Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a sliding anti-jump mechanism for doors and windows. Background Technology

[0002] Existing sliding door and window structures typically include a door / window body, left and right extending guide rails, and a pulley assembly mounted at the bottom of the door / window body. The pulley assembly is rotatably mounted at the bottom of the door / window body via a pivot, and its rims slide against the guide rails to achieve horizontal movement of the door / window. Specifically, when an external force is applied to move the door / window body, the pulleys rotate around their pivots and achieve guiding and limiting through frictional contact between their rims and the guide rails. At this time, rolling friction is generated between the pulleys and the guide rails, allowing the door / window body to translate along the extension direction of the guide rails.

[0003] However, when a user closes a door or window, due to inertia, a rigid collision occurs between the door / window body and the frame. This reaction force is transmitted to the door / window body via a pivot, causing it to shift in the opposite direction and vibrate and bounce vertically. This unexpected rebound motion can easily cause mechanical damage to the door / window body; more seriously, it may cause the bounced door / window body to detach from the guide rail and impact the user, posing a certain safety hazard to the sliding of doors and windows. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sliding anti-jump mechanism for doors and windows, which can reduce the impact of jumping door and window bodies falling off the guide rail on users and reduce installation hazards when doors and windows are moved horizontally.

[0005] To solve the above-mentioned technical problems, the present invention provides a sliding anti-jump mechanism for doors and windows, including a guide rail extending to the left and right, an anti-jump seat installed on the door or window, and a roller rotatably connected to the anti-jump seat. The roller is used to abut against the guide rail so that the anti-jump seat can move left and right relative to the guide rail. The guide rail is provided with an anti-jump groove with an opening facing backward, and the anti-jump seat is provided with an anti-jump protrusion extending into the anti-jump groove.

[0006] As an improvement to the above solution, the anti-jumping bump is located below the roller.

[0007] As an improvement to the above solution, the roller is provided with a connecting groove for the upper part of the guide rail to extend into, and the upper side of the guide rail is used to abut against the bottom of the connecting groove.

[0008] As an improvement to the above solution, the lower end of the roller is higher than the upper end of the guide rail opening.

[0009] As an improvement to the above solution, the distance between the upper side of the anti-jumping protrusion and the upper end of the guide rail opening is less than the depth of the connecting groove.

[0010] As an improvement to the above solution, the sliding anti-jump mechanism for doors and windows of this utility model also includes mounting bolts and an inner cover. The front side of the anti-jump seat is provided with a connecting boss, and the rear side of the roller is provided with a connecting cavity that is rotatably connected to the connecting boss. The front side of the roller is provided with a first mounting through hole that penetrates the connecting cavity, and the connecting boss is provided with a second mounting through hole that penetrates the rear side of the anti-jump seat. The mounting bolt is used to pass through the first mounting through hole and the second mounting through hole and be threadedly connected to the inner cover.

[0011] As an improvement to the above solution, the front side of the inner cover is provided with a connecting cylinder for connecting doors and windows, and the front side of the connecting cylinder is provided with a threaded hole for threaded connection with the mounting bolt.

[0012] As an improvement to the above solution, a connecting plate for connecting doors and windows is provided on the rear side of the anti-jump seat below the connecting boss.

[0013] As an improvement to the above solution, the sliding anti-jump mechanism for doors and windows of this utility model also includes an outer cover that engages with the front side of the roller and is used to cover the mounting bolts.

[0014] As an improvement to the above solution, the front side of the roller is provided with a locking ring groove, and the rear circumference of the outer cover is provided with a plurality of arc-shaped locking strips for engaging and connecting with the locking ring groove.

[0015] The present invention has the following beneficial effects:

[0016] This utility model discloses a sliding anti-jump mechanism for doors and windows. Through the cooperation of guide rails, anti-jump seats, rollers, anti-jump grooves, and anti-jump protrusions, when a door or window experiences a rigid collision causing it to bounce, the anti-jump grooves and protrusions limit the amplitude of the bounce, reducing the risk of the door or window body detaching from the guide rail and impacting the user, and lowering installation hazards during door and window sliding.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0029] like Figures 1 to 4 As shown in the figure, a sliding anti-jump mechanism for doors and windows in this embodiment of the present invention includes a guide rail 100 extending left and right, an anti-jump seat 200 mounted on the door or window, and rollers 300 rotatably connected to the anti-jump seat 200. The rollers 300 are used to abut against the guide rail 100 so that the anti-jump seat 200 can move left and right relative to the guide rail 100. In fact, at least two sets of anti-jump seats 200 and rollers 300 are installed on the door or window with left and right intervals, and the two sets of anti-jump seats 200 and rollers 300 simultaneously drive the door or window to move left and right relative to the guide rail 100, preventing the door or window from swaying during the left and right movement relative to the guide rail 100. The rollers 300 contact the guide rail 100 and work together with the anti-jump seat 200 and the door or window on the guide rail 100. When an external force is applied to the door or window, causing the door or window to move horizontally, the combined action of the rollers and the guide rail 100 restricts the direction of movement of the door or window, allowing the door or window to move left and right relative to the guide rail 100.

[0030] The guide rail 100 is provided with an anti-jump groove 110 with the opening facing backward, and the anti-jump seat 200 is provided with an anti-jump protrusion 210 extending into the anti-jump groove 110. In fact, the anti-jump seat 200 is installed on the door and window and moves synchronously with the door and window. When the door and window bounce due to a rigid collision, the anti-jump groove 110 and the anti-jump protrusion 210 limit the jumping range of the door and window (if the guide rail 100 is set below the roller 300, when the door and window jump upward, the anti-jump protrusion 210 of the anti-jump seat 200 abuts against the inner upper side wall of the anti-jump groove 110 or the upper end of the opening of the anti-jump groove 110, which can prevent the door and window from jumping upward; if the guide rail 100 is set above the roller 300, when the door and window jump downward, the anti-jump protrusion 210 of the anti-jump seat 200 abuts against the inner lower side wall of the anti-jump groove 110 or the lower end of the opening of the anti-jump groove 110, which can prevent the door and window from jumping upward). Within a certain range, it can prevent the jumping range of the door and window, reduce the impact of the jumping door and window body falling off the guide rail 100 on the user, and reduce the installation hazards when the door and window are moved horizontally.

[0031] The sliding anti-jump mechanism for doors and windows in this utility model uses a guide rail 100, an anti-jump seat 200, a roller 300, an anti-jump groove 110, and an anti-jump protrusion 210 to cooperate with each other. When the door or window bounces due to a rigid collision, the anti-jump groove 110 and the anti-jump protrusion 210 limit the jumping amplitude of the door or window, reduce the impact of the jumping door or window body falling off the guide rail 100 on the user, and reduce the installation hazards when the door or window is moved horizontally.

[0032] Specifically, the anti-jumping protrusion 210 is preferably located below the roller 300. That is, when the guide rail 100 is located below the roller 300, the roller 300 can transfer the weight of the door, window and anti-jumping seat 200 to the upper side of the guide rail 100, making the contact between the roller 300 and the guide rail 100 tighter, and making it more difficult for the door and window to jump relative to the guide rail 100.

[0033] More specifically, such as Figure 3 As shown, the roller 300 preferably has a connecting groove 310 for the upper part of the guide rail 100 to extend into, and the upper side of the guide rail 100 abuts against the bottom of the connecting groove 310. In practice, after all accessories are installed, the upper part of the guide rail 100 extends into the connecting groove 310. If an external force is applied to the door or window, causing it to move back and forth, the connecting groove 310 restricts the range of movement of the door or window. The front and rear sides of the connecting groove 310 and the front and rear sides of the upper part of the guide rail 100 also limit the range of movement and ensure that the upper side of the guide rail 100 contacts the bottom of the connecting groove 310, preventing the roller 300 from disengaging from the guide rail 100 and reducing the safety hazards of the door or window.

[0034] Furthermore, the lower end of the roller 300 is preferably higher than the upper end of the opening of the guide rail 100 to ensure the exposure of the opening of the guide rail 100, leaving more operating space for the installation of the anti-jumping protrusion 210.

[0035] Furthermore, the distance between the upper side of the anti-jumping protrusion 210 and the upper end of the opening of the guide rail 100 is preferably less than the depth of the connecting groove 310. When the door or window jumps upward, it causes the anti-jumping protrusion 210 on the anti-jumping seat 200 to contact the upper end of the opening of the guide rail 100, restricting the door or window from continuing to jump upward. The upper part of the guide rail 100 is still in the connecting groove 310, and the range of forward and backward movement of the door or window is limited, preventing the roller 300 from derailing due to the jumping of the door or window, and ensuring that the upper part of the guide rail 100 can be inserted into the connecting groove 310 again after the door or window falls.

[0036] It should be noted that the sliding anti-jump mechanism for doors and windows of this utility model preferably includes a mounting bolt 400 and an inner cover 500. The anti-jump seat 200 has a connecting boss 220 on its front side, and the roller 300 has a connecting cavity 320 on its rear side that rotatably connects with the connecting boss 220. The roller 300 has a first mounting through hole 330 penetrating the connecting cavity 320 on its front side, and the connecting boss 220 has a second mounting through hole 230 penetrating the rear side of the anti-jump seat 200. The mounting bolt 400 passes through the first mounting through hole 330 and the second mounting through hole 230 and is threadedly connected to the inner cover 500. In practice, the connecting boss 220 can be a frustum or a combination of multiple coaxially arranged frustums with decreasing outer diameters from rear to front. The inner contour of the connecting cavity 320 matches the outer contour of the connecting boss 220, so that when the connecting boss 220 extends into the connecting cavity 320, the roller 300 can rotate relative to the anti-jump seat 200. When the connecting boss 220 extends into the connecting cavity 320, the stud of the mounting bolt 400 passes through the first mounting through hole 330 and the second mounting through hole 230 in sequence and is threadedly connected to the inner cover 500, so that the head of the mounting bolt 400 abuts against the front side of the roller 300, preventing the roller 300 from moving back and forth away from the connecting boss 220.

[0037] Specifically, the inner cover 500 preferably has a connecting cylinder 510 for connecting to the door and window on its front side, and the connecting cylinder 510 has a threaded hole 520 for threaded connection with the mounting bolt 400 on its front side. In practice, the panel of the door and window can have a round hole for the connecting cylinder 510 to pass through. Before installation, the connecting cylinder 510 first passes through the round hole on the panel of the door and window, and then the mounting nut is tightened to connect with the threaded hole 520, so that the anti-jump seat 200 and the inner cover 500 generate a clamping force on the panel of the door and window, thus realizing the installation of the anti-jump seat 200 on the door and window.

[0038] More specifically, the anti-jump seat 200 preferably has a connecting plate 240 for connecting to doors and windows on its rear side below the connecting boss 220. The connecting plate 240 can be fixed to the door or window by means of through-hole bonding, snap-fit, threaded connection, etc., so that the connecting plate 240 is fixed to the door or window and prevents the anti-jump seat 200 from rotating relative to the door or window.

[0039] It is worth mentioning that the sliding anti-jump mechanism for doors and windows of this utility model preferably includes an outer cover 600 that engages with the front side of the roller 300 and is used to cover the mounting bolt 400. After the mounting bolt 400 is installed, the outer cover 600 engages with the outside of the roller 300 to prevent the mounting bolt 400 from being exposed. In bathroom applications, this provides a certain degree of waterproofing for the mounting bolt 400.

[0040] Specifically, the front side of the roller 300 preferably has a locking ring groove 340, and the rear circumference of the outer cover 600 is evenly distributed with multiple arc-shaped retaining strips 610 for engaging with the locking ring groove 340. Through the cooperation of the multiple arc-shaped retaining strips 610 with the locking ring groove 340, during installation, the multiple arc-shaped retaining strips 610 are aligned with the locking ring groove 340, and the rear side of the outer cover 600 is pushed to engage the multiple arc-shaped retaining strips 610 into the locking ring groove 340, thus achieving the engaging connection between the outer cover 600 and the front side of the roller 300.

[0041] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
