[0015] The utility model provides an air curtain display cabinet with automatic doors, which has the following beneficial effects:

[0016] 1. For the air curtain display cabinet with automatic door, when one side of the limit card plate contacts the rubber plate, there is a large friction between the elastically deformable rubber plate and the limit card plate, so the limit card plate is limited. The staff pushes the limit card plate hard, and after the limit card plate leaves the side of the rubber plate, the operating panel loses its limit. The staff pulls the operating panel to move, so that the operating panel drives the fixed sliding sleeve to move, and the sliding sleeve slides on the outside of the support frame. At this time, the top of the sliding sleeve and the top of the support frame can be used to place exhibition items, expanding the bearing area of ​​the top of the support plate composed of the sliding sleeve, support frame, operating panel and other structures, increasing the area for placing exhibits, and increasing the adaptability of the air curtain display cabinet.

[0017] 2. In the air curtain display cabinet of the automatic door, the sliding sleeve is in real-time contact with the pressure sensor. When the sliding sleeve slides a certain distance outside the support frame, the top of the pressure sensor loses the pressure of the sliding sleeve. The pressure sensor detects that the pressure value has changed, and the upper button electrically connected to the pressure sensor is powered off and cannot work, thereby avoiding damage to the door panel and exhibits caused by the staff accidentally pressing the upper button and avoiding economic losses.

[0018] 3. For the wind curtain display cabinet with automatic door, rotate the fixing bolt and insert it into the fixing nut, install the display basket to the bottom of the support frame, and place exhibits on the display basket to expand the display space. The display basket also plays a decorative role, improving the beauty of the wind curtain display cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model embodiment provides an air curtain display cabinet with automatic doors.

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , including an air curtain display cabinet 1, a plurality of support frames 5 are fixedly connected inside the air curtain display cabinet 1, a sliding sleeve 6 is provided on the outer sliding sleeve of the support frame 5, a pressure sensor 14 is provided between the support frame 5 and the sliding sleeve 6, an operating panel 18 is fixedly connected to one side of the bottom of the sliding sleeve 6, a rubber plate 17 and a limiting card plate 20 are provided on one side of the operating panel 18, and a plurality of fixing nuts 7 are fixedly connected to the bottom of the support frame 5.

[0030] When the utility model is in use: two groups of forward and reverse motors 2 are installed on one side of the interior of the air curtain display cabinet 1, one group of forward and reverse motors 2 is composed of two forward and reverse motors 2, and the forward and reverse motors 2 are fixedly installed inside the air curtain display cabinet 1, and the door panel 3 fixedly connected to the output end of the forward and reverse motor 2 is rotatably connected to the air curtain display cabinet 1, so the forward and reverse motors 2 can drive the door panel 3 to rotate when working.

[0031] Two buttons 4 are installed on one side of the air curtain display cabinet 1. Both buttons 4 are electrically connected to four forward and reverse motors 2. The two buttons 4 are divided into an upper button 4 and a lower button 4. After pressing the upper button 4, the four forward and reverse motors 2 electrically connected to the button 4 work forward, so that the four forward and reverse motors 2 drive the four door panels 3 to rotate toward the inside of the air curtain display cabinet 1, so that the door panels 3 are opened inwardly. After pressing the button 4, the forward and reverse motors 2 work reversely to drive the door panels 3 to reset, so that the inside of the air curtain display cabinet 1 is sealed.

[0032] When the lower button 4 is pressed, the four forward and reverse motors 2 electrically connected to the button 4 reverse, and the forward and reverse motors 2 drive the door panels 3 to rotate toward the outside of the air curtain display cabinet 1 to achieve the outward opening of the door panels 3. Then, the button 4 is pressed again to make the forward and reverse motors 2 drive the door panels 3 to reset.

[0033] The rubber plate 17 is fixedly connected to the support frame 5, and the mounting shaft 19 that is rotatably connected inside the limit card plate 20 is fixedly connected to the operating plate 18. When one side of the limit card plate 20 contacts the rubber plate 17, there is a large friction between the rubber plate 17 that can be elastically deformed and the limit card plate 20, so the limit card plate 20 is limited. When the staff pushes the limit card plate 20 with force, the limit card plate 20 overcomes the friction between the limit card plate 20 and the rubber plate 17, and the limit card plate 20 rotates outside the mounting shaft 19. When the limit card plate 20 leaves one side of the rubber plate 17, the operating plate 18 loses its limit. The staff pulls the operating plate 18 to move, so that the operating plate 18 drives the fixed sliding sleeve 6 to move, so that the sliding sleeve 6 slides outside the support frame 5. At this time, the top of the sliding sleeve 6 and the top of the support frame 5 can be placed on the exhibition items, expanding the bearing area of ​​the top of the support plate composed of the sliding sleeve 6, the support frame 5, the operating plate 18 and other structures, increasing the area for placing exhibits, and increasing the adaptability of the air curtain display cabinet 1.

[0034] A mounting groove 13 is provided on the top of the support frame 5, and a pressure sensor 14 is arranged inside the mounting groove 13 and fixedly connected to the support frame 5, so that the sliding sleeve 6 is in real-time contact with the pressure sensor 14. When the sliding sleeve 6 slides a certain distance outside the support frame 5, the top of the pressure sensor 14 loses the pressure of the sliding sleeve 6, and the pressure sensor 14 detects that the pressure value changes. The upper button 4 electrically connected to the pressure sensor 14 is powered off and cannot work, thereby avoiding damage to the door panel 3 and exhibits caused by the staff accidentally pressing the upper button 4, and avoiding economic losses.

[0035] Two first guide grooves 11 are provided on one side of the support frame 5, and a limiting guide rail 15 is provided inside the two first guide grooves 11, and the limiting guide rail 15 is fixedly connected to the sliding sleeve 6. At the same time, two second guide grooves 12 are provided on one side of the support frame 5, and the two second guide grooves 12 are controlled to be connected to the two first guide grooves 11 respectively, and the upper limit short shaft 16 is fixedly installed on one side of the two limiting guide rails 15, and the two limiting short shafts 16 are respectively provided inside the two second guide grooves 12. The limiting guide rail 15, the limiting short shaft 16 cooperate with the first guide groove 11 and the second guide groove 12 to slide the sliding sleeve 6 and the support frame 5 together. And the first guide groove 11 runs through the support frame 5, so the limiting guide rail 15 mainly plays a guiding role for the sliding sleeve 6. The second guide groove 12 does not run through the support frame 5, so the limiting short shaft 16 cannot completely leave the second guide groove 12, so as to prevent the sliding sleeve 6 from leaving the outside of the support frame 5.

[0036] The fixing bolt 8 is rotated and inserted into the fixing nut 7, so that the fixing bolt 8 is fixedly installed at the bottom of the support frame 5, and a fixing vertical rod 9 is fixedly connected to the bottom of the fixing bolt 8, and a display basket 10 is fixedly connected to the bottom of the fixing vertical rod 9, so that the display basket 10 can be installed to the bottom of the support frame 5, and exhibits can be placed on the display basket 10, which can expand the display space, and the display basket 10 plays a decorative role, thereby improving the beauty of the air curtain display cabinet 1.
