Description

Technical Field

[0001] This application relates to the field of panoramic sliding door hardware assembly technology, and in particular to a multi-point locking sliding door. Background Technology

[0002] Currently, in door and window structures, door and window hooks are used to install locks (hooks are fitted with lock bodies), while window frames are used to install lock hooks (window frames are fitted with lock hooks). Window frames and hooks are used together to connect two windows together, and can also be used to lock two windows.

[0003] Regarding the aforementioned technologies, traditional panoramic sliding door locking hardware is generally installed at the door leaf hook, using a top and bottom bolt design, with the upper and lower ends locking to the door frame, but no locking point in the middle of the door leaf. Another situation is that the lock seat is placed in the middle of the door leaf, with no locking points at the upper and lower ends of the frame. Both situations result in the inability to guarantee sealing and security. Summary of the Invention

[0004] To improve the sealing performance of panoramic sliding doors when locked, this application provides a multi-point locking sliding door.

[0005] This application provides a multi-point locking sliding door with the following technical solution:

[0006] A multi-point locking sliding door includes a frame and a side panel. A lever lock is installed on the frame. A main lock seat and several auxiliary lock seats are slidably disposed inside the frame. The lever lock is connected to the main lock seat. A main locking point and several auxiliary locking points are provided on the side panel. The auxiliary locking points are arranged along the height direction of the side panel. The main locking point corresponds to the main lock seat, and the auxiliary locking points correspond one-to-one with the auxiliary lock seats.

[0007] By adopting the above technical solution, when the sliding door is closed, the light fixture is spliced ​​with the frame, and the fork lock is activated. The fork lock moves the main lock seat and several auxiliary lock seats. The main lock seat locks with the main locking point, and the auxiliary lock seats lock with their corresponding auxiliary locking points. The main lock seat and auxiliary lock seats work together to lock the light fixture to the frame, so that the light fixture and the frame are locked tightly at multiple points. This ensures that there are locking points at the top, bottom and middle of the door leaf, improving the sealing performance of the panoramic sliding door when locked.

[0008] Optionally, the light fixture includes a connecting frame, the glass of the sliding door is fixed in the connecting frame, and side frames are installed on both sides of the connecting frame. The side frames have a first sliding groove for the sliding fork lock to slide, and the side frames also have a first mounting groove for the sliding of the main lock seat and the auxiliary lock seat.

[0009] By adopting the above technical solution, when replacing the main lock seat and the auxiliary lock seat, it is only necessary to remove one side frame to replace the main lock seat, the auxiliary lock seat and the shift fork lock, without having to disassemble the entire sliding door, which facilitates replacement and maintenance.

[0010] Optionally, a connecting rod is provided on the connecting frame, a connecting sleeve is connected to the connecting frame, and adjusting bolts are passed through the side frames. Each of the two adjusting bolts is threaded to both ends of the connecting sleeve.

[0011] By adopting the above technical solution, after the two side frames are fastened to the connecting frame, the adjusting bolts are passed through the side frames and threadedly connected to the connecting sleeve, so that the side frames and the connecting frame are tightly spliced, reducing the shaking of the side frames after long-term use and improving the sealing performance of the optical fiber.

[0012] Optionally, the fork lock includes a sliding seat, which is mounted on a side frame. A lever is slidably connected to the sliding seat, and a connecting rod is connected to the lever. One end of the connecting rod passes through the side frame on which the sliding seat is mounted. The lever is connected to the main lock seat. A sliding damper is provided on the sliding seat, and the sliding damper is in contact with the lever.

[0013] By adopting the above technical solution, the slider is moved, and the sliding block drives the connecting rod to lift or pull down, so that the connecting rod drives the main lock seat to move and lock. The sliding damping restricts the slider from sliding down due to its own gravity when it is lifted.

[0014] Optionally, the main lock seat includes a main sliding block, which is slidably disposed in the first slide groove and the first mounting groove, and the main sliding block is connected to a main hook rod;

[0015] The secondary lock seat includes a secondary sliding block, which is slidably disposed in the first mounting groove. The secondary sliding block is connected to a secondary hook rod, and the main sliding block and the secondary sliding block are connected by a connecting rod.

[0016] The main locking point includes a main locking hole on the frame, and the secondary locking point includes a secondary locking hole on the frame. The main hook rod passes through the main locking hole and is inserted into the frame, and the secondary hook rod passes through the secondary locking hole and is inserted into the frame. The frame is provided with a plurality of tensioning members, each corresponding to the main hook rod and the secondary hook rod. When the main hook rod and the secondary hook rod are inserted into the frame and lifted, the corresponding tensioning members pull the main hook rod and the secondary hook rod, causing the side frame to press against the frame.

[0017] By adopting the above technical solution, when the door leaf is closed, the main hook rod is inserted into the main lock hole, and the auxiliary hook rod is inserted into the auxiliary lock hole. The main hook rod and the auxiliary hook rod are directly opposite the corresponding tensioning member. Then, the shift fork lock is activated, which drives the main sliding block to move upward. The main sliding block drives the main hook rod to move upward, which drives the connecting rod to move. The connecting rod drives several auxiliary sliding blocks to move upward simultaneously, and the auxiliary sliding blocks drive the auxiliary hook rods to move upward. As the auxiliary sliding blocks and the main sliding blocks move upward, they gradually engage with the corresponding tensioning member. The tensioning member pulls the main hook rod and the auxiliary hook rod to make the side frame and the frame abut together, thereby locking the light fixture to the frame tightly.

[0018] Optionally, the tensioning component includes a tensioning block, which is slidably disposed within the frame and moves along the width direction of the frame. A first spring is disposed within the frame and connected to the tensioning block. The tensioning block has a guide groove and a fixing groove that communicate with each other. The main hook and the auxiliary hook are provided with guide surfaces, and both the main hook and the auxiliary hook are provided with insert blocks. When the main hook and the auxiliary hook are lifted, their respective guide surfaces abut against the corresponding tensioning block. Under the abutment of the guide surfaces, the tensioning block moves laterally and causes the ends of the main hook and the auxiliary hook to slide into the guide groove. When the ends of the main hook and the auxiliary hook are fully inserted into the corresponding guide groove, the insert blocks are inserted into the fixing groove.

[0019] By adopting the above technical solution, when the main hook and the auxiliary hook move upward, the guide surfaces of the main hook and the auxiliary hook abut against the corresponding tensioning blocks. As the main hook and the auxiliary hook gradually rise, the guide surfaces push the tensioning blocks to move in the direction closer to the light fixture. The ends of the main hook and the auxiliary hook gradually extend into the corresponding guide grooves and move relative to the corresponding guide grooves. When the ends of the main hook and the auxiliary hook are fully extended into the corresponding guide grooves, the insert block is fully inserted into the fixed groove. At this time, the lever is just moved to the highest point. The first spring is in a stretched state at this time. The first spring pulls the tensioning block, and the tensioning block pulls the insert block tightly, so that the main hook and the auxiliary hook pull the side frame tightly against the frame.

[0020] Optionally, the frame has a second sliding groove along its height direction, and an adjusting plate is slidably disposed in the second sliding groove. The adjusting plate has several oblong holes, and the adjusting plate is bolted to the frame through the oblong holes. The main locking hole and the secondary locking hole are opened on the adjusting hole. The top and bottom of the second sliding groove are sealed, and the sealing member abuts against the adjusting plate.

[0021] By adopting the above technical solution, the adjustment plate can slide in the second slide groove, thereby facilitating the adjustment of the height position of the main lock hole and the secondary lock hole, so that the main lock hole can be aligned with the main hook rod and the secondary lock hole can be aligned with the secondary hook rod, which facilitates installation and allows the main hook rod and the secondary hook rod to be smoothly inserted into the frame.

[0022] Optionally, the seal includes a second spring fixed inside the frame, the second spring being connected to a stop block, one end of the stop block extending out of the frame and abutting against the end of the adjusting plate.

[0023] By adopting the above technical solution, the adjusting plate is adjusted according to the positions of the main hook rod and the auxiliary hook rod. When the adjusting plate is adjusted upward, the stop block at the bottom of the second slide groove moves upward and presses against the bottom of the adjusting plate under the action of the second spring. The stop block at the top of the second slide groove is squeezed into the frame by the adjusting plate and the second spring at the top of the second slide groove is in a compressed state. When the adjusting plate is adjusted downward, the stop block at the bottom of the second slide groove extends into the frame, and the second spring at the top of the second slide groove drives the stop block of its connecting plate to press against the top of the adjusting plate, thereby achieving a seal on the second slide groove and preventing water and other impurities from flowing into the frame through the space between the adjusting plate and the second slide groove.

[0024] Optionally, the frame is provided with a second mounting groove, and a brush and a cushioning pad are provided in the second mounting groove.

[0025] By adopting the above technical solutions, the buffer pad can reduce the violent impact between the light fixture and the frame when it is closed, and the brush can prevent the light fixture from rubbing against the buffer pad and generating static electricity when it is closed, thus strengthening the protection of the light fixture and the frame.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When closing the sliding door, the light strip is spliced ​​with the frame. The fork lock is activated, which moves the main lock seat and several auxiliary lock seats. The main lock seat locks with the main locking point, and the auxiliary lock seats lock with their corresponding auxiliary locking points. The main lock seat and auxiliary lock seats work together to lock the light strip to the frame, so that the light strip and the frame are locked tightly at multiple points. This ensures that there are locking points at the top, bottom and middle of the door leaf, improving the sealing performance of the panoramic sliding door when locked.

[0028] 2. The adjusting plate can slide in the second slide groove, thereby facilitating the adjustment of the height position of the main lock hole and the secondary lock hole, so that the main lock hole can be aligned with the main hook rod and the secondary lock hole can be aligned with the secondary hook rod, which facilitates installation and allows the main hook rod and the secondary hook rod to be smoothly inserted into the frame.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0034] This application discloses a multi-point locking sliding door.

[0035] like Figure 1 , Figure 2 and Figure 3 The multi-point locking sliding door includes a light frame 1 and a frame 2. The light frame 1 includes a connecting frame 11, which is U-shaped. The glass of the sliding door is fixed on the connecting frame 11. Side frames 12 are snapped onto both sides of the connecting frame 11. Handles 13 are installed on both side frames 12. Two connecting sleeves 14 are fixed on the side of the connecting frame 11 away from the glass. One connecting sleeve 14 is located at the top of the connecting frame 11, and the other connecting sleeve 14 is located at the bottom of the connecting frame 11. Adjusting bolts 15 are threaded through the side frame 12, and two adjusting bolts 15 are threaded into one end of the connecting sleeve 14. A first sliding groove 16 and a first mounting groove 17 are formed on the side of the side frame 12 away from the connecting frame 11. The first sliding groove 16 communicates with the first mounting groove 17, and both the first sliding groove 16 and the first mounting groove 17 extend along the height direction of the side frame 12. A main lock seat 3 and several auxiliary lock seats 4 are inserted into the first mounting groove 17 and the first sliding groove 16. The main lock seat 3 is connected to its adjacent auxiliary lock seats 4, and adjacent auxiliary lock seats 4 are interconnected. Several auxiliary lock seats 4 are arranged along the height direction of the side frame 12 at the top, middle, and bottom. The main lock seat 3 is located at the center of the side frame 12. A shift fork lock 5 is installed on the side frame 12, and the shift fork lock 5 is connected to the main lock seat 3. The shift fork lock 5 is used to move the main lock seat 3 along the length direction of the first sliding groove 16.

[0036] The frame 2 is installed on one side of the doorway. A second sliding groove 21 and a second mounting groove 22 are provided on the frame 2, and the second sliding groove 21 and the second mounting groove 22 are connected. The second sliding groove 21 and the second mounting groove 22 are opened along the height direction of the frame 2. Brushes 23 and buffer pads 24 are provided on both sides of the second sliding groove 21 along its height direction. The buffer pads 24 are rubber pads. The brushes 23 are located between the side frame 12 and the buffer pads 24. An adjusting plate 6 is installed in the second mounting groove 22. The adjusting plate 6 is provided with a main locking point 7 and several auxiliary locking points 8. The main locking point 7 is located at the center of the adjusting plate 6, and the auxiliary locking points 8 are located at the top, middle, and bottom of the adjusting plate 6. The main lock seat 3 corresponds to the main locking point 7, and the auxiliary lock seat 4 corresponds one-to-one with the auxiliary locking points 8. Several oblong holes 61 are provided on the adjusting plate 6, and the adjusting plate 6 is bolted to the frame 2 through the oblong holes 61. Sealing elements 9 are fixed at the bottom and top of the second sliding groove 21, and the sealing elements 9 cooperate with the adjusting plate 6 to seal the second sliding groove 21.

[0037] When the sliding door is closed, the light fixture 1 is spliced ​​with the frame 2, and the lever lock 5 is activated. The lever lock 5 drives the main lock seat 3 and several auxiliary lock seats 4 to move. The main lock seat 3 locks with the main locking point 7, and the auxiliary lock seats 4 lock with their corresponding auxiliary locking points. The main lock seat 3 and the auxiliary lock seats 4 work together to lock the light fixture 1 and the frame 2 tightly, so that the light fixture 1 and the frame 2 are locked together at multiple points at the top, bottom and middle to form a tight fit. This ensures that there are locking points at the top, bottom and middle of the door leaf, which improves the sealing performance of the panoramic sliding door when locked.

[0038] When it is necessary to replace the main lock seat 3 and the auxiliary lock seat 4, only one side frame 12 needs to be removed to replace the main lock seat 3, the auxiliary lock seat 4 and the shift fork lock 5. There is no need to disassemble the entire sliding door, which makes replacement and maintenance convenient.

[0039] The adjusting plate 6 can slide within the second slide groove 21, thereby facilitating the adjustment of the height position of the main locking point 7 and the auxiliary locking point 8, so that the main locking seat 3 can be aligned with the main locking point 7 and the auxiliary locking seat 4 can be aligned with the auxiliary locking point 8, which facilitates the installation of the main locking point 7 and the auxiliary locking point 8.

[0040] The buffer pad 24 can reduce the violent impact between the light fixture 1 and the frame 2 when it is closed, and the brush 23 can prevent the light fixture 1 from rubbing against the buffer pad 24 and generating static electricity when it is closed, thus strengthening the protection of the light fixture 1 and the frame 2.

[0041] like Figure 1 , Figure 2 and Figure 3The shift fork lock 5 includes a sliding seat 51, which is installed on the side frame 12 facing the interior. The sliding seat 51 is bolted to the center of the side frame 12. A shift block 52 is slidably connected inside the sliding seat 51. A sliding damper 53 is attached to the sliding seat 51. The shift block 52 is in contact with the sliding damper 53. A connecting rod 54 is connected to the shift block 52. The connecting rod 54 passes through the side frame 12 facing the interior and is located between the two side frames 12.

[0042] The main lock seat 3 includes a main sliding block 31, which is a T-shaped block. The narrower end of the main sliding block 31 is slidably disposed in the first sliding groove 16 and connected to the connecting rod 54. The wider end of the main sliding block 31 is slidably disposed in the first mounting groove 17. The main sliding block 31 is connected to a main hook rod 32, which extends out from the first mounting groove 17.

[0043] The secondary lock seat 4 includes a secondary sliding block 41, which is a square block. The secondary sliding block 41 is slidably disposed in the first mounting groove 17. The secondary sliding block 41 is connected to a secondary hook rod 42, which extends out from the first mounting groove 17. The main sliding block 31 and the secondary sliding block 41 are connected by a connecting rod 18, and adjacent secondary sliding blocks 41 are connected to each other.

[0044] The main locking point 7 includes a main locking hole 71 on the adjusting plate 6, and the secondary locking point 8 includes a secondary locking hole 81 on the adjusting plate 6. The main hook rod 32 passes through the main locking hole 71 and is inserted into the frame 2, and the secondary hook rod 42 passes through the secondary locking hole 81 and is inserted into the frame 2. Several tensioning members 10 are provided in the frame 2, and the several tensioning members 10 correspond one-to-one with the main hook rod 32 and the several secondary hook rods 42.

[0045] The tensioning component 10 includes a tensioning block 101, which is slidably disposed within the frame 2. The tensioning block 101 moves along the width direction of the frame 2. A guide groove 102 and a fixing groove 103 are provided at the bottom of the tensioning block 101, and the guide groove 102 and the fixing groove 103 are connected. The ends of the main hook rod 32 and the auxiliary hook rod 42 that are inserted into the frame 2 are each provided with a guide surface 104, which is an inclined surface. A first spring 105 is provided on the tensioning block 101, and the first spring 105 is connected to the frame 2. Next, both the main hook rod 32 and the auxiliary hook rod 42 have a guide surface 104 at one end, and an insert block 106 is installed thereon. When the main hook rod 32 and the auxiliary hook rod 42 are lifted, their respective guide surfaces 104 abut against the corresponding tensioning blocks 101. Under the abutment action of the guide surfaces 104, the tensioning blocks 101 move laterally and cause the ends of the main hook rod 32 and the auxiliary hook rod 42 to slide into the guide grooves 102. When the ends of the main hook rod 32 and the auxiliary hook rod 42 are fully inserted into the corresponding guide grooves 102, the insert block 106 is inserted into the fixing groove 103.

[0046] The seal 9 includes a second spring 92. The second spring 92 is installed at both the top and bottom of the frame 2. The second spring 92 is connected to a stop 93. One end of the stop 93 extends into the frame 2, and the other end of the stop 93 extends out of the frame 2. The stop 93 abuts against the end of the adjusting plate 6.

[0047] During installation, the adjusting plate 6 is adjusted according to the positions of the main hook rod 32 and the auxiliary hook rod 42. When the adjusting plate 6 is adjusted upward, the stop block 93 at the bottom of the second slide groove 21 moves upward and presses against the bottom of the adjusting plate 6 under the action of the second spring 92. The stop block 93 at the top of the second slide groove 21 is squeezed into the frame 2 by the adjusting plate 6 and the second spring 92 at the top of the second slide groove 21 is in a compressed state. When the adjusting plate 6 is adjusted downward, the stop block 93 at the bottom of the second slide groove 21 extends into the frame 2, and the second spring 92 at the top of the second slide groove 21 drives its stop block 93 to press against the top of the adjusting plate 6, thereby sealing the second slide groove 21 and preventing water and other impurities from flowing into the frame 2 through the space between the adjusting plate 6 and the second slide groove 21.

[0048] When the door is closed, the main hook rod 32 is inserted into the main lock hole 71, and the auxiliary hook rod 42 is inserted into the auxiliary lock hole 81. The main hook rod 32 and the auxiliary hook rod 42 are directly opposite the corresponding tensioning blocks 101. Then, the lever 52 is turned, which causes the connecting rod 54 to lift. The connecting rod 54 causes the main sliding block 31 to move upward, which in turn causes the main hook rod 32 to move upward. The main sliding block 31 causes the connecting rod 18 to move, and the connecting rod 54 causes several auxiliary sliding blocks 41 to move upward simultaneously. The auxiliary sliding blocks 41 cause the auxiliary hook rod 42 to move upward. The auxiliary sliding blocks 41 and the main sliding block 31 move upward. When the main hook rod 32 and the auxiliary hook rod 42 move upward, their guide surfaces 104 abut against the corresponding tensioning blocks 101. As the main hook rod 32 and the auxiliary hook rod 42 gradually rise, the guide surface 104 pushes the tension block 101 to move along the direction closer to the light fixture 1. The ends of the main hook rod 32 and the auxiliary hook rod 42 gradually extend into the corresponding guide groove 102 and move relative to the corresponding guide groove 102. When the ends of the main hook rod 32 and the auxiliary hook rod 42 are fully extended into the corresponding guide groove 102, the insert block 106 is fully inserted into the fixing groove 103. At this time, the lever 52 is just turned to the highest point. The first spring 105 is in a stretched state at this time. The first spring 105 pulls the tension block 101, and the tension block 101 pulls the insert block 106 tightly, so that the main hook rod 32 and the auxiliary hook rod 42 pull the side frame 12 tightly against the frame 2.

[0049] The implementation principle of this application embodiment is as follows: When the sliding door is closed, the light fixture 1 is spliced ​​with the frame 2, and the fork lock 5 is activated. The fork lock 5 drives the main lock seat 3 and several auxiliary lock seats 4 to move. The main lock seat 3 locks with the main locking point 7, and the auxiliary lock seats 4 lock with the corresponding auxiliary locking points 8. The main lock seat 3 and the auxiliary lock seats 4 work together to lock the light fixture 1 and the frame 2, so that the light fixture 1 and the frame 2 are locked tightly at multiple points, so that there are locking points at the top, bottom and middle parts of the door leaf, which improves the sealing performance of the panoramic sliding door when locked.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
