Description

Technical Field

[0001] This utility model belongs to the field of sliding door technology, specifically relating to a sliding door track locking device. Background Technology

[0002] The locking device in the frame of existing glass sliding doors is an important design feature to ensure the door is fixed and to enhance security and privacy, especially in scenarios such as balconies, bedrooms, or bathrooms. However, the lock on the frame of existing products is prone to accidental locking or damage to the lock. The lock groove on the frame affects the overall aesthetics. Furthermore, many sliding doors now do not require a frame, so they do not have a locking function. Utility Model Content

[0003] This addresses the technical problem that existing sliding door locking devices need to be installed on the frame, which can lead to accidental operation and affect aesthetics.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sliding door upper track locking device, comprising a door frame body, the door frame body including an upper track and a side frame, a locking device provided in the upper track, the locking device including a door lock slider, the door lock slider having a hollow sleeve, the sleeve having a locking rod, the locking rod having a locking part and an operating part at both ends respectively, the side wall of the side frame having a movable groove, the operating part of the locking rod being located in the movable groove and being able to move up and down.

[0005] Furthermore, the upper track is provided with an adjustment groove, and the two side walls of the adjustment groove are provided with raised positioning strips. The two side surfaces of the door lock slider are provided with recessed sliding grooves. The door lock slider is located in the adjustment groove, and the positioning strip is located in the sliding groove.

[0006] Furthermore, the locking bar is designed with an L-shaped structure.

[0007] Furthermore, the locking bar is a solid structure.

[0008] Furthermore, the main body of the door frame includes a left side frame, a right side frame, an upper track, and a lower track. The tops of the left side frame and the right side frame are connected by the upper track, and their bottoms are connected by the lower track to form the main body of the door frame.

[0009] Furthermore, locking devices are provided on both sides of the upper track, corresponding to the top of the left and right frames.

[0010] Furthermore, locking devices are provided on both sides of the lower track, corresponding to the bottom of the left and right frames.

[0011] This utility model has the following advantages: When the sliding door needs to be locked, pushing the operating part in the movable groove of the frame upwards causes the locking part at the top of the locking rod to engage with the corresponding locking hole on the outside, thus locking the sliding door. When the sliding door needs to be unlocked, pulling the operating part in the movable groove of the frame downwards causes the locking part at the top of the locking rod to disengage from the locking hole, allowing the sliding door to move left and right to open and close. By placing the locking device in the upper track, misoperation and damage to the lock are prevented. The door frame itself does not require a lock groove, resulting in a more aesthetically pleasing overall product. Attached Figure Description

Detailed Implementation

[0018] like Figures 1 to 5 As shown, a sliding door upper track locking device includes an aluminum profile door frame body 10 for mounting glass. The door frame body 10 includes an upper track 20 and a side frame 30. A locking device 40 is provided in the upper track 20. The locking device 40 includes a door lock slider 41. The door lock slider 41 has a hollow sleeve 42. The sleeve 42 has a solid L-shaped locking rod 43. The locking rod 43 has a locking part 44 and an operating part 45 at both ends. The side wall of the side frame 30 has a movable groove 31. The operating part 45 of the locking rod 43 is located in the movable groove 31 and can move up and down.

[0019] In practice, when the sliding door needs to be locked, the operating part 45 in the movable groove 31 of the frame 30 is pushed upward, and the locking part 44 at the top of the locking rod 43 falls into the corresponding external locking hole. At this time, the sliding door is locked. When the sliding door needs to be unlocked, the operating part 45 in the movable groove 31 of the frame 30 is pulled downward, and the locking part 44 at the top of the locking rod 43 leaves the locking hole. At this time, the sliding door can move left and right to open and close the door.

[0020] By placing the locking device 40 in the upper track 20, there will be no misoperation or damage to the lock. The door frame body 10 does not need to have a lock groove, making the product more aesthetically pleasing overall.

[0021] The upper track 20 is provided with an adjustment groove 201, and the two side walls of the adjustment groove 201 are provided with protruding positioning strips 202. The two side surfaces of the door lock slider 41 are provided with recessed sliding grooves 401. The door lock slider 41 is located in the adjustment groove 201 and the positioning strips 202 are located in the sliding grooves 401. In use, it is easier to slide the door lock slider 41 in the upper track 20 to adjust the lock gap.

[0022] The door frame body 10 includes a left side frame 11, a right side frame 12, an upper track 20, and the tops of the left side frame 11 and the right side frame 12 are connected by the upper track 20, and their bottoms are connected by the lower track 13 to form the door frame body 10.

[0023] The upper track 20 is equipped with locking devices 40 on both sides corresponding to the top of the left frame 11 and the right frame 12, and the lower track 13 is equipped with locking devices 40 on both sides corresponding to the bottom of the left frame 11 and the right frame 12.
