Abstract

The utility model relates to a spring bolt for doors and windows, which is composed of a bottom board, a pin rod, a handle, and a pin buckle, wherein, the pin rod is arranged on the bottom board; the handle is arranged on the pin rod; the pin buckle is matched with the pin rod; the pin rod is provided with a column spring; the matched end of the pin rod and the pin buckle is designed into a wedge slope structure. Therefore, when wind blows to bring on the closing of doors and windows, the pin rod of the spring bolt automatically retracts backwards and inserts into the pin buckle to lock the doors and the windows and the spring bolt can not damage the doors, the windows, and glass caused by the repeated collision of the doors and the windows.

Description

Spring lock bolt

The utility model relates to a kind of night bolt that is used on door, the window, includes base plate, is contained in the pin rod on the base plate, the pin button that matches with pin rod, the handle of design on pin rod.

At present, being used for door, the common latch on the window is buckled by the pin rod in the positioning sheath that is contained in a base plate, the pin that matches with pin rod, the handle of design on pin rod constitutes, the pin rod of this latch and pin are buckled an end that matches and are designed to tack end face structure with the pin rod axis normal, blow hard when running into, when door and window is closed, pin rod can not be inserted in the pin button automatically, repeatedly very fragile door and window of switch door and window and glass thereof.

The purpose of this utility model just is: design a kind ofly when blowing the self-closing doors window, pin rod is inserted in the pin button automatically, thereby pin is decided the night bolt of door and window, to prevent to damage door and window and glass.

The utility model is to realize its purpose like this: this night bolt includes base plate, is contained in the pin rod on the base plate, the pin button that matches with pin rod and the handle of design on pin rod.A post spring is equipped with in design on pin rod, and pin rod matches with the pin button to hold and is designed to the splitter ramp structure.

The utility model can also be realized its purpose like this: design has two rest pads on base plate, and pin rod is bearing in the hole of this rest pad, and the post spring then is contained in handle and away from that section pin rod between the rest pad of splitter beveled end.

Pin rod of the present utility model, post spring, two rest pads all are positioned at and the base plate pin cap of load mutually, and design has the positioning runner equipped mutually with handle on pin cap.

Owing to the utlity model has the said structure design, a post spring is equipped with in design on pin rod, and the pin rod end that matches with the pin button is designed to the splitter ramp structure, causes when blowing hard, when window is closed, under the wind-force effect, when collide in pin rod splitter beveled end and pin button button limit, contract after forcing pin rod, the splitter beveled end is just inserted in the pin button automatically, then under the effect of post spring, pin rod tightly is pressed in the pin button, thereby has guaranteed not switch and hit and bump repeatedly of door and window, cause the damage of door and window and glass.

Further described below in conjunction with drawings and Examples, but specific embodiments of the present utility model is not limited in the specific descriptions in this example and the accompanying drawing.

Fig. 1 is that axis of no-feathering of the present utility model is surveyed schematic diagram;

Fig. 2 is that the master of the utility model base plate looks, overlooks and right view, i.e. (a) and (b), (c);

Fig. 3 is the utility model pin rod schematic diagram;

Fig. 4 is the utility model pin cap schematic diagram.

As shown in FIG., this night bolt includes base plate (1), pin cap (2), pin rod (3), designs the handle (5) on pin rod (3), the pin button (4) that matches with pin rod (3).Base plate (1) is gone up the rest pad (1A) that design has two supporting pin rods (3), pin rod (3) just is bearing in the hole (1B) on this rest pad (1A), pin rod (3) matches with pin button (4) to hold and is designed to splitter inclined-plane (3A), at handle (5) with on away from that section pin rod (3) between the rest pad (1A) of splitter inclined-plane (3A) end post spring (6) is housed.Pin rod (3), post spring (6), two rest pads (1A) all are in and base plate (1) mutually in the pin cap of load (2), adopt the load of spiral-lock mode phase in this example, and go up design at pin cap (2) positioning runner (2A) that is equipped with mutually with handle (5) is arranged.Pin cap (2) is not an essential feature, during fabrication, can copy common latch structure yet, goes up design one location sheath or groove is protected in the location at base plate (1), can get final product by positioning sliding to guarantee pin rod (3).During installation, note that end that pin rod (3) do not cooperate with pin button (4) should be able to be pin cap (2) in before and after slippage, promptly leave one section slipping space, certainly, also pin cap (2) directly can be designed to cover structure along the groove that the pin rod direction leads directly to.When causing door and window to close when blowing, splitter inclined-plane (3A) end that pin rod (3) matches with pin button (4), when running into the button limit of pin button (4), just contract after forcing pin rod (3), compression post spring (6) is inserted in the pin button (4) pin rod (3) automatically, then under post spring (6) effect, pin rod tightly is pressed in the pin button (4), can cause door and window switch collision and damage door and window and glass repeatedly.In addition, upward also design the screw hole that installation usefulness is arranged on the pin button (4) at base plate (1).

Claims

1, a kind of night bolt that is used on door, the window, include base plate (1), be loaded on the pin rod (3) on the base plate (1), the pin button (4) that matches with pin rod (3), the handle (5) of design on pin rod (3), it is characterized in that: a post spring (6) is housed on pin rod (3), and pin rod (3) matches with pin button (4) to hold and is designed to splitter inclined-plane (3A).

2, night bolt according to claim 1, it is characterized in that: going up design at base plate (1) has two rest pads (1A), pin rod (3) is bearing in the hole (1B) of this rest pad (1A), post spring (6) then be contained in handle (5) and away from splitter inclined-plane (3A) end rest pad (1A) between that section pin rod (3) on.
