DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-5 This application is described in further detail.

[0021] The present application embodiment discloses a built-in lock packaging box. Figure 1-3 , including a box body 1, the box body 1 is used to store the items to be guaranteed, and plug-in slots 2 are provided on both sides of the upper end of the box body 1, and a through hole 3 is provided at one end of the box body 1. Both sides of the through hole 3 are provided with a clamping slot 4, and the cross section of the clamping slot 4 is an L-shaped structure. When the clamping block 94 is located inside the clamping slot 4, it is convenient for the clamping block 94 to be clamped. Fixed rods 5 are connected to both sides of one end of the box body 1, and a limiting groove 6 is provided at one end of the fixing rod 5. When the pull plate 911 is sleeved on the outside of the fixing rod 5, the limiting groove 6 conflicts with the pull plate 911 to limit the pull plate 911. Because the fixing rod 5 is cylindrical and has a relatively smooth exterior, if the pull plate 911 is directly sleeved on the outside of the fixing rod 5, the friction between the pull plate 911 and the fixing plate is small, which makes it easy for the pull plate 911 to slide, affecting the fixing effect. A box cover 7 is connected to one side of the upper end of the box body 1. The box cover 7 protects the goods inside the box body 1 and at the same time The product is closed, and both sides of one end of the box cover 7 are connected with a plug-in board 8, which is adapted to the plug-in slot 2. The plug-in board 8 is inserted into the plug-in slot 2, and the outer sides of the plug-in board 8 are tightly fitted with the inner wall of the plug-in slot 2, so that the friction between the plug-in board 8 and the plug-in slot 2 is increased, thereby enhancing the connection effect between the box body 1 and the box cover 7. One end of the box cover 7 is connected with a locking component 9, and one end of the locking component 9 is connected with a placement seat 91. The placement seat 91 supports the first spring 92, and the placement seat 91 accommodates the mounting block 93. When the mounting block 93 is squeezed, it is convenient to move the mounting block 93 to the inside of the placement seat 91. Both sides of the placement seat 91 are provided with grooves for matching the clamping block 94, which is convenient for the mounting block 93 to drive the clamping block 94 to move to the inside of the placement seat 91. The inner side of the placement seat 91 is connected with a first spring 92, and the first spring 92 supports and contracts the mounting block 93.

[0022] Reference Figure 4-5One end of the first spring 92 is rotatably connected to a mounting block 93. The first spring 92 is rotatably connected to the mounting block 93. When the mounting block 93 rotates, it will not drive the mounting block 93 to rotate. When the first spring 92 supports and contracts the mounting block 93, it will not affect the rotation of the mounting block 93. Both sides of the outside of the mounting block 93 are connected to clamping blocks 94. The mounting block 93 rotates the clamping block 94 so that the clamping block 94 is fixedly connected to the clamping groove 4. Both sides of one end of the mounting block 93 are provided with placement grooves 95. Both sides of the inside of the placement groove 95 are connected to round rods 96. One end of the round rod 96 is connected to a support plate 97, which supports the round rod 96 and limits the moving block 98 to prevent the moving block 98 from being separated from the round rod 96 when moving and falling off from the outside of the round rod 96, thereby limiting the sliding distance of the moving block 98 and ensuring the safe use of the moving block 98. One end of the support plate 97 is connected to one side of the placement groove 95, and the moving block 98 is connected to the outer side of the round rod 96. A second spring 99 is sleeved on one side of the outer side of the round rod 96, and one end of the second spring 99 is connected to one side of the moving block 98. The second spring 99 provides a pulling force on the moving block 98. The pull plate 911 is pulled by the pull plate 911, and the pull plate 911 drives the second spring 99 to stretch, and the pull plate 911 is sleeved on the outside of the fixed rod 5. At this time, the pull plate 911 is fixedly connected to the fixed rod 5, and the second spring 99 generates a pulling force, which pulls the pull plate 911 to contact the fixed rod 5. Under the elastic potential energy of the second spring 99, the connection between the second spring 99 and the fixed rod 5 is more fixed. The other end of the second spring 99 is connected to one side of the placement slot 95. One end of the moving block 98 is connected to the rotating shaft 910, and one end of the rotating shaft 910 is rotatably connected to the pull plate 911. 0, the pull plate 911 can be rotated according to the use requirements, so that the moving direction of the pull plate 911 is not limited to linear movement. When the mounting block 93 is engaged with the through port 3, the fixing rod 5 is flush with the mounting block 93. Directly pulling the pull plate 911 cannot fix the pull plate 911 to the fixing rod 5. By rotating the rotating shaft 910, the pull plate 911 is pulled and rotated to one side, which makes it easier to put the pull plate 911 on the outside of the fixing rod 5. A fixing groove 912 is provided at one end of the pull plate 911, and the fixing groove 912 is adapted to the fixing rod 5.

[0023] The implementation principle of an embedded lock packaging box in the embodiment of the present application is as follows: when in use, the mounting block 93 is pressed, the mounting block 93 squeezes the first spring 92, and under the contraction of the first spring 92, the mounting block 93 moves to the inside of the placement seat 91, at this time, the mounting block 93 is flush with the surface of the box cover 7, the box cover 7 is pressed downward, and the mounting block 93 contacts with the box body 1, when the mounting block 93 moves to the side of the through hole 3, the outside of the mounting block 93 loses pressure, and the elastic potential energy of the first spring 92 pushes the mounting block 93 to move, so that the mounting block 93 drives the card to move to the card slot 4, and the mounting block 93 is rotated, and the mounting block 93 drives the card The connecting block 94 is engaged with the engaging groove 4, and the pulling plate 911 and the fixing rod 5 are in the same horizontal plane. The pulling plate 911 is pulled toward the side of the fixing rod 5. When the pulling plate 911 moves to above the fixing rod 5, the pulling plate 911 is sleeved on the outside of the fixing rod 5 so that the pulling plate 911 is engaged with the limiting groove 6. At the same time, under the pulling force of the second spring 99, the fixing effect is increased. Under the fixed connection of the locking assembly 9, the connection quality between the box cover 7 and the box body 1 is more stable, which avoids the box cover 7 from opening during use of the packaging box, affecting the use of the packaging box. The box cover 7 drives the plug-in plate 8 to move to the inside of the plug-in groove 2, so that the box cover 7 and the box body 1 are initially fixed.
