Parking top rod 507 is arranged on one end of parking shift block 503 towards movable parking block 501, and parking top rod 507 is abutted with movable parking block 501 to drive parking tooth 504 to engage with rack 2.

[0046] Among them, movable parking block 501 is rotatably connected on gear shaft 508, and gear shaft 508 is fixed in guide component 1. Parking tooth reset elastic member 502 is a spring, and parking tooth reset elastic member 502 is arranged on both sides of movable parking block 501 respectively, one end of parking tooth reset elastic member 502 is abutted on movable parking block 501, and the other end is abutted in guide component 1.

[0047] AsFigure 6 As shown, by pushing the stop dial 503 forward, the stop top rod 507 will abut against the movable stop block 501, the movable stop block 501 rotates and drives the stop gear teeth 504 to engage with the rack 2 to limit the movement of the rack 2. When the stop gear teeth 504 engage with the rack 2, the limiting step 505 on the stop dial 503 will be clamped in the stop limiting hole 506, thereby limiting the backward movement of the stop dial 503. When the stop dial 503 is pushed upward, the clamping of the stop limiting hole 506 on the limiting step 505 is released, thereby manually releasing the stop state.

[0048] In this embodiment, the rear part of the stop dial 503 is provided with a locking elastic member 513, one end of the locking elastic member 513 abuts against the side of the stop dial 503 away from the top bead hole 511, and the other end abuts against the guide part 1. The locking elastic member 513 can increase the stability of the stop dial 503 in the stop state.

[0049] In this embodiment, when an external force (such as human force or wind force) acts on the door leaf or the window leaf, and the external force is greater than the stop force of the stop mechanism 5, the stop mechanism 5 releases the stop state, and the window leaf or the door leaf can be closed, which is a way to release the above-mentioned stop state. Figure 4 and 5 As shown, the stop dial 503 is provided with a stop rod hole 509 at the end facing the movable stop block 501, which cooperates with the stop top rod 507. The stop rod hole 509 is provided with a stop shaft reset elastic member 510, one end of the stop shaft reset elastic member 510 abuts against the annular step formed on the outer wall of the stop top rod 507, and the other end abuts against the step formed on the inner wall of the stop rod hole 509; the stop dial 503 is provided with a stop pin for limiting the maximum extension length of the stop top rod 507, and the stop top rod 507 can only move within the range of the stop pin.

[0050] The stop dial 503 is provided with a top bead hole 511 on the side wall facing the stop limiting hole 506, the top bead hole 511 is in communication with the inner end of the stop rod hole 509, and a top bead 512 is arranged in the top bead hole 511, the top bead 512 abuts and cooperates with the inner end of the stop top rod 507, and the stop top rod 507 pushes the top bead 512 out of the top bead hole 511. The end of the stop top rod 507 abutting and cooperating with the top bead 512 is provided with an inclined surface, which facilitates the pushing of the top bead 512.

[0051] As shown in Figure 7As shown, under the action of external force on the door leaf or the window leaf, the swing arm 4 is driven to close, the gear 3 connected with the swing arm 4 drives the rack 2 to slide, the rack 2 drives the movable stop block 501 to rotate by extruding and abutting the stop teeth 504 in the sliding process, the movable stop block 501 pushes the stop rod 507 to move into the stop rod hole 509 (since the limiting step 505 on the stop block 503 is clamped in the stop limiting hole 506, the stop block 503 is in a static state), the inner end of the stop rod hole 509 pushes the top bead 512 out of the top bead hole 511, the top bead 512 is extruded on the inside of the guide component 1, and through the reaction force, the rear end of the stop block 503 is raised, when the rear end of the stop block 503 is raised, the limiting step 505 is separated from the stop limiting hole 506, and then the whole stop block 503 can move backward, that is, the stop mechanism 5 is released from the stop state, and the window leaf or the door leaf can be closed.

[0052] The energy storage padlock mechanism 6 has three modes when working: (1) the unlocking assembly 601 moves backward and abuts against the lock catch assembly 603, releasing the clamping and limiting of the lock catch assembly 603 itself and the temperature sensing limiting assembly 602, which is the state of the door and window having closing force; (2) the unlocking assembly 601 abuts against the lock catch assembly 603 and moves backward, starting the clamping and limiting of the lock catch assembly 603 itself and the temperature sensing limiting assembly 602, which is the state of the door and window having no closing force or the energy storage state; (3) based on the above-mentioned (2) state, the temperature sensing limiting assembly 602 senses fire and releases the clamping and limiting of the lock catch assembly 603 itself, which is the temperature sensing fireproof state of the door and window.

[0053] Specifically, as shown in Figure 8 and 9 The lock catch assembly 603 includes a lock block body 603-1, the lock block body 603-1 is slidingly arranged in the guide component 1, the lock block body 603-1 is provided with a main stop block 603-2 and a secondary stop block 603-3, both of which are rotationally connected in the lock block body 603-1; the main stop block 603-2 is provided with a hook groove 603-4 on the side close to the temperature sensing limiting assembly 602, the hook groove 603-4 faces away from the elastic energy storage element 604; the secondary stop block 603-3 is located on the side facing the hook groove 603-4, the lower end of the secondary stop block 603-3 abuts against the main stop block 603-2, and the secondary stop block 603-3 is provided with a stop block reset elastic element 603-5 on the side away from the main stop block 603-2, one end of the stop block reset elastic element 603-5 abuts against the lower part of the secondary stop block 603-3, and the other end abuts against the inner wall of the lock block body 603-1.

[0054] The unlocking assembly 601 comprises an unlocking top block 601-1 and an elastic buffer 601-3 arranged at the rear end of the rack 2, the elastic buffer 601-3 is in abutting fit with the lock block body 603-1, and the unlocking top block 601-1 is rotationally connected at the rear end of the rack 2 and is in abutting fit with the upper end of the secondary stop block 603-3.

[0055] As shown in Figure 10 the lower end of the secondary stop block 603-3 is abutted against the primary stop block 603-2 under the action of the stop block reset elastic element 603-5, the secondary stop block 603-3 limits the rotation of the primary stop block 603-2, and the hook groove 603-4 of the primary stop block 603-2 is hooked and connected on the temperature sensing limiting assembly 602, and the lock block body 603-1 in the lock catch assembly 603 is abutted against the elastic energy storage element 604, so that the elastic energy storage element 604 is in the energy storage state. In this state, the unlocking assembly 601 and the lock catch assembly 603 have a certain spacing, and within the spacing, the rack 2 can move freely under the action of the elastic energy storage element 604, that is, within a certain angle range, the door and window leaf is not subjected to the closing force (this is the door and window without closing force state or energy storage state).

[0056] As shown in Figure 11 when the opening angle of the door and window leaf exceeds the range value, the rack 2 will extrude the lock block body 603-1 through the elastic buffer 601-3, in this process, the elastic buffer 601-3 will be compressed, and when the elastic buffer 601-3 is compressed to the shortest state, the unlocking top block 601-1 extrudes and rotates the secondary stop block 603-3, when the lower end of the secondary stop block 603-3 loses the abutting limit of the primary stop block 603-2, the primary stop block 603-2 can rotate freely, at this time, the door and window leaf is released, the rack 2, the unlocking assembly 601 and the lock catch assembly 603 move forward as a whole under the action of the elastic energy storage element 604, and then the door and window leaf is subjected to the closing force (this is the door and window with closing force state).

[0057] In the process of moving forward with the lock block body 603-1, the hook groove 603-4 on the primary stop block 603-2 will be rotated by the temperature sensing limiting assembly 602, and then abut against the lower end of the secondary stop block 603-3, in the later closing process of the door and window leaf, the elastic buffer 601-3 gradually resets, and the unlocking top block 601-1 gradually loses the pressure on the upper end of the secondary stop block 603-3, however, at this time, the primary stop block 603-2 is abutted against the lock block body 603-1 on the side away from the hook groove 603-4, so that the secondary stop block 603-3 can keep the primary stop block 603-2 under the action of the stop block reset elastic element 603-5.

[0058] As shown in Figure 12As shown, when the opening angle of the door or window exceeds the range value, the rack 2 will press the lock block 603-1 and the elastic energy storage element 604 backward through the elastic buffer 601-3. When the lock block 603-1 moves to the position of the temperature sensing limiting assembly 602, the side wall of the hook groove 603-4 will be in contact with the temperature sensing limiting assembly 602. Under the action of the temperature sensing limiting assembly 602, the main stop block 603-2 is reset to realize the hooking and clamping of the hook groove 603-4 to the temperature sensing limiting assembly 602. At this time, the sub-stop block 603-3 is reset, and its lower end is limited to the rotation of the main stop block 603-2. After that, the door or window returns to the state as shown, that is, the door or window is not affected by the closing force. Figure 10 As shown, the door or window is not affected by the closing force.

[0059] It should be noted that after the lock is unlocked, as long as the opening angle of the door or window does not exceed the range value, the door or window will not be in the state as shown, that is, the door or window will be affected by the closing force within the set angle range. Figure 12 As shown, the door or window is not affected by the closing force.

[0060] In this embodiment, the unlocking assembly 601 further comprises an unlocking top block reset elastic element 601-2, one end of the unlocking top block reset elastic element 601-2 is abutted against the rack 2, and the other end is abutted against the unlocking top block 601-1.

[0061] As shown in Figure 8 and 10 As shown, the temperature sensing limiting assembly 602 comprises a hook groove stop block 602-1, which is rotatably connected in the guide component 1. The hook groove stop block 602-1 is in clamping and limiting cooperation with the hook groove 603-4. The hook groove stop block 602-1 is provided with a temperature sensing element 602-2 at the end away from the hook groove 603-4. The temperature sensing element 602-2 is abutted against the side wall of the hook groove stop block 602-1 away from the hook groove 603-4. The guide component 1 is provided with a stop block limiting hole at the position corresponding to the hook groove stop block 602-1. One side of the hook groove stop block 602-1 is abutted against the temperature sensing element 602-2, and the other side is abutted against the hole wall of the stop block limiting hole. The tail end of the temperature sensing element 602-2 is generally provided with a jackscrew for adjusting the pressing force of the temperature sensing element 602-2 to the hook groove stop block 602-1. The jackscrew can be installed in the guide component 1.

[0062] Based on the state as shown above Figure 10 As shown, the door or window is not affected by the closing force. Figure 13As shown, when the temperature sensing element 602-2 senses the occurrence of fire, it explodes by itself, releasing the limiting of the hook groove block 602-1, so that the hook groove block 602-1 can rotate freely and lose the limiting of the hook groove 603-4. Thereafter, the locking assembly 603 hits the elastic buffer 601-3 of the unlocking assembly 601 under the action of the elastic energy storage element 604, and then pushes the rack 2 to move forward, so that the door or window leaf is automatically closed under the action of the closing force.

[0063] It should be noted that even if the parking mechanism 5 is in the parking state, when the temperature sensing element 602-2 senses the occurrence of fire and explodes, the elastic energy storage element 604 releases the action on the rack 2, so that the parking assembly 5 can also be released from the parking state, and the window or door leaf can be closed.

[0064] In the embodiment, the locking block 603-1 is provided with an outward protruding limiting tongue 603-6 on the side facing the hook groove 603-4, and the limiting tongue 603-6 is in abutting cooperation with the hook groove block 602-1. The limiting tongue 603-6 limits the movement limit of the locking block 603-1 moving backward.

[0065] The above-described embodiments are only used to describe the preferred modes of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
