Description

Padlock with replaceable lock

The invention relates to a padlock; in particular, to a padlock with a simple structure, easy assembly, and capable of accurately positioning the opening and closing position and removing the key in the unlocked state.

Generally, the traditional padlocks are mostly formed by integrally connecting the lock core and the outer casing. As long as the lock core is damaged or the lock cannot be opened, the padlock should replace the entire lock body. Therefore, designing the padlock that can replace the lock core has become a focus of the industry. Although a number of padlocks with replaceable lock cores have appeared one after another, most of the products have problems such as complicated structure and difficult assembly.

As shown in Fig. 9, it is an exploded view of a padlock of a replaceable lock core disclosed in Chinese Patent No. CN102031905. As can be seen from the figure, such a padlock is in addition to the conventional lock body 91, the lock hook 92, the compression spring 93, the screw 94, the lock ball 95, the lock cylinder 96 and the lock core 97. The combination of a plurality of complicated components, such as the ball pin 901, the coil spring 902, the baffle 903, and the Z-shaped bridging member 904, is normally operated, and the assembly procedure is more complicated as in the paragraphs [0067] to [0074] of the patent. The described sequence of operations, wherein the step of assembly difficulty occurs more in paragraphs [0071] to [0074], that is, after the ball pin 901 is inserted into the hole 98, the coil spring 902 is inserted to cause the coil spring 902 to protrude inwardly. The portion 905 supports the pre-engaging element 906 and causes the outwardly protruding extension 907 of the coil spring 902 to be secured in the lock body 91 in a suitable manner such that the extension 907 cannot move relative to the lock body 91. After the coil spring 902 is inserted, the baffle 903 is introduced into the hole 98 according to the baffle 903, and the baffle 903 is pressed at the hole 98 so that the baffle 903 cannot move relative to the lock body 91. The baffle 903 has a rotation preventing portion 912 that protrudes radially beyond the outer circumference of the baffle 903 and reliably prevents the baffle 903 from being wound around the ball pin 901 when the baffle 903 is pressed in the lock body 91. The axis of the wheel rotates. The baffle 903 also has an opening 909 and a fan-shaped shielding area. 910 (about 120 °). After insertion of the baffle 903, the Z-shaped bridging member 904 can be inserted through the opening 909 as needed and eventually the Z-shaped bridging member 904 can be placed between the engaging elements 906, 911. Normally, the Z-shaped bridging member 904 must first be coupled to the lock cylinder 96, and then the Z-shaped bridging member 904 can be inserted into the lock body 91 together with the lock cylinder 96. Therefore, problems such as complicated assembly, inconvenience, and difficulty in forming the assembly steps are formed.

Moreover, when the padlock replaces the lock core, in addition to first removing the screw 94 to disengage the lock core 97 from the lock body 91, the lock core 97 must be poured out of the lock body 91. At this time, the lock ball 95 is included. A plurality of complicated components such as the ball pin 901, the coil spring 902, the baffle 903, and the Z-shaped bridging member 904 may simultaneously fall out of the lock body 91. The user must first reassemble the plurality of complex components to assemble a new lock core, thereby causing a new lock to be assembled. The user has trouble changing the lock.

In view of the problems of the prior art, the inventor of the present case has carefully studied and accumulated many years of experience in the product, and finally designed a padlock with a simple structure, few parts and easy assembly, and the safety is also no.虞, and not only can accurately locate the opening and closing position, but also allows the padlock user to easily remove the key design when the lock lever is opened.
