Description

Technical Field

[0001] The utility model belongs to the field of sliding door buffer devices, and particularly relates to a hanging rail trigger. Background Art

[0002] Sliding doors are widely used in, for example, wardrobes, shower rooms, etc. To reduce the collision generated when the sliding door opens and closes, a buffer is usually installed above the sliding door, which cooperates with a trigger installed in the sliding door track. When the buffer collides with the trigger, the protruding trigger part on the trigger cooperates with the trigger part on the buffer to form a buffering effect. Traditional triggers are usually installed from the side of the sliding door track, so they must be constructed simultaneously with the sliding door track for assembly. If maintenance or replacement is required later, the entire sliding door track needs to be disassembled for reassembly, which brings inconvenience to installation.

[0003] In view of the above problems, the applicant has applied for a Chinese utility model patent with a patent number of "202322105190.0" and a name of "A quick-install trigger for hanging wheels". Its solution includes: a base, a rotary buckle rotatably arranged in the middle of the base, protruding trigger parts are arranged at both ends of the base, the rotary buckle is arranged in the middle of the base through a riveted bolt, and the rotation of the riveted bolt can drive the rotary buckle to rotate. The riveted bolt includes a bolt head and a bolt rod, a riveting part is arranged at the front end of the bolt rod, a square positioning part is arranged at the rear end, a square positioning hole adapted to the square positioning part is arranged at the center of the rotary buckle, and fastening screws are arranged on both sides of the base corresponding to the rotary buckle. The main remaining disadvantages are: 1. Since the rotary buckle is usually short, the contact surface with the sliding door track is small, resulting in poor clamping stability; 2. After the rotary buckle rotates in place, there is no positioning structure, which easily leads to improper adjustment or over-adjustment by the user. Content of the Utility Model

[0026] Refer to Figures 1-10As shown in the figure, the hanging rail trigger of the utility model includes a long strip-shaped main body 1 and a cover plate 2 covering the upper part of the long strip-shaped main body 1. The cover plate 2 is made of metal. Trigger parts 3 are integrally formed at both ends of the long strip-shaped main body 1. Symmetrical long strip-shaped telescopic buckles 4 are arranged on both sides of the middle part of the long strip-shaped main body 1, and a double-top cam 5 for driving the synchronous expansion and contraction of the long strip-shaped telescopic buckles 4 is arranged in the middle of the long strip-shaped main body 1 corresponding to the long strip-shaped telescopic buckles 4. An inner hexagonal nut 6 embedded in the long strip-shaped main body 1 is arranged at the lower end of the double-top cam 5. Inner hexagonal screws 7 for upward adjustment are arranged on both sides of the long strip-shaped main body 1 corresponding to the double-top cam 5, the upper ends of the inner hexagonal screws 7 are screwed to the cover plate 2, and tension springs 8 are arranged at both ends of the long strip-shaped telescopic buckles 4. Working principle and installation method: First, put this hanging rail trigger into the sliding door track, and then rotate the inner hexagonal nut 6 with a hexagonal wrench to drive the double-top cam 5 to rotate 180 degrees. The rotation of the double-top cam 5 drives the long strip-shaped telescopic buckles 4 to extend. Finally, rotate the inner hexagonal screw 7 with a hexagonal wrench so that it abuts against the sliding door track, and then the long strip-shaped telescopic buckles 4 can be driven to clamp on both sides of the sliding door track.

[0027] Preferably, a positioning concave point 9 is arranged in each of the four directions of left, right, up and down at the bottom of the long strip-shaped main body 1, and positioning convex points 10 are arranged below the two tops of the double-top cam 5. An arc-shaped concave surface 23 is arranged on the inner side of the long strip-shaped telescopic buckle 4, and arc-shaped convex surfaces 24 adapted to the arc-shaped concave surface 23 are arranged on the two tops of the double-top cam 5. Through the cooperation of the arc-shaped convex surface 24 and the arc-shaped concave surface 23, the rotation of the double-top cam 5 is made more stable. When the double-top cam 5 is in a horizontal state (retracted state), the positioning convex point 10 is positioned in the positioning concave point 9 in the left-right direction; when the double-top cam 5 is in a straight state (i.e., extended state), the positioning convex point 10 is positioned in the positioning concave point 9 in the up-down direction, and at the same time, the vertex of the arc-shaped convex surface 24 is positioned at the vertex of the arc-shaped concave surface 23 to ensure stability.

[0028] Preferably, positioning columns 11 are arranged on both sides of the long strip-shaped main body 1 corresponding to the double-top cam 5, and a first positioning groove 12 is arranged on one side of each of the two tops of the double-top cam 5. When the double-top cam 5 is in a horizontal state (retracted state), the first positioning groove 12 is positioned on the positioning column 11, so that the user cannot continue to rotate. And because of the positioning cooperation of the positioning convex point 10 and the positioning concave point 9, the user can hear the sound and the change of force during positioning, so the current state can be judged.

[0029] Preferably, the hexagon socket head cap nut 6 is integrally formed at the lower end of the double-top cam 5, and a rotating shaft 13 is integrally formed at the upper end of the double-top cam 5, and the cover plate 2 is connected through the rotating shaft 13. The double-top cam 5 structure formed integrally has the advantages of more stable structure and more convenient installation.

[0030] Preferably, sliders 14 are arranged on both sides of the long strip-shaped telescopic buckle 4, and sliding grooves 15 adapted to the sliders 14 are arranged on the cover plate 2. Through the cooperation of the sliders 14 and the sliding grooves 15, the sliding stability of the long strip-shaped telescopic buckle 4 is better.

[0031] Preferably, the cover plate 2 is fixed to the long strip-shaped main body 1 by rivets 16 at both ends, and riveting feet 17 and second positioning grooves 18 are integrally formed at both ends of the cover plate 2. Riveting grooves 19 adapted to the riveting feet 17 and positioning convex blocks 20 adapted to the second positioning grooves 18 are arranged on both sides of the long strip-shaped main body 1, and riveting posts 21 are further arranged at both ends of the long strip-shaped main body 1. Riveting holes 22 adapted to the riveting posts 21 are arranged on the cover plate 2. Through the above structure, the cover plate 2 can be firmly fixed above the long strip-shaped main body 1.

[0032] Preferably, a positioning convex rib 25 is arranged at the center of the arc-shaped concave surface 23 of the long strip-shaped telescopic buckle 4, and third positioning grooves 26 adapted to the positioning convex rib 25 are arranged at the two tops of the double-top cam 5. When the double-top cam 5 is in a straight state (i.e., the extended state), the positioning convex rib 25 is embedded in the third positioning groove 26 to further improve the stability of the double-top cam 5 after rotating in place.

[0033] Preferably, the positioning concave points 9 in the upper right direction at the bottom of the long strip-shaped main body 1 are connected by a first arc-shaped groove 27, and the positioning concave points 9 in the lower left direction at the bottom of the long strip-shaped main body 1 are connected by a second arc-shaped groove 28. A tapered surface 29 is formed at the intersection of the first arc-shaped groove 27, the second arc-shaped groove 28 and the positioning concave points 9. The cover plate 2 applies a force to the double-top cam 5. During adjustment: when the positioning convex point 10 of the double-top cam 5 rotates in the first arc-shaped groove 27 and the second arc-shaped groove 28, it is relatively easy and stable. When the positioning convex point 10 reaches the tapered surface 29 position, due to the action of the slope and pressure, the resistance will increase. When the user continues to rotate, after the positioning convex point 10 passes through the highest point of the tapered surface 29, the force will suddenly be released and the movement will accelerate. At this time, the user can more intuitively feel the change of the force and more clearly hear the sound during positioning, so it is easier to judge the current state.

[0034] Preferably, an elastic washer 30 is provided on the double top cam 5, and the cover plate 2 presses on the elastic washer 30. Since the elastic washer 30 has elasticity and is more easily compressed with better cushioning performance, after using the elastic washer 30, the double top cam 5 has a better feel during rotation, a more ideal positioning effect, and can prevent water.

[0035] As described above, there is no any form of restriction on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model.
