The specific embodiment

As Fig. 1, Fig. 3 and shown in Figure 4: a kind of protecting of the present invention blocked, comprise that the adjacent Connection Block that is provided with, Connection Block comprise upper connecting base 2 and lower connecting base 3 every blocking 1 between blocking 1, also be provided with auxiliary tube 4 between upper connecting base 2 and lower connecting base 3, be provided with in auxiliary tube 4 and take off post 41; Upper connecting base 2 comprises button 21, the upper rotating seat 22 with internal gear, the first spring 23, cog 24 and with rotatable hopper 25, the first springs 23 of internal gear with cog and 24 be placed in the first cavity 251 of rotatable hopper 25; Making under the first spring 23 elastic force effects cogs 24 is meshed with the internal gear of upper rotating seat 22, the internal gear of rotatable hopper 25 respectively.The second cavity 252 of rotatable hopper 25 is provided with rivet 26 and pad 27, and pad 27 is fixed on and prevents in the second cavity 252 that rivet 26 from falling down from the second cavity 252.Auxiliary tube 4 upper ends are inserted in the second cavity 252, and the projection 211 of button 21 stretches in the second cavity 252, and rivet 26 lower ends 41 are in contact with one another with taking off post.

Lower connecting base 3 comprises lower rotating seat 31 with internal gear, the second spring 32, lower gear 33 and with the base 34 of internal gear; The second spring 32 and lower gear 33 are arranged in the cavity of lower rotating seat 31 and base 34 formation, and lower gear 33 is meshed with the internal gear of lower rotating seat 31, the internal gear of base 34 respectively.

41 upper ends that take off post are socketed with the 3rd spring 28, the three spring 28 upper ends and suppress on pad 27, and suppress in auxiliary tube 4 upper ends the lower end; Take off post and 41 be provided with bulge loop 411 and lower convex ring 412; Between lower convex ring 412 and auxiliary tube 4 diapires, the 4th spring 42 is installed, the interior pipe close 43 that can contact with upper bulge loop 411 of fixing of auxiliary tube 4, pipe close 43 act on bulge loop 411 and prevent from taking off post and 41 deviate from from auxiliary tube 4.

Button 21 has four back-offs 212 that snap onto rotating seat 22, and projection 211 is socketed with the 5th spring 29, the five spring 29 upper ends and suppresses on button 21, and suppress on upper rotating seat 22 lower end.

Lower rotating seat 31 is provided with the groove 311 that holds auxiliary tube 4, and lower rotating seat 31 also is provided with guiding breach 312, and guiding breach 312 is connected with groove 311.In the time will pulling down auxiliary tube 4, only need apply thrust upwards to auxiliary tube 4, auxiliary tube 4 lower ends just can be deviate from from groove 311, then outwards move back from guiding breach 312, so just can make auxiliary tube 4 lower ends from lower rotating seat 31 separation; Auxiliary tube 4 upper ends are deviate from from the second cavity 252 of rotatable hopper 25, thereby pull down auxiliary tube 4.

Folding or regulate when the angle of blocking between 1, only need push button 21, will make cogs 24 is not meshed with upper rotating seat 22 internal gears, the projection 211 of button 21 pushes rivets 26 simultaneously, rivet 26 acts on and takes off post on 41, taking off post 41 moves down and drives lower gear 33 and move down lower gear 33 is not meshed with lower rotating seat 31 internal gears, thereby makes adjacent two every blocking 1 rotation relatively; Also may be folded on (as shown in Figure 4) together.

Unclamp button 21, cog and 24 reset under the first spring 23 effect, recover to be meshed with upper rotating seat 22 internal gears, lower gear 33 also resets under the second spring 32 effects, recover to be meshed with lower rotating seat 31 internal gears, thereby limit adjacent two and do not need to use aid, use easily and folding convenient every blocking 1 rotation relatively, having advantages of.
