Abstract

This invention provides a lock controlled latch structure featuring with electrically controlled locking/unlocking functions, comprising: a frame encasing over a latch lock body, a locking bolt provided at a top side of the frame capable of engaging into a receiving notch above the latch and forming a insertion limit to a pulling control plate to achieve the locking function of the latch. A key is used to rotate the lock core, manipulating the inward retraction of the locking bolt of the frame to release the insertion of the pulling control plate, so as to achieve the unlocking function the latch. A pull driven rod frame is pivotally connected in the lock body, and one end of the pull driven rod frame is inserted in and connected to an notch provided in the frame, while the other end is interconnected with the retraction rod of an solenoid valve, so as to enable the pull driven rod frame driving the frame ascending/descending by leverage principle, thereby causing the lock bolt to retract inward to disengage, or to insertion limit the pull control plate for electrically controlled locking or unlocking. Accordingly, the lock not only can be controlled by rotation of a key to release or insert the pull control plate, but also controlled electrically.

Description

444 Ο 95 95. Description of the invention (1) < Technical scope of the invention > The present invention relates to a door buckle structure with lock control and electric control opening and closing functions, which is mainly based on the existing lock control function of the door buckle. Under the framework, an electromagnetic valve is used to control a lever lever set on the lock frame, and then the frame can be lifted and lowered to achieve the effect of electronically controlled opening and closing, which makes it suitable for the operation of opening and closing the door buckle. Easier implementers are available. < Background description of the invention > According to the general instrument box or electrical switch box, in order to avoid being touched or damaged arbitrarily, an appropriate door buckle lock is usually provided on the door panel of the electrical switch box. It can prevent arbitrary opening, and maintain the safe use of electrical equipment 1. The structural design of the door buckle of the conventional electrical switch box is mainly as shown in Figures 1 and 2. The integrated lock case (10) is used as the main body, and the upper part of the lock case (1 0) is from the outside. An accommodating groove (1 1) is recessed, and below the accommodating groove (1 1), a groove chamber (not shown) is provided from the inside to set up a lock body (1 2). The lock body (1 2) ) Of the locking bolt (1 2 1) must penetrate into the receiving groove (1 1), a latch rod perforation (1 3) is continuously arranged on the upper end of the receiving groove (1 1) and the inner side of the receiving groove (1 3) forms a A slot seat (14) is provided with a latch lever (20) in the latch hole (13), and an outer end of the latch lever (20) can be pivotally connected with a trigger piece (21). A top abutment frame (2 2) is clamped at the end of the trigger piece (2 1), a spring (23) is provided at the center of the inner edge of the top abutment frame (22) and the trigger piece (21), and the latch lever (2 0) A spring (1 5) is sleeved through the inner section of the lock housing (1 0), and a limiting piece (1 6) and a nut (1 7)

Five 'invention description (2) is limited to the aforementioned slot seat (1 4;) Rui is locked into a nut (2 4), and the spring (1 5) of the trigger piece (2 1) is used to recover the top Sliding inside and outside to link the wall of the end of the box, and then change the opening or closing by the trigger piece (2 1 and its end locking piece (2 5)), and then press the trigger piece (3) to the trigger piece (2 1) The top flat sticker is stored in the accommodating groove (1 1 lock bolt (1 2 1) card limit 2 1) and cannot be removed to form a lock function structure. The opening and closing body of the door buckle is released to release the trigger piece. After the limit of the card is inserted, the lever of the trigger piece is operated again, and the locking bolt attached to the containing body is pressed down to form a locking effect on the trigger piece; in this case, it will be quite ashamed. Inconvenience, to be set up < A brief description of the invention > There are bells and knives knowing that the door buckle is in the development of open and special people to carry out research and improvement, and technology, and then develop the invention, and inside the latch lever (20) The final locking piece (2 5), according to the structure of the structure group and the top abutment frame (2 2), can be controlled to hold, and the lock piece (2 0) produced by the locking piece (2 5) can be locked or When the lever (20) and the angle of the switch are linked to determine the opening of the door of the switch box (21), the spring (2 hold) can be used to make the trigger piece (21) automatically, and then turn The control piece (2 1) of the control lock body (1 2), so that the control piece ('the opening and closing operation of the switch box according to this' must be controlled by the key's rotary control lock') The groove is moved to perform the unlocking action, and after the groove is controlled, the key must be controlled by the key to lock the lock card again to achieve the closing of the door buckle, so that the opening and closing operation of the door buckle can not be improved. The shortcomings in the locking operation are based on the door buckle structure based on many years of experience in the relevant industry, that is, its main purpose is

Page 5 444 0 95 V. Description of the invention (3) The innovative design of the structure, besides the lock function, can be used to simultaneously open and lock the operator more easily. Another object of the present invention is to operate the opening and closing of the door buckle in two different opening and closing operation types, so that it can achieve the purpose of unveiling. Under the existing lock control function structure of the present invention, a lever frame is actuated. And enable the lever to be installed in the lacking slot, and the lever can be linked in another way, so that the solenoid valve can pass through the frame to lift and lower the shutter to achieve the electronically controlled opening and closing operation, or Card lock control. < Detailed description of the invention > The present invention is to provide a lock control structure, in particular, through the structure control function of the structure, it is necessary to give an electric control on / off operator. Regarding the structure group of the present invention, I would like to give an example in conjunction with the diagram. First, please refer to the schematic diagram of the structural relationship in FIG. 3, as shown in the figure, so that it can be electrically controlled to open and close in the existing lock control opening of a general door buckle. The function, 俾 is given to the door buckle with both electrical control and lock control 俾 俾 can be used to meet the actual use of the key when the power is off. In terms of structural design, it is mainly that the lock body of the door buckle is assembled with a lever in a manner of ^, and the front end of the frame set by the lock body is electrically connected with the telescopic rod of the solenoid valve to control the lever bar. Pendulum tilting, locking pin retracted or card limit triggering operation, according to this, in addition to the use of the key rotation control function, the door buckle with both electric control functions and electric opening and closing functions can be designed. In order to make the existing locking and latching performance of the door buckle easier, it can be achieved in a simpler way, and the technical means and effects are achieved. The steps are described in detail below: Structure exploded view and the conclusion of Figures 4 and 5. The invention is in the structural design Up, mainly still
