Description

Technical Field

[0001] This utility model relates to the field of air cooler equipment technology, and in particular to an industrial air cooler. Background Technology

[0002] Industrial air coolers are environmentally friendly products that are compressor-free, refrigerant-free, and pollution-free. They utilize the principle of evaporative cooling of fresh outdoor air to achieve indoor ventilation and cooling by exchanging air with the indoor air. They are widely used in refrigeration environments such as cold storage and cold chain logistics.

[0003] Traditional industrial air coolers are relatively powerful and heavy. To facilitate movement, casters are usually installed at all four ends of the air cooler body. These casters allow for flexible movement and easy relocation to the desired work area. When the air cooler needs to be fixed in place, the casters can be locked by moving them. However, when moving the air cooler up a slope, its weight requires considerable effort to move and position. Furthermore, when temporarily fixing the air cooler on a slope, personnel must manually lock each caster individually, which is labor-intensive. The act of manually holding the air cooler while locking the casters also poses a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an industrial air cooler.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an industrial air cooler, including a body, universal wheels are provided at four ends of the lower side of the body, a support shell is provided at the lower outer end of the body, a rotating rod is rotatably connected to the support shell, a roller is sleeved at one end of the rotating rod outside the support shell, a ratchet is sleeved at one end of the rotating rod inside the support shell, and a pawl matching the ratchet is provided on the inner wall of the support shell.

[0006] Preferably, the outer wall of the support shell is provided with a sliding plate that is slidably connected to the outer wall of the machine body, and a positioning bolt is screwed onto the sliding plate.

[0021] like Figures 1 to 4 As shown, an industrial air cooler includes a body 1. Universal wheels 2 are installed at four ends of the lower side of the body 1. Hollow support shells 3 are arranged opposite each other on the left and right sides of the lower outer end of the body 1. A rotating rod 5 is horizontally rotatably connected to each of the two sets of support shells 3. The two ends of the rotating rod 5 are located inside and outside the support shell 3, respectively. A roller 4 is fitted onto the outer end of the rotating rod 5. In this embodiment, the roller 4 adopts a design with friction treads to maintain a certain frictional force when in contact with the ground when stationary. A ratchet 6 is fitted onto the inner end of the rotating rod 5 in the support shell 3. The ratchet 6 is concentrically arranged with the roller 4. A pawl 7 matching the ratchet 6 is provided on the inner wall of the support shell 3. A driving plate 11 slides horizontally on the support shell 3, with one end of the driving plate 11 extending into the support shell 3. Inside the support shell 3, and connected to the pawl 7 via a rotating rod 12, a torsion spring 13 is fitted on the outer wall of the rotating rod 12. One end of the torsion spring 13 is connected to the outer wall of the pawl 7, and the other end is connected to the driving plate 11. A guide groove 14 is provided on the support shell 3. The upper end of the driving plate 11 passes through the guide groove 14 and is located outside the support shell 3. A friction pad 15 is provided at the outer end of the driving plate 11 to facilitate personnel contact and increase friction to push the driving plate 11. A telescopic spring 8 is horizontally provided at the inner end of the driving plate 11. In this embodiment, the telescopic spring 8 is not located directly below the guide groove 14. The purpose of this is that the support shell 3 can provide a certain degree of protection for it, preventing stones from the outer wall from directly getting stuck in the gap of the telescopic spring 8.

[0022] The outer wall of the support shell 3 is provided with sliding plates 9 on the left and right sides of the end facing the machine body 1. The sliding plates 9 are set along the height direction of the support shell 3. A cuboid guide block 16 is provided on the outer wall of the machine body 1. A sliding groove 17 is opened on the side of the sliding plate 9 facing the machine body 1, which is slidably connected to the guide block 16. A positioning bolt 10 is screwed to the upper end of the sliding plate 9. The purpose is to facilitate the personnel to position the support shell 3 on the machine body 1.

[0023] When personnel do not need to use the rollers 4 for movement, they first loosen the positioning bolts 10, move the support shell 3 upwards to lift the rollers 4 off the ground, and then tighten the positioning bolts 10 to keep the rollers 4 at a certain height from the ground during the movement.

[0024] Before personnel begin pushing the machine up the slope, the positioning bolt 10 can be loosened to allow the roller 4 to contact the ground, and then tightened to fix the position of the support shell 3. The initial state of the telescopic spring 8 is the extended state, so the ratchet 6 and the pawl 7 are not separated. Personnel then begin pushing the machine 1 up the slope. It should be noted that the direction of the machine 1 going up the slope will be adjusted so that the ratchet 6 is in a counterclockwise state when it is driven. The purpose is to prevent the ratchet 6 and pawl 7 from getting stuck when pushed in the opposite direction. When personnel push the machine 1 onto the slope without exerting force, due to gravity, the machine 1 has a backward sliding force, which drives the pulley to reverse. This causes the ratchet 6 to change its rotation direction through the rotating rod 5, but it is stuck by the pawl 7. As a result, the roller 4 cannot continue to roll, and the machine 1 is restricted from sliding backward. This avoids the problem of the machine 1 sliding down the slope when personnel release it, and also reduces the safety hazards caused by personnel manually locking the machine 1.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
