[0021] The present application provides a concealed multi-dimensional positioning pin, comprising a sliding rail 101 and a positioning assembly, the positioning assembly comprises a sliding block 103, a pin column 104, a screw rod 105, two positioning members 106 and two blocking members 107; the positioning member 106 comprises an outer column 108, a spring 109, a pin rod 110, a limiting block 111 and a buffer pad 112; the blocking member 107 comprises a baffle 113 and a connecting bolt 114; the foregoing scheme can prevent the collision of two LED screen doors moving towards each other, and avoid the damage of the LED screen door.

[0022] For this specific embodiment, the slide rail 101 has a slide groove 102 at the bottom of the slide rail 101; the sliding block 103 is in sliding connection with the slide rail 101 and is located in the slide groove 102; the pin column 104 is fixedly connected with the sliding block 103 and is located at the bottom of the sliding block 103; the screw rod 105 is fixedly connected with the pin column 104 and is located at the bottom of the pin column 104; two positioning members 106 are mirror image arranged on both sides of the sliding block 103; two blocking members 107 are mirror image arranged on both sides of the slide rail 101. In use, mounting holes are opened on the ground, the screw rod 105 is fixedly installed in the mounting holes on the ground, the pin column 104 is on the ground, the slide groove 102 is matched with the sliding block 103, the slide rail 101 is butt jointed with the sliding block 103 and the pin column 104, the sliding block 103 is in the slide groove 102, then the two blocking members 107 are installed on both sides of the slide rail 101, and finally the LED screen door is fixedly installed on the top of the slide rail 101. When the driving mechanism drives the two LED screen doors to move towards each other, the slide rail 101 moves along the sliding block 103, the sliding block 103 provides guidance for the movement of the slide rail 101, avoids misalignment of the two LED screen doors when they are closed, and when the two LED screen doors are just closed, the positioning member 106 will be in contact with the blocking member 107, limiting the continuous movement of the slide rail 101, so as to prevent the two moving LED screen doors from moving too much when the control system fails, and to avoid damage caused by collision between the two moving LED screen doors. The installation positions of the stud, the pin column 104, the sliding block 103 and the positioning member 106 on the ground are calculated and determined according to the actual position of the LED screen door to be moved; the stud, the pin column 104, the sliding block 103 and the positioning member 106 are all surrounded by the slide rail 101, so they cannot be seen from the outside and are not easily damaged, and they are also relatively beautiful; the sliding block 103 can position the front and back and up and down positions of the slide rail 101, so as to multi-dimensionally position the LED screen door and avoid misalignment when the LED screen door moves; in the above manner, collision between the two moving LED screen doors can be prevented, and the LED screen door can be prevented from being damaged.

[0023] The outer column 108 and the sliding block 103 are fixedly connected and located at the side of the sliding block 103; the spring 109 and the outer column 108 are fixedly connected and located inside the outer column 108; the pin rod 110 and the spring 109 are fixedly connected and slidably connected with the outer column 108 and located at the side of the spring 109. The outer column 108 provides a guide for the spring 109 and the pin rod 110. When the two LED screen doors are just closed, the pin rod 110 will be in contact with the blocking piece 107, the spring 109 will be contracted under stress, and the movement of the sliding rail 101 is limited, thereby preventing the two moving LED screen doors from moving too much and being damaged due to collision when the control system fails. The spring 109 can provide a buffering effect to prevent the pin rod 110 and the blocking piece 107 from being damaged due to excessive impact force.

[0024] Secondly, the limiting block 111 and the pin rod 110 are fixedly connected and located at the side of the pin rod 110. During the closing of the two LED screen doors, the pin rod 110 will be in contact with the blocking piece 107, the spring 109 will be contracted under stress, and the pin rod 110 will move towards the inside of the outer column 108 until the limiting block 111 is in contact with the outer column 108, thereby limiting the movement of the sliding rail 101.

[0025] Meanwhile, the buffer pad 112 and the pin rod 110 are fixedly connected and located on the side of the pin rod 110 away from the spring 109. When the pin rod 110 is in contact with the blocking piece 107, the buffer pad 112 can provide a buffering effect.

[0026] In addition, the baffle 113 is located at the side of the sliding rail 101; the connecting bolt 114 and the baffle 113 are threadedly connected and threadedly connected with the sliding rail 101 and located at the side of the baffle 113. The baffle 113 cooperates with the pin rod 110 to limit the movement distance of the LED screen door, and the connecting bolt 114 can be used to install the baffle 113 on the sliding rail 101, so as to facilitate the installation and disassembly of the baffle 113.

[0027] In use of the utility model, the installation hole is opened on the ground, the screw rod 105 is fixedly installed in the installation hole on the ground, the sliding groove 102 is matched with the sliding block 103, the sliding rail 101 is butted with the sliding block 103 and the pin column 104, the sliding block 103 is in the sliding groove 102, then the two baffle plates 113 are installed on both sides of the sliding rail 101 through the connecting bolt 114, finally the LED screen door is fixedly installed on the top of the sliding rail 101, when the driving mechanism drives the two LED screen doors to move towards each other, the sliding rail 101 moves along the sliding block 103, the sliding block 103 provides the direction for the movement of the sliding rail 101, avoids the dislocation of the two LED screen doors when closing, in the process of closing of the two LED screen doors, the buffer pad 112 will first abut against the baffle plate 113, the spring 109 is contracted under stress, the pin rod 110 will move towards the outer column 108, until the limiting block 111 abuts against the outer column 108, the continuous movement of the sliding rail 101 is limited, at this time, the two LED screen doors just complete closing, so that the excessive movement of the two moving LED screen doors towards each other can be prevented when the control system fails, and the two moving LED screen doors towards each other can be prevented from being damaged by collision. The screw column, the pin column 104, the sliding block 103 and the positioning piece 106 are installed on the ground, and the installation positions are calculated and determined according to the actual position of the LED screen door to be moved. The spring 109 can provide a buffering effect, avoiding damage caused by excessive impact force of the pin rod 110 and the blocking piece 107. The sliding block 103 can position the front and back and up and down positions of the sliding rail 101, so that the LED screen door can be multi-dimensionally positioned, avoiding dislocation when the LED screen door moves.
