Description

Technical Field

[0001] This application relates to the field of sliding window technology, specifically to an adaptive sealing sliding window pulley assembly. Background Technology

[0002] Traditional side-pressure windows require a complete set of hardware, including a transmission handle, transmission rod, corner mechanism, and balance bracket. This results in numerous parts, complex assembly processes, high material and labor costs, and issues such as jamming and poor wear resistance of the sliding groove in the thin-walled transmission structure. Furthermore, the wear gaps in the transmission components lead to a gradual decrease in clamping force over the years, resulting in a continuous deterioration in the sealing effect, and the clamping amount cannot be adjusted.

[0003] Traditional side-pressure windows use separate assembly structures for the handle, transmission rod, steering transmission, sliding groove, pulley housing, and sliding shaft. These assembly gaps widen with repeated use over time, making the windows prone to loosening, impacts, and abnormal noises when opened and closed.

[0004] Traditional side-pressure windows have a fixed and non-adjustable lateral pressing stroke, which can only be used with a single specification of profile and sealing strip. Furthermore, the pressing amount cannot be adjusted when the window material and sealing strip shrink due to cold, causing the sealing gap to widen and resulting in water seepage and air leakage.

[0005] In traditional side-pressure windows, lateral pressure persists throughout the entire sliding stroke of the window sash. The pulleys and the sidewalls of the track are always in a state of friction, resulting in high sliding resistance and heavy operation. The sealing strips between the frame and sash also wear out faster due to long-term repeated friction, affecting sealing performance and service life. Summary of the Invention

[0006] The purpose of this application is to provide an adaptive sealing sliding window pulley assembly, which aims to solve the technical problems of traditional side-pressure windows that rely on the handle transmission mechanism, resulting in numerous components, complex assembly, reduced and unadjustable clamping force after wear of transmission components, continuous pressure during the entire sliding stroke of the window sash, heavy sliding, and rapid wear of the rubber strip.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: An adaptive sealing sliding window pulley assembly is provided, comprising: A movable guide seat is used to connect to the bottom of the window sash; the movable guide seat has a vertical positioning shaft, and a limiting guide seat is fixedly provided on the window frame, the limiting guide seat has a horizontal sliding groove into which the vertical positioning shaft slides; the movable guide seat has a receiving cavity, the receiving cavity being at least partially connected to the bottom of the movable guide seat; A sliding seat is disposed within the receiving cavity; a roller is rotatably mounted on the sliding seat to roll in cooperation with the window frame track; a movable guide seat is capable of sliding laterally relative to the sliding seat; and a sliding guide structure is provided between the movable guide seat and the sliding seat.

When the window is closed, the vertical positioning shaft can slide into the horizontal sliding groove, and the moving guide seat can slide laterally to make the window sash press against the sealing strip, and the sliding part compresses the elastic reset structure. When the window is opened, the moving guide seat can slide laterally and reset under the combined action of the vertical positioning shaft sliding out of the horizontal sliding groove and the elastic reset structure releasing pressure.

[0008] In one possible implementation, the movable guide seat has strip-shaped holes on both opposite sides, and the sliding guide structure includes: The support rod has its two ends located in the strip-shaped holes on the corresponding sidewalls of the movable guide seat; the sliding seat has through holes that slide with the support rod. Two limiting rings are located within the receiving cavity; the two limiting rings are respectively connected to the support rod near the side wall of the movable guide seat, and the limiting rings contact the side wall of the movable guide seat to axially limit the support rod.

[0009] In one possible implementation, the transverse chute includes a guide ramp near the opening and a clamping ramp near the bottom of the chute; The angle between the guide ramp and the sliding direction of the window sash is 12 to 18 degrees, and the angle between the abutting ramp and the sliding direction of the window sash is 5 to 10 degrees.

[0010] In one possible implementation, an eccentric disk is connected to the end of the vertical positioning shaft, the eccentric disk being able to abut against the transverse sliding groove; wherein the eccentric disk is rotatable about the eccentric shaft to adjust the abutting position of the eccentric disk radially.

[0011] In one possible implementation, a sleeve is fitted onto the vertical positioning shaft, the outer peripheral wall of the sleeve has an eccentric curved surface, and the sleeve is fixed to the vertical positioning shaft by bolts; wherein, the eccentric curved surface on the sleeve can abut against the transverse sliding groove.

[0012] In one possible implementation, the elastic reset structure includes: A baffle is located within the receiving cavity and is connected to the movable guide seat; a reset cavity is formed between the baffle and one end of the receiving cavity. A sliding rod is slidably disposed within the reset cavity; the baffle has a through hole for the sliding rod to pass through, and the protruding end of the sliding rod is connected to the sliding part; the protruding end of the sliding rod has a positioning element that can contact the baffle. A spring is disposed within the receiving cavity and sleeved on the slide rod; When the window sash is closed, the spring is in a compressed, energy-storing state; when the window sash is open, the spring releases its elastic potential energy, and the positioning element contacts the baffle under the action of the spring's elastic potential energy.

[0013] In one possible implementation, the slide bar has an external thread, and the portion of the slide bar located in the reset cavity is provided with an adjusting disc, the adjusting disc having a threaded hole that mates with the thread of the slide bar; wherein the adjusting disc abuts against one end of the spring.

Compared with the prior art, the movable guide seat is fixedly connected to the window sash, and the rollers bear the weight of the window sash and roll on the window frame track to achieve normal sliding of the window sash. The window frame track can provide lateral limit for the sliding seat. When the movable guide seat moves laterally, the sliding seat has no displacement in the lateral direction. Lateral refers to the direction perpendicular to the sliding seat. When closing the window, as the vertical positioning shaft gradually slides into the horizontal sliding groove, the movable guide seat slides laterally while sliding along the length of the window sash. When the movable guide seat slides laterally, there is a relative displacement between the horizontal sliding shaft and the second guide groove, which adjusts the relative position of the first guide groove and the horizontal sliding shaft, so that the sliding part slides in the receiving cavity and compresses the elastic reset structure. At this time, the elastic reset structure is in a compressed energy storage state. When opening the window, as the vertical positioning shaft gradually slides out of the horizontal sliding groove, the movable guide seat can slide laterally. Through the cooperation of the first guide groove, the second guide groove and the horizontal sliding shaft, the elastic reset structure releases elastic potential energy, which enables the sliding part to slide and reset, thus facilitating the lateral sliding reset of the movable guide seat. Therefore, when the window is opened, the moving guide seat can slide and reset laterally under the combined action of the vertical positioning shaft sliding out of the horizontal sliding groove and the elastic reset structure releasing pressure. Through the above settings, zero lateral pressure is achieved throughout the entire process of opening and moving the window, gradual pressing is achieved at the end of closing the window, and automatic reset and centering is achieved when the window is opened, effectively avoiding window sash misalignment and jamming and abnormal wear of the sealing strip.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1-8 This application provides an adaptive sealing sliding window pulley assembly, including a movable guide seat 1, a sliding seat 2, and a sliding part 3; the movable guide seat 1 is used to connect with the bottom of the window sash; the movable guide seat 1 has a vertical positioning shaft 12, and a limiting guide seat 6 is fixedly provided on the window frame, the limiting guide seat 6 has a horizontal sliding groove 61 for the vertical positioning shaft 12 to slide into; the movable guide seat 1 has a receiving cavity 11, and the receiving cavity 11 is at least partially connected to the bottom of the movable guide seat 1. A sliding seat 2 is disposed within the receiving cavity 11; a roller 21 rotatably engages with the window frame track on the sliding seat 2; a moving guide seat 1 can slide laterally relative to the sliding seat 2; a sliding guide structure is provided between the moving guide seat 1 and the sliding seat 2; a sliding part 3 is disposed between the moving guide seat 1 and the sliding seat 2; a first guide groove 31 is provided on the sliding part 3; a second guide groove 14 is provided in the opposite direction on the moving guide seat 1; a transverse sliding shaft 22 is provided on the sliding seat 2, which slides in cooperation with the first guide groove 31 and the second guide groove 14; wherein, the sliding part 3 can slide within the receiving cavity 11; an elastic reset structure 4 is provided between the sliding part 3 and the moving guide seat 1. The window frame has a strip groove for avoiding the vertical positioning shaft 12; a limiting guide seat 6 is disposed at the end of the strip groove; the strip groove communicates with the transverse sliding groove 61.

[0022] When the window is closed, the vertical positioning shaft 12 can slide into the horizontal sliding groove 61, and the moving guide seat 1 can slide laterally so that the window sash is pressed against the sealing strip, and the sliding part 3 compresses the elastic reset structure 4; when the window is opened, the moving guide seat 1 can slide laterally and reset under the combined action of the vertical positioning shaft 12 sliding out of the horizontal sliding groove 61 and the elastic reset structure 4 releasing pressure.

[0023] This application provides an adaptive sealing sliding window pulley assembly. Compared with the prior art, the movable guide seat 1 is fixedly connected to the window sash, and the roller 21 bears the weight of the window sash and rolls on the window frame track to achieve normal sliding of the window sash. The window frame track can provide lateral limit for the sliding seat 2. When the movable guide seat 1 moves laterally, the sliding seat 2 has no displacement in the lateral direction. Lateral refers to the direction perpendicular to the sliding of the sliding seat 2. When the window is closed, as the vertical positioning shaft 12 gradually slides into the horizontal sliding groove 61, the movable guide seat 1 slides laterally while sliding along the length of the window sash. When the movable guide seat 1 slides laterally, the horizontal sliding shaft 22 has a relative displacement with respect to the second guide groove 14, thereby adjusting the relative position of the first guide groove 31 and the horizontal sliding shaft 22, so that the sliding part 3 slides in the receiving cavity 11 and compresses the elastic reset structure 4. At this time, the elastic reset structure 4 is in a compressed energy storage state. When the window is opened, as the vertical positioning shaft 12 gradually slides out of the horizontal sliding groove 61, the moving guide seat 1 can slide laterally. Through the cooperation of the first guide groove 31, the second guide groove 14 and the horizontal sliding shaft 22, the elastic reset structure 4 releases elastic potential energy, which enables the sliding part 3 to slide and reset, thereby facilitating the horizontal sliding reset of the moving guide seat 1.

[0024] Therefore, when the window is opened, the moving guide seat 1 can slide and reset laterally under the combined action of the vertical positioning shaft 12 sliding out of the horizontal sliding groove 61 and the elastic reset structure 4 releasing pressure. Through the above settings, zero lateral pressure is achieved throughout the window opening and walking process, gradual pressing is achieved at the end of the window closing, and automatic reset and centering is achieved when the window is opened, effectively avoiding window sash misalignment and jamming and abnormal wear of the sealing strip.

[0025] With the above-mentioned settings in this application, when the window is closed, the vertical positioning shaft 12 slides into the horizontal sliding groove 61, automatically triggering the lateral sliding of the moving guide seat 1 to achieve gradual compression and sealing; when the window is opened, the vertical positioning shaft 12 slides out of the horizontal sliding groove 61, and the elastic reset structure 4 releases pressure and automatically resets to the center. Throughout the entire movement, there is no lateral pressure between the moving guide seat 1 and the sliding seat 2, and the roller 21 always remains centered during movement.

[0026] This application achieves an adaptive sealing function with zero side pressure on the sliding window's travel section, progressive tightening at the closing end, and automatic centering upon opening. It eliminates the need for a handle-driven transmission mechanism, avoiding the inherent operational jamming defects of transmission structures, as well as the problems of increased clearance and tightening failure caused by wear of transmission components. It also overcomes the shortcomings of traditional structures, which cannot adapt to material thermal expansion and contraction, clearance changes due to long-term use, and the gradual decline in sealing performance. Furthermore, it solves the problems of heavy, pressure-driven sliding with traditional side-pressure pulleys, severe wear of the rubber strips, and window sash misalignment and wobbling after opening.

[0027] It should be noted that when the window is closed and the window sash is stationary, the elastic potential energy of the elastic reset structure 4 cannot drive the window sash to open. During the opening process, the window sash is in a sliding state, and the elastic potential energy released by the elastic reset structure 4 facilitates the reverse sliding reset of the transverse axis 22, thereby enabling the window sash to slide and reset laterally, reducing the possibility of the window sash sliding out of alignment. The window sash in this application can automatically reset when the window is opened, thus reducing the possibility of the window sash sliding out of alignment.

[0028] In some embodiments, such as Figures 1-8 As shown, the movable guide seat 1 has strip holes 15 on both opposite sides. The sliding guide structure includes a support rod 5 and two limiting rings 51. The two ends of the support rod 5 are respectively located in the strip holes 15 on the corresponding side walls of the movable guide seat 1. The sliding seat 2 has through holes that slide with the support rod 5. The two limiting rings 51 are both located in the receiving cavity 11. The two limiting rings 51 are respectively connected to the support rod 5 near the side wall of the movable guide seat 1. The limiting rings 51 contact the side wall of the movable guide seat 1 to axially limit the support rod 5.

[0029] The support rod 5 passes through the through hole on the sliding seat 2. The diameter of the through hole on the sliding seat 2 matches that of the support rod 5, which can provide guidance for the lateral sliding of the moving guide seat 1. The support rod 5 contacts the corresponding side wall of the moving guide seat 1 through two limiting rings 51, which can play an axial limiting role for the support rod 5 and reduce the situation where the support rod 5 protrudes from the side wall of the moving guide seat 1.

[0030] For example, both ends of the support rod 5 are coplanar with the outer side wall of the movable guide seat 1, the support rod 5 is provided with external threads, and the limiting ring 51 is provided with threaded holes; by rotating the limiting ring 51, the position of the limiting ring 51 on the support rod 5 can be adjusted so that the two limiting rings 51 contact the two side walls of the movable guide seat 1 respectively, providing axial positioning for the support rod 5.

[0031] For example, there are at least two rollers 21 inside the sliding seat 2, and the support rod 5 is located between the rollers 21. Taking two rollers 21 as an example, the support rod 5 is set between the two rollers 21. The two rollers 21 can provide support for the window sash. Setting the support rod 5 between the two rollers 21 can improve stability and reduce the occurrence of tilting of the sliding seat 2.

[0032] In some embodiments, such as Figures 1-8 As shown, the transverse sliding groove 61 includes a guide slope near the opening and a clamping slope near the bottom of the groove; wherein, the angle between the guide slope and the sliding direction of the window sash is 12 degrees to 18 degrees, and the angle between the clamping slope and the sliding direction of the window sash is 5 degrees to 10 degrees.

[0033] Setting the included angle of the guide ramp to the range of 12 to 18 degrees facilitates the smooth introduction of the vertical positioning shaft 12 into the horizontal sliding groove 61, reducing the occurrence of impact and jerking, and allowing the user to feel a smooth and quick shift when closing the window.

[0034] Setting the included angle of the inclined plane to a range of 5 to 10 degrees can provide progressive compression to the vertical positioning shaft 12, thereby gradually tightening it and reducing the possibility of sudden jamming.

[0035] Preferably, the guide slope is 15 degrees and the clamping slope is 7 degrees, which can ensure the smooth introduction of the vertical positioning shaft and realize the gradual pressing of the window sash and the end self-locking.

[0036] The top of the limiting guide seat 6 is coplanar with the slide rail at the bottom of the window frame, so the limiting guide seat 6 will not affect the sliding of the roller 21 on the slide rail; the slide rail at the bottom of the window frame has a placement groove for placing the limiting guide seat 6. The limiting guide seat 6 and the window frame can be fixed by adhesive or by bolts; when the limiting guide seat 6 and the window frame are fixed by bolts, a countersunk hole needs to be set on the top of the limiting guide seat 6, and the nut of the bolt is placed in the countersunk hole to avoid the bolt nut interfering with the sliding of the roller 21.

[0037] In some embodiments, such as Figures 1-8 As shown, an eccentric disc 13 is connected to the end of the vertical positioning shaft 12, and the eccentric disc 13 can abut against the transverse sliding groove 61. The eccentric disc 13 can rotate around the eccentric shaft to adjust its abutting position radially. The eccentric disc 13 has a through hole, and the end of the vertical positioning shaft 12 has a threaded hole. The eccentric disc 13 and the end of the vertical positioning shaft 12 are fixed together by bolts. After adjusting the position of the eccentric disc 13, tightening the bolts will fix the eccentric disc 13 onto the vertical positioning shaft 12. The contact surfaces of the vertical positioning shaft 12 and the eccentric disc 13 are both rough surfaces. Tightening the bolts strengthens the connection between the vertical positioning shaft 12 and the eccentric disc 13, reducing the offset of the eccentric disc 13. After prolonged use, the elasticity of the sealing strip will decrease. By adjusting the position of the eccentric disc 13, the movement distance of the window sash can be adjusted laterally, thereby achieving the purpose of abutting the sealing strip and improving the sealing effect.

[0038] The guide slope and the clamping slope are the working surfaces, which are in contact with the eccentric disk 13. The guide slope and the clamping slope are both set on one side of the transverse sliding groove 61, and the other side of the transverse sliding groove 61 is used to avoid the vertical positioning shaft 12 and the eccentric disk 13.

[0039] For example, a sleeve 7 is fitted on the vertical positioning shaft 12. The outer peripheral wall of the sleeve 7 has an eccentric curved surface. The sleeve 7 is fixed to the vertical positioning shaft 12 by bolts. The eccentric curved surface on the sleeve 7 can abut against the transverse sliding groove 61.

[0040] During the rotation of sleeve 7 around the vertical positioning axis, the position of the eccentric curved surface on the outer peripheral wall of sleeve 7 can be adjusted, thereby adjusting the contact position between the eccentric curved surface and the transverse sliding groove. Therefore, the distance of the transverse movement of the window sash can be adjusted, making it easier for the window sash to adapt to sealing strips of different thicknesses.

[0041] The width of the strip groove is greater than the adjustment range of the eccentric disk 13 and the eccentric curved surface. Therefore, after adjusting the position of the eccentric disk 13, it can still slide within the strip groove. After adjusting the eccentric disk 13, the initial contact position between the eccentric disk 13 and the transverse sliding groove 61 is different, allowing adjustment of the lateral movement distance of the window sash. The width of the transverse sliding groove 61 is greater than the adjustment range of the eccentric disk 13 and the eccentric curved surface. Therefore, after adjusting the circumferential position of the eccentric disk 13 and the eccentric curved surface, the transverse sliding groove 61 can accommodate both the eccentric disk 13 and the eccentric curved surface.

[0042] In some embodiments, such as Figures 1-8 As shown, the elastic reset structure 4 includes a baffle 41, a slide rod 42, and a spring 43. The baffle 41 is located in the receiving cavity 11 and is connected to the moving guide seat 1. A reset cavity is formed between the baffle 41 and one end of the receiving cavity 11. The slide rod 42 is slidably disposed in the reset cavity. The baffle 41 has a through hole for the slide rod 42 to pass through, and the protruding end of the slide rod 42 is connected to the sliding part 3. The protruding end of the slide rod 42 has a positioning element 44, which can contact the baffle 41. The spring 43 is disposed in the receiving cavity 11 and sleeved on the slide rod 42. When the window sash is closed, the spring 43 is in a compressed and stored energy state. When the window sash is open, the spring 43 releases its elastic potential energy, and the positioning element 44 contacts the baffle 41 under the action of the elastic potential energy of the spring 43.

[0043] The baffle 41 is fixed to the movable guide seat 1. One end of the spring 43 is connected to the baffle 41, and the other end of the spring 43 is connected to the slide rod 42. When the window is closed, the sliding part 3 slides away from the baffle 41. At this time, the length of the slide rod 42 in the reset cavity decreases, and the spring 43 is compressed, so the spring 43 is in a state of energy storage. After the window is closed, although the spring 43 is in a compressed and energy-storing state, the elastic potential energy of the spring 43 is insufficient to make the stationary window sash open.

[0044] During the window opening process, the elastic potential energy released by the spring 43 can cause the sliding part 3 to slide towards the baffle 41, thereby causing the moving guide seat 1 to be centered and reset, and finally completing the centering and reset of the window sash; during the subsequent sliding process, the window sash can maintain the centered sliding state, thus reducing the occurrence of window sash deviation and sliding.

[0045] For example, the protruding end of the slide rod 42 has an external thread, the positioning member 44 includes two nuts provided on the slide rod 42, the sliding part 3 has a bent portion 32, the bent portion 32 of the sliding part 3 has a through hole for the slide rod 42 to pass through, the two nuts of the positioning member 44 are respectively located on both sides of the bent portion 32 of the sliding part 3, and by the two nuts threadedly engaging with the slide rod 42, the two nuts can clamp the bent portion 32, thereby fixing the bent portion 32 of the sliding part 3 onto the slide rod 42.

[0046] When the movable guide seat 1 is centered and reset, the nut near the baffle 41 contacts the baffle 41, which limits the sliding position of the baffle 41.

[0047] In some embodiments, such as Figures 1-8 As shown, the slide rod 42 has an external thread, and the part of the slide rod 42 located in the reset cavity is provided with an adjustment plate 45. The adjustment plate 45 has a threaded hole that is threaded to engage with the slide rod 42. The adjustment plate 45 abuts against one end of the spring 43.

[0048] By rotating the adjustment disc 45, the position between the adjustment disc 45 and the baffle 41 can be adjusted, thereby adjusting the pre-compression of the spring 43 at the initial position, ensuring that the elastic force of the spring 43 can smoothly center and reset the window sash during the window opening process.

[0049] In some embodiments, such as Figures 1-8 As shown, the sliding part 3 has side plates 33 on both sides, and the sliding seat 2 can slide laterally between the two side plates 33 of the sliding part 3; the side plates 33 of the sliding part 3 respectively contact the side wall of the moving guide seat 1.

[0050] By providing side plates 33 on both sides of the sliding part 3, and having the side plates 33 contacting the side walls of the movable guide seat 1 respectively, the side plates 33 can play a lateral limiting role for the sliding part 3 during the sliding process, so that the sliding part 3 can only slide along the length direction of the movable guide seat 1, and the sliding part 3 will not slide along the width direction of the movable guide seat 1.

[0051] The movable guide seat 1 has a connecting hole, and the bottom of the window sash has a threaded hole aligned with the connecting hole. The movable guide seat 1 is fixed to the bottom of the window sash by bolts.

[0052] Furthermore, by sliding the eccentric disc 13 or the sleeve 7 against the transverse sliding groove 61, the window sash can gradually achieve the effect of pressing against the sealing strip. The structure described in this application allows the window sash to return to its centered position when the window is opened, reducing offset during subsequent sliding and thus minimizing rubbing against the track. The roller 21 in this application can be a silent roller 21, which is existing technology and will not be described further here.

[0053] This application eliminates the need for a handle or other drive structure, simplifying the assembly process and reducing costs. Under the same window sash width, the window sash in this application can accommodate thicker sealing strips. The spring 43 in this application serves as an auxiliary reset mechanism; after the window is closed, the potential energy of the compressed spring 43 is insufficient to drive the window sash to open in the opposite direction.
