The invention discloses a high-rigidity lock for quick connection. Wherein, it is formed by a frame, an inner support plate, a spring plate, a bottom plate, an eccentric wheel, and a spring; the frame and the bottom plate form one rectangle space with a round hole; said round hole contains one eccentric wheel; the front of spring plate is mounted with lock hooks that reversed bended; it is characterized in that: the inner support plate is at the middle of spring plate, while its two sides are supported by frame; the front of lock has one taper guide block. Compared with present technique, in said invention, the lock hook is supported on the inner support plate; the inner support plate is riveted on the frame; two sides of inner support plate bear symmetry forces, to support the lock hook and confirm enough rigidity; the guide block is taper, therefore, the lock hook can be easily inserted into the locked element.

The invention relates to an ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine solving the problems of service life influence and the like in the prior art. The ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine comprises a stand, a main shaft, a stator coil, a rotor sleeve, a rotor body, a traction wheel, a disc-type brake device and an encoder, wherein the main shaft is assembled on the stand; the rotor body, the traction wheel and the disc-type brake device are fixed on the rotor sleeve; and the encoder is assembled on the rear end of the main shaft. The invention puts a technical emphasis on that a machine base with a rear bearing and a front support with a front bearing are respectively fixed on both ends of the stand; the main shaft supports between the machine base and the front support through the front bearing and the rear bearing, and an internal circumference is attached to the rotor body of a permanent magnet and arranged outside the stator coil; the rotor sleeve is provided with a ventilation hole used for ventilation and heat dissipation and a dustproof rubber plug positioned on an outer sideend, and the rotor body, a brake disc and the traction wheel are respectively connected and fixed with the main shaft to form an integral type structure through the rotor sleeve. The invention has compact structure and design and reasonable stress distribution; and in addition, compared with a similar product, the ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine has the advantages of small occupying area, material saving, little energy consumption, high operation efficiency, safe and reliable use, convenient installation and maintenance, and the like.

The embodiment of the invention discloses a car table plate. The car table plate comprises a bottom plate for carrying a car and a supporting beam which is arranged on the side edge of the bottom plate and used for supporting the whole car table plate in a unilateral stress supporting mode, and the supporting beam and the bottom plate are integrally formed or fixedly connected. A guide portion is arranged on the supporting beam. The car table plate is unilaterally hung and supported through the supporting beam on the side edge, the structure is simple and firm, use is safe and reliable, and dismounting, mounting and replacing are convenient. The embodiment of the invention further discloses a three-dimensional parking device which comprises the car table plate, a stand column, a lifting mechanism, a horizontal moving mechanism, a rotary mechanism and a supporting guide mechanism. The supporting guide mechanism comprises a supporting sliding seat with a supporting portion, and the guide portion and the supporting portion are matched to enable the supporting beam to be movably arranged on the supporting sliding seat. The car table plate of the three-dimensional parking device is directly mounted on the supporting sliding seat in a hanging mode, the car table plate is even and stable in stress, safe and reliable to use and long in service life, the height of the car table plate away from the ground is small, the car can get on and off the car table plate conveniently, production cost is saved, and dismounting, mounting and replacing are convenient.

The invention discloses an external-installed triggering type anti-sink device. The external-installed triggering type anti-sink device comprises a base body with a lifting rail for guiding; a multi-claw rotor and a special-shaped clamp are rotatably installed in the base body through a pin shaft, a transmission part and a braking part which are in an L shape are installed on the special-shaped clamp, and the ends, close to the pin shaft, of the transmission part and the braking part are connected together, and the other ends of the transmission part and the braking part extend towards a distant place; an arc-shaped balance weight is formed by hunching up of the inner side face of the transmission part, an upper limiting plate used for limiting upwards rotating of the special-shaped clamp is formed on the position, corresponding to the outer side face of the transmission part, of the base body, and a side limiting face used for limiting downwards rotating of the special-shaped clamp is formed on the position, corresponding to the outer side face of the braking part, of the base body; and when the multi-claw rotor rotates, claws make sliding-matched movement along an arc-shaped track of the arc-shaped balance weight so that the special-shaped clamp can be pushed to deflect, and when the special-shaped clamp deflects to the outer side face of the transmission part and abuts against the upper limiting plate, the outer side face of the braking part abuts against the claws of the multi-claw rotor and limit rotation of the multi-claw rotor. According to the external-installed triggering type anti-sink device, the structure is simple and compact, and safety and reliability are high.
