[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cake blister packaging box with a stable inner support, comprising a box body, the inner side of the box body is slidably connected to the inner support, the interior of the box body and below the inner support is rotatably connected to a rotating rod, the middle section of the rod body of the rotating rod is fixedly connected to a locking hook, the bottom of the inner support is fixedly connected to a locking ring, the locking ring is plugged into the locking hook, the end of the rotating rod located on the outside of the box body is fixedly connected to a knob, the inside of the knob is slidably connected to a bayonet, the bayonet is engaged with the box body, and a spring is provided inside the knob.

[0007] Preferably, the number of the locking ring and the locking hook are both two, and the positions of the locking ring and the locking hook correspond to each other. Through the arrangement of the locking ring and the locking hook, a locking effect is provided for the inner support.

[0008] Preferably, the upper edge of the inner support is provided with two easy-to-take slots, and the two easy-to-take slots are symmetrically distributed. The arrangement of the easy-to-take slots facilitates the removal of the inner support from the box body.

[0009] Preferably, one end of the spring is fixedly connected to the bayonet, and the other end of the spring is fixedly connected to the inner surface of the knob. By setting the spring, elastic force can be applied to the bayonet.

[0010] Preferably, a support frame is fixedly connected to the inner bottom of the box body, and the support frame is in contact with the inner support. The arrangement of the support frame provides support for the placement of the inner support on the box body.

[0011] Preferably, the right section of the rod body of the rotating rod is fixedly connected to a limiting ring, and the limiting ring contacts the inner wall of the box body. The setting of the limiting ring has a lateral limiting effect on the rotating rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model provides two locking rings at the bottom of the inner tray, and then provides a rotatable rotating rod in the box body, and the rotating rod is provided with two locking hooks, and the positions of the locking hooks correspond to the locking rings. In this way, the locking hooks can be inserted into the locking rings by rotating the rotating rod, thereby restricting the inner tray and preventing the inner tray from falling off when the user opens the packaging box with excessive force, thereby ensuring the safety of the cake stored in the inner tray.

[0014] 2. The utility model provides a knob at one end of the rotating rod located outside the box body, and a latch supported by a spring is provided inside the knob. The latch will be locked into the outer wall of the box body under the action of elastic force, so that the knob can be locked to a certain extent, and then the rotating rod can be locked, thereby ensuring the stability of the inner support locking.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 A cake blister packaging box with a stable inner tray comprises a box body 1, an inner tray 2 being slidably connected to the inner side of the box body 1, and two easy-to-take slots 21 being provided on the upper edge of the inner tray 2, and the two easy-to-take slots 21 being symmetrically distributed. The provision of the easy-to-take slots 21 facilitates the removal of the inner tray 2 from the box body 1. A rotating rod 3 is rotatably connected to the interior of the box body 1 and below the inner tray 2, a locking hook 4 being fixedly connected to the middle section of the rotating rod 3, and a locking ring 5 being fixedly connected to the bottom of the inner tray 2, the locking ring 5 being plugged into the locking hook 4, the number of both the locking ring 5 and the locking hook 4 being two, and the positions of the locking ring 5 and the locking hook 4 corresponding to each other. The provision of the locking ring 5 and the locking hook 4 provides a locking effect on the inner tray 2.

[0023] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 The end of the rotating rod 3 located on the outside of the box body 1 is fixedly connected to the knob 7. The inside of the knob 7 is slidably connected to a latch 8, which is engaged with the box body 1. A spring 9 is provided inside the knob 7. One end of the spring 9 is fixedly connected to the latch 8, and the other end of the spring 9 is fixedly connected to the inner surface of the knob 7. By setting the spring 9, the elastic force can be applied to the latch 8. The inner bottom of the box body 1 is fixedly connected to a support frame 10, and the support frame 10 is in contact with the inner support 2. The setting of the support frame 10 has a supporting effect on the placement of the inner support 2 in the box body 1.

[0024] The right section of the rod body of the rotating rod 3 is fixedly connected to a limiting ring 6, which contacts the inner wall of the box body 1. The setting of the limiting ring 6 has a lateral limiting effect on the rotating rod 3.

[0025] The specific implementation process of the present invention is as follows: when in use, the inner tray 2 is placed in the box body 1 and supported by the support frame 10, and then the rotating rod 3 is rotated by the knob 7, so that the locking hook 4 on the rotating rod 3 is screwed into the locking ring 5 at the bottom of the inner tray 2, and at this time, the latch 8 in the knob 7 will be stuck into the outer wall of the box body 1 under the action of the spring 9, so that the inner tray 2 can be locked, thereby preventing the inner tray 2 from falling off when the user opens the packaging box with too much force, thereby ensuring the safety of the cake stored in the inner tray 2.
