Description

Door and window safety rod

Technical Field

The utility model relates to the technical field of window and door accessories of residential buildings, in particular to a limiting safety device suitable for a sliding window and door during closing, opening and ventilation, namely a window and door safety rod.

Background

The safety devices used on the sliding doors and windows used in the field of residential buildings at present are various, and besides various bolts used for locking the sliding doors and windows when the sliding doors and windows are closed, safety technologies such as a sliding window anti-theft chain and the like provide safety protection for the sliding doors and windows. However, the above techniques can only provide security protection in one state. For example, the bolt functions in a state that the sliding door and window is completely closed, and once the sliding door and window is opened, the bolt immediately loses the safety function, so that the disadvantages caused by the bolt are not repeated.

In the push-pull type door and window practical application, the puzzlement needs to be solved, the two opposite technologies need to be compensated, the combined structure can lock the door and window when the push-pull type door and window is closed, and can ensure that the door and window is not opened by people outside the door and window to enter the room when the push-pull type door and window is opened for ventilation, so that the push-pull type door and window has the safety protection effect in the closing and opening states. If the novel technical device is applied to the push-pull type door and window, the safety of the open ventilation state and the close state can be protected.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it is to be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and simplifying the description, but 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 thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Examples

Referring to fig. 1, the present invention discloses a door/window safety bar, which comprises a first element 100, a second element 200 and a fine adjustment jack 300.

Wherein, the first element 100 is tubular, and the tube wall thereof is arranged with a plurality of positioning holes 110 along the length direction; the second element 200 is inserted into the first element 100, an elastic positioning pin 210 is arranged in the second element 200, and the adjustment of different insertion depths is realized by positioning and clamping the elastic positioning pin 210 on different positioning holes 110; the fine adjustment stem 300 is screwed on the protruding end of the second member 200.

That is, when the length of the door/window safety lever needs to be adjusted, only the elastic positioning pin 210 needs to be pressed down, the second element 200 is extended and retracted, when the length is adjusted to a proper length, the elastic positioning pin 210 stops being pressed down, the elastic positioning pin 210 automatically resets at the moment, the door/window safety lever is clamped in a certain positioning hole 110, and the door/window safety lever is in a locking state at the moment. Since there is a minimum spacing of the alignment holes 110 (i.e., the adjustable travel is limited by the spacing of the alignment holes 110 and does not precisely match the actual desired push-up length), the adjustment of the travel within this partial spacing is overcome by fine-tuning the depth of the thread-on of the carrier rod 300.

In this embodiment, the second element 200 is also tubular, is easily available and has a light weight, and provides a convenient adjustment for the installation of the elastic positioning pin 210. The elastic positioning pin 210 comprises a V-shaped spring 211 and a positioning pin 212, one end of the V-shaped spring 211 is fixed in the inner cavity of the second element 200, the other end of the V-shaped spring is connected with the positioning pin 212, and the positioning pin 212 extends out of the tube wall of the second element 200.

In order to prevent the second member 200 from being pulled out of the first member 100, the present invention further includes an inter-pipe bush 400, and the inter-pipe bush 400 is inserted and fixed in the insertion end of the first member 100. The second member 200 is inserted into the inter-pipe bush 400, and a tail of an insertion end thereof is formed with a slip-off prevention catch 220 to catch on an insertion end edge of the inter-pipe bush 400 after the inter-pipe bush 400 is inserted. Thus, when the second element 200 is pulled to the position of the nozzle of the first element 100, the anti-slip buckle 220 abuts on the inserting end edge of the inter-pipe bush 400, and the second element 200 is prevented from slipping off the first element 100.

Specifically, in this embodiment, a bayonet 410 is formed on the inter-pipe bush 400, and a bayonet hole 120 corresponding to the bayonet 410 is formed on the pipe wall of the first member 100, so that the inter-pipe bush 400 is inserted into the insertion end of the first member 100, and the bayonet 410 is inserted into the bayonet hole 120 to complete the bayonet coupling. For ease of insertion, the top of bayonet 410 defines a lead-in ramp 411 in the direction of insertion.

In this embodiment, the tail of the second element 200 is flanged outward to form the anti-falling buckle 220, so that the process is simple and reliable.

To facilitate the fixing of the present invention, a sealing plate 130 is fixed to the non-insertion end of the first member 100, and a bolt hole is formed at the top end of the sealing plate 130, so that the sealing plate 130 can be fixed to a target carrier (e.g., a window frame) by passing a screw through the bolt hole to prevent the sealing plate from falling off. To increase the friction between the first element 100 and the target carrier, a nylon pad 150 is disposed at the bottom of the first element 100.

In this embodiment, the fine adjustment rod 300 includes a cushion 310 (which may be made of rubber) and a screw 320, and the non-insertion end of the second member 200 is welded with the nut 230 to form a threaded hole for screwing the screw 320. Thus, the fine adjustment post 300 can be rotated to change its extension on the second member 200.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
