Description
Technical Field
[0001] The utility model relates to the technical field of motor accessories, in particular to a high-performance waterproof cover injection molding part. Background Art
[0002] High-performance waterproof covers are widely used in various types of motors, whether in household appliances, industrial equipment or transportation, etc., they are inseparable from the support and protection of the motor end cover, an important component. The motor end cover is usually made of metal and has sufficient strength and rigidity to withstand the vibration and impact generated by the motor during operation.
[0003] However, although the traditional motor end cover can meet people's needs during use, there are still some problems. When the traditional motor end cover involves a shaft with different inner diameters, the center sleeve cannot be changed, which makes the motor end cover unable to adapt to the shafts with different thicknesses, so the applicability is low. In terms of waterproofing, simple rubber gaskets are mostly used to achieve sealing, and the sealing structure is relatively simple. Therefore, a high-performance waterproof cover injection molding is needed to solve the above problems. Utility Model Content
[0004] The utility model aims to provide a high-performance waterproof cover injection molding part, which is used to solve the defects that the inner diameter of the existing central shaft sleeve cannot be adjusted to adapt to rotating shafts of different specifications and the sealing performance is single.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-performance waterproof cover injection molding, including a cover plate and a fixing block; the outer side of the cover plate is evenly provided with fixing blocks, a sealing structure is provided at the edge of one side of the cover plate, a sleeve assembly is provided at the center position of the cover plate, and bone tendons are evenly fixed on the outer wall of the sleeve assembly; the sleeve assembly includes a central sleeve, a screw, a fixing plate, a combined ring and a groove, the outer periphery of the central sleeve is connected to the cover plate, a groove is provided inside the central sleeve, screws are provided on both sides of the top of the central sleeve, a combined ring is provided at the center position of the central sleeve, and fixing plates are provided on both sides of the combined ring; the sealing structure includes a first protrusion, a second protrusion and a sealing sleeve, the first protrusion is provided at the edge of one side, the second protrusion is integrally formed on the cover plate on one side of the first protrusion, and the outer sides of the first protrusion and the second protrusion are both sleeved with sealing sleeves.
[0006] Preferably, four groups of the fixing blocks are provided, and the four groups of the fixing blocks are arranged at equal intervals on the outer circumference of the cover plate.
[0007] Preferably, a fixing plate cooperating with the groove is provided inside the central sleeve, and a rotatable connection is formed between the central sleeve and the combined ferrule.
[0008] Preferably, reinforcing plates are welded on both sides of the ribs away from one end of the shaft sleeve assembly, and four groups of ribs are provided, and the angles between adjacent ribs are °.
[0009] Preferably, the reinforcing plate and the bone tendons form a triangle.
[0010] Preferably, the inner diameter of the central sleeve is larger than the outer diameter of the combined ring, and a movable connection is formed between the central sleeve and the combined ring.
[0011] The utility model provides a high-performance waterproof cover injection molded part, which has the advantages of:
[0012] By using the center sleeve and screws together, the fixing plate can be inserted into the groove inside the center sleeve, and then the fixing plate is rotated to one position and fixed in position with screws, thereby changing the inner diameter of the center sleeve to accommodate motor shafts of different specifications, making it more suitable for use.
[0013] By setting the first protrusion and the second protrusion to different lengths, the structural sealing is increased. When the cover is connected to the motor through the first protrusion and the second protrusion, even if water flows in, the water will bypass the first protrusion and then the second protrusion. The outer sides of the first protrusion and the second protrusion are both provided with sealing sleeves, and further physical sealing is performed to achieve double-layer sealing. The surface is coated with a paint layer to prevent rust, thereby achieving a better sealing effect.
[0014] By using a reinforcing plate, a triangular support can be provided on both sides of the rib. Since the triangle is stable, the connection between the cover plate and the sleeve assembly can be reinforced by the reinforcing plate, so that the connection between the two ends of the rib is not prone to cracking when subjected to the vibration and impact generated by the motor during operation for a long time, thereby completing the reinforcement work.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The sleeve assembly 5 includes a central sleeve 501, a screw 502, a fixing plate 503, a combined ring 504 and a groove 505. The periphery of the central sleeve 501 is connected to the cover plate 1. The central sleeve 501 is provided with a groove 505. Screws 502 are provided on both sides of the top of the central sleeve 501. A combined ring 504 is provided at the center of the central sleeve 501. Fixing plates 503 are provided on both sides of the combined ring 504. The central sleeve 501 is provided with a fixing plate 503 that cooperates with the groove 505. A rotatable connection is formed between the central sleeve 501 and the combined ring 504. The inner diameter of the central sleeve 501 is larger than the outer diameter of the combined ring 504. A movable connection is formed between the central sleeve 501 and the combined ring 504.
[0026] Specifically, in this embodiment: when encountering a rotating shaft with a different inner diameter, the center sleeve 501 and the screw 502 are matched in size so that the fixing plate 503 can be inserted into the groove 505 inside the center sleeve 501, and then when the fixing plate 503 is rotated to a position, a screw 502 that matches it is set on the top of the center sleeve 501. When the position of the fixing plate 503 is turned to the fixed point, the screw 502 can be used to pass through the center sleeve 501 and enter into the small hole on the surface of the fixing plate 503, and then fix its position. This achieves that when facing rotating shafts with different inner diameters, the rotating shaft can be quickly disassembled and replaced without replacing the end cover.
