Description

Stainless steel padlock Technical Field The utility model relates to the technical field of padlocks, in particular to a stainless steel padlock which can avoid unlocking caused by non-subjective intention due to manual mistaken touching of a lock cylinder and has a simple structure. Background Padlocks are commonly used in the fields of luggage, lockers, luggage, door handles, and the like. A conventional, typical padlock generally consists of a lock body, a U-shaped shackle, a lock cylinder, a key, and the like. The lock body is of a rectangular structure and is internally provided with a lock core, the U-shaped lock hook is arranged at one end part of the lock body, and the other end part of the lock body is provided with a key hole. When the correct key is inserted into the keyway, the lock cylinder can be rotated to disengage the locking mechanism from the U-shaped shackle, allowing the U-shaped shackle to slide out of the lock body. The short leg of the U-shaped shackle, when fully removed from or separated from the lock body in the unlocked state, allows the padlock to be removed from or hung on the clasp or other such component of the luggage case to be locked. However, the lock core of the existing padlock is generally provided with one end exposed out of the lock body, so that a key can be directly inserted into the lock core. However, due to the arrangement of the structure, the lock core is easily touched by mistake to enable the lock core to be rotated for unlocking, so that unlocking with non-subjective intention is caused, and the use safety and the user experience are further affected. In order to prevent the lock core from being accidentally touched by accident to rotate and unlock and to strengthen the encryption function of the padlock, it is common to provide an encryption side (complex tooth) on the key surface, and to add various encryption pins or thrust pins and various auxiliary springs in the lock body. However, the encryption side is arranged to cause extremely complex production process, various required accessories and high cost, which is not beneficial to popularization and application in commerce. Therefore, it is necessary to provide a stainless steel padlock capable of avoiding unlocking caused by non-subjective intention due to human error touching the lock cylinder, so as to solve the technical problems. Disclosure of utility model The utility model aims to provide a stainless steel padlock capable of avoiding unlocking caused by non-subjective intention due to human error touching a lock cylinder. In order to achieve the above purpose, the technical scheme of the utility model is that the stainless steel padlock comprises a lock body, a lock cylinder rotatably arranged in the lock body and a lock hook movably arranged in the lock body, the stainless steel padlock also comprises a lock cylinder auxiliary, the lock cylinder auxiliary is fixed in the lock body and is in butt joint with the lock cylinder, the lock cylinder auxiliary is provided with a hollow channel, the hollow channel extends along the axial direction of the lock cylinder auxiliary and penetrates through two ends of the lock cylinder auxiliary, and the hollow channel is used for a key to slide to connect or disconnect with the lock cylinder. Preferably, the stainless steel padlock further comprises a key, wherein a convex block is arranged on the surface of the key in a protruding mode, an auxiliary groove is further formed in the lock cylinder auxiliary, the auxiliary groove extends along the radial direction of the lock cylinder auxiliary and is communicated with the hollow channel, and the auxiliary groove is used for enabling the convex block to slide, so that the key can slide along the hollow channel and the auxiliary groove to enter and exit the lock cylinder. Therefore, only when the lug can be clamped into the groove of the auxiliary part and can slide along the groove, the key can be inserted into the lock cylinder to drive the lock cylinder to rotate for unlocking, and if the key is incorrect, the lug can be blocked to prevent the key from being inserted into the lock cylinder, so that the use safety is improved. In the unlocking state, the lug is just abutted against the inner side end surface of the auxiliary lock cylinder, so that the key is prevented from moving along the axial direction of the lock cylinder, the purpose of clamping the key is realized, the key can be prevented from accidentally falling off the lock body, and even if the key is subjected to outward tension, the lug is abutted against the auxiliary lock cylinder, so that the key can be prevented from being pulled out, the key is always kept on the lock body, the use experience of a user is improved, and the lug can only be rotated to a position corresponding to the groove of the auxiliary part after the lock cylinder is locked again, and can slide along the groove of the auxiliary part to take out the key. Furthermore, the oute
