Abstract
The utility model provides a telescopic rod which comprises an inner rod and an outer rod, and is characterized in that a lock sleeve is arranged on the end part of the outer rod connected with the inner rod, one end of the lock sleeve is fixed on the outer wall of the outer tube, the other end is nested on the inner rod and is provided with a hole penetrating through the inner wall of the lock sleeve, a nylon block capable of moving up and down is placed in the hole, and a rotational cam with a handle is arranged right above the nylon block. As the telescopic rod adopts the structure, and when in use, the handle is pressed and the cam presses the nylon block, and then the nylon block can tightly press the inner rod so as to realize the locking purpose, conversely, the inner rod can be loosened to realize free telescopic state, as temperature has small influence on the nylon block and the nylon block is evenly pressed as long as the handle is pressed to the position, so the nylon blockis not affected by the force application of users; compared with prior art, the telescopic rod has the advantages that the telescopic rod is convenient in use and is not affected by environment temperature, and the locking inner rod is not affected by force application volume.
Description
Technical field
The utility model relates to a kind of expansion link, mainly is used as the handle of mop.
Background technology
Existing telescoping handle mop, its handle comprises outer bar and interior mark, be provided with expansion shape retaining mechanism outside between bar and the interior bar, when inside and outside bar rotates relatively, external standard in expansion shape retaining mechanism or the locking, or inside and outside bar is unclamped, thus reach flexible purpose, the threaded sleeve that also has some to adopt band taperings oppress compression bar on the outer tube reach in the locking mode realize stretching, adopt above-mentioned dual mode to realize stretching in addition simultaneously.Adopt the combination of above-mentioned a kind of mode or dual mode all to have following defective: the first, inconsistent because of the material of retaining mechanism and inside and outside bar, thermal coefficient of expansion is also just different, when changing appears in temperature, tension appears in regular meeting can't stretch or occur loosening phenomenon, makes troubles to use; The second, its flexible realization all realizes by rotating, and can't lock when firmly not enough, can damage retaining mechanism when firmly uneven or too quickly, thereby shortened the service life of product greatly.
The utility model content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, and provides not influenced by ambient temperature, and bar is not subjected to the expansion link that size firmly influences in the locking.
The purpose of this utility model is achieved by the following technical solution: expansion link, bar and outer bar in comprising, it is characterized in that interior bar with outside the outer boom end that joins mutually of bar be provided with lock sleeve, lock sleeve one end is fixed on the outer wall of outer tube, the other end is placed on the interior pipe, and be provided with the hole of a break-through lock sleeve inwall at this end, and place nylon block moving up and down in the hole, be provided with a band handle and a rotatable cam directly over the nylon block.
Be provided with the corresponding groove of one handle shape in the lock sleeve outer wall position corresponding, in use handle be pressed into wherein, thereby realize the attractive in appearance of appearance with handle.
The utility model is owing to adopted said structure, only need during use handle is depressed, cam is depressed nylon block, nylon block will compress interior bar, thereby realize the purpose of locking, otherwise, bar was realized freely stretching in side can be unclamped, because the nylon block temperature influence is little, simultaneously, as long as handle is depressed and put in place, the pressure that nylon block is subjected to is impartial, can not be subjected to the firmly influence of size of user, compared with prior art have the advantage that bar in easy to use, not influenced by ambient temperature, the locking is not influenced by size firmly.
