[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes a locking device for a drawer slide, including a first mounting plate 1; a second mounting plate 2 is used in pairs, and the second mounting plate 2 is arranged on the lower surface of the first mounting plate 1; the slide rail 3 has a first groove 301, and the slide rail 3 is arranged on one side of the second mounting plate 2; the side of the drawer 4 has a first slide groove 401, and the slide rail 3 is slidably arranged in the first slide groove 401, and the drawer 4 also has a second slide groove 402, and the second slide groove 402 is connected to the first slide groove 401; the wedge block 5 is slidably arranged in the second slide groove 402, one end of the wedge block 5 abuts against the slide rail 3, and the other end of the wedge block 5 extends out of the second slide groove 402, and after the drawer 4 drives the wedge block 5 to slide into place, one end of the wedge block 5 abuts against the first groove 301.

[0028] In this embodiment, the first mounting plate 1 is mostly a desktop, which serves as the main support component of the device, and the second mounting plate 2 is used in pairs and is installed on the lower surface of the first mounting plate 1. The function of the second mounting plate 2 is to provide support and positioning for the slide rail 3 to ensure that the slide rail 3 and the drawer 4 slide accurately and smoothly. The slide rail 3 is installed on one side of the second mounting plate 2. The shape of the slide rail 3 matches the first slide groove 401 on the side of the drawer 4 to form a sliding pair, so that the drawer 4 can slide out and push in smoothly along the slide rail 3. The drawer 4 is also provided with a second slide groove 402, and the wedge block 5 is slidably arranged in the second slide groove 402 of the drawer 4, and one end of the wedge block 5 has a specific shape that matches the structure of the first groove 301. When the drawer 4 slides, the wedge block 5 moves with the drawer 4. When the drawer 4 slides into place, one end of the wedge block 5 abuts against the first groove 301 of the slide rail 3, and the drawer 4 is locked through a specific structural match. When unlocking, the drawer 4 can be easily reset by simply pushing back the drawer 4 to disengage the wedge block 5 from the first groove 301. When the drawer 4 needs to be completely pulled out, the drawer 4 can be completely pulled out by simply pinching the end of the wedge block 5 extending out of the second slide groove 402 to prevent the wedge block 5 from contacting the first groove 301. Through the ingenious structural design, the drawer 4 can slide smoothly, lock accurately, and unlock smoothly, with the characteristics of compact structure, easy operation, safety, and reliability.

[0029] Furthermore, the first groove 301 has a first limiting surface 3011 and a first guide surface 3012, and one end of the wedge block 5 has a first contact surface 501 and a second contact surface 502. After the drawer 4 drives the wedge block 5 to slide into place, the first limiting surface 3011 abuts against the first contact surface 501, and the second contact surface 502 abuts against the first guide surface 3012.

[0030] In this embodiment, the first groove 301 on the slide rail 3 has a first limit surface 3011 and a first guide surface 3012. One end of the wedge block 5 has a first contact surface 501 and a second contact surface 502. The first contact surface 501 matches the first limit surface 3011. When the drawer 4 slides into place, the first contact surface 501 fits tightly with the first limit surface 3011 to achieve the locking of the drawer 4. The second contact surface 502 abuts against the first guide surface 3012. When the drawer 4 wants to reset, the second contact surface 502 slides along the first guide surface 3012, so that the wedge block 5 exits the first groove 301, so that the drawer 4 can be reset smoothly. This design effectively prevents the drawer 4 from accidentally sliding out, and improves the safety and reliability of the use of the drawer 4.

[0031] Furthermore, the angle between the first contact surface 501 and the second contact surface 502 is a rounded angle.

[0032] In this embodiment, the angle between the first contact surface 501 and the second contact surface 502 is designed to be rounded. The rounded corner design can reduce the stress concentration when the wedge block 5 contacts the first groove 301 of the slide rail 3, reduce wear, and increase the service life. At the same time, the rounded corner design is also conducive to reducing the noise generated during the sliding process of the drawer 4 and improving the user experience.

[0033] Furthermore, the wedge block 5 has a second groove 503 , and also includes a metal piece 6 , and the metal piece 6 is arranged inside the second groove 503 .

[0034] In this embodiment, the wedge block 5 is provided with a second groove 503 and a metal member 6, which is disposed inside the second groove 503. The main function of the metal member 6 is to increase the overall mass of the wedge block 5, so that the wedge block 5 can slide smoothly in the second slide groove 402, so that the wedge block 5 and the first groove 301 are more firmly connected, and the metal member 6 can also improve the strength of the wedge block 5.

[0035] Furthermore, the slide rail 3 is dovetail-shaped, and the first slide groove 401 is dovetail-shaped.

[0036] In this embodiment, the slide rail 3 and the first slide groove 401 are both designed as dovetail type. The dovetail type design has high guiding accuracy and load-bearing capacity, which can ensure that the drawer 4 slides stably and smoothly on the slide rail 3 and reduce shaking and jamming.

[0037] Furthermore, the first guide surface 3012 and the second contact surface 502 are both arc surfaces.

[0038] In this embodiment, the first guide surface 3012 and the second contact surface 502 are both designed as arc surfaces. The arc surface design can reduce the friction resistance when the wedge block 5 contacts the first groove 301 of the slide rail 3, making the drawer 4 smoother and reducing noise during the sliding process. At the same time, the arc surface design is also conducive to dispersing stress and improving the durability of the component.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
