[0038] Currently, most sliding doors on the market have significant shortcomings in sound insulation, allowing external noise to easily enter the room, affecting residents' comfort and quality of life. This problem is not limited to busy urban areas; it can be a nuisance in any place that requires a quiet environment (such as residences and offices), and it also reduces the user experience and market competitiveness of the product.

[0039] This utility model proposes a double-opening sliding door.

[0040] Please see Figures 1 to 8 In one embodiment of this utility model, the double-opening sliding door 1 includes a door frame 10, two door body assemblies 20, and a sealing member 30. The door frame 10 has a receiving groove, within which a partition 11 is provided. The partition 11 divides the receiving groove into two slots arranged along the thickness direction of the door frame 10. The two door body assemblies 20 are slidably disposed one-to-one within the two slots. Each door body assembly 20 includes a door body, a sliding member 23 disposed on the door body and slidably connected to the slot, and a driving member 24 disposed on the door body and linked to the sliding member 23. The sliding member 23 is connected to the door body... The door body is limited and engaged. The driving member 24 is used to drive the door body to slide along the thickness direction of the door frame 10 on the sliding member 23, so that the door body has a first state of abutting against the partition 11 and a second state of being spaced apart from the partition 11. The sealing member 30 is provided on the door body or on the door body and the partition 11. When both door bodies are in the first state, the two door bodies are sealed and connected by the sealing member 30, and the two door bodies are sealed and connected to the partition 11 by the sealing member 30.

[0041] In the technical solution of this utility model, a partition 11 is provided in the receiving groove on the inner side of the door frame 10. The partition 11 can be integrally formed with the door frame 10, or it can be installed in the receiving groove by a later installation method. The receiving groove is divided into two grooves arranged along the thickness direction of the door frame 10. In this embodiment, two door body components 20 are provided. The two door body components 20 are slidably arranged in the two grooves one to one. That is, the two door body components 20 can slide in the corresponding grooves to open the left or right side of the door frame 10 or close the entire door frame 10. Considering that when the existing door assembly 20 is in the closed door frame 10 state, there is a gap between it and the door frame 10, which easily allows outdoor dust to enter the room, outdoor noise to easily spread into the room, and outdoor insects and animals to easily enter the room through the gap, in order to solve the above problems, in this embodiment, the door assembly 20 includes a door body and a sliding member 23 and a driving member 24 on the door body. It is worth mentioning that the sliding member 23 is in a limiting cooperation with the door body. The sliding member 23 can drive the door body to move horizontally along the width direction of the door frame 10 within the groove, and the sliding member 23 can also drive the door body to move horizontally along the thickness direction of the door frame 10 under the push of the driving member 24. For example, when the user operates the driving member 24, the driving member 24 drives the door body to move horizontally along the thickness direction of the door frame 10 at the top of the sliding member 23, so that the door body has a first state of being pressed against the partition 11 and a second state of being spaced apart from the partition 11. Considering that a small gap still exists after the door body and partition 11 are pressed together, outdoor noise can still easily enter the room, a sealing element 30 is also provided in this embodiment. Regarding the specific setting of the sealing element 30, it can be completely set on the circumferential surface of the side of the door body facing the partition 11. In this way, when the door body is in the first state, it can be pressed together with the partition 11 through the sealing element 30, so that the two are sealed together. This prevents outdoor dust or insects from entering the room through the gap between the two, and the decibel of noise transmitted from the outside to the inside will be greatly reduced. In other embodiments, the sealing element 30 can also be set on the surface of the partition 11 facing the two door bodies and on the opposite side surface of the two door bodies. In this way, when the two door bodies and the door frame 10 are in the closed state, the two door bodies can be sealed together with the door frame 10 through the sealing element 30 set on the partition 11, and the two door bodies can be sealed together through the sealing element 30 set on the opposite side surface. This design allows users to open either the left or right door assembly 20 as needed when using the double sliding door 1. Furthermore, when closing the door frame 10 using both door assemblies 20, the user can push the two door assemblies 20 to seal the partition 11 inside the door frame 10 with the sealing element 30. This makes it difficult for outdoor dust and insects to enter the room through the gap between the door assembly 20 and the door frame 10, and also effectively reduces the decibel level of outdoor noise transmitted into the room.

[0042] It is understandable that the sealing element 30 can be a rubber strip, or a rubber strip, etc., without much limitation.

[0043] In one embodiment, the sliding member 23 includes a mounting portion 231 and a sliding portion 232. The mounting portion 231 is detachably connected to the door body, and the sliding portion 232 is slidably connected to the mounting portion 231. One of the mounting portion 231 and the sliding portion 232 is provided with a guide block extending along the thickness direction of the door frame 10, and the other is provided with a guide groove (not shown in the figure) adapted to the guide block. In this embodiment, the sliding member 23 includes a mounting portion 231 and a sliding portion 232, wherein the mounting portion 231 is detachably connected to the door body. This connection can be a threaded connection, a snap-fit ​​connection, an adhesive connection, or a welded connection; no further limitations are imposed on this. The sliding part 232 is slidably connected to the mounting part 231. The sliding part 232 can reciprocate along the thickness direction of the door frame 10 relative to the mounting part 231. For example, a guide block is provided in the sliding part 232 and a guide groove is provided in the mounting part 231. It is worth mentioning that the extension direction of the guide block is consistent with the thickness direction of the door frame 10. By setting the guide block and the guide groove, the door body can avoid the problem of offset when it moves on the sliding part 232 through the mounting part 231, so that the door body can move more accurately along the thickness direction of the door frame 10 under the drive of the drive member 24.

[0044] In one embodiment, the sliding part 232 has a pulley assembly and a ball assembly. The pulley assembly is slidably connected to the groove, and the ball assembly is disposed between the guide block and the guide groove. A slide rail 12 is provided inside the groove, and the pulley assembly is slidably disposed on the slide rail 12. In this embodiment, the sliding part 232 includes a pulley assembly and a ball assembly (not shown in the figure), wherein the pulley assembly and the ball assembly act on objects located at both ends of the sliding part 232, the pulley assembly is slidably disposed inside the groove, and the ball assembly is disposed on the guide block in the above embodiment to provide sliding support for the mounting part 231, so that the drive member 24 drives the door body and the mounting part 231 to move more smoothly relative to the sliding part 232 along the thickness direction of the door frame 10. It is worth mentioning that in this embodiment, a slide rail 12 for sliding the pulley assembly is provided inside the groove.

[0045] In one embodiment, the mounting part 231 has a transmission structure, which includes a stacked toothed disc 2311 and a protrusion 2312, the toothed disc 2311 and the protrusion 2312 being eccentrically arranged; the driving member 24 includes a rack, the rack being meshed with the toothed disc 2311, the rack being used to drive the toothed disc 2311 and the protrusion 2312 to rotate synchronously, so that the protrusion 2312 abuts against the sliding part 232 and drives the mounting part 231 and the door body to move toward the partition 11. In this embodiment, the mounting part 231 further includes a transmission structure, which includes a stacked gear disc 2311 and a protrusion 2312, wherein the gear disc 2311 and the protrusion 2312 are eccentrically arranged. In this embodiment, the driving member 24 can be a rack, which can drive the gear disc 2311 to rotate. When the gear disc 2311 rotates, it will drive the protrusion 2312 to rotate simultaneously. Since the gear disc 2311 and the protrusion 2312 are eccentrically connected, when the gear disc 2311 drives the protrusion 2312 to rotate, the protrusion 2312 will abut against the sliding part 232, so that the protrusion 2312 pushes the mounting part 231 and the door body toward or away from the partition 11 with the sliding part 232 as the force point, so that the door body has the above-mentioned first state and second state, such as... Figure 2 As shown, at this time, both door bodies and the partition 11 of the door frame 10 are in a sealed and locked state, which is the first state, as shown. Figure 3 As shown, at this time, both door bodies and the partition 11 of the door frame 10 are in a spaced-out state, which is the second state, as shown. Figure 4 As shown, at this time, the two door bodies are respectively sealed to the partition 11 of the door frame 10, and the two door bodies are connected by corresponding surface seals, which is the first state, as shown. Figure 5 As shown, at this time, the two door bodies are respectively spaced apart from the partition 11 of the door frame 10, which is the second state.

[0046] In one embodiment, the door body includes an outer frame 21 and a glass panel 22, the glass panel 22 being disposed on the outer frame 21, and the outer frame 21 being disposed on the door frame 10. The outer frame 21 includes a left frame 21c and a right frame 21d disposed opposite to each other, and an upper frame 21a and a lower frame 21b disposed opposite to each other. The sliding member 23 is disposed between the lower frame 21b and the door frame 10 and / or between the upper frame 21a and the door frame 10. It is worth mentioning that in this embodiment, the sliding member 23 includes two sets, one set being disposed between the upper frame 21a and the door frame 10, and the other set being disposed between the lower frame 21b and the door frame 10. In other embodiments, the sliding member 23 may be disposed solely between the upper frame 21a and the door frame 10, or solely between the lower frame 21b and the door frame 10; no further limitations are imposed on this. In other embodiments, the left frame 21c, right frame 21d, upper frame 21a and lower frame 21b can be two adjacent frames forming a single structure, or three of them forming a single structure, or even four frames forming a single structure. No further limitations are imposed on this.

[0047] In one embodiment, the driving member 24 includes a handle structure 241 and a linkage component 242. The handle structure 241 is disposed on the left frame 21c or the right frame 21d. The handle structure 241 is pulsatorically connected to the linkage component 242, and the linkage component 242 is pulsatorically connected to the sliding member 23. In this embodiment, the driving member 24 includes a handle structure 241 and a linkage component 242. The handle structure 241 can drive the linkage component 242 to achieve transmission by rotation, thereby driving the rack in the above embodiment to drive the gear plate 2311 to rotate. The gear plate 2311 and the protrusion 2312 cooperate to drive the mounting part 231 and the door body to move closer to or away from the partition 11. It can be understood that the handle structure 241 is rotatably disposed on the door body.

[0048] In one embodiment, the linkage component 242 includes a connector 2421, a first slider 2422, a second slider 2423, a first corner transmission component 2424, a second corner transmission component 2425, a first rack 2426, and a second rack 2427. The connector 2421 includes a first transmission component and a second transmission component. The rotation axis of the first transmission component is rotatably connected to the handle structure 241. The second transmission component is disposed along the left frame 21c or the right frame 21d. The second transmission component meshes with the first transmission component for transmission. The two ends of the second transmission component are... The first slider 2422 is not connected to the first slider 2422 and the second slider 2423. The other end of the first slider 2422 is movably connected to the first corner transmission member 2424. The other end of the second slider 2423 is movably connected to the second corner transmission member 2425. The other end of the first corner transmission member 2424 is connected to the first rack 2426. The other end of the second corner transmission member 2425 is connected to the second rack 2427. Both the first rack 2426 and the second rack 2427 are connected to the slider 23.

[0049] These components work together to ensure that the double sliding door 1 is abutted or spaced from the partition 11 inside the door frame 10. The connector 2421 consists of a first transmission component and a second transmission component (not shown in the figure). The rotation shaft of the first transmission component is rotatably connected to the handle structure 241, while the second transmission component is arranged along the left frame 21c and has a first tooth that meshes with the first transmission component. Both ends of the second transmission component are slidably connected to the first slider 2422 and the second slider 2423, respectively. The other end of the first slider 2422 is movably connected to the first corner transmission component 2424. The other end of the second slider 2423 is movably connected to the second corner transmission component 2425. The first end of the first corner transmission component 2424 meshes with the first rack 2426, and the second corner transmission component 2425 meshes with the second rack 2427. Specifically, when the door body is spaced from the partition 11, the user places the handle structure 241 in a first downward-extending position. When the handle structure 241 rotates, it drives the first transmission member to rotate, which in turn drives the second transmission member to move along the left frame 21c via the first tooth. The movement of the second transmission member causes the first slider 2422 and the second slider 2423 to slide within the second transmission member. The movement of the first slider 2422 and the second slider 2423 respectively drives the first corner transmission member 2424 and the second corner transmission member 2425 to move. The first end of the first corner transmission member 2424 engages with the first rack 2426, and the second corner transmission member 2425 engages with the second rack 2427. The first rack 2426 and the second rack 2427 respectively engage with the gear plate 2311 installed in the mounting part 231 of the sliding member 23. The gear plate 2311 drives the protrusion 2312 to move the door body away from the partition 11 with the sliding part 232 as the force point, switching it from the closed state to the open state, that is, releasing the lock between the door body and the door frame 10. When closing the door body assembly, the user rotates the handle structure 241 to the second position. When the handle structure 241 rotates, it drives the first transmission component to rotate again, which in turn drives the second transmission component to move along the left frame 21c via the first tooth. The movement of the second transmission component causes the first slider 2422 and the second slider 2423 to slide in opposite directions within the second transmission component. The movement of the first slider 2422 and the second slider 2423 respectively drives the first corner transmission member 2424 and the second corner transmission member 2425 to move in opposite directions. The first end of the first corner transmission member 2424 meshes with the first rack 2426, and the second corner transmission member 2425 meshes with the second rack 2427. The first rack 2426 and the second rack 2427 respectively mesh with the gear disk 2311 installed in the mounting part 231 in the sliding member 23, so as to drive the gear disk 2311 to rotate in the opposite direction. The gear disk 2311 drives the protrusion 2312 to move the door body closer to the partition 11 with the sliding part 232 as the force point, so as to switch it from the open state to the closed state, that is, drive the door body to fit tightly with the door frame 10, ensuring that the sliding door is completely closed and well sealed.It is understood that the first corner drive 2424 and the second corner drive 2425 may be designed to include springs, linkages, or other forms of mechanical connection. They will be subjected to tensile or compressive forces as the mounting components move. It is also understood that the corner drives can transmit force by rotation or tilting, changing their position or angle relative to the gear 2311 and the protrusion 2312.

[0050] In one embodiment, locking grooves 41 are respectively provided on opposite sides of the two grooves, and the two locking grooves 41 are inclined relative to the height direction of the door frame 10; the door assembly 20 also includes a locking member 50 provided on the door body and corresponding to the locking groove 41, and when the door body is in the first state, the locking member 50 is locked to the bottom of the locking groove 41. To achieve a locking effect when the two door bodies are respectively fitted to the left and right sides of the door frame 10, in this embodiment, locking members 50 are respectively provided on the left frame 21c of one door body and the right frame 21d of the other door body. Locking grooves 41 are opened at the positions corresponding to the two locking members 50 on the door frame 10. When the user drives the toothed disc 2311 and the protrusion 2312 to rotate through the aforementioned driving member 24, the driving member 24 will also drive the locking member 50 to move synchronously, so that the locking member 50 slides along the locking groove 41 and is limited to the bottom of the locking groove 41. It is worth mentioning that in this embodiment, the locking groove 41 is inclined relative to the length direction of the door frame 10. This setting allows the locking member 50 and the locking groove 41 to cooperate with each other to assist the driving member 24 in driving the sliding member 23 when the user drives the door body closer to or away from the partition 11 through the driving member 24.

[0051] In one embodiment, the locking groove 41 is disposed on the locking block 40, and the locking block 40 is detachably disposed in the groove; and / or, the locking member 50 includes a mounting block 51 and a locking pin 52, the mounting block 51 is detachably disposed on the door body, and the locking pin 52 is adjustablely disposed at the end of the mounting block 51 away from the door body; and / or, the locking member 50 is disposed on the first slider 2422 and / or the second slider 2423. Considering the risk of deformation that may occur when the locking groove 41 is in long-term contact with the locking block 40, in this embodiment, the locking groove 41 is set on a locking block 40, and a corresponding mounting position is provided in the groove for the locking block 40 to be installed. In this way, when the locking groove 41 is deformed and loses its locking function, it is easy to disassemble and replace the locking block 40, so that the door body can regain its locking function. Secondly, the locking component 50 includes a mounting block 51 and a locking pin 52.
