Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: The three-layer upright tie rod connection mechanism includes: upper bed board body 1, column body 2, lower bed board body 3, first tie rod 4, second tie rod 5, second protective sleeve body 14, third protective sleeve body 15, first positioning groove 16 and second positioning groove 17.

[0019] Specific examples Figure 1 , Figure 2 and Figure 3 As shown, first, the upper bed board body 1 is placed horizontally. Below the upper bed board body 1, the upright body 2 and the lower bed board body 3 are placed in sequence. The edges of the upright body 2 and the lower bed board body 3 are flush with the edge of the upper bed board body 1. A first positioning groove 16 is formed at the bottom of the upper bed board body 1. A first positioning wheel 7, which has a circular structure, is placed on the upper side of the upright body 2. The upright body 2 is pushed, causing the first positioning wheel 7 to engage inside the first positioning groove 16. At this time, the bottom end of the upper bed board body 1 is aligned with the upright body 2. The upper end face makes contact. Similarly, the bottom of the column body 2 is provided with a second positioning groove 17. The second positioning wheel 8, which has a circular structure, is placed on the upper side of the lower bed plate body 3. The lower bed plate body 3 is pushed so that the second positioning wheel 8 engages with the interior of the second positioning groove 17. At this time, the bottom end face of the column body 2 makes contact with the upper side of the lower bed plate body 3. Select a first pull rod 4 and a second pull rod 5 with appropriate diameters. Place the first pull rod 4 and the second pull rod 5 vertically. Place the first pull rod 4 to the left of the second pull rod 5. After the first pull rod 4 and the second pull rod 5 are aligned with the two circular openings at the upper end of the upper bed board body 1, and then pressed down, the outer walls of the first pull rod 4 and the second pull rod 5 will generate sliding friction with the inner walls of the upper bed board body 1, the upright body 2, and the lower bed board body 3, respectively, until the first pull rod 4 and the second pull rod 5 are completely inserted into the interior of the upper bed board body 1, the first positioning groove 16, the upright body 2, the second positioning groove 17, and the lower bed board body 3. Then, the upper ends of the first pull rod 4 and the second pull rod 5 are screwed... The first fastening cap 6 is screwed onto the lower end of the first pull rod 4 and the second pull rod 5, and the second fastening cap 9 is screwed onto the lower end of the first fastening cap 6 and the second fastening cap 9. The first fastening cap 6 and the second fastening cap 9 on the same longitudinal axis are tightened inward, which shortens the connection gap between the upper bed board body 1, the column body 2 and the lower bed board body 3. The upper bed board body 1, the column body 2 and the lower bed board body 3 are fastened together, which facilitates the strengthening of the internal fastening of the three-layer vertical pull rod connection mechanism.

[0020] Specific examples Figure 1 , Figure 4 and Figure 5As shown, four sets of first protective sleeve bodies 10 are selected and pressed against the four corners of the upper bed board body 1. The inner top of the first protective sleeve body 10 contacts the upper surface of the upper bed board body 1, and friction is generated between the inner wall of the first protective sleeve body 10 and the outer wall of the upper bed board body 1. The first protective sleeve body 10 slides and connects with the upper bed board body 1 until the inner walls of the four sets of first protective sleeve bodies 10 are completely in contact with the four corners of the upper bed board body 1. At this time, the first protective sleeve body 10 and the upper bed board body 1 are in contact. Similarly, the second protective sleeve body 14 is attached to the four corners of the column body 2. The cross-section of the second protective sleeve body 14 is L-shaped. The third protective sleeve body 15 is attached to the four corners of the lower bed board body 3. The bottom of the inner part of the third protective sleeve body 15 contacts the bottom of the lower bed board body 3. Under the combined action of the first protective sleeve body 10, the second protective sleeve body 14 and the third protective sleeve body 15, the corners of the three-layer upright tie rod connection mechanism are wrapped, which facilitates the improvement of the protection of the three-layer upright tie rod connection mechanism.

[0021] Specific examples Figure 4 and Figure 5As shown, the first protective sleeve body 10, the second protective sleeve body 14, and the third protective sleeve body 15 are all placed vertically. Adjusting rods 11 are horizontally installed at the inner ends of each of the three protective sleeve bodies 10, 14, and 15. The adjusting rods 11 of adjacent sets of the first protective sleeve bodies 10 are kept on the same horizontal plane. Fastening plates 12 are nested around the adjusting rods 11 on the same horizontal line. The fastening plates 12 have a "U"-shaped structure, and a "U"-shaped groove is formed inside the fastening plates 12. After aligning the groove inside the fastening plates 12 with two adjacent sets of adjusting rods 11 on the same horizontal plane and pressing them down, friction occurs between the inner wall of the fastening plates 12 and the outer wall of the adjusting rods 11. The fastening plates 12 and the adjusting rods 11 are slidably connected until the inner end of the fastening plates 12 contacts the outer surface of the corresponding upper bed board body 1, column body 2, or lower bed board body 3. At this time, the adjusting rod 11 is engaged with the fastening sleeve plate 12. After the first protective sleeve body 10, the column body 2, and the third protective sleeve body 15 are all tightly fitted with their corresponding corners, the fastening bolt 13 is horizontally screwed on at the connection between the fastening sleeve plate 12 and the adjusting rod 11. The fastening bolt 13 passes through the interior of the fastening sleeve plate 12 and the adjusting rod 11, and the outside of the fastening bolt 13 is provided with a threaded structure. Under the action of the fastening bolt 13, the connection gap between the fastening sleeve plate 12 and the corresponding adjusting rod 11 is shortened. Under the action of the fastening bolt 13, the fastening sleeve plate 12 and the adjusting rod 11 are tightly connected. At this time, the two adjacent sets of first protective sleeve bodies 10, the two adjacent sets of second protective sleeve bodies 14, and the two adjacent sets of third protective sleeve bodies 15 are all tightly fitted with their corresponding corners, which facilitates the improvement of the firmness of the connection between the protective sleeve and the corner of the three-layer upright tie rod connection mechanism. This is the usage method of the three-layer upright tie rod connection mechanism.
