[0034] See also Figure 1-Figure 8 , which is a schematic diagram of a three-section hidden rail drawer structure with handle adjustment provided in one embodiment of the utility model, the three-section hidden rail drawer structure with handle adjustment includes a guide rail mechanism 100 and a transmission mechanism 200, wherein:

[0035] In order to replace the connection method between the drawer and the cabinet body only through guide rails and rollers, and to avoid the phenomenon that the rollers and guide rails fall off when the drawer is pulled out, thereby affecting the use, a method of using three-section hidden rails to connect the cabinet body and the drawer is proposed, and a transmission mechanism 200 is set between the three-section hidden rails to realize the pulling out of the drawer.

[0036] In order to achieve a stable connection between the drawer and the cabinet, the guide rail assembly includes a primary rail body 110 connected to the cabinet at one end, a secondary rail body 120 clamped on the end of the primary rail body 110 away from the cabinet, and a tertiary rail body 130 sleeved on the secondary rail body 120. This structure eliminates the support frame structure and directly uses the primary rail body 110 to replace the support frame to connect the cabinet, and supports the secondary rail body 120 and the tertiary rail body 130, so that the secondary rail body 120 and the tertiary rail body 130 can slide on the primary rail body 110, thereby improving the stability of the support.

[0037] In this embodiment, the primary rail body 110, the secondary rail body 120, and the tertiary rail body 130 are all C-shaped guide rails, and the secondary rail body 120 is directly sleeved on the end of the primary rail body 110 away from the cabinet, so that the end of the primary rail body 110 away from the cabinet is directly clamped in the secondary rail body 120, and in order to avoid direct contact between the primary rail body 110, the secondary rail body 120, and the tertiary rail body 130, a first support member 510 is provided between the primary rail body 110 and the secondary rail body 120, and a second support member 520 is provided between the secondary rail body 120 and the tertiary rail body 130. A right-angle embedding groove is provided inside the first support member 510 along its length direction, and the end of the primary rail body 110 away from the cabinet is provided in the right-angle embedding groove, and the secondary rail body 120 is completely sleeved on the outside of the first support member 510, thereby strengthening the connection stability between the primary rail body 110 and the secondary rail body 120, and preventing the two from falling off easily. The first type of stoppers 112 are provided at both ends of the primary rail body 110 to prevent the first support member 510 from falling off when sliding along the length direction of the primary rail body 110. Similarly, the second type of stoppers 122 are also provided inside the secondary rail body 120 to prevent the first support member 510 from falling off therefrom.

[0038] A plurality of second support members 520 are sleeved on the outside of the secondary rail body 120, and the second support members 520 are distributed outside the secondary rail body 120 to support the primary rail body 110. At the same time, a plurality of second-type stoppers 122 are also provided at both ends and the external end surface of the secondary rail body 120 to prevent the second support members 520 from directly sliding off the secondary rail body 120 when the tertiary rail body 130 slides outside the secondary rail body 120. At the same time, a third-type stopper 132 is also provided at both ends of the tertiary rail body 130. The third-type stopper 132 restricts the second support members 520, and the second-type stopper 122 restricts the primary rail body 110 from sliding off the outside of the secondary rail body 120 when the primary rail body 110 slides along its length direction. At the same time, the primary rail body 110 is clamped outside the secondary rail body 120 to prevent the primary rail body 110 and the secondary rail body 120 from falling off in a direction perpendicular to the sliding direction.

[0039] Based on the above stable structure, a transmission mechanism 200 is further provided between the primary rail body 110, the secondary rail body 120 and the tertiary rail body 130. The transmission mechanism 200 includes a lower branch rail 210 provided outside the primary rail body 110, an upper branch rail 220 provided inside the tertiary rail body 130, and a transmission wheel 230 provided between the lower branch rail 210 and the upper branch rail 220.

[0040] In order to install the lower rail 210, a plurality of lower rail mounting holes 111 are evenly opened on the side of the primary rail body 110 away from the cabinet body, and a plurality of lower hook frames 211 are extended in the direction of the drawer pulling out from the side of the lower rail 210 close to the primary rail body. When installing the lower rail 210, the lower hook frames 211 are inserted into the lower rail mounting holes 111 and moved in the direction of the drawer pulling out until the lower hook frames 211 are clamped in the lower rail mounting holes 111. If the drawer pulling out length needs to be adjusted, the number of lower rail mounting holes 111 can be set to be greater than the number of lower hook frames 211, and the drawer pulling out length can be adjusted by adjusting the installation position of the lower rail 210.

[0041] Similarly, in order to install the upper rail 220, a plurality of upper rail mounting holes 131 are evenly opened on the side of the three-stage rail body 130 away from the cabinet body, and a plurality of upper hook frames 221 are extended from the side of the upper rail 220 away from the cabinet body in the direction of pushing the drawer in. When installing the upper rail 220, the upper hook frame 221 is inserted into the upper rail mounting hole 131 and moved in the direction of pushing the drawer in until the upper hook frame 221 is clamped in the upper rail mounting hole 131. If it is necessary to adjust the pull-out length of the drawer, a number of upper rail mounting holes 131 greater than the number of upper hook frames 221 can be set, and the pull-out length of the drawer can be adjusted by adjusting the installation position of the upper rail 220.

[0042] In order to realize the transmission function, a transmission wheel 230 hole 121 is provided on the secondary rail body 120, and the upper and lower ends of the transmission wheel 230 are respectively meshed and connected with the upper support rail 220 and the lower support rail 210, and the transmission wheel 230 rolls on the upper support rail 220 and the lower support rail 210 to realize smooth drawing and pulling of the drawer. It is worth noting that the transmission wheel 230 is arranged between the first support members 510 to limit the transmission wheel 230 and prevent it from derailing from the upper support rail 220 or the lower support rail 210, resulting in failure of the transmission function.

[0043] Furthermore, a stopper 300 and a fine-adjustment handle 400 are respectively provided at both ends of the three-stage rail body 130. The stopper 300 can be connected to the tail of the three-stage rail body 130 by welding or clamping, so as to abut against the tail of the drawer. The fine-adjustment handle 400 is used to adjust the left and right distance of the drawer. The fine-adjustment handle 400 is clamped on the port of the three-stage rail body 130, and the rotating part on the fine-adjustment handle 400 is rotated, thereby driving the three-stage rail body 130 to fine-adjust the distance between the drawer and the cabinet body by clamping the fulcrum.

[0044] In summary, according to a three-section hidden rail drawer structure with handle adjustment provided by the utility model, one end of the primary rail body is connected to the cabinet body, and the other end is embedded in the secondary rail body, and the secondary rail body slides on the primary rail body. At the same time, the tertiary rail body is connected to the drawer and sleeved on the secondary rail body, and the lower support rail, upper support rail and transmission wheel arranged between the primary rail body and the third rail body slide to achieve silky movement between the drawer and the cabinet body, replace the connection structure of the transmission roller and the guide rail, and improve the stability between the drawer and the cabinet body. Specifically, the guide rail mechanism includes a primary rail body connected to the cabinet body at one end, a secondary rail body clamped on the end of the primary rail body away from the cabinet body, and a tertiary rail body sleeved on the secondary rail body, and the tertiary rail body is connected to the drawer. The transmission mechanism includes a lower support rail arranged outside the primary rail body, an upper support rail arranged inside the tertiary rail body, and a transmission wheel arranged between the lower support rail and the upper support rail. The primary rail body, the secondary rail body and the tertiary rail body are embedded or sleeved in sequence to improve the stability of the structure, and the preset pulling performance is achieved through the transmission performance of the upper support rail, the lower support rail and the transmission wheel.
