Technical Field

[0001] The utility model relates to the technical field of TF cards, and particularly relates to an encrypted TF card. Background Art

[0002] The TF memory card is an extremely small flash memory card, which is mainly used in mobile phones. However, due to its extremely small volume and continuously increasing capacity, it has gradually started to be used in GPS devices, portable music players, and some flash memory disks.

[0003] However, the existing encrypted TF cards are directly exposed to the external environment and lack protection functions. When people carry encrypted TF cards, the encrypted TF cards often come into contact with other objects, resulting in scratches on the surface of the encrypted TF cards, which affects the service life of the encrypted TF cards. Content of the Utility Model

[0004] The purpose of the utility model is to provide an encrypted TF card to solve at least any one of the problems mentioned in the above background art.

Fixed tubes are respectively fixedly installed on the outer walls of both sides of the mounting plate. A U-shaped plate is slidably sleeved on the two fixed tubes. Two semi-circular sponge protection columns are respectively fixedly installed on the inner walls of both sides of the U-shaped plate. Lower circular plates are respectively arranged in the two fixed tubes. Two pressing plates are respectively fixedly installed on the two lower circular plates, and one sides of the four pressing plates respectively extend outside the corresponding fixed tubes. The four pressing plates are respectively slidably connected with the corresponding fixed tubes. Two arc-shaped limiting baffles are respectively fixedly installed in the two fixed tubes. Upper circular plates are respectively arranged in the two fixed tubes. Compression springs are respectively fixedly installed on the outer walls of the two upper circular plates close to each other. Two limiting cross plates are respectively fixedly installed on the two upper circular plates, and the four limiting cross plates are respectively in contact with the corresponding arc-shaped limiting baffles.

[0011] The beneficial effects of the present utility model are as follows:

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides an encrypted TF card as shown in Figure 1-6 which includes an encrypted TF card body 2 fixedly installed on the outer wall of one side of the mounting plate 1. Fixed tubes 4 are respectively fixedly installed on the outer walls of both sides of the mounting plate 1. A U-shaped plate 3 is slidably sleeved on the two fixed tubes 4. Two semi-circular sponge protection columns 15 are respectively fixedly installed on the inner walls of both sides of the U-shaped plate 3. The protection space composed of the U-shaped plate 3, the mounting plate 1 and the semi-circular sponge protection columns 15 protects the encrypted TF card body 2, so that when people carry this device, external objects cannot come into contact with the encrypted TF card body 2, improving the service life of the encrypted TF card body 2. Lower circular plates 5 are respectively arranged in the two fixed tubes 4. Two extrusion plates 6 are respectively fixedly installed on the two lower circular plates 5, and one side of each of the four extrusion plates 6 extends to the outside of the corresponding fixed tube 4. The four extrusion plates 6 are respectively slidably connected to the corresponding fixed tubes 4. Two through openings are respectively formed on the two fixed tubes 4. The four extrusion plates 6 respectively penetrate through the four through openings and are respectively slidably connected to the inner walls of the four through openings. Two arc-shaped limiting baffles 12 are respectively fixedly installed in the two fixed tubes 4. Upper circular plates 9 are respectively arranged in the two fixed tubes 4. In order to make it more convenient for people to operate the upper circular plates 9, adjusting handles 13 are respectively fixedly installed on the outer walls of the two upper circular plates 9 away from each other. Compression springs 8 are respectively fixedly installed on the outer walls of the two upper circular plates 9 close to each other. Two limiting horizontal plates 10 are respectively fixedly installed on the two upper circular plates 9, and the four limiting horizontal plates 10 are respectively in contact with the corresponding arc-shaped limiting baffles 12. In the initial state, the compression springs 8 are in a compressed state. Through the compression springs 8, the lower circular plates 5 are always subjected to a squeezing force, and thus the extrusion plates 6 are always subjected to a squeezing force to squeeze the U-shaped plate 3, thereby increasing the friction force between the extrusion plates 6 and the U-shaped plate 3. Through this friction force, the U-shaped plate 3 can always be stably maintained in the current position without being affected by other external forces.

[0022] In order to limit the horizontal movement of the limiting cross plate 10, and further limit the horizontal movement of the upper circular plate 9, so that the upper circular plate 9 always maintains its current position in the fixed tube 4, and further ensure that the compression spring 8 is always stably installed in the fixed tube 4, two positioning holes 14 are respectively formed in each of the four arc-shaped limiting baffles 12, and positioning rods 16 are respectively slidably installed in the four positioning holes 14, and the four positioning rods 16 are respectively fixedly connected to the corresponding limiting cross plates 10.

[0023] In order to prevent dust from adhering to the compression spring 8 and affecting its service life, dust-proof sponge rings 11 are respectively fixedly installed on the outer walls of the two upper circular plates 9 close to each other. The two dust-proof sponge rings 11 are respectively in contact with the corresponding lower circular plates 5, and the two compression springs 8 are respectively located within the two dust-proof sponge rings 11.

[0024] In order to limit the movement of the extrusion plate 6 so that it can only move up and down and cannot move horizontally, thus making the movement of the extrusion plate 6 in the fixed tube 4 more stable, limiting rods 7 are respectively slidably installed on the four extrusion plates 6, and the four limiting rods 7 are all fixedly connected to the mounting plate 1.

[0025] The working principle of the encrypted TF card provided by the present utility model is as follows: In the initial state, the compression spring 8 is in a compressed state. Due to the compression spring 8, the lower circular plate 5 is always subjected to a squeezing force, and thus the extrusion plate 6 is always subjected to a squeezing force to squeeze the U-shaped plate 3, thereby increasing the friction force between the extrusion plate 6 and the U-shaped plate 3. Due to this friction force, the U-shaped plate 3 can always stably maintain its current position without being affected by other external forces. As a result, the encrypted TF card body 2 is always located within the protection space composed of the U-shaped plate 3, the mounting plate 1, and the semi-circular sponge protection column 15. When people carry this device, external objects cannot come into contact with the encrypted TF card body 2, thus extending the service life of the encrypted TF card body 2. When the device needs to be used, the staff can slightly apply a greater force to rotate the U-shaped plate 3 so that the U-shaped plate 3 rotates around the fixed tube 4, and the encrypted TF card body 2 will be exposed, and the staff can then use the encrypted TF card body 2. When the compression spring 8 needs to be replaced due to metal fatigue caused by long-term compression, first press down the adjustment handle 13 to drive the upper circular plate 9, the limiting cross plate 10, and the positioning rod 16 to move downward. When the positioning rod 16 moves out of the positioning hole 14, rotate the adjustment handle 13 to drive the upper circular plate 9 and the limiting cross plate 10 to rotate, so that the limiting cross plate 10 is misaligned with the arc-shaped limiting baffle 12. Then, move the adjustment handle 13 upward to drive the compression spring 8 suffering from metal fatigue out of the fixed tube 4, and then the compression spring 8 can be replaced. The process is simple and fast, with high work efficiency.

[0026] Compared with the related technologies, the encrypted TF card provided by the present utility model has the following beneficial effects:

[0027] The utility model provides an encrypted TF card. By compressing the spring 8, the friction force between the extrusion plate 6 and the U-shaped plate 3 is increased. Due to this friction force, the U-shaped plate 3 can always be stably maintained at the current position without being affected by other external forces, so that the encrypted TF card body 2 is always located in the protection space composed of the U-shaped plate 3, the mounting plate 1 and the semi-circular sponge protection column 15. In this way, when people carry this device, external objects cannot come into contact with the encrypted TF card body 2, thus improving the service life of the encrypted TF card body 2. By rotating the U-shaped plate 3, the encrypted TF card body 2 can be exposed, and then the staff can use the encrypted TF card body 2. First, hold down the adjustment handle 13 and move it downward to drive the positioning rod 16 out of the positioning hole 14. Then rotate the adjustment handle 13 to drive the upper circular plate 9 and the limit horizontal plate 10 to rotate, so that the limit horizontal plate 10 is misaligned with the arc-shaped limit baffle 12. Next, move the adjustment handle 13 upward to drive the compression spring 8 showing metal fatigue out of the fixed tube 4, and then the compression spring 8 can be replaced. The process is simple and fast, and the work efficiency is high.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
