Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, a wire winder with a control knob at a plug includes a winding portion, a cable 1, and a plug assembly. The winding part comprises a base 2, a rotary cylinder 3, a locking cover 4, an electric brush, a rotary joint 5 and a lifting cylinder 6. The top of the base 2 is provided with a circular boss 9. The bottom of the rotary cylinder 3 and the circular boss 9 on the base 2 form a revolute pair. A winding spring is arranged between the rotating cylinder 3 and the base 2 and used for providing winding force after the cable is pulled out.
The brush comprises a brush ring 7 and a contact 8. The brush ring 7 is fixed at the bottom of the inner side surface of the rotating cylinder 3. The contact 8 is fixed on one side of the top of the circular boss 9 and is in contact with the brush ring 7, so that power transmission is realized. The metal contacts on the contact 8 are respectively connected with the metal rings on the brush ring 7, so that the power transmission of two-phase power or three-phase power is realized. A support table is fixed on the top of the circular boss 9. A rotary joint 5 is arranged at the center of the support platform. The rotary joint 5 has a rotary portion and a stationary portion. The rotating part and the static part form a revolute pair and are provided with liquid-passing joints. The liquid joint intercommunication that leads to on rotating part and the static portion realizes hydraulic drive. The lifting cylinder 6 is arranged on the static part of the rotary joint 5; the inner cavity of the lifting cylinder 6 is square; a piston lifting rod is connected in the lifting cylinder 6 in a sliding way. The top end of the piston lifting rod is fixed with the center position of the locking cover 4. Because the inner cavity of the lifting cylinder 6 and the piston lifting rod are both square, the locking cover 4 can only slide up and down and cannot rotate.
The lock cover 4 is located directly above the rotary cylinder 3. The bottom of the locking cover 4 and the corresponding position of the top of the rotating cylinder 3 are provided with a ring of locking teeth 10. When the locking cover 4 is lifted up so that the locking cover 4 is separated from the locking teeth 10 on the rotary cylinder 3, the rotary cylinder 3 can rotate freely; when the lock cover 4 is lowered so that the lock cover 4 is engaged with the lock teeth 10 on the rotary cylinder 3, the rotary cylinder 3 cannot be rotated under the restriction of the lock cover 4.
The cable 1 is wound on the outer side of the rotating cylinder 3, and the end part of the inner end of the cable is fixed with the rotating cylinder 3. The cable 1 is internally provided with a transmission line 1-1 and a hydraulic line 1-2 which are isolated from each other. The driving liquid is arranged in the hydraulic line 1-2. The outside of the hydraulic line 1-2 is wrapped with a braided layer for limiting expansion. The power transmission line 1-1 penetrates out from the inner end of the cable 1 and is connected to the brush ring 7 to realize two-phase or three-phase power transmission, and the hydraulic line 1-2 penetrates out from the inner end of the cable 1 and is connected to a liquid passing joint of a rotating part of the rotary joint 5.
The outer end of the cable 1 is connected to a plug assembly. The plug assembly comprises a housing 11, a socket, a control cylinder and a button 12. The socket is mounted at the outer end of the housing 11 and is shaped to correspond to a socket for the outside. The control cylinder is mounted in the housing 11. A control piston rod is connected in the control cylinder in a sliding way. The outer end of the control piston rod extends out of the housing 11 and is fixed with the button 12. The power line 1-1 in the cable 1 is connected to the socket. The hydraulic lines 1-2 in the cable 1 are connected to the control cylinders. When the button 12 is pressed, the control piston rod extrudes the driving liquid in the control cylinder, the driving liquid in the control cylinder is extruded, the pressure is transmitted into the lifting cylinder 6 through the hydraulic line 1-2, the locking cover 4 is pushed to be lifted to be separated from the rotating cylinder 3, and the unlocking of the rotating cylinder 3 is realized at the moment. When the button 12 is released, the button 12 bounces under the action of the spring, the driving liquid is pressurized and returns to the control cylinder through the damping hole, the driving liquid in the lifting cylinder 6 is discharged and descends, and the locking cover 4 descends under the action of self gravity to lock the rotating cylinder 3.
As a preferred solution, the inner cavity of the control cylinder 13 is directly connected to the outside through a safety valve 14, as shown in fig. 3. The purpose of the relief valve 14 is that when the hydraulic pressure is too high, the relief valve 14 can automatically be introduced into the atmosphere to prevent the hydraulic cylinder from bursting due to the excessive hydraulic pressure. An oil filter 15 and a damping pipe 16 are connected in series at the position of the hydraulic line 1-2 close to the rotary joint 5; the damping tube 16 stabilizes the flow velocity of the driving liquid; the screen filter 15 is used to filter the drive liquid clean to ensure that the drive liquid entering the lift cylinder 6 is free of impurities.
The working principle of the invention is as follows:
when a user needs to pull out the cable, the button 12 is pressed down, so that the locking cover 4 is lifted under the action of oil pressure; at the moment, the user only needs to pull the plug assembly to pull out the cable; in the process of pulling out the cable, the rotating cylinder 3 rotates forwards to drive the winding spring to accumulate elastic potential energy.
When the length of the cable reaches the requirement, the button 12 is released, and the locking cover 4 moves downwards to be locked with the rotating cylinder 3; at this time, the rotary drum 3 cannot be rotated continuously, and the length of the cable can be maintained.
When the user needs to recover the cable, the button 12 is pressed down, so that the locking cover 4 is lifted under the action of oil pressure; the winding spring drives the rotating cylinder to rotate reversely, so that the cable is wound on the rotating cylinder again.
Example 2
As shown in fig. 4, the present embodiment is different from embodiment 1 in that: the inner cavity of the lifting cylinder 6 and the piston lifting rod are both cylindrical. A plurality of guide posts 17 are vertically arranged on the base. The side edges of the locking cover 4 are provided with guide holes corresponding to the guide posts 17. The locking cover 4 forms a sliding pair with the guide post 17 through the guide hole, thereby improving the reliability of locking the rotary drum.
