As shown in fig. 1 and 2, the fixing member 100 includes a lateral horizontal support bar 101 for fixing to the furniture body 300, a support bar 102 extending along the lateral horizontal support bar 101, and a guide rail bar 103 provided on the support bar 102.

The lateral horizontal support rods 101 and the support bars 102 are of an integrated structure made of aluminum alloy materials, the lateral horizontal support rods 101 are hollow tubular, the upper surfaces and one side surfaces of the lateral horizontal support rods are mutually perpendicular planes, and the rest circumferential surfaces are round surfaces. With a circular aperture 107 therethrough.

Referring to fig. 2 and 5, the furniture body 300 includes plug connectors at two ends of the lateral horizontal support rod 101, and the plug connectors have plugs with shapes and sizes matched with those of the pipe holes 107, and the lateral horizontal support rod 101 is inserted into the plugs to realize connection with the furniture body 300.

The lateral horizontal support bar 101 has a planar side surface facing the inside of the furniture body 300, and the support bar 102 is integrally provided on the side surface of the lateral horizontal support bar 101. The brace bar 102 has a T-shaped cross section and includes a connecting portion 104 extending horizontally from the side surface of the lateral horizontal support bar 101 toward the inside of the furniture body 300, and a mounting portion 105 connected to an outer end of the connecting portion 104. The mounting portion 105 extends vertically, and thus the upper and lower surfaces of the mounting portion 105 protrude from the surface of the connecting portion 104, thereby forming the T-shaped structure.

Grooves 106 are respectively formed on the upper and lower surfaces of the mounting portion 105, and the rail bars 103 are half-buried and fixed in the grooves 106 by welding. The longitudinal section of the guide rail bar 103 is circular to ensure sufficient strength and service life.

As shown in fig. 1 and 3, the sliding member 200 includes a pulley seat 201 made of an aluminum alloy material and a plurality of pulleys 202 disposed in the pulley seat 201.

The pulley seat 201 is integrally connected with the movable part 400, a pulley cavity 203 with a rectangular cross section is arranged in the pulley seat 201, a slotted groove 204 communicated with the pulley cavity 203 is arranged on one side, facing the supporting strip 102, of the pulley seat 201, and the pulleys 202 are installed in the pulley cavity 203 through a pulley shaft 205 and are respectively arranged at the upper position and the lower position of the slotted groove 204.

When the pulley 202 is installed, the pulley shaft 205 extends into the pulley cavity 203 from the opening 206 at the side of the pulley seat 201 slot 204, passes through the pulley 202 preset in the pulley cavity 203, and then extends into the blind hole 207 on the inner wall of the pulley cavity 203 corresponding to the opening 206, so that the installation of the pulley 202 can be realized.

Referring to fig. 1 to 3, when the pull rail pulley structure is used, the lateral horizontal support rod 101 is fixed to the furniture body 300, the pulley seat 201 is inserted into the support bar 102 from one end thereof, the support bar 102 passes through the slot 204 of the pulley seat 201 and extends into the pulley cavity 203, and the guide rail 103 of the support bar 102 is in fit contact with the pulley 202 of the pulley seat 201. The slider 200 can slide smoothly relative to the stator 100 by the engaging operation of the pulley 202 and the rail bar 103.

In order to further improve the use experience, the width of the slot 204 on the pulley seat 201 is slightly larger than the thickness of the connecting portion 104 in the supporting bar 102, so that when the sliding member 200 slides relative to the fixing member 100, the pulley seat 201 does not contact with the supporting bar 102, and unnecessary sliding friction is not generated, so that the sliding member 200 runs more smoothly.

In order to further improve the reliability, an arc concave surface 208 which is in matched contact with the guide rail strip 103 is arranged on the circumferential surface of the pulley 202, and the arc concave surface 208 plays a role in limiting the pulley 202, so that the pulley 202 is prevented from moving left and right relative to the guide rail strip 103, and the probability that the pulley 202 is separated from the guide rail strip 103 is reduced.

In order to avoid damage to the product caused by improper installation, the corners of the support bar 102 and the pulley cavity 203 are rounded and chamfered to avoid scraping or scratching during installation.

Fig. 4 shows a schematic view of the drawer in which the drawer rail pulley structure is applied to a drawer, in which a fixed member 100 is coupled to a furniture main body 300, and a sliding member 200 is integrally provided on an outer lower side of a drawer wall 401 made of an aluminum alloy material. A step 402 is provided below the inner side of the drawer wall 401, and a drawer bottom 403 is mounted on the step 402.

The sliding parts 200 on the drawer wall plates 401 at two sides are matched and sleeved on the fixing part 100, and the drawing function of the drawer is realized through the matching action of the sliding parts 200 and the fixing part 100.

Besides the drawer structure, the sliding rail pulley structure can be applied to other movable parts within the scope of the skilled person, for example, to a movable laminate, and the sliding member is integrally arranged on two sides of the aluminum alloy movable laminate, and the sliding member is matched with a fixing member arranged on the furniture body, so that the movable laminate can be pulled and slid.

This pull track pulley structure's main advantage lies in: the fixed member is integrated with the furniture body, both as a guide for the slider and as part of the furniture body support structure. Similarly, the sliding part is integrated with movable parts such as a drawer, a movable laminate and the like made of aluminum alloy, is a part of the movable parts, and simultaneously plays a role of a sliding rail. By adopting the pull rail pulley structure, the installation structure of the movable parts such as the drawer and the movable laminate is more concise, and meanwhile, the sliding rail is not required to be additionally installed, so that the movable parts such as the drawer and the movable laminate can be conveniently integrated into the aluminum alloy furniture, and the defects in the prior art are overcome.
