Description

Spring bolt

The utility model relates to a kind of bolt device of improved latch, particularly a kind of spring.Be suitable for door, window use.

Existing latch is made up of iron plate, L type cylinder and semicircle iron ring.The latch of selling on the market is exactly this form.After door is shut, lock door lock, plug latch again, can make door be difficult for prizing, strengthen defence, increase the sense of security.Also sell a kind of multi-functional door lock in addition on the market.Its existing door lock has latch again, and structure is complicated, and price is more expensive.But the door and the window that have, as long as the device latch needn't use door lock, then multi-function door lock is just inapplicable.

Task of the present utility model provides a kind of improved latch, and it installs spring, and changes the box latch into by " barebacked " latch.

Task of the present utility model is finished as follows: the shell of being made up of microscler iron casket and square iron casket.Microscler iron casket has an opening, and cleek is equipped with in the upper right corner.Microscler iron casket interior arrangement spring and tongue, there is the iron plate head center, tongue right side.When cleek hooks the iron plate head, tongue just contracts in microscler iron casket.Dial from the iron plate head when cleek, tongue just puts in the square iron casket.

Simple structure of the present invention, easy to use, when the example structure that will describe in detail below adopting, profile is by box replacement " barebacked "; Use replaces hand to dial by spring; Bearing thrust is strong.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.

Fig. 2 is the iron casket stereogram of Fig. 1.

Fig. 3 is the tongue stereogram of Fig. 1.

With reference to Fig. 1, a shell of forming by microscler iron casket 1 and square iron casket 2.Microscler iron casket 1 and square iron casket 2 relative two whole openings in side, other side seals.Square iron casket 2 extends iron pin 3 up and down, and microscler iron casket 1 extends iron pin 3 up and down and iron pin 3 is extended in the side.1--2 small sircle hole 4 respectively arranged, so that fix on the iron pin 3 with screw.Microscler iron casket 1 has an opening 5, and the length of opening 5 is longer than square iron casket 2 slightly, and width is 1/3rd of a microscler iron casket 1.At opening 5 upper right corner device cleeks 6, cleek 6 usefulness nail is fixed on the microscler iron casket 1.But the unsuitable tension of nail, tension then cleek 6 can not rotate.Microscler iron casket 1 interior arrangement spring 7 and tongue 8.Spring 7 one ends are fixed on microscler iron casket 1 side, and an end withstands tongue 8.The height of tongue 8 and width are slightly less than microscler iron casket 1, and length is consistent with opening 5 right sides.There is an iron plate 9 tongue 8 right sides centers, and iron plate 9 is cylinder, exceeds microscler iron casket 1, and top hemisphere is bigger than cylinder, and cleek 6 is hooked can landing.

When not using, cleek 6 hooks iron plate 9, spring 7 compressions, and tongue 8 contracts in microscler iron casket 1.During use, 6 groups of cleeks are from iron plate 9, and the spring 7 of compression just ejects immediately, and tongue 8 immediately puts in the square iron casket 2, shows on the latch pin.

Claims

1, improved latch, particularly a kind of night bolt device, feature of the present utility model is the shell that microscler iron casket 1 and square iron casket 2 are formed, microscler iron casket 1 has an opening 5, at opening 5 upper right corner device cleeks 6, microscler iron casket 1 interior arrangement tongue 8, tongue 8 right sides centers have an iron plate 9, and iron plate 9 exceeds microscler iron casket 1.

2, according to the described night bolt device of claim 1., it is characterized in that microscler iron casket 1 inside is equipped with spring 7, spring 7 one ends are fixed on microscler iron casket 1 side, and an end withstands tongue 8.
