Description

TECHNICAL FIELD The present invention relates to the technical field of boxes for household goods, more particularly to a box. BACKGROUND In the prior art, CN108928554A—a fresh-keeping box comprises a box body. A box cover is installed at the top end of the box body; an edge is arranged outside the box body; the upper part of the box body is provided with an annular bulge; an annular clamping groove is arranged outside the box cover; an annular silicone pad is arranged inside the annular clamping groove; the box body is matched and connected with the box cover through the annular bulge and the annular clamping groove; an inverted plate is arranged outside the box cover; the inverted plate is buckled on the edge of the box body; a rice placing groove, a soup placing groove and a dish placing groove are arranged inside the box body; foot pads are installed at the bottom end of the box body; storage rooms are arranged inside the foot pads; and one end of the foot pads is provided with a plug matched with the storage rooms. In the present invention, the annular bulge and the annular clamping groove are arranged and the annular silicone pad is arranged inside the annular clamping groove so that the sealing effect of the box body and the box cover is enhanced; and chopsticks and spoons are arranged respectively in the storage rooms of the two foot pads, so as to facilitate the carrying of the chopsticks and the spoons. However, in the above fresh-keeping box, because dirt may be attached to the surface of the annular silicone pad with a sealing effect after long-term use, and because the annular silicone pad is entirely embedded in the annular clamping groove on the box cover when the annular silicone pad needs to be taken out for washing or disinfection, it is difficult to take out the annular silicone pad from the annular clamping groove and is inconvenient to use. Moreover, the annular silicone pad in the fresh-keeping box can only achieve one seal, and the sealing effect is poor. Therefore, the problem to be urgently solved by those skilled in the art is how to provide a box which is easy for separating a sealing ring from the box cover, convenient for disassembly and assembly of the sealing ring and good in sealing performance. SUMMARY In view of this, the present invention provides a box which is easy for separating a sealing ring from a box cover, convenient for disassembly and assembly of the sealing ring and good in sealing performance. To achieve the above purpose, the present invention adopts the following technical solution: A box comprises: a box body, wherein the top end of the box body is open;a box cover, wherein the box cover is covered at an opening of the box body, a limiting cylinder is formed on the bottom end of the box cover near an outer edge, and the bottom end of the box cover is provided with an annular clamping groove located at the outer side of the limiting cylinder;an elastic sealing ring which comprises:a top sealing ring, wherein the top sealing ring is crimped between the open end of the box body and the bottom end surface of the box cover, an inserting flange is integrally formed at the top end of the top sealing ring, and the inserting flange is clamped in the annular clamping groove;a middle sealing cylinder, wherein the outer wall of a cylinder port of the top end of the middle sealing cylinder is integrally connected with a ring port of the top sealing ring, and the middle sealing cylinder is sleeved on the outer cylinder wall of the limiting cylinder;a bottom sealing ring, wherein a ring port of the bottom sealing ring is integrally formed and connected with the outer wall of the cylinder port of the bottom end of the middle sealing cylinder, and the outer edge of the bottom sealing ring is in compression sealing contact with the inner wall of the box body. It can be known from the above technical solution that compared with the prior art, the present invention discloses and provides a box. When the box cover is covered on the box body, the bottom sealing ring and the inner wall of the box body are in compression sealing contact as a first seal, and the top sealing ring is pressed between the box cover and the box body and serves as a second seal. Therefore, the elastic sealing ring of the box body can play a role of double seals to improve the sealing performance of the box body. Moreover, the limiting cylinder plays a supporting and limiting role on the middle sealing cylinder. When the box cover is buckled, it is convenient for the bottom sealing ring to exert extrusion force on the inner wall direction of the box body, so as to achieve tight contact sealing with the inner wall of the box body and ensure the sealing effect. In addition, the elastic sealing ring is exposed outside of the box cover, which is easy to disassemble and assemble the elastic sealing ring and the box cover, so as to facilitate the washing and disinfection of the elastic sealing ring, and the elas
