Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically a single-door locking structure applied to double doors. Background Technology

[0002] In modern architecture, double doors are widely used in various locations, such as commercial buildings and residences. Traditional double door locking structures have several drawbacks. On the one hand, common locks are mostly simple single-point locking mechanisms, offering poor security and difficulty in effectively resisting external damage. On the other hand, they also lack ease of use, failing to flexibly meet different opening needs.

[0003] For example, existing double doors often require both doors to be opened simultaneously, making it impossible to open only one. In daily use, this is inconvenient if only a small passage space is needed. Furthermore, existing locking structures typically use fixed-size bolts when locked, making it impossible to adjust the length of the bolt rod or the tightness of the bolt seat according to actual needs. This results in poor adaptability of the locks under different installation environments and usage conditions. Therefore, a single-door locking structure for double doors is needed to solve these problems. Utility Model Content

Detailed Implementation

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] like Figures 1 to 12As shown, a single-door locking structure for use in double doors includes a connecting strip 10 and a bolt seat 40. One end of the connecting strip 10 is connected to a bolt assembly 20 with an adjustable overall length. The bolt assembly 20 includes an adjustable connecting plate 21 with a movable bolt rod 22. The length direction of the adjustable connecting plate 21 is the same as the length direction of the bolt rod 22. An adjustment and fixing assembly is provided between the adjustable connecting plate 21 and the bolt rod 22 to adjust and fix the bolt rod 22 in a suitable position. The end of the connecting strip 10 away from the bolt assembly 20 is connected to a center latch. The length direction of the center-mounted one-way wrench 30 is parallel to the length direction of the pin rod 22. The center-mounted one-way wrench 30 is used to drive the connecting bar 10 and the pin assembly 20 to move. The pin seat 40 is used to limit the pin rod 22. The pin seat 40 includes a seat plate 41, a limiting groove 411 is provided on the seat plate 41, a seat plate 42 is connected to the seat plate 41, a limiting groove 421 is provided on the seat plate 42, and a seat plate fixing assembly is provided between the seat plate 41 and the seat plate 42. The seat plate fixing assembly is used to adjust the position of the seat plate 41 and connect the seat plate 41 and the seat plate 42.

[0034] The overall length of the pin assembly 20 can be adjusted by adjusting the position of the pin rod 22. The end of the pin rod 22 can be inserted into the gap formed by the first limiting groove 411 and the second limiting groove 421. The size of the gap formed by the first limiting groove 411 and the second limiting groove 421 can be adjusted by adjusting the relative position of the first adjusting plate 41 and the second adjusting plate 42, thereby adjusting the tightness of the pin seat 40 in fixing the pin rod 22.

[0035] In use, the center mullion one-way wrench 30 is installed on the vertical profile of one of the windows in a double-leaf window. The pin assembly 20 is connected to the center mullion one-way wrench 30 via the connecting strip 10. The pin seat 40 is installed on the horizontal profile of one of the windows in a double-leaf window, and the positions of the limiting groove 1 411 and the limiting groove 2 421 correspond to the positions of the pin rod 22. The installation and positional relationships between the center mullion one-way wrench 30, the pin assembly 20, the connecting strip 10, the pin seat 40, and the profile are as follows: Figure 1 As shown.

[0036] It should be noted that the pin 22 is composed of two plates connected together, with the two plates in a stepped shape, and the end dimensions of both plates are smaller than the main body dimensions, so that the end of the pin 22 can be inserted into the gap formed by the limiting groove 411 and the limiting groove 421.

[0037] like Figure 6-9The adjusting and fixing assembly includes multiple adjusting slots 221 formed on one side of the pin 22 and multiple adjusting strips 23 connected to the adjustable connecting plate 21. The multiple adjusting slots 221 are evenly distributed along the length of the pin 22, and the multiple adjusting strips 23 are evenly distributed along the length of the adjustable connecting plate 21. The adjusting strips 23 are engaged with the interior of the adjusting slots 221. Two silent rubber clips 24 are provided on the side of the pin 22 away from the adjusting slots 221, one of which is engaged with... A connecting plate fixing assembly is provided between the adjustable connecting plates 21. The connecting plate fixing assembly is used to fix the adjustable connecting plates 21. The connecting plate fixing assembly includes a countersunk waist hole 211 opened on the adjustable connecting plate 21 and a connecting threaded hole 241 opened in the middle of one side of the silent rubber buckle 24. The length direction of the countersunk waist hole 211 is parallel to the length direction of the adjustable connecting plate 21. A connecting bolt 25 is provided inside the countersunk waist hole 211. The connecting bolt 25 is threadedly connected to the connecting threaded hole 241.

[0038] When it is necessary to adjust the length of the pin assembly 20, first separate the connecting bolt 25 from the connecting threaded hole 241. At this time, the adjustable connecting plate 21 can be separated from the pin rod 22. Then, the adjusting clip 23 is inserted into the adjusting slot 221 and the adjustable connecting plate 21 is adjusted to a suitable position. At this time, the position of the connecting bolt 25 can be adjusted through the countersunk hole 211 and the position of the connecting bolt 25 corresponds to that of the connecting threaded hole 241. Then, the connecting bolt 25 is connected to the connecting threaded hole 241, thereby fixing the adjustable connecting plate 21 and completing the operation of adjusting the length of the pin assembly 20.

[0039] It should be noted that the length of the countersunk waist hole 211 is less than the length of the area formed by the multiple adjusting clips 23. This ensures that when the adjusting clips 23 are connected to the adjusting groove 221, the connecting bolt 25 can move inside the countersunk waist hole 211 and connect with the connecting threaded hole 241. This avoids the situation where the connecting bolt 25 cannot connect with the connecting threaded hole 241 after adjusting the position of the adjustable connecting plate 21.

[0040] like Figure 10-11The seat plate fixing assembly includes multiple adjusting slots 412 formed on the seat plate 41 and multiple adjusting strips 43 connected to the seat plate 42. The multiple adjusting slots 412 are evenly distributed along the width direction of the seat plate 41, and the multiple adjusting strips 43 are evenly distributed along the width direction of the seat plate 42. The adjusting strips 43 are engaged in the interior of the adjusting slots 412. A seat plate positioning assembly is provided between the seat plate 41 and the seat plate 42. The seat plate positioning assembly includes a connecting threaded hole 413 formed on the seat plate 41 and a countersunk hole 422 formed on the seat plate 42. A connecting bolt 44 is provided inside the countersunk hole 422, and the connecting bolt 44 is threadedly connected to the connecting threaded hole 413.

[0041] When it is necessary to adjust the overall width of the pin seat 40, the connecting bolt 44 is separated from the connecting threaded hole 413. At this time, the seat plate 41 and the seat plate 42 can be separated. The seat plate 42 is adjusted to a suitable position according to the actual situation during use, and the adjusting clip 43 is inserted into the adjusting groove 412. The connecting bolt 44 can then be moved along the countersunk hole 422 and the position of the connecting bolt 44 corresponds to that of the connecting threaded hole 413. Then, the connecting bolt 44 is connected to the connecting threaded hole 413, and the seat plate 42 is fixed, thus completing the operation of adjusting the overall width of the pin seat 40. For the seat plate 42 at different positions, the gap formed by the limiting groove 411 and the limiting groove 421 is different, thereby adjusting the tightness of fixing the pin rod 22.

[0042] like Figure 2-5 The center-mounted one-way wrench 30 includes a base 31, with a sliding rod 32 slidably connected inside the base 31. One end of the sliding rod 32 is connected to the connecting strip 10, and the other end of the sliding rod 32 is rotatably connected to multiple pressure rods 33. Each of the multiple pressure rods 33 has a pin hole 331 on one side. The end of the multiple pressure rods 33 away from the sliding rod 32 is rotatably connected to a handle 34. A cylindrical pin 35 is connected to the base 31, and the cylindrical pin 35 passes through the handle 34. The handle 34 is rotatably connected to the cylindrical pin 35. A spring plate 36 is provided inside the base 31. The spring plate 36 is located below the pressure rods 33 and the handle 34. The spring plate 36 is arc-shaped and is used to reset the pressure rods 33.

[0043] Under normal conditions, the latch 22 is inserted into the gap formed by the first limiting groove 411 and the second limiting groove 421, thereby fixing one window and allowing only one window to be opened at a time. When it is necessary to open the locked window, by turning the handle 34, the pressure rod 33 will drive the sliding rod 32 to move. As the sliding rod 32 moves, the connecting bar 10 drives the latch assembly 20 to move, causing the latch 22 to move out of the gap formed by the first limiting groove 411 and the second limiting groove 421, thereby releasing the fixing of the locked window and allowing it to be opened. The window is opened wider, and the cylindrical pin 35 is engaged in the pin hole 331, fixing the pressure rod 33 and the handle 34. At this time, the spring plate 36 is compressed. When the window needs to be locked again, the handle 34 can be rotated to make the pressure rod 33 rotate and move, so that the pin hole 331 is separated from the cylindrical pin 35. At this time, the pressure rod 33 and the slide rod 32 are reset under the reaction force of the spring plate 36. At this time, the pin rod 22 will be reset and inserted into the gap formed by the first limiting groove 411 and the second limiting groove 421, thereby re-fixing the window.

[0044] like Figure 8 and Figure 9 A snap fastener connector is provided between the silent snap fastener 24 and the pin 22. The snap fastener connector is used to install the snap fastener on the pin 22. The snap fastener connector includes a positioning slot 222 opened on one side of the pin 22. A positioning plate 26 is connected to the silent snap fastener 24. The positioning plate 26 is inserted into the positioning slot 222. The snap fastener connector also includes a storage groove opened on one side of the pin 22 and an elastic buckle 27 connected to the silent snap fastener 24. The end size of the elastic buckle 27 is larger than the body size of the elastic buckle 27. The elastic buckle 27 is elastic and can automatically reset. An elastic buckle groove 28 is opened on the inner wall of the storage groove. The elastic buckle 27 can be inserted into the elastic buckle groove 28.

[0045] When installing the silent rubber clip 24, the elastic clip 27 is deformed, and then the positioning plate 26 is inserted into the positioning slot 222. At this time, the elastic clip 27 will reset and be locked into the elastic clip groove 28, completing the installation of the silent rubber clip 24. This makes the installation of the silent rubber clip 24 relatively simple, and it is also easy to remove the silent rubber clip 24. When the silent rubber clip 24 is damaged, it is easy to replace it.
