Description

Technical Field

[0001] The utility model relates to the technical field of rail-sliding door movement guide, in particular to an extremely narrow and silent upper rail movement guide structure. Background Art

[0002] The sliding door rail is installed on the wall. The existing sliding door rail structure is mostly a profile structure, and a guide bar is arranged inside it to cooperate with the slider to connect with the door frame 3 of the sliding door 4, so that the sliding door 4 can slide in a directional manner on the sliding door rail.

[0003] The slider matches the inner cavity of the sliding door rail, and the slider is embedded in the interior of the sliding door rail; the slider is connected to the top of the door frame 3. Although the door structure becomes narrower, the slider and the door frame 3 are connected in an embedded manner. The door frame 3 needs to be removed from the wall to remove the sliding door. The slider is on the side surface of the door frame 3, which increases the overall width of the door frame structure of the sliding door, limits the space required for door installation, and is prone to blockage and noise as the frequency of use increases.

[0004] Therefore, it is necessary to further improve the guiding structure of the existing door. Utility Model Content

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The utility model discloses an extremely narrow and silent upper rail moving guide structure, which comprises a door frame and a connecting seat detachably connected to the door frame; both sides of the connecting seat are connected with ball plungers.

[0008] Furthermore, the top surface of the door frame is provided with a top opening groove; the inner bottom wall of the door frame is provided with a convex strip; and two positioning grooves are formed between the two inner side walls of the door frame and the convex strip;

[0009] Extension parts are provided on both sides of the connecting seat; the thickness of the extension parts is equal to the thickness of the positioning groove, and the two extension parts are respectively inserted into the positioning grooves; a plunger hole matching the ball plunger is provided on the side surface of the extension part; a side opening groove is provided on the side surface of the door frame; the end of the ball plunger away from the ball passes through the side opening groove and is inserted into the plunger hole.

[0010] Furthermore, an inner thread post is arranged on the inner bottom wall of the door frame; a countersunk hole is opened on the top of the connecting seat; and a bolt is passed through the countersunk hole and then threadedly connected to the internal thread of the inner thread post.

[0011] Furthermore, the ball plunger is provided with a positioning retaining ring on the end face on one side of the ball; the positioning retaining ring is pressed tightly on the outer side wall of the door frame at a position directly facing the extension portion.

[0012] After adopting the above structure, the beneficial effects of the utility model are as follows: the utility model describes an extremely narrow and silent upper rail moving guide structure. When the utility model is used, the sliding door is fixed on the door frame, and the ball surfaces of the ball plungers on both sides are respectively attached to the left and right inner walls of the upper guide rail, and the door frame is directional sliding on the upper guide rail through the support of the balls; the noise generated by the sliding of the sliding door is reduced through the rolling connection between the balls and the upper guide rail, and the thickness extending out of the door frame is only a part of the balls, so that the thickness of the entire guide structure is narrower; a contact-type limit connection is adopted between the door frame and the upper guide rail, and the difficulty of disassembly and assembly is low.

[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 7 As shown, the utility model discloses an extremely narrow and silent upper rail moving guide structure, which comprises a door frame 3 and a connecting seat 5 detachably connected to the door frame 3; both sides of the connecting seat 5 are connected to ball plungers 2;

[0027] The buffer trigger rod 1 is fixed on the connecting seat 5, and the upper guide rail A is provided with a buffer body B used in conjunction with the buffer trigger rod 1; the ball plunger 2 has no essential difference from the prior art, so it is not described in detail; Figure 3 As shown, the ball can rotate freely inside the ball plunger 2;

[0028] The sliding door 4 is fixed on the door frame 3, and the ball surfaces of the ball plungers 2 on both sides are respectively attached to the left and right inner walls of the upper guide rail A, and the door frame 3 is directional slid on the upper guide rail A through the support of the balls; the noise generated by the sliding of the sliding door 4 is reduced through the rolling connection between the balls and the upper guide rail A, and the thickness of the sliding door 4 extending out of the door frame 3 is only a part of the balls, so that the thickness of the entire guide structure is narrower; the door frame 3 and the upper guide rail A adopt a contact-type limit connection, and the difficulty of disassembly and assembly is low.

[0029] As a preferred embodiment of the present invention, the top surface of the door frame 3 is provided with a top opening groove 301; the inner bottom wall of the door frame 3 is provided with a convex strip 304; two positioning grooves are formed between the two inner side walls of the door frame 3 and the convex strip 304;
