Description

Technical Field

[0001] The utility model relates to the field of tire changing machines, in particular to a fixing device for tire changing machines. Background Art

[0002] In order to reduce the tire blowout rate, many measures have been taken by related industries, such as applying glue to the inner surface of the tire, so that when it is hit by sharp stones or nails on the road, the probability of puncture can be reduced, thus achieving the purpose of anti-puncture and anti-explosion. However, before applying glue to the inner surface of the tire, the tire must be removed from the wheel. Since the bead part of the tire is very tightly combined with the rim, it is difficult to remove the tire manually. At the same time, if the tire is removed by hand, not only is the work efficiency low, but it is also laborious and easy to hurt fingers. Tire changers, also called tire changers and tire removers, are used to install and unload automobile tires. They can replace tires for different vehicles such as cars, motorcycles and heavy trucks. They are essential equipment for automobile repair shops and 4S shops.

[0003] A Chinese patent discloses a fixing device for a tire changer for electric vehicle production, and its patent announcement number is CN209869987U. In the fixing device for a tire changer for electric vehicle production in the patent, the base is provided with a plurality of connecting members fixedly arranged at the upper end inside the base, the lower ends of the plurality of connecting members are fixedly connected to shock-absorbing springs, the side ends of the base are fixedly connected to the fixing device, both sides of the base are fixedly provided with fixing grooves, the base is fixedly connected to the chassis through the fixing grooves, a lifting hydraulic cylinder is fixedly installed on one side of the chassis, a motor is fixedly installed on one side of the lifting hydraulic cylinder, a tire pressing bowl is fixedly arranged on one side of the motor, a support rod is fixedly arranged on the middle end of the chassis, and a frame is fixedly arranged on the other side of the chassis. By fixing the fixing device at the lower end of the tire changer, the bottom end of the tire changer cannot directly contact the ground, the vibration of the tire changer during operation is reduced, and the fixing performance is good. At the same time, a limit plate is fixedly installed at the upper end of the clamp to prevent the tire changer from generating a large arc due to force imbalance during operation, thereby increasing the safety performance of the tire changer, making it more practical and having a higher value for promotion and use.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, when a fixing device is used to assist a tire changing machine in operating, the height of the fixing device remains unchanged due to the different heights of different workers. As a result, workers often need to bend over, twist their bodies, or find other ways to adapt to the fixed height when performing operations such as tire repair or replacement, making the entire operation process quite laborious.

[0006] (2) In the prior art, tires have different sizes, and the existing fixing devices are often not flexible enough in design and cannot perfectly adapt to tires of all specifications. This may result in loose fixation during the tire fixing process, thereby affecting the tire maintenance quality and work efficiency.

[0007] (3) In order to quickly and effectively fix the tire, many fixing devices in the prior art use an electrically controlled clamping method. However, this clamping method may exert excessive clamping force on the tire surface due to improper control or mechanical failure, which may not only cause damage to the tire surface but also increase the cost of subsequent repairs and replacements.
