[0040] See also Figure 1-7 The present invention provides a rainproof and dustproof passive electronic lock, comprising:

[0041] Lock body 1, lock core 2 and hook 3. The lock core 2 is placed inside the lock body 1 to limit the hook 3. The position of the hook 3 is related to the state of the electronic lock.

[0042] The dustproof structure 5 is located at the end of the lock cylinder 2 where the key is inserted and extends into the interior of the lock body 1 to form a seal for the lock cylinder 2. The dustproof structure 5 includes a sealing plate 51 that can slide and change its position. An elastic member that can fit the sealing plate 51 is configured at one end of the sealing plate 51 to form a seal for the sealing plate 51.

[0043] The sealing component 4 is arranged outside the hook 3 and extends into the lock body 1 to contact the lock body 1. The sealing component 4 includes a flow groove 42 opened on the outer surface of the lock body 1. The flow groove 42 is along the outer surface of the lock body 1 toward one end of the sealing component 4.

[0044] In this embodiment, the movable positions of the lock body 1 are the lock cylinder 2 and the hook 3. During the use of the electronic lock, the electronic lock cylinder 2 is located at the bottom, and the hook 3 is located at the top. In an outdoor rainy and dusty environment, rainwater can easily enter the interior of the lock body 1 at the connection position between the hook 3 and the lock body 1, causing the electronic lock to rust, and dust has the greatest impact on the rotation of the lock cylinder 2. Therefore, a sealing component 4 is configured at the connection position between the hook 3 and the lock body 1, and a dustproof structure 5 is provided at the lock cylinder 2 position, which can prevent the electronic lock from being affected by external factors to the greatest extent.

[0045] Among them, the sealing component 4 can prevent the entry of dust after sealing the position of the hook 3 and the lock body 1, and the dust-proof structure 5 set on the outside of the lock core 2 can prevent water from seeping into the interior of the lock core 2. The sealing component 4 moves with the position of the hook 3, thereby ensuring the position stability of the sealing component 4.

[0046] In one embodiment, the sealing assembly 4 comprises:

[0047] A sealing ring 44 is sleeved on the outside of the hook 3. The outer side of the upper portion of the sealing ring 44 is arranged downwardly sloping. A sealing groove 43 is formed at a position corresponding to the lock body 1 and the sealing ring 44. The sealing ring 44 extends into the sealing groove 43 when the electronic lock is in a closed state.

[0048] The groove 41 is formed on the outer surface of the hook 3 , and the sealing ring 44 extends into the groove 41 and is limited by the groove 41 .

[0049] In this embodiment, arranging the sealing ring 44 in the groove 41 can limit the displacement of the sealing ring 44 and ensure the stability of the sealing ring 44, so that the sealing ring 44 can stably enter the sealing groove 43. The sealing ring 44 needs a certain amount of extrusion to be able to fit stably in order to perform a stable seal. After the groove 41 restricts the sealing ring 44, it can ensure that the sealing ring 44 will not be displaced due to extrusion, resulting in the problem of failing to achieve the expected sealing effect.

[0050] In one embodiment, the sealing assembly 4 further comprises:

[0051] A slot 45 is formed outside the groove 41 and communicates with the groove 41 . An end of the sealing ring 44 close to the slot 45 extends into the slot 45 to form a positioning block 46 .

[0052] The positioning ring 47 is located inside the sealing groove 43 and fixedly connected to the sealing ring 44 .

[0053] In this embodiment, the configuration of the card slot 45 and the positioning block 46 can further ensure the stability of the sealing ring 44, avoid the displacement of the sealing ring 44 during use, and do not need to deliberately adjust the position of the sealing ring 44 when the electronic lock is closed, thereby ensuring that the sealing ring 44 can seal stably.

[0054] The positioning ring 47 is configured to position the sealing ring 44 and to form a seal with the sealing groove 43 to ensure that water does not enter the sealing ring 44.

[0055] In one embodiment, the positioning ring 47 contacts the inner wall of the sealing groove 43 , and the flow groove 42 is connected to the sealing groove 43 , and the sealing ring 44 can fill the sealing groove 43 .

[0056] In this embodiment, the positioning ring 47 is used to contact the inner wall of the sealing groove 43 to form a seal on the sealing groove 43. After the sealing groove 43 is sealed, rainwater cannot penetrate into the interior of the lock body 1, and the configured flow groove 42 can prevent rainwater from accumulating in the lock body 1 and guide the rainwater to flow downward.

[0057] Among them, the sealing ring 44 covers the sealing groove 43, that is, the rainwater passing through the sealing ring 44 will flow down through the flow groove 42, and the rainwater will not remain at the position of the hook 3, thereby avoiding the penetration of rainwater. The sealing ring is set to a downhill slope, which can be an inclined surface or an arc-shaped surface, to reduce the residue of rainwater on the outer surface of the sealing ring and reduce the impact of rainwater on the sealing ring.

[0058] In one embodiment, the dustproof structure 5 includes:

[0059] A slideway 52 is provided inside the lock body 1 , and an end of the sealing plate 51 facing away from the lock core 2 extends into the slideway and contacts the slideway 52 ;

[0060] The ball 53 is disposed inside the lock body 1 and contacts an end surface of the sealing plate 51 away from the slideway 52 . The ball 53 is rollable.

[0061] In this embodiment, the configuration of the slide 52 can limit the sliding position of the sealing plate 51. A hole for inserting a key is opened in the middle of the sealing plate 51. The configuration of the hole is staggered with the lock core 2 and is sealed by the elastomer 54, thereby preventing dust from entering the lock core 2 at the hole position.

[0062] In one embodiment, the dustproof structure 5 includes:

[0063] An arc-shaped plate 56, one end of which is connected to the outer surface of the lock body 1, and an inner side of the arc-shaped plate 56 is configured to extend to an insert block 57, which is connected to the end of the arc-shaped plate 56 not connected to the lock body 1. The arc-shaped plate 56 is pressed to control the position of the insert block 57;

[0064] The positioning groove 59 is formed on one end surface of the sealing plate 51 that contacts the ball 53 . The insert block 57 can be inserted into the positioning groove 59 to limit the sealing plate 51 .

[0065] In this embodiment, the arc plate 56 is elastically arranged, that is, during use, the arc plate 56 will approach a flat plate after being pressed, and one end of the arc plate 56 is fixed, and the other end can extend away from the connection position between the arc plate 56 and the lock body 1, and drive the plug block 57 to move, so that the plug block 57 can be separated from the limit of the sealing plate 51.

[0066] Among them, there are two positioning grooves 59, and the positions of the two positioning grooves 59 correspond to the opening and sealing positions of the sealing plate 51 respectively, limiting the position of the sealing plate 51, which can ensure the sealing effect and the insertion of the key without causing wear between the key and the sealing plate 51.

[0067] The sealing plate 51 can only be displaced after the arc plate 56 is pressed, so that the key can be inserted into the lock core 2 to open the electronic lock. When the arc plate 56 is not pressed, the sealing plate 51 can be limited to ensure its stability.

[0068] In one embodiment, a spring 58 is disposed at one end of the sealing plate 51 facing away from the elastic body 54 to support the sealing plate 51 . Supported by the spring 58 , the sealing plate 51 contacts the elastic body 54 and forms a seal for the position of the lock cylinder 2 .

[0069] In this embodiment, the spring 58 forms a support for the sealing plate 51, and can form a seal by contacting with the elastic member when the sealing plate 51 loses the support of external force. After the electronic lock is closed, the arc plate 56 is pressed, and the insert 57 is disengaged from the positioning groove 59, the sealing plate 51 will form a seal with the elastomer 54 under the action of the spring 58.

[0070] In one embodiment, a diaphragm 55 is disposed outside the arc-shaped plate 56 . The diaphragm 55 is fixedly connected to the lock body 1 and forms a seal with the arc-shaped plate 56 .

[0071] In this embodiment, the configuration of the diaphragm 55 can form a seal for the position of the arc plate 56, preventing rainwater and dust from entering the interior of the lock body 1 at the position of the arc plate 56 and causing damage to the lock core 2. After the diaphragm 55 forms protection for the arc plate 56, the production cost of the arc plate 56 can be reduced, and the arc plate 56 does not have high requirements for corrosion resistance and other treatments.

[0072] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0073] 1. The present application provides a dustproof structure 5 and a sealing assembly 4 at the unlocking position of the lock cylinder 2 and the connection position between the lock body 1 and the hook 3 to ensure that when the padlock is placed in the outside for a long time, the lock cylinder 2 and the inside of the lock body 1 will not be affected by rain and dust, thereby extending the service life of the lock body 1, ensuring the stability of the lock body 1, and ensuring the normal use of the lock body 1.

[0074] 2. In the present application, the sealing plate 51 at the bottom forming the dustproof structure 5 can be controlled by the curved plate 56 on the side when in use. After the curved plate 56 is pressed, the sealing plate 51 can be displaced, so that the key can be inserted into the lock core 2 to open the electronic lock. When the curved plate 56 is not pressed, the stability of the sealing plate 51 can be limited to ensure the stability of the sealing plate 51.

[0075] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
