DETAILED DESCRIPTION

[0034] 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. Example

[0035] This embodiment provides a temperature-controlled window closing device. Figure 1-8 , including a mounting seat 1, a connecting rod 3, a temperature control element 4 and an impact assembly 5; wherein, a clamping mechanism 2 is provided on the mounting seat 1, and the connecting rod 3 includes a connecting end and a clamping end, and the connecting rod 3 is rotatably mounted on the mounting seat 1 through the clamping end. Specifically, the clamping end of the connecting rod 3 is provided with a gear tooth groove 31 and a protrusion 32 in sequence along the rotation direction of the connecting rod 3 to be opened, and the clamping mechanism 2 completes the one-way locking of the connecting rod 3 after opening by clamping with the gear tooth groove 31, and the protrusion 32 of the clamping end is used to unlock the locking of the connecting rod 3 by the clamping mechanism 2 and reset the clamping mechanism 2 after unlocking. The one-way locking of the connecting rod 3 by the clamping mechanism 2 means that when the connecting rod 3 rotates in the opening direction and rotates to a certain angle, the clamping mechanism 2 is engaged and locked with the gear tooth groove 31 corresponding to the angle, and after locking, the connecting rod 3 can only rotate in the opening direction, and cannot directly rotate in the closing direction. It is worth noting that after the connecting rod 3 and the locking mechanism 2 are one-way locked, they continue to rotate in the opening direction, and the locking mechanism 2 is dislocated by the protrusion 32 to release the lock of the two, and then the connecting rod 3 is closed. At the same time, after the connecting rod 3 is closed, the protrusion 32 drives the locking mechanism 2 to be reset to the locked state.

[0036] In addition, the impact assembly 5 includes an elastic member 51 and an impact member 52, one end of the elastic member 51 is an active compression end, the impact member 52 is connected to the active compression end of the elastic member 51, and the impact member 52 is limitedly connected to the temperature control element 4. Specifically, when the active compression end of the elastic member 51 is released, the impact member 52 can be driven to move in the opposite direction of the connection with the elastic member 51. In this embodiment, the elastic member 51 is a power spring. The temperature control element 4 completes the limit between the impact member 52 according to the temperature control, and when limiting, the elastic member 51 is continuously kept in a compressed state.

[0037] At the same time, the connecting rod 3 and the clamping mechanism 2 are both provided with impact parts 33 and 223 extending along the impact path of the impact member 52. When a fire occurs, the temperature rises, the temperature control element 4 contacts the limit of the impact member 52, and the elastic member 51 drives the impact member 52 to hit the impact part 233 of the clamping mechanism 2 and the impact part 33 of the connecting rod 3 in turn, so that the clamping mechanism 2 and the connecting rod 3 rotate in the unlocking rotation direction and the closing rotation direction respectively, thereby releasing the lock of the clamping mechanism 2 and the connecting rod 3, and driving the connecting rod 3 to complete the closing, thereby driving the window to close to the closed state to prevent the fire from spreading.

[0038] In some embodiments, see Figure 2-6 The clamping mechanism 2 includes a positioning assembly 21 and a buckle 22. Specifically, the positioning assembly 21 includes a fixed end and a rotating end. The buckle 22 is rotatably mounted on the mounting seat 1. One end is connected to the rotating end of the positioning assembly 21. The locking state and the unlocking state are maintained by the positioning assembly 21. The other end is provided with a locking convex tooth 221 and a reset convex tooth 222 on both sides of the position corresponding to the protrusion 32. The locking convex tooth 221 can be engaged with the gear tooth groove 31 of the connecting rod 3, thereby realizing a one-way locking between the buckle 22 and the connecting rod 3. In addition, the protrusion 32 of the connecting rod 3 can be rotated on the mounting seat 1 to toggle the locking convex tooth 221 and the reset convex tooth 222, thereby completing the switching of the locking state and the unlocking state of the buckle 22. Specifically, the protrusion 32 of the connecting rod 3 rotates in the opening direction of the connecting rod 3, thereby shifting the locking protrusion 221, shifting the buckle 22 to the unlocked state, releasing the engagement between the locking protrusion 221 and the gear tooth groove 31, and enabling the connecting rod 3 to be closed. In the unlocked state, the reset protrusion 222 of the buckle 22 is located at the closing path of the protrusion 32. When the connecting rod 3 is close to being completely closed, the protrusion 32 shifts the reset protrusion 222 of the buckle 22, thereby driving the buckle 22 to reset, and enter the locked state through the positioning assembly 21, that is, the clamping mechanism 2 returns to the initial position when the connecting rod 3 is closed.

[0039] In some embodiments, see Figure 2-6The positioning assembly 21 includes a positioning spring 211 and a spring mounting piece 212. One end of the spring mounting piece 212 is rotatably connected to the buckle 22 near the edge of the positioning assembly 21. One end of the positioning spring 211 is fixedly mounted on the mounting seat 1 and sleeved and connected to the other end of the spring mounting piece 212. Specifically, the positioning spring 211 is in a compressed state on the positioning assembly 21, and gives elastic force to the buckle 22 at all times. The principle of the positioning assembly 21 maintaining the locked state and unlocked state of the buckle 22 is that when the rotation axis of the spring mounting piece 212 on the buckle 22 is in a continuous position between the rotation axis of the buckle 22 on the mounting seat 1 and the mounting point of the positioning spring 211 on the mounting seat 1, the buckle 22 is balanced in force and remains stationary. When the buckle 22 rotates in the locking direction, that is, the rotation axis on the mounting seat 1 is located on the side of the above-mentioned connecting line toward the buckle locking, the positioning spring 211 exerts a force on the buckle 22 to push the locking protrusion 221 and the gear tooth groove 31 to engage with each other, thereby keeping the buckle 22 in the locked state. When the buckle 22 rotates in the unlocking direction, that is, the rotation axis on the mounting seat 1 is located on the other side of the above-mentioned connecting line, the positioning spring 211 exerts a force on the buckle 22 to force the buckle 22 away from the mutually locked position of the connecting rod 3, thereby keeping the buckle 22 in the unlocking state.

[0040] In some embodiments, see Figure 7-8 , an air avoidance groove is provided on one side of the impact member 52. After a fire occurs, that is, when the connecting rod 3 is hit and closed by the impact member 52, the connecting rod 3 can be opened and closed normally through the air avoidance groove of the impact member 52. In addition, the impact member 52 includes an inner plate 521 and an outer plate 522. The outer plate 522 is fixedly connected to the inner plate 521. The air avoidance groove is provided on the inner plate 521. The outer plate 522 is provided with a positioning groove corresponding to the limiting part on the temperature control element 4. The outer plate 522 is engaged with the limiting part of the temperature control element 4 through the positioning groove to ensure that the impact member 52 can be firmly positioned when no fire occurs, prevent misstarting, and ensure its reliability in a normal state. More specifically, the connection between the inner plate 521 and the outer plate 522 is hinged.

[0041] In some embodiments, see Figure 2 The temperature control element 4 includes a bracket 41, a top screw 42 and a temperature sensing element 43. The bracket 41 is fixedly arranged on the mounting base 1, and the temperature sensing element 43 is adjustably arranged on the bracket 41 through the top screw 42. The impact piece 52 can be directly or indirectly limited by the temperature sensing element 43. Under normal circumstances, the temperature sensing element 43 directly or indirectly limits the impact piece 52 to ensure that the elastic piece 51 is in a compressed state. When a fire occurs, the temperature sensing element 43 encounters high temperature and melts, and contacts the limit of the impact piece 52, thereby releasing the impact piece 52. Under the push of the elastic piece 51, the impact piece 52 hits the buckle 22 and the connecting rod 3 in turn, thereby reaching the window closing state.

[0042] In some embodiments, see Figure 2-8 The temperature control element 4 also includes a limiting piece 44, and the temperature sensing element 43 limits the impact member 52 through the limiting piece 44. The limiting piece 44 is provided with an arc surface at the connection with the impact member 52, and the air avoidance groove of the impact member 52 is provided with an inclined surface that cooperates with the arc surface of the limiting piece 44. The impact member 52 is actively connected with the arc surface of the limiting piece 44 through the inclined surface, and the other side of the limiting piece 44 is connected with the temperature sensing element 43, and is limited by the temperature sensing element 43 to ensure that the limiting piece 44 cannot move under normal conditions, thereby making the elastic member 51 in a compressed state.

[0043] Preferably, Figure 1-8 As shown, the temperature sensing element is a fusible alloy, and a slot matching the fusible alloy is provided on the limit plate; the fusible alloy clamping end is inserted into the limit plate and the slot to limit the limit plate. When the fusible alloy melts at high temperature, the limit plate 44 is released, and the impact member 52, driven by the elastic member 51, pushes the limit plate 44 along the inclined surface, thereby forming a release and completing the closing of the connecting rod 3.

[0044] Preferably, Fig. 9 As shown, a card is also arranged between the temperature sensing element and the limiting plate, the clamping end of the card is clamped with the limiting plate, and a clamping seat adapted to the temperature sensing element is protruding from the card. The temperature sensing element is inserted into the clamping seat to lock the card, and then the limiting plate is limited, thereby achieving the above-mentioned limiting effect on the impact member.

[0045] Further preferably, the card and the limit plate are both rotatably mounted on the mounting seat via a rotation axis, and the limit and the release of the limit are achieved by rotation. Specifically, in order to achieve a better clamping effect, the intersection angle of the two straight lines formed by the rotation axis of the card and the limit plate and the clamping points of the two is 84 degrees. At the same time, in the embodiment, the temperature sensing element is a temperature sensitive glass ball.

[0046] In some embodiments, see Figure 1 The temperature-controlled window closing device also includes a square tube 6, the other end of the elastic member 51 is fixedly connected to the end of the square tube 6, and the impact member 52 is slidably installed in the square tube 6. When the impact member 52 is released, it can move to the other end of the square tube 6 through the elastic member 51 and hit the buckle 22 and the connecting rod 3 to complete the closing of the connecting rod 3.

[0047] In addition, a slider 7 is provided at the connecting end of the connecting rod 3, and the connecting rod 3 can be connected to the slot body of the window through the slider 7, and the opening and closing of the window is completed by the reciprocating movement of the slider 7 in the slot body.

[0048] In some embodiments, see Figure 1-8, at least one gear tooth groove is provided. Preferably, the gear tooth groove 31 of this embodiment is provided with one or two gear tooth grooves. Correspondingly, when one gear tooth groove 31 is provided, the window closing device has a closed state and an open state. Figure 3-4 When there are two gear tooth grooves 31, the window closing device has a closed state, a first gear open state and a second gear open state.

[0049] For a better operating experience, please refer to Figure 1-8 , the assembly process of the device is provided. Specifically, firstly, the mounting seat 1 and the gasket are clamped into the clamping interfaces on both sides of the square tube 6, and the mounting seat 1, the gasket and the square tube 6 are fixed with screws. The connecting rod 3 and the buckle 22 are installed on one side of the mounting seat 1, and the bracket 41 and the limiting plate 44 are installed on the other side, and they are fixed with rivets and screws respectively; the spring mounting plate 212 and the positioning spring 211 are installed on the buckle 22, and they are fixed on the buckle 22 and the bracket 41 with screws respectively; then the inner plate 521 and the outer plate 522 are combined with screws Together, install them into the square tube 6, and use the inclined surface of the impact piece 52 to be tangent to the arc surface of the limiting plate. After the two inclined surfaces are tangent, install the temperature sensing element 43 at the notch of the limiting plate 44, and fix the temperature sensing element 43 on the bracket 41 with the top screw 42. If the two inclined surfaces are not tangent tightly enough, the temperature sensing element 43 can be controlled by adjusting the top screw 42 to make the two inclined surfaces fit together; finally, install the elastic member 51, that is, the spring, into the square tube 6 and press it against the tail end of the impact piece 52, compress the spring with a compression tool, and fix it with screws after compression; fix the slider 7 to the end of the connecting rod 3 with rivets.

[0050] The advantage of the temperature-controlled window closing device of this embodiment is that, under normal circumstances, the device clamps the clamping part of the connecting rod 3 through the clamping mechanism 2 to complete the multi-stage locking of the connecting rod 3. When closing, the clamping mechanism 2 is unlocked and reset through the protruding part 32. The device has a simple structure, firm and reliable clamping, and flexible opening and closing. In the event of a fire, the temperature sensing element 43 melts or breaks, the limit plate 44 and the impact member 52 release the limit so that the impact member 52 is in a released state, and the elastic member 51 drives the buckle 22 and the connecting rod 3 to release the lock of the buckle 22 and close the connecting rod 3, effectively and quickly closing the window sash to prevent the spread of fire. When a fire occurs in this structure, no matter what state the connecting rod 3 is in, it can ensure its rapid closure, ensure the fireproof performance of the window, and improve the safety and market competitiveness of the window.

[0051] This embodiment also provides a temperature-controlled closing window, including the temperature-controlled window closing device described above. Specifically, the main body of the temperature-controlled window closing device is installed on the window frame of the window body, and the connecting rod 3 and the slider 7 are installed on the window sash.
