Technical Field
[0001] The utility model relates to the technical field of escape ladders, in particular to an anti-water accumulation type outdoor escape ladder. Background Art
[0002] The outdoor escape ladder, also known as the fire escape ladder, is a building facility that serves as an escape route in case of fire. The outdoor escape ladder is installed on the outside of the building in the form of a welded iron frame. On the one hand, it is light and will not constitute a burden on the building structure. On the second hand, it is installed outdoors and will not occupy indoor space. On the third hand, escaping from the fire outside can avoid the chimney effect.
[0003] For example, the public document with application number 201710170000.X discloses an anti-skid pedal for an outdoor escape ladder. The anti-skid pedal for an outdoor escape ladder can improve the safety of the outdoor escape ladder. The pedal body is composed of a base plate and an anti-skid grid composite plate that are connected and fixed to each other. The anti-skid grid composite plate has anti-skid properties, is not easy to accumulate water, and is not easy to slip when stepped on. However, the pedal used in the outdoor escape ladder is flat as a whole, and both ends are directly fixed to the ladder frames on both sides. When climbing, people can only open their arms to hold the vertical ladder frames on both sides to apply force, and the vertical ladder frames are easy to slide down when manually held, and the flat pedal is not convenient for manual holding to apply force. Therefore, the overall setting shape is not convenient for manual climbing, making climbing more inconvenient and affecting the climbing speed. In addition, the flat pedal makes the center of gravity of the person stand vertically downward. If the person does not hold the vertical ladder frames on both sides firmly and the body shakes, it may cause the center of gravity to tilt backward, thereby causing the person to fall backward, affecting the safety of climbing.
[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-water accumulation type outdoor escape ladder is proposed. Utility Model Content
[0005] The utility model aims to provide an anti-water accumulation outdoor escape ladder to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-water accumulation outdoor escape ladder, comprising a fixed frame, an extension frame is arranged on the front side of the fixed frame, and a climbing mechanism is arranged in the middle of the surface of the extension frame and the fixed frame, and the climbing mechanism includes a fixing piece fixedly installed on the opposite side of the outer surface of the fixed frame and the extension frame, and a grip rod is fixedly installed on the opposite side of the fixing piece, and the same pedal is fixedly arranged in the middle of the opposite end of the grip rod, and a groove is opened on the surface of the pedal, and the upper part of the surface of the pedal is arranged as an inclined surface inclined toward one side of the wall, and the groove is also opened on the inclined surface.
[0007] Preferably, a slide groove is provided on the front side of the outer surface of the fixing frame, and a T-shaped block is fixedly installed on the upper rear side of the surface of the extending frame.
[0008] Preferably, the T-block slides through a slide groove located inside a fixed frame, and a cable is fixedly mounted on the upper end of the T-block.
[0009] Preferably, fixed pulleys are rotatably provided at left and right corners above the inner surface of the fixing frame, and a connecting rod is rotatably provided at the middle of the rear side above the outer surface of the fixing frame.
[0010] Preferably, both ends of the connecting rod pass through the fixing frame, a tightening wheel is fixedly installed inside the fixing frame, and the upper end of the cable is overlapped from above, passes around the fixed pulley and is connected to the tightening wheel.
[0011] Preferably, a hand wheel is installed on the right side of the surface of the right side converging wheel inside the fixing frame through a cross bar penetrating the fixing frame, and positioning holes are evenly distributed around the cross bar penetrating the fixing frame.
[0012] Preferably, a latch is slidably provided on the surface of the hand wheel, and the left end of the latch is located inside the positioning hole.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model is convenient for manual gripping, force application and stepping through the arrangement of climbing mechanism, fixing parts, gripping rod, stepping pedal and groove, and can also prevent people from falling backwards and slipping due to stepping on accumulated water, and increase the friction force when stepping on to a certain extent, so that the escapee can climb and escape more conveniently, safely and stably;
[0015] 2. The utility model adopts the arrangement of the slide, T-block, cable, fixed pulley, connecting rod, retracting wheel and hand wheel. When the floor is high, the extension frame uses its own gravity to expand downward along the slide under the limit of the T-block, thereby extending the length of the entire escape ladder to adapt to the higher floor interval. The hand wheel is used to drive the right retracting wheel to rotate. Under the transmission of the connecting rod, the left retracting wheel will also rotate to reel in the cable, thereby folding the extension frame and the fixed frame to reduce the length of the escape ladder and prevent thieves from using the escape ladder to climb between floors and residents;
[0016] 3. The utility model provides positioning holes and latches. After the hand wheel has completed winding up the cable, the latch is inserted through the hand wheel into the positioning hole at the nearest corresponding position to fix the hand wheel, thereby positioning the winding wheel. This prevents the extension frame from falling and unfolding due to its own weight when the escape ladder is not in use, making the folding of the fixed frame and the extension frame more stable.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figure 1-Figure 4 As shown, an anti-water accumulation outdoor escape ladder includes a fixed frame 1, an extension frame 2 is arranged on the front side of the fixed frame 1, and a climbing mechanism 3 is arranged in the middle of the surface of the extension frame 2 and the fixed frame 1. The climbing mechanism 3 includes a fixing member 301 fixedly installed on the outer surface of the fixed frame 1 and the extension frame 2 on the opposite side, and a grip rod 302 is fixedly installed on the opposite side of the fixing member 301. The middle part of the opposite end of the grip rod 302 is fixedly provided with the same pedal 303, and a groove 304 is opened on the surface of the pedal 303. The upper part of the surface of the pedal 303 is arranged as an inclined surface inclined to one side of the wall, and the groove 304 is also opened on the inclined surface.
[0026] By adopting the above technical solution, the escapee can hold the grip bar 302 to climb, which is convenient for manual gripping and force application;
[0027] The pedal 303 is tilted toward one side of the wall, so that the center of gravity of the person tilts toward one side of the wall, thereby effectively preventing the person from falling backward due to an unstable center of gravity when climbing;
[0028] The groove 304 is set with the same slope as the pedal board 303, so as to guide and discharge the accumulated water on the surface of the pedal board 303, thereby avoiding the situation that the surface of the pedal board 303 becomes slippery due to accumulated water;
[0029] The grooves 304 make the surface of the pedal board 303 have different depths, which creates an anti-skid pattern effect, and further improves the stability of the pedal board 303 in supporting pedaling.
[0030] like Figure 2 , Figure 3 and Figure 5 As shown, a slide groove 4 is provided on the front side of the outer surface of the fixing frame 1, a T-block 5 is fixedly installed on the upper rear side of the surface of the extension frame 2, the T-block 5 slides through the slide groove 4 and is located inside the fixing frame 1, and a cable 6 is fixedly installed on the upper end of the T-block 5.
[0031] By adopting the above technical solution, the slide groove 4 performs sliding limiting on the T-block 5 to prevent the extension frame 2 from being separated from the fixed frame 1.
[0032] Furthermore, fixed pulleys 7 are rotatably provided at the left and right corners above the inner surface of the fixed frame 1, and a connecting rod 8 is rotatably provided at the middle of the rear side above the outer surface of the fixed frame 1. Both ends of the connecting rod 8 pass through the fixed frame 1, and a tightening wheel 9 is fixedly installed inside the fixed frame 1, and the upper end of the cable 6 is overlapped from above, bypassed by the fixed pulley 7 and connected to the tightening wheel 9.
[0033] By adopting the above technical solution, the fixed pulley 7 limits the position of the cable 6, thereby preventing the cable 6 from contacting with the inner surface of the fixed frame 1 and causing wear when moving;
[0034] The connecting rod 8 is used to enable the tightening wheels 9 on both sides to rotate synchronously, so as to synchronously reel in the cables 6 , so that the extension frame 2 can move stably.
[0035] like Figure 1 and Figure 6 As shown, a hand wheel 10 is installed on the right side of the surface of the right side tightening wheel 9 inside the fixing frame 1 through a cross bar penetrating the fixing frame 1 , and positioning holes 11 are evenly distributed around the cross bar penetrating the fixing frame 1 .
[0036] By adopting the above technical solution, the cable 6 can be reeled in by manually rotating the hand wheel 10 to drive the retracting wheel 9 .
[0037] Furthermore, a latch 12 is slidably disposed on the surface of the hand wheel 10 , and the left end of the latch 12 is located inside the positioning hole 11 .
[0038] By adopting the above technical solution, the handwheel 10 can be fixed by inserting the pin 12 through the handwheel 10 into the positioning hole 11 at the nearest corresponding position, thereby positioning the tightening wheel 9 to avoid the extension frame 2 falling and unfolding due to its own weight when the escape ladder is not in use.
[0039] Working principle: When using the anti-water accumulation outdoor escape ladder, first, when using the escape ladder, the escapee can hold the handles 302 on both sides with his hands and step on the pedal 303 in the middle to climb. Since the pedal 303 is inclined toward one side of the wall, the center of gravity of the person is inclined toward the wall to prevent the person from falling backwards. At the same time, in rainy days, the inclined groove 304 is used to guide the accumulated water to prevent the accumulation of water, and the surface of the pedal 303 is made of different depths to produce an anti-slip texture effect, so that the escapee can quickly climb and escape. When the floor is high, the extension frame 2 uses its own gravity to expand downward along the slide groove 4 under the limit of the T-block 5. Thereby extending the length of the entire escape ladder. After the escape is completed or when the escape ladder is not in use, the hand wheel 10 is used to drive the right-side tightening wheel 9 to rotate. Under the transmission of the connecting rod 8, the left-side tightening wheel 9 will also rotate to reel in the cable 6, thereby folding the extension frame 2 and the fixing frame 1 to reduce the length of the escape ladder. After the hand wheel 10 has reeled in the cable 6, the latch 12 is inserted through the hand wheel 10 into the positioning hole 11 at the nearest corresponding position, so that the hand wheel 10 can be fixed, thereby positioning the tightening wheel 9 to avoid the situation where the extension frame 2 will fall and unfold due to its own weight when the escape ladder is not in use. This is the working principle of the anti-water accumulation outdoor escape ladder.
