Description

Technical Field

[0001] The utility model relates to the technical field of screen window pulleys, in particular to a screen window pulley which can be stopped at will. Background Art

[0002] Windows are an important component of buildings. The setting of windows facilitates ventilation, air permeability, and light adjustment. Especially in the hot summer, opening windows regularly for ventilation is conducive to indoor air convection and plays a role in cooling down. In order to prevent mosquitoes from entering the room through the open windows or dust from entering the room. Screens are installed on the windows. In order to reduce the difficulty of moving the screens, pulleys are set at the bottom of the screens. The pulleys cooperate with the sliding grooves on the window frames and slide in the grooves to reduce friction.

[0003] A Chinese patent with publication number CN213654546U discloses a novel adjustable screen pulley, which can automatically adjust according to the state of the track in which the pulley is used, effectively avoiding the problem of the screen sliding and causing inconvenience, and improving the convenience of using the screen in conjunction with the track.

[0004] During use of the above-mentioned device, the pulley rolls and adjusts inside the track, and a tightening squeezing effect is achieved by turning the screws. However, long-term use may cause the screw connection to slip or loosen, which will make the subsequent squeezing not tight enough and affect the fixing effect. In addition, since the fixed position of the screen window cannot be adjusted arbitrarily, the practicality of the device will be reduced, which needs to be optimized and improved. Utility Model Content

[0009] The position adjustment component is arranged on both sides of the front and rear of the connecting support plate, and the top of the position adjustment component is fixedly connected with the top mounting component.

[0010] Preferably, the rolling adjustment assembly includes a detachable roller, and the detachable roller is rotatably connected to the middle of the front and rear walls of the rotating support frame, and the middle of the outer side of the detachable roller is connected to the pulley body.

[0011] Preferably, a fixing groove is formed on the outer wall of the pulley body, and a rubber strip is bonded inside the fixing groove.

[0012] Preferably, the position adjustment component includes a penetrating connecting rod, and the penetrating connecting rod passes through the front and rear ends of the inner part of the connecting support plate, and a buffer spring is sleeved on the outer top end of the penetrating connecting rod.

[0013] Preferably, the outer bottom end of the connecting rod is threadedly connected to a threaded adjustment cylinder, and a toggle block is welded to the bottom end of the threaded adjustment cylinder.

[0014] Preferably, the top mounting assembly comprises a sliding mounting block, and the sliding mounting block is fixedly connected to the top end of the connecting rod, and a fixing screw hole is formed on the top wall of the sliding mounting block.

[0015] Preferably, a docking groove is provided at the inner front end of the connecting support plate, and fastening screws are threadedly connected to the left sides of the front and rear ends of the connecting support plate, the rear end of the connecting support plate is integrally connected with a docking joint, and the rear end of the docking joint is clamped with an extended support plate.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model adjusts the position of the rotating support frame inside the clamping groove by adjusting the fixing screw.
