Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, in particular to a side pressure pulley assembly and a push-pull side pressure pulley group having the same. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Doors and windows can be opened and closed in various ways, such as push-pull, casement, and lift. In the case of push-pull doors and windows, due to the limitation of their own sliding structure, their sealing performance is poor, and it is difficult to meet the requirements of some environments with high usage requirements. For this reason, some push-pull doors and windows that can achieve side pressure sealing have appeared on the market. After sliding and closing, such doors and windows can be driven to gradually move sideways toward the door frame by turning the handle, and the sealing strips on the doors and windows are pressed tightly against the door frame, thereby improving the sealing performance of the doors and windows when they are closed.

[0004] In order to achieve the lateral movement of doors and windows, it is necessary to install a side pressure pulley assembly at the bottom of the doors and windows. To this end, Patent No. 202330738905.9 discloses a push-pull side pressure pulley, which includes a sliding seat for installation at the bottom of the door leaf, a pulley frame slidingly matched with the sliding seat, and a guide pulley arranged on the pulley frame, such as Figure 1 As shown. The pulley frame is provided with a guide groove, which is used to slide and engage with a block on a transmission bar, and the transmission bar is connected to the handle. Therefore, when the handle is rotated, the transmission bar can be driven to slide, and the sliding seat and the pulley frame can be driven to move relative to each other through the sliding engagement of the guide groove and the block.

[0005] However, in actual use, it was found that since the pulley frame directly cooperates with the transmission bar, and the transmission bar will shake when sliding on the door and window slide groove (the processing accuracy of the door and window slide groove is low), the pulley frame will also shake, and then the sliding seat and the doors and windows set on the sliding seat will also shake. Not only can the sealing of the doors and windows when closed be unable to be guaranteed, but a lot of noise is also generated, reducing the user experience. Utility Model Content

[0006] In order to overcome the defects of the prior art described above, the utility model provides a side pressure pulley assembly and a push-pull side pressure pulley group having the same, so as to solve the problem of the pulley frame shaking mentioned in the background technology above.

[0013] Furthermore, a second sliding groove is provided on the sliding seat, and a convex strip which is slidably matched with the second sliding groove is provided on the pulley frame.

[0014] Furthermore, it also includes a wear-resistant sleeve sleeved on the convex strip, and the wear-resistant sleeve is in sliding contact with the second sliding groove.

[0015] Furthermore, it also includes a driving shaft passing through the sliding block, and the pulley frame is provided with a guide groove for one end of the driving shaft to extend into and engage with each other for sliding cooperation;

[0016] When the sliding block is driven to slide on the first sliding groove, the sliding seat and the pulley frame can be relatively laterally displaced through the clamping and sliding cooperation between the driving shaft and the guide groove.

[0017] Furthermore, it also includes a sleeve sleeved on one end of the driving shaft, and the sleeve is in sliding contact with the guide groove.

[0018] Furthermore, the pulley frame includes a pulley frame body and a cover plate covered on the pulley frame body, the cover plate is provided with a guide hole, the pulley frame body is provided with a groove connected to the guide hole and adapted to its shape, the guide hole cooperates with the groove to form the guide groove.

[0019] Furthermore, the pulley frame body is provided with an avoidance hole connected to the groove, and the shaft sleeve can pass through the avoidance hole and be sleeved on the driving shaft.

[0020] Furthermore, a blocking cover is included, and the blocking cover is arranged on the avoidance hole to achieve sealing.

[0021] Furthermore, it also includes a positioning member detachably arranged on the pulley frame, and the positioning member is used to cooperate with the pulley frame to achieve initial positioning of the pulley frame.

[0022] In addition, the utility model also provides a push-pull side pressure pulley assembly, comprising the above-mentioned side pressure pulley assembly and a push-pull pulley assembly arranged on the side pressure pulley assembly.

[0023] To sum up, the utility model provides a side pressure pulley assembly and a push-pull side pressure pulley group having the same, which transmits the movement by arranging a slider between the transmission bar and the pulley frame, and a first slide groove for sliding the slider is provided on the sliding seat. Since the processing accuracy of the first slide groove can be guaranteed, it can be ensured that the slider does not shake when sliding on the first slide groove, thereby avoiding shaking of the pulley frame that transmits the movement with it, and further avoiding shaking of the sliding seat and the door leaf; therefore, the side pressure pulley assembly of the present application can not only ensure the sealing of the door leaf when it is closed, but also reduce noise, thereby greatly improving the user experience.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Embodiment 1

[0038] See also Figure 2-7 The utility model provides a side-pressure pulley assembly, comprising a sliding seat 1 for installation at the bottom of a door leaf, a pulley frame 7 slidably matched with the sliding seat 1, and a slider 5 slidably arranged on the sliding seat 1 and transmission-matched with the pulley frame 7, the slider 5 being used for transmission connection with a transmission bar; wherein, a guide pulley 10 is provided on the pulley frame 7, and a first slide groove 101 for sliding the slider 5 is provided on the sliding seat 1; therefore, when the transmission bar is driven to slide to drive the slider 5 to slide on the first slide groove 101, the sliding seat 1 and the pulley frame 7 can be further driven to move sideways relative to each other, thereby causing the door leaf to side-press the guide pulley 10.

[0039] Therefore, by arranging the slider 5 between the transmission bar and the pulley frame 7 for transmission cooperation, and the sliding seat 1 is provided with a first slide groove 101 for the slider 5 to slide, since the processing accuracy of the first slide groove 101 can be guaranteed, it can be ensured that the slider 5 does not shake when sliding on the first slide groove 101, thereby avoiding the pulley frame 7 that is transmission-coordinated with it from shaking, and further avoiding the sliding seat 1 and the door leaf from shaking. Therefore, the side pressure pulley assembly of the present application can not only ensure the sealing of the door leaf when it is closed, but also reduce noise, greatly improving the user experience.

[0040] Specifically, the sliding seat 1 is also provided with a cavity which is connected to the first sliding groove 101 and is open at one end, and two second sliding grooves 102 which are connected to the cavity and are located on the left and right sides of the cavity. The pulley frame 7 is arranged on the cavity and the two sides of the pulley frame 7 are provided with convex strips 7011 which are slidably matched with the second sliding grooves 102; preferably, the first sliding groove 101 is extended in the left and right directions, and the second sliding groove 102 is extended in the front and back directions. When the sliding block 5 is driven to slide in the left and right directions on the first sliding groove 101, the sliding seat 1 can be driven to move in the front and back directions relative to the pulley frame 7 (i.e., move laterally) through the transmission cooperation between the first sliding groove 101 and the pulley frame 7.

[0041] See also Figure 4 The side pressure pulley assembly also includes a first slide groove plate 2 arranged on the sliding seat 1 at intervals in front and back and located in the cavity. One side of the first slide groove plate 2 is bent and covers the side wall of the first slide groove 101. The first slide groove plate 2 is made of stainless steel and has a relatively smooth surface, thereby reducing the friction generated when the slider 5 slides on the first slide groove 101, making it slide more smoothly. Similarly, the side pressure pulley assembly also includes a second slide groove plate 3 arranged in the second slide groove 102 at intervals in the left and right and matching its shape. The second slide groove plate 3 is also made of stainless steel and has a relatively smooth surface, thereby reducing the friction generated when the sliding seat 1 and the pulley frame 7 move relative to each other, making the sliding between the two smoother.

[0042] Preferably, the wear-resistant sleeve 8 is sleeved on the convex strip 7011 of the pulley frame 7, and the wear-resistant sleeve 8 is in sliding contact with the second slide slot plate 3. Therefore, by providing the wear-resistant sleeve 8, the pulley frame 7 and the second slide slot plate 3 can be prevented from directly sliding in contact with each other to cause wear, thereby extending the service life thereof, and when the wear-resistant sleeve 8 is worn, it is also convenient to disassemble and replace it, and the operation is simple and convenient.

[0043] Furthermore, the side pressure pulley assembly also includes a driving shaft 4 passed through the slider 5, and the pulley frame 7 is provided with a guide groove for one end of the driving shaft 4 to extend into and engage and slide with each other; therefore, when the slider 5 is driven to slide on the first slide groove 101, the sliding seat 1 and the pulley frame 7 can be relatively shifted laterally through the engagement and sliding cooperation between the driving shaft 4 and the guide groove.

[0044] The drive shaft 4 also includes a sleeve 6 which is sleeved on one end of the drive shaft 4 and is in sliding contact with the guide groove. Thus, by providing the sleeve 6, the drive shaft 4 and the guide groove are prevented from directly sliding in contact and causing wear, and when the sleeve 6 is worn, it is convenient to disassemble and replace it, and the operation is simple and convenient.

[0045] Specifically, the pulley frame 7 includes a pulley frame body 701 and a cover plate 702 covering the pulley frame body 701, a guide hole 7021 is provided on the cover plate 702, a groove 7013 connected to the guide hole 7021 and matching the shape thereof is provided on the pulley frame body 701, and the guide hole 7021 cooperates with the groove 7031 to form the above-mentioned guide groove. Among them, two convex strips 7011 are respectively integrally formed on the left and right sides of the pulley frame body 701; two convex columns 7012 are also spaced apart on the pulley frame body 701 along the left and right directions, and the two guide pulleys 10 are respectively mounted on the two convex columns 7012.

[0046] It should be noted that when the slider 5 slides on the first slide groove 101, the slider 5 simultaneously contacts the cover plate 702; therefore, in order to improve the sliding smoothness of the slider 5, the cover plate 702 is also made of stainless steel, and its surface is relatively smooth, thereby reducing the friction generated between the slider 5 and the cover plate 702 when sliding.

[0047] Among them, the slider 5 includes a slider body 501 and a slider sleeve 502 mounted on the slider body 501. The slider body 501 is slidably mounted on the first slide groove 101 through the slider sleeve 502, thereby avoiding wear caused by direct contact between the slider body 501 and the first slide groove 101, and when the slider sleeve 502 is worn, it is also convenient to disassemble and replace it.

[0048] See also Figure 5 and Figure 7 The pulley frame body 701 is also provided with an avoidance hole 7014 connected to the groove 7013 , and the shaft sleeve 6 can pass through the avoidance hole 7014 and be sleeved on the driving shaft 4 .

[0049] Therefore, when it is necessary to assemble the side pressure pulley assembly of the present application, first install the slider 5 and the pulley frame 7 on the sliding seat 1 in sequence, then pass the drive shaft 4 through the slider 5 from top to bottom and extend it into the guide groove, and then pass the sleeve 6 through the avoidance hole 7014 from bottom to top and sleeve it on the drive shaft 4 to complete the assembly.

[0050] It also includes a blocking cover 9, which is arranged on the avoidance hole 7014 to achieve sealing, thereby making the product appearance more neat and beautiful, and also preventing dust and other impurities from falling into the groove and causing transmission problems.

[0051] Furthermore, the side pressure pulley assembly further includes a positioning member 11 detachably arranged on the pulley frame 7, and the positioning member 11 is in conflict with the pulley frame 7 to achieve the initial positioning of the pulley frame 7. Specifically, the positioning member 11 is an elastically deformable clamping ring, and a positioning clamping groove 103 is provided on the sliding seat 1, and the clamping ring is detachably clamped on the positioning clamping groove 103.

[0052] When assembling for the first time, the pulley frame 7 needs to be initially positioned, so the positioning member 11 needs to be installed on the positioning slot 103; after the assembly is completed, the positioning member 11 can be removed to avoid interference with other parts.

[0053] Embodiment 2

[0054] See also Figure 8 The utility model further provides a push-pull side pressure pulley assembly, comprising the side pressure pulley assembly of the above-mentioned embodiment 1 and a push-pull pulley assembly 12 arranged on the side pressure pulley assembly. Specifically, the push-pull pulley assembly comprises two fixing plates 121 arranged at intervals on the front and rear sides of the side pressure pulley assembly and two pulleys 122 clamped and fixed between the two fixing plates 121 and arranged at intervals on the left and right sides of the side pressure pulley assembly, and the pulleys 122 are slidably arranged on the lower guide rail to realize the push-pull movement of the door leaf.

[0055] To sum up, the utility model provides a side pressure pulley assembly and a push-pull side pressure pulley group having the same, which realizes transmission cooperation by arranging a slider 5 between the transmission bar and the pulley frame 7, and a first slide groove 101 for sliding the slider 5 is provided on the sliding seat 1. Since the processing accuracy of the first slide groove 101 can be guaranteed, it can be ensured that the slider 5 does not shake when sliding on the first slide groove 101, thereby avoiding shaking of the pulley frame 7 that is transmission-coordinated with it, and further avoiding shaking of the sliding seat 1 and the door leaf; therefore, the side pressure pulley assembly of the present application can not only ensure the sealing of the door leaf when it is closed, but also reduce noise, thereby greatly improving the user experience.
