[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-3The illustrated double-layer blister tray includes a base 1 and a top cover 2. The base 1 is disposed at the bottom of the top cover 2. A first support block 3 and a second support block 4 are fixedly connected to opposite sides of the base 1 and the top cover 2, respectively. A locking assembly 5 is disposed between the first support block 3 and the second support block 4. The locking assembly 5 includes a first connecting plate 51, a first positioning plate 52, a second connecting plate 53, a second positioning plate 54, and a snap-fit ​​assembly 55. One end of the first positioning plate 52 is fixedly connected to the first connecting plate 51. One side of each of the first support block 3 and the second support block 4 has a connecting hole that matches the first positioning plate 52, thereby locking the two first positioning plates on one side of the first connecting plate 51. Positioning plate 52 engages with first support block 3 and second support block 4 to lock the first support block 3 and second support block 4, thereby ensuring the stability of the installation of base support 1 and top cover 2. One end of second positioning plate 54 is fixedly connected to second connecting plate 53. The other end of first positioning plate 52 is provided with positioning holes that match second positioning plate 54. Two second positioning plates 54 on one side of second connecting plate 53 can lock the first support block 3 and second support block 4 again. Snap-fit ​​component 55 is provided on the side of first connecting plate 51 facing second connecting plate 53. Snap-fit ​​component 55 is used to lock first positioning plate 52 and second positioning plate 54.

[0031] Furthermore, the first support block 3 and the second support block 4 are located between the first connecting plate 51 and the second connecting plate 53. The sides of the first support block 3 and the second support block 4 are provided with hidden grooves. The first connecting plate 51 and the second connecting plate 53 are respectively fitted into the inside of the hidden grooves. That is, the opposite side of the first connecting plate 51 and the second connecting plate 53 is parallel to the sides of the first support block 3 and the second support block 4 to avoid protruding parts.

[0032] In particular, the snap-fit ​​assembly 55 includes a fixed housing 551, a connecting block 552, and a locking rod 553. One side of the fixed housing 551 is fixedly connected to the first connecting plate 51. The opposite side of the first support block 3 and the second support block 4 is provided with a slot that matches the fixed housing 551. One end of the locking rod 553 is fixedly connected to the connecting block 552. The locking rod 553 is snapped between the first positioning plate 52 and the second positioning plate 54. The first positioning plate 52 and the second positioning plate 54 are provided with locking grooves that match the locking rod 553. The outer wall of the locking rod 553 is slidably inserted into the fixed housing 551. The locking rod 553 can ensure the stability of the connection between the first positioning plate 52 and the second positioning plate 54, thereby ensuring the stability of the connection between the first connecting plate 51 and the second connecting plate 53.

[0033] Furthermore, the snap-fit ​​assembly 55 also includes a take-up shaft 554, a connecting rope 555, and a knob 556. The take-up shaft 554 is rotatably connected to the inside of the fixed housing 551. The end of the connecting rope 555 is fixedly connected to the take-up shaft 554 and the connecting block 552. The knob 556 is fixedly connected to one end of the take-up shaft 554. A groove matching the knob 556 is provided on one side of the first connecting plate 51. By inserting a rectangular wrench into the knob 556, the knob 556 drives the take-up shaft 554 to rotate. The take-up shaft 554 winds up the connecting rope 555, which in turn pulls the connecting block 552 and the locking rod 553 toward the inside of the fixed housing 551, thereby unlocking the first positioning plate 52 and the second positioning plate 54, and thus disassembling the first connecting plate 51 and the second connecting plate 53.

[0034] Furthermore, the snap-fit ​​assembly 55 also includes a fixing rod 557, a fixing block 558, and a limiting spring 559. The fixing rod 557 is fixedly connected to the inside of the fixing housing 551, and the fixing block 558 is fixedly connected to the side of the connecting block 552. Only one side of the two connecting blocks 552 is fixedly connected to the fixing block 558. The outer wall of the fixing rod 557 is slidably inserted into the fixing block 558. The limiting spring 559 is slidably sleeved on the outside of the fixing rod 557. The limiting spring 559 is located on the side of the fixing block 558 away from the locking rod 553. The limiting spring 559 can exert an elastic compressive force on the connecting block 552 through the fixing block 558, thereby causing the connecting block 552 to drive the locking rod 553 to maintain a stable snap-fit ​​state with the first positioning plate 52 and the second positioning plate 54.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
