Abstract
The utility model discloses a sealing structure used for a vertical lifting fast-open door, which has the advantages of reducing the cost, the welding difficulty and the punching difficulty and enhancing the smoothness of the sealing surface; the sealing structure comprises a door baffle plate, a barrel body, and a door sealing flange and a strengthening groove strip which are fixed on the outer surface of the barrel body, wherein a closed-loop sealing groove is formed on the frontal surface of the door sealing flange and opposite to one side of the door, a sealing strip is embedded in the sealing groove, the door baffle plate is fixed on the strengthening groove strip through a fixing bolt, the wall thickness of the door sealing flange is not greater than 30 mm, the width of the door sealing flange is not greater than 33 mm, and a breather pipe communicated with the sealing groove is also arranged in the door sealing flange; and the sealing structure is widely applied to the small and medium sterilizing device.
Description
Technical field
The utility model relates to vertical lift quick opening, refers more particularly to the hermetically-sealed construction of vertical lift quick opening.
Background technology
At present, domestic medical sterilizing installation manufacturing firm has adopted inserted tooth formula power door usually for the transmission mechanism of ascending/decending quick operating valve.As shown in Figure 1, the hermetically-sealed construction of inserted tooth formula power door, comprise: be welded on the door sealing flange 2 on cylindrical shell 1 end face and be welded on strengthening groove bar 4 on the barrel outer surface, for rigidity and the intensity that increases door sealing flange 2, the wall thickness of door sealing flange 2 is usually between 25～30 millimeters, and the wider width of door sealing flange 2---it is many that its external surface exceeds strengthening groove bar 4, the front of door sealing flange 2 promptly offers the seal groove of closed loop facing to the one side of door, be embedded with weather strip 3 in the seal groove, offer the gas hole 15 that communicates with seal groove in the sealing flange 2.The shortcoming of this hermetically-sealed construction is: 1, the wider width of door sealing flange, and not only increased cost, but also made that the circuit of gas hole is longer, increased the punching difficulty---be easy in the time of punching train off; 2, because the door sealing flange is to be welded on the end face of cylindrical shell, welding is difficulty relatively, and deformation quantity is bigger, influences the planeness of sealing surface.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and reduce cost, weld difficulty and punching difficulty, and can improve the hermetically-sealed construction of the vertical lift quick opening of sealing surface planeness.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the hermetically-sealed construction of vertical lift quick opening, comprise: door shield plate, cylindrical shell and be fixed on door sealing flange and strengthening groove bar on the barrel outer surface, the front of door sealing flange promptly offers the seal groove of closed loop facing to the one side of door, be embedded with weather strip in the seal groove, described door shield plate is fixed on the strengthening groove bar by set bolt, the wall thickness of described door sealing flange is not more than 30 millimeters, width is not more than 33 millimeters, also is provided with the ventilating pipe that communicates with seal groove in the door sealing flange.
The back side of described door sealing flange is fixed on the strengthening groove bar.
The beneficial effects of the utility model are: the utility model has reduced the width of door sealing flange, has reduced the difficulty of material cost and punching; And, by being sleeved on the barrel port place, the door sealing flange is grouping welding, not only reduced assembling and welding difficulty, also reduced the bulk deformation of door sealing flange, and improved the integral smoothness of its sealing surface; In addition,, strengthened door sealing flange back side intensity, effectively prevented the distortion of door sealing flange because the back side of door sealing flange is welded on the strengthening groove bar.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 2, the hermetically-sealed construction of vertical lift quick opening described in the utility model, comprise: door shield plate 7, cylindrical shell 1 and be welded on door sealing flange 2 and strengthening groove bar 4 on cylindrical shell 1 external surface---referring to shown in Figure 3, the front of door sealing flange 2 promptly offers the seal groove of closed loop facing to the one side of door 9, be embedded with sealing joint strip 3 in the seal groove---referring to Fig. 3, shown in Figure 4, described door shield plate 7 is by set bolt 6, bullet pad and nut 8 are fixed on the strengthening groove bar 4, the wall thickness of described door sealing flange 2 is not more than 30 millimeters, usually between 25～30 millimeters, the width of door sealing flange 2 is not more than 33 millimeters, usually between 28～33 millimeters, the top of door sealing flange 2 and bottom are respectively arranged with the ventilating pipe 5 that communicates with seal groove; In the present embodiment, the back side of door sealing flange 2 is welded on the strengthening groove bar 4.
During actual installation, can be according to actual needs, the gap between adjustment doors 9 and the door shield plate 7.The course of work of the present utility model is: after door 9 is shut, outside compressed air outwards pushes up the sealing joint strip in the seal groove 3 through the seal groove of ventilating pipe 5 injection door sealing flanges 2, and it is close on the door 9, keep pressure, realize effective sealing that cabinet is inner with extraneous.
Claims (2)
1. the hermetically-sealed construction of vertical lift quick opening, comprise: door shield plate, cylindrical shell and be fixed on door sealing flange and strengthening groove bar on the barrel outer surface, the front of door sealing flange promptly offers the seal groove of closed loop facing to the one side of door, be embedded with weather strip in the seal groove, it is characterized in that: described door shield plate is fixed on the strengthening groove bar by set bolt, the wall thickness of described door sealing flange is not more than 30 millimeters, width is not more than 33 millimeters, also is provided with the ventilating pipe that communicates with seal groove in the door sealing flange.
