Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: A portable air curtain for logistics transportation, such as Figure 1-5 As shown, the air curtain machine body 1 extends in the left-right direction. The front side of the air curtain machine body 1 includes an air inlet. A dust cover 2 is fixedly installed on the front side of the air curtain machine body 1 to prevent dust from entering the air curtain machine body 1 from the air inlet. An air outlet is opened at the bottom of the air curtain machine body 1. The air curtain machine body 1 generates a strong airflow and blows it downward from the air outlet to form an air barrier, which isolates the entrance and exit of the logistics transportation container, preventing hot air, cold air or dust from entering, thereby maintaining the temperature and air quality inside the logistics transportation container and avoiding energy loss. For those skilled in the art, the air curtain machine body 1 is a well-known technology, so it will not be described in detail.

[0022] The air curtain machine body 1 is equipped with a mounting frame 4. Specifically, the mounting frame 4 includes a rectangular frame 41 extending in the left-right direction. The rectangular frame 41 is located on the rear side of the air curtain machine body 1. The rectangular frame 41 includes two square grooves 42 that are spaced apart on the left and right and open from front to back. A plate base 43 is sealed in the square groove 42. The end of the plate base 43 away from the air curtain machine body 1 has multiple right-opening mounting holes. The multiple mounting holes are distributed in a rectangular array. A strong magnetic block 44 is fixed in the mounting holes. Since most logistics transportation boxes are made of steel, the air curtain machine body 1 can be fixedly installed in the logistics transportation box by the multiple array of strong magnetic blocks 44. This allows for adjustment or disassembly of the air curtain machine body 1 according to the needs of the transportation task, making the air curtain machine body 1 easy to carry and disassemble when not needed, saving costs. At the same time, the two sets of strong magnetic blocks 44 that are spaced apart on the left and right and arranged in a rectangular array can be evenly attracted in the logistics transportation box, avoiding unstable installation due to shaking of the box during transportation.

[0023] The rear side of the rectangular frame 41 is fixed with anti-slip protrusions 5. The anti-slip protrusions 5 can increase the friction between the rectangular frame 41 and the inner wall of the logistics transportation box, and prevent the air curtain machine body 1 from sliding due to the shaking of the car body during transportation.

[0024] Multiple connecting frames 7 are provided between the air curtain machine body 1 and the mounting frame 4. The connecting frames 7 can keep the air curtain machine body 1 away from the strong magnetic block 44 located on the mounting frame 4, so as to avoid the magnetic field of the strong magnetic block 44 from affecting the normal use of the air curtain machine body 1. The front end of the connecting frame 7 is fixed on the air curtain machine body 1, and the multiple connecting frames 7 and the square groove 42 are staggered front and back.

[0025] The plate base 43 is slidably disposed within the square groove 42. A drive mechanism 6 is provided on the mounting bracket 4. The plate base 43 is connected to the drive mechanism 6, which drives the plate base 43 to slide left and right. This allows the plate base 43 to be attracted to the inner wall of the logistics transport container by a strong magnetic block 44, or to separate the plate base 43 with the strong magnetic block 44 from the inner wall of the logistics transport container. This facilitates the removal of the air curtain machine body 1 for easy transport and transfer. Specifically, two fixing rods 61, spaced apart from each other, are fixed to the front side of the plate base 43. The fixing rods 61 are located at the front of the square groove 42. In the middle of the opening, a ball bearing 62 is fixedly installed in the middle of the fixing rod 61. The drive mechanism 6 includes a screw 63 fixedly inserted in the ball bearing 62. A threaded hole with front and rear through is opened in the middle of the plate base 43. The rear end of the screw 63 is threaded through the threaded hole. The front end of the screw 63 passes through the ball bearing 62 and is fixedly provided with a handle 64. The handle 64 is located between the air curtain machine body 1 and the rectangular frame 41, and the handle 64 is spaced apart from the air curtain machine body 1 so that the staff can put their hands between the air curtain machine body 1 and the rectangular frame 41 to rotate the handle 64.

[0026] The back side of the plate base 43 has notches 8 at both ends. A limiting block 9 is provided in the notch 8. The limiting block 9 is fixed in the square groove 42. The limiting block 9 can prevent the plate base 43 from going out of the square groove 42. When the notch 8 of the plate base 43 is located in the limiting block 9, the back side of the plate base 43 is flush with the back side of the anti-slip protrusion 5 so that they can be together against the inner wall of the logistics transportation box.

[0027] The connecting frame 7 and the mounting frame 4 are hinged together. The top of the rectangular frame 41 is hinged to the top of the connecting frame 7. Support rods 10 are rotatably provided on the two connecting frames 7 located at the left and right ends of the air curtain machine body 1. The end of the support rod 10 away from the connecting frame 7 is fixed with an insertion rod 11 extending towards the center. Slots 12 are opened at the bottom of the left and right ends of the rectangular frame 41. When the connecting frame 7 and the mounting frame 4 are arranged perpendicularly, the insertion rod 11 at the end of the connecting frame 7 can be inserted into the slot 12 to support the air curtain machine body 1. This allows the mounting frame 4 to be installed on the top of the inner wall of the logistics transportation box, while the air outlet of the air curtain machine body 1 faces downwards, making it usable and improving its applicability.

[0028] The rectangular frame 41, plate base 43, and connecting frame 7 in the mounting bracket 4 are all supported by plastic. The outer shell of the air curtain machine body 1 is also supported by plastic, which can reduce the overall weight of the device, reduce the load on the strong magnetic block 44 when it is adsorbed on the inner wall of the logistics transportation box, and prevent the air curtain machine body 1 from falling off the inner wall of the logistics transportation box.

[0029] Working principle: When installing the air curtain machine body 1, position the plate base 43 to the left of the rectangular frame 41, place the mounting bracket 4 of the air curtain machine body 1 against the inner wall of the logistics transport container, and then turn the handle 64. The handle 64 drives the screw 63 to rotate, causing the plate base 43 to move towards the inner wall of the logistics transport container, so that the strong magnetic block 44 on the plate base 43 is attracted to the inner wall of the logistics transport container, thus completing the fixation. When removing the air curtain machine body 1, turn the handle 64 in the opposite direction. The handle 64 drives the screw 63 to rotate in the opposite direction, causing the plate base 43 to move away from the inner wall of the logistics transport container, so that the strong magnetic block 44 on the plate base 43 is detached from the inner wall of the logistics transport container, thus completing the disassembly.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
