Description

Technical Field

[0001] The utility model relates to the technical field of hanging wheels, in particular to a single-axis hanging wheel structure. Background Art

[0002] A hanging door, also called a sliding hanging door, a sliding door, etc., is a type of sliding door. It adopts a hanging wheel type, and the door leaf is hoisted on the upper guide rail through the hanging wheel, so that there is no need to install a guide rail under the door leaf. When using a hanging wheel to install a hanging door, since the existing profiles and hardware are produced separately and then assembled, errors will inevitably occur during the production of profiles and hardware, and there will be a certain gap during assembly. At the same time, there will also be a certain error between the door body and the installation site, which often causes poor cooperation between the hanging wheel and the door body, resulting in looseness and unsmooth sliding. This requires adjusting the hoisting height of the door body according to the specific installation height at the construction site so that the door body can slide smoothly, and the gaps between the door body and the door frame, and between the door bodies will not be too large;

[0003] Reference Figures 6-7 , the current hanging wheel mainly includes a hanging piece, and the hanging piece is respectively provided with two pairs of corresponding pulleys. A screw rod is threadedly connected to the middle of the hanging piece. The distance between the door body and the hanging wheel group is adjusted through the screw rod of the hanging wheel group. Although this structure can adjust the hoisting height, it is necessary to remove the hanging wheel group from the guide rail and then turn the screw rod for adjustment. Such an adjustment process is cumbersome. Moreover, although the connection with the door frame is increased by multiple pulleys, its connection with the door body mainly relies on the screw rod, and the stress point is small. The screw rod needs to bear the weight of the door body all the time, which causes accelerated damage to the hanging wheel. Content of the Utility Model

[0004] The utility model aims to provide a single-axis hanging wheel structure to achieve the purpose of conveniently adjusting the hoisting height and improving the connection firmness between the hanging wheel and the door body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in the attached drawings, a single-axis hanging wheel structure of the present invention includes a door frame 72 and a door body 71. A guide rail groove is provided in the door frame 72. As Figures 1-4 shown, it includes an adjusting screw 1, a slider 2, a roller 3, and a mounting seat 4 for connecting the door body 71. The roller 3 is preferably provided with 2. Two panels 5 are respectively arranged between the slider 2 and the roller 3, and then passed through in sequence by a wheel pin 6. The two panels 5 are provided with inclined grooves 50. The roller 3 is rotatably connected to the slider 2 through the wheel pin 6. The wheel pin 6 is slidably connected to the inclined groove 50 along the length direction of the inclined groove 50. One end of the adjusting screw 1 is threadedly connected to the end of the slider 2, and the other end is rotatably connected to the panel 5. And a screwing part 11 is provided at the end of the adjusting screw 1 away from the slider 2. The orientation of the screwing part 11 corresponds to the pushing and pulling direction of the hanging door. A U-shaped depression is also provided on the curved surface of the roller 3. A guide rail for the roller 3 to slide is arranged in the door frame 72, and the guide rail is provided with a convex part matching the U-shaped depression. A T-shaped groove 40 is provided at the bottom of the mounting seat 4, and the T-shaped groove 40 is used to connect and install the door body 71.

[0023] For a single-axis hanging wheel structure of the present invention, by arranging the wheel pin 6 on the inclined groove 50 provided on the panel 5, the wheel pin 6 is connected to the slider 2 and the roller 3. By screwing the adjusting screw 1 on the slider 2, the slider 2 is moved along the length direction of the inclined groove 50, so as to drive the roller 3 up and down. At the same time, during the adjustment process, there is no need to remove the guide rail of the door frame 72, achieving the purpose of easy adjustment, making the installation of the hanging door simpler and more convenient. Moreover, the hanging wheel is connected to the door body 71 through the mounting seat 4. The T-shaped groove 40 is provided on the mounting seat 4 to cooperate with the T-shaped hanging rib 7 provided on the top of the door body 71, increasing the force-bearing surface with the door body 71, so that the stability of the door body 71 is better;

[0024] During installation, the hanging wheels are generally installed at both ends of the top of the door body 71. If the door body 71 is heavier and larger in area, more than two hanging wheels can also be installed. The mounting seat 4 is connected to the T-shaped hanging rib 7 of the door body 71 through the T-shaped groove 40, and the hanging wheels are placed in the door frame 72, and the door body 71 and the mounting seat 4 are fixed. After fixing, the adjusting screw 1 is screwed to drive the slider 2 to slide along its length direction. Under the limitation of the inclined groove 50, the wheel pin 6 gradually moves up / down along with the inclined groove 50, so that the roller 3 and the slider 2 move up and down accordingly, achieving the purpose of adjusting the height.

[0025] In this embodiment, the T-slot 40 is used to plug and fix the T-shaped hanging rod 7 fixedly installed on the top of the door body 71. The length of the T-shaped hanging rod 7 corresponds to the width of the door body 71, so that the mounting seat 4 can be installed at any position on the top of the door body 71. Preferably, the mounting seat 4 is arranged at both ends of the top of the door body 71. The T-shaped hanging rod 7 and the T-slot 40 cooperate to prevent the door body 71 from being separated from the mounting seat 4. The mutual plugging of the T-slot 40 and the T-shaped hanging rod 7 allows the hanging wheel and the door body 71 to be hooked with each other, which can effectively prevent them from falling. The mounting seat 4 is fixedly connected to the T-shaped hanging rod 7 by screws, and a recessed portion for the screw to be screwed in is provided between the T-shaped slot 40 and the T-shaped hanging rod 7. A recessed portion for the screw to be screwed in can be provided in the T-shaped slot 40, and the T-shaped hanging rod 7 is also provided with a recessed portion at a corresponding position, which is more conducive to screwing in the screw. The screw is screwed into the T-shaped slot 40 from the end of the mounting seat 4, and is located between the T-shaped slot 40 and the T-shaped hanging rod 7 and kept open, so that the T-shaped hanging rod 7 is tightly against the T-shaped slot 40, thereby ensuring the fixed connection between the door body 71 and the mounting seat 4.

[0026] In this embodiment, the panel 5 is arranged inside the mounting seat 4, and a clip 51 rotatably connected to the adjusting screw 1 is provided at one end of the panel 5, which can provide a plane corresponding to the end of the adjusting screw 1, so that the adjusting screw 1 can be positioned between the panels 5, the clip 51 is U-shaped, and the adjusting screw 1 passes through the middle of the clip 51, the mounting seat 4 is provided with a slot 41 corresponding to the inclined slot 50, the roller 3 is arranged on both sides of the mounting seat 4, and a mounting slot 510 is provided at one end of the panel 5, and the clip 51 is inserted into the mounting slot 510. The clip 51 can be used to connect two panels 5, and the mounting slot 510 of one panel 5 is passed through the clip 51 and the adjusting screw 1 is installed, and then the clip is passed into the mounting slot 510 of the other panel 5.

[0027] It should be noted that in actual applications, since the hanging wheel needs to withstand a large gravity, it needs better firmness and strength. The panel 5 and the mounting seat 4 are an integrated structure, which is more firm and has better strength. When the panel 5 and the mounting seat 4 are integrated, they are directly made of metal with higher hardness, that is, the panel 5 and the two side walls of the mounting seat 4 are integrated, and the inclined groove 50 of the panel 5 extends to the mounting seat 4, so that the two side plates of the mounting seat 4 can be regarded as the panel 5, and the rollers 3 are arranged on both sides of the mounting seat 4 and connected to the slider 2 arranged in the mounting seat 4 through the wheel pin 6;

[0028] The panel 5 and the mounting base 4 are of a split structure. Both of the two panels 5 are fixedly arranged on both sides inside the mounting base 4. The mounting base 4 is provided with a slot 41 corresponding to the inclined slot 50. The panel 5 and the mounting base 4 are produced separately, and then the panel 5 is fixed on both sides inside the mounting base 4. The inclined slot 50 overlaps with the slot 41, and the area of the slot 41 completely covers the inclined slot 50, avoiding the slot 41 from restricting the up-and-down adjustment of the hanging wheel. The slot 41 can also be set to be the same slot as the inclined slot 50. By setting it as a split structure like the mounting base 4 and the panel 5, the mounting base 4 can be formed by profile extrusion. Then, the panel 5 is made of other metals with higher hardness and fixedly connected to the mounting base 4 to provide overall support. In this way, the production cost is lower and the production is more convenient.

[0029] In this embodiment, a buffer abutting portion 201 cooperating with the buffer 721 is arranged at the top of the slider 2. The buffer abutting portion 201 protrudes upward from the panel 5 and the mounting base 4. It should be noted that the buffer 721 is a commonly used existing accessory in the sliding door. It can slow down the speed of the door body 71 when the door body 71 is about to close, so that it closes slowly, preventing pinching hands and damage to the door body 71 caused by collision. Generally, the clamping position of the buffer 721 is in a C shape, and generally, a clamping post adapted to the C-shaped clamping position needs to be installed on the door body 71. The protruding buffer abutting portion 201 arranged at the top of the slider 2 can act as the clamping post and cooperate with the clamping position of the buffer 721.

[0030] The above embodiments are the preferred embodiments of the present invention. All structures similar to the present invention and equivalent changes made shall fall within the protection scope of the present invention.
