The secondary locking device A is provided on the knob 4 of the lock body for turning the locking tongue 3. The secondary locking device A is provided with a lock & on one side of the knob 4, and the locking post 40 in the locking block 40 is used. The knob 4 can be fixed on the inner cover 5 of the lock body, so that the door lock can be further protected by an anti-theft structure. = Please refer to the second and third figures, which are the exploded view and the three-dimensional view of this creation. It can be seen that this creation is on the side of knob 4.

40 vertical sliding sleeves are pure, the sliding sleeve seat 41 is provided with a through m block = 0 plug and connection-hole 2 ° "and a radial through plug t An accommodating groove 42 is provided with an elastic yellow 43 and a positioning post 44 abutted against the spring 43 in order by the accommodating groove 42 (please refer to Figures 4 and 5), and the locking block 40 is opposite. The two sides of the sliding socket 41's insertion hole 41 and the knob 4 are hollow rectangular bodies with open surfaces. A rectangular locking post 401 which can be inserted into the insertion hole 410 of the sliding socket 41 is provided inside. The bottom of the locking post 401 is It is a small section of cylindrical end 4101, and the inner side of the locking column 4001 is recessed with a slide groove 4012. The bottom surface of the slide groove 4012 is formed with two positioning recesses 4013, 4 0 1 4 Block 4 〇 When the locking post 4 〇 is placed in the insertion hole 410 of the sliding socket 4 丨, the positioning post of the knob 4 is placed in the groove 42 by the spring 43 against the top

44 can just abut against any of the positioning grooves 4013 and 0414 to position the locking block 400. With the above-mentioned component, the locking block 40 is used to slide on the knob 4 sliding sleeve 41 The locking post 4 01 in the locking block 40 can be made in a telescopic and protruding configuration. When the knob 4 turns the locking tongue 3 out of the locking block, the locking block 40 can be pressed to lock the locking block 40. The post 401 protrudes and is inserted into the lock body. The cover 5 is provided with a corresponding lock hole 50 in advance (as shown in the sixth figure), so that the lock core of the lock body cannot be dialed out.

Page 7 M243523 V. Creation Instructions (4) Actions' to form a secondary lock-up anti-theft reinforcement structure. For the embodiment used in this creation, please refer to the fifth and sixth figures again. When the locking block 40 is not pressed, the position of the elastic positioning post 44 is located on the positioning recess 4013 outside the bottom surface of the chute 4012, that is, the locking block 40 locks. The cylindrical end 4011 of the post 401 does not protrude from the inner edge surface of the knob 4. When the knob 4 rotates the locking tongue 3 out of the lock, 'pressing the locking block 40 can slide the elastic positioning post 44 to the bottom surface of the sliding groove 40 12 The inner side is positioned at 4014, and at the same time, the cylindrical end 4011 of the lock block 40 lock post 401 can be inserted into the lock hole 50 of the cover 5 of the lock body, so as to form a second lock anti-profit structure. If the locking device A is not released, the lock core of the door lock cannot be moved, and a highly secure lock structure is formed. As shown in Figures 7 and 8, this work is a three-dimensional exploded view and a three-dimensional view of a metal door row lock implemented in this creation. Therefore, a row lock needs to be installed in the door to add an additional anti-theft effect. The secondary locking device can be applied to the knob 4 on the replaceable lock center seat 6, that is, a lock hole 60 is provided at an appropriate outer surface of the seat of the lock center seat 6 for the creation of the secondary lock device A. If the locking block 40 of the locking column 401 is inserted, the lock core of the row of plate locks cannot be dialed to form a second-locking anti-theft structure. The disclosure of the above-mentioned embodiments is used to explain the creation, and is not intended to be used. Therefore, changes in numerical values or replacement of equivalent components are still within the scope of the creation. To sum up, the creation of "Reinforcement Structure of Door Lock Anti-Theft (I)" is indeed a very practical and progressive design. It is not only seen in any publication but also suitable for the development of the industry. In line with the new & Lee declaration requirements, apply in accordance with the law, pray for review and give to the specialist as soon as possible
