[0044] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] like Figure 1-4As shown, the locking handle 1 of the drawer slide rail in this embodiment includes a body 11, on which three mounting holes 111 are machined. The body 11 is equipped with a height adjustment mechanism 12, a left-right adjustment mechanism 13, a locking mechanism 14, and a toggle unlocking mechanism 15. The height adjustment mechanism 12 is used to adjust the height of the drawer, the left-right adjustment mechanism 13 is used to adjust the left-right position of the drawer, the locking mechanism 14 is used to fix the locking handle 1 to the drawer slide rail, thereby fixing the drawer to the drawer slide rail, and the toggle unlocking mechanism 15 is used to unlock the drawer so that the locking handle 1 can be removed from the drawer slide rail, thereby removing the drawer from the drawer slide rail.

[0046] Reference Figure 5-8 The height adjustment mechanism 12 includes a push block 121 with a push surface 1211, a first screw 122, and a first adjusting wheel 123. A first guide groove is machined on the body 11, and the push block 121 engages with the first guide groove. The push block 121 can slide back and forth along the first guide groove, meaning the push block 121 can slide along the first guide groove. Figure 4 Slide in the direction of arrow A, one end of the first screw 122 is connected to the push block 121, see reference. Figure 2 The main body 11 has a first receiving groove 112 machined on it. A first adjusting wheel 123 is rotatably installed in the first receiving groove 112. The first adjusting wheel 123 is threadedly engaged with the first screw 122. Rotating the first adjusting wheel 123 adjusts the front and rear position of the push block 121. In a preferred design, the first adjusting wheel 123 is a first adjusting gear. A first threaded hole is machined in the middle of the first adjusting gear, and the first threaded hole is threadedly engaged with the first screw 122. The pushing surface 1211 of the push block 121 is designed as an inclined surface.

[0047] Reference Figure 5 and Figure 6 , Figure 9 and Figure 10 The left-right adjustment mechanism 13 includes a slider 131, a second screw 132, and a second adjusting wheel 133. A block 1311 is machined onto the slider 131, and a second guide groove is machined onto the body 11. The slider 131 is installed in the second guide groove, and the slider 131 can slide left and right along the second guide groove. Figure 4 Sliding in the direction of arrow B, one end of the insert 1311 extends outside the body 11. One end of the second screw 132 is connected to the slider 131. A second receiving groove 113 is machined on the body 11. The second adjusting wheel 133 is rotatably installed in the second receiving groove 113. The second adjusting wheel 133 is threadedly engaged with the second screw 132. Rotating the second adjusting wheel 133 adjusts the left and right positions of the slider 131, thereby adjusting the left and right positions of the insert 1311. Preferably, the second adjusting wheel 133 is a second adjusting gear, with a second threaded hole machined in the middle, which is threadedly engaged with the second screw 132. (Refer to...) Figure 9 and Figure 10An elastic edge 1312 is machined on one side of the upper block 1311 of the slider 131, and one end of the elastic edge 1312 extends outward at an angle to the outside of the body 11.

[0048] The body 11 is machined with a third guide groove. The locking mechanism 14 includes an elastic element (not shown in the figure) and a locking block 141 machined with a slot 1411. The locking block 141 can extend and retract on the body 11, that is, the locking block 141 can extend and retract on the body 11. Figure 4 The direction of arrow B indicates the extension / retraction motion. The elastic element is designed as a spring, as shown in the reference. Figure 5 and Figure 6 The locking block 141 has a fitting hole 1412. One end of the spring is fitted into the fitting hole 1412, and the other end is connected to the body 11. In its natural state, the spring is in a compressed state, and the spring applies an elastic force to the locking block 141, causing the locking block 141 to extend. In a preferred design, the slot 1411 has a "7"-shaped structure, and one side of the slot 1411 on the locking block 141 has an inclined engaging surface 14111, which is close to the insert block 1311.

[0049] Reference Figure 5 and Figure 6 The toggle unlocking mechanism 15 includes a lever 151, which is hinged to the body 11. One end of the lever 151 has a toggle block 1511 machined thereon. One side of the locking block 141 has a groove 1413 shaped like a "︹", and the toggle block 1511 engages with the groove 1413. A toggle part 1512 is machined on the lever 151, extending beyond the body 11. The toggle part 1512 has anti-slip textures. Figure 4 When the lever 151 is moved in the direction of arrow C, the lever 151 drives the lock block 141 to retract, thereby unlocking the device.

[0050] Reference Figure 11 The drawer slides include a fixed rail 2, a middle rail 3, and a movable rail 4. The fixed rail 2 and the middle rail 3 are movably connected, allowing the middle rail 3 to slide on the fixed rail 2. The middle rail 3 and the movable rail 4 are also movably connected, allowing the movable rail 4 to slide on the middle rail 3. One end of the movable rail 4 is fixed with an end cap 41. (Refer to...) Figure 12 One end of the end cap 41 is machined with a slot 412 and a mating surface 411. The mating surface 411 is located on the upper side of the slot 412 and is inclined. One side of the movable rail 4 is machined with a retaining edge 42 that extends outward at an angle. The retaining edge 42 is close to the end cap 41. The top surface of the movable rail 4 is machined with an insert edge 43, which is close to one end of the movable rail 4.

[0051] When the locking handle 1 is installed on the movable rail 4 of the drawer slide, such as Figure 13 and Figure 14As shown. The insert block 1311 is inserted into the slot 412 of the end cover 41. The pushing surface 1211 of the push block 121 corresponds to and abuts against the mating surface 411 of the end cover 41. The retaining edge 42 engages with the retaining groove 1411 of the locking block 141. Along... Figure 4 Move the lever 1512 in the direction of arrow C to retract the locking block 141, thereby disengaging the locking edge 42 from the locking groove 1411 and unlocking the drawer. At this time, the locking handle 1 can be removed from the moving rail 4, thereby removing the drawer from the moving rail 4.

[0052] The principle of installing a drawer on a drawer slide is as follows: The locking handle 1 is installed at the bottom of the drawer. When the drawer is installed on the movable rail 4 of the drawer slide, the insert 43 is inserted into the groove on the back of the drawer. The locking handle 1 is then installed on the movable rail 4 of the drawer slide, thus enabling the drawer to be installed on the drawer slide. Moving the lever 151 allows the drawer to be quickly removed from the drawer slide.

[0053] The principle of adjusting the height and left and right position of the drawer is as follows: rotating the first adjusting wheel 123 causes the push block 121 to move back and forth, thereby adjusting the height of the drawer; rotating the second adjusting wheel 133 causes the insert block 1311 to move left and right, thereby adjusting the left and right position of the drawer.

[0054] Compared with existing technologies, the locking handle structure of this invention is simple and practical, eliminating complex structural designs and greatly reducing processing difficulty, thereby effectively reducing manufacturing costs. At the same time, this invention enables adjustment of both drawer height and lateral position, i.e., a two-dimensional adjustable drawer. Compared to existing technologies that can only adjust drawer height, this adjustment is more flexible and convenient, better meeting the diverse needs of drawer position adjustment in actual use.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
