Abstract
The utility model relates to a lock device, in particular to a lock device for telescopic pipes, with the object to make traditional lock devices for telescopic pipes more conveniently used and more labor saving. Technically, the lock device of the utility model comprises a contractible inner sleeve, an outer sleeve capable of sliding upwardly or downwardly and a foldable handle wherein one end of the contractible inner sleeve is divided into at least two blades and the outer sleeve capable of sliding upwardly or downwardly is sleeved on the contractible inner sleeve. The two sides of the outer sleeve capable of sliding upwardly or downwardly are provided with two off-center holes, which are symmetrically arranged along with the central axis of the outer sleeve. The foldable handle is designed into a U shape, and each interior side of the two feet of the foldable handle is provided with an off-center protruding block, which flexibly corresponds to the off-center holes and is connected with the contractible inner sleeve. When the lock device of the utility model is used, force is exerted on the foldable handle first, and is then imposed on the outer sleeve capable of sliding upwardly or downwardly through eccentric wheels arranged at the interior sides of two feet of the foldable handle, which makes the outer sleeve capable of sliding upwardly or downwardly move, thereby controlling the telescopic actions of the inner pipe.
Description
Technical field
The utility model relates to a kind of locking device, especially a kind of locking device of telescopic pipe.Be applicable to that mainly mop, drying rack, glass the length of the flexible rod of daily necessities such as scrapes and regulate, capable of expansion and contraction when making flexible rod regulate length, slip phenomenon can not appear.
Background technique
In the daily life, mop need be regulated length according to individual's custom, and drying rack need be according to the size of balcony and user's height Decision Height, or the like.In the prior art, people adopt telescopic pipe to solve these problems.Model utility ZL00217925.3 discloses a kind of connecting head of Stainless Steel Tube, and it is made of fittings body and nut, and the mouth end of fittings body is provided with blade, and the blade lower end is provided with the tapered thread that cooperates with nut.Fittings body can be two logical or threeway or four-way or five-ways.During use, after the length of regulating Stainless Steel Tube, the nut of screwing on can be fixed.
This model utility finds to still have deficiency in actual use: because nut is a screw-on, so in use, application of force inconvenience, relatively require great effort, if speckle with the material of the power of reducing friction on hand, as oil, water, then knob is difficult for by turn, and is all the more so for the smaller the elderly of strength on hand.
The model utility content
The purpose of this utility model is the locking device of a kind of telescopic pipe of design, solves nut use effort in the prior art, inconvenient problem.
To achieve these goals, the utility model has adopted following technological scheme:
The utility model is a kind of locking device of telescopic pipe, comprises the interior cover of contraction, slides up and down overcoat and folding and unfolding handle, and an end of cover is divided into two blades at least in the described contraction, slides up and down overcoat and is enclosed within outside the interior cover of contraction; Respectively there is an eccentric opening the described both sides that slide up and down overcoat, and described two eccentric openings are symmetrically distributed along central shaft; Described folding and unfolding handle is the U-shaped structure, and respectively there is an eccentric projection inboard of its bipod, and described eccentric projection cooperates with eccentric opening is movable mutually, and is connected with sleeve in the contraction.
The blade of cover is four in the described contraction.
Described blade is outside from the middle part, is thickened by thin gradually.
The blade end of cover and flexible interior tube grip in the described contraction, an end of its other end and outer telescopic tube is affixed.
Described eccentric projection is an eccentric wheel.
Described eccentric opening is the eccentric wheel hole that cooperates with eccentric wheel.
Respectively there is a raised line described contraction outer wall of inside race both sides, the on-bladed end of raised line cover in shrinking.
The described outer casing inner wall that slides up and down has two sliding recess that match with raised line.
Described eccentric projection and the movable riveted joint of the interior cover of contraction.
The beneficial effects of the utility model: by the upper and lower folding and unfolding handle of stirring, make and slide up and down the upper and lower motion of outer interplanting, force the blade of cover in shrinking to tighten up or expand, make flexible in the privileged site of pipe location outer telescopic tube, make both flexible and fixedly become more laborsaving and easy.

Specific embodiment:
Below in conjunction with accompanying drawing, the utility model is elaborated: a kind of locking device of telescopic pipe, by cover 3 in shrinking, slide up and down overcoat 4 and folding and unfolding handle 5 constitutes.Be mainly used in the flexible commodity of stainless steels such as the telescoping handle of mop, cool clothing flexible rod.An end and the outer telescopic tube of cover 3 are fixed in the described contraction, and its other end is divided into four blades 31, and this blade 31, is thickened by thin to its top gradually from the middle part, and with flexible in manage 2 clampings.Respectively there is the raised line 32 of a symmetrical distribution cover 3 outer wall both sides in the described contraction, the on-bladed end of this raised line 32 cover 3 in shrinking.The described overcoat 4 that slides up and down is enclosed within outside the interior cover 3 of contraction, and respectively there is the eccentric opening 41 of a symmetrical distribution its both sides, and described overcoat 4 inwalls that slide up and down have two sliding recess 42 that match with raised line 32.Described folding and unfolding handle 5 is the U-shaped structure, and respectively there is an eccentric projection 51 inboard of its bipod, and described eccentric projection 51 cooperates with eccentric opening 41 is movable mutually, and is connected with 3 in cover in the contraction.Described eccentric projection 51 and the interior cover 3 movable riveted joints of contraction.Described eccentric projection 51 is eccentric wheel or other similar structure, and eccentric opening 41 is the eccentric wheel hole that cooperates with eccentric wheel.
Working principle of the present utility model is an example with the mop flexible rod, be described as follows: during use, upwards pull the folding and unfolding handle, the folding and unfolding handle is that rotatingshaft rotates with the rivet, the eccentric wheel of power by its bipod inboard acts directly on and slides up and down outer putting, make that sliding up and down overcoat moves down, the blade of cover tightens up in then shrinking, and interior pipe is locked.When pulling the folding and unfolding handle downwards, the eccentric wheel of power by its bipod inboard acts directly on and slides up and down outer putting, and slides up and down overcoat and moves up, and the blade of cover opens in then shrinking, and interior pipe can freely stretch.
