Abstract
Description
Technical Field
[0001] This application relates to the field of linkage doors, and in particular to an anti-jump upper wheel and linkage sliding door. Background Technology
[0002] Linked sliding doors use a drive belt and drive wheels to move multiple door panels in tandem. The anti-jump upper wheel is a device on the linked door connected to the drive wheel seat via a belt clip. Currently, anti-jump upper wheels are generally installed using a sliding rail, requiring a certain number of slots to be cut into the door frame's mounting profile to accommodate the rotating pulley and other linkage devices.

Regarding directional descriptions, such as "up," "down," "front," "back," "left," and "right," the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, not indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise expressly defined, terms such as "set," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0026] The following is combined Figures 1 to 6 The embodiments of this application are described below.
[0027] Based on the above, this application provides an anti-jump upper wheel, which includes an anti-jump upper wheel provided by the first aspect of this application, which includes a wheel body 100 and an anti-sway component 200, an anti-jump component 300, a first fastener 400 and a second fastener 500 disposed on the wheel body 100. The wheel body 100 has a first connecting hole 101 and a second connecting hole 102 at both ends.
[0028] The anti-sway component 200 includes a movable plate 210, a guide wheel assembly 220, and a hollow cylinder 230. The movable plate 210 is disposed on the wheel body 100, and the guide wheel assembly 220 is disposed on the movable plate 210 so that when the movable plate 210 is moved, the guide wheel assembly 220 is driven to rotate left and right. The hollow cylinder 230 passes through the guide wheel assembly 220 and the movable plate 210 in sequence and is connected to the first connecting hole 101.
[0029] The anti-jump component 300 includes an anti-jump wheel 330 for preventing the wheel body 100 from jumping upward. The anti-jump wheel 330 is located on one side of the anti-sway component 200, and the second connecting hole 102 is located below the anti-jump wheel 330. The first fastener 400 is threadedly connected to the hollow cylinder 230, and the second fastener 500 is threadedly connected to the second connecting hole 102. The tail ends of the first fastener 400 and the second fastener 500 are provided with protrusions.
[0030] Therefore, by providing the anti-sway component 200, the anti-jump upper wheel is prevented from swaying left and right within the slide rail. By providing the anti-jump component 300, one end of the entire anti-jump upper wheel is prevented from tilting up when the door is pushed and pulled. By providing the protruding part, the first fastener 400 and the second fastener 500 are screwed down to make the protruding part contact the slide rail, so that deformation occurs on the contact surface to further fix the entire anti-jump upper wheel.
[0031] Specifically, the guide wheel assembly 220 includes a movable plate 221 and two guide wheels 240. The two guide wheels 240 are located at both ends of the movable plate 221. A first guide post 222 is provided at the bottom of the movable plate 221, and a first guide groove 211 is provided on the movable plate 210. The first guide post 222 is connected to the first guide groove 211. By increasing the movable plate 221 and the cooperation between the first guide post 222 and the guide groove, the position of the guide wheel assembly 220 can be better controlled.
[0032] The first guide groove 211 includes a strip groove and an arc groove, and there are two corresponding first guide posts 222, each of which is connected to the strip groove and the arc groove respectively. When the wheel body 100 is subjected to an upward force, the guide posts of the anti-jump plate 320 slide within the horizontal groove and the arc groove. The horizontal groove limits the lateral movement range of the anti-jump plate 320, while the arc groove allows the anti-jump plate 320 to be adjusted within a certain angle, thereby better adapting to the movement of the wheel body 100, ensuring that the anti-jump wheel 330 always maintains good contact with the slide rail, preventing the entire anti-jump upper wheel from jumping, and thus enhancing the anti-jump effect of the anti-jump assembly 300.
[0033] In some embodiments, the wheel body 100 is further provided with a first adjusting bolt 600, and one end of the movable plate 210 is threadedly connected to the first adjusting bolt 600. When it is necessary to adjust the anti-jumping effect of the anti-jumping upper wheel, the second adjusting bolt 700 is rotated. Since the movable plate 310 is threadedly connected to the second adjusting bolt 700, the rotational motion is converted into linear motion. That is to say, the movable plate 310 will move axially as the bolt rotates, thereby driving the anti-jumping wheel 330 to move to the appropriate position.
[0034] In some embodiments, the anti-jump assembly 300 further includes a movable plate 310 and an anti-jump plate 320. The movable plate 310 is rotatably connected to the anti-jump plate 320. An anti-jump wheel 330 is disposed on the anti-jump plate 320. A second guide post 322 is provided on one side of the anti-jump plate 320, and a corresponding second guide groove 311 is provided on the movable plate 310. The second guide post 322 is inserted into the second guide groove 311. When the sliding door moves, the wheel 100 may be subjected to an upward force and tend to jump. At this time, the anti-jump wheel 330 contacts the slide rail, and the anti-jump plate 320 slides in the second guide groove 311 through the second guide post 322. The position of the anti-jump wheel 330 is adjusted according to the movement of the wheel 100 to counteract the upward force, thereby effectively preventing the wheel 100 from jumping upward and improving the stability of the anti-jump upper wheel during the movement of the sliding door.
[0035] Reference Figure 3 as well as Figure 4 Specifically, the wheel body 100 is provided with a third guide groove 104, and the movable plate 310 is provided with a protrusion 312 corresponding to the third guide groove 104. The protrusion 312 is inserted into the third guide groove 104 and is movably connected to the guide groove, that is, the protrusion 312 can slide in the guide groove. The guide groove is set laterally, which can limit the lateral movement distance of the anti-jump plate 320, so as to better adjust the position of the wheel body 100, ensure that the anti-jump wheel 330 always maintains good contact with the slide rail, and further prevent the wheel body 100 from jumping.
[0036] In some embodiments, a second adjusting bolt 700 is also provided inside the wheel body 100, and one end of the movable plate 310 is threadedly connected to the second adjusting bolt 700. When it is necessary to adjust the position of the movable plate 310, the second adjusting bolt 700 is rotated. Since the movable plate 310 is threadedly connected to the second adjusting bolt 700, the movable plate 310 will move axially along the wheel body 100 as the bolt rotates, thereby driving the anti-jump wheel 330 to move to the appropriate position.
[0037] In some embodiments, the length of the second adjusting bolt 700 is less than the length of the first adjusting bolt 600, so that the tail of the second adjusting bolt 700 has a clearance opening 103, and the second fastener 500 extends toward the clearance opening 103. When the second fastener 500 is tightened, because the tail of the second adjusting bolt 700 has a clearance opening 103, the second fastener 500 can smoothly extend toward the clearance opening 103 without colliding or interfering with the second adjusting bolt 700. Therefore, by changing the length of the second adjusting bolt 700 to form the clearance opening 103, interference between the second adjusting bolt 700 and the second fastener 500 is avoided, ensuring that the first fastener 400 and the second fastener 500 can be smoothly tightened and play a fixing role, while not affecting the adjustment function of the second adjusting bolt 700 on the movable plate 310.
[0038] In some embodiments, one end of the wheel body 100 is provided with a folded edge 110, and the folded edge 110 is provided with a third connecting hole 111 for connecting with other connecting parts. In this way, when installing the linkage sliding door, the anti-jump upper wheel can be connected with other connecting parts through the third connecting hole 111. Bolts or other connecting parts are passed through the third connecting hole 111 to fix the anti-jump upper wheel in a suitable position, making the installation of the anti-jump upper wheel with other components more convenient.
[0039] See next Figure 6 The second aspect of this application also provides a linked sliding door, including a mounting rail and an anti-jump upper wheel as described in any of the above technical solutions, wherein the anti-jump upper wheel is disposed on the mounting rail. The linked sliding door disclosed in the embodiments of this application, having the aforementioned anti-jump upper wheel, thus possesses all the technical effects of the aforementioned anti-jump upper wheel, which will not be elaborated upon here.
