[0042] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0043] like Figures 1 to 5As shown, a flip oblique lock bolt device provided by the present invention comprises an oblique lock bolt, an oblique lock bolt locking slider, an oblique lock bolt fixed support guide rod, an oblique lock bolt locking slider toggle assembly, a first spring and a support plate, wherein: one end of the oblique lock bolt fixed support guide rod is detachably connected to the oblique lock bolt, it should be noted that the oblique lock bolt fixed support guide rod is hingedly connected to the oblique lock bolt, and the oblique lock bolt can achieve reversal, and the oblique lock bolt is limited by the panel of the lock body to avoid being ejected from the lock body. The oblique lock bolt fixed support guide rod passes through the oblique lock bolt locking slider and passes through the support plate; the oblique lock bolt locking slider toggle assembly is preferably fastened to the oblique lock bolt fixed support guide rod, and is arranged in the oblique lock bolt locking slider, and may not be arranged in the oblique lock bolt locking slider, mainly realizing the toggle function of the oblique lock bolt locking slider. The first spring is sleeved on the oblique lock bolt fixed support guide rod, and the two ends of the first spring are respectively against the oblique lock bolt locking slider toggle assembly and the oblique lock bolt locking slider. It should be noted that the first spring can act on the oblique lock bolt locking slider through other media. In addition, the first spring may not be sleeved on the oblique tongue fixing support guide rod, as long as the elastic pressure can act on the oblique tongue locking slide block.

[0044] Further, a receiving area is provided in the middle of the back of the oblique lock tongue, and a rotating shaft area is provided on both sides of the receiving area. A rotating shaft perpendicular to the oblique lock tongue fixed support guide rod is provided at one end of the oblique lock tongue fixed support guide rod, and the rotating shaft is provided in the rotating shaft area. The oblique lock tongue can rotate 40-70 degrees relative to the oblique lock tongue fixed support guide rod. The receiving area is preferably a semi-cylindrical area, and the end of the oblique lock tongue fixed support guide rod is also semi-cylindrical. Therefore, when the oblique lock tongue fixed support guide rod is provided in the receiving area of ​​the back of the oblique lock tongue, the oblique lock tongue can realize a rotation connection relative to the oblique lock tongue fixed support guide rod. And the semi-cylindrical sides of the end of the oblique lock tongue fixed support guide rod are provided with rotating shafts, which rotate in cooperation with the rotating shaft area of ​​the oblique lock tongue.

[0045] In more detail, the back of the oblique lock tongue is also provided with a stop block, and the oblique lock tongue locking slide block is provided with an abutment block that cooperates with the stop block. When the stop block overlaps the abutment block, the oblique lock tongue is locked; when the stop block is separated from the abutment block, the oblique lock tongue is activated. Figure 2 and Figure 3 The anti-rotation blocks are arranged on the left and right sides of the back of the oblique lock tongue, and the bottom of the anti-rotation blocks is provided with an inclined surface. The back of the oblique lock tongue is provided with a reset guide block, and the oblique lock tongue locking slider is provided with a reset guide surface matching the reset guide block, and the oblique lock tongue is reset by the cooperation of the reset guide block and the reset guide surface.

[0046] More specifically, the front panel of the oblique bolt locking slider is provided with a through hole, and abutment blocks and reset guide surfaces are provided on both the left and right sides of the through hole, and the abutment blocks and reset guide surfaces on both sides are symmetrical about the center of the through hole. Through the central symmetrical structural design of the front panel, the reset function can be achieved regardless of whether the oblique bolt is flipped forward or reverse.

[0047] In more detail, the oblique bolt device of the present invention further comprises a tail plate, which is arranged at the other end of the oblique bolt fixed support guide rod. It also comprises a second spring, one end of which abuts against the tail plate, and the other end of which abuts against the panel accommodating the oblique bolt fixed support guide rod. When the oblique bolt fixed support guide rod moves outward in the axial direction, the support plate can block the tail plate, preventing the oblique bolt from separating from the lock body. The oblique bolt locking slide block toggle assembly is driven by the toggle assembly and reciprocates, and the oblique bolt locking slide block toggle assembly can drive the oblique bolt locking slide block to move.

[0048] The working principle of the present invention is as follows: in the initial state, that is, when the door is in the closed state, the oblique lock tongue and the oblique lock slider are in a locked state. When the door is opened, the oblique lock slider toggle assembly is driven to move by the toggle assembly, and the oblique lock slider toggle assembly drives the oblique lock tongue to move, so that the oblique lock tongue is away from the oblique lock slider, and then the oblique lock tongue is in an activated state. After the door is opened, the oblique lock tongue is rotated to the left and right by a certain angle by the external force of the door frame and is in a flipping state. When the oblique lock tongue is in the flipping state, the reset guide block on the back of the oblique lock tongue cooperates with the reset guide surface on the oblique lock slider, so that the oblique lock slider can achieve the reset function of the blood lock tongue through the cooperation of the reset guide block and the reset guide surface when moving forward. And even if it is not coordinated by the oblique lock slider, when the door is closed, under the guidance of the door frame, the oblique lock tongue can achieve the reset function.

[0049] The first spring force of the present invention acts on the oblique bolt locking slider, so that the oblique bolt locking slider has a forward thrust. When the oblique bolt locking slider is pushed backward by the toggle assembly, the oblique bolt is flipped and unlocked. At this time, the user pulls the door and the oblique bolt flips, and the inclined surface of the bolt is squeezed against the side of the bolt hole on the door frame to make the oblique bolt retreat into the lock body, so that the door is opened. However, when the toggle assembly does not exert force, the first spring force acts on the oblique bolt locking slider to generate a forward thrust. The thrust guides the oblique bolt to flip and reset, and at the same time acts on the oblique bolt fixed support guide rod, and the oblique bolt fixed support guide rod pushes the oblique bolt out. When the door is opened, the oblique bolt has pressure on the inclined surface of the oblique bolt locking slider. Because there is a suitable slope, the backward thrust caused by the pressure offsets most of the friction. Therefore, the toggle assembly only needs to overcome the remaining small friction and the elastic force at the end of the spring and only needs to move a distance of about 3mm to unlock. The power consumed in this process is much less than the energy consumption consumed by not having an angle or pushing the oblique bolt to move a distance of about 20mm to completely retreat. The guide rod for fixing the inclined bolt also plays a guiding role in driving the inclined bolt. At the same time, when the inclined bolt is subjected to a strong external shear force, it becomes a good long lever to resist the shear force, thereby improving the shear resistance strength of the inclined bolt.
