In this embodiment, the top of the rotating base 301 is provided with a cross-shaped slot, so that the rotating base can rotate quickly by using the existing tools (screwdriver, etc.).
When the rotating assembly 8 is stirred after the bottom shell 1 and the cover plate 2 are assembled, the infrared receiving and sending mechanism 5 and the USB mechanism 4 are driven to extend out of the bottom shell 1 through the adjusting assembly 7 and the moving assembly 6 respectively, and the rotating assembly 8 is continuously stirred and the infrared receiving and sending mechanism 5 and the USB mechanism 4 are driven to withdraw the bottom shell 1 through the adjusting assembly 7 and the moving assembly 6 respectively. When infrared mechanism 5 that receives stretches out the back backward and stir rotating assembly 8 in following drain pan 1, can cooperate adjusting part 7 to drive infrared mechanism 5 that receives and send out and rotate along drain pan 1, rotate the in-process orientation and change and then can guarantee infrared effect of receiving and sending out.
Referring to fig. 1 to 5, in the present embodiment, it is preferable that: the rotating assembly 8 comprises a shifting block 801 which is in rotating fit with the bottom shell 1 and is in key shaft type assembly with the stud 302, a part of the shifting block 801 protrudes out of the bottom shell 1 to facilitate rotation of the shifting block 801, and when the shifting block 801 is rotated, the stud 302 can be driven to rotate synchronously and the stud 302 can ascend and descend based on the shifting block 801. A double flywheel 802 movably attached to the adjusting assembly 7 and the moving assembly 6 and movably clamped with the rotating base 301 is arranged above the shifting block 801, no connection relation exists between the double flywheel 802 and the shifting block 801, when the shifting block 801 drives the stud 302 to rotate, the stud 302 can drive the rotating base 301 to synchronously rotate, and the rotating base 301 drives the double flywheel 802 to synchronously rotate, so that the shifting block 801 can be synchronous with the double flywheel 802 during rotation; meanwhile, the bottom of the double flywheel 802 is attached to the top of the stud 302, and when the stud 302 rises relative to the shifting block 801, the double flywheel 802 can be driven to rise synchronously.
Specifically, the dual flywheel 802 includes an upper cam 8021 and a lower cam 8022 which are fixedly connected up and down, the bottom of the lower cam 8022 abuts against the top of the stud 302, a pawl 803 is rotatably mounted inside the upper cam 8021 through a rotating shaft and a torsion spring (not shown in the figure), a ratchet 303 movably engaged with the pawl 803 is fixedly mounted on the outer surface of the rotating base 301, the upper cam 8021 can be driven to ascend by the pawl 803 when the ratchet 303 rotates clockwise, and the pawl 803 can contract and the upper cam 8021 does not move when the ratchet 303 rotates counterclockwise. Since the stud 302 can drive the upper cam 8021, the lower cam 8022 and the pawl 803 to ascend, the ratchet 303 is provided with a certain length along the axial direction of the rotating base 301, so that the pawl 803 does not disengage from the ratchet 303 when ascending.
It should be noted that although the bottom of the lower cam 8022 abuts against the stud 302, the lower cam 8022 and the upper cam 8021 have an initial height in the bottom case 1, and specifically, a step may be formed in the bottom case 1 for the lower cam 8022 and the dial 801 to be seated. That is, when the stud 302 ascends, the stud 302 can drive the upper cam 8021 and the lower cam 8022 to ascend synchronously, but when the stud 302 descends, the upper cam 8021 and the lower cam 8022 cannot descend any more.
In the above structure, the orientations of the upper cam 8021 and the lower cam 8022 are vertically arranged, the upper cam 8021 is oriented left and right, the lower cam 8022 is oriented front and back, the upper cam 8021 and the lower cam 8022 are movably attached to the moving assembly 6 and the adjusting assembly 7 respectively, and at this time, the moving assembly 6 and the adjusting assembly 7 enable the USB mechanism 4 and the infrared transceiver 5 to be in a contracted state respectively; when the upper cam 8021 and the lower cam 8022 rotate synchronously, the USB mechanism 4 and the infrared transceiver 5 can be extended from the bottom case 1 to be in an extended state by the moving assembly 6 and the adjusting assembly 7, respectively.
Further, the adjusting assembly 7 includes a first ejector rod 702 which is in sliding fit with the inner bottom wall of the bottom case 1 in a left-right direction and movably attached to the lower cam 8022, a support rod 701 fixedly connected with the infrared hair extension and extension mechanism 5 is rotatably sleeved inside the first ejector rod 702, the support of the infrared hair extension and extension mechanism 5 is realized through the support rod 701, and the first ejector rod 702 can drive the infrared hair extension and extension mechanism 5 to move synchronously through the support rod 701 when moving left and right; meanwhile, a first spring 704 is fixedly installed between the right side of the first push rod 702 and the inner wall of the bottom case 1, and is used for automatic resetting of the first push rod 702 after moving under the action of the lower cam 8022. The top of the support rod 701 is further fixedly provided with a connecting rod 703 corresponding to the position of the upper cam 8021, when the infrared hair mechanism 5 is in a contracted state, the connecting rod 703 is located on the right side of the upper cam 8021 and is in a staggered state, when the infrared hair mechanism 5 is in an extended state (i.e., after left shifting), the connecting rod 703 is located at a corresponding position above the upper cam 8021, and at this time, if the upper cam 8021 rises under the action of the stud 302, the connecting rod 703 is pushed to deflect counterclockwise.
Specifically, a slope 705 is formed at the end of the connecting rod 703 close to the upper cam 8021, so that when the upper cam 8021 ascends, the connecting rod 703 and the strut 701 can be pushed by the slope 705 to deflect counterclockwise; when the infrared hair-waving mechanism 5 is in the contracted state, the link 703 and the slope 705 are both located on the left side of the upper cam 8021, and at this time, even if the upper cam 8021 is raised, no contact occurs with the slope 705. In order to realize the automatic reset after the deflection of the strut 701, a torsion spring (not shown in the figure) is further sleeved on the outer surface of the strut 701, and the torsion spring can move left and right along with the strut 701 and keep the left and right horizontal corresponding states of the strut 701, the connecting rod 703 and the infrared hair extension mechanism 5.
In the structure, the periphery of the outer surface of the bottom case 1 is provided with the fillets, and the arrangement position of the support rod 701 in the bottom case 1 corresponds to the circle center of the upper left fillet, namely the support rod 701 is completely coincided with the upper left fillet of the bottom case 1 when drawing a circle by taking the support rod 701 as the circle center; at this time, when the supporting rod 701 drives the infrared hair extension mechanism 5 to deflect counterclockwise, the extension state (the extension distance is unchanged) in the bottom case 1 can be ensured, and the hair extension effect is further ensured. Meanwhile, an avoiding hole 101 for the infrared receiving and sending mechanism 5 to deflect is formed in the surface of the bottom shell 1 in a penetrating mode, and interference caused by the fact that the infrared receiving and sending mechanism 5 deflects after extending is avoided.
Further, the moving assembly 6 includes a second push rod 601 sliding fitted to the inner bottom wall of the bottom case 1 in a front-back manner and fixedly connected to the USB mechanism 4, the rear end of the second push rod 601 is movably attached to the upper cam 8021, the second push rod 601 is located below the connecting rod 703, and a second spring 602 is fixedly installed between the front surface of the second push rod 601 and the inner bottom wall of the bottom case 1, so as to achieve automatic resetting of the second push rod 601 after moving under the action of the upper cam 8021.
In this embodiment, the USB mechanism 4 and the infrared transceiver 5 are vertically extended and retracted relative to the bottom case 1; in an initial state, the USB mechanism 4 and the infrared receiving and sending mechanism 5 are both in a contraction state relative to the bottom shell 1, so that the whole body is convenient to carry, and the collision and damage caused by the protruding of the USB mechanism 4 and the infrared receiving and sending mechanism 5 are avoided; when in use, the USB mechanism 4 and the infrared receiving and sending mechanism 5 can be adjusted to be in an extending state relative to the bottom shell 1, so as to realize infrared receiving and sending signals and data export.
In this embodiment, a boss 102 for the stud 302 to be screwed is formed on the inner bottom wall of the bottom case 1 in an upward protruding manner, when the rotating base 301 starts to rotate, the stud 302 descends relative to the boss 102 and the rotating base 301, so as to relatively fix the bottom case 1 and the cover plate 2, and when the rotating base 301 rotates in a reverse direction, the stud 302 ascends relative to the boss 102 and the rotating base 301, so as to quickly separate the bottom case 1 from the cover plate 2. And when bottom shell 1 and apron 2 assemble, can rotate several rings in reverse for the rotation regulation of follow-up shifting block 801 after stud 302 locks (namely clockwise rotation arrives the position).
In the above structure, the boss 102, the dial 801, the stud 302 and the rotary base 301 are arranged at the center of the rounded corner at the upper right of the bottom case 1, and the portion of the dial 801 protruding out of the bottom case 1 can be homogenized, that is, the area of the dial 801 protruding out of the bottom case 1 is uniform, and meanwhile, the arrangement of the stud 302 and the rotary base 301 and the detachable connection of the bottom case 1 and the cover plate 2 are not affected.
When the universal serial bus connector is used, the dial block 801 is rotated clockwise to drive the stud 302 to rotate synchronously, so that the stud 302 descends relative to the boss 102 and the rotating base 301, the stud 302 can drive the rotating base 301 to rotate clockwise, the rotating base 301 drives the upper cam 8021 and the lower cam 8022 to rotate clockwise through the ratchet 303 and the pawl 803, the first ejector rod 702 drives the support rod 701 and the infrared receiving and sending mechanism 5 to extend out of the bottom case 1 and stretch the first spring 704, the second ejector rod 601 drives the USB mechanism 4 to extend out of the bottom case 1 and extrude the second spring 602, and finally the USB mechanism 4 is inserted into an external terminal and the infrared receiving and sending mechanism 5 is started to receive and send signals. In actual use, the bottom shell 1 can be attached to an external terminal, an opening of the bottom shell 1 corresponding to the USB mechanism 4 corresponds to the external terminal, and the bottom shell 1 and the external terminal are in a butting state; then, the dial 801 is rotated clockwise to extend the USB mechanism 4 from the bottom case 1, and the USB mechanism 4 is automatically inserted into the external terminal due to the abutting state when the USB mechanism is extended, thereby simplifying the operation steps.
When the first top rod 702 drives the infrared transceiver 5 to extend out of the bottom case 1, the connecting rod 703 is driven to move left synchronously, so that the connecting rod 703 is located right above the upper cam 8021 (at this time, the dial block 801 needs to be rotated 90 degrees clockwise, the infrared transceiver 5 and the USB mechanism 4 are both in an extended limit state, a cross groove at the top of the rotating base 301 can be observed in the rotating process, the dial block 801 rotates 90 degrees clockwise, and then the cross groove not only plays a role in driving the rotating base 301 to rotate by subsequent matching with a screwdriver, but also plays a role in prompting the rotation angle of the dial block 801), and at this time, the upper cam 8021 and the lower cam 8022 are respectively converted into a front-back orientation state and a left-right orientation state. Then, the stud 302 is driven by the reverse rotation of the shifting block 801 to ascend relative to the cam and the rotating seat 301, the stud 302 can push the upper cam 8021 and the lower cam 8022 to ascend synchronously in the ascending process, when the upper cam 8021 and the lower cam 8022 ascend in a front-back orientation state and a left-right orientation state respectively, the stud cannot be separated from the second ejector rod 601 and the first ejector rod 702, and meanwhile, the upper cam 8021 can push the connecting rod 703 and the infrared receiving and sending mechanism 5 to swing anticlockwise in the ascending process, so that the infrared receiving and sending mechanism 5 keeps an extending state and adjusts the orientation, and further, the signal receiving and sending effect is ensured.
In summary, by the matching of the structures such as the shifting block 801, the stud 302, the double flywheel 802 and the support rod 701, when the shifting block 801 is rotated clockwise, the infrared transceiver 5 and the USB mechanism 4 can be switched back and forth between the retracted state and the extended state, when the infrared transceiver 5 is in the extended state, the shifting block 801 is rotated counterclockwise, the infrared transceiver 5 can be driven to deflect and adjust the orientation, the signal transceiver effect of the infrared transceiver 5 can be ensured, and the extended state of the infrared transceiver 5 cannot be affected; and when the infrared hair-sending mechanism 5 and the USB mechanism 4 are in a contraction state, the portable USB flash disk can be conveniently carried, and the problems of collision and the like caused when the infrared hair-sending mechanism and the USB mechanism protrude out of the bottom shell 1 are avoided. The whole scheme is combined with the arrangement of the locking part 3, the relative fixation of the bottom shell 1 and the cover plate 2 cannot be influenced, and the operation steps are matched with the clockwise rotation tightening and the anticlockwise rotation loosening of the locking part 3; with retaining member 3 and shifting block 801 setting in the upper right side of drain pan 1 for USB mechanism 4 stretches out from the below and pegs graft with external terminal, has made things convenient for shifting block 801 to rotate the use, can also make things convenient for the grafting of USB mechanism 4 after offsetting drain pan 1 and external terminal, holistic practicality is higher.
Example two:
referring to fig. 1 to 8, on the basis of the first embodiment, in order to avoid other people from easily detaching the bottom case 1 and the cover plate 2, the infrared transceiver 5 and the USB mechanism 4 are stolen; an edge 304 is fixedly installed on the outer surface of the rotating seat 301, a key groove 306 for the edge 304 to slide is formed in the stud 302, and the rotating seat 301 and the stud 302 are detachably connected through the edge 304 and the stud 302. The surface of the edge 304 is provided with a clamping groove 305, a sliding component 9 corresponding to the clamping groove 305 is arranged between the shifting block 801 and the lower cam 8022, and the sliding component 9 is in a rising state relative to the shifting block 801 in an initial state.
When the sliding assembly 9 is in a raised state, it is movably engaged with the engaging slot 305, and the stud 302 drives the lower cam 8022 to make the sliding assembly 9 abut against the engaging slot 305 when the stud 302 is raised, and the stud 302 can not be raised any more and is blocked, so that the rotating base 301 is also locked and the bottom case 1 and the cover plate 2 can not be detached. When the sliding assembly 9 is in a descending state, the sliding assembly is separated from the clamping groove 305, the stud 302 is not limited when ascending, and the rotating base 301 can normally rotate counterclockwise to separate the bottom case 1 from the cover plate 2.
Referring to fig. 1 to 9, in the present embodiment, it is preferable that: the sliding assembly 9 comprises a lantern ring 901 which is sleeved on the outer surface of the dial block 801 in an up-and-down sliding manner and a sliding block 902 which is in horizontal sliding fit with the lower cam 8022, a support 903 corresponding to the sliding block 902 is fixedly installed on the surface of the lantern ring 901 and located inside the dial block 801, a third spring 904 is fixedly installed between the bottom of the support 903 and the inside of the dial block 801, the support 903 has a tendency of moving upwards under the action of the third spring 904, and the lantern ring 901 is in a rising state relative to the dial block 801 in an initial state. A fourth spring 905 is fixedly mounted between the end of the slider 902 far from the edge 304 and the lower cam 8022, and the slider 902 has a tendency to move toward the edge 304 under the action of the fourth spring 905. When the bracket 903 is manually pressed downwards, the sliding block 902 can be driven to contract inwards the lower cam 8022, so that the sliding block 902 is separated from the clamping groove 305 on the edge 304, and the integral limit of the stud 302 is released.
Specifically, as shown in fig. 8, a placement groove 10 is commonly formed between the dial 801 and the lower cam 8022 for allowing the slider 902 to horizontally slide left and right and the holder 903 to slide up and down, and the collar 901 is disposed outside the placement groove 10 and can block the placement groove 10, so that the placement groove 10 is not visible when the dial 801 is viewed from the outside. The lantern ring 901 is formed by connecting an upper circular ring and a lower circular ring with a middle vertical section, and the placing groove 10, namely the corresponding vertical section, is formed and blocked by the placing groove; when the collar 901 is in a raised state relative to the dial 801, it is located just in the middle of the outer surface (up and down) of the dial 801.
In the above structure, the opposite ends of the support 903 and the slider 902 are provided with a slope 906, the surface of the slider 902 is provided with a wedge-shaped groove 907 matched with the slope 906, when the support 903 descends, the slider 902 can be driven to horizontally retract into the lower cam 8022 through the slope 906 and the wedge-shaped groove 907, and when the support 903 is above, the slider 902 can move towards the edge 304 (i.e. extend out of the lower cam 8022) under the action of the fourth spring 905.
During the use, clockwise rotation shifting block 801 makes infrared receiving and dispatching mechanism 5 and USB mechanism 4 stretch out from drain pan 1, and reverse rotation shifting block 801 drives infrared receiving and dispatching mechanism 5 anticlockwise swing afterwards for infrared receiving and dispatching mechanism 5 keeps stretching out the state and adjusts the orientation, and this part working process and effect are the same with in embodiment one, and it is unnecessary here to describe repeatedly. The difference lies in that: before the dial block 801 and the dial block 801 are rotated clockwise and anticlockwise, the lantern ring 901 needs to be pressed downwards relative to the dial block 801, so that the lantern ring 901 drives the support 903 in the dial block 801 to descend, the support 903 can drive the sliding block 902 to be separated from the clamping groove 305 through the inclined surface 906 and the wedge-shaped groove 907, and at the moment, the limitation on the stud 302 is relieved, so that the clockwise/anticlockwise rotation can be normally realized. After the infrared hair-sending mechanism 5 and the USB mechanism 4 are reset into the bottom case 1, the lantern ring 901 and the bracket 903 are reset in sequence by loosening the lantern ring 901 under the action of the third spring 904, at this time, the slider 902 moves towards the edge 304 direction and is clamped with the clamping groove 305 under the action of the fourth spring 905, and at this time, the stud 302 is blocked by the butting of the clamping groove 305 and the slider 902 when rising relative to the boss 102, so that the stud 302 cannot be separated from the boss 102 and further cannot be separated from the bottom case 1 and the cover plate 2. In the above structure, the set collar 901 can be used when the dial block 801 is rotated, so that the friction force contacting with the hand can be effectively increased, and the smooth rotation of the collar 901 is further ensured.
In the first embodiment, the infrared transceiver 5 and the USB mechanism 4 can be driven to extend out from the bottom case 1, and the infrared transceiver 5 can be kept in an extended state and adjusted in orientation; but arbitrary personnel all can drive double-screw bolt 302 and boss 102 separation through instrument (bottle opener etc.), and then can realize that the infrared quick dismantlement of receiving mechanism 5 and USB mechanism 4 in drain pan 1 for the stolen risk greatly increased of infrared receiving mechanism 5 and USB mechanism 4 has certain use limitation.
Compare in embodiment one, through the cooperation of slider 902, the lantern ring 901, draw-in groove 305 and structures such as lower cam 8022, all need to push down lantern ring 901 contact spacing to double-screw bolt 302 before shifting block 801 clockwise/anticlockwise rotates, can realize the limited spacing to double-screw bolt 302 again automatically when wholly not using, under the condition that other personnel are not knowing, can't make double-screw bolt 302 and boss 102 separation when rotating seat 301 through the instrument rotation, and then make bottom shell 1 and apron 2 unable separation, can effectively reduce the stolen risk of infrared hair extension mechanism 5 and USB mechanism 4, and guaranteed the relative fixed reliability between bottom shell 1 and the apron 2. When the stud 302 is limited, the lantern ring 901 is located in the middle of the outer surface of the shifting block 801, the design enables the stud to look normal from the outside and not to be easily suspected, the risk of theft can be further reduced, meanwhile, the lantern ring 901 can increase friction, the smooth rotation of the shifting block 801 is guaranteed, and the design of increasing friction is not needed any more; the whole scheme is combined with the arrangement of the shifting block 801 and the key shaft type assembly of the stud 302 and the rotating seat 301, the movement of the stud 302 driving the lower cam 8022 is not influenced, and the applicability is stronger.
Example three:
referring to fig. 1 to 10, on the basis of the second embodiment, in order to improve the overall experience of use, a groove is formed on the outer surface of the shifting block 801, and a cross bar 12 corresponding to the position of the lantern ring 901 is elastically connected to the inside of the groove through a fifth spring 11; when the collar 901 is in a raised state relative to the dial 801 (i.e., located in the middle of the outer surface of the dial 801), the collar 901 abuts against the end of the cross bar 12 away from the fifth spring 11 and presses the fifth spring 11, and when the collar 901 is in a lowered state relative to the dial 801 (i.e., when the collar 901 is pressed down relative to the dial 801), the cross bar 12 can extend out of the groove and abut against the surface of the collar 901 under the action of the fifth spring 11, at this time, the collar 901 cannot rise any more, and it is necessary to manually retract the cross bar 12 into the dial 801 before the collar 901 can rise and return.
Referring to fig. 1 to 10, in the present embodiment, it is preferable that: the horizontal pole 12 corresponds with the ring below the lantern ring 901, and the right-hand member of horizontal pole 12 offsets with the inner wall of below ring during the rising state, and the bottom of horizontal pole 12 offsets with the top of below ring during the decline state to this realization is spacing effectively to the lantern ring 901.
Meanwhile, as the stud 302 is in a limited state in the ascending state and the cross rod 12 can be just blocked, the cross rod 12 cannot be seen when the stud 302 is limited, and further the movement of the lantern ring 901 cannot be imagined, so that the risk of being stolen can be further reduced.
When the infrared hair extension mechanism is used, the collar 901 is pressed down, the shifting block 801 is rotated clockwise, the infrared hair extension mechanism 5 and the USB mechanism 4 are extended out, then the collar 901 is pressed down, the shifting block 801 is rotated reversely, the infrared hair extension mechanism 5 is driven to swing anticlockwise, the infrared hair extension mechanism 5 is enabled to keep an extended state and the orientation is adjusted, the working process and the effect of the part are the same as those in the second embodiment, and repeated description is omitted here. The differences are that: when the lantern ring 901 is pressed down, the cross rod 12 can be exposed, under the action of the fifth spring 11, the cross rod 12 extends out of the shifting block 801 and abuts against the lantern ring 901, so that the lantern ring 901 cannot rise automatically after being pressed down, and at the moment, the shifting block 801 can freely rotate clockwise/anticlockwise; after the cross rod 12 is pushed to be retracted into the shifting block 801, the collar 901 can be automatically reset under the action of the third spring 904.
In the second embodiment, the stud 302 can be limited and the risk of theft can be reduced when the anti-theft lock is not used, but the collar 901 needs to be pressed down before the dial block 801 is rotated clockwise/counterclockwise, so that the overall operation steps are increased, the experience is reduced, and certain use limitation exists.
Compared with the second embodiment, through the matching of the structures of the shifting block 801, the lantern ring 901, the cross rod 12 and the like, after the lantern ring 901 is pressed down, the cross rod 12 can extend out to abut against the lantern ring 901, so that the lantern ring 901 cannot automatically reset, and further, the shifting block 801 can freely rotate clockwise/anticlockwise; when the cross rod 12 and the lantern ring 901 are reset, the lantern ring 901 can block the cross rod 12, when the shifting block 801 is seen from the outside, only the lantern ring 901 in the middle of the shifting block 801 is still arranged, and safety is not easy to be doubted; meanwhile, the cross rod 12 also has the effect of positioning the initial position of the shifting block 801, when the cross rod 12 faces a certain direction and is located outside the bottom case 1, that means that the shifting block 801 is approximately located at the initial position before rotation. The whole scheme is combined with the movement of the lantern ring 901, the subsequent reset of the lantern ring 901 cannot be influenced, and more requirements in practical use are met.
