[0012] Preferably, the slider is made of stainless steel and the cross-sectional size of the slider is matched with the limiting hole.
[0013] Compared with the related art, the pulley structure on doors and windows proposed by the utility model has the following beneficial effects:
[0014] In the utility model, a door and window upper pulley structure is described, through the upper pulley mechanism provided, in which the bottom slide seat can slide inside the slide groove on the door and window frame, and the slide seat is pushed to the limiting hole on the side of the corresponding slide groove, and the sliding block on the side of the sliding seat can be inserted into the limiting hole by utilizing the rebound force of the spring, so that the positioning and installation work of the sliding seat on the door and window frame is realized. At the same time, a matching sticking plate is also provided on the outside of the limiting hole, and a permanent magnet is provided inside the rubber block on the inner side of the sticking plate. When the rubber block is inserted into the inner side of the limiting hole, the magnetic attraction of the permanent magnet acts on the sliding block, so that the sliding block can be adsorbed in the limiting hole even after losing the rebound force of the spring. On the inside, the installation stability of the entire upper pulley mechanism is improved, and it is also more convenient to replace the upper pulley mechanism later. Pull out the rubber block on the rear side of the sticking plate, and use the rod to insert into the limiting hole to abut the slider, so that the slider withdraws from the range of the limiting hole.

In addition, a convex silent sticking ring is provided on the side of the pulley, so that the pulley will not make abnormal noise when it contacts the side of the track. At the same time, a rubber ring is also provided on the outer ring of the pulley. The setting of the rubber ring gives the pulley better friction to prevent it from slipping, and it also has a silent effect. The design of the convex silent sticking ring and the rubber ring greatly enhances the silent effect of the pulley. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0021] Reference Figure 1-4 , please refer to Figure 1-Figure 4 ,in, Figure 1 This is a three-dimensional structural schematic diagram of a pulley structure on a door and window proposed by the utility model; Figure 2 This is a three-dimensional disassembled structural diagram of a pulley structure on a door and window proposed by the utility model; Figure 3 It is a three-dimensional disassembled schematic diagram of an upper pulley mechanism of an upper pulley structure for doors and windows proposed by the utility model; Figure 4 The schematic diagram of the internal cross-section structure of the plate of the upper pulley structure of a door and window proposed by the utility model. The upper pulley structure of a door and window comprises: a door and window frame 1, a slide groove 2 is provided on the upper side of the door and window frame 1, an upper pulley mechanism 3 is slidably arranged inside the slide groove 2, a limiting hole 6 is provided on the front side of the slide groove 2, and a plate 5 is arranged on the front side of the limiting hole 6.
[0022] In the present embodiment, the upper pulley mechanism 3 includes a slide seat 31, on which an axle seat 32 is fixedly mounted, a pulley 33 is rotatably mounted inside the axle seat 32, an annular groove 35 is provided inside the pulley 33, a rubber ring 37 is sleeved inside the annular groove 35, a convex sound-proof ring 34 is provided on the side of the pulley 33, an installation groove 39 is provided on the side of the slide seat 31, a slider 311 is slidably mounted inside the installation groove 39, a spring 310 is fixedly connected between the bottom of the slider 311 and the installation groove 39, the size of the slider 311 is adapted to the slide groove 2 and the slider 311 is slidably engaged on the inner side of the slide groove 2.
[0023] Through the above-mentioned arrangement, the convex edge silent ring 34 is arranged, so that when the pulley 33 slides in the track, the side of the pulley 33 contacts the track through the convex edge silent ring 34, and no noise is generated. In addition, a rubber ring 37 is sleeved and installed on the inner side of the ring groove 35. When the pulley 33 contacts the track, the rubber ring 37 directly contacts the track. The rubber material itself has a good silent effect. In addition, the rubber material has a good anti-skid ability. This arrangement makes the pulley 33 have a good silent effect when sliding inside the track, and at the same time it is not easy to slip between the pulley 33 and the track.
[0024] In this embodiment, a rubber block 51 is fixedly connected to the inner side of the attachment plate 5 , and a permanent magnet 52 is embedded in the inner side of the rubber block 51 .
[0025] By means of the above arrangement, the permanent magnet 52 is wrapped inside the rubber block 51 , so that the permanent magnet 52 is not easily damaged by collision.
[0026] In this embodiment, plugs 4 are inserted at both ends of the slide groove 2 .
[0027] Through the above-mentioned arrangement, the plug 4 is arranged on both sides of the slide groove 2 after the entire upper pulley mechanism 3 is installed, so that the entire door and window frame 1 looks more beautiful.
[0028] In this embodiment, the cross-sectional dimension of the rubber block 51 is slightly larger than the cross-sectional dimension of the limiting hole 6 .
[0029] By the above-mentioned arrangement, the cross-sectional dimension of the rubber block 51 is designed to be slightly larger than the cross-sectional dimension of the limiting hole 6, so that when the rubber block 51 is inserted into the limiting hole 6, the better rebound effect of the rubber block 51 is utilized to form an abutment effect between the inside of the rubber block 51 and the inner wall of the limiting hole 6, thereby preventing the rubber block 51 from slipping out of the limiting hole 6.
[0030] In this embodiment, a decorative arc edge is provided on the outer side of the pasting plate 5 .
[0031] By the above arrangement, the decorative arc edge opened on the outer side of the pasting plate 5 makes the entire outer side of the pasting plate 5 smoother and less abrupt, so that the pasting plate 5 can have an overall beautifying effect on the door and window frame 1 while covering the limiting hole 6.
[0032] In this embodiment, protrusions 36 are evenly distributed on the inner side of the annular groove 35 , and grooves 38 are evenly distributed on the inner ring of the rubber ring 37 , and the size of the grooves 38 is adapted to the protrusions 36 .
[0033] By the arrangement in the above manner, the protrusion 36 on the inner side of the annular groove 35 and the groove 38 on the inner ring of the rubber ring 37 are arranged so that when the rubber ring 37 is sleeved on the inner side of the annular groove 35, the groove 38 on the inner side of the rubber ring 37 is engaged with the protrusion 36 to achieve a clamping effect, so that relative sliding does not occur between the rubber ring 37 and the pulley 33.
[0034] In this embodiment, the slider 311 is made of stainless steel and the cross-sectional size of the slider 311 is matched with the limiting hole 6 .
[0035] By the above-mentioned arrangement, the slider 311 is made of stainless steel, so that a magnetic attraction can be generated between the slider 311 and the permanent magnet 52 on the inner side of the rubber block 51. When the slider 311 is inserted into the limiting hole 6 under the action of the rebound force of the spring 310, the rubber block 51 is inserted into the limiting hole 6 at this time, and the magnetic attraction between the permanent magnet 52 on the inner side of the rubber block 51 and the slider 311 is utilized to make the slider 311 more stable in the limiting hole 6. Even if the elastic force of the spring 310 is insufficient, the slider 311 can still be clamped in the limiting hole 6, thereby improving the stability of the clamping fixation of the slider 311.
[0036] The working principle of the pulley structure on doors and windows provided by the utility model is as follows:
[0037] When in use, slide the slide seat 31 into the slide groove 2 and slide it to align with the position of the limiting hole 6 on the side of the slide groove 2. Then, under the action of the rebound force of the spring 310, the slide block 311 is slidably inserted into the limiting hole 6. Subsequently, the rubber block 51 is inserted into the limiting hole 6 so that the bottom of the sticking plate 5 outside the rubber block 51 fits with the outer side of the door and window frame 1. At this time, a magnetic attraction is generated between the permanent magnet 52 and the slide block 311, so that the slide block 311 can be stably clamped in the limiting hole 6. After installation, the plug 4 is sealed in the slide groove 2. On both sides, in the working state, when the pulley 33 slides in the track, the side of the pulley 33 contacts the track through the convex edge silent ring 34, and no noise is generated. In addition, a rubber ring 37 is sleeved and installed on the inner side of the ring groove 35. When the pulley 33 contacts the track, the rubber ring 37 directly contacts the track. The rubber material itself has a good silent effect. In addition, the rubber material has a good anti-skid ability, so that the pulley 33 has a good silent effect when sliding inside the track, and at the same time it is not easy to slip between the track.
[0038] Compared with the related art, the pulley structure for doors and windows provided by the utility model has the following beneficial effects:
[0039] The utility model provides an upper pulley structure for doors and windows. The utility model utilizes a slider 311 in an upper pulley mechanism 3 to cooperate with a limiting hole 6 on a door and window frame 1. The upper pulley mechanism 3 can be installed and positioned directly by hand without the aid of tools, which is more convenient to use. In addition, the design of a convex silent ring 34 and a rubber ring 37 enhances the silent effect of the pulley 33.
