Abstract
The utility model relates to a blowing and sucking blast pipe of a blowing and sucking blower, which is designed for improving the existing blowing and sucking blast pipe whose length is not adjusted. The blowing and sucking blast pipe comprises a front blowing and sucking blast pipe and a rear blowing and sucking blast pipe which are fixed by a movable connection mechanism. The blowing and sucking blast pipe of the utility model has the advantages that the blowing and sucking blast pipe is provided with a front section and a rear section which are movably connected; therefore, the length of the blowing and sucking blast pipe can be adjusted according to actual use situation and the height of a user. The blowing and sucking blast pipe has convenient use, and enlarges the use range.
Description
Technical field
The utility model relates to a kind of parts of pressure-vaccum blower fan, particularly a kind of pressure-vaccum airduct of adjustable length.
Background technology
Existing pressure-vaccum airduct is fixed together by blower and aspiration channel, and its length immobilizes, and just can not adjust the length of pressure-vaccum airduct so in use according to environment for use and operator's factors such as height, has brought inconvenience to use.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of pressure-vaccum airduct is provided, and makes the adjustable length of its pressure-vaccum airduct, thereby reaches the convenient purpose of using.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The pressure-vaccum airduct is made up of forward and backward two sections pressure-vaccum airducts, is connected by moving connecting mechanism between forward and backward two sections pressure-vaccum airducts.
The connected mode of above-mentioned moving connecting mechanism can have varied, as bayonet type, insertion slot type, and the position of pressure-vaccum airduct, in time location and spacing before and after its role is to can adjust at any time; When needing to adjust the position, can conveniently move again.
Compared with prior art, advantage of the present utility model is the pressure-vaccum airduct is designed to two sections of front and back, flexibly connects, so adjustable length of pressure-vaccum pipe, can adjust according to actual operating position and user's height, make things convenient for use, also enlarge the scope of application.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the partial enlarged drawing of the B among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the pressure-vaccum airduct, form by fore blow aspiration channel 1, two sections pressure-vaccum airducts of after-blow aspiration channel, fore blow aspiration channel 1 front portion is divided into blower and aspiration channel by dividing plate 2, there is one section long and narrow seam 3 at fore blow aspiration channel rear portion for blower and aspiration channel separately between blower and aspiration channel, after-blow aspiration channel 5 front portions are divided into blower and aspiration channel by dividing plate 4, the dividing plate 4 of after-blow aspiration channel can move in the long and narrow seam 3 at fore blow aspiration channel rear portion, and therefore the length of whole pressure-vaccum airduct can be adjusted thereupon.
The preceding lower end of fore blow aspiration channel also has pulley 7, and whole like this pressure-vaccum airduct can conveniently move.
Fore blow aspiration channel and after-blow aspiration channel are made up of two essentially identical parts, connect by screw 8, can reduce the quantity of mould like this, reduce production costs.
