Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

Example 1:

as shown in fig. 1-4, the bottom end of the auxiliary protection device for the on-line treatment before the coating of the container is a rectangular frame-shaped chassis 1 formed by welding a plurality of sections of I-shaped rails, and the lower ends of the I-shaped rails are buried in the ground; four top corners at the upper part of the chassis 1 are in threaded connection with 4 groups of supports 2 through threaded holes 201, 4 groups of support rods 3 are arranged above the 4 groups of supports 2, and the support rods 3 are square tubes; the support 2 is in an axisymmetrical shape around the support 2, two groups of vertical plates 202 which are parallel to each other are arranged on the support 2, semi-annular key grooves 204 and semi-annular holes 205 are respectively and oppositely arranged on the two groups of vertical plates 202 which are parallel to each other, the holes 205 are positioned below the key grooves 204, square grooves 203 are arranged on the upper surface of the support 2, the square grooves 203 are positioned between the two groups of vertical plates 202 which are parallel to each other, and the square grooves 203 are in clearance fit with the profile of the bottom section of the support rod 3; two groups of coaxial key blocks 301 are arranged on two circumferentially opposite surfaces of the support rod 3, the cross sections of the key blocks 301 are rectangular, and the key blocks 301 are connected with the key grooves 204 in a sliding fit manner; two sets of mutually opposite elongated slots 302 are arranged on the wall layer of the support rod 3 below the key block 301; a pin 4 is arranged in the hole 205, and the pin 4 penetrates through the elongated slot 302.

Preferably, the threaded holes 201 are four groups and evenly distributed on four top corners of the support 2.

Preferably, the sum of the length of the key groove 204 and the depth of the square groove 203 is smaller than the length of the long groove 302.

Example 2:

the difference between the embodiment 2 and the embodiment 1 is that the number of the supports is 6, and the supports are respectively arranged at four top corners of the chassis 1 and the middle parts of two long sides of the chassis 1; the bottom contour of the support rod 3 is rectangular, two groups of vertical plates 202 which are parallel to each other and the inner contour of the bottom of the support rod 3 with the maximum outer contour formed by connecting the two groups of vertical plates 202 are connected in parallel, that is, the two groups of vertical plates 202 which are parallel to each other are wrapped inside the bottom of the support rod 3, and the two corresponding groups of key blocks are arranged inside the support rod 3.
