[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] A supporting and stable structure of a steel structure project, such as Figure 1 - Figure 5 As shown, it includes a fixing seat 1, a fixing seat 2 and a bolt 3, wherein a threaded barrel 4 threadedly connected to the bolt 3 is installed on the outer wall of the fixing seat 1, and the threaded barrel 4 is installed on the outer wall of the fixing seat 1 by welding, so that the angle and position of the threaded barrel 4 cannot be changed, so that when installing the bolt 3, it is only necessary to twist the bolt 3, and at the same time, the outer end of the threaded barrel 4 is sealed, so that after the bolt 3 is installed, the end connected to the threaded barrel 4 will not leak out, thereby reducing the corrosion of the end thread of the bolt 3 by external humid air, etc., and effectively reducing the probability of rust on the bolt 3. A limit box 5 corresponding to the bolt 3 is installed on the outer wall of the fixing seat 2, and the thickness of the limit box 5 corresponds to the distance between the outer end of the bolt 3 and the outer wall of the fixing seat 2, so that The outer end of the bolt 3 will not leak out of the fixing seat 2. At the same time, because the outer wall rotation axis of the limit box 5 is installed with a limit door 6 that is in contact with the outer end of the bolt 3, and the outer wall of the limit door 6 is in contact with the limit box 5, after the limit door 6 is closed, the outer end of the bolt 3 will be restricted by the limit door 6, and then if the bolt 3 wants to move outward, it will be blocked by the limit door 6. In addition, because the side wall of the limit box 5 is provided with a locking mechanism for fixing the limit door 6, the limit door 6 will be locked in position after closing, and then the bolt 3 cannot move outward after installation, thereby preventing the bolt 3 from being seriously loosened and affecting the connection and fixation between the fixing seat 1 and the fixing seat 2, thereby effectively improving the fixing effect of the fixing seat 1 and the fixing seat 2 when in use.

[0033] See also Figure 4 and Figure 5 A through slot for installing the bolt 3 is opened in the middle of the limit box 5, so that the bolt 3 can be installed to the outer wall of the fixing seat 2 through the through slot. At the same time, because the diameter of the through slot is larger than the diameter of the outer end of the bolt 3, during the process of installing and removing the bolt 3, the tool for removing the bolt 3 can be smoothly inserted into the through slot to remove and install the bolt 3, preventing the setting of the limit box 5 from affecting the installation and removal of the bolt 3.

[0034] See also Figure 2 - Figure 4Because the outer wall of the limit door 6 is the same size as the outer wall of the limit box 5, when the limit door 6 is attached to the limit box 5, the limit door 6 will block the through slot, thereby reducing the influence of the external environment on the bolt 3. At the same time, a torsion spring for resetting the limit door 6 is provided at the position where the limit box 5 is rotatably connected to the limit door 6. In the process of closing the limit door 6, the torsion spring will be stressed. When the restriction of the limit door 6 is released, the torsion spring will open the limit door 6, so that the limit door 6 will automatically open after losing the restriction. The bolts 3 are subsequently removed, and a sealing ring 14 is installed on the outer wall of the limit box 5 to be in contact with the limit door 6. During the closing process of the limit door 6, the sealing ring 14 will be squeezed, and the diameter of the sealing ring 14 is larger than the diameter of the through groove, so that the sealing between the limit door 6 and the limit box 5 is further improved. Even if water falls onto the limit box 5 later, the sealing ring 14 will guide the water and guide it out, thereby further improving the sealing between the limit door 6 and the limit box 5.

[0035] See also Figure 2 - Figure 5 The locking mechanism is composed of a positioning block 7, a lower limiting block 8, an upper limiting block 9, a positioning rod 10, a positioning groove 11, an auxiliary rod 12 and a stopper 13, wherein the positioning block 7 is fixedly mounted on the end of the limiting door 6, and the side wall of the positioning block 7 is in contact with the outer wall of the limiting box 5, and there is a gap between the end of the positioning block 7 and the outer wall of the fixing seat 2, so that when the limiting door 6 fails to be automatically opened by the torsion spring, the limiting door 6 can be opened by depressing the positioning block 7, further ensuring that the limiting door 6 can be opened smoothly;

[0036] Furthermore, a lower limit block 8 abutting against the bottom of the positioning block 7 is fixedly installed on the outer wall of the limit box 5, and an upper limit block 9 abutting against the top of the positioning block 7 is fixedly installed on the outer wall of the limit box 5. At the same time, a positioning rod 10 is slidably installed in the lower limit block 8, and a positioning groove 11 for sliding the positioning rod 10 is penetrated and opened in the lower limit block 8, the upper limit block 9 and the positioning block 7, and the length of the positioning rod 10 is greater than the sum of the lengths of the positioning grooves 11 in the positioning block 7 and the lower limit block 8, so that the positioning rod 10 is pushed so that it can smoothly slide into the positioning groove 11 in the upper limit block 9, so that the positioning rod 10 will be located in the positioning grooves 11 in the lower limit block 8, the upper limit block 9 and the positioning block 7, thereby limiting the position of the limit door 6 at this time. At the same time, the limit door 6 at this time will have a force to continuously return to its original position under the action of the sealing ring 14 and the torsion spring, so that the positioning rod 10 will also be subject to the pressure given by the positioning block 7, thereby ensuring the fixity of the position of the positioning rod 10;

[0037] Furthermore, a strong magnet is installed in the positioning block 7, and a magnet that is magnetically attracted to the strong magnet in the positioning block 7 is installed on the outer wall where the positioning rod 10 and the positioning groove 11 in the positioning block 7 are attached, so that when the positioning rod 10 is pushed to the limited position, it will be fixed under the action of the magnet and the strong magnet, further ensuring the fixity of the positioning rod 10 after sliding, and further ensuring the fixity of the limit door 6 when the blocking bolt 3, and at the same time, the end corners of the positioning rod 10 and the opening corners of the positioning groove 11 are both beveled The angle design makes it easy for the positioning rod 10 to enter the positioning groove 11, and a block 13 for supporting the positioning rod 10 is installed at the bottom of the limit box 5. When the positioning rod 10 is pulled to release the fixation of the limit door 6, the block 13 will restrict the positioning rod 10 to prevent the positioning rod 10 from sliding out of the positioning groove 11 of the lower limit block 8. At the same time, the distance between the block 13 and the top of the lower limit block 8 is ≥ the length of the positioning rod 10, ensuring that the restriction on the limit door 6 has been released when the positioning rod 10 contacts the block 13.

[0038] See also Figure 2 - Figure 4 An auxiliary rod 12 is slidably installed in the positioning groove 11 of the upper limit block 9, and the cross-section of the auxiliary rod 12 is T-shaped, so that the auxiliary rod 12 cannot completely slide into the upper limit block 9, avoiding it from entering the positioning groove 11 in the positioning block 7 to affect the opening of the limit door 6, and the length of the auxiliary rod 12 in the positioning groove 11 is the same as the length of the positioning groove 11 of the upper limit block 9, so that in the process of pushing the positioning rod 10 to limit the limit door 6, the positioning rod 10 will push the auxiliary rod 12, so that the auxiliary rod 12 will The auxiliary rod 12 slides out of the positioning groove 11. At the same time, because the auxiliary rod 12 is hollow inside, its weight is much smaller than the adsorption force between the strong magnet and the magnet, so that the auxiliary rod 12 cannot push the positioning rod 10 when no external force is received. When the position of the positioning rod 10 in the positioning groove 11 is relatively firm, which makes it very difficult to pull the positioning rod 10, the auxiliary rod 12 can be pressed downward to make the auxiliary rod 12 push the positioning rod 10 down, causing the magnet in the positioning rod 10 to be offset from the position of the strong magnet. At this time, it is easy to pull the positioning rod 10.

[0039] The working principle of the utility model is as follows: when in use, the outer wall of the rectangular steel can be tightly clamped by the fixing seat 1 and the fixing seat 2, and then the bolt 3 is threadedly installed into the threaded tube 4, so that the fixing seat 1 and the fixing seat 2 are fixed by the bolt 3 and the threaded tube 4, and then the limit door 6 is pressed so that the outer wall of the limit door 6 conflicts with the end of the bolt 3, and then the positioning rod 10 is pushed so that the end of the positioning rod 10 enters the positioning groove 11 in the upper limit block 9. At this time, the positioning rod 10 will be magnetically attracted to the strong magnetic block in the positioning block 7, so that the position of the positioning rod 10 is fixed. In subsequent work, the limit door 6 will restrict the bolt 3 so that it cannot slide outward, thereby preventing the bolt 3 from loosening;

[0040] When the bolt 3 needs to be removed, the positioning rod 10 is pulled downward until it contacts the stop block 13. At this time, the positioning rod 10 will be separated from the positioning block 7, and then the limit door 6 will automatically reset under the action of the torsion spring. If the limit door 6 fails to open automatically, the user can also open the limit door 6 by depressing the positioning block 7 to expose the bolt 3. At this time, the tool can be used to take the bolt 3 and remove it.
