Description

Spring bolt

The utility model belongs to the particularly latch of window of housing window.

Latch can be fastened with a bolt automatically in order to realize closing window, alleviate the suffered vibrations of glass when closing window simultaneously, many, functions different in the patent application of China, occurred bigger improved latch has but been arranged with traditional structure, the latch that wherein is used in wooden window is maximum for number, but great majority still adopt the latch to be contained on the sash to insert the form of fastening with a bolt in the key seat hole in the window frame that is contained in, the shortcoming of this latch be except often may can not enter door bolt because of sash deformation, and is difficult to metal window.Some are exclusively used in the latch on the metal window in addition, and performance is also good, but also is difficult for being applicable to wooden window.And many latch parts are more, make complexity, and processing cost is higher.

The purpose of this utility model is to provide that a kind of metal and wooden window can both be suitable for, night bolt simple in structure and practical.

The utility model is realized its purpose as follows: the base plate of latch housing (4) has an elongated slot (8), and this elongated slot embeds in the interior cavity of pin boss (1), and latch also has a dihedral key seat (2).

Night bolt of the present utility model has been drawn the strong point of multiple different latches, simplifies its structure as much as possible, makes latch not only reliably be applicable to various metals or wooden window easily, and number of spare parts is few, is mainly plate stamping spare, labor and material saving, low processing cost, the utmost point is beneficial to penetration and promotion.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is the general assembly schematic perspective view of this night bolt.

Fig. 2 is the structural representation of pin.

Fig. 3 and Fig. 4 are respectively the structural representations of pin boss and base plate.

Fig. 5 is a dihedral key seat schematic diagram.

The housing of latch is made up of pin boss 1 and base plate 4, and pin 3 can vertically move in housing; Between the tapered end 5 of pin 3 and handle end 7, spring 6 is arranged; A groove 8 that connects full plate is arranged on the base plate 4, and the width of groove is can embed groove 8 the rectangular cavity degree of being of pin boss 1, and the degree of depth can be equivalent to the thickness of metal window window bar or window frame.When the utility model latch is used for wooden window, just can use dihedral key seat 2, the length of dihedral key seat 2 can be random.When latch of the present utility model is used for metal window, latch directly is contained on the bonding jumper of sash and gets final product, both can horizontally adorn, also can erect dress; Sash can latch automatically when closing window, pin 3 pull-ups can be pushed open sash and got final product by handle end 7 when windowing.If latch of the present utility model is used for wood windows,, also need the corresponding place on window frame to load onto dihedral key seat 2 then except will on sash, installing the latch; Close window and window step and metal window together.Because key seat has adopted dihedral, eliminated because of pin does not cause the possibility of fastening the window difficulty with a bolt or latch to going up the key seat hole, make the pass window very convenient reliable.
