[0002] The disc spring, also known as the Belleville spring washer, is in the shape of a conical disc. It can be used alone or in series or parallel. It bears static or dynamic loads acting axially at the upper inner edge and lower outer edge. After being compressed, it deforms until it is flattened to store energy in the form of live load. When necessary, it automatically converts into the additional compression load required for sealing to reduce the continuous requirement for tightening in the use of gaskets and packings.

[0003] However, in the process of using the existing assembled disc spring, the installation is relatively inconvenient and it is not convenient to be spliced, resulting in poor use effect. Summary of the Invention

[0004] The purpose of the utility model is to solve the problem that in the process of using the existing assembled disc spring, the installation is relatively inconvenient and it is not convenient to be spliced, and to provide a disc spring structure.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A disc spring structure includes two first C-shaped plates and two second C-shaped plates. Reinforcing mechanisms are arranged on the inner surfaces of the first C-shaped plates and the second C-shaped plates. A first fixing block is fixedly connected to the outer surface of the first C-shaped plate, and a second fixing block is fixedly connected to the outer surface of the second C-shaped plate. A slot is opened at the top of the second fixing block, and a plug board is fixedly connected to the bottom of the first fixing block. A limiting slot is opened on one side of the plug board. An empty slot is opened inside the second fixing block. A screw rod is rotatably connected inside the empty slot. A limiting block is sleeved on the outer surface of the screw rod. One side of the limiting block movably penetrates through the empty slot and extends into the limiting slot. A sliding slot is opened on the inner side of the empty slot. A sliding plate is slidably connected inside the sliding slot. The top of the sliding plate is fixedly connected to the limiting block.

[0006] Preferably, the reinforcing mechanism includes a placement groove opened on the inner surfaces of the first C-shaped plate and the second C-shaped plate, and a telescopic rod is fixedly connected inside the placement groove.

[0007] Preferably, a compression spring is sleeved on the outer surface of the telescopic rod, and a pressing plate is fixedly connected to one end of the telescopic rod.

[0008] Preferably, clamping grooves are opened on the outer surfaces of one of the first C-shaped plates and one of the second C-shaped plates, and clamping blocks are fixedly connected to the outer surfaces of the other first C-shaped plate and the other second C-shaped plate.

[0009] Preferably, positioning grooves are formed on the outer surfaces of one of the first C-shaped plates and one of the second C-shaped plates, and positioning blocks are fixedly connected to the outer surfaces of the other first C-shaped plate and the other second C-shaped plate.

[0010] Preferably, the card slot matches the card block, and the positioning block matches the positioning groove.

[0011] Preferably, the smooth end of the screw rod movably penetrates through the empty groove and extends to the outside of the second fixing block, and a rotating cap is fixedly installed at the smooth end of the screw rod.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, by inserting the insertion plate at the bottom of the first C-shaped plate into the insertion slot, and then rotating the screw rod. Since the sliding plate limits the position of the limiting block, when the screw rod rotates, it drives the limiting block to move. The limiting block drives the sliding plate to slide in the sliding groove, so that the limiting block moves into the limiting groove, thereby limiting and fixing the insertion plate, facilitating the installation between the first C-shaped plate and the second C-shaped plate, and enabling them to be butted into a dish shape with convenient operation. When disassembly is required, by reversing the screw rod, the screw rod drives the limiting block to move and separate from the limiting groove, and then the insertion plate at the bottom of the first C-shaped plate can be pulled out from the insertion slot, facilitating the disassembly between the first C-shaped plate and the second C-shaped plate.

[0014] 2. In the present utility model, through the setting of the strengthening mechanism, when the disc spring is working and deforming, the surfaces of the pressing plates inside it are mutually attached. Then, as the disc spring continues to deform, it applies an elastic force to the compression spring through the pressing plate, enabling it to bear the external force, thereby increasing the bearing capacity of the present utility model. Further, by inserting the card block on another first C-shaped plate or another second C-shaped plate into the card slot on one of the first C-shaped plates or one of the second C-shaped plates, the two first C-shaped plates or the two second C-shaped blocks are clamped and installed together, facilitating the installation of the two first C-shaped plates or the two second C-shaped plates.

[0022] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further explains this utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figure 1 - Figure 6 shown, this utility model provides a disc spring structure, including two first C-shaped plates 1 and two second C-shaped plates 2. Reinforcing mechanisms 3 are arranged on the inner surfaces of the first C-shaped plates 1 and the second C-shaped plates 2. A first fixing block 4 is fixedly connected to the outer surface of the first C-shaped plate 1, a second fixing block 5 is fixedly connected to the outer surface of the second C-shaped plate 2. A slot 6 is opened at the top of the second fixing block 5, an insertion plate 7 is fixedly connected to the bottom of the first fixing block 4, a limiting groove 8 is opened on one side of the insertion plate 7, an empty groove 9 is opened inside the second fixing block 5, a screw 10 is rotatably connected inside the empty groove 9, a limiting block 11 is sleeved on the outer surface of the screw 10, one side of the limiting block 11 movably penetrates through the empty groove 9 and extends into the limiting groove 8, a sliding groove 12 is opened on the inner side of the empty groove 9, a sliding plate 13 is slidably connected inside the sliding groove 12, and the top of the sliding plate 13 is fixedly connected to the limiting block 11.

[0025] The effect achieved by the entire Embodiment 1 is that by inserting the insertion plate 7 at the bottom of the first C-shaped plate 1 into the slot 6, and then rotating the screw 10, since the sliding plate 13 limits the limiting block 11, when the screw 10 rotates, it drives the limiting block 11 to move. The limiting block 11 drives the sliding plate 13 to slide in the sliding groove 12, so that the limiting block 11 moves into the limiting groove 8, thereby limiting and fixing the insertion plate 7, facilitating the installation between the first C-shaped plate 1 and the second C-shaped plate 2, and capable of forming a disc spring, with convenient operation. When disassembly is required, by reversing the screw 10, the screw 10 drives the limiting block 11 to move and separate from the limiting groove 8, and then the insertion plate 7 at the bottom of the first C-shaped plate 1 can be pulled out of the slot 6, facilitating the disassembly between the first C-shaped plate 1 and the second C-shaped plate 2.

[0026] Embodiment 2: As Figure 1 - Figure 6 shown, the strengthening mechanism 3 includes a placement groove 301 which is opened on the inner surfaces of the first C-shaped plate 1 and the second C-shaped plate 2. A telescopic rod 302 is fixedly connected in the placement groove 301. A compression spring 303 is sleeved on the outer surface of the telescopic rod 302. One end of the telescopic rod 302 is fixedly connected with a pressing plate 304. Slots 14 are opened on the outer surfaces of one of the first C-shaped plates 1 and one of the second C-shaped plates 2, and clamping blocks 15 are fixedly connected to the outer surfaces of the other first C-shaped plate 1 and the other second C-shaped plate 2. Positioning grooves 16 are opened on the outer surfaces of one of the first C-shaped plates 1 and one of the second C-shaped plates 2, and positioning blocks 17 are fixedly connected to the outer surfaces of the other first C-shaped plate 1 and the other second C-shaped plate 2. The slots 14 match the clamping blocks 15, and the positioning blocks 17 match the positioning grooves 16. The smooth end of the screw 10 movably penetrates through the empty groove 9 and extends to the outside of the second fixing block 5, and a rotating cap 18 is fixedly installed on the smooth end of the screw 10.

[0027] The effect achieved by the entire Embodiment 2 is that by providing the strengthening mechanism 3, when the disc spring is working and deforming, the surfaces of the pressing plates 304 inside it are in mutual contact. Then, as the disc spring continues to deform, the compression spring 303 is applied with an elastic force through the pressing plate 304, enabling it to bear the external force, thereby increasing the bearing capacity of the present utility model. By inserting the clamping block 15 on the other first C-shaped plate 1 or the other second C-shaped plate 2 into the slot 14 on one of the first C-shaped plates 1 or one of the second C-shaped plates 2, the two first C-shaped plates 1 or the two second C-shaped plates 2 are clamped and installed together, facilitating the installation of the two first C-shaped plates 1 or the two second C-shaped plates 2. When the two first C-shaped plates 1 or the two second C-shaped plates 2 are spliced and installed, the positioning block 17 is inserted into the positioning groove 16. By setting the cross-section of the positioning block 17 to be T-shaped, the separation between the two can be prevented, improving the stability of the assembly. By providing the rotating cap 18, it is convenient to rotate the screw 10, increasing the convenience.

[0028] Working principle: When in use, the clamping blocks 15 on another first C-shaped plate 1 and another second C-shaped plate 2 are inserted into the clamping slots 14 on one of the first C-shaped plates 1 and one of the second C-shaped plates 2, so that the two first C-shaped plates 1 and the two second C-shaped blocks 2 are clamped and installed together. Subsequently, the insertion plates 7 at the bottoms of the two first C-shaped plates 1 are inserted into the insertion slots 6 at the tops of the two second C-shaped plates 2. Then, the screw rod 10 is rotated. Since the sliding plate 13 limits the position of the limiting block 11, when the screw rod 10 rotates, it drives the limiting block 11 to move. The limiting block 11 drives the sliding plate 13 to slide in the sliding groove 12, so that the limiting block 11 moves into the limiting groove 8, thereby limiting and fixing the insertion plate 7, completing the splicing between the first C-shaped plate 1 and the second C-shaped plate 2, and thus a disc spring can be formed. The operation is convenient. When the disc spring is working and undergoes deformation, the surfaces of the pressing plates 304 inside it are in mutual contact. Then, the disc spring continues to deform, so that an elastic force is applied to the compression spring 303 through the pressing plates 304, enabling it to bear the external force, thereby increasing the bearing capacity of the present invention.

[0029] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
