Detailed ways

It is not difficult to obtain a deep understanding of the above-mentioned creation purposes and advantages of the utility model from the detailed description and accompanying drawings of the following selected embodiments.

First of all, please refer to Fig. 1 to Fig. 8, which is a two-way drawer cabinet locking device of the present invention, which includes a box body 10 and a locking device 20, wherein:

The box body 10 is assembled with a first side plate 101, a second side plate 102, a top plate 103 and a bottom plate 104, so that the box body 10 is a hollow cabinet body, and the first side plate 101 center A first opening 1011 is formed at an appropriate position. The box body 10 contains a plurality of two-way drawers 11 arranged up and down in sequence. A positioning boss 13 is provided at an appropriate position in the center of the outer surface of each drawer 11, and each of the drawers 11 is respectively fixed with opposite two-way slide rails 12 on its two sides, so that the drawer 11 is movably installed in the cabinet 10, and in addition, a handle 111 is respectively provided at both ends of the drawer 11, thereby facilitating left and right two-way Pull each of the drawers 11 (because it is a prior art, so do not repeat it);

The locking device 20 includes a chute 21, a linkage frame 22, a lock 23, at least one buckle 24 and an outer cover 27, wherein:

The chute 21 is roughly in the shape of a long groove and is vertically fixed at a suitable position in the center of the first side plate 101 of the box body 10 . The bottom of the chute 21 faces the position of the first opening 1011 of the first side plate 101 A second opening 213 is formed through, and a second hook portion 212 is fixed at the top of one side of the chute 21, and the second hook portion 212 has a second hook hole 2121;

The linkage frame 22 is generally in the form of a ㄇ-shaped plate structure and correspondingly slides and engages in the chute 21. It uses a plurality of long piece-shaped stoppers 25 to limit the assembly of the linkage frame 22 to the chute. 21, that is, the two ends of each limiter 25 are screwed on the first locking wall 211 of the chute 21, so that the linkage frame 22 can only be limited to slide up and down in the chute 21; A horizontally bent stop portion 222 is extended near the top end of the back of the moving frame 22, and a horizontally bent pulling portion 224 is additionally extended at the position corresponding to the second opening 213 on the back of the moving frame 22. The pulling part 224 is connected to the linkage frame 22 and is punched with at least one recessed part 2241, which has a reinforcing effect. The pulling part 224 can be moved up and down and passed through the second opening of the chute 21. 213, in addition, a first hook portion 223 is fixed on one side top of the linkage frame 22, and the first hook portion 223 has a first hook hole 2231, wherein, between the first hook hole 2231 and the second An elastic element 26 is arranged between the two hook holes 2121, which is a coil spring. Through the elastic element 26, there is an elastic reset tension between the linkage frame 22 and the chute 21, so that the linkage frame 22 returns. initial state;

The locking piece 23 is penetrated and assembled on the top side wall of the box body 10, and it is used to control and limit the vertical sliding stroke of the linkage frame 22. The locking piece 23 includes an outer end portion 231 and a locking portion 232 , the outer end 231 is screwed on the outer wall of the box body 10, so that the user can turn the lock 23 through a key 30, and the other end of the outer end 231 is provided with a locking part 232 in the linkage group. Thereby when a lock key 30 rotates the lock member 23, the locking portion 232 rotates correspondingly to the position on the top surface of the stop portion 222 of the interlocking frame 22 (as shown in FIGS. 2 to 5 ), thereby limiting The upward sliding action of the interlocking frame 22 achieves the locking effect;

The buckle 24 is correspondingly fixed on the linkage frame 22 in sequence. The buckle 24 includes a positioning groove 241 corresponding to the positioning boss 13. The positioning groove 241 consists of two relatively parallel Formed by a first edge 2411 and a second edge 2412 perpendicular to each of the first edges 2411, each of the first edges 2411 extends longitudinally along the buckle 24, and the second edge 2412 extends along the buckle 24 The horizontal extension of the positioning groove 241 is symmetrically extended on both sides of the positioning groove 241 with a second guide sliding slope 244 and a first guiding sliding slope 242. When the drawer 11 reciprocates and shifts left and right, the positioning boss 13 It can slide along the first sliding guide surface 242 and the second sliding guide surface 244, guide the up and down movement of the linkage frame 22, and then correspondingly enter the positioning groove 241, so that the positioning post 13 can block It is positioned between the first edges 2411 on the left and right ends of the positioning groove 241, so as to achieve the accurate positioning of the two-way drawer. In addition, a snap-in end 243 is protruded on both sides of the snap-fit part 24, wherein Each of the buckle parts 24 utilizes each of the snap-in ends 243 to be assembled and fixed on the linkage frame 22 (as shown in FIG. 8 );

The outer cover 27 is correspondingly pierced with a third opening 271 that communicates with the first opening 1011 of the first side plate 101 and the second opening 213 of the chute 21, and is horizontally bent and extended around the inner edge of the third opening 271. A resisting portion 272 is provided, and the outer ring surface of the resisting portion 272 abuts against the inner ring surface of the first opening 1011 and the second opening 213 correspondingly in sequence, and the outer cover 27 is assembled on the first side board 101,

The pulling part 224 passes through the second opening 213 , the first opening 1011 and the third opening 271 in sequence, so that the user can pass through the third opening 271 of the outer cover 27 and the opening of the first side plate 101 . The first opening 1011 and the second opening 213 of the chute 21 can control and lift the pulling part 224 , and then move and lift the linkage frame 22 , achieving safe, time-saving and convenient functions.

For the actual actuation of the two-way drawer cabinet locking device of the present invention, please refer to Figures 9 to 12. Figure 9 shows that the drawer 11 is in the closed and positioned state, and the positioning protrusion 13 of the drawer 11 stops Positioned in the positioning groove 241 of the buckle 24, the drawer 11 will be fixed in the box body 10 and cannot be pulled outward; when the user wants to open the drawer 11, first, pull the puller 224 upward , and then link the linkage frame 22 to move up, and at the same time, the buckle 24 is moved upwards by the drive of the linkage frame 22, until the positioning protrusion 13 of the drawer 11 is separated from the positioning concave of the buckle 24 After the first edge 2411 of the slot 241 (as shown in Figure 11), the hooking relationship between the positioning boss 13 of the drawer 11 and the positioning groove 241 of the buckle 24 can be released, and the drawer 11 at this time is Can be pulled out smoothly.

In addition, when one of the drawers 11 has not been fully pushed into the box body 10 and the lock 23 is in an unlocked state, it only needs to force the drawer 11 to be pushed into position, that is, the positioning protrusion of the drawer 11 13 Through the structure of the first guide sliding slope 242 of the buckle 24, the buckle 24 can be pushed smoothly, and the buckle 24 and the linkage frame 22 can be moved up in conjunction with each other. If the user When the drawer 11 is closed, if the applied force is too large, the positioning boss 13 can be accurately guided into the positioning groove 241 through the structure of the second guide sliding slope 244 and the first edge 2411 of the buckle 24 to avoid jamming. The fastener 24 is not firmly embedded in the positioning post 13, so as to achieve the function of accurate positioning.
