DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: a portable folding display screen protection device, comprising a base 1 and a telescopic frame housing 6, a connecting shaft 11 is fixedly connected to the back of the telescopic frame housing 6, and a rotating rod 12 is movably connected to the outside of the connecting shaft 11, so that the rotating rod 12 can smoothly rotate its position by utilizing the movably connected with the connecting shaft 11, so that the limiting rod 13 can be rotated to a position corresponding to the limiting hole 16, so as to achieve the purpose that the limiting rod 13 can be smoothly inserted into the limiting hole 16;

[0023] One end of the rotating rod 12 is fixedly connected to the limiting rod 13, and one end of the limiting rod 13 is fixedly connected to the toggle block 14. When the limiting rod 13 is inserted into the limiting hole 16, the fixity between the two telescopic frame shells 6 can be ensured to prevent the telescopic protective cotton 10 from shrinking. The toggle block 14 enables the staff to have a force point for toggling the limiting rod 13 outward.

[0024] The limiting rod 13 is connected with a spring 15, and a limiting hole 16 is provided on the back of one of the telescopic frame housings 6. One end of the spring 15 is fixedly connected to the back of the rotating rod 12, and the other end of the spring 15 is fixedly connected to the front of the toggle block 14. The spring 15 makes the limiting rod 13 have elastic force, so that when the limiting rod 13 is located at the limiting hole 16, it can be inserted into the limiting hole 16 to ensure the firmness of the telescopic protective cotton 10;

[0025] A protective shell 2 is fixedly connected to the top of the base 1, and a handle 3 is fixedly connected to the top of the protective shell 2. The protective shell 2 provides a protective point for the entire display screen body 4, and the handle 3 makes the device portable.

[0026] A through hole 17 is provided on the back of the protective shell 2, and an anti-wear layer is provided on the outside of the handle 3. The through hole 17 allows the display screen body 4 to have a space for wiring, thereby preventing the protective shell 2 from blocking the wiring of the display screen body 4 and making it unusable;

[0027] A display screen body 4 is provided above the base 1, and the display screen body 4 is located in the protective shell 2. A storage box 5 is fixedly connected to the top of the base 1, and the storage box 5 provides a storage point for the telescopic frame shell 6 and the telescopic protective cotton 10, so that when the display screen body 4 needs to be used, the telescopic frame shell 6 drives the telescopic protective cotton 10 to be stored in the storage box 5;

[0028] There are four telescopic frame shells 6, one side of which is fixedly connected to one side of the storage box 5, and three telescopic frames 7 are hinged in the four telescopic frame shells 6, so that the telescopic frame shells 6 can smoothly realize the state of expansion or contraction by the hinge between the telescopic frame 7, so that the telescopic protective cotton 10 can be contracted or expanded;

[0029] The bottom of the telescopic frame 7 is fixedly connected with a telescopic rod 8, and the bottom end of the telescopic rod 8 is fixedly connected to the bottom of the inner side of the telescopic frame housing 6, so that the telescopic frame 7 can smoothly perform the corresponding contraction work by utilizing the telescopic characteristics provided by the telescopic rod 8 through the hinge connection with the telescopic frame housing 6;

[0030] The front sides of the two telescopic frame shells 6 are respectively fixedly connected to two connecting blocks 9, and the front sides of the four connecting blocks 9 are fixedly connected to the same telescopic protective cotton 10, so that when the telescopic protective cotton 10 is extended to a certain position, the display screen body 4 can be protected to prevent the display screen body 4 from being damaged by external collisions.

[0031] The working principle of the utility model is:

[0032] When the display screen body 4 needs to be protected, first, one of the telescopic frame shells 6 is pushed to the left, so that when the telescopic frame shell 6 moves to the left, the hinge between the telescopic frame 7 and the telescopic frame 7 can be used to cause the remaining telescopic frame shells 6 and the telescopic frame 7 to be synchronously unfolded, so that one of the telescopic frame shells 6 uses two connecting blocks 9 to drive one side of the telescopic protective cotton 10 to extend to the left, so that when the telescopic protective cotton 10 is extended to a certain position to the left, the display screen body 4 can be protected;

[0033] At this time, the rotating rod 12 can be rotated so that the rotating rod 12 can smoothly achieve a horizontal state by utilizing the movable connection between the rotating rod 12 and the connecting shaft 11, so that the limiting rod 13 can be inserted into the limiting hole 16 by utilizing the elastic force of the spring 15 to ensure the fixing of the telescopic protective cotton 10.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
