A safety guard folding ladder

Abstract

This invention discloses a safety-protecting folding ladder, comprising a ladder component, a drive component, an outer protective component, and an inner protective component. The ladder component includes a support member, climbing rods, and hanging members. Multiple climbing rods are located at one end of the support member, and the hanging members connected to the outer ends of the support member are L-shaped. The drive component, located at one end of the support member and used in conjunction with the hanging members, includes a drive assembly on one side surface of the support member, a connecting chain at the drive end of the drive assembly, and a locking assembly connected to one end of the connecting chain. This safety-protecting folding ladder, through folding, allows the folded protective ring to cover the steps, preventing accidental climbing and facilitating transport. During climbing, when the stepping components are not activated, the blocking component is unidirectional and cannot open downwards, ensuring direct vertical fall in case of a misstep, while the protective ring provides lateral protection.

Description

Technical Field

[0001] The present invention relates to the field of ladder technology for working at heights, and in particular to a folding ladder with safety protection. Background Technology

[0002] Currently, ladders used for climbing large machinery or metal structures that are frequently moved, as well as other ladders used for working at heights, are generally equipped with fixed guard rings according to safety requirements. Traditional ladders are fixed structures, usually with the ladder and guard ring welded together as a whole. Their volume and shape cannot be changed. They are relatively large and cannot be folded. They take up a lot of space during on-site placement and transportation, and are easily deformed by compression.

[0003] Traditional ladders have a fixed structure and the climbing passage is always unobstructed, which poses a risk of unauthorized personnel climbing them, increasing safety risks. In addition, current ladders with foldable guardrails do not have a labor-saving device during the folding process, which is labor-intensive and inconvenient to operate, and the guardrail cannot be folded at both the top and bottom of the ladder.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0028] Example 1 Reference Figures 1-6 The first embodiment of the present invention provides a safety protection folding ladder, which includes a ladder component 100, a drive component 200, an outer protective component 300 and an inner protective component 400.

[0029] The ladder component 100 includes a support 101, a climbing rod 102, and a hanging member 103. The climbing rod 102 is provided with multiple hanging members 103 at one end of the support 101, and the hanging members 103 connected to the outer end of the support 101 are in an "L" shape.

[0030] During use, the drive component 200 is disposed at one end of the support member 101 and used in conjunction with the hanger 103. It includes a drive assembly 201 disposed on one side surface of the support member 101, a connecting chain 202 disposed at the drive end of the drive assembly 201, and a locking component 203 connected to one end of the connecting chain 202, and the locking component 203 extends to the outer surface of the hanger 103.

[0031] When the drive component 201 is driven, it can enable the locking component 203 to work through the connecting chain 202. The locking component 203 can then lock into the working terrain, providing good safety. The locking mechanism makes the whole system more stable during operation, preventing it from falling off due to the swaying of the ladder.

[0032] Furthermore, the outer protective component 300 is connected to one side of the support member 101. It includes a protective ring 301, a connector 302, and a limiting rod 303. Multiple protective rings 301 are movably disposed on one side of the support member 101, and one end of the protective ring 301 is connected to the drive assembly 201 and extends into the interior of the support member 101. The multiple protective rings 301 and the limiting rod 303 are movably connected.

[0033] Because it is equipped with multiple protective rings 301, the protective rings 301 can effectively protect the staff from falling to the side. The protective rings 301 are designed in an arc shape, which fits the human body better, so that there are more points of force on the human body after falling, thereby improving the safety protection. The limit rod 303 ensures that the folding of the protective rings 301 is more uniform, and the stability under force can also be distributed.

[0034] Furthermore, the inner protective component 400 is provided in the climbing pole 102, and includes a blocking component 401, a rotating blocking component 402, a stepping component 403, and a linkage component 404. The blocking component 401 is connected to the outer end of the climbing pole 102 and cooperates with the rotating blocking component 402 provided in the climbing pole 102. The rotating blocking component 402 cooperates with the stepping component 403 through the linkage component 404, and the stepping component 403 extends to the outer surface of the climbing pole 102. The linkage component 404 is provided in the climbing pole 102.

[0035] The blocking component 401 is prevented from rotating downwards by the anti-rotation component 402. When it is necessary to climb down the ladder, the stepping component 403 can cause the linkage 404 to drive the anti-rotation component 402 to disengage from the blocking component 401. At this time, the blocking component 401 can rotate downwards, effectively preventing accidental falls.

[0036] Example 2 Reference Figure 1This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the drive assembly 201 includes a drive motor disposed on one side of the support member 101 and an output gear 201b disposed at the output end of the drive motor. The connecting chain 202 is wound around and connected to the outer cylindrical surface of the output gear 201b.

[0037] Compared to Embodiment 1, the locking assembly 203 further includes a fixing rod 203a, a locking member 203b, and a resetting member 203c. The fixing rod 203a is connected to one end of the connecting chain 202 and is disposed in the hanger 103 through the resetting member 203c. The locking member 203b connected to its outer end extends out of the outer surface of the hanger 103.

[0038] During use, the engaging member 203b is L-shaped, and the engaging member 203b can be moved by the fixing rod 203a under the action of the resetting member 203c, and the resetting member 203c is elastic.

[0039] The protective ring 301 is connected to one side of the support member 101 via a rotating shaft, and the two rotate together. It is also connected to the limiting rod 303 via the rotating shaft, and the two rotate together. The connecting member 302 meshes with the output gear 201b, and the connecting member 302 can rotate within the support member 101. When the drive motor starts, the drive motor will wind the connecting chain 202 through the output gear 201b and mesh with the connecting member 302. When the connecting chain 202 is under force, the connecting chain 202 pulls the fixing rod 203a and stretches the reset member 203c to charge. At this time, the fixing rod 203a will drive the locking member 203b to move and squeeze and lock the terrain, thereby improving stability. When the connecting chain 202 no longer generates tension, the charged reset member 203c will drive the fixing rod 203a to reset, so that the locking member 203b on the fixing rod 203a is disengaged from the terrain, making it convenient to adjust and move the ladder.

[0040] When the connector 302 is subjected to meshing force, the connector 302 moves and pulls the protective ring 301 to rotate. At this time, the protective ring 301 drives the other protective rings 301 to rotate simultaneously through the limit rod 303 to fold or open, thereby achieving uniformity.

[0041] The remaining structure is the same as that in Example 1.

[0042] Example 3 Reference Figure 1This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the blocking component 401 includes a rotating shaft 401a, a blocking plate 401b, and a groove 401c. The blocking plate 401b is disposed on one side surface of the climbing rod 102 via the rotating shaft 401a and can rotate. The groove 401c opened on the outer surface of the rotating shaft 401a cooperates with the anti-rotation component 402. The anti-rotation component 402 includes a top plate 402a installed in the climbing rod 102 and extending into the groove 401c, and an elastic member 402b disposed inside the climbing rod 102 and connected to the top plate 402a.

[0043] Compared to Embodiment 2, the stepping assembly 403 further includes a stepping rod 403a and an inner groove 403b. The stepping rod 403a extends into the climbing pole 102 and has an inner groove 403b, and the inner groove 403b engages with the barrier plate 401b.

[0044] During use, the top plate 402a and the foot pedal 403a are both engaged with the linkage 404, and the foot pedal 403a can slide in the inner groove 403b. The outer surface of the top plate 402a is inclined and engages with the rotating shaft 401a.

[0045] When the operator climbs upwards via the climbing pole 102, their head first pushes the baffle plate 401b, causing the rotating shaft 401a to rotate. The rotating shaft 401a then... Figure 5 As shown, rotating counterclockwise causes the inner groove 403b in the rotating shaft 401a to press against the inclined surface of the top plate 402a. At this time, the top plate 402a moves, compressing and energizing the elastic element 402b, thereby engaging the top plate 402a with the linkage element 404. The linkage element 404 rotates and engages with the pedal rod 403a, causing the pedal rod 403a to retract. After this process, the inner groove 403b disengages from the barrier plate 401b, so that the rotating shaft 401a can drive the barrier plate 401b to rotate, allowing the operator to continue climbing upwards and rotating.

[0046] During the fall, because the top plate 402a is not disengaged from the inner groove 403b, the rotating shaft 401a cannot rotate clockwise due to the pressure of the flat surface. This allows the user to step on the barrier plate 401b to prevent further fall. When it is necessary to climb down, the process is reversed. By stepping on the foot pedal 403a, the foot pedal 403a can move downward and engage with the linkage 404. The linkage 404 rotates and engages with the top plate 402a. At this time, the top plate 402a slides in the inner groove 403b and compresses and charges the elastic element 402b, disengaging it from the groove 401c. The barrier plate 401b can then rotate downward via the rotating shaft 401a. After disengaging, pushing the barrier plate 401b to rotate the rotating shaft 401a to a certain position will cause the charged elastic element 402b to push the top plate 402a to re-engage with the groove 401c, and this cycle continues.

[0047] The remaining structure is the same as that in Example 2.
