Abstract
A bolt switch of a sash window or door is characterized in that a hole (14) in the base (4) is concentrically corresponding to a pin hole (12) of the window frame or door frame (7, 8); a pin (3) matches with the hole (14) and the pin hole (12) of the window frame or door frame (7,8); a pin post (3) is provided on the pin (3); the shape of the hole (14) of the base (4) meets the need of access and exit of the pin (3) and the pin post (2); a handle is provided at the end of the pin (3). The utility model has the advantages of reasonable design, simple structure, convenience and practicality; the bolt switch can increase the safety of the sash window or door.
Description
Technical field
The utility model relates to the pick-proof plug-in switch of a kind of push pull type window or door.
Background technology
The switch that push pull type window of installing in now a lot of units, the family or door use is easy to occur that jump ring comes off or phenomenon such as iron sheet deformation of hook in long-term use.And this switch is easily damaged and loses the effect of switch when push-and-pull in the other direction firmly, and also can open voluntarily at this switch in vibration back repeatedly, and safety is relatively poor.So a lot of users are installed the reinforcing bar protective screening protective action that tightens security again additional outside push pull type window.Like this, both increased user's expense, influenced attractive in appearancely, do not met the requirement of fire department again, and a kind of condition of ascending a height was provided also can on the contrary the criminal that enters the room.
The content of utility model
The technical problems to be solved in the utility model is for overcoming the deficiency described in the background technology, and a kind of rational in infrastructure, the safe and reliable push-and-pull window or the pick-proof plug-in switch of door are provided.
Technological improvement plan of the present utility model is:
Hole at base is concentric corresponding with the hole of window frame or doorframe, and pin cooperates with pin-and-hole on hole and window frame and the doorframe, also is provided with a pin on pin.
Further technological improvement of the present utility model is:
The Kong Weike of base satisfies the shape of pin and pin turnover.End at pin has one handle.Base is fixedlyed connected with window frame or doorframe.
By the above Technological improvement plan good effect that the utility model produced as can be seen: this switch designs is reasonable, simple in structure, convenient and practical, durable, mainly be that safety is stronger, rotating after pin inserted in the hole just can be locked with pin again, can't be outside window with this switch opens, even pin can not be pulled out from window or door the inside, have only the osculum on pin mating holes top just can be pulled out pin.Go up and just can improve its security performance so this switch is installed in push pull type window or door, window also need not install protective screening additional outward again, and the spending with the minimizing user more meets the requirement of fire department.

The specific embodiment
Fig. 1, Fig. 2 show the concrete structure of an embodiment of the utility model.Base 4 is provided with a hole 14, and also leaves an osculum 13 that can make pin 2 turnover above hole 14.Base 4 is fixedlyed connected with window frame or doorframe 7,8 by screw or rivet 5.Also be provided with on overlapping window frame or the doorframe 7,8 one with base 4 on the pin-and-hole 12 of hole 14 concentric settings, but the pin-and-hole on outermost window frame or the doorframe 7 does not connect.The pin 3 that is connected as a single entity with handle 1 can insert and extend in the pin-and-hole 12 of window frame or doorframe 7,8 by hole 14, can be one with two fan windows or door bolt so just, can not produce displacement.Designed a pin 2 vertical at the afterbody of pin 3 with pin 3, this pin 2 can enter in the base 4 by the osculum on the hole 14 13, handle 1 being rotated a little to make pin 2 be stuck in the base 4 again, spur handle 1 and also pin 2 can not pulled out this moment, has only turning handle 1 again and make pin 2 aim at osculum 13 just can be drawn out.
Fig. 3 is the structure of another embodiment.Can in a fan window frame or doorframe 7,8, establish a sleeve 10 and spring 9 again, and on pin 3, establish a snap ring 11.Behind pin 3 patchholes 14 and pin-and-hole 12, snap ring 11 pressuring springs 9 on the pin 3, twisting handle 1 make pin 2 and osculum 13 dislocation realize self-locking.When needs are pulled out pin 3, only need pin 2 is aimed at osculum 13, make the action of pulling out pin 3 more flexible because the effect of spring 9 will be ejected pin 3 automatically this moment.
In order to confirm the direction of pin 2 easily, on handle 1, can do a mark, or coat a point, or process one and pin 2 equidirectional ribs.
Also can base 4 is fixing with screen window 6, and on screen window 6, make a call to a pin-and-hole, pin 3 is penetrated and realize locking (referring to Fig. 1).
Claims (4)
1, the pick-proof plug-in switch of a kind of push-and-pull window or door, it is characterized in that in the hole (14) of base (4) concentric corresponding with the pin-and-hole (12) of window frame or doorframe (7,8), pin (3) cooperates with pin-and-hole (12) on hole (14) and window frame and the doorframe (7,8), also is provided with a pin (2) on pin (3).
2, the pick-proof plug-in switch of push-and-pull window as claimed in claim 1 or door is characterized in that the top in the hole (14) of base (4) is provided with the osculum (13) that can make pin (2) turnover.
