With reference to shown in Fig. 1, the folding fixing device 10 of the present utility model is applied to a treadmill, wherein, the treadmill mainly comprises a base 21, an armrest frame 22, a height adjustment device 23 and a treadmill 24, on the base 21 A height adjustment device 23 is provided, the armrest frame 22 is then uprightly arranged on the front end of the base 21, and the front end of the running platform 24 is pivotally arranged on the height adjustment device 23, so that the height adjustment device 23 can adjust the oblique height of the running platform 24.

2 and 3, the folding fixture 10 is used to fix the running platform 24 in a folded position, and it includes an inner tube 11, an outer tube 12 and a clamping device 30, and one end of the inner tube 11 is It is pivotally arranged at the bottom of the rear end of the treadmill 24, and the other end is telescopically arranged in the outer tube 12. The inner tube 11 is provided with one or a plurality of adjustment holes 111 arranged in a straight line and equally spaced.

With reference to Fig. 1, Fig. 3 and Fig. 4, one end of the outer tube 12 is provided with an opening to be connected to the inner tube 11, and the other end is pivotally mounted on the base 21, and the outer tube 12 is provided with a corresponding adjustment hole 111. perforation 121 . The clamping device 30 is fixed on the outer tube 12 at the position corresponding to the perforation 121, and includes a fixed seat 31, a movable piece 32, a pawl 33, a pivot pin 34, a return spring 35, and a torsion spring 36 With a fastener 37; the fixed seat 31 is fixed on the position of the corresponding perforation 121 on the outer tube 12 and has a fixed sheet 314, a vertically protruding seat 311 located at the bottom of the fixed sheet 314 side, and a seat with the seat 311 is on the same side as the U-shaped positioning hook 312 on the top of the fixing piece 314. The fixing piece 314 has a long hole 310 facing the perforation 121. The side of the fixing piece 314 different from the seat 311 is provided with a first spring pivot pin 313 .

The movable piece 32 is slidably arranged on the fixed seat 31 and includes a guide piece 321 and a slide piece 322 perpendicular to the guide piece 321. The guide piece 321 is slidably arranged between the positioning hook 312 and the seat 311, and There is a pin hole 326 corresponding to the elongated hole 310, a second spring pivot pin 323 protruding from its side and corresponding to the first spring pivot pin 313, and a curling handle 324 and sliding piece 322 located at one end away from the fixed seat 31 Then it can slide on the seat 311 .

The pawl 33 is pivotally arranged on the movable seat 32, one end of which has a pivot hole 331, and the other end is provided with a transverse engaging groove 332 and an inclined guide surface 333; the pivot pin 34 is slidably arranged in the long hole 310, and One end passes through the elongated hole 310, the pin hole 326, the torsion spring 36 and the pivot hole 331 in sequence and protrudes out of the pivot hole 331. The fastener 37, such as a C-shaped buckle, is set and locked on the pivot pin 34 protruding from the pivot hole. The end of 331 is used to position the pawl 33 , and the torsion spring 36 is looped on the pivot pin 34 between the pawl 33 and the guide piece 321 to provide elastic force for the pawl 33 to pivot in the direction of the guide piece 321 .

Two ends of the return spring 35 are respectively fixed on the second spring pivot pin 323 of the first spring pivot pin 313 to provide elastic force for the movable piece 32 to return to an initial position.

2 and 4, when the treadmill 24 is pushed from the horizontal state to the folded position in the vertical state, the inner tube 11 will be drawn away from the outer tube 12, and at this time, the movable piece 32 will face the outer tube 12 Push it in so that one end of the pawl 33 passes through the through hole 121 and is partially accommodated in one of the adjustment holes 111. At the same time, the movable piece 32 elongates the return spring 35. When the inner tube 11 is pulled away from the outer tube 12, the adjustment The hole 111 contacts the inclined guide surface 333 of the pawl 33, and the pawl 33 pivots clockwise through the inclined guide surface 333 to make the pawl 33 disengage from the adjustment hole 111. When the pawl 33 disengages from the adjustment hole 111, the torsion spring 36 The elastic force will pivot the pawl 33 in the counterclockwise direction and slide on the inner tube 11, so that the pawl 33 will slide down the next adjustment hole 111 again and make a collision sound, and so on until the treadmill 24 is pushed to the vertical state. In the folded position, since the pawl 33 can be kept in one of the adjustment holes 111 at any time, it is very convenient to use.

At this time, when the treadmill 24 is released, its own weight will press down on the inner tube 11, and the adjustment hole 111 on the inner tube 11 will also move down accordingly, so that its top edge is locked in the horizontal slot 332 of the pawl 33. At the same time, push the pawl 33 to pivot counterclockwise until the pawl 33 abuts against the sliding piece 322 and is positioned. At this time, because the inner pipe 11 has been inserted into the transverse groove 332, the inner pipe 11 and the outer pipe 12 can be firmly positioned. positioning without relative motion.

Referring to Figures 5 and 6, when the treadmill 24 is to be placed in a horizontal state from the folded position, the treadmill 24 is pushed up slightly to drive the inner tube 11 so that the top edge of the adjustment hole 111 is detached from the horizontal clamping groove 332. , the return spring 35 pulls back the movable piece 32 to make the pawl 33 break away from the adjustment hole 111, so that the inner tube 11 can be retracted in the outer tube 12, so that the running platform 24 can be placed in a horizontal state by the folded position for running.

Referring to Fig. 2 and Fig. 7, another preferred embodiment of the clamping device 30 of the present invention includes a fixing seat 41, a catch 33, a torsion spring 36, a pressing handle 42 and a pivot pin 43, Wherein, the fixing base 41 is L-shaped and is fixed on the position corresponding to the perforation 121 on the outer tube 12 and has a fixing piece 414 and a vertically protruding seat 411 located on one side of the fixing piece 414. The pawl 33 is The pivot pin 43 is pivotally arranged on the fixed plate 414, and the pivot pin 43 is provided with a torsion spring 36 for the return of the pawl 33. The pressing handle 42 is connected to the pivot pin 43 for pivoting the pawl 33. Therefore, when the treadmill 24 pushes up slightly to drive the inner tube 11 to make the top edge of the adjustment hole 111 disengage from the horizontal slot 332, the handle 42 can be pressed down to pivot the pawl 33, so that the horizontal slot 332 on it is disengaged from the adjustment hole 111. , so that the inner tube 11 can be retracted into the outer tube 12, so that the running platform 24 can be placed in a horizontal state by the folded position for running.

Referring to Fig. 2 and Fig. 8, the third preferred embodiment of the clamping device 30 of the present invention includes a fixed seat 41, a pawl 33, a torsion spring 36, a pull cord 50 and a pivot pin 43 , wherein, the fixed seat 41, the pawl 33, the torsion spring 36 and the pivot pin 43 will not be repeated. The drawstring 50 is combined with the end of the pawl 33 which is different from the horizontal slot 332, and runs through the seat 411. Therefore, when the treadmill 24 pushes up slightly to drive the inner tube 11 to make the top edge of the adjustment hole 111 break away from the horizontal slot 332, The pull cord 50 can be pulled down to pivot the pawl 33, so that the horizontal slot 332 on it is disengaged from the adjustment hole 111, so that the inner tube 11 can be retracted into the outer tube 12, so that the running platform 24 can be placed in a horizontal state from the folded position for running use.
