Clamping plate type anti-shearing lock of electric vehicle

Abstract

The invention relates to a hardware lock, in particular to a clamping plate type electric vehicle anti-shearing lock capable of resisting any civil scissors. The anti-shearing lock mainly comprises a lock bar rack, a lock bracket rack and a cylinder, and is characterized in that one or more lock bars are arranged on the lock bar rack, and one or more grooves are formed in the head of each lock bar or a retractable bolt I driven by the cylinder is arranged radially at the head of the lock bar; one or more lock bar holes are formed in the lock bracket rack, and a retractable bolt driven by the cylinder is arranged on the side surface of each lock bar hole; or one or more lock bar holes are formed in the lock bracket rack, and a bolt shoulder allowing the bolt on each lock bar to be clamped in is arranged in a port of each lock bar hole. During work, the lock bar rack penetrates through a gap of a tire hub, the lock bracket rack is inserted into lock bars, then a key is rotated so that the bolts are clamped into the grooves in the lock bars, and the tire is locked, the lock bars surround the lock bar rack and the lock bracket rack, at the moment, a thief cannot shear the lock by hydraulic shears.

Description

Technical field: [0001] The invention relates to a hardware lock, in particular to a splint type electric vehicle anti-shear lock which can resist any civilian scissors. Background technique: [0002] The motorcycle locks currently on the market are basically in the form of exposed rods, that is, the U-shaped lock rod is a round rod or a square rod and the U-shaped part is exposed, and the size of this part of the rod is also the thinnest, but The diameters or grades of materials used in various models are different. In addition, these lock bars are made hard and resistant to shearing through heat treatment of these materials; but these materials have a weakness. If the heat treatment is too hard, the lock bars will become brittle. A thief hits the lock bar with a hammer and it will break. On the contrary, if the heat treatment is too soft, the current hydraulic shears have enough shear force to cut it off. Therefore, the heat treatment of the lock bar of the motorcycle anti...

[0002] The motorcycle locks currently on the market are basically in the form of exposed rods, that is, the U-shaped lock rod is a round rod or a square rod and the U-shaped part is exposed, and the size of this part of the rod is also the thinnest, but The diameters or grades of materials used in various models are different. In addition, these lock bars are made hard and resistant to shearing through heat treatment of these materials; but these materials have a weakness. If the heat treatment is too hard, the lock bars will become brittle. A thief hits the lock bar with a hammer and it will break. On the contrary, if the heat treatment is too soft, the current hydraulic shears have enough shear force to cut it off. Therefore, the heat treatment of the lock bar of the motorcycle anti-theft lock outside has a certain range. , which also appeared on the packaging box of some locks marked anti-20 tons, anti-30 tons, or even anti-50 tons of hydraulic shear content, from the above content introduction, as long as the shear force of the hydraulic shear exceeds its specified The maximum shearing force that can withstand, the lock bar will be cut off, so the anti-hydraulic shearing propaganda printed on the lock box outside is actually just a beautiful lie, and the car locks in the society outside are hydraulic shearing Countless cut

We know that hydraulic shears have a certain cutting size limit (the maximum is about 25 mm), as long as the material size exceeds the maximum shearing size of hydraulic shears, hydraulic pliers cannot cut it, but due to the cost, the lock bar does not It is possible to make it so big. First, the hole on the wheel is not that big, and the lock rod is too thick to be inserted; second, the cost is too high; third, the processing is difficult and requires a large-tonnage machine tool; It is unbearable for low-level locks, so the anti-theft function of these anti-theft locks on the market is limited, and many people's vehicles have been stolen to prove this
