Detailed Implementation

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] 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 herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1-11 Figures show the structure of the side-pressing device of this utility model and its components. As shown in the figures, this utility model provides a side-pressing device, the overall structure of which includes a fixed mounting base 6, a sliding base 9, and a driving assembly. The fixed mounting base 6 is mounted on the surface of the sliding base 9, and a transmission rod assembly 1 is provided on the surface of the fixed mounting base 6. An S-groove 91 is provided on the sliding base 9. The driving assembly includes a driving collar 4 and a driving rivet 5. The bottom end of the driving rivet 5 passes through the sliding base 9, and the top end passes through the driving collar 4 and is riveted to the transmission rod assembly 1. A roller 13 is installed at the bottom end of the sliding base 9. A clearance 912 is provided between the curved part of the S-groove 91 and the driving collar 4.

[0030] In many side-pressure door and window products, jamming occurs during operation, requiring increased operating force at certain points, due to obstruction during sliding within the S-groove. The side-pressure device of this invention features a clearance 912 between the curved portion of the S-groove and the drive collar.

[0031] like Figure 4 As shown, the curved part of the S-groove of this utility model is provided with a clearance 912. When the drive collar slides to the highest sliding position 911, due to the existence of the clearance, a clearance angle α is formed, so that the drive collar has a clearance during the sliding process under force at the highest position and does not affect the sliding of the drive collar, thus ensuring smooth sliding of the drive collar.

[0032] Furthermore, in one possible implementation, the S-groove is designed with an inclination to ensure that the drive collar has a certain inclination space within the S-groove, for example, see [reference needed]. Figure 5 As shown, the S-groove is designed with an inclination angle b, which causes the drive collar to tilt during the sliding process when it is under force at the highest point, reducing friction and jamming caused by the tilt. This tilt design can ensure smooth sliding of the drive collar.

[0033] In one possible implementation, the side-pressing device further includes a baffle plate with a rivet hole. The fixed mounting base has grooves at both ends corresponding to the baffle plate. The sliding base has a rivet head with the rivet hole fitted onto the rivet head. The mounting screw passes through the rivet head to rivet the baffle plate into the groove.

[0034] In one possible implementation, the sliding seat 9 is provided with a guide surface 93, the guide surface 93 is provided with a guide groove 931, and the bottom end of the fixed mounting seat 6 is provided with a guide boss 62 that matches the guide groove 931.

[0035] Please combine Figure 6 and Figure 7 As shown, by employing a baffle riveting structure, the fixed mounting base is placed on the sliding base, and then the baffle 7 is inserted into the groove 61 of the fixed mounting base 6. The riveting hole 71 of the baffle 7 fits onto the riveting head 92 of the sliding base 9, and then all the riveting heads 92 of the sliding base 9 are riveted. After riveting, the fixed mounting base 6 is sandwiched between the baffle 7 and the sliding base 9, making the three parts a single unit. The guide surface 93 and guide groove 931 on the sliding base 9 cooperate with the guide boss 62 of the fixed mounting base 6 for guidance, realizing longitudinal sliding. Since the baffle 7 is riveted into the groove of the fixed mounting base 6, the sliding base 9 will not fall off when the fixed mounting base and the sliding base slide longitudinally.

[0036] In one possible implementation, the side pressure device further includes a mounting plate 16, which is respectively disposed on the front and rear sides of the sliding seat 9 and riveted to the sliding seat 9 by a central nail shaft 11.

[0037] Many door and window tracks suffer from deformation and bending. To address this issue, the side-pressing device of this invention rivets the mounting plate 16 to the sliding seat 9 with a central nail shaft 11. The nail shaft 11 provides single-point support and serves as a rotation fulcrum, thus the mounting plate 16 exhibits a seesaw structure. This structure effectively addresses deformed and bent tracks, ensuring that the rollers 13 on both sides remain on the track, while the fixed mounting seat 6 and transmission rod assembly 1 remain horizontal. This results in stable and non-tilting doors and windows with smooth sliding.

[0038] In one possible implementation, the rollers 13 are riveted to both ends of the mounting plate 16 via the pin shafts 11.

[0039] In one possible implementation, the side pressure device further includes an initial positioning pin 10, which passes through the sliding seat 9 and the fixed mounting seat 6 and is riveted to the drive rivet 5.

[0040] The initial installation positioning pin 10 passes through the hole in the fixed mounting base 6 and is inserted into the drive rivet 5 riveted to the transmission rod assembly 1. This design is for initial installation positioning because if door and window installers do not have an installation positioning reference or install it incorrectly, the movement will be uneven and incomplete, seriously affecting the comfort of operation and also affecting the airtightness of the doors and windows. Therefore, the initial installation positioning pin 10 allows workers to have an installation reference during installation, ensuring consistent positioning and improving the quality of the entire system.

[0041] In one possible implementation, a guide wheel 15 is also rotatably mounted on the bottom end of the sliding seat 9.

[0042] In one possible implementation, the fixed mounting base 6 is provided with guide components at both ends. The guide components include guide rivets 2 and guide collars 3. The guide rivets 2 pass through the guide collars 3 and are riveted into the slide grooves 110 of the transmission rod assembly 1.

[0043] In this utility model, the driving rivet 5 passes through the driving collar 4 and is riveted to the transmission rod assembly 1, and the guide rivet 2 passes through the guide collar 3 and is riveted to the fixed mounting base 6. During operation, as... Figure 10 As shown in the figure, the transmission rod assembly 1 and the fixed mounting base 6 are as follows. When the transmission rod assembly 1 moves laterally, the guide collar 3 rolls in the slide groove 110 of the transmission rod assembly 1, and the rolling friction reduces resistance. The drive collar 4 rolls in the S slide groove of the fixed mounting base 6, which also reduces resistance through rolling friction. The rolling friction of both reduces resistance and improves the smoothness of lateral pressure.

[0044] In one possible implementation, the upper surface of the fixed mounting base 6 is also provided with a positioning protrusion 63, which cooperates with the profile 17 to achieve centered positioning during installation.

[0045] The positioning protrusions 63 on the fixed mounting base 6 serve a centering and positioning function during installation. All positioning protrusions 63 are blocked by the profile to prevent misalignment, ensuring the device is centered within the profile groove. Without these positioning protrusions, workers would be unsure of the installation position, leading to deviations or angled installations. If both sets of devices are not installed correctly, they cannot move synchronously with lateral pressure, potentially causing doors and windows to not close tightly, severely impacting operational comfort and affecting the airtightness of doors and windows.

[0046] In one possible implementation, bearing sleeves 12 are provided on both sides of the roller 13.

[0047] The above detailed description of the side-pressure device, in conjunction with the accompanying drawings, indicates that the side-pressure device includes a fixed mounting base, a sliding base, and a drive assembly. The fixed mounting base is mounted on the surface of the sliding base, and a transmission rod assembly is provided on the surface of the fixed mounting base. The sliding base has an S-groove. The drive assembly includes a drive collar and a drive rivet. The bottom end of the drive rivet passes through the sliding base, and the top end passes through the drive collar and is riveted to the transmission assembly. A roller is mounted on the bottom end of the sliding base. A clearance is provided between the curved part of the S-groove and the drive collar. Through this structural design, the drive collar tilts along with the S-groove during sliding under force at its highest point, avoiding obstruction of sliding within the S-groove, reducing friction and jamming caused by tilting, and ensuring smooth sliding.

[0048] Furthermore, a baffle riveting structure is adopted. After riveting, the fixed mounting base is clamped between the baffle and the sliding base, so the sliding base will not fall off when the fixed mounting base and the sliding base slide longitudinally.

[0049] The positioning design, including the initial positioning pin and the positioning protrusion, ensures that the device is centered and will not deviate during installation, thus ensuring that the device is installed centered in the profile groove.

[0050] When the transmission rod assembly moves laterally, the guide collar rolls within the groove of the transmission rod assembly, and the rolling friction reduces resistance. The drive collar also rolls within the S-groove of the fixed mounting base, which also reduces resistance through rolling friction. This combined rolling friction reduces resistance and improves the smoothness of lateral pressure flow.

[0051] The mounting plate is riveted to the sliding seat by a nail shaft. The nail shaft is a single-point support and also serves as a rotation fulcrum, so the mounting plate has a seesaw structure to cope with the deformation and bending of the track, ensuring that the rollers 13 on both sides are always on the track, while the fixed mounting seat and transmission rod assembly can remain horizontal, thus making the door and window stable and not tilted, and the sliding smooth.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
