Embodiment 1
A kind of internal lock of the present utility model stretches the bar that contracts, 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 the sleeve pipe 2 of postposition, and preposition sleeve pipe is inserted in the rearmounted sleeve pipe 2 for 1 one-tenth slidably.The periphery interface portion of joining portion at the cover of two sleeve pipes has sheath 3, and the front portion of sheath and preposition sleeve pipe 1 match, and its rear portion matches with the sleeve pipe 2 of postposition.The cover portion of joining at two sleeve pipes is fitted with internal lock, and locking nut 4 and clamping screw 5 that this internal lock is made by UPVC constitute.The periphery of locking nut 4 has guide groove 6 vertically, there is guide rail 7 vertically in week in the sleeve pipe of postposition, pack into rearmounted sleeve pipe 2 and guide groove 6 of locking nut 4 is movingly with guide rail 7, locking nut 4 can only be slided in the sleeve pipe 2 of postposition vertically and can not rotates.The internal thread that is shaped on taper interior week 8 of locking nut 4, locking nut have the longitudinal opening 9 and two longitudinal openings 10 of opening built in postmedian that connect vertically.The inwall of the front portion of clamping screw 5 and preposition sleeve pipe 1 is connected, and its postmedian is shaped on the external screw thread 11 that matches with the internal thread 8 of locking nut.Necking down is made at the rear portion of clamping screw 5, and makes in its back-end and prevent its chuck that is screwed out locking nut 12.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.
Tail end at this Internally locking telescopic rod is the tail end of the sleeve pipe 2 of postposition, is set with the soft part 13 that touches of the cover hat made from rubber-plastics material rotationally, and the soft end face that touches part is shaped on decorative pattern 14.In the front end of this Internally locking telescopic rod is the pipe of front end of preposition sleeve pipe 1, overlap the intrinsic trimming bolt made from UPVC 15, the fine-tuning nut made from UPVC 16 that has that its postmedian matches with trimming bolt, trimming bolt matches with fine-tuning nut and is used to finely tune the length of this Internally locking telescopic rod.Front end at fine-tuning nut relies on inside clasp 17, is connected with the T-shaped card guard ring 18 of section, is covered with the soft part 19 that touches of the cover hat made from rubber-plastics material rotationally at the front end of card guard ring.Be shaped on decorative pattern 14 at the soft end face that touches part.Thereby softly touch part 13 and softly touch tail end and the front end that part 19 places expansion link respectively.
During use, the sleeve pipe 1 of this Internally locking telescopic rod is pulled out from sleeve pipe 2, place relatively to two supporting metopes between, make the length of this Internally locking telescopic rod suitable with the distance between two supporting metopes, even tail end and front end soft touches part 13 and the soft part 19 that touches is close to respectively on the two supporting metopes, relative then revoling tube 1 and sleeve pipe 2, promptly come rotational lock bolt 5 and locking nut 4 by sleeve pipe 1 and sleeve pipe 2, with sleeve pipe 1 and sleeve pipe 2 lockings, fine-tuning nut 16 is regulated in rotation then, fine setting increases the extended length of this Internally locking telescopic rod, the soft part difference roof pressure that touches at its two ends is supported on the metopes two, thereby between two supporting metopes, set up this Internally locking telescopic rod securely, at last sheath 3 is slided to the periphery interface portion that two casing pipe sleeves are joined portion, cover the periphery interface, to increase the attractive in appearance of this expansion link.The two ends of expansion link can certainly be placed on respectively on the support and set up this expansion link.
Adopt the fine-tuning nut of present embodiment to regulate, can strengthen the strength of expansion link roof pressure metope, promptly strengthen the bearing capacity of expansion link.The rotating soft part that touches in this expansion link two ends, rely on the decorative pattern of end face can be close to the supporting metope, adjust length of telescopic bar, revoling tube lock, when the rotary fine adjustment nut increases roof pressure power, expansion link can soft touching between the part rotate at two ends, and the soft part that touches can reduce spin friction power and avoid metope impaired.
