane grille slot body, and drill a through hole with a diameter of 10 mm on the upper and lower grille slot flat surfaces (both layers of iron plates need to be drilled through). And the other side of this grille slot body, that is, the same corresponding position on the right end, also needs to be reversed in the same distance and size, and then drill a through hole with the same diameter. The two through holes are symmetrical, one on the left and one on the right, and they are connected to each other from top to bottom. In this way, the special head of the triangular bracket structure of our new device is also completed. With it, we can use two Φ10 thick diameter screws with a length of more than 100 mm to connect the head grille with the outer ends of the two square tube main frame beams, one hole and one rod, horizontally. The two fixed hexagonal nut ends with rods are the lower ends, and the upper ends are tightened and positioned by two butterfly nuts. In this way, our new invention patent project-the window self-rescue simple escape device, has a certain scale. However, there is an important link that cannot be forgotten. We need to consider the formation of the steel triangular bracket and the positioning of the beam. Only when the two partners are combined into one place can the triangle be stable, so let's start working to welcome the other half of the triangular bracket structure. First, determine the position of the other half. Let's start from the center of the outer end of the 1,200 mm long main frame beam: For the first item, we have to turn the main frame beam 180 degrees so that its original reverse side is facing up. This is because the work to be done is all below. We have to determine the size and position from the top of the main frame beam forward, starting from the edge, subtracting the 80 mm length occupied by the head clip slot grille, and then reserving a 50 mm long distance as the location of the assembly work area. That is, the direction from the outer end of the main frame beam back to the building window, measure 130 mm and mark it. Take a 3 mm thick and 50 mm wide flat strip, and cut it into 100 mm long sections with a toothless saw or other type of cutting equipment. A total of eight strips are enough. Each short strip of steel needs to be cut manually or with other types of grinding tools to remove three millimeters of width from one side of the cut short strip (one hundred millimeters long) in the longitudinal direction (to make it narrower, either the left or right side is fine). Only one side of a short strip needs to be removed.Then, measure 30mm at one end of each short strip in the longitudinal direction; leave 70mm at the other end (that is, the 30% to 70% ratio of the entire length) and bend it upward as a whole. The bending angle is about 30 to 35 degrees for four short strips; and about 35 to 40 degrees for the other four. Then, we need to put two short strips of bent steel with the same curvature side by side in a group; follow the principle of small angle in front and large angle in the back, and the two groups of large and small angles are positioned at a distance of 120mm (the front and rear groups of support clips are specially designed to meet the needs of changing the main frame diagonal beam from long to short). After the corners are folded and the edges are ground, the two groups of short strips of steel are welded flat on the two main frame beams, one on the left and one on the right, with the endpoint as the most forward horizontal line, at the marked position just drawn (i.e. the 130 mm position measured earlier). The marked point is the center of the pipe plane; the two welded short strips of steel are exactly at the center of the back plane of the main frame beam. The starting welding point of the second group is 120 mm away from the starting point of the previous group. Both groups of short strips must be welded horizontally and vertically, with tight seams, otherwise it will be difficult to enter the main inclined beam pipe mouth. After this marking position is given an important mission, the entire main frame beam can be completely turned around. Two groups of short strips of steel (each group consists of two short strips) are welded on the bottom plane of each main frame beam. Note: You should also measure 35mm upwards from the lower end of the 70mm long part of one of the reserved steel strips (after bending at a ratio of 3:7, the 70mm long end is hanging down), and drill a Φ10 through hole at the center of the width of the single steel strip. Drill one hole in each of the front and rear groups on the same side, the same position on the same side, and a total of four holes. From a responsible perspective, we also need to flatly weld a Φ10 hexagonal nut on top of the through hole. The center of the hole of this nut must correspond exactly to the center and angle of the hole on the welded steel strip. The rod must be concentric and not misaligned, because this position is the most difficult position for the triple rod. This will be the most important part for the entire triangle support to combine the horizontal and oblique steel beams into one. It is related to the safety and stability of the entire triangle support. The three-millimeter-thick square tube wall or the same short strip of steel may not be able to bear the heavy task (too few threads and no strength). Here, a standard nut is specially reinforced to carry their total weight to make it strong enough. Before the upper and lower parts of the triangle support are connected and supported, we must insert the front end of the main oblique beam of the triangle support in advance and weld it side by side on the lower plane of the steel main skeleton beam, which is composed of two short strips of steel bent and combined, on one set of support buckles.After the two sets of components, the upper and lower parts, are pushed and inserted into place, we use the gap at the pipe mouth to find the corresponding position of the upper port of the main inclined beam and the preset through hole on the support buckle (because it is only about 40 mm away from the upper port of the main inclined beam, it should not be a problem), and use an electric drill with a Φ10 diameter to drill through the corresponding position of the single-layer pipe wall at the lower plane of the upper port of the main inclined beam. We use a screw rod with a fixed hexagonal nut to connect and tighten the newly opened through hole, the hole on the short strip of steel strip that is folded into a downward bending state, and the hexagonal nut on its back (if the length of this screw rod is too long to be attached to the edge, a thick nut of the same diameter should be added to the appropriate position of the screw rod to attach to the edge to increase the force). It is the connection point of the main horizontal and oblique steel beams of the triangular bracket, and it is also the core of the integration of the two partners of the triangular bracket structure and the stability of the triangle. It is also the most important core part of our newly invented device that must be stable. Of course, at this point we need to explain in detail that the triangular bracket main frame diagonal beam is made of flat and square galvanized steel pipes with a wall thickness of about three millimeters and a specification of 50*100 mm. This 1,800 mm long specific structure is actually composed of two parts if you divide it carefully. The upper part is 1,500 mm long, and the lower part is only 300 mm long. The front end of the docking interface is not much different from the main frame crossbeam except that the docking angle is slightly different. The fundamental difference lies in the short joint of the lower part. The length of the two main frame diagonal beams needs to be changed accordingly according to the position of the corresponding window grille frame, whether it is on the upper side or at the lower end. That is to say, a long grille frame of the window grid, installed at the window below the entire window grid body, needs to be supported by a 1,800 mm long flat tube main frame diagonal beam; and a whole grille frame of the window grid, installed at the window above the window grid body, because the position of the steel triangle bracket is lowered as a whole, the original size of the main frame diagonal beam is too long, and the short joint on the main frame diagonal beam needs to be removed (that is, two Φ6 diameter long rod flat head connecting screws and 300 mm long short pipe joints need to be removed), and replaced with a single 1,500 mm long square tube main frame diagonal beam to match it. It is also regarded as the same as this group of windows without grille frames. Other aspects remain unchanged. And such changes in length and shortness, fundamentally, prove that our new device can adapt to the specific manifestation of various types of window structures. Of course, due to the rapid development of my country's economic construction in recent years, the changes in various regions, whether in the entire building type, its window type structure or building materials, are very huge. The various window types with different sizes that followed are also varied. Faced with such a complicated situation, in reality, we advocate adapting to local conditions and being flexible. We fully utilize the working principle of this invention patent project, the simple and practical structure, the simple and convenient installation method, and the wide range of applicable contents of the new device.The equipment manufacturer should take the actual window types and sizes of the families who need the new invention as the new goal for completing the equipment processing work. We should try our best to treat individual cases specially and solve the practical problems in the actual customer applications. We should make every effort to ensure that it can be used at critical moments and meet the needs of users at the critical moment of life and death. In order to ensure that all existing civil high-rise building window frames have the corresponding bearing capacity to ensure the safety and stability of our new invention, we have also specially added a complete set of window stabilization systems and steel frame reinforcement systems for the triangular bracket structure of the above-mentioned new invention. To strengthen the new invention in actual use, try to reduce the reliance on the original wooden or plastic steel window frame load. At the same time, comprehensively strengthen the stability and impact resistance of our new triangular bracket device, so that our newly invented simple fire escape device has stronger safety and practicality. We first used 30*30mm wide national standard angle steel materials, matched with some Φ10 diameter round steel auxiliary materials, one layer inside and another layer outside, and welded a Φ10 diameter thick round steel vertically at intervals of 100 mm, directly welded to the two upper angle steel strips that face each other and buckle together with the corners facing down; the two lower angle steel strips are back to back and at the same angle as the bottom corner of the window frame, and are in the shape of a "mouth" (the upper and lower angle steel strips on each side are combined together to form a "mouth" shape). The angle steel strips on both sides of the inside and outside are across the plastic steel window frame that is hot-glued together, and Φ10 diameter holes are drilled at both ends of the facade; in this way, around the lower end of the outer side of the window with a large mounting load, and at multiple connection points related to the horizontal and vertical frames at the base of the triangular bracket, the internal and external double-sided reinforcement is carried out. The window frames that do not have cement wall foundations as support in their individual parts are firmly connected together with steel clips, the plastic steel frame is wrapped with steel, the Φ10 diameter thick threaded screws penetrate the steel frame horizontally inside and outside, and the two-way butterfly nuts are screwed firmly to fix it. Of course, for those parts where glass is installed at the lower end of the window (that is, the lower end of the window is equipped with a window grille frame, and the main frame diagonal beam is 1,800 mm long), we use the window screws to cross the frame, and the angle steels to cross the upper and lower end frames to make a single row of screws for reinforcement; for the window type without glass installed on the lower floor (that is, the lower end of the window is not equipped with a window grille frame, and the main frame diagonal beam is 1,500 mm long), we use the angle steels at the upper and lower ends to clamp the frame columns, and the upper and lower ends are penetrated by double-layer force-added clips, which are more firmly integrated and handled, which should be considered foolproof. We call it a window frame splint. This is our window frame stabilization system. Of course, this is not the end.We also fully utilized the two most reliable and powerful ends of the 90-degree angle formed by the angle steel at the bottom of the steel clamp outside the window and the cement window sill outside the window. We deliberately extended the two ends of the angle steel a little more (each end is long enough to weld a Φ10 diameter thick screw rod). In this way, we added a Φ10 thick screw rod with a length of about 50 mm and a threaded thread at the left and right positions. When the main inclined beam of our flat tube steel triangle main frame is assembled at the upper end, we also welded a Φ10 thick hole iron angle code on the left and right side elevations of its lower port. Then, we can "match the main inclined beams" and insert them into the root of the window sill with the angle code holes at both ends, and weld them on the Φ10 thick screw rod on the angle steel, and then match them with special butterfly nuts to tighten them. So far, although the triangular structure of our latest invention is simple, the tail end of its crossbeam is in a wall-hugging state; the lower end of the inclined beam is in a clamping state with the inner and outer window frame roots, and the window frame roots are clamped in the cement wall. This is the most powerful three-support platform for the entire window. In this way, the design structure of our new invention is heavy, and it is also the most powerful, and it should be the most trustworthy. There is another point that needs to be supplemented here: when the 1,800 mm rectangular tube main skeleton inclined beam is changed to 1,500 mm in length, it only needs to remove the 300 mm long short joint connected to its lower end. Then someone will definitely ask: If you remove the short-circuit part below, will the new interface that appears be unable to continue to connect downward? Friends. This is not the case. The new design of our project also takes this into consideration. If you really want to be able to adapt to all kinds of different window shapes, you must be able to change. First, when making the entire triangular support structure, the main material is the 50*100mm diameter flat and square galvanized steel pipe for the main frame. When cutting the material, we must follow the following rules: the horizontal beam is 1,200mm long; the diagonal beam is 1,500mm plus a 300mm short pipe, which is the most economical way to save materials; the 1,800mm long overall diagonal beam is made by connecting these two parts. We took a 3mm thick and 50mm wide steel bar and cut a short strip with a total length of 276mm. Then we measured a length of 44mm from one end and marked it.From this marked point, the strip is bent horizontally as a whole into a state with a 90-degree angle; then, it is necessary to measure the length of 94 mm from the corner of the 90-degree angle that has been folded; the marking line should be marked again here, and then the strip should be marked with this new mark again, and another 90-degree angle should be folded twice in the same direction; then, from the new position of the corner mark, a distance of 44 mm in length is measured again along the extension direction, and a new mark is drawn again; from the new mark, another 90-degree right angle is folded again according to the previous sequence, and the remaining last section is exactly 94 mm in length; all three corners are folded into 90-degree bends, and the remaining two ends touch each other again, still a 90-degree angle. In fact, this is folding a rectangular ring. The four corresponding sides are equal to each other, plus four 90-degree angles, and it will definitely take shape. That is, two 44mm and two 94mm are exactly 276mm long. Its ring size is just slightly smaller than the original 300mm total length of the flat and square steel pipes. Then, we have to first weld the two ends that are not connected together together by spot welding at the vertical seam inside the pipe mouth (if you want to be convenient, directly weld at the outer vertical seam of the two ends, which is easy to cause the weld to be uneven and unusable). Then, use a hand-held tool that is not afraid of heat (such as iron pliers with sleeves, etc.) to clamp one end of the edge, and lower the other end of the port in a rectangular shape into the upper flat end of the 300mm long short pipe joint of the main inclined beam square tube. It must not be fully inserted. The best insertion depth is half of the 50mm wide steel strip (about 25mm wide). It is better to be larger than smaller. Then, weld the straight line gap that is closely attached to the edge of the upper end of the short pipe (because it is a reservation made after the length is measured, it should be a tight joint. If there are any unevenness or obstructions, they can be removed with a hand grinding wheel), and weld it all around to make it firm as a whole. The lower end of the 1,500 mm long steel pipe main inclined beam should also be able to easily fit into the flat and square inner sleeve that is specially reserved for it, and the other half is made of a short strip of steel and is folded into a smaller circle. However, just putting it on the outside for a circle is not enough to achieve ideal firmness, and it is still necessary to tighten it with special screws to be sure. In this way, when we need a long connection, we specially select two lengths of more than 110 mm, one for each main beam; one end is a fixed hexagonal nut, and the lower part is a common round rod with a screw thread of Φ6 thick diameter. A through hole is punched at the lower end of the outer side of each flat and square tube main inclined beam, about 15 mm from the mouth line, and in the middle of the inner ring sleeve formed by the short horizontal 3 mm thick strip of steel hidden inside. It directly penetrates the four layers of the tube wall at the left and right ends, and is tightened by a manual butterfly nut from the other end outside the main tube wall. Only such a design and installation can be called reliable.When the main inclined beam of the steel pipe is shortened for use (when the length is changed from 1,800 mm to 1,500 mm), put aside the short pipe and the attached screw, replace it with a Φ6 thick flat head short screw, use the original position and original diameter of the two ends of the pipe wall, and then stick one on the left and right ends, one of which is a Φ6 thick round screw hole, and the bottom angle plane is an iron angle code with a Φ10 thick round hole (the specifications are exactly the same as the original angle code at the lower end of the short pipe). The left and right sides of the Φ6 thick round hole are fixed with flat head nuts on the outside, and the butterfly nuts of the same diameter are in the lower end of the steel pipe main inclined beam. The Φ10 thick round hole at the bottom of the angle code is re-completed with the outer window sill, and the Φ10 thick screws that are preset at both ends of the angle steel and tilted upward are positioned, and the butterfly nuts are tightened after perforation. This can be called "shift connection". In fact, there is another additional link that needs to be explained in detail. That is to further stabilize the entire triangular support structure system, and at the same time to enhance the personal safety of window operators and window escapers. We also added a full-steel structure "stepping platform" at the position between the lower window sill of the selected external escape window and the escape hanging basket. We carefully thought about it: otherwise. The narrow external window sill is only about 200 mm wide, and it is very difficult to stand on one foot. It is very unfavorable for the installation of equipment;. Adding this stepping platform allows everyone to have a foothold after stepping out of the window. It will also make everyone who wants to escape from the window closer to the suspended hanging basket, which is convenient for everyone to ride, and will make people riding it in the air feel quite safe. This stepping platform structure is half-sat on the window sill outside the window, and is in a semi-empty state. The entire platform body will have a slight change in width and narrowness along with the span between the two steel main inclined beams. It is formed by welding two sets of national standard angle steels with corresponding mouth surfaces, two of which are 650 mm long (disposed diagonally upward) and the other two are 600 mm long (horizontally placed at the lower end), and Φ10 mm thick round steel. It is supported by the root of the steel main inclined beam and sits on the outer window sill. A Φ6 thick round hole can be punched at the end of the angle steel, and an iron angle code can be connected in the forward direction and hung on the angle code upright pole at the bottom of the main inclined beam. The two upper angle steels face outward, back to back, and are attached to the upper plane and inner side of the lower half of the two main inclined beams. Based on the side angle of the main inclined beam and its inclination angle, six Φ10mm round steel bars are welded vertically at the upper and lower ends every 100mm from low to high, one section higher than the other, and it ends after six sections. The footrest below is also made of Φ10mm thick steel bars arranged horizontally and sparsely at intervals of 100mm, welded horizontally on the horizontal end faces of two angle steels placed face to face and parallel to each other.At the outer end of the last one, add another round steel bar of the same diameter and close together, diagonally forward and upward, slightly higher than the sixth round steel bar of the same diameter at the outermost end by about 5 or 6 mm, and spot weld it firmly (according to experience: this method can play a role in preventing stepping into the air and reminding you to ensure safety.). Then, take out six short strips of 50 mm wide and 180 mm long; each strip is measured from any end of the strip in the forward direction by 50 mm, and then bent downward to a 90-degree angle from here. Divide the short strips of steel that are hooked down after the angle is folded into two groups, each with three strips; place one strip at the upper and lower ends of the two angle steels buckled on the main inclined beam, and add one strip in the middle, and arrange them evenly at intervals; try to avoid the vertical round steel strips that have been welded on the vertical surface of the angle steel and have been welded properly. Hang the hooks of all the short strips of steel downward, with the flat ends facing the opposite direction, and fully weld them on the bottom plane of the back plane of the angle steel facing downward. The short strip of steel after the downward bending, the hook part and the lower facade of the angle steel facing outward at the other end are like the "tiger's mouth" shape of a human hand, and are buckled on the "∏"-shaped three-side orientation structure at the "back and shoulders" of the steel main inclined beam. It is always supporting the lower half of the steel main inclined beam, which is stable and firmly bears the weight of the outward expansion platform, and firmly supports the two main inclined beams that bear the load, and cannot swing left and right at will. Therefore, it is enough to become the title of the "steel frame reinforcement system" we added. This detailed introduction, like a treasure, has almost connected the overall structure of the triangular bracket into the house. Such a dual-performance stabilizing effect cannot be replaced by any other type of device. This not only brings stronger safety to the newly invented equipment as a whole; but also makes people who are about to use and ride the new equipment believe that this is the real safety equipment, and this is the "safety basket" in its true sense. Next, I will introduce the last and most important part of the equipment in this device in detail - the safety hanging basket. The composition of the hanging basket adopts the principle of using local materials, making full use of the most ideal modern new special steel material in our mind - pure white steel filament multi-strand twisted steel cable, as the main linear material; using the more common small steel cable twisted buckle on the market to make knots; weaving a water drop-shaped net bag with six warps and four wefts, with a dense bottom and sparse top shape. It is hung on a small, anti-slip gear-type curved hook lifting hook (most of these main parts are purchased parts); the lower end sits on a hollow metal round box made of a round, four-ear buckle, galvanized steel plate with a diameter of more than 400 mm and a thickness of 3 mm. This box is the storage box of the white steel sling. The shoulder part of the outer circle of the box is evenly distributed with a number of fully enclosed steel network load-bearing hanging rings welded by Φ6 diameter thick steel bars. Inside the hollow metal box is a winding wheel with an inverted white steel cable, which is composed of a Φ10 thick-diameter steel triangular support and a 60mm thick wooden cable core.The shaft core of the wheel uses a pure brass hoop to replace the bearing structure, which enhances the overall durability of this equipment. The lower right side of the box is the entrance and exit of the steel cable; the front of the box is equipped with a guide pulley and a winding guide pulley with a certain elasticity that can swing left and right. The steel cable outlet outside the box is also locked with a diamond-shaped steel cable controller with a handle, which directly controls the exit or stop of the steel cable in the box. When your hand holds the handle at the rear end, the basket should still carry a certain weight before it slowly slides down; when you release your hand, the diamond-shaped controller will stop the basket immediately and the steel cable will stop coming out; if you put the pendant ring of the handle on the controller together with the handle, it will automatically slide the entire basket to the ground (but remember: a certain weight must be loaded in the basket). In order to give full play to the more powerful life-saving function of our new invention, we also specially installed a set of DC 6V small motors and exclusive batteries on the control box of this device. The wire storage box is equipped with a reel for reeling and reeling. The extended shaft of the reel and the shaft of the motor intersect on the outside of the box in the form of a trapezoidal gear. Every time we use the hanging basket, we can directly adjust the motor outside the box in the hanging slot to the bite position of the reel tower shaft, and then manually start the linkage mechanism between the motor and the reel, so that it can automatically realize the conscious reeling action of the DC motor driving the reel without heavy load and unmanned control. When the basket returns to its position, our main power control device will automatically cut off the main power supply above to stop the motor from rotating. That is, you can return to the fire window where the tripod is located again. If there are still people who have not escaped in the room, you can take the lifesaving hanging basket to escape for the second, third or fourth time. How precious and touching this is. It can be seen that small inventions play a big role; saving people from fire and water is heroic. Helping firefighters solve people's difficulties, everyone praises small inventions.

[0006] There is one more thing to note: In order to prevent some bad guys from using our new device to do bad things, we installed a red and yellow non-police light with a flashing siren on the top of the hanging basket (just like the safety warning light installed on sanitation sweepers).

[0007] Next, I will introduce the complete installation procedure of our latest invention patent project, the simple escape device for self-rescue from windows, to the experts in detail. First of all, we want to explain that after the design department of the manufacturer has officially completed the design of this invention patent project, the most important steel parts can be mass-produced first, so that the inventory reserve of the products can be done directly. For some special supporting parts, we should also make the most appropriate production arrangement according to the most common window types, patterns and styles of most high-rise buildings in the local area. We should also make the most comprehensive market survey, and transform our patent design ideas more directly into the latest products available to customers, so as to better serve everyone. Our manufacturer's reception department must understand the approximate pattern of the family room of the application customer, and patiently ask each customer for the actual size of the house type and window type. Those who cannot explain clearly need to immediately go to the home to measure clearly, so as to fully prepare the supporting accessories. All auxiliary materials should be based on the principle of "no bending when not in use; prepare holes before extension". There should be prepared nail holes at the end of the strip. For example: are the south and north windows sliding, inward-opening or outward-opening? Is it a "one-fixed-two-opening" type or is the window grille on the top or the bottom, etc.? Is there a floating window? You should know all these. Only in this way can you choose the materials accurately. Although it can be considered as a comprehensive consideration to avoid too many auxiliary materials for customers, you should also know that this is a very abnormal waste. It should be avoided as much as possible. When we live peacefully and leisurely in our own homes; some of us are busy working in the office in a very normal manner; perhaps at this time, when we suddenly smell a burst of odor in the air, we must find the source of the odor indoors and outdoors. If you find that there is a sudden fire on the same floor or on a floor downstairs, and the floors are close to each other, you must pay more attention to it. Don't panic first. After dialing 119 to notify the fire brigade to come and put out the fire, if you feel that the danger is approaching us step by step, we must make full preparations. First, we should pay attention to closing the door and all windows in the direction of the fire source, and do our best to prevent the fire from attacking our direction. Pay close attention to the temperature changes inside the corridor and the changes in the concentration of abnormal odors with the wind. Because some toxic gases are invisible, we should always understand and grasp the current wind direction and wind force outdoors, the possible direction of the fire, and make our most far-sighted choice - whether to escape from the south window bracket or the north window. Take action immediately when necessary. Then, take out the simple window escape equipment we have prepared long ago from the back of the closet, and move all of them to the window where the bracket action will be taken.The first step: In front of the window sill, the outer end of one of the 1,200 mm long steel square tube main skeleton beams should be connected to the triangular bracket head made of 3 mm thick steel plate, and the double-ply pulley system with an inverted triangle (the two ends of the plywood are reserved with a hanging directional pulley frame with holes at the same distance as the steel plate head). The four through holes on one side of the three main parts are placed at the bottom of the directional pulley triangle iron plate; the two layers of flat surface of the steel plate triangular bracket head, the upper and lower layers of the main skeleton beam square tube end are located at the top; a Φ10 thick diameter, no more than 100 mm long fixed hexagonal nut screw with the same diameter is connected. The fixed hexagonal nut end should be on the lower side, and all connected together by screwing through four layers of single-hole holes layer by layer, and the same diameter thick butterfly nuts and steel anti-rotation washers are tightened and positioned; it is best to use an ordinary adjustable wrench and butterfly nuts to add force at the same time, tighten the double screws, to ensure that there is no risk. At this time, don't forget to pass the end of the white steel sling through the hook groove of the pulley disk, tie it to the end of the small hook at the top of the hanging basket, and fix it in place; Step 2: Use the window frame clamp we added to reinforce the lower window frame, with a Φ10 thick diameter screw of no more than 150 mm in length (subject to actual on-site needs), four on the upper and lower sides, and cross the reserved holes on the angle steel to tighten them in opposite directions. Here is a note: If the selected window is a window type with a window grille at the bottom, there will be a glass window blocking the lower end; you can only use the dense full-position clamp frame of the upper beam to penetrate all the connecting rods, and tighten the butterfly nuts inside and outside in both directions. The lower end does not need to pass the connecting rods and does not need to move. The window type without window grille at the lower end of the whole window grille must be fixed with double-layer rods on the upper and lower sides. As for some apartment types with no frame to clamp on the upper layer, we can insert the movable window grille frame tightly, and clamp the vertical frame of the two leaves that are opposite to each other. It is strong enough with angle steel and round steel. The double-clamped two-way thick butterfly nuts with the same diameter are tightened inside and outside to position; the third step: the assembler must go up to the window sill and sit on the steel frame of the window with one foot inside the window and one foot outside the window. Since the "walking platform" installed at this time has not yet taken shape, the assembler must pay great attention to his own safety. Then, the outer end parts of the second triangular bracket beam must be assembled in an embrace-style manner; including the rod, the directional pulley triangle plate must be at the bottom, the steel plate head and the upper and lower clamps with the main frame beam square tube end at the top, the four holes pass through the second row of holes, and the butterfly nuts are tightened on the iron plate head to position. The two main frame beams are assembled successfully. After completion, take the first main frame diagonal beam close to the window (you must first figure out the matching length of the window grille frame and the main diagonal beam, and figure out whether to connect a 1,800 mm long diagonal beam or a 1,500 mm long diagonal beam). First insert its upper end into the corresponding buckle position on the lower plane of the beam on the side farther from the body, and take a short screw with a fixed hexagonal nut. This time, it is a four-hole connected through-rod. It must be completed in one go to avoid dispersion or falling off.In this way, the staff can lift all three connected main steel beams out of the window sill at once, otherwise, it will affect your next work. Then, you need to insert the lower end of the longest beam (it must be the main inclined beam) directly into the angle steel at the corner of the outer window sill closest to the frame, and connect them with the Φ10 thick-diameter screw that has been welded on the inner corner. You need to pause here and slow down. At this moment, there needs to be an angle steel waiting for you on the window sill. Next, you need to use a 30*30 mm angle steel with Φ10 double holes at both ends of the plane. On the inner side of the horizontal window frame in front of your head, hold the crossbeam with legs with one hand, and use the through holes on the steel strip that the end of the crossbeam is against to fit the through holes at the front end of the angle steel, and hang it securely with the hexagonal screw; then use one hand to hold the angle steel together with the steel strip (the total weight should be on the outer windowsill at this time), and with the other hand pull over the second crossbeam, and stick it to the upper corner horizontal frame. Once you turn the hands over, the positioning of the second angle steel and steel strip is completed. Hang the ends of the two main beams outside the upper window frame. (When inserting the screw here, you must pay attention: one end of the fixed hexagonal nut must be at the upper end of the screw hole, so as to facilitate the subsequent multiple connection and connection at this place in the future, and to facilitate the installation of other accessories.) First, stabilize the triangular bracket structure of one inclined leg; then use the other hand to screw the nut on the lower end of the main inclined beam that has only the angle code hole installed at the outer foot, but has not yet installed the butterfly nut. After this position is fixed, the overall structure of the triangular bracket is basically stable. Then you can turn your body around, and then insert the second main skeleton inclined beam into the buckle position of the upper crossbeam, and lower it to the hole on the angle code column on the other side, and screw the positioned butterfly nut again, and the whole large frame is basically successfully erected. Step 4: You can install the additional safety stepping platform we added. Then you need to adjust the width between the two main inclined beams in advance, buckle it stably on the lower back of the main inclined beam, sit on the outer window sill at the back, and hang it on the corner brackets at both ends of the bottom angle steel of the window. Don't forget to tighten the nuts at each position. The remaining work is to adjust the hanging basket so that people will feel safer and more comfortable when riding. Of course, no matter who can stand between the steel frames that are as stable as a platform, they will definitely complete their work calmly.

[0008] Description of the attached drawings: Let me now give a brief description to the relevant persons in charge in conjunction with the attached drawings. Figure 1 , are three-view drawings of the main structure of the tripod support of the new invention; Figure 1 ,---(I) is the main view; Attachment Figure 1 ,---(II) is the left view; Attached Figure 1 、---(III) is a top view; and Figure 2 , is a colorless simplified rendering of the new device in use; Figure 3, which is an exploded detailed diagram of the tripod structure of the main component of the new invention; including: Figure 3 、---(I) ; Attachment Figure 3 、---(two,); attached Figure 3 、---(three). We start from the attached Figure 3 、---(I) In the figure, we see the right side beam of one of the two main beams that is shown separately; the left side beam is basically the same as it. The only difference is that the short strip of perforated steel strip welded to the bottom of the beam tail is welded to the right half of the bottom of the beam tail; the right side beam is exactly the opposite, with the short strip of perforated steel strip welded to the left half of the bottom of the beam tail. Figure 3 ,---(ii.) is a main oblique beam 1,800 mm long; its special feature is that it can change from long to short. Whenever the window grille and lattice frame (common language calls it: window lattice; generally, the south-facing windows are large and have lattices, while the north-facing windows are small and do not have lattices) is at the upper end of the entire window, the window is naturally reduced in size. We regard it as without a window grille and lattice frame. We must remove the short joint at the bottom and use a 1,500 mm long oblique beam to match the existing, original-size horizontal beam. Therefore, the change of the length of the main oblique beam is a necessary result of the special circumstances of actual work. Appendix Figure 3 、---(Three) is the panoramic effect after the four horizontal and oblique main beams are combined together. Figure 3 , --- (IV.) From a safety perspective, we have designed a "window frame steel clamp" specifically for the bottom structure of the window frame to comprehensively enhance the strength and stability of various existing old window frames, so as to ensure that our newly invented life-saving device can play the most excellent and reliable performance during actual use on site. Figure 3 、---(V.) This is to enable our new invention patent project to play the most ideal safety and reliable rescue function in the future social production and life practice when danger is approaching. We professionally developed and manufactured the "slow-stepping platform" system specially used for the tripod structure equipment. In order to truly realize the new invention project and give full play to the new function. Figure 4 , is the most complex set of components in our new invention project - the hanging basket base and the steel cable retracting and releasing system. According to its various practical functions, it is properly arranged and arranged in a series of process expansion diagrams. Figure 4 、---(I) and Attachment Figure 4,---(ii) is the difference effect after the whole device is rotated ninety degrees. For the specific structure in the figure, we have used the simplest form of serial numbering to mark and explain the parts and functions of the whole device one by one. 1. The four bolts exposed on the top of the hanging shaft of the take-up and pay-out wheel; 2. It is a special DC motor for take-up; 3. Anti-movement pins specially set for the upper and lower box covers; 4. It is a reserved installation position hole for the cable operation controller; 5. It is the take-up and pay-out wheel shaft; 6. It is the copper sleeve of the take-up and pay-out wheel shaft; 7. It is the 'V' shaped hanging shaft of the take-up and pay-out wheel; 8. It is the outer baffle of the take-up and pay-out wheel; 9. It is the main shaft sleeve of the take-up and pay-out wheel; 10. It is shown from two angles respectively, and the supporting steel cable is an elastic 'Z' shaped transmission. Swinging pulley; 11. The hole for the steel cable to enter and exit the box; 12. The tower gear at the end of the reel shaft for taking up and releasing the wire; 13. The hanging battery in the box; 14. The manual switch for the electric motor; 15. The anti-collapse groove on the top of the box cover; 16. The guide pulley for the wire inlet and outlet in the box; 17. The red and yellow flashing warning lights; 18. The sliding hanging slot for the DC motor; 19. The upper and lower box covers are used as pendants for the rods and pendants for closing the box in four directions outside the box; 20. The support guide frame and the wire take-up wheel at the wire inlet and outlet are marked at two angles. Figure 5 , is a special device that explains the six-volt DC electrical circuit equipment and related automatic control structure used in the device in the simplest way. The figure only shows the principle and structural action of automatically cutting off the power when the hanging basket returns to its original position on the floor without load, which is enlarged at three angles. See Figure (F.) for details; and Figure (G.) is marked in the form of a simple circuit diagram. The reason why we have gone to great lengths to arrange this inconspicuous electrical energy device is that our small new device can still achieve the most ideal automatic control when there is no mains power at the fire scene. Attachment Figure 6 , is a general diagram of the manual control of the input and output of the cable, and emergency control. Figure 6 、---(I) ; Attachment Figure 6 ,---(II) is the main view and top view of the controller appearance; and the attached Figure 6 、---(Three) is in the attached Figure 6、---(II) (see the section attached: mm for details), they were subjected to a full set of internal structure section. The circular structure in the figure is the entire wire pulley group; and the two pairs of triangular structure installation parts are: the upper two pairs of triangular structure parts (a.) are connected to the elastic hand-held beam, and the middle pair of pulleys are wire roller brackets; the lower two pairs of triangular structure parts with screw holes (b.) are riveted to the controller shell as a whole, and the top has a friction plate to stop the rotating platform. When you want to start the hanging basket and start to release the rope to slide down, hold the hand-held beam and lift the two middle wire pulleys. Under the pressure of gravity on one side, the steel cable is slowly released from the seat box, and through the outlet (c.) and inlet (d.) of the line, the pulley rolls upward to transport the rope, and the hanging basket carries us slowly down. If we want to stop descending, just release the handle you are holding, and the pressure of the spring will press the pulley and the steel cable in the cable groove tightly against the triangular stop table with friction plates. This will immediately stop the outward delivery of the steel cable, and the hanging basket will naturally stop steadily. Just like mountain climbing athletes, holding the rope tightly, they will naturally stop descending steadily. We deliberately conceived and combined them in a dedicated controller, thinking that this will be more convenient for users of the new device. We have learned from the front and back structure of the handbrake and gear shift on modern cars, just as convenient as being installed in a box, which should make people feel very entertained. In addition, the reason why the control function of our equipment is specially arranged to be different is that our new equipment is to be used in special occasions. Some timid ladies will hold on to an object tightly when they encounter danger, no matter it is a living thing or a fixed object. Therefore, we follow the rule of special treatment for special situations and make the main controller a way to start the operation of the equipment by holding the handle tightly. When you let go of your hand, it will brake. When you hold the cable net with one hand and use the other hand to get something, you can first hang the ring on the grip with the handle on the beam. At this time, you don’t have to worry about it. Just do whatever you want, and it will go down steadily by itself. In case of emergency, we can also use the emergency brake device, see Figure (e.) for details; press it all the way down to control it. The two closed gates obey the command steadily and stay where they are. It is truly safe, practical and secure. Attachment Figure 6 , --- (III) is the entire structure of the cable controller. From this tight internal structure, we can see that we have set up a multi-level guide wheel and brake system, which will make the entire transmission process safer, smoother and more reliable. No matter how tense or dangerous the occasion is, don't be afraid. Stop when you want to. Go when you want to go; until it lands safely and smoothly, then completely stop the operation of the hanging basket.
