Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, a rotating lever for a permanent magnet jack includes a main rod 2 installed at one end of a moving magnet rotating shaft 1 and having a rectangular cross section, and an accommodating groove 3 formed in the main rod 2 along a length direction of the main rod 2, the accommodating groove 3 being formed in a side surface of the main rod 2 away from the moving magnet rotating shaft 1, an edge of the accommodating groove 3 being flared, and the accommodating groove 3 communicating with an end surface of the main rod 2 away from the moving magnet rotating shaft 1; the rotating lever further comprises a rotating shaft 4 fixedly connected in the accommodating groove 3 and a secondary rod 5 which is arranged on the rotating shaft 4 in a sleeved mode in a rotating mode, the rotating shaft 4 is installed at one end, away from the rotating magnet rotating shaft 1, of the accommodating groove 3, and two ends of the rotating shaft 4 are fixedly connected with two opposite side walls of the accommodating groove 3 respectively. When the operator removes the permanent magnetism jack, can be with in inferior pole 5 screw in holding tank 3 to this reduces the whole length that rotates the lever, has reduced the probability that rotates lever and foreign object and take place to collide with. When the operator needs to rotate the moving magnet rotating shaft 1, the secondary rod 5 in the accommodating groove 3 can be rotated out, so that the whole length of the rotating lever is increased, the power arm is lengthened, and the operator can rotate the rotating lever more easily.
Referring to fig. 2, an installation groove 6 with a rectangular cross section is formed in one of the two opposite side walls of the accommodating groove 3, the installation groove 6 is formed in one end of the accommodating groove 3 far away from the rotating shaft 1 of the moving magnet (as shown in fig. 1), a clamping groove 7 which is rectangular and is also formed in one side surface of the secondary rod 5 facing the installation groove 6, the clamping groove 7 and the installation groove 6 are identical in specification and size, and when the secondary rod 5 is screwed out of the accommodating groove 3 and is parallel to the main rod 2, the clamping groove 7 is opposite to the installation groove 6. Sliding connection has and installs spring 9 with draw-in groove 7 joint complex fixture block 8 in mounting groove 6 between the tank bottom of fixture block 8 and mounting groove 6, spring 9 one end and fixture block 8 fixed connection, the spring 9 other end and the tank bottom fixed connection of mounting groove 6. One end of the clamping block 8, which is far away from the spring 9, is provided with a guide surface 10 which is in butt fit with the secondary rod 5, and the guide surface 10 is arranged on one side, back to the accommodating groove 3, of the clamping block 8. The main rod 2 is further provided with a separation component 11 for driving the clamping block 8 to separate from the clamping groove 7. When inferior pole 5 back-out holding tank 3 and be about to be parallel with mobile jib 2, fixture block 8 will compress spring 9 and automatic entering mounting groove 6 under the combined action of inferior pole 5 and spigot surface 10, when draw-in groove 7 on inferior pole 5 is just right to the time with mounting groove 6, spring 9 will drive in fixture block 8 gets into draw-in groove 7, and then locks the position of inferior pole 5, rotates the whole length of lever and lengthens. If the secondary lever 5 is rotated again, the operator drives the clamping block 8 to be separated from the clamping groove 7 through the separation component 11.
The separation component 11 comprises a pull rod 111 arranged on the main rod 2, one end of the pull rod 111 extends into the mounting groove 6 and is fixedly connected with the fixture block 8, the other end of the pull rod 111 extends out of the outer side wall of the main rod 2, and the separation component 11 further comprises a first pull ring 112 connected to one end of the pull rod 111, which penetrates out of the main rod 2. The operator's finger hooks the first pull ring 112 to pull the pull rod 111, so that the latch 8 is disengaged from the slot 7, and the position of the secondary lever 5 is unlocked, so that the secondary lever 5 can rotate again.
Referring to fig. 1 and 2, a magnet 12 is embedded in the accommodating groove 3, the magnet 12 is fixedly connected to one end of the accommodating groove 3 close to the rotating shaft 4 of the magnet 12, and a metal plate 13 which is matched with the magnet 12 in an attraction manner is embedded on the secondary rod 5. After the secondary rod 5 is screwed into the accommodating groove 3, the magnet 12 adsorbs the metal plate 13 on the secondary rod 5, so that the secondary rod 5 is locked, and the probability that the secondary rod 5 is screwed out of the accommodating groove 3 is reduced. In order to facilitate the operator to unscrew the secondary lever 5 from the receiving groove 3, a second pull ring 14 is fixedly connected to an end of the secondary lever 5 remote from the rotation shaft 4.
The implementation principle of the embodiment is as follows: when removing the permanent magnetism jack, the operator can be with inferior pole 5 screw in holding tank 3 in, after inferior pole 5 complete screw in holding tank 3, magnet 12 will adsorb the metal sheet 13 on inferior pole 5, reaches the effect of locking inferior pole 5 position to this reduces the overall length who rotates the lever, has reduced the probability that rotates lever and foreign object emergence and collide with. When the rotatory moving magnet pivot 1 of needs, the operator revolves out inferior pole 5 in the holding tank 3 through second pull ring 14, when inferior pole 5 revolves out holding tank 3 and be about to be parallel with mobile jib 2, fixture block 8 will compress spring 9 and automatic entering mounting groove 6 under the combined action of inferior pole 5 and spigot surface 10, draw-in groove 7 and mounting groove 6 on inferior pole 5 are just to the time, spring 9 will drive in fixture block 8 gets into draw-in groove 7, reach the effect of locking inferior pole 5 position, increase the overall length who rotates the lever with this, the power arm has been lengthened, make the operator can rotate the rotation lever more easily.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
