Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and relates to a built-in sunshade insulated glass product, particularly a locking structure for a built-in sunshade insulated glass product. Background Technology

[0002] Built-in shading insulated glass products are composite functional glass products in which a shading curtain is installed inside a sealed insulated pane of glass. The shading elements include shading curtains and louvers. The extension and retraction of the shading elements within the double glazing are mainly controlled manually or electrically to increase or decrease the shading area of ​​the architectural shading product.

[0003] In existing technology, the extension and retraction of sunshades inside insulated glass windows are mainly achieved through the following structure: a guide rail is fixed inside the glass window, and a slider is installed inside the guide rail; a handle is installed outside the insulated glass window, and magnets are installed on both the handle and the slider. The handle and the slider are attracted to each other through the glass. When a person moves the handle, it moves the slider along the guide rail, thereby realizing the extension and retraction of the built-in sunshade. When the sunshade is used as a shading louver, the louver can also be flipped and adjusted for light by using the handle and the slider.

[0004] For example, Chinese patent application (CN104653081B) describes a hollow glass product with built-in sunshade. According to the attached drawings of the patent specification, a spacer frame is sandwiched between two layers of glass, and sealant is applied to the outside of the spacer frame and between the two layers of glass. The blade assembly and the blade control device are located between the two layers of glass, with both the blade assembly and the blade control device located inside the spacer frame and the blade control device located outside the blade assembly. The handle is located outside the glass and is correspondingly set with the blade control device. Sliding the handle drives the blade control device to work, realizing the extension, retraction, and flipping of the blade assembly.

[0005] Insulating glass windows are typically manufactured in a factory and then transported to the site for installation on the wall. During transportation, to prevent damage to the sunshade, it is often retracted. To ensure the sunshade remains in the retracted position during transportation, the applicant proposes a lifting and locking structure (CN209724177U) for built-in sunshade insulating glass products. This lifting and locking structure includes a fixing block and a locking pin. The fixing block is located within the sliding groove of the sliding block and is positioned below the retractable sliding block. The fixing block is fixedly connected to the fixing components of the built-in sunshade insulating glass product. The locking pin passes through the fixing block, and a connector sleeved on the locking pin is attached to the retractable sliding block. The lifting and locking structure positions the retractable sliding block at its lowest point of travel, with the built-in sunshade in the retracted state and the lifting rope taut.

[0006] In the above solution, a connector is provided in the lifting slider and a fixing block is added in the slider groove. The setting of the connector and the fixing block restricts the movement distance of the lifting slider, which may affect the opening and closing of the sunshade and reduce the user experience. At the same time, the structure of setting the fixing block in the slider groove increases the manufacturing cost of the insulated glass. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a locking structure for insulated glass products with built-in sunshades. The technical problem this invention aims to solve is: how to improve the user experience and reduce the manufacturing cost of insulated glass.

[0008] The purpose of this utility model can be achieved through the following technical solution: a locking structure for a built-in sunshade hollow glass product, including a side column frame with a sliding groove, wherein a sliding slider for controlling the retraction and extension of the built-in sunshade is installed in the sliding groove, characterized in that the retraction and extension slider is provided with a mounting groove for locking the retraction and extension slider, a snap-fit ​​block matching the mounting groove is slidably connected in the mounting groove, and a locking groove is provided on the sliding groove that can snap into the snap-fit ​​block, wherein the snap-fit ​​block snaps into the locking groove to lock the retraction and extension slider in the sliding groove.

[0009] In this solution, the locking block is installed inside the retractable slider, eliminating the need for an additional locking structure on the slider. The locking groove is installed on the sliding track, eliminating the need for a fixing block within the track. From the time the insulated glass leaves the factory until transportation, the locking block remains locked within the locking groove, keeping the retractable slider locked. Once the insulated glass is installed and when using a sunshade, the locking block is removed from the locking groove via a magnetic component on the outside of the insulated glass, and the retractable slider is no longer locked by the locking block. This solution ensures the retractable slider remains locked while maintaining its normal and unrestricted range of motion, guaranteeing the smooth retraction and extension of the sunshade and improving the user experience. Furthermore, reducing the need for fixing blocks lowers the manufacturing cost of the insulated glass.

[0010] In the locking structure of the aforementioned insulated glass unit with built-in sunshade, the sliding groove includes a base plate and a side plate connected to the base plate, and the locking slot is located on the base plate or the side plate. Since the locking slot is located on the base plate or the side plate, there is no need to install a fixing block inside the sliding groove, thus reducing the manufacturing cost of the insulated glass unit.

[0011] In the locking structure of the above-mentioned built-in sunshade insulated glass product, the sliding groove includes a base plate, the base plate is provided with a vertical plate, and the locking groove is located on the vertical plate.

[0012] In the locking structure of the aforementioned built-in sunshade insulated glass product, the locking block is cylindrical, and its cross-section is circular, polygonal, or a combination of curves and straight lines. The cylindrical shape of the locking block allows it to slide within the mounting groove and prevents it from easily shifting.

[0013] In the locking structure of the aforementioned built-in sunshade insulated glass product, the retractable slider is further provided with an elastic limiting block. The end of the elastic limiting block has a stop protruding towards the locking block. When the retractable slider is locked, the stop blocks against the side wall of the locking block. When the retractable slider is unlocked, the stop blocks against the end face of the locking block near the bottom of the groove. During transportation of the built-in sunshade insulated glass product, the stop blocks restrict the movement of the locking block, preventing it from retracting towards the locking groove when the glass window is subjected to external force, thus unlocking the locking ring. This ensures that the locking block is more stable in the locking groove when the retractable slider is locked. When the locking block disengages from the locking groove, the stop blocks against the end face of the locking block, preventing the locking block from contacting the groove during the movement of the retractable slider, thus ensuring the stability of the retractable slider's movement.

[0014] In the locking structure of the above-mentioned built-in sunshade insulated glass product, the stop block is provided with a guide slope, and the guide slope faces the mounting groove.

[0015] In the locking structure of the aforementioned built-in sunshade insulated glass product, the locking block is made of iron or neodymium iron boron permanent magnet material. Making the locking block of iron or permanent magnet material allows the permanent magnet strip to be subjected to greater force during use, resulting in a good locking effect.

[0016] In the locking structure of the aforementioned built-in sunshade insulated glass product, the retractable slider is equipped with a guide block, which slides on the vertical plate. The guide block helps stabilize the movement of the retractable slider.

[0017] In the locking structure of the above-mentioned built-in sunshade insulated glass product, the locking block is a nail-shaped structure, and the locking block includes a nail head.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This solution ensures that the retraction slider is locked while maintaining its normal range of movement without restriction, thus ensuring the smooth retraction and extension of the sunshade and improving the user experience. At the same time, reducing the number of fixing blocks can lower the manufacturing cost of insulated glass.

[0020] 2. The permanent magnet strip in this solution has a columnar structure, which is not easy to deviate during use and is simple to process and form, which not only ensures the reliability of the locking structure but also reduces manufacturing costs. Attached Figure Description

Detailed Implementation

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] Example 1

[0041] like Figure 1 As shown, the built-in sunshade insulated glass product includes two layers of glass 1, with a spacer frame sandwiched between the two layers of glass 1. A sealant (omitted in this embodiment) is wrapped around the outside of the spacer frame and between the two layers of glass, thereby forming a sealed space. The handle in this example is also omitted.

[0042] like Figure 2 As shown, in this embodiment, the sunshade inside the insulated glass is a sunshade curtain 8, but it can also be a sunshade venetian blind as described in the background art. The spacer frame is formed by horizontal and vertical spacers 11. A side column frame 2 is connected to the inside of the vertical spacer 11. A sliding groove 3 is provided in the side column frame 2, and a sliding block 4 for controlling the opening and closing of the built-in sunshade curtain is installed in the sliding groove 3. The upper end of the sunshade curtain 8 is fixed to the roller 10, and the lower end of the sunshade curtain 8 is fixed to the counterweight 9. Cover plates 12 are provided on both the horizontal and vertical spacers 11. The cover plates 12 are used to cover the roller 10, the sliding groove 3, and the sliding block 4, etc., to improve the aesthetics of the built-in sunshade insulated glass product. A rotating rope is connected to the roller, and the rotating rope is connected to the retraction slider 4. A magnet (not shown) is installed in the retraction slider 4. The handle on the outside of the glass is also magnetic. Moving the handle controls the up and down movement of the retraction slider 4 within the slide groove 3, which, in conjunction with the counterweight 9, causes the roller 10 to rotate, ultimately realizing the retraction and deployment of the sunshade 8. The above structure is existing in the field of built-in sunshade insulated glass products. Figure 2 The transfer rope is not shown.

[0043] like Figure 3 , Figure 4 , Figure 5 and combined Figure 6As shown, the inner surface of the slide 3 includes a base plate 32, on which a vertical plate 31 is provided. A notch is opened in the middle of the vertical plate 31 to form a locking groove 7. The position of the locking groove 7 is determined according to the retracted position of the lower end of the sunshade curtain 8 during transportation of the built-in sunshade insulated glass product. An installation groove 41 is provided on the retractable slider 4, and a snap-fit ​​block 5 is placed in the installation groove 41. The snap-fit ​​block 5 is made of neodymium iron boron magnet. As an alternative, the snap-fit ​​block 5 can be made of iron. The retractable slider 4 is also provided with an elastic limiting block 6. The inner side of the elastic limiting block 6 is flush with the inner wall of the mounting groove 41. This flushness can be regarded as an extension of part of the structure of the mounting groove 41. The end of the elastic limiting block 6 is also provided with a stop 61 protruding towards the locking block 5. The stop 61 is provided with a guide slope 62 facing the mounting groove 41. The guide slope 62 facilitates the locking block 5 to enter the locking groove. When the locking block 5 is located, it can be locked in the locking groove 7 to lock the retractable slider 4. The locking block 5 is a columnar structure and the cross-section of the locking block 5 is rectangular. The shapes of the mounting groove 41 and the locking groove 7 are matched with the shape of the locking block 5.

[0044] The snap-fit ​​block 5 can be installed into the locking groove 7 in the following ways: Before encapsulating the built-in sunshade hollow glass product, determine the retraction position of the lower end of the sunshade curtain 8 and the position of the retractable slider 4 in the slide groove 3. The snap-fit ​​block 5 in the mounting groove 41 can be pushed into the locking groove 7 by manually pressing the rod; or the snap-fit ​​block 5 can be magnetically attracted into the locking groove 7 from the back of the slide groove using a magnet. The guide slope on the stop block 61 guides the movement of the snap-fit ​​block 5, provided the magnetic force between the magnet and the snap-fit ​​block 5 is sufficient to overcome the resistance from the stop block 61; or the snap-fit ​​block 5 can be pushed into the locking groove from the front of the slide groove by the repulsion of like poles using a magnet. When the snap-fit ​​block 5 enters the locking groove 7, the resistance can be reduced by holding the retractable slider or the sunshade curtain 8.

[0045] After the built-in sunshade hollow glass product is encapsulated, the locking block 5 can be moved into the locking groove 7 by the handle and magnet. Before encapsulation, the locking block 5 is placed in the mounting groove 41. After the built-in sunshade hollow glass product is encapsulated, the retractable slider 4 is moved to the designated position by the handle. This position can be marked on the glass. Under the action between the handle and the retractable slider 4, the sunshade 8 no longer moves. The locking block 5 needs to overcome the resistance of the stop block 61 to enter the locking groove 7. As long as the magnetic force between the magnet and the locking block 5 is sufficient to overcome the resistance of the stop block 61, the locking block 5 can enter the locking groove 7.

[0046] like Figure 4 , Figure 7 and Figure 8As shown, when the latching block 5 is partially located in the locking groove 7, the retractable slider 4 is in a locked state. At this time, the elastic limiting block 6 bends elastically, and the stop block 61 abuts against the side wall of the latching block 5 to prevent the latching block 5 from disengaging from the locking groove 7. When the retractable slider 4 needs to be unlocked (unlocking here means that the retractable slider is no longer locked by the latching block 5), a magnet is used outside the glass window 1 to move the latching block 5, and the latching block 5 disengages from the locking groove 7. In order to reduce the resistance when the latching block 5 disengages from the locking groove 7, the handle can interact with the retractable slider 4 at this time. After the latching block 5 disengages from the locking groove 7, the retractable slider 4 is in a movable state. The guide slope 62 on the stop block 61 blocks the end face of the latching block 5, so that the latching block 5 will not touch the slide groove 3 during the movement of the retractable slider 4, thus ensuring the stability of the movement of the retractable slider 4.

[0047] This solution ensures the locking of the retractable slider 4 while maintaining its normal range of movement unrestricted by the locking groove 7 and the latching block 5, thus guaranteeing the normal retraction and extension of the sunshade 8 and improving the user experience. Simultaneously, reducing the number of fixing blocks lowers the manufacturing cost of the insulated glass unit 1. This locking structure can be applied to double-glazed units as well as triple-glazed units with two cavities.

[0048] Example 2

[0049] like Figures 9 to 12 As shown, the structures of Embodiment 2 and Embodiment 1 are basically the same, with the difference being that the structures of the mounting groove 41, the snap-fit ​​block 5, the locking groove 7, and the elastic limiting block 6 are somewhat different. In this embodiment, the cross-section of the snap-fit ​​block 5 is circular, and the shapes of the mounting groove 41 and the locking groove 7 match those of the snap-fit ​​block 5, that is, the cross-sections of the mounting groove 41 and the locking groove 7 are both circular. No vertical plate 31 is provided inside the sliding groove 3, and the locking groove 7 is provided on the base plate 32.

[0050] Example 3

[0051] like Figures 13 to 15 As shown, the structure of this embodiment is basically the same as that of embodiment two. The difference is that in this embodiment, the locking groove 7 is located on the left side plate 33 of the slide groove 3, and the mounting groove 41 is inclinedly set on the retractable slider 4. When the locking block 5 is locked, the locking block 5 is located in the locking groove 7, the elastic limiting block 6 is bent, and the stop block 61 abuts against the locking block 5.

[0052] Example 4

[0053] like Figure 16 and Figure 17As shown, the structure of this embodiment is basically the same as that of Embodiment 1. The difference is that in this embodiment, the vertical plate 31 is located on the side plate near the slide groove 3, the mounting groove 41 is located at the lower left end of the retractable slider 4, and the retractable slider 4 is also provided with a guide block 42, which slides on the vertical plate 31. The guide block 42 is beneficial to the stability of the movement of the retractable slider 4.

[0054] Example 5

[0055] As an alternative, the snap-fit ​​block 5 structure in Embodiments 1 to 5 can adopt a nail-like structure. The snap-fit ​​block 5 includes a nail head, an installation groove 41 and a locking groove 7 that match the shape of the snap-fit ​​block 5.
