Embodiment 1

[0060] refer to Figure 1 to Figure 6 As shown, a multi-point lock body includes: a housing, a first lock tongue 4, a second lock tongue 5, an external connection drive mechanism, a first drive mechanism for driving the first lock tongue 4, and a linkage mechanism , In this embodiment, the first lock tongue 4 is an oblique lock tongue, and the second lock tongue 5 is a square lock tongue;

[0061] The first lock tongue 4 is slidably connected with the housing, and a first elastic member 24 is arranged between the two to make the first lock tongue 4 exposed to the housing; as an example, a conical spring is used as the The end of the first elastic member 24 with the smaller outer diameter of the conical spring abuts the first locking tongue 4, so that the first elastic The elastic coefficient of the component 24 is gradually reduced with its compression, that is, during the process of retracting the first lock tongue 4 into the housing, the increased force required to rotate t...

Abstract

The invention discloses a multi-point lock body. The multi-point lock body comprises a shell, a first spring bolt, a second spring bolt, an external connection driving mechanism, a first driving mechanism for driving the first spring bolt to act and a linkage mechanism, wherein the shell is provided with a mounting part; the mounting part is used for being provided with a second driving mechanismfor driving the second spring bolt to act; and the second driving mechanism is rotated to drive the linkage mechanism to act, so that the linkage mechanism drives the first driving mechanism and the external connection driving mechanism to act.

Description

technical field [0001] The invention relates to a multi-point lock body. Background technique [0002] In the door and window lock system, the lock body is an important part, which can realize the function of locking the doors and windows. The handle adapted to the lock body is pressed down to unlock the oblique bolt. If the general lock body is in the closed and locked state, if the lock cylinder is twisted to make it The dead bolt stretches out of the lock body to enable the safety function of the lock body, and now the handle cannot open the door. [0003] The multi-point lock body in the prior art is generally used to close the door to realize the locking of the oblique bolt. The handle moves upward to drive the multi-point lock to cooperate with the lock seat to realize the external lock point locking, and the rotation of the lock cylinder links the square bolt to extend to realize the square lock. The tongue is locked, that is, the safety function. At this time, press...
