[0033] Combination Figure 4 When the door body 5 needs to be closed, at least part of the lock hook 2 abuts against the pushing surface 1201 and pushes the lock tongue 12 to rotate in a first direction until the locking surface 1202 abuts against at least part of the lock hook 2, and the elastic member 13 and the locking surface 1202 apply a pre-tightening force toward the side of the pushing surface 1201 to at least part of the lock hook 2; when the door body 5 needs to be opened, at least part of the lock hook 2 abuts against the locking surface 1202 and pulls the lock tongue 12 to rotate in a second direction opposite to the first direction until the pushing surface 1201 abuts against at least part of the lock hook 2, and the elastic member 13 and the pushing surface 1201 apply a pushing force toward the side of the locking surface 1202 to at least part of the lock hook 2. The first direction is defined as Figure 4 The second direction is defined as the counterclockwise direction in Figure 4 clockwise direction.
[0034] Back to Figure 3In this embodiment, when the lock tongue body 121 rotates along the second direction to abut against the front wall 112, the lock hook 2 is separated from the lock tongue opening 120, and when the lock tongue body 121 rotates along the first direction to abut against the rear wall 113, the lock hook 2 abuts against the locking surface 1202. In this embodiment, the rear wall 113 is provided with an abutting strip 1130 extending along the length direction of the lock body 1 towards the front wall 112, and the abutting strip 1130 has two strips and is respectively close to one of the seat walls 111, and the abutting strip 1130 is provided with a limiting surface for abutting against the side of the lock tongue body 121 away from the front wall 112 towards the front wall 112. In other embodiments, the abutting strip 1130 can be formed by the seat wall 111.
[0035] In this embodiment, the rotating body 122 includes two rotating blocks 1221 set at an angle, the two rotating blocks 1221 are connected and form a folded corner 1222, the folded corner 1222 abuts against the inner wall of the rotating hole 3, and one end of one of the rotating blocks 1221 away from the folded corner 1222 also abuts against the inner wall of the rotating hole 3.
[0036] The two rotating blocks 1221 are vertically connected, and the distance between the corner 1222 and one end of the rotating blocks 1221 away from the corner 1222 is less than the opening length of the notch 30, so that when the lock tongue 12 is placed in the accommodating cavity 110, the rotating body 122 can slide from the notch 30 into the rotating hole 3.
[0037] Reference Figure 4 and Figure 5 The perpendicular bisector of the line between the corner 1222 and one end of one of the rotating blocks 1221 away from the corner 1222 passes through the rotating point B of the rotating body 122 in the rotating hole 3.
[0038] The position where the elastic member 13 and the rear stop wall 113 are connected is the rotation point C, which is a relatively fixed rotating end. The position where the elastic member 13 and the lock tongue body 121 are connected is the rotation point A, which is a movable rotating end rotating around the rotation point C.
[0039] In the projection parallel to the rotation axis of the bolt body 121 , the rotation point B of the rotating body 122 is located within the range of a circle with the fixed rotating end as the center and the line between the fixed rotating end and the movable rotating end as the radius.
[0040] In this embodiment, the lock hook 2 is in the form of a rectangular ring, and the lock hook 2 is fixed to the box body 4 or the door body 5 by a nut.
[0041] In this embodiment, the rotating body 122 is inserted into the rotating hole 3 from the notch 30 so that part of the lock tongue body 121 is located in the accommodating cavity 110, and then one end of the elastic member 13 is hung in the hole of the rear baffle wall 113, and the other end is hung in the hole of the side wall of the lock tongue body 121 close to the front baffle wall 112.
[0042] The pushing surface 1201 of the locking tongue opening 120 causes the locking hook 2 to rotate in a first direction when the locking tongue opening 120 is closed, and the locking surface 1202 of the locking tongue opening 120 causes the locking hook 2 to rotate in a second direction when the locking tongue opening 120 is opened.
[0043] Rotation point B and rotation point C are fixed rotation points, rotation point A rotates counterclockwise or clockwise with rotation point B as the center under the action of lock hook 2, and rotation point A1 during the rotation process is on the straight line connecting rotation point B and rotation point C so that the three points are collinear, and this rotation point A1 is the critical point for clockwise or counterclockwise rotation. Rotation point A2 is the lowest point of the clockwise rotation of the lock tongue 12, and rotation point A3 is the highest point of the counterclockwise rotation of the lock tongue 12. The principle of this embodiment is that when the lock tongue 12 is closed, the thrust of the lock hook 2 causes the lock tongue 12 to rotate counterclockwise. As long as it is separated from the critical point of rotation point A1, the lock hook 2 will be tightened by the locking surface 1202 under the pulling force of the elastic member 13, thereby tightening the door body 5. When the door is opened, the pulling force of the lock hook 2 causes the lock tongue 12 to rotate clockwise. As long as it leaves the critical point of the rotation point A1, the lock hook 2 will be pushed away through the pushing surface 1201 under the pulling force of the elastic member 13, so that the lock hook 2 and the lock tongue 12 are separated.
