DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear and obvious, the following will be combined with the attached drawings to make a further description. Figures 1-11Further detailed description of the present utility model is made in combination with Embodiments 1-2. It should be understood that the specific embodiments described herein are only used to explain the present utility model and not used to limit the present utility model.

[0029] Embodiment 1,

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , a non-polarity track splicing screen comprises a mounting frame 1, a plurality of display screens 2 and a non-polarity power supply 3, the non-polarity power supply 3 is fixedly arranged on the mounting frame 1, a sliding track 11 is formed at the bottom end of the mounting frame 1, and the plurality of display screens 2 are clamped and installed in the sliding track 11. The display screens 2 can be slid on the sliding track 11 by manually pushing the display screens 2. A metal conductive strip 12 is arranged in the sliding track 11, the metal conductive strip 12 is made of copper material, the metal conductive strip 12 made of copper material has good conductivity and low resistivity, and in addition, the copper material has high mechanical strength and toughness and can maintain stable physical properties in different environments.

[0031] The metal conductive strip 12 is electrically connected with the non-polarity power supply 3, and a conductive contact 21 is arranged at the top end of the display screen 2 in correspondence. After the display screen 2 is clamped and installed in the sliding track 11, the conductive contact 21 at the top end of the display screen 2 abuts against the metal conductive strip 12 in the sliding track 11, so that the display screen 2 is powered. The non-polarity power supply 3 makes it unnecessary to consider the installation direction of the display screen 2 when installing the display screen 2 at the bottom end of the mounting frame 1, thereby facilitating the installation between the display screen 2 and the mounting frame 1, and in addition, the design of the non-polarity power supply 3 improves the convenience and safety of power supply use.

[0032] Referring to Figure 1 and Figure 4 , a control panel 22 and a pair of photosensitive sensors 23 are arranged in the display screen 2, the two photosensitive sensors 23 are electrically connected with the control panel 22, and the control panel 22 is electrically connected with the non-limit power supply. Light transmission holes 24 are formed in the two side surfaces of the display screen 2, and the two photosensitive sensors 23 are arranged at the light transmission holes 24. When it is necessary to increase the screen display, the number of display screens 2 installed on the sliding track 11 is increased, the display screens 2 are pushed to slide on the sliding track 11 of the mounting frame 1, and the adjacent two display screens 2 are made to approach each other. When the adjacent two display screens 2 abut against each other, the photosensitive sensor 23 in the display screen 2 cannot sense the external light through the light transmission hole 24. The photosensitive sensor 23 transmits the sensed information to the control panel 22, so that the display screens 2 form a large display picture. The non-polarity track splicing screen combines the advantages of seamless splicing technology and non-polarity power supply 3 design, and provides a more convenient, efficient and flexible display solution for users.

[0033] With reference to Figures 5-8 , in order to facilitate the detachable installation of each display screen 2 in the sliding rail 11 of the mounting frame 1, a mounting slot 25 is formed at the top end of each display screen 2, and a pair of limiting plates 251 are arranged in parallel in the mounting slot 25, so that a sliding groove 252 is formed between the two limiting plates 251. A clamping hole 26 is formed on the front and back of the display screen 2, so that the two clamping holes 26 are respectively communicated with the two ends of the sliding groove 252. A spring 27, an L-shaped sliding plate 28 and a pair of buckles 29 are arranged in the mounting slot 25, the L-shaped sliding plate 28 includes a horizontal plate 281 and a vertical plate 282, and a pair of limiting grooves 283 are formed through the horizontal plate 281, the two limiting grooves 283 are distributed in a spreader shape on the horizontal plate 281, and the distance between the two limiting grooves 283 gradually decreases from the end away from the vertical plate 282 to the end close to the vertical plate 282. The two buckles 29 are arranged in the sliding groove 252 and can be respectively inserted from the clamping holes 26 on both sides of the display screen 2; in order to facilitate the sliding of the two buckles 29 in the sliding groove 252, a limiting column 291 is vertically fixed on the two buckles 29, and the limiting column 291 on the two buckles 29 is respectively inserted into the two limiting grooves 283 of the horizontal plate 281. Push the L-shaped sliding plate 28 to move in the mounting slot 25 towards the end wall of the mounting slot 25, so that the two limiting columns 291 drive the buckles 29 to slide into the sliding groove 252 under the action of the L-shaped sliding plate 28, so that the buckles 29 are hidden in the sliding groove 252.

[0034] After the top end of the display screen 2 is inserted into the sliding rail 11 of the mounting frame 1, in order to make the two buckles 29 automatically inserted from the clamping hole 26, so as to be clamped and installed with the sliding rail 11 of the mounting frame 1. One end of the spring 27 is fixed with the end wall of the mounting slot 25, and a fixed plate 284 is vertically fixed on the side of the horizontal plate 281 away from the vertical plate 282, so that the fixed plate 284 is parallel to the vertical plate 282, a positioning column 285 is fixed on the surface of the fixed plate 284, the positioning column 285 is arranged in a horizontal state, the other end of the spring 27 is sleeved on the periphery of the positioning column 285 and is fixed with the fixed plate 284. The setting of the fixed plate 284 facilitates the abutment of the end of the spring 27, and the spring 27 is extruded when the L-shaped sliding plate 28 is pushed; the setting of the positioning column 285 makes the spring 27 keep stable position during extrusion, so as to avoid the deviation of the spring 27.

[0035] When it is needed to install the display screen 2 and the sliding rail 11 of the mounting frame 1, the L-shaped sliding plate 28 is pushed to slide towards the end wall of the mounting groove 25, and the L-shaped sliding plate 28 slides to drive the limiting column 291 and the buckle 29 to slide towards the inside of the sliding groove 252 in the process of sliding, until the buckle 29 is completely hidden in the sliding groove 252 and the clamping hole 26. Then the top end of the display screen 2 can be clamped and installed into the sliding rail 11, and the L-shaped sliding plate 28 slides towards the end wall of the mounting groove 25 in the process of sliding, so that the fixed plate 284 presses the spring 27. After the display screen 2 is clamped and installed into the sliding rail 11, the L-shaped sliding plate 28 is stopped from being pushed, so that the L-shaped sliding plate 28 slides towards the outside of the display screen 2 under the elastic force of the spring 27, so as to drive the buckle 29 to pass out of the clamping hole 26 and be clamped with the sliding rail 11, thereby making the installation between the display screen 2 and the mounting frame 1 stable.

[0036] The two limiting plates 251 in the mounting groove 25 are arranged to make the buckle 29 slide in the sliding groove 252 between the two limiting plates 251, and the arrangement of the two limiting plates 251 plays a limiting role on the buckle 29. This prevents the buckle 29 from being angularly offset after entering the mounting groove 25, so as to prevent the buckle 29 from being clamped with the side wall of the mounting groove 25 and thus being unable to smoothly pass out of the clamping hole 26 under the elastic force of the spring 27.

[0037] Referring to Figure 9 and Figure 10 In order to facilitate the spliced screen to fully display information, the mounting frame 1 is arranged in a square shape, the steel wire ropes 4 are connected with the mounting frame 1, and the mounting frame 1 is suspended and installed by the steel wire ropes 4. For this purpose, an external thread sleeve 5 is fixedly arranged at each end corner of the mounting frame 1, a fixed block 7 is fixedly arranged at one end of the steel wire rope 4, and the fixed block 7 connected with the steel wire rope 4 is arranged in the external thread sleeve 5. A cover-shaped nut 6 is threadedly connected with the external thread sleeve 5, a through hole 61 is formed in the top end of the cover-shaped nut 6, the steel wire rope 4 passes through the through hole 61 of the cover-shaped nut 6, and the connection and installation between the steel wire rope 4 and the mounting frame 1 are completed. The cover-shaped nut 6 and the external thread sleeve 5 are matched and installed, so that the steel wire rope 4 and the mounting frame 1 can be disassembled, different lengths of steel wire ropes 4 can be replaced, and the display requirements of the spliced screen in different scenes can be met.

[0038] The specific implementation principle of the embodiment of the application is that when the non-polarity track spliced screen is needed to be used, according to the needs of the use scene, the fixed block 7 at the end of the steel wire rope 4 is arranged in the external thread sleeve 5, the steel wire rope 4 passes through the through hole 61, and the cover-shaped nut 6 and the external thread sleeve 5 are threadedly connected. In this way, the fixed block 7 is limited between the cover-shaped nut 6 and the external thread sleeve 5, and the mounting frame 1 is horizontally suspended by the steel wire ropes 4.

[0039] Subsequently, several display screens 2 to be installed are taken out, and each display screen 2 is installed into the sliding rail 11 at the bottom end of the mounting rack 1. When installing, the L-shaped sliding plate member 28 is pushed towards the end wall of the installation slot 25 to extrude the spring 27. The buckle 29 moves towards the inside of the sliding groove 252 under the action of the limiting groove 283 and the limiting column 291, and is hidden in the sliding groove 252. After the display screen 2 is clamped and installed into the sliding rail 11, the pushing of the L-shaped sliding plate member 28 is stopped, so that the L-shaped sliding plate member 28 slides to the outside of the display screen 2 under the action of the spring 27. In this way, the buckle 29 is pulled out of the clamping hole 26 and clamped with the sliding rail 11, so that the display screen 2 is stably installed with the mounting rack 1. The two limiting plates 251 in the installation slot 25 are arranged to limit the movement of the buckle 29, so as to prevent the buckle 29 from being clamped with the side wall of the installation slot 25 due to angular deviation, thereby preventing the buckle 29 from being pulled out of the clamping hole 26.

[0040] After each display screen 2 is installed into the sliding rail 11 at the bottom end of the mounting rack 1, the conductive contact 21 at the top end of the display screen 2 abuts against the metal strip 12 in the sliding rail 11. The non-polar power supply 3 is used for power supply, so that each display screen 2 does not need to consider the installation direction of the display screen 2 when installed at the bottom end of the mounting rack 1. In this way, the installation between each display screen 2 and the mounting rack 1 is facilitated, and the convenience and safety of power supply are improved by the design of the non-polar power supply 3. Each display screen 2 is moved towards each other until the adjacent two display screens 2 abut against each other, so that the photosensitive sensor 23 cannot sense external light through the light transmission hole 24. The photosensitive sensor 23 transmits the sensed information to the control panel 22, so that each display screen 2 forms a large display picture.

[0041] Embodiment 2,

[0042] Referring to Figure 11 The difference from embodiment 1 is that the spring 27 is arranged in the sliding groove 252, so that the two ends of the spring 27 are fixed with the buckle 29; and the outer surface of the buckle 29 is arranged as an inclined surface 292, so that the length of the upper end of the buckle 29 is smaller than the length of the lower end. When installing the display screen 2, the top end of the display screen 2 is directly clamped and installed into the sliding rail 11 of the mounting rack 1. During the installation process, the outer surface of the buckle 29 is extruded by the bottom end of the sliding rail 11, so that the two buckles 29 compress the spring 27 until the two buckles 29 completely slide into the sliding groove 252. After the top end of the display screen 2 is installed into the sliding rail 11, the two buckles 29 are pulled out of the clamping hole 26 under the action of the spring 27, so as to be clamped with the sliding rail 11. Also, the limiting column 291 is vertically and fixedly arranged on the buckle 29. The limiting column 291 limits the movement of the buckle 29, so as to prevent the buckle 29 from completely sliding out of the clamping hole 26 and falling off.

[0043] The utility model has been described above in conjunction with the drawings, obviously, the utility model specific implementation is not limited by the above-mentioned mode, as long as various non-essential improvements of method concept and technical scheme of adopting the utility model or the utility model concept and technical scheme are directly applied to other occasions without improvement, all are in the protection of the utility model.
