The term "and / or" used in the specification of the present invention includes any and all combinations of one or more related listed items.

[0035] Combine the following Figure 1-Figure 7 The invention discloses a safety lanyard quick conversion device and a method for using the same.

[0036] like Figure 1 and Figure 4 As shown, in one embodiment, a safety lanyard quick conversion device includes an auxiliary plate 100 , a sliding post 200 , a first engagement assembly 300 and a second engagement assembly 400 .

[0037] The auxiliary plate 100 has a sliding groove 110 , a first special-shaped groove 130 , a second special-shaped groove 140 , a through groove 190 and a first safety hanging rope 120 .

[0038] The sliding column 200 is slidably connected in the sliding groove 110 , and a second safety hanging rope 210 is disposed on the surface of the sliding column 200 .

[0039] It should be additionally explained that the first safety lanyard 120 is fixed to the safety rope via a hook, and the second safety lanyard 210 is fixed to the safety belt worn by the operator.

[0040] When the free end of the first safety lanyard 120 is fixed to the safety pole of the aerial work, the free end of the second safety lanyard 210 is fixed to the aerial work personnel, and vice versa.

[0041] The first engaging assembly 300 is located in the first special-shaped groove 130 and the through-mouth groove 190 . The first engaging assembly 300 matches with the second special-shaped groove 140 on the adjacent auxiliary plate 100 . The first engaging assembly 300 is used to fix the adjacent auxiliary plate 100 .

[0042] It is necessary to add that, see Figure 1 The through groove 190 is the opening portion in the middle of the U-shaped auxiliary plate 100 .

[0043] The second engaging assembly 400 is located in the second special-shaped groove 140 and the through-mouth groove 190 . The second engaging assembly 400 matches with the first special-shaped groove 130 on the adjacent auxiliary plate 100 , and the second engaging assembly 400 is used to fix the adjacent auxiliary plate 100 .

[0044] Among them, the slide groove 110 extends to the free end of the auxiliary plate 100, the first special-shaped groove 130 is located at one end of the auxiliary plate 100, and the second special-shaped groove 140 is located at the other end of the auxiliary plate 100. When two adjacent auxiliary plates 100 are docked and combined to form a whole, the slide column 200 in one auxiliary plate 100 can move into the slide groove 110 of the adjacent auxiliary plate 100.

[0045] When two people need to be in staggered positions during aerial work, the safety lanyard quick conversion device only needs to dock the adjacent auxiliary plates 100 to form a whole. During this process, the first connection component 300 cooperates with the second special-shaped groove 140 on the adjacent auxiliary plate 100, and the second connection component 400 cooperates with the first special-shaped groove 130 on the adjacent auxiliary plate 100 to combine the adjacent auxiliary plates 100 into a whole. When two adjacent auxiliary plates 100 are docked and combined to form a whole, the sliding column 200 in one auxiliary plate 100 can be moved into the sliding groove 110 of the adjacent auxiliary plate 100, thereby realizing the conversion of the second safety lanyard 210 when the two people are in staggered positions. When working at high altitude, the worker only needs to carry a quick conversion hook to realize the quick conversion of the two people in staggered positions. The operation is simple and easy to use. Since the sliding column 200 always slides in the auxiliary plate 100 during the conversion process, the worker and the safety working platform are always connected with the first safety lanyard 120 and the second safety lanyard 210, which can ensure safety and reliability.

[0046] In this embodiment, the longitudinal section of the slide groove 110 is a T-shaped groove or a soil-shaped groove, and the cross section of the slide groove 110 is a U-shaped groove. Therefore, when the worker is working at high altitude, the slide column 200 is always in the auxiliary plate 100, and at the same time, the slide column 200 is slidably connected with the auxiliary plate 100, so that the conversion hook can automatically adjust the angle of the second safety lanyard 210 according to the working environment of the worker.

[0047] In this embodiment, see Figure 4 and Figure 5 The first connecting component 300 and the second connecting component 400 both include a rotating shaft 310 rotatably connected to the auxiliary plate 100, both ends of the rotating shaft 310 extend out of the auxiliary plate 100, the outer wall of the rotating shaft 310 is fixedly connected with a baffle 320, one end of the rotating shaft 310 is fixedly connected with a first limiting plate 340, the other end of the rotating shaft 310 on the first connecting component 300 is fixedly connected with a pressure plate 330, and the other end of the rotating shaft 310 on the second connecting component 400 is fixedly connected with a second limiting plate 430, the pressing plate 330, the first limiting plate 340, and the second limiting plate 430 are all fixedly connected with a torsion spring 350 between the auxiliary plate 100, the first connecting component 300 also includes a card plate 360 ​​fixed on the outer wall of the rotating shaft 310, and the second connecting component 400 also includes a limiting column 420 fixed on the bottom of the auxiliary plate 100.

[0048] In this embodiment, see Figure 2 and Figure 3 The first special-shaped groove 130 and the second special-shaped groove 140 both include a first groove 150, a second groove 160 and a baffle groove 170. The first groove 150 and the second groove 160 are perpendicular to each other. The second groove 160 is located at the end of the auxiliary plate 100. The first groove 150 and the baffle groove 170 are both interconnected with the slide groove 110. The first groove 150 and the second groove 160 are interconnected. The second special-shaped groove 140 also includes a cardboard groove 180. The first groove 150 and the second groove 160 are both interconnected with the cardboard groove 180.

[0049] It should be noted that the rotating shaft 310 is located in the first groove 150, and the clamping plate 360 ​​is located in the second groove 160. When the torsion spring 350 is in the natural state, the clamping plate 360 ​​will not get stuck in the clamping plate groove 180 on the adjacent auxiliary plate 100. The clamping plate 360 ​​will only be stuck in the clamping plate groove 180 on the adjacent auxiliary plate 100 after the pressure plate 330 is lifted up by the limiting column 420. As soon as the pressure plate 330 is lifted up by the limiting column 420, the clamping plate 360 ​​is synchronously and exactly stuck in the clamping plate groove 180 on the adjacent auxiliary plate 100.

[0050] When the slide column 200 enters the interval of the first connecting component 300 or the second connecting component 400, the slide column 200 presses the baffle 320 to prevent the baffle 320 from rebounding, so that the card plate 360 ​​remains stuck in the card plate groove 180 on the adjacent auxiliary plate 100, ensuring that the two auxiliary plates 100 cannot be separated. Only when the two slide columns 200 have completed the conversion and left the interval of the first connecting component 300 or the second connecting component 400, can the card plate 360 ​​be freely separated from the card plate groove 180, thereby ensuring safety.

[0051] In this embodiment, when the torsion spring 350 is in a natural state, the free end of the baffle plate 320 extends into the slide groove 110, thereby preventing the slide column 200 from sliding out of the auxiliary plate 100 during high-altitude operations, thereby ensuring operational safety.

[0052] It should be noted that when the torsion spring 350 is in a natural state, the baffle 320 tilts toward the sliding column 200, and the side of the baffle 320 away from the sliding column 200 abuts against the auxiliary plate 100, so that when the workers are working at high altitudes, the baffle 320 always hinders the movement of the sliding column 200, thereby preventing the sliding column 200 from separating from the auxiliary plate 100, thereby ensuring work safety.

[0053] In this embodiment, when the baffle 320 is located in the baffle groove 170 , the slide groove 110 is connected to the free end of the auxiliary plate 100 , and the slide column 200 can move to the free end of the auxiliary plate 100 , thereby facilitating the conversion of the second safety lanyard 210 .

[0054] In this embodiment, the angle between the baffle 320 and the clamping plate 360 ​​is an obtuse angle, the angle between the baffle 320 and the pressing plate 330 is an obtuse angle, and the angle between the clamping plate 360 ​​and the pressing plate 330 is an acute angle.

[0055] During the rotation of the pressure plate 330, the baffle 320 and the clamping plate 360 ​​can rotate accordingly, and then when the pressure plate 330 is in contact with the limiting column 420 of the adjacent auxiliary plate 100, the clamping plate 360 ​​is clamped in the clamping plate groove 180 of the adjacent auxiliary plate 100, and the baffle 320 is located in the baffle groove 170.

[0056] In this embodiment, the side wall of the baffle 320 is fixedly connected with a support plate 370. When the torsion spring 350 is in a natural state, the support plate 370 abuts against the inner wall of the auxiliary plate 100, thereby facilitating limiting the rotation angle of the baffle 320. When the torsion spring 350 is in a natural state, the baffle 320 can block the movement of the slide column 200 and prevent the slide column 200 from moving out of the auxiliary plate 100, thereby ensuring safety during operation.

[0057] In this embodiment, the free end of the limiting column 420 is fixedly connected to the limiting plate 410. The outer diameter of the limiting plate 410 is larger than the outer diameter of the limiting column 420. The limiting plate 410 is located below the adjacent first limiting plate 340. On the one hand, it is convenient to fix the torsion spring 350 between the limiting plate 410 and the auxiliary plate 100. On the other hand, when the two auxiliary plates 100 are docked, the limiting plate 410 located at the bottom of the auxiliary plate 100 can support the pressure plate 330.

[0058] The present invention also provides a method for using the safety lanyard quick conversion device, comprising the following steps:

[0059] Step S510: When a worker is working at height, Figure 1 , Figure 2 and Figure 3 , the torsion spring 350 is in a natural state, the free end of the baffle 320 in the auxiliary plate 100 extends into the slide groove 110, and the baffle 320 is inclined toward the slide column 200, the support plate 370 abuts against the inner wall of the auxiliary plate 100, and the baffle 320 always hinders the movement of the slide column 200, thereby preventing the slide column 200 from separating from the auxiliary plate 100, ensuring operation safety.

[0060] Step S520, when two people are in staggered positions, refer to Figure 6, so that the free ends of the two auxiliary plates 100 are brought together. When the pressure plate 330 on the left auxiliary plate 100 touches the limiting post 420 on the right second connecting component 400, the pressure plate 330 on the left auxiliary plate 100 will automatically rotate clockwise. At the same time, when the pressure plate 330 on the right auxiliary plate 100 touches the limiting post 420 on the left second connecting component 400, the pressure plate 330 on the right auxiliary plate 100 will automatically rotate counterclockwise, and then the two auxiliary plates 100 are moved until the free ends of the two auxiliary plates 100 are fitted together. In the process of moving the two auxiliary plates 100, the pressure plate 330 is always in contact with the limiting post 420 under the interaction of the limiting post 420 and the torsion spring 350.

[0061] Step S530, when the free ends of the two auxiliary plates 100 are fitted together, the baffle 320 on the left first connecting component 300 is hidden in the baffle groove 170, the slide groove 110 at the lower end of the left auxiliary plate 100 is connected, the card plate 360 ​​on the left first connecting component 300 is clamped in the card plate groove 180 on the right second special-shaped groove 140, and the free end of the baffle 320 on the left second connecting component 400 is still extended into the slide groove 110, blocking the sliding column 200 in the slide groove 110 at the upper end of the left auxiliary plate 100 from moving from left to right.

[0062] Step S540, when the free ends of the two auxiliary plates 100 are fitted together, the baffle 320 on the first connecting component 300 on the right side is hidden in the baffle groove 170, the slide groove 110 on the upper end of the right auxiliary plate 100 is connected, the card plate 360 ​​on the first connecting component 300 on the right side is clamped in the card groove 180 on the second special-shaped groove 140 on the left side, and the free end of the baffle 320 on the second connecting component 400 on the right side is still extended into the slide groove 110, blocking the sliding column 200 in the slide groove 110 at the lower end of the right auxiliary plate 100 from moving from right to left.

[0063] Step S550, move the sliding column 200 in the left auxiliary plate 100 from the lower end of the left auxiliary plate 100 to the right auxiliary plate 100. During this process, when the sliding column 200 moves to the baffle 320 on the right second connecting assembly 400, continue to move the sliding column 200. Under the pushing action of the sliding column 200, the baffle 320 on the right second connecting assembly 400 rotates toward the baffle groove 170 until the sliding column 200 in the left auxiliary plate 100 is completely moved into the right auxiliary plate 100. Under the action of the torsion spring 350 on the right second connecting assembly 400, the baffle 320 on the right second connecting assembly 400 automatically returns to its original position, that is, the free end of the baffle 320 extends into the sliding groove 110 to block the movement of the sliding column 200 in the right auxiliary plate 100.

[0064] In step S560, the slide column 200 in the right auxiliary plate 100 is moved from the upper end of the right auxiliary plate 100 to the left auxiliary plate 100. During this process, when the slide column 200 moves to the baffle 320 on the left second connecting assembly 400, the slide column 200 continues to be moved. Under the pushing action of the slide column 200, the baffle 320 on the left second connecting assembly 400 rotates toward the baffle groove 170 until the slide column 200 in the right auxiliary plate 100 is completely moved into the left auxiliary plate 100. Under the action of the torsion spring 350 on the left second connecting assembly 400, the baffle 320 on the left second connecting assembly 400 automatically returns to its original position, that is, the free end of the baffle 320 extends into the slide groove 110 to block the movement of the slide column 200 in the left auxiliary plate 100.

[0065] Step S570, when the slide column 200 enters the interval of the first connection component 300 or the second connection component 400, the slide column 200 presses the baffle plate 320 to prevent the baffle plate 320 from rebounding, so that the card plate 360 ​​remains in the state of being stuck in the card plate groove 180 on the adjacent auxiliary plate 100, ensuring that the two auxiliary plates 100 cannot be separated. Only when the two slide columns 200 have completed the conversion and left the interval of the first connection component 300 or the second connection component 400, the card plate 360 ​​can be freely separated from the card plate groove 180, thereby realizing the interchange of the second safety hanging rope 210 on the left auxiliary plate 100 and the second safety hanging rope 210 on the right auxiliary plate 100, see Figure 7 After the second safety lanyard 210 is interchanged, the two auxiliary plates 100 are manually pulled to separate the two auxiliary plates 100. As soon as the pressure plate 330 leaves the limiting column 420, under the action of the torsion spring 350, the card plate 360 ​​will synchronously disengage from the card plate slot 180 on the adjacent auxiliary plate 100, thereby realizing the rapid splicing and separation of the two safety lanyard quick conversion devices.

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
