DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-16The embodiment of the present invention provides a gear-shifting motor installation docking mechanism, which is used to connect the gear-shifting motor 16 with the electrical equipment, including: a docking seat 1, a sliding ring 3, a docking plate 5, a sleeve 7 and an inner tube 8. The docking seat 1 is fixedly connected to the housing of the electrical equipment, and the docking seat 1 has a plug-in slot 2; the sliding ring 3 is slidably connected in the plug-in slot 2, and the sliding ring 3 is radially slidably connected with a plurality of locking rods 4 distributed in an annular shape; the docking plate 5 is fixedly connected to the housing of the gear-shifting motor 16, and a plurality of docking slots 6 distributed in an annular shape are opened on it; the sleeve 7 and the tapping switch of the electrical equipment are connected to each other. The inner tube 8 is elastically spirally connected in the sleeve 7; in the process of the docking plate 5 on the gear-shifting motor 16 squeezing the sliding ring 3 and entering the plug-in slot 2: the transmission assembly drives each locking rod 4 to slide and close to lock and match with each docking slot 6 one by one and lock through the locking member, wherein each locking rod 4 can lock the docking plate 5 of the gear-shifting motor 16 on the sliding ring 3 to achieve the effect of locking and installing the gear-shifting motor 16, and the output shaft 161 of the gear-shifting motor 16 is docked and inserted into the special-shaped docking shaft hole 11 on the inner tube 8 to match with the tap switch. It should be noted that the tap switch is a prior art, and the tap switch has a knob-type gear for gear shifting, based on which the sleeve 7 is coaxially fixedly connected with the knob-type gear. It should be noted that the output shaft 161 of the gear-shifting motor 16 includes a rotating shaft and a protruding block arranged on the rotating shaft, and the shape of the special-shaped docking shaft hole 11 is adapted to the output shaft 161 of the gear-shifting motor 16. The plug-in slot 2 also has an opening for the gear-shifting motor 16 to pass through. It should be noted that, in the process of locking the docking plate 5, in a preferred state, the output shaft 161 of the gear-shifting motor 16 just docks with the docking shaft hole 11 of the inner tube 8. In a normal state, the output shaft 161 of the gear-shifting motor 16 will force the inner tube 8 to rotate and slide relative to the sleeve 7 until the output shaft 161 of the gear-shifting motor 16 is aligned with the docking shaft hole 11, and the output shaft 161 of the gear-shifting motor 16 is inserted into the docking shaft hole 11 under the action of elasticity. It should be noted that the docking shaft hole 11 can preferably have a plurality of holes that match the output shaft 161, so that the inner tube 8 can better and faster drive the output shaft 161 to align with the docking shaft hole 11 and be stuck into the docking shaft hole 11 when the inner tube 8 elastically spirally slides in the sleeve 7, which improves the practicality to a certain extent.

[0034] Specifically, during the installation process, the output shaft 161 of the gear-adjusting motor 16 is passed through the openings in the sliding ring 3 and the plug-in slot 2 in turn, and at the same time, each docking slot 6 of the docking plate 5 is docked with each locking rod 4 one by one and passed through the docking slot 6. Then, the docking plate 5 needs to be driven to press the sliding ring 3 so that the sliding ring 3 slides in the plug-in slot 2 to move away from the notch of the plug-in slot 2, and in the sliding process, the transmission assembly is used to drive each locking rod 4 to slide radially relative to the sliding ring 3 to close and lock the docking plate 5, and after the locking is completed, the sliding ring 3 is automatically locked by the locking member, thereby completing the locking of the gear-adjusting motor 16; and in the process of locking the docking plate 5, the inner tube 8 in the sleeve 7 is elastically spirally connected to cooperate with each other, so that the output shaft 161 of the gear-adjusting motor 16 can be inserted into the docking shaft hole 11 without manual adjustment, which reduces the installation difficulty to a certain extent; in summary, during the entire installation process, there is no need to use a mechanical docking method connected by flange bolts, the operation steps are simple, the time spent is short, and the work intensity of the staff is reduced to a certain extent.

[0035] Among them, the transmission assembly includes a plurality of transmission units 9 corresponding to each locking rod 4 one by one, and each transmission unit 9 includes: a transmission gear 91, a first rack 92 and a second rack 93, the transmission gear 91 is rotatably connected to the sliding disk; the first rack 92 is fixedly connected to the docking seat 1, and the first rack 92 is meshed with the transmission gear 91; the second rack 93 is fixedly connected to the corresponding locking rod 4, and the transmission gear 91 is meshed with the second rack 93; when the sliding ring 3 is squeezed by the docking disk 5 and enters the plug-in slot 2, the first rack 92 drives the transmission gear 91 to rotate so that the second rack 93 slides along the radial direction of the sliding ring 3. It should be noted that the length direction of each first rack 92 is the vertical direction, and each first rack 92 is parallel to the axis of the sliding ring 3, while the length direction of each second rack 93 is the horizontal direction, and each second rack 93 slides along the radial direction of the sliding ring 3, and the first rack 92 and the second rack 93 located on the same transmission gear 91 are staggered to prevent the first rack 92 and the second rack 93 from interfering with each other when meshing with the transmission gear 91. The sliding ring 3 is provided with a plurality of through-port chute corresponding to each locking rod 4, and each locking rod 4 is a connected vertical section and a horizontal section, the vertical section includes a portion located in the through-port chute and a portion passing through the through-port chute and connected to the horizontal section, and the height of the portion of the vertical section passing through the through-port chute is consistent with the thickness of the docking plate 5. At this point, it can be known that when the lower surface of the docking plate 5 abuts against the upper surface of the sliding ring 3, the upper surface of the docking plate 5 is flush with the lower surface of the horizontal section of the locking rod 4, which is convenient for locking the docking plate 5 during the subsequent closing process of each locking rod 4. It should be further explained that a limiting groove is provided on the inner wall of the through-port chute, and the part of the vertical section located in the through-port chute is fixedly connected to a limiting protrusion located in the limiting groove, which is convenient for each locking rod 4 to slide radially along the sliding ring 3 in the corresponding through-port chute.

[0036] Specifically, during the process of compressing the sliding ring 3, the docking plate 5 can drive each transmission gear 91 to move downward relative to the plug-in slot 2, and then drive each transmission gear 91 to engage with the corresponding first rack 92 to rotate each transmission gear 91, and each rotating transmission gear 91 can engage with the corresponding second rack 93 to make the second rack 93 fixedly connected to the corresponding locking rod 4 slide and close along the radial direction of the sliding ring 3, thereby achieving the purpose of each locking rod 4 locking the docking plate 5.

[0037] Among them, the sleeve 7 is provided with a spiral groove 12, the inner tube 8 is fixedly connected with a slider 13 located in the spiral groove 12, and the sleeve 7 is provided with an elastic telescopic rod 14, and one end of the elastic telescopic rod 14 is fixedly connected to the bottom end of the sleeve 7, and the other end is rotatably connected to the bottom of the inner tube 8. Specifically, when the output shaft 161 of the gear-shifting motor 16 abuts against the inner tube 8, the slider 13 on the inner tube 8 will slide along the spiral groove 12, and the inner tube 8 will rotate and move downward relative to the sleeve 7 until the output shaft 161 of the gear-shifting motor 16 is aligned with the docking shaft hole 11 on the inner tube 8, and finally the inner tube 8 is driven to move up and rotate during the process of the elastic telescopic rod 14 restoring its deformation. It should be noted that the inner tube 8 will drive the output shaft 161 of the gear-shifting motor 16 to rotate during the upward movement and rotation of the inner tube 8. Based on this, when the output shaft 161 of the gear-adjusting motor 16 rotates, the slider 13 abuts against the sleeve 7 to drive the sleeve 7 to rotate to adjust the knob-type gear position, that is, to complete the gear position adjustment of the tap switch.

[0038] Among them, as a preferred embodiment of the present invention, a guide slot is provided on the sleeve 7, which includes a connected vertical slot 15 and a spiral slot 12, a slider 13 located in the guide slot is fixedly connected to the inner tube 8, and an elastic telescopic rod 14 is provided in the sleeve 7, and one end of the elastic telescopic rod 14 is fixedly connected to the bottom end of the sleeve 7, and the other end is rotatably connected to the bottom of the inner tube 8. Specifically, when the output shaft 161 of the gear-shifting motor 16 abuts against the inner tube 8, the slider 13 first slides vertically along the vertical slot 15 of the guide slot to the spiral slot 12, and then the slider 13 slides along the spiral slot 12, so that the inner tube 8 rotates and moves downward relative to the sleeve 7 until the output shaft 161 of the gear-shifting motor 16 is aligned with the docking shaft hole 11 on the inner tube 8, and finally the inner tube 8 is driven to move upward and rotate during the process of the elastic telescopic rod 14 restoring the deformation, and finally the slider 13 slides from the spiral slot 12 to the vertical slot 15. Based on this, when the output shaft 161 of the gear-adjusting motor 16 rotates, the slider 13 will abut the sleeve 7 to drive the sleeve 7 to rotate to adjust the knob-type gear position, that is, to complete the gear adjustment of the tap switch; and the output shaft 161 of the gear-adjusting motor 16 can rotate in both directions to adjust the knob-type gear position, thereby achieving a better adjustment effect.

[0039] The locking member includes a plurality of locking units 10 distributed on the docking seat 1 in a circumferential array, each locking unit 10 includes: a first wedge block 101, a first elastic member 102, a positioning tube 103, a second wedge block 106 and a third wedge block 107, the first wedge block 101 is radially slidably connected to the sliding ring 3; the first elastic member 102 drives the first wedge block 101 to slide radially along the sliding ring 3 to move away from the axis of the sliding ring 3 during the process of restoring elastic deformation; the positioning tube 103 is fixedly connected to the docking seat 1, and an unlocking rod 104 is slidably connected therein, and a first spring 105 is sleeved on the unlocking rod 104, and one end of the first spring 105 is fixedly connected to the unlocking rod 104, and the other end is fixedly connected It is connected to the positioning tube 103; the second wedge block 106 is connected to the plug-in slot 2 by radial sliding along the plug-in slot 2, and the second wedge block 106 is fixedly connected to the unlocking rod 104; the third wedge block 107 is fixedly connected to the inner wall of the plug-in slot 2, the inclined surface of the third wedge block 107 is consistent with the inclination of the inclined surface of the second wedge block 106, and the inclined surface of the first wedge block 101 abuts against the inclined surface of the third wedge block; in the process of the sliding ring 3 being squeezed by the docking plate 5 and entering the plug-in slot 2, the first wedge block 101 abuts against the third wedge block 107 to slide along the radial direction of the sliding ring 3, and then the second wedge block 106 is engaged with the first wedge block 101 under the drive of the first spring 105. It should be noted that the first elastic member 102 includes a slide bar and a second spring, the slide bar is slidably connected to the slide ring 3, and the second spring is sleeved on the slide bar, one end of the second spring is fixedly connected to the slide bar, and the other end is fixedly connected to the slide ring 3, the inner rod of the slide bar is fixedly connected to the first wedge block 101, and limit slide bars are provided on both sides of the slide bar, and the two limit slide bars are slidably connected to the slide ring 3. It should also be noted that the elastic force of the second spring to restore the elastic deformation is preferably greater than the elastic force of the first spring 105 to restore the elastic deformation, so that the inclined surface of the first wedge block 101 can always be slidably abutted with the inclined surface of the third wedge block 107, and under the cooperation of the first elastic member 102 and the first spring 105, the inclined surface of the first wedge block 101 will abut against the inclined surface of the second wedge block 106. It should be noted that a first linear groove is opened on the inner wall of the positioning tube 103 , a first protrusion is fixedly connected to the unlocking rod 104 , and the first protrusion is located in the first linear groove, so that the unlocking rod 104 can move linearly in the positioning tube 103 .

[0040] Specifically, during the process of the docking plate 5 on the gear shifting motor 16 squeezing the sliding ring 3 and entering the plug-in slot 2: each first wedge block 101 on the sliding ring 3 abuts and slides along the inclined surface of the third wedge block 107 to make the first wedge block 101 slide radially along the sliding ring 3 until the first wedge block 101 is located below the second wedge block 106. At this time, the first spring 105 drives the corresponding second wedge block 106 to approach the axis of the sliding ring 3 during the process of restoring the deformation, thereby achieving a snap-fit ​​with the first wedge block 101, thereby preventing the sliding of the sliding ring 3 and completing the locking work.

[0041] The other end of the unlocking rod 104 passes through one end of the positioning tube 103 and is rotatably connected to a rotating block, to which a pull rod 17 is fixedly connected. The positioning tube 103 is provided with a notched slide groove for the pull rod 17 to slide. Specifically, when unlocking, the pull rod 17 is manually pulled to make the pull rod 17 slide in the notched slot and disengage from the notched slot, and then the rotating block is rotated to make the pull rod 17 misaligned with the notched slot to limit the first spring 105 from driving the second wedge block 106 to reset, thereby affecting the subsequent disassembly of the gear shifting motor 16; in this process, each unlocking rod 104 slides linearly in the positioning tube 103 to make the corresponding second wedge block 106 move away from the axis of the sliding ring 3 until the second wedge block 106 disengages from the first wedge block 101, and then in the process of disassembling the gear shifting motor 16 to make the docking plate 5 disengage from the plug-in slot 2, the first elastic member 102 drives the inclined surface of the first wedge block 101 to slide along the inclined surface of the third wedge block 107 when restoring the elastic deformation to make the sliding ring 3 move up and close to the notch of the plug-in slot 2. This process facilitates each locking rod 4 to lock the docking plate 5 of the gear shifting motor 16 when reinstalling the gear shifting motor 16. At this point, the gear shifting motor 16 can be disassembled better and more conveniently in the process, the operation steps are simple, the time spent is short, and the work intensity of the staff is reduced to a certain extent.
