Abstract

The utility model relates to an automatic bolt for doors and windows, which comprises a bottom board, a handle, a spring, a guide frame, and a pin head. The utility model is characterized in that the handle (6) passes through a slot hole (11) of the bottom board and enters the guide frame (8) from the other slot hole (11) of the bottom board to hook a hook hole (10) of the pin head; the front end of the bottom board is provided with two bolt feet; a bolt button which is matched with the bolt feet is provided with two fork openings; the facade of the guide frame is sealed. When the automatic bolt for doors and windows is used, rain water can not immerse into the guide frame to avoid the spring and the pin head in the guide frame from rusting after a long-term use. Compared with the existing bolt, the utility model has the advantages of reasonable structure, low cost, easy fabrication, and reliable use. The utility model is an ideal automatic bolt for doors and windows and is suitable for various wooden doors and windows.

Description

Automatic bolt and bolt hole for door and window

The utility model relates to a kind of automatic pinning and eye-splice thereof, is applicable to various wooden construction door and windows.

With the more approaching automatic pinning of the utility model as shown in Figure 1, comprise pin head (1), saddle (2), spring (3) and handle (4), handle enters in the saddle from the saddle front window, the pin head is connected with handle employing screw rod.Because the saddle front has the window that allows handle enter, thereby is installed on the door and window, outdoor rainwater enters in the saddle easily, and ponding gets rusty spring, and influence pin head is movable.In addition, pin head is attacked screw after making by turning, matches with screw rod (handle), thereby processes cumbersomely, and production efficiency is lower, and plastic-blasting will carry out after each parts assembling for another example, the technology trouble, and scrappage is higher.

The utility model purpose is to overcome the defective of above-mentioned door and window automatic pinning, provides a kind of saddle positive face closure, and the pin head is novel door and window automatic pinning and the eye-splice thereof that hook is connected with handle.

For achieving the above object, the utility model adopts following technical scheme: handle enters in the saddle from the latch base plate, and hook hole on the pin head, the saddle front can be sealed like this, rainwater can not invaded in the saddle, the back-moving spring and the pin head that are positioned at saddle can not got rusty, have result of use preferably.Pin head is hook with handle and is connected simultaneously, and component processing and assembling are easier to, but assemble behind each parts plastic-blasting again, raising finished product rate.

Below in conjunction with embodiment and accompanying drawing thereof technology contents of the present utility model is described further.

Fig. 2 is the structural representation of the utility model door and window automatic pinning embodiment.

Fig. 3 is the vertical view of Fig. 2 door and window automatic pinning.

Fig. 4 is the left view of Fig. 2 door and window automatic pinning.

Fig. 5 is the eye-splice front view of Fig. 2 door and window automatic pinning.

Fig. 6 is the left view of Fig. 5 eye-splice.

By figure, this door and window automatic pinning comprises base plate (5), handle (6), spring (7), saddle (8), pin head (9), the pin head is positioned at saddle and is withstood by spring, the afterbody of pin head (9) has dog hole (10), and handle (6) passes base plate slotted eye (11) and enters the dog hole (10) that hooks the pin head in the saddle (8) from another slotted eye (12).When door and window was closed, latch was under thrust, and a pin front end inclined-plane slides in the eye-splice window, and spring tightly withstands the pin head, when opening door and window, with portable handle, contracted behind the pin head, left eye-splice, and the pin head resets under spring action then.

After making latch insert eye-splice, eye-splice can not provoked, and the front end of the base plate of the automatic pinning of present embodiment (5) is provided with two pins (16), and the eye-splice that matches with it (13) is provided with the prong (14) that allows pin insert.When the pin head of latch entered the window (15) of eye-splice, the pin of latch also inserted in the prong of eye-splice, and tightly eye-splice is lived in embedding, and eye-splice can not provoked, and made latch more reliable.

Each parts punching out of this door and window automatic pinning and eye-splice thereof forms, and cost is low, and efficient height, base plate and saddle are installed composition, yield rate height with other parts after assembling earlier plastic-blasting. This automatic pinning front does not intake, and latch cooperates firmly with eye-splice. Rational in infrastructure than existing similar automatic pinning, cost is low, easily manufactured, use reliably, be a kind of comparatively ideal door and window automatic pinning, be applicable to various wooden doors and windows.

Claims (3)

1, a kind of door and window automatic pinning, comprise base plate, handle, spring, saddle, pin head, the pin head is arranged in saddle and is withstood by spring, it is characterized in that pin head (9) afterbody has dog hole (10), handle (6) passes base plate slotted eye (11) and enters the dog hole (10) that hooks the pin head in the saddle (8) from another slotted eye of base plate (12).

2, door and window automatic pinning according to claim 1 is characterized in that the front end of base plate (5) has two pins.

3, the eye-splice of door and window automatic pinning according to claim 2 is characterized in that eye-splice (10) is provided with the prong (14) that allows pin insert.
