[0001] This utility model belongs to the field of door and window technology, specifically relating to an anti-sway side-pressure upper pulley and window. Background Technology

[0002] Side-push sliding doors and windows, also known as drifting doors and windows, can slide the door / window sash outside the frame by switching the hardware system, thus enabling the door / window sash to slide. In existing technology, after the door / window sash slides away from the frame, significant swaying occurs due to gaps between the pulleys and the guide grooves of the frame, or gaps within the pulley system itself. The traditional solution is to add anti-sway blocks between the frame and the sash. While this method reduces swaying to some extent, it requires a high degree of compatibility between the sash and frame, has poor versatility, and the installation is cumbersome.

[0045] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0047] See Figures 1-10 This embodiment discloses an anti-sway side-pressure upper pulley, including a base 1, a drive bar 3, a swing member 2, and a guide wheel 4. The base 1 is fixed in the fan frame 12, the drive bar 3 is slidably mounted on the base 1 and moves with the transmission components of the hardware system, and the swing member 2 is rotatably mounted on the base 1; when the drive bar 3 slides, it drives the swing member 2 to rotate, and the rotation of the swing member 2 causes the guide wheel 4 to translate relative to the base 1, so as to realize that the fan frame 12 translates out of or into the frame 11.

[0048] In this embodiment, the seat 1 is provided with an elastic buffer 6. When the guide wheel 4 and the seat 1 move relative to each other so that the sash frame 12 is in a state away from the frame 11, the swing member 2 and the elastic buffer 6 abut against each other, which can effectively eliminate the gap in the upper pulley's own structure, thereby helping to reduce the amount of shaking when the door and window sash is open and improve the stability of the door and window sash's push-pull sliding.

[0049] In this embodiment, the middle part of the swing member 2 is rotatably connected to the seat 1; the drive bar 3 drives the swing member 2 to swing while sliding through the drive structure; the drive structure includes a drive groove 301 and a drive member 8, the drive member 8 is embedded in the drive groove 301, and the extension direction of the drive groove 301 is inclined to the moving direction of the drive bar 3 so that the drive bar 3 drives the swing member 2 to rotate when sliding.

[0050] In this embodiment, the drive groove 301 can be disposed on the drive bar 3, in which case the drive component 8 is disposed at the first end of the swing component 2. Alternatively, the drive groove 301 can be disposed at the first end of the swing component 2, while the drive component 8 is disposed on the drive bar 3. In this embodiment, the drive component 8 adopts a pin structure and is riveted to the swing component 2, while the drive groove 301 is correspondingly disposed on the drive bar 3. Of course, the structure of the drive component 8 can also be selected in other ways. In this embodiment, through the above-described drive structure, the drive bar 3 slides and moves while the swing component 2 rotates through the cooperation of the drive component 8 and the drive groove 301, forming a lever drive effect, which makes the drive bar 3 feel better and smoother, and less strenuous. In this embodiment, the drive bar 3 is connected to the transmission components of the door and window hardware system. For example, the sliding action of the drive bar 3 can be controlled by rotating the handle, and the specific details can also be found in the prior art.

[0051] In this embodiment, the guide wheel 4 can be connected to the second end of the swing member 2 and move directly with the rotation of the swing member 2. When the swing member 2 rotates, the second end of the swing member 2 drives the guide wheel 4 to translate relative to the base 1. In this embodiment, the guide wheel 4 is directly connected to the second end of the swing member 2, and the guide wheel 4 can be rotatably connected to the swing member 2 through bearings, pins, or other means.

[0052] In another embodiment, the guide wheel 4 can also be slidably mounted on the base 1, and the base 1 is provided with a matching groove. When the swing member 2 rotates, it makes the guide wheel 4 move in the groove by flicking.

[0053] Furthermore, the second end of the swing member 2 is provided with a protruding bump 202, and the elastic buffer member 6 is located at the corresponding position of the bump 202; when the guide wheel 4 and the seat 1 move relative to each other so that the fan frame 12 is in a state away from the frame 11, the bump 202 and the elastic buffer member 6 abut against each other.

[0054] Furthermore, in this embodiment, the protrusion 202 and the side of the swing member 2 form a corner, and one side of the elastic buffer member 6 corresponds to the side of the protrusion 202, so that when the protrusion 202 and the elastic buffer member 6 are pressed together, their sides can have a certain area of ​​contact, thereby forming a better gap elimination effect and achieving the purpose of anti-swaying. The elastic buffer member 6 in this embodiment can be selected as buffer rubber or other parts made of a certain elastic material.

[0055] Of course, the mutual abutment position of the elastic buffer 6 and the swing member 2 in this embodiment can be flexible and varied, and is not limited to the example in this embodiment. For example, the elastic buffer 6 can also be set at a position close to the first end of the swing member 2, or at a position in the middle of the swing member 2, as long as the elastic buffer 6 can abut against the swing member 2 when the door or window is open.

[0056] In this embodiment, the seat 1 is provided with a stop 1024, and an elastic buffer 6 is disposed on one side of the stop 1024. The side of the elastic buffer 6 facing away from the stop 1024 is used to abut against the swing member 2. In this way, the stop 1024 can effectively maintain the position of the elastic buffer 6, thereby preventing the elastic buffer 6 from being displaced by the force of the swing member 2, and thus improving the anti-sway effect.

[0057] See Figures 7-8 At this time, the doors and windows are locked. When the drive bar moves to the 3rd position... Figure 8 When the door / window sash moves to the left, the drive groove 301 and the drive component 8 work together to rotate the swing component 2 clockwise. The guide wheel 4 moves synchronously with the swing component 2, causing the guide wheel 4 to translate relative to the seat 1, thus allowing the sash frame 12 to slide out from the frame 11. At this time, the protrusion 202 on the swing component 2 and the elastic buffer 6 abut against each other, eliminating their own gaps and helping to prevent the door / window sash from shaking when sliding. Figure 9 and Figure 10 As shown.

[0058] Furthermore, the swing member 2 is provided with a first positioning hole 201, and the base 1 is provided with a second positioning hole 1022. When the first positioning hole 201 and the second positioning hole 1022 are aligned, the swing member 2 and the elastic buffer member 6 abut against each other. In this way, the swing member 2 can be quickly adjusted to the initial position by referring to the first positioning hole 201 and the second positioning hole 1022. The positioning block 5 can be inserted into the first positioning hole 201 and the second positioning hole 1022 to fix the initial position of the swing member 2. This initial position can be used as the factory configuration of the anti-sway side-pressure upper pulley in this embodiment, or it can be used during installation to ensure that the swing member 2 and the elastic buffer member 6 have a mutual abutting effect after the fan frame 12 leaves the frame 11 during use, thereby achieving the effect of eliminating the gap of the upper pulley itself. In this embodiment, a third positioning hole 302 is provided on the drive bar 3. The third positioning hole 302 corresponds to the first positioning hole 201 and the second positioning hole 1022. In this way, the positioning block 5 can be inserted into the three positioning holes to fix the factory state of the product.

[0059] The base 1 in this embodiment includes a base plate 101 and a support plate 102. A sliding groove is formed between the base plate 101 and the support plate 102, and the drive bar 3 is located in the sliding groove. The swing member 2 is rotatably connected to the support plate 102. Further, the support plate 102 in this embodiment is provided with a clearance groove 1021 for avoiding the drive member 8. The clearance groove 1021 corresponds to the rotation trajectory of the drive member 8 with the swing member 2. The drive member 8 is riveted to the swing member 2 and, after passing through the clearance groove 1021, is embedded in the drive groove 301 on the drive bar 3.

[0060] Furthermore, the support plate 102 is provided with a rotating pin 7, which can be riveted to the support plate 102. The swing member 2 has a hole in the middle that cooperates with the rotating pin 7, so that the swing member 2 can be rotated.

[0061] A connector 9 is attached to the drive bar 3, extending along one side of the guide wheel 4. The connector 9 is used to connect with the transmission component of the hardware system. In this embodiment, two connectors 9 are provided, located at both ends of the drive bar 3, and can be connected to the drive bar 3 by riveting. Of course, the number and position of the connectors 9 can be flexibly adjusted. The transmission component in the hardware system can be a transmission plate or other components, which can form a power transmission with the handle, enabling the handle to control the sliding action of the drive bar 3.

[0062] Reinforcing plates 10 are provided at both ends of the support plate 102 and the base plate 101 to improve the reliability between the support plate 102 and the base plate 101. In addition, the support plate 102 and the base plate 101 in this embodiment can be formed into a whole by fastening, pressing or other component combinations.

[0063] The drive bar 3 is provided with a first limiting part 303, and the sliding groove is provided with a second limiting part 1023. The first limiting part 303 and the second limiting part 1023 interact to limit the sliding distance of the drive bar 3. Further, in this embodiment, the first limiting part 303 can be a first step, and in this embodiment, there are two first steps on the drive bar 3; while the second limiting part 1023 can be a second step on the support bar, and there are also two second steps, as shown in the figure. In this way, the sliding distance of the drive bar 3 is limited by the interaction of the first step and the second step. In addition to the method of this embodiment, other methods can also be used to limit the sliding distance of the drive bar 3, such as a boss structure.

[0064] This embodiment also discloses a window, including a sash frame 12, a frame 11, and anti-sway side-pressing pulleys. The base can be fixedly installed on the sash frame 12, while the guide wheel 4 cooperates with the guide groove 1101 on the frame 11.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
