Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a lifting and sliding door and window system with a power-assisting mechanism. Background Art

[0002] The existing lifting and sliding door and window system uses the principle of lever theory to drive the actuator by rotating the handle, and then drives the pulley mechanism set at the bottom of the window sash to lift or lower the window sash, thereby achieving the lifting or lowering of the window sash.

[0003] Chinese patent CN219931937U discloses an adjustable buffer booster for a lifting and sliding door transmission, which is provided with a positioning seat, which is pressed against the active part, and the positioning protrusions and positioning grooves are respectively provided on the end face of the positioning seat and the end face of the active part, each positioning protrusion and each positioning groove are distributed at equal angles along the circumferential direction, and the rear side surfaces of the positioning protrusions and positioning grooves are all set vertically or tilted in the opposite direction to the front side surfaces to ensure that the active part can only perform unidirectional rotational movement relative to the positioning seat. However, this technical solution only provides a boosting structure at the transmission position, and because the active part needs to cooperate with the rack and the positioning seat, two tooth shapes need to be processed on the active part, which not only increases the processing difficulty but also reduces the strength of the active part. In addition, the positioning seat is also gear-shaped, which is relatively expensive.

[0004] Chinese patent CN118208111A discloses an intermediate pulley mechanism with a power-assist assembly and a heavy-duty lift-and-slide door and window. The power-assist assembly comprises a second support member and a first elastic member. The second support member is connected to the bottom of the door and window body, and the first elastic member engages with the second support member and the pulley assembly, respectively. When the door and window body is in a sinking state, the pulley assembly compresses the first elastic member. When the pulley assembly is driven to lift the door and window body, the first elastic member rebounds and provides thrust to the pulley assembly. The second support member is an L-shaped support block and comprises a horizontally arranged first support plate and a vertically arranged second support plate. The first support plate is screwed to the bottom of the door and window body. The first elastic member is disposed between the second support plate and the pulley assembly, and engages with the second support plate and the pulley assembly, respectively. However, the heavy-duty lift-and-slide door and window in this technical solution only has a power-assist structure on the pulley mechanism, and the thrust of the power-assist structure cannot be adjusted, which has certain limitations.

[0053] The utility model provides a first adjustable assisting structure 20 to assist the movement of the transmission bar 101, and a second adjustable assisting structure 40 to assist the movement of the pulley connecting rod 301. Moreover, the assisting force of the first adjustable assisting structure 20 and the second adjustable assisting structure 40 can be adjusted, and can be suitable for window sashes 50 of different weight specifications and the needs of different users.

[0054] In an embodiment of the present invention, the lifting and sliding door and window system with a power-assisting mechanism also includes a window sash 50 and a handle 60, which is in transmission connection with the transmission 10, and the handle 60 and the transmission 10 are both arranged on the side of the window sash 50; the transmission 10 also includes a transmission panel 102, which is fixedly connected to the window sash 50, and the transmission bar 101 is movably connected to the transmission panel 102.

[0055] In order to better realize the pushing and pulling of the window sash 50 , a slide rail 70 cooperating with the pulley structure 30 is provided at the bottom of the window sash 50 .

[0056] In this way, the first adjustable power-assisting structure 20 performs power-assisting along the longitudinal direction, and the second adjustable power-assisting structure 40 performs power-assisting along the transverse direction, and the power-assisting effect is better.

[0057] See Figure 3-Figure 6 In the embodiment of the present utility model, the first adjustable power-assisting structure 20 includes a fixing member 201, a first elastic element 202 and an adjusting unit 203. The adjusting unit 203 is arranged on the fixing member 201, and the fixing member 201 is connected and fixed to the transmission panel 102; the adjusting unit 203 includes a rotating member 2031, a moving member 2032 and a stop member 2033. The moving member 2032 is provided with a plurality of adjusting teeth 2034 and a plurality of stop teeth 2035. The plurality of adjusting teeth 2034 are arranged along the moving member 2032. One side of the moving part 2032 is arranged axially, and multiple stop teeth 2035 are arranged axially along the other side of the moving part 2032. The rotating part 2031 cooperates with the adjusting tooth 2034 to drive the moving part 2032 to move forward by rotating the rotating part 2031. The stop part 2033 cooperates with the stop tooth 2035 to limit the reverse movement of the moving part 2032; the first elastic element 202 is arranged between the moving part 2032 and the transmission bar 101 to realize the elastic connection between the transmission bar 101 and the moving part 2032.

[0058] It should be noted that Figure 4-Figure 5 For example, the forward movement of the moving member 2032 refers to the counterclockwise rotation of the rotating member 2031 driving the moving member 2032 to move upward, and the reverse movement of the moving member 2032 refers to the clockwise rotation of the rotating member 2031 driving the moving member 2032 to move downward.

[0059] The first adjustable power-assisting structure 20 utilizes the adjustment unit 203 to achieve adjustable thrust, which can be suitable for window sashes 50 of different weight specifications and the actual needs of users. By rotating the rotating part 2031, the movable part 2032 is driven to move forward to adjust the telescopic adjustment of the first elastic element 202. The stop member 2033 cooperates with the stop tooth 2035 to limit the reverse movement of the movable part 2032 during the telescopic adjustment of the first elastic element 202, thereby ensuring the stability of the telescopic adjustment of the first elastic element 202; and the adjusting teeth 2034 and the stop teeth 2035 are both arranged along the axial direction of the movable part 2032, reducing the processing difficulty of the movable part 2032 and the rotating part 2031, and reducing production costs.

[0060] It should be noted that during adjustment, the end of the first elastic element 202 connected to the transmission bar 101 remains stationary. The user can use a screwing tool to drive the rotating part 2031 to rotate or directly rotate the rotating part 2031 to drive the first elastic element 202 to axially extend and retract through the movable part 2032, thereby adjusting the thrust; after completing the thrust adjustment, the first adjustable power-assisting structure 20 can be used in conjunction with the transmission 10. When in use, the first elastic element 202 follows the movement of the transmission bar 101 to achieve thrust.

[0061] Preferably, for ease of operation, the rotating member 2031 is disposed close to the transmission bar 101 ; the fixing member 201 is fixed so as to achieve elastic propulsion, for example, the fixing member 201 can be fixed on the transmission panel 102 .

[0062] Specifically, one end of the first elastic element 202 and the end of the movable part 2032 can be connected by welding, clamping, bonding or elastic abutment, and the other end of the first elastic element 202 and the transmission bar 101 can be connected by welding, clamping, bonding or elastic abutment, so that the movable part 2032 can drive the first elastic element 202 to extend and retract, and the first elastic element 202 can provide a boosting force for the transmission bar 101.

[0063] In an embodiment of the present invention, the rotating member 2031 is arranged near the side where the adjusting tooth 2034 is located. The rotating member 2031 is a dial wheel. The rotating member 2031 is arranged on the dial wheel and includes a rotating shaft and a dial block. The dial block is arranged on the side of the rotating shaft. The rotating shaft and the dial block are connected as a whole. An adjusting tooth groove for inserting the dial block is formed between the adjusting teeth 2034.

[0064] In an embodiment of the present utility model, the stop tooth 2035 and the stop member 2033 are both arranged at an angle, the stop member 2033 is plate-shaped or sheet-shaped, and the stop member 2033 is arranged close to the side where the stop tooth 2035 is located, and a stop tooth groove for inserting the stop member 2033 is formed between two adjacent stop teeth 2035; when the rotating member 2031 drives the moving member 2032 to move forward, the stop member 2033 slides over the back of the tooth of the stop tooth 2035 and is inserted into the stop tooth groove; when the moving member 2032 moves in the reverse direction, the stop member 2033 abuts against the stop tooth 2035 to form a lock.

[0065] In an embodiment of the present utility model, the first adjustable power-assisting structure 20 also includes a back-recoil spring 2036, one end of which is connected and fixed to the fixing member 201, and the other end of the back-recoil spring 2036 is pressed on one end of the back-recoil member 2033, so that one end of the back-recoil member 2033 is pressed on the back-recoil tooth 2035 and / or the back-recoil tooth groove, and the other end of the back-recoil member 2033 is suspended to form a pressing end 2037, and the middle part of the back-recoil member 2033 is rotatably connected to the fixing member 201.

[0066] Specifically, when the adjustment unit 203 is used for adjustment, the rotating member 2031 rotates counterclockwise for one circle to drive the moving member 2032 to move up one tooth position, each tooth position being one gear position, and the stop member 2033 prevents the moving member 2032 from moving down, and the distance between the moving member 2032 and the booster seat 204 is shortened by one tooth position compared to the previous fixed position. The first elastic element 202 installed between the moving member 2032 and the booster seat 204 is compressed by one more tooth position of the moving member 2032, and the thrust of the first elastic element 202 is increased compared to the previous position, thereby achieving different gears. Adjustment of the position; when the user wants to reduce the thrust of the first elastic element 202, the user presses the pressing end 2037 of the stop member 2033, so that the stop member 2033 overcomes the elastic force of the stop spring 2036 and moves away from the moving member 2032. At this time, the moving member 2032 can move downward, and the moving member 2032 moves back to its original position under the action of the first elastic element 202; after completing the resetting of the moving member 2032, the user releases the pressing end 2037 of the stop member 2033, and the stop member 2033 continues to be pressed on the stop tooth 2035 and / or the stop tooth groove under the elastic force of the stop spring 2036.

[0067] After the lifting and sliding door and window system is installed, the handle 60 is turned to perform the lifting and lowering operations. If the resistance when turning the handle 60 is large, the rotating part 2031 can be turned to adjust the moving part 2032 to move forward, and the distance between the moving part 2032 and the booster seat 204 can be continuously shortened to increase the thrust of the first elastic element 202, thereby changing the operating force of the handle 60 to achieve the required operating experience; if the operating force feels too light, the boosting force of the first elastic element 202 has been adjusted too large, and the pressing end 2037 of the stop member 2033 can be pressed to make the moving part 2032 move in the opposite direction and return to its original position. At this time, the first elastic element 202 also returns to its original compressed state, and then the boosting force of the first elastic element 202 is adjusted again from the original position of the moving part 2032.

[0068] Since the retaining member 2033 is arranged at an angle, the retaining member 2033 can extend out of the fixing member 201 at an angle, thereby forming a pressing end 2037 with a larger area, which is convenient for the user to operate.

[0069] In the embodiment of the present invention, the first elastic element 202 is a spring, such as a tension spring.

[0070] In the embodiment of the present utility model, the fixing member 201 includes a mounting plate 2011 and a cover plate 2012, the mounting plate 2011 and the cover plate 2012 are connected and fixed, and a mounting cavity is formed between the mounting plate 2011 and the cover plate 2012, and the first elastic element 202 and the adjustment unit 203 are both arranged in the mounting cavity; a first slide groove 2013 is provided on the mounting plate 2011, and a first protrusion 2038 is provided on the moving member 2032, and the first protrusion 2038 is connected to the first slide groove by the first protrusion 2038. The cooperation of 2013 realizes the sliding connection between the moving part 2032 and the mounting plate 2011; the first adjustable boosting structure 20 also includes a boosting seat 204, and the first elastic element 202 is connected and fixed to the transmission bar 101 through the boosting seat 204; a second slide groove 2014 is provided on the cover plate 2012, and a second protrusion 205 is provided on the boosting seat 204, and the sliding connection between the boosting seat 204 and the cover plate 2012 is realized through the cooperation of the second protrusion 205 and the second slide groove 2014.

[0072] See Figure 7-11 In an embodiment of the present utility model, the second adjustable power-assisting structure 40 includes an outer sleeve 401, a booster 402 and a second elastic element 403. The outer sleeve 401, the booster 402 and the second elastic element 403 are all sleeved on the outside of the pulley link 301, and the outer sleeve 401 is detachably connected to the pulley link 301 to change the axial distance between the outer sleeve 401 and the booster 402; the booster 402 is slidingly connected to the pulley link 301, and the booster 402 includes a booster sleeve 4021 and a booster block seat 4022.

[0073] It should be noted that when it is necessary to adjust the axial distance between the outer sleeve 401 and the thrust member 402, the outer sleeve 401 is removed and mounted on the appropriate position of the pulley connecting rod 301, axially close to the thrust member 402 or axially away from the thrust member 402. After the axial distance between the two is adjusted, the outer sleeve 401 is connected and fixed to the pulley connecting rod 301; when the second adjustable power-assisting structure 40 is in use, the outer sleeve 401 can move with the pulley connecting rod 301, and during the movement of the outer sleeve 401, the second elastic element 403 is compressed to store energy or release energy, thereby achieving thrust assist.

[0074] The second adjustable power-assisting structure 40 can be disassembled and assembled into the outer sleeve 401. By adjusting the axial distance between the outer sleeve 401 and the booster 402, the telescopic degree of the second elastic element 403 is changed, thereby adjusting the magnitude of the boosting force, and the second elastic element 403 is arranged between the outer sleeve 401 and the booster 402.

[0077] It should be noted that the installation method of the boost sleeve 4021 is based on whether the boost function of the second elastic element 403 can be achieved.

[0078] In the embodiment of the present invention, the second elastic element 403 is a spring, such as a tension spring.

[0079] In an embodiment of the present utility model, the second adjustable power-assisting structure 40 also includes a first fastening screw 404, and a first connecting hole 405 is provided on the outer sleeve 401. The first fastening screw 404 cooperates with the first connecting hole 405, and the first fastening screw 404 passes through the first connecting hole 405 to detachably connect the outer sleeve 401 with the pulley connecting rod 301; and / or, the second adjustable power-assisting structure 40 also includes a second fastening screw 406, and a second connecting hole 407 is provided on the boost block seat 4022 and the window sash 50, and the second fastening screw 406 passes through the second connecting hole 407 to connect and fix the boost block seat 4022 to the window sash 50; and / or, the second adjustable power-assisting structure 40 also includes an auxiliary screw 408, and a third connecting hole 409 is provided on the outer sleeve 401 and the boost sleeve 4021, and the auxiliary screw 408 passes through the third connecting hole 409 to detachably connect the outer sleeve 401 with the boost sleeve 4021.

[0080] Specifically, when it is necessary to adjust the axial distance between the outer sleeve 401 and the thrust member 402, loosen the first fixing screw 404, move axially closer to the thrust member 402 or axially away from the thrust member 402, and after completing the axial distance adjustment between the two, lock the first fixing screw 404 to complete the connection and fixation between the outer sleeve 401 and the pulley connecting rod 301, so that the outer sleeve 401 can move with the pulley connecting rod 301, and during the movement of the outer sleeve 401, the second elastic element 403 is compressed to store energy or release energy, thereby achieving thrust.

[0081] If the window sash 50 is heavier, the axial distance between the outer sleeve 401 and the booster 402 can be shortened so that the second elastic element 403 is compressed more tightly, thereby increasing the boosting force; if the window sash 50 is lighter, the axial distance between the outer sleeve 401 and the booster 402 can be increased so that the second elastic element 403 is compressed more loosely, thereby decreasing the boosting force.

[0082] Specifically, before installation, the second elastic element 403 and the boost sleeve 4021 are installed into the outer sleeve 401, and then the boost sleeve 4021 is compressed to a position that fits with the outer sleeve 401, so that the second elastic element 403 is compressed to the initial compression limit state. Finally, the auxiliary screw 408 is installed to lock the boost sleeve 4021 and the outer sleeve 401. Before removing the auxiliary screw 408, the outer sleeve 401 cannot move, so that the second adjustable boost structure 40 maintains the initial compression limit state; after the installation is completed, the auxiliary screw 408 is removed, the outer sleeve 401 can move, and the second adjustable boost structure 40 is switched to the working state.

[0083] In the embodiment of the present invention, the outer sleeve 401 , the second elastic element 403 and the booster 402 are all provided with a fourth connecting hole 410 for passing the pulley connecting rod 301 .

[0084] Specifically, the outer sleeve 401 , the second elastic element 403 and the boosting sleeve 4021 are coaxially arranged.
