[0022] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0023] Figure 2 Shown is a schematic diagram of a straight ladder safety device according to an embodiment of the utility model. Figure 3 Shown is a schematic diagram of the left safety unit in an embodiment of the present utility model. Figure 4 Shown is a schematic diagram of the right safety unit in an embodiment of the present utility model.

[0024] like Figure 2 As shown, an embodiment of the utility model provides a straight ladder safety device, including a straight ladder 1, a tie 2, a left channel steel 3 and a right channel steel 4.

[0025] One end of the strap 2 is fixed to the ladder climber, for example, to the waist, back or abdomen, as long as it can be fixed to the ladder climber. The other end of the strap 2 is provided with an end buckle 21, which is used to connect to the left circular tube 31 or the right circular tube 41, and the end buckle 21 is used to be sleeved on the left circular tube 31 or the right circular tube 41.

[0026] The left channel steel 3 is arranged on the left side of the straight ladder 1. The left channel steel 3 is fixed to the ground or the wall. A left round tube 31 is arranged inside the left channel steel 3. The left round tube 31 is welded and fixed to the left channel steel 3 at both ends, so that the end buckle 21 of the left round tube 31 can also move on the left round tube 31 while being fixed. Figure 2 As shown, a plurality of left safety units 32 are arranged in the extension direction of the left channel steel 3; wherein each left safety unit 32 comprises a wedge block 322 and a stop plate 321, the wedge block 322 and the stop plate 321 are arranged opposite to each other, and the length of the stop plate 321 can be realized to be placed on the wedge block 322 opposite thereto, that is, the sum of the length of the stop plate 321 and the length of the wedge block 322 can be greater than the width of the left channel steel 3. The stop plate 321 is hinged to the left channel steel 3. Figure 5 As shown, a through slot 3211 is provided in the stop plate 321 for the left circular tube 3 to pass through. The size of the end buckle 21 should be larger than the size of the through slot 3211, so that the end buckle 21 cannot pass through the through slot 3211, thereby achieving a stopping effect.

[0027] like Figure 2 and Figure 3 As shown, the cross-sectional shape of the wedge block 322 is a right triangle, wherein one side where the right angle side is located is engaged with the left channel steel, and the other side where the right angle side is located is facing upward. The length of the stop plate 321 can be realized to be placed on the wedge block 322 opposite thereto.

[0028] When the climber climbs up the ladder, one end of the tie 2 is fixed to the climber, and the other end of the tie 2 is provided with an end buckle 21. The end buckle 21 is sleeved on the left circular tube 3. When the climber climbs up normally, driven by the climber, the end buckle 21 pushes the stop plate 321 away and continues to climb up, and then the stop plate 321 falls down and rests on the wedge block 322. If the climber is in danger of falling at this time, the end buckle 21 will be stuck on the stop plate 321, and the stop plate 321 rests on the wedge block 322, so it will not be pushed away, so that the climber will no longer fall, thereby ensuring the safety of the climber.

[0029] Furthermore, in order to ensure that the stop plate 321 falls down in time and rests on the wedge block 322, a clamp spring is provided at the hinge between the stop plate 321 and the left channel steel 3 to provide resistance to the rotation of the stop plate 321. For example, when the stop plate 321 is pushed open to the maximum extent and the end buckle 21 leaves, the stop plate 321 is pulled down and rests on the wedge block 322 under the action of the clamp spring. Alternatively, a spring is provided between the lower side of the stop plate 321 and the wall surface of the left channel steel 3 to provide resistance to the rotation of the stop plate 321. For example, when the stop plate 321 is pushed open to the maximum extent and the end buckle 21 leaves, the stop plate 321 is pulled down and rests on the wedge block 322 under the action of the spring.

[0030] Furthermore, the plurality of left safety units 32 are arranged in the same direction or in a staggered direction. Figure 2 As shown, the plurality of left safety units 32 are arranged in staggered directions, that is, adjacent left safety units 32 have different directions. For example, in one left safety unit 32, the stop plate 321 is arranged on the left side of the left circular tube 31, while the stop plate 321 in the adjacent left safety unit 32 is arranged on the right side of the left circular tube 31; or, in one left safety unit 32, the stop plate 321 is arranged on the right side of the left circular tube 31, while the stop plate 321 in the adjacent left safety unit 32 is arranged on the left side of the left circular tube 31.

[0031] Further, such as Figure 2 and Figure 4As shown, the straight ladder safety device also includes a right channel steel 4. The right channel steel 4 is arranged on the right side of the straight ladder 1, and the right channel steel 4 is fixed to the ground or the wall. A right circular tube 41 is arranged in the right channel steel 4, and the right circular tube 41 is welded and fixed to the right channel steel 4 at both ends. A plurality of right safety units 42 are arranged in the extension direction of the right channel steel 4. Each right safety unit 42 includes a first buffer plate 421 and a second buffer plate 422, and the first buffer plate 421 and the second buffer plate 422 are arranged opposite to each other. The sum of the lengths of the first buffer plate 421 and the second buffer plate 422 is equal to or greater than the width of the right channel steel 4. The first buffer plate 421 and the second buffer plate 422 are both hinged to the right channel steel 4. A through groove 4211 is arranged in the first buffer plate 421 for the right circular tube 4 to pass through. As shown Figure 5 As shown, the size of the end buckle 21 should be larger than the size of the through slot 4211, so that the end buckle 21 cannot pass through the through slot 4211, thereby achieving a stopping effect.

[0032] Figure 6 FIG. 1 is a schematic diagram of an end buckle used in an embodiment of the present utility model. Figure 6 As shown, the end buckle 21 includes a first half clip 211 and a second half clip 212. One end of each of the first half clip 211 and the second half clip 212 is hinged to each other, and the other ends of each of the first half clip 211 and the second half clip 212 are close to each other, for example, Figure 6 As shown, the first half clip 211 and the second half clip 212 are engaged with each other, and a handle 213 is respectively provided on the first half clip 211 and the second half clip 212. A clamp spring is provided at the hinge of the first half clip 211 and the second half clip 212 to achieve the first half clip 211 and the second half clip 212 to be close to each other at the other end.

[0033] A clamp spring is provided at the hinge between the first buffer plate 421 and the second buffer plate 422 and the right channel steel 4 to provide resistance to the rotation of the first buffer plate 421 and the second buffer plate 422, or a spring is provided between the upper side of the first buffer plate 421 and the second buffer plate 422 and the wall surface of the right channel steel 4 to provide resistance to the rotation of the first buffer plate 421 and the second buffer plate 422.

[0034] When the climber is ready to climb down from the straight ladder 1, the climber grabs the handle 213 of the end buckle 21 with his hand, removes the end buckle 21 from the left circular tube 31, and then sleeves the end buckle 21 on the right circular tube 41. As the climber descends, the first buffer plate 421 and the second buffer plate 422 are pushed apart, and the end buckle 21 also moves up and down on the right circular tube 41. If the climber starts to fall due to negligence or slipping, the climber can be prevented from falling because the end buckle 21 is blocked by the first buffer plate 421 and the second buffer plate 422. Even if the force of the first buffer plate 421 and the second buffer plate 422 cannot completely prevent the climber from falling, the speed of falling can still be greatly slowed down, giving the climber enough time to react, such as grabbing the ladder, thereby improving the climber's safety.

[0035] Furthermore, the plurality of right safety units 42 are arranged in the same direction or in a staggered direction. Figure 2 As shown, the plurality of right safety units 42 are arranged in staggered directions, that is, adjacent right safety units 42 have different directions. For example, in one right safety unit 42, the first buffer plate 421 is arranged on the left side of the right circular tube 41, while in an adjacent right safety unit 42, the first buffer plate 421 is arranged on the right side of the right circular tube 41; or, in one right safety unit 42, the first buffer plate 421 is arranged on the right side of the right circular tube 41, while in an adjacent right safety unit 42, the first buffer plate 421 is arranged on the left side of the right circular tube 41.

[0036] The straight ladder safety device provided by the utility model provides anti-fall fixation and falling buffer for ladder climbers by setting a left safety unit 32 and a right safety unit 42, thereby improving the safety of ladder climbers without the assistance of others.
