DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0024] It should be noted that when an element is referred to as being "connected" or "mounted" to another element, it can be directly connected or mounted to the other element, or indirectly connected or mounted to the other element through an intermediate element. In addition, the terms "upper", "lower", "left", "right", "inner", "outer" and similar expressions used herein are only for the purpose of illustration, and do not represent the only implementation.

[0025] As Figures 1-4As shown, a temperature sensing, window closing, positioning integrated hinge comprises a window closer 1, a temperature sensing damping positioning assembly 2 and a hinge assembly 3 for connecting a window sash and a window frame, the window closer 1 comprises a sleeve 11, a torsion spring 12 and a rotating shaft 13 arranged in the sleeve 11, the rotating shaft 13 is rotatably connected with the sleeve 11, two ends of the torsion spring 12 are connected with the sleeve 11 and the rotating shaft 13 respectively and the torsion spring 12 applies an elastic torsion force to the rotating shaft 13 as a closing force, an output end 131 of the rotating shaft 13 extends out of the sleeve 11 and is fixedly connected with one branch of the hinge assembly 3; the temperature sensing damping positioning assembly 2 comprises a friction piece 21 and a temperature sensing element 22 capable of exploding or melting under heat in a fire, the temperature sensing element 22 directly or indirectly presses the friction piece 21 to make the friction piece 21 abut against the rotating shaft 13; in a normal state, the friction force between the friction piece 21 and the rotating shaft 13 is greater than the closing force so that the closing force cannot drive the window sash to automatically close, and the rotating shaft 13 can rotate relative to the sleeve 11 under the action of an external force to overcome the resultant force of the friction force and the closing force; when the temperature sensing element 22 explodes or melts under heat, the pressure applied to the friction piece 21 can be released so that the closing force can drive the window sash to automatically close.

[0026] The temperature sensing, window closing, positioning integrated hinge provided by the application has the following advantages: during installation and use, the window sash is hingedly connected with the window frame through the hinge assembly 3, and the side wall of the sleeve 11 is fixedly connected with the window sash; in a normal use state, when a user manually pushes or pulls the window sash, the artificial force is greater than the resultant force of the friction force between the friction piece 21 and the rotating shaft 13 and the closing force of the window closer 1, so that the window sash can be normally rotated to open or close, and during the normal rotation, the torsion spring 12 of the window closer 1 is twisted, which can effectively prevent the torsion spring 12 from being locked for a long time and losing elasticity or even completely failing; when the user stops pushing or pulling the window sash after the window sash is pushed or pulled to any angle, the window sash is positioned due to the fact that the friction force between the friction piece 21 and the rotating shaft 13 is greater than the closing force of the window closer 1, and a friction sheet or other structure capable of achieving the positioning function does not need to be additionally arranged in the hinge or other parts; when a fire occurs, the temperature sensing element 22 melts or explodes when the ambient temperature exceeds the critical melting or exploding temperature, so that the pressure applied to the friction piece 21 is lost, the friction force between the friction piece 21 and the rotating shaft 13 is rapidly reduced or disappears, and the closing force of the window closer 1 can drive the window sash to automatically close.

[0027] Compared with the prior art, the temperature sensing, window closing, positioning integrated hinge provided by the application has the following advantages: the integrated design integrates four functions of temperature sensing, window closing, positioning and hinge into one, the structure is simple and compact, the number of parts is small, the design is ingenious, the production and manufacturing cost is low, the installation process is simple, the product is durable and not easy to be damaged, and the use and maintenance are convenient.

[0028] As a preferred embodiment, the temperature-sensing damping positioning assembly 2 further comprises a bracket 23 and an adjusting screw 24, the bracket 23 is fixedly connected to the sleeve 11, the adjusting screw 24 is threadedly connected to the bracket 23, one end of the temperature-sensing element 22 directly or indirectly abuts against the adjusting screw 24, and the other end of the temperature-sensing element 22 directly or indirectly abuts against the friction member 21, so that the temperature-sensing element 22 is pushed to move by rotating the adjusting screw 24, thereby adjusting the extrusion force of the temperature-sensing element 22 on the friction member 21, and further adjusting the friction force of the friction member 21 on the rotating shaft 13. The advantage of this design is that when the friction force of the friction member 21 on the rotating shaft 13 is too large, causing the user to manually open and close the window to be more difficult, the adjusting screw can be appropriately loosened to appropriately reduce the friction force (the adjusted friction force is still greater than the closing force), and the user can open and close the window more easily; when the friction force of the friction member 21 on the rotating shaft 13 is less than the closing force, causing the sash to be difficult to stop at any angle, the adjusting screw can be appropriately tightened to appropriately increase the friction force, and the adjustment is convenient.

[0029] As a preferred embodiment, the temperature-sensing damping positioning assembly 2 further comprises a transmission member 25, the temperature-sensing element 22 extrudes the friction member 21 through the transmission member 25, the temperature-sensing element 22 is a rod-shaped structure made of a fusible metal or temperature-sensing glass material, the adjusting screw 24, the temperature-sensing element 22, and the transmission member 25 are sequentially arranged in the same direction and parallel to the rotating shaft 13 and the sleeve 11, and the movement direction of the friction member 21 is perpendicular to the rotating shaft 13, the transmission member 25 and the friction member 21 are respectively provided with a first inclined surface 251 and a second inclined surface 211 that match each other, so that the transmission directions of the transmission member 25 and the friction member 21 are perpendicular to each other. The advantage of this design is that the adjusting screw 24, the temperature-sensing element 22, and the transmission member 25 are parallel to the sleeve 11, occupying less space and having a more compact structure, and at the same time, the movement of the transmission member 25 in the vertical direction (parallel to the sleeve 11) can be converted into the movement of the friction member 21 in the horizontal direction (perpendicular to the sleeve 11) through the cooperation of the first inclined surface 251 and the second inclined surface 211, so that the friction member 21 can be extruded vertically to realize a larger friction force, and the structure is simple, the manufacturing cost is low, the work is stable, and in addition, different displacement transmission ratios of the transmission member 25 and the friction member 21 can be realized by setting different inclination angles of the first inclined surface 251 and the second inclined surface 211.

[0030] As a preferred implementation, the bracket 23 and / or the sleeve 11 is provided with a first limiting structure and a second limiting structure for guiding the movement direction of the transmission member 25 and the friction member 21 respectively. The advantage of this design is that the movement direction of the transmission member 25 and the friction member 21 can be guided and limited, increasing the stability of the work. Preferably, the bracket 23 is provided with two vertical plates 231 perpendicular to the sleeve 11, one of the vertical plates 231 is threadedly connected with the adjusting screw 24, and the transmission member 25 passes through a first through hole in the other vertical plate 231 and is guided by the first through hole. The side wall of the sleeve 11 is provided with a second through hole, and the friction member 21 passes through the second through hole and is guided by the second through hole. The advantage of this design is that the first through hole serves as the first limiting structure and the second through hole serves as the second limiting structure, which is simple in structure.

[0031] As a preferred implementation, the transmission member 25 includes a front segment transmission member 252 and a rear segment transmission member 253 connected in series, wherein the rear segment transmission member 253 passes through the first through hole and abuts against the temperature sensing element 22, and one side of the front segment transmission member 252 is attached to the inner side wall of the bracket 23, and the other side is provided with the first inclined surface 251. The advantage of this design is that the transmission member 25 adopts a segmented design, the rear segment transmission member 253 can have a smaller cross-sectional size to pass through the first through hole for guidance, and the front segment transmission member 252 can have a larger cross-sectional size to tightly attach to the inner side wall of the bracket 23. Moreover, this design enables the first inclined surface 251 and the inner side wall of the bracket 23 to offset the pressure in the horizontal direction borne by the transmission member, thereby limiting the horizontal shaking of the front segment transmission member in the horizontal direction.

[0032] As a preferred implementation, the shaft 13 is coaxially arranged in the sleeve 11, and the outer diameter of the shaft 13 matches the inner diameter of the sleeve 11, so that the sleeve 11 can limit the radial direction of the shaft 13. The front end of the friction member 21 is provided with a concave arc-shaped friction head 212, the size of the second through hole matches the size of the friction head 212, and the friction head 212 of the friction member 21 passes through the second through hole and clamps the side of the shaft 13. The advantage of this design is that the contact area between the friction member 21 and the shaft 13 is larger, and the friction force is greater. At the same time, the shaft 13 cannot shake horizontally in the sleeve 11.

[0033] As a preferred implementation, the side of the shaft 13 is provided with a ring groove 134, and the side wall of the sleeve 11 is correspondingly provided with a matching screw hole and a limiting screw 111, and the front end of the limiting screw 111 is inserted into the ring groove 134 to limit the axial direction of the shaft 13. The advantage of this design is that the shaft 13 can only rotate in the sleeve 11 and cannot move axially, and the structure is simple.

[0034] As a preferred embodiment, the sash closer 1 further comprises a torsion adjusting assembly 14 arranged in the sleeve 11, the torsion adjusting assembly 14 comprising a first adjusting member 141, a second adjusting member 142, a driving structure (not shown in the drawings) for driving the first adjusting member 141 to rotate relative to the sleeve 11, and a locking screw 143 for locking the rotation of the first adjusting member 141, the first adjusting member 141 and the second adjusting member 142 being connected in one-way transmission by a mutually cooperating ratchet structure 144, the second adjusting member 142 being connected with one end of the torsion spring 12, and the other end of the torsion spring 12 being connected with the rotating shaft 13. The advantage of this design is that when the first adjusting member 141 is rotated in a forward direction, the second adjusting member 142 can be driven to rotate by the ratchet structure, thereby driving the torsion spring 12 to rotate and increasing the force storage of the torsion spring 12, i.e. increasing the closing force, while when the first adjusting member 141 is rotated in a reverse direction, the second adjusting member 142 will not rotate in the reverse direction due to the one-way locking effect of the ratchet structure, thereby maintaining the force storage of the torsion spring 12. This design facilitates the adjustment of the force storage of the torsion spring 12 in a narrow working environment where the first adjusting member 141 cannot be continuously rotated in the circumferential direction.

[0035] As a preferred embodiment, the hinge assembly 3 comprises a first branch chain 31, a second branch chain 32, a third branch chain 33, a sash connecting plate 34 and a frame connecting plate 35 which are hingedly connected together, wherein the sash connecting plate 34 is in an L-shaped structure, the side wall of the sleeve 11 is fixedly connected with the vertical side plate of the sash connecting plate 34, and the output end 131 of the rotating shaft 13 is fixedly connected with one end of the first branch chain 31, the key function of this fixed connection being that the output end 131 of the rotating shaft 13 and the first branch chain 31 cannot rotate relative to each other. In other embodiments, the hinge assembly 3 can also be selected from other hinge assemblies in the prior art.

[0036] The above description is merely preferred embodiments of the present application and a description of the principles of the technology used. It should be understood by those skilled in the art that the scope of the application disclosed in the present application is not limited to the technical solutions formed by the specific combinations of the technical features described above, and should also cover other technical solutions formed by any combinations of the technical features described above or their equivalent features without departing from the inventive concept.
