Detailed Description

The present application is described in further detail below with reference to figures 1-4.

The embodiment of the application discloses a heaven-center shaft. Referring to fig. 1, the zenith axis includes a connection part 1, a driving part 2, and a detachable assembly 3.

One side of connecting portion 1 is located to the 2 covers of drive division, and drive division 2 and the coaxial setting of connecting portion 1 are equipped with latch 21 in an organic whole on the outer peripheral lateral wall of drive division 2, and the quantity of latch 21 is a plurality of, and the setting of latch 21 along drive division 2's circumference is for the crank connection drive. The detachable assembly 3 is mounted on the connecting portion 1 and the driving portion 2 such that the connecting portion 1 and the driving portion 2 are fixed therebetween.

Referring to fig. 2, the detachable assembly 3 includes an external thread 31, an internal thread 32, a locking block 33, and a driving block 34. The male screw 31 is fixedly connected to an outer circumferential side wall of the connecting portion 1, and here, the male screw 31 is integrally provided on the connecting portion 1 as an example, and the male screw 31 is machined from the connecting portion 1. The internal thread 32 is fixedly connected to the inner circumferential side wall of the driving portion 2, where the internal thread 32 is integrally formed on the driving portion 2, for example, the internal thread 32 is machined from the driving portion 2, and the external thread 31 and the internal thread 32 are engaged so that the driving portion 2 can be screwed to the connecting portion 1.

Referring to fig. 3 and 4, an installation groove 11 is formed in an outer circumferential side wall of the connection portion 1, the locking block 33 is embedded in the installation groove 11 and slides in the direction of the installation groove 11, a locking groove 22 is formed in an inner side wall of the driving portion 2, and the locking block 33 extends out of the installation groove 11 and is inserted into the locking groove 22, so that the driving portion 2 is not prone to relative rotation with the connection portion 1. The driving block 34 is fixedly connected to the bottom of the mounting groove 11, the driving block 34 and the locking block 33 are both made of magnetic materials, and the driving block 34 and the locking block 33 are magnetically repelled, so that the locking block 33 moves to the side far away from the bottom of the mounting groove 11 under the action of the driving block 34. The locking block 33 is close to one side fixedly connected with guide post 331 of drive block 34, and guide post 331 is for non-magnetic material to make, is equipped with first through-hole 341 on the drive block 34, is equipped with second through-hole 12 on connecting portion 1, and when locking block 33 was close to drive block 34, guide post 331 passed first through-hole 341 and second through-hole 12 in proper order for difficult the rocking when locking block 33 moved along the length direction of guide post 331.

Referring to fig. 2 and 4, a side of the locking block 33 away from the driving block 34 has a guiding surface 332, the guiding surface 332 is located on a side of the driving block 34 opposite to a screwing direction of the driving part 2, such that a thickness of the locking block 33 gradually increases from the side away from the driving block 34 to the side close to the driving block 34, when the driving part 2 is screwed onto the connecting part 1, the driving part 2 forces the locking block 33 to retract into the mounting groove 11 through the guiding surface 332, and when the driving part 2 has a tendency to unscrew from the connecting part 1, a side of the locking block 33 away from the guiding surface 332 is engaged with a side wall of the locking groove 22, such that the locking block 33 is not easily inserted into the mounting groove 11 for unlocking.

Referring to fig. 2 and 4, a toggle block 333 is fixedly connected to the lock block 33, and here, the toggle block 333 and the lock block 33 are perpendicular to each other as an example. Be equipped with the hole 13 that slides on the lateral wall of mounting groove 11, the hole 13 that slides runs through connecting portion 1 and is close to the end wall of external screw thread 31, dials piece 333 and wears to establish and slides in the hole 13 that slides, and convenience of customers dials piece 333 through the operation and slides locking block 33. The toggle block 333 is flush with the end wall of the connecting part 1 away from the end wall of the locking block 33, so that the toggle block 333 is not easily moved by collision of an external object. One end of the toggle block 333, which is far away from the locking block 33, is provided with a holding surface 3331, the holding surface 3331 is located on one side of the toggle block 333, which is close to the outer circumferential side wall of the connecting part 1, so that a gap exists between the holding surface 3331 and the side wall of the sliding hole 13, and a user can insert fingers between the holding surface 3331 and the side wall of the sliding hole 13 to move the toggle block 333.

Referring to fig. 2 and 4, a sealing plate 334 is fixedly connected to a side of the toggle block 333 away from the holding surface 3331, where the sealing plate 334 is located at an end of the toggle block 333 away from the locking block 33, and when the toggle block 333 abuts against a side of the sliding hole 13 close to the outer circumferential sidewall of the connecting portion 1, the sealing plate 334 covers the sliding hole 13, so that impurities are not easy to enter the mounting groove 11 from the sliding hole 13, and the locking block 33 is not easy to retract into the mounting groove 11. Be equipped with the groove 14 that slides on the lateral wall that slides hole 13 kept away from mounting groove 11, the end wall of connecting portion 1 is run through to the groove 14 that slides, and shrouding 334 inlays to be established and slide and connect in the groove 14 that slides for difficult emergence is interfered between shrouding 334 and the lateral wall of the hole 13 that slides.

The implementation principle of a zenith axis in the embodiment of the application is as follows: when the latch 21 is worn and needs to be replaced, a finger is inserted between the holding surface 3331 and the side wall of the sliding hole 13 to toggle the toggle block 333, the locking block 33 retracts into the mounting groove 11, the worn driving part 2 is screwed out, and then a new driving part 2 is screwed on the connecting part 1 for replacement.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
