Detailed Description

The present invention will be described in further detail with reference to the drawings and the following detailed description.

Referring to fig. 1 to 10, the present embodiment provides a sliding door 1 with a buffering function, which includes a door frame 13, a glass door 11, a spring member 16, a spring guide 15, a roller bracket 18, a roller 181, a wire chain 12, and a stopper 14, wherein a heating device is disposed in the glass door 11.

At least one glass 112 is mounted on the door frame 13, and a handle 111 is coupled to one side of the glass 112. In the present embodiment, the glass 112 has a double-layer structure. The glass 112 is coated with heating wires and configured to generate heat according to power application. The glass door 11 is configured to be slidable with respect to the door frame 13.

The door frame 13 is slidably coupled to the glass door 11 to support the glass door 11. The doorframe 13 is composed of side covers covering the upper and lower sides of the glass door 11 and both sides of the glass door 11, and the glass door 11 forms an integral rectangular frame. The door frame 13 is formed with a predetermined space portion therein to slidably couple the glass door 11.

The roller 181 is installed in the inner cavity of the top end of the door frame 13 and is in sliding connection with the top end of the inner cavity of the door frame 13, the top end of the glass door 11 is fixedly connected with the roller 181 through the roller bracket 18, and the stopper 14 is fixedly arranged on one side of the top end of the door frame 13.

The spring member 16 is vertically arranged in the side inner cavity of the door frame 13, the spring guide 15 is arranged at the side top end of the door frame 13, the bottom end of the spring member 16 is fixedly arranged at the side bottom end of the door frame 13, and the top end of the spring member 16 passes through the spring guide 15 to be connected with the roller 181.

Referring to fig. 5 and 6 in combination, one side of the wire chain 12 is connected to one side of the glass door 11, and the other side thereof is connected to the bottom end of the frame door frame 13. The inside of the wire chain 12 houses a wire for supplying power to the glass. The wire chain 12 is composed of a plurality of wire chain bodies 121 rotatably connected to each other. The wire chain bodies 121 are formed with spaces 123 through which the wires pass, and the plurality of wire chain bodies 121 are rotatably connected around the hinge shaft 122 at both sides.

When the glass door 11 slides, the wire chain 12 freely rotates between the chain bodies. Further, a part of one side of the wire chain 12 is connected to an upper side of the inner space of the door frame 13, and another part of the wire chain 12 is bent downward to the inner space of the doorway. A portion disposed under a portion of one side of the wire chain 12 is provided to be connected to one side of the glass door 11. That is, the wire chain 12 extends in the horizontal direction with the other side thereof fixed to the door frame 13 side in the longitudinal direction, bends downward, and extends in the horizontal direction to the glass door 11 side.

The turnbuckle 17 is connected to the spring member 16 at one side and to the door frame 13 at the other side. The turnbuckle 17 can adjust the tension of the spring member 16. Further, a plurality of turnbuckle 17 fastening holes are provided on the side cover side of the door frame 13 to be spaced at predetermined intervals in the vertical direction. The turnbuckle 17 is selectively coupled to a fastening hole of the turnbuckle to adjust the tension of the spring member 16.

Referring to fig. 7, more specifically, the turnbuckle 17 includes a turnbuckle body 171 and first and second links 172 and 173 screwed to both sides of the turnbuckle body. The first link 172 has a screw 1721 formed at one side thereof and a connection portion 1722 formed at the other side thereof for connection to the turnbuckle main body 171 and connected to one side of the door frame 13. In addition, the second link 173 is formed at one side with a screw thread 1731 for coupling with the turnbuckle body 171 and at the other side with a coupling part 1732 for coupling with the spring member 16.

With this configuration, the tension of the spring member 16 can be finely adjusted by the turnbuckle itself by adjusting the length of the turnbuckle by rotating the first link 172 or the second link 173. In addition, the tension of the spring member 16 can be adjusted to a relatively large width while moving the turnbuckle itself into the turnbuckle-fastening hole. Thus, the automatic closing speed of the glass door 11 can be adjusted.

Referring to fig. 8 to 10 in combination, the spring guide is assembled to an edge portion of the door frame 13 through which the spring member 16 passes, thereby preventing the spring member 16 from being separated. The spring guide 15 includes a guide bracket 151 and a guide roller 152. The guide bracket 151 is open on the lower side and is mounted inside the door frame 13. The guide bracket 151 is formed with rotation holes 1512 at both sides. The guide roller is provided with a rotation shaft rotatably connected to the rotation hole 1512 and connected to the guide bracket. On both sides of the guide bracket, fitting grooves 1511 for coupling with the door frame 13 are formed.

It is through being provided with spring unit 16, spring guide 15, gyro wheel support 18 and gyro wheel 181 that takes buffer function's push-and-pull door 1 in this scheme, glass door 11 passes through gyro wheel 181 and gyro wheel support 18 slidable mounting on door frame 13, make glass door 11 can slide along door frame 13, utilize spring unit 16 one end to link to each other with gyro wheel 181 simultaneously, its other end is then fixed in door frame 13 side bottom department, make glass door 11 at the closed in-process of moving along door frame 13, spring unit 16 can exert the effort of reseing to glass door 11, avoid glass door 11 because of the impact collision that the speed produced too fast in the closure process.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalent technologies, the present invention is also intended to include such modifications and variations.
