Description

Technical Field

[0001] The utility model relates to the technical field of barn doors, in particular to a heavy-duty guide rail barn door. Background Art

[0002] Heavy-duty guide rail barn doors are barn doors that use a heavy-duty guide rail system as support and sliding tracks. The door body is usually heavier and requires higher load-bearing capacity and stability. Heavy-duty guide rail barn doors are opened by pushing and pulling, do not take up additional space, and are suitable for small apartments or occasions with limited space, saving space.

[0003] Traditional doors may derail or bounce when impacted by external forces, affecting their stability. When they move to their extreme positions, they may collide with other objects, which can be dangerous and result in a poor user experience. Wooden doors can also corrode and become damaged if exposed to moisture for a long period of time.

[0004] In view of the above problems, the present utility model document proposes a heavy-duty guide rail barn door. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art that the door body may derail or jump when subjected to external force, collide with other objects when moved to the extreme position, and the log door body may be corroded and damaged due to long-term moisture. A heavy-duty guide rail barn door is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A heavy-duty guide rail barn door comprises two fixing frames, each of which is fixed to a wall by expansion bolts. A guide rail is fixedly connected between the two fixing frames, two rollers are slidably connected to the guide rail, clamping strips are respectively installed on both sides of the rollers, a door frame is installed between the plurality of clamping strips, and a door panel is installed in the door frame.

[0008] Two mounting holes are provided on one side of each of the clamping strips, and fixing wires are respectively provided in each of the mounting holes, and each of the fixing wires passes through the door frame;

[0009] One side of the clamping strips in the same group is respectively fixedly connected to a limiting block, and one side of the limiting block is fixedly connected to a silica gel block.

[0010] In a possible design, a mounting groove is provided on one side of the clamping bars of the same group, a screw is installed in the mounting groove, the screw is located below the guide rail, one end of the screw is threadedly connected to a nut, and a movable sleeve is provided on the circumference of the screw, and the movable sleeve is located between the two clamping bars.

[0011] In a possible design, a protrusion is provided in the middle of the roller, and a groove is provided on the upper surface of the guide rail, and the protrusion cooperates with the groove.

[0012] In a possible design, a center scale is installed in the middle of the door frame to ensure the stability of the door frame.

[0013] In a possible design, two obliquely arranged reinforcement plates are installed between the center scale and the door frame.

[0014] In a possible design, the surface of the door frame is coated with polyurethane waterproof coating.

[0015] In this application, when the barn door needs to be opened or closed, the roller slides on the guide rail through external force (such as manual pushing and pulling). The protrusion of the roller fits tightly with the groove of the guide rail to ensure a smooth sliding process.

[0016] The clamping bars are passed through the door frame and fastened by fixing wires to form a stable frame support structure. The rollers are installed between the clamping bars and move with the door frame.

[0017] When the door panel moves to the limit position of the guide rail, the silicone block on the limit block acts as a buffer to avoid damage and noise caused by direct impact.

[0018] The installation of center scales and reinforcement plates improves the overall stability and load-bearing capacity of the door frame, ensuring that the door panel remains stable during opening and closing.

[0019] The polyurethane waterproof coating on the surface of the door frame effectively prevents moisture penetration, protects the internal structure and materials from moisture, and extends the service life.

[0020] Beneficial effects:

[0021] In the present invention, the heavy-duty guide rail barn door is provided with clamping strips on both sides of the roller, and limit blocks and silicone blocks are installed on the clamping strips as buffer materials, thereby effectively reducing the impact force and noise of the door body when it is in the extreme position, thereby improving the user experience;

[0022] In the utility model, the heavy-duty guide rail barn door has a polyurethane waterproof coating coated on the surface of the door frame, which effectively prevents moisture penetration, protects the internal structure and materials from the influence of moisture, and reduces corrosion and damage problems caused by moisture.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1

[0030] Reference Figures 1-4 , a heavy-duty guide rail barn door, including: two sturdy fixing frames 1, use expansion bolts to firmly fix them to the wall, and ensure that the distance between the fixing frames 1 matches the designed guide rail 2 length.

[0031] Between the two fixing frames 1, a guide rail 2 is fixedly connected using bolts. The guide rail 2 should be made of high-strength material to withstand the weight of the door panel 4 and the friction during operation.

[0032] Two rollers 9 are slidably mounted on the guide rail 2 , ensuring that the protrusions 10 of the rollers 9 fit tightly with the grooves 7 of the guide rail 2 to achieve smooth sliding.

[0033] Clamping bars 8 are installed on both sides of the roller 9. The design of the clamping bars 8 should be able to fit tightly against the roller 9 and provide sufficient supporting force.

[0034] When installing the door frame 3 , multiple clamping strips 8 are passed through the mounting holes 15 and fixing wires 11 thereon and passed through the door frame 3 for fixing, ensuring that the door frame 3 is firmly connected to the frame composed of the rollers 9 and the clamping strips 8 .

[0035] A door panel 4 is installed inside the door frame 3 , and the thickness of the door panel 4 should be selected according to actual needs to ensure sufficient strength and durability.

[0036] A limit block 16 is installed on one side of the same group of clamping strips 8, and a silicone block 17 is fixed on the limit block 16. The silicone block 17 serves as a buffer material and can reduce impact force and noise when the door panel 4 moves to the limit position.

[0037] An installation groove 12 is provided between the clamping bars 8, a screw 13 is installed in the installation groove 12, and a movable sleeve 14 is sleeved on the circumference of the screw 13. The movable sleeve 14 is located below the guide rail 2 to facilitate limiting the roller 9 and ensure that the door body will not derail or jump during the sliding process.

[0038] The door frame 3 and door panel 4 are made of logs. The logs are split and dried to a moisture content of approximately 8° to 10°. They are then precision-cut, planed, and finely sanded to achieve a desired thickness, resulting in aesthetically pleasing surfaces. The grooves and holes are milled and formed using a CNC machining center, with pre-embedded screw holes for easy assembly and installation by the customer. This ensures a short production cycle, environmentally friendly efficiency, and convenient packaging and transportation.
