New description: [New technology field] This creation department is related to exercise bikes. More specifically, it refers to the brake adjustment mechanism and magnetoresistive device of an exercise bike. [Prior Art] Press 'General exercise bikes mainly use the rotation of a resistance wheel to achieve the effect of the fitness. However, 'the resistance wheel of the above exercise bike must generate resistance by a resistance unit' and the current resistance unit currently has two metamorphosis, namely, the contact type resistance unit and the other is the reluctance type resistance unit, in which the contact The type of resistance unit 'mainly uses the force of contact with the resistance wheel to change the resistance of the adjustment resistance wheel. Of course, the contact is used to achieve the effect of the brake. However, since the contact type resistance unit is prone to wear, it is necessary to replace the new product from time to time. The extra expense is so much less popular than the average person. The magnetoresistive resistance unit utilizes a magnetic force to generate a suction force with the resistance wheel to provide a resistance for the user to step on. The general reluctance type resistance unit is mainly composed of an adjustment mechanism and a magnetoresistive device. The resisting device is configured to generate a magnetic force to cause resistance to the rotation of the resisting wheel, and the adjusting mechanism is coupled to the magnetic=set to adjust the position of the magnetoresistive device to change the resistance. However, the above-mentioned adjusting mechanism mainly utilizes the rotation. To push the upper and lower displacement of a screw, but because the upper and lower displacement stroke of the bolt depends on the one-way thread of the M374886 on the screw, only one rotation of the bolt can be pushed for a predetermined stroke movement. There are still problems that are not fast enough. In addition, since the above-mentioned magnetoresistive device is mainly composed of a magnet provided on two metal sheets, the two metal sheets are connected to keep the two metal sheets at the side of the resistance wheel, but the two metal sheets are easy. The situation of skewing occurs, and the magnetic resistance to the resistance wheel is not uniform enough, and the action is unstable.

In the upper threaded hole 21 of the sleeve 2 2 〇 M374886, the inner sleeve 20 is located in the two-way screw 3 - 2 In the upper half, the limiting member 4 is further deducted to the middle of the screw 32 of the control member 3, and the two-way screw 2 of the control member 3 is juxtaposed with the inner sleeve 2 The person is in the limit hole 1 of the outer sleeve 1 and is biased by the limiting member 4 to the other end of the spring 5 Q, and the lock 80 is the outer sleeve! The keyhole locker 4 is inserted into the long groove 2 2 of the inner sleeve member 20, and the post 6 is inserted into the sliding hole 12 of the outer spring sleeve ίο, and the reverse direction The threaded hole 61 is screwed to the reverse threaded portion 322 of the control mechanism 30, and the screw 6 2 of the cup 60 is connected to the first joint portion 7 of the joint unit 7〇, and the joint unit 7 is connected. The second connecting portion 72 of the crucible penetrates into the slot 9 1 5 of the base 9 9 of the magnetoresistive device 90 and is pivoted by the through hole 9 7 to be pivoted to The adjustment mechanism i 枢 is pivotally connected to the magnetoresistive device 20 0 . Of course, the adjusting mechanism of the outer sleeve of the adjusting device is fixed on the bracket 9 of the exercise bicycle, and the seat 9 1 of the magnetoresistive device 2 is also pierced by the connecting portion 9 at the same time. The worker 3 is pivotally connected to the bracket 98. When it is desired to adjust the resistance generated by the device 2 QQ to one of the exercise wheels of the exercise vehicle, the control member ^ 〇 ' of the adjustment mechanism can be rotated, when the control member 3 is rotated in the forward direction, Since the inner sleeve 2 is not rotated by the action of the lock member 80, the forward thread 2 1 of the control member 3 and the forward threaded hole 3 of the inner sleeve 2 are produced. Acting to shift the control member 3 Q downwards - the predetermined first interval is 9 M374886, so that the post 60 is also synchronously moved down with the control member 30, and this control is simultaneously The reverse threaded section 3 2 2 of the member 30 also acts on the reverse threaded hole 6 1 of the post 60, and the post 60 is displaced downwardly by a second distance relative to the control member 30. The magnetic reluctance generated by the resistance wheel 79 is changed by interlocking the reluctance device 200; the course of the control thread 30 is 3 2 1 when the control member 30 is rotated in the reverse direction. And the inner threaded hole 3 2 1 of the inner sleeve 20 acts, and the control member 30 is displaced upward by a second distance, so that the rod 60 is also the same at this time. Stepwise, as the control member 30 moves up, and at the same time, the reverse thread segment 3 2 2 of the control member 30 also acts on the reverse threaded hole 6 1 of the post 60, and the post 6 is actuated. 0 is shifted upward by a second distance relative to the control member 30. In this way, regardless of whether the control member 30 rotates in the forward or reverse direction, the rod 60 and the magnetoresistive device 200 can be displaced by double stroke to achieve the purpose of rapid adjustment. When the emergency braking is to be performed, the control member 30 is directly pressed to directly drive the post 60 and the magnetoresistive device 200 to be displaced for emergency braking, and is limited by the locking member 80. The axial displacement stroke of the inner sleeve 20 is. Further, since the base body 9 1 of the magnetoresistive device 200 is a system, the parallel pitch of the two wing portions 9 1 2 can be maintained constant to maintain a uniform magnetic attraction resistance to the resistance wheel 97. Moreover, since the interlocking effect of mutual magnetic attraction is generated between the shutter 93 and the magnets 9, the efficiency of the magnetic resistance is further improved.
