Glass fiber reinforced plastic container

Abstract

The glass fiber reinforced plastic container comprises an upper cylinder body, a lower cylinder body and a seat body, wherein the upper cylinder body and the lower cylinder body are formed by glass fiber reinforced plastic; an annular sleeving groove defined by an inner ring and an outer ring is formed in the peripheral wall of the lower end of the upper cylinder body; a sleeving ring capable of being sleeved into the sleeving groove is arranged at the upper end of the lower cylinder body; a plurality of glue guide holes are formed in the peripheral wall of the sleeving ring at intervals; when the upper cylinder body and the lower cylinder body are bonded, after the upper cylinder body is inverted, the sleeving groove is filled with mucilage glue, and after the lower cylinder body is inverted, the sleeving ring is stably and downwards sleeved into the sleeving groove, so that a grinding procedure which wastes time and labor and is used in a severe working environment is omitted; the production cost is greatly reduced, the working environment of workers is improved, and the labor intensity of the workers is reduced; in addition, by means of the flow guide effect of the glue flow guide holes, the situation that glue overflows is greatly reduced, glue joint between the upper cylinder body and the lower cylinder body can be more uniform and firmer, and therefore combination of the water tank is more reasonable.

Description

Technical Field

[0001] This utility model relates to a swimming pool filtration device, and more particularly to a fiberglass container for swimming pool filtration. Background Technology

[0002] Currently, containers used for pool filtration are commonly known as sand filters. They are mostly made of fiberglass and mainly consist of an upper tank and a lower tank. These are manufactured using molds and then glued together at the joints. Because the surface of fiberglass is smooth, the joint surfaces must be roughened by sanding before gluing can be applied. We know that fiberglass is a very hard material, making grinding time-consuming and labor-intensive, producing excessive dust and creating a harsh working environment. Furthermore, because the upper and lower cylinders are hemispherical or U-shaped shells, workers must bend over to reach the inner surface, significantly increasing their workload. Additionally, the small opening at the top of the cylinder necessitates reaching through it to lay fibers and apply resin at the connection point, a very difficult process (if the upper part is slightly longer, the connection point may be inaccessible by hand), thus limiting the product's structural design. Therefore, the manufacturing of fiberglass sand filter containers is currently challenging, resulting in high production costs and increased labor intensity, which is detrimental to worker health. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fiberglass container with a more reasonable combination and lower production cost, which helps to improve the working environment of workers and reduce the labor intensity of workers.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0005] A fiberglass container includes an upper cylinder and a lower cylinder formed of fiberglass, and a base supporting the bottom of the lower cylinder. The lower end of the upper cylinder has an annular groove formed by an inner ring and an outer ring on its peripheral wall. The upper end of the lower cylinder has an insert ring that can be fitted into the groove. The insert ring has a plurality of glue guide holes spaced apart on its peripheral wall. When bonding the upper and lower cylinders, the upper cylinder is inverted and glue is filled into the groove. Then the lower cylinder is inverted and the insert ring is smoothly fitted into the groove.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: An annular groove formed by an inner and outer ring is provided at the lower end of the upper cylinder body; an insert ring that can fit into the groove is provided at the upper end of the lower cylinder body; multiple glue guide holes are spaced apart on the peripheral wall of the insert ring; when bonding the upper and lower cylinder bodies, after inverting the upper cylinder body, glue is filled into the groove, and then the lower cylinder body is inverted so that the insert ring is smoothly inserted into the groove. After the glue cures, the upper and lower cylinder bodies are firmly bonded together, thus saving time. The laborious and harsh grinding process significantly reduces production costs, improves the working environment for workers, and reduces their labor intensity. Furthermore, because the socket groove is divided into inner and outer layers by the insert ring, during the insertion process, a significant amount of adhesive located on the outer or inner side of the insert ring flows from the socket groove of that layer through the adhesive guide hole into the socket groove of the other layer. This greatly reduces adhesive overflow and ensures a more uniform and reliable adhesive bond between the upper and lower cylinders. Therefore, the design of this invention is more rational.

[0007] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: Attached Figure Description

[0011] Figure 4 yes Figure 3 A magnified view of part I. Detailed Implementation

[0012] This utility model is a fiberglass container, such as Figures 1 to 4As shown, it includes an upper cylinder 1 and a lower cylinder 2 made of fiberglass, and a base 3 supporting the bottom of the lower cylinder 2. These are consistent with the fiberglass containers of current sand filter tanks. The difference is that: the lower end of the upper cylinder 1 has an annular fitting groove 13 formed by an inner ring 11 and an outer ring 12, which is integrally formed when the upper cylinder is formed; the upper end of the lower cylinder 2 has a fitting ring 21 that can be fitted into the fitting groove 13; the fitting ring 21 has a groove on its peripheral wall. Multiple adhesive guide holes 211 are provided at intervals. When bonding the upper cylinder 1 and the lower cylinder 2, the upper cylinder 1 is inverted and adhesive is filled into the fitting groove 13. Then, the lower cylinder 2 is inverted and the fitting ring 21 is smoothly inserted into the fitting groove 13. After the adhesive cures, the upper and lower cylinders are firmly bonded together. This eliminates the time-consuming, labor-intensive, and harsh grinding process, thereby greatly reducing production costs, improving the working environment for workers, and reducing the labor intensity of workers. In addition, since the fitting groove 13 is divided into inner and outer layers by the fitting ring 21, during the insertion process, a large amount of adhesive located on the outer or inner side of the fitting ring 21 flows from the fitting groove of that layer through the adhesive guide holes 211 into the fitting groove of the other layer. This greatly reduces adhesive overflow and makes the adhesive bonding between the upper and lower cylinders more uniform and reliable. Therefore, the combination of this utility model is more reasonable.
