Description
Technical field:
The utility model relates to the technical field of ventilation shaft, more specifically to a kind of ventilating pipe cover of structure optimization.
Background technology:
The entrance and exit place of ventilation shaft is generally provided with protective cover at present; thereby ventilation blower is carried out to protective effect; but present protective cover is generally by bolted or be directly welded on ventilation shaft; and when ventilation shaft is cleaned or when ventilation blower is overhauled, all need to dismantle protective cover; protective cover dismounting is inconvenient, thereby patent 201120357161.8 discloses a kind of ventilation duct structure of protective cover for convenience detach.But its structure Shortcomings part: in the time that the wind-force in ventilation shaft is larger, its protective cover easily comes off from ventilation shaft, thereby the protective action of losing.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of ventilating pipe cover of structure optimization is provided, and it can bear larger wind-force effect in for convenience detach, the generation of the phenomenon that minimizing protective cover comes off from ventilation shaft.
Technology solution of the present utility model is as follows:
A kind of ventilating pipe cover of structure optimization, comprise ventilation duct and protective cover, the mouth of pipe place of ventilation duct forms step, four limits of protective cover are on the step of ventilation duct, one side of the ventilation duct mouth of pipe is hinged with some moving blocks, on moving block, form slot, a side of protective cover is plugged in the slot of moving block;
On the lateral wall of another side of the ventilation duct mouth of pipe relative with moving block, be fixed with some holders, on holder, be all fixed with jointed shaft, jointed shaft upper sleeve has block, on the lower surface of block, be hinged with connecting rod, on connecting rod, form pillar, pillar is inserted with torsion spring and gag lever post, and one end of torsion spring is plugged on connecting rod, other end limit is plugged on gag lever post, one end of gag lever post is hinged on hinged seat, and hinged seat is fixed on ventilation duct.
The articulated manner of described moving block is: in the both ends of the surface of moving block, all form fulcrum, fulcrum sleeve is in the articulated stand of sheet shape, and articulated stand is fixed on ventilation duct.
Described block is provided with multiple, and block is all hinged on connecting rod, and the gag lever post of connecting rod parallels with block.
Described protective cover is made up of frame and dictyosome, and the frame of protective cover leans against on the step of ventilation duct, on the dictyosome of protective cover, is fixed with handle, and one end of described block is positioned at the upside of protective cover, and connecting rod is fixed on the other end of block.
The beneficial effects of the utility model are:
It adopts rotating block to carry out spacing to protective cover, thereby can bear larger wind-force effect, the generation of the phenomenon that minimizing protective cover comes off from ventilation shaft, it is dismantled more simultaneously, has facilitated work when ventilation shaft is cleaned with to ventilation blower maintenance.

Detailed description of the invention:
Embodiment: see shown in Fig. 1 to 5, a kind of ventilating pipe cover of structure optimization, comprise ventilation duct 1 and protective cover 2, the mouth of pipe place of ventilation duct 1 forms step 1a, four limits of protective cover 2 are on the step 1a of ventilation duct 1, one side of ventilation duct 1 mouth of pipe is hinged with some moving blocks 3, forms slot 3a on moving block 3, and a side of protective cover 2 is plugged in the slot 3a of moving block 3;
On the lateral wall of another side of ventilation duct 1 mouth of pipe relative with moving block 3, be fixed with some holders 5, on holder 5, be all fixed with jointed shaft 6, jointed shaft 6 upper sleeves have block 7, on the lower surface of block 7, be hinged with connecting rod 8, on connecting rod 8, form pillar 9, pillar 9 is inserted with torsion spring 10 and gag lever post 11, and one end of torsion spring 10 is plugged on connecting rod 8, other end limit is plugged on gag lever post 11, one end of gag lever post 11 is hinged on hinged seat 12, and hinged seat 12 is fixed on ventilation duct 1.
The articulated manner of described moving block 3 is: in the both ends of the surface of moving block 3, all form fulcrum 3b, fulcrum 3b sleeve is in the articulated stand 4 of sheet shape, and articulated stand 4 is fixed on ventilation duct 1.
Described block 7 is provided with multiple, and block 7 is all hinged on connecting rod 8, and the gag lever post 11 of connecting rod 8 parallels with block 7.
Described protective cover 2 is made up of frame and dictyosome, and the frame of protective cover 2 leans against on the step 1a of ventilation duct 1, is fixed with handle 2a on the dictyosome of protective cover 2, and one end of described block 7 is positioned at the upside of protective cover 2, and connecting rod 8 is fixed on the other end of block 7.
Operation principle: the utility model is installed moving block 3 on the side of the upper end of ventilation duct 1, facilitates protective cover 2 to rotate from ventilation duct 1 and takes off; Block 7 is set on the side of ventilation duct 1 lower end simultaneously to be limited protective cover 2 and therefrom takes out, and use external force mobile link 8 to make block 7 depart from the upside of protective cover 2, thereby take out protective cover 2, and connecting rod 8 can not be moved under the active force of torsion spring 10 at ordinary times, thereby can ensure that block 7 is positioned at the upside of protective cover 2 always.
