[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In this invention, through the cooperation between the bottom ring and the movable ring, as well as the positioning rod and the positioning hole, the movable ring can be moved downward. At the same time, when the spring is compressed, the movable ring can be moved upward when the spring is reset. This allows the bottom ring to drive the reinforcing rib to move up and down, which in turn allows the top ring to move up and down. Through the cooperation between the rotating column and the upright column, as well as the bottom block and the insert rod, when the top ring moves upward, the top ends of the two insert rods are respectively located inside the two insertion holes, thereby fixing the top ring and the top sleeve. When the top ring moves downward, the two insert rods are respectively separated from the two insertion holes, thereby facilitating the release of the top ring and the top sleeve, and thus facilitating the disassembly and assembly of the reinforcing rib.

[0017] (2) The invention enables the reinforcing rib to pass through the positioning groove through the cooperation between the movable ring and the vertical rod, as well as the top sleeve and the positioning groove. At the same time, the bottom of the bottom ring is in contact with the movable ring. Through the cooperation between the positioning rod and the positioning hole, the reinforcing rib is in close contact with the outer side of the tubular conductor, thereby facilitating the positioning and installation of the reinforcing rib.

[0018] (3) The invention enables the two vertical plates to move and rotate through the cooperation between the movable block and the outer ring, as well as the connecting rod and the side plate. At the same time, the second spring is stretched and the clamping plate is rotated through the connecting block. When the top sleeve is located between the two clamping plates, the two springs reset so that the two movable blocks can move closer to each other, and then the two clamping plates can move closer to each other, so that the two clamping plates can be located on the inner side of the two clamping slots respectively, and then the top ring and the top sleeve can be fixed, so that the reinforcing rib can be firmly fixed on the outer side of the reinforcing rib.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1, by Figures 1-8 The present invention includes a tubular conductor 1, with reinforcing ribs 3 installed at equal angles on the outer side of the tubular conductor 1, a reinforcing rib positioning mechanism 2 installed at the bottom of the reinforcing ribs 3, and a reinforcing rib fixing mechanism 5 installed at the top of the reinforcing ribs 3. Both the reinforcing rib fixing mechanism 5 and the reinforcing rib positioning mechanism 2 are connected to the tubular conductor 1. A locking mechanism 4 is installed on the outer side of the reinforcing rib fixing mechanism 5 and is connected to the reinforcing ribs 3.

[0032] In Example 2, based on Example 1, the reinforcing rib positioning mechanism 2 includes a bottom sleeve 201 fixed to the outside of the tubular conductor 1 near the bottom. A top groove 205 is formed on the top of the bottom sleeve 201, and a movable ring 204 is movably installed inside the top groove 205. Positioning holes 203 are formed at equal angles on the top of the movable ring 204. A bottom ring 6 is fixedly installed at the bottom of the reinforcing rib 3, with the bottom of the bottom ring 6 fitting against the top of the movable ring 204. A positioning rod 7 is fixedly connected at equal angles to the bottom of the bottom ring 6. Position rod 7 is located inside positioning hole 203. A fixing ring 207 is fixedly connected to the inside of top groove 205. A vertical rod 202 is fixedly connected to the bottom of fixing ring 207 at equal angles. The bottom end of vertical rod 202 is fixedly connected to the bottom of the inside of top groove 205. Movable ring 204 is movably connected to vertical rod 202. A spring 206 is connected to the bottom of movable ring 204 at equal angles. The bottom end of spring 206 is connected to the bottom of the inside of top groove 205. Spring 206 is movably sleeved with vertical rod 202.

[0033] The inner diameter of the fixed ring 207 is equal to the outer diameter of the bottom ring 6, which allows the bottom ring 6 to be located inside the top groove 205. When the bottom ring 6 is in contact with the movable ring 204, the positioning rod 7 is located inside the positioning hole 203, thereby limiting the bottom ring 6 and facilitating the tight contact between the reinforcing rib 3 and the outer side of the tubular conductor 1.

[0034] In Example 3, based on Example 1, the reinforcing rib fixing mechanism 5 includes a top ring 501 located outside the tubular conductor 1. The top of the reinforcing rib 3 is fixedly connected to the bottom of the top ring 501. Mounting blocks 502 are fixedly connected to both sides of the top ring 501. Rotating columns 508 are rotatably connected to the bottom of each of the two mounting blocks 502. Columns 507 are fixedly connected to the bottom ends of each of the two rotating columns 508. Bottom blocks 506 are fixedly connected to the bottom ends of each of the two columns 507. Each of the tops of the block 506 is fixedly installed with a plug rod 505. The outer side of the tubular conductor 1 is fixedly installed with a top sleeve 504. The outer side of the top sleeve 504 is symmetrically provided with a slot 503. The top sleeve 504 is located below the top ring 501. The inner side of the top sleeve 504 is provided with a positioning groove 509 at equal angles. The positioning groove 509 is movably engaged with the reinforcing rib 3. The bottom sides of the top sleeve 504 are provided with plug holes 5010. The tops of the two plug rods 505 are located inside the two plug holes 5010 respectively.

[0035] When the bottom ring 6 contacts the movable ring 204 and moves downward, the spring 206 is compressed. At the same time, the top ring 501 is above the top sleeve 504. Then, the two bottom blocks 506 are rotated, which in turn drives the two insertion rods 505 to rotate until the two insertion rods 505 are respectively below the two insertion holes 5010. When the spring 206 returns to its original position, it drives the bottom ring 6 to move upward, and through the reinforcing rib 3, it drives the top ring 501 to move upward, which in turn drives the two bottom blocks 506 to move upward until the tops of the two insertion rods 505 are respectively inside the two insertion holes 5010. At this time, the top ring 501 and the top sleeve 504 are fixed, and finally the installation of the reinforcing rib 3 is completed.

[0036] In Example 4, based on Example 1, the locking mechanism 4 includes two side sleeves 401 symmetrically fixed to the outside of the top ring 501. A vertical plate 402 is installed on the outer side of each side sleeve 401. A connecting block 404 is fixedly installed on the side of each vertical plate 402 that is close to each other. A locking plate 403 is fixedly installed on the side of each connecting block 404 that is close to each other. The two locking plates 403 are respectively located inside the two locking slots 503. A side rod 408 is fixedly installed on the outer side of the side sleeve 401. A side block 4012 is fixedly connected to one end of the side rod 408. A locking hole 4010 is opened on one side of the side block 4012. A locking mechanism 4012 is movably installed on the outer side of the side rod 408. Movable block 4013, spring 407 is connected between movable block 4013 and side sleeve 401, spring 407 is movably sleeved with side rod 408, outer ring 406 is movably installed on the outer side of movable block 4013, connecting rod 409 is fixedly connected at equal angles on one side of outer ring 406, side plate 405 is fixedly connected to one end of connecting rod 409, side plate 405 is fixedly connected to vertical plate 402, a locking rod 4011 is opened on one side of side plate 405, locking rod 4011 is adapted to locking hole 4010, outer groove 4014 is opened on the outer side of movable block 4013, movable block 4013 is movably locked with outer ring 406 through outer groove 4014;

[0037] First, pull the two side plates 405, causing the two locking rods 4011 to move away from each other until the two locking rods 4011 separate from the two locking holes 4010 respectively. At the same time, the two outer rings 406 move away from each other, and the two movable blocks 4013 move away from each other. At this time, the two springs 407 are stretched. Then rotate the two side plates 405, causing the two vertical plates 402 to rotate. Through the two connecting blocks 404, the two locking plates 403 are rotated until the top sleeve 504 is located between the two locking plates 403. Then release the control of the two side plates 405. At this time, the two springs 407 reset, causing the two movable blocks 4013 to move closer to each other, and causing the two side plates 405 to move closer to each other. At the same time, the two locking plates 403 move closer to each other until the two locking plates 403 are located inside the two locking slots 503 respectively. At this time, fix the top sleeve 504 and the top ring 501, so that the reinforcing rib 3 is firmly fixed on the outside of the reinforcing rib 3.
