DETAILED DESCRIPTION

[0042] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0043] See also Figure 1-Figure 5 As shown, the dual-screen splicing bracket 1000 of this embodiment includes a fixing frame 1, a main screen mounting seat 2 for carrying a main screen 4, a sub-screen mounting seat 3, a flat-flipping mechanism 100 and a side-flipping mechanism 200. The side of the sub-screen mounting seat 3 is bent and extended to form a bending portion 31, and the bending portion 31 is located on the side of the fixing frame 1. Preferably, the side of the sub-screen mounting seat 3 is bent by 90° to form the above-mentioned bending portion 31.

[0044] The horizontal flip mechanism 100 is horizontally connected to the fixing frame 1, and the main screen mounting seat 2 and the auxiliary screen mounting seat 3 are respectively connected to the horizontal flip mechanism 100 and can be rotated up and down, and the auxiliary screen mounting seat 3 can be rotated to the plane where the main screen mounting seat 2 is located. Driven by the horizontal flip mechanism 100, the main screen mounting seat 2 and the auxiliary screen mounting seat 3 are flipped up and down, thereby realizing the splicing operation of the main screen 4 and the auxiliary screen 5 in the up and down direction to meet different usage requirements. Driven by the horizontal flip mechanism 100, the main screen 4 and the auxiliary screen 5 can be unfolded at a certain angle to realize screen splicing. Figure 2 The schematic diagram shows the state after the secondary screen 5 is rotated 90°. Figure 3 The schematic diagram shows the state after the secondary screen 5 is rotated 180°.

[0045] The side-turning mechanism 200 is connected to the bending part 31 which can rotate left and right in the vertical direction, and the auxiliary screen 5 can be connected to the side-turning mechanism 200 which can rotate left and right, and the auxiliary screen 5 can be rotated to the plane where the main screen mounting seat 2 is located. Driven by the side-turning mechanism 200, the auxiliary screen 5 can be flipped left and right, so as to realize the splicing operation of the main screen 4 and the auxiliary screen 5 along the left and right directions to meet different usage requirements. Driven by the side-turning mechanism 200, the auxiliary screen 5 can be unfolded at a certain angle to realize the splicing of the screens. Figure 4 The schematic diagram shows the state after the secondary screen 5 is rotated 90°. Figure 5 FIG. 5 shows a schematic diagram of the state after the secondary screen 5 is rotated 180°. For the convenience of description, in the initial state, the secondary screen 5 is not unfolded. Figure 1 As shown, it is located on the auxiliary screen mounting base 3 and is parallel to the main screen 4. At this time, the main screen 4 and the auxiliary screen 5 are located on the front and back of the fixing frame 1 respectively.

[0046] The structures of the flat-turning mechanism 100 and the side-turning mechanism 200 of this embodiment will be described in detail below.

[0047] See also Figure 1-Figure 3 , Figure 6 and Figure 7 As shown, the flat-flipping mechanism 100 of this embodiment includes a first rotating shaft 110 connected to the auxiliary screen mounting base 3, a second rotating shaft 120 connected to the main screen mounting base 2, and a first locking assembly 130. The first rotating shaft 110 and the second rotating shaft 120 are arranged in parallel and pass through the first locking assembly 130 respectively. The first rotating shaft 110 can rotate around the axis of the first rotating shaft 110 relative to the first locking assembly 130, and the second rotating shaft 120 can rotate around the axis of the second rotating shaft 120 relative to the first locking assembly 130. The first locking assembly 130 limits the rotation of the second rotating shaft 120 until the first rotating shaft 110 rotates to a first preset angle. The first locking assembly 130 limits the rotation of the first rotating shaft 110 until the second rotating shaft 120 rotates to a second preset angle, thereby limiting the rotation of only one rotating shaft in the flat-flipping mechanism 100 through the first locking assembly 130 to be in a rotating state.

[0048] The first locking assembly 130 includes a first gasket 131, a first locking gasket 132, and a second gasket 133 stacked in sequence. The first locking gasket 132 is slidably connected to the first gasket 131 and the second gasket 133, and is limited to slide between the first rotating shaft 110 and the second rotating shaft 120 to limit the rotation of either the first rotating shaft 110 or the second rotating shaft 120. Specifically, the first locking gasket 132 protrudes toward the first gasket 131 and the second gasket 133 to form a first protrusion 1321, and the first gasket 131 and the second gasket 133 are respectively provided with a first groove for the first protrusion 1321 to slide. The first locking gasket 132 is clamped between the first gasket 131 and the second gasket 133, and the two first protrusions 1321 extend into the corresponding first grooves, so as to realize the limited sliding of the first locking gasket 132 between the first gasket 131 and the second gasket 133.

[0049] See also Figure 1-Figure 3 , Figure 6-Figure 9 As shown, the first locking assembly 130 also includes a first locking gasket 134 and a second locking gasket 135 located between the first gasket 131 and the second gasket 133. The first locking gasket 134 is arranged on the first rotating shaft 110 and rotates synchronously with the first rotating shaft 110. The second locking gasket 135 is arranged on the second rotating shaft 120 and rotates synchronously with the first rotating shaft 110. When the first rotating shaft 110 rotates, the first gasket 131 squeezes and pushes the first locking gasket 132 toward the second rotating shaft 120 to limit the rotation of the second rotating shaft 120; when the second rotating shaft 120 rotates, the second gasket 133 squeezes and pushes the first locking gasket 132 toward the first rotating shaft 110 to limit the rotation of the first rotating shaft 110.

[0050] Specifically, the first engaging gasket 134 forms a first notch 1341, and the second engaging gasket 135 forms a second notch 1351. In the initial state, the first notch 1341 and the second notch 1351 are as follows: Figure 8 The first locking gasket 132 is shown as facing the first locking gasket 132. At this time, the first locking gasket 132 can slide between the first notch 1341 and the second notch 1351, that is, in the initial state, the first rotating shaft 110 or the second rotating shaft 120 can be rotated first. Fig. 9 As shown, the notch portion is switched toward the first locking pad 132 to the non-notch portion is switched toward the first locking pad 132, and the non-notch portion of the first engaging pad 134 abuts and pushes the first locking pad 132 into the second notch 1351 to lock the rotation of the second rotating shaft 120. When the first rotating shaft 110 rotates to the first preset angle, the first notch 1341 faces the first locking pad 132. At this time, both the first notch 1341 and the second notch 1351 face the first locking pad 132, that is, the first rotating shaft 110 or the second rotating shaft 120 can be selected to rotate.

[0051] Correspondingly, the second rotating shaft 120 is rotated, and the second engaging gasket 135 is switched from the notch portion toward the first locking gasket 132 to the non-notch portion toward the first locking gasket 132, and the non-notch portion of the second engaging gasket 135 abuts and pushes the first locking gasket 132 into the first notch 1341 to lock the rotation of the first rotating shaft 110. When the second rotating shaft 120 is rotated to the second preset angle, the second notch 1351 faces the first locking gasket 132, and at this time, the first notch 1341 and the second notch 1351 both face the first locking gasket 132, that is, the first rotating shaft 110 or the second rotating shaft 120 can be rotated again. Through the above steps, the position of the first locking gasket 132 relative to the first notch 1341 and the second notch 1351 is switched, thereby achieving the locking of the first rotating shaft 110 or the second rotating shaft 120.

[0052] See also Figure 1-Figure 3 , Figure 6 and Figure 7 As shown, in order to limit the first rotating shaft 110 to rotate only to the first preset angle and limit the second rotating shaft 120 to rotate only to the second preset angle, the first locking assembly 130 also includes a first stop plate 136 and a second stop plate 137. The first stop plate 136 and the second stop plate 137 are respectively located on the side of the first gasket 131 away from the first locking gasket 132. The first stop plate 136 is arranged on the first rotating shaft 110 and rotates synchronously with the first rotating shaft 110. The first stop plate 136 limits the first rotating shaft 110 to rotate within the first preset angle. By adjusting the relative distance between the first stop plate 136 and the first gasket 131, the first preset angle can be set to any value. Correspondingly, the second stop plate 137 is provided on the second rotating shaft 120 and rotates synchronously with the second rotating shaft 120. The second stop plate 137 limits the rotation of the second rotating shaft 120 within a second preset angle. By adjusting the relative distance between the second stop plate 137 and the second gasket 133, the second preset angle can be set to any value.

[0053] The flat flip mechanism 100 of this embodiment further includes a first connection gasket 140, two first fixing nuts 180 and a first nut column 150 for fixing with an external device. The first rotating shaft 110 and the second rotating shaft 120 pass through the first connection gasket 140 respectively, so that the connection between the first rotating shaft 110 and the second rotating shaft 120 is more stable. The first fixing nut 180 fixes the first connection gasket 140 with the first locking assembly 130. Specifically, the first fixing nut 180 presses the second gasket 133, the first locking gasket 132, the snap-fit ​​gasket, and the first gasket 131 onto the stopper to achieve the assembly of the second gasket 133, the first locking gasket 132, the snap-fit ​​gasket, and the first gasket 131. The first nut column 150 is installed on the first connection gasket 140, so that the flat flip mechanism 100 can be fixed with an external device through the first nut column 150.

[0054] It should be noted that the first preset angle and the second preset angle of this embodiment are generally set to 90°, so that the secondary screen 5 can be Figure 2 After rotating 90° around the first rotating shaft 110, the main screen 4 is at an angle of 90°, and then rotating 90° around the second rotating shaft 120, the main screen 4 is at an angle of 90°. Figure 3 As shown, it is located at the same horizontal plane as the main screen 4 to realize the screen splicing operation. Of course, the first preset angle and the second preset angle can also be set to other angles to meet the usage requirements of different occasions, which will not be repeated here.

[0055] See also Figure 1-Figure 3 , Figure 6 and Figure 7 As shown, the flipping mechanism 100 also includes a first concave cam assembly 160 and a second concave cam assembly 170. The first rotating shaft 110 and the second rotating shaft 120 pass through the first connecting gasket 140 respectively. The first concave cam assembly 160 provides a torque opposite to the rotation direction of the first rotating shaft 110 to the first rotating shaft 110, and the second concave cam assembly 170 provides a torque opposite to the rotation direction of the second rotating shaft 120 to the second rotating shaft 120, thereby overcoming the influence of the screen weight on the rotation process, reducing the rotation difficulty and instability caused by the screen weight, and effectively improving the rotation feel.

[0056] Specifically, the first concave cam assembly 160 includes a first concave wheel 161, a first cam 162, a first compression spring 163 and a first adjusting nut 164. The first concave wheel 161, the first cam 162, the first compression spring 163 and the first adjusting nut 164 are sequentially arranged on the first rotating shaft 110. The first concave wheel 161 and the first cam 162 are concave-convex matched, and the first concave wheel 161 is fixed on the first connecting gasket 140. The first cam 162 rotates synchronously with the first rotating shaft 110 and can slide along the first rotating shaft 110. The first compression spring 163 constantly pushes the first cam 162 toward the first concave wheel 161. When the auxiliary screen 5 flips up, the first concave wheel 161 and the first cam 162 rotate relative to each other and gradually climb the slope, and the first compression spring 163 is gradually compressed. Since the first cam 162 can slide along the first rotating shaft 110, the first cam 162 has a tendency to go downhill relative to the first concave wheel 161 under the push of the first compression spring 163, thereby generating a torque opposite to the rotation direction of the first rotating shaft 110 to offset part of the screen weight and improve the flipping feel; when the auxiliary screen 5 flips down, the first concave wheel 161 and the first cam 162 rotate relative to each other and gradually go downhill, and the first compression spring 163 is gradually reduced in compression. Since the first cam 162 can slide along the first rotating shaft 110, the first cam 162 has a tendency to climb the slope relative to the first concave wheel 161 under the push of the first compression spring 163, thereby generating a torque opposite to the rotation direction of the first rotating shaft 110 to offset part of the screen weight and avoid the screen falling phenomenon, thereby improving the flipping feel.

[0057] Correspondingly, the second concave cam assembly 170 includes a second concave wheel 171, a second cam 172, a second compression spring 173 and a second adjusting nut 174. The second concave wheel 171, the second cam 172, the second compression spring 173 and the second adjusting nut 174 are sequentially arranged on the second rotating shaft 120. The second concave wheel 171 and the second cam 172 are concave-convex matched, and the second concave wheel 171 is fixed on the first connecting gasket 140. The second cam 172 rotates synchronously with the second rotating shaft 120 and can slide along the second rotating shaft 120. The second compression spring 173 constantly pushes the second cam 172 toward the second concave wheel 171. When the main screen 4 is flipped up, the second concave wheel 171 and the second cam 172 rotate relative to each other and gradually climb the slope, and the second compression spring 173 is gradually compressed. Since the second cam 172 can slide along the second rotating shaft 120, the second cam 172 has a tendency to move downhill relative to the second concave wheel 171 under the push of the second compression spring 173, thereby generating a torque opposite to the rotation direction of the second rotating shaft 120 to offset part of the screen weight and improve the flipping feel; when the main screen 4 is flipped down, the second concave wheel 171 and the second cam 172 rotate relative to each other and gradually climb the slope, and the second compression spring 173 is gradually reduced in compression. Since the second cam 172 can slide along the second rotating shaft 120, the second cam 172 has a tendency to climb the slope relative to the second concave wheel 171 under the push of the second compression spring 173, thereby generating a torque opposite to the rotation direction of the second rotating shaft 120 to offset part of the screen weight and avoid the screen falling phenomenon, thereby improving the flipping feel.

[0058] See also Figure 1-Figure 3 , Figure 6-Figure 9 As shown, in summary, the beneficial effects of the flipping mechanism 100 are: on the one hand, since the rotation of the two rotating shafts is restricted by the first locking assembly 130 in turn, when one of the two rotating shafts is in a rotating state, the other is in a stationary state, thereby realizing the switching of the rotatable rotating shaft; on the other hand, the rotation restriction of the other rotating shaft by the first locking assembly 130 can be released only when the rotating shaft is rotated to a preset angle, so that different unfolding states of the flipping mechanism 100 can be realized by setting different preset angles.

[0059] See also Figure 1 , Figure 4 and Figure 5 , Fig.10 and Fig.11As shown, the rollover mechanism 200 of this embodiment includes a third rotating shaft 210, a fourth rotating shaft 220 and a second locking assembly 230, the auxiliary screen mounting seat 3 is connected to the fourth rotating shaft 220, and the auxiliary screen 5 is connected to the third rotating shaft 210. The third rotating shaft 210 and the fourth rotating shaft 220 are arranged in parallel and pass through the second locking assembly 230 respectively. The third rotating shaft 210 can rotate around the axis of the third rotating shaft 210 relative to the second locking assembly 230, and the fourth rotating shaft 220 can rotate around the axis of the fourth rotating shaft 220 relative to the second locking assembly 230. The second locking assembly 230 limits the rotation of the fourth rotating shaft 220 until the third rotating shaft 210 rotates to the third preset angle, and the second locking assembly 230 limits the rotation of the third rotating shaft 210 until the fourth rotating shaft 220 rotates to the fourth preset angle, so that only one rotating shaft in the rollover mechanism can be in a rotating state through the second locking assembly 230.

[0060] The second locking assembly 230 includes a third gasket 231, a second locking gasket 232 and a fourth gasket 233 stacked in sequence. The second locking gasket 232 is slidably connected to the third gasket 231 and the fourth gasket 233, and is limited to slide between the third rotating shaft 210 and the fourth rotating shaft 220 to limit the rotation of either the third rotating shaft 210 or the fourth rotating shaft 220. Specifically, the second locking gasket 232 protrudes toward the third gasket 231 and the fourth gasket 233 to form a second protrusion 2321, and the third gasket 231 and the fourth gasket 233 are respectively provided with a second groove for the second protrusion 2321 to slide. The second locking gasket 232 is clamped between the third gasket 231 and the fourth gasket 233, and the two second protrusions 2321 extend into the corresponding second grooves, so as to realize the limited sliding of the second locking gasket 232 between the third gasket 231 and the fourth gasket 233.

[0061] See also Figure 1 , Figure 4 and Figure 5 , Figure 10-13 As shown, the second locking assembly 230 also includes a third locking gasket 234 and a fourth locking gasket 235 located between the third gasket 231 and the fourth gasket 233. The third locking gasket 234 is arranged on the third rotating shaft 210 and rotates synchronously with the third rotating shaft 210. The fourth locking gasket 235 is arranged on the fourth rotating shaft 220 and rotates synchronously with the fourth rotating shaft 220. When the third rotating shaft 210 rotates, the third locking gasket 234 squeezes and pushes the second locking gasket 232 toward the fourth rotating shaft 220 to limit the rotation of the fourth rotating shaft 220; when the fourth rotating shaft 220 rotates, the fourth locking gasket 235 squeezes and pushes the second locking gasket 232 toward the third rotating shaft 210 to limit the rotation of the third rotating shaft 210.

[0062] Specifically, the third engaging gasket 234 forms a third notch 2341, and the fourth engaging gasket 235 forms a fourth notch 2351. In the initial state, the third notch 2341 and the fourth notch 2351 are as follows: Fig.12 The third locking gasket 234 is shown as facing the second locking gasket 232. At this time, the second locking gasket 232 can slide between the third notch 2341 and the fourth notch 2351, that is, in the initial state, the third rotating shaft 210 or the fourth rotating shaft 220 can be rotated first. Fig.13 As shown, the notch portion is switched toward the second locking pad 232 to the non-notch portion is switched toward the second locking pad 232, and the non-notch portion of the third engaging pad 234 abuts against and pushes the second locking pad 232 into the fourth notch 2351 to lock the rotation of the fourth rotating shaft 220. When the third rotating shaft 210 rotates to the third preset angle, the third notch 2341 faces the second locking pad 232. At this time, both the third notch 2341 and the fourth notch 2351 face the second locking pad 232, that is, the third rotating shaft 210 or the fourth rotating shaft 220 can be rotated again.

[0063] Correspondingly, the fourth rotating shaft 220 is rotated, and the fourth engaging gasket 235 is switched from the notch portion toward the second locking gasket 232 to the non-notch portion toward the second locking gasket 232, and the non-notch portion of the fourth engaging gasket 235 abuts and pushes the second locking gasket 232 into the third notch 2341 to lock the rotation of the third rotating shaft 210. When the fourth rotating shaft 220 is rotated to the fourth preset angle, the fourth notch 2351 faces the second locking gasket 232, and at this time, the third notch 2341 and the fourth notch 2351 both face the second locking gasket 232, that is, the third rotating shaft 210 or the fourth rotating shaft 220 can be rotated again. Through the above steps, the position of the second locking gasket 232 relative to the third notch 2341 and the fourth notch 2351 is switched, thereby achieving the locking of the third rotating shaft 210 or the fourth rotating shaft 220.

[0064] See also Figure 1 , Figure 4 and Figure 5 , Fig.10 and Fig.11As shown, in order to limit the third rotating shaft 210 to rotate only to the third preset angle and limit the fourth rotating shaft 220 to rotate only to the fourth preset angle, the second locking assembly 230 also includes a third stop plate 236 and a fourth stop plate 237. The third stop plate 236 and the fourth stop plate 237 are respectively located on the side of the third gasket 231 away from the second locking gasket 232. The third stop plate 236 is arranged on the third rotating shaft 210 and rotates synchronously with the third rotating shaft 210. The third stop plate 236 limits the third rotating shaft 210 to rotate within the third preset angle. By adjusting the relative distance between the third stop plate 236 and the third gasket 231, the third preset angle can be set to any value. Correspondingly, the fourth stop plate 237 is provided on the fourth rotating shaft 220 and rotates synchronously with the fourth rotating shaft 220. The fourth stop plate 237 limits the rotation of the fourth rotating shaft 220 within a fourth preset angle. By adjusting the relative distance between the fourth stop plate 237 and the fourth gasket 233, the fourth preset angle can be set to any value.

[0065] The rollover mechanism 200 of this embodiment further includes a second connection gasket 240, two second fixing nuts 280 and two second nut columns 250 for fixing with the outside. The third rotating shaft 210 and the fourth rotating shaft 220 pass through the second connection gasket 240 respectively, so that the connection between the third rotating shaft 210 and the fourth rotating shaft 220 is more stable. The second fixing nut 80 fixes the second locking assembly 230 on the corresponding third rotating shaft 210 and the fourth rotating shaft 220. Specifically, the second fixing nut 280 presses the fourth gasket 233, the second locking gasket 232, the snap-fit ​​gasket, and the third gasket 231 on the stopper plate to realize the assembly of the fourth gasket 233, the second locking gasket 232, the snap-fit ​​gasket, and the third gasket 231. The second nut column 250 is installed on the second connection gasket 240, so that the rollover mechanism 200 can be fixed with the external mechanism through the nut column 250.

[0066] It should be noted that the third preset angle and the fourth preset angle of this embodiment are generally set to 90°, so that the secondary screen 5 can be Figure 4 After rotating 90° around the third rotating shaft 210, the main screen 4 forms an angle of 90°, and then rotates 90° around the fourth rotating shaft 220. Figure 5 As shown, it is located at the same horizontal plane as the main screen 4 to realize the screen splicing operation. Of course, the third preset angle and the fourth preset angle can also be set to other angles to meet the usage requirements of different occasions, which will not be repeated here.

[0067] See also Figure 1 , Figure 4 and Figure 5 , Figure 10-13As shown, in summary, the beneficial effects of the rollover mechanism 200 are: on the one hand, since the rotation of the two shafts is restricted by the second locking assembly 230 in turn, when one of the two shafts is in a rotating state, the other is in a stationary state, thereby realizing the switching of the rotatable shaft; on the other hand, the rotation restriction of the other shaft by the second locking assembly 230 can be released only when the shaft is rotated to a preset angle, so that different deployment states of the rollover mechanism 200 can be realized by setting different preset angles.

[0068] See also Figure 1 , Figure 14-16 As shown, in order to obtain a better screen splicing experience, the dual-screen splicing bracket 1000 of this embodiment also includes a sliding mechanism 300, which is installed on the fixed frame 1, and the main screen mounting seat 2 is slidably connected to the sliding mechanism 300 to drive the flat flip mechanism 100, the auxiliary screen mounting seat 3 and the side flip mechanism 200 to perform synchronous lifting and lowering movements relative to the fixed frame 1. The sliding mechanism 300 includes a slide rail assembly 310 and a slider assembly 320. The slide rail assembly 310 includes a slide rail 311 and a first slider 312. The slide rail 311 is installed on the fixed frame 1 in the vertical direction. The first slider 312 is slidably connected to the slide rail 311. The first slider 312 is connected to the main screen mounting seat 2. The main screen mounting seat 2 performs directional sliding on the slide rail 311 through the first slider 312, and drives the flat-flip mechanism 100, the auxiliary screen mounting seat 3 and the side-flip mechanism 200 to perform synchronous lifting and lowering movements relative to the fixed frame 1, so that the main screen mounting seat 2 and the auxiliary screen mounting seat 3 can perform synchronous lifting and lowering movements in the vertical direction to meet different usage scenarios.

[0069] The slider assembly 320 includes a fixing member 321, a second slider 322 and a first elastic member 323. The fixing member 321 is mounted on the fixing frame 1, the second slider 322 is connected to the main screen mounting seat 2, and the first elastic member 323 is respectively connected to the fixing member 321 and the second slider 322. The first elastic member 323 always has a tendency to pull the second slider 322 back to the fixing member 321. Preferably, the second slider 322 is a plastic member to reduce the weight of the second slider 322 and avoid affecting the sliding effect due to the excessive weight of the second slider 322.

[0070] The first elastic member 323 is a constant force spring, which is rolled up by a circle of spring sheets, and each circle of spring sheets is closely connected. Since the thickness of the spring sheet is relatively small relative to the diameter, the diameter does not change much when it is stretched, so the force required for stretching is basically the same, that is, when the constant force spring is stretched, the required force is relatively constant. The descent of the main screen mounting seat 2 is related to gravity, and the first elastic member 323 provides a vertical upward pulling force. On the one hand, when the main screen mounting seat 2 is in a free state, the first elastic member 323 buffers or offsets the gravity, so that the main screen mounting seat 2 will not fall autonomously; on the other hand, when the user pushes the main screen mounting seat 2 to fall, the user only needs to provide a stable thrust to push the main screen mounting seat 2 to fall, avoiding the need to provide different thrusts due to different elastic deformations of general springs, which greatly enhances the experience; on the other hand, when the main screen mounting seat 2 is subjected to external force and rapidly falls in the direction away from the fixing member 321, the elastic force of the first elastic member 323 can effectively buffer or offset the external force, avoiding damage to the main screen 4 due to rapid descent.

[0071] See also Figure 14-16 As shown, the slider assembly 320 of this embodiment further includes a snap-fit ​​assembly 324 , which is installed in the second slider 322 . The snap-fit ​​assembly 324 can be selectively snap-fitted and connected to the main screen mounting seat 2 .

[0072] Specifically, the snap-fit ​​assembly 324 includes a ball 3241 and a second elastic member 3242. The second slider 322 is provided with a first through hole 3221 for partially protruding the ball 3241. The second elastic member 3242 is preferably a pressure spring. The second elastic member 3242 is compressed in the second slider 322, and one end of the first elastic member 323 abuts against the inner wall of the second slider 322, and the other end abuts against the ball 3241. The second elastic member 3242 always provides a tendency to protrude the ball 3241 from the first through hole 3221. The main screen mounting seat is provided with a second through hole 21 corresponding to the first through hole 3221. When the main screen mounting seat is correctly installed on the fixing frame 1, the ball 3241 is embedded in the second through hole 21 and makes a click sound, reminding the user that the main screen mounting seat 2 is installed in place.

[0073] Preferably, the diameters of the first through hole 3221 and the second through hole 21 are smaller than the diameters of the ball 3241, so that the ball 3241 will not pop out of the second slider 322 under the elastic force of the second elastic member 3242. In addition, since the ball 3241 is a sphere, the cross-sectional area from the center of the ball 3241 to the surface of the ball 3241 will gradually decrease. In order to make the second through hole 21 better engage the ball 3241, the diameter of the first through hole 3221 is slightly larger than the diameter of the second through hole 21, so as to avoid a gap when the ball 3241 is embedded in the second through hole 21, so that when the ball 3241 is sequentially embedded in the first through hole 3221 and the corresponding second through hole 21, the main screen mounting seat is prevented from shaking due to the gap when the ball 3241 is embedded in the second through hole 21.

[0074] See also Figure 14-16 As shown, the sliding mechanism 300 of this embodiment further includes a guide plate 330, which is mounted on the fixing frame 1 and located between the fixing frame 1 and the main screen mounting seat 2, and the first slider 312 and the second slider 322 are respectively limited to slide on the guide plate 330. Specifically, the guide plate 330 is provided with a first guide groove 332 and a second guide groove 333, and the first guide groove 332 and the second guide groove 333 are both vertically opened downward, the first slider 312 is limited to slide in the first guide groove 332, and the second slider 322 is limited to slide in the second guide groove 333, thereby further preventing the first slider 312 and the second slider 322 from being damaged due to deviating from the preset sliding track.

[0075] See also Figure 14-18 As shown, when in use, after the auxiliary screen 3 rotates in the up-down direction to the plane where the main screen 4 is located, the second rotating shaft 120 can rotate. Therefore, at this time, Fig.17 As shown, the main screen mounting seat 2 is rotated upward so that the main screen 4 and the auxiliary screen 5 have a certain angle, and then the main screen mounting seat 2, the horizontal flip mechanism 100, the auxiliary screen mounting seat 3 and the side flip mechanism 200 are synchronously lowered relative to the fixing frame 1 through the sliding mechanism 300, so as to Fig.18 As shown, the main screen 4 is used as the bottom screen, so that the double-screen splicing bracket 1000 of this embodiment has more screen splicing methods.

[0076] See also Figure 1 , Figure 14-18As shown, in summary, the beneficial effects of the sliding mechanism 300 are: the first elastic member 323 is respectively connected to the fixing member 321 and the second slider 322, and the first elastic member 323 always has a tendency to pull the second slider 322 back to the fixing member 321. On the one hand, when the main screen mounting seat 2 slides in a direction away from the fixing member 321, it is necessary to overcome the elastic force of the first elastic member 323 to prevent the main screen mounting seat 2 from accidentally sliding in a direction away from the fixing member 321; on the other hand, when the main screen mounting seat 2 is subjected to external force and slides rapidly in a direction away from the fixing member 321, the elastic force of the first elastic member 323 can effectively buffer or offset the external force to prevent the main screen 4 from being damaged due to rapid sliding.

[0077] Combination Figure 1-Figure 18 The flat flipping mechanism 100 of the present invention is horizontally connected to the fixing frame 1, the main screen mounting seat 2 and the auxiliary screen mounting seat 3 are respectively connected to the flat flipping mechanism 100 which can be rotated up and down, and the auxiliary screen mounting seat 3 can be rotated to the plane where the main screen mounting seat 2 is located, so that the auxiliary screen 5 can be spliced ​​with the main screen 4 by rotating up and down; the side flipping mechanism 200 is connected to the bending part 31 which can be rotated left and right in the vertical direction, and the auxiliary screen 5 is connected to the side flipping mechanism 200 which can be rotated left and right, and the auxiliary screen 5 can be rotated to the plane where the main screen mounting seat 2 is located, so that the auxiliary screen 5 can be spliced ​​with the main screen 4 by rotating left and right, so that the double-screen splicing bracket 1000 of the present invention has the function of splicing screens from the top and bottom or left and right directions respectively, so that more splicing needs can be met by a single bracket.

[0078] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
