Hidden bolt structure

Technical Field

The application relates to the technical field of door and window locks, in particular to a hidden bolt structure.

Background

The hidden bolt is one kind of anti-theft part for fixing on door or window to stabilize the door or window when the door or window is closed and to prevent the door or window from being opened from outside. The hidden bolt generally comprises a shell, a driving structure and a bolt rod, wherein the shell is generally arranged in the door and window, the driving structure is arranged in the shell, the bolt rod slides to be arranged in the door and window, and when the bolt rod extends out of the door leaf or the window sash, the bolt rod is inserted into a jack preset on the door frame or the window frame in advance, so that the door or the window can be prevented from being opened. For convenient operation, the common driving structure is arranged on the side frame surface of the door leaf or the window sash, and the operation is convenient, but the attractive appearance is poor.

The related art discloses a hidden bolt structure, including well accuse bolt external member, upper bolt pole and lower bolt pole. When the door and window are required to be locked, the upper bolt rod and the lower bolt rod are driven to extend through the central control bolt sleeve piece at the same time, so that the upper bolt rod is inserted into a socket at the top of the door and window frame, and the lower bolt rod is inserted into a socket at the bottom of the door and window frame, and the locking of the door and window is realized. Although the hidden bolt in the related art realizes double locking of the door and the window, the hidden bolt is easy to cause the blockage of the fixed holes at the bottom of the door and the window frame because dust, soil and the like are easily brought into the fixed holes at the bottom of the door and the window in the process of entering and exiting the door and the window, so that the whole hidden bolt is easy to fail, and meanwhile, when one bolt rod is damaged, the whole hidden bolt is caused to fail.

In order to solve the problem that the fixing sleeve at the bottom end is easy to be blocked, a hidden bolt structure is disclosed in the related art, as shown in fig. 1, the hidden bolt comprises an L-shaped mounting piece 1, an upper bolt rod 101 is slidably arranged on the mounting piece 1, and meanwhile, the distance from the upper bolt rod 101 to the side wall of the mounting piece 1 is very short. In the in-service use process, only the L-shaped mounting piece 1 is required to be mounted at the corner position of the top of the door and window, and meanwhile, only the socket for the upper bolt rod 101 to pass through is required to be arranged at the top of the door and window frame, and the socket is not required to be arranged at the bottom of the door and window frame, so that the technical problem of blockage of the fixing hole is avoided.

Because the hidden bolt includes mounting 1 of L type, consequently install the in-process of door leaf with the hidden bolt, need offer the mounting groove that can supply whole L type hidden bolt to place in the corner position at door and window top, the bolt through-hole is less because the distance between upper bolt pole 101 to mounting 1, generally does not exceed 5cm, then can lead to the locking strength of hidden bolt not strong, is easily relieved by the violence. The preferable scheme is that the upper latch rod 101 is inserted into the door leaf, namely, the greater the distance between the latch rod and the side edge of the door leaf is, the stronger the structural stability is. But this operation can lead to another problem, namely needs the bolt through-hole that sets up in the door leaf to be deeper, can reduce the intensity structure of door, and the mounting 1 of L type is installed in the corner of door leaf simultaneously, belongs to cladding installation, and whole mounting exposes outside the door leaf, influences the aesthetic property and the structural uniformity of whole door.
