[0011] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0012] Embodiment 1:

[0013] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model discloses a hinge structure between a display screen box and a back cover, wherein the display screen box 1 cooperates with the back cover 2, a concave structure is arranged on one side of the back cover 2, and two hollow raised seats 3 are arranged on the display screen box 1 at a position corresponding to the concave structure, the two raised seats 3 are fitted with the side wall of the concave structure, connecting holes 5 are arranged on the raised seats 3 at the fitting position and the side wall of the concave structure of the back cover 2, a connecting pin 4 is passed through the connecting hole 5, the central axes of the two connecting pins 4 on the same back cover 2 are on the same straight line, a screw hole 7 is arranged inside the raised seat 3 at the end of the connecting pin 4, a bolt 8 is arranged in the screw hole 7, and the bolt 8 is used to limit the movement of the connecting pin 4.

[0014] The raised seat 3 on the display screen housing 1 and the connection hole 5 on the raised seat 3 and the connection hole 5 on the back cover 2 can be realized by the structural design of the side-through mold during the production and processing of the display screen housing 1 and the back cover 2, so it only needs to change the design of the mold, and the processing cost of the back cover 2 and the display screen housing 1 is basically not affected. The connecting pin 4 is a standard part, and its cost is much lower than the use cost of hinges or hinges. Therefore, the connection form of the raised seat 3 and the back cover 2 in this application can reduce the production cost of the display screen. At the same time, the raised seat 3 and the display screen housing 1 are an integrated structure, which is small in size, occupies less space, and the installation process is also simpler and more convenient.

[0015] The side walls of the protruding seat 3 at the connecting hole 5 are offset, and the side wall of the protruding seat 3 corresponding to the half of the connecting hole 5 close to the display screen box 1 is relatively protruding from the side wall of the protruding seat 3 corresponding to the other half of the connecting hole 5. The side walls of the connecting hole 5 on the back cover 2 are also offset, and the side wall of the back cover 2 corresponding to the half of the connecting hole 5 close to the display screen box 1 is relatively protruding from the side wall of the back cover 2 corresponding to the other half of the connecting hole 5. In order to further reduce the space required for the installation of the connecting pin 4, the side walls of the protruding seat 3 and the connecting hole 5 on the back cover 2 are offset. The offset here means that the side wall where each connecting hole 5 is located is divided into two parts, one part is close to the display screen box 1, and the other part is far away from the display screen box 1, and the two parts are divided by a plane in the connecting hole 5 that is parallel to the plane of the display screen box 1; the plane divides the connecting hole 5 into two semicircular holes, and the two semicircular holes of the same connecting hole 5 only partially overlap or do not overlap in their axial positions. Specifically, Figure 3 As shown. For this type of connection hole 5, after the connection hole 5 on the raised seat 3 is connected with the connection hole 5 of the back cover 2, it is only necessary to pull the back cover 2 outwards, and an inclined through hole will be formed between the two connection holes 5, so the connection pin 4 can be inserted obliquely. After the connection pin 4 is in place, the back cover 2 is pressed toward the side of the display box 1 to realize the return of the connection pin 4. This assembly form can reduce the space requirement inside the raised seat 3 and reduce the volume of the raised seat 3. Then, the connection pin 4 is locked by the bolt 8, which limits the movement of the connection pin 4 and prevents the connection pin 4 from tilting, so that the back cover 2 will be more stable and reliable during the rotation process.

[0016] A tail stock 6 of a flat cylindrical structure is provided at the end of the connecting pin 4 located inside the raised seat 3. The diameter of the tail stock 6 is larger than the diameter of the connecting pin 4. A semicircular concave cavity 9 is provided inside the raised seat 3 at a position corresponding to the tail stock 6. The concave cavity 9 is used to embed the tail stock 6. The screw hole 7 is located on the side of the concave cavity 9. The tail of the bolt 8 presses the tail stock 6 of the connecting pin 4.

[0017] A tailstock 6 is provided at the end of the connecting pin 4, and after the connecting pin 4 is inserted into the connecting hole 5 and in place, when the rear cover 2 is pressed toward one side of the display box 1 to cause the connecting pin 4 to return to the normal position, the tailstock 6 at the end of the connecting pin 4 will be clamped in the concave cavity 9, and the concave cavity 9 can axially position the tailstock 6, thereby preventing the connecting pin 4 from axially displacing when the rear cover 2 is opened or closed or in the process, causing the rear cover 2 to fall off, etc., and improving its stability. In addition, since the tailstock 6 of the connecting pin 4 is pressed into the concave cavity 9, it can theoretically pop out of the concave cavity 9 under external pressure, so a bolt 8 is used, and the tail of the bolt 8 presses the tailstock 6 of the connecting pin 4, so that the tailstock 6 of the connecting pin 4 can be restricted in the concave cavity 9, and the concave cavity 9 can be used to limit the axial position of the tailstock 6 of the connecting pin 4, so that the connecting pin 4 can be fully positioned, so the operation of the rear cover 2 is more stable and reliable.

[0018] The above-mentioned hinge structure can effectively reduce the space required for the connection between the display screen housing 1 and the rear cover 2, and the overall volume of the raised seat 3 is also relatively small, and the cost is low.
