Furthermore, the locking device is a locking sleeve, and the interior of the locking sleeve is of a taper internal thread structure.

Furthermore, the end part of the connecting part of the loop bar and the telescopic bar is provided with a taper external thread.

Furthermore, four slots are arranged at the taper external thread.

Furthermore, the number of the supporting notches is four, and two adjacent supporting notches form an arc angle of 90 degrees.

The utility model discloses an useful part lies in:

the utility model provides a flexible pull rod ware is assisted in windowing, including loop bar and telescopic link, set up the pull rod ring on the loop bar, the pull rod ring can overlap on the handle of transom, thereby can realize remotely operating the transom, be equipped with the activity on the pull rod ring and detain, the activity is detained and can be convenient for the pull rod ring embolias the transom handle from the side, after the pull rod ring cover goes into the transom handle, rotate the loop bar again, the pull rod ring is retracted gradually to the loop bar in, the handle of transom is by the centre gripping between pull rod ring and loop bar, play the clamping action of certain degree. The handle that the telescopic link end set up can be convenient for personnel and grip, in addition, has set up the support breach on the telescopic link, supports the breach and can inlay on the window frame of transom, makes the window keep being in the open mode.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to fig. 1 to 3 of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Telescopic rod ware of assisting windowing, including loop bar 1 and telescopic link 2, 2 covers of telescopic link are established in loop bar 1, be equipped with one between telescopic link 2 and the loop bar 1 and be used for locking device 3 with both fixed connection, the tip of loop bar 1 is equipped with pull rod ring 4, pull rod ring 4 includes base and closed ring, be equipped with the external screw thread structure on the base, it is corresponding with it, be equipped with the internal thread structure on the loop bar 1, both connect through the helicitic texture, can adjust the high size that pull rod ring 4 exceeds 1 terminal surface of loop bar through the helicitic texture. The side of pull rod ring 4 still is equipped with the activity and detains 7, the activity is detained 7 and is had elasticity, when applying certain external force and detaining 7 in the activity, the activity is detained 7 and is inwards rotated, then a breach appears, the transom handle of being convenient for gets into pull rod ring 4 from the side, the wavy terminal surface of loop bar 1, in the in-service use, embolia the transom handle in pull rod ring 4 back, through rotatory sleeve pipe, make pull rod ring 4 screw in the sleeve pipe gradually, thereby step by step tighten the transom handle, prevent to drop. In addition, the auxiliary telescopic pull rod device for windowing has the function of supporting the ventilation window without the limiting function, and is specifically implemented by arranging a supporting notch 6 on the telescopic rod 2, fixing the support on the window width of the ventilation window, and sleeving the pull rod ring 4 on the handle of the ventilation window so as to realize the support, so that the handle of the ventilation window is tightened to avoid falling off, which is particularly important.

This supplementary flexible pull rod ware of windowing still has flexible function, establish in loop bar 1 through 2 covers with the telescopic link, then lock through locking device 3 again, thereby realize flexible function, locking device 3 can adopt the lock sleeve, the lock sleeve inner wall is equipped with the internal thread, be equipped with the external screw thread on loop bar 1 and the 2 junctions of telescopic link, the internal thread on the lock sleeve is the tapering screw thread, rotation angle is big more, locking force to both is also big more, and simultaneously, in order to make the tip of loop bar 1 have the expansion nature of reducing a little, therefore, this tip has set up four fluting 8, make the locking effect of lock sleeve better.

It is obvious to a person skilled in the art that the invention is not limited to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention, and that the embodiments are therefore to be considered in all respects as exemplary and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
