[0004] In view of the deficiencies of the prior art, the utility model provides a three-rail three-linkage tool cabinet sliding door. The three-door design enables users to open or close different numbers of doors simultaneously according to needs, facilitating quick access to tools. Moreover, the bottom of the door body is distributed in a stepped manner and is provided with bosses to prevent external dust and rainwater from entering the interior of the tool cabinet.
[0005] The utility model is realized through the following technical solutions. A three-rail three-linkage tool cabinet sliding door is provided, which includes a first door body, a second door body, and a third door body arranged in sequence from front to back. The bottoms of the first door body, the second door body, and the third door body are distributed in a stepped manner from high to low. One side of the second door body and the third door body are respectively provided with a first track member and are slidably connected to the bottoms of the first door body and the second door body. The bottom of the door frame of the tool cabinet is provided with a second track member slidably connected to the bottom of the third door body.
[0006] The sliding door in this solution is composed of a first door body, a second door body, and a third door body to form a three-door structure, and each door can slide. This modular design greatly improves the space utilization rate when taking and placing items. The first door body is slidably connected to the second door body through the first track member, the second door body is slidably connected to the third door body through the first track member, and the third door body is slidably connected to the door frame through the second track member. Each door body is connected through its respective track member, significantly increasing the opening area at the front of the cabinet body, enabling users to access the internal storage space more directly and conveniently. And the bottoms of the first door body, the second door body, and the third door body are distributed in a stepped manner, facilitating the connection and installation of each door body to its respective track member, and making it more convenient to use.
[0007] As an optimization, the first track member includes a horizontal support plate and a vertical first slide rail. The support plate is fixedly connected to the side wall of the second door body or the third door body. The first slide rail is fixedly connected to the top of the support plate. Sliding grooves adapted to the first slide rail are provided at the bottoms of the first door body and the second door body. In this optimized solution, the door bodies are supported by the support plate, and the door bodies slide along the first slide rail on the support plate through the sliding grooves at the bottoms. At the same time of sliding, a limiting function is achieved, making the sliding of the door bodies and the first track member more stable.
[0008] As an optimization, the second track member is a vertical second slide rail. The second slide rail is fixedly connected to the bottom of the door frame. A sliding groove adapted to the second slide rail is provided at the bottom of the third door body. In this optimized solution, the third door body also slides along the second slide rail through the sliding groove, improving the sliding stability of the third door body.

In this optimized solution, the upper ends of the door bodies can also slide smoothly, making the pushing and pulling of the door bodies more smooth.
[0010] As an optimization, the upper track member includes a mounting plate fixedly connected to the top of the door frame, and three L-shaped guide rails fixedly connected to the bottom of the mounting plate. The three guide rails are arranged front and back, and the first door body, the second door body, and the third door body are respectively slidably connected to the three guide rails.
[0011] As an optimization, pulley members are fixedly provided at the tops of the first door body, the second door body, and the third door body. The pulley members are slidably connected to the horizontal sides of the guide rails. In this optimized solution, the frictional resistance during door pushing is effectively reduced, making the door pushing operation easier and smoother. At the same time, the wear between the door pushing and the slide rails is reduced, extending the service life.
[0012] As an optimization, a limiting protrusion adapted to engage with the roller of the pulley member is provided on the upper end surface of the horizontal side of the guide rail, and a limiting groove adapted to engage with the limiting protrusion is provided on the outer circumferential surface of the roller. In this optimized solution, through the engagement of the limiting protrusion and the limiting groove, a guiding and limiting function is exerted on the pulley member, preventing the pulley member from disengaging from the guide rail.
[0013] As an optimization, a first linkage plate for driving the second door body to slide left and right is provided on the first door body, and a second linkage plate for driving the third door body to slide left and right is provided on the second door body. The first linkage plate and the second linkage plate are arranged on the same side. In this optimized solution, the left and right linkage movement of the three door bodies is realized through the first linkage plate and the second linkage plate, making it more convenient to use. The first linkage plate and the second linkage plate have a limiting function, preventing the door bodies from sliding out of the first track member and ensuring the stability of the sliding of the door bodies.
[0014] As an optimization, a boss is provided at the bottom of the door frame directly below the first door body. The boss extends along the length direction of the door frame and the top of the boss is higher than the bottom of the second door body. This optimization solution blocks external dust and rainwater from entering the interior of the tool cabinet through the boss.
[0015] The beneficial effects of the present utility model are as follows: The push-pull door of the present utility model adopts a three-door structure design of three door bodies.
