And selecting the corresponding car hub nut safety lock according to different sizes of the car nuts.
The corresponding car hub nut safety lock is selected according to different numbers of car nuts.
The safety lock for the car hub nut is provided with 4 lock sleeves and 5 lock sleeves according to the number of the nuts.
The safety lock for the car hub nut is of types of 17-24 according to the size of the nut.
The car hub nut safety lock utilizes an internal dustproof rubber sleeve to prevent dust from entering the inside of the lock cylinder to influence the unlocking sensitivity.
The technical effects achieved by the present invention are as follows.
The wheel hub nut locking device is light, small, durable, convenient to install, low in cost, simple in structure, simple in technology and easy to achieve, and the wheel hub nut is guaranteed to be never loosened.
The invention is described in detail below with reference to the figures and examples.
The device is mainly installed on 4 or 5 improved nuts of a car hub.

Fig. 4 is a side view of a modified nut of the present invention.
In the figure: 01. the novel hub nut assembly comprises a nut safety lock assembly 02, a mechanical lock cylinder assembly 03, a mechanical chuck assembly 04, a nut sleeve assembly 05, an improved hub nut 06, a mechanical chuck 07, a dustproof soft rubber pad 08, a hub center small label cover 09, a safety lock nut sleeve 10, a nut dustproof soft rubber ring 11, a safety lock, hub clamping teeth 12, a hub nut internal thread hole 13, a nut 14 with a gear-shaped clamping groove, a hub nut head and nut connecting wall 15 and a hub nut head.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
The safety lock of the car hub nut needs to buy the safety lock of the car hub nut with the model corresponding to the car when being used for the first time.
The classification and the working principle of the safety lock of the car hub nut.
The safety lock of the car hub nut is mainly used in 2 types, and the working principle is the same
The first type: the safety lock with 4 nut sleeves is mainly installed on 4 car hubs with fastening screws.
The second type: the safety lock with 5 nut sleeves is mainly installed on 5 car hubs with fastening screws.
The working principle of the safety lock of the car hub nut.
The analysis is as follows with fig. 1 as an example.
Firstly, a safety lock of a car hub nut with a model corresponding to a car is purchased.
And (3) selecting a modified nut (shown in figure 4) of a type corresponding to the hub nut of the car to replace.
The improved nuts are adjusted to enable the clamping grooves (13) of the 4 nuts to be mutually opposite.
And removing a small cover mark (08) at the center of the hub.
The key inserted into the car is manually rotated forward or backward by 90 degrees.
The anti-theft mechanical chuck (06) in the safety lock assembly is contracted into the safety lock arm.
The aligning nut is easily shaken to the car hub safety lock assembly (03), and each nut sleeve (04) and each safety lock cylinder (02) are pressed by strength to be sleeved on the nut.
The key of the car is released, so that a mechanical chuck (06) inside the safety lock of the car hub nut is meshed with the improved nut gear groove (13) in the figure 4.
The lock body latch (11) of the car hub nut safety lock is locked with the hub positioning hole, so that the car hub nut safety lock cannot be loosened.
The safety lock of the car hub nut is locked with the hub nut and can not be loosened, so that 4 nuts for fastening the hub become a whole and can not be loosened singly.
And pulling out the key ring of the car to be provided with the original car hub center small cover mark (08).
When the car is unlocked without a key, a thief cannot steal the car hub by using a wrench, and the car hub has the function of safety and theft prevention.
Meanwhile, accidents caused by the fact that the whole hub falls off due to the loosening of individual nuts when the wheel runs at a high speed can be avoided, and the life safety of vehicles and personnel is further improved.
