Abstract
The utility model relates to an improvement on the structure of a chimney ventilating apparatus. The utility model comprises a supporter, and has the essential structure that the stationary shaft of the supporter is connected with a stanchion through a sphere, an upper cover is respectively connected with the stanchion and a rotary pipe through threads, and a rotary vane is clamped between an upper cover of the rotary pipe. The utility model can be used for avoiding the abandon of the entire rotary body when the stanchion is worn, and the assembly and the maintenance processes are simplified.
Description
The utility model relates to the improvement of chimney draft apparatus structure.
Ventilation unit in the past comprises supporter, the fixed axis 3 of supporter ' by spheroid 4 ' with revolving sleeve 2 ' be connected, revolving sleeve 2 ' on be fixed with rotary vane 6 ', rotary vane 6 ' revolution reached the purpose of ventilation.But revolving sleeve 2 ' with spheroid 4 ' contacted projection partly is with revolving sleeve 2 ' be fixed as one, promptly non-removable, contacted projection partly is parts easy to wear, therefore after wearing and tearing, whole revolving sleeve 2 ' thereupon scrap causes unnecessary waste.
The purpose of this utility model just provide a kind of with the contacted projection of spheroid partly with revolving body for removably connecting, the ventilation unit of easily assembling, maintenance.
The purpose of this utility model comes to this and realizes: the utility model comprises supporter, its structural feature is that the fixed axis of supporter links to each other with pillar by spheroid, loam cake links to each other by the same pillar of screw thread, return bend respectively, and clamping has rotary vane between the loam cake of return bend and the pillar.
Major advantage of the present utility model:
Because the utility model is provided with demountable pillar, loam cake, therefore after the pillar wearing and tearing, just can resolution stand, loam cake, pillar or loam cake changed get final product; Just can avoid the discarded of whole revolving body, and can simplify assembling, maintenance process.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of existing ventilation unit.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises supporter 1, and the fixed axis 3 of supporter 1 links to each other with pillar 9 by spheroid 4, and loam cake 7 links to each other with pillar 9, return bend 2 by screw thread 5, screw thread 11 respectively, and clamping has rotary vane 6 between the loam cake 7 of return bend 2 and the pillar 9.
For making pillar 9 contact more fully be arranged, can make pillar 9 partly be arcwall face 10 with spheroid 4 contacts with spheroid 4.
Claims (2)
1, ventilation unit comprises supporter (1), the fixed axis (3) that it is characterized in that supporter (1) links to each other by the same pillar of spheroid (4) (9), loam cake (7) links to each other by screw thread (5), the same pillar of screw thread (11) (9), return bend (2) respectively, and clamping has rotary vane (6) between the loam cake (7) of return bend (2) and the pillar (9).
2, ventilation unit according to claim 1 is characterized in that it partly is arcwall face (10) that the same spheroid of pillar (9) (4) contacts.
