[0006] In addition, as we all know, an intelligent electronic combination lock is an electronic product electronic lock that controls the operation of a circuit or a chip through a password input, so that the mechanical lock mechanism is closed and the task of unlocking and locking is completed. It has been widely used in the field of electronic locks. The use of electronic locks is usually equipped with a touch control panel. The touch control panel is exposed to the outside for a long time and is easy to be contaminated with dust. If it is not cleaned in time, the touch control panel will fail.

Embodiment Construction
[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0045] see Figure 1 to Figure 9 , the present invention provides a technical solution:
[0046] A method for unlocking a door lock, comprising the following steps:
[0047] S1. Unlock through the control panel, and then turn the handle forward;
[0048] S2-1. If the handle can rotate normally, the handle drives the external threaded rod of the safety protection mechanism to rotate, and the external threaded rod rotates while moving inward, driving the slidi...

The invention relates to the technical field of electronic locks, in particular to a method for unlocking a door lock. Unlocking is carried out through a control panel, and then the handle is turned forward; Unlock the bolt of the lock mechanism and open the door body; if the handle cannot be turned, reverse the handle afterwards, if the movable cover is not ejected to exhaust, the internal air pressure of the refrigerator is normal, and the control panel or mechanical lock mechanism is faulty; if the movable cover is Pop-up exhaust, indicating that the internal air pressure of the refrigerator is too high, and keep away from the door in time to ensure personal safety; wait for the movable cover to no longer exhaust, and then turn the handle forward to open the door; the invention is controlled by a safety protection mechanism affected by the internal air pressure of the refrigerator Unlock to ensure the safety of the operator. Check whether the control panel or the mechanical lock mechanism is faulty and whether the internal air pressure of the refrigerator is too high through the forward and reverse operation of the handle.
Description
technical field [0001] The invention relates to the technical field of electronic locks, in particular to a method for unlocking a door lock. Background technique [0002] Dry ice is solid carbon dioxide, which is obtained by condensing carbon dioxide into a colorless liquid under a pressure of 6250.5498 kPa, and then rapidly solidifying under low pressure. Block dry ice also has the function of environmental protection and energy saving. Generally, when making dry ice, the raw material is the waste discharged from the factory that contains high carbon dioxide. High-purity carbon dioxide is filtered and then made into dry ice. After use, it turns back into carbon dioxide and does not increase the amount of carbon dioxide in the atmosphere. It can be said that dry ice is a green and environmentally friendly product. Industrial molds tire molds, rubber molds, polyurethane molds, polyethylene molds, PET molds, foam molds, injection molds, alloy die-casting molds, hot core boxe...
