Abstract

The utility model relates to an ejecting type window-bolt with a spring pin function used for a door or a window. The aim of the utility model is to pin or open the door and the window by an ejecting function of a spring. The bolt is composed of a sliding disk, a socket rod, the spring, a link board, a sealed casing, a spring clamper and a socket hole. When the door and the window are pinned, the sealed casing is downwards drawn, and thus, the door and the window can be tightly inserted by the bolt. When the door and the window are opened, the sealed casing is pressed by figures, and thus, the bolt can be ejected to the original position automatically. The ejecting type window-bolt has the advantages of easy and labor saving operation, beautiful appearance, scientific structure, and low cost.

Description

Ejection type window latch

The utility model relates to a kind of latch that is used for door or window that the spring catch effect is arranged.

At present, the latch that is used for both at home and abroad wooden door or window on the building materials market is common directly to inject jack type with inserted link mostly, and the head that this latch needs to pinch inserted link with two fingers in use is with the inserted link reeve or withdraw from jack, and is very hard, use inconvenience, and external form is not attractive in appearance yet.Ejection type window latch yet there are no to be reported.

The purpose of this utility model is to utilize launching the effect pinning or opening door and window of spring, and is easy and simple to handle laborsaving, and aesthetic in appearance generous, and the latch structure science is cheap, and very high economic benefit and social benefit are arranged.

In order to achieve the above object, the ejection type window latch of the utility model design is to be assembled by sliding plate, inserted link, spring, connecting plate, closed housing, spring card, jack.

Advantage of the present utility model:

1. utilize the effect of launching of spring, when the mortise lock door and window, pull down the closed housing latch and just can be seated door and window, with pointing one by closed housing, latch just can launch playback automatically, and is simple to operation when opening door and window.

2. all component do not need welding on the latch, do not need screw to be connected with rivet yet, and assembling is simple, science rational in infrastructure, and manufacture technology is simple, cheap.

3. bottom of Fixed latches sliding plate gong silk at window, owing to be vertical with latch direction, so solid and reliable as pin, assurance safety.

4. can spray paint, electroplate or enamel on the surface of closed housing, adorn horizontal modification house and have a distinctive flavour.

Closed housing 1 upper plate 8 is 90 ° and turns up among Fig. 3, and closed housing 1 biside plate has two pairs 90 ° The bending 9,10 (such as Fig. 2) of doubling.

90 ° at the end of sliding plate 2 is outwards turned up among Fig. 4, on a circular hole 11 (such as Fig. 5) is arranged, sliding Dish 2 the other end also has a

circular hole

12,13 to pass sliding plate 2 and 90 ° for the two caudas boring of spring card 6 Separately put down folding (such as the C-C sectional schematic diagram), 14,15,16,17 are respectively sliding plate 2 outside two The double-vane of 90 ° of bendings of side (such as D-D, E-E, F-F sectional schematic diagram). Double-vane 14 and double-vane 15 Crooked height is on the same level face, and double-vane 16 is slightly more shallow than double-vane 15 bendings, and double-vane 17 is than two The wing 16 bendings more shallow, and slightly go up bending.

Front 1/3 place's centre of connecting plate 3 has one perpendicular to 90 ° of connecting plate 3 horizontal directions among Fig. 6 The stator 18 of bending, 90 ° of the other ends are bent into flap 20, and rear 1/3 place has one upwards to bend 19 (such as Fig. 7).

One end of Fig. 8 upper plunger 4 has the groove 21 of a slotting stator 18, and both sides, groove 21 bottom have two to dash forward Play ears 22.

The side plate 23 of jack 7 can be made various shapes as required (such as various inserting on Fig. 9 on Fig. 9 Hole and schematic side view thereof), circular hole 24 is arranged on the side plate 23.

The utility model embodiment:

Closed housing 1, sliding plate 2, connecting plate 3, spring card 6, jack 7 all adopt the cold drawing steel of 0.7～1.5 millimeters thick carbon structure among Fig. 1, punching press on mould earlier, shaping boring again.

Spring card 6 will strike out semiclosed bending earlier, two caudas 13 is passed sliding plate 2 each 90 ° separately flat roll over (as C-C sectional schematic diagrams) again.

Inserted link 4 adopts that the cold drawn steel of 6 millimeters carbon structures of Φ is disconnected through car, squeeze out ears 22 after the groove milling 21 forms.

Spring 5 adopts 0.8 millimeter spring steel wire of Φ through turning to, and the external diameter of corresponding inserted link 4 and length dimension form through heat treatment again.

At last assemble ejection type window latch:, again top board 8 is upwards rolled over 90 ° of bendings closed housing 1 top closure is lived with the closed housing 1 of packing into after connecting plate 3, inserted link 4, spring 5, sliding plate 2 assemblings as Fig. 1.

During use, with

circular hole

12,13 on the screw insertion sliding plate 2 and the circular hole 23 on the jack 7, latch is fixed earlier.During the mortise lock door and window, closed housing 1 is drawn to next, top board 8 just tightly withstands flap 20, connecting plate 3 is pushed up downwards, stator 18 on the connecting plate 3 is owing on the groove 21 that is stuck on the inserted link 4, so just inserted link 4 is pushed up downwards, because spring 5-holds on the ears 22 that are stuck on the inserted link 4, the other end is stuck on the spring card 6, so compression spring 6 when inserted link 4 pushes up downwards, spring 6 is the reaction top sliding plate 2 that makes progress just, and double-vane 14 on the

sliding plate

2,15,16 just bendings 9 on the closed shell 1 that binds, 10 upwards slide, and the bending 19 on the last connecting plate 3 is outwards pushed up double-vane 16, the upper end of bending 9 is just blocked in the lower end of double-vane 16, sliding plate 2 stops to slide, and inserted link 4 is gone into jack 7, and door and window is stuck in.When drawing back door and window, the closed housing 1 that press...withes one's finger, double-vane 16 just slips into the bending 9 on the closed housing down on the sliding plate 2, and closed housing 1 upwards slides under spring 5 rebound effects, and inserted link 4 just along with upwards breaking away from jack 7, is opened door and window.Cauda 13 works to prevent that with double-vane 17 sliding plate 2 from sinking in the closed housing 1.
