[0038] Please refer to Figure 1 and Figure 2 In a preferred embodiment of the present invention, a bathroom exterior wall climbing frame assembly is provided, which is used to be fixedly installed on a wall 100 of the bathroom exterior wall, and includes an extension seat 200, a climbing frame mounting seat 300, a climbing frame 400, a movable support rod 500, a stable support structure and a reset structure.

[0039] The rear end of the extension seat 200 is fixed to the wall 100, so that the climbing frame 400 can avoid the floating board 110 in the upper and lower directions of the wall 100 of the outer wall of the bathroom.

[0040] The climbing frame mounting seat 300 is fixedly connected to the front end of the extension seat 200. The front end of the climbing frame mounting seat 300 is installed with a positioning guide wheel 310, and the positioning guide wheels 310 are arranged at intervals on the left and right.

[0041] Guide grooves 410 for the positioning guide wheels 310 to be embedded in are provided on the left and right sides of the climbing frame 400, and a vertically arranged crossbar 420 is provided in the middle of the climbing frame 400. The positioning guide wheels 310 on the left and right sides are embedded in the guide grooves 410 on both sides of the climbing frame 400, thereby limiting the climbing frame 400 and preventing the climbing frame 400 from moving horizontally away from the positioning guide wheels 310. This guides the climbing frame 400 during lifting and lowering, making its lifting movement stable and reducing lifting friction resistance. It is understood that the width of the guide groove 410 can be slightly larger than the positioning guide wheel 310, such as greater than 1mm-10mm, so that when lifting and lowering, the positioning guide wheel 310 will roll in contact with one side of the guide groove 410 and not in contact with the other side.

[0042] One end of the movable support rod 500 is hinged to the climbing frame mounting base 300, and the other end is provided with a rod slot 510. The rod slot 510 is used to cooperate with one of the cross bars 420 to support the cross bar 420, thereby supporting the entire climbing frame 400. The movable support rod 500 has a supporting state and an avoiding state. In the supporting state, the rod slot 510 of the movable support rod 500 cooperates with one of the cross bars 420 to support the cross bar 420. In the avoiding state, the movable support rod 500 avoids the path of the cross bar 420's lifting and lowering movement.

[0043] The stable support structure is used to stabilize the movable support rod 500 in a supporting state.

[0044] The reset structure is used to apply a force to the movable support rod 500 in the avoidance state to move toward the support state, so that the movable support rod 500 in the avoidance state can be reset to the support state without being subject to other additional forces, making it convenient for the climbing frame 400 to be adjusted to the appropriate position and then released to complete the support.

[0045] The present invention provides a bathroom exterior wall climbing frame assembly. The guide grooves 410 on the left and right sides of the climbing frame 400 engage with the positioning guide wheels 310 at the front end of the climbing frame mounting base 300, enabling smooth movement of the climbing frame 400 during lifting and lowering. Adjustment of the position is more convenient and quick, reducing the tedious adjustments associated with conventional climbing frames. The movable support rod 500, when in the avoidance position, avoids the lifting path of the crossbar 420, providing ample space for the climbing frame to be raised and lowered, ensuring that the climbing frame is not obstructed by the movable support rod 500 during adjustment. In the support position, the rod grooves 510 of the movable support rod 500 cooperate with the crossbar 420 to provide stable support for the climbing frame. The stabilizing support structure further enhances the stability of the movable support rod 500 in the support position, ensuring the stability of the climbing frame once installed and protecting the safety of construction workers and equipment. A reset structure applies a force to the movable support rod 500 in the avoidance position, allowing it to automatically return to the support position after the climbing frame is raised and lowered. This structure also stabilizes the movable support rod 500 in the support position. The rear end of the extension seat 200 is fixed to the wall 100 of the bathroom exterior wall, providing a stable installation foundation for the climbing frame mounting seat 300.

[0046] Reference Figure 4 、 Figure 5 and Figure 6 In some embodiments of the present invention, the climbing frame mounting base 300 has two side panels 320 spaced apart from each other. The rear ends of the two side panels 320 are fixedly connected via an end panel 330. The end panel 330 is provided with corresponding holes and is fixed to the front end of the extension base 200 via screws and nuts. A hinge shaft 321 is installed on the two side panels 320 for hinged installation of the movable support rod 500. The hinge shaft 321 passes through the two side panels 320. The front ends of the two side panels 320 are connected to a guide wheel bracket 340, and the positioning guide wheel 310 is mounted on the guide wheel bracket 340. Specifically, the front ends of the two side panels 320 are provided with an outwardly extending connecting plate. The guide wheel bracket 340 is an L-shaped plate. One side of the guide wheel bracket 340 is in contact with the connecting plate and is fixed via fasteners, while the other side is used to mount the positioning guide wheel 310. This achieves the installation and fixation of the positioning guide wheel 310.

[0047] Reference Figure 3 and Figure 6In some embodiments of the present invention, the front end surface of the extension seat 200 is provided with a support block 220 extending forward below the end plate 330, and the front end of the support block 220 is provided with a limit block 230 extending upward. The front end surface of the extension seat 200, the support block 220, and the limit block 230 define a card slot 231 with an upward opening, and the bottom of the end plate 330 is embedded in the card slot 231. Therefore, during installation, the card slot 231 supports and limits the end plate 330, which plays a pre-support and positioning effect, facilitates the subsequent hole alignment and installation of fasteners, and improves installation convenience.

[0048] Reference Figure 4 In some embodiments of the present invention, the stabilizing support structure comprises limit rods 520 connected to the left and right sides of the movable support rod 500 and extending horizontally. The limit rods 520 and the movable support rod 500 can be connected and fixed by means of threaded connection, fasteners, or welding. The climbing frame 400 includes vertical rods 430 spaced apart on the left and right sides. The ends of the horizontal rod 420 are respectively connected and fixed to the vertical rods 430 on both sides. The guide grooves 410 are formed on the back-facing sides of the two vertical rods 430. In the supporting state, the limit rods 520 and the vertical rods 430 are abutted to prevent the end of the movable support rod 500 away from the hinge position from rotating downward. It can be understood that due to the installation position, the movable support rod 500 will be arranged at the rear side of the climbing frame 100, so when the movable support rod 500 is in the supporting state, it is in an inclined supporting state. In addition, the one end of the movable support rod 500 supporting the horizontal rod 420 is subjected to the gravity of the climbing frame 400 and is hingedly installed. The one end of the movable support rod 500 supporting the horizontal rod 420 has a tendency to rotate downward. At this time, the limit rod 520 and the vertical rod 430 are offset, which can prevent the one end of the movable support rod 500 supporting the horizontal rod 420 from rotating downward, so that the movable support rod 500 is in the supporting state, and under the dual action of the gravity of the climbing frame 400 and the offset of the limit rod 520 and the vertical rod 430, the state of the movable support rod 500 is more stable, achieving a certain self-locking effect.

[0049] Reference Figure 4 and Figure 5In a further embodiment of the present invention, first connecting rings 530 are provided on both sides of the movable support rod 500, and second connecting rings 350 are provided on both sides of the movable support rod 500 on the climbing frame mounting base 300. The reset structure is a tension spring 540. The first connecting ring 530 is connected to the second connecting ring 350 on the corresponding side by a tension spring 540. The tension spring 540 is used to pull the movable support rod 500 in the avoidance state toward the support state. Specifically, the second connecting ring 350 is located in front of the hinge shaft 321. The tension spring 540 pulls the end of the movable support rod 500 provided with the rod groove 510 forward to move closer to the climbing frame 400, thereby pushing the movable support rod 500 in the avoidance state toward the support state. This makes it more convenient to adjust the position of the climbing frame 500 when it is raised. When the climbing frame 400 is in the process of rising, the cross bar 420 needs to pass over the movable support bar 500, and the cross bar 420 rises to automatically push the movable support bar 500 away, so that it automatically switches to the avoidance state. After the cross bar 420 passes over the movable support bar 500, due to the action of the tension spring 540, the tension spring 540 will pull the movable support bar 500 back to the limit bar 520 and the vertical bar 430, so that the movable support bar 500 can be adjusted. The rod 500 returns to the supporting state, and the rod groove 510 is aligned with the upper cross bar 420. If the height of the climbing frame 400 has been adjusted to the corresponding height, the climbing frame 400 is slowly lowered so that the cross bar 420 is embedded in the lower rod groove 510, completing the support after the height adjustment. The height adjustment is achieved without operating the movable support rod 500. By utilizing the hinged movement of the movable support rod 500, the reset function of the tension spring 540 and the limiting positioning function of the limit rod 520, the climbing frame 400 can freely rise to the required height. The rod groove 510 will be in a state of being aligned with the upper cross bar 420, and can receive the upper cross bar 420 for support. This makes it very convenient to adjust the height of the climbing frame 400. Even if the climbing frame 400 becomes loose during the ascent, the movable support rod 500 can catch the cross bar 420, and the ascent operation of the climbing frame 400 is also improved.

[0050] In a further embodiment of the present invention, embedded parts are further included, which are at least partially embedded in the wall 100 and are used to fix the extension seat 200 to the wall 100. It can be understood that the embedded parts are embedded in the wall 100 to provide a stable installation base for the extension seat 200 and improve the installation stability of the extension seat 200.

[0051] Reference Figure 2 、 Figure 4 and Figure 5In a further embodiment of the present invention, the embedded component is a base plate 600. Multiple connecting tubes 610 are provided on the rear surface of the base plate 600. The base plate 600 is also embedded in the outer wall of the wall 100. During subsequent exterior wall decoration, the base plate 600 can be covered with an exterior wall decorative layer or paint to ensure aesthetics. The connecting tube 610 is provided with a threaded hole 620 extending to the front surface of the base plate 600. The rear end of the threaded hole 620 is closed and aligned with the first through hole 210. A groove 630 is provided on the front surface of the base plate 600. The extension base 200 includes a rear connecting base 240 and a front connecting base 250. The rear end of the rear connecting base 240 is provided with an auxiliary positioning block 241 that fits into the groove 630. The auxiliary positioning block 241 fits into the groove 630, thereby providing a pre-positioning effect during installation of the rear connecting base 240 and facilitating screw installation after the first through hole is aligned with the threaded hole. The rear connecting base 240 is provided with a first through hole 210 corresponding to the threaded hole 620. The front connecting seat 250 is spaced in front of the rear connecting seat 240 and is fixedly connected to the rear connecting seat 240. The front connecting seat 250 is also fixedly connected to the climbing frame mounting seat 300. A screw 260 is internally threaded into the threaded hole 620. One end of the screw is threadedly connected to the threaded hole 620, and the other end extends out of the first through-hole 210 and is connected to the second fastening nut 261. The rear connecting seat 240 is clamped and fixed by the second fastening nut 261, thereby achieving the installation and fixation of the rear connecting seat 240. The combination of the connecting tube 610 and the screw 260 only needs to be embedded in the wall 100, without penetrating the wall 100, avoiding direct penetration damage to the bathroom exterior wall, ensuring the integrity of the bathroom interior wall, and preventing water seepage.

[0052] Specifically, the rear connecting seat 240 and the front connecting seat 250 are connected and fixed by connecting rods 270 at the corners. The rear connecting seat 240 and the front connecting seat 250 are both composed of a square frame and a square plate fixed to the square frame.

[0053] Reference Figure 2 and Figure 4In some embodiments of the present invention, a rear protrusion 640 is provided on the rear surface of the base plate 600 corresponding to the groove 630, with the rear end of the groove 630 extending into the rear protrusion 640. A hook groove 631 is provided on the rear side of the bottom wall of the groove 630, and a hook block 242 is provided on the rear bottom of the auxiliary positioning block 241 to engage with the hook groove 631. This further stabilizes the connection between the rear connecting seat 240 and the base plate 600, preventing it from loosening during installation and providing a stable foundation for the installation of the screw 260 and the second fastening nut 261. The overall height of the hook block 242 and the auxiliary positioning block 241 is less than the height of the front opening of the groove 630. The overall height of the hook block 242 and the auxiliary positioning block 241 is less than the height of the front opening of the groove 630. That is, during installation, the hook block 242 and the auxiliary positioning block 241 can be inserted into the front opening of the groove 630 and then lowered so that the hook block 242 engages with the hook groove 631, thereby achieving installation and avoiding structural interference. The front and rear side walls of the hook block 242 are respectively in contact with the front and rear side walls of the hook groove 631 , thereby further achieving a positioning effect. The bottom edge of the hook block 242 is chamfered to improve the smoothness of the hook block 242 being embedded in the hook groove 631 .

[0054] Reference Figure 2 In some embodiments of the present invention, the rear end of the connecting tube 610 is provided with an outwardly radially protruding expansion portion 650 , thereby improving the anchoring effect in the wall 100 and improving the installation stability of the connecting tube 610 .

[0055] Reference Figure 7 In some other embodiments of the present invention, a mounting hole is provided at the rear end of the extension base 200, that is, a mounting hole is provided on the rear connecting base 240. The embedded component is a stud 660. The stud 660 is partially embedded in the wall 100, and partially extends out of the wall 100 and is connected to a first fastening nut 661 through the mounting hole.
