Waterproof and dustproof device for electronic seal lock

Abstract

The invention relates to the field of machines, in particular to locksets, and particularly provides a waterproof and dustproof device for an electronic seal lock. The waterproof and dustproof device comprises a lock shell, a driving mechanism, a locking mechanism, a lock tongue hole sealing device and a waterproof ventilation valve, wherein a lock beam inserting hole and a lock tongue hole are formed in the lock shell, and perpendicular to each other; the driving mechanism is mounted in an inner cavity in the lock shell, and comprises a gear reducer motor, a motor seat, a lead screw nut transmission pair, a guiding sleeve, a sliding sleeve and a half spacer; the locking mechanism comprises a steel wire rope lock beam and a lock tongue; a central hole in a circular silicone rubber sealing component of the lock tongue hole sealing device is closely connected with a groove in the lock tongue; the circumferential area is in fit with the inner circumferential wall of the lock tongue hole and is pressed by a gland. By adopting the technical scheme, the waterproof and dustproof device has the advantages that the electronic seal lock can be completely and reliably sealed at the lock tongue and in the lock tongue hole, so that the balance among the air pressure, the humidity and the temperature of the inner cavity in the electronic seal lock can be maintained, the running of a product can be reliable, and the service life of the product can be prolonged.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a lock, and in particular to a waterproof and dustproof device for an electronic seal lock. Background technique [0002] The safety management of goods in transit is undoubtedly an important link in the modern management of the logistics industry. In order to prevent theft and exchange of goods in transit, it is necessary to prevent the unauthorised opening of the freight container while the goods are in transit. Traditional security measures mostly use disposable plastic seals or lead seals, which are easy to be imitated, easy to be illegally replaced, difficult to distinguish between true and false, and inability to immediately find problems, such as low security. At present, a variety of electronic seal locks containing modern electronic technology have gradually been widely used in the modern logistics industry. They not only have the functions of traditional plastic seals and lead...

Problems solved by technology

[0003] However, due to the limitation of the size of the electronic seal lock and the power supply capacity, etc., for the electronic seal lock with a lock beam and a deadbolt structure and a long-term reusable electronic seal lock, generally there is no reliable seal at the bolt hole, even if the printed circuit The boards are generally coated with protective paint, but complete and lasting protection is difficult to guarantee, and the protection of moving parts is even more difficult to achieve, especially the electronic seal lock is hung on the door handle and handle bracket of the freight container for a long time, and it is subjected to shock and vibration. It is also often in harsh environments such as strong sunlight, violent wind and rain, or muddy water. Therefore, among many existing electronic seal locks, after a period of normal use, there are suddenly a variety of malfunctions during operation. Analyzing the causes of electromechanical failures, most of them are caused by the intrusion of dust, water or moisture, which makes the surface of the micro-motor and its transmission parts, especially the electronic devices and their solder joints moldy and rusty.
