Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a side-mounted actuator and a lifting door and window system having the same. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] The existing lifting door and window system on the market uses the principle of lever theory. By rotating the handle, the transmission device is driven to move, and then the pulley mechanism set at the bottom of the door leaf is driven to lift or lower, thereby achieving the lifting or sinking of the door leaf. Among them, the handle and the transmission device are usually installed on the visible surface (front) of the sash frame, which makes the visible surface of the sash frame wider. In order to obtain a better visual effect, some merchants install it on the side of the sash frame; when the handle is installed on the side of the sash frame, it needs to be matched with a corresponding side-mounted transmission device.

[0004] In addition, the existing side-mounted actuators on the market are usually divided into two specifications and styles: left-side side-mounted actuators and right-side side-mounted actuators, which cannot be universally assembled on the left and right sides. This leads to high manufacturing and processing costs, and also increases the difficulty and quantity of stocking. Utility Model Content

[0005] In order to overcome the defects of the above-mentioned prior art, the utility model provides a side-mounted actuator and a lifting door and window system having the same. The side-mounted actuator can not only be used in conjunction with the side-mounted handle assembly, but also can be assembled on the left and right sides, thereby improving its applicability and reducing costs.

[0006] The technical solution adopted by the utility model to solve the problem is:

[0021] The slide rail is arranged below the door leaf, and the door leaf is slidably arranged on the slide rail through the pulley mechanism.

[0022] Furthermore, the pulley mechanism comprises a front lifting pulley group and a rear lifting pulley group which are respectively arranged at the bottom of the fan frame and spaced apart from each other in the front and rear directions. The front lifting pulley group and the rear lifting pulley group have the same structure and both comprise:

[0023] A lifting seat, which is used to connect with the bottom corner of the fan frame;

[0024] A pulley assembly movably cooperates with the lifting seat;

[0032] (2) The lifting door and window system of the utility model adopts a pulley made of double-row ball bearings. Under the premise of ensuring the same load-bearing capacity as a large-sized pulley, the size can be further reduced, thereby achieving a narrower visible surface of the bottom profile of the sash frame; by arranging the handle assembly and the side-mounted transmission on the same side of the sash frame, the visible surface of the side profile of the sash frame can be narrowed, thereby making the entire lifting door and window system more simple and elegant, thereby achieving a better visual effect.

[0033] (3) The lifting door and window system of the utility model is designed to have a guide groove that is tilted downward, and the lowest end of the arc is slightly higher than the arc tangent point to form a locking position. In this way, when the guide shaft is driven to slide to the lowest end of the guide groove, the guide shaft is in a force balance state under the action of the gravity of the door leaf and stops at the locking position, thereby preventing the handle assembly and the side-mounted transmission from being always subjected to tension, thereby reducing the risk of damage to components and improving the service life of components.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0058] Embodiment 1

[0059] See also Figure 1-9 The utility model first provides a side-mounted transmission device 1, which is arranged on the side of the fan frame 22, and includes a box body 11, an eccentric wheel 12, a slider 13 and a transmission bar 15. The eccentric wheel 12 is rotatably arranged in the box body 11 and includes a main shaft 121, an eccentric shaft 122 arranged on one side of the main shaft 121 and offset from the center thereof, and a transmission shaft 123 arranged on the other side of the main shaft 121. The transmission shaft 123 passes through the box body 11 and is connected to the handle 31 in a transmission manner; the slider 13 is slidably arranged in the box body 11 and is provided with a slide groove 131 matching the eccentric shaft 122. The eccentric shaft 122 is arranged in the slide groove 131 and can slide along the slide groove 131; one end of the transmission bar 15 is connected to the slider 13, and the other end thereof passes through the box body 11 and is connected to the pulley mechanism 4 in a transmission manner. Preferably, the main shaft 121, the eccentric shaft 122 and the transmission shaft 123 are all integrally formed, and the structure is more stable and has higher strength.

[0060] Therefore, when the handle 31 is rotated, the eccentric wheel 12 can be driven to rotate, and the sliding block 13 can be driven to slide through the sliding cooperation between the eccentric shaft 122 and the sliding groove 131, thereby driving the transmission bar 15 to move, and finally driving the pulley mechanism 4 to move.

[0061] Furthermore, the side-mounted transmission 1 also includes a reversing positioning assembly 14 arranged on the slider 13, and the reversing positioning assembly 14 includes a gear 141 and a first rack 142 and a second rack 143 which are arranged on both sides of the gear 141 and meshed with the gear 141 for transmission, and a first through hole 1311 and a second through hole 1312 which are respectively connected to the first rack 142 and the second rack 143 are opened on the slide groove 131. Therefore, when the gear 141 is driven to rotate, the first rack 142 and the second rack 143 can be driven to move in opposite directions, the first rack 142 can pass through the first through hole 1311 and extend into the slide groove 131, and the second rack 143 can pass through the second through hole 1312 and extend into the slide groove 131; when the first rack 142 or the second rack 143 extends into the slide groove 131, they can both abut against the eccentric shaft 122 to limit the rotation direction of the eccentric wheel 12, thereby limiting the rotation direction of the handle 31.

[0062] Therefore, the side-mounted transmission device 1 of the utility model can be used in conjunction with the side-mounted handle 31. When the handle 31 is rotated, it can sequentially drive the transmission bar 15 to move up and down through the transmission cooperation of the eccentric wheel 12 and the slider 13. It has a simple structure, convenient operation, and strong practicality. In addition, by setting the reversing positioning component 14, when the side-mounted transmission device 1 is installed on the left or right side of the fan frame 22, the first rack 142 or the second rack 143 can be selected by rotating the gear 141 to extend into the slide groove 131 and abut against the eccentric shaft 122, thereby limiting the rotation direction of the eccentric wheel 12, thereby realizing the left and right assembly of the side-mounted transmission device 1, so that there is no need to design two specifications and styles, which greatly improves its applicability and reduces costs.

[0063] Specifically, a mounting cavity 111 is provided on the box body 11, and the eccentric wheel 12 is rotatably arranged in the mounting cavity 111; the slider 13 is slidably arranged in the mounting cavity 111, and the left and right side walls of the slider 13 are respectively fitted with the left and right side walls of the mounting cavity 111; the slide groove 131 is extended along the left and right directions, and when the eccentric wheel 12 is driven to rotate, the eccentric shaft 122 can slide with the slide groove 131 to drive the slider 13 to slide up and down in the mounting cavity 111, thereby driving the transmission bar 15 to slide up and down.

[0064] Furthermore, the side-mounted transmission 1 further comprises a positioning cover 18, a third mounting groove 134 is provided on the slider 13, the reversing positioning assembly 14 is arranged in the third mounting groove 134 and is covered on the third mounting groove 134 by the positioning cover 18 to restrict the reversing positioning assembly 14 to move in the third mounting groove 134; in addition, it further comprises a cover plate 16 which is covered on the box body 11, the cover plate 16 presses the eccentric wheel 12 and the slider 13 to restrict both of them in the mounting cavity 111; a avoidance hole 161 is provided on the cover plate 16, and an adjustment part 1411 is provided on the gear 141, preferably, the adjustment part 1411 is a boss provided on the gear 141, the boss passes through the positioning cover 18 and extends out of the avoidance hole 161. Among them, an adjustment hole is provided on the boss, and the user can insert a screwdriver into the adjustment hole and rotate it to drive the gear 141 to rotate.

[0065] In this embodiment, mounting columns 112 are respectively provided at the four corners of the mounting cavity 111 on the box body 11, and third through holes 162 are respectively opened on the cover plate 16 at positions corresponding to the mounting columns 112. The cover plate 16 and the box body 11 can be connected by bolts passing through the third through holes 162 and fixed on the mounting columns 112.

[0066] More specifically, a first mounting groove 132 is formed on the slider 13 , one end of the transmission bar 15 is inserted into the first mounting groove 132 and the two are connected by a locking screw 192 to achieve fixation.

[0067] Furthermore, the side-mounted transmission 1 also includes a transmission panel 17 connected to the box body 11, and a cavity is opened in the transmission panel 17. The other end of the transmission bar 15 passes through the box body 11 and extends into the cavity, and the left and right side walls of the transmission bar 15 are respectively fitted with the left and right side walls of the concave cavity, thereby limiting the transmission bar 15 to move up and down only in the concave cavity.

[0068] Furthermore, the side-mounted transmission 1 further comprises a booster spring 191. The slider 13 is further provided with a second mounting groove 133. The booster spring 191 is arranged in the second mounting groove 133 and one end of the booster spring 191 abuts against the slider 13 and the other end abuts against the box body 11. Preferably, two booster springs 191 are provided and spaced apart from each other in the left-right direction.

[0069] When the side-mounted transmission device 1 of the present application is used, since the lower end of the transmission bar 15 is in transmission connection with the pulley mechanism 4, when the transmission bar 15 is driven to move up and down, the pulley mechanism can be driven to perform lifting and lowering actions, thereby driving the door leaf 2 to rise or sink. Since the weight of the door leaf 2 is relatively large, when the handle 31 is turned to drive the door leaf 2 to rise, the booster spring 191 can release the elastic force to drive the door leaf 2 to rise, so that there is no need to use a large force to turn the handle 31, which is more convenient.

[0070] See also Figure 6-9 The working principle of the side-mounted transmission 1 of the utility model is as follows:

[0071] When the side-mounted transmission device 1 is installed on the left side of the fan frame 22, the gear 141 is rotated to drive the first rack 142 to pass through the first through hole 1311 and extend into the slide groove 131. At this time, the eccentric wheel 12 can be restricted to rotate on the right side, that is, the handle 31 can be restricted to rotate only on the right side. When the handle 31 is driven to rotate on the right side, the eccentric shaft 122 can be slidably matched with the slide groove 131 to drive the slider 13 to move up and down, and then the transmission bar 15 moves up and down. Figure 6-7 shown.

[0072] When the side-mounted transmission device 1 is installed on the right side of the fan frame 22, the gear 141 is rotated to drive the second rack 143 to pass through the second through hole 1312 and extend into the slide groove 131. At this time, the eccentric wheel 12 can be restricted to rotate on the left side, that is, the handle 31 can be restricted to rotate only on the left side; when the handle 31 is driven to rotate on the left side, the eccentric shaft 122 can be slidably matched with the slide groove 131 to drive the slider 13 to move up and down, and then the transmission bar 15 moves up and down, such as Figure 8-9 shown.

[0073] Therefore, the side-mounted transmission 1 of the present application can be used for both left and right assembly, thereby improving its applicability and reducing costs.

[0074] Embodiment 2

[0075] See also Figure 10-19 The utility model also provides a lifting door and window system, including the side-mounted transmission device 1, the handle assembly 3, the door leaf 2, the pulley mechanism 4 and the slide rail 5 in the first embodiment, the door leaf 2 includes a leaf body 21 and a leaf frame 22, the side-mounted transmission device 1 and the handle assembly 3 are both arranged on the left side of the leaf frame 22, and the pulley mechanism 4 is arranged at the bottom of the leaf frame 22; the slide rail 5 is arranged below the door leaf 2, and the door leaf 2 is slidably arranged on the slide rail 5 through the pulley mechanism 4.

[0076] The handle assembly 3 includes a handle 31, which is connected to the transmission shaft 123 on the eccentric wheel 12, and the transmission bar 15 is in transmission connection with the pulley mechanism 4. Therefore, when the handle 31 is rotated, the pulley mechanism 4 can be driven to perform a lifting or lowering action through the transmission of the side-mounted transmission device 1 to achieve the lifting or sinking of the door leaf 2.

[0077] Furthermore, the pulley mechanism 4 includes a front lifting pulley group 41 and a rear lifting pulley group 42 which are respectively arranged at the bottom of the fan frame 22 and spaced apart from each other in the front and rear directions. The front lifting pulley group 41 and the rear lifting pulley group 42 have the same structure and are connected by a connecting rod 43.

[0078] See also Figure 12-17 The front lifting pulley group 41 includes a lifting seat 411, a pulley assembly 412 and a first transmission assembly. The lifting seat 411 is connected to the bottom corner of the fan frame 22; the pulley assembly 412 is movably matched with the lifting seat 411; one end of the first transmission assembly is connected to the transmission bar 15 in the side-mounted transmission device 1, and the other end is connected to the pulley assembly 412. The first transmission assembly is used to drive the pulley assembly 412 to move.

[0079] Among them, the pulley assembly 412 includes two fixed plates 4121 respectively arranged on the left and right sides of the lifting seat 411 and two pulleys 4122 clamped and connected between the two fixed plates 4121 and arranged with a front-to-back interval. The pulley 4122 is used to slide on the slide rail 5, and the pulley 4122 includes a pulley wheel 41221 and a double-row ball bearing 41222 arranged in the pulley wheel 41221. The pulley 4122 passes through the double-row ball bearing 41222 through a fixing pin 4123 to be fixed on the fixed plate 4121.

[0080] Therefore, the pulley 4122 made of double-row ball bearings can be made smaller in size while ensuring the same load-bearing capacity as the large-size pulley 4122, so that the visible surface of the bottom profile of the sash frame 22 can be made narrower, making it more concise and elegant, thereby achieving a better visual effect. In addition, by arranging the handle assembly 3 and the side-mounted transmission 1 on the left side of the sash frame 22, the visible surface of the side profile of the sash frame 22 can be made narrower, thereby making the entire lifting door and window system more concise and elegant, thereby achieving a better visual effect.

[0081] In this embodiment, a first fixing hole 41211 for fixing and cooperating with the end of the fixing pin 4123 is defined on the fixing plate 4121 .

[0082] Furthermore, the lifting seat 411 includes a seat body 4111 and a mounting plate 4112 disposed on the seat body 4111. The mounting plate 4112 is an L-shaped structure and includes a horizontal plate portion 41121 and a vertical plate portion 41122. The horizontal plate portion 41121 is fixed to the seat body 4111. The horizontal plate portion 41121 and the vertical plate portion 41122 are provided with a plurality of mounting holes for mounting on the fan frame 22. In addition, a guide groove 41111 is provided on the seat body 4111. A guide shaft 4124 is provided on the pulley assembly 412, which is clamped and connected between the two fixing plates 4121 and matches the guide groove 41111. The guide shaft 4124 is passed through the guide groove 41111 and can slide along the guide groove 41111. Therefore, when the pulley assembly 412 is driven to perform a lifting or lowering action, the door leaf 2 can be lifted or lowered by the sliding cooperation between the guide shaft 4124 and the guide groove 41111.

[0083] Among them, the guide groove 41111 is an arc groove arranged to be inclined downward, and the lowest terminal of the arc is slightly higher than the intersection point of the arc to form a locking position. With such arrangement, when the pulley assembly 412 is driven to descend in the direction close to the first transmission assembly until the guide shaft 4124 slides to the lowest terminal of the guide groove 41111, the guide shaft 4124 is in a force balance state and stops at the locking position, that is, the guide shaft 4124 does not exert any force on the first transmission assembly and the side-mounted transmission 1, thereby avoiding the first transmission assembly and the side-mounted transmission 1 from being subjected to tension at all times, thereby reducing the risk of damage to their components and extending their service life.

[0084] In addition, when the guide shaft 4124 descends to the lowest end of the guide groove 41111, the door leaf 2 completes the lifting action, and the pulley 4122 contacts the slide rail 5, and the bottom of the seat body 4111 is separated from the slide rail 5; when the guide shaft 4124 is driven to rise to the top of the guide groove 41111, the door leaf 2 completes the sinking action, and the bottom of the seat body 4111 abuts against the slide rail 5, and the pulley 4122 is separated from the slide rail 5.

[0085] Furthermore, it also includes a pulley rest block 418 disposed at the bottom of the seat body 4111, the pulley rest block 418 includes a main body portion that matches the shape of the slide rail 5 and a plug strip disposed on the main body portion, and a plug hole is provided at the bottom of the seat body 4111, and the plug strip is plugged and matched with the plug hole to achieve the connection between the two. Therefore, when the guide shaft 4124 is driven to rise to the top of the guide groove 41111, the main body of the pulley rest block 418 is in contact with the slide rail 5, and the door leaf 2 cannot be driven to move, thereby improving the stability of the door leaf 2.

[0086] Preferably, the pulley rest block 418 is made of nylon, thereby increasing the contact friction between it and the slide rail 5.

[0087] In this embodiment, a third fixing hole 41213 for cooperating and fixing with the end of the guide shaft 4124 is defined on the fixing plate 4121 .

[0088] Furthermore, the first transmission assembly includes a push-pull rod 414, a corner piece 413 and a connecting rod 415, and the corner piece 413 is hinged to one end of the push-pull rod 414, the seat body 4111 and one end of the connecting rod 415 respectively; the other end of the push-pull rod 414 is connected to the transmission bar 15 in the side-mounted transmission device 1, and the push-pull rod 414 is slidably disposed on the vertical plate portion 41122 of the mounting plate 4112; the other end of the connecting rod 415 extends between the two fixed plates 4121, and the connecting rod 415 and the fixed plate 4121 are connected and fixed by a fixing pin 4123.

[0089] Therefore, when the transmission bar 15 is moved to drive the push-pull rod 414 to slide upward on the vertical plate portion 41122, the corner piece 413 can be driven to rotate, thereby driving the connecting rod 415 and the fixed plate 4121 to sink in the direction close to the push-pull rod 414, and simultaneously driving the pulley 4122 and the guide shaft 4124 to sink in the direction close to the push-pull rod 414 until the pulley 4122 contacts the slide rail 5. At this time, the pulley 4122 does not move, and the guide shaft 4124 continues to descend and drives the door leaf 2 to lift by cooperating with the guide groove 41111 until the guide shaft 4124 descends to the lowest terminal of the guide groove 41111. At this time, the door leaf 2 completes the lifting action, and the pulley rest block 418 is separated from the slide rail 5.

[0090] Similarly, when the push-pull rod 414 is driven by the transmission bar 15 to slide downward on the vertical plate portion 41122, the corner piece 413 can be driven to rotate in the opposite direction, thereby driving the connecting rod 415 and the fixed plate 4121 to perform a lifting action in the direction away from the push-pull rod 414, and simultaneously driving the pulley 4122 and the guide shaft 4124 to perform a lifting action in the direction away from the push-pull rod 414, and through the cooperation of the guide shaft 4124 and the guide groove 41111 to drive the door leaf 2 to sink until the pulley rest block 418 abuts against the slide rail 5, at which time the pulley 4122 is driven to rise and can be separated from the slide rail 5, until the guide shaft 4124 rises to the top of the guide groove 41111, at which time the door leaf 2 completes the sinking action.

[0091] In this embodiment, a fifth hinge hole 4141 is provided on the push-pull rod 414, a third hinge hole 4132 is provided on the corner piece 413, and the two are hingedly connected by a latch 416; a first hinge hole 41112 is provided on the base body 4111, a second hinge hole 4131 is provided on the corner piece 413, and the two are hingedly connected by a latch 416; a sixth hinge hole 4151 is provided on the connecting rod 415, a fourth hinge hole 4133 is provided on the corner piece 413, and the two are hingedly connected by a latch 416; a fifth fixing hole 4152 is provided on the other end of the connecting rod 415, a second fixing hole 41212 is provided on the fixing plate 4121, and the two are fixedly connected by a fixing pin 4123.

[0092] Furthermore, it also includes a connector 417 disposed at the other end of the pulley assembly 412, and the connector 417 is clamped and fixed between the two fixing plates 4121; specifically, the left and right sides of the connector 417 are provided with a boss 4171, and the fixing plate 4121 is provided with a fourth fixing hole 41214, and the boss 4171 is inserted into the fourth fixing hole 41214 and clamped and fixed to achieve the connection between the two. Therefore, by providing the connector 417, it can be connected with the connecting rod 43 to achieve the connection and fixation between the front lifting pulley group 41 and the rear lifting pulley group 42.

[0093] Furthermore, it also includes a slide rail box 6 arranged under the door leaf 2, the slide rail 5 is arranged inside the slide rail box 6, and the pulley mechanism 4 at least partially extends into the slide rail box 6 and is slid on the slide rail 5. Thus, the slide rail box 6 can shield the pulley mechanism 4 to achieve "hiding" of the pulley mechanism 4, thereby improving the overall aesthetics of the door and window system.

[0094] When the guide shaft 4124 is driven to rise to the top of the guide groove 41111, the door leaf completes the sinking action and presses on the slide rail box 6. At the same time, the bottom of the lifting seat 411 abuts against the slide rail 5 through the pulley rest block 418. At this time, the pulley 4122 is separated from the slide rail 5, and the door leaf 2 cannot move. Fig.18 As shown; when the guide shaft 4124 is driven to sink to the lowest end of the guide groove 41111, the door leaf 2 completes the lifting action and disengages from the slide rail box 6, and at the same time, the pulley rest block 418 on the lifting seat 411 disengages from the slide rail 5, and the pulley 4122 contacts the slide rail 5. At this time, pushing the door leaf 2 can drive the door leaf 2 to move left and right, as shown in FIG. Fig.19 shown.

[0095] In addition, it also includes a locking transmission assembly 7 installed on the right side of the sash frame 22, and the locking transmission assembly 7 is connected to the rear lifting pulley group 42. The locking transmission assembly 7 at least includes a locking transmission bar. When the front lifting pulley group 41 is driven to move, it can be driven by the connecting rod 43 to drive the rear lifting pulley group 42 to move, and then drive the locking transmission bar to move up and down to achieve locking and unlocking of the sash frame 22.

[0096] In summary, the side-mounted actuator 1 and the lifting door and window system having the same provided by the present invention have the following beneficial effects:

[0097] (I) The side-mounted transmission device 1 of the utility model can be used in conjunction with the side-mounted handle assembly 3. When the handle 31 is rotated, it can sequentially drive the transmission bar 15 to move up and down through the transmission cooperation of the eccentric wheel 12 and the slider 13. It has a simple structure, convenient operation, and strong practicality. In addition, by providing a reversing positioning assembly 14, when the side-mounted transmission device 1 is installed on the left or right side of the fan frame 22, the first rack 142 or the second rack 143 can be selected by rotating the gear 141 to extend into the slide groove 131 and abut against the eccentric shaft 122, thereby limiting the rotation direction of the eccentric wheel 12, thereby realizing the left and right assembly of the side-mounted transmission device 1, so that there is no need to design two specifications and styles, which greatly improves its applicability and reduces costs.

[0098] (ii) The lifting door and window system of the present invention adopts a pulley 4122 made of a double-row ball bearing 41222. Under the premise of ensuring the same load-bearing capacity as the large-sized pulley 4122, the size can be further reduced, thereby achieving a narrower visible surface of the bottom profile of the sash frame 22; by arranging the handle assembly 3 and the side-mounted transmission 1 on the same side of the sash frame 22, the visible surface of the side profile of the sash frame 22 can be narrowed, thereby making the entire lifting door and window system more concise and elegant, thereby achieving a better visual effect.

[0099] (III) The lifting door and window system of the utility model is designed so that the guide groove 41111 is designed as a circular arc groove inclined downward, and the lowest terminal of the circular arc is slightly higher than the tangent point of the circular arc to form a locking position. With such a configuration, when the guide shaft 4124 is driven to slide to the lowest terminal of the guide groove 41111, the guide shaft 4124 is in a force balance state under the action of the gravity of the door leaf 2 and stops at the locking position, thereby preventing the handle assembly 3 and the side-mounted transmission 1 from being always subjected to tension, thereby reducing the risk of damage to components and improving the service life of components.
