Abstract
The utility model discloses a rainproof cap for an exhaust port. The rainproof cap comprises a fixing component connected with an exhaust pipe and a rainproof cover and is characterized in that: an elevating bracket is arranged in the fixing component and provided with an elevating lever through hole; the upper end of the elevating lever passes through the elevating lever through hole on the elevating lever and is fixedly connected with the bottom of the rainproof cover; and the lower end of the elevating lever is positioned outside the lower port of the elevating lever through hole and is blocked by a plug. Therefore, the rainproof cover can be opened and closed automatically by an exhaust pressure, is open automatically when the exhaust port has the exhaust pressure and is closed automatically when the exhaust port does not have the exhaust pressure. When being opened completely, the rainproof cover can also play a rainproof role. When the rainproof cap for the exhaust port of the utility model is in open state or closed state, vertically falling raindrop or objects cannot enter the exhaust port, so that the defect that the conventional side-opened rainproof cap cannot block vertically falling objects under open state is overcome.
Description
Technical field:
The utility model relates to a kind of rain cover of relief opening.
Background technique:
At present, be used for the traditional laterally opened rain cover of relief opening, when opening state, relief opening top major part is in unshielded state, can not block raindrop or other object of vertical drop.
Summary of the invention:
Problem at above prior art existence, the utility model provides a kind of relief opening rain cover simple in structure, make that the lifting track of rain-proof cover of relief opening rain cover of the present utility model is a straight line, rain-proof cover can be by the automatic folding of exhaust pressure, when having exhaust pressure, opens automatically relief opening, automatically do not close when relief opening has exhaust pressure, and when rain-proof cover is opened fully, can play rainproof effect yet.
The purpose of this utility model is to realize like this, described a kind of relief opening rain cover, comprise the fixed component and the rain-proof cover that are connected with outlet pipe, its structural feature is for being provided with lifting support in fixed component, on lifting support, be provided with the lifting bar through hole, fixedly connected with the rain-proof cover bottom after passing the lifting bar through hole that lifting support is provided with in lifting bar upper end, it is outer and adopt plug to block that the lifting bar lower end is positioned at the lower end mouth of lifting bar through hole.
The purpose of this utility model also can be achieved through the following technical solutions, described a kind of relief opening rain cover, and its characteristics are that the lifting bar upper end is the center that is connected the rain-proof cover bottom; Described a kind of relief opening rain cover, its characteristics are that straight line is inserted in the parallel lifting bar through hole of lifting support relief opening center line that be provided with and outlet pipe and the lifting bar through hole is the relief opening center that is positioned at outlet pipe for the lifting bar with the rain-proof cover connection.
The beneficial effects of the utility model are: the lifting track of rain-proof cover of the present utility model is a straight line, and rain-proof cover can be opened when relief opening has exhaust pressure automatically by the automatic folding of exhaust pressure, does not close automatically when relief opening has exhaust pressure.When rain-proof cover is opened fully, also can play rainproof effect.When relief opening rain cover of the present utility model was in opening state or closed condition, the raindrop of vertical drop or junk all can not enter relief opening, had avoided traditional laterally opened rain cover can not block the shortcoming of vertical drop thing in opening state.
Description of drawings:
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is a main TV structure schematic representation of the present utility model.
Fig. 3 is the plan view of Fig. 2.
Fig. 4 is for removing the plan view behind rain-proof cover and the lifting bar among Fig. 2.
Among the figure: fixed component 1, lifting support 2, lifting bar through hole 3, rain-proof cover 4, lifting bar 5, plug 6.
Embodiment:
Below in conjunction with drawings and Examples the utility model is elaborated:
As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, a kind of relief opening rain cover described in the utility model, comprise the fixed component 1 and the rain-proof cover 4 that are connected with outlet pipe, its structural feature is for being provided with lifting support 2 in fixed component 1, lifting support 2 is provided with lifting bar through hole 3, fixedly connected with rain-proof cover 4 bottoms by passing lifting bar through hole 3 backs that lifting support 2 is provided with down in lifting bar 5 upper ends, it generally is the center that is connected rain-proof cover 4 bottoms, the lifting bar lower end is blocked by plug 6 it can not be passed from the lifting bar through hole, thereby the straight line lifting distance of restriction rain-proof cover 4 makes it to break away from outlet pipe fixed component 1.Better the lifting bar that mode is with rain-proof cover connects is that straight line is inserted in the lifting support 2 lifting bar through hole 3 parallel with the relief opening center line of outlet pipe that be provided with and lifting bar through hole 3 is positioned at the relief opening center of outlet pipe, make lifting bar 5 be positioned at the relief opening center of outlet pipe, thereby vertical line is slided in the lifting bar through hole 3 that guarantees to be provided with on lifting support 2 by lifting bar 5, make rain-proof cover 4 also along with vertical line is slided, rain-proof cover can be by the automatic folding of exhaust pressure, when having exhaust pressure, opens automatically relief opening, when having exhaust pressure, relief opening do not close automatically, thereby realize the lifting folding, and when opening fully, rain-proof cover also can hide relief opening fully, because the lifting bar 5 that is connected with rain-proof cover is in the center of relief opening, so also can play rainproof effect.That is: slide in the lifting bar through hole 3 that the lifting module that connects into of rain-proof cover and lifting bar is provided with in lifting support 2, realize oscilaltion, promptly realize the folding of relief opening rain cover.
The utility model is not stated part and is prior art.
