As shown in fig. 4, the locking unit includes a connecting block 14, and two rows of protruding nails are provided on a middle portion of one surface of the connecting block 14. On both sides of the opening 13 of the sheath 1 a row of through holes 15 is provided, respectively. The width of the two rows of through holes 15 on the sheath 1 is the same as the width of the two rows of convex nails on the connecting block 14. The interval between every row of convex pins on the connecting block 14 is consistent with the interval between every row of through holes 15 on the sheath 1. Thus, when the studs on the connecting block 14 are manually aligned with the through holes 15 on the sheath 1, the studs on the connecting block 14 are manually snapped into the through holes on the sheath 1, thus closing the openings 13 on the sheath 1. The technical effect of further fixing the protective device on the shelf upright post 16 is achieved.

The method comprises the following specific operations: when the protective device is used, firstly, the protective sleeve 1 is sleeved on the rack upright post 16 through the opening 13 on the protective sleeve 1, and the first buffer mechanism of the protective device is aligned to the direction, which is easy to be impacted, of the rack upright post 16. Through mutual butt joint of two butt joint boards 12 and goods shelves stand 16 of buckle unit, realized that preliminary sheath 1 fixes on goods shelves stand 16 like this. Two rows of studs on the connecting block 14 are manually aligned with the through holes 15 on both sides of the opening 13 of the sheath 1, and the studs on the connecting block 14 are manually pressed down into the through holes 15 on both sides of the opening 13. The connecting piece 14 thus completes the closure of the opening 13 in the sheath 1 and serves to further reinforce the sheath 1 and prevent the sheath 1 from sliding off the shelf post 16.

When the impact force acts on the protection device, the impact force acts on the first buffer mechanism firstly, the sheath 1 and the transverse plate 2 are correspondingly extruded and abutted, and the first air bag 3 enhances the delaying and weakening treatment on the impact force, so that the first buffer mechanism realizes the dispersing and reducing treatment on the impact force. The sheath 1 stretches out in the corresponding follow sheath 1 of extension board 7 when being extruded, and the aluminium foil luminescent layer on the extension board 7, strong striking effect of flashing reaches around the suggestion of personnel on the spot alert, and protector is suffering the striking and is destroying. When the transverse plate 2 is pressed, the rack plate 9 on the transverse plate 2 correspondingly moves downwards, the rack plate 9 enables the first gear 8 to rotate, and the pawl 18 correspondingly pushes the ratchet wheel 19 once when the first gear 8 rotates.

When the first gear 8 rotates, the first gear 8 drives the second gear 21 to rotate correspondingly, the second gear 21 rotates to enable the rotating shaft 20 to rotate correspondingly, and the rotating shaft 20 rotates to enable the magnet ring fixedly arranged on the rotating shaft 20 to rotate correspondingly. This scheme is through utilizing magnetism to give birth to electric principle, and the magnet circle is at the pivoted in-process, and the fixed coil that sets up around the magnet circle generates electricity, and the coil generates electricity and makes bulb 17 light. In the scheme, the kinetic energy of the counting unit when the first gear 8 rotates is utilized, so that the bulb 17 on the extension plate 7 is lightened. Thus, the extension plate 7 can more clearly and more comprehensively remind people around the protection device, and the protection device is damaged and needs to be prevented by taking measures in time.

After the first buffer mechanism finishes the treatment of the impact force, the rest impact force is continuously transmitted to the second buffer mechanism, and the second air bag 5 and the third air bag 6 in the two hollow semicylinders 4 and the two sloping plates respectively carry out further dispersion, reduction and weakening treatment on the rest impact force until the impact force is treated on the protection device.

In this scheme, protector can carry out dispersion treatment, subduct the processing many times to the impulsive force for the protector collision avoidance of this scheme is effectual. Make the protector of this scheme resist the ability reinforce of impact force through addding first gasbag 3, second gasbag 5 and third gasbag 6 in this scheme, the protection field effect at goods shelves stand 16 is showing. This scheme is through setting up the warning unit, when protector is by the striking, can play good warning, warning effect, and simple structure is ingenious, and it is effectual to warn. This scheme is once struck through setting up the count unit, and the automatic count of accomplishing of count unit is once struck every time protector, and the number on the teeth of a cogwheel that ratchet 19 is close to pawl 18 can directly be looked over when the number of times that protector is struck need be looked over like this to protector's in service behavior. Utilize first gear 8 pivoted kinetic energy in the count unit in this scheme, utilize magnetism to give birth to electric principle, the magnet circle rotates, and the coil generates electricity to make bulb 17 light, reach the technological effect of warning of more omnidirectional through bulb 17.
