[0022] 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.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: an air curtain cabinet, comprising: a cabinet body 1; an inner guide rail 2 symmetrically fixed inside the cabinet body 1, three outer limiting slides 3 slidably arranged on one side of the inner guide rail 2, and an inner sliding seat 4 slidably arranged on the inner side of the outer limiting slides 3; a support rack 5 installed on the inner side of the inner sliding seat 4 by bolts; an inner fixed support 6 symmetrically fixed inside the cabinet body 1, one of the inner fixed supports 6 having three second-side fixed boxes 9 slidably arranged on its inner side, one side of the second-side fixed box 9 being fixedly connected to three of the outer limiting slides 3, and another inner fixed support 6 having three first-side fixed boxes 8 slidably arranged on its inner side, one side of the first-side fixed box 8 being fixedly connected to the other three outer limiting slides 3, and a limiting block 10 slidably arranged inside both the first-side fixed box 8 and the second-side fixed box 9; and limiting slots 7 equidistantly opened on the inner side of the inner fixed support 6, the limiting slots 7 cooperating with the limiting blocks 10.

[0024] It should be noted that in this embodiment, the inner guide rail 2 is symmetrically fixed inside the cabinet 1, providing a basic framework for the entire adjustment system. The outer limit slide 3 is located on one side of the inner guide rail 2 and can slide along it, while the inner slide 4 can slide inside the outer limit slide 3. The support rack 5 is bolted to the inner side of the inner slide 4, allowing the support rack 5 to be adjusted in multiple directions inside the cabinet 1. According to the actual placement requirements, the operator can first push the outer limit slide 3 to slide on the inner guide rail 2 to achieve a preliminary position adjustment of the support rack 5 in a certain direction; then push the inner slide 4 to slide inside the outer limit slide 3 to further fine-tune the position of the support rack 5, thereby meeting the placement requirements of different items. A pull rod 11 is slidably installed inside the fixed box 9. One side of three limiting blocks 10 is fixedly connected to the pull rod 11. A spring 13 is sleeved on the outside of the pull rod 11, and a pull block 12 is fixedly connected to one end. When it is necessary to adjust the position of the second side fixed box 9 within the inner fixed support 6, the operator only needs to pull the pull block 12. The pull block 12 drives the pull rod 11 to move, thereby causing the limiting blocks 10 fixed to the pull rod 11 to retract and disengage from the limiting slots 7 on the inner side of the inner fixed support 6. The second side fixed box 9 can then slide freely within the inner fixed support 6. At the same time, since the second side fixed box 9 is fixedly connected to the outer limiting slide 3, it also drives the outer limiting slide 3 to move, thereby adjusting the position of the support rack 5. When the position is adjusted to the appropriate position, the pull block 12 is released, and the spring 13 returns to its original position under its own elastic force. The original state is restored by pushing the pull rod 11 and the limit block 10 back to their original positions, so that the limit block 10 is engaged in the corresponding limit slot 7, thereby fixing the second side fixing box 9 and fixing the position of the outer limit slide 3 and the support frame 5. In addition, the second side fixing box 9 is also threaded with a limit bolt 14 that cooperates with the limit block 10. After the limit block 10 is engaged in the limit slot 7, rotating the limit bolt 14 can further tighten the limit block 10, enhance the stability between the limit block 10 and the limit slot 7, prevent the limit block 10 from accidentally loosening or falling out of the limit slot 7 during use, and improve the reliability of the fixation. The first side fixing box 8 is threaded with an adjusting bolt 15, and one side of the other three limit blocks 10 is rotatably connected to the three adjusting bolts 15. Next, when it is necessary to adjust the position of the first side fixed box 8 within the inner fixed support 6, the operator rotates the adjusting bolt 15. Since the adjusting bolt 15 is threadedly connected to the first side fixed box 8, rotating the adjusting bolt 15 will cause it to move relative to the first side fixed box 8. At the same time, it will drive the limiting block 10, which is rotatably connected to the adjusting bolt 15, to move, causing the limiting block 10 to disengage from the limiting slot 7. At this time, the first side fixed box 8 can slide within the inner fixed support 6, driving the outer limiting slide 3, which is fixed to it, to move, thereby adjusting the position of the supporting material rack 5. After adjusting to the appropriate position, the adjusting bolt 15 is rotated in the opposite direction, causing the limiting block 10 to engage in the corresponding limiting slot 7, thus fixing the first side fixed box 8, and consequently fixing the positions of the outer limiting slide 3 and the supporting material rack 5.An inner sliding block 16 is slidably disposed inside the outer limiting slide block 3. One side of the inner sliding block 16 is fixedly connected to the inner sliding seat 4. The sliding of the inner sliding block 16 within the outer limiting slide block 3 serves as a guide and support, reducing the shaking and deviation of the inner sliding seat 4 during movement and improving the stability of the support frame 5 during installation and movement. A limiting rod 17 is symmetrically slidably disposed inside the inner sliding block 16. The limiting rod 17 is fixedly connected to the outer limiting slide block 3 and provides precise guidance for the sliding of the inner sliding block 16, ensuring that the inner sliding block 16 can only slide in a specific direction. When it is necessary to fix the position of the inner sliding seat 4 relative to the inner sliding block 16, a bottom fixing block 18 is fixedly connected to the bottom of the inner sliding block 16. The bottom fixing block 18 has a positioning hole 21 inside. A bottom fixing support plate 19 is fixedly connected to the bottom of the inner sliding seat 4. The bottom fixing support plate 19 has multiple threaded holes 20 that mate with the positioning hole 21 inside. By passing the limiting bolt 22 through the positioning hole 21 and screwing it into the threaded hole 20, the inner sliding seat 4 and the inner sliding block 16 can be precisely fixed, preventing the inner sliding seat 4 from moving during use and ensuring the stability of the support frame 5.

[0025] As a commercial cold chain equipment, the refrigeration system and structural design of the air curtain cabinet are crucial to its preservation effect and service life. Key components include: the three main components of the refrigeration system: compressor; evaporator, mostly made of pure copper tubing, with some models using 24-tube 16mm diameter copper tubing to increase cooling capacity and maintain uniform temperature; condenser, also made of pure copper tubing for efficient heat dissipation; air curtain circulation system: top air outlets blow cold air downwards, bottom return air inlets recycle air to form an "air curtain" for insulation; waterfall-style airflow at the back evenly covers the cabinet interior, avoiding cooling blind spots; temperature control and energy-saving components: microcomputer digital temperature controller for precise temperature control, with adjustable upper and lower temperature limits and defrosting time; nighttime energy-saving curtains reduce nighttime cold loss; externally balanced thermal expansion valve optimizes cooling efficiency; cabinet structure: integrated foamed steel frame for insulation and sturdiness; corrosion-resistant color steel plate inner liner for extended service life; and fully transparent glass side panels for enhanced display.

[0026] In one embodiment, such as Figures 1 to 5 As shown, a pull rod 11 is slidably installed inside the second side fixing box 9. One side of the three limit blocks 10 is fixedly connected to the pull rod 11. A spring 13 is sleeved on the outside of the pull rod 11. A pull block 12 is fixedly connected to one end of the pull rod 11. An adjusting bolt 15 is threadedly connected inside the first side fixing box 8. One side of the other three limit blocks 10 is rotatably connected to the adjusting bolt 15.

[0027] It should be noted that in this embodiment, the pull rod 11, pull block 12, and spring 13 are combined. The pull rod 11 is installed inside the second side fixing box 9, so that the limiting block 10 is fixedly connected to the pull rod 11, and the spring 13 is sleeved on it, with one end connected to the pull block 12. This design allows the operator to pull the pull block 12 to move the pull rod 11, thereby causing the limiting block 10 to retract. This facilitates the sliding adjustment of the second side fixing box 9 within the inner fixing support 6. When the pull block 12 is released, the elastic force of the spring 13 will cause the limiting block 10 to automatically reset and cooperate with the limiting slot 7 to achieve fixation. The operation is simple and quick, improving the efficiency of adjusting the position of the support rack 5.

[0028] In one embodiment, such as Figures 1 to 5 As shown, an inner sliding block 16 is slidably disposed inside the outer limiting slide 3, and one side of the inner sliding block 16 is fixedly connected to the inner sliding seat 4.

[0029] It should be noted that in this embodiment, an inner sliding block 16 is slidably arranged inside the outer limiting slide block 3, and the inner side of the inner sliding block 16 is fixedly connected to the inner sliding block 4. The sliding of the inner sliding block 16 inside the outer limiting slide block 3 plays a guiding and supporting role, reducing the shaking and deviation of the inner sliding block 4 during the movement process, and improving the stability of the support frame 5 during installation and movement.

[0030] In one embodiment, such as Figures 1 to 5 As shown, the inner sliding block 16 has a symmetrical sliding limit rod 17 inside, and the limit rod 17 is fixedly connected to the outer limit slide 3.

[0031] It should be noted that in this embodiment, a limiting rod 17 is symmetrically slidably arranged inside the inner sliding block 16 and fixedly connected to the outer limiting slide block 3. The limiting rod 17 provides precise guidance for the sliding of the inner sliding block 16, ensuring that the inner sliding block 16 can only slide along a specific direction.

[0032] In one embodiment, such as Figures 1 to 5 As shown, the bottom of the inner sliding block 16 is fixedly connected to a bottom fixing block 18, and the bottom fixing block 18 has two positioning holes 21 inside. The bottom of the inner sliding seat 4 is fixedly connected to a bottom fixing support plate 19, and the bottom fixing support plate 19 has multiple threaded holes 20 that cooperate with the positioning holes 21 inside. The threaded holes 20 are threaded with limiting bolts 22 that cooperate with the positioning holes 21 inside.

[0033] It should be noted that in this embodiment, the bottom of the inner sliding block 16 is fixedly connected to the bottom fixing block 18 and has a positioning hole 21, and the bottom of the inner sliding seat 4 is fixedly connected to the bottom fixing support plate 19 and has a threaded hole 20. A limiting bolt 22 passes through the positioning hole 21 and engages with the threaded hole 20. This design provides precise positioning and firm fixation when it is necessary to fix the position of the inner sliding seat 4 relative to the inner sliding block 16. The engagement of the positioning hole 21 and the threaded hole 20 ensures the accuracy of the fixation, while the limiting bolt 22 ensures the firmness of the fixation, preventing the inner sliding seat 4 from moving during use and ensuring the stability of the support frame 5.

[0034] In one embodiment, such as Figures 1 to 5 As shown, the internal thread of the second side fixing box 9 is fitted with a limiting bolt 14 that mates with the limiting block 10.

[0035] It should be noted that in this embodiment, a limiting bolt 14 that cooperates with the limiting block 10 is installed inside the second side fixing box 9. After the limiting block 10 cooperates with the limiting slot 7 to fix the second side fixing box 9, the limiting bolt 14 can be rotated to further limit the limiting block 10, preventing the limiting block 10 from accidentally loosening or falling out of the limiting slot 7 during use, thereby improving the reliability of fixing the second side fixing box 9.
