Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, specifically relating to a side-pressure door and window sliding device and pulley. Background Technology

[0002] Side-pressure sliding door and window systems require squeezing the sealing strip to achieve water and air tightness when locked. Therefore, the final stage of squeezing the sealing strip is often the stage where the handle requires the most force. In particular, the larger the area of ​​the door or window sash, the longer the circumference of the sealing strip. As a result, the squeezing force of the sealing strip on the window sash is greater when locked, which leads to greater handle operation force, affecting the user's operating feel and making it more strenuous. Utility Model Content

[0006] The first bracket is fixedly connected to the sash frame, and the second bracket is slidably engaged with the fixed frame to enable the door and window sash to be pushed and pulled. The first bracket and the second bracket can be relatively translated along the thickness direction of the sash frame.

[0007] The translation drive assembly includes a swing arm, a drive member, and a driven member. The swing arm is rotatably connected to the first bracket. One side of the swing arm's rotation connection point is provided with a drive groove, and the other side is provided with a sliding groove that connects to the driven member. The first bracket is provided with a first guide groove extending along the thickness direction of the fan frame. The driven member passes through the first guide groove and connects to the second bracket. The drive member moves along the length direction of the fan frame with the transmission bar of the hardware system. The extension direction of the drive groove is inclined relative to the movement direction of the drive member. The extension direction of the sliding groove is horizontal relative to the length direction of the swing arm. When the drive member moves, it cooperates with the drive groove to cause the swing arm to rotate. The direction in which the drive member moves away from the driven member is the locking direction.

[0008] In a preferred embodiment of the present invention, the first bracket is provided with a second guide groove, which extends along the length direction of the fan frame; the driving component is adapted to be embedded in the second guide groove.

[0009] Preferably, there are two second guide grooves, located on both sides of the first guide groove; both ends of the first bracket have openings. In this embodiment, to facilitate the connection between the swing arm and the first bracket, two protruding posts are provided on the first bracket, located on both sides of the first guide groove; the function of the protruding posts is to connect with the swing arm to realize the rotation of the swing arm. The protruding posts and the swing arm can be connected by riveting, direct sleeve, or bearing connection, etc., to realize the rotation of the swing arm.

[0010] In a preferred embodiment of this utility model, the first bracket has two opposing L-shaped grooves on the side facing the second bracket, and the second bracket has L-shaped blocks at both ends; the two L-shaped grooves are fitted into each other in a one-to-one correspondence.

[0011] In a preferred embodiment of this utility model, the first bracket is provided with at least one support assembly on the side facing the second bracket; the support assembly includes a retainer and a plurality of rolling elements, the retainer is provided with a plurality of limiting cavities, and the plurality of rolling elements are located in the plurality of limiting cavities one by one and can roll along the thickness direction of the fan frame; the first bracket and the support assembly are provided with receiving cavities at corresponding positions, and the retainer or a part thereof is located in the receiving cavity; the rolling elements are in contact with the first bracket and the second bracket.

[0012] Preferably, a first wear-resistant pad is provided in the receiving cavity, and a second wear-resistant pad is provided at the contact point between the second bracket and the rolling element.

[0013] In a preferred embodiment of the present invention, the first bracket has a cavity on the side away from the second bracket, the first guide groove is disposed in the cavity, and a third wear-resistant pad is disposed in the cavity.

[0014] In a preferred embodiment of the present invention, the first bracket has a mounting cavity on the side away from the second bracket, and the translation drive assembly is disposed in the mounting cavity; the first bracket has a protective plate on the side away from the second bracket, and the protective plate covers the mounting cavity.

[0015] In a preferred embodiment of this utility model, the translation drive assembly further includes a drive bar, which is connected to the drive component. The drive bar and the drive component move with the transmission bar of the hardware system. One or both ends of the drive bar extend out of the first bracket, and one or both ends of the drive bar are provided with mounting holes and locking holes.

[0016] A pulley system includes a pulley assembly and the side-pressure door / window sliding device; the pulley assembly includes two sets of pulleys, which are respectively connected to both sides of the second bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This utility model's side-pressure door and window sliding device utilizes a swing arm to connect the driving component and the driven component, so that the driving force arm on the driven component gradually increases when locking the door or window sash, thereby achieving the purpose of saving effort and improving the user's feel. At the same time, during the locking or opening process, the first guide groove on the first bracket guides and restricts the driven component, which helps to improve the reliability of the relative translation of the driven component and the second bracket.

[0019] Specifically, when the door or window sash needs to be locked, the transmission bar of the hardware system moves, causing the driving component to move away from the driven component. Simultaneously, the driving component slides in the driving groove, causing the swing arm to rotate. This allows the driven component, guided by the first guide groove, to move the second bracket relative to the first bracket. During the movement of the driving component, the lever arm length at the rotational connection point between the driving component, the swing arm, and the first bracket continuously increases, reaching its longest point when the door or window sash is pressed against the rubber strip (i.e., when the handle's operating force is at its maximum), resulting in a significant effort-saving effect.

[0048] To better understand the above-mentioned objectives, features, and advantages of this utility model, it will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0050] See Figures 1-13 This embodiment discloses a pulley system, including a pulley block 3 and a side-pressure window / door sliding device. The side-pressure window / door sliding device includes a first bracket 1, a second bracket 2, and a sliding drive assembly 6. The first bracket 1 is fixedly connected to the sash frame 11, and the second bracket 2 is slidably engaged with a fixed frame 12 to allow the window / door sash to be pushed and pulled. The first bracket 1 and the second bracket 2 can slide along the thickness direction of the sash frame 11 (i.e.,...). Figures 9-12 The left and right directions (which can also be understood as the inward and outward directions of the door and window sashes) are relatively translated.

[0051] The translation drive assembly 6 includes a swing arm 601, a drive member 603, and a follower 604. The swing arm 601 is rotatably connected to the first bracket 1. One side of the rotation connection point of the swing arm 601 is provided with a drive groove 6011, and the other side is rotatably connected to the follower 604. The first bracket 1 is provided with a first guide groove 101 extending along the thickness direction of the fan frame 11. The follower 604 passes through the first guide groove 101 and is connected to the second bracket 2. The drive member 603 follows the transmission bar of the hardware system along the length direction of the fan frame 11. The extension direction of the drive groove 6011 is inclined relative to the movement direction of the drive member 603; the extension direction of the sliding groove 6012 is horizontal relative to the length direction of the swing arm 601, or it can be understood as parallel to the length direction of the swing arm 601, so that the driven member 604 has a certain sliding space in the sliding groove 6012; when the drive member 603 moves, it cooperates with the drive groove 6011 to cause the swing arm 601 to rotate, and the direction in which the drive member 603 moves away from the driven member 604 is the locking direction.

[0052] Furthermore, the first bracket 1 is provided with a second guide groove 102, which extends along the length of the sash frame 11; the driving member 603 is adapted to be embedded in the second guide groove 102. Driven by the transmission bar of the door and window hardware system, the transmission bar generally moves in a straight line. Therefore, by the driving member 603 moving linearly with the transmission bar and simultaneously engaging with the driving groove 6011, the swing arm 601 can be driven to rotate relative to the first bracket 1. This causes the driven member 604, guided by the first guide groove 101, to drive the second bracket 2 to move along the thickness direction of the sash frame 11, thus achieving relative translation between the second bracket 2 and the first bracket 1. In this embodiment, the addition of the second guide groove 102 to the first bracket 1 further guides the movement direction of the driving member 603 and limits its movement distance, making the movement of the driving member 603 more reliable and stable. This improves the stability and reliability of the interconnected components such as the swing arm 601, the driven member 604, the second bracket 2, and the transmission bar.

[0053] See Figure 3 and 5 In this embodiment, two second guide grooves 102 are provided, located on both sides of the first guide groove 101 respectively; both ends of the first bracket 1 are provided with openings 104. In this embodiment, to facilitate the connection between the swing arm 601 and the first bracket 1, two protrusions 103 are provided on the first bracket 1, located on both sides of the first guide groove 101 respectively; the function of the protrusions 103 is to connect with the swing arm 601 to realize the rotation of the swing arm 601. The protrusions 103 and the swing arm 601 can be connected by riveting, direct sleeve, or bearing connection, etc., to realize the rotation of the swing arm 601. In this embodiment, two second guide grooves 102, openings 104, and protrusions 103 are provided and located on both sides of the first guide groove 101 respectively, so that the swing arm 601 can be set on one side of the first guide groove 101 according to selection, improving the adaptability and flexibility of the device and having a bidirectional connection function.

[0054] Furthermore, the first bracket 1 has two opposing L-shaped grooves 106 on the side facing the second bracket 2, and the second bracket 2 has L-shaped blocks 201 at both ends; the two L-shaped grooves 106 are fitted into each other in a one-to-one correspondence. Through the cooperation between the L-shaped grooves 106 and the L-shaped blocks 201, on the one hand, the length direction of the two can be restricted, improving the assembly reliability of the two; on the other hand, this cooperation does not affect the relative translation of the two, the structure is simple and the assembly is convenient.

[0055] Furthermore, the side of the first bracket 1 facing the second bracket 2 is provided with at least one support assembly 5. The support assembly 5 includes a retainer 501 and a plurality of rolling elements 502. The retainer 501 is provided with a plurality of limiting cavities 5011, and the plurality of rolling elements 502 are located one-to-one in the plurality of limiting cavities 5011 and can roll along the thickness direction of the fan frame 11. The first bracket 1 and the support assembly 5 are provided with receiving cavities 107, and the retainer 501 or a part thereof is located in the receiving cavity 107. The rolling elements 502 are in contact with the first bracket 1 and the second bracket 2. In this embodiment, one, two or other numbers of support assemblies 5 can be provided, which can be flexibly adjusted according to the actual situation. For example, in this embodiment, there are two support assemblies 5 between the first bracket 1 and the second bracket 2, which are located on both sides of the first guide groove 101, respectively. In this embodiment, the rolling element 502 can adopt a structure such as a needle roller or a ball roller. The first bracket 1 and the second bracket 2 support each other on the rolling element 502, so that when the first bracket 1 and the second bracket 2 move relative to each other, the friction between them can be reduced and the smoothness of the movement can be improved. At the same time, it can also reduce the force required by the user to lock the door and window sash, and the feel is better.

[0056] A first wear-resistant gasket 7 is provided in the receiving cavity 107, and a second wear-resistant gasket 8 is provided at the contact point between the second bracket 2 and the rolling element 502. The use of the first wear-resistant gasket 7 and the second wear-resistant gasket 8 minimizes wear caused by translation of the first bracket 1 and the second bracket 2, thus extending their service life. Of course, the first bracket 1 and the second bracket 2 can also be made of wear-resistant material.

[0057] See Figure 3 and 5 In this embodiment, the first bracket 1 has a recess 108 on the side away from the second bracket 2, and a first guide groove 101 is disposed in the recess 108. A third wear-resistant pad 9 is disposed in the recess 108. To facilitate the connection between the driven member 604 and the second bracket 2, a clearance hole 901 for the driven member 604 can be provided on the third wear-resistant pad 9. In this embodiment, the driven member 604 can adopt a pin structure to facilitate a slidable connection with the swing arm 601, such as a hinge. In addition, the driven member 604 in this embodiment has a support portion, which is enlarged and supported on the third wear-resistant pad 9. The second bracket 2 in this embodiment has an assembly hole. When the driven member 604 is inserted into the assembly hole, the driven member 604 can drive the second bracket 2 to translate relative to the first bracket 1.

[0058] Furthermore, the side of the first bracket 1 away from the second bracket 2 is provided with a mounting cavity 105, and the translation drive assembly 6 is disposed in the mounting cavity 105; the side of the first bracket 1 away from the second bracket 2 is provided with a protective plate 10, which covers the mounting cavity 105. This arrangement helps to protect the translation drive assembly 6, especially by blocking dust, metal shavings, etc., ensuring the smooth operation of all components within the device. During the installation of hardware systems on construction sites, situations often arise where there is a lot of dust, sand, gravel, and mortar easily falling into the transmission mechanism, or aluminum shavings from profiles may fall into the transmission mechanism during the screwing and installation of hardware, thus affecting the smooth operation of the transmission mechanism. Therefore, the protective plate 10 effectively solves this technical problem, with a simple structure and good effect.

[0059] The translation drive assembly 6 in this embodiment also includes a drive bar 602, which is connected to a drive member 603. The drive bar 602 and the drive member 603 move with the transmission bar of the hardware system. Both ends of the drive bar 602 extend out of the first bracket 1, and each end of the drive bar 602 is provided with a mounting hole 6021 and a locking hole 6022. Further, in this embodiment, the mounting hole 6021 at one end of the drive bar 602 can be used to connect with the connector 1301 of the corner bracket 13 of the sliding door and window. The connector 1301 is provided with a protrusion 13011. During connection and assembly, the protrusion 13011 is embedded in the mounting hole 6021, and then a screw is used to lock it to the connector 1301 through the locking hole 6022, thus completing the connection between the drive bar 602 and the corner bracket 13. The operation is convenient and there is no need to install an intermediate transmission structure. The other end of the drive bar 602 in this embodiment can be connected to the connecting part, and the connection method can be similar to that of the corner bracket 13.

[0060] In another embodiment, the drive bar 602 of this embodiment can also be regarded as the transmission bar of the door and window hardware system, that is, the drive bar 602 of this embodiment is associated with the handle and transmission device of the hardware system.

[0061] The pulley block 3 in this embodiment includes two sets of pulleys 301, which are respectively connected to both sides of the second bracket 2. See also Figure 1 , Figure 2 and Figure 8 In this embodiment, the pulley system can be a lower pulley system applied to side-pressing sliding doors and windows. The pulley assembly 3 also includes two guide wheels 4 disposed at the bottom of the second bracket 2. The guide wheels 4 are perpendicular to the rotation direction of the pulley 301. The bottom of the second bracket 2 is provided with two connecting rods 202, and the guide wheels 4 are disposed on the connecting rods 202. The pulley assembly 3 is supported on the lower guide rail of the door and window frame. Other specific embodiments of the pulley system can be found in the prior art. In addition, the pulley system in this embodiment can also be an upper pulley system, that is, an upper pulley system applied to side-pressing sliding doors and windows.

[0062] In addition, the side-pressure door and window sliding device of this embodiment can also be applied to the hook-locking point of side-pressure sliding doors and windows.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
