Description

Technical Field

[0001] The utility model relates to the technical field of washers, in particular to a special-shaped plastic washer. Background Art

[0002] A washer refers to a part placed between the connected part and the nut. It is generally a flat metal ring used to protect the surface of the connected part from being scratched by the nut and to disperse the pressure of the nut on the connected part. Compared with metal washers, plastic washers have excellent insulation, corrosion resistance, heat insulation and non-magnetic properties, and are light in weight. They are widely used in various fields such as semiconductors, automobiles, aerospace industries and interior decoration.

[0003] Various plastic washers are needed in the assembly process of various equipment, but standard parts of washers cannot be used in some positions and need to be specially customized. Plastic washers are generally made by injection molding. Individually customized plastic washers need to make special molds first, which increases production costs. For this reason, we propose a special-shaped plastic washer. Utility Model Content

[0009] Furthermore, a flat groove is provided at the intersection of the two tenons 1 of the positioning block and at the intersection of the two tenons 2 of the transition block to facilitate injection molding.

[0010] Furthermore, it also includes a seal, wherein a mortise groove three is provided in the middle of the seal, and the seal is respectively connected to the inside of the tenon one and the tenon two at the edge through the mortise groove three to prevent the outermost tenon one and the tenon groove two from being damaged.

[0011] Furthermore, it also includes a blocking block, wherein the left side and the front side of the blocking block are provided with tenons three, and the blocking block is clamped between two tenons three whose edges are perpendicular to each other through the tenons three to prevent the sharp edges from scratching the workers.

[0012] Furthermore, the connection positions between the positioning block and the adjacent transition block, the connection positions between the positioning block and the adjacent seal, the connection positions between the transition block and the adjacent seal, and the connection positions between the blocking block and the adjacent seal are all bonded with AB glue to avoid falling apart.

[0013] Furthermore, the positioning blocks, transition blocks and blocking blocks are all high-density polyethylene blocks, and the sealing strips are high-density polyethylene strips, which have good mechanical properties and low prices.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The workers assemble the positioning block and the transition block according to the position of the axis or the mounting hole of the component at the installation position of the special-shaped plastic gasket.
