Description

Technical Field

[0001] This utility model belongs to the field of thermally broken aluminum doors and windows technology, and in particular relates to thermally broken aluminum door and window pulley assemblies. Background Technology

[0002] The rollers for thermally broken aluminum doors and windows are key components that ensure smooth sliding of thermally broken aluminum doors and windows. Existing aluminum doors and windows are generally equipped with stainless steel rollers that slide between the rollers and the aluminum door frame.

[0003] Stainless steel pulleys and aluminum door frames may get stuck due to rust between the metal parts during long-term pushing and pulling, thus increasing the resistance to pushing and pulling. In order to improve the smoothness of pushing and pulling, we propose a thermally broken aluminum door and window pulley assembly that can be lubricated to solve the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a thermally broken aluminum door and window pulley assembly that allows for easy lubrication and improves the smoothness of pushing and pulling, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A thermally broken aluminum window and door pulley assembly includes a pulley set at the bottom of the aluminum window and door. Grooves are provided at both the top and bottom of the aluminum window and door. A connecting plate is detachably connected to the inner cavity of the groove. The connecting plate and the pulley are rotatably connected. An injection pipe is fixedly connected to the inner cavity of the groove and at the top of the pulley. A pipe hole is provided at the bottom of the injection pipe. A brush cloth is fixedly connected to the surface of the injection pipe away from the surface. A threaded cap is fixedly connected to one end face of the injection pipe. A threaded rod is threadedly connected to the axis of the threaded cap. A push plate is fixedly connected to the end face of the threaded rod inside the injection pipe. The push plate is slidably connected to the inner surface of the injection pipe. A vertical pipe is connected to the top of the injection pipe.

[0006] Preferably, the injection tube penetrates the connecting plate and extends to one end face of the connecting plate, and the injection tube has an internal hollow structure.

[0007] Preferably, there are multiple holes, which are evenly distributed at the bottom of the injection tube surface and located at the top of the pulley.

[0008] Preferably, the brush cloth is located on the side away from the injection tube, and the bottom end face of the brush cloth is in contact with the top of the pulley surface.

[0009] Preferably, the top of the vertical pipe is threaded with a pipe cap, and the vertical pipe is located at one end of the aluminum door / window.

[0010] The beneficial effects of this utility model are:

[0011] 1. When jamming or friction occurs, this utility model simply rotates the threaded rod, causing it to rotate on the inner surface of the threaded cap. This causes the push plate to slide on the inner surface of the injection tube, pulling the threaded rod out of the injection tube a certain distance. After pulling out a certain distance, lubricating oil enters the injection tube through the vertical pipe. Then, the threaded rod is rotated in the opposite direction, causing the push plate to push on the inner surface of the injection tube, pushing the lubricating oil out of the tube hole. After injection, the lubricating oil is finally applied to the pulley by brushing with a cloth under the push and pull of the pulley, thereby improving the smoothness of pushing and pulling.

[0012] 2. This utility model provides multiple pipe holes evenly spaced at the bottom of the injection pipe surface, with the pipe holes located at the top of the pulley, allowing lubricating oil to drip into the top of the pulley surface.

[0013] 3. This utility model sets the bottom end face of the brush to contact the top surface of the pulley, so that the lubricating oil that has been saturated on the pulley surface can be applied through the contact of the brush.

[0014] 4. This utility model has a pipe cap that is threaded to the top of the vertical pipe, which can seal the vertical pipe without injecting lubricating oil, thus preventing foreign matter from entering the vertical pipe. Attached Figure Description

[0022] In the following description, embodiments of the thermally broken aluminum window and door pulley assembly of this utility model will be described with reference to the accompanying drawings. Example 1

[0023] Figure 1-4This invention illustrates an embodiment of a thermally broken aluminum window and door pulley assembly, including a pulley 4 disposed at the bottom of an aluminum window and door 1. Grooves 2 are provided at both the top and bottom of the aluminum window and door 1. A connecting plate 3 is detachably connected to the inner cavity of the groove 2. The connecting plate 3 and the pulley 4 are rotatably connected. An injection pipe 5 is fixedly connected to the inner cavity of the groove 2, located at the top of the pulley 4. The injection pipe 5 penetrates the connecting plate 3 and extends to one end face of the connecting plate 3. The injection pipe 5 has an internal hollow structure, and a pipe hole 6 is provided at the bottom of the injection pipe 5. Multiple holes 6 are evenly distributed at the bottom of the surface of the injection tube 5, and the holes 6 are located at the top of the pulley 4. This arrangement allows lubricating oil to drip onto the top surface of the pulley 4. A brush 7 is fixedly connected to the surface of the injection tube 5 away from the injection tube 5. The brush 7 is located on the side away from the injection tube 5, and its bottom end face contacts the top surface of the pulley 4. The top contact of the surface allows the lubricating oil that has been saturated on the surface of the pulley 4 to be applied by the brush 7. A threaded cap 8 is fixedly connected to one end of the injection tube 5, and a threaded rod 9 is threadedly connected to the axis of the threaded cap 8. A pusher plate 10 is fixedly connected to the end face of the threaded rod 9 inside the injection tube 5. The pusher plate 10 is slidably connected to the inner surface of the injection tube 5. A vertical pipe 11 is connected to the top of the injection tube 5. When jamming or friction occurs, simply rotate the threaded rod 9 so that the threaded rod 9 is on the inner surface of the threaded cap 8. The threaded rod rotates, causing the pusher plate 10 to slide on the inner surface of the injection tube 5, pulling the threaded rod 9 out of the injection tube 5 a certain distance. After being pulled out a certain distance, the lubricating oil enters the interior of the injection tube 5 through the vertical pipe 11, and the threaded rod 9 rotates in the opposite direction, causing the pusher plate 10 to push on the inner surface of the injection tube 5, pushing the lubricating oil out of the pipe hole 6. After the injection is completed, the lubricating oil is finally applied to the pulley 4 by the brush cloth 7 under the push and pull of the pulley 4, thereby improving the smoothness of the push and pull. Example 2

[0024] Figure 1-4This invention illustrates an embodiment of a thermally broken aluminum window and door pulley assembly, including a pulley 4 disposed at the bottom of an aluminum window and door 1. Grooves 2 are provided at both the top and bottom of the aluminum window and door 1. A connecting plate 3 is detachably connected to the inner cavity of the groove 2, and the connecting plate 3 and the pulley 4 are rotatably connected. An injection pipe 5 is fixedly connected to the inner cavity of the groove 2, located at the top of the pulley 4. A pipe hole 6 is provided at the bottom of the injection pipe 5. A brush cloth 7 is fixedly connected to the surface of the injection pipe 5 away from its outer surface. One end face of the injection pipe 5 is fixedly connected to... A threaded cap 8 is threadedly connected to a threaded rod 9 at its axial center. A pusher plate 10 is fixedly connected to the end face of the threaded rod 9 inside the injection tube 5. The pusher plate 10 is slidably connected to the inner surface of the injection tube 5. A vertical tube 11 is connected to the top of the injection tube 5. A tube cap is threadedly connected to the top of the vertical tube 11. The vertical tube 11 is located at one end face of the aluminum door and window 1. By setting a tube cap threadedly connected to the top of the vertical tube 11, the vertical tube 11 can be tightly covered when no lubricating oil is injected, preventing foreign matter from entering the vertical tube 11.

[0025] Working principle: When this utility model is in use, if jamming or friction occurs, simply rotate the threaded rod 9 so that the threaded rod 9 rotates on the inner surface of the threaded cover 8, thereby driving the push plate 10 to slide on the inner surface of the injection tube 5, so that the threaded rod 9 pulls out of the injection tube 5 a certain distance. After pulling out a certain distance, the lubricating oil enters the interior of the injection tube 5 through the vertical pipe 11, and the threaded rod 9 is rotated in the opposite direction, so that the push plate 10 pushes on the inner surface of the injection tube 5, pushing the lubricating oil out of the pipe hole 6. After the injection is completed, the lubricating oil is finally applied to the pulley 4 by the brush cloth 7 under the push and pull of the pulley 4, thereby improving the smoothness of the push and pull.
