Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to better understand the advantages and features of the present invention, and to define the scope of the present invention more clearly.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "head", "tail", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, are not to be construed as limiting the present invention.

The first embodiment is as follows:

the embodiment of the utility model provides a as shown in fig. 1 and fig. 2, fig. 1 has illustrated the structural principle explosion diagram that is used for the temperature sensing actuating mechanism 20 of door and window closer, and the actuating mechanism 20 that this embodiment is disclosed is used for providing drive power for door and window automatic closure under the condition that the conflagration takes place, and its overall structure is simple, small and safe and reliable. Can be arranged on aluminum alloy doors and windows, and can be directly arranged on window sashes or window frames together with plastic-steel doors and windows.

Referring to fig. 1 and 2, the temperature-sensitive driving mechanism 20 for a door/window closer includes a sliding mechanism 10, a driving mechanism 20, and a locking mechanism 30.

The sliding mechanism 10 is used to drive the window to close, and the principle of the sliding mechanism is usually to cooperate with a pull rod, so as to drive one end of the pull rod to move during the sliding process of the sliding mechanism 10, thereby realizing the rotation of the window.

The driving mechanism 20 is used to provide a driving force to the sliding mechanism 10, which is used to force the sliding mechanism 10 to slide on a straight line in an emergency state. For example, when the door closer is mounted to the frame, the driving mechanism 20 provides a unidirectional linear pushing force to the sliding mechanism 10.

And a locking mechanism 30 for normally preventing the slide mechanism 10 from being freely driven by the driving mechanism 20 and constantly putting the driving mechanism 20 in a potential accumulation state. Only when the door or window is in an emergency state, the locking mechanism 30 cancels the restriction of the driving mechanism 20, so that the potential energy is released and converted into kinetic energy, thereby pushing the sliding mechanism 10 to move, and the door or window is closed.

Specifically, the sliding mechanism 10 is a generally flat main body, and includes a first sliding slot 11 and a limiting member 12. The first sliding slot 11 and the limiting member 12 cooperate with each other to lock the sliding mechanism 10. The limiting member 12 can move along the first sliding slot 11 in the sliding slot, but since the sliding mechanism 10 itself needs to slide, the limiting member 12 has no displacement or a small displacement in the moving direction of the sliding mechanism 10.

Preferably, the first sliding chute 11 is disposed along the moving direction of the sliding mechanism 10, and the moving direction of the limiting member 12 is different from the moving direction of the sliding mechanism 10. Further preferably, the two directions may be in a perpendicular relationship to each other.

In order to lock the sliding mechanism 10, a bayonet 13 is opened on a side wall of the first sliding chute 11, and the bayonet 13 is used for receiving the limiting member 12. During use, the limiting member 12 will fall into the bayonet 13. Due to the action of the bayonet 13, the sliding mechanism 10 is clamped and cannot slide freely, and the sliding mechanism 10 can move only when the limiting piece 12 enters the first sliding chute 11 from the bayonet 13.

Therefore, the main purpose of the locking mechanism 30 is to prevent the stopper 12 from falling into the first chute 11. Specifically, in the present embodiment, the locking mechanism 30 abuts against the limiting member 12 to limit the limiting member 12 from falling into the first sliding chute 11. The locking mechanism 30 is provided with a temperature control element 31 and a pushing piece 32, the temperature control element 31 forces the pushing piece 32 to abut against the limiting piece 12, when the temperature reaches a specific value, the pushing piece 32 deforms or breaks, the limiting piece 12 contacts and limits, and enters the first sliding groove 11, so that the sliding mechanism 10 moves and slides without being influenced by the limiting piece 12. Preferably, the critical temperature of the locking mechanism 30 may be 60 ℃ to 65 ℃.

The temperature-sensitive driving mechanism 20 of the door and window closer can also be provided with a housing 40 for accommodating all the components, wherein the housing 40 is an elongated U-shaped groove body or a tubular structure, and further can be but is not limited to a square tubular structure. The limiting member 12 can realize a movement perpendicular to the sliding direction of the sliding mechanism 10 under the cooperation of the housing 40, and at this time, the limiting member 12 may be a limiting column, or may have another shape. Specifically, the housing 40 is provided with a second sliding slot, which is perpendicular to the first sliding slot 11, and the limiting member 12 is movably disposed in the second sliding slot. While the housing 40 also serves to house the drive mechanism 20.

In addition, in the aspect of the locking mechanism 30, one end of the temperature control element 31 is fixedly connected with the housing 40, and the other end of the temperature control element is connected with the pushing piece 32 in a limiting manner, so that the pushing piece 32 is positioned on the housing 40, and the locking mechanism 30 limits the limiting piece 12 on the bayonet 13 through the clamping connection between the pushing piece 32 and the limiting piece 12.

In this embodiment, referring to fig. 1 and fig. 2, the pushing element 32 includes a card 321 and a latch 322, the card 321 is movably connected to the housing 40, and the card 321 can be connected to the housing 40 by a connecting portion and positioned by the temperature control element 31. For example, the card 321 is provided with a protruding clamping portion, the card 321 is clamped on the housing 40 through the clamping portion, and the card 321 is provided with a groove, and is abutted against the temperature control element 31 through the groove. One end of the latch 322 abuts against the card 321, and the other end is latched with the limiting member 12, so that the limiting member 12 is limited in the bayonet 13 and cannot be disengaged. The end surfaces of the fixture block 322 and the limiting member 12 abutting against each other are inclined surfaces to form a wedge-shaped structure, and the thrust in the moving direction of the sliding mechanism 10 is converted into a thrust perpendicular to the moving direction of the limiting member 12, so that the limiting member 12 is limited in the bayonet 13.

In this embodiment, the temperature control element 31 specifically includes a bracket 311, a buffer spring 312 and a temperature sensing unit 313, one end of the temperature sensing unit 313 abuts against the bracket 311 through the buffer spring 312, and the other end abuts against the pushing element 32 for limiting. The main function of the buffer spring 312 is to finely adjust the position of the temperature sensing unit 313 to ensure the engagement with the pushing member 32. It is further preferable that the temperature sensing unit 313 is disposed outside the housing 40 to ensure convenience in replacement for subsequent use.

In this embodiment, the support 311 includes an abutting end of the main body, and the support 311 is connected to the temperature sensing unit 313 through the abutting end and can be fixedly disposed on the outer surface of the housing 40 through the main body. For example, the bracket 311 is fixed to one side of the housing 40 by screws, or is wound around an outer surface of an end portion of the housing 40.

In the aspect of the driving mechanism 20, it may be a linear elastic mechanism, one end of which is fixed, and the other end of which is connected to the sliding mechanism, and the linear elastic mechanism is normally in an accumulated state. For example, the driving mechanism 20 may be a compression spring or a tension spring. Conventionally, the compression spring is compressed and the tension spring is extended. Once the locking mechanism 30 is contact locked, the force of the driving mechanism 20 is momentarily released, providing a driving force.

In addition, when the temperature sensing unit 313 is made of fusible metal, the fusible metal is easy to deform at normal temperature due to a low melting point, so that the locking effect of the pushing piece 32 is disabled.

Preferably, the temperature sensing unit 313 may be, but is not limited to, a fusible metal or a temperature sensing glass ball.

In this embodiment, the bayonet 13 is disposed at an end of the first sliding slot 11, and a depth of the bayonet 13 is smaller than or equal to a radius of the limiting member 12. The beneficial effect of this mode of setting lies in, because the locating part 12 radius is greater than bayonet 13 degree of depth, locating part 12 then can not blocked by bayonet 13 completely, needs external force cooperation just can realize fixedly.

Example two:

as a parallel scheme of the first embodiment, the present embodiment is different from the first embodiment in that: the locking mechanism 30 in this embodiment is provided.

Referring to fig. 3, in the present embodiment, the locking mechanism 30 also includes a temperature control element 31 and a pushing element 32, but the pushing element 32 is provided with a positioning slot, the positioning slot is provided with a slot opening having the same size as the limiting element 12, and is provided with a slot seat having a size larger than that of the limiting element 12. The pushing piece 32 is sleeved on the limiting piece 12 through a positioning groove, and the limiting piece 12 is locked in the bayonet 13 through a notch.

When an emergency occurs, the temperature sensing unit 313 is deformed or broken by heat, the temperature control element 31 releases the locking between the pushing member 32 and the limiting member 12, the limiting member 12 enters the slot seat under the pushing of the driving mechanism 20 and slides into the first sliding slot 11, the locking of the locking mechanism 30 on the sliding mechanism 10 is released, and the sliding mechanism 10 can slide.

Example three:

Referring to fig. 4, in the present embodiment, the locking mechanism 30 includes a temperature sensing unit 313 and a pushing member 32. The pushing member 32 is used for pushing the limiting member 12 to keep fixed in the bayonet 13, and is usually in abutting relation with the limiting member 12. The temperature sensing unit 313 is used for providing a locking and supporting function for the position of the pushing member 32 so that the pushing member 32 can keep pushing the limiting member 12 at any time. The temperature sensing unit 313 has one end fixed to the housing 40 and the other end abutting against the pusher 32. Specifically, the end surfaces of the pushing member 32 and the limiting member 12 abutting against each other are inclined surfaces to form a wedge-shaped structure, and the thrust in the moving direction of the sliding mechanism 10 is converted into the thrust perpendicular to the moving direction of the limiting member 12, so that the limiting member 12 is limited in the bayonet 13.

It is understood that different embodiments among the components in the above embodiments can be combined and implemented, and the embodiments are only for illustrating the implementation of specific structures and are not limited to the implementation of the embodiments.
