[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a support and adjustment structure for an intelligent tensioning device, comprising: a housing 1 and a protective cover 2. One end of the protective cover 2 is rotatably connected to the surface of the housing 1. A storage groove 3 is provided on the surface of the protective cover 2. One end of a rotating rod 4 is rotatably connected to the storage groove 3. A telescopic rod 6 is movably inserted into the other end of the rotating rod 4. A limit mechanism is provided between the rotating rod 4 and the telescopic rod 6. The storage groove 3 has a rectangular groove structure, and the rotating rod 4 has a rectangular rod structure. The depth of the storage groove 3 is greater than the thickness of the rotating rod 4.

[0023] In actual use, when the display screen on the surface of the cabinet 1 needs to be used, one end of the protective cover 2 is lifted, and then one end of the rotating rod 4 is pulled out from the storage slot 3. The length of the telescopic rod 6 extending out of the rotating rod 4 is adjusted according to the opening angle of the protective cover 2. After adjustment, the limiting mechanism limits the extension length of the telescopic rod 6. Then, the end of the telescopic rod 6 away from the rotating rod 4 is pressed against the surface of the cabinet 1, so that the protective cover 2 can maintain the required opening angle. In this way, the opening angle of the protective cover 2 can be adjusted according to the light intensity, so that the protective cover 2 provides different degrees of light shielding function for the display on the cabinet 1.

[0024] Example 2: Based on Example 1, in order to increase the friction at the end of the telescopic rod 6, a rubber pad 12 is fixed to the end of the telescopic rod 6 away from the rotating rod 4. The rubber pad 12 has a rectangular block structure, and several sets of grooves 13 are formed on the surface of the rubber pad 12.

[0025] A rubber pad 12 is fixed at the end of the telescopic rod 6 away from the rotating rod 4, and a large number of grooves 13 are made on the surface of the rubber pad 12. The rubber pad 12, made of rubber material, is already relatively rough and has a large coefficient of friction. The grooves 13 made on the surface of the rubber pad 12 make the surface of the rubber pad 12 even rougher and the coefficient of friction even greater, thereby increasing the friction at the end of the telescopic rod 6.

[0026] Example 3: Based on Example 2, in order to prevent the rotating rod 4 and the telescopic rod 6 from falling out of the storage groove 3 when they are stored in the storage groove 3, a telescopic rod mounting groove 5 is provided at the end of the rotating rod 4 where the telescopic rod 6 is inserted. The telescopic rod 6 is movably inserted into the telescopic rod mounting groove 5. The telescopic rod 6 has a rectangular rod structure. A spring 7 is fixed at the end of the telescopic rod 6 that extends into the telescopic rod mounting groove 5, and the other end of the spring 7 is fixed to the inner wall of the groove 5.

[0027] A spring 7 is fixed between the telescopic rod 6 and the inner wall of the telescopic rod mounting groove 5. When the rotating rod 4 and the telescopic rod 6 are retracted into the storage groove 3, the spring 7 is in a compressed state. The compressed spring 7 generates a large thrust on the telescopic rod 6. This thrust is transmitted to the contact surface between the rubber pad 12 and the inner wall of the storage groove 3, becoming the pressure between the two. Under the action of a large coefficient of friction and pressure, a large frictional force is generated between the rubber pad 12 and the inner wall of the storage groove 3, thereby causing the rubber pad 12 to limit the rotating rod 4 and the telescopic rod 6 in the storage groove 3.

[0028] Example 4: Based on Example 3, in order to realize the control limiting mechanism, the limiting mechanism includes: screw hole 8, screw 9, friction plate 10 and friction groove 11. Screw hole 8 is opened on the surface of rotating rod 4, and screw 9 is rotatably connected in screw hole 8. Friction groove 11 is opened on the surface of telescopic rod 6, and one end of screw 9 extends into friction groove 11 and fixes friction plate 10.

[0029] A threaded connection is provided between the screw hole 8 and the screw 9, and this threaded connection has a thread self-locking function. When the screw 9 extends into the telescopic rod mounting groove 5 through the threaded connection, causing the friction plate 10 to abut against the inner wall of the friction groove 11, a large frictional force is generated between the friction plate 10 and the inner wall of the friction groove 11, thereby limiting the length of the telescopic rod 6 extending out of the rotating rod 4. When the screw 9 is rotated in the opposite direction, causing the friction plate 10 to leave the inner wall of the friction groove 11, the frictional force disappears, and the limitation is released. At the same time, the friction plate 10 is always slidably connected in the friction groove 11, which can prevent the telescopic rod 6 from exiting the telescopic rod mounting groove 5.

[0030] In actual use, when the display screen on the surface of the cabinet 1 needs to be used, one end of the protective cover 2 is lifted, and then one end of the rotating rod 4 is pulled out from the storage slot 3. The length of the telescopic rod 6 extending beyond the rotating rod 4 is adjusted according to the opening angle of the protective cover 2. After adjustment, the limiting mechanism limits the extension length of the telescopic rod 6. Then, the end of the telescopic rod 6 away from the rotating rod 4 is pressed against the surface of the cabinet 1, which keeps the protective cover 2 at the required opening angle. In this way, the opening angle of the protective cover 2 can be adjusted according to the light intensity, so that the protective cover can be used more efficiently. Cover 2 provides varying degrees of light shielding for the display on the cabinet 1; a rubber pad 12 is fixed to the end of the telescopic rod 6 away from the rotating rod 4, and numerous grooves 13 are formed on the surface of the rubber pad 12. The rubber pad 12, made of rubber material, is already relatively rough with a high coefficient of friction; the grooves 13 further roughen the surface of the rubber pad 12, increasing the coefficient of friction and thus increasing the friction at the end of the telescopic rod 6; a spring 7 is fixed between the telescopic rod 6 and the inner wall of the telescopic rod mounting groove 5. When the rotating rod 4 and the telescopic rod 6... When the rod is stored in the storage slot 3, the spring 7 is compressed. The compressed spring 7 exerts a large thrust on the telescopic rod 6. This thrust is transmitted to the contact surface between the rubber pad 12 and the inner wall of the storage slot 3, becoming the pressure between them. Under the action of a large coefficient of friction and pressure, a large frictional force is generated between the rubber pad 12 and the inner wall of the storage slot 3, thereby limiting the rotating rod 4 and the telescopic rod 6 in the storage slot 3. A threaded connection is provided between the screw hole 8 and the screw 9, and this threaded connection has a thread self-locking function. The threaded connection causes the screw 9 to extend into the telescopic rod mounting groove 5, causing the friction plate 10 to press against the inner wall of the friction groove 11. This generates a large frictional force between the friction plate 10 and the inner wall of the friction groove 11, thus limiting the length of the telescopic rod 6 extending beyond the rotating rod 4. When the screw 9 is rotated in the opposite direction, causing the friction plate 10 to leave the inner wall of the friction groove 11, the frictional force disappears, and the limitation is released. At the same time, the friction plate 10 is always slidably connected in the friction groove 11, which can prevent the telescopic rod 6 from exiting the telescopic rod mounting groove 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
