Description

Technical Field

[0001] The utility model relates to a flip cover mechanism with the function of quick installation and disassembly. Background Art

[0002] At present, many shaft design and assembly methods use a structural design method that directly designs the shaft structure on the plastic, and uses force to assemble it. This is a conventional assembly method, which usually requires the plastic shaft wall to be deformed before insertion, and it must be ensured that the entire machine will not fall off easily when it falls. This requires the shaft to be inserted very deeply and the shaft wall to be greatly deformed. This assembly method is extremely difficult to disassemble and is not conducive to replacement.

[0026] Furthermore, the technical solutions of the various embodiments of the present invention may be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in the field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] The utility model provides a cover flipping mechanism with the function of quick installation and disassembly.

[0028] like Figure 1-6 As shown, the flip mechanism with quick installation and disassembly provided by the embodiment of the utility model includes a face cover 10, a cover plate 20 and a shaft component 30 connected between the face cover 10 and the cover plate 20, the shaft component 30 includes a flip shaft 31, a snap ring 32 and a connecting spring 33, the face cover 10 and the cover plate 20 are connected through the flip shaft 31, the snap ring 32 is snapped on the flip shaft 31, one end of the connecting spring 33 is supported on the face cover 10, and the other end is connected to the snap ring 32, so that the flip shaft 31 is always connected between the face cover 10 and the cover plate 20 when the connecting spring 33 is not squeezed by external force.

[0029] In this embodiment, when the cylindrical flip-cover shaft 31 is not subjected to external force, the connection between the face cover 10 and the cover plate 20 can be maintained so that the cover plate 20 can be freely flipped on the face cover 10. When removing the cover plate 20, the connection spring 33 can be squeezed by loading external force onto the flip-cover shaft 31 to disconnect the flip-cover shaft 31 and realize the removal of the cover plate 20, thereby solving the technical problem that the current cover plate 20 is difficult to remove.

[0030] The cover plate 20 is provided with a flip cover connecting hole 21 located on the side, and a receiving cavity 22 is formed from the outer end surface of the flip cover connecting hole 21 to be recessed inward to receive part of the flip cover shaft 31. The face cover 10 includes a receiving cavity 11, and the clamping plate and the connecting spring 33 are both arranged in the receiving cavity 11. The outer surface of the receiving cavity 11 is provided with an insertion hole 12 for inserting the flip cover shaft 31. In this embodiment, when the cover plate 20 is not installed on the face cover 10, the top cover and the bottom cover of the face cover 10 are first opened to expose the receiving cavity 11, and then the connecting spring 33 is installed and the flip cover shaft 31 is installed. The clamping plate is clamped on the flip cover shaft 31, and at this time, the flip cover shaft 31 is partially exposed from the insertion hole 12 (such as Figure 4 As shown), external force can be applied to the flip cover shaft 31 to compress the flip cover shaft 31 inwardly, and the face cover 10 can be slid in at this time. Since the flip cover shaft 31 is compressed by the end surface of the face cover 10, even if the external force is removed, the face cover 10 will press against the flip cover shaft 31, and then by moving the cover plate 20, when the flip cover shaft 31 is aligned with the accommodating cavity 22, the flip cover shaft 31 will extend into the accommodating cavity 22 and clamp the flip cover, thereby completing the installation of the flip cover, and the cover plate 20 can be freely flipped on the face cover 10.

[0031] In addition, the cover plate 20 is provided with a supporting groove, which is in communication with the accommodating cavity 22, so that an external force can be applied to the flip cover shaft 31 through the supporting groove to disconnect the flip cover shaft 31 from the accommodating cavity 22. Therefore, when disassembling the cover plate 20, an external force can be applied to the flip cover shaft 31 from the supporting groove (the external force applied during disassembly and assembly can be applied by tweezers) to press the flip cover shaft 31 into the accommodating cavity 11. At this time, the flip cover shaft 31 and the cover plate 20 are disconnected, and the cover plate 20 can be slid out to achieve disassembly. It is understandable that please refer to Figure 6 The card plate is in an E-shape as a whole, and has a holding position 321 for being held on the second column 312 and a notch 322 communicating with the holding position 321 at the axis of the card plate. The notch 322 can be used to install the flip cover shaft 31, and the entire outer edge of the card plate will be stuck in the cavity 11, so that even if the flip cover shaft 31 is pressed into the cavity 11 and then the external force is removed, when it is restored to its original state, the flip cover shaft 31 will still extend from the insertion hole 12.

[0032] In the above embodiments, please refer to Figure 5 The flip cover shaft 31 includes a first column 311, a second column 312 and a third column 313 connected to each other. The diameter of the second column 312 is smaller than that of the first column 311 and the third column 313. The clamping plate is clamped on the second column 312 and contacts the inner wall surface of the cavity 11. The end of the flip cover shaft 31 is located inside the accommodating cavity 22. In this embodiment, since the diameter of the second column 312 is small, after the second column 312 is fixed to the clamping position 321 through the notch 322, the stability and guidance can be effectively improved.

[0033] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
