The utility model content
The utility model technical issues that need to address provide a kind of protecting wire net bar fold mechanism, it mainly is to solve existing in prior technology trampoline fold mechanism when folding, need add bolt fixes, comparatively inconvenience, have only vertical and two stations of level when it is folding in addition, the technical problem of the comparatively single grade of function.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Protecting wire net bar fold mechanism of the present utility model, comprise body tube, body tube one end is connected with first joint that can be connected with the body of rod, the other end that it is characterized in that described body tube is provided with second joint that can be connected with the protecting wire net bar, the second joint end is connected with rotating disk, rotating disk is hinged in the body tube by straight pin, body tube is provided with button, button is connected with locking column, the horizontal cross-under of locking column is in body tube inside, be provided with back-moving spring between button and the body tube, locking column is provided with projection or groove, and the outer rim of rotating disk is provided with groove or the projection that is complementary with projection or groove shapes.Body tube can be made one with first joint, and second joint and rotating disk are also made one, and first joint and second joint rely on rotating disk to be bolted together.Body tube be vertically to install when installing by first joint, and second joint can rotate on body tube by rotating disk, thereby guarantees that second joint has vertically and two stations of level, so on the trampoline the protecting wire net bar vertical and two stations of level are also arranged.On the protecting wire net bar, can be furnished with protecting wire net.The straight pin of pegging graft on the rotating disk is an elastic cylindrical pin, and straight pin and this body rod are orthogonal to be set up.By pressing button, locking column has two stations, promptly groove or the projection place that is inserted on the rotating disk by projection or groove finishes lockmaking, another station is then deviate from groove or projection place on the rotating disk for the projection of locking column or groove, make rotating disk to rotate freely, after back-moving spring can make and unclamp button, button was got back to original position.
As preferably, described body tube end has two cell bodies of symmetry, and disk diameter is greater than the body tube diameter, and rotating disk places in the cell body.Rotating disk can rotate in cell body, and this spline structure is comparatively compact, and the degree of depth of cell body will guarantee the groove of rotating disk or projection or the groove that projection can touch locking column.
As preferably, described button outer surface indent is in the arc-shaped, and button flushes with the body tube outer surface, can prevent that so the outstanding body tube outer surface of button from damaging human body, and button and locking column can be made one.
As preferably, described locking column is provided with projection, and the outer rim of rotating disk is provided with the groove that is complementary with the projection shape, and the quantity of groove is more than 2 or 2.Groove is a plurality of, is plugged on different grooves by projection, can adjust the angle that the protecting wire net bar is set up.
Therefore, the utlity model has folding locking device and be located at trampoline body tube inside, need not to add part during lockmaking, and a plurality of grooves are set on rotating disk, make the protecting wire net bar have a plurality of stations to select when folding, characteristics such as simple and reasonable for structure.
