Description

Two-purpose spring bolt

The utility model relates to a kind of inside and outside all spendable night bolt of window.

Existing window night bolt complex structure, heaviness, the manufacturing cost height can only be used on the exterior window, can not be used on the interior window.

Task of the present utility model provides a kind of simple in structure, and cost is low, the dual-purpose night bolt that inside and outside window all can use.

Task of the present utility model is achieved in that it is made up of pin boss, fixed head, pin rod, spring and key seat, it is characterized in that: punching press has pin boss in the middle of metal fixed head front, there is screw on both sides, pin cap with holes is arranged at pin boss top, pin rod and pin tongue are connected as a single entity, there is step its joint portion, being with spring on the pin rod of step epimere puts into pin boss and passes hole on the pin cap and crooked 90 ° length of spring compressed is fixed in the pin boss below pin boss, with the pin tongue supporting be the key seat of band screw, be installed in the opposite of pin tongue.Screw on fixed head and the key seat all is rectangles.Exterior window key seat both sides are right angles, and interior casement bolt seat is the polygonal hole seat.

Fixed head of this night bolt and pin boss, pin cap be because adopt a drawing of metal material, and the pin rod of compression spring is fixed in the pin boss, so simple in structure, cost is low, rotates 180 degree and mix interior casement bolt seat as long as will sell tongue on the window time in being used in.Easy to use, window can be closed in an inclined-plane that bumps the pin tongue, and strong wind scratches window-glass in the time of preventing from effectively not hang window catch.

To describe embodiment in detail below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the rear view of shank of the present utility model.

Fig. 3 is a kind of interior casement bolt seat shape figure of the present utility model.

Referring to accompanying drawing, be pin boss 3 in the middle of the fixed head 1 with the thick drawing of metal sheet of 2-2.5mm, there is rectangle screw 2 on both sides, and pin cap with holes is arranged at pin boss 3 tops.Then pin cap is covered on pin boss 3 to crooked 90 degree of pin boss 3 directions.Pin rod 4 is shaped with pin tongue 5 usefulness instrument bed time processing, is provided with step in its junction.Assembling is enclosed within spring 6 on the pin rod 4 earlier during shank, utilizes to sell tongue 5 and block spring 6 than pin rod 4 thick steps and do not make and move down.The pin rod 4 that will be with spring is again packed into by pin boss 3 end openings, and pin rod 4 passes from the pin cap hole, makes to expose half centimeter long pin tongue 5 inclined-planes below the shank, keeps the pressure of spring, and pin rod 4 bendings 90 degree that expose are above fixed.Mixing key seat 7 or 8 can use on the opposite of pin tongue.Mix right angle key seat 7 when the exterior window, mix key seat 6 during as interior window and will sell tongue and rotate 180 and spend.Screw 2 can adopt the rectangle cylindrical void, can adapt to the window distortion relative position of adjusting pin tongue and key seat in certain scope afterwards.When closing window, as long as an inclined-plane that bumps the pin tongue just can be closed.When opening latch, with hand will sell on carry and can open the window.
