Description

Technical Field

[0001] The utility model relates to the field of doors and windows, and in particular to a parking device with temporary positioning and limiting functions. Background Art

[0002] After opening, doors and windows are usually supported by wind braces to prevent them from closing. Currently, there are two types of wind braces: one uses friction damping to support the door or window, but this method suffers from a decrease in friction damping over time, leading to a decrease in the wind bracing's holding power. The other uses a locking mechanism (such as a locking nut or a strut with a hook) to support the door or window. This method also suffers from a problem: in strong winds, if the locking mechanism is not manually released, the door or window cannot be closed, potentially causing damage. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1As shown, the embodiment discloses a parking device with temporary positioning and limiting function, mainly comprising a support rod 1, a sliding groove 2 and an elastic locking structure 5. The sliding groove 2 can be a groove-shaped metal component designed separately, or can be a metal groove on the door leaf or window leaf. The sliding groove 2 is provided with a sliding block 3 and a limiting block 4. The sliding block 3 is slidingly connected in the sliding groove 2, and the limiting block 4 is fixed in the sliding groove 2 by bolts. One end of the support rod 1 is rotatably connected with the sliding block 3, and the other end of the support rod 1 is rotatably connected with the door frame or window frame, or can be connected with the swing arm of the door and window protector.

[0020] When the window leaf or door leaf is opened to the maximum angle, the limiting block 4 is connected with the sliding block 3 through the elastic locking structure 5. The elastic locking structure 5 temporarily stops the sliding block 3. When the external force (wind force or artificial closing force) exceeds the elastic locking force of the elastic locking structure 5, the limiting block 4 and the sliding block 3 can be separated, thereby realizing the closing of the door or window.

[0021] As shown in Figures 2-3 , the elastic locking structure 5 comprises a movable hook 501 and an elastic locking hook 502. The elastic locking hook 502 is elastically inserted and hooked with the movable hook 501. When the movable hook 501 is in contact with the elastic locking hook 502, the elastic locking hook 502 is elastically inserted and hooked with the movable hook 501 under the action of its own elastic force.

[0022] As a way to realize the elastic hooking and stopping of the movable hook 501 and the elastic locking hook 502, as shown in Figures 4-5 and 5 , the movable hook 501 comprises a first hook head 501-1 and a first hook arm 501-2 connected together. The first hook head 501-1 is in the form of a boss, and the two side walls of the first hook head 501-1 are both inclined surfaces. The first hook head 501-1 can be a trapezoidal protrusion. The slope of the outer side of the first hook head 501-1 is larger, which facilitates the insertion and hooking of the first hook head 501-1 with the elastic locking hook 502.

[0023] The elastic locking hook 502 includes a second hook head 502-1 and a second hook arm 502-2 connected together. The second hook head 502-1 is in the shape of a boss, specifically an angular protrusion. Both sides of the second hook head 502-1 are inclined surfaces; the outer side of the second hook head 502-1 has a steeper slope, which also facilitates the insertion and mating of the second hook head 502-1 with the first hook head 501-1. The second hook arm 502-2 is rotatably connected to the shaft 502-3, and an elastic component 502-4 is provided on the side of the second hook arm 502-2, and the elastic component 502-4 is against the second hook arm 502-2. When the second hook head 502-1 is plugged into the first hook head 501-1, the second hook arm 502-2 drives the second hook head 502-1 to contact the first hook head 501-1 under the action of the elastic component 502-4. At the same time, through the inner inclined surfaces of the second hook head 502-1 and the first hook head 501-1, the separation of the first hook head 501-1 and the second hook head 502-1 is limited to a certain extent.

[0024] When external force acts on the door leaf and forces the sliding block 3 to separate from the limit block 4, the inner inclined surface of the first hook 501-1 will contact and squeeze the inner inclined surface of the second hook 502-1, forcing the second hook 502-1 to swing around the shaft 502-3, and then the first hook 501-1 and the second hook 502-1 are separated. After the two are separated, the second hook 502-1 is reset under the action of the elastic component 502-4, waiting for the next plug-in hook with the first hook 501-1.

[0025] In this embodiment, Figures 2-3 As shown, the elastic assembly 502-4 includes a first elastic element 502-4-1 and a second elastic element 502-4-2. The first elastic element 502-4-1 is located on the same side as the second hook 502-1, and the first elastic element 502-4-1 abuts against the end of the second hook arm 502-2 away from the second hook 502-1. The second elastic element 502-4-2 is located on the opposite side of the second hook 502-1, and the second elastic element 502-4-2 abuts against the end of the second hook arm 502-2 closer to the second hook 502-1. In this embodiment, there are three first elastic elements 502-4-1 and one second elastic element 502-4-2. The first elastic element 502-4-1 and the second elastic element 502-4-2 can be springs.

[0026] like Figures 4-5As shown, in the embodiment, the movable hook 501 is arranged on the sliding block 3, and the elastic locking hook 502 is arranged on the limiting block 4, and the limiting block 4 is provided with a cavity 401 for mounting the elastic locking hook 502. The second hook arm 502-2 and the elastic component 502-4 of the elastic locking hook 502 are located in the cavity, the shaft body 502-3 of the elastic locking hook 502 is fixed in the cavity 401, and the second hook head 502-1 is exposed from the cavity 401, so as to be convenient for being inserted and matched with the first hook head 501-1. The outer wall of the second hook head 502-1 and the inner wall of the cavity are both provided with grooves for positioning the first elastic element 502-4-1 and the second elastic element 502-4-2.

[0027] In the embodiment, the limiting block 4 is provided with an extended limiting convex end 402 at one end close to the sliding block 3, and when the limiting block 4 is connected with the sliding block 3 through the elastic locking structure 5, the limiting convex end 402 is abutted against the sliding block 3, so as to limit the further movement of the sliding block 3, and the maximum opening angle of the window sash or the door leaf in this state. Of course, the maximum opening angle of the window sash or the door leaf can be adjusted after adjusting the position of the limiting block 4 in the sliding groove 2.

[0028] The above-described embodiments are only used for describing the preferred modes of the present application, and do not limit the scope of the present application, and various deformations and improvements on the technical scheme of the present application made by the ordinary skilled in the art without departing from the design spirit of the present application should all fall into the protection scope defined by the claims of the present application.
