The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0035] Referring to Figures 1-5 The present application provides a side pressure pulley assembly convenient to install, which comprises a sliding seat 1 used for being mounted at the bottom of a door leaf and a pulley frame 7 used for being slidably arranged on a door frame rail and slidably matched with the sliding seat 1, two guide pulleys 9 are arranged on the pulley frame 7 at intervals; in addition, a sliding block 5 is slidably arranged on the sliding seat 1 and is drivingly matched with the pulley frame 7. Wherein, the sliding block 5 is used for being drivingly connected with a driving bar; when the driving bar is driven to slide to drive the sliding block 5 to slide on the sliding seat 1, the sliding seat 1 can be driven to sidewise move relative to the pulley frame 7 through the driving matching with the pulley frame 7, and then the door leaf is driven to move relative to the pulley frame 7.

[0036] In the present embodiment, the mounting groove 101 is formed in the sliding seat 1 and can be used for the sliding block 5 to slide therethrough.

[0037] The positioning clamp 10 is detachably arranged on the sliding seat 1 and abuts against the pulley frame 7, the positioning clamp 10 limits the sliding seat 1 in the initial position and limits the side displacement of the sliding seat 1 relative to the pulley frame 7, the positioning clamp 10 is arranged on the end of the sliding seat 1 away from the door leaf, and after the installation of the side pressure pulley assembly is completed, the positioning clamp 10 can be detached to release the limitation on the sliding seat 1.

[0038] Therefore, by arranging the detachable positioning clamp 10 on the end of the sliding seat 1 away from the door leaf, after the installation of the side pressure pulley assembly is completed, the positioning clamp 10 can be detached to release the limitation on the sliding seat 1, which is convenient to operate and has high reliability; in addition, since the positioning clamp 10 is not arranged between the door and window and the sliding seat 1, the installation precision of the side pressure pulley assembly is not affected.

[0039] In the embodiment, the top of the sliding seat 1 is connected with the bottom of the door and window, and the positioning clamp 10 is arranged on the bottom of the sliding seat 1.

[0040] It should be noted that in other embodiments, the positioning clamp 10 can also be detachably arranged on the pulley frame 7 and abut against the sliding seat 1 to limit the movement of the sliding seat 1, which can also achieve the same technical effect, and is not limited herein.

[0041] Referring to Figure 1 The sliding seat 1 is provided with two installation clamping holes 1031 for installing the positioning clamp 10, and the two installation clamping holes 1031 are arranged obliquely and spaced apart along the side displacement direction of the sliding seat 1.

[0042] Referring to Figure 1 and Figure 3 Specifically, the positioning clamp 10 includes a positioning ring 1001 and two elastic buckles 1002 arranged on the positioning ring 1001 and spaced apart, when the positioning clamp 10 is clamped in the installation clamping hole 1031 by the two elastic buckles 1002, the positioning ring 1001 abuts against the pulley frame 7. Preferably, the positioning ring 1001 and the two elastic buckles 1002 are integrally formed.

[0043] Therefore, the user can hook the positioning ring 1001 with his hand to insert or pull out the positioning clamp 10 from the installation clamping hole 1031, which is very convenient to operate.

[0044] Referring to Figures 1-5 again, the end of the sliding seat 1 away from the door leaf is provided with an installation cavity, and the pulley frame 7 is arranged on the installation cavity; in addition, the two slide rail plates 2 are arranged on the installation cavity and are symmetrically arranged front and back, and the first sliding groove which is in sliding cooperation with the sliding block 5 is formed between the two slide rail plates 2; the two slide rail plates 2 are made of stainless steel.

[0045] Thus, the slide rail plate 2 is made of stainless steel, when the sliding block 5 slides in the first sliding groove, the friction force is small, and the sliding is more smooth; at the same time, the wear of the sliding block 5 is small, thereby prolonging the service life.

[0046] Further, the sliding block 5 comprises a sliding block body 501 and a first wear-resistant sleeve 502 wrapped on the sliding block body 501, and the sliding block 5 is slidably connected with the first sliding groove through the first wear-resistant sleeve 502.

[0051] Thus, the sliding groove plate 3 is made of stainless steel, when the protrusion 7011 and the second sliding groove are relatively slid, the friction force is small, and the sliding is more smooth; at the same time, the wear of the protrusion 7011 is small, thereby prolonging the service life.

[0052] Further, further comprising two second wear-resistant sleeves 8 which are respectively wrapped on the two protrusions 7011, and the protrusion 7011 is slidably connected with the second sliding groove through the second wear-resistant sleeve 8. Preferably, the second wear-resistant sleeve 8 is a silica gel sleeve.

[0053] Therefore, by coating the second wear-resistant sleeve 8 on the convex strip 7011, when the second wear-resistant sleeve 8 is worn out, it can be directly replaced, so that the parts do not need to be replaced, thereby greatly reducing the cost.

[0054] Referring to Figures 1-5 Further comprising a driving shaft 4 penetrating through the sliding block 5, and the pulley frame 7 is provided with a curved slot, wherein one end of the driving shaft 4 is in driving connection with the transmission bar, and the other end of the driving shaft 4 extends into the curved slot and is in sliding fit with the curved slot; thus, when the sliding block 5 is moved on the sliding seat 1 by the transmission bar and the driving shaft 4, the sliding seat 1 can be driven to move laterally relative to the pulley frame 7 by the sliding fit of the driving shaft 4 and the curved slot. In addition, a shaft sleeve 6 is sleeved on the other end of the driving shaft 4, and the driving shaft 4 is in sliding fit with the curved slot through the shaft sleeve 6.

[0055] Specifically, the pulley frame 7 comprises a pulley frame body 701 and a cover plate 702 covering the pulley frame body 701, the cover plate 702 is provided with a guide hole 7021, the pulley frame body 701 is provided with an arc-shaped slot 7013 communicating with the guide hole 7021 and matching the shape of the guide hole 7021, and the guide hole 7021 and the arc-shaped slot 7013 communicate with each other to form a curved slot. Wherein, two convex strips 7011 are integrally formed on the left and right sides of the pulley frame body 701 respectively; the pulley frame body 701 is further provided with two convex columns 7012 spaced apart in the left-right direction, and two guide pulleys 9 are sleeved on the two convex columns 7012 respectively.
