Abstract

The utility model discloses an automatic spring bolt device for wings, which is particularly suitable for windows. The automatic spring bolt device is characterized in that the bolt rod of the bolt is matched with a spring, and under the elasticity of the spring, a bolt head returns automatically for self locking. The utility model solves the problems that an original straight line type movable bolt has difficulties in opening and closing, and is not able to carry out the self locking. The utility model has the advantages of convenient operation, beautiful appearance, and material saving.

Description

Automatic spring bolt

The utility model relates to a kind of wing that is used for, and especially for the bolt device of window, at present, generally the window latch of Cai Yonging is the straight line mobile model latch that does not have spring action.Its weak point is mainly reflected in: can not self-locking when closing, firmly bigger during breakdown, in addition service time long cause keying more difficult owing to get rusty; Secondly, the materials amount is big, and profile is not attractive in appearance.

Task of the present utility model provides a kind of conveniently opening and closing, and materials are few, good looking appearance, and have the automatic pinning of spring action.

Its solution is: utilize inclined-plane pin head to buckle slip at pin, by the spring force effect on the pin rod, make inclined-plane pin head self-return self-locking.During breakdown, only need to pull at pin handle, make in the inclined-plane pin head retraction pin boss, promote window more gently and get final product by the straight trough position on the pin boss.

Specifically, pin rod puts a slide and a spring, is connected with inclined-plane pin head then, and it is held in addition a cap, and during assembling, the pin rod cap separates with the interior fixedly card of pin boss with slide.

By above-mentioned improvement, solve window and opened and closed difficult defect, another characteristics of the present utility model are that materials are few, aesthetic in appearance.

Accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is the structure chart of auto spring latch;

Fig. 2 is the vertical view of auto spring latch pin boss;

Fig. 3 is the right view of auto spring latch pin boss;

Fig. 4 is the elevation of pin button.

With reference to Fig. 1, Fig. 2, Fig. 3, auto spring latch of the present utility model buckle (6) by pin boss (1), pin handle (2), pin rod (3), spring (4), inclined-plane pin head (5) and pin and form.Pin boss (1) is " T " font, and three end points are hole, a garden (13) respectively, makes the usefulness of location; One straight trough (14) is arranged at its top, puts pin handle (2), and pin handle (2) is lifted one's head and stator (7) riveting knot.Pin rod (3) is the garden cylindricality, and an end has a cap (8), puts slide (9) and spring (4) afterwards, and the other end adopts with inclined-plane pin head (5) and is threaded or gluing connecing.During assembling, slide (9) pressing spring (4) is stuck on the interior fixedly card (10) of pin boss (1), pin handle (2) is lifted one's head stator (7) between pin rod cap (8) and slide (9), and is slidingly matched, and covers base plate (11) again.

With reference to Fig. 4, pin is tipped pin head outlet (15) size that mouthful (12) size is slightly larger than pin boss (1) in, and hole, a garden (3) is respectively bored on both sides, during installation, notices that tipping the pin head outlet (15) of pin boss in mouthful (12) with pin aligns, and is convenient to pin head self-return.

Auto spring latch of the present utility model adopts metal material, and the pin head is made preferable of aluminium alloys, pin boss, pin handle chromium plating, and all the other inner bodies are zinc-plated, can be antiseptic and rustproof.

Claims

1, a kind of bolt device that is used for the window keying, it comprises pin boss [1], pin rod [3] and pin button [6] three parts, and feature of the present utility model is: pin rod [3] one ends have a cap [8], put slide [9] and spring [4], and the other end is connected with inclined-plane pin head [5].

2, device according to claim 1 is characterized in that pin rod (3) is threaded or gluing connecing with inclined-plane pin head (5) employing.

3, according to claim 1 described device, it is characterized in that a straight trough (14) is arranged at pin boss (1) top, there is the fixedly card (10) of a limit slippage sheet (9) at the middle part in the shell.
