Description

Technical Field

[0001] The present application relates to the field of sealing window accessories, and in particular to a sealing window lower wheel assembly capable of swinging and translating. Background Art

[0002] Generally, sliding doors and windows are opened and closed by pushing and pulling two or more window sashes or door sashes against each other. Grooves and protrusions that can be engaged with each other are respectively provided at the edges of the two closed doors and windows, and the lower wheel assembly is installed at the bottom of the bottom frame of the door and window, and is used to slide in cooperation with the outer frame slide groove of the door frame or window frame.

[0003] Normally, in order to save effort when pushing and pulling doors and windows open, and to enable two relatively closed doors and windows to quickly close each other, a larger gap will be reserved between the grooves and protrusions at the mutually engaged ends, so that it is convenient to push open the doors and windows and to close them together. However, the disadvantage of such a design is that the gap between the engaged ends of the two mutually closed doors and windows is larger, and it is easy for wind or water to enter a certain gap even in the closed state, resulting in the doors and windows not being closed tightly, and the gap is easily further enlarged by wind and rain. At the same time, even if the doors and windows are closed to each other, if the doors and windows are forgotten to be locked and there is wind, the continuous impact of the wind can easily cause the two closed doors and windows to shake or even move away from each other.

[0004] Therefore, the inventors believe that there is still room for improvement in the sealing effect after the doors and windows are closed to each other, as well as the self-locking ability of the doors and windows when the doors and windows are forgotten to be locked and there is wind.

[0023] The following is combined with Figures 1 to 5 This application is described in further detail.

[0024] The present application embodiment discloses a sealing window lower wheel assembly that can swing and translate, referring to Figure 1 , 2 , including a fixing seat 1, an installation shell 2, and an installation inner shell 3. The installation inner shell 3 is installed in the installation shell 2, the installation shell 2 is installed in the fixing seat 1, and a roller 4 is installed in the installation inner shell 3. Under normal circumstances, the installation inner shell 3 and the installation shell 2 can be relatively displaced, and the relative position between the two can be adjusted. The main purpose of the adjustment is to adapt to door and window installation structures of different heights, that is, a height adjustment component is arranged between the installation shell 2 and the installation inner shell 3, and the height adjustment component includes adjustment pins 5 symmetrically arranged on the outer end surfaces of the two side walls in the length direction of the installation inner shell 3, and the two side walls in the length direction of the installation shell 2 are symmetrically and obliquely arranged with strip adjustment holes 6 for the corresponding side adjustment pins 5 to slide. The adjustment is achieved by an adjustment screw 7 arranged between the installation shell 2 and the installation inner shell 3.

[0025] In order to adjust the installation of the screw 7, a fixed base plate 8 is provided at one end of the mounting inner shell 3 in the length direction, and an adjusting base plate 9 is provided at one end of the mounting outer shell 2 in the length direction. The adjusting base plate 9 is provided with a rotating shaft hole 10, and the fixed base plate 8 is provided with a strip vertical hole 11. An adjusting screw 7 is rotatably arranged between the rotating shaft hole 10 and the strip vertical hole 11. The relative displacement of the mounting outer shell 2 and the mounting inner shell 3 in the length direction is achieved by the rotation of the adjusting screw 7. In this embodiment, limit rings 12 are respectively provided on the opposite sides of the adjusting screw 7 and the strip vertical hole 11. Such a design can make the adjusting screw 7 and the fixed base plate 8 only rotate radially without axial displacement, and the adjusting screw 7 and the rotating shaft hole 10 of the adjusting base plate 9 are threadedly matched.

[0026] When adjustment is needed, the adjusting screw 7 is rotated. Under the action of the adjusting screw 7, the inner shell 3 is displaced in the length direction relative to the outer shell 2. During the displacement, the adjusting pin 5 and the corresponding strip-shaped adjusting hole 6 slide relative to each other, so that the inner shell 3 can be relatively lifted and lowered relative to the outer shell 2. During the lifting and lowering process, the adjusting screw 7 can slide along the strip-shaped vertical hole 11, so that the lifting and lowering function of the inner shell 3 will not be affected. At the same time, it can also provide the function of adjusting power.

[0027] Reference Figure 3 A power drive assembly is arranged in the middle of the top surface of the fixed seat 1, and driving swing arms 13 cooperating with the power drive assembly are respectively arranged on the top surfaces of the fixed seat 1 on opposite sides of the power drive assembly. The driving swing arms 13 are rotatably installed on the top surface of the fixed seat 1, and a driving hole 14 is obliquely arranged on one side of the driving swing arm 13 away from the power drive assembly.

[0028] Among them, the power drive component includes a main driving gear 15 and a transfer gear 16 rotatably installed on the top surface of the fixed seat 1, and the transfer gear 16 and the main driving gear 15 are meshed and transmitted. One driving swing arm 13 is rotatably set on the top surface of the fixed seat 1 and is located on the side of the main driving gear 15 away from the transfer gear 16, and the other driving swing arm 13 is rotatably set on the top surface of the fixed seat 1 and is located on the side of the transfer gear 16 away from the main driving gear 15.

[0029] In this embodiment, the end of the driving swing arm 13 close to the corresponding side main driving gear 15 and the transfer gear 16 is provided with a fan-shaped driving substrate 17, and the fan-shaped driving substrate 17 is respectively provided with fan-shaped teeth 18 meshing with the corresponding side main driving gear 15 and the transfer gear 16. The main driving gear 15 is meshed with one of the fan-shaped teeth 18 for transmission, and the other fan-shaped teeth 18 is meshed with the transfer gear 16. Through the setting of the transfer gear 16, the driving force directions of the two driving swing arms 13 can be guaranteed to be consistent; the end of the driving swing arm 13 away from the fan-shaped substrate is provided with a driving base 19, and the driving hole 14 is obliquely arranged on the driving base 19. The driving holes 14 on the two driving swing arms 13 are symmetrically arranged, and the rotating shaft of the driving swing arm 13 is located between the fan-shaped substrate and the driving base 19. The two driving swing arms 13 can swing in the same direction under the meshing transmission with the main driving gear 15 and the transfer gear 16 on the corresponding side.

[0030] In order to realize the function of swinging and translating the mounting shell 2, guide holes 20 are respectively provided at the positions of the top surface of the fixing seat 1 and the driving holes 14 corresponding to the positions along the width direction of the fixing seat 1, and the guide holes 20 and the driving holes 14 are arranged to intersect, and a driving shaft 21 is provided on the top surface of the mounting shell 2, and the driving shaft 21 is sequentially passed through the guide holes 20 and the driving holes 14. When the two driving swing arms 13 swing in the same direction, the force exerted on the driving shafts 21 by the driving holes 14 causes the driving shafts 21 on both sides to move in the same direction along the guide holes 20, thereby causing the mounting shell 2 to move synchronously. Generally, in order to allow the mounting shell 2 to have a certain displacement space, the mounting shell 2 is relatively close to one of the side walls in the length direction of the fixing seat 1 in the initial state, and moves toward the other side wall in the length direction of the fixing seat 1 when displacement occurs. In addition, in this embodiment, the gear meshing transmission structure is adopted, which can effectively reduce the impact noise between parts and also make the synchronization effect relatively better.

[0031] Reference Figure 4 , 5 In order to reduce or avoid the movement of doors and windows due to wind when the doors and windows are forgotten to be locked, in this embodiment, a brake assembly is arranged between the mounting outer shell 2 and the mounting inner shell 3, and the brake assembly cooperates with the fixing seat 1 and the brake roller 4.

[0032] Among them, the brake stop assembly includes a mounting seat 22 for installing the brake pad, a mounting shaft 23, and a spring 24. A mounting groove for installing the mounting seat 22 is provided on the inner wall of the mounting inner shell 3 and at a position close to the edge of the roller 4. The mounting shaft 23 is installed in the middle of the end surface of the mounting seat 22 away from the roller 4. The other end of the mounting shaft 23 is penetrated through the mounting inner shell 3 and the mounting outer shell 2 and then topped on the inner wall of the fixing seat 1. The spring 24 is sleeved on the mounting shaft 23 between the mounting outer shell 2 and the fixing seat 1.

[0033] Since the height adjustment function is provided between the mounting inner shell 3 and the mounting outer shell 2, in order to synchronously adapt to the function, in this embodiment, a through hole 25 for the mounting shaft 23 to pass through is provided on the mounting inner shell 3, and a strip hole 26 for the mounting shaft 23 to pass through is obliquely provided on the mounting outer shell 2. The oblique direction and angle of the strip hole 26 are the same as those of the strip adjustment hole 6. In this way, when the height is adjusted, the brake assembly can also achieve synchronous displacement. In order to release the brake stop state, the brake assembly installed on the mounting seat 22 can be moved synchronously. The wheel plate no longer brakes the roller 4, and a mounting groove 27 connected to the strip hole 26 can be provided at the mounting shell 2 at the strip hole 26, and a spring support 28 is slidably installed in the mounting groove 27. A spring seat 29 is provided at the end of the mounting shaft 23 that is topped on the fixed seat 1, and the spring 24 is sleeved on the mounting shaft 23 between the spring support 28 and the spring seat 29. A brake pressure plate 30 is provided on one side wall in the longitudinal direction of the fixed seat 1, and the end face of the spring seat 29 away from the mounting shaft 23 is pressed against the brake pressure plate 30.

[0034] When the mounting shell 2 is in the initial state, since the mounting shell 2 is close to one side of the brake pressure plate 30, the brake pressure plate 30 is against the spring seat 29, and then the mounting shaft 23 is pressed toward the roller 4, so that the brake pad installed on the mounting seat 22 and the roller 4 are in a brake state. In this way, even if you forget to lock the door, since this brake state is always maintained here, the displacement of the door and window due to other external forces can be reduced or avoided. When the door and window need to be moved, the mounting shell 2 is displaced in the direction away from the brake pressure plate 30, so that the spring seat 29 and the brake pressure plate 30 are released from the resistance or contact state. Under the action of the spring 24, the brake pad is moved away from the roller 4, so that the roller 4 can rotate normally.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
