The connection hole 130 is partially provided with threads in the circumferential direction, and partially has a smooth arc surface.

[0060] In this embodiment, the central axis of the internal thread 140 coincides with the axis of the connecting hole 130 .

[0061] In this embodiment, the connecting hole 130 includes two sections of internal threads 140 and two avoidance regions 141 in the circumferential direction. The two sections of internal threads 140 are oppositely arranged, and the two avoidance regions 141 are oppositely arranged.

[0062] In some embodiments, there are three or more sections of internal threads 140 and avoidance regions 141 respectively.

[0063] In this embodiment, a circular hole 142 is formed on the top surface of the connecting hole 130, and the circumferential side wall of the circular hole 142 is a circular structure. The axis of the circular hole 142 coincides with the axis of the connecting hole 130 and also coincides with the axis of the internal thread 140 in the connecting hole 130.

[0064] A marking portion 150 is provided on the bottom surface of the housing, and the position of the marking portion 150 corresponds to the internal thread 140 or the avoidance region 141. In this embodiment, the marking region on the bottom surface of the housing corresponds to the avoidance region 141, so as to be able to indicate the position of the avoidance region 141 and facilitate the alignment during the installation of the base 200.

[0065] In this embodiment, a shielding portion 160 is formed at the bottom of the housing near the connecting hole 130. A notch is formed at the bottom of the circumferential side wall of the connecting hole 130 to form the shielding portion 160.

[0066] In one embodiment, a protruding structure is formed at the bottom of the housing to form the shielding portion 160.

[0067] An elastic rib 170 extending horizontally is provided at the bottom of the housing near the connecting hole 130. One end of the elastic rib 170 is arranged on the housing, and the other end is suspended, so that the elastic rib 170 has elasticity and can undergo elastic deformation.

[0068] The elastic rib 170 is arranged at the bottom of the housing, and there is a gap between the upper surface of the elastic rib 170 and the corresponding region of the housing, so that the elastic rib 170 can undergo elastic deformation in the up and down direction.

[0069] The suspended end of the elastic rib 170 faces the shielding portion 160 and there is a gap between them. There is also a gap between one end of the elastic rib 170 in the horizontal direction and the shielding portion 160, so that the corresponding structure of the base 200 can be restricted between the elastic rib 170 and the shielding portion 160.

[0070] In this embodiment, the elastic rib 170 extends along the circumference of the connecting hole 130. In some embodiments, the elastic rib 170 can extend in a straight line.

Figure 6 It is a structural schematic diagram of the base 200 of the utility model from another perspective. Figure 7 It is a schematic diagram of the connection of the base 200 of the utility model on the shell. Figure 8 yes Figure 7 A cross-sectional view of the structure. Figure 9 It is a schematic diagram of the installation of the base 200 of the utility model. Figure 10 It is a schematic diagram of the base 200 of the utility model after installation.

[0073] See also Figures 1 to 10 The base 200 is detachably fixed to the housing of the display main body 100. The base 200 is provided with a thread so as to be rotatably connected to the housing in a rotating direction.

[0074] The base 200 includes a support frame 210 and a connection column 220 protruding upward from an upper end of the support frame 210 .

[0075] The connecting column 220 is used to connect to the housing, and the supporting frame 210 is used to support the supporting surface. The bottom end of the supporting frame 210 is lower than the bottom end of the display body 100, so as to support the display device on the supporting surface (the ground or the desktop).

[0076] In this embodiment, the support frame 210 is a claw-shaped structure. In some embodiments, the support frame 210 is a plate-shaped structure or a rod-shaped structure.

[0077] The structure of the support frame 210 is not limited. The structure of the support frame 210 refers to the structure of the support frame 210 in the related art, and it only needs that the support frame 210 can be supported on the supporting surface.

[0078] In this embodiment, a protruding external thread 221 is formed on the outer circumference of the connecting column 220; the external threads 221 are spaced apart in the circumferential direction of the connecting column 220. The spaced apart areas between the external threads 221 are avoidance areas 222.

[0079] The number of the external threads 221 corresponds to the number and position of the internal threads 140 in the connecting hole 130 .

[0080] The connecting column 220 is constructed so that it can drive the external thread 221 to move vertically in the avoidance area 141 in the connecting hole 130, and can drive the external thread 221 to rotate, so that the external thread 221 and the internal thread 140 cooperate to drive the connecting column 220 to be limited in the connecting hole 130.

[0081] When the connecting column 220 is inserted upward into the connection, the external thread 221 corresponds to the avoidance area 141, and when the connecting column 220 moves upward, the external thread 221 passes through the avoidance area 141. Then, the base 200 is rotated, and the external thread 221 is driven to rotate by the connecting column 220, so that the external thread 221 and the internal thread 140 are matched, so that the base 200 is fixed on the shell.

[0082] In this embodiment, two external threads 221 are relatively arranged, and two internal threads 140 are relatively arranged. After the connecting column 220 is upwardly inserted into the connecting hole 130, it is rotated 90 degrees so that the connecting column 220 is fixed in the connecting hole 130.

[0083] A limiting portion 223 is provided at the bottom of the connecting column 220 or the upper end of the supporting frame 210, so that when the connecting column 220 is rotated to a preset position so that the external thread 221 and the internal thread 140 cooperate, the limiting portion 223 abuts against the shielding portion 160 to block the rotation of the connecting column 220, thereby effectively ensuring that the base 200 can be installed to the set position, effectively ensuring the stability and reliability of the installation of the base 200 and being able to prompt the user to install the base 200 in place.

[0084] A horizontally extending elastic rib 170 is provided at the bottom of the shell near the connecting hole 130; one end of the elastic rib 170 is provided on the shell, and the other end is suspended; the suspended end of the elastic rib 170 faces the shielding portion 160, and there is a gap between the elastic rib 170 and the shielding portion 160. When the connecting column 220 rotates to a preset position, the two opposite vertical sides of the limiting portion 223 respectively abut against the limiting portion 223 and the elastic rib 170.

[0085] The two opposite sides of the limit portion 223 in the vertical direction respectively abut against the limit portion 223 and the elastic rib 170. The connection column 220 is limited from rotating in the horizontal direction. When the connection column 220 rotates to the preset position, the upper end of the limit portion 223 abuts against the elastic rib 170, so that the elastic rib 170 deforms upward, so that the connection column 220 can rotate to the preset position without interfering with the rotation of the connection column 220. After rotating to the preset position, the elastic member returns to the initial state, so that the two opposite sides of the limit portion 223 in the vertical direction respectively abut against the limit portion 223 and the elastic rib 170. When the base 200 needs to be disassembled, the elastic rib 170 is pressed upward to separate the elastic member and the limit portion 223, so that the base 200 can be rotated to be disassembled.

[0086] In this embodiment, the connection column 220 and the limiting portion 223 both protrude from the upper end surface of the support frame 210. The limiting portion 223 protrudes from the upper end surface of the support frame 210. During the installation or removal of the base 200, the upper end of the limiting portion 223 abuts against the elastic rib 170, and the limiting portion 223 protrudes from the upper end surface of the support frame 210, so as to ensure the strength of the limiting portion 223 and effectively prevent the limiting portion 223 from breaking.

[0087] In some embodiments, the limiting portion 223 protrudes from the peripheral side surface of the connecting column 220 and is disposed at the bottom of the connecting column 220 .

[0088] In some embodiments, the bottom surface of the housing is provided with an identification portion 150, and the position of the identification portion 150 corresponds to the internal thread 140 or the avoidance area 141; the upper end surface of the support frame 210 partially exceeds the connecting column 220 in the horizontal direction, and forms a device identification area 224; the device identification area 224 corresponds to the identification portion 150; the identification area corresponds to the external thread 221 or the interval between the external threads 221. The device identification area 224 on the support frame 210 corresponds to the avoidance area 222 on the connecting column 220.

[0089] The correspondence between the identification area 224 on the base 200 and the identification part 150 on the shell makes it convenient to extend the external thread 221 on the base 200 into the avoidance area 141 when installing the base 200, and facilitates the corresponding insertion of the external thread 221 and the avoidance area 141, thereby improving the installation convenience and efficiency of the base 200.

[0090] A protruding limiting protrusion 226 is formed on the circumference of the connecting column 220 . The limiting protrusion 226 is disposed at the bottom of the connecting column 220 and is located in the interval between the external threads 221 . The limiting protrusion 226 is disposed in the avoiding area 222 .

[0091] The limiting protrusion 226 is constructed so that when the connecting column 220 rotates to a preset position, the limiting protrusion 226 abuts against the side wall of the connecting hole 130 in the avoidance area 141, effectively preventing the connecting column 220 from moving along the radial direction of the connecting column 220, thereby ensuring the stability and reliability of the connection when installed in the connecting hole 130.

[0092] One or more limiting protrusions 226 are provided on the circumference of the connecting column 220. In this embodiment, two limiting protrusions 226 are provided on the circumference of the connecting column 220, and the two limiting protrusions 226 are arranged opposite to each other so as to effectively play a limiting role.

[0093] The end of the limiting protrusion 226 facing away from the connecting column 220 is an arc surface, and the arc surface is matched with the circumference of the connecting hole 130. The arc surface of the connecting column 220 is matched with the circumference of the connecting hole 130 to facilitate the rotation of the connecting column 220 in the connecting hole 130, and to facilitate the disassembly and installation of the base 200. The limiting protrusion 226 extends along the circumference of the connecting column 220, so that the limiting protrusion 226 has a longer length in the circumference of the connecting column 220, so that the position of the connecting column 220 in the connecting hole 130 is more stable.

[0094] A circular hole 142 is formed on the top surface of the connecting hole 130, and a protruding circular cylinder 225 is formed on the upper end of the connecting column 220; the circular cylinder 225 extends into the circular hole 142, and the axis of the circular cylinder 225 coincides with the axis of the external thread 221 on the connecting column 220. The cooperation between the circular cylinder 225 and the circular hole 142 can effectively ensure that the axis of the connecting column 220 and the connecting hole 130 coincides, ensure that the connecting column 220 rotates reliably in the connecting hole 130, and facilitate the rotation of the connecting column 220 in the connecting hole 130.

[0095] In the present invention, a connection hole 130 extending vertically is provided on the bottom surface of the shell, and a protruding internal thread 140 is provided on the inner wall of the connection hole 130; the internal thread 140 is arranged at intervals in the circumferential direction of the connection hole 130, so that an escape area 141 is formed between the intervals of the internal thread 140. The base 200 includes a support frame 210, and a connection column 220 protruding upward from the upper end of the support frame 210; a protruding external thread 221 is formed on the outer circumference of the connection column 220; the external thread 221 is spaced in the circumferential direction of the connection column 220. The connection column 220 is constructed so that the connection column 220 can drive the external thread 221 to move vertically in the escape area 141, thereby driving the connection column 220 to pass through the connection hole 130. The connecting column 220 can also drive the external thread 221 to rotate, so that the external thread 221 and the internal thread 140 cooperate, drive the connecting column 220 to be limited in the connecting hole 130, so that the base 200 is limited on the shell. When installing the base 200, the connecting column 220 passes through the avoidance area 141 and is inserted into the connecting hole 130, and then rotates a preset angle to limit the base 200. The disassembly and assembly of the base 200 does not require the use of tools, which facilitates the installation and disassembly of the base 200.
