This embodiment provides a hardware mounting structure configured to mount a hardware transmission assembly in a groove of a profile. As shown in FIGS. 1 to 3, the hardware mounting structure includes a base 1, a rotation part 2, and an elastic piece 3. It is to be noted that the base 1 is only an exemplary structure in this embodiment, and the base 1 may be a part of a lock rod on a door and window, a transmission rod on a transmission casing, or a rod-like transmission part on a hinge, or a part connected to it.
In some examples, the base 1 is provided with an accommodation groove 11 and a first boss 12. The rotation part 2 is disposed in the accommodation groove 11 and rotatably connected to the base 1. The rotation part 2 includes a locking piece 21 (as shown in FIG. 4). Two ends of the locking piece 21 can protrude out of the accommodation groove 11 when the rotation part 2 rotates. A first end of the elastic piece 3 is installed on the first boss 12, and a second end of the elastic piece 3 can abut against a side surface of the locking piece 21, so as to limit rotation of the locking piece 21.
In some examples, the elastic piece 3 is configured to limit the rotation of the locking piece 21 when the two ends of the locking piece 21 protrude out of the accommodation groove 11.
In some examples, the locking piece 21 has an initial state and a protruding state. When the locking piece 21 is in the initial state, the locking piece 21 is completely disposed in the accommodation groove 11 and does not protrude out of the accommodation groove 11. When the locking piece 21 is in the protruding state, the two ends of the locking piece 21 protrude out of the accommodation groove 11.
As shown in FIG. 3, in this embodiment, the first boss 12 protrudes from a bottom surface of the base 1. The bottom surface of the base 1 and one side surface of the first boss 12 define the accommodation groove 11, and the bottom surface of the base 1 and the one side surface of the first boss 12 are inner walls of the accommodation groove 11.
It is to be understood that the two ends of the locking piece 21 capable of protruding out of the accommodation groove 11 means that the two ends of the locking piece 21 can protrude outward relative to circumferential side surfaces adjacent to the bottom surface of the base 1.
As shown in FIGS. 1 to 8, during mounting, the hardware mounting structure is placed in a groove of a frame body profile 100 or a leaf body profile 100, the rotation part 2 is rotated on the base 1, the rotation part 2 drives the locking piece 21 to rotate together, and the two ends of the locking piece 21 protrude out of the accommodation groove 11 to be engaged with the groove of the profile 100, so as to complete the mounting. Moreover, one end of the elastic piece 3 is pressed upon the locking piece 21, where the elastic piece 3 is installed on the first boss 12; during the rotation of the locking piece 21, under an elastic force of the elastic piece 3, the one end of the elastic piece 3 gradually switches to abut against the side surface of the locking piece 21, so as to limit the rotation of the locking piece 21. This structure has a self-locking function.
To ensure that the locking piece 21 in the initial state is completely disposed in the accommodation groove 11, optionally, the width of the locking piece 21 is less than or equal to the width of the accommodation groove 11. To facilitate the mounting and cooperation of the locking piece 21 and the elastic piece 3, optionally, the accommodation groove 11 and the first boss 12 are both disposed on the bottom surface of the base 1. To reduce the overall weight of the hardware mounting structure, optionally, the base 1 is provided with a through hole 14 configured to reduce the weight of the base 1.
To achieve the rotational connection between the rotation part 2 and the base 1, optionally, the base 1 is provided with a first connection hole 13, the rotation part 2 further includes a connection shaft 22 fitting with the first connection hole 13, and the locking piece 21 is disposed on one end of the connection shaft 22. To facilitate the rotation of the connection shaft 22 through a mounting tool, optionally, a second connection hole 221 is disposed in the connection shaft 22. Optionally, a cross section of the second connection hole 221 is a regular hexagon, which is convenient for use with the existing mounting tool. Optionally, a second boss 211 is disposed on one side of the locking piece 21 facing away from the connection shaft 22, and a side surface of the second boss 211 is used for abutting against the elastic piece 3. In this embodiment, the second boss 211 may be integrally formed with the connection shaft 22, and the locking piece 21 is sleeved on the connection shaft 22.
As shown in FIG. 2, in this embodiment, the first connection hole 13 is disposed on a bottom of the accommodation groove 11.
As shown in FIGS. 2 and 5, in this embodiment, the locking piece 21 has two opposite sides that do not protrude out of an outer edge of the second boss 211 when the locking piece 21 is in the protruding state and also has two opposite ends protrude out of the outer edge of the second boss 211 when the locking piece 21 is in the protruding state. In some examples, the orientation of the two opposite sides of the locking piece 21 is substantially perpendicular to the orientation of the two opposite ends of the locking piece 21.
To facilitate the mounting of the elastic piece 3, optionally, the elastic piece 3 is installed on the first boss 12 through a connection plate 31. To facilitate the mounting of the connection plate 31, optionally, the first boss 12 is provided with a clamping protrusion 121, and the connection plate 31 is provided with a third connection hole 311 fitting with the clamping protrusion 121. The structure is stable and easy to disassemble and assemble.
In the hardware mounting structure provided in this embodiment, during mounting, the following steps are included: the hardware mounting structure is placed vertically in the groove of the profile 100. The rotation part 2 is rotated on the base 1 through the mounting tool inserted into the second connection hole 221 of the connection shaft 22, the rotation part 2 drives the locking piece 21 to rotate together, and the two ends of the locking piece 21 protrude out of the accommodation groove 11 to be engaged with the groove of the profile 100. The one end of the elastic piece 3 is pressed upon the locking piece 21, where the elastic piece 3 is installed on the first boss 12. During the rotation of the locking piece 21, under the elastic force of the elastic piece 3, the one end of the elastic piece 3 gradually switches to abut against the side surface of the locking piece 21, so as to limit the rotation of the locking piece 21. This structure has a self-locking function.
It is to be understood that the hardware mounting structure may be configured to install a component in the groove of the profile 100. For example, the base 1 may be fixed on a component, and the locking piece 21 is disposed on one side of the hardware mounting structure facing away from the component. The bottom surface of the base 1 faces to the groove of the profile 100, and the locking piece 21 protrudes into the groove of the profile 100. Through the rotation of the locking piece 21, the hardware mounting structure is clamped in the groove of the profile 100. In this manner, the connection between the assembly and the profile 100 is achieved.
The hardware mounting structure provided in this embodiment is convenient to operate, simple in structure, high in mounting efficiency, stable in structure, and has a self-locking function.
