[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0040] Refer to Figures 1 - 7 , the present utility model discloses a slide groove and pull rod assembly that can achieve universal left and right assembly, including: a mounting plate 10; a slide groove and pull rod structure 20, the slide groove and pull rod structure 20 includes a slide sleeve 201 and a pull rod 202, the slide sleeve 201 is slidably connected to the pull rod 202, and one end of the slide sleeve 201 is rotatably connected to the mounting plate 10; a limiting member 30, the limiting member 30 is arranged on one side of the slide sleeve 201 to limit the rotation of the slide sleeve 201 towards the side of the limiting member 30; an elastic element 40, the elastic element 40 is arranged at the rotational connection position between the slide sleeve 201 and the mounting plate 10, and one end of the elastic element 40 abuts against the slide sleeve 201, and the other end of the elastic element 40 abuts against the mounting plate 10, so that the slide sleeve 201 stops at different rotational positions.

[0041] It should be noted that the sliding sleeve 201 and the pull rod 202 are coaxially arranged. A linear groove for cooperating with the pull rod 202 is provided on the sliding sleeve 201, so that the pull rod 202 slides along the sliding sleeve 201.

[0042] In the chute pull rod assembly of the present utility model that can achieve universal left and right assembly, a limiting member 30 is provided to limit the rotation direction and position of the sliding sleeve 201. The limiting member 30 can be installed on the left or right side of the sliding sleeve 201, and can be applicable to the leftward assembly or rightward assembly use scenarios; and by providing an elastic element 40, the sliding sleeve 201 can be stagnated at different rotation positions, which is convenient for operation and improves the user's comfort.

[0043] It should be noted that due to the provision of the limiting member 30, the sliding sleeve 201 can only rotate towards the side without the limiting member 30, and when the sliding sleeve 201 is reset, it can abut against the limiting member 30 to prevent the sliding sleeve 201 from shifting during reset; the elastic element 40 plays a role in tightening the sliding sleeve 201 and the mounting plate 10, so that the sliding sleeve 201 can be stagnated at the rotation angle.

[0044] In the embodiment of the present utility model, the elastic element 40 is a wave washer.

[0045] Specifically, the sliding sleeve 201 and the mounting plate 10 are rotationally connected through a rotating shaft, and the elastic element 40 is sleeved outside the rotating shaft.

[0046] In the embodiment of the present utility model, the sliding sleeve 201 and the pull rod 202 are nested. The sliding sleeve 201 is sleeved outside the pull rod 202, or the pull rod 202 is sleeved outside the sliding sleeve 201.

[0047] In this way, the specific relative position of the sliding sleeve 201 and the pull rod 202 only needs to be able to achieve the sliding of the pull rod 202 relative to the sliding sleeve 201.

[0048] In the embodiment of the present utility model, a first limiting convex portion 203 is provided at the other end of the sliding sleeve 201, a locking point 204 is provided at one end of the pull rod 202, a first limiting concave portion 205 for cooperating with the first limiting convex portion 203 is provided at the other end of the pull rod 202, and an avoidance groove 206 for avoiding the first limiting convex portion 203 is provided in the middle of the pull rod 202.

[0049] Specifically, the first limiting convex portion 203 is arc-shaped. When the pulling force of the user pulling the pull rod 202 reaches a predetermined value, the first limiting convex portion 203 can be snapped into the first limiting concave portion 205, or the first limiting convex portion 203 can be disengaged from the first limiting concave portion 205. The cooperation between the first limiting convex portion 203 and the first limiting concave portion 205 is a temporary cooperation. In this way, through the cooperation between the first limiting convex portion 203 and the first limiting concave portion 205, the pull rod 202 is prevented from disengaging from the sliding sleeve 201, and the maximum stroke of the pull rod 202 is limited.

[0050] In the embodiment of the present invention, the chute pull rod assembly capable of realizing universal left and right assembly further includes a first connecting member 50. The limiting member 30 is rotatably connected to the mounting plate 10 through the first connecting member 50. A second limiting convex portion 301 is provided on the limiting member, and the mounting plate is provided with a second limiting concave portion 102 for cooperating with the second limiting convex portion 301.

[0051] During use, according to the actual application scenario, the limiting member 30 is rotated to the left or right side of the mounting plate 10 around the first connecting member 50. The first connecting member 50 can adopt a rotating shaft to facilitate the rotation of the limiting member 30. After rotating in place, the limiting member 30 is clamped and fixed by the cooperation between the second limiting convex portion 301 and the second limiting concave portion 102. The second limiting convex portion 301 is an arc-shaped convex point, and when the rotating force reaches a predetermined value, the second limiting convex portion 301 can be disengaged from the second limiting concave portion 102.

[0052] In order to prevent the chute pull rod structure 20 from affecting the rotation of the limiting member 30 for adjusting the position, the position adjustment of the limiting member 30 needs to be completed before the chute pull rod assembly capable of realizing universal left and right assembly is installed into the door and window system. During adjustment, the chute pull rod structure 20 is rotated to another position. After the limiting member 30 is clamped and fixed, the chute pull rod structure 20 is reset from another direction. Of course, the chute pull rod structure 20 can also be disassembled. After the limiting member 30 is rotated, the chute pull rod structure 20 is installed again.

[0053] In the embodiment of the present invention, the limiting member 30 is provided at one end of the mounting plate 10, and the middle part of the mounting plate 10 is rotatably connected to the sliding sleeve 201.

[0054] In the embodiment of the present invention, the end of the mounting plate 10 is provided with an avoidance concave portion 101 for installing the limiting member 30. The limiting member 30 is generally in a "U" shape. The limiting member 30 has a first bent portion 302 and a second bent portion 303. The first bent portion 302 is used for cooperating with the sliding sleeve 201, and the second bent portion 303 is used for cooperating with the avoidance concave portion 101.

[0055] In this way, the limiting member 30 fills the space of the avoidance concave portion 101 through its second bent portion 303, and the limiting member 30 plays a supporting role for the sliding sleeve 201.

[0056] In an embodiment of the present utility model, the chute pull rod assembly capable of realizing universal left and right assembly further includes a second connecting member 60 and a clamping piece 70. The second connecting member 60 and the clamping piece 70 are arranged at the other end of the mounting plate 10, and the mounting plate 10 is fixedly connected to the window frame through the second connecting member 60 and the clamping piece 70.

[0057] Specifically, the second connecting member 60 can adopt a screw, which is convenient for the installation of the mounting plate 10.

[0058] In an embodiment of the present utility model, the chute pull rod assembly capable of realizing universal left and right assembly further includes a sliding sleeve cover 207. The sliding sleeve cover 207 is arranged at one end of the sliding sleeve 201, and the other end of the sliding sleeve 201 is an opening through which the pull rod 202 slides in and out relatively; the sliding sleeve cover 207 can prevent the pull rod 202 from disengaging from the sliding sleeve 201.

[0059] Refer to Figure 8 , the present utility model discloses a door and window system, including the chute pull rod assembly capable of realizing universal left and right assembly according to any one of the above.

[0060] The door and window system in the present utility model adopts a chute pull rod assembly capable of realizing universal left and right assembly, and can be applicable to leftward assembly or rightward assembly usage scenarios.

[0061] The door and window system further includes a handle 80, a transmission 90, a window frame 100 and a window sash 110. The handle 80 and the transmission 90 are installed on the window sash 110. The transmission 90 includes a transmission bar and a jacking element that cooperate with each other. The jacking element can adopt a cam or a gear. The handle 80 is integrally connected to the jacking element, and the handle and the jacking element rotate together, thereby driving the transmission bar to move up and down. A clamping groove for cooperating with the lock point 204 is arranged on the transmission bar.

[0062] When the jacking element is a cam, the jacking element abuts against the transmission bar, and the transmission bar is arranged above the jacking element; when the jacking element is a gear, meshing teeth meshing with the jacking element are arranged on the transmission bar; it should be noted that how to realize the movement of the transmission 90 by rotating the handle 80 can be achieved by the prior art and will not be elaborated here.

[0063] When the handle 80 rotates by a first predetermined angle, for example, when the handle 80 rotates by 90 degrees, the card slot on the transmission bar and the locking point 204 are still in a mating state, and the window sash 110 can be pushed out. During the process of pushing out the window sash 110, the entire chute pull rod structure 20 rotates relative to the mounting plate 10, and the pull rod 202 slides out relative to the sliding sleeve 201. However, at the same time, limited by the movement stroke of the pull rod 202, the window sash 20 can only be partially opened, thereby realizing micro-ventilation. When the handle 80 rotates by a second predetermined angle, for example, when the handle rotates by 180 degrees, the card slot on the transmission bar is disengaged from the locking point 204, and the window sash 110 can be fully opened, being in a normal opening state.

[0064] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
