[0034] Reference Figures 1 to 6 A drawer mechanism includes a drawer body 100, a guide rail 200, a mounting screw 310 and a pressure block 320. The guide rail 200 is provided with two and slides with the left and right sides of the drawer body 100 respectively. The side of the guide rail 200 is provided with a mounting hole 201. The mounting screw 310 has a head 311 and a rod 312. The rod 312 of the mounting screw 310 passes through the pressure block 320 and the mounting hole 201 and is used to cooperate with the external thread. The pressure block 320 is located at Between the head 311 of the mounting screw 310 and the guide rail 200, a toothed surface 321 is provided on the side of the pressure block 320 facing the guide rail 200 and on the side of the guide rail 200 facing the pressure block 320. The mounting screw 310 can move relative to the mounting hole 201 along the radial direction of the rod 312. The head 311 of the mounting screw 310 can press the pressure block 320 onto the guide rail 200 so that the pressure block 320 and the guide rail 200 are in contact with each other through the toothed surface 321.

[0035] It is understandable that if Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the guide rail 200 is a long strip structure extending in the front-to-back direction. The two guide rails 200 are respectively slidably matched with the left and right sides of the drawer body 100. The outer periphery of the mounting hole 201 is provided with an uneven toothed surface 321. The side of the pressure block 320 facing the mounting hole 201 is also provided with an uneven toothed surface 321. The pressure block 320 is annular to allow the rod 312 of the mounting screw 310 to pass through. When installing, refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The rod 312 of the mounting screw 310 passes through the pressure block 320 and the mounting hole 201 and is threadedly engaged with the threaded hole or threaded member on the cabinet wall. First, loosen the mounting screw 310. Since the mounting screw 310 can move relative to the mounting hole 201 along the radial direction of the rod 312, the guide rail 200 can be operated to move relative to the mounting screw 310 to adjust the installation position of the guide rail 200. After the adjustment is completed, tighten the mounting screw 310. The head 311 of the mounting screw 310 presses the pressure block 320 against the guide rail 200, so that the pressure block 320 and the guide rail 200 abut against each other through the toothed surface 321, thereby achieving relative fixation between the two and fixing the installation position of the guide rail 200. The guide rails 200 on both sides can be adjusted in the installation position through the above structure, which is conducive to ensuring that the guide rails 200 on both sides are parallel and on the same horizontal plane, which is conducive to the subsequent installation of the drawer body 100 and the smooth operation of the drawer.

[0036] In actual application, the mounting screws 310 may be bolts or screws, and the specific structures of the drawer body 100 and the guide rail 200 may be set accordingly according to actual use requirements.

[0037] In some embodiments, the mounting hole 201 is a circular hole and the diameter of the mounting hole 201 is larger than the diameter of the rod 312 of the mounting screw 310. Figure 3 and Figure 4 As shown, mounting hole 201 is a circular hole with a diameter larger than the diameter of the shaft 312 of mounting screw 310. This allows mounting screw 310 to move up and down, forward and backward relative to mounting hole 201, facilitating adjustment of the installation position of guide rail 200 and facilitating ease of use. In actual applications, in addition to the above structure, mounting hole 201 can also be a strip-shaped hole, allowing mounting screw 310 to move along the strip-shaped extension direction of mounting hole 201. The specific configuration can be modified according to actual needs.

[0038] In some embodiments, the drawer mechanism also includes an eccentric block 330, which is arranged in the mounting hole 201 and adapted to the mounting hole 201. The eccentric block 330 can rotate relative to the mounting hole 201. The eccentric block 330 is provided with a through hole 331 for the rod 312 of the mounting screw 310 to pass through. The through hole 331 is eccentrically arranged relative to the rotation axis of the eccentric block 330.

[0039] It is understandable that if Figure 3 、 Figure 4 and Figure 6 As shown, the outer contour of the eccentric block 330 is a circle that is adapted to the mounting hole 201. When the eccentric block 330 is arranged in the mounting hole 201, its outer peripheral wall contacts the hole wall of the mounting hole 201. The eccentric block 330 can be rotated relative to the mounting hole 201 through clearance fit or transition fit. The through hole 331 is eccentrically arranged relative to the rotation axis of the eccentric block 330. During installation, the rod 312 of the mounting screw 310 passes through the eccentric block 330 through the through hole 331. By rotating the eccentric block 330, the position of the mounting screw 310 relative to the mounting hole 201 can be adjusted. Due to the setting of the eccentric block 330, it fills the gap between the outer periphery of the rod 312 of the mounting screw 310 and the hole wall of the mounting hole 201, which can play a certain supporting effect, which is beneficial to improving the stability of the structure and is easy to use. In actual application, in order to facilitate the operation of the eccentric block 330, an operation hole can be set on the eccentric block 330. The operation hole can be inserted into an external component to drive the eccentric block 330 to rotate. The eccentric block 330 can be set accordingly according to actual use needs.

[0040] In some embodiments, the head 311 of the mounting screw 310 can press the pressing block 320 against the eccentric block 330 to limit the rotation of the eccentric block 330. Figure 3 、 Figure 4 and Figure 6 As shown, after adjusting the position of the guide rail 200, tighten the mounting screw 310 so that the head 311 of the mounting screw 310 presses the pressure block 320 toward the eccentric block 330 to limit the rotation of the eccentric block 330, thereby improving the stability and reliability of the structure and facilitating its use. In actual use, the side of the eccentric block 330 facing the pressure block 320 can be provided with anti-slip grooves to achieve a better rotation-limiting effect. The pressure block 320 can be made of an elastic material, such as rubber or silicone, to achieve a better squeezing and fixing effect. The specific material can be changed according to actual use needs.

[0041] In some embodiments, mounting holes 201 are provided at both ends of the guide rail 200 along the sliding direction of the drawer body 100 , and a mounting screw 310 and a pressing block 320 are correspondingly provided at each mounting hole 201 .

[0042] It is understandable that if Figure 1 、 Figure 2and Figure 3 As shown, the drawer body 100 slides in the front-to-back direction. The guide rail 200 is provided with mounting holes 201 at both the front and rear ends. Each mounting hole 201 is provided with a mounting screw 310, a pressure block 320, and an eccentric block 330. This allows both ends of the guide rail 200 to be adjusted, thereby effectively adjusting and fixing the mounting position of the guide rail 200 for ease of use. In actual use, the specific arrangement of the mounting holes 201, mounting screws 310, pressure blocks 320, and eccentric blocks 330 can be adjusted accordingly according to actual needs.

[0043] In some embodiments, pulleys 110 are rotatably connected to the left and right sides of the drawer body 100 , and the drawer body 100 is slidably engaged with the guide rails 200 via the pulleys 110 .

[0044] It is understandable that if Figure 2 、 Figure 5 and Figure 6 As shown, pulleys 110 are rotatably connected to the left and right sides of the drawer body 100. Two pulleys 110 are provided on each side and spaced apart in the front-to-back direction. The drawer body 100 slides with the guide rail 200 via the pulleys 110 to enable the drawer body 100 to slide back and forth relative to the guide rail 200. This structure is simple, the relative motion friction is low, and it is easy to use. In actual application, in addition to the above structure, the drawer body 100 and the guide rail 200 can also be slidably connected by a slider and a slide groove, and the specific structure can be changed accordingly according to actual use needs.

[0045] In some embodiments, a rail portion 210 is provided on the guide rail 200 to cooperate with the pulley 110 . The rail portion 210 extends along the movement direction of the drawer body 100 . An annular groove 111 is provided on the circumference of the pulley 110 for the rail portion 210 to be inserted into.

[0046] It is understandable that if Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the pulley 110 is provided with an annular groove 111 along its circumferential side in the direction of rotation. The rail portion 210 extends in the front-to-back direction and engages with the annular groove 111 of the pulley 110. The pulley 110 is limited in the left and right directions by the engagement of the annular groove 111 and the rail portion 210. This helps prevent left and right deviation during the forward and backward movement of the drawer body 100, improves the stability and reliability of the movement, and facilitates use. In actual application, in addition to the above structure, the guide rail 200 may also be provided with a guide groove extending in the front-to-back direction. The pulley 110 rolls in the guide groove to guide its forward and backward movement and prevent deviation. The specific structure of the rail portion 210 and the annular groove 111 can be set accordingly according to actual use needs.

[0047] In some embodiments, the rail portion 210 is located at the lower side of the pulley 110, and the guide rail 200 is provided with a baffle 220 above the pulley 110. It is understood that if Figure 3 、 Figure 4 and Figure 5 As shown, the rail portion 210 is located at the lower side of the pulley 110 to support the pulley 110. A baffle 220 is provided above the pulley 110. On the one hand, the baffle 220 may block the movement of the pulley 110 in the up and down directions to prevent foreign objects from falling into the movement trajectory and affecting the movement of the pulley 110. On the other hand, the baffle 220 can limit the upward movement of the pulley 110, which is beneficial to prevent the pulley 110 from derailing, improve the reliability of the movement, and facilitate use.

[0048] In actual application, in order to facilitate the installation of the drawer body 100, refer to Figure 3 and Figure 4 The baffle 220 may be provided with a notch for the pulley 110 to pass through, so that the pulley 110 can be installed under the baffle 220 through the notch and cooperate with the rail portion 210. The specific structure of the baffle 220 can be set accordingly according to actual use needs.

[0049] In some embodiments, the guide rail 200 is provided with a limit portion 230 for limiting the movement of the pulley 110. It is understood that if Figure 3 、 Figure 4 and Figure 6 As shown, each guide rail 200 is provided with two stoppers 230. The two stoppers 230 on the same guide rail 200 are spaced apart along the front-to-back direction at both ends of the motion trajectory of the pulley 110. These stoppers 230 block the pulley 110, thereby limiting the motion of the pulley 110. This helps prevent excessive motion of the pulley 110 and ensures stable and reliable forward and backward sliding of the drawer body 100. In actual application, the specific structure of the stoppers 230 can be set accordingly according to actual use needs.

[0050] The cabinet according to the second embodiment of the present invention includes the drawer mechanism according to the first embodiment of the present invention.

[0051] The cabinet according to the embodiment of the present invention adopts the above-mentioned drawer mechanism, which helps to ensure that the guide rails 200 on both sides are parallel and on the same horizontal plane, which is beneficial to the installation of the drawer body 100 and ensures that the drawer runs smoothly and is easy to use.

[0052] Since other components of the cabinet in the embodiment of the present invention are known to those skilled in the art, they will not be described in detail here.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
