[0002] The existing lifting sliding door and window system utilizes the principle of leverage. By rotating the handle, the transmission is driven to act, and then the pulley mechanism arranged at the bottom of the window sash is driven to perform lifting or lowering actions, so as to realize the lifting or lowering of the window sash.

[0003] Chinese Patent CN219931937U discloses an adjustable buffer booster for a lifting sliding door transmission. It is provided with a positioning seat that abuts against the driving member. The positioning convex blocks and the positioning grooves are respectively arranged on the end face of the positioning seat and the end face of the driving member. The positioning convex blocks and the positioning grooves are equally angularly distributed along the circumferential direction. The rear sides of the positioning convex blocks and the positioning grooves are both vertically arranged or are inclined in the opposite direction to the front side, so as to ensure that the driving member can only perform a one-way rotational movement relative to the positioning seat. However, in this technical solution, since the driving member needs to be in tooth engagement with the rack and the positioning seat, two tooth profiles need to be machined on the driving member, which not only increases the processing difficulty, but also reduces the strength of the driving member. Moreover, the positioning seat is also gear-shaped, resulting in a high cost. Summary of the Utility Model

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0037] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0039] Refer to Figures 1 - 4, the present utility model discloses a multi - gear adjustable boosting structure for a transmission, comprising: a fixing member 10; an elastic member 20; an adjusting unit 30, the adjusting unit 30 is arranged on the fixing member 10, the adjusting unit 30 includes a rotating member 301, a moving member 302 and a back - stop member 303, the moving member 302 is provided with a plurality of adjusting teeth 304 and a plurality of back - stop teeth 305, the plurality of adjusting teeth 304 are axially arranged along one side of the moving member 302, the plurality of back - stop teeth 305 are axially arranged along the other side of the moving member 302, the rotating member 301 cooperates with the adjusting teeth 304, and drives the moving member 302 to move forward by rotating the rotating member 301, the back - stop member 303 cooperates with the back - stop teeth 305 to limit the reverse movement of the moving member 302; one end of the elastic member 20 is connected to the end of the moving member 302, and the other end of the elastic member 20 is used for connecting to the transmission bar 701 of the lifting and sliding window system.

[0040] The multi - gear adjustable boosting structure for the transmission of the present utility model realizes adjustable boosting force by using the adjusting unit 30, and can be applicable to window sashes 80 of different weight specifications and the actual needs of users. By rotating the rotating member 301 to drive the moving member 302 to move forward, the elastic member 20 is telescopically adjusted. The back - stop member 303 cooperates with the back - stop teeth 305 to limit the reverse movement of the moving member 302 during the telescopic adjustment of the elastic member 20, thereby ensuring the stability of the telescopic adjustment of the elastic member 20; moreover, both the adjusting teeth 304 and the back - stop teeth 305 are axially arranged along the moving member 302, reducing the processing difficulty of the moving member 302 and the rotating member 301 and reducing the production cost.

[0041] It should be noted that during adjustment, the end of the elastic member 20 connected to the transmission bar 701 of the lifting and sliding window system does not move. The user can drive the rotating member 301 to rotate by a screwing tool or directly rotate the rotating member 301, and drive the elastic member 20 to axially expand and contract through the moving member 302, thereby adjusting the boosting force; after the boosting force adjustment is completed, the adjustable boosting structure for the transmission can be used in cooperation with the transmission. During use, the elastic member 20 moves along with the transmission bar 701 of the lifting and sliding window system to achieve boosting.

[0042] Preferably, for the convenience of operation, the rotating member 301 is arranged close to the transmission bar 701 of the lifting and sliding window system; the fixing of the fixing member 10 is based on being able to achieve the elastic boosting of the multi - gear adjustable boosting structure for the transmission. For example, the fixing member 10 can be fixed on the transmission panel 702 of the lifting and sliding window system. Both the transmission bar 701 and the transmission panel 702 are components of the transmission 70. When the lifting and sliding window system is in use, the transmission bar 701 moves relative to the transmission panel 702; the use of the transmission 70 to achieve the lifting and sliding function of the lifting and sliding window system can be realized by the prior art and will not be elaborated here.

[0043] Specifically, one end of the elastic element 20 and the end of the moving member 302 can be connected by welding, snap connection, bonding or elastic abutment, and the other end of the elastic element 20 and the transmission bar 701 of the lifting sliding window system can be connected by welding, snap connection, bonding or elastic abutment, so as to enable the moving member 302 to drive the elastic element 20 to expand and contract and the elastic element 20 to provide a boosting force for the transmission bar 701 of the lifting sliding window system.

[0044] In the embodiment of the present invention, the rotating member 301 is disposed near the side where the adjusting teeth 304 are located. The rotating member 301 is a dial, and the dial includes a rotating shaft 3011 and a dial block 3012. The dial block 3012 is disposed on the side of the rotating shaft 3011. The rotating shaft 3011 and the dial block 3012 are integrally connected, and an adjusting tooth groove 306 for the dial block 3012 to insert is formed between the adjusting teeth 304.

[0045] In the embodiment of the present invention, both the anti-backlash teeth 305 and the anti-backlash member 303 are inclined. The anti-backlash member 303 is in the shape of a plate or a sheet, and the anti-backlash member 303 is disposed near the side where the anti-backlash teeth 305 are located. An anti-backlash tooth groove 307 for the anti-backlash member 303 to insert is formed between two adjacent anti-backlash teeth 305; when the rotating member 301 drives the moving member 302 to move forward, the anti-backlash member 303 slides over the tooth back of the anti-backlash teeth 305 and inserts into the anti-backlash tooth groove 307; when the moving member 302 moves backward, the anti-backlash member 303 abuts against the anti-backlash teeth 305 to form a lock.

[0046] In the embodiment of the present invention, the multi-gear adjustable boosting structure of the actuator further includes an anti-backlash elastic sheet 308. One end of the anti-backlash elastic sheet 308 is fixedly connected to the fixing member 10, and the other end of the anti-backlash elastic sheet 308 is pressed against one end of the anti-backlash member 303, so that one end of the anti-backlash member 303 is pressed against the anti-backlash teeth 305 and / or the anti-backlash tooth groove 307. The other end of the anti-backlash member 303 is suspended to form a pressing end 309, and the middle part of the anti-backlash member 303 is rotatably connected to the fixing member 10.

[0047] Preferably, the anti-backlash elastic sheet 308 is a metal thin sheet, and the end thereof pressing against the anti-backlash member 303 has an arc portion to ensure that the anti-backlash elastic sheet 308 can be elastically pressed against the anti-backlash member 303.

[0048] It should be noted that taking Figures 1 - 2 as an example, the forward movement of the moving member 302 refers to the counterclockwise rotation of the rotating member 301 driving the moving member 302 to move upward, and the backward movement of the moving member 302 refers to the clockwise rotation of the rotating member 301 driving the moving member 302 to move downward.

[0049] Specifically, when adjusting using the adjusting unit 30, when the rotating member 301 rotates counterclockwise for one full circle, it can drive the moving member 302 to move upward by one tooth position. Each tooth position represents one gear position. The anti-retreat member 303 prevents the moving member 302 from moving downward. The distance between the moving member 302 and the boosting seat 40 is shortened by the distance of one tooth position compared to the previous fixed position. The elastic element 20 installed between the moving member 302 and the boosting seat 40 is compressed by an additional distance of one tooth position of the moving member 302, and the thrust of the elastic element 20 will increase compared to the previous position, thereby achieving adjustment of different gear positions. When the user wants to reduce the thrust of the elastic element 20, the user presses the pressing end 309 of the anti-retreat member 303, causing the anti-retreat member 303 to move away from the moving member 302 against the elastic force of the anti-retreat spring piece 308. At this time, the moving member 302 can move downward, and the moving member 302 moves back to its original position under the action of the elastic element 20. After the reset of the moving member 302 is completed, the user releases the pressing end 309 of the anti-retreat member 303, and the anti-retreat member 303 continues to be pressed tightly against the anti-retreat tooth 305 and / or the anti-retreat tooth groove 307 under the elastic force of the anti-retreat spring piece 308.

[0050] After the lifting sliding door and window system is installed, rotate the handle 60 to perform the lifting and lowering operations. If the resistance is felt to be large when rotating the handle 60, the rotating member 301 can be rotated to adjust the forward movement of the moving member 302, continuously shortening the distance between the moving member 302 and the boosting seat 40, increasing the thrust of the elastic element 20, thereby changing the operating force of the handle 60 to achieve the required operating experience. If the operating force is felt to be too light and the thrust of the elastic element 20 has been adjusted too large, the pressing end 309 of the anti-retreat member 303 can be pressed to make the moving member 302 move backward to its original position. At this time, the elastic element 20 also returns to its original compressed state, and then the thrust of the elastic element 20 is adjusted again starting from the original position of the moving member 302.

[0051] Since the anti-retreat member 303 is inclined, the anti-retreat member 303 can extend obliquely out of the fixing member 10, forming a pressing end 309 with a relatively large area, which is convenient for the user to operate.

[0052] In the embodiment of the present utility model, the elastic element 20 is a spring, such as a tension spring.

[0053] In the embodiment of the present utility model, the fixing member 10 includes a mounting plate 101 and a cover plate 102. The mounting plate 101 is fixedly connected to the cover plate 102, and an installation cavity is formed between the mounting plate 101 and the cover plate 102. The elastic element 20 and the adjusting unit 30 are both arranged in the installation cavity.

[0054] Specifically, the mounting plate 101 and the cover plate 102 can be connected and fixed by means such as welding, bonding, snap connection, or screw connection.

[0055] In an embodiment of the present utility model, a first sliding groove 103 is provided on the mounting plate 101, and a first convex block 310 is provided on the moving member 302. The sliding connection between the moving member 302 and the mounting plate 101 is realized through the cooperation of the first convex block 310 and the first sliding groove 103.

The elastic element 20 is fixedly connected to the transmission bar 701 of the lifting sliding window system through the boosting seat 40. A second sliding groove 104 is provided on the cover plate 102, and a second convex block 50 is provided on the boosting seat 40. The sliding connection between the boosting seat 40 and the cover plate 102 is realized through the cooperation of the second convex block 50 and the second sliding groove 104.

[0057] In an embodiment of the present utility model, a gear display groove 105 is provided on the mounting plate 101, and the gear display groove 105 is coaxially arranged with the moving member 302. The gear display groove 105 is used to facilitate the user to observe the gear adjustment situation.

The actuator 70 includes a transmission bar 701, an actuator panel 702 and an adjustable boosting structure for the actuator as described in any one of the above.

[0059] The lifting sliding window system of the present utility model adopts a multi-gear adjustable boosting structure for the actuator. According to different weight specifications of the window sash 80 and the actual needs of the user, the magnitude of the boosting force of the adjustable boosting structure for the actuator can be adjusted by the adjusting unit 30 to obtain different handle 60 feelings, and the stability is strong during adjustment.

[0060] It should be noted that how to drive the actuator 70 to move by rotating the handle 60 to realize the lifting of the pulley structure 90 and thus drive the lifting of the window sash 80 can be realized by the prior art and will not be elaborated herein.
