[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Embodiment 1

[0042] This embodiment provides a locking mechanism. Figure 1-6 , used to temperature-control lock the slider 20 in the temperature-controlled door and window closing device on the guide component 30, the locking mechanism 10 includes a temperature-controlled element 11, a positioning assembly 12 and a clamping component 13. Among them, the clamping component 13 includes a latch 131 and a limiter 132, the slider 20 is provided with a sliding slot corresponding to the latch 131, and the guide component 30 is provided with a holder, the latch 131 is slidably arranged in the sliding slot, and can be slid into the holder to complete the locking of the slider 20 and the guide component 30. Specifically, the clamping end of the latch 131 corresponding to the holder is smaller than the other end, and the size of the holder is adapted to the clamping end, thereby ensuring that the latch 131 will not fall out of the holder when the sliding slot slides. Preferably, the holder can be correspondingly arranged at one end of the sliding slot.

[0043] The main function of the limiting member 132 is to limit the sliding of the latch tongue 131 in the sliding slot, that is, to ensure that the latch tongue 131 is in a state of being engaged with the socket in normal working state, so as to achieve locking of the slider 20 and the guide member 30.

[0044] In terms of the temperature control element 11, its main function is to limit the position of the clamping component 13 on the slider 20 under normal working conditions so that it is in a locked state. When the temperature rises to the preset temperature, the temperature control element 11 melts or deforms, thereby releasing the locked state of the clamping component 13 to facilitate subsequent actions. Specifically, one end of the temperature control element 11 directly or indirectly abuts against the limiter 132, and the clamping tongue 131 is clamped on the holder through the limiter 132. At the other end, the temperature control element 11 abuts against the positioning component 12, and the positioning on the slider 20 is achieved through the positioning component 12. Specifically, the clamping tongue 131 extends from the sliding slot under the force of the limiter 132 and is clamped with the holder, thereby achieving the locking of the slider.

[0045] When the temperature-controlled door and window closing device is working normally, the locking mechanism 10 completes the locking of the slider 20 and the guide component 30 through the cooperation of the temperature-controlled element 11, the positioning assembly 12 and the clamping component 13. When a fire occurs, after the temperature reaches the preset value, the temperature-controlled element 11 melts or deforms, thereby releasing the limit on the clamping component 13. At this time, the latch tongue 131 can be retracted into the sliding slot under the action of external force, releasing the clamping connection with the clamping seat, and then releasing the lock of the slider 20 and the guide component 30, so that the temperature-controlled door and window closing device can perform subsequent actions.

[0046] The advantage is that the locking mechanism 10 of this embodiment has a simple and effective structure, is firmly and reliably connected, and is flexible to open and close. After a fire occurs, the slider 20 and the guide component 30 can be quickly unlocked to ensure that the window can be closed quickly afterwards to prevent the fire from spreading.

[0047] As a preferred embodiment of this embodiment, refer to Figure 1-6 The guide component 30 is provided with an assembly groove corresponding to the size of the temperature control element 11 at the corresponding position of the temperature control element 11, wherein the corresponding position of the temperature control element 11 refers to the position of the temperature control element 11 when the slider 20 and the guide component 30 are in the locked state. And corresponding to the size of the temperature control element 11 means that the size of the assembly groove is the same as or slightly larger than the size of the temperature control element 11. Of course, in some implementation cases, the size of the assembly groove can ensure that the temperature control element 11 can be smoothly installed in the preset position in the slider 30 through the assembly groove.

[0048] In terms of positioning assembly 12, preferably, refer to Figure 1-6 The positioning assembly 12 includes a threaded member 121 , and a screw hole corresponding to the threaded member 121 is opened on the slider 20 . The threaded member 121 directly or indirectly adjusts and positions the temperature control element 11 through the screw hole.

[0049] Regarding the connection between the stopper 132 and the latch tongue 131, preferably, refer to Figure 1-6The limiting member 132 is slidably assembled in the slider 20, and one end of the limiting member 132 can slide into the sliding slot, thereby limiting the position of the latch tongue 131 in the sliding slot. On the contact surface between the limiting member 132 and the latch tongue 131, the limiting member 132 is provided with an inclined surface at the contact surface, and the latch tongue 131 is provided with an arc surface at the contact surface. The limiting member 132 and the latch tongue 131 are connected by the matching limiting connection of the inclined surface and the arc surface, ensuring that the latch tongue 131 can be smoothly received into the sliding slot when the lock is released.

[0050] In this embodiment, the temperature control element 11 is a temperature-sensitive glass ball or a fusible alloy. When a fire occurs, the temperature-sensitive glass ball breaks or the fusible alloy melts, thereby releasing the lock of the locking mechanism 10 and performing the subsequent window closing action.

[0051] As a preferred embodiment of this embodiment, refer to Figure 1-3 The temperature control element 11 is provided with a first pad 14 and a second pad 15 at both ends. Specifically, the temperature control element 11 is abutted against the limiting member 132 through the first pad 14, and the other end is abutted against the positioning assembly 12 through the second pad 15. The positioning assembly 12 is positioned to complete the close abutment of the limiting member 132, thereby completing the limiting of the latch 131. Further preferably, the positioning assembly 12 specifically includes a push block 122 and a threaded member 121. The push block 122 and the second pad 15 are relatively provided with corresponding inclined surfaces, and the two are abutted through the inclined surfaces. The threaded member 121 is threadedly connected in the screw hole of the slider 20, and the bottom is vertically extruded and connected with the push block 122. The second pad 15 is pushed toward the temperature control element 11 through the threaded member 121 and the push block 122, thereby completing the positioning of the temperature control element 11. More specifically, in this solution, the temperature control element 11 is preferably a temperature control glass ball.

[0052] As a preferred embodiment of this embodiment, refer to Figure 1-3 The slider 20 is provided with a protrusion at the limit member 132, and the limit member 132 is provided with a corresponding clamping portion. Specifically, the protrusion is arranged close to the horizontal slide groove. Through the cooperation of the protrusion and the clamping portion, the horizontal sliding of the limit member 132 is limited, thereby achieving the purpose of limiting the length of the limit member 132 entering the sliding clamping groove.

[0053] Embodiment 2

[0054] This embodiment is similar to the first embodiment, except for the coordination between the temperature control element 11 and the limiting member 132 .

[0055] For details, please refer to Figure 4-6In this embodiment, a transmission lever 16 is further provided between the temperature control element 11 and the limiter 132, and the transmission lever 16 is provided with two transmission ends. A bearing that cooperates with the transmission lever 16 is provided on the slider 20, and the transmission lever 16 is installed on the slider 20 through the bearing, and the two transmission ends are respectively in contact with the temperature control element 11 and the limiter 132, thereby realizing the transmission and limiting between the temperature control element 11 and the limiter 132. More specifically, the transmission lever 16 is a special-shaped transmission lever 16.

[0056] Embodiment 3

[0057] This embodiment provides a temperature sensing door and window closing device, see Figure 7-12 , including a guide component 30, a power storage assembly 40, a rack component 50, a connecting rod 60, a slider 20 and the locking mechanism 10 described in the first or second embodiment. The rack component 50 can reciprocate along the guide component 30, a gear structure 61 is provided at one end of the connecting rod 60, and a tooth groove corresponding to the gear structure 61 is provided on the rack component 50. The connecting rod 60 is connected to the rack component 50 through the gear structure 61 and the tooth groove of the rack component 50.

[0058] The slider 20 is connected to the guide component 30 by temperature control locking through the locking mechanism 10, and one end of the slider 20 is connected to the guide component 30 through the power storage component 40. In normal operation, the slider 20 and the guide component 30 are in a locked state, the power storage component 40 cannot be released, and the connecting rod 60 is opened and closed normally through the gear structure 61. When a fire occurs, the locking mechanism 10 is unlocked, and the power storage component 40 releases the slider 20, thereby driving the rack component 50 to reset along the guide component 30, and then driving the connecting rod 60 to automatically close through the gear structure 61.

[0059] In addition, a damping component is provided at one end of the slider 20 close to the rack component 50, and the damping component is connected to the rack component. In this embodiment, the damping component includes a strip-shaped body arranged along the length direction of the guide component, and the surface of the strip-shaped body is rough, and the rack component is closely in contact with the strip-shaped body. Due to the rough surface of the strip-shaped body, the rack component 50 will encounter greater resistance when moving relative to the surface of the strip-shaped body, thereby achieving the effect of maintaining the window opening angle. Please refer to Figure 8 and Fig. 9 , which illustrates that the rack component 50 is in contact with the strip body by forming a clamping mechanism through an auxiliary structure.

[0060] The advantage of this structure is that, under normal circumstances, the device locks the slider 20 through the locking mechanism 10, and the connecting rod 60 can be opened and closed normally. After a fire occurs, the locking structure is quickly unlocked through the temperature control element 11, and the driving slider 20 is released through the power storage component 40 to drive the rack component 50 to reset, and finally the connecting rod 60 is closed. It has a simple structure, firm and reliable clamping, flexible opening and closing, can effectively and quickly close the window sash, prevent the spread of fire, ensure the fire resistance of the window, and improve the safety and market competitiveness of the window.
