Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.
Referring to fig. 1 to 8, an embodiment of the short-distance window closer of the present invention includes a mounting frame 1, a rocker arm 2 and a trip device 3, wherein a reset power slider 4 is arranged on the mounting frame, a body of the rocker arm is connected with the mounting frame in a shaft way, one end of the rocker arm is connected with one end of a connecting rod 111 in a shaft way, and the other end of the connecting rod is connected with the reset power slider in a shaft way; the connecting rod plays a role in transmitting push-pull force, when the window frame is used, the mounting frame is fixed at a window frame and the like, the rocker arm and the window sash are fixed (of course can be reversely installed), the window sash is opened, the rocker arm rotates along a pivot point which is connected with the mounting frame, the connecting rod which is connected with the shaft can be given with force application when rotating, because the manual thrust of a person is larger than the resistance of the reset power sliding block, the reset power sliding block avoids and stores energy, at the moment, the connecting rod and the rocker arm are matched to form a compression included angle A, under the angle, the rocker arm can apply force to the reset power sliding block, and the reset power sliding block also acts on the rocker arm to reset the rocker arm and rotate towards the window closing direction; when the compression included angle is larger than 180 degrees, the connecting rod and the rocker arm are matched to form a reset included angle B, under the angle, the rocker arm can continuously rotate towards the windowing direction due to actual force according to the direction of force application, therefore, a limiting part 5 is arranged on the mounting frame positioned on one side of the reset included angle, the limiting part can limit the rocker arm to continuously rotate, under the condition of blocking, the force application of the reset power sliding block can not be completely released, and the fixed angle windowing effect is realized, and the force application direction is shown in fig. 6; when the window needs to be closed, the window sashes are directly pulled to be closed, referring to fig. 8, when the reset included angle is changed into the compression angle and no window opening force is applied, the force applied by the reset power sliding block can act on the rocker arm through the connecting rod, so that the rocker arm is reset, the automatic window closing effect is achieved, and after the window sashes are closed, the force applied direction schematic diagram is shown in fig. 4.
The transmission scheme of above-mentioned power adopts connecting rod and swing arm one end structure cooperation to form, and this structure is small to adopt the cooperation of spacing portion, effectively carry out the spacing of windowing, thereby realize the effect that can fix a position the windowing and close the window automatically.
Because the window closer needs to automatically close the window under the conditions of fire and the like, a tripping device is adopted to trigger the reset included angle to reset towards the compression included angle, and certain acting force is given to the window closer, so that the automatic window closing effect can be realized by rotating the rocker arm by a small angle.
Referring to fig. 3, the above-mentioned power slider that resets includes movable block 6, guide bar 7, fixed guide block 8 and spring 9, and the movable block sets up in guide bar one end, and fixed guide block cover is established on the guide bar and is fixed to be set up on the mounting bracket, and the spring setting is between movable block and fixed guide block, and when compression contained angle moved towards the contained angle that resets, the spring compression energy storage. When the window is opened, the moving block moves in position, the spring can be compressed, deformation energy storage is achieved, and when the moving block moves, the guide rod and the fixed guide block cooperate to achieve the smooth and stable movement effect. And the number of the guide rods is at least 2, so that the stability is further improved, the end parts of the guide rods are fixedly connected through the movable blocks 10, the shaking of the guide rods during movement is reduced, and the friction loss is reduced.
For the smoothness when closing the window, the movable block is also connected with the buffer 11, the buffer is arranged on the mounting frame, and the buffer enables the energy storage of the spring to be released slowly, so that the window sash can be closed slowly, and the use experience is improved.
The trip device may be multiple types, may be an electronic temperature sensing assembly, or may be a mechanical mechanism, and in particular, this embodiment provides a mechanical manner, including a trigger plate 12, a trip 13, and a trigger portion 14, where the trigger portion is disposed on a rocker arm, and the trip drives the trigger plate to move and pushes the trigger portion to move. The trigger plate contacts with the rocker arm, the area is up, and the stability is good.
Wherein, the release includes spring post 15, clamp plate 16 and temperature sensing glass pearl 17, and temperature sensing glass pearl is with clamp plate one end butt on the mounting bracket, and the clamp plate other end is used for compressing the spring post and is provided with the portion of dodging on the mounting bracket that corresponds. When the spring column is used, one end of the pressing plate presses the column body of the spring column into the mounting frame, and the other end of the pressing plate is abutted against the mounting frame by the temperature-sensitive glass beads so as to ensure that the displacement cannot be caused, and the spring column is shown in reference to FIG. 5; when the temperature sensing glass beads meet the height Wen Suilie, referring to fig. 7, the pressing plate has no supporting force, the column body of the spring column is released and stretches out, the pressing plate can avoid movement due to the avoiding part, and when the spring column stretches out, the trigger plate can be pushed out of the trigger plate by the spring column to move so as to drive the rocker arm to move, so that the rocker arm moving effect is achieved. Specifically, one end of the trigger plate is connected with the mounting frame in a shaft way, the other end of the trigger plate is arranged between the spring column and the pressing plate, and the contact position of the trigger part and the trigger plate is positioned at one side of the trigger plate connected with the mounting frame in a shaft way; the trigger plate can not rotate wantonly, is compressed tightly by the clamp plate and has realized spacing to when triggering the rocker and removing, the trigger plate can be regarded as lever structure, and contact position can increase the promotion effect of trigger plate, guarantees that the extension force of spring post can promote the rocker and remove, reaches the effect of automatic closing window.
The positioning groove is formed in the surface of the pressing plate, the end portion of the temperature sensing glass bead is matched with the positioning groove, the pressing plate is pressed against the mounting frame in a higher stability, and the position of the pressing plate cannot move. And be provided with the activity on the mounting bracket and dodge the spacing groove, the connecting axle that is connected usefulness between rocking arm and the connecting rod passes the activity and dodges the spacing groove setting, and the removal of rocking arm can dodge the spacing groove through the activity and prescribe a limit to, and the range of movement is more accurate.
The above embodiments are merely preferred embodiments for fully explaining the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present invention, and are intended to be within the scope of the present invention. The protection scope of the invention is subject to the claims.
