Abstract
The utility model relates to an anti-collision suction nozzle of an outer suction dust filter, and the nozzle is characterized by comprising a suction nozzle (1); the suction nozzle (1) is arranged on a support rod (2) of the outer suction dust filter; the suction nozzle (1) is movably connected with the support rod (2) and can rotate relative to the support rod (2); the outer side of the suction nozzle (1) is fixed with a connecting rod (3); a torsional spring (4) and a limit adjustment ring (5) are arranged between the connecting rod (3) and the support rod (2). The outer side of the anti-collision suction nozzle of the outer suction dust filter is fixed with the connecting rod, the torsional spring and the limit adjustment ring are arranged between the connecting rod and the support rod, the suction nozzle can freely escape under the action of the torsional spring when being collided with the cage body of the dust filter, so as to prevent friction and collision, and guarantee the service life of the suction nozzle.
Description
Technical field
The utility model relates to a kind of suction nozzle of outer suction dirt catcher of anticollision, belongs to cleaner technical field.
Background technology
On the dust leg of outer suction dirt catcher, be connected to suction nozzle and carry out dust suction, because outer suction dirt catcher is periodic running, suction nozzle can be shown consideration for tight collision with cage in use, and long-term use meeting is ground away, thus influence power its service life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of collision, suction nozzle of the outer suction dirt catcher of the anticollision that service life is longer of preventing is provided.
The purpose of this utility model is achieved in that
The suction nozzle of the outer suction dirt catcher of the utility model anticollision, comprise suction nozzle, described suction nozzle is arranged on the support bar of outer suction dirt catcher, suction nozzle is flexibly connected with support bar, can relatively rotate with support bar, outside and the connecting rod of described suction nozzle fix, and are provided with torsion spring and spacing adjusting ring between this connecting rod and support bar.
The suction nozzle of the outer suction dirt catcher of the utility model anticollision has the following advantages:
Outside and the connecting rod of the suction nozzle of the outer suction dirt catcher of this anticollision fix, between this connecting rod and support bar, be provided with torsion spring and spacing adjusting ring, suction nozzle is when bumping with dirt catcher cage body, can under the effect of torsion spring, freely avoid, prevent that frictional impact from occurring, guaranteed the service life of suction nozzle.
Accompanying drawing explanation
Fig. 1 is the structural representation of suction nozzle of the outer suction dirt catcher of the utility model anticollision.
In figure: suction nozzle 1, support bar 2, connecting rod 3, torsion spring 4, spacing adjusting ring 5.
The specific embodiment
Referring to Fig. 1, the utility model relates to a kind of suction nozzle of outer suction dirt catcher of anticollision, comprise suction nozzle 1, described suction nozzle 1 is arranged on the support bar 2 of outer suction dirt catcher, suction nozzle 1 is flexibly connected with support bar 2, can relatively rotate with support bar 2, the outside of described suction nozzle 1 and connecting rod 3 fix, between this connecting rod 3 and support bar 2, be provided with torsion spring 4 and spacing adjusting ring 5, suction nozzle 1 is when bumping with dirt catcher cage body, can under the effect of torsion spring 4, freely avoid, prevent that frictional impact from occurring, guaranteed the service life of suction nozzle.
