[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] An embodiment of the present application discloses a left-right adjustment handle structure for a drawer slide rail.

[0035] Reference Figure 1 and Figure 2 , a left and right adjustment handle structure for a drawer slide, comprising a handle body 1, an adjusting knob 2, a movable piece 3, a sliding mechanism, a locking wrench 5 and a slide rail 6, wherein the handle body 1 is arranged on the bottom surface of the drawer 9, and the movable piece 3 covers the handle body 1. There is an accommodating cavity between the handle body 1 and the movable piece 3, which provides an installation space for the adjusting knob 2, the sliding mechanism and the locking wrench 5. At the same time, the slide rail 6 is installed on the movable piece 3, and the adjusting knob 2 serves as a driving part. When it is rotated under force, the movable piece 3 is driven to drive the slide rail 6 to slide left and right along the handle body 1, thereby realizing fine-tuning of the position of the slide rail 6 in the left and right directions. The sliding mechanism provides guidance for the left and right movement of the movable piece 3, so that the displacement of the movable piece 3 is more stable and smooth.

[0036] In the present application, the handle body 1 includes a base 11 and a handle edge 12, the handle edge 12 is fixed to one side of the base 11, and a circular avoidance groove 111 is provided on the side of the base 11 away from the movable plate 3, and the avoidance groove 111 is at least halfway through the interval. At the same time, the bottom surface of the base 11 is sunken in the area near the avoidance groove 111 to provide a recess 112, and the adjustment knob 2 is installed in the avoidance groove 111. For details, refer to Figure 3 and Figure 4 The adjusting knob 2 includes an adjusting body 21, a rotating track 22, a positioning block 23 and a gripping cover 24. The surface of the gripping cover 24 is embossed with gripping teeth 241. When installed, the gripping teeth 241 face downward and are exposed from the avoidance groove 111. The give way groove 112 partially overlaps with the avoidance groove 111. The non-overlapping part can provide the operator with more operating space, allowing the user to more conveniently rotate the adjusting knob 2 forward and reverse.

[0037] In more detail, the adjusting body 21 is fixed on the side of the gripping cover 24 away from the gripping teeth 241, the adjusting body 21 faces the inner cavity of the base 11, the rotating track 22 is fixed on the middle of the top surface of the adjusting body 21, and the movable piece 3 is movably arranged on the top of the handle body 1. The movable piece 3 includes a mating flange 31 that is concave from top to bottom. There is at least one mating flange 31, and the mating flange 31 is threadedly engaged with the rotating track 22. When there are multiple mating flanges 31, they are arranged in a line along the left and right moving directions of the movable piece 3. When the mating flange 31 is threadedly engaged with the rotating track 22, the adjacent mating flanges 31 are correspondingly engaged with the edge of the rotating track 22. Such a setting can increase the contact area between the two and achieve stable fit.

[0038] More specifically, there is at least one positioning block 23 and a grip cover 24. The positioning block 23 is fixed to one side of the grip cover 24 and is distributed outside the adjustment body 21. The positioning block 23 is fixed to the adjustment body 21. If there are multiple positioning blocks 23, they are evenly arranged along the same circumference outside the adjustment body 21, so that the positioning blocks 23 are concentric with the adjustment body 21, and the ends of the positioning blocks 23 abut against the back surface of the movable piece 3.

[0039] In specific applications, the user holds the gripping teeth 241 of the gripping cover 24 and rotates the gripping cover 24 with force. At this time, the adjustment body 21 and the positioning block 23 can rotate synchronously, and cooperate with the flange 31 to slide along the rotating track 22 to drive the movable piece 3 to move left and right. The end of the positioning block 23 abuts against the back of the movable piece 3 to ensure the stability of the entire adjustment knob 2 during the adjustment process, prevent the adjustment knob 2 from shaking or offsetting due to uneven force, and thus ensure the adjustment accuracy of the movable piece 3.

[0040] In order to further improve the moving stability of the movable sheet 3, refer to Figure 3 and Figure 4The sliding mechanism includes a first guide assembly 41, the first guide assembly 41 includes a first guide rail 411 fixed on the handle edge 12; a first guide block 412 and a second guide block 414 fixed on the back of the movable piece 3; and a second guide rail 413 fixed on the inner top surface of the base 11; wherein, the first guide block 412 and the second guide block 414 are symmetrically arranged along the central axis of the adjusting body 21, the first guide block 412 is in sliding connection with the first guide rail 411, and the second guide block 414 is in sliding connection with the second guide rail 413, and the movement directions of the first guide block 412 and the second guide block 414 are consistent, and at the same time consistent with the movement direction of the movable piece 3.

[0041] The precise coordination of the first guide rail 411, the first guide block 412, the second guide block 414, and the second guide rail 413 ensures precise guidance of the movable plate 3 during the adjustment process, effectively reducing the offset or jamming of the movable plate 3 during movement, and improving the smoothness and accuracy of the adjustment. In addition, the first guide block 412 and the second guide block 414 are symmetrically arranged along the central axis of the adjustment body 21 and slide in contact with the corresponding guide rails. This symmetrical layout not only improves the stability of the structure, but also ensures that the movable plate 3 is evenly distributed when subjected to force, reducing the risk of structural deformation or damage caused by uneven force. The movement direction of the first guide block 412 and the second guide block 414 is consistent with the movement direction of the movable plate 3, thereby ensuring the coordination and synchronization of the entire adjustment mechanism.

[0042] Furthermore, the sliding mechanism includes at least one second guide component 42, each second guide component 42 is arranged at the corner connection between the movable piece 3 and the base 11, and the second guide component 42 includes a guide slot 421 opened on the base 11; a guide column 422 fixed on the movable piece 3, wherein the extension direction of the guide slot 421 is consistent with the movement direction of the movable piece 3, and the guide column 422 is adapted to slide with the guide slot 421, which can accurately guide the movable piece 3 during the adjustment process, reduce the possible offset or shaking of the movable piece 3 during movement, improve the accuracy and stability of the adjustment, and at the same time enable the movable piece 3 to move smoothly along a predetermined trajectory during the adjustment process, effectively reducing the occurrence of jamming or blocking phenomena; the present application chooses the arrangement position of the second guide component 42 at the corner connection, which is conducive to improving the overall strength of the structure, can disperse the force to a certain extent, reduce the risk of stress concentration, and thus increase the service life and safety of the handle structure.

[0043] Furthermore, the sliding mechanism includes at least one third guide assembly 43, each positioned at the connection between the movable piece 3 and the elongated structure of the base 11. Each third guide assembly 43 comprises a retaining slot 431 formed in the movable piece 3 and a retaining post 432 secured to the base 11. The retaining slot 431 extends in the same direction as the movement of the movable piece 3, and the retaining post 432 slides in engagement with the retaining slot 431. The third guide assembly 43 provides guidance and reinforces structural strength, effectively reducing excessive movement or dislocation of the movable piece 3 during adjustment, thereby ensuring safe and reliable adjustment.

[0044] In the present application, the first guide component 41 is used to provide horizontal direction limitation for the movable piece 3 when it moves left and right, and the first guide component 41 is close to the movement area of ​​the adjusting knob 2, which is more to ensure that the torque obtained by the adjusting knob 2 is smoothly converted into the horizontal sliding of the movable piece 3; the guide column 422 of the second guide component 42 can transmit the force on the movable piece 3 to the base 11, ensuring that the movable piece 3 can also slide horizontally at the corners, reducing the tilting. At this time, the sliding force of the movable piece 3 is more fed back to the base 11 of the handle body 1, so that the movable piece 3 is evenly stressed, ensuring that the movable piece 3 always remains in a horizontal state; the limit column 432 of the third guide component 43 can further enhance the connection stability between the movable piece 3 and the base 11, especially for the connection of slender structures and special-shaped structures, and is more to ensure that there is sufficient connection between the base 11 and the movable piece 3, which can provide stable support for special-shaped structures.

[0045] The sliding mechanism of the present application adopts three guide components to achieve the limitation of each dimension in the horizontal direction, the direction from top to bottom, and the direction from bottom to top, and flexibly makes targeted limitation on the different structural coordination and different position coordination between the movable piece 3 and the handle body 1, so that the assembly of the movable piece 3 and the handle body 1 is stable, and the left and right movement effect of the movable piece 3 is best.

[0046] Reference Figure 3, an adjustment gap is formed between the side of the movable piece 3 close to the handle edge 12 and the handle edge 12. In specific application, the operator rotates the adjusting knob 2 forward, and under the threaded engagement of the mating flange 31 and the rotating track 22, the movable piece 3 is driven to approach the handle edge 12, and the adjustment gap size is reduced. Conversely, the adjustment gap size is increased. The sliding mechanism provides guidance during the movement of the movable piece 3 to ensure the movement stability of the movable piece 3, and the slide rail 6 is installed on the movable piece 3. Therefore, in the process of reducing or expanding the adjustment gap size, the position adjustment of the drawer 9 and the slide rail 6 is achieved, so that the installation process of the drawer 9 can reduce installation errors. Compared with the prior art, the present application adjusts the gap between the drawer 9 and the box body by adjusting the handle structure left and right. Compared with the operator's manual adjustment method, the former has higher adjustment accuracy, faster adjustment efficiency, better stability effect, and is more in line with installation requirements.

[0047] Reference Figure 4 and Figure 5 The handle structure of the present application also includes a locking wrench 5, a wrench connecting shaft 51 and a self-locking member 52. The locking wrench 5 is arranged between the base 11 and the movable piece 3 through the wrench connecting shaft 51. The locking wrench 5 includes a stepped plug-in portion 53 and a wrench gripping portion 54. The wrench connecting shaft 51 is arranged between the stepped plug-in portion 53 and the wrench gripping portion 54. The movable piece 3 is provided with an avoidance area near the stepped plug-in portion 53. The wrench gripping portion 54 protrudes out of the handle structure. The slide rail 6 includes a plug-in groove, and the stepped plug-in portion 53 is adapted to be plugged into the plug-in groove through the self-locking member 52.

[0048] In this application, the self-locking part 52 is a torsion spring, and the movable plate 3 is provided with a fixed clamping column 33 bent from top to bottom. The torsion spring is arranged between the fixed clamping column 33 and the wrench connecting shaft 51. One end of the torsion spring is assembled with the fixed clamping column 33 and the other end is assembled with the locking wrench 5.

[0049] During specific application, when it is necessary to unlock the position of the slide rail 6, force is continuously applied to the wrench grip 54 to make the locking wrench 5 and the slide rail 6 in a non-plugged state, and then the slide rail 6 is dragged to displace it to adjust the position of the slide rail 6; when it is necessary to lock the position of the slide rail 6, the operator applies force to the wrench grip 54 to store elastic potential energy of the torsion spring. When the plug-in slot of the slide rail 6 is aligned with the stepped plug-in portion 53 of the self-locking member 52, the force applied to the wrench grip 54 is immediately released. The elasticity of the torsion spring also enables the entire locking wrench 5 to be quickly reset, thereby achieving stable plug-in of the two. The self-locking function of the torsion spring allows the user to maintain the stable state of the locking wrench 5 without applying additional force during operation.

[0050] Reference Figure 3 and Figure 5A limit rib 32 bent from top to bottom is provided on the side of the movable piece 3 away from the handle edge 12. The limit rib 32 is used to provide a physical limit for the rotation angle of the locking wrench 5, so that the locking wrench 5 can remain stable during operation and is not prone to shaking or offset, which helps to improve the stability and accuracy of the user's operation, while reducing dust from entering the accommodating cavity, thereby protecting the structure set in the accommodating cavity.

A nut mounting groove 113 and a slider receiving groove 114 are provided on the side of the base 11 away from the movable piece 3, wherein the height adjustment slider 7 is a wedge-shaped block, and a horizontal threaded rod 71 is fixed to the middle position of the non-inclined side of the height adjustment slider 7. The horizontal threaded rod 71 is threadedly connected to the control nut 8. The control nut 8 is placed in the nut mounting groove 113, and the height adjustment slider 7 is placed in the slider receiving groove 114. At the same time, the end of the height adjustment slider 7 away from the control nut 8 is abutted against the slide rail 6, that is, the end of the height adjustment slider 7 with the inclined surface is abutted against the slide rail 6, so that the height adjustment slider 7 and the slide rail 6 fit tightly and the force is evenly distributed.

[0052] By providing the nut mounting groove 113 and the slider receiving groove 114, the height adjustment slider 7 and the control nut 8 can be correspondingly hidden in specific areas inside the base 11, maintaining the neatness and beauty of the product appearance. In addition, the user only needs to rotate the control nut 8 to quickly adjust the height of the slide rail 6, thereby improving the applicability and flexibility of the product.
