[0024] The following is combined with Figure 1-5 The utility model is further described.

[0025] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0026] Reference Figures 1 to 5 The utility model provides a tissue specimen 6 embedding box, including an upper cover 1 and a base 2, the base 2 and the inner side of the upper cover 1 cooperate with each other, and the upper cover 1 and the base 2 are relatively independent, and the two are in a structure that can be separated up and down, and a snap structure 3 is provided between the upper cover 1 and the base 2 to achieve the connection between the upper cover 1 and the base 2. The upper cover 1 and the base 2 are independent of each other and are connected by the snap structure 3, which not only ensures the connection between the upper cover 1 and the base 2, but also enables the base 2 and the upper cover 1 to move independently of each other. When the upper cover 1 is not needed, the base 2 and the upper cover 1 can be disassembled after the connection and fixation of the snap structure 3 are released, and the integrity of the base 2 and the upper cover 1 can be ensured after disassembly, and the next use will not be affected, and the base 2 and the upper cover 1 can be reused.

[0027] Specifically, the buckle structure 3 includes an elastic hook 31 and a hook portion 32. The elastic hook 31 is arranged on opposite sides of the upper cover 1, and the elastic hooks 31 on both sides are symmetrically arranged. The hook portion 32 is arranged at the bottom of the base 2. When the upper cover 1 is installed on the base 2, the elastic hook 31 is clamped on the hook portion 32 to achieve the connection and fixation between the upper cover 1 and the base 2.

[0028] Reference Figure 3 and with Figure 4 The upper cover 1 is fixedly connected with elastic paddles 11 on opposite sides, and the elastic hooks 31 on both sides are respectively fixedly arranged on the corresponding elastic paddles 11. The elastic paddles 11 are elastic structures made of elastic materials, such as metal spring structures. When the upper cover 1 needs to be installed or removed, the elastic paddles 11 on both sides are simultaneously moved in the direction of bringing the two elastic paddles 11 closer to each other, and the elastic paddles 11 on both sides drive the elastic hooks 31 to disengage from the hooking parts 32 to release the connection between the upper cover 1 and the base 2. At this time, the upper cover 1 and the base 2 can be removed and separated.

[0029] Furthermore, the elastic paddle 11 is in an inverted "J"-shaped structure, wherein one of the two opposite sides of the inverted "J"-shaped structure is a fixed end, and the other side is a free end, wherein the fixed end of the elastic paddle 11 is fixedly connected to the upper cover 1, and the connection portion between the free end and the fixed end of the elastic paddle 11 abuts against the surface of the base 2. The elastic hook 31 is fixedly connected to the side of the free end of the elastic paddle 11 facing away from the upper cover 1. When in use, pinching the free ends of the elastic paddle 11 on the opposite sides with two fingers can make the elastic buckle detach from the hook portion 32, and the operation is simple and labor-saving. It should be noted that the elastic paddle 11 can also be in other structural forms, which can achieve the purpose of driving the elastic hook 31 to detach from the hook portion 32, and the present application does not limit the structural form of the elastic paddle 11 to a single limit.

[0030] Reference Figure 2 , Figure 3 and Figure 5 The base 2 is fixedly connected with a limiting plate 21, which is symmetrically arranged on opposite sides of the base 2. The upper cover 1 has corresponding limiting grooves 12 on opposite sides. The limiting block cooperates with the limiting grooves 12. When the upper cover 1 and the base 2 are completely closed, the limiting plate 21 can contact each other at the top of the limiting grooves 12, thereby limiting the upper cover 1 of the embedding box. The limiting plate 21 and the limiting grooves 12 are arranged to limit the upper cover 1 while positioning the upper cover 1. The user can accurately install the upper cover 1 on the base 2, and when the limiting plate 21 abuts against the top of the limiting grooves 12, it can also remind the user that the upper cover 1 has been installed in place, and the elastic paddle 11 can be released so that the elastic hook 31 is buckled with the hook portion 32. In this embodiment, the limiting grooves 12 and the elastic paddle 11 are arranged on different sides of the upper cover 1 to ensure that the limiting plate 21 and the elastic hook 31 do not interfere with each other during use.

[0031] The base 2 is a boss-shaped structure, and an embedding cavity is formed between the inner top surface of the upper cover 1 and the upper surface of the base 2, and the tissue specimen 6 is placed in the embedding cavity for detection. When the upper cover 1 and the base 2 are completely closed, the inner top surface of the upper cover 1 and the upper surface of the base 2 can press and limit the tissue specimen 6, which is conducive to the various processes of the tissue specimen 6.

[0032] The base 2 and the upper cover 1 cooperate with each other, and the upper cover 1 and the base 2 are both provided with evenly distributed through holes 4 on the outside, that is, the upper cover 1 and the base 2 are both hollow structures. Such a configuration is conducive to the use of the embedding box for wax dipping, embedding and other processes of the tissue specimen 6, so that the tissue specimen 6 can be fully in contact with the solution. The base 2 is fixedly connected with a fixing ear 5, and the fixing ear 5 extends to the outside of the upper cover 1. The fixing ear 5 can be provided with a fixing through hole to facilitate fixing or limiting with other detection structures. When there is an operation that requires fixing the embedding box, the embedding box can be fixed in the corresponding structure by the fixing ear 5, and the realization and use of the overall function of the embedding box are not affected. In this embodiment, two fixing ears 5 are provided, and the two fixing ears 5 are symmetrically arranged on opposite sides of the base 2, and the fixing ears 5 and the hooking portion 32 are located on different sides of the base 2 to avoid the fixing ears 5 affecting the realization of the function of the hooking portion 32.

[0033] Furthermore, the base 2 and the upper cover 1 are both made of metal materials. In actual production, metal materials resistant to reagent corrosion can be selected to make the base 2 and the upper cover 1. The base 2 and the upper cover 1 made of metal materials have high structural strength and reliable structure, which is conducive to ensuring the reuse of the embedding box. The surface of the base 2 and the upper cover 1 is plated with a protective layer, which can be achieved by spraying paint or the like. The protective layer covers the surface of the upper cover 1 and the base 2, further protecting the base 2 and the upper cover 1, and further reducing the possibility of corrosion by the reagent. The embedding box with the above structure can be reused repeatedly after cleaning, which is conducive to avoiding waste of resources.

[0034] The implementation process of the utility model is:

[0035] When in use, take out the upper cover 1 and the base 2, place the tissue specimen 6 on the upper surface of the base 2, pinch the free ends of the elastic paddles 11 on both sides with two fingers, so that the elastic hooks 31 on both sides are in an open state, then align the limiting grooves 12 with the limiting plates 21 and press down the upper cover 1 to close the upper cover 1 and the base 2. At this time, release the free ends of the elastic paddles 11 so that the elastic hooks 31 are clamped on the hooking parts 32 to ensure the stability of the upper cover 1 and the base 2 after closing, so as to complete the connection between the upper cover 1 and the base 2; similarly, when it is necessary to separate the upper cover 1 and the base 2, pinch the elastic paddles 11 with two fingers here so that the elastic hooks 31 are disengaged from the hooking parts 32. At this time, the upper cover 1 can be removed from the base 2, completing the assembly, sealing and disassembly process of the entire tissue specimen 6 embedding box.

[0036] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
