Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically a clampable pulley. Background Technology

[0002] The main functions of door and window fitting pulleys include saving effort, reducing friction loss, and ensuring the stability and smoothness of the pushing and pulling process. By reducing the direct friction between the door and window sash and the track, the pulley makes the pushing and pulling process more effortless, while also reducing the wear and tear on the doors and windows and extending their service life.

[0003] Currently used pulleys have a simple structure and need to be fixed by nailing. However, the structure itself has limited support strength, which can easily lead to the pulleys loosening or even falling off after long-term use, affecting the sliding performance.

[0004] Therefore, a novel clampable pulley is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clampable pulley to solve the problems mentioned in the background art, such as the pulley's simple structure requiring nailing for fixation, and the limited support of the structure itself, which can easily lead to the pulley loosening or even falling off after long-term use, affecting the sliding performance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clampable pulley, comprising an inner shell, a first connecting seat being fitted to the left side of the inner shell, a second connecting seat being fixedly connected to the right side of the inner shell, and a strong supporting stabilizing component being provided inside the inner shell.

[0007] The stabilizing component includes a steel plate. The front and rear ends of the inner shell are hollowed out. Sockets are sleeved on both sides of the front end of the inner shell. Two sets of steel plates are provided and vertically penetrate the interior of both sides of the inner shell. The sockets are sleeved on the outside of the front end of the steel plate. Fixing bolts are installed through the interior of the sockets, and the rear ends of the fixing bolts penetrate the interior of the steel plate. Four sets of pulleys are provided inside the inner shell. A rotating shaft is installed through the interior of the pulleys. The two ends of the rotating shaft penetrate the two ends of the inner shell respectively, and an auxiliary circular frame is slidably sleeved on the outside of the outer end of the rotating shaft.

[0008] As a further technical solution of this utility model, multiple sets of inner seats are fixedly connected to the top and bottom of the outer shell. The inner seats are sleeved and fixed to the outside of both ends of the auxiliary round frame. Connecting frames are horizontally fixed between each pair of auxiliary round frames.

[0009] As a further technical solution of this utility model, a clamping piece is vertically fixedly connected to the bottom of the first connecting seat, and a fastening bolt is horizontally inserted through the inside of the clamping piece. The outer side of the fastening bolt penetrates through the left side of the first connecting seat and is fixedly connected to a knob. The other side of the fastening bolt penetrates through the left side of the inner shell.

[0010] As a further technical solution of this utility model, the inner shell has two vertically fixed rods on both sides, and a brush is fixedly sleeved on the outside of the fixed rods. The inner shell has two sets of fixed plates on both sides, and the inner shell has two sets of right-angle brackets on both sides of the top and bottom ends.

[0011] As a further technical solution of this utility model, the inner side of the right-angle frame is fixedly connected to the outer side of the fixing plate, and the two sets of fixing plates are respectively located on both sides of the brush.

[0012] As a further technical solution of this utility model, sound insulation plates are horizontally arranged at the top and bottom of the inner shell. Through slots are equally spaced inside the sound insulation plates. The through slots are sleeved on the outside of the rotating shaft. Uprights are fixedly connected to both sides of the top and bottom of the inner shell.

[0013] As a further technical solution of this utility model, the sound insulation board has through holes on both sides, and an installation collar is provided through the inside of the installation hole, and the outside of the installation collar is sleeved on the outside of the upright.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the clampable pulley not only achieves strong support and stability, but also noise reduction.

[0015] (1) By setting steel plates, sockets, fixing bolts, fastening bolts, first connecting seats, clamps, rotating shafts, auxiliary round frames and connecting frames, the first connecting seats are attached to the left side of the inner shell. The fastening bolts are used to move through the inside of the clamps and the side wall of the inner shell to effectively fix the overall structure and ensure that the first connecting seats will not fall off during use, thus strengthening the connection force between the structures. By adding two sets of steel plates that penetrate through the inside of both sides of the inner shell, high load-bearing capacity is achieved, ensuring the overall robustness and stability of the inner shell. The auxiliary round frame is slidably sleeved on the outside of the rotating shaft, which plays a role in limiting the sliding of the two ends of the rotating shaft, preventing the pulley from shifting and not affecting the normal use of the pulley. Multiple sets of inner connecting seats are sleeved and fixed on the outside of the auxiliary round frame to ensure the stability of the limiting structure.

[0016] (2) By setting up a brush, a fixing rod, a fixing plate and a right angle bracket, two sets of fixing plates are located on both sides of the brush to limit and protect the brush. Multiple sets of right angle brackets provide strong support to the outside of the fixing plate to ensure the stability of the fixing plate itself and prevent the fixing plate from tilting outward. The brush can be used to clean the inside of the track to ensure the smooth use of the pulley.

[0017] (3) By setting up sound insulation panels, uprights, mounting holes and mounting rings, the two sets of sound insulation panels are located at both ends inside the inner shell, which can effectively reduce noise and isolate noise transmission during the operation of the pulley, and optimize the use environment. The two sides of the mounting rings are respectively fitted into the mounting holes and uprights to improve the balance of the sound insulation panels themselves. By opening through slots, it is convenient for the shaft to pass through and install. Attached Figure Description
