Description

Technical Field

[0001] This utility model belongs to the field of hardware accessories, and in particular relates to a sliding door hanging wheel. Background Technology

[0002] Trolleys are a key component of sliding doors. They are typically installed within the track and rely on the track to support the weight of the door panel for sliding. To prevent the trolleys from falling off the track, positioners are usually installed at the ends of the track. Traditional positioner installation requires drilling holes in the track, inserting the positioner into the drilled holes, and ensuring it is secure. This method is relatively cumbersome, and the position of the positioner cannot be easily moved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a more convenient anti-fall sliding door hanging wheel mechanism.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: a hanging rail and a slidable hanging wheel disposed in the hanging rail. The hanging rail is provided with a groove adapted to the hanging wheel, and a snap-fit ​​groove is provided above the groove. A hanging wheel anti-fall device is provided in the snap-fit ​​groove. The hanging wheel anti-fall device includes a positioning block, a pointed fastening screw, and a nut. The upper end of the positioning block is installed in the snap-fit ​​groove through positioning steps on both sides, and the lower end is provided with a blocking surface that extends into the groove. The nut is embedded in a nut mounting groove at the upper end of the positioning block. The pointed fastening screw is connected to the nut through a screw hole in the blocking surface, and the pointed tip of the pointed fastening screw abuts against the upper end of the snap-fit ​​groove. The front end of the hanging wheel is provided with an impact part that cooperates with the blocking surface.

[0005] The blocking surface is L-shaped.

[0006] The positioning step surface of the positioning block is provided with a wavy pattern.

[0007] The upper end of the snap-fit ​​groove is provided with a conical positioning groove, and the tip of the pointed fastening screw abuts against the conical positioning groove.

[0008] The side wall of the nut mounting groove is provided with a set of retaining ribs, and the upper end of the retaining ribs is provided with an inclined surface. The nut is fixed in the nut mounting groove by the retaining ribs.

[0009] The advantages of the anti-fall sliding door hanging wheel mechanism of this utility model are as follows: no drilling is required, installation is more convenient, and it has good stability.

[0010] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0012] Reference Figure 1-7 As shown, the anti-fall sliding door roller mechanism of this utility model includes a rail 1 and a roller 2 slidably disposed within the rail 1. The roller 2 is connected to the sliding door via a connecting box 20 at its lower end. The rail 1 has a groove 3 adapted to the roller 2, and a locking groove 4 is provided above the groove 3 on the rail 1. The locking groove 4 contains a roller anti-fall device 5, which includes a positioning block 6, a pointed fastening screw 7, and a nut 8. The upper end of the positioning block 6 is installed in the locking groove 4 via positioning steps 9 on both sides. The lower end of the positioning block 6 has a blocking surface 10 extending into the groove 3. The nut 8 is embedded in a nut mounting groove 11 at the upper end of the positioning block 6. The pointed fastening screw 7 is connected to the nut 8 through a screw hole 12 in the blocking surface 10, and the pointed tip 13 of the pointed fastening screw 7 abuts against the upper end of the locking groove 4. When the pointed fastening screw 7 is tightened, the positioning block 6 moves in the opposite direction to achieve a tight connection with the locking groove 4. The front end of the hanging wheel 2 is provided with an impact part 14 that cooperates with the blocking surface 10. When the hanging wheel 2 slides to its limit position, the impact part 14 impacts the blocking surface 10 to achieve positioning of the sliding door.

[0013] Preferably, the blocking surface 10 is L-shaped, which can more closely match the positioning of the impact part 14.

[0014] Preferably, the positioning step 9 of the positioning block 6 is provided with a corrugated pattern 15, which contacts the inner wall of the snap-fit ​​groove 4 to increase friction and thus improve the stability of the hanging wheel anti-fall device 5.

[0015] Preferably, the upper end of the snap-fit ​​groove 4 is provided with a conical positioning groove 16, and the tip 13 of the pointed fastening screw 7 abuts against the conical positioning groove 16. This achieves positioning of the pointed fastening screw 7, thereby improving the stability of the connection.

[0016] Preferably, the side wall of the nut mounting groove 11 is provided with a set of retaining ribs 18, and the upper end of the retaining ribs 18 is provided with an inclined surface 19. The nut 8 is fixed in the nut mounting groove 11 by the retaining ribs 18. With the above structure, it is convenient to insert the nut 8 into the nut mounting groove 11 and fix it.

[0017] As stated above, this is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
