The main purpose of the hair. Fourth, [implementation] Please refer to the sixth to eleventh diagrams. The drawer interlock provided by this studio " mainly includes a fixed seat 11, a pivot cam 12, and two sets of brake slides. 1 3 〇I The fixing base 11 is a fixing sleeve placed at one end of the guideway 3. In the fixing base n: Beton-pivot hole 1 1 1 and two opposite sides of the fixing sleeve 丨 丨 staggered two opposite sides ^ 通 α The slot hole 1 1 2 and the position 3 corresponding to this sliding slot hole 丨 丨 2 is also open and the sliding slot hole 31 corresponding to the hole diameter is also the pivot hole 丨 丨 j is recessed at a 90 ° angle on the periphery A plurality of concave arc holes 113 are provided with a stepped difference surface 114 at the bottom, and a chute hole 1 1 2 corresponding to the pivot hole 1 1 丨 a convex point 115 on each side of the central axis. The cam 1 2 is protruded from the outer edge by a stepped edge surface 丨 2 1 for the side of the / month slot 11 2 to be inserted into the above-mentioned fixed seat 丨 1 in the pivot hole 丨 丨 1 can be combined with the stepped surface 11 4 'Make the pivot cam 1 2 on one side by the 3rd block of the track, and on the other side by the stepped surface 11 4th block of the fixed seat 1 1, always keep the sleeve pivoted in the pivot hole 111 to be freely framed to avoid outward drop; An elastically movable convex dowel 122 is extended at each edge of the groove on the opposite side of the pivoting cam 丨 2, and an upper protrusion 1 23 is protruded from one side of the staggered dowel 122 staggered for the other When the upper guide groove 22 of the sliding piece 2 1 is inserted or disengaged, it can be stopped by the pivoting cam 12 to pivot at a 90-degree angle (refer to the eighth and ninth figures). At 90 degrees, the convex arc tenon 1 2 2 can be buckled into the concave arc hole 丨 3 for a certain position, so that the pivoting cam 丨 2 can perform a positioning effect after pivoting at a 90-degree angle in the pivot hole Π 1 ( (Refer to the seventh figure); In addition, the pivot cam 12 has a convex stopper 124 protruding at the bottom.

M245274 V. Creation instructions (4) Turning = ^ wheel 12 is compared with the known pivoting cam 12 ', and its side is pivoted ..., and the misalignment pivot 121, spring 124, and coupling 19R, _ Λ , 126, and other components to read the 忐, the Emperor Shatian Minyuan steel ball 125, the π π of the lower convex point 111, and the convex arc tenon 1 22 protruding around the periphery and the concave arc hole 113 of the pivot hole 111 are fixed and set You can design it-it is simpler, and you know the frame shaft 121, you must = 'make the front of the component design convex ^ t 乂 shoulders can be fixed to the track 3 with rivets,: the extension plate surface, The pivot cam 12 of this creation does not need to be riveted and positioned, but only uses the third block and pivot hole of the road! !!丨 Intercropping _, and Xi: can be achieved, assembly is quite simple.卩 Card design from ladder to surface

The externally made bone piece 13 is in the sliding slot hole 112 of the cymbal fixing base 11 and is not convexly extended. The 4 sets of the connecting brake lever 4 are linked to each other, and the opposite sides of the corresponding end M ″ i ° H32, so that the butt ends are symmetrical. The type can be inserted into the solid '= slot Γ2', so there is no need to identify the convexity of the insertion during installation. 1; 4 Α: Λ 二 ^ 皮 This relative combination can make the pivoting cam U moving slide u The groove H corresponding to the chute hole 112 leads to the groove 133 for the protrusion 115 to be inserted into the groove—a recessed guide on the upper side of the groove, and the guide groove 1 33 V protrudes into the groove surface. Can resist the bumps 丨 5 of the guide groove 133 has a limit limit for sliding outwards, H34, to guide outside, so that the drawer interlocking device 丨 the overall component can-secondary group π a hole 11 2 on the 3 channel Its formation-unit architecture can put the entire composition ^ κ d and ^ on the drawer, so the two sets of brake pads i 3 do not need to be put in another clothes, and the efficiency is simple and fast. — Individual assembly, as can be seen from the above description, this creation is shown in the specific implementation. The convex post 123 on the turning cam 12 is protruded by the front end of the track 3 L = M245274 V. Creation instructions (5) When the slot 3 2 is disengaged, it can be turned and set (refer to the ninth figure). The relative center = 12 makes a 90-degree angle pivot and also pivots a 90-degree angle to set it. The convex stop at the bottom of 1 round 12 124 Blocks 1 2 4 pushed outward and moved outwards, which caused the two sets of brake pads 1 3 to be supported by the protruding brake pads 1 3. The brake lever 4 in the corresponding position can not resist the displacement of the two groups. Upper or lower 2-shaped door: The guide groove 32 forming track 3 of the brake lever 4 is re-embedded to drive the convex lock state; Also, when the track position is set, at this time, the two sets of brake pads 13 2 = degree of thumb rotation The moving slide 1 3 can be retracted inward (the second room of the spring, so that the two sets of brake levers 4 also have a displacement: the door, to enter Λ relative to it can be moved by the opener "to make it up or down The drawer is in an unlocked state. = The improved drawer interlocking device provided by this creation makes the design of the pivoting mechanism easier, and the brake slide is changed to Lee & design, which can significantly reduce manufacturing costs and assembly man-hours, so that in addition to straight, ^ ^ 2 can more effectively enhance the competitiveness of the product, highly productive leaf use and progress. 5.
