Abstract
A locking device for a telescopic loop bar is positioned between adjacent loop bars, and characterized in that the locking device comprises a connecting rod, one end of the connecting rod is inserted into the loop bar to tightly fit therewith, an external screw thread with a conical surface is formed at the other end of the connecting rod, a position limiting head is arranged at the tail end of the external screw thread of the connecting rod, a locking sleeve with an internal screw thread is sheathed on the connecting rod, an opening is formed on the locking sleeve in the axial direction, and one end of the opening of the locking sleeve is inserted into an adjacent loop bar. By adopting the locking device, when the internal screw thread of the locking sleeve is screwed with the conical screw thread of the connecting rod, the axial opening of the locking sleeve gradually opens to fasten with the loop bar, especially a bulge arranged between adjacent openings of the locking sleeve is more conducive to fastening the locking sleeve and the loop bar under the same conical degree, and a radial normal pressure is generated between the locking sleeve and the screw thread of the connecting rod under the extrusion of the loop bar, so as to remarkably increase the locking frictional force and improve the locking performance, thereby improving the connection fastness and reliability.
Description
Technical field
The utility model relates to a kind of locking device of telescopic sleeving rod, in particular for the locking device of the telescopic sleeving rod of the decreased food of regulating floor mop.
Background technique
Mopstick on the market is made up of inner and outer pipe now, transfer long back by rotating and lock the length of scalable regulating handle mutually, but causing locking to connect because of moving back and forth of mop in the using process becomes flexible, the handle of elongation automatically replies shortening, need elongate handle again and regulate locking again, make troubles to use.
The model utility content
The purpose of this utility model is: the locking device that a kind of simple in structure, telescopic sleeving rod that anti-loosening property is good is provided.
The purpose of this utility model realizes by implementing following technical proposals Come:
A kind of locking device of telescopic sleeving rod, locking device is positioned between adjacent loop bar, it is characterized in that: described locking device comprises connecting rod, one end of connecting rod inserts in the loop bar drive fit with it, the other end of connecting rod has the outside thread that is the conical surface, the limited potential head of the male ends of connecting rod, tapped lock sleeve and connecting rod socket, described lock sleeve axially has opening, and an end of lock sleeve opening inserts another adjacent loop bar.
There is projection end between the adjacent apertures of described lock sleeve.
The outer peripheral surface of described lock sleeve has groove vertically.
Described lock sleeve axially has 3 openings,
Adopt the locking device of above structure, when the tapered thread rotation of lock sleeve internal thread and connecting rod is tightened, its axially open opens with loop bar fastening gradually, especially between the adjacent apertures of lock sleeve, projection is set, under identical tapering, help the fastening of lock sleeve and loop bar more, under the extruding of loop bar, produce a normal pressure radially between the screw thread of lock sleeve and connecting rod, the locking frictional force of scyewed joint is proportional with surface normal pressure, therefore, locking device of the present utility model increases greatly than the locking frictional force of the telescopic tube that regular screw threads connect, anti-loosening property obviously strengthens, thereby improves tightness and the reliability that connects.

Mark among the figure: 1 telescopic sleeving rod, 2 locking devices, 3 connecting rods, 4 lock sleeves, 5 tapered threads, 6 openings, 7 projectioies, 8 grooves, 9 spacing heads.
Embodiment
Shown in Fig. 1,2,3,4, be socketed with locking device 2 between the adjacent telescopic sleeving rod 1, locking device comprises connecting rod 3, one end of connecting rod inserts in the loop bar drive fit with it, the other end of connecting rod has the outside thread that is the conical surface, the limited potential head 9 of the male ends of connecting rod, tapped lock sleeve and connecting rod socket, lock sleeve axially has opening 6, and an end of lock sleeve opening inserts another adjacent loop bar.
As further improvement of the utility model, shown in Fig. 5,6,7, lock sleeve has 3 openings vertically, and there is projection the end between adjacent apertures, and the outer peripheral surface of lock sleeve has groove vertically.
Adopt the locking device of above structure, when the tapered thread rotation of lock sleeve internal thread and connecting rod is tightened, its axially open opens with loop bar fastening gradually, especially between the adjacent apertures of lock sleeve, projection is set, under identical tapering and reach, help the fastening of lock sleeve and loop bar more, the outer peripheral surface of lock sleeve has groove vertically, makes the pull-out capacity of lock sleeve and loop bar bigger.Under the extruding of loop bar, produce a normal pressure radially between the screw thread of lock sleeve and connecting rod, the locking frictional force of scyewed joint is proportional with surface normal pressure, therefore, locking device of the present utility model increases greatly than the locking frictional force of the telescopic tube that regular screw threads connect, anti-loosening property obviously strengthens, thereby improves tightness and the reliability that connects.
