[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0045] Figure 1The application discloses a lateral guide wheel device applied to a window cleaning machine.

[0046] In detail, please refer to Figures 2 to 5 , Figure 2 The application discloses a lateral guide wheel device applied to a window cleaning machine. Figure 3 The application discloses a lateral guide wheel device applied to a window cleaning machine. Figure 4 The application discloses a lateral guide wheel device applied to a window cleaning machine. Figure 5 The application discloses a lateral guide wheel device applied to a window cleaning machine. The lateral guide wheel device comprises a mounting base, a lateral guide wheel support, an adjusting bolt and a lateral guide wheel. The mounting base is connected to the inner side of the inner lateral arm pipe and is located at the position of the lateral guide wheel hole. The lateral guide wheel support has a guide wheel mounting portion, an adjusting portion and a rotating fulcrum portion. The lateral guide wheel support is hinged to the mounting base through the rotating fulcrum portion. The adjusting bolt is connected to the mounting base and corresponds to the adjusting portion. The lateral guide wheel is rotatably connected to the guide wheel mounting portion. Part of the lateral guide wheel is located on the inner side of the inner lateral arm pipe, and the other part of the lateral guide wheel is located between the inner lateral arm pipe and the outer lateral arm pipe.

[0047] In the application, the adjusting bolt can push out or retract the adjusting portion, so that the lateral guide wheel support drives the lateral guide wheel to rotate, thereby conveniently adjusting the gap size between the lateral guide wheel and the outer lateral arm pipe.

[0048] It is worth mentioning that the guide wheel mounting portion, the adjusting portion and the rotating fulcrum portion are in a triangular distribution, so that the lateral guide wheel support rotates along the rotating fulcrum portion.

[0049] Furthermore, the guide wheel mounting portion 41 includes: a first through hole 411 and a guide wheel shaft 412, the first through hole 411 is located at the first end of the lateral guide wheel bracket 4; the guide wheel shaft 412 is passed through the first through hole 411, and the lateral guide wheel 6 is sleeved on the guide wheel shaft 412 through a copper sleeve 413; the guide wheel shaft 412 is connected to the lateral guide wheel bracket 4 through a connecting cover plate 414 and a fixing screw 415.

[0050] In the embodiments of this application, a copper sleeve, also known as a copper bushing or copper bearing, is a commonly used mechanical component primarily used to reduce friction and wear between rotating or sliding parts. Copper sleeves are typically made of copper alloys, such as brass and bronze. These materials have excellent wear resistance, corrosion resistance, and self-lubrication properties, making them suitable for a variety of working environments.

[0051] Specifically, the rotating fulcrum portion 43 includes: a second through hole 431 and a fulcrum bolt 432, the second through hole 431 is located at the second end of the lateral guide wheel bracket 4; the fulcrum bolt 432 passes through the second through hole 431 and the third through hole 31 of the mounting seat 3 in sequence, and the fulcrum bolt 432 is detachably connected to the mounting seat 3 through a locking nut 433; a safety pin 434 is also provided on the fulcrum bolt 432, and the safety pin 434 is located on the outside of the locking nut 433.

[0052] In the embodiment of the present application, the fulcrum bolt 432 acts as a rotating shaft. Preferably, a copper sleeve is also provided on the outer periphery of the fulcrum bolt 432, that is, at the fitting position between the fulcrum bolt 432 and the second through hole 431, to improve the smoothness of the rotation.

[0053] In the embodiment of the present application, the safety pin 434 is used to prevent the fulcrum bolt 432 from falling, thereby improving the safety and stability of the entire device.

[0054] More specifically, the adjustment portion 42 includes a baffle 421 located at the third end of the lateral guide wheel bracket 4; wherein the adjustment bolt 5 is passed through the fourth through hole 32 of the mounting seat 3, and the ejection or retraction of the baffle 421 is adjusted by the adjustment nut 51.

[0055] In the embodiment of the present application, there is no limitation on the connection method between the mounting seat 3 and the inner cross arm tube 1, and at least one of welding, bolt connection, riveting, and bonding is used.

[0056] Next, the working principle of the lateral guide wheel device applied to the window cleaning machine involved in the embodiment of the present invention is described.

[0057] In one example, the inner cross arm tube has four lateral guide wheel holes, and the four lateral guide wheel holes are correspondingly installed with four lateral guide wheel devices used in the window cleaning machine; Figure 6A schematic diagram showing a side guide wheel of a side guide wheel device applied to a window cleaning machine provided by an exemplary embodiment of the present invention in an ejected state is shown. Figure 7 A schematic diagram showing a side guide wheel of a side guide wheel device applied to a window cleaning machine provided by an exemplary embodiment of the present invention in a retracted state is shown.

[0058] Insert the inner cross arm tube with the pre-installed lateral guide wheel into the outer cross arm tube. At this time, the lateral guide wheel is in the retracted state. Rotate the adjusting bolt to push it forward until it hits the baffle of the lateral guide wheel bracket.

[0059] As the adjusting bolt is continuously pushed out, the lateral guide wheel bracket rotates around the fulcrum bolt. When the gap between the lateral guide wheel and the inner wall of the outer cross arm tube gradually decreases to the gap required for the actual working condition, tighten the adjusting nut to keep the lateral guide wheel in the current position.

[0060] The clearances between the four lateral guide wheels and the inner wall of the outer cross arm tube can be adjusted simultaneously to achieve a uniform clearance. If the lateral guide wheel needs to be removed from the inner cross arm tube later, the safety pin can be pulled out, the locking nut can be unscrewed, and the fulcrum bolt can be removed, and the lateral guide wheel bracket and the lateral guide wheel can be removed from the inner cross arm tube.

[0061] In summary, the present invention comprises a mounting seat, a lateral guide wheel bracket, an adjustment bolt, and a lateral guide wheel. The mounting seat is connected to the inner side of the inner cross arm tube and is located at the position of the lateral guide wheel hole. The lateral guide wheel bracket comprises a guide wheel mounting portion, an adjustment portion, and a rotation fulcrum portion. The lateral guide wheel bracket is hingedly connected to the mounting seat via the rotation fulcrum portion. The adjustment bolt is connected to the mounting seat and corresponds to the adjustment portion. The lateral guide wheel is rotatably connected to the guide wheel mounting portion. A portion of the lateral guide wheel is located on the inner side of the inner cross arm tube, and another portion of the lateral guide wheel is located between the inner cross arm tube and the outer cross arm tube. In this manner, the gap between the lateral guide wheel and the inner wall of the outer cross arm tube can be easily adjusted, and disassembly and maintenance are facilitated. This not only improves work efficiency, but also reduces maintenance costs and extends the service life of the equipment. This is of great significance for improving the overall performance and operational safety of the window cleaning machine.

[0062] In the embodiments disclosed in this utility model, the terms "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; "connected" can mean a direct connection or an indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the embodiments disclosed in this utility model based on specific circumstances.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
