Abstract
The utility model relates to a telescopic rod tensioning device for telescopic rod connection. The telescopic rod tensioning device comprises a top core and an expansion sleeve, wherein the expansion sleeve is sheathed at the outer part of the top core, the top core comprises a top cap and a conical rod arranged under the top cap, the conical rod is provided with screw threads, the inner side wall of the expansion sleeve is provided with internal screw threads matched with the screw threads of the conical rod, the side wall of the expansion sleeve is longitudinally provided with a through notch. The telescopic rod tensioning device has the advantages that the fastening connection of two connected telescopic rods can be ensured only through the matching with screw thread rotation, no gap is left, the structure is simple, the operation is convenient, and the service life is long.
Description
Technical field
The utility model relates to a kind of flexible rod belt tensioner that flexible rod connects that is used for.
Background technique
At present, but existing peg has all adopted the flexible rod of rapid adjustment rod member length, and this structure is that two connecting tubes are arranged; The termination of one of them pipe inserts in another pipe, realizes stretching through tightening the nut that is arranged on the outer sleeve, and this flexible rod is when changing length; Must unscrew the nut of outer sleeve earlier; Could extract inner sleeve to needed length out, the nut of screwing again then, therefore cumbersome.In addition, because turning repeatedly of nut very easily worn and torn, in case sliding tooth, flexible rod has just lost effect fully, and therefore, working life is shorter.
The model utility content
The technical problem that the utility model will solve is: for overcoming the problem of above-mentioned existence, a kind of flexible rod belt tensioner that is used for the flexible rod connection simple in structure, easy to use is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of flexible rod belt tensioner; Comprise plunger tip and be set in the outside ringfeder pipe of plunger tip; The tapered rod that described plunger tip comprises the top cap and is arranged on cap below, top; Described tapered rod is provided with screw thread, described ringfeder pipe madial wall have with said tapered rod on the internal thread of threads engaged, described ringfeder pipe sidewall vertically offers a logical gap.
Further, offer the HALF OPENING of at least one open upper end lower end closed on the described ringfeder pipe.
Further, the quantity of described HALF OPENING is two.
Further, described plunger tip and ringfeder pipe adopt the polypropylene plastics material, have certain elasticity and toughness.
The beneficial effect of the utility model is that the flexible rod belt tensioner of the utility model only needs the matching thread rotation to guarantee that the flexible rod that two velamens connect is fastenedly connected, and does not stay the slit; Simple in structure, easy to operate, and have elasticity and toughness preferably; Be difficult for causing fracture, long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model tensioner state.

1. plunger tips among the figure, 1-1. top cap, 1-2. tapered rod, 1-3. screw thread, 2. ringfeder pipe, 2-1. gap, 2-2. HALF OPENING.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Flexible rod belt tensioner as shown in Figure 1; Comprise plunger tip 1 and be set in the outside ringfeder pipe 2 of plunger tip 1, the plunger tip 1 tapered rod 1-2 that comprises top cap 1-1 and be arranged on top cap 1-1 below wherein, tapered rod 1-2 is provided with screw thread 1-3; Install for ease; Vertically offer a logical gap 2-1 at ringfeder pipe 2 sidewalls, 2-1 is set in the plunger tip outside with ringfeder pipe 2 through this gap, in addition; Also offer the HALF OPENING 2-2 of two open upper end lower end closed on the ringfeder pipe 2, ringfeder pipe 2 madial walls have with tapered rod 1-2 on the internal thread that matches of screw thread 1-3.Thereby strutting ringfeder pipe 2, the rotation of HALF OPENING 2-2 through internal thread play position-limiting action.Secondly, for elasticity and the toughness that improves this belt tensioner, Gu plunger tip 1 and ringfeder pipe 2 are adopted the polypropylene plastics material.
Like Fig. 2, shown in Figure 3; During use plunger tip 1 is installed on the loop bar; Ringfeder pipe 2 is installed on the core bar, when being used for being connected of loop bar and core bar, only needs to cooperate internal threads and screw thread 1-3 on the plunger tip 1 to rotate ringfeder pipe 2; Can this belt tensioner be withstood core bar, thereby play the effect of fixed connection.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
