[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a novel quick-installation structure for a weighing platform, comprising a fixed base 1 and a mounting plate 2. The fixed base 1 has a T-shaped structure at its bottom embedded in a concrete foundation, and a circular platform at its top. The fixed base 1, embedded in the concrete foundation, has a central positioning post 3 with an inverted conical guide surface and multiple L-shaped grooves 4 arranged around it. The central positioning post 3 and the fixed base 1 are integrally formed metal components. The L-shaped grooves 4 are directly machined into the annular area on the upper surface of the fixed base 1. The mounting plate 2 is fixed to the reinforcing ribs on the bottom surface of the weighing platform using an array of high-strength countersunk bolts, ensuring uniform force transmission and preventing protrusion from the bottom of the platform. Its lower surface has a conical guide sleeve 5 that mates with the central positioning post 3, and corresponding to each L-shaped groove 4. The locking slider assembly includes a slider 6, an elastic element 7, and a limiting pin 8. The slider 6 is slidably mounted in the lateral sliding cavity of the mounting plate 2 via the elastic element 7. The limiting pin 8 is hinged to the pin hole at the front end of the slider 6 via a miniature rotating shaft and is equipped with a torsion spring to keep it perpendicular to the sliding direction in the free state. This structure achieves rapid self-centering guidance by aligning the mounting plate 2 with the fixed base 1 and lowering it vertically. The inverted conical guide surface of the central positioning post 3 cooperates with the positive conical guide sleeve 5 to ensure accurate axial positioning of the mounting plate 2 and the fixed base 1. At the same time, during the pressing down of the mounting plate 2, the slider 6 enters synchronously under the guidance of the vertical guide section of the L-shaped slide groove 4. When it reaches the horizontal locking section, the elastic element 7 provides radially outward elastic force to push the slider 6 along the side. Moving towards the sliding cavity, the limiting pin 8 at the end of the slider 6 rotates into the horizontal locking section of the L-shaped slide groove 4. When the slider 6 slides to the end of the horizontal locking section, axial locking is formed, thus completing the quick connection and limiting between the mounting plate 2 and the fixed base 1. The entire process does not require bolt fastening, making operation simple. During disassembly, only upward force and slight rotation are needed to disengage the limiting pin 8 from the arc-shaped stop 41 and allow it to exit in the opposite direction along the L-shaped slide groove 4. This achieves efficient and repeatable disassembly and assembly operations, effectively solving the problems of long installation time, difficult disassembly and assembly, thread stripping and positioning deviation caused by repeated disassembly and assembly due to reliance on bolt fastening in the existing technology, as well as the alignment difficulties and cumbersome adjustments caused by the lack of integrated self-guiding and limiting functions. The L-shaped slide groove 4 consists of a vertical guide section and a horizontal... The locking section consists of a horizontal locking section with an upwardly protruding arc-shaped stop 41 at its end. A limiting pin 8 is hinged to the front end of the slider 6 via a pivot, and the outer end of the limiting pin 8 has a groove that matches the arc-shaped stop 41. When the mounting plate 2 is pressed down into place and the slider 6 slides along the L-shaped groove 4 from the vertical guide section into the horizontal locking section and to the end, the limiting pin 8 rotates under the drive of the slider 6, and the groove at its outer end aligns with and engages with the upper part of the arc-shaped stop 41, forming an axial limit. This prevents the mounting plate 2 from vertically dislodging due to vibration or external force during use. At the same time, the cooperation between the arc-shaped stop 41 and the groove restricts horizontal displacement, ensuring the stability of the connection, thereby achieving automatic locking and double anti-loosening functions. The slider 6 has a T-shaped structure.Its lateral portion is embedded in the lateral sliding cavity of the mounting plate 2 and connected to the inner wall of the sliding cavity by an elastic element 7 composed of a compression spring, giving it a radial retraction tendency. This structure ensures that the slider 6 can smoothly enter the vertical guide section of the L-shaped slide groove 4, and when it reaches the horizontal locking section, the elastic force provided by the elastic element 7 pushes the slider 6 outward, so that the limiting pin 8 at its end can accurately engage under the arc-shaped stop 41 to complete the locking action. In addition, this structure also allows the limiting pin 8 to be pulled out from under the arc-shaped stop 41 by applying appropriate force to overcome the elastic force of the elastic element 7 during disassembly, realizing the retraction of the slider 6 and easy disassembly of the entire device, improving the flexibility and maintainability of the overall system. The inner wall of the guide sleeve 5 is coated with a wear-resistant polytetrafluoroethylene (PTFE) layer, and its taper is consistent with the guide surface of the central positioning post 3. This structure, with its conical guide sleeve 5 and the inverted conical guide surface of the central positioning post 3, achieves rapid self-centering guidance through their consistent taper, ensuring precise axial positioning of the mounting plate 2 and the fixed base 1. The wear-resistant PTFE coating on the inner wall effectively reduces the coefficient of friction between the conical surfaces, improves guiding smoothness, and also has good wear resistance and self-lubricating properties, reducing wear on the metal surface during long-term frequent disassembly and assembly, extending the service life of the guide structure, and ensuring high positioning accuracy even after multiple disassembly and assembly. The lateral sliding cavity of the mounting plate 2 is equipped with a removable sealing cover 9. The sealing cover 9 is detachably installed on the outside of the mounting plate 2 via a snap-fit ​​structure, completely covering the outer opening of the lateral sliding cavity. An internal rubber sealing ring prevents dust intrusion. This structure effectively seals the installation space of the slider 6 and the elastic element 7, preventing external dust, oil, or corrosive media from entering the sliding cavity, thus avoiding jamming of the slider 6 or deterioration of the elastic element 7, and ensuring the long-term reliability and sensitivity of the locking mechanism.

[0018] Working Principle: When using this new type of weighing platform quick installation structure, firstly, the weighing platform is hoisted as a whole and aligned with the fixed base 1 pre-embedded in the concrete foundation. The conical guide sleeve 5 on the mounting plate 2 is aligned with the central positioning column 3 at the top of the fixed base 1. The platform is then slowly and vertically lowered. The conical guide sleeve 5 slides along the inverted conical guide surface of the central positioning column 3. Simultaneously, the slider 6 on the mounting plate 2 aligns with the L-shaped groove 4 on the fixed base 1 and enters its vertical guide section. As the platform continues to be pressed down, the slider 6 slides down the vertical guide section to the water... At the starting position of the horizontal locking section, the elastic element 7, which applies radial outward elastic force, pushes the slider 6 outward along the lateral sliding cavity of the mounting plate 2, causing the slider 6 to enter the horizontal locking section. The limiting pin 8 at the front end of the slider 6 rotates and slides along the horizontal locking section. When the slider 6 slides to the end of the horizontal locking section, the slot of the limiting pin 8 is fully engaged in the upper position of the arc-shaped stop 41, completing the locking action. Then the mounting plate 2 is fully in place, and the entire weighing platform is firmly fixed. Finally, it is confirmed that the sealing cover 9 is in a closed state, thus completing a series of operations.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
