[0027] The column 1 is provided with the connecting hole 3, and the connecting hole 3 is provided with the threaded hole 8, and the threaded hole 8 is used for being connected with the bolt 2, and the bolt 2 is used for being connected with the glass, and the glass is fixed on the column 1. DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range protected by the utility model.

[0029] The utility model is described as follows: Figures 1-3 The utility model is described as follows:

[0030] Embodiment: a safe glass clamp column, including column 1 and bolt 2, the column 1 is used as the support main body of whole structure, and is provided with connecting hole 3 on it, and the connecting hole 3 is provided with thread, and the purpose is to realize the threaded connection with bolt 2, to build up the stable connection framework, and provide the basis for subsequent glass clamping. At the same time, the glass is also provided with the hole that is connected with bolt 2 adaptation, and in actual installation process, the glass is accurately clamped and fixed between the screw head 4 of bolt 2 and column 1, and through the fastening effect of bolt 2, it is ensured that the glass can be stably installed on the column 1, and the basic demand of glass fixed in building decoration field is satisfied.

[0031] The screw head 4 of bolt 2 is cylindrical, and the annular positioning recess 5 is arranged on the radial outer side wall of screw head 4. The existence of this recess 5 is one of the key designs of the whole safety protection mechanism, and it cooperates with the subsequent cover body 6 and related components, and aims at preventing bolt 2 from being unauthorizedly disassembled, greatly improving the safety of glass clamp column.

[0032] ​Further comprising a cover 6 rotationally connected with the screw head 4, the cover 6 is provided with a connecting cavity 7 on the surface facing the screw head 4, the connecting cavity 7 is accurately matched with the screw head 4, and can be tightly connected with the screw head 4, so that the cover 6 can stably cover the screw head 4 after installation, effectively shielding the bolt 2 from the outside, preventing others from directly contacting the screw head 4 for disassembly operation.

[0033] A threaded hole 8 is arranged on the radial inner side wall of the connecting cavity 7, and a positioning pin 9 is threadedly connected in the threaded hole 8, and the front end of the positioning pin 9 is in sliding connection with the positioning groove 5. Through this cooperation, the axial fixed connection of the cover 6 and the screw head 4 is realized. That is to say, when the positioning pin 9 is embedded in the positioning groove 5, the cover 6 is firmly fixed in the axial direction and cannot be easily separated from the screw head 4, further strengthening the protection of the bolt 2. Even if someone tries to rotate the cover 6 to disassemble the bolt 2, since the cover 6 is only rotationally connected with the screw head 4 and is axially limited by the positioning pin 9, the rotation of the cover 6 will not drive the screw head 4 to rotate, thereby effectively avoiding the accidental disassembly of the bolt 2.

[0034] The cover 6 is rotationally connected with the screw head 4, and the screw head 4 and the cover 6 are axially fixedly connected through the cooperation of the positioning pin 9 and the positioning groove 5.

[0035] A receiving hole 10 coaxially corresponding to the threaded hole 8 is arranged on the outer side wall of the screw head 4, and the positioning pin 9 can move forward to completely enter the receiving hole 10. When it is necessary to disassemble the cover 6, the positioning pin 9 can be moved forward to completely enter the receiving hole 10, at this time, the positioning pin 9 releases the axial limitation of the cover 6 and the screw head 4, so that the cover 6 can be smoothly disassembled, providing the possibility for subsequent operation of the bolt 2.

[0036] An operation hole 11 corresponding to the threaded hole 8 is arranged on the outer side wall of the cover 6, and the diameter of the operation hole 11 is smaller than the diameter of the threaded hole 8. This size design can prevent the positioning pin 9 from coming out of the operation hole 11; it is also designed to facilitate the use of a special tool to accurately operate the positioning pin 9 through the operation hole 11, so that the positioning pin 9 can enter and exit the threaded hole 8 as needed, thereby realizing the control of the connection state of the cover 6 and the screw head 4.

[0037] In actual operation scenarios, the operator needs to use an adapted tool to carefully rotate the positioning pin 9 through the operation hole 11, so that it moves in the threaded hole 8 and completes the cooperation action with the positioning groove 5 or the receiving hole 10.

[0038] The tool is used to operate the positioning pin 9 through the operation hole 11, so that the positioning pin 9 can enter and exit the receiving hole 10.

[0039] Overall safety protection mechanism:

[0040] The core safety protection principle of the safety type glass clamp column is that the screw head 4 of the bolt 2 is covered in all directions by the cover body 6. In the daily state, others cannot directly contact the screw head 4, so they cannot operate the screw head 4 to rotate to disassemble the bolt 2. Even if someone tries to rotate the cover body 6, since the cover body 6 is rotationally connected with the screw head 4, the rotation of the cover body 6 cannot be transmitted to the screw head 4, and the screw head 4 cannot rotate, thereby eliminating the possibility of the bolt 2 being accidentally disassembled. Only when the cover body 6 is disassembled can the bolt 2 be directly operated. It is not easy to disassemble the cover body 6, and the positioning pin 9 needs to be inserted into the accommodating hole 10 on the screw head 4 to remove the axial restriction of the cover body 6 and the screw head 4, so that the cover body 6 can be disassembled. Only when the cover body 6 is rotated to the position where the positioning pin 9 is coaxial with the accommodating hole 10, the positioning pin 9 can be operated to move into the accommodating hole 10. For people who do not understand the structure mechanism, it is basically impossible to normally disassemble the cover body 6, because they are difficult to accurately rotate the cover body 6 to the appropriate position and simultaneously operate the positioning pin 9. Only when the structure design is familiar and the operation process is known, the cover body 6 is slowly rotated and the positioning pin 9 is operated to move forward, and by means of patience and accurate operation, when the cover body 6 is rotated to the position where the positioning pin 9 is coaxial with the accommodating hole 10, the positioning pin 9 can move forward into the accommodating hole 10, thereby realizing the disassembly of the cover body 6, and finally the bolt 2 can be contacted for subsequent operation. This series of complex and rigorous design greatly improves the safety of the glass clamp column, and effectively meets the high standard requirements of the building decoration field for the safety of the glass fixing structure.

[0041] The cover body 6 is installed after the bolt completes clamping and fixing of the glass (the positioning pin is first installed in the accommodating hole and then the cover body is installed), the length of the threaded hole and the depth of the positioning groove are equal to the length of the positioning pin, and the depth of the accommodating hole is greater than the length of the positioning pin.

[0042] In order to accurately control the positioning pin 9, the positioning pin 9 is provided with a hexagonal operation slot 12. In the actual operation scene, due to the existence of the operation hole 11, the operator can smoothly explore the hexagonal wrench through the operation hole 11 and accurately clamp it into the operation slot 12. By rotating the wrench, the positioning pin 9 can be stably driven to rotate. This design cleverly solves the problem of rotating the positioning pin 9 in a limited space. Compared with other complex or difficult operation methods, the cooperation of the hexagonal wrench and the operation slot 12 not only ensures the accuracy of the operation, but also takes advantage of the labor-saving characteristics of the wrench to efficiently complete the rotating in and out of the positioning pin 9 in the threaded hole 8, thereby flexibly controlling the connection state of the cover body 6 and the screw head 4.

[0043] The accommodating hole 10 is provided with a spring 13. This design adds convenience and stability to the entire disassembly and installation process. When the positioning pin 9 needs to enter the accommodating hole 10 to release the axial constraint of the cover body 6 and the screw head 4, the spring 13 will be compressed, storing elastic potential energy. Once the operation requirement reverses, that is, to rethread the positioning pin 9 and the threaded hole 8, the spring 13 will release the stored elastic force, exerting an outward pushing force on the positioning pin 9. With the aid of this force, the threaded portion of the positioning pin 9 can more smoothly align with the threads of the threaded hole 8, making it easier for the positioning pin 9 to achieve a tight and stable threaded connection with the threaded hole 8, greatly improving the efficiency and accuracy of the assembly process.

[0044] The side of the column 1 is fixedly connected with a fixed block 14, and the connecting hole 3 passes through the fixed block 14 and the column 1. The connecting hole 3 is designed to pass through the fixed block 14 and the column 1, greatly enhancing the stability and load-bearing capacity of the entire structure. The fixed block 14 acts as an additional support structure, sharing the pressure on the column 1 when it bears the weight of the glass and external force impact.

[0045] Two clamping pieces 15 are provided between the screw head 4 and the fixed block 14. The clamping pieces 15 are made of flexible material, taking into account the fragile nature of glass. Flexible materials such as rubber and silicone have good cushioning properties. During the glass installation process, as the bolt 2 is gradually tightened, the clamping pieces 15 will tightly adhere to the glass surface. On the one hand, they can fill any small gaps that may exist between the glass and the fixed components, preventing cracks from occurring due to uneven local stress. On the other hand, if the glass is subjected to slight external vibrations or impacts, the flexible clamping pieces 15 can absorb and disperse the impact force, providing an additional protective barrier for the glass, greatly reducing the risk of damage and extending the service life of the glass.

[0046] An annular limiting ring 16 is provided between the two clamping pieces 15. Its length is precisely set to be equal to the thickness of the glass, and this precise size matching plays a crucial role in protecting the glass.

[0047] The cross-section of the positioning groove 5 is V-shaped, and the front end of the positioning pin 9 is conical.

[0048] The cross-section of the column 1 is a square box structure. The square box structure has high bending stiffness and can effectively resist deformation when subjected to the weight of the glass, wind, and other lateral forces, maintaining its upright state.

[0049] The fixed block 14 is a shell-shaped structure with an opening facing the column 1, and the fixed block 14 is welded and fixed to the column 1.

[0050] The bottom of the stand 1 is provided with a fixed base 17. This design provides a solid foundation support for the entire glass clamp stand system. The fixed base 17 is usually designed with a larger contact area, which can uniformly distribute the load borne by the stand 1 to the ground or mounting plane, preventing the stand 1 from sinking, tilting and other problems due to uneven force on the bottom.

[0051] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
