DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-4 A wear-resistant carat tube includes a tube body 1, both ends of the tube body 1 are fixedly connected to a fixing ring 101, and the side wall of the fixing ring 101 is threadedly connected to a plurality of threaded bolts 102, and further includes:

[0025] The top of the side wall of the tube body 1 is fixedly connected to the upper mounting seat 2, and the bottom of the side wall of the tube body 1 is fixedly connected to the lower mounting seat 201. There are multiple sets of upper mounting seats 2 and lower mounting seats 201, and they correspond one to one. The upper surrounding tube 202 is clamped in the inner cavity of the upper mounting seat 2, and the lower surrounding tube 203 is clamped in the inner cavity of the lower mounting seat 201, and the upper surrounding tube 202 and the lower surrounding tube 203 are clamped together.

[0026] A fixing plate 204 is slidably connected to both sides of the inner wall of the upper mounting seat 2 and the lower mounting seat 201, and a first spring 205 is fixedly connected between the fixing plate 204 and the upper mounting seat 2;

[0027] The end of the side wall of the fixing plate 204 is set to be arc-shaped, and the fixing plate 204 is respectively fitted with the side walls of the upper surrounding tube 202 and the lower surrounding tube 203;

[0028] The first spring 205 is squeezed to generate a rebound force, and when the upper surrounding tube 202 is stuck in the inner cavity of the upper mounting seat 2, the rebound force of the first spring 205 is used to fix the upper surrounding tube 202. When the lower surrounding tube 203 is installed in the inner cavity of the lower mounting seat 201, the upper surrounding tube 202 and the lower surrounding tube 203 are clamped to each other, that is, the installation is completed. The upper surrounding tube 202 and the lower surrounding tube 203 can be replaced when they are worn, which is simple and convenient. The fixing ring 101 and the threaded bolt 102 can be used to fix multiple tube bodies 1 together.

[0029] Reference Figure 1-4 The bottom of the upper surrounding tube 202 is fixedly connected with a clamping column 3, and the clamping column 3 can extend into the inner cavity of the lower surrounding tube 203, and the side wall of the clamping column 3 is fixedly connected with a first clamping block 301;

[0030] A sliding post 302 is slidably connected to the inner wall of the lower surrounding tube 203, and a second clamping block 303 is fixedly connected to the end of the sliding post 302;

[0031] The side walls of the first clamping block 301 and the second clamping block 303 are both configured to be arc-shaped, and the end of the sliding column 302 is fixedly connected to the inner wall of the lower surrounding tube 203 by a second spring 304;

[0032] It should be noted that: when the upper surrounding tube 202 and the lower surrounding tube 203 are clamped together, the clamping column 3 at the bottom of the upper surrounding tube 202 is slid into the inner cavity of the lower surrounding tube 203. At this time, the first clamping block 301 on the side wall of the clamping column 3 contacts the second clamping block 303, and the first clamping block 301 squeezes the second clamping block 303 to slide into the inner cavity of the lower surrounding tube 203. At this time, the second spring 304 located between the sliding column 302 and the lower surrounding tube 203 is squeezed to generate a rebound force. When the first clamping block 301 moves below the second clamping block 303, under the action of the rebound force of the second spring 304, the second clamping block 303 slides to the side wall of the clamping column 3 and clamps the first clamping block 301. In this way, the upper surrounding tube 202 is clamped with the lower surrounding tube 203 using the clamping column 3 and the first clamping block 301.

[0033] Reference Figure 1-4 The end of the sliding column 302 is fixedly connected to a connecting column 305, and the connecting column 305 passes through the side wall of the lower surrounding tube 203, and the second spring 304 is located outside the connecting column 305;

[0034] A third spring 306 is fixedly connected to the inner wall of the lower surrounding tube 203, and the third spring 306 can fit with the bottom end of the clamping column 3;

[0035] It should be noted that: when the upper surround tube 202 and the lower surround tube 203 are clamped, the third spring 306 is squeezed to generate a rebound force. When the clamping needs to be released, the connecting column 305 is slid to the outside of the lower surround tube 203. At this time, the connecting column 305 drives the sliding column 302 and the second clamping block 303 to slide outward. The first clamping block 301 is not restricted by the second clamping block 303 at this time. Under the action of the rebound force of the third spring 306, the clamping column 3 slides upward, thereby releasing the clamping connection between the upper surround tube 202 and the lower surround tube 203, making it easy to replace.

[0036] Operation method: Install the upper surrounding tube 202 in the inner cavity of the upper mounting seat 2, and squeeze the upper surrounding tube 202 toward the inner cavity of the upper mounting seat 2, that is, the upper surrounding tube 202 contacts the side of the fixing plate 204. Since the side wall of the fixing plate 204 is set to be arc-shaped, the upper surrounding tube 202 squeezes the fixing plate 204 and slides into the inner cavity of the upper mounting seat 2. At this time, the first spring 205 is squeezed to generate a rebound force. When the upper surrounding tube 202 is stuck in the inner cavity of the upper mounting seat 2, the rebound force of the first spring 205 is used to fix the upper surrounding tube 202. Similarly, install the lower surrounding tube 203 in the inner cavity of the lower mounting seat 201;

[0037] The clamping column 3 at the bottom of the upper surrounding tube 202 is slid into the inner cavity of the lower surrounding tube 203. At this time, the first clamping block 301 on the side wall of the clamping column 3 contacts the second clamping block 303. The first clamping block 301 squeezes the second clamping block 303 and slides it downward into the inner cavity of the surrounding tube 203. At this time, the second spring 304 between the sliding column 302 and the lower surrounding tube 203 is squeezed to generate a rebound force. When the first clamping block 301 moves below the second clamping block 303, the second clamping block 303 slides to the side wall of the clamping column 3 under the rebound force of the second spring 304, and the first clamping block 301 is clamped. The upper surrounding tube 202 is thus connected to the lower surrounding tube 203 by means of the clamping column 3 and the first clamping block 301. At this time, the third spring 306 is squeezed to generate a rebound force. When the clamping needs to be released, the connecting column 305 is slid to the outside of the lower surrounding tube 203. At this time, the connecting column 305 drives the sliding column 302 and the second clamping block 303 to slide outward. The first clamping block 301 is not restricted by the second clamping block 303 at this time. Under the action of the rebound force of the third spring 306, the clamping column 3 slides upward, thereby releasing the clamping connection between the upper surrounding tube 202 and the lower surrounding tube 203, making it easy to replace.
