Description

M245261 V. Creative Instructions (l) < The original creative department to which the creative belongs is equipped with a handle and a lock element on the control. The elasticity and pressure of the control can be continuously completed < Previous technology > Industrial society, All non-warp panels are equipped with a technology that can be opened arbitrarily.> Provides a door screw connection closure control and pressure control components that can be unlocked for a limited time. The convenience of the electrical box is a technology that can be locked. The structure is improved, in which the base lock piece of the doorknob is provided with a pressure control at the other end of the base, and an elastic position lock control action is provided at the position of the lock control boss under the piece, and when the lock control is opened, the lock is unlocked and Unlocking the handle and simple structure of the structure are effective. The personnel who are involved in the production of processing machinery in various industries can be arbitrarily opened. Therefore, the door of the electrical box is used to ensure the safety of the electrical box, but the convenience of opening the door handle should be emphasized for convenience. Convenient and quick opening is the desired goal, but I learned that the door handle of the electrical box is set by using a lock on the lock body. After opening the lock body, it must be removed by hand. In order to make the handle on the door handle turn, it is quite inconvenient to operate, and there are quite a lot of related components in the structure, which increases its production cost and assembly difficulty, which is its disadvantage.

The creator of this creation has been engaged in the manufacturing of doorknobs and related products for many years and knows its doorknob manufacturing methods and its advantages and disadvantages. It is committed to improving its shortcomings in order to make the doorknobs more practical. After years of hard research and repeated For the trial work, he finally created the "door handle structure improvement" of this creation. < New content > The main purpose of this creation is to eliminate the above disadvantages and provide

A door connection is closed and a lock member is limited to directly reach the opening operation. The structure has a good implementation, and the structure is implemented with a structure lock piece and a control as a position lock. Close the original example and configure and special methods > improvement, where the other end of the base is locked or unlocked and the closed control is achieved, so that the pressure lock handle is placed on a door handle and a pressure action lock or open control convex key The cost-saving technology of the pieces, and the combination of its flexibility and cost are used in the detailed description of Yu Zheng. When a control button can be obtained, the moving buckle of the lock can be unscrewed and the component can be pressed. For its means and deeper and deeper, it is provided with a handlebar, a handlebar, and a control, which are operated below, and unlock the handlebar. For its effectiveness, the letter creation is specific. The elastic element action on the screw pressure control is completed to form a concave hole, and the operation action is indeed better than the above purpose. This creative department provides a designer of door handle structure improvement. In order to enable him to further understand the structural design and technology of this creation, I would like to explain it in conjunction with the drawings: I refer to Figures 1 and 2 for a three-dimensional view and a three-dimensional exploded view of this creation. The improvement mainly includes: a base (10), the front recess (11) is provided with a through hole (1 ^) ', and the rear recess (1 3) is used to accommodate an elastic element (4 0), a pressure The control (30) and the lock control (50), a convex block (1 8) is provided in the recess (13), and a convex wing (14) is provided on the outer side of the front recess (1 1); 〇), the bottom end is provided with a positioning recess (21), and the front end is provided with a screw (2 3) by a locking lever (2 2);

The Diyi convex post (5 2) is positioned as shown in the reference to Figure 4, which is based on the opening action of the door handle structure improvement: = When the key is turned, It is possible to move the latch (extended hole insertion 51) to the elastic element 50), a convex post (j 99) 99, Γ 〇) The bottom edge of the arc-shaped limiting groove (43) [432] (see FIG. 5) =) = (m-th depression (44) and stuck to the two mu positions to sense the depression of its elastic element (4 0) " ^) 4 =) and the arc-shaped limiting groove (4 3); =) (4 5 to prevent the second convex post (52) from being rotated out of the recessed recess (") in the 2 KI: base; (1〇) the bottom edge of the stop groove (43) (: 口 2; and ^ = Xi) and the arc-shaped piece (50) to control the position (0. 2) to make it lock and rotate along the mandrel (65) Pressure control (3 billion) of the convex front end 33) off: the handle (20) is positioned recesses (21)) and immediately unlocking spring (6 square) is pulled so that the trailing end Page Now tilt = 8 M245261

, It is convenient to make a twisting action, and when the handle (20) is swiveled, the locking piece (63) can be released from the buckle position, and the door panel (not shown) can be easily opened, and the handle (20) is swiveled The angle is limited by the angle limiter (6 丄) and the convex fin (1 4). ° When the other key is turned to the lock control (50), the second protruding post (52) is locked into the first recess (4 5), the first protruding post (5 1) is just turned to the arc-shaped limiting groove (4 3 The top edge (4 3 1) is against the base (丄 〇) the bumps (1 8), so the elastic element (40) has no shrinkage margin at all, and the pressure control (30) is completely incapable. When pressed, the convex buckle (3 3) can buckle the handle (20) and locate the recess (2 1), so as to achieve the effect of firmly locking the handle (20). = As can be seen from the above, through the improvement of the door handle structure, the creation of the handle is quite simple. The stable locking and unlocking of the handle can be achieved with the handle automatically springing, which facilitates the control characteristics. Unlocking and pressing the pressure control are continuous. It can be unlocked and the handle can be flipped up, with continuous operation, making it more convenient. In summary, this creation has excellent progress and practicality among similar products. At the same time, it has checked domestic and foreign technical data on such structures, and the document = the same structure exists first. With the new i patent requirements, apply according to law. The implementation of Destiny 1 is only for the purpose of illustrating this creation, so that all modifications and applications made by those skilled in the art within the scope of this creative spirit should be included in the scope of this creation. /
