Description

Technical Field

[0001] The invention relates to the technical field of energy-saving doors and windows, and specifically discloses a lifting and rotating adjustment mechanism for a double-layer insulating glass built-in blind. Background Art

[0002] Double-layer insulating glass built-in blinds are blinds that are installed as a whole inside the insulating glass and use magnetic force to control the blinds inside the insulating glass. Existing double-layer insulating glass built-in blinds usually have an internal magnetic adjustment mechanism inside the profiles on both sides, and external magnetic control blocks are set on the outside of the profiles on both sides. The two external magnetic control blocks are used to control the lifting and lowering of the blinds and the rotation of the curtain blades, respectively, to realize the adjustment function of the blinds.

[0003] For example, the invention patent with application number 202010641945.7 discloses a hollow glass blind, which includes a window frame, a plurality of blinds arranged in the window frame, a counterweight plate connected to the bottom of the blind at the bottom, two adjacent blinds are connected by a connecting rope, the blind at the bottom is connected to the counterweight plate by a connecting rope, a traction rope for pulling the blind is provided in the window frame, the traction rope passes through a plurality of blinds and is connected to the counterweight plate, cavities are provided in the window frames at both ends of the blinds, a controller for controlling the movement of the traction rope is provided in the cavity, an adjustment cavity is provided in the window frame below the blinds, and the adjustment cavity is connected to the cavity. The hollow glass blind disclosed in this patent is a blind that has an adjustment mechanism for adjusting the lifting and lowering of the blinds and the rotation of the curtain blades respectively arranged in the profiles on both sides. Although the two important adjustment functions of the built-in blinds are realized, blinds of this structure have the following disadvantages. First, the side profiles are wider than those of traditional glass windows, resulting in a smaller window area; second, the side profiles need to be equipped with corresponding transmission structures, resulting in a complex internal structure; third, the outer surfaces of the side profiles need to be equipped with a magnetic control block, which affects the appearance of the glass window. Therefore, in view of the above shortcomings of existing hollow glass blinds, this application proposes a lifting and rotating adjustment mechanism for double-layer hollow glass built-in blinds that can effectively solve the above technical problems. Summary of the invention

[0004] The present invention aims to provide a lifting and rotating adjustment mechanism for a double-layer insulating glass built-in blind, so as to realize simultaneous control of the lifting and lowering of the built-in blind and the rotation adjustment of the curtain blades by only one magnetic control operating unit outside a side end profile.

[0006] As a further configuration of the above scheme, the magnetic control operating part includes a hand-held block, the first magnetic attraction component includes a first magnet and a third magnet respectively arranged on the lifting slide and the hand-held block, and the second magnetic attraction component includes a second magnet and a fourth magnet respectively arranged at the front end of the movable pin rod and inside the hand-held block.

[0007] As a further configuration of the above solution, a storage groove is provided on the rear side of the hand-held block, the fourth magnet is arranged in the storage groove, and an operating member for realizing forward and backward movement of the fourth magnet is provided on the front side of the hand-held block.

[0008] As a further configuration of the above solution, the operating member is one of a bolt rotation structure or a reset button structure.

[0009] As a further configuration of the above solution, a pulley is provided on the lifting slide, and the pulling rope passes around the pulley and is connected to the upper profile.

[0010] As a further configuration of the above scheme, a cam shaft is provided on the rear side surface of the lifting slide, and two pendulum bars arranged in a mirror-symmetrical manner are rotatably connected to the cam shaft, and a second spring is connected between the two pendulum bars, and a locking tooth surface is provided on the outer side surface of one end of the pendulum bar that is rotatably connected to the cam shaft, and the roller is provided at the other end of the pendulum bar, and the pulling rope is connected to the upper profile after passing around the two pulleys, and a locking block is connected to the lifting slide located below the cam shaft through a third spring, and a latching tooth that acts on the locking tooth surface is provided on the upper end of the locking block, and a connecting rope in a vertical state is connected between the rear end of the movable pin rod extending out of the through slot and the locking block.

[0011] As a further configuration of the above scheme, a guide wheel is provided in the upper end profile, and the pulling rope is extended into the side end profile after being acted upon by the guide wheel and connected with the lifting slide.

[0012] As a further configuration of the above scheme, a track bar is arranged on the front side wall of the inner cavity of the profile at the side end, and a limiting sliding block that acts with the track bar is arranged on the lifting slide.

[0013] As a further configuration of the above scheme, the diameters of the threading holes and the through holes are both larger than the diameter of the transmission rope.

[0014] The lifting and rotating adjustment mechanism of the double-layer insulating glass built-in blinds disclosed in the present invention, when the blinds need to be lifted and adjusted, pulls the fourth magnet into the storage groove through the operating member, so that the force between the fourth magnet and the second magnet becomes smaller, so that the movable pin rod moves axially under the action of the first spring, and the through hole on the movable pin rod is aligned with the threading hole in the vertical direction. At this time, the transmission rope will not be pulled during the up and down movement of the lifting slide, and the blinds can be lifted and adjusted by the lifting rope and the pulling rope during the up and down movement of the lifting slide.

[0015] When the blinds need to be rotated and adjusted to change the light transmission effect, the fourth magnet is first pushed outward through the operating member, so that the distance between the fourth magnet and the second magnet becomes smaller and the magnetic attraction becomes larger. Therefore, the movable pin overcomes the force of the first spring under the action of the magnetic force and moves axially forward, and the through hole and the threading hole on the movable pin are misaligned, and the transmission rope is clamped through the two during the misalignment process, so that the transmission rope is connected and fixed to the lifting slide. Then the lifting slide is moved up or down a short distance to move the transmission rope, thereby driving the first transmission wire wheel to rotate, and then the rotation adjustment of the curtain piece is realized under the action of the rope winder and the ladder rope. In addition, during this adjustment process, the blinds can only be raised and lowered a short distance, which does not affect the lifting height of the blinds as a whole.

[0016] In order to further solve the problem of preventing the blinds from synchronously lifting and lowering by a small distance during the rotation and adjustment of the curtain blades, this patent adopts a special structural improvement. When the blinds are raised and lowered, the third spring causes the upper teeth of the locking block to be locked and fixed with the locking teeth on the swing bar, so that the pulley at the end of the swing bar only acts as a movable pulley, and the blinds can be easily adjusted during the lifting and lowering process with a lifting range of 1:2.

[0017] When the blinds are rotated and adjusted, the locking block can be pulled downward by pulling the rope during the axial forward movement of the movable pin rod and overcome the force of the third spring, thereby releasing the locking effect of the locking block on the two swing bars. After the transmission rope is fixed to the lifting slide, the two swing bars can be adjusted adaptively by approaching or opening each other, so that the lifting rope will not be pulled when the lifting slide moves up or down a short distance, so that the process of adjusting the blinds will not affect the process of adjusting the blinds, and a better adjustment effect is achieved.

[0018] Compared with the prior art, the present invention has the following beneficial effects: The lifting and rotating adjustment mechanism of the double-layer insulating glass built-in blinds disclosed by the present invention changes the built-in transmission structure of the traditional insulating glass blinds. The user can achieve the lifting and rotating adjustment of the blinds by only moving a magnetic control operating unit up and down along the side end profile. Its built-in transmission structure is simple, the design is novel and ingenious, and the use effect is excellent. At the same time, only through the design of the single-side profile transmission structure, the width ratio of the profile can be reduced, the transmission area of ​​the entire glass window is increased, and only one external operating unit is required, so that the appearance of the entire window is improved to a certain extent.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 8 , and describes the application in detail with reference to embodiments. Example 1

[0023] Embodiment 1 discloses a lifting and rotating adjustment mechanism for a double-layer insulating glass built-in blind, Figure 1 and attached Figure 2 , comprising a double-layer hollow glass window body 100, a shutter 200, a built-in adjustment mechanism and a magnetic control operating unit 400. The double-layer hollow glass window body 100 comprises a window frame composed of a profile 101, glass blocks 102 are arranged on both the front and rear sides of the window frame, and then the shutter 200 is arranged in a sealed space composed of the front and rear glass blocks 102 and the profile 101, the built-in adjustment mechanism is arranged inside the profile 101 at one side end and the profile 101 at the upper end, and the magnetic control operating unit 400 is adsorbed and attached to the front side of the profile 101 arranged at the side end and cooperates with the built-in adjustment mechanism.

[0024] Reference Figure 2 and attached Figure 3 The blind 200 includes curtain pieces 201 arranged at intervals in the upper and lower parts, ladder ropes 202 are arranged at both ends of the curtain pieces 201, and lifting ropes 203 are arranged between the curtain pieces 201. The number of the ladder ropes 202 is determined according to the width of the curtain pieces 201. The lifting ropes 203 are responsible for adjusting the lifting and lowering of the curtain pieces 201, and the ladder ropes 202 are responsible for adjusting the inclination of the curtain pieces 201.

[0025] The built-in adjustment mechanism is divided into two parts, one part is arranged in the upper profile 101, and the other part is arranged in the side profile 101. The built-in adjustment mechanism arranged in the upper profile 101 includes a rotating rod 301 arranged to rotate horizontally, and both left and right ends of the rotating rod 301 are provided with rope reels 302 that interact with the top of the ladder rope 202. The cross-sectional shape of the rope reel 302 can generate a cam shape or a waist shape, so that when the rotating rod 301 drives the rope reel 302 to rotate, one side of the ladder rope 202 can be raised and the other side can be lowered, thereby achieving the effect of adjusting the inclination angle of the curtain sheet 201. A first transmission pulley 303 is arranged at the end of the rotating rod 301 located just above the side end profile 101, a second transmission pulley 304 is rotatably arranged at the lower end of the inner cavity of the side end profile 101, and a closed-loop transmission rope 305 is arranged between the first transmission pulley 303 and the second transmission pulley 304, so that the first transmission pulley 303 and the second transmission pulley 304 can be rotated by pulling the transmission rope 305 up and down, and then the rotating rod 301 can be driven to rotate accordingly during the rotation of the first transmission pulley 303. In addition, a plurality of guide wheels 306 are arranged inside the upper end profile 101, and a pulling rope 307 is connected to the top end of the lifting rope 203, and then the pulling rope 307 is extended into the inside of the side end profile 101 through the guiding effect of the guide wheel 306 and arranged vertically downward.

[0026] Reference Figure 4 and attached Figure 5 The built-in adjustment mechanism disposed in the side end profile 101 includes a lifting slide 308, and the lower end of the pull rope 307 is directly connected to the lifting slide 308, so that the pull rope 307 is pulled by the up and down movement of the lifting slide 308, thereby realizing the up and down movement of the lifting rope 203, and achieving the lifting and lowering adjustment of the curtain 201. In addition, in order to ensure that the lifting slide 308 moves up and down stably along the inside of the side end profile 101, limit sliders 309 are also disposed on both sides of the lifting slide 308. At the same time, during the molding process of the side end profile 101, two track bars 103 adapted to the limit sliders 309 are integrally molded on the inner front side wall thereof (refer to the attached Figure 2 ).

[0027] A first magnet 310 is arranged at the upper end of the front side of the lifting slide 308, and a through slot 311 is provided inside the lifting slide 308 below the first magnet 310, and then a threading hole 312 is provided on the lifting slide 308, which is provided up and down and passes through the through slot 311, so that the transmission rope 305 passes through the lifting slide 308 along the threading hole 312, and the aperture of the threading hole 312 is larger than the diameter of the transmission rope 305, so as to avoid the transmission rope 305 from contacting and rubbing with the threading hole 312 during the up and down movement of the lifting slide 308. A movable pin 313 is connected to the through slot 311 through a first spring 324, and a second magnet 314 is connected to the front end of the movable pin 313. Under the action of the first spring 324, the second magnet 314 is received in the through slot 311 and keeps a certain distance from the front side of the lifting slide 308. At the same time, a through hole 315 axially aligned with the threading hole 312 is provided on the movable pin rod 313, so that in this state the transmission rope 305 can pass through the through hole 315 without frictional contact with the hole wall.

[0028] Reference Figure 7 and attached Figure 8 The magnetic control operation part 400 includes a hand-held block 401, a third magnet 402 adsorbed to the first magnet 310 is arranged on the upper end of the rear side of the hand-held block 401, a receiving groove 403 is provided on the rear side of the hand-held block 401 below the third magnet 402, a fourth magnet 404 is arranged in the receiving groove 403, and the end of the fourth magnet 404 and the second magnet 314 close to each other is also adsorbed to each other. An operating member 405 that can move forward and backward is arranged on the front side of the lower end of the hand-held block 401, and the end of the operating member 405 extending into the receiving groove 403 is connected to the fourth magnet 404. In the specific design, the operating member 405 can adopt a bolt rotation structure or a reset button structure, so that the fourth magnet 404 can be pushed toward the end face of the receiving groove 403 by the operating member 405, and then the movable pin 313 is adsorbed forward along the through groove 311 under the magnetic attraction of the fourth magnet 404 and the second magnet 314.

[0029] When the blinds 200 need to be raised or lowered, the user simply holds the hand-held block 401 and moves it up and down along the front side of the side profile 101. At this time, under the magnetic action of the first magnet 310 and the third magnet 402, the lifting slide 308 moves up and down inside the profile 101, and then the blinds 200 can be raised or lowered under the action of the pulling rope 307 and the lifting rope 203.

[0030] After the height adjustment of the blinds is completed, when the light transmittance of the glass window needs to be adjusted, the user first unscrews or presses the operating part 405, and under the action of the operating part 405, the fourth magnet 404 is pushed to the front end of the storage slot 403. At this time, the magnetic attraction between the fourth magnet 404 and the second magnet 314 can overcome the force of the first spring 324 to make the movable pin 313 move forward. In the process of the movable pin 313 moving forward, the through hole 315 on the movable pin 313 is misaligned with the threading hole 312, so that the transmission rope 305 is clamped in the through slot 311 through the movable pin 313 and fixed to the lifting slide 308. Then the user pulls the hand-held block 401 upward or downward for a short distance, and during the pulling process, the transmission rope 305 moves upward or downward, thereby driving the first transmission wheel 303 to rotate, and finally during the rotation of the rotating rod 301, the rope winder 302 rotates in the corresponding direction, so that the front or rear side of the ladder rope 202 moves up and down, and under the action of the ladder rope 202, the inclination angle of the curtain piece 201 is adjusted, ultimately achieving the effect of adjusting the light transmission effect of the blinds. Example 2

[0031] Example 2 discloses a lifting and rotating adjustment mechanism for a double-layer insulating glass built-in blind that is further improved and designed based on the technical solution in Example 1. The similarities between it and Example 1 will not be described again.

[0032] Reference Figure 4 , Attachment Figure 6 and attached Figure 7 In the second embodiment, a convex shaft 316 is provided at the upper end of the rear side surface of the lifting slide 308, and two mirror-symmetrical swing bars 317 rotate on the convex shaft 316, and a second spring 318 is connected between the two swing bars 317. A locking tooth surface 3171 is provided on the outer side surface of the end where the swing bar 317 is connected to the convex shaft 316, and a pulley 319 is rotatably provided at the other end of the swing bar 317, and then the pulling rope 307 is passed around the two pulleys 319 in sequence, and its end is fixedly connected to the bottom of the upper profile 101, thereby forming a transmission structure of a movable pulley.

[0033] A locking block 320 that moves up and down is slidably arranged on the rear side of the lifting slide 308 below the convex shaft 316, and a latching tooth that interacts with the locking tooth surface 3171 is arranged on the upper end of the locking block 320. A convex plate 321 is fixed on the rear side of the lifting slide 308 below the locking block 320, and then a third spring 322 is connected between the convex plate 321 and the locking block 320. A connecting rope 323 is arranged at the rear end of the movable pin 313 extending out of the through slot 311, and the connecting rope 323 is connected to the locking block 320. When the movable pin 313 is not attracted by the fourth magnet 404 and moves forward, the connecting rope 323 is in a vertical state at this time, and when the movable pin 313 is moved forward by the magnetic attraction of the fourth magnet 404, the locking block 320 can be pulled downward under the action of the connecting rope 323 and overcome the action of the third spring 322, so that the locking action between the locking block 320 and the swing bar 317 disappears.

[0034] Through the above improved design, when the blinds 200 need to be raised and lowered, the fourth magnet 404 is away from the second magnet 314, so that the through hole 315 on the movable pin 313 is aligned with the threading hole 312, and the transmission rope 305 can freely pass through the through hole 315 and the threading hole 312. At the same time, the connecting rope 323 at the outer end of the movable pin 313 is in a vertical state, and the locking block 320 is engaged with the locking tooth surface 3171 under the action of the third spring 323, so that the two swing bars 317 cannot rotate around the convex shaft 316, so the two pulleys 319 are fixed relative to the lifting slide 308. In the process of the lifting slide 308 moving up and down, the pulley 319 plays the role of a movable pulley, so that in the process of the lifting slide 308 moving up and down, the curtain piece 201 can move up and down at double the speed and distance, thereby improving the speed of the blinds lifting adjustment and making the lifting adjustment more convenient.

[0035] When the inclination angle of the curtain sheet 201 in the blind 200 needs to be adjusted to change the light transmission effect, the operating member 405 is first unscrewed or pressed to move the movable pin 313 forward, thereby fixing the transmission cable 305 and the lifting slide 308. At the same time, during the forward movement of the movable pin 313, the locking block 320 is pulled downward by the connecting rope 323 and overcomes the effect of the third spring 322, so that the locking effect between the locking block 320 and the swing bar 317 disappears. At this time, the two swing bars 317 can overcome the effect of the second spring 318 under the action of external force and rotate within a certain angle range. After the transmission rope 305 is fixed to the lifting slide 308, the user pulls the hand-held block 401 upward or downward a short distance to adjust the inclination angle of the curtain piece 201. At this time, since the two swing bars 317 can be adaptively adjusted by approaching or opening each other, the lifting rope 203 will not be pulled when the hand-held block 401 moves up and down a short distance, and the lifting height of the curtain piece 201 can be kept unchanged, so that the process of adjusting the inclination angle of the curtain piece 201 will not affect the lifting adjustment process of the curtain piece 201, and a better adjustment effect is achieved.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
