Description

Technical Field

[0001] This utility model relates to the technical field of quick-release base support frame tools, and in particular to a base support frame that is easy to assemble and disassemble. Background Technology

[0002] In machining, equipment installation and various support scenarios, the base support frame is a key structure used to support and position components. Its stability and ease of assembly and disassembly directly affect the overall work efficiency. At present, traditional base support frames are mostly assembled with the base by bolt fixing, welding or simple snap-fit ​​connection.

[0003] While bolt fixing ensures connection strength, it requires precise alignment of bolt holes and individual tightening during installation, and tools are needed to loosen the bolts during disassembly, making the process cumbersome and time-consuming. Welding provides a stable connection but lacks flexibility for assembly and disassembly, making it difficult to adapt to component replacement or repositioning needs. Some simple snap-fit ​​structures, due to unreasonable snap-fit ​​component design, often suffer from insufficient positioning accuracy and difficulty in controlling snap-fit ​​force. In practical applications, especially in scenarios requiring frequent disassembly and assembly of the support frame (such as production line changes and equipment maintenance), these structural defects of traditional support frames lead to complex assembly and disassembly processes: during installation, the snap-fit ​​blocks and positioning structure are difficult to align quickly, often requiring repeated adjustments to achieve effective snap-fit; during disassembly, the snap-fit ​​components are prone to jamming due to uneven force, sometimes requiring external force to pry them open, increasing operational difficulty and potentially causing component wear due to violent disassembly, severely impacting assembly and disassembly efficiency and failing to meet the demands for quick and convenient assembly and disassembly in practical work. Therefore, these problems need to be addressed. Utility Model Content

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

[0021] Example: See Figure 1-5 This utility model discloses a base support frame for easy assembly and disassembly, comprising a base 1, through which a fixing platform 2 is easily installed; multiple equidistant fixing platforms 2 are horizontally fixed to the top surface of the base 1, through which a support frame 3 is easily installed; the upper end of the fixing platform 2 is snapped with the support frame 3, through which the parts to be placed are easily placed; and snap-fit ​​components are installed in the base 1 and the fixing platforms 2, and mating components are installed in the support frame 3.

[0022] The snap-fit ​​assembly includes a cylindrical snap-fit ​​cavity 4 and a mounting groove 5 formed along the axis of the inner cavity of the fixed platform 2, and a cylindrical first spring-loaded cavity 6 formed along the inner cavity of the base 1. Two equidistant driving cavities 7 are formed at the front and rear ends of the snap-fit ​​cavity 4, facilitating the installation of a limiting plate 8. A limiting plate 8 is installed in the opposite ends of the driving cavities 7, facilitating the limiting of the abutment plate 11 and thus restricting the snap-fit ​​rod 9. The opposite ends of the driving cavities 7 are connected to the snap-fit ​​cavity 4, and the bottom end of the mounting groove 5 is coaxial with and connected to the snap-fit ​​cavity 4. A snap-fit ​​rod 9 is longitudinally slidably installed in the driving cavity 7, facilitating the installation of the snap-fit ​​block 10, the abutment plate 11, and the torsion block 18. Snap-fit ​​blocks 10 are installed on the opposite end faces of both snap-fit ​​rods 9, facilitating the snap-fit ​​of the support frame 3. A contact plate 11 is fixedly connected to the front end of the connecting rod 9; the contact plate 11 facilitates the limiting plate 8 to limit the locking rod 9; a torsion block 18 is installed at the far end of the two locking rods 9, which mainly facilitates manual stretching when the locking rod 9 is locked, and secondly facilitates the limiting of the locking rod 9; and a drive spring 12 is sleeved on the outside of the locking rod 9, which facilitates the driving force for the locking rod 9; the locking block 10 is semi-circular in shape and has a trapezoidal cross-section, and the trapezoidal slope of the locking block 10 has rounded corners. The rear end face of the contact plate 11 abuts against the front end face of the limiting plate 8, the front end and rear end face of the drive spring 12 abut against the front end face of the inner cavity of the drive cavity 7 and the front end face of the limiting plate 8, respectively, and the rear end faces of the two torsion blocks 18 abut against the front end and rear end face of the fixed platform 2.

[0023] In this invention, a first spring 20 is vertically mounted in the first spring cavity 6, which provides driving force to the support plate 19 by abutting against it. The support plate 19 is slidably mounted on the upper end of the first spring cavity 6, allowing the driving force provided by the first spring 20 to resist the weight of the support frame 3 and the items supported by it. The mating components include a positioning block 13 mounted on the lower end of the support frame 3, which facilitates the engagement of the locking block 10 to limit the position of the support frame 3. The positioning block 13 is circular with an inverted trapezoidal cross-section, and the trapezoidal slope of the positioning block 13 has rounded corners. A second spring cavity 14 is formed inside the support frame 3, facilitating the movement of a second spring 16. Moving grooves 15 are formed at both the front and rear ends of the second spring cavity 14, allowing the sliding installation of the limiting spring block 17. A second spring is vertically mounted inside the second spring cavity 14. 16. The second spring 16 facilitates the provision of driving force for the spring block 17; the spring block 17 is slidably installed in the moving groove 15. The spring block 17 is cylindrical, and both the upper and lower ends of the spring block 17 are rounded. The spring block 17 facilitates the removal of the support frame 3 by cooperating with the snap-fit ​​block 10 and the positioning block 13; the bottom end of the moving groove 15 is located on the top surface of the positioning block 13, and the upper end of the second spring spring 16 abuts against the bottom surface of the spring block 17. The lower end abuts against the top surface of the positioning block 13. The bottom surface of the snap-fit ​​block 10 installed in the snap-fit ​​assembly abuts against the top surface of the positioning block 13 installed in the mating assembly. The slope of the snap-fit ​​block 10 and the rounded corner of the spring block 17 are provided with corresponding rounded corners. The bottom surface of the positioning block 13 abuts against the top surface of the support plate 19 in the snap-fit ​​assembly. The spring force of the first spring spring 20 in the snap-fit ​​assembly and the mating assembly is greater than that of the drive spring 12. The spring force of the drive spring 12 is greater than that of the second spring spring 16.

[0024] Working principle: When this utility model is used, the base 1 and the fixed platform 2 are placed at the set position in the process flow. This product will be divided into the installation process and the disassembly process of the support frame 3.

[0025] Installation process: After the base 1 and the fixed platform 2 are installed, insert the support frame 3 through the installation slot 5 opened at the top of the fixed platform 2 (the support frame 3 moves in the snap-fit ​​cavity 4 and the installation slot 5 plays a guiding and limiting role for the support frame 3). The positioning block 13 installed at the bottom of the support frame 3 presses against the snap-fit ​​block 10. The snap-fit ​​block 10 is subjected to outward pressing force, which is passed through the abutment plate 11 fixed to the outside of the snap-fit ​​rod 9 to press against the drive spring 12 (the snap-fit ​​rod 9 will also move outward under the limitation of the drive cavity 7, and the operator can visually see the outward movement of the reverse twist block 18). When the positioning block 13 abuts against the support plate 19, the bottom surface of the snap-fit ​​block 10 will be driven by the drive spring 12 and snap onto the top of the positioning block 13 (the operator will hear a "click", which is also produced by the abutment plate 11 being hit by the drive spring 12 and the limiting plate 8). This indicates that the support frame 3 is installed and the sample to be placed can be placed on the support frame 3.

[0026] Disassembly procedure: After the sample placed on the upper part of the support frame 3 is used up, remove the sample and press the support frame 3 down forcefully. The positioning block 13 at the lower end of the support frame 3 will squeeze the support plate 19 (thereby squeezing the first spring 20), causing the positioning block 13 to continue to move down in the first spring cavity 6. When the spring block 17 squeezes the snap-fit ​​block 10, the bottom surface of the snap-fit ​​block 10 will continue to move down and snap onto the top surface of the spring block 17 (after hearing a "click" sound). The operator can then lift the support frame 3. During the lifting process, the snap-fit ​​block 10 will drive the spring block 17 to resist the second spring spring 16 installed in the second spring cavity 14 and move down in the moving groove 15. When the bottom end of the spring block 17 abuts against the top end of the positioning block 13, it will continue to move up, forcing the snap-fit ​​block 10 to squeeze the drive spring 12 and slide down along the rounded corner on the surface of the spring block 17. At this time, the support frame 3 can be removed (at this time, all snap-fit ​​components and mating components will be reset by their respective installed spring structures).

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
