For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] like Figures 1 to 4As shown, an adjustable guide wheel mechanism of an embodiment of the utility model includes a connecting seat 100, a shell 200, a lifting module 300, a guide wheel 400 and a rotating module 500; wherein the shell 200 is arranged above the connecting seat 100, the lifting module 300 is arranged on the inner side of the shell 200, and the guide wheel 400 is arranged on the lifting module 300; the rotating module 500 is arranged on the connecting seat 100, and the rotating module 500 is connected to the shell 200.

[0047] In actual use, the lifting module 300 drives the guide wheel 400 to lift vertically perpendicular to the connecting seat 100, and then adjusts the distance between the guide wheel 400 and the connecting seat 100 to adjust the height of the guide wheel 400. The rotating module 500 drives the housing 200 to rotate, so as to drive the guide wheel 400 to rotate and adjust the lateral track of the guide wheel 400. Through the above operation, the height and lateral track of the guide wheel 400 are adjusted to adapt to push-pull profiles of different sizes, greatly improving the adaptability of the product.

[0048] In some embodiments, the lifting module 300 includes a first lifting component 31 and a second lifting component 32. The first lifting component 31 is disposed in the shell 200, and the second lifting component 32 is disposed at the end of the first lifting component 31 away from the shell 200. The guide wheel 400 is rotatably connected to the end of the second lifting component 32 away from the first lifting component 31; the first lifting component 31 is used to drive the second lifting component 32 to lift vertically, and the second lifting component 32 is used to drive the guide wheel 400 to lift vertically.

[0049] When the height of the guide wheel 400 needs to be adjusted, Figure 6 As shown, the height of the guide wheel 400 can be adjusted by the second lifting assembly 32, as shown in FIG. Figure 5 As shown, the height of the second lifting assembly 32 can be adjusted by the first lifting assembly 31. When the second lifting assembly 32 is lifted or lowered perpendicular to the connecting seat 100, the guide wheel 400 is lifted or lowered synchronously. Through the two-level adjustment of the first lifting assembly 31 and the second lifting assembly 32, the guide wheel 400 has a larger range of height adjustment space.

[0050] In this embodiment, if Figure 2 and Figure 3 As shown, the first lifting assembly 31 includes a fixing member 311, a first adjusting screw 312 and a movable plate 313. The fixing member 311 is fixed to the inner side of the housing 200, and the movable plate 313 is arranged at the lower end of the fixing member 311; a screw hole 3132 is arranged on the movable plate 313, and the lower end of the first adjusting screw 312 vertically penetrates the fixing member 311 and is connected to the threaded hole 3132; the second lifting assembly 32 is fixed to the upper end of the movable plate 313.

[0051] The fixing member 311 is fixedly connected to the housing 200. When the first adjusting screw 312 rotates, the fixing member 311 does not move synchronously with the first adjusting screw 312. Figure 5 As shown, when the first adjusting screw 312 is twisted counterclockwise, the movable plate 313 moves downward along the length direction of the first adjusting screw 312 under the action of the thread, shortening the distance between the guide wheel 400 and the connecting seat 100 and lowering the height of the guide wheel 400; conversely, Figure 5 As shown, when the first adjusting screw 312 is twisted clockwise, the movable plate 313 moves up along the length direction of the first adjusting screw 312 under the action of the thread, thereby increasing the distance between the guide wheel 400 and the connecting seat 100 and increasing the height of the guide wheel 400.

[0052] Specifically, the first lifting assembly 31 also includes an elastic member 314, the upper end of which is fixedly connected to the lower end surface of the movable plate 313, and the lower end of which is in contact with the connecting seat 100; in this embodiment, the elastic member 314 is a spring, and two groups are provided, and the two groups of elastic members 314 are symmetrically distributed at the lower end of the movable plate 313. The spring is squeezed to generate strong elasticity to keep the adjustment plate in a balanced state, thereby achieving height adjustment. Furthermore, for the spring, a spring seat 315 is provided on the lower end surface of the movable plate 313, and the elastic member 314 is fixedly connected to the spring seat 315 to prevent the spring from loosening.

[0053] In some embodiments, the housing 200 is provided with an assembly hole 21 , two assembly holes 21 are provided and are respectively arranged on two opposite surfaces of the housing 200 , and the fixing member 311 is fixedly connected to the housing 200 through the assembly holes 21 .

[0054] In some embodiments, the second lifting assembly 32 includes a first telescopic rod 321, a second telescopic rod 322, a third telescopic rod 323, a first elastic blocking piece 324, a second elastic blocking piece 325, and a fixing screw 326; one end of the second telescopic rod 322 is connected to the first telescopic rod 321 through the first elastic blocking piece 324, and the other end of the second telescopic rod 322 is connected to the third telescopic rod 323 through the second elastic blocking piece 325; the guide wheel 400 is arranged at the end of the first telescopic rod 321 away from the second telescopic rod 322. In order to realize the connection between the third telescopic rod 323 and the movable plate 313, a connecting hole 3131 is arranged on the movable plate 313, and the end of the third telescopic rod 323 away from the second telescopic rod 322 is connected to the connecting hole 3131 through the fixing screw 326. The guide wheel 400 is arranged at the end of the first telescopic rod 321 away from the second telescopic rod 322.

[0055] Since the first telescopic rod 321 is connected to the second telescopic rod 322 via the first elastic blocking piece 324, the third telescopic rod 323 is connected to the third telescopic rod 323 via the second elastic blocking piece 325. Figure 6 As shown, when the distance between the guide wheel 400 and the connection seat 100 needs to be increased, when the guide wheel 400 is pulled along the length direction of the first telescopic rod 321, the first telescopic rod 321 can be extended along the second telescopic rod 322, and the second telescopic rod 322 can be extended along the third telescopic rod 323, so that the distance between the guide wheel 400 and the connection seat 100 is increased. Conversely, when the distance between the guide wheel 400 and the connection seat 100 needs to be reduced, the guide wheel 400 is pushed along the length direction of the first telescopic rod 321, the first telescopic rod 321 will retract along the second telescopic rod 322, and the second telescopic rod 322 will retract along the third telescopic rod 323, so that the distance between the guide wheel 400 and the connection seat 100 is reduced. The above two operations realize the second lifting assembly 32 to adjust the height of the guide wheel 400.

[0056] In this embodiment, the rotating module 500 includes a second adjusting screw 51, a slide plate 52, a gear 53 and a connecting shaft 54; one end of the second adjusting screw 51 is threadedly connected to the slide plate 52; the slide plate 52 is provided with a bar tooth 521, and the gear 53 is meshed with the bar tooth 521; the gear 53 is provided with a center hole 531; during assembly, the connecting shaft 54 ​​passes through the center hole 531, and the upper end of the connecting shaft 54 ​​is connected to the shell 200 to achieve a fixed connection between the gear 53 and the shell 200.

[0057] In practical applications, such as Figure 7 As shown, when the lateral track of the guide wheel 400 needs to be adjusted, the second adjustment screw 51 is rotated, and the slide plate 52 moves along the length direction of the connecting seat 100 under the action of the thread; since the gear 53 and the bar teeth 521 are meshed with each other, the gear 53 rotates with the sliding of the slide plate 52; when the gear 53 rotates, the housing 200 rotates synchronously. Since the guide wheel 400 is fixed on the lifting module 300, and the lifting module 300 is fixed in the housing 200, when the housing 200 rotates, the guide wheel 400 rotates accordingly to adjust the lateral track of the guide wheel 400.

[0058] Specifically, the lower end surface of the shell 200 is provided with a plug-in column 22, and the gear 53 is provided with a socket 532. As shown in the figure, after the shell 200 is connected to the connecting seat 100, the plug-in column 22 is plugged into the socket 532, and the socket 532 deviates from the central axis of the gear 53. When the gear 53 rotates, the shell 200 will rotate synchronously therewith.

[0059] Specifically, a limiting column 11 is provided on the side of the connecting seat 100 facing the slide plate 52 , and a sliding groove 522 is provided on the slide plate 52 . The limiting column 11 is always slidably connected in the sliding groove 522 to limit the slide plate 52 from sliding along the length direction of the connecting seat 100 .

[0060] Compared with the prior art, the adjustable guide wheel mechanism involved in the utility model is provided with a connecting seat 100, a shell 200, a lifting module 300, a guide wheel 400 and a rotating module 500; the connecting seat 100 is used to assemble the guide wheel 400 to the sliding door and window profile; the lifting module 300 drives the guide wheel 400 to lift and lower to adjust the vertical height. In addition, the lifting module 300 includes a first lifting component 31 and a second lifting component 32, which can realize two-level lifting and lowering, and the adjustment range is larger; the rotating module 500 drives the guide wheel 400 to rotate to adjust the lateral wheelbase; thereby, the guide wheel 400 can be applied to a variety of sliding door profile slots of different specifications, which greatly improves the adaptability of the product.

[0061] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
