Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, in an embodiment of the present utility model, a sliding door track includes a shielding door body 1, a slider 3 is installed below the shielding door body 1, and a hollow portion 31 is provided in the middle of the slider 3;

as shown in fig. 1 and 2, the shielding door further comprises a track rod 2, the track rod 2 passes through the hollow part 31, the lower surface of the sliding block 3 is provided with a wheel groove 6, the inside of the wheel groove 6 is provided with a roller 4, the lower surface of the roller 4 protrudes out of the lower surface of the sliding block 3, when the shielding door main body 1 moves, the sliding block 3 can slide on the track rod 2, and as only the outer surface of the track rod 2 has dust, the outer surface of the track rod 2 can be cleaned directly during cleaning, the cleaning is more convenient, the condition that deposited dust is difficult to clean is avoided, the sliding of the sliding block 3 is convenient, the roller 4 can roll on the ground directly, the roller 4 can be supported by the ground, the track rod 2 only plays a guiding role, the bearing role is not played, and the service life of the track rod 2 is prolonged;

as shown in fig. 3 and 4, the wheel shafts 5 are fixed to both ends of the roller 4;

referring to fig. 4 and 5, a bearing seat 7 is rotatably installed at one end of the wheel shaft 5 far away from the roller 4, vertical sliding grooves 9 are formed in positions, corresponding to the bearing seat 7, of two sides of the sliding block 3, the bearing seat 7 can slide in the sliding grooves 9, fault tolerance of the installation height of the roller 4 can be increased, and installation is convenient;

with continued reference to fig. 4 and 5, a spring 8 is fixed on the upper surface of the bearing seat 7, the upper end of the spring 8 is mounted on the top surface of the chute 9, the spring 8 can give an upward thrust to the sliding block 3, and further the sliding block 3 is lifted upwards, so that the bearing of the track rod 2 is further reduced, and the service life of the track rod 2 is further prolonged;
