[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.
[0015] like Figure 1 to Figure 2 As shown, it is a schematic diagram of the structure of a top sealing structure of a container provided by the utility model. The top sealing structure of the container includes a box body 1, a box body opening 2 arranged at the top of the box body 1, a top plate 3 arranged on one side of the box body 1, and a sealing unit 10 arranged at the edge of the box body opening 2. It can be understood that the top sealing structure of the container should also include some other functional components, such as installation components, fastening components, etc., which are prior arts known to those skilled in the art and will not be described one by one here.
[0016] The box body 1, the box body opening 2, the top plate 3 and the connection methods among the box body 1, the box body opening 2 and the top plate 3 are all prior arts well known to those skilled in the art and will not be elaborated herein.
[0017] The sealing unit 10 includes a box sealing assembly 11 arranged on the edge of the box opening 2, a top plate sealing assembly 12 arranged on the side of the top plate 3 facing the box 1, and a plurality of corner pieces 13 respectively arranged at the top corners of the box opening 2.
[0018] The box body sealing assembly 11 includes an upper beam square tube 111 arranged on the box body 1, a top edge angle steel 112 fixedly connected to the upper beam square tube 111, and a mechanical sealing angle steel 113 fixed to the top edge angle steel.
[0019] The upper square tube 111 can be fixedly arranged at one end of the box body 1 close to the top plate 3 by welding or the like. The upper square tube 111 is used to strengthen the lateral strength of the box body 1, thereby preventing the box body 1 from deforming during use and affecting the connection sealing between the box body 1 and the top plate 3.
[0020] The top edge angle steel 112 is an L-shaped steel, that is, the overall outer contour of the top edge angle steel 112 is an L-shaped structure. One side of the L-shaped top edge angle steel 112 is fixedly connected to the upper beam square tube 111, and the other side is used to be inserted into the top plate sealing assembly 12, thereby forming a sealing state with the top plate sealing assembly 12.
[0021] The outer contour of the mechanical sealing angle steel 113 is an L-shape rotated 90 degrees clockwise, one side of the L-shape is fixedly connected to the top edge angle steel 112, and the other side is accommodated in the top plate sealing assembly 12, and forms a further seal for the container with the top plate sealing assembly 12. The height of the mechanical sealing angle steel 113 is less than the height of the top edge angle steel 112, so that a stepped clearance space is formed at the connection between the mechanical sealing angle steel 113 and the top edge angle steel 112, so as to facilitate the connection between the mechanical sealing angle steel 113, the top edge angle steel 112 and the sealing strip 122 described below.
[0022] The top plate sealing assembly 12 includes a top plate frame channel steel 121 disposed on the side of the top plate 3 facing the box body 1 , and a sealing strip 122 accommodated in the top plate frame channel steel 121 .
[0023] The top plate frame channel steel 121 is fixedly arranged on the top plate 3 along the four sides of the top plate 3. The top plate frame channel steel 121 includes a channel steel body 1211 and a sealing strip mounting groove 1212 arranged on the side of the channel steel body 1211 facing the box sealing assembly 11. One side of the main channel steel 1211 can be fixedly connected to the top plate 3 by welding or the like. The sealing strip mounting groove 1212 is arranged on the side of the channel steel body 1211 opposite to the top plate 3 to accommodate the sealing strip 122. In the cross section perpendicular to the extension direction of the top plate frame channel steel 121, the length of the mechanical sealing angle steel 113 is less than the length of the sealing strip mounting groove 1212, so that when the box sealing assembly 11 is connected to the top plate sealing assembly 12, the mechanical sealing angle steel 113 can be accommodated in the sealing strip mounting groove 1212.
[0024] The sealing strip 122 can be made of a material such as synthetic rubber that has good sealing properties and is easy to replace. The outer contour of the sealing strip 122 is matched with the inner contour of the sealing strip installation groove 1212, and the sealing strip 122 is fitted in the sealing strip installation groove 1212. The depth of the sealing strip installation groove 1212 is greater than the thickness of the sealing strip 122, so that the sealing strip installation groove 1212 can accommodate the sealing strip 122 while also protecting the box sealing assembly 11.
[0025] When the top plate 3 is installed on the box body 1, one end of the top edge angle steel 112 abuts against the sealing strip 122, and one side wall of the mechanical sealing edge angle steel 113 fits the top and bottom of the sealing strip 122. Therefore, a double sealing structure is formed between the box body sealing assembly 11 and the top plate sealing assembly 12 through the top edge angle steel 112 and the mechanical sealing edge angle steel 113 and the sealing strip 122, so that when the top edge angle steel 112 is deformed by external force, the sealing structure between the box body sealing assembly 11 and the top plate sealing assembly 12 is still reliable. Preferably, when the box sealing assembly 11 is connected with the top plate sealing assembly 12, the end of the top edge angle steel 112 facing the top plate sealing assembly 12 and the side wall of the mechanical sealing angle steel 113 facing the top plate sealing assembly 12 are both accommodated in the sealing strip mounting groove 1212 to enhance the connection stability between the box sealing assembly and the top plate sealing assembly.
[0026] Preferably, when the top plate 3 is mounted on the box body 1, the corner piece 13 may be further fixed at the top corner of the box body opening 2. The corner piece 13 itself is a prior art known to those skilled in the art and will not be described in detail here.
[0027] Compared with the prior art, the top sealing structure of a container provided by the utility model includes a box body 1, a box body opening 2 arranged at the top of the box body 1, a top plate 3 arranged on the opening 2, and a sealing unit 10 arranged on the edge of the box body opening 2. The sealing unit 10 includes a box body sealing assembly 11 arranged at the edge of the box body opening 2, and a top plate sealing assembly 12 arranged on the side of the top plate 3 facing the box body 1. The box body sealing assembly 11 includes an upper beam square tube 111 arranged on the edge of the box body opening 2, a top edge angle steel 112 fixedly connected to the upper beam square tube 111, and a mechanical sealing angle steel 113 fixedly connected to the top edge angle steel 112. The outer contour of the top edge angle steel 112 is L-shaped, and the outer contour of the mechanical sealing angle steel 113 is L-shaped rotated 90 degrees clockwise. The top plate sealing assembly 12 includes a top plate frame channel steel 121 arranged on the side of the top plate 3 facing the box body 1, and a sealing strip 122 accommodated in the top plate frame channel 121. When the top plate 3 is installed on the box body 1, the end of the top edge angle steel 112 facing the top plate sealing assembly 12 and the side wall of the mechanical sealing angle steel 113 facing the top plate sealing assembly 12 are both in contact with the sealing strip 122, so that the top edge angle steel 112 and the mechanical sealing angle steel 113 form a double sealing structure with the sealing strip 122 respectively. So that when the top edge angle steel 112 is deformed by external force, the sealing structure between the box body sealing assembly 11 and the top plate sealing assembly 12 is still reliable.
