Detailed implementation manners

[0036] The following Figure 1-6 further describes the present application in detail.

[0037] The embodiment of the present application discloses a limiting device.

[0038] Referring to Figure 1 and Figure 2 , the limiting device includes a mounting base 1, a bolt 2, a handle 3 and an elastic member 4. The mounting base 1 is arranged in a cylindrical shape. A through sliding groove 11 is opened in the mounting base 1 along its own length direction, and a threaded portion 151 is provided at one end of the mounting base 1 to realize threaded connection with the mounting pipe 5 of the spinning bike. The bolt 2 includes an insertion rod 21 and a rotating shaft 22. The insertion rod 21 is slidably connected in the sliding groove 11. One end of the insertion rod 21 far from the threaded portion 151 of the mounting pipe 5 protrudes from the mounting base 1 and is vertically and fixedly connected to the rotating shaft 22.

[0039] The handle 3 is arranged at one end of the mounting base 1 close to the rotating shaft 22. A connecting groove 31 is opened at one end of the handle 3 close to the mounting base 1. At the same time, two abutting ribs 12 are formed at intervals and protrude from one end of the mounting base 1 close to the handle 3. The two sides of the two abutting ribs 12 away from each other respectively abut against the two inner side walls of the connecting groove 31, and the rotating shaft 22 is rotatably connected in the handle 3. In this embodiment, the elastic member 4 is a spring, and in other embodiments, it can also be an elastic column. The elastic member 4 is located in the sliding groove 11, and one end of the elastic member 4 elastically abuts against one end wall of the mounting base 1, and the other end elastically abuts against the periphery of the insertion rod 21 to drive the insertion rod 21 to protrude from one end of the mounting base 1 far from the handle 3 and make the handle 3 abut against the mounting base 1.

[0040] Referring to Figure 1 and Figure 3, in practical applications, the threaded portion 151 of the thread of the mounting base 1 is threadedly connected to the mounting tube 5 of the spinning bike. Since the two abutting ribs 12 respectively abut against the two inner side walls of the connecting groove 31, the staff can drive the mounting base 1 to rotate by applying force to the handle 3, so that the mounting base 1 is stably fixedly connected to the mounting tube 5. Moreover, under the action of the elastic member 4, the insertion rod 21 slides along the sliding groove 11 and protrudes from one end of the mounting base 1 away from the handle 3, so that the insertion rod 21 is inserted into the mounting hole of the adjusting tube 6 of the spinning bike, so as to realize the fixation between the mounting tube 5 and the adjusting tube 6, that is, to realize the fixation of the spinning bike seat. It should be noted that the staff can make the handle 3 perpendicular to the mounting base 1 by rotating the handle 3, so as to facilitate applying force to the handle 3, thereby facilitating the rotation of the mounting base 1.

[0041] Refer to Figure 3 and Figure 4 , wherein, when the seat height needs to be adjusted, since the rotating shaft 22 is rotatably connected to the handle 3, the staff rotates the handle 3 to drive the insertion rod 21 to slide along the sliding groove 11. At this time, the elastic member 4 is compressed and the insertion rod 21 extends into one end of the mounting base 1 away from the handle 3, so that the insertion rod 21 disengages from the mounting hole, and then the adjusting tube 6 can be slid. After that, just rotate the handle 3 again, so that the insertion rod 21 is inserted into other mounting holes under the reset of the elastic member 4, without always pulling the handle 3 outwards. The operation is simple and convenient, thus facilitating the adjustment of the seat height.

[0042] Refer to Figure 4 , in some embodiments, a limiting block 13 is further protruded from one end of the mounting base 1 close to the handle 3. The limiting block 13 is located between the two abutting ribs 12 and is limited in the connecting groove 31. It should be noted that the limiting block 13 is limited in the connecting groove 31 before and after the handle 3 rotates. In this way, the contact area between the mounting base 1 and the handle 3 can be increased, so that the handle 3 can drive the mounting base 1 to rotate more stably before and after rotation, and thus the mounting base 1 can be more stably threadedly connected to the mounting tube 5.

[0043] Refer to Figure 5 , in some embodiments, a rotation guiding fillet 32 is provided at one end of the handle 3 close to the mounting base 1. When the handle 3 rotates, the rotation guiding fillet 32 abuts against the mounting base 1, and under the guidance of the rotation guiding fillet 32, it is convenient to realize the rotation of the handle 3.

[0044] In some embodiments, holding grooves 33 are formed on both sides of the handle 3. The holding grooves 33 are arc grooves, so as to facilitate the staff to hold, thereby facilitating the staff to apply force, and further facilitating the rotation of the handle 3 and the rotation of the mounting base 1 through the handle 3.

[0045] In some embodiments, a force - applying groove 34 is formed on the lower side of the handle 3. The force - applying groove 34 is for the staff to apply force, thereby further facilitating the rotation of the handle 3. At the same time, the force - applying groove 34 can reduce the materials required for manufacturing the handle 3, effectively reducing the production cost of the handle 3, and thus reducing the production cost of the limiting device.

[0046] Referring Figure 6 , in some embodiments, the mounting seat 1 includes a plastic seat body 14 and a metal threaded head 15. The abutting rib 12 and the limiting block 13 are provided on the plastic seat body 14, and the plastic seat body 14 is made of plastic material to ensure the production cost of the mounting seat 1. The metal threaded head 15 is fixedly connected to one end of the plastic seat body 14 away from the abutting rib 12 by injection molding, and the threaded portion 151 is provided on the metal threaded head 15. Since the metal threaded head 15 is made of metal material, it can ensure the strength of the threaded portion 151 and delay the aging of the threaded portion 151, so as to improve the service life of the metal threaded head 15, and thus improve the overall service life of the limiting device.

[0047] In some embodiments, the metal threaded head 15 is provided with an embedding groove 152 along its circumferential direction, and the plastic seat body 14 is embedded in the embedding groove 152, so that the injection molding between the metal threaded head 15 and the plastic seat body 14 is more sufficient, thereby improving the tightness and stability of the connection between the metal threaded head 15 and the plastic seat body 14, and ensuring the stability of the mounting seat 1 during use.

[0048] The implementation principle of this embodiment is as follows: In practical applications, the threaded portion 151 of the thread of the mounting seat 1 is threadedly connected to the mounting tube 5 of the spinning bike. Since the two abutting ribs 12 respectively abut against the two inner side walls of the connection groove 31, the staff can drive the mounting seat 1 to rotate by applying force to the handle 3, so that the mounting seat 1 is stably fixedly connected to the mounting tube 5. And, under the action of the elastic member 4, the insertion rod 21 slides along the sliding groove 11 and protrudes from one end of the mounting seat 1 away from the handle 3, so that the insertion rod 21 is inserted into the mounting hole of the adjustment tube 6 of the spinning bike, so as to realize the fixation between the mounting tube 5 and the adjustment tube 6, that is, to realize the fixation of the spinning bike seat. It should be noted that the staff can make the handle 3 perpendicular to the mounting seat 1 by rotating the handle 3, so as to facilitate applying force to the handle 3 and thus facilitate rotating the mounting seat 1.

[0049] Among them, when the seat height needs to be adjusted, since the rotating shaft 22 is rotatably connected to the handle 3, the staff rotates the handle 3 to drive the insertion rod 21 to slide along the sliding groove 11. At this time, the elastic member 4 is compressed and the insertion rod 21 extends into one end of the mounting seat 1 away from the handle 3, so that the insertion rod 21 is disengaged from the mounting hole, and then the adjustment tube 6 can be slid. After that, just rotate the handle 3 again, so that the insertion rod 21 is inserted into other mounting holes under the reset of the elastic member 4, without always pulling the handle 3 outwards. The operation is simple and convenient, thus facilitating the adjustment of the seat height.

[0050] The embodiment of the present application also discloses a spinning bike.

[0051] The spinning bike includes the limiting device described in the above embodiment.
