Technical Field
[0001] The utility model relates to a padlock, more specifically, it relates to a novel portable double-opening padlock. Background Art
[0002] Padlocks are the oldest and largest family of locks in the world. It can be said that other locks are derived from padlocks. The lock body of a padlock is equipped with a ring-shaped or "I"-shaped metal stem, namely the "lock beam", which allows the padlock to be directly connected to the lock body through the lock beam to form a closed lock.
[0003] The padlocks we commonly use generally adopt two opening methods: straight opening and horizontal opening. That is, when the key is inserted into the key slot of the lock core, the lock can be pulled upward without rotation. This is called a "top opening lock". This type of padlock is especially suitable for people who are holding babies or carrying items that are not suitable to put down. The so-called "double-opening padlock" refers to a lock that requires two keys to open. It has strong confidentiality and is suitable for situations where two people are required to keep and open the lock at the same time, such as warehouses, silver vaults, etc.
[0004] However, in important large-scale occasions, there are not many times when two people are required to be present at the same time, so that the double-opening padlock is completely exposed to the outside and used for a long time, so that external dust and debris can easily enter the inside of the keyhole, causing the keyhole to be blocked, thus affecting the service life of the double-opening padlock. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a novel portable double-opening padlock, which performs protective operation on the lock body to prevent the lock core from being exposed to the outside for a long time and causing dust to enter.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a novel portable double-opening padlock, comprising a lock body, a first lock hole and a second lock hole are provided on the lock body, a first lock core and a second lock core corresponding to the first lock hole and the second lock hole are arranged inside the lock body, a padlock dustproof structure is inserted into the first lock hole and the second lock hole, the padlock dustproof structure is detachably connected to the lock body, the padlock dustproof structure comprises two sealing plugs inserted into the first lock hole and the second lock hole, a fixing block fixedly connected to the two sealing plugs, a connecting block fixedly connected to the fixing block, a connecting piece arranged on the connecting block and a fixing piece arranged on the lock body, the connecting block is arranged in an L shape, and the connecting piece is detachably connected to the fixing piece.
[0007] By adopting the above technical solution, the first lock hole of the lock body corresponds to the position of the first lock core, the second lock hole corresponds to the position of the second lock core, and the two sealing plugs of the padlock dustproof structure are respectively inserted into the first lock hole and the second lock hole into the interior of the first lock core and the second lock core, thereby providing a dustproof protection for the lock body. When maintaining or repairing the lock body, the user can separate the fixing part and the connecting part, and can also clean and replace the padlock dustproof structure. When the lock body is not in use and the lock body is exposed to the external environment for a long time, the sealing plug needs to be inserted into the first lock hole and the second lock hole to protect the interior of the first lock core and the second lock core. The invention relates to a double-opening padlock, which has a simple structure and is easy to operate, and can increase the service life of the lock body. At the same time, the sense of ceremony on important occasions can be improved, and it is suitable for many occasions.
[0008] The utility model is further configured as follows: the connecting member comprises a connecting rod slidably connected to the connecting block, the fixing member comprises an insertion groove opened on the lock body and corresponding to the connecting rod, and the connecting rod is tightly fitted with the inner wall of the insertion groove.
[0009] By adopting the above technical solution, after the double-opening padlock is locked, the user inserts the sealing plug into the first lock hole and the second lock hole of the first lock core and the second lock core respectively to block the first lock hole and the second lock hole. At the same time, the connecting rod on the connecting block slides on the connecting block and protrudes outside the connecting block without being connected to the lock body. Then the user can slide the connecting rod so that the connecting rod gradually slides into the insertion groove to achieve fixation, and then the connecting block is quickly connected to the lock body, so that the padlock dustproof structure protects the lock body from dust. When the double-opening padlock needs to be opened, two users are required to be present at the same time. The two users drive the connecting rods at both ends respectively and slide the connecting rods out of the lock body, and then pull the connecting block at the same time to pull the sealing plug out of the lock hole until the entire padlock dustproof structure is separated from the lock body, and then insert the two keys into the first lock hole and the second lock hole respectively to open the double-opening padlock, thereby not only being able to provide a dustproof protection for the double-opening padlock, but also having a more ceremonial sense when opening the padlock dustproof structure and the double-opening padlock, and being applicable to various important large occasions.
[0010] The utility model is further configured as follows: a sliding groove for sliding the connecting rod is provided on the connecting rod connecting block, and a push spring is abutted between the inner wall of the sliding groove and the connecting rod.

When the user needs to continue to dust-proof the lock body, he only needs to insert the sealing plug into the lock hole to fix it, and at the same time pull the connecting rod to make the connecting rod away from the insertion groove. In this process, the connecting rod will squeeze the push spring, so that the push spring is squeezed by external force and shrinks. After the connecting rod is aligned with the insertion groove, the driving force on the connecting rod is released, and the push spring will gradually restore its length under the action of its own elastic force and push the connecting rod, and then the connecting rod will automatically be inserted into the insertion groove under the action of the spring elastic force to achieve fixation. The structure is simple and more convenient for users to operate.
[0012] The utility model is further configured as follows: a driving block is protrudingly provided on one end of the connecting rod away from the connecting block, and the driving block is used for driving the connecting rod to slide in the sliding groove.
[0013] By adopting the above technical solution, the user can drive the connecting rod to slide in the sliding groove through the driving block protruding from the connecting rod, so the user does not need to directly drive the connecting rod to slide, and the protruding driving block is more convenient for the user to operate and control.
[0014] The utility model is further configured as follows: the push springs are provided with two groups and are symmetrically arranged at both ends of the connecting rod, and both ends of the sliding groove are provided with limiting grooves for the push springs to move, so that the push springs abut between the inner wall of the limiting groove and the connecting rod.
[0015] By adopting the above technical solution, the push spring can be confined in the limit groove and will not be exposed to the outside, thereby preventing the push spring from being exposed to the outside for a long time and causing the surface to be contaminated with a lot of dust, which affects the normal elastic contraction of the push spring. The service life of the push spring and the entire dust-proof structure of the padlock can be improved, so that the dust-proof structure of the padlock can better play a dust-proof effect on the padlock.
[0016] The utility model is further configured as follows: the connecting member further comprises a first magnetic sheet arranged on the connecting rod, the fixing member further comprises a second magnetic sheet arranged in the insertion groove, and the first magnetic sheet and the second magnetic sheet are adsorbed to each other.
[0017] By adopting the above technical solution, when the connecting rod is inserted into the insertion slot, the first magnetic sheet and the second magnetic sheet will be adsorbed to each other, so that the connecting rod is more stably and with greater force when fixed in the insertion slot, thereby achieving the stability of the entire padlock dustproof structure when connected to the lock body. At the same time, the padlock dustproof structure will not easily detach from the lock body, and can achieve a better dustproof protection effect.
[0018] The utility model is further configured as follows: a wave pattern is arranged on one end of the connection block away from the lock body.
[0019] By adopting the above technical solution, the setting of the wave pattern makes the user contact with the wave pattern when pulling the connecting block to increase the friction between the connecting block and the connecting block, which is convenient for the user to pull the connecting block and the connecting block will not easily fall off the user's hand.
[0020] To sum up, the utility model has the following beneficial effects: under the action of the dustproof structure of the padlock, the lock body can be protected, so that the sealing plug is inserted into the interior of the first lock core and the second lock core to prevent the lock core from being exposed to the outside for a long time and causing dust to enter, thereby protecting the lock core and achieving a dustproof effect to increase the service life of the lock body.
