[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] The utility model is a protective card swiping device for a liquefied natural gas loading station, such as Figure 1 As shown, it includes a card swiping machine 1, and a supporting and fixing mechanism is arranged on the relative side wall of the card swiping machine 1, and the supporting and fixing mechanism is connected to a protective plate 3. The supporting and fixing mechanism can fix the protective plate 3, and can also play a buffering role when the protective plate 3 is hit by foreign objects, thereby effectively preventing the screen of the card swiping machine 1 from being hit by foreign objects. The protective plate 3 is located in front of the screen of the card swiping machine 1. In order to directly view the content displayed on the screen of the card swiping machine 1, the protective plate 3 is made of transparent plastic.

[0025] A dustproof folding cloth 8 is connected to the side of the protective plate 3 opposite to the card reader 1, and the end of the dustproof folding cloth 8 away from the protective plate 3 is connected to the card reader 1; the dustproof folding cloth 8 encloses a dust-free space between the protective plate 3 and the screen of the card reader 1.

[0026] Fixed plates 2 are fixedly connected to the opposite side walls of the card swiping machine 1, and the fixed plates 2 on both sides are movably connected to a shading frame 4 for shading the screen of the card swiping machine 1. In order to ensure the buffering movement of the protective plate 3, the protective plate 3 and the supporting and fixing mechanism are located on the inner side of the shading frame 4.

[0027] By providing a shading frame 4 and a dustproof folding cloth 8, the shading frame 4 can shield the screen of the card reader so that the staff can clearly observe the screen. At the same time, the dustproof folding cloth 8 can block the gap between the protective plate 3 and the screen, making it difficult for external dust to adhere to the outer surface of the screen through the gap, thereby not affecting the user's observation of the content on the screen.

[0028] Example 2

[0029] On the basis of Example 1, Figure 2 As described above, the supporting and fixing mechanism in the protective card swiping device for liquefied natural gas loading station of this embodiment includes a fixed block 9 fixedly connected to the side wall of the card swiping machine 1, the fixed block 9 is fixedly connected to a guide rod 11, the axial direction of the guide rod 11 is perpendicular to the screen of the card swiping machine 1, and a guide block 5 is movably connected to the guide rod 11, the guide block 5 is fixedly connected to the protective plate 3, and when the guide block 5 moves linearly relative to the guide rod 11, it drives the protective plate 3 to move synchronously.

[0030] Furthermore, in order to achieve a better buffering effect and enable the protective plate 3 to return to its original position after being hit by an external object, a spring 10 is sleeved on the guide rod 11, one end of the spring 10 is connected to the fixed block 9, and the other end is connected to the guide block 5. When the protective plate 3 is hit by an external object, the protective plate 3 drives the guide block 5 to move toward the screen of the card reader 1. At this time, the spring 10 is compressed. When the external object can no longer exert force or the force exerted is less than the elastic force of the spring 10, the protective plate 3 moves and returns to its initial state under the action of the spring 10.

[0031] Furthermore, the end of the guide rod 11 away from the fixed block 9 is fixedly connected to the limit plate 6, which blocks the guide block 5, thereby preventing the guide block 5 from being separated from the guide rod 11. When the spring 10 is in an uncompressed state, the guide block 5 abuts against the limit plate 6.

[0032] Example 3

[0033] The present embodiment is used for a protective card swiping device at a liquefied natural gas loading station, comprising a card swiping machine 1, both sides of which are provided with fixed blocks 9, the front of which is provided with a guide rod 11, the guide rod 11 is slidably connected with a guide block 5, the guide rod 11 plays a supporting and limiting role for the guide block 5, thereby ensuring that the guide block 5 does not shake randomly during movement, the side of the guide block 5 is provided with a protective plate 3, the protective plate 3 is transparent plastic, the protective plate 3 is arranged on the front of the screen of the card swiping machine 1, the protective plate 3 can block foreign objects, so that the screen of the card swiping machine 1 is not easily damaged by the impact of foreign objects, and the shape of the protective plate 3 is set as a rectangle. A spring 10 is provided on the side of the guide rod 11, one end of the spring 10 is connected to the fixed block 9, the other end of the spring 10 is connected to the guide block 5, and the other end of the guide rod 11 is provided with a limit plate 6, so as to prevent the guide block 5 from being separated from the guide rod 11.

[0034] Four dustproof folding cloths 8 are provided on the back of the protection plate 3. The four dustproof folding cloths 8 are arranged to enclose a dust-free space between the protection plate 3 and the screen of the card reader 1. The dustproof folding cloths 8 are connected to the card reader 1.

[0035] like Figure 3 As shown, a fixed plate 2 is provided on both sides of the card swiping machine 1, and a limiting groove 7 is provided on the surface of the fixing plate 2 along the top-down direction, and a limiting block 12 is movably connected in the limiting groove 7, and the limiting block 12 is fixedly connected with a shading frame 4. The limiting groove 7 supports and limits the limiting block 12, so that the limiting block 12 can move up and down smoothly in the limiting groove 7, that is, the connection between the shading frame 4 and the fixed plate 2 is realized, and the shading frame 4 can be replaced flexibly and quickly.

[0036] The shading frame 4 can shield the screen of the card reader 1 so that the staff can clearly observe the screen.

[0037] The working principle of the utility model is:

[0038] When the front of the screen of the card reader 1 is hit by a foreign object, the protective plate 3 can block the foreign object, and at the same time, the protective plate 3 moves backward under the action of the foreign object, and the protective plate 3 drives the guide block 5 to move backward on the guide rod 11, so that the guide block 5 compresses the spring 10, and the protective plate 3 drives the dustproof folding cloth 8 to be compressed, and the retractable spring 10 can buffer and absorb the impact force generated by the impact of the foreign object;

[0039] The dustproof folding cloth 8 can block the gap between the protective plate 3 and the screen and reduce the dust adhering to the screen. When the foreign object is separated from the protective plate 3, the spring 10 restores its own shape, so that the spring 10 drives the protective plate 3 and the guide block 5 to reset until the protective plate 3 returns to its initial position.
