[0002] A sliding window pusher is a sliding window driving device, which has a driving wheel that abuts against the glass of the sliding window and drives the sliding window by abutment friction. The window pusher can drive the sliding window without large-scale modification of the sliding window (such as installing chains, belt tracks, etc.).

However, the existing sliding window pushers are unable to adjust the positive pressure, which limits their application scenarios. Utility Model Content

[0004] Existing sliding window pushers have strict requirements on the positive pressure control between the drive wheel and the glass. Specifically, if the positive pressure value is set too low, it will cause a non-negligible sliding phenomenon between the drive wheel and the glass, which will not only weaken the effective driving force transmission of the window pusher, but also may cause instability and noise problems during the operation of the window. On the contrary, if the positive pressure is set too high, it will undoubtedly increase the driving resistance, affect the overall performance of the equipment, and may cause unnecessary wear and tear on the glass and the structure of the window pusher itself. Unfortunately, most sliding window pusher products on the market fail to achieve flexible adjustment of this key positive pressure parameter, resulting in it often difficult to accurately match the appropriate positive pressure value when facing different application scenarios (such as different window materials, installation environment factors and different application scenarios), which seriously restricts the overall driving performance and user experience of the window pusher.

[0070] A sliding window pusher is a sliding window driving device, which has a driving wheel that abuts against the glass of the sliding window and drives the sliding window by abutment friction. The window pusher can drive the sliding window without large-scale modification of the sliding window (such as installing chains, belt tracks, etc.).

[0071] The existing sliding window pushers are limited by their driving mode and have strict requirements on the positive pressure between the driving wheel and the glass. However, the existing sliding window pushers cannot adjust the positive pressure, which limits their application scenarios. Specifically, if the positive pressure value is set too low, it will cause a non-negligible sliding phenomenon between the driving wheel and the glass, which will not only weaken the effective driving force transmission of the window pusher, but also may cause instability and noise problems during the operation of the window. On the contrary, if the positive pressure is set too high, it will undoubtedly increase the driving resistance, affect the overall performance of the equipment, and may cause unnecessary wear and tear on the glass and the window pusher's own structure. Unfortunately, most sliding window pusher products on the market fail to achieve flexible adjustment of this key positive pressure parameter, resulting in it often difficult to accurately match the appropriate positive pressure value when facing different application scenarios (such as different window materials and installation environment factors). This seriously restricts the overall driving performance and user experience of the window pusher.

[0072] Based on this, the utility model provides a positive pressure adjustment component 110 and a driving device 100 in one embodiment. Based on the adjustment function of the positive pressure adjustment component 110, the driving device 100 provided by the utility model can have the ability to flexibly adjust positive pressure, thereby improving its functional adaptability and adaptability to usage scenarios.

The technical details of the positive pressure adjusting member 110 are described below.

[0074] See also Figure 1-Figure 20 , a positive pressure regulating member 110 provided in an embodiment of the present utility model is shown, wherein Figure 1-Figure 4 is a first embodiment of the positive pressure regulating member 110, Figure 5-Figure 9 The second embodiment of the positive pressure regulating member 110 is shown in FIG. Fig.10 The third embodiment of the positive pressure regulating member 110 is shown in FIG. Figure 11-Figure 14 The fourth embodiment of the positive pressure regulating member 110 is shown in FIG. Figure 15-18 A fifth embodiment of the positive pressure regulating member 110 is shown. Figure 19-20 This is a sixth embodiment of the positive pressure regulating member 110 .

The positive pressure adjusting member 110 provided by the utility model can adjust the positive pressure between the driving wheel 1901 and the driven surface to an appropriate size, so as to avoid the situation where the positive pressure is too small, resulting in slippage between the driving wheel 1901 and the glass, or the positive pressure is too large, resulting in too much driving resistance. The first direction has been Figure 2 Winning bid.

[0076] The adjusting part 2 can be installed externally by adhesive mounting, screw mounting, etc. The connecting part 1 can be connected to the driving device 190 by snap-fitting, screw mounting, etc. In this embodiment, Figure 3 and Figure 1As shown, the connecting portion 1 includes a frame structure 11 , the shape of the frame structure 11 is adapted to the driving device 190 , the driving device 190 is embedded in the frame structure 11 , and the upper and lower ends of the driving device 190 are respectively clamped to the frame structure 11 .

Figure 3 As shown, before installation, the user needs to drill a connecting hole on the window frame at the position corresponding to the first strip, and the first screw 211 passes through the first strip hole 21 and is connected to the connecting hole. When the first screw 211 is loosely connected to the connecting hole, the first strip hole 21 can slide based on the first screw 211, and then the connecting part 1 can drive the driving device 190 to change its position in the first direction to adjust the positive pressure between the driving wheel 1901 and the driven surface; when the positive pressure between the driving wheel 1901 and the driven surface is adjusted to an appropriate size, the first screw 211 is tightened to the connecting hole, so that the position of the connecting part 1 is locked by the first screw 211, so that the positive pressure will remain at the current size.

[0079] It is worth noting that the first strip-shaped holes 21 can be straight strip-shaped holes, curved strip-shaped holes, rectangular holes, track-shaped circular holes, etc. In a preferred embodiment, the first strip-shaped holes 21 are configured as track-shaped circular holes.

The second side wall 112 is respectively provided with a first operating hole 113 at a position directly opposite to each of the first strip holes 21, and an operating tool can pass through the first operating hole 113 to operate the first screw 211. The first operating hole 113 is set to be a strip hole that matches the shape of the first strip hole 21, so that when the first screw 211 slides to any position in the first strip hole 21, the user can use the operating tool to pass through the first operating hole 113 to operate the first screw 211.

[0081] Furthermore, if Figure 3 As shown, the inner wall of the frame-shaped structure 11 is provided with a first receiving groove 114 at the location of the first strip-shaped hole 21, and the first receiving groove 114 is used to receive the nut of the first screw 211, so that the nut of the first screw 211 does not interfere with the driving device 190. Furthermore, the first receiving groove 114 is opened to the end surface of the frame-shaped structure 11, so as to facilitate the processing and forming of the first receiving groove 114.

In addition, when the driving device 190 is removed, the sliding window can be fully opened, for example Figure 1 After the driving device 190 is removed, the second window 220 can be fully opened to overlap with the first window 210. At this time, the connecting part 1 protrudes from the window frame. If the connecting part 1 is not removed, the user may bump into the connecting part 1, which poses a safety hazard. The connecting part 1 of the embodiment of the utility model is detachably connected to the mounting plate 22. When the driving device 190 is not in use, the connecting part 1 can be removed from the mounting plate 22 to eliminate the safety hazard.

[0083] In some embodiments, Figure 5-Figure 8As shown, the mounting plate 22 is provided with at least one threaded connection structure 26, the connecting part 1 is provided with a second strip hole 13 at a position corresponding to the threaded connection structure 26, a second screw 131 is inserted into the second strip hole 13, and the second screw 131 is connected to the threaded connection structure 26 to realize the detachable connection between the mounting plate 22 and the connecting part 1; the second screw 131 can be locked on the threaded connection structure 26 to fix the relative position of the mounting plate 22 and the connecting part 1; the second strip hole 13 extends toward the first direction, and the second screw 131 can be loosely connected to the threaded connection structure 26, so that the second strip hole 13 slides based on the second screw 131 or the threaded connection structure 26, thereby adjusting the position of the connecting part 1 in the first direction. Among them, the threaded connection structure 26 can be understood as a structure having threads and capable of being connected with the second screw 131, such as a threaded hole, a nut, a pressure riveting stud, etc. In a specific embodiment, the threaded connection structure 26 is set as a pressure riveting stud 261. The sliding of the second strip hole 13 based on the second screw 131 is specifically that the second screw 131 passes through the second strip hole 13 and is connected to the threaded connection structure 26, the width of the second strip hole 13 is adapted to the width of the second screw 131, and the second screw 131 can slide in the second strip hole 13; the sliding of the second strip hole 13 based on the threaded connection structure 26 is specifically that the threaded connection structure 26 passes through the second strip hole 13 and is connected to the second screw 131, the width of the second strip hole 13 is adapted to the width of the threaded connection structure 26, and the threaded connection structure 26 can slide in the second strip hole 13.

[0084] It is worth noting that the second strip-shaped holes 13 can be straight strip-shaped holes, curved strip-shaped holes, rectangular holes, track circular holes, etc. In a preferred embodiment, the second strip-shaped holes 13 are configured as track circular holes.

[0085] Furthermore, if Figure 7 As shown, the self-riveting stud 261 is embedded in the mounting plate 22; the mounting plate 22 includes a first surface 221, the self-riveting stud 261 is embedded in the mounting plate 22 by the first surface 221, and the self-riveting stud 261 does not protrude from the first surface 221, when the mounting plate 22 is installed externally, the first surface 221 is attached to the external mounting surface, so that the connection between the mounting plate 22 and the external mounting surface is more stable; and because the first surface 221 is attached to the external mounting surface, the first surface 221 can be attached to the window frame with double-sided tape to avoid drilling holes in the window frame.

[0086] Furthermore, if Figure 6 and Figure 7As shown, the self-clinching stud 261 includes a hexagonal block and a connecting column extending outward from the hexagonal block, and the connecting column is provided with a threaded hole for connecting the second screw 131. The first surface 221 of the mounting plate 22 is provided with a limiting groove (not shown in the figure) adapted to the hexagonal block, and a limiting through hole 222 is provided inside the limiting groove. The self-clinching stud 261 is embedded in the mounting plate 22 from the first surface 221, the connecting column passes through the limiting through hole 222, and the hexagonal block is embedded in the limiting groove. The limiting groove can limit the rotation of the self-clinching stud 261.

[0087] Furthermore, if Figure 6 As shown, the mounting plate 22 is provided with two self-clinching studs 261, and the connecting portion 1 is respectively provided with the second strip holes 13 at the positions corresponding to the respective self-clinching studs 261, and each of the second strip holes 13 is connected to the corresponding self-clinching studs 261 through the second screws 131; wherein, the two self-clinching studs 261 are respectively arranged at positions close to the upper and lower ends of the mounting plate 22 to enhance the locking ability of the second screws 131 and prevent the position of the connecting portion 1 from changing; and the provision of the two self-clinching studs 261 can also prevent the driving device 190 from tilting under the action of the positive pressure.

[0088] like Figure 6-Figure 8 As shown, the mounting plate 22 is provided with two mounting holes 223, and the mounting holes 223 are externally mounted by third screws 2231; the connecting portion 1 is provided with a first accommodating space 141 and a second accommodating space 142, the first accommodating space 141 is used to accommodate the third screws 2231, and the second accommodating space 142 is used to accommodate the pressure riveting stud 261, so that the mounting plate 22 is fitted to the connecting portion 1, thereby enhancing the connection stability between the connecting portion 1 and the mounting plate 22. Among them, the second accommodating space 142 is used to accommodate the connecting column of the pressure riveting stud 261, specifically, the connecting column passes through the limiting through hole 222, and the end of the connecting column is placed in the second accommodating space 142, so that the connecting column is longer, so that the locking force between the connecting column and the second screw 131 is greater. The first accommodating space 141 and the second accommodating space 142 are both configured as strip grooves, and the extending direction of the strip grooves is the first direction, so that when the connecting part 1 is adjusted in the first direction, the first accommodating space 141 can always accommodate the third screw 2231, and the second accommodating space 142 can always accommodate the rivet stud 261.

[0089] Furthermore, if Figure 6-Figure 8As shown, spare mounting holes 224 are respectively provided near the upper and lower ends of the mounting plate 22, and the spare mounting holes 224 can be connected to the external mounting surface using a sixth screw (not shown in the figure) to improve the connection stability between the mounting plate 22 and the external mounting surface. The connecting portion 1 is provided with a third accommodating space 143 toward the mounting plate 22, and the third accommodating space 143 is used to accommodate the nut of the sixth screw so that the mounting plate 22 fits the connecting portion 1. Furthermore, prying openings 15 are respectively provided at the upper and lower ends of the connecting portion 1, and the prying openings 15 are provided on the side of the connecting portion 1 facing the mounting plate 22, and the prying openings 15 are used to insert a screwdriver to separate the connecting portion 1 from the mounting plate 22.

[0090] In some embodiments, Figure 6-Figure 8 As shown, the connecting portion 1 includes a frame structure 11, which is used to be sleeved on the driving device 190; the frame structure 11 includes a first side wall 111 close to the mounting plate 22 and a second side wall 112 away from the mounting plate 22; the first side wall 111 is provided with a second operating hole 115 at a position corresponding to the mounting hole 223, and the second side wall 112 is provided with a third operating hole 116 at a position corresponding to the second operating hole 115, and an operating tool can pass through the third operating hole 116 and the second operating hole 115 to operate the third screw 2231; the second side wall 112 is provided with a fourth operating hole 117 at a position corresponding to the second strip hole 13, and an operating tool can pass through the fourth operating hole 117 to operate the second screw 131. The fourth operating hole 117 is set as a strip through hole, and the fourth operating hole 117 extends toward the first direction, so that when the connecting portion 1 is adjusted to any position in the first direction, the operating tool can pass through the fourth operating hole 117 to operate the second screw 131.

[0091] Furthermore, if Figure 8 As shown, the diameter of the second operating hole 115 is smaller than the diameter of the nut of the third screw 2231, so that the nut of the third screw 2231 is confined between the first accommodating space 141 and the mounting plate 22, so that the third screw 2231 can be installed on the window frame.

[0092] Furthermore, if Figure 6 As shown, the inner wall of the frame-shaped structure 11 is provided with a second receiving groove 118 at the location of the second strip-shaped hole 13, and the second receiving groove 118 is used to receive the nut of the third screw 2231, so that the nut of the third screw 2231 does not interfere with the driving device 190. Furthermore, the second receiving groove 118 is opened to the end surface of the frame-shaped structure 11, so as to facilitate the processing and forming of the second receiving groove 118.

[0093] In some embodiments, Fig. 9 As shown, in order to ensure the position accuracy of drilling holes on the window frame, the utility model provides a drilling positioning plate 3, wherein the drilling positioning plate 3 is provided with two positioning holes 31, and the two positioning holes 31 are arranged vertically to indicate the correct drilling position on the window frame. The center distance between the two positioning holes 31 is equal to the center distance between the two mounting holes 223 of the mounting plate 22. The drilling positioning plate 3 has a positioning edge 32. The distance between the positioning hole 31 and the positioning edge 32 is set to a predetermined distance. The positioning edge 32 is abutted against the window glass so that the distance between the positioning hole 31 and the glass is the predetermined distance. The predetermined distance is slightly smaller than an initial distance. The initial distance can be understood as the distance between the outermost side of the driving wheel 1901 and the mounting hole 223 in the first direction when the driving device 100 is not installed on the window. This ensures that when the driving device 100 is installed on the window frame, the driving wheel 1901 can abut against the window glass, and there is a certain positive pressure between the driving wheel 1901 and the window glass. At this time, it is only necessary to fine-tune the position of the driving device 190 to make the positive pressure reach an appropriate size. This is quick and convenient, and the efficiency of adjusting the positive pressure is improved.

[0094] Furthermore, if Fig. 22 As shown, a movable bracket 1902 is disposed inside the driving device 190, and the movable bracket 1902 is elastically supported by four springs 1903. The movable bracket 1902 can move in the opposite direction to the first direction to compress the spring 1903. The driving wheel 1901 is supported by the movable bracket 1902. When the driving wheel 1901 abuts against the window glass, the driving wheel 1901 is compressed toward the inside of the driving device 190 under the abutment of the glass, driving the movable bracket 1902 to compress the spring 1903, and the elastic force provided by the spring 1903 increases, thereby gradually increasing the positive pressure. Among them, since the driving wheel 1901 can move in the first direction, the adjustment stroke between the driving device 190 and the window glass is increased, which is conducive to the user to accurately adjust the positive pressure. The inventor of the utility model has verified through multiple tests that when the driving wheel 1901 is pressed by the window glass and shrinks inward by 4.8mm, the positive pressure between the driving wheel 1901 and the window glass can meet the needs of most casement windows. At this time, the friction between the driving wheel 1901 and the glass can reach 50N, thereby ensuring that there is no slip between the driving wheel 1901 and the glass. Therefore, when designing the drilling positioning plate 3, it is necessary to make the predetermined distance 4.8mm smaller than the initial distance, so as to ensure that when the driving device 190 is installed on the window frame, the driving wheel 1901 is pressed by the window glass and shrinks inward by 4.8mm. At this time, the positive pressure has reached an appropriate size, and then the adjustment part 2 is fine-tuned according to the actual movement of the window to make the positive pressure reach the best. Further, the predetermined distance is 23.8mm.

[0095] Furthermore, if Fig. 9 As shown, the back of the drilling positioning sheet 3 is pasted with double-sided tape (not shown in the figure). Before drilling, the drilling positioning sheet 3 is first pasted to the window frame of the first window 210, and the positioning edge 32 is ensured to abut against the glass of the second window 220, and then a hole is drilled at the location of the positioning hole 31. After the drilling is completed, the drilling positioning sheet 3 is peeled off, and finally the mounting plate 22 is installed on the window frame. The drilling positioning sheet 3 not only improves the position accuracy of the drilling, but also improves the drilling efficiency.

[0096] It is worth noting that the drilling positioning sheet 3 provided in the present invention is only Figure 5-Figure 9 The embodiment is described in detail as an example, but the drilling positioning sheet 3 can also be applied to other embodiments (such as Figure 1-Figure 4 , Figure 10-Figure 20 The embodiment shown in the figure) will not be described in detail here.

[0097] In one embodiment, if Fig.10 As shown, this embodiment and Figure 5-Figure 9 The difference between the illustrated embodiments is that the second side wall 112 of the frame structure 11 does not have the fourth operation hole 117, and the third operation hole 116 is set as a circular through hole. Since the second side wall 112 does not have the fourth operation hole 117, the second screw 131 is a hexagon socket screw, and the user can use an "L"-shaped hexagon socket wrench to directly operate the second screw 131 from the inside of the frame structure 11. The third screw 2231 is a cross screw, and the second operation hole 115 and the third operation hole 116 are both circular through holes. The user can use a cross screwdriver to pass through the third operation hole 116 and the second operation hole 115 to operate the third screw 2231.

[0098] In some embodiments of the present invention, Figure 1-Figure 10 as well as Figure 15-Figure 20 In the embodiment shown, the user needs to remove the driving device 190 to adjust the adjusting part 2. After the adjustment is completed, the driving device 190 needs to be installed on the connecting part 1 to verify whether the positive pressure meets the requirements. If it does not meet the requirements, the step needs to be repeated. This process is cumbersome and inconvenient for the user to adjust multiple times. To this end, the embodiment of the utility model provides a positive pressure adjusting member 110 that is easy to operate, such as Figure 11-Figure 14As shown, the adjustment part 2 also includes an adjustment structure 27, and the adjustment structure 27 can adjust the position of the connecting part 1 in the first direction in response to an external operation; the adjustment structure 27 includes an operating unit 271, and the operating unit 271 is used to receive the external operation, wherein the direction in which the operating unit 271 receives the external operation is different from the direction in which the mounting plate 22 is directed toward the connecting part 1, so that the operating unit 271 is not blocked by the driving device 190, and the driving device 190 does not need to be removed during the operation of the adjustment structure 27, so that the user can repeatedly adjust the position of the driving device 190 and verify whether the positive pressure reaches the optimal value, which greatly improves the operation efficiency and convenience. The direction in which the operating unit 271 receives the external operation can be understood as the direction in which the operation is applied from the outside toward the operating unit 271. In this embodiment, the direction in which the operating unit 271 receives the external operation is toward the first direction.

[0099] Furthermore, if Fig.12 and Fig.14 As shown, the mounting plate 22 is provided with a slide rail 28, and the connecting part 1 is slidably connected to the slide rail 28; the mounting plate 22 limits the displacement of the adjustment structure 27 in the first direction, and the adjustment structure 27 includes a threaded column 272, and the threaded column 272 extends toward the first direction, and the threaded column 272 is connected with the connecting part 1 so that the rotation of the threaded column 272 around the central axis can drive the connecting part 1 to produce displacement in the first direction. Wherein, the adjustment structure 27 can be a screw, a screw or other structure with a thread, and the threaded column 272 and the connecting part 1 can be matched in a manner of internal thread and external thread, ball screw or other matching manners. The adjustment structure 27 drives the connecting part 1 by rotating the threaded column 272, so that the position of the connecting part 1 in the first direction can be linearly adjusted, that is, the rotation amount of the threaded column 272 is proportional to the displacement amount of the connecting part 1, so that the user can adjust the positive pressure to an appropriate size. In one embodiment, as Fig.12 As shown, the adjustment structure 27 is configured as an adjustment screw, and a first connection protrusion 16 is protruded from one side of the connection portion 1 facing the mounting plate 22, and the first connection protrusion 16 is provided with a fourth threaded hole, and the adjustment screw passes through the fourth threaded hole, and the thread of the fourth threaded hole is adapted to the thread of the adjustment screw.

The first connection protrusion 16 is accommodated in the screw limiting groove 225, and the first connection protrusion 16 can move in the screw limiting groove 225. Fig.14 As shown, the screw limiting groove 225 includes a nut limiting groove 2251 , and the nut of the adjusting screw is placed in the nut limiting groove 2251 , and is limited in displacement in the first direction by the nut limiting groove 2251 .

[0102] The nut of the adjusting screw is provided with the operating unit 271, and the mounting plate 22 is provided with an adjusting hole 226 at a position directly opposite to the operating unit 271, so that an operating tool can pass through the adjusting hole 226 to operate the operating unit 271; the direction of the mounting plate 22 toward the connecting portion 1 is set to a second direction, and the angle between the direction of the adjusting hole 226 toward the operating unit 271 and the second direction is greater than 45°, so that the operating unit 271 is not blocked by the driving device 190. The second direction is already Fig.11 It is marked that the utility model has verified through experiments that when the angle between the direction of the adjustment hole 226 toward the operating unit 271 and the second direction is greater than 45°, the operating tool will not interfere with the driving device 190 during operation, and the operation is smoother. Fig.11 As shown, the direction of the adjustment hole 226 toward the operating unit 271 coincides with the first direction, and the angle between the first direction and the second direction is 90°, so as to improve the convenience of operation.

[0103] like Fig.13 and Fig.12As shown, the slide rail 28 is constructed as a shoulder screw 281, and the shoulder screw 281 is detachably connected to the mounting plate 22. The connecting portion 1 is provided with a sliding hole 171 at a position corresponding to the shoulder screw 281. The sliding hole 171 is sleeved on the shoulder screw 281 and can slide along the shoulder screw 281. When the shoulder screw 281 is removed from the mounting plate 22, the connecting portion 1 can be removed from the mounting plate 22. In this embodiment, the shoulder screw 281 is used as the slide rail 28, so that the assembly and disassembly of the connecting portion 1 and the mounting plate 22 become easier. A shoulder screw 281 is installed at both ends and the middle position of the mounting plate 22 respectively, and the shoulder screw 281 is inserted into the mounting plate 22 from the side of the mounting plate 22. The connection part 1 is provided with three second connection protrusions 17 on one side facing the mounting plate 22. The three second connection protrusions 17 are respectively provided at both ends and the middle position of the connection part 1. The second connection protrusions 17 are provided with the sliding hole 171. The mounting plate 22 is provided with a fifth threaded hole 227. The shoulder screw 281 passes through the sliding hole 171 and is connected to the fifth threaded hole 227. The shoulder screw 281 includes a smooth shaft and a threaded shaft provided at the end of the smooth shaft. The threaded shaft is connected to the fifth threaded hole 227. The sliding hole 171 is a smooth through hole. The sliding hole 171 is sleeved on the smooth shaft and can slide along the smooth shaft.

[0104] Furthermore, if Fig.13 As shown, a fifth operating hole 228 is provided on the side of the mounting plate 22 at a position directly opposite to the nut of the shoulder screw 281, and the shoulder screw 281 is inserted into the mounting plate 22 through the fifth operating hole 228, and the shoulder screw 281 passes through the sliding hole 171 and is connected to the fifth threaded hole 227. The nut of the shoulder screw 281 is exposed to the fifth operating hole 228, so as to facilitate the removal of the shoulder screw 281. When the shoulder screw 281 is removed from the mounting plate 22, the connecting portion 1 can be removed from the mounting plate 22. Furthermore, the fifth operating hole 228 and the adjustment hole 226 are respectively located on both sides of the mounting plate 22, so that when the mounting plate 22 is installed on the window frame, the adjustment hole 226 faces indoors and the fifth operating hole 228 faces outdoors, so as to avoid the user confusing the fifth operating hole 228 with the adjustment hole 226.

[0105] It is worth noting that, compared with other embodiments, Figure 11-Figure 14 The illustrated embodiment also has a beneficial effect: after the connecting portion 1 is removed from the mounting plate 22 and installed again, since the positional relationship between the adjusting structure 27 and the connecting portion 1 has not changed, the position of the connecting portion 1 can be kept consistent with that before removal, thereby ensuring that the positive pressure between the driving wheel 1901 and the window glass meets the requirements without re-adjusting the position of the connecting portion 1.

[0106] Furthermore, if Fig.13 As shown, the mounting plate 22 has two mounting holes 223, and the mounting holes 223 are mounted on the window frame by seventh screws 2232.

Fig.16 and Fig.17As shown, the mounting plate 22 is provided with four mounting holes 223, and the mounting holes 223 are mounted on the window frame by means of eighth screws 2233. The mounting holes 223 are configured as countersunk holes, and the nuts of the eighth screws 2233 are sunk into the mounting holes 223, so that the connecting portion 1 can be attached to the mounting plate 22. Furthermore, the side of the mounting plate 22 facing the window frame is a plane, so that the mounting plate 22 can be not only mounted on the window frame by means of the eighth screws 2233, but can also be attached to the window frame.

[0111] Furthermore, if Fig.17 As shown, the first nut 29 is configured as a square nut, the first slide groove 229 extends from the inside of the mounting plate 22 toward the first direction to the end surface of the mounting plate 22, the first slide groove 229 forms a port 2292 on the end surface, and the square nut is placed in the first slide groove 229 through the port 2292. Extending the first slide groove 229 to the end surface of the mounting plate 22 can reduce the difficulty of processing.

[0112] In some embodiments, Figure 16-Figure 18 As shown, the mounting plate 22 is provided with a protrusion array 23 toward the connecting portion 1, and the connecting portion 1 is provided with a recess array 18 matched with the protrusion array 23. When the connecting portion 1 is attached to the mounting plate 22, the protrusion array 23 is embedded in the recess array 18 to limit the movement of the connecting portion 1 in the first direction; thereby preventing the driving device 190 from gradually moving in a direction opposite to the first direction under the abutment of the window glass, and ensuring that the positive pressure between the driving wheel 1901 and the window glass will not decrease with the increase of usage time.

[0113] When the position of the connecting portion 1 needs to be adjusted, the fourth screw 292 can be loosened from the first nut 29, so that the connecting portion 1 is disengaged from the abutment with the mounting plate 22, and the protrusion array 23 is disengaged from the recess array 18, so that the connecting portion 1 can be adjusted in the first direction;

[0114] The protrusion array 23 includes a plurality of limiting protrusions, and the recess array 18 includes a plurality of limiting recesses, and the arrangement directions of the limiting protrusions and the limiting recesses are both toward the first direction; wherein, the number of the limiting recesses is greater than the limiting protrusions, so that when the position of the connecting part 1 is adjusted in the first direction, the protrusion array 23 can still be kept in cooperation with the recess array 18.

[0115] This embodiment adopts the combination of the protrusion array 23 and the recessed array 18, so that the position of the connecting part 1 in the first direction can be adjusted in steps. Compared with other embodiments in which the connecting part 1 can only be adjusted in an infinite manner, the stepped adjustment allows the user to control the adjustment distance more accurately, that is, the user can adjust the position of the connecting part 1 one grid at a time, and have a clearer perception of the positive pressure corresponding to each grid, which is conducive to the user adjusting the positive pressure to the optimal value.

[0116] Furthermore, if Fig.16 As shown, the protrusion arrays 23 are respectively provided at the positions near the two ends of the mounting plate 22, and the recess arrays 18 are respectively provided at the positions corresponding to the protrusion arrays 23 of the connecting portion 1, so that the limiting effect of the protrusion arrays 23 is stronger, and the driving device 190 is further prevented from gradually moving in the direction opposite to the first direction under the abutment of the window glass. Furthermore, each protrusion array 23 includes three rows and four columns of limiting protrusions, and each recess array 18 includes three rows and seventeen columns of limiting recesses, so that when the connecting portion 1 is adjusted in the first direction, the limiting protrusions can still be kept embedded in the limiting recesses.

[0117] It is worth noting that the structures related to the protrusion array 23 and the recess array 18 provided in this embodiment are only shown in FIG. Figure 15-18 The embodiment shown is described in detail for the sake of example, but the related structure of the protrusion array 23 and the recess array 18 can also be applied to Figure 1-Figure 14 The embodiments shown will not be described in detail here.

[0118] In some embodiments, Fig.16 and Fig.17 As shown, two groups of scale scales 24 are provided on one side of the mounting plate 22 facing the connecting portion 1, wherein the direction of one group of scale scales 24 facing the other group of scale scales 24 is perpendicular to the first direction, and the scale scales 24 are used to indicate the adjustment amount of the connecting portion 1 in the first direction, so that the user can accurately control the adjustment amount, which is conducive to the user adjusting the positive pressure to the optimal value. And because the direction of one group of scale scales 24 facing the other group of scale scales 24 is perpendicular to the first direction, the adjustment amounts at the upper and lower ends of the connecting portion 1 can be kept consistent, thereby preventing the connecting portion 1 from tilting.

[0119] Furthermore, if Fig.17As shown, the scale ruler 24 is arranged on the side of the mounting plate 22 facing the connecting part 1, and each group of scale rulers 24 includes 15 scale lines 241 arranged in parallel, and numbers 242 arranged at both ends of each scale line 241, and the value of the number 242 gradually increases from the edge of the mounting plate 22 toward the first direction. When the position of the connecting part 1 is adjusted in the first direction, the positional relationship between the connecting part 1 and the mounting plate 22 is obtained by judging the corresponding relationship between the front end surface of the connecting part 1 and each scale line 241. Furthermore, the number 242 located at the upper end of the scale line 241 is arranged upside down, so that when the mounting plate 22 is installed upside down, it is convenient for the user to read the value of the number 242.

[0120] Furthermore, the scale ruler 24 can be used in conjunction with the relevant structure of the above-mentioned protrusion array 23. Specifically, in the first direction, the spacing between two adjacent scale lines 241 is equal to the spacing between two adjacent limit protrusions, so that when the connecting part 1 adjusts the distance of a limit protrusion toward the first direction, the scale ruler 24 changes exactly one grid, so that the user can adjust the position of the connecting part 1 one grid at a time. At the same time, the user can refer to the scale ruler 24 to accurately obtain the adjustment amount of the connecting part 1, thereby improving the adjustment accuracy and efficiency.

[0121] It is worth noting that the scale scale 24 related structure provided in this embodiment is only used as an example. Figure 15-18 The embodiment shown is an example for detailed description, but the scale scale 24 related structure can also be applied to Figure 1-Figure 14 as well as Figure 19-20 The embodiments shown will not be described in detail here.

[0122] In some embodiments, Fig.19 and Fig. 20 As shown, the mounting plate 22 is provided with a plurality of second threaded holes 251, and the connecting portion 1 is connected to the second threaded holes 251 by a fifth screw 2511, so that the connecting portion 1 is detachably connected to the mounting plate 22; the fifth screw 2511 can switch the connection relationship with each of the second threaded holes 251, so that the position of the connecting portion 1 in the first direction changes;

[0123] The second threaded holes 251 are arranged in at least two rows, and the arrangement direction of the second threaded holes 251 in each row is oriented toward a third direction, and the third direction is inclined to the first direction, so that when the fifth screw 2511 switches between the two second threaded holes 251 in the same row, the position change of the connecting part 1 in the first direction is very small, thereby achieving fine adjustment of the position of the connecting part 1 in the first direction. Fig. 20 Winning bid.

[0124] In a specific embodiment, Fig. 20 As shown, the spacing between two adjacent second threaded holes 251 in the same column is 6 mm, and the angle between the third direction and the first direction is 80°. When the fifth screw 2511 switches between the two adjacent second threaded holes 251 in the same column, the position change of the connecting part 1 in the first direction is only 6 mm × cos80°, which is about 1.04 mm, that is, the adjustment step of the connecting part 1 in the first direction is about 1.04 mm, thereby achieving fine-tuning of the position of the connecting part 1 in the first direction.

[0125] It should be noted that, since the adjustment step length of the connecting part 1 in the first direction is small, the corresponding adjustment stroke of each column of the second threaded holes 251 is short. In order to increase the total adjustment stroke of the connecting part 1 in the first direction, the second threaded holes 251 are arranged into at least two columns, including a first column of threaded holes and a second column of threaded holes. The second column of threaded holes is arranged on the side of the first column of threaded holes facing the first direction. The function of the second column of threaded holes is to continue the adjustment stroke of the first column of threaded holes. Specifically, the fifth screw 2511 can be switched from the last hole position of the first column of threaded holes to the first hole position of the second column of threaded holes, so that the fifth screw 2511 can continue to switch positions along the second column of threaded holes, and then the connecting part 1 is adjusted in the first direction, so that the adjustment stroke of the connecting part 1 is extended. In a preferred embodiment, Fig. 20 As shown, the second threaded holes 251 are arranged in two rows. In other embodiments, the second threaded holes 251 can be arranged in three rows, four rows or more rows, so that the adjustment stroke of the connecting part 1 is longer.

[0126] Furthermore, if Fig. 20 As shown, the mounting plate 22 is provided with two threaded hole arrays 25, which are distributed near the two ends of the mounting plate 22, and the connecting portion 1 is respectively connected to the two threaded hole arrays 25 by two fifth screws 2511. The two threaded hole arrays 25 are arranged in the same manner, and each threaded hole array 25 includes two rows of the second threaded holes 251.

[0127] Furthermore, if Fig. 20As shown, the connecting portion 1 includes a frame-shaped structure 11, the frame-shaped structure 11 is used to be sleeved on the driving device 190, the frame-shaped structure 11 is provided with a third countersunk hole 129, and the fifth screw 2511 is connected to the second threaded hole 251 through the third countersunk hole 129 from the inner side of the frame-shaped structure 11. The nut of the fifth screw 2511 is accommodated in the third countersunk hole 129 to avoid interference between the nut of the fifth screw 2511 and the driving device 190. Further, the frame-shaped structure 11 includes a first side wall 111 close to the mounting plate 22 and a second side wall 112 away from the mounting plate 22, and the second side wall 112 is provided with an eighth operating hole 128 at a position corresponding to the fifth screw 2511, and a user can use a tool to pass through the eighth operating hole 128 to operate the fifth screw 2511.

[0128] In some embodiments, Figure 3 , Figure 5 , Fig.10 , Fig.11 , Fig.15 and Fig.19 As shown, the upper and lower ends of the frame structure 11 are respectively provided with snap-in grooves 122 for snapping into the driving device 190. Figure 4 , Fig.21 and Fig. 22 As shown, one end of the driving device 190 is provided with a fixed buckle 19041, and the other end is provided with a movable buckle 19042, and the movable buckle 19042 can be pushed to retract inward. Figure 4 The embodiment shown is an example. When installing the drive device 190, first snap the fixed buckle 19041 into the snap-in groove 122 at the upper end of the frame structure 11, and then snap the movable buckle 19042 into the snap-in groove 122 at the lower end of the frame structure 11; when disassembling the drive device 190, first push the movable buckle 19042 upward to disengage the movable buckle 19042 from the snap-in groove 122, and then detach the drive device 190 outward from the frame structure 11. Furthermore, the first side wall 111 of the frame structure 11 is provided with a third threaded hole 123, and the second side wall 112 is provided with a first countersunk hole 124 at a position directly opposite to the third threaded hole 123. The driving device 190 is provided with a through hole 19043 at a position corresponding to the third threaded hole 123. The through hole 19043 transversely penetrates the left and right ends of the driving device 190. A long screw 125 passes through the first countersunk hole 124 and the through hole 19043 and is connected to the third threaded hole 123 to prevent the driving device 190 from being abutted by the window glass and detached from the frame structure 11.

[0129] It is worth mentioning that Figure 1As shown, the positive pressure regulating member 110 needs to be installed on the inner window frame of the sliding window to prevent rain from wetting the driving device 190. There are two types of sliding windows on the market: the left window is close to the room or the right window is close to the room. The positive pressure regulating member 110 provided by the utility model can be installed vertically by 180° to adapt to the above two types of sliding windows, and the positive pressure regulating member 110 is designed to be a vertically symmetrical structure, so that the driving device 190 can be installed upside down on the positive pressure regulating member 110, and then when the driving device 190 is installed on the above two types of sliding windows, it can be ensured that the driving device 190 is installed on the window close to the room and the driving wheel 1901 is located at the lower side of the driving device 190.

Since the positive pressure regulating member 110 is a vertically symmetrical structure, the driving device 190 can be vertically flipped 180° relative to the positive pressure regulating member 110 for installation, thereby keeping the direction of the driving device 190 unchanged, the driving wheel 1901 is still located on the lower side of the driving device 190, and the button 19045 is still located on the upper side of the driving device 190.

Furthermore, the plug-in through hole 126 located at the upper end of the drive device 190 and the first countersunk hole 124 located at the upper side of the drive device 190 are both provided with a silicone dust plug (not shown in the figure).
