Furthermore, reference numerals and / or reference letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0032] refer to Figure 1-3 In one aspect, this utility model proposes a cycling trainer, which includes a frame 100, a transmission component 200 and a tension wheel 300. The frame 100 serves as a supporting base, and the transmission component 200 and the tension wheel 300 are mounted on the frame 100.
[0033] Specifically, the transmission assembly 200 and the tensioning pulley 300 are mounted on one side of the stand 100. The transmission assembly 200 includes a first pulley 210, a second pulley 220 and a transmission belt 230 arranged at intervals.
[0034] The first pulley 210 is larger than the second pulley 220. The first pulley 210 is the driving pulley, and the second pulley 220 is the driven pulley. The two ends of the transmission belt 230 are respectively connected to the first pulley 210 and the second pulley 220.
[0035] The transmission belt 230 has a tight side and a slack side between the first pulley 210 and the second pulley 220. The tensioning pulley 300 is located on the outside of the slack side of the transmission belt 230 and is used to tension the transmission belt 230.
[0036] Specifically, the stand 100 is provided with an adjustment groove 143, and the tensioning wheel 300 includes a mounting part 310 and a rolling part 320. The rolling part 320 is rotatably connected to the mounting part 310, and the mounting part 310 is movably connected to the adjustment groove 143 through the adjustment member 400 to adjust the tension of the transmission belt 230.
[0037] refer to Figures 4-6 In order to facilitate positioning when the mounting part 310 is inserted into the adjusting groove part 143, a positioning cut surface 312 is formed on the mounting part 310. The positioning cut surface 312 is parallel to the side wall of the stand 100. The positioning cut surface 312 is used to position the tension wheel 300 relative to the stand 100 along the axial position of the tension wheel 300.
[0038] In other words, when the mounting part 310 of the tensioning wheel 300 is connected to the adjusting groove part 143, the mounting part 310 is connected in place when the positioning cut surface 312 on the mounting part 310 contacts the side wall of the frame 100, making it convenient for the adjusting member 400 to be further connected to the mounting part 310.
[0039] That is, the positioning surface 312 is used to contact and connect with the frame 100 during installation to assist the installation and positioning of the tensioning wheel 300 in the adjustment groove 143, facilitate the connection between the adjustment component 400 and the tensioning wheel 300, improve the positioning accuracy of the tensioning wheel 300 during installation, and achieve the alignment and connection of the adjustment component 400 and the mating hole 311 on the tensioning wheel 300 without multiple alignments, thereby reducing the assembly difficulty and improving accuracy.
[0040] Refer again Figure 2 In some embodiments of this application, a first end face 141 and a second end face 142 perpendicular to the first end face 141 are formed on the stand 100. The adjustment groove 143 is an elongated groove formed on the first end face 141. The adjustment member 400 is connected to the second end face 142. The length direction of the adjustment groove 143 is parallel to the moving direction of the adjustment member 400.
[0041] The positioning cut surface 312 is parallel to the first end face 141. During installation, the positioning cut surface 312 contacts the first end face 141 to determine the position of the mounting part 310.
[0042] The adjusting member 400 extends from the second end face 142 into the frame 100 and is connected to the mounting part 310. The adjusting member 400 drives the tensioning wheel 300 to move along the length direction of the adjusting groove 143 to realize the tension adjustment of the transmission belt 230.
[0043] In some embodiments of this application, a mating hole 311 is formed on the mounting part 310, and a connecting hole 144 is formed on the second end face 142. The axes of the mating hole 311 and the connecting hole 144 coincide, and the adjusting member 400 passes through the connecting hole 144 and connects to the mounting hole.
[0044] During installation, the mounting part 310 on the tensioning wheel 300 is inserted into the adjusting groove 143. When the positioning surface 312 contacts the stand 100, the mating hole 311 corresponds to the position of the adjusting member 400, which facilitates the connection between the adjusting member 400 and the mating hole 311.
[0045] In some embodiments of this application, an external thread section is formed on the outer wall of the adjusting member 400, and an internal thread is formed in the mating hole 311, so that the adjusting member 400 is threadedly connected to the mating hole 311.
[0046] Rotating the adjusting member 400, the mounting part 310 moves relative to the adjusting member 400 within the adjusting groove 143 under threaded engagement.
[0047] The rotating adjusting member 400, under threaded engagement, allows the tensioning wheel 300 to move relative to the adjusting member 400 within the adjusting groove 143, thereby adjusting the tension of the transmission belt 230.
[0048] In some embodiments of this application, the mounting portion 310 has two mounting surfaces 313 symmetrically arranged on both sides of the mating hole 311, and the axis of the mating hole 311 is parallel to the mounting surfaces 313.
[0049] The mounting part 310 with the assembly facet 313 fits better with the adjusting groove part 143. The upper and lower corresponding connections of the assembly facet 313 and the adjusting groove part 143 improve the stability of the connection and the movement of the tension wheel 300.
[0050] In some embodiments, the assembly cut surface 313 and the positioning cut surface 312 are specifically formed by cutting the cylindrical mounting portion 310 on opposite sides, and the assembly cut surface 313 is perpendicular to the positioning cut surface 312 on the corresponding side.
[0051] Refer again Figure 5 In some embodiments of this application, a connecting shaft 330 is provided on the mounting part 310, the radial dimension of the connecting shaft 330 is smaller than that of the mounting part 310, and the rolling part 320 is at least one bearing member 321 provided on the connecting shaft 330.
[0052] In some embodiments, the rolling part 320 includes at least two bearing members 321, each bearing member 321 being a rolling bearing, which are sequentially connected to the connecting shaft 330.
[0053] The bearing 321 is rotatably connected to the connecting shaft 330. The two ends of the transmission belt 230 are connected to the first pulley 210 and the second pulley 220. The rolling part 320 is located on the outside of the transmission belt 230. The tension of the transmission belt 230 is adjusted by changing the position of the tensioning wheel 300.
[0054] A partially cylindrical mounting portion 310 is also formed between the positioning surface 312 and the connecting shaft 330, which limits the rolling portion 320.
[0055] In some embodiments of this application, a groove 331 is formed at the end of the connecting shaft 330 away from the mounting portion 310, and a retaining ring 340 is detachably connected to the groove 331 to limit the rolling portion 320.
[0056] After the bearing component 321 is connected to the connecting shaft 330, the retaining ring 340 is installed in the slot 331 of the connecting shaft 330. One end of the bearing component 321 is limited by the mounting part 310, and the other end is limited by the retaining ring 340.
[0057] In some embodiments of this application, the adjusting member 400 includes an adjusting end 410 and a threaded rod 420, an external threaded section is formed on the threaded rod 420, the adjusting end 410 is located outside the second end face 142, and a non-circular hole is formed on the end face of the adjusting end 410 for convenient adjustment.
[0058] In some embodiments, an internal hexagonal hole is formed on the adjustment end face, which allows the user to rotate the adjustment member 400 with an auxiliary tool to move the mounting part 310 within the adjustment groove 143.
[0059] In other embodiments, the outer wall shape of the adjusting end 410 can also be non-circular, such as hexagonal, to facilitate rotation by the user using auxiliary tools such as wrenches.
[0060] During installation, the end extends through the connecting hole 144 on the second end face 142 into the frame 100, and the end is threadedly connected to the mating hole 311 on the mounting part 310. The adjusting end 410 is located outside the second end face 142, and the non-circular hole formed on its end face allows the user to easily operate and rotate it.
[0061] Refer again Figure 2 In some embodiments of this application, the stand 100 includes a supporting crossbeam 110, a supporting longitudinal beam 120, a supporting vertical beam 130, and a diagonal bracing beam 140.
[0062] There are two support beams 110, which are placed on the ground at intervals. The support longitudinal beam 120 is connected between the two support beams 110, and the support beams 110 and the support longitudinal beam 120 form a horizontal support base.
[0063] The support beam 130 is vertically connected to the support longitudinal beam 120, and the diagonal brace 140 is connected at an angle to the support longitudinal beam 120 and the support beam 130. The support longitudinal beam 120 provides support for the diagonal brace 140. The transmission assembly 200 and the tension wheel 300 are mounted on the diagonal brace 140.
[0064] The diagonal bracing beam 140 is a hollow structure formed by welding steel, with the first end face 141 and the second end face 142 formed on the diagonal bracing beam 140.
[0065] From a process perspective, in order to facilitate the machining of the adjustment recess on the diagonal brace beam 140, this application forms a machining round hole at the end of the adjustment recess to facilitate the machining of the adjustment recess.
