[0002] In a diaphragm accumulator, the diaphragm is the key to determining the service life of the accumulator. Currently, the commonly used diaphragms are made of rubber and are generally bowl-shaped. The bowl-shaped diaphragm separates the inner cavity of the accumulator into two chambers, wherein the concave side of the bowl-shaped diaphragm corresponds to the air-filled chamber, and the convex side of the bowl-shaped diaphragm corresponds to the oil-filled chamber. In application, in order to improve the impact resistance of the bottom of the bowl-shaped diaphragm to the oil, a metal reinforcement plate is usually embedded in the bottom of the bowl-shaped diaphragm facing the oil-filled chamber to improve the strength of the bottom of the bowl-shaped diaphragm. Currently, the reinforcement plates used to be embedded in bowl-shaped diaphragms on the market have different structures. Some structures are simple and easy to process, but the bonding with the bowl-shaped diaphragm is poor, and the reinforcement plate is easy to detach from the bowl-shaped diaphragm. Some reinforcement plates have complex structures and better bonding with the bowl-shaped diaphragm, but are difficult to process and have high processing costs. Utility Model Content

The reinforcement plate for accumulator diaphragm includes an anti-slip section 1 and a pressure section 2. The anti-slip section 1 and the pressure section 2 are embedded on the outer side wall of the bottom of the rubber diaphragm 9 along the first direction. The anti-slip section 1 is located inside the side wall of the bottom of the rubber diaphragm 9, and the pressure section 2 is located outside the anti-slip section 1. The outer end face of the pressure section 2 faces the oil-filled chamber and is used to contact with the oil and withstand the impact of the oil. A diameter-reducing section 3 is connected between the anti-slip section 1 and the pressure section 2. The diameter of the diameter-reducing section 3 is smaller than the diameters of the anti-slip section 1 and the pressure section 2, so as to A glue groove 4 is formed between the anti-slip section 1, the reduced diameter section 3 and the pressure-bearing section 2, and the glue groove 4 is used to embed the anti-slip rubber 5. The side wall of the glue groove 4 on the side of the anti-slip section 1 is arranged perpendicular to the first direction so that the anti-slip rubber 5 limits the reverse movement of the anti-slip section 1 along the first direction. The side wall of the glue groove 4 on the side of the pressure-bearing section 2 is inclined from the inside to the outside in the opposite direction of the first direction, so that the width of the cross-section of the glue groove 4 gradually increases from the inside to the outside, so that the thickness of the anti-slip rubber 5 gradually increases from the inside to the outside.

[0027] The present invention provides a reinforcement plate for an accumulator diaphragm. Compared with the prior art, the side wall of the glue groove 4 on the side of the anti-slip section 1 is arranged perpendicular to the first direction, so that the anti-slip rubber 5 embedded in the glue groove 4 blocks the path of the anti-slip section 1 from slipping outward, thereby effectively preventing the anti-slip section 1 from slipping out from the bottom side wall of the rubber diaphragm 9. At the same time, the side wall of the glue groove 4 on the side of the pressure-bearing section 2 is inclined from the inside to the outside in the opposite direction of the first direction, so that the width of the cross-section of the glue groove 4 gradually increases from the inside to the outside, so that the thickness of the anti-slip rubber 5 gradually increases from the inside to the outside, so that the strength and deformation resistance of the anti-slip rubber 5 are increased, and the limiting ability of the anti-slip rubber 5 on the anti-slip section 1 is further enhanced. In addition, the reinforcement plate for the accumulator diaphragm provided by the present invention has a relatively simple structure, is easy to process, and can reduce processing costs.

[0028] In some embodiments, see Figures 1 to 2 The accumulator diaphragm reinforcement plate provided by the present invention is a POM plastic product, wherein the anti-slip section 1, the reduced diameter section 3 and the pressure section 2 are integrally processed and formed. In this embodiment, the anti-slip section 1 and the pressure section 2 are both disc-shaped structures, the anti-slip section 1 and the pressure section 2 are arranged parallel to each other, and the diameter of the anti-slip section 1 is smaller than the diameter of the pressure section 2, the edges of the anti-slip section 1 and the pressure section 2 are chamfered, the reduced diameter section 3 is a cylindrical structure, the reduced diameter section 3 is connected between the anti-slip section 1 and the pressure section 2, the reduced diameter section 3 is coaxial with the anti-slip section 1 and the pressure section 2, and the reduced diameter section 3 is connected to the pressure section 2. Transition arcs are provided between the anti-slip sections 1 and between the reduced diameter section 3 and the anti-slip section 1. In this embodiment, a process hole 6 is provided in the middle of the outer end surface of the pressure-bearing section 2. The process hole 6 is a blind hole. In the production of the rubber diaphragm 9, a pin is provided on the production mold of the rubber diaphragm 9 at a position corresponding to the bottom of the rubber diaphragm 9. Before the rubber diaphragm 9 is vulcanized, the accumulator diaphragm reinforcement plate provided by the present invention is first inserted into the above-mentioned pin through the process hole 6, and then the rubber diaphragm 9 is vulcanized to make the accumulator diaphragm provided by the present invention can be embedded in the bottom of the rubber diaphragm 9.

[0029] In some embodiments, a plurality of oil drain grooves 7 are provided on the outer end surface of the pressure section 2. The plurality of oil drain grooves 7 are radially arranged around the process hole 6. One end of the oil drain groove 7 is connected to the process hole 6, and the other end of the oil drain groove 7 extends toward the edge of the pressure section 2. In actual application, when the oil impacts the pressure section 2, the oil will be rapidly discharged in the circumferential direction of the pressure section 2 through the oil drain groove 7, acting as a force relief for the impact of the oil, thereby reducing the impact force of the oil on the pressure section 2. Optionally, the cross-section of the oil drain groove 7 is arched, and the bottom surface of the oil drain groove 7 with an arched cross-section is a circular arc surface. The circular arc bottom surface has a small blocking effect on the oil, which facilitates the rapid overflow of the oil from the oil drain groove 7.

[0030] In other embodiments, see Figure 4A plurality of reinforcing ribs 8 are provided on the end face of the anti-slip section 1 away from the pressure-bearing section 2. The plurality of reinforcing ribs 8 are arranged crisscrossly. By providing the reinforcing ribs 8, the anti-slip section 1 can still have a high strength after the thickness is reduced, thereby reducing the material used in the anti-slip section 1 and reducing the production cost.

[0031] In other embodiments, see Figure 3 The depth of the oil drain groove 7 decreases from one end of the process hole 6 to the other end. Through the above arrangement, the diffusion speed of the oil in the oil drain groove 7 can be improved, and the unloading effect of the oil drain groove 7 can be improved.
