Description

Technical Field

[0001] The utility model relates to the technical field of sliding door tracks, in particular to a hidden type sliding door linear upper track. Background Art

[0002] Sliding door tracks are components used to guide and support the movement of door panels in sliding door systems. They are usually installed above or below the door frame and are divided into hanging track and floor track types according to design and functional requirements. Hidden sliding door linear upper track belongs to the hanging track type sliding door, which hides the upper track in the wall or door frame, that is, the track cannot be seen from the outside.

[0003] However, it still has the following disadvantages in actual use:

[0004] After the track is installed, a cover plate needs to be fixed on the lower surface of the track to make the track more beautiful. Usually, the cover plate is fixed to the lower surface of the track with screws. Once the track needs to be repaired, the cover plate will be disassembled many times, and the screw holes will be slipped, causing the cover plate connection to be unstable. Changing the connection position will affect the appearance of the cover plate surface. Utility Model Content

[0035] See also Figure 1-5 As shown, this embodiment is a hidden sliding door linear upper track, comprising:

[0036] The main body assembly includes a double track 11 and a sealing plate 12;

[0037] There are three sealing plates 12, which are connected to both sides and the middle of the lower surface of the double track 11 respectively;

[0038] The double rails 11 play a supporting role, and the cover plate 12 plays a sealing and aesthetic role;

[0039] The locking assembly includes a mounting hole 20, a connecting column 21, a first groove 22, a spring 23, a supporting column 24, a supporting plate 25 and a rubber block 26;

[0040] The mounting holes 20 are evenly arranged on the sealing plate 12, the connecting column 21 is inserted into the mounting holes 20, the first groove 22 is arranged at the upper end of the connecting column 21, one end of the spring 23 is fixed to the inner bottom surface of the first groove 22, and the other end is fixed to the lower end of the supporting column 24, the supporting column 24 is movably connected in the first groove 22, the supporting plate 25 is hinged at the upper end of the supporting column 24, and the rubber block 26 is fixed to the end of the supporting plate 25 away from the supporting column 24;

[0041] The mounting hole 20 is used to mount the connecting column 21, which plays a supporting role. The first groove 22 provides a movable space for the supporting column 24. The spring 23 has a squeezing function. The supporting plate 25 plays a connecting role and can control the movement of the rubber block 26 to press against the double track 11.

[0042] There are two groups of support plates 25 and rubber blocks 26, which are symmetrically distributed on the upper end of the support column 24;

[0043] The main assembly also includes a wall 10, and a double track 11 is embedded and connected to the lower end of the wall 10 through expansion bolts;

[0044] The wall 10 plays a supporting role;

[0045] The main assembly also includes a pulley block 13 and a door leaf connector 14;

[0046] The pulley block 13 is slidably connected inside the double track 11, and the door leaf connector 14 is fixed below the pulley block 13;

[0047] The pulley block 13 facilitates the movement of the door leaf, and the door leaf connecting member 14 is used to connect the door leaves.

[0048] Working principle:

[0049] The connecting column 21 is inserted into the mounting hole 20. At this time, under the action of the spring 23, the supporting column 24 is in the upper section of the first groove 22, and the supporting plate 25 is in an inclined state;

[0050] Fix the double track 11 inside the wall 10 with expansion bolts, place the sealing plate 12 under the double track 11, press the connecting column 21 upward along the mounting hole 20, and drive the support column 24 to move upward. When it moves to the internal baffle of the double track 11, the support column 24 is pressed into the first groove 22, driving the support plate 25 to rotate and be in a horizontal state. At this time, the support plate 25 and the rubber block 26 are firmly pressed against the two side plates inside the double track 11.

[0051] This step facilitates fixing the cover plate 12 on the double track 11 , and does not require repeated drilling with screws, thereby reducing damage to the cover plate 12 and the double track 11 .

[0052] See also Figure 4-5 This embodiment is based on the above embodiment 1 and further includes:

[0053] A fixing assembly, the fixing assembly includes a second groove 30 and a waist-shaped through hole 31;

[0054] The second groove 30 is formed at the lower end of the connecting column 21, and the waist-shaped through hole 31 is formed at the top section of the second groove 30;

[0055] The second groove 30 plays a connecting role, and the waist-shaped through hole 31 plays a limiting role;

[0056] The fixing assembly also includes a T-shaped stud 32 and a telescopic block 33;

[0057] The T-shaped stud 32 is screwed into the second groove 30, and the telescopic block 33 is movably connected between the top section of the T-shaped stud 32 and the waist-shaped through hole 31;

[0058] The T-shaped stud 32 serves as a connection, and the telescopic block 33 serves as a limit.

[0059] Working principle:

[0060] When the support plate 25 and the rubber block 26 are firmly against the double track 11, the T-shaped stud 32 in the second groove 30 is rotated, and the telescopic block 33 is inserted into the waist-shaped through hole 31. At this time, the telescopic block 33 is located above the sealing plate 12, so that the connecting column 21 cannot move. If disassembly is required, the T-shaped stud 32 is rotated in the opposite direction to compress the telescopic block 33 to make it disengage from the waist-shaped through hole 31.

[0061] This step facilitates the fixing and disassembly of the connecting column 21 and allows the sealing plate 12 to be quickly removed.
