Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Preferred embodiment one：
This preferred embodiment provides a kind of door blocking mechanism, and it is main but does not limit to applied in refrigerator, can also use
In other devices for needing door automatic blocking.
Referring to Fig. 1, this preferred embodiment door blocking mechanism includes the mounting seat 1 and mounting seat 1 for being used to be connected with doorframe
The rotating shaft 2 of connection and the spring leaf 3 for being connected with door body 6, spring leaf 3 include side wall have opening hollow body and with
The boss 31 of the side connection of the opening of main body, rotating shaft 2 is located in the opening of hollow body side wall, the outer wall indent of rotating shaft 2
Groove 21 is formed, when door body 6 is closed, boss 31 is placed in groove 21, when door body 6 is rotated, boss 31 departs from and groove 21
Coordinate and rotated along the side wall of rotating shaft 2.Specifically, when open door body 6 when, door body 6 drive boss 31 exit groove 21 and along
Direction away from doorframe is rotated, when user unclamps door body 6, due to the elastic force of spring leaf 3, and boss 31 drives door body 6 to close
The direction of doorframe rotates up to boss 31 and is caught in groove 21, and door body 6 is closed.Spring leaf 3 can with but be not limited to by spring steel
Or the material such as stainless steel is made.Axle sleeve can with but be not limited to be made up of materials such as aluminium, copper, POM or nylon.
In the present embodiment, the boss 31 of spring leaf 3 departs from after the cooperation with the groove 21 of rotating shaft 2, and spring leaf 3 is deformed upon,
Closing force is provided for door body 6, because spring leaf 3 is more easy to deformation and intensity height, thus when being rotated relative to rotating shaft 2, abrasion is small, close
It is big with joint efforts, it is to avoid the problem of the failure easy to wear of existing door blocking mechanism.
Further, the A/F of hollow body side wall is equal to or slightly less than the external diameter equal to rotating shaft 2, so as to rotate
During, hollow body clamping rotating shaft 2 improves closing force.
The shape and structure of groove 21 and boss 31 is not specifically limited, and boss 31 can be exited in the rotation process of door body 6
Or be caught in groove 21.But preferably, the in-profile of groove 21 is adapted with the exterior contour of boss 31, boss 31
Cross section is curved, triangle or parabola shaped.When the cross section of boss 31 is curved, the central angle corresponding to arc is preferably
Less than or equal to 180 degree.
Spring leaf 3 is used to provide closing force for door body 6, and the structure of spring leaf 3 is not specifically limited, but preferably, spring
U-shaped profile, circular arc, the triangle parabola shaped or with opening of piece 3, in order to clamp rotating shaft 2.
Connected mode between rotating shaft 2 and mounting seat 1 is not specifically limited, it is ensured that rotating shaft 2 will not be with the phase of mounting seat 1
To motion.Preferably, door blocking mechanism also includes the installation axle 4 being connected with mounting seat 1, and rotating shaft 2 is sheathed on installation axle 4
