[0021] This utility model provides a simple unlocking structure, including a connecting pipe 101, a lock mounting bracket 102, and a lock assembly. The connecting pipe 101 is welded to the lock mounting bracket 102 and passes through the lock mounting bracket 102. The lock assembly is detachably connected to the lock mounting bracket 102 and is located inside the lock mounting bracket 102.
[0022] The system also includes a lock assembly, which comprises an unlocking pull strap 103, a limiting wire 104, a first fixing plate 105, a second fixing plate 106, a fixing component, and a stabilizing component. The limiting wire 104 is welded to the lock mounting bracket 102 and is located above the lock mounting bracket 102. The unlocking pull strap 103 is slidably connected to the limiting wire 104 and wraps around the limiting wire 104. The first fixing plate 105 is fixedly connected to the lock mounting bracket 102 and is located inside the lock mounting bracket 102. The second fixing plate 106 is fixedly connected to the lock mounting bracket 102 and is located inside the lock mounting bracket 102. The fixing component is disposed between the first fixing plate 105 and the second fixing plate 106. The stabilizing component is disposed inside the lock mounting bracket 102.
[0023] In this embodiment, the limiting wire 104 restricts the movement range of the unlocking pull strap 103 to prevent the movement of the pull strap from exceeding the movement range. The lock mounting bracket 102 fixes the positions of the first fixing plate 105 and the second fixing plate 106, and the first fixing plate 105 and the second fixing plate 106 fix the position of the fixing component. Pulling the unlocking pull strap 103 enables the fixing component to be unlocked.
[0024] Furthermore, the lock assembly also includes a locking wire 107, which engages with the fixing component and is located at the lower end of the fixing component.
[0025] In this embodiment, pulling the unlocking strap 103 unlocks the fixing component, allowing it to disengage from the locking wire 107. Pushing the locking wire 107 engages it in the fixing component for locking.
[0026] Further, the fixing component includes an unlocking wire 108, a first rotating rod 109, an unlocking plate 110, a second rotating rod 111, a limiting protrusion 112, a locking plate 113, and a limiting recess 114. One end of the unlocking wire 108 is detachably connected to the unlocking pull strap 103 and is located at one end of the unlocking pull strap 103. The unlocking plate 110 is rotatably connected to the unlocking wire 108 and wraps around the unlocking wire 108. The unlocking plate 110 is located away from the unlocking wire 108. At one end of the locking strap 103, the first rotating rod 109 is rotatably connected to the unlocking piece 110 and passes through the first fixing plate 105, the second fixing plate 106 and the unlocking piece 110. The limiting protrusion 112 is disposed on the surface of the unlocking piece 110. The second rotating rod 111 is rotatably connected to the locking piece 113 and passes through the first fixing plate 105, the second fixing plate 106 and the locking piece 113. The limiting recess 114 is disposed on the surface of the locking piece 113.
[0027] In this embodiment, the unlocking wire 108 drives the unlocking plate 110, causing the unlocking plate 110 to rotate. Simultaneously, the limiting protrusion 112 on the unlocking plate 110 disengages from the limiting recess 114 on the locking plate 113, allowing the locking plate 113 to rotate freely. The rotation of the unlocking plate 110 also stretches the return spring 115, causing it to be under force. This force causes the return spring 115 to drive the locking plate 113 to rotate, simultaneously pushing the locking wire 107 out, thus unlocking the plate. Similarly, the advancement of the locking wire 107 causes the locking plate 113 to rotate, stretching the return spring 115 and causing it to pull the unlocking plate 110 to rotate. The rotation of the unlocking plate 110 causes the limiting protrusion 112 on the unlocking plate 110 to cooperate with the limiting recess 114 on the locking plate 113, restricting rotation and thus achieving locking.
[0028] Furthermore, the fixing component also includes a return spring 115, one end of which is fixedly connected to the unlocking piece 110 and located between the unlocking piece 110 and the locking piece 113, and the end of the return spring 115 away from the unlocking piece 110 is fixedly connected to the locking piece 113.
[0029] In this embodiment, the reset spring 115 can drive the unlocking piece 110 to rotate, so that the fixing component can be locked.
[0030] Furthermore, the stabilizing component includes a stabilizing plate 116, which is fixedly connected to the first fixing plate 105 and wraps around the first rotating rod 109 and the second rotating rod 111. The stabilizing plate 116 is rotatably connected to the first rotating rod 109 and also rotatably connected to the second rotating rod 111.
[0031] In this embodiment, the stabilizing plate 116 increases the stability of the first rotating rod 109 and the second rotating rod 111, making the locking of the fixing component more stable and smooth.
[0032] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
