Description

Technical Field

[0001] The utility model belongs to the technical field of door handles, and particularly relates to a new type of fastening handle. Background Art

[0002] Most of the fixing methods of traditional handles adopt the mother-son screw fixing system, that is, it consists of a smaller screw on one side of the handle and a larger nut on one side of the door panel. The son screw is usually conical and is used to pass through the small hole on the handle and then cooperate with the mother nut on the back of the door panel to realize the fixing of the handle. The defect of the above fixing method is that the fastening force of the conical small screw is weak. Especially after long-term use, due to repeated pulling, the screw is likely to gradually loosen or even fall off, and the loss of the small screw is a common problem. Once lost, the repair process may be more troublesome and it is necessary to find a matching replacement part. Summary of the Invention

The inner walls of the fixed sleeve and the fastening sleeve are both provided with internal threads, and the internal threads are adapted to the studs. The fixed sleeve and the fastening sleeve are respectively installed on the two handles through one stud, and the other stud is a connecting stud. The end of the fastening sleeve is also provided with a stepped inner hole, and the stepped inner hole coincides with the axis of the fastening sleeve. A connecting sleeve is arranged at the end of the fastening sleeve. The end of the connecting sleeve is connected with a limiting circular plate through a short column, the short column extends into the stepped inner hole, and the limiting circular plate is located in the stepped inner hole. The connecting sleeve is provided with a threaded inner hole, and the outer shape of the connecting sleeve is a prism structure. The movable sleeve has a prismatic inner hole adapted to the outer shape of the connecting sleeve, and the connecting sleeve is located in the prismatic inner hole of the movable sleeve;

[0007] A perforation is formed on the door panel, the connecting stud is inserted into the perforation, and one end of the connecting stud is threadedly connected in the fixed sleeve, and the other end of the connecting stud extends into the prismatic inner hole and is connected in the threaded inner hole of the connecting sleeve.

[0008] Further, two gaskets are sleeved on the connecting stud, and the two gaskets are located on both sides of the door panel.

[0009] Further, the end of the stud has an internal hexagonal groove.

[0010] Furthermore, the outer wall of the movable sleeve has a milled flat surface.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The following further describes the present utility model in detail in conjunction with embodiments.

[0024] Specific Embodiment 1 of a new type of fastening handle provided by the present utility model:

[0025] As Figure 1 shown, a new type of fastening handle includes two handles 1. The handles 1 are the parts directly contacted by users and are used to open or close the door panel 2. The two handles 1 are respectively installed on both sides of the door panel 2 through two groups of fastening connectors;

[0026] As Figures 2 - 9 shown, the fastening connector includes a fixed sleeve 3, a movable sleeve 4, a fastening sleeve 5 and three studs 6. The inner walls of the fixed sleeve 3 and the fastening sleeve 5 are both provided with internal threads, and the internal threads are adapted to the studs 6. The fixed sleeve 3 and the fastening sleeve 5 are respectively installed on the two handles 1 through a stud 6. The other stud 6 is a connecting stud 7, and the connecting stud 7 is used to connect the fixed sleeve 3 and the fastening sleeve 5. As Figure 5 and Figure 6 shown, the end of the fastening sleeve 5 is further provided with a stepped inner hole 8, and the stepped inner hole 8 coincides with the axis of the fastening sleeve 5. A connecting sleeve 9 is provided at the end of the fastening sleeve 5. The end of the connecting sleeve 9 is connected with a limiting circular plate 13 through a short column 11. The short column 11 extends into the stepped inner hole 8, and the limiting circular plate 13 is located in the stepped inner hole 8. The setting of the limiting circular plate 13 prevents the connecting sleeve 9 from disengaging from the end of the fastening sleeve 5. The connecting sleeve 9 can freely rotate at the end of the fastening sleeve 5 through the short column 11 and the limiting circular plate 13. A threaded inner hole 14 is provided on the connecting sleeve 9, and the outer shape of the connecting sleeve 9 is a hexagonal prism structure. As Figure 7 and Figure 8 shown, the movable sleeve 4 has a prismatic inner hole 15 adapted to the outer shape of the connecting sleeve 9, and the connecting sleeve 9 is located in the prismatic inner hole 15 of the movable sleeve 4;

[0027] A perforation is provided on the door panel 2. The connecting stud 7 is inserted into the perforation, and one end of the connecting stud 7 is threadedly connected in the fixed sleeve 3. The other end of the connecting stud 7 extends into the prismatic inner hole 15 and is then connected in the threaded inner hole 14.

[0028] When installing the new type of fastening handle in this embodiment, first, install the two studs 6 on the two handles 1. Preferably, an internal hexagonal groove 16 is provided at the end of the stud 6 to facilitate the use of an internal hexagonal wrench for screwing and installing. Then, screw and fix the fixed sleeve 3 and the fastening sleeve 5 on the two studs 6; then insert the connecting stud into the perforation on the door panel 2, and install gaskets 10 at both ends of the connecting stud. Then, use an internal hexagonal wrench to screw the connecting stud 7 and screw it into the fixed sleeve 3; then align the prismatic inner hole 15 of the movable sleeve 4 with the end of the connecting stud 7, rotate the movable sleeve 4, so that the connecting sleeve 9 rotates, and install the connecting sleeve 9 on the connecting stud 7 by screwing to complete the installation.

[0029] The setting of the gasket 10 avoids the direct contact between the fixed sleeve 3 and the movable sleeve 4 and the door panel 2, disperses the pressure, and avoids damage to the door panel 2; preferably, as Figure 8 shown, a milling plane 12 can be provided on the outer wall of the movable sleeve 4, which is convenient for using a wrench to hold the milling plane to rotate the movable sleeve 4.

[0030] It should be noted that in this article, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
