Patent Description:
In the existing door or window structure, a frame body profile and a leaf body profile are both provided with a groove structure in which a hardware transmission assembly is mounted so that a transmission structure of the frame body and the leaf body is formed and thus the leaf body and the frame body can be opened or locked. The hardware transmission assembly includes transmission rods, conversion transmission parts, and multiple hardware parts.

However, the existing door and window hardware and transmission rods (aluminum rods and plastic rods) all adopt a traditional slotting mounting method. During mounting, the length of the transmission rod needs to be accurately calculated and punching needs to be performed at a preset position. The existing door and window hardware and transmission rods have complex structures, cumbersome operation, long mounting time, and low mounting efficiency.

<CIT> discloses a device <NUM> for fixing a fitting <NUM> in a T-shaped groove <NUM> of a fixed or opening frame type joinery, T-shaped groove <NUM> delimited by at least one bottom <NUM> and two side walls <NUM>, <NUM> each provided with at least one hooking rim <NUM>, <NUM> distant from the bottom <NUM>.

<CIT> discloses the sliding blocks (<NUM>,<NUM>) have ends with different curved front side contact surfaces (<NUM>,<NUM>,<NUM>,<NUM>) for installing at a groove wall. The sliding block are formed relative to a central longitudinal plane and a fulcrum (<NUM>,<NUM>) is formed asymmetrically. The contact surfaces are arranged away from the fulcrum of the sliding block.

<CIT> discloses the push-rod fitting in a door frame or window frame is mounted in a recess and covered by a flat metal strip. This is secured by rotatable toggles which protrude beyond the width of the opening in which the push-rod is mounted. Eccentric discs (<NUM>) are tightly threaded on screws (<NUM>) which pass through the cover strip, the surface of their countersunk heads coinciding with the outer cover surface. Initial screw rotation brings the disc (<NUM>) into contact with the recess walls, after which further screw tightening presses the disc into tight contact with the shoulders (<NUM>). The screws pass through slots in the push-rod (<NUM>).

The present application provides a mounting structure according to independent claim <NUM>, which has a simple structure and is convenient for mounting.

The present application adopts technical solutions described below.

Provided is a mounting structure, including a transmission part, a transmission rod, and a profile, where the transmission rod is disposed in a groove of the profile, and the transmission part is provided with a clamping assembly and mounted in the groove of the profile through the clamping assembly.

The clamping assembly includes a base, a rotation part, and an elastic piece.

The base is provided with an accommodation groove and a first boss.

The rotation part is disposed in the accommodation groove and rotatably connected to the base, where the rotation part includes a locking piece, and two ends of the locking piece are capable of protruding out of the accommodation groove to be engaged with the groove of the profile when the rotation part rotates.

A first end of the elastic piece along a length direction of the elastic piece is mounted on the first boss.

In a case that the two ends of the locking piece do not protrude out of the accommodation groove, a second end of the elastic piece along the length direction of the elastic piece is pressed upon the locking piece. And in a case that the two ends of the locking piece protrude out of the accommodation groove during rotation of the locking piece and the second end of the elastic piece is abutting against a side surface of the locking piece, the rotation of the locking piece is limited.

This embodiment provides a mounting structure used for mounting a leaf body of a door or window. As shown in <FIG>, the mounting structure includes a transmission part, a transmission rod, and a profile <NUM>, where the transmission part is a conversion rod <NUM>, a lock rod, or an angle actuator, and the transmission rod is disposed in a groove of the profile <NUM>. To facilitate understanding, in this embodiment, the case where a conversion rod <NUM> is the transmission part is used as an example for description. The conversion rod <NUM> is configured to convert a rotational force from a user into a force required to unlock the leaf body from a frame body. The conversion rod <NUM> is provided with a clamping assembly <NUM> and mounted in the groove of the profile <NUM> through the clamping assembly <NUM>. In this embodiment, the profile <NUM> forms a leaf body frame of the door or window, and two ends of the conversion rod <NUM> are both provided with a clamping assembly <NUM>. The clamping assembly <NUM> includes a base <NUM>, a rotation part <NUM>, and an elastic piece <NUM>. The base <NUM> is part of the conversion rod <NUM>, and for ease of description of the clamping assembly <NUM>, the base <NUM> is named separately for description.

In some examples, the transmission rod can slide in the groove of the profile <NUM> along a length direction of the transmission rod. The transmission part (such as the conversion rod <NUM>, the lock rod, or the angle actuator) is connected to the transmission rod and configured to allow the transmission rod to slide in the groove of the profile <NUM> along the length direction of the transmission rod.

In some examples, the transmission part is mounted in the groove of the profile <NUM> through the clamping assembly <NUM> to slidably limit the transmission rod in the groove of the profile <NUM>.

In some examples, as shown in <FIG>, the base <NUM> is provided with an accommodation groove <NUM> and a first boss <NUM>. The rotation part <NUM> is disposed in the accommodation groove <NUM> and rotatably connected to the base <NUM>, the rotation part <NUM> includes a locking piece <NUM>, and two ends of the locking piece <NUM> can protrude out of the accommodation groove <NUM> to be engaged with the groove of the profile <NUM> when the rotation part <NUM> rotates. A first end of the elastic piece <NUM> along a length direction of the elastic piece <NUM> is mounted on the first boss <NUM>, and a second end of the elastic piece <NUM> along the length direction of the elastic piece <NUM> can abut against a side surface of the locking piece <NUM>, so as to limit rotation of the locking piece <NUM>.

In some examples, the elastic piece <NUM> is configured to limit the rotation of the locking piece <NUM> when the two ends of the locking piece <NUM> protrude out of the accommodation groove <NUM>.

In some examples, the locking piece <NUM> has an initial state and a protruding state. When the locking piece <NUM> is in the initial state, the locking piece <NUM> is completely disposed in the accommodation groove <NUM> and does not protrude out of the accommodation groove <NUM>. When the locking piece <NUM> is in the protruding state, the two ends of the locking piece <NUM> protrude out of the accommodation groove <NUM>.

As shown in <FIG>, in this embodiment, the first boss <NUM> protrudes from a bottom surface of the base <NUM>, and the bottom surface of the base <NUM> and one side surface of the first boss <NUM> define the accommodation groove <NUM> and are inner walls of the accommodation groove <NUM>.

It is to be understood that the two ends of the locking piece <NUM> capable of protruding out of the accommodation groove <NUM> means that the two ends of the locking piece <NUM> can protrude outward relative to circumferential side surfaces adjacent to the bottom surface of the base <NUM>.

In some examples, during the mounting, the transmission rod is directly placed in the groove of the profile <NUM>, the conversion rod <NUM> provided with the clamping assembly <NUM> is placed on the transmission rod, and the conversion rod <NUM> is disposed in the groove of the profile <NUM>; the rotation part <NUM> is rotated on the base <NUM> and drives the locking piece <NUM> to rotate together, and the two ends of the locking piece <NUM> protrude out of the accommodation groove <NUM> to be engaged with the groove of the profile <NUM>, so as to complete the mounting. During mounting, slotting and punching operations do not need to be performed for the cooperation between the transmission rod and the profile, as long as the transmission rod is directly placed in the groove of the profile; and a length of the transmission rod does not need to be accurately calculated. An allowable error range is large and it is convenient and quick to perform mounting so that mounting time is saved. Moreover, one end of the elastic piece <NUM> is pressed upon the locking piece <NUM>, where the elastic piece <NUM> is mounted on the first boss <NUM>. During the rotation of the locking piece <NUM>, under an elastic force of the elastic piece <NUM>, the one end of the elastic piece <NUM> gradually switches to abut against the side surface of the locking piece <NUM>, so as to limit the rotation of the locking piece <NUM>. In this manner, this structure has a self-locking function.
