Embodiment Construction

[0065] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0066] Such as figure 1 As shown, the door locking device of the present invention includes:

[0067] At least one hinge 6 for connecting the door body and the door frame, for example: the hinge 6 is arranged on the upper left part and / or the lower left part of the door body, at least one hinge 6 can output a rotation angle signal to the outside, and the rotation angle signal reflects the rotation of the hinge Angle, and then the degree of opening and closing of the door body can be known from it,

[0068] Between the door body and the door frame body, a locking mechanism 9 is provided. The locking mechanism 9 is used for manual or automatic locking and manual unlocking. The locking mechanism 9 can output the locking state signal of the locking element to the outside. Know the locking or unlocking situation of the locking mechanism 9,

[0069] Between the ...

Abstract

The invention relates to a locking device used for a door. The locking device comprises a hinge used for connecting a door body and a door frame body. The hinge can output a rotation angle signal outwards, a lock catch mechanism is arranged between the door body and the door frame body and can output a lock catch locking state signal outwards, and at least one magnetic locking mechanism is arranged between the door body and the door frame body. Controllers / a controller is arranged on the door body and / or door frame body and respectively connected with the magnetic locking mechanism, the lock catch mechanism and the hinge through cables and control the magnetic locking mechanism to be locked in an attraction mode or unlocked through the rotation angle signal and the lock catch locking state signal. The locking device is simple in structure and ingenuous in design. The controller controls the magnetic locking mechanism to be locked in the attraction mode or unlocked, the door is closed tightly, and air tightness and reliability of the door body are improved. A sheet spiral spring is built in the hinged to serve as rotation aided force, and a position sensor can be further built in the hinge to provide the rotation angle signal of the hinge outwards. Using is convenient and labor is saved.

Description

technical field [0001] The invention relates to a lock for a door, in particular to a locking device for a door. Especially door locking devices for refrigerator doors. Background technique [0002] At present, most of the refrigerator doors are closed and sealed only by the magnetic force of the door seal. Long-term use will lead to the door not being closed tightly, affecting the safety of food and ingredients stored in the refrigerator, and causing a waste of electric energy. [0003] With the enlargement and multi-functionalization of refrigerators, the number of doors on the refrigerator is also increasing, and hinges are usually installed on the door bodies to realize the rotational connection between the door body and the door frame. However, the existing hinge has a complex structure, high cost, small spring force, no function of providing rotation assistance, and cannot provide a signal of the hinge rotation angle to the outside. Contents of the invention [000...
