Description

Stand device for bicycle

The invention refers to a bicycle frame stand device, wherein the bicycle frame stand device is a technical field for providing a bicycle stand stand.

The first press means that a parking rack 10 is provided with a base 11 on the bottom side, a front positioning frame 12 and a rear positioning frame 13 in combination. The base 11 is fixed with an upward lug seat 112, and an arc-shaped hole 113 is provided on the lug seat 112. The arc-shaped hole 113 has a blocking groove 1131, a larger-diameter sliding hole 1132 and a smaller-diameter sliding hole 1133 The front positioning frame 12 is pivotally connected and combined with a pulling shaft 14, and then, a lateral fixing rod 114 is disposed between the two lug seats 112 and a circling spring 115 is sleeved, and one end of the circling spring 115 is fixed to the fixing rod 114. The other end is provided with a buckle foot 1151 to be locked on the front positioning frame 12, and a contact wheel 122 is pivotally arranged on the top of the front positioning frame 12. The rear positioning frame 13 is pivotally disposed above the base 11 and has a rotating frame 134 above the rear positioning frame 13. The rotating frame 134 is recessed forward and backward with a wheel swing groove 1341 corresponding to the contact wheel 122 (as shown in FIG. 1 ).

However, the parking rack 10 spans the wheel 20 at the rear of the bicycle 2 with the wheel swing groove 1341 and the abutment wheel 122. The wheel 20 generally has a metal rim 201, and the metal rim 201 supports an inflated and forced tension , Elastic and absorbent rubber rim 202, the mandatory tension, elasticity and adsorption of the rubber rim 202 are beneficial for the wheel 20 to be stably spanned between the wheel swing groove 1341 and the abutment wheel 122, and then act as a rubber wheel After the ring 202 is degassed, its compulsory tension, elasticity and adsorption are not available, and its wheel 20 must be separated from the wheel swing groove 1341 and the span of the abutment wheel 122, and the bicycle 2 is toppled (e.g., the second and third Figure shown; In addition, the rubber rim 202 outgassing in Figure 4 Shown).

Then, the front positioning frame 12 is pulled off the lug seat 112 by the pulling shaft 14, so that the pulling shaft 14 and the front positioning frame 12 follow the larger diameter sliding hole 1132 and the smaller diameter sliding hole 1133 to rotate and then snap into the blocking groove 1131, or snap into a larger diameter sliding hole 1132 after rotation. However, the pulling shaft 14 must have a relatively large force to operate the pulling, so that when the front positioning frame 12 needs to be rotated, the operation is not easy and laborious (such as: Figure 1; In addition, the first to 4 For details of the picture, please refer to the M401598 case).

In addition, it refers to another second parking frame 1A. The second parking frame 1A has a positioning frame 13A, and the positioning frame 13A has a second wheel swing groove 134A corresponding to the second contact wheel 12A recessed in the front and rear. The second contact wheel 12A and the second wheel swing groove 134A also have the same. When the rubber rim 202 is out of air, its wheel 20 must be separated from the wheel swing groove 134A, the contact wheel 12A spans, and the bicycle 2 falls over. (As shown in Figure 5; in addition, the wheel 20 and the rubber rim 202 are not shown in Figure 5, so the wheel 20 and the rubber rim 202 please refer to Figure 4; in addition, the details of Figure 5 please (Refer to US006062396A case).

Therefore, there is a problem that the parking rack 10 cannot be positioned across after the wheels 20 are degassed, so it is necessary to eliminate and eliminate this lack.

In view of the above, it is known that the conventional parking rack has a lack of spanning positioning after the wheels are degassed. Therefore, the inventor of the present case is urged to develop in the direction of solving the problem that the wheel can be spanned after degassing. And then think about it, the use of packet connection is the best.

The stand device of the bicycle frame of the present invention is provided with a flat portion, the flat portion There is a frame wheel groove with a front-rear direction and a long distance, and the frame wheel groove is distributed with a pivoting portion that is relatively inclined downward, and the pivot wheel portion is provided in parallel on the left and right of the frame wheel groove. A wheel clamp is pivotally connected, the wheel clamp is provided with a wheel clamp joint portion matching the pivot joint portion, and the pivot joint portion and the wheel clamp joint portion are penetrated by a positioning shaft, the positioning shaft is penetrated by an elastic element, and the rotation The elastic element is provided with two reset terminals. One of the reset terminals extends downward and abuts against the pivoting portion, and the other reset terminal just rotates and abuts against the lower side of the wheel clamp. Then, the wheel clamp is provided with a wheel receiving arc surface parallel to the pivoting portion, and the wheel receiving arc surface is formed with a wheel receiving portion on the left and right sides of the wheel groove.

The flat part of the present invention is provided with a round groove frame tube, and the front end of the round groove frame tube is further provided with a bending part, and each of the left and right sides of the bending part extends backwards with a parallel connecting end part, and the connecting end part There is a leg tube horizontally below, so that the connecting end and the leg tube are enclosed to form the wheel groove, and the connecting end is fixed with four pivot joints in the range of the wheel groove , The pivoting seat is provided with the pivoting portion.
