[0003] Chinese patent CN205116691 U discloses a portable stair tread, including a U-shaped handrail. The inner side of the U-shaped handrail has symmetrical fixing holes. One end of the tread has a pivot that mates with the fixing holes, and the other side has a threaded through hole. The tread is positioned between the two side walls of the U-shaped handrail. A support rod is bolted to the outer side of the U-shaped handrail, forming a V-shape with the side walls. A fixing rod is hinged to the support rod. A fixing plate is positioned between the two fixing rods, and the fixing plate has a threaded hole that mates with the threaded through hole. A hook is provided at the movable end of the fixing rod, and a fixing ring mates with the hook is provided on the lowest tread. This stair tread utilizes a detachable support rod and U-shaped handrail, with a rotatable tread positioned between the side walls of the U-shaped handrail. The tread is fixed in place by engaging with the fixing rod hinged to the support rod.

[0004] The stair treads in the aforementioned patent documents can only unfold at a fixed angle during use, making the angle of the stair treads fixed and unable to be adjusted. Therefore, a modular escalator for prefabricated housing decoration that is easy to adjust in angle is proposed. Utility Model Content

[0005] To address the aforementioned problems, a modular escalator for prefabricated housing decoration with adjustable angles is provided. A flexible metal rope pulls a pawl, allowing one end of the pawl to separate from the ratchet. Then, pushing either the first or second folding section allows the top of the second folding section to rotate along the central axis of the mounting shaft, adjusting the angle between the first and second folding sections. Releasing the flexible metal rope then activates a tension spring on one side of the pawl, pulling it closer to the ratchet until one end engages with it. This achieves pawl-limited positioning of the ratchet, solving the problem of the escalator only unfolding at a fixed angle.

[0006] To address the existing technical problems, this application provides a modular escalator for prefabricated house decoration that is easy to adjust the angle, including a first folding part, a horizontally arranged mounting shaft fixed to the top of the first folding part, and a second folding part that can rotate along its central axis installed on the outside of the mounting shaft;

[0007] A mounting groove is provided on one side of the top of the second folding part, and a ratchet is provided inside the mounting groove. The ratchet is fixed on the mounting shaft.

[0008] The mounting groove is also provided with a pawl for limiting the ratchet.

[0009] The mounting groove is equipped with a tension spring for pulling the pawl to reset;

[0010] One side of the pawl is provided with a flexible metal cord that allows it to separate from the ratchet.

[0011] As one technical solution of this application, a fixing rod for installing a tension spring is fixed inside the mounting groove near the ratchet; a mounting hole is provided on one side of the pawl, and the end of the tension spring away from the fixing rod is installed in the mounting hole.

[0012] As one technical solution of this application, a first mounting rod is fixed inside the mounting groove near the bottom of the fixed rod;

[0013] One end of the pawl is provided with a tension spring seat that can be mounted on the first mounting rod.

[0014] As one technical solution of this application, a second mounting rod is provided on the other side of the pawl; the top end of the flexible metal pull rope is mounted on the second mounting rod;

[0015] The flexible metal pull cord can extend from inside the mounting groove to the outside of the second fold.

[0016] As one technical solution of this application, the bottom end of the flexible metal pull rope is provided with a handle that is easy to grip.

[0017] As one technical solution of this application, a limiting member is installed on the side of the mounting shaft near the ratchet, and the limiting member is used to prevent the ratchet from falling off the mounting shaft.

[0018] As a technical solution of this application, a support mechanism is provided at the bottom of both the first folding part and the second folding part, and the support mechanism can prevent the first folding part and the second folding part from tilting to the side.

[0019] The support mechanism includes a support frame with its top hinged to the first fold and the second fold, and a sliding frame that can slide along its central axis is mounted on the outside of the support frame.

[0020] As one technical solution of this application, a threaded hole is provided on the top of one side of the sliding frame, and a rotatable fastener is installed inside the threaded hole.

[0021] The advantages of this utility model compared to the prior art are:

[0022] This application utilizes a flexible metal cable to pull a pawl, allowing one end of the pawl to separate from the ratchet. Then, pushing the first or second folding section allows the top of the second folding section to rotate along the central axis of the mounting shaft, adjusting the angle between the first and second folding sections. The flexible metal cable is then released; at this point, a tension spring on one side of the pawl pulls the pawl closer to the ratchet until one end of the pawl engages with the ratchet. This achieves the pawl's limitation of the ratchet, solving the problem that the escalator can only unfold at a fixed angle. Attached Figure Description

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figures 1-7 As shown, a modular escalator for prefabricated house decoration with adjustable angle includes a first folding part 1, a horizontally arranged mounting shaft 4 fixed to the top of the first folding part 1, and a second folding part 2 that can rotate along its central axis installed on the outside of the mounting shaft 4.

[0033] The second folding part 2 has a mounting groove 21 on one side of its top. A ratchet 41 is provided inside the mounting groove 21 and is fixed on the mounting shaft 4.

[0034] The mounting slot 21 is also equipped with a pawl 5 for limiting the ratchet 41;

[0035] The mounting slot 21 is equipped with a tension spring 6 for pulling the pawl 5 to reset;

[0036] A flexible metal cord 7 is provided on one side of the pawl 5 to separate it from the ratchet 41.

[0037] When the escalator unfolds, the flexible metal cable 7 is first pulled, causing the pawl 5 to move and disengage from the ratchet 41. Then, either the first folding section 1 or the second folding section 2 is pushed, allowing the top of the second folding section 2 to rotate along the central axis of the mounting shaft 4, thus adjusting the angle between the first folding section 1 and the second folding section 2. To prevent the angle between the first folding section 1 and the second folding section 2 from increasing during use, the flexible metal cable 7 is loosened. At this point, the tension spring 6 on one side of the pawl 5 pulls the pawl 5 closer to the ratchet 41 until one end of the pawl 5 engages with the ratchet 41. At this point, the angle between the first folding section 1 and the second folding section 2 can only decrease and cannot increase further, effectively preventing the escalator from slipping during use.

[0038] See Figure 6 and Figure 7 As shown, a fixing rod 23 for mounting the tension spring 6 is fixed inside the mounting groove 21 near the ratchet 41; a mounting hole 51 is provided on one side of the pawl 5, and the end of the tension spring 6 away from the fixing rod 23 is mounted on the mounting hole 51.

[0039] One end of the tension spring 6 is mounted on the fixed rod 23, and the other end of the tension spring 6 away from the fixed rod 23 is mounted on the mounting hole 51. When the flexible metal pull rope 7 stops pulling the pawl 5, the pulling force of the tension spring 6 will pull the pawl 5 back to its original position through the mounting hole 51.

[0040] See Figure 6 and Figure 7 As shown, a first mounting rod 22 is fixed inside the mounting groove 21 near the bottom of the fixing rod 23;

[0041] One end of the pawl 5 is provided with a tension spring seat 52 that can be installed on the first mounting rod 22.

[0042] To ensure the stability of the pawl 5, a tension spring seat 52 is provided at one end of the pawl 5, and then the tension spring seat 52 is installed on the first mounting rod 22, so that the pawl 5 can rotate along the central axis of the first mounting rod 22 through the tension spring seat 52.

[0043] See Figure 6 and Figure 7 As shown, a second mounting rod 53 is provided on the other side of the pawl 5; the top end of the flexible metal pull rope 7 is mounted on the second mounting rod 53;

[0044] The flexible metal pull cord 7 can extend from inside the mounting groove 21 to the outside of the second fold 2.

[0045] To ensure an effective connection between the flexible metal pull rope 7 and the pawl 5, the top end of the flexible metal pull rope 7 is fixed to the second mounting rod 53 on the other side of the pawl 5, and the bottom end of the flexible metal pull rope 7 extends out of the mounting groove 21. When the flexible metal pull rope 7 is pulled, it can drive the pawl 5 to rotate along the central axis of the first mounting rod 22 via the second mounting rod 53, allowing the end of the pawl 5 away from the first mounting rod 22 to separate from the ratchet 41.

[0046] See Figure 7 As shown, the bottom end of the flexible metal pull rope 7 is provided with a handle 71 for easy gripping.

[0047] To facilitate gripping of the flexible metal pull rope 7, a handle 71 is provided at the bottom of the flexible metal pull rope 7. When it is necessary to pull the flexible metal pull rope 7, simply hold the handle 71 to operate, avoiding injury to the user's palm when pulling the flexible metal pull rope 7.

[0048] See Figure 7 As shown, a limiting member 42 is installed on the side of the mounting shaft 4 near the ratchet 41. The limiting member 42 is used to prevent the ratchet 41 from falling off the mounting shaft 4.

[0049] To ensure the stability of the ratchet 41, a limiting member 42 is installed on the outside of the shaft 4 on one side of the ratchet 41, so that the limiting member 42 fixes the position of the ratchet 41 and prevents the ratchet 41 from shifting.

[0050] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a support mechanism 3 is provided at the bottom of both the first folding part 1 and the second folding part 2. The support mechanism 3 can prevent the first folding part 1 and the second folding part 2 from tilting to the side.

[0051] The support mechanism 3 includes a support frame 31 with its top hinged to the first folding part 1 and the second folding part 2, and a sliding frame 33 that can slide along its central axis is mounted on the outside of the support frame 31.

[0052] To prevent the escalator from tipping over during use, unfoldable support mechanisms 3 are installed on one side of the bottom of the first folding section 1 and the second folding section 2, respectively. When unfolded, the support mechanisms 3 can support both sides of the first folding section 1 and the second folding section 2. To ensure effective support, the top of the support frame 31 is hinged to both sides of the bottom of the first folding section 1 and the second folding section 2, allowing the support frame 31 to unfold. By installing a sliding frame 33 on the support frame 31, when the support frame 31 unfolds, the sliding frame 33 moves downward along the central axis of the support frame 31, increasing the overall length of the support mechanism 3, thus facilitating effective support for the first folding section 1 and the second folding section 2.

[0053] See Figure 5 As shown, a threaded hole 34 is provided on the top of one side of the sliding bracket 33, and a rotatable fastener 32 is installed inside the threaded hole 34.

[0054] To ensure the stability of the sliding frame 33, a threaded hole 34 is provided at the top of one side of the sliding frame 33, and then a fastener 32 is installed inside the threaded hole 34. When the fastener 32 is rotated, it can move along the central axis of the threaded hole 34. At this time, the mounting end of the fastener 32 will approach or move away from the surface of the support frame 31. When one end of the fastener 32 approaches the support frame 31 and contacts the surface of the support frame 31, the fastener 32 can fix the sliding frame 33, effectively ensuring the stability of the sliding frame 33. When the mounting end of the fastener 32 moves away from the support frame 31, the sliding frame 33 can be extended or retracted.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
