Detailed Description

Referring to fig. 1-6, the utility model provides a freezer sealing door, including door frame 1 and the door body 2 of mutually supporting, door frame 1 is used for setting up on the lateral wall of freezer to the outer wall of door frame 1 and the lateral wall sealing connection of freezer, door body 2 with at 1 cooperation installations of door frame, when the cooperation installation, there are two kinds of cooperation mounting means:

in a first mode

The door frame 1 is rotatably connected with one end of the door body 2, specifically, a vertical rotating shaft is arranged on one side of the door frame 1, and the door body 2 is rotatably connected with the door frame 1 through the rotating shaft, which is just a preferred example, and the door frame can be connected with the door body 2 by using a hinge (as shown in fig. 1).

Mode two

Two slide ways 14 are arranged on the outer side wall of the door frame 1 parallel to the door body 2, and the two slide ways 14 are respectively connected with the upper end and the lower end of the door body 2 in a sliding manner (as shown in fig. 4).

The two fitting installation manners are used for opening and closing the refrigeration house when goods are stored and taken, wherein a cavity 3 is arranged on one side of the door body 2 facing the door frame 1, an opening of the cavity 3 faces the door frame 1, an elastic piece is arranged on the bottom wall of the cavity 3 on the door body 2, the opening edge of the cavity 3 and one end, far away from the cavity 3, of the elastic piece are jointly hermetically connected with elastic rubber 4, a clamping groove 5 matched with the elastic rubber 4 is arranged on the inner peripheral wall of the door frame 1, an air pump 6 is arranged on the door body 2, the air pump 6 is communicated with the cavity 3 through an air pipe 7 (shown in figure 3), so that when the door body 2 needs to be closed, the door body 2 is firstly pushed to a position matched with the door frame, the air pump 6 is started, and the air pump 6 fills air into the cavity 3 to enable the elastic rubber 4 to be expanded in the clamping groove 5, thereby, the door body 2 is hermetically connected with the door frame 1, and the heat exchange of the refrigeration house through the gap between the door body 2 and the door frame 1 is prevented.

In this embodiment, the elastic member is mainly used for pulling the side of the elastic rubber 4 away from the cavity 3, so that when the air pump 6 fills air into the cavity 3, the bulging direction of the elastic rubber 4 faces the clamping groove 5, and the elastic rubber 4 is prevented from extending in a direction away from the door body 2 under the action of air pressure, so that the elastic rubber 4 is too large in thickness after being inflated and cannot be clamped into the clamping groove 5; the setting of elastic component can adopt the spring, also can adopt telescopic link 8, and when adopting

telescopic link

8, 8 perpendicular to of telescopic link door body 2 locates geometric centre department in the cavity 3 to guarantee the tensile force balance of the elastic component that elastic rubber 4 received as far as possible, prevent to explode because the local pressure that elastic rubber 4 received is too big, the top of telescopic link 8 is connected elastic rubber 4, the bottom is connected the diapire of cavity 3 for when the freezer need be opened door body 2 and is got and put the goods, can pass through the 8 shrink of telescopic link, accomodate elastic rubber 4 in cavity 3, be equipped with telescopic link control mechanism on the door body 2 for control telescopic link 8's extension and shrink, wherein, telescopic link 8 can adopt two kinds of modes:

the first method is as follows:

adopting a pneumatic telescopic rod;

when the air pressure telescopic rod is adopted (as shown in fig. 1-3), the telescopic rod control mechanism is an air pump 6, the air pump 6 is connected with the air pressure telescopic rod through an oil pipe 10 with a two-position three-way valve A9, and the expansion and contraction of the telescopic rod are controlled by matching the opening and closing of the air pump 6 with a two-position three-way valve A9.

The second method comprises the following steps:

(as shown in fig. 6) a hydraulic telescopic rod is adopted;

when adopting hydraulic telescoping rod, be equipped with oil tank 11 on the door body 2, telescopic link control mechanism is oil pump 12, oil tank 11 is connected with oil pump 12, the output of oil pump 12 is equipped with two-position three-way valve B13, the output of ooff valve B13 passes through oil pipe and connects hydraulic telescoping rod.

Under the condition to adopting telescopic link 8, as an preferred mode, the elastic component is kept away from the one end of cavity 3 still is connected with limiting plate 15, limiting plate 15 shape size with the shape size of the cross section of cavity 3 is similar, limiting plate 15 all around with the opening border of cavity 3 passes through elastic rubber 4 sealing connection further makes elastic rubber 4 fill when gaseous at air pump 6, the direction of tympanites towards draw-in groove 5 to make elastic rubber 4's outer wall closely laminate with draw-in groove 5, guarantee the gas tightness.

Under the condition of adopting telescopic link 8, as an optimal mode, the length of the opening border of cavity 3 is greater than the length of limiting plate 15 plus 4 times the thickness of elastic rubber 4, so that when elastic rubber 4 contracts, limiting plate 15 and elastic rubber 4 are not blocked in the process of being accommodated in cavity 3, and of course, the more optimal mode is that the length of the opening border of cavity 3 is slightly greater than or equal to the length of limiting plate 15 plus 4 times the thickness of elastic rubber 4 is most suitable.

As a preferable mode, the depth of the cavity 3 is greater than the length of the elastic member when the elastic member contracts plus the thickness of the limiting plate 15, so that when the elastic rubber 4 and the limiting plate 15 are accommodated in the cavity 3, the door body 2 can be more attractive, especially when the door frame 1 and the door body 2 are matched by the two slide ways 14, it is more important to completely accommodate the elastic rubber 4 and the limiting plate 15 in the cavity 3, and the door frame 1 and the door body 2 can be prevented from being clamped in the sliding matching process.
