Description

The Cipher bolt that anti-children fall down from the building

Technical field

The utility model relates to a kind of locking switch device on the push pull type window, the Cipher bolt that specifically a kind of anti-children fall down from the building.

Background technology

The existing password latch does not break away from the on-off mode of original latch, operation inconvenience, and practicality is not strong, children's incident of falling down from the building of windowing happens occasionally, do not prevent that children from climbing the Cipher bolt in mouse building even be specifically designed to, obviously, take double insurance to be very important.

Summary of the invention

The purpose of this invention is to provide the Cipher bolt that a kind of anti-children fall down from the building, to remedy the deficiency of prior art.

The utility model is the improvement on the basis of existing coded lock, therefore, the utility model includes bearing pin and the coded lock of pulling button, and be fixed in the latch box as housing, it is characterized in that the bearing pin left end is provided with a latch body, and the pin-and-hole that this latch body is provided with plugs together mutually and locks with bearing pin, and relies on a spring reset of latch body below fit and undo the lock, and latch body top is positioned at the button that the latch box has an adjusting pin hole site outward.

Above-mentioned latch body is that a centre has pin-and-hole, up and down the thin flat sheet of metal of position limiting structure arranged.

The utility model is simple in structure, and cost is low, and is easy to operate, only need simple one by or one pull and get final product switch.Be widely used on the push-and-pull window, cooperate with existing latch to prevent effectively that children from climbing the mouse building, and don't influence any normal use of window.

Description of drawings:

Fig. 1, basic structure schematic diagram of the present utility model.

Fig. 2, installation site of the present utility model schematic diagram.

Wherein, 1 latch body, 2 springs, 3 pin-and-holes, 4 latch boxes, 5 coded locks, 6 buttons, 7 bearing pins 8 are pulled button 9 window crossbeams 10 slots.

The specific embodiment

As Fig. 1, the utility model includes bearing pin 7 and the coded lock 5 of pulling button 8, and be fixed in the latch box 4, it is characterized in that bearing pin 7 left ends are provided with a latch body 1, and this latch body 1 is provided with pin-and-hole 3 and plugs together mutually with bearing pin 7, have again that to insert the slot 10 at screen window top collaborative and lock with latch body 1 lower end, and a spring 2 of relying on latch body 1 below fit resets and undo the lock, and latch body 1 top is positioned at latch box 4 outsides and is provided with the button 6 of adjusting pin-and-hole 3 positions.

Above-mentioned latch body 1 is that a centre has pin-and-hole 3, up and down the thin flat sheet of metal of position limiting structure A, B arranged.Rely on position limiting structure A, B to limit the relative position of pin-and-hole 3 and bearing pin 7.This latch body 1 is with the metal sheet of thickness one millimeter, makes as punching presses such as corrosion resistant plates.Therefore, insert for latch body 1 as long as offer the slot 10 of a shallow cut shape at two ends, window top.

Position as the pin-and-hole 3 of one of locking mechanism on the above-mentioned latch body 1 is to be positioned at latch box 4, has changed the direction of locking according to this.

As Fig. 2, in actual use, rely on the hole C of the utility model both sides, it is mounted on window crossbeam 9 medium positions of screen window upside, and sets coded lock 5.When latch body 1 when button 6 places are pressed, pin-and-hole 3 moves down, bearing pin in the coded lock 57 inserts pin-and-holes 3 automatically and pins latch bodies 1.Bearing pin 7 during the pulling button 8 and pulled to the right of coded lock in the coded lock 5 just withdraws from pin-and-hole 3, and latch body 1 upwards rebounds under the effect of spring 2.

When pressing latch body 1, insert screen window top slot 10, screen window then is lockable.The button 8 of pulling of pulling coded lock 5 upwards rebounds latch body 1, and then screen window can be opened.

Usually as long as fan the common latch pinning glass window of glass window side in one of screen window outside push-and-pull seldom, under the situation that screen window is pinned by Cipher bolt, the glass window latch can not be unlocked outside by the screen window retaining.Be able to double insurance, and another fan glass window of screen window one side still can normally be opened ventilation.

If child is difficult to contact the utility model that window top is provided with, and need frequent switch screen window airing clothes, then can upset or be provided with the password on the coded lock, and only need with hand one by or one pull, can the Convenient switch screen window.

Obviously, the utility model is simple in structure, installs and easy to operate, with low cost, therefore is easy to produce and apply, and can effectively lock the push-and-pull window and prevents that child and other people from arbitrarily coming in and going out.
