[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 2 , Figure 3As shown, the present invention discloses a combined detachable steel structure self-locking connection device, comprising: a second column 2, consisting of a column body 20, a connecting part 21, and a locking part 22, wherein the connecting part 21 is located at the lower end of the second column 2 and has a reduced radial dimension, and the locking part 22 is located at the end of the connecting part 21; a first column 1, wherein a self-locking connection structure 10 is provided on its upper part, the self-locking connection structure 10 including an unlocking plate 15 located on the outside of the first column 1 and a slider 11 located on the inside; the unlocking plate 15 and the slider 11 are connected by a connector 12. The component 12 passes through the through hole opened on the first column 1, allowing the self-locking connection structure 10 to slide horizontally along the through hole; the slider 11 is provided with an engagement space 111 for accommodating and restricting the locking part 22; the limiting plate 14 is provided on the inner wall of the first column 1, forming a guide space together with the inner wall surface of the first column 1, and the slider 11 is partially accommodated in the guide space; the spring 13 is sleeved on the connector 12 and is provided between the slider 11 and the inner wall of the first column 1; the clamp unlocker 16 is slidably sleeved on the outer wall of the first column 1.

[0025] Specifically, the connecting part 21 of the second column 2 can be inserted into the inner cavity of the first column 1. After its locking part 22 contacts the slider 11 inside the first column 1, the spring 13 is compressed due to gravity, causing the slider 11 to move towards the inner wall of the first column 1 until the locking part 22 is engaged in the engagement space 111. At this time, the slider 11 will fit tightly against the locking part 22 due to the spring action, locking the locking part 22. At this time, the apex angle formed between the connecting part 21 of the second column 2 and the column body 20 due to the narrowing of the inner diameter just meets the column opening of the first column 1. The top of the locking part 22 of the second column 2 abuts against the limiting plate 14. The two work together to effectively distribute the weight of the second column 2 and prevent the second column 2 from moving downward. A part of the second column 2 enters the range of the first column body, and the outer wall of the second column 2 fits against the inner wall of the first column 1, giving it anti-shear and anti-torsion properties.

[0026] At this point, the lasso unlocker 16 is raised to the connection between the first and second columns and secured. The lasso unlocker serves two purposes: first, it unlocks the columns; second, it secures the connection between the middle and bottom columns. Because the middle column is inserted into the bottom column, if the vertical load is too large, lateral displacement may occur at the joint between the top of the middle and bottom columns. Placing the lasso unlocker at the connection can limit any potential lateral deformation at the joint between the top of the middle and bottom columns.

[0027] like Figure 7 As shown, in some embodiments, the longitudinal section of the slider 11 is "F" shaped, including a limiting wall 112, a supporting wall 113 and an anti-detachment plate 114. The limiting wall 112 and the supporting wall 113 together form an engaging space 111, and the anti-detachment plate 114 is disposed at the bottom of the slider 11.

[0028] Specifically, such as Figure 7As shown, the slider 11 has a "waist" above the anti-detachment plate, which is accommodated within a guide space formed by the limiting plate 14 and the inner wall surface of the first column 1. When the slider 11 is subjected to an upward pulling force, the anti-detachment plate 114 abuts against the limiting plate 14, resisting the longitudinal displacement of the slider 11. That is, the limiting plate 14 and the anti-detachment plate 114 cooperate to constrain the vertical displacement of the slider 11, and cooperate with the connecting member 12 and the guide space to allow the slider 11 to slide in the horizontal direction.

[0029] like Figure 9 As shown, in some embodiments, the cross-section of the limiting plate 14 is U-shaped, and part of the slider 11 is accommodated in the groove of the limiting plate 14.

[0030] Specifically, the groove design of the limiting plate 14 allows the limiting plate 14 and the inner wall surface of the first column 1 to jointly form a guide space. This guide space allows the slider 11 to slide horizontally relative to the column of the first column 11 in the space, while restricting the slider 11 to make Z-direction displacement.

[0031] In addition, the limiting plates are modularized in the specific implementation, with two U-shaped or concave limiting plates installed inside each structural column. Before installation, the two limiting plates are not fixed to the column body. After the self-locking connection structure 10 is installed, the limiting plates are then fastened to the waist-retracted position of the slider, and then rigidly connected to the structural column. Installation is completed at the corresponding positions on the opposite side of the column, and finally, the contact surfaces between the two limiting plates are fixedly connected.

[0032] like Figure 10 As shown, after the contact surfaces between the two limiting plates are fixedly connected, the whole structure forms an "H" shape. The two limiting plates work together to ensure the strength of the limiting plates after installation, provide the tensile strength of the slider, facilitate processing and transportation before installation, and can be adapted to different column structures, increasing the adaptability of the device.

[0033] As described above, the design of the limiting plate 14 has multiple functions: it can limit the displacement of the connecting part 21 from below; it can enhance the connection between the slider and the inner wall; and it can also resist the upward movement of the slider by generating a reverse force together with the anti-detachment plate when the slider is subjected to an upward force.

[0034] like Figure 8 As shown, in some embodiments, the unlocking plate 15 is provided with a pre-drilled hole, and the connector 12 passes through the pre-drilled hole and is connected to the slider provided inside the column body; an unlocking ramp 151 is provided on the side of the first column 1 near the column body.

[0035] like Figure 4 As shown, the lower part of the clamp unlocker 16 is provided with a clamp unlocking slope 161 that cooperates with the unlocking slope 151.

[0036] Specifically, when unlocking is required, simply open the lasso unlocker 16. At this time, the lasso unlocker 16 will slide down the first post 1 along with the lasso unlocking ramp 161 due to gravity. When it contacts the unlocking ramp 151, the lasso unlocking ramp 161 will enter between the unlocking plate 15 and the outer wall of the first post 1 along the ramp, separating the slider system from the post head and realizing unlocking.

[0037] like Figure 2 As shown, the connector 12 is disposed on the upper and lower sides of the limiting plate 14.

[0038] like Figure 2 , 3 As shown, the outer wall of the column body 20 of the second column 2 is provided with a hook 23.

[0039] like Figure 4 As shown, the clamp unlocker 16 also includes a spring lock 162.

[0040] Specifically, when using the device, raise the clamp unlocker to the hook of the second column, connect the spring lock on the clamp unlocker to the hook, and fix it at the connection between the first and second columns. When unlocking, unlock the spring lock on the clamp unlocker to separate it from the hook of the second column, and then lower the clamp unlocker. Since there is an unlocking plate on the outside of the column, and there is an unlocking ramp on the side of the plate near the column, after the clamp unlocker falls, it will separate the slider from the locking part along the ramp, thus unlocking the device.

[0041] In some embodiments, the connector is a bolted connector.

[0042] like Figure 8 As shown, there are four connectors arranged in two rows and two columns on the unlocking plate 15. The number of connectors can be adjusted according to the actual situation in actual use.

[0043] like Figure 2 As shown, the combined detachable steel structure self-locking connection device also includes an intermediate conversion column 3. The upper column of the intermediate conversion column 3 is provided with a self-locking connection structure 10, which is exactly the same as the self-locking connection structure 10 of the first column 1. The lower column structure of the intermediate conversion column 3 is exactly the same as the lower column structure of the second column 2, so as to realize the overlapping connection of column segments and form a continuous integral column.

[0044] To use, please follow these steps for installation: S1: Fix the first column to ensure its verticality; S2: The intermediate conversion column is hoisted, and the connecting part of the intermediate conversion column is vertically inserted into the inner cavity of the first column. Its locking part contacts the slider and compresses the preload spring, causing the slider to move towards the inner wall of the first column until the locking part is engaged in the engagement space, thereby achieving longitudinal locking and elastic buffering. S3: Raise the clamp unlocker to the hook of the intermediate conversion column, connect the spring lock on the clamp unlocker to the hook, and fix it at the connection between the first column and the intermediate conversion column; S4: Intermediate transition columns can be connected sequentially, just like the connection between intermediate transition columns and the first column, until the corresponding height is reached. Then, the second column is hoisted and capped to achieve the design height. S5: Unlock. Unlock the spring lock on the clamp unlocker to separate it from the hook of the intermediate conversion column. Then, lower the clamp unlocker. Since there is an unlocking plate on the outside of the column, and an unlocking ramp on the side of the plate near the column, the clamp unlocker will follow the ramp to separate the slider from the locking part after it falls, thus unlocking.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
