Abstract

The utility model discloses an extension pipe of a duster, comprising an outer pipe and an inner pipe, wherein, the end of the outer pipe is connected with a connecting sleeve; the upper part of the connecting sleeve is provided with an opening; the opening is provided with a button which is fixedly arranged on the connecting sleeve by a retaining sleeve; a rolling needle arranged in the connecting sleeve is pressed under the button; the rolling needle falls into the concave cavity arranged on the inner pipe; a spring is arranged between the front part of the button and the connecting sleeve; the underside of the back part of the button is provided with a gap, and the rolling needle can be placed on the gap; the inner side of the lower part of the connecting sleeve is provided with a lug, and the lug is embedded into the guide groove arranged on the inner pipe. The utility model has the advantages of freely adjusting the length of the extension pipe, and good sealing performance, and thereby, the suction of the duster can not be lowered.

Description

The novel dust collector telescoping tube

The utility model relates to a kind of parts of dust catcher.

In the prior art, the suction port of dust catcher is drawn by plastic flexible pipe usually, be connected with ground brush or brush with long pipe again, long pipe is pegged graft by plurality of sections and is formed, decide according to user's the needs or the use occasion of dust catcher, the shortcoming of this type of suction pipe is: 1. the length of long pipe can not be regulated arbitrarily, and its grafting is also cumbersome; 2. after the plurality of sections long pipe connected, its sealing property was poor, gas leakage easily, thus reduced the suction of dust catcher.

The purpose of this utility model is: a kind of novel dust collector telescoping tube is provided, and this telescoping tube is length telescopic adjustment arbitrarily not only, and sealing property is also relatively good.

The technical solution of the utility model is: a kind of novel dust collector telescoping tube, comprise outer tube and interior pipe, the end of described outer tube is fixed with adapter sleeve, the top of adapter sleeve is provided with opening, is provided with button in the opening, and button is fixed to overlap and is fixed on the adapter sleeve, described button pressed downwards has the needle roller that is fixed in the adapter sleeve, in the depression that pipe go up to be provided with in needle roller fell into, be provided with spring between the front portion of button and the adapter sleeve, be provided with the breach that to place needle roller below the rear portion of button.

The further technical scheme of the utility model is: a kind of novel dust collector telescoping tube, comprise outer tube and interior pipe, the end of described outer tube is fixed with adapter sleeve, the top of adapter sleeve is provided with opening, is provided with button in the opening, and button is fixed to overlap and is fixed on the adapter sleeve, described button pressed downwards has the needle roller that is fixed in the adapter sleeve, in the depression that pipe go up to be provided with in needle roller fell into, be provided with spring between the front portion of button and the adapter sleeve, be provided with the breach that to place needle roller below the rear portion of button; The lower inside of described adapter sleeve is provided with projection, and pipe was gone up in the gathering sill that is provided with in projection embedded.

The utility model has the advantages that:

1. the utility model is made up of outer tube and interior pipe, and interior pipe freely stretches in outer tube, thereby reaches the purpose of any adjusting telescoping tube length, and the depression in interior pipe and outer tube are embedded by the needle roller on the adapter sleeve on the pipe fixes.

2. attaching parts of the present utility model are few, so its sealing property is relatively good, can not reduce the suction of dust catcher, and the front end of interior pipe can be connected use with any brush or ground brush.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model;

Wherein: 1. outer tube; 2. interior pipe; 3. adapter sleeve; 4. opening; 5. button; 6. fixed cover; 7. needle roller; 8. depression; 9. spring; 10. breach; 11. projection; 12. gathering sill.

Embodiment: as shown in the figure, a kind of novel dust collector telescoping tube, comprise outer tube [1] and interior pipe [2], the end of described outer tube [1] is fixed with adapter sleeve [3], the top of adapter sleeve [3] is provided with opening [4], be provided with button [5] in the opening [4], button [5] cover [6] that is fixed is fixed on the adapter sleeve [3], be pressed with the needle roller [7] that is fixed in the adapter sleeve [3] under the described button [5], needle roller [7] falls into interior pipe [2] and goes up in the depression [8] that is provided with, be provided with spring [9] between the front portion of button [5] and the adapter sleeve [3], be provided with the breach [10] that to place needle roller [7] below the rear portion of button [5]; The lower inside of described adapter sleeve [3] is provided with projection [11], and pipe [2] was gone up in the gathering sill [12] that is provided with in projection [11] embedded.During use, stir button [5], make needle roller [7] from depression [8], spring in the breach [10], pipe [2] in can stretching arbitrarily this moment bleeds off button [5] again, and button [5] is under the effect of spring, again needle roller [7] is pressed in the depression [8], thereby pipe [2] and outer tube [1] in fixing once more, projection [11] is that interior pipe [2] and outer tube [1] are not in use relatively rotated with the effect of gathering sill [12], thereby needle roller [7] can be embedded in the depression [8] exactly.The utility model is made up of outer tube [1] and interior pipe [2], interior pipe [2] freely stretches in outer tube [1], thereby reach the purpose of any adjusting telescoping tube length, the depression [8] in interior pipe [2] is embedded by the needle roller [7] on the adapter sleeve [3] with outer tube [1] on the pipe [2] fixes; Attaching parts of the present utility model are few, so its sealing property is relatively good, can not reduce the suction of dust catcher, and the front end of interior pipe [2] can be connected use with any brush or ground brush.
