[0037] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present invention.
[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.
[0039] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be considered as part of the specification.
[0040] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.
[0041] An anti-dust cover structure provided by an embodiment of the present utility model, as Figure 1-8 shown, the anti-dust cover structure is rotatably arranged at the connection port of the connecting member 9. The anti-dust cover structure includes a cover body 1, a pivot portion 2 integrally formed with the cover body 1, and a rotating shaft installed inside the pivot portion 2. Two opposite pivot interfaces are provided on the connection port, namely a first pivot interface 91 and a second pivot interface 92. A rotating through hole 3 for installing the rotating shaft is axially penetrated inside the pivot portion 2. Two retaining rings are provided on the inner wall of the rotating through hole 3, namely a first retaining ring and a second retaining ring 41. The rotating shaft includes two shaft bodies, namely a first shaft body 5 and a second shaft body 7. A telescopic member 6 is provided between the two shaft bodies. The two shaft bodies and the telescopic member 6 are located between the two retaining rings, and the telescopic member 6 presses the two shaft bodies so that the two shaft bodies respectively abut against the corresponding retaining rings. Opposite outer side surfaces of the two shaft bodies extend to form two rotating shafts, namely a first rotating shaft 52 and a second rotating shaft 71. The two rotating shafts respectively pass through the corresponding retaining rings and are rotatably connected to the corresponding pivot interfaces. A complementary notch 51 and a protrusion 4 are axially formed between one of the shaft bodies and the corresponding retaining ring.
[0042] In this anti-dust cover structure, the shaft body and the rotating shaft can be driven by a tool to move into the rotating through hole 3, so as to release the rotational connection between the rotating shaft of the corresponding shaft body and the pivot interface, and further the anti-dust cover structure can be detached from the connecting member 9. Under the condition that the rotational connection can be normally realized, the anti-dust cover structure can be quickly disassembled, replaced, and assembled.
[0043] Furthermore, in order to facilitate the installation and disassembly of the shaft body, at least one notch 51 is provided on the outer periphery of one of the shaft bodies, and the corresponding retaining ring is a protrusion 4 provided on the inner wall of the rotating through hole 3 and having a shape corresponding to that of the notch 51. After the notch 51 and the protrusion 4 are in position corresponding, one of the shaft bodies enters the rotating through hole 3. By rotating the rotating shaft of one of the shaft bodies, the notch 51 and the protrusion 4 are axially misaligned and the outer end surface of one of the shaft bodies abuts against the inner end surface of the protrusion 4, thereby restricting one of the shaft bodies from detaching from the rotating through hole 3. Specifically, as Figure 2-7As shown, in this embodiment, a notch 51 is provided on the first shaft body 5, and the corresponding first retaining ring is composed of a protrusion 4, and two notches 51 and two protrusions 4 are provided and are symmetrically distributed relative to the axis. After the axial positions of the notch 51 and the protrusion 4 correspond, the first shaft body 5 enters into the rotating through hole 3, and by rotating the first rotating axis 52 of the first shaft body 5, the notch 51 and the protrusion 4 are axially misaligned and the outer end face of the first shaft body 5 abuts against the inner end face of the protrusion 4, thereby limiting the first shaft body 5 from being disengaged from the rotating through hole 3.
[0044] Further, for the installation of the second shaft 7, it is possible to install it into the rotating through hole 3 by hard interference from the first shaft 5 side of the rotating through hole 3 through the protrusion 4 until it abuts against the second retaining ring 41, and then assemble the telescopic member 6 and the first shaft 5 in sequence, such as Figure 6 , 7 As shown, this embodiment adopts this type of structure and assembly method.
[0045] It can be clearly understood that in other embodiments, the second shaft body can also be optionally provided with the same notch as the first shaft body, and then rotate into the rotating through hole through the protrusion from the first shaft body side of the rotating through hole until it abuts against the second retaining ring, and then the telescopic part and the first shaft body are assembled in sequence.
[0046] The telescopic member 6 is preferably a compression spring that is telescopic in the axial direction. In other embodiments, a retractable member with elasticity, such as a rubber block with appropriate elasticity, may also be selected.
[0047] Further, in order to facilitate the driving of the shaft, as Figure 2-4 As shown, in this embodiment, an operation opening 21 for exposing one of the shaft bodies, namely, the first shaft body 5, is axially arranged on the pivoting portion 2. By inserting a tool into the operation opening 21 and moving the first shaft body 5 into the rotating through hole 3, the first rotating shaft 52 can be withdrawn from the first pivot interface 91, and then the dust cover structure can be removed from the two pivot interfaces, so as to achieve the purpose of convenient and quick disassembly of the dust cover structure. When installing the dust cover structure, the second rotating shaft 71 can be rotatably connected with the second pivot interface 92 first, and then the tool can be inserted into the operation opening 21 and the first shaft body 5 can be moved into the rotating through hole 3. After the first rotating shaft 52 corresponds to the first pivot interface 91, the first shaft body 5 is released to reset, and then the first rotating shaft 52 is rotatably connected with the first pivot interface 91, and the installation of the dust cover structure is completed.
[0048] Furthermore, in order to ensure that the first rotating shaft 52 can smoothly exit the first pivot interface 91, in the axial direction, the distance between the end surface of the operation opening 21 away from the protrusion 4 and the inner end surface of the protrusion 4 is not less than the length of the rotating shaft of one of the shaft bodies extending out of the rotating through hole 3. Figure 6As shown, in this embodiment, the distance L1 between the end face of the operation port 21 away from the protrusion 4 and the inner end face of the protrusion 4 is equal to the length L2 of the first rotation shaft 52 of the first shaft body 5 extending out of the rotation through hole 3. In other embodiments, L1 may also be greater than L2, and the difference between L1 and L2 can be adjusted and determined according to the actual operation effect.
[0049] Further, in order to ensure that the shaft body can move and rotate smoothly within the rotation through hole 3 and facilitate the installation and disassembly of the shaft body, there is a clearance fit between the inner wall of the rotation through hole 3 and the outer peripheral surfaces of the two shaft bodies, and there is a clearance fit between the rotation shaft and the hole in the corresponding retaining ring. That is, there is a clearance fit between the outer peripheral surfaces of the first shaft body 5 and the second shaft body 7 and the inner wall of the rotation through hole 3, a clearance fit between the first rotation shaft 52 and the hole of the first retaining ring, and a clearance fit between the second rotation shaft 71 and the hole of the second retaining ring 41.
[0050] Further, in order to enable the cover body 1 to automatically return to its position to block the connection port after being opened, one of the retaining rings is arranged at the end of the rotation through hole 3, and the other is arranged within the rotation through hole 3 and divides the rotation through hole 3 into a first through hole 31 and a second through hole 32. The two shaft bodies and the telescopic member 6 are all located within the first through hole 31, and a torsion spring 8 is arranged within the second through hole 32. Specifically, as Figure 5 、 6 shown, in this embodiment, the first retaining ring is arranged at the end of the rotation through hole 3, the second retaining ring 41 is arranged within the rotation through hole 3 and divides the rotation through hole 3 into a first through hole 31 and a second through hole 32. The first shaft body 5 and the second shaft body 7 are both located within the first through hole 31, and the torsion spring 8 is arranged within the second through hole 32. The elastic torsional fit relationship between the cover body 1 and the connecting member 9 is realized through the torsion spring 8.
[0051] Specifically, the above-mentioned torsion spring 8 includes a spring body 81 and a first torsion arm 82 and a second torsion arm 83 connected to the spring body 81. One of the first torsion arm 82 and the second torsion arm 83 abuts against the pivot part 2, and the other abuts against the connecting member 9.
[0052] More specifically, a card slot 33 is provided on the inner wall of the second through hole 32, and the first torsion arm 82 is snapped into the card slot 33 to facilitate the abutment of the first torsion arm 82 against the pivot part 2 and the installation of the torsion spring 8. The second torsion arm 83 extends out of the second through hole 32 and abuts against the connecting member 9. Specifically, the connecting member 9 may be provided with structures such as grooves or insertion holes corresponding to the second torsion arm 83. The second torsion arm 83 entering the groove or insertion hole can achieve the abutment against the connecting member 9. This is a conventional structure and means in the art, so no detailed display and description are made.
[0053] Considering the convenience of assembly and the preferred environment for the operation of the torsion spring 8, the spring body 81 is coaxially arranged in the second through hole 32, and the rotation axis close to the second through hole 32, i.e., the second rotation axis 71, extends through the spring body 81 located in the second through hole 32 and then protrudes out of the second through hole 32.
[0054] Furthermore, in order to prevent the spring body 81 from obstructing the movement and rotation of the second rotation axis 71, a clearance fit is provided between the inner hole of the spring body 81 and the outer peripheral surface of the rotation axis close to the second through hole 32, i.e., the second rotation axis 71.
[0055] The above-mentioned connecting member 9 can be a connecting device with at least one connection port, such as a socket, an adapter, a connector, etc. In this embodiment, a discharge adapter is used as an illustration of the connecting member 9.
[0056] When specifically assembling the dust-proof cover structure, first, the second shaft body 7 and the second rotation axis 71 are inserted into the first through hole 31 from the side where the protrusion 4 is located until the second rotation axis 71 passes through the hole of the second retaining ring 41. Secondly, the telescopic member 6 is inserted into the first through hole 31 from the side where the protrusion 4 is located. Then, the notch 51 of the first shaft body 5 is aligned with the protrusion 4 and inserted into the first through hole 31. The first rotation axis 52 is rotated to axially displace the notch 51 and the protrusion 4. At this time, the first shaft body 5 and the second shaft body 7 are respectively pressed against the first retaining ring and the second retaining ring 41 under the extrusion of the telescopic member 6, and the first rotation axis 52 and the second rotation axis 71 respectively protrude out of the first through hole 31 and the second through hole 32. Finally, the torsion spring 8 is inserted into the second through hole 32 to complete the assembly of the dust-proof cover structure. The disassembly of the dust-proof cover structure can be carried out in reverse according to the above steps.
[0057] When installing the dust cover structure to the connection port of the connector 9, first slightly tilt the pivoting portion 2 to rotatably connect the second rotating shaft 71 with the second pivoting interface 92. At this time, the gap between the outer peripheral wall of the second rotating shaft 71 and the inner wall of the second pivoting interface 92 can be appropriately increased, or the second pivoting interface 92 can be presented as an appropriate flared structure, so that the second rotating shaft 71 can continue to be rotatably connected with the second pivoting interface 92 even when it is in an inclined posture not completely coaxially corresponding to the second pivoting interface 92. Then, insert a tool into the operation port 21 to drive the first shaft body 5 to move into the first through hole 31 until the first rotating shaft 52 retracts into the first through hole 31. At this time, the pivoting portion 2 can be correctly located between the first pivoting interface 91 and the second pivoting interface 92. Remove the tool to reset the first shaft body 5 and the first rotating shaft 52, and then the first rotating shaft 52 can be rotatably connected with the first pivoting interface 91 to complete the installation of the dust cover structure. When disassembling the dust cover structure from the connection port of the connector 9, open the cover body 1 to expose the operation port 21. Insert a tool into the operation port 21 to drive the first shaft body 5 to move into the first through hole 31 until the first rotating shaft 52 disengages from the rotational connection with the first pivoting interface 91 and retracts into the first through hole 31. At this time, move the pivoting portion 2 through the cover body 1 to tilt the pivoting portion 2 until the first rotating shaft 52 cannot be correspondingly connected to the first pivoting interface 91. Then, the tool can be removed and the dust cover structure can be taken off.
