Externally locking telescopic rod of the present utility model (referring to accompanying drawing), comprise at least two joints and overlap the sleeve pipe of joining successively, and the preposition sleeve pipe (1) of adjacent casing is in the sleeve pipe (2) that inserts postposition slidably, it is characterized in that external lock being arranged in the cover portion of joining of adjacent casing, the locking swivel nut (3) that this external lock has that an end and rearmounted sleeve pipe are connected, conical external screw thread (5) and longitudinal opening (6) are joined and had to the other end and preposition casing pipe sleeve has and locks swivel nut and become the locking nut (4) of threaded engagement.
Tail end at above-mentioned Externally locking telescopic rod has the soft part (8) that touches, and cover is furnished with plug nut (11), has and match with the axial screw (12) of plug nut and there is the soft trimming bolt (14) that touches part (15) outer end in the pipe of the front end of Externally locking telescopic rod.
The pipe box that rises (10) that opening shape is arranged between the above-mentioned plug nut and the inside pipe wall of Externally locking telescopic rod front end, the said soft part (8,15) that touches is the cover hat that end face has decorative pattern (16).
Above-mentioned plug nut (11) has the inserted link hole (13) with the vertical perforation of screw (12).
Said structure of the present utility model makes it have following advantage and effect.
One, outer lock construction of the present utility model has simple in structurely, makes advantage easy to assembly.Utilize the locking nut of tapered thread structure and cooperating of the locking swivel nut that opening is arranged, can locate the design feature of the sleeve pipe that connecting is nested joins at an arbitrary position securely, it is easy to operate that this expansion link is had, and can connect needs to regulate the length of expansion link and the advantage of convenient collection.
Two, soft part, plug nut, the trimming bolt structure touched of the present utility model can be with the two ends roof pressure of expansion link on the support such as wall that match with two ends, can be convenient and install the advantage of this expansion link securely thereby have.
Three, inserted link pore structure of the present utility model, the cross bar of flag of pegging graft, thus have the advantage that can hang up flag, advertisement, sign.
The utility model can be used for family life and dries in the air clothing, extension thing as the clothing bar, hangs up coloured flag, flag long narrow flag as flagpole, hangs up advertisement, sign as advertisement bar and marker post.Provide a kind of in particular for the little person of house area and can adjust the drying rack thing bar of length arbitrarily, can play the effect that beautifies home environment according to the structure of balcony, bedroom, toilet.
Below, the utility model is further described to use embodiment and accompanying drawing thereof again.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of Externally locking telescopic rod of the present utility model.
Fig. 2 is the structural representation of the locking swivel nut of Fig. 1.
Fig. 3 is the structural representation of the locking nut of Fig. 1.
Embodiment 1
A kind of Externally locking telescopic rod of the present utility model, as shown in drawings.
Sleeve pipe 1 and sleeve pipe 2 are arranged, adopt isometrical stainless steel tube to make respectively, the external diameter of preposition sleeve pipe 1 matches with the internal diameter of rearmounted sleeve pipe 2, preposition sleeve pipe 1 can be insert slidably in the rearmounted sleeve pipe 2, is fitted with external lock in the cover portion of joining of two sleeve pipes.Locking swivel nut 3 and locking nut 4 that this external lock is made by UPVC constitute.One end of locking swivel nut 3 is solidly set on the termination portion of rearmounted sleeve pipe 2, and the other end cover of locking swivel nut fits on the outer peripheral face of preposition sleeve pipe 1, is shaped on the external screw thread 5 of taper and opens in the periphery of locking this end of swivel nut to be shaped on a plurality of uniform longitudinal openings 6.The internal thread 7 that the external screw thread 5 that is shaped in interior week with locks swivel nut of locking nut 4 matches, locking nut 4 rely on thread bush to fit on the locking swivel nut 3.Above-mentioned sleeve pipe also can have more piece, and each saves sleeve pipe and overlaps the expansion link that is made into a more piece successively one by one.
The tail end of this Externally locking telescopic rod promptly the tail end of rearmounted sleeve pipe 2 be set with the soft part 8 that touches of the cover hat made from rubber-plastics material rotationally, the soft end face that touches part is shaped on decorative pattern 9.In the front end of this Externally locking telescopic rod is the pipe of front end of preposition sleeve pipe 1, is furnished with plug nut 11 admittedly with the pipe box 10 that rises of common opening shape.The front end center of plug nut is shaped on axial screw 12, is shaped on the inserted link hole 13 of vertical perforation with screw in the screw section.Be fitted with trimming bolt 14 in screw 12, trimming bolt matches with the plug nut and is used to finely tune the length of this Externally locking telescopic rod.Be set with the soft part 15 that touches of the cover hat made from rubber-plastics material rotationally in the outer end of trimming bolt 14, the soft end face that touches part also is shaped on decorative pattern 16.
During use, the sleeve pipe 1 of this Externally locking telescopic rod is pulled out from sleeve pipe 2, place relatively to two supporting metopes between, make the length of this Externally locking telescopic rod suitable with the distance between two supporting metopes, even tail end and front end soft touches part 8 and the soft part 15 that touches is close to respectively on the two supporting metopes, rotational lock nut then, lock collar 1 and sleeve pipe 2, trimming bolt is regulated in rotation at last, fine setting increases the extended length of this Externally locking telescopic rod, what make its two ends softly touches part 8 and softly touches part 15 roof pressure and reinforcing on two supporting metopes respectively, thereby sets up this Externally locking telescopic rod securely at two supporting metopes.The two ends of expansion link can certainly be placed on respectively on the support and set up this expansion link.
Adopt the trimming bolt of present embodiment to regulate, can strengthen the strength of expansion link roof pressure metope, promptly strengthen the bearing capacity of expansion link.This expansion link is the soft part that touches of the cover hat of suit rotationally, can be close on the supporting metope, and when adjusting length of telescopic bar, rotational lock nut, rotary fine adjustment bolt, expansion link may rotate, and the soft part that touches can reduce spin friction power and avoid metope impaired.
When making coloured flag bar, long narrow flag flagpole, advertisement bar, marker post etc. with this expansion link, be vertically in the base that sleeve pipe 2 insertions of postposition are suitable and will insert this expansion link, preposition sleeve pipe 1 is pulled out desired height, and with locking nut 4 locking, then with in the inserted link hole 13 on the cross bar insertion plug nut 11 of coloured flag, long narrow flag flag, advertisement, sign, compress with trimming bolt 14 again and lock cross bar, can hang up flag, sign etc.
