Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door and window fittings, in particular to a pull rod device for an inwardly tilting heavy window and a door and window assembly. BACKGROUND

[0002] The part provided in this part is only background information related to the present application to facilitate those skilled in the art to understand the present application more thoroughly and accurately, which does not necessarily exist in the prior art.

[0003] The casement inwardly tilting window can be brought into three different states of locking (handle vertically downward), casement (handle horizontally) and inwardly tilting (handle vertically upward) by rotating the door and window handle to drive the linkage hardware inside the door and window.

[0004] At present, most of the casement inwardly tilting windows do not have a buffer structure, and when the casement inwardly tilting window is tilted inwardly, the connecting piece on the window is easily damaged due to excessive force, thereby reducing the service life.

[0005] Therefore, the application number 202410141938.9 discloses a translation inwardly tilting window with a damper, which comprises an upper connecting piece and a damper, the upper connecting piece is arranged between the inner top wall of the window frame and the top of the window sash, and the upper connecting piece comprises a sliding piece sliding along the horizontal direction of the window frame; the damper is located on the sliding path of the sliding piece, so that when the translation inwardly tilting window is tilted inwardly, the sliding piece acts on the damper and compresses the damper. Therefore, when the above structure is adopted, since the damper is arranged, when the window is opened inwardly, the sliding piece will act on the damper to compress the damper, and the damper can provide good buffering effect to prevent the upper connecting piece from being damaged due to excessive force when the window is tilted inwardly.

[0006] However, although the damper can buffer the door and window when the window is opened inwardly, the damper cannot assist in closing the window when the window is closed. For heavy window sashes with large volume and heavy weight, the user still needs to use more force to push the window sash to close. For the elderly or children, it is very inconvenient to operate.

[0023] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the accompanying drawings in the embodiments of the present application.

[0024] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the modules or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application is only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0026] Embodiment one Referring to Figures 1-4 The present application provides a pull rod device for inwardly tilting heavy window, which is arranged on a door and window and respectively connected with a door and window frame 13 and a heavy window sash 12, and the inwardly tilting heavy window sash 12 or closing the window can be realized by the pull rod device; specifically, the pull rod device comprises a pull rod seat 1, a pull rod 2 and a long rotating rod 3, the pull rod seat 1 is fixed on the top of the sash frame of the heavy window sash 12, and a sliding groove 101 extending along the length direction of the pull rod seat 1 is formed in the pull rod seat 1; the pull rod 2 is arranged in the sliding groove 101 and can move along the extension direction of the sliding groove 101; one end of the long rotating rod 3 is pivotally connected with the pull rod 2 and the pivot point can move along the extension direction of the sliding groove 101, and the other end of the long rotating rod 3 is pivotally connected with the door and window frame 13; the elastic member is arranged in the pull rod seat 1 and transmissionally cooperates with the pull rod 2.

[0027] When the window is opened inward, the long rotating rod 3 rotates, and the pivot joint between the long rotating rod 3 and the pull rod 2 moves to one side of the extension direction of the sliding groove 101, that is, the long rotating rod 3 drives the pull rod 2 to move to one side of the extension direction of the sliding groove 101 and synchronously compresses the elastic member. The elastic force provided by the elastic member can offset part or all of the gravity of the heavy window sash 12, avoid the heavy window sash 12 from being quickly opened inward to generate a large force, and thus play a buffering effect, prevent the internal parts of the pull rod device from being damaged, and prolong the service life.

[0028] When the window is closed inward, the long rotating rod 3 rotates back, and the pivot joint between the long rotating rod 3 and the pull rod 2 moves to the other side of the extension direction of the sliding groove 101, that is, the long rotating rod 3 drives the pull rod 2 to move to the other side of the extension direction of the sliding groove 101, and at this time the elastic member synchronously releases the elastic force. The released elastic force can assist the closing of the heavy window sash 12, so that the user can easily close the heavy window sash 12, the operation is convenient and labor-saving, and the experience is good.

[0029] Therefore, the elastic member arranged in the pull rod device can not only buffer the heavy window sash 12 when the window is opened inward, but also assist the closing of the heavy window sash 12 when the window is closed inward, achieving two effects at one time.

[0030] Referring to Figures 2-3 , specifically, the pull rod device further comprises a sliding block 7 arranged at one end of the pull rod 2 and slidingly arranged in the sliding groove 101, and one end of the long rotating rod 3 is pivotally connected to the sliding block 7 through a pin shaft.
