Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, in particular to an anti-bending pin shaft with a magnetic locking structure. Background Art

[0002] A pin is a type of standardized fastener that can be used for both static fixed connections and relative movement with the connected parts. It is mainly used at the hinged joints of two parts to form hinged connections. Pins are usually locked with cotter pins, which are reliable and easy to disassemble. In the prior art, in the locking structure of boxes, in order to facilitate the opening and locking of boxes, the pins are often inserted into the pin holes at the connection between the cover and the shell, or the cover and the shell are directly locked by the cooperation between the lock head and the hinge. In the process of transporting boxes, the edge of the box is generally fixed to the fixed box by fixing pins to ensure stability during transportation. However, locking the cover and the shell by simply inserting the pin into the pin hole can only play a locking role when the box is fixed. During the box transfer process, the cover and the shell cannot be kept in a locked state due to external factors such as vibration. At the same time, the box and the fixed box are fixedly connected by the fixing pin, which is not convenient for disassembly and assembly. Repeated disassembly and assembly will affect the tightness of the connection between the box and the fixed box. The lock method can only be opened with a special key, and it is more troublesome when the key is lost. Summary of the Invention

[0034] The bottom plate 24 of the housing 2 is fixed to facilitate the storage of items. The upper surface of the housing 2 is provided with a slot 25. The slot 25 is convenient for the sliding installation of the cover 11. The cover 11 is slidably inserted into the slot 25. At this time, the card column 12 slides into the arc groove 26. By rotating the handwheel 40, the handwheel 40 drives the rotating rod 39 to rotate, and the rotating rod 39 drives the small bevel gear 38 to rotate. The small bevel gear 38 is meshed with the large bevel gear 37 for transmission, so that the large bevel gear 37 drives the rotating column 36 to rotate, and the rotating column 36 drives the driving gear 35 to rotate.

At this time, the anti-bending pin 9 is slid into the socket 31, so that one end of the anti-bending pin 9 is in contact with the inside of the electric-controlled magnetic seat 10, and then the button box 27 is used to control the electric-controlled magnetic seat 10 to magnetically adsorb the anti-bending pin 9, thereby locking the anti-bending pin 9, thereby preventing the locking gear disc 8 from rotating at will. The locking between the cover 11 and the housing 2 is achieved by locking the gear disc 8, the anti-bending pin 9, the electric-controlled magnetic seat 10, and the clamping column 12.

[0035] During actual use, the button box 27 is used to control the rotation of the motor 13, and the motor 13 thereby drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the rotating disk 3 fixed at one end thereof to rotate.

The disk 8, the anti-bending pin 9, the electric-controlled magnetic seat 10, the clamping column 12, realize the locking between the cover 11 and the shell 2. When it is necessary to release the lock, the button box 27 is used to control the electric-controlled magnetic seat 10 to cancel the magnetic adsorption of the anti-bending pin 9, so that the anti-bending pin 9 can be pulled out through the pull ring 32. The hand wheel 40 is rotated in the opposite direction so that the locking toothed disk 8 no longer locks the clamping column 12, thereby facilitating the removal of the cover 11, thereby realizing the locking between the shell 2 and the cover 11 and the locking between the shell 2 and the fixed box 1, and also ensuring the stable locking between the shell 2 and the cover 11 and between the shell 2 and the fixed box 1 whether in transportation or at rest, thereby improving the practicality of the entire device.
