The triangular support shaft 70 is provided with a hand-pull shaft through hole 73 that penetrates along the axial direction. The rear end of the hand-pull shaft 43 passes through the hand-pull shaft through hole 73. The side wall of the triangular support shaft 70 is provided with a wire groove 74 along the axial direction. The wires of the motor 30 and the wires of the electromagnet 42 extend out through the wire groove 74 respectively to discharge the wires outside.

[0047] The guide wheel 50 is rotatably sleeved on the triangular support shaft 70. Figures 14 to 16The guide wheel 50 includes a guide wheel body, the periphery of one end surface of the guide wheel body extends outward to form a peripheral wall, and a mounting cavity 51 for mounting a travel switch 80 is formed in the peripheral wall; a bearing mounting seat 52 is provided on the other end surface of the guide wheel body, a support shaft clearance hole 53 is provided in the middle of the bottom wall of the mounting seat 52, a gear ring 54 is formed at the periphery of the support shaft clearance hole 53 in the mounting cavity 51, the travel assembly 80 is mounted on the triangular support shaft 70 and its travel gear 81 is meshed with the gear ring 54 of the guide wheel 50; an annular recessed groove 55 is provided at the periphery of the gear ring 54 in the mounting cavity 51;

[0048] like Figure 5 As shown, the tubular motor is inserted into the reel 90, and the driving wheel 10 and the guide wheel 50 are riveted and fixed on the reel 90 respectively, so that the guide wheel 50 rotates synchronously with the driving wheel 10. When the driving wheel 10 rotates, the guide wheel 50 rotates synchronously, and the ring gear 54 is transmitted to the stroke assembly 80, thereby reaching the control points of the upper limit and the lower limit of the stroke.

[0049] The hand-pull seat 60 is installed at the rear end of the triangular support shaft 70, the rear end of the hand-pull shaft 43 passes through the hand-pull seat 60, the hand-pull sprocket wheel 61 of the hand-pull seat 60 is fixed to the rear end of the hand-pull shaft 43, and the hand-pull seat 60 is provided with a chain pressing plate 62 that can control the axial movement of the hand-pull shaft 43, and the hand-pull chain 63 is connected to the hand-pull sprocket wheel 61.

The triangular support shaft 70 forms a three-sided space to make room for assembly space and save materials.

[0052] like Fig.11 As shown, the hand-pulled shaft 43 is provided with a limiting step 431. After installation, the limiting step 431 is located between the electromagnet and the second triangular base of the support shaft, which can limit the sliding distance of the hand-pulled shaft 43 in the triangular support shaft 70.

[0053] In this embodiment, Figures 14 to 16 As shown, the guide wheel 50 is provided with four first process holes 56 on the peripheral wall for the tool for installing the stroke assembly 80 to pass through. The guide wheel 50 is provided with an annular recessed groove 55, which is convenient for punching rivet holes in the matching position between the reel and the guide wheel 50 to obtain a clearance space. If there is no recessed groove clearance space, the rivet head cannot be riveted. The guide wheel 50 is provided with a guide wheel cover assembly hole for assembling the guide wheel cover 120, as shown in FIG. Figures 17 to 19 As shown, the guide wheel cover 120 has an annular structure, and the guide wheel cover 120 is embedded in the annular recessed groove 55 of the guide wheel 50 to prevent particles, aluminum chips, and flying dust from falling between the guide wheel 50 ring gear 54 and the travel gear 81, thereby avoiding gear tooth damage or tooth skipping.

[0054] In this embodiment, the guide wheel 50 is provided with a gear ring 54 to form an integral body, so that the overall structure is more reliable and strong, and more stable during the transmission process, unlike the cumulative tolerance caused by the combination of multiple parts, and the transmission is more precise. When the reel rotates, it drives the guide wheel 50 to rotate synchronously, and the gear ring of the guide wheel 50 is a whole and also rotates together, thereby driving the travel gear 81 of the travel assembly 80 to rotate, and the entire travel transmission system operates together, thereby reaching the upper and lower limit control points of the travel. Compared with the traditional motor, which uses a gear in the output and then drives the travel assembly through the gear, it has a better effect.

[0055] The guide wheel 50 is provided with a bearing 130 for rotating the triangular support shaft 70, and the bearing mounting seat 52 of the guide wheel 50 is provided with two penetrating second process holes 57 for disassembling and assembling the bearing 130. During the assembly process, if the bearing 130 is placed unbalanced and not vertical, it will cause the bearing to be pressed into the center of the center, and it will also cause the internal structure of the bearing to deform and produce abnormal noise. When this happens, the two second process holes 57 must be used to adjust or disassemble it and re-press it.

[0056] The guide wheel 50 is also provided with a positioning step 58, and the positioning step 58 is used to position the iron sleeve 44 surrounding the brake device 40 to prevent dust and foreign matter from entering. The outer peripheral wall of the guide wheel 50 is provided with an inner diameter step 59 corresponding to the reel.

[0057] The above embodiments are only used to further illustrate the guide wheel structure of a tubular motor of the utility model, but the utility model is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model fall within the protection scope of the technical solution of the utility model.
