Description

Technical Field

[0001] The utility model relates to the technical field of sliding wheels, in particular to a sliding wheel for pulling an aluminum alloy door. Background Art

[0002] Aluminum alloy doors refer to doors made of aluminum alloy extruded profiles as frames, stiles and leaf materials. They are called aluminum alloy doors, or aluminum doors for short. Aluminum alloy doors and windows can increase indoor lighting and improve the overall appearance of the building. Aluminum alloy doors usually slide through pulleys.

[0003] Most of the existing aluminum alloy door pull pulleys are inconvenient to disassemble. Since the aluminum alloy door is located in the hanging rail, the pulley is easily deformed under the tension of its own weight over the years. It is inconvenient to replace the deformed pulley, which affects the service life. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above and / or existing problems in the pull-and-slide wheels of existing aluminum alloy doors, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a sliding wheel for pulling an aluminum alloy door. When the sliding wheel is damaged during use, the screw can be rotated to pull the first fixing frame to take out the sliding wheel for partial replacement. The remaining sliding wheels are still limited to the second boss to prevent the door from being displaced during the replacement process and causing injuries to people. The utility model solves the problem that most of the existing sliding wheels for pulling an aluminum alloy door are inconvenient to disassemble. Since the aluminum alloy door is located in a hanging rail, the sliding wheel is easily deformed under the pulling force of its own weight over the years, and it is inconvenient to replace the deformed sliding wheel, which affects the service life.

[0007] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0008] An aluminum alloy door pull-back wheel, comprising:

[0009] A hanging rail, wherein a plurality of first fixing frames are movably connected on both sides of the hanging rail, one end of the first fixing frame is movably connected to a sliding wheel, a second fixing frame is movably connected to the inside of the hanging rail, a door is fixedly connected to the bottom of the second fixing frame, a plurality of through grooves are provided on both sides of the hanging rail, a first groove is provided at the bottom of the through groove, a first boss is provided at the bottom of the first fixing frame, the first boss is located inside the first groove, a plurality of internal threaded holes are provided on both sides of the hanging rail, both ends of one side of the first fixing frame are movably connected with screws, one end of the screw passes through one side of the first fixing frame, and the external thread of the screw engages with the internal thread of the hanging rail.

[0010] As a preferred solution of the aluminum alloy door pulling sliding wheel described in the utility model, a second groove is arranged on the outer side of the sliding wheel, a second boss is arranged on the top of the second fixing frame, and both sides of the second boss are movably connected with multiple sliding wheels.

[0011] As a preferred solution for the aluminum alloy door pull-out wheel described in the utility model, a third boss is arranged on the top of the first fixed frame, a rotating shaft is fixedly connected between one side of the third boss and one side of the first boss, and the rotating shaft passes through the pull-out wheel.

[0012] As a preferred solution of the aluminum alloy door pulling slide wheel described in the utility model, a hollow layer is arranged inside the slide wheel, a fourth boss is arranged in the middle of the rotating shaft, and a plurality of first balls are movably connected between the outer side of the fourth boss and the inner side of the hollow layer.

[0013] As a preferred solution of the aluminum alloy door pull-back wheel described in the utility model, multiple second balls are movably connected inside both sides of the bottom of the hanging rail, and the second balls are slidably connected to both sides of the second fixing frame.

[0014] As a preferred solution of the pull-and-return wheel for an aluminum alloy door described in the utility model, fifth bosses are arranged on both sides of the top of the hanging rail, and a plurality of through holes are arranged on the top of the fifth bosses.

[0015] Compared with the prior art, the utility model has the beneficial effect that when the sliding wheel is damaged, the rotatable screw can pull the first fixing frame to remove the sliding wheel and perform partial replacement. The remaining sliding wheels still limit the second boss to prevent the door from being displaced during the replacement process and causing injuries to people. This solves the problem that most of the existing aluminum alloy door sliding wheels are inconvenient to disassemble. Since the aluminum alloy door is located in the hanging rail, the sliding wheel is prone to deformation under the pulling force of its own weight over the years, and it is inconvenient to replace the deformed sliding wheel, which affects the service life.
