The connection mode of the connecting component 2 is simplified, and the tank body is stably fixed in the frame body 1 through the cooperation of the annular supporting cylinder 21 and the limiting cushion block 22, so that the stable connection between the frame body 1 and the tank body is realized.
Because the annular supporting cylinder 21 is matched with the limit cushion block 22, the connection mode between the frame body 1 and the tank body is expanded to the surface from the original point, and only the limit cushion block 22 is fixedly connected with the frame body 1, so that the connection relation of the connecting assembly 2 is relatively simple. The circular supporting cylinder 21 with the circular arc-shaped section ensures that the transition of the joint with the tank body is gentle, greatly reduces the stress concentration, and simultaneously increases the bending deformation resistance of the structure.
In one embodiment, the circular arc length of the cross section of the annular supporting cylinder 21 is smaller than one fourth of the virtual circumference where the circular arc is located, so that the annular supporting cylinder 21 can be well matched with the edge of the end face of the tank body, the minimum inner diameter of the annular supporting cylinder 21 is larger than the diameter of the tank body of the tank container, and the maximum inner diameter of the annular supporting cylinder 21 is larger than the diameter of the tank body of the tank container, so that the annular supporting cylinder 21 can be effectively wrapped at the end part of the tank body, and the movement of the tank body in the frame body 1 is limited.
Meanwhile, the inner wall of the circular arc structure is also beneficial to the rapid discharge of the foreign matters from the space between the annular supporting cylinder 21 and the tank body.
The circular support cylinder 21 and the cylinder wall of the position where the limiting cushion block 22 is matched are uniformly provided with a plurality of clamping grooves 23, and the clamping grooves 23 are matched with the clamping blocks 25, so that the circular support cylinder 21 and the limiting cushion block 22 are better connected together, and meanwhile, the rotation of the circular support cylinder 21 can be limited, and the relative position of the tank body and the frame body 1 is stable.
The limiting cushion block 22 is detachably and fixedly connected with the inner side of the end part of the frame body 1, the end part of the limiting cushion block 22, which is far away from the frame body 1, is arc-shaped, and a virtual circle where the arc is located is concentric with the annular supporting cylinder 21, the limiting cushion block 22 is fixedly connected with the inner side of the end part of the frame body 1 through bolts, and the end part of the arc-shaped structure can be matched with the annular supporting cylinder 21 better.
The limit cushion block 22 is provided with an arc groove 24 corresponding to one side of the annular supporting cylinder 21, the inner wall of the arc groove 24 is in clearance fit with the outer wall of the annular supporting cylinder 21, and the arc groove 24 improves the contact area between the limit cushion block 22 and the annular supporting cylinder 21, so that the assembly and the connection stability are realized.
The inner wall of the arc-shaped groove 24 is uniformly provided with a plurality of clamping blocks 25, the clamping blocks 25 are uniformly distributed on a virtual circle formed by the circle center of the annular supporting cylinder 21, the clamping blocks 25 are matched with the corresponding clamping grooves 23 in a clamping manner, and the clamping blocks 25 are matched with the clamping grooves 23 in a clamping manner, so that the matched clamping blocks 25 do not influence the flatness of the inner wall of the annular supporting cylinder 21, and the length of the clamping blocks 25 is smaller than the depth of the clamping grooves 23.
In another embodiment, the number of the limit pads 22 is four, and the limit pads 22 are all located at the middle of the frame edges at two ends of the frame body 1, so that the frame edges at two ends of the frame body 1 are uniformly stressed.
