Detailed Description
The door leaf structure of the utility model will be described in more detail below in connection with the schematic drawings, in which preferred embodiments of the utility model are shown, it being understood that a person skilled in the art can modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1 and 2, an embodiment of the present utility model provides a door leaf structure, which includes a door frame 1, a fan body 2, and a sealing strip 3.
One end of the fan body 2 is hinged with one side of the door frame 1, and the other end of the fan body forms a lap joint gap with the other side of the door frame 1, so that the fan body is used for placing the sealing strip 3, and the tightness of the fan body and the sealing strip is improved.
The inside of the fan body 2 is provided with the bayonet 4 for clamping the sealing strip 3, and then compared with the mode of installing the sealing strip 3 by bonding in the prior art, the device can effectively avoid the condition that the sealing strip 3 falls off due to long-time use.
In this embodiment, a specific sealing strip 3 is provided to improve the sealing effect between the fan 2 and the door frame 1.
Specifically, the sealing strip 3 includes a clamping end 31 and a lapping end 32 matched with the bayonet 4. Namely, the sealing strip 3 is clamped in the bayonet 4 through the clamping end 31 to finish limiting, and is sealed through the lap joint end 32.
The overlap joint end 32 is arranged in the overlap joint clearance, and is provided with a deformation cavity, and the overlap joint end 32 can correspondingly deform through the arrangement of the deformation cavity and is mutually abutted with the door frame 1 under the elastic characteristic of the overlap joint end 32, so that the tightness of the door frame 1 and the fan body 2 is effectively improved.
Specifically, when the fan 2 is deflected to be in contact with the door frame 1, the overlap end 32 deforms and is in contact with the door frame 1.
This device is through forming a bayonet socket 4 between door frame 1 and fan body 2 to carry out the joint locking to sealing strip 3, thereby effectively avoid sealing strip 3 to drop because of the viscidity reduces the condition emergence, and because sealing strip 3 includes joint end 31 and overlap joint end 32, and overlap joint end 32 has the deformation chamber, and then when fan body 2 and door frame 1 are laminated, overlap joint end 32 can self-adaptation deformation and door frame 1 are hugged closely, guarantee the compactness of laminating between overlap joint end 32 and door frame 1 through the characteristic that overlap joint end 32 deformation reset promptly, with this sealed effect of promotion.
In addition, since the overlap end 32 can be deformed, a preferable sealing effect can be achieved when the weather strip 3 is partially or slightly worn.
In other embodiments, in order to reduce friction between the overlap end 32 and the door frame 1 and reduce the wear rate of the weather strip 3, the side of the overlap end 32 abutting the door frame 1 is configured in an arc shape.
Wherein the overlap end 32 is configured in a V-shaped configuration so as to form the deformation cavity for deformation reduction.
In other embodiments, the clamping end 31 is in interference fit with the bayonet 4, so as to improve tightness of the clamping connection between the sealing strip 3 and the bayonet 4.
