    • A tamper-proof device is provided for lockingly attaching a piece of equipment such as a TV set or a microwave oven to a support base. It has a pair of rigid plates that are respectively connected to the piece of equipment and the support base. One of the plates is surrounded by a flange which defines a closed area in which wedges are located to hook both plates together. The two plates are rigidly connected to each other by a screwable bolt that can be reached with a screw driver through a coaxial opening provided in the flange. A sleeve extends in between the head of the bolt and the opening. This sleeve can be closed by key-operated lock in order to prevent access to the bolt. The lock is free to rotate within the sleeve even when its latch is locked in outward position. Such prevents a theft from breaking the latch by forcing the lock into rotation in a cantilever fashion. A resilient plate is mounted within the closed area in such a manner as to extend radially close to the sleeve in order to contact the latch when the latch projects radially outwardly of the sleeve. This plate is resilient enough to let the latch flip over it if too much rotational force is applied to the lock within the sleeve.
    • 提供防篡改装置用于将诸如电视机或微波炉的一个设备的一个或多个锁定地附接到支撑基座上。 它有一对刚性板,分别连接到设备和支撑基座上。 其中一个板被法兰限定,该凸缘限定了楔形物定位的封闭区域,以将两个板钩在一起。 两个板通过可旋转的螺栓彼此刚性连接,该螺钉可以通过设置在凸缘中的同轴开口用螺丝刀到达。 套筒在螺栓的头部和开口之间延伸。 该套筒可以通过钥匙锁锁闭,以防止进入螺栓。 即使当其闩锁被锁定在向外的位置时,锁也可以在套筒内自由旋转。 这样可以通过迫使锁以悬臂方式旋转来防止盗窃破坏闩锁。 弹性板以这样一种方式安装在闭合区域内,以便径向靠近套筒,以便当闩锁径向向外伸出套筒时,弹性板与闩锁接触。 如果太多的旋转力施加到套筒内的锁,该板具有足够的弹性以使闩锁翻转。
