[0040] 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 herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0041] Refer to Figures 1-5, the present utility model discloses an adjustable lower boosting structure, comprising: an outer sleeve 10, which is used to sleeve on the pulley link 1301 of the lifting sliding window and door system, and the outer sleeve 10 is detachably connected to the pulley link 1301 of the lifting sliding window and door system as a whole; a boosting member 20, which is used to sleeve on the pulley link 1301 of the lifting sliding window and door system, and the boosting member 20 is slidably connected to the pulley link 1301 of the lifting sliding window and door system; the boosting member 20 includes a boosting sleeve 201 and a boosting stop 202, the outer sleeve 10 is sleeved outside the boosting sleeve 201, and the outer sleeve 10 is slidably connected to the boosting sleeve 201, and the boosting stop 202 is used to be fixedly connected to the window sash 140 of the lifting sliding window and door system as a whole; an elastic element 30, which is used to sleeve on the pulley link 1301 of the lifting sliding window and door system, and the elastic element 30 is embedded inside the outer sleeve 10, one end of the elastic element 30 is connected to the outer sleeve 10, and the other end of the elastic element 30 is connected to the boosting sleeve 201.

[0042] It should be noted that when it is necessary to adjust the axial distance between the outer sleeve 10 and the boosting member 20, remove the outer sleeve 10 and sleeve it on the appropriate position of the pulley link 1301 of the lifting sliding window and door system, axially close to or away from the boosting member 20. After completing the adjustment of the axial distance between the two, connect and fix the outer sleeve 10 and the pulley link 1301 of the lifting sliding window and door system; when the adjustable lower boosting structure is in use, the outer sleeve 10 can move along with the pulley link 1301 of the lifting sliding window and door system. During the movement of the outer sleeve 10, the elastic element 30 compresses and stores energy or releases energy, so as to achieve boosting.

[0043] In the adjustable lower boosting structure of the present utility model, the outer sleeve 10 can be disassembled and assembled. By adjusting the axial distance between the outer sleeve 10 and the boosting member 20, the stretching degree of the elastic element 30 is changed, so as to adjust the magnitude of the boosting force. And the elastic element 30 is arranged between the outer sleeve 10 and the boosting member 20. The pulley link 1301 of the lifting sliding window and door system and the outer sleeve 10 respectively provide internal and external support for the elastic element 30, which can keep its operation stable and avoid skewing and deformation after long-term use.

[0044] Specifically, one end of the elastic element 30 can abut against or be connected to the outer sleeve 10 by means of welding, clamping, etc., and the other end of the elastic element 30 can abut against or be connected to the boosting sleeve 201 by means of welding, clamping, etc., as long as the elastic element 30 can provide a boosting force to achieve boosting.

[0045] In the embodiment of the present utility model, the boosting sleeve 201 and the boosting stop 202 are made separately, and the elastic element 30 drives the boosting sleeve 201 to abut against the boosting stop 202.

[0046] Or in other embodiments, the boosting sleeve 201 and the boosting seat 202 are separately formed, and the boosting sleeve 201 and the boosting seat 202 are connected and fixed into one body.

[0047] It should be noted that the installation method of the boosting sleeve 201 is subject to the function of enabling the elastic element 30 to boost.

[0048] In the embodiment of the present utility model, the elastic element 30 is a spring, such as a tension spring.

[0049] In the embodiment of the present utility model, the adjustable lower boosting structure further includes a first set screw 40. A first connection hole 50 is provided on the outer sleeve 10. The first set screw 40 cooperates with the first connection hole 50. The first set screw 40 passes through the first connection hole 50 to detachably connect the outer sleeve and the pulley link 1301 of the lifting sliding window system into one body.

[0050] Specifically, when it is necessary to adjust the axial distance between the outer sleeve 10 and the boosting member 20, loosen the first set screw 40, axially approach the boosting member 20 or axially move away from the boosting member 20. After completing the adjustment of the axial distance between the two, lock the first set screw 40 to complete the connection and fixation of the outer sleeve 10 and the pulley link 1301 of the lifting sliding window system. Thus, the outer sleeve 10 can move along with the pulley link 1301 of the lifting sliding window system. During the movement of the outer sleeve 10, the elastic element 30 compresses and stores energy or releases energy, thereby realizing boosting.

[0051] If the window sash 140 is heavier, the axial distance between the outer sleeve 10 and the boosting member 20 can be reduced, so that the elastic element 30 is compressed more tightly, and thus the boosting force will be larger; if the window sash 140 is lighter, the axial distance between the outer sleeve 10 and the boosting member 20 can be increased, so that the elastic element 30 is compressed more loosely, and thus the boosting force will be smaller.

[0052] In the embodiment of the present utility model, the adjustable lower boosting structure further includes a second set screw 60. Second connection holes 70 are provided on both the boosting seat 202 and the window sash of the lifting sliding window system. The second set screw 60 passes through the second connection hole 7 to connect and fix the boosting seat and the window sash 140 of the lifting sliding window system into one body.

[0053] In the embodiment of the present utility model, the adjustable lower boosting structure further includes an auxiliary screw 80. Third connection holes 90 are provided on both the outer sleeve 10 and the boosting sleeve 201. The auxiliary screw 80 passes through the third connection hole 90 to detachably connect the outer sleeve 10 and the boosting sleeve 201.

[0054] Specifically, before installation, the elastic element 30 and the booster sleeve 201 are inserted into the outer sleeve 10. Then, the booster sleeve 201 is compressed to a position where it fits the outer sleeve 10, so that the elastic element 30 is compressed to the initial compression limit state. Finally, the auxiliary screw 80 is installed to lock the booster sleeve 201 and the outer sleeve 10. The outer sleeve 10 cannot move before the auxiliary screw 80 is removed, so that the adjustable lower booster structure maintains the initial compression limit state. After installation is completed, the auxiliary screw 80 is removed, and the outer sleeve 10 can move, and the adjustable lower booster structure is converted to the working state.

[0055] In the embodiment of the present utility model, the outer sleeve 10, the elastic element 30, and the booster member 20 are all provided with fourth connection holes 100 for passing through the pulley link 1301 of the lifting sliding window system.

[0056] Specifically, the outer sleeve 10, the elastic element 30, and the booster sleeve 201 are coaxially arranged.

[0057] Refer to Figures 6-7 , the present utility model discloses a lifting sliding window system, including the adjustable lower booster structure of any one of the above.

[0058] In the embodiment of the present utility model, the lifting sliding window system further includes a handle 110, a transmission 120, a pulley structure 130, a window sash 140, and a slide rail 150. The handle 110 and the transmission 120 are arranged on the side of the window sash 140, and the pulley structure 130 and the slide rail 150 are arranged at the bottom of the window sash 140. The handle 110 is in transmission connection with the transmission 120, and the transmission 120 is in transmission connection with the pulley structure 130. The pulley structure 130 includes a pulley link 1301. The handle 110 drives the transmission 120 to move downward, thereby driving the pulley structure 130 to rise and separate from the slide rail 150, so that the window sash 140 descends. The handle 110 drives the transmission 120 to move upward, thereby driving the pulley structure 130 to descend and cooperate with the slide rail 150, so that the window sash 140 rises to achieve pushing and pulling.

[0059] The lifting sliding window system in the present utility model adopts an adjustable lower booster structure to provide a boosting force for the transmission 120 and assist in lifting the window sash 140, which is convenient for users to operate.

[0060] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
