Description

Technical Field

[0001] This utility model belongs to the field of ladder technology, specifically relating to a quick-assembly tactical climbing ladder. Background Technology

[0002] Military trucks, often simply called military trucks, are common military vehicles. A key element of combat training is rapid boarding, requiring trainees to climb onto the vehicles as quickly as possible. However, the height of the truck bed chassis and doors makes manual climbing difficult, significantly slowing down the boarding process. Using ladders to improve speed is a good idea, but carrying a ladder around the truck bed all the time is impractical. Therefore, a ladder that can be easily installed and removed is needed. Existing tactical ladders are relatively simple, consisting of a regular ladder with two hooks added to the top to attach to the truck bed doors. The ladder is hung on the truck bed when in use and removed for storage when not in use. However, these ladder hooks lack anti-detachment features. During boarding training, the momentum of personnel quickly leaping onto the ladder can cause it to shake violently or even detach and fall. Furthermore, the existing ladders are long and non-extendable, making them bulky and inconvenient to carry and store. Therefore, there is an urgent need to design a tactical ladder that is easy to carry and quick to assemble and disassemble. Utility Model Content

[0024] Example

[0025] like Figure 1-2As shown, a quick-assembly tactical ladder includes a ladder, a vehicle bed chassis 1, and a vehicle bed door panel 2. The ladder consists of two handrails and multiple horizontally arranged steps 3 connected parallel to the two handrails. Each of the top ends of the two handrails is connected to a hook 4 for hanging above the vehicle bed door panel. The vehicle bed chassis, vehicle bed door panel, ladder, and hooks all adopt existing technology and will not be described in detail here.

[0026] Each of the two handrails is formed by three foldable vertical bars 5 connected together. The three vertical bars forming the same handrail are connected at the middle joints by folding joints 6. Each vertical bar and hook is made of square steel pipe. The top of each of the two handrails is provided with an anti-disengagement device to prevent the hook from moving upward and causing it to disengage. The lower part of the two middle vertical bars is provided with a reverse hook device to be reversed and locked under the chassis of the truck bed to prevent the ladder from swaying.

[0027] The folding joint uses existing technology, which will not be described in detail here. For its specific structure, please refer to the ladder folding joint disclosed in the patent document with application number CN201820908356.9.

[0028] like Figure 3 As shown, the anti-detachment hook device includes an anti-detachment hook 7. A hook window 8 is provided on the top side wall of the handrail facing the corresponding hook. The lower part of the anti-detachment hook is rotatably pinned to the two side walls of the handrail via a pin 9. The upper part of the anti-detachment hook can be tilted out obliquely from the hook window. The lower end of the anti-detachment hook is provided with a limiting part 10, which can abut against the inner wall of the handrail opposite the hook window to limit the upper part of the anti-detachment hook from over-tilting. The upper end of the anti-detachment hook is provided with a check part 11, which can hook back to the bottom of the top frame of the truck bed door to prevent the hook from detaching.

[0029] The top frame of the truck bed door is also made of square steel tubing. The contact edge of the check valve is an L-shaped slot structure that adapts to the outer wall of the square tubing of the top frame. The length of the lower edge 11-1 of the slot of the check valve is less than the length of its upper edge 11-2. A certain movable gap 12 is left between the upper surface of the top frame of the truck bed door and the lower surface of the hook. This movable gap is sufficient to provide the necessary clearance for the lower edge of the slot of the check valve to flip and swing. The swaying gap between the inner side of the top frame of the truck bed door and the inner side of the hook is not enough to allow the upper edge of the slot of the check valve to flip excessively over the outer side of the top frame of the truck bed door, so as to ensure that when the ladder moves upward, the bottom outer corner of the top frame of the truck bed door can be just locked in the slot of the check valve to prevent the hook from falling out.

[0030] The anti-detachment device also includes a torsion spring 13, which is sleeved on the pin. A blocking lever 14 is provided on the anti-detachment hook. The two ends of the torsion spring are respectively hooked between the blocking lever and the lower edge of the hook window, forcing the upper part of the anti-detachment hook to flip and protrude from the hook window.

[0031] The anti-disengagement device also includes an unlocking button. An unlocking hole 15 is correspondingly provided on the side wall of the support rod that abuts against the limiting part. The unlocking button is installed in the unlocking hole. The unlocking button includes a plunger cylinder 16 and a piston rod 17 that is slidably disposed in the plunger cylinder. The plunger cylinder is installed on one side of the unlocking hole. A telescopic ball head 18 is provided at one end of the piston rod facing the limiting part. A button handle 19 is provided at the other end of the piston rod. A return spring 20 is provided between the piston part of the piston rod and the inner end face of the plunger cylinder near the telescopic ball head.

[0032] like Figure 4 As shown, the reverse hook device includes a reverse hook claw 21 and a telescopic sleeve 22. The telescopic sleeve is slidably sleeved on the outside of the vertical rod. The reverse hook claw has an L-shaped structure, with one end fixedly connected to the outer wall of the telescopic sleeve and the other end movable to hook onto the bottom frame of the truck bed chassis. A limit ring 23 is welded to the lower part of the vertical rod inside the telescopic sleeve, and a telescopic spring 24 is provided between the limit ring and the top of the telescopic sleeve.

[0033] A pressing handle 25 is also fixedly installed on the outer wall of the telescopic sleeve, which makes it easy to press the telescopic sleeve downward to unlock the reverse hook claw.

[0034] A rubber post 26 is also fixedly installed on the side wall of the vertical rod above the telescopic sleeve, near the chassis of the truck bed, to cooperate with the reverse hook claw to prevent the ladder from shaking.

[0035] The reverse hook claw is also provided with a guide slope 27 at the end away from the telescopic sleeve, which makes it easier for the reverse hook claw to be pressed directly into the bottom of the truck bed chassis, making the ladder installation faster.

[0036] Both the hook and the reverse hook claw are provided with rubber sleeves 28 to protect the paint at the hook.

[0037] The two folding joints between the three sections of the vertical pole of each handrail are installed in a reverse manner, that is, the two folding joints on the same handrail can fold in opposite directions in a "Z" shape, so that the lower section of the vertical pole can fold outward and the upper section of the vertical pole can fold inward.

[0038] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
