[0029] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0030] like Figures 1 to 4 As shown, the utility model discloses a brake line installation structure of an exercise bike, which includes a brake line 1; the brake line 1 includes a brake line sleeve 11 and a brake core line 12 inserted in the brake line sleeve 11, the first end and the second end of the brake core line 12 are respectively connected to a brake handle 2 and a brake member 3, the brake handle 2 is movably installed on an adjustment tube 4 or an armrest assembly 5 of the exercise bike A, the brake member 3 is movably installed on an exercise bike body 6 of the exercise bike A and is used to apply braking resistance to a resistance wheel 7 of the exercise bike A, the first end and the second end of the brake line sleeve 11 are respectively connected to the adjustment tube 4 and the exercise bike body 6 of the exercise bike A, the adjustment tube 4 and the front frame tube 61 of the exercise bike body 6 are mutually nested and the installation height of the adjustment tube 4 is adjustable, and the armrest assembly 5 is connected to the top of the adjustment tube 4; wherein, the setting of the resistance wheel 7, the installation structure of the brake member 3 and the matching structure of the brake member 3 and the resistance wheel 7 are prior arts and are not described in detail herein.

[0031] The key point of the utility model is that the brake line installation structure of the fitness bike of the utility model also includes a tensioning rope 8; the tensioning rope 8 is elastic, the first end of the tensioning rope 8 is connected to the brake line sleeve 11, and the second end of the tensioning rope 8 is connected to the fitness bike body 6. In this way, when the user adjusts the height of the brake handle 2 by adjusting the installation height of the adjustment tube 4, the brake line 1 will be pushed and pulled by the adjustment tube 4, which will easily cause the brake line 1 to be entangled or stuck. Since the first end and the second end of the tensioning rope 8 are respectively connected to the brake line sleeve 11 and the fitness bike body 6 and the tensioning rope 8 is elastic, the tensioning rope 8 will pull the brake line 1 to keep the brake line 1 in a tensioned state, thereby effectively avoiding the problem of the brake line 1 being entangled or stuck when the brake line 1 is pushed and pulled by the adjustment tube 4.

[0032] In the embodiment of the present invention, the brake line 1 can pass through the adjustment tube 4 and the front frame tube 61 of the fitness bike A, which can protect the brake line 1 and prevent the user from accidentally pulling the brake line 1. The adjusting tube 4 is provided with an adjusting fixing plate 41, and the fitness bike body 6 is provided with a main body solid plate. The first end and the second end of the brake line sleeve 11 are respectively connected to the adjusting fixing plate 41 and the main body fixing plate 63 to fix the brake line sleeve 11; specifically, the first end and the second end of the brake line sleeve 11 can be respectively provided with a first joint 13 and a second joint 14, the first joint 13 is provided with a first annular groove 131, and the second joint 14 is provided with a second annular groove 141; the adjusting fixing plate 41 is provided with an opening for inserting into the first annular groove 131 so that the adjusting fixing plate 41 and the first annular groove 131 are plugged and matched, and the main body fixing plate 63 is provided with an opening for inserting into the second annular groove 141 so that the main body fixing plate 63 and the second annular groove 141 are plugged and matched; such a configuration enables the first end and the second end of the brake line sleeve 11 to be conveniently connected to the adjusting fixing plate 41 and the main body fixing plate 63, respectively.

[0033] In the embodiment of the utility model, the first end of the tension rope 8 can be connected to the middle section of the brake cable sleeve 11, so that the tension rope 8 can better pull the brake cable 1. The second end of the tension rope 8 can be connected to the rear frame tube 62 of the fitness vehicle body 6.

[0034] In an embodiment of the utility model, the lower end of the adjusting tube 4 is inserted into the front frame tube 61, and the front frame tube 61 is equipped with a locking piece 64 for locking the adjusting tube 4; specifically, the locking piece 64 is screwed with the front frame tube 61, and the locking piece 64 is equipped with a tightening block 641 for abutting against the adjusting tube 4; when the installation height of the adjusting tube 4 is to be adjusted, the locking piece 64 is first rotated in the reverse direction so that the tightening block 641 releases the abutment against the adjusting tube 4 so that the adjusting tube 4 can be moved, and then the adjusting tube 4 is moved to the desired position, and finally the locking piece 64 is rotated in the forward direction so that the tightening block 641 is tightly abutted against the adjusting tube 4 to lock the adjusting tube 4.
