Abstract
The utility model discloses a locking device for a lower installation structure of a filter. The locking device comprises a box and the filter, wherein a sealing structure is arranged between an upper side surface of the filter and the box, and an elastic support structure arranged at the bottom of the filter enables the filter to have a trend of upward movement. According to the locking device for the lower installation structure of the filter, the elastic support structure arranged at the bottom of the filter is used for offsetting the gravity of the filter, so that the filter is always in a pressed state during usage, the looseness of the connection of the filter with the box can be avoided, unfiltered upstream gases can be prevented from directly entering a clean room, and the normal use of the filter can be guaranteed.
Description
Technical field
The utility model belongs to air cleaning facility field, relates to specifically a kind of locking device for mounting structure under filter.
Background technology
Current filter is installed and generally by coupling part, filter is fixedly connected with casing, in junction, be provided with sealing gasket and prevent gas leakage, but because filter is generally heavier, after long-time use, between filter and casing, can produce loosening, thereby make between sealing gasket and casing gappedly, make the unfiltered air in upstream directly enter toilet and pollute.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of locking device for mounting structure under filter, can effectively prevent that filter from use producing loosening, thereby guarantees the service property (quality) of filter.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of locking device for mounting structure under filter, comprise casing and filter, between filter upper side and casing, be provided with hermetically-sealed construction, in the bottom of described filter, be provided with elastic support structure and make described filter there is the trend moving upward.
As further improvement of the utility model, described elastic support structure comprises T-shaped bolt, elastic component, pressing plate bracing frame, pressing plate and nut, described pressing plate bracing frame is fixed on the medial surface of described casing, and on this pressing plate bracing frame, be vertically provided with the bolt hole wearing for described T-shaped bolt, screw rod one end of described T-shaped bolt is successively from elastic component, in the bolt hole of pressing plate bracing frame and one end of pressing plate, pass, and the screw rod end of this T-shaped bolt is by described nut check and make described elastic component have elastic force straight up, the other end of described pressing plate pushes against on the downside of described filter.
As further improvement of the utility model, described elastic component is stage clip.
As further improvement of the utility model, described pressing plate bracing frame is L-type, and it is vertically held and be fixed on described box inside face, is vertically provided with bolt hole in its horizontal ends.
As further improvement of the utility model, the elastic force straight up that described elastic component has is greater than the gravity of described filter.
The beneficial effects of the utility model are: by being provided with elastic support structure in filter bottom for offsetting the gravity of filter, thereby make filter in use always in compacted state, avoid the connection of filter and casing to occur loosening, avoid upstream not filtering gas directly enter toilet, guarantee the normal use of filter.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 cross-sectional view;
Fig. 3 is the F portion structure for amplifying schematic diagram of Fig. 2;
Fig. 4 is the G portion structure for amplifying schematic diagram of Fig. 2.
By reference to the accompanying drawings, make the following instructions:
10---casing 20---filter
30---hermetically-sealed construction
1---T-shaped bolt 2---elastic component
3---pressing plate bracing frame 4---pressing plate
5---nut.
The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
A kind of locking device for mounting structure under filter, as shown in Figure 1, shown in 2,3, comprise casing 10 and filter 20, between filter upper side and casing, be provided with hermetically-sealed construction 30, in the bottom of described filter, be provided with elastic support structure and make described filter there is the trend moving upward.Like this, elastic support structure can be used for offsetting the pressure that filter causes mounting structure under filter due to self gravitation, avoid the installation of filter to occur loosening, guarantee the sealing between filter upper side and casing, thereby avoid upstream filtered gas directly to enter toilet, guarantee the normal use of filter.
Preferably, described elastic support structure comprises T-shaped bolt 1, elastic component 2, pressing plate bracing frame 3, pressing plate 4 and nut 5, as shown in Figure 4, described pressing plate bracing frame is fixed on the medial surface of described casing, and on this pressing plate bracing frame, be vertically provided with the bolt hole wearing for described T-shaped bolt, screw rod one end of described T-shaped bolt is successively from elastic component, in the bolt hole of pressing plate bracing frame and one end of pressing plate, pass, and the screw rod end of this T-shaped bolt is by described nut check and make described elastic component have elastic force straight up, the other end of described pressing plate pushes against on the downside of described filter.This elastic support structure in use; filter 20 is installed in casing 10; the other end of pulling pressing plate 4 is pushed against on the downside of filter 20; fastening nut 5 makes elastic component 2 compressed and have the elastic force that vertical pressing plate 4 makes progress; drive T-shaped bolt 1 and pressing plate 4 to move upward simultaneously; thereby offset filter because the loosening phenomenon that the factors such as self gravitation occur has protected upstream filtered air can directly not enter toilet.
Preferably, described elastic component is stage clip.
Preferably, described pressing plate bracing frame is L-type, and it is vertically held and be fixed on described box inside face, is vertically provided with bolt hole in its horizontal ends.
Preferably, the elastic force straight up that described elastic component has is greater than the gravity of described filter, to guarantee that filter is held up, thereby makes the sealing gasket between filter and casing compacted.
