[0036] In addition, the meaning of the term "plurality" should be two or more.
[0037] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the accompanying drawings and combine the embodiments to detail this application.
[0038] As Figures 1-9 shown, an electromagnetic mechanical lock for a virtual shooting studio includes a first lock body 1 fixedly arranged on a first moving screen 15 and a second lock body 2 fixedly arranged on a second moving screen 16;
[0039] The first lock body 1 includes a main frame 101, a magnetic attraction groove 108 formed on the main frame 101, an electromagnet 103 fixedly arranged in the magnetic attraction groove 108, and a lock hole 107 formed on the main frame 101 and communicating with the magnetic attraction groove 108;
[0040] The second lock body 2 includes a mounting plate 206, a magnetic attraction iron plate 202 fixedly arranged on the mounting plate 206 and cooperating with the magnetic attraction groove 108, and a lock shaft 201 fixedly arranged on the magnetic attraction iron plate 202 and cooperating with the lock hole 107. Clamping platforms 207 are respectively and fixedly arranged on both sides of the magnetic attraction iron plate 202, and a magnetic attraction surface 208 is provided on the magnetic attraction iron plate 202;
[0041] At least one set of adjusting mechanisms for adjusting the position of the magnetic attraction iron plate 202 in the magnetic attraction groove 108 is arranged on the main frame 101. Each set of adjusting mechanisms includes an upper adjusting bolt 102 and a lower adjusting bolt 113 located on the upper and lower sides of the magnetic attraction groove 108 respectively. Both the upper adjusting bolt 102 and the lower adjusting bolt 113 are in threaded cooperation with the main frame 101.
[0042] In order to ensure the stability of the electromagnetic mechanical lock and prevent misoperation, a safety structure is arranged on the first lock body 1. The safety structure includes a safety catch lock 105 slidably arranged on the main frame 101. An annular safety lock groove 203 cooperating with the end of the safety catch lock 105 is formed on the lock shaft 201. A reset elastic member 110 is sleeved on the safety catch lock 105. Specifically: a chute 111 cooperating with the safety catch lock 105 is arranged on the main frame 101. The two ends of the wide head at the front of the safety catch lock 105 are respectively arranged in the chute 111, and the other end has a convex platform 112. The reset elastic member 110 is concentrically installed with the convex platform 112. At this time, one end of the elastic member abuts against the bottom of the convex platform 112, and the other end abuts against the neck of the safety catch lock 105. When an external force pulls the safety catch lock 105 to slide along the chute 111, overcoming the action of the reset elastic member 110, the safety catch lock 105 slides open and disengages from the annular safety lock groove 203 on the lock shaft 201. When the external force disappears, the safety catch lock 105 returns to its position and locks under the action of the reset elastic member 110.
[0043] In order to facilitate the insertion of the lock shaft 201 into the lock hole 107 for locking, the end of the lock shaft 201 has a tapered portion 205.
[0044] In order to facilitate the control of the electromagnet, an electromagnetic control switch 104 electrically connected to the electromagnet 103 is further included. Further preferably, there are two groups of electromagnets 103, and two groups of electromagnetic control switches 104 are correspondingly arranged.
[0045] In order to improve the overall stability of the electromagnetic mechanical lock, there are two sets of the adjusting mechanism, and the two sets of the adjusting mechanism are symmetrically arranged with the lock hole 107 as the center.
[0046] In order to prevent the adjusting bolts from scratching the surface of the magnetic attraction iron plate 202 during adjustment, universal ball steel beads 106 are arranged at the bottoms of the upper adjusting bolt 102 and the lower adjusting bolt 113.
[0047] Preferably in this embodiment, the first lock body 1 and the truss of the first moving screen 15 are fixedly connected through a first fastener, and the second lock body 2 and the side truss of the second moving screen 16 are fixedly connected through a second fastener. The first fastener is matched with the installation screw hole 109, and the second fastener is matched with the fixing screw hole 204.
[0048] During the operation process, turn on the electromagnetic control switch 104 on the first lock body 1, and push the two LED moving screens to approach and join at the side. When the lock shaft 201 on the second lock body 2 is inserted into the lock hole 107 on the first lock body 1, due to the coaxial center fit, the two LED moving screens can achieve concentric positioning. At the same time, when the magnetic attraction iron plate 202 approaches the magnetic attraction groove 108, by rotating the positions of the four groups of adjusting bolts, the universal ball steel beads 106 are made to press against the upper and lower surfaces of the magnetic attraction iron plate 202, and the magnetic attraction iron plate 202 is adjusted to be parallel to the magnetic attraction groove 108. Under the action of the magnetic force and the rollers of the universal ball steel beads 106, the magnetic attraction iron plate 202 can automatically slide into the magnetic attraction groove 108, so that the first lock body 1 and the second lock body 2 are seamlessly attracted and combined, thereby realizing seamless splicing between the LED moving screen devices. During this process, when the tapered tip of the lock shaft 201 passes through the lock hole 107, the safety catch lock 105 on the back of the first lock body 1 is pushed to slide along the chute 111. After the first lock body 1 and the second lock body 2 are seamlessly attracted and combined, under the action of the reset elastic member 110, the safety catch lock 105 rebounds and snaps into the annular safety lock groove 203 on the lock shaft 201 to complete mechanical locking, preventing the gap from being disengaged due to the disappearance of the magnetic force and realizing firm and seamless splicing.
[0049] As Figures 10-11 shown, this embodiment also provides a virtual shooting studio, which includes a plurality of moving screens, and adjacent moving screens are connected through the above-mentioned electromagnetic mechanical lock for the virtual shooting studio.
[0050] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
