Description

Technical Field

[0001] The utility model belongs to the field of dormitory equipment, in particular to a ladder for bunk beds. Background Art

[0002] The upper and lower bunks are usually bunk beds, which are derived in order to make full use of the space and construct the most use value in the smallest range. The upper and lower bunks are usually used with a ladder. The foot pedals of the existing ladders used in the upper and lower bunks are mostly narrow, which will hurt the feet and make it inconvenient to climb the ladder, and it is easy to step on empty space. Therefore, the utility model designs a ladder for the upper and lower bunks. Utility Model Content

[0003] The utility model provides a ladder for bunk beds, which is used to solve the defects in the prior art.

[0004] The utility model is realized through the following technical solutions:

[0005] The lifting of the pedals is achieved by the step of loosening the linkage set up and the step of adjusting the pedals The step of adjusting the pedals is achieved by the step of loosening the linkage set up and the step of adjusting the pedals being achieved.

[0006] In the ladder for bunk beds as described above, rubber pads are fixedly installed at the bottoms of the uprights.

[0007] In the ladder for bunk beds as described above, a plurality of slip rings are respectively mounted on the vertical plates, and the slip rings are respectively fixedly mounted on the inner walls of the corresponding cavities.

[0008] In the ladder for bunk beds as described above, anti-skid pads are fixedly installed on the foot pedals.

[0009] The advantages of the utility model are: the utility model has a simple structure and an ingenious design, and solves the problem of the existing upper and lower bunk ladders that the user is prone to stepping on empty space when climbing, and the foot pedal can be tilted and stored, which can save space and prevent people from accidentally bumping into the foot pedal. It can meet actual needs and is suitable for promotion. When using the utility model, first fix the uprights on the upper and lower bunk bed body, and either welding or bolt fastening can be used for the connection. When in use, step on the foot pedal with your foot, and the foot pedal drives the slide bar to move downward along the slide groove. The torsion spring on the slide bar accumulates potential energy, and at the same time the dial plate rotates in the fan-shaped groove and slides into the slide groove. When the dial plate slides into the slide groove, it drives the slide bar and the foot pedal to rotate. When the slide bar contacts the bottom of the slide groove, the foot pedal rotates to a horizontal position, and the slide bar slides downward to drive the vertical plate to slide downward. The spring rod is compressed, and the vertical plate slides downward and drives The other slide bars slide downward, allowing the other foot pedals to rotate to a horizontal position, making it easier for people to climb the ladder; when the paddle slides into the slide groove, the slide bar cannot rotate due to the restriction of the paddle bar, and thus the foot pedal cannot rotate, making ladder climbing safer and more stable; when the foot pedal is no longer stepped on, the vertical plate automatically resets itself under the action of the spring rod, and at the same time drives the slide bar to automatically reset itself, the slide bar slides out of the slide groove and rotates under the action of the torsion spring, driving the paddle plate to reset itself and the foot pedal to rotate and be tilted for storage, saving space and preventing people from bumping into the foot pedal.

[0014] A ladder for bunk beds, such as Figure 1 , 23, it includes a column 1, the column 1 is provided with two left and right columns and symmetrically distributed, a plurality of pedals 2 are provided between the columns 1, and the characteristics are as follows: the interior of the column 1 is hollow to form a cavity 3, a spring rod 7 is fixedly installed in the cavity 3, the fixed end of the spring rod 7 is fixedly installed at the bottom of the corresponding cavity 3, a vertical plate 6 is fixedly installed on the spring rod 7, and the vertical plate 6 is fixedly installed on the movable end of the spring rod 7, one end of a slide bar 4 is fixedly installed at both ends of the pedal 2, a slide groove 5 is respectively provided on the opposite side of the two columns 1 corresponding to the pedal 2, the slide groove 5 is communicated with the cavity 3, the slide rod 4 is slidably installed in the corresponding slide groove 5, and the slide rod 4 can only Move up and down along the slide 5, the other end of the slide bar 4 is respectively rotatably mounted on the corresponding vertical plate 6, the slide bar 4 is rotatably mounted on the corresponding vertical plate 6 through a bearing, a torsion spring is arranged between the slide bar 4 and the vertical plate 6, and the torsion spring is not marked in the figure. Under the action of the torsion spring, the foot pedal 2 is in an inclined state, and the upper end of the slide 5 is respectively provided with a fan-shaped groove 8, which is connected with the corresponding slide 5, and a dial plate 9 is movably arranged in the fan-shaped groove 8, and the dial plate 9 is fixedly mounted on the corresponding slide bar 4, and the dial plate 9 can rotate in the fan-shaped groove 8 and can slide into the slide 5, and the dial plate 9 is in a horizontal state when it is in the fan-shaped groove 8, and is in a vertical state when it is in the slide 5. The utility model has a simple structure and an ingenious design, solves the problem that the owner of the existing upper and lower bunk ladder is easy to step on the air when climbing, and can store the foot pedal in an inclined manner, which can save space and prevent people from accidentally bumping into the foot pedal, can meet actual needs, and is suitable for promotion. When using the utility model, first fix the upright column 1 on the upper and lower bunk beds, and the connection can be made by welding or bolting. When in use, step on the foot pedal 2 with your foot, and the foot pedal 2 drives the slide bar 4 to move downward along the slide groove 5. The torsion spring on the slide bar 4 accumulates potential energy, and at the same time, the dial plate 9 rotates in the fan-shaped groove 8 and slides into the slide groove 5. When the dial plate 9 slides into the slide groove 5, it drives the slide bar 4 and the foot pedal 2 to rotate. When the slide bar 4 contacts the bottom of the slide groove 5, the foot pedal 2 rotates to a horizontal position, and the slide bar 4 slides downward to drive the vertical plate 6 to slide downward. The spring rod 7 is compressed, and the vertical plate 6 slides downward and The other slide bars 4 are driven to slide downward, so that the other foot pedals 2 are rotated to a horizontal position, which is convenient for people to climb the ladder; when the dial plate 9 slides into the slide groove 5, the slide bar 5 cannot be rotated under the restriction of the dial bar 9, and then the foot pedal 2 cannot be rotated, making it safer and more stable when climbing the ladder; when the foot pedal 2 is no longer stepped on, the vertical plate 6 is automatically reset under the action of the spring rod 7, and the slide bar 4 is automatically reset at the same time, and the slide bar 4 slides out of the slide groove 5 and rotates under the action of the torsion spring, driving the dial plate 9 to reset and the foot pedal 2 to rotate and be tilted for storage, saving space and preventing people from bumping into the foot pedal 2.

[0015] Specifically, as shown in the figure, the bottom of the column 1 in this embodiment is fixedly installed with a rubber pad 20. The rubber pad 20 can prevent the column 1 from rubbing against the ground and generating noise when climbing the ladder while preventing slipping.

[0016] Specifically, as shown in the figure, the vertical plates 6 of this embodiment are respectively provided with a plurality of slip rings 30, and the slip rings 30 are respectively fixedly mounted on the inner walls of the corresponding cavities 3. When the vertical plates 6 move up and down, the slip rings 30 guide the vertical plates 6, making the vertical plates 6 more stable and improving the stability of the ladder.

[0017] Further, as shown in the figure, the foot pedals 2 of this embodiment are respectively fixed with anti-skid pads 40. When climbing the ladder, the anti-skid pads 40 can play an anti-skid role, preventing the foot from slipping and stepping on the foot pedals 2, thereby improving the safety of climbing the ladder.
