Technical Field

[0001] This utility model relates to the field of embedding box assembly technology, specifically an embedding box upper and lower cover positioning and assembly device. Background Technology

[0002] Embedding cassettes are standard containers used in pathology laboratories to hold tissue samples for paraffin embedding. They are typically made of heat-resistant plastic. Their core function is to provide physical support and protection for fragile samples during complex processes such as tissue dehydration, clearing, and paraffin embedding, and to ensure the traceability of sample information through surface writing areas or labels.

[0003] In the prior art, the patent announcement number CN202422248270.6 discloses a pathological embedding box, including a bottom shell, a top cover provided on the top of the bottom shell, a connecting seat fixedly connected to one side of the bottom shell, and a first through hole opened inside the bottom shell; a limiting component is provided inside the bottom shell, and the limiting component includes a triangular sponge.

[0004] The embedding cassette mainly consists of a bottom shell and a top cover, which are connected by a pivot. During assembly, workers first need to appropriately open the pivot seat on the bottom shell to allow sufficient space. Then, the pivot on the top cover is accurately and securely inserted into the pivot seat on the bottom shell. This fitting method achieves a tight connection between the bottom shell and the top cover, ultimately completing the assembly process of the embedding cassette. To improve assembly speed, a positioning and assembly device for the upper and lower covers of the embedding cassette is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a positioning and assembly device for the upper and lower covers of an embedding box, so as to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and assembly device for the upper and lower covers of an embedding box, comprising a base, a slot seat on one side of the base, and a sliding groove seat on the other side of the base. A bottom shell is placed in the slot seat, and a top cover is placed in the sliding groove seat. A positioning mechanism is installed on the slot seat. The positioning mechanism includes a movable sliding groove formed on the slot seat and a cylinder fixedly installed at one end of the base. A sliding support foot is slidably installed in the movable sliding groove. A limit block is fixedly installed at the upper end of the sliding support foot. A linkage rod is fixedly installed at the output end of the cylinder. The sliding support foot is slidably installed on the linkage rod. An expansion component is installed on the sliding groove seat.

[0007] Preferably, a spring is sleeved on the linkage rod, and a limit ring is fixedly installed on the linkage rod.

[0008] Preferably, a sliding hole is provided in the middle of the sliding support leg, and the sliding support leg is slidably installed on the linkage rod through the sliding hole.

[0009] Preferably, the sliding support leg is slidably installed in the slot seat via a movable slide groove, the limiting block is slidably installed in the slot seat via the sliding support leg, one end of the spring is connected to the sliding support leg, and the other end of the spring is connected to the inner wall of the movable slide groove.

[0010] Preferably, the expansion assembly includes a lifting seat slidably installed in the slide groove seat and a wedge block fixedly installed on the linkage rod. The wedge expansion block is fixedly installed on the upper surface of the lifting seat, and guide rods are fixedly installed at the two side edges of the lifting seat. A tension spring is provided at the lower end of the guide rod, and a wheel frame is fixedly installed at the middle position of the bottom of the lifting seat. A guide wheel is rotatably installed on the wheel frame.

[0011] Preferably, the upper surface of the slide seat is provided with an inlet / outlet hole, and the wedge-shaped extension block extends out of the slide seat through the inlet / outlet hole.

[0012] Preferably, the slide seat has a sliding groove, the guide rod is slidably installed in the slide seat through the sliding groove, one end of the tension spring is fixedly installed at the lower end of the guide rod, and the other end of the tension spring is fixedly installed at the bottom of the sliding groove.

[0013] Preferably, the wedge-shaped expansion block is movably installed in the slide seat via a lifting seat, and the guide wheel is rotatably installed below the lifting seat via a wheel frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, when the cylinder extends, it drives the linkage rod to move forward. After the linkage rod completes its forward movement, the spring returns to its initial state. During the spring's reset process, it pushes the sliding foot forward. As the sliding foot moves forward, it causes the limit block to move forward, thereby firmly locking the bottom shell into the slot, facilitating assembly.

[0015] 2. In this application, after the bottom shell is secured in the slot, the wedge block on the linkage rod can continue to move forward using a cylinder. As the wedge block continues to move forward, it causes the guide wheel to move upward. When the guide wheel moves upward, the lifting seat moves upward synchronously. When the lifting seat moves upward, the wedge-shaped expansion block extends. When the wedge-shaped expansion block extends, it expands the pivot seat on the bottom shell. After the pivot seat expands, it can push the top cover towards the bottom shell, causing the pivot on the top cover to embed into the pivot seat on the bottom shell, thereby achieving rapid assembly of the top cover and the bottom shell.

[0018] 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.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a positioning and assembly device for the upper and lower covers of an embedding box. It includes a base 1, a slot 2 on one side of the base 1, and a sliding groove 5 on the other side. A bottom shell 3 is placed inside the slot 2, and a top cover 4 is placed inside the sliding groove 5. A positioning mechanism 6 is installed on the slot 2, and an expansion component 7 is installed on the sliding groove 5. Through the coordinated use of the positioning mechanism 6 and the expansion component 7, rapid assembly of the top cover 4 and the bottom shell 3 can be achieved.

[0020] Example 1: As Figure 2 and Figure 3 As shown, the positioning mechanism 6 includes a movable slide groove 602 opened on the slot seat 2 and a cylinder 603 fixedly installed at one end of the base 1. A sliding support 606 is slidably installed in the movable slide groove 602. A limit block 601 is fixedly installed on the upper end of the sliding support 606. A linkage rod 604 is fixedly installed at the output end of the cylinder 603. The sliding support 606 is slidably installed on the linkage rod 604. A spring 605 is sleeved on the linkage rod 604. A limit ring 607 is fixedly installed on the linkage rod 604. A sliding hole is opened in the middle of the sliding support 606. The sliding support 606 is slidably installed on the linkage rod 604 through the sliding hole.

[0021] Specifically, when cylinder 603 extends, it drives linkage rod 604 forward. After linkage rod 604 moves forward, spring 605 immediately returns to its original position. During the return process of spring 605, it pushes sliding foot 606 forward. When sliding foot 606 moves forward, it drives limit block 601 forward, thereby firmly locking the bottom shell 3 in the slot seat 2, facilitating assembly. In addition, when cylinder 603 retracts, limit ring 607 on linkage rod 604 pulls sliding foot 606 back to its original position, causing limit block 601 to loosen from bottom shell 3, making it easy to remove the assembled embedding box.

[0022] Example 2: Figure 2 , Figure 4 and Figure 5 As shown, the expansion assembly 7 includes a lifting seat 702 slidably installed in the slide seat 5 and a wedge block 704 fixedly installed on the linkage rod 604. A wedge expansion block 701 is fixedly installed on the upper surface of the lifting seat 702. Guide rods 703 are fixedly installed on both sides of the lifting seat 702. A tension spring 706 is provided at the lower end of the guide rod 703. A wheel frame 707 is fixedly installed at the middle position of the bottom of the lifting seat 702. A guide wheel 705 is rotatably installed on the wheel frame 707. An inlet and outlet hole is opened on the upper surface of the slide seat 5. The wedge expansion block 701 extends out of the slide seat 5 through the inlet and outlet hole. A sliding groove is opened on the slide seat 5. The guide rod 703 is slidably installed in the slide seat 5 through the sliding groove. One end of the tension spring 706 is fixedly installed at the lower end of the guide rod 703, and the other end of the tension spring 706 is fixedly installed at the bottom of the sliding groove.

[0023] Specifically, after the bottom shell 3 is secured in the slot 2, the wedge block 704 on the linkage rod 604 can continue to move forward via the cylinder 603. As the wedge block 704 moves forward, it forces the guide wheel 705 to move upward. When the guide wheel 705 moves upward, the lifting seat 702 rises synchronously. As the lifting seat 702 rises, the wedge-shaped expansion block 701 extends, expanding the pivot seat on the bottom shell 3. After the pivot seat expands, it can push the top cover 4 towards the bottom shell 3, causing the pivot on the top cover 4 to embed into the pivot seat of the bottom shell 3, thus achieving rapid assembly of the top cover 4 and the bottom shell 3.

[0024] Working principle: In use, first place the bottom shell 3 and top cover 4 into the slot 2 and slide seat 5 respectively. When the cylinder 603 extends, it will drive the linkage rod 604 forward. After the linkage rod 604 moves forward, the spring 605 will return to its original position. During the return process, the spring 605 will push the sliding foot 606 forward. When the sliding foot 606 moves forward, it will drive the limiting block 601 forward, thereby locking the bottom shell 3 in the slot 2 for easy assembly. When the cylinder 603 is retracted, the limiting ring 607 on the linkage rod 604 will pull the sliding foot 606 back to its original position, causing the limiting block 601 to release the bottom shell 3, making it easy to remove the assembled embedding box. After the bottom shell 3 is clamped in the slot seat 2, the wedge block 704 on the linkage rod 604 can be driven by the cylinder 603 to continue moving forward. When the wedge block 704 continues to move forward, it will force the guide wheel 705 to move upward. When the guide wheel 705 moves upward, the lifting seat 702 will move upward in sync with it. When the lifting seat 702 moves upward, the wedge expansion block 701 will extend. When the wedge expansion block 701 extends, it will expand the pivot seat on the bottom shell 3. After the pivot seat expands, it can push the top cover 4 to move towards the bottom shell 3, so that the pivot on the top cover 4 is embedded in the pivot seat on the bottom shell 3, realizing the rapid assembly of the top cover 4 and the bottom shell 3.
