Description

Connector for burnisher

Technical field

The present invention relates to a kind of connectors for burnisher, are typically suitable for for broom or scrub-brush to be attached to The pedestal of bristle.

Background technique

Known burnisher (usual broom or scrub-brush) includes the base part being substantially made of straight main body, in quilt It is designed on the side on ground or surface to be cleaned equipped with a large amount of bristle.

In general, the base part includes for by broomstick, (it to enable a user to operation broom on the opposite side Or scrub-brush) stablize the connector for being fixed to it.

The connector of the prior art includes the bar of protrusion, is limited for receiving the end for being exactly fitted to broomstick therein The hollow pedestal in portion.

Fixed system is set between the end of the broomstick and the bar, and the fixed system is usually by screw connection Portion's composition, pin thread on end of the screw connection portion by being formed in the broomstick and is formed in the hollow bottom Negative thread (it is engaged by screw and is engaged with the pin thread) composition of cooperation in the interior periphery wall of seat.

The broomstick, the end sections with pin thread also there is slightly frusto-conical shape so that Stronger and stable connection is realized when it is torqued-up in negative thread.

Another connection arrangement between the end of broomstick and the base part of broom or scrub-brush includes laterally prolonging A pair of holes for extending through the two, so that being coaxial when they are installed in hollow pedestal in broomstick.

Therefore, the bolt with corresponding locking nut or plug is laterally introduced to wherein, broomstick is locked In hollow pedestal.

The known connection of another kind between the end of broomstick and the base part of broom or scrub-brush includes a series of Flexible ala extends towards the broomstick from the top circumference of bar pendency, i.e., from its protrusion.

The bar has the external screw thread for be tightened in screwed ring thereon, and the screwed ring is with internal butt circle Tapered profiles are designed to install when the ring is screwed to step by step on the bar to the outer surface of the ala, To make them converge step by step along the centripetal direction of the bar.

Therefore, when the ring is tightened on the bar, the end of broomstick is held between the ala, and Broomstick is locked in the bar.

The prior art has the shortcomings that certain.

First disadvantage is, for having the broom of considerably long base part or bristle brush (such as to sweep for industry Broom or bristle brush are typical) for, bar contact by the active force that is applied in user by broomstick with passively rub Wipe machinery caused by torque generated between power (its during cleaning as bristle contact with surface to be cleaned generation) Bending stress.

Second disadvantage be, due to length usually associated with the base part of these brooms or bristle brush, connector Bar usually deviates, i.e., close to the base part, be closer to the end of user, that is, proximal end during operation Portion.

Due to the pendency of the base part (it extends along the bar, that is, extends outwardly from the connector of the broomstick) Weight, the deviation post usually generate other stress on the bar and the connector.

These stress usually cause the early fatigue of the connector, occur crack and rupture wherein and cause (i.e. Make when they only partially influence the connector) it is formed in the increased gap between the broomstick and the bar.

As such gap increases, it may cause broomstick that the bar is spontaneously slid or even caused from the bar Fracture, this finally will not be available broom or bristle brush due to using the impossibility of broomstick.

Another source of unfavorable stress includes that (it usually uses the base portion in user to the barrier of surrounding Timesharing acts on the base part) collision.

Equally, such stress is passed to the connector of broomstick, thus a possibility that further increasing damage or rupture.

Another disadvantage is, due to intensive use, above mentioned gap and the base element are to be cleaned Surface around barrier collision, broomstick may be rotated relative to the base element, so that user be prevented to restore The lock state and robustness of connector.
