Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only, e.g., first spring, second spring in the present embodiment, and are not to be construed as indicating or implying relative importance.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
This embodiment describes a window closer for fire window, as shown in fig. 1, which may generally include a movement 1, a guide rail 2 and a rocker 3, where the movement 1 is usually fixed on a window, the guide rail 2 is fixed on a wall, one end of the rocker 3 is connected to the movement 1, the other end is fixedly connected to an adjustable positioning device 4, and the positioning device 4 is assembled in the guide rail 2 and can reciprocate along the guide rail 2, where a distance between two sides of the positioning device 4 contacting the guide rail 2 is adjustable.
That is, adjusting the distance between the two sides of the positioning device 4 contacting the guide rail 2 can adjust the expansion degree of the positioning device 4 in the guide rail 2, so that the matching between the positioning device 4 and the guide rail 2 can be switched between sliding fit and interference fit, thus not only can the conventional window closing function between the positioning device 4 and the guide rail 2 under sliding fit be realized, but also the fixed point stopping function between the positioning device 4 and the guide rail 2 under interference fit can be realized, and the fixed point stopping is at any position, but also the stopping position at a specific position or angle, besides, the adjustment of the matching fastening degree between the positioning device 4 and the guide rail 2 can also realize the adjustment of the required force when the window is opened and closed by a user, and the abundant adjustable function can definitely better meet the use requirement of the user.
In this embodiment, specifically, as shown in fig. 2, the temperature-sensitive release device comprises a shell, and an adjusting block 47, a wedge block 45, a temperature-sensitive release element 42 and a set screw 41 which are encapsulated in the shell, wherein the set screw 41, the temperature-sensitive release element 42, the wedge block 45 and the adjusting block 47 are sequentially arranged from left to right, two fixing surfaces which are oppositely arranged are arranged in the adjusting block 47, the outer sides of the fixing surfaces are contacted with the side surface of the guide rail 2, a wedge-shaped cavity which can be inserted into the wedge block 45 is formed between the two fixing surfaces of the adjusting block 47, one end of the temperature-sensitive release element 42 is connected with the wedge block 45, the other end of the temperature-sensitive release element 42 is connected with the set screw 41, and the set screw 41 is arranged at the rear end of the shell and used for pushing the wedge block 45, wherein the wedge block 45 is forced to push the two fixing surfaces of the adjusting block 47, and the two fixing surfaces and the side surface of the guide rail 2 form interference fit.
That is, the fixed point stopping function is realized by the friction force between the outer side of the fixing surface and the guide rail 2, and the deeper the insertion depth of the wedge-shaped block 45 is, the larger the friction force between the fixing surface and the guide rail 2 is, correspondingly, the larger the external force is required when the window is opened or closed, for example, when the friction force is larger than the force of the rotation torque of the rocker arm, the window closer cannot close the window, and the window can also stop at the position where the last person releases the hand, so that the stopping at any point is realized.
When the window closer is under the fixed-point stopping function, if a fire disaster occurs, the window closer can rapidly complete the window closing action by melting or blasting the temperature sensing release element 42 (in the embodiment, the temperature sensing glass ball can be temperature sensing metal of course), so that one end of the wedge block 45 is not stressed any more, as shown in fig. 3, the wedge block 45 is withdrawn from the wedge cavity, the gap between the two fixing surfaces is immediately reduced, the friction between the fixing surfaces and the side surface of the guide rail 2 is reduced, the matching between the positioning device 4 and the guide rail 2 is rapidly switched to a sliding matching state, the window closer can rapidly complete the window closing action, the rapid conversion from the fixed-point stopping to the normal window closing is realized, and the fire disaster spreading can be limited after the window is closed, so that the safety performance of the window closer is effectively improved.
In order to ensure a quicker and more reliable withdrawal of the wedge-shaped block 45 from the wedge-shaped cavity of the adjusting block 47, a first spring 46 is arranged in the wedge-shaped cavity along the length direction of the guide rail 2, one end of the first spring 46 is fixedly connected to the adjusting block 47, the other end is fixedly connected to one side of the wedge-shaped block 45, and the other side of the wedge-shaped block 45 opposite to the side fixedly connected with the spring is connected to one end of the temperature-sensitive release element 42.
It will be appreciated that under normal conditions, the first spring 46 is in a compressed state, and after the temperature-sensitive release element 42 is thermally exploded, the wedge 45 is rapidly ejected from between the two fixing surfaces under the elastic action of the first spring 46, so that the two fixing surfaces can be rapidly recovered, and the window closer can rapidly complete the window closing operation.
In order to protect the temperature-sensing release element 42, a certain buffer member may be disposed between the temperature-sensing release element 42 and the wedge 45, in this embodiment, a stop block 43 and a second spring 44 are disposed between the temperature-sensing release element 42 and the wedge 45, one side of the stop block 43 is fixedly connected with one end of the temperature-sensing release element 42, the other side is fixedly connected with one end of the second spring 44, and the other end of the second spring 44 is fixedly connected with the wedge 45.
It is not difficult to find that, because the positioning device 4 in this embodiment is disposable, it adopts an integral packaging design, is integrally installed, is convenient to disassemble and assemble, is convenient to replace or maintain, and reduces maintenance cost.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and are not intended to limit the scope of the present invention, for example, the present embodiment specifically illustrates that the window closer is mounted on a window, but not that the window closer cannot be mounted on a window to implement the window closing function, and such equivalent mounting or transformation shall fall within the scope of the present invention. That is, all equivalent changes or modifications made in accordance with the spirit of the present invention should be included in the scope of the present invention.
