Fig. 1-Fig. 3 is a kind of trailing type accessory sucker for vacuum sweeper provided by the embodiment of the utility model, including secondary suction Disk ontology 1, one end of the accessory sucker ontology 1 and the sucker 2 of vacuum sweeper are rotatablely connected, the other end of the accessory sucker ontology 1 With notch 3, a shaft 4 is rotatably equipped in the notch 3, the shaft 4 is equipped with anticollision device, collision-prevention device, the anticollision device, collision-prevention device Include:

Sleeve 5, coaxial fixation are set in the shaft 4；

Internal baffle 6 is cylindrical structure, and is coaxially set in outside the sleeve 5, and more equidistant interval settings are passed through Telescopic rod 7 connect with the sleeve 5；

Outer baffle 8 is cylindrical structure, and is coaxially set in outside the Internal baffle 6, is set by more equidistant intervals The elastic component 9 set is connect with the Internal baffle 6, and a part of the outer baffle 8 extends to outside the notch 3.

In above-mentioned technical proposal, in order to be protected to accessory sucker, prevent its during the motion with the object in environment It collides, is provided with notch 3 in the other end of accessory sucker ontology 1, what is rotated in notch 3 is equipped with a shaft 4, and shaft 4 is equipped with Anticollision device, collision-prevention device, anticollision device, collision-prevention device include sleeve 5, Internal baffle 6 and outer baffle 8, and sleeve 5 is fixed in shaft 4, sleeve 5 and Internal baffle 6 Between connected by more telescopic rods 7, connected between outer baffle 8 and Internal baffle 6 by more elastic components 9, one of outer baffle 8 Divide and extend to outside notch 3, when accessory sucker encounters barrier, outer baffle 8 is located at a part outside notch 3 and sends out first with barrier Raw contact, 8 compression elastic piece 9 of outer baffle pass to power on Internal baffle 6, Internal baffle 6 again by compress telescopic rod 7 by power wear to On sleeve 5, sleeve 5 can mitigate part stress by rotating, and anticollision device, collision-prevention device entire in this way passes through more telescopic rods 7, more bullets The rotation of property part 9 and sleeve 5, to achieve the effect that anticollision, is protected accessory sucker to realize the buffering to external force.

In a kind of trailing type accessory sucker for vacuum sweeper, set respectively between the roof and bottom wall of the notch 3 There are top chock 10 and step 11, the top and bottom of the shaft 4 are rotatably installed in 10 He of top chock respectively In step 11.

In another technical solution, in order to realize can be rotated in notch 3 of shaft 4, in the roof and bottom wall of notch 3 Between be respectively equipped with top chock 10 and step 11, the top and bottom of shaft 4 are rotatably installed in top chock 10 respectively In step 11, such shaft 4 can rotate in notch 3 under the effect of external force.

As shown in figure 4, the telescopic rod 7 is by the first round bar in a kind of trailing type accessory sucker for vacuum sweeper 12 and inner hollow and the second round bar 13 open at one end form, one end of first round bar 12 and the inner sidewall of Internal baffle 6 Connection, the other end protrude into the opening of second round bar 13, and second round bar 13 can be axial along first round bar 12 Mobile, the sealed end of second round bar 13 is connect with the lateral wall of the sleeve 5, is equipped with a spring in second round bar 13 14, the both ends of the spring 14 connect with the other end end of the bottom wall of second round bar 13 and first round bar 12 respectively It connects.

In another technical solution, the other end of the first round bar 12 is protruded into the second round bar 13, and by spring 14 with The bottom wall elastic connection of second round bar 13, in this way when under Internal baffle 6 is by external force, Internal baffle 6 applies the first round bar 12 Add active force, 12 compressed spring 14 of the first round bar achievees the purpose that buffer external force by spring 14.

In a kind of trailing type accessory sucker for vacuum sweeper, the elastic component 9 is gas spring 14.

In another technical solution, gas spring 14 is that one kind can play support, buffering, braking, height adjustment and angle The industry accessories of the functions such as adjusting.It is made of following sections: pressure cylinder, piston rod, piston, seal guide sleeve, filler Inert gas or gas mixture, control element and the outer control element of cylinder refer to controllable gas spring 14 and connector etc. in cylinder.Principle That inert gas or gas mixture are filled in closed pressure cylinder, make the intracorporal pressure of chamber be higher than several times of atmospheric pressure or Tens times of person, it is less than the cross-sectional area of piston using the cross-sectional area of piston rod to which the pressure difference generated realizes piston rod Movement.Due to the fundamental difference in principle, gas spring 14 has a significant advantage than common spring 14: speed relatively slowly, Dynamic force change less generally within 1:1.2, be easy to control.Likewise, the first elastic component 99 can also be using high-intensitive bullet Spring 14.

In a kind of trailing type accessory sucker for vacuum sweeper, the lateral wall of the outer baffle 8 is circumferentially with along it The one outwardly projecting semi-cylindrical hill of circle.

In another technical solution, outer baffle 8 lateral wall circumferentially arranged with semicircular protrusion, it is possible to reduce it is outer Contact point when object in baffle 8 and environment contacts, to keep it more stable, the elasticity such as rubber are can be used in raised material Preferable and less big density material production.

It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality It is not limited to specific details and embodiment shown and described herein with novel.
