Description
Technical field
The utility model relates to a kind of pull bar, especially relates to a kind of rotary pull bar that is mainly used in the pulling case and bag.
Background technology
The common pull bar that is used to spur case and bag generally is can only telescopic and can not rotate by vertical plane, therefore drawn case and bag heeling condition to move, can not keep level to move, when the placement thing (as pets such as doggie, kittens) in the case and bag needs to keep level, just can't realize.At present, the product that has also can rotate, but its pull bar can only have 1 section telescopic bar, and telescopic is restricted; And the rotational structure of pull bar is complicated, cost is higher, the functional reliability deficiency.
Summary of the invention
The purpose of this utility model provide a kind of not only simple in structure, reliable operation, institute take up space little, can increase and decrease the expansion link joint number arbitrarily, and rotatable rotary pull bar.
The utility model is provided with fixed bar, holder, rotating shaft and expansion link; Fixed bar one end is connected with holder, rotating shaft is located at the holder inner chamber and is rotatably assorted with the holder inner chamber, expansion link is a hollow stem, expansion link front end and rotating shaft are connected, be provided with in the centre bore of expansion link front end and jump the pearl device, jump the pearl device and be provided with bearing, push rod, spring and jumping pearl, bearing is located in the centre bore of expansion link front end, push rod is located on the bearing and with bearing and is slidingly matched, spring is located in the bearing, jump pearl one end and be connected with spring, jump the pearl other end and expose expansion link, holder is provided with for the inclined-plane of jumping the pearl wiping with for jumping the locating hole that pearl embeds.
Described fixed bar is preferably hollow stem.Described hollow stem is preferably the hollow stem of rectangular cross section.
Preferably expansion link front end and the rotating shaft interlocking that is connected of described expansion link front end and rotating shaft, be provided with radially caulking groove at rotating shaft, radially caulking groove is provided with for jumping the axially open that pearl exposes, the expansion link front end is provided with plug, the expansion link front end is embedded in radially in the caulking groove, and axially open is in the face of inclined-plane and locating hole on the holder.
Described expansion link preferably is made of at least 2 joint hollow stem sockets, and the front end of every joint hollow stem is equipped with jumps the pearl device.Described expansion link respectively save the hollow stem that hollow stem preferably is rectangular cross section.
Described holder preferably connects and composes by plate is involutory in the plate in the left side and the right side, establishes inclined-plane and locating hole in the right side on the plate.
When the utility model was used, fixed bar and holder were to be fixed on the case and bag bottom.When using, expansion link needs elongation, then the 2nd joint hollow stem is pulled out backward, the push rod of at this moment jumping the pearl device withdraws under spring action backward, spring will be jumped the pearl ejection simultaneously, and the jumping pearl that exposes contacts with the inclined-plane on the holder, and expansion link is upwards rotated, expansion link can rotate with rotating shaft, in the rotation process, jump the inclined-plane of pearl on holder and slide, after expansion link goes to certain angle, jump pearl and will embed in the locating hole, make the expansion link location.Only need set the position of locating hole as required, just can control the angle that expansion link rotates, also just can realize adjusting the residing plan-position of case and bag (as case and bag are horizontal).When not working, expansion link needs to shrink, then the 2nd joint hollow stem is promoted forward, the push rod of the jumping pearl device of the 1st joint anterior end of hollow bar can be oppressed in the bearing bottom surface of the jumping pearl device of the 2nd joint anterior end of hollow bar, make the push rod reach of the jumping pearl device of the 1st joint anterior end of hollow bar, force the spring of the jumping pearl device of the 1st joint anterior end of hollow bar to tighten up, thereby make the jumping pearl of the jumping pearl device of the 1st joint anterior end of hollow bar reclaim and do not expose, jump pearl like this and leave locating hole, expansion link just can be to turning down.When expansion link goes to original state (when expansion link and fixed bar coaxial inner conductor), expansion link can be taken in the fixed bar, can significantly reduce the utility model like this and take up space.
This shows that the utility model not only has is simple in structure, reliable operation, institute takes up space little and can increase and decrease outstanding advantage such as expansion link joint number arbitrarily, and can rotate, and uses very convenient.
