Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of swimming pool filtering equipment, especially swimming pool filtering sand jar. BACKGROUND

[0002] At present, the container for swimming pool filtration is commonly known as swimming pool filtering sand jar, and the jar body is mostly made of glass steel material, and an opening is formed at the upper end of the jar body for adding filter medium (such as quartz sand) or observing the condition in the jar; a jar cover (which can be transparent or opaque) is connected to the opening of the jar body. In order to install and fix the jar cover, a connecting piece for connecting with the jar cover is arranged at the opening. Since both the bonding strength of the connecting piece and the jar body and the sealing performance during use of the sand jar need to be ensured, it is difficult to fix the connecting piece by drilling or other methods. Therefore, at present, the upper part of the glass steel is first prepared, and after solidification, the connecting piece is fixed by the method of polishing first and then laying fiber bonding, and the next process can be used only after the laid fiber is solidified. Before bonding, the joint surface must be polished first to make it rough, and then glue is applied for bonding (for some compact products, even ordinary polishing methods cannot be used, which limits the product structure and size). Polishing of glass steel and wrapping of fiber are time-consuming and labor-intensive, with too much polishing dust, which greatly increases the labor intensity of workers and production cost, and causes a poor working environment. SUMMARY

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a swimming pool filtering sand jar with reasonable structure and lower production cost, which can provide a better working environment for workers during production.

[0004] To solve the above-mentioned technical problems, the utility model adopts the following technical scheme:

[0005] A swimming pool filtering sand jar includes a jar body, a base, a jar cover, and a jar cover connecting piece. A water inlet, a water outlet, and a drain are arranged on the jar body. The lower part of the jar cover connecting piece is connected and fixed to the upper part of the jar body by a pre-embedded piece embedded in the upper part of the jar body during molding of the jar body. The upper part of the jar cover connecting piece is installed by screw thread connection or bolt connection.

[0006] In the improved scheme of the above-mentioned swimming pool filtering sand jar, the pre-embedded piece is a ring embedded in the upper end surface of the jar body during molding of the jar body, and a plurality of bolt holes are arranged in a circumferential direction on the ring; the jar cover connecting piece is a threaded rod with external threads; the external threads of the lower part of the jar cover connecting piece are screwed into the bolt holes of the pre-embedded piece; the jar cover is a transparent cover plate with perforations; and the corresponding perforations of the cover plate are screwed into the upper part of the external threads and then fixed by a nut.

[0007] In the improvement scheme of the above-mentioned swimming pool filtering sand jar, the embedded part is a metal neck ring embedded on the peripheral wall of the upper opening of the jar body when the jar body is formed; the jar cover connecting part is a ring, the lower end of which is fixed into the inner wall of the metal neck ring by adhesive bonding, and the upper end is provided with a threaded ring; the jar cover is a cap with internal threads; the internal threads of the jar cover are screwed and fixed onto the threaded ring of the jar cover connecting part.

[0008] In the improvement scheme of the above-mentioned swimming pool filtering sand jar, the jar body comprises an upper jar body and a lower jar body which are respectively formed and then fixed and connected together by adhesive bonding.

[0009] In the improvement scheme of the above-mentioned swimming pool filtering sand jar, the lower jar body and the base are connected together through a bottom support; the bottom support is embedded in the bottom of the lower jar body when the lower jar body is formed; and the base and the bottom support are fixed and connected by bolts.

[0010] Compared with the prior art, the beneficial effects of the present application are as follows: since the jar cover is connected through an embedded part embedded in the upper part of the jar body when the jar body is formed, the embedded part is used to install the jar cover through adhesive bonding, threaded connection or bolt connection, the threaded connection or bolt connection has a simple structure and can be mass-produced, so that the fixing connecting part does not need to be fixed and connected through polishing and fiber bonding as in the present stage, the structure of the present application is reasonable, the production cost is lower, and the working environment of workers can be better during production.
