[0037] 1 to 9 , a first embodiment of the present invention provides a safety lock structure 100, including a first connecting arm 110, a second connecting arm 120, an adapter assembly 130, and a bolt assembly 140; the second connecting arm 120 is formed with a slide groove 121; the adapter assembly 130 is located between the first connecting arm 110 and the second connecting arm 120, and the adapter assembly 130 includes an adapter 131, a lock core 132, and a first elastic member 133. The two sides of the adapter 131 are respectively rotatably connected to the first connecting arm 110 and the second connecting arm 120, and the two ends of the first elastic member 133 are respectively abutted against the adapter 131 and the lock core 132. 2. The locking bolt assembly 140 is located on the second connecting arm 120. The locking bolt assembly 140 includes a locking rod 141, a locking head 142 and a second elastic member 143. The two ends of the second elastic member 143 are respectively in contact with the locking head 142 and the locking rod 141. The locking head 142 slides in the sliding groove 121. The locking rod 141 is formed with a first locking groove 1411 and a second locking groove 1412. The locking rod 141 is inserted into and removed from the first connecting arm 110. When the locking rod 141 is inserted into the first connecting arm 110, the lock core 132 is engaged with the first locking groove 1411; when the locking rod 141 is pulled out of the first connecting arm 110, the locking head 142 is engaged with the second locking groove 1412.In a specific application, since the two sides of the adapter 131 are rotatably connected to the first connecting arm 110 and the second connecting arm 120 respectively, the two ends of the first elastic member 133 are respectively in contact with the adapter 131 and the lock core 132; the two ends of the second elastic member 143 are respectively in contact with the lock head 142 and the lock rod 141, the lock head 142 slides in the slide groove 121, and the lock rod 141 is formed with a first lock groove 1411 and a second lock groove 1412. The lock rod 141 is inserted and removed from the first connecting arm 110. When When the locking rod 141 is inserted from the second connecting arm 120 to the first connecting arm 110, the first locking groove 1411 of the locking rod 141 reaches the adapter 131, and since the two ends of the first elastic member 133 respectively abut on the adapter 131 and the lock core 132, the lock core 132 abuts on the first locking groove 1411, so that the lock core 132 locks the locking rod 141 between the first connecting arm 110 and the second connecting arm 120. In this way, the first connecting arm 110 and the second connecting arm 120 can be locked. When the second connecting arm 120 is unlocked, the lock head 142 is locked in the second locking groove 1412, and the second connecting arm 120 is locked.

[0038] In a possible embodiment, the second connecting arm 120 also forms a limiting groove 122, which is connected to the sliding groove 121 at an angle. When the locking rod 141 is pulled out of the first connecting arm 110 and the second locking groove 1412 coincides with the limiting groove 122, the lock head 142 is engaged with the second locking groove 1412. In a specific application, the limiting groove 122 of the second connecting arm 120 is located at the end of the slide groove 121, and the limiting groove 122 is connected to the slide groove 121 at an angle. When the lock head 142 reaches the limiting groove 122, under the action of the second elastic member 143, the lock head 142 is pushed into the second lock groove 1412, so that the lock head 142 is clamped on the limiting groove 122 set at an angle to the slide groove 121, so that the lock head 142 cannot slide relative to the slide groove 121, thereby locking the locking rod 141 on the second connecting arm 120, wherein the angle between the limiting groove 122 and the slide groove 121 can be an acute angle or a right angle. Preferably, the angle between the limiting groove 122 and the slide groove 121 is a right angle.

[0039] In one possible embodiment, the adapter 131 is formed with an escape groove 1311, which coincides with the first lock groove 1411. The lock core 132 is slidably connected to the escape groove 1311. When the lock core 132 disengages from the first lock groove 1411 and enters the escape groove 1311, the lock rod 141 is pulled out of the first connecting arm 110. In a specific application, the escape groove 1311 formed on the adapter 131 coincides with the first lock groove 1411. When the lock core 132 disengages from the first lock groove 1411 and enters the escape groove 1311, the lock rod 141 can be pulled out of the first connecting arm 110 and into the second connecting arm 120. In addition, the escape groove 1311 is located below the first lock groove 1411. In this way, when the lock core 132 exits the first lock groove 1411, it can quickly enter the escape groove 1311, thereby completing the unlocking of the lock core 132 at the escape groove 1311.

[0040] In a possible implementation, the lock core 132 includes a card body 1321 and a lever 1322 . The lever 1322 is disposed away from the card body 1321 and slides in the avoidance groove 1311 . The card body 1321 is used to engage with the first lock groove 1411 . In a specific application, the lever 1322 is set away from the card body 1321, and the card body 1321 is used to engage the first lock slot 1411. When the lever 1322 slides out from the first lock slot 1411 to the avoidance slot 1311, the lock core 132 releases the lock on the first lock slot 1411. When the lever 1322 slides from the avoidance slot 1311 into the first lock slot 1411, the lock core 132 locks the first lock slot 1411. The lever 1322 is connected to the lock core 132 and is located on the outside of the first lock slot 1411. The lock core 132 can be conveniently operated to lock or unlock the first lock slot 1411 through the lever 1322.

[0041] In one possible embodiment, the first connecting arm 110 is formed with a first socket 111, the second connecting arm 120 is formed with a second socket 123, and the second socket 123 is connected to the slide groove 121, and the locking rod 141 is inserted into the first socket 111 and the second socket 123 to limit the rotation of the first connecting arm 110 relative to the second connecting arm 120; or the locking rod 141 is inserted into the second socket 123 to release the restriction on the rotation of the first connecting arm 110 relative to the second connecting arm 120. In specific applications, in order to enable the locking rod 141 to be plugged into and out of the first socket 111 and the second socket 123, the first connecting arm 110 is formed with a first socket 111, and the second connecting arm 120 is formed with a second socket 123. When the rod is inserted into the first socket 111 and the second socket 123, the first connecting arm 110 and the second connecting arm 120 can be locked, thereby limiting the rotation of the first connecting arm 110 relative to the second connecting arm 120. When the rod is only inserted into the second socket 123, the lock of the first connecting arm 110 and the second connecting arm 120 can be released, so that the first connecting arm 110 can rotate relative to the second connecting arm 120, wherein the first socket 111 and the second socket 123 are respectively transitionally matched with the locking rod 141, so that the first connecting arm 110 and the second connecting arm 120 are stable after being locked and will not shake.

[0042] In one possible embodiment, the adapter 131 is further formed with a third socket 1312, which is opposite to the first socket 111 and the second socket 123, and is located between the first socket 111 and the second socket 123 for the locking rod 141 to pass through. In a specific application, in order to facilitate the connection between the locking rod 141 and the first socket 111 and the second socket 123, the adapter 131 is formed with the third socket 1312, which is located between the first socket 111 and the second socket 123 for the locking rod 141 to pass through. Since the third socket 1312 is arranged opposite to the first socket 111 and the second socket 123, the third socket 1312 can be received between the first socket 111 and the second socket 123, thereby improving the docking performance of the locking rod 141 with the first socket 111 and the second socket 123.

[0043] In one possible embodiment, the second connecting arm 120 is provided with a protruding slide 124 on the inner wall of the second insertion hole 123, and at least two slides 124 abut against both sides of the locking rod 141. In a specific application, in order to improve the smoothness of the sliding of the locking rod 141 in the second insertion hole 123, a protruding slide 124 is provided on the inner wall of the second connecting arm 120, and the two slides 124 are located on both sides of the second insertion hole 123. Since the slides 124 reduce the contact area between the locking rod 141 and the second insertion hole 123, the friction force of the locking rod 141 on the second insertion hole 123 is reduced, thereby improving the smoothness of the sliding of the locking rod 141 on the second insertion hole 123. It is easy to understand that the first connecting arm 110 can also be provided with a corresponding slide 124 on the inner wall of the first insertion hole 111 to reduce the friction force of the locking rod 141 on the first insertion hole 111. Example 2

[0044] The subject matter protected by the second embodiment is different from that of the first embodiment, specifically:

[0045] Referring to Figures 9 and 10 , a second embodiment of the present invention further provides a folding mechanism 10 comprising the aforementioned safety lock structure 100 and a folding frame 200, wherein the folding frame 200 is rotatably connected to the first connecting arm 110 and the second connecting arm 120. In a specific application, the first connecting arm 110 and the second connecting arm 120 are rotatably connected via the safety lock structure 100. When the safety lock structure 100 locks the first connecting arm 110 and the second connecting arm 120, the first connecting arm 110 and the second connecting arm 120 restrict the rotation of the folding frame 200.

[0046] In one possible embodiment, the folding frame 200 includes a first mounting frame 210 and a second mounting frame 220. The first mounting frame 210 is provided with a safety lock structure 100. The second mounting frame 220 is detachably connected to the first mounting frame, and the first mounting frame 210 is folded by the safety lock structure 100. In a specific application, the detachable connection between the second mounting frame 220 and the first mounting frame 210 can reduce the complexity of assembling the folding frame 200. The folding of the first mounting frame 210 by the safety lock structure 100 can improve the stability of the first mounting frame 210. Therefore, by simplifying the connection between the second mounting frame 220 and the first mounting frame 210 and improving the folding stability of the first mounting frame 210, the usability of the folding frame 200 can be improved and the production cost can be reduced. Of course, the safety lock structure 100 can also be used on the second mounting frame 220 to realize the folding of the second mounting frame 220. Example 3

[0047] The subject matter protected by the third embodiment is different from that of the first embodiment, specifically:

[0048] 10 and 11 , the second embodiment of the present invention further provides a functional device 1, comprising the aforementioned folding mechanism 10 and a functional module 20, wherein the functional module 20 is connected to a first mounting frame 210. In a specific application, a plurality of functional modules 20 are connected to the first mounting frame 210.
