Description

A kind of lock of the high efficient theftproof for motorcycle, electric motor car, bicycle

Technical field

The utility model relates to a kind of lockset, is specifically related to a kind of high efficient theftproof for motorcycle, electric motor car, bicycle lock.

Background technology

Now the lock of motorcycle in the art, electric motor car, bicycle generally has two kinds, one is electronic alarm lock, when car is in anti-theft state, car load all can send chimes of doom when being given a shock or moving, and only have after removing anti-theft feature by remote controller and could normally enable, but noise jamming is large, use simple tool can implement theft equally easily, and complex structure, cost is high, expensive; Another kind is mechanical lock, mainly include steel wire chain lock and U-shape lock, it is be inserted through between the wheel hub of back wheels of vehicle by metal bracelet or U-shape lock bar, pinning motorcycle is reached by limiting the rotation of trailing wheel, but keyhole is exposed to easily to be prized outward, and locking bar diameter is mostly easily cut off by hydraulic shear below three centimeters, security performance is low.

China's application number is the utility model of 201320856849X, a kind of lock for motorcycle is disclosed, comprise lock body and lock bridge, lock core is provided with in lock body, battery, switch and alarm circuit is provided with in described lock body, miniature bulb and relay is provided with in described lock bridge, described battery, switch, relay, miniature bulb are connected in series formation loop successively, it is in parallel with alarm circuit again after described battery is connected in series with switch, described alarm circuit comprises the normally closed auxiliary contact of electric bell and relay, the normally closed auxiliary contact serial connection of electric bell and relay.This utility model is provided with alarm circuit, after lock is cut off by hydraulic shear, chimes of doom can be sent, but still have the following disadvantages: one, the bulk strength of U-shaped structure lock body is low, very easily destroys by the structure of lock core during external impacts, security performance is low, lock body arranges the electronic installation such as relay, battery, and accumulator electric-quantity and application life all limited, use inconvenience and cost is high; Its two, on the wheel hub of U-shape lock place motor vehicle wheel, position is given prominence to, thus is easily cut off by hydraulic shear, and security performance is lower.

Utility model content

For the deficiency that prior art exists, the utility model provides the high efficient theftproof for motorcycle, electric motor car, bicycle that a kind of structure is simple, cost is low, pollution-free, security performance is high lock.

In order to achieve the above object, the technical scheme taked of the utility model:

A kind of lock of the high efficient theftproof for motorcycle, electric motor car, bicycle, comprise lock body, lock core, lock, described lock body is orbicule or oval orbicule, and lock body comprises the first lock body and the second lock body, described lock core is located at the inside of the first lock body, and described lock corresponds to the end that the second lock body is located in the position of lock core.

As optimal technical scheme, in order to ensure that lock body has good structural mechanical property, ensure that theftproof lock is conveniently locked on the spoke of wheel, effectively improves security performance simultaneously, described lock body is arranged to oval orbicule, and the major axis of lock body be 150 ~ 200mm, minor axis is 80 ~ 120mm.

As optimal technical scheme, in order to control lock weight, be beneficial to easy to carry, described lock body is made up of lightweight high hardness material.

As optimal technical scheme, have good structural mechanical property, effectively improve security performance in order to ensure lock body, effectively control manufacturing cost, the length of described lock is 20 ~ 40mm, width is 6 ~ 12mm simultaneously.

As optimal technical scheme, in order to ensure that theftproof lock is applicable to the different wheel of spoke dense degree, be beneficial to the scope of application expanding theftproof lock, the quantity of described lock can arrange single or two.

Compared with prior art, the beneficial effect that has of the utility model:

1, the lock body of orbicule or oval orbicule is set, there is good structural mechanical property, effectively improve security performance, and structure is simple, cost is low, be easy to manufacture, without the need to charging, forever using.

2, the lock body of oval orbicule is set, and the size of lock body is arranged rationally, further increases the structural mechanical property of lock body, theftproof lock is locked on the spoke of wheel, change the car locking position of traditional lock, effectively avoid explosion-proof power to tear the generation of lock phenomenon open, security performance is high.

3, lock body adopts lightweight high hardness material to make, and has both ensured that the hardness of theftproof lock is high, also ensures that theftproof lock is light, is convenient for carrying simultaneously.

4, the vibrational power flow of lock is reasonable, has both guaranteed that lock body had good structural mechanical property, and has effectively improved security performance, effectively controls manufacturing cost simultaneously.

5, single lock or two locks are set, ensure that theftproof lock is applicable to the different wheel of spoke dense degree, applied widely.

Detailed description of the invention

A kind of specific embodiment of the utility model is proposed as shown in Figure 1, a kind of for motorcycle, electric motor car, the high efficient theftproof lock of bicycle, comprise lock body 1, lock core 2, lock 3, described lock body 1 is spherical or oval ball shape body, and lock body 1 comprises the first lock body 1-1 (as shown in Figure 2) and the second lock body 1-2, it is be made up of lightweight high hardness material that the present embodiment preferably arranges lock body 1, consider that oval orbicule is convenient on the spoke of place wheel, the shape of lock body 1 is preferably arranged to oval orbicule, and the major axis of lock body 1 is 150 ~ 200mm, minor axis is 80 ~ 120mm, easy to carry, structural mechanical property is good, security performance is high.

Described lock 3 corresponds to the end that the second lock body 1-2 is located in lock core 2 position, and the length that the present embodiment preferably arranges lock 3 is 20 ~ 40mm, width is 6 ~ 12mm, guarantees security performance, effectively controls manufacturing cost simultaneously.

The quantity of described lock 3 is arranged according to the spoke dense degree of wheel, if the spoke of wheel is comparatively intensive, the end of the second lock body 1-2 preferably arranges single lock 3, as shown in Figure 5, ensures that security performance also reduces cost while high; If the spoke interval of wheel is wider, in order to ensure higher security performance, the end of the second lock body 1-2 preferably arranges two locks 3, as shown in Figure 4.

Described lock core 2 is located at the inner 1-1 of the first lock body, and as shown in Figure 3, lock core 2 comprises the dead bolt 2-1 being located at the inner 1-1 front end of the first lock, the snap close 2-2 connecting dead bolt 2-1, and different according to the quantity of lock 3, the structure of lock core 2 is done and correspondingly adjusted.

When the utility model uses: the spoke dense degree according to wheel selects monolock post lock or dual-lock column lock, first by the spoke of the first lock body 1-1 through wheel, then the lock 3 of the second lock body 1-2 end is injected lock core 2, turning key makes lock core 2 coordinate fastening with lock 3, both can lock lock.Because theftproof lock is locked on the spoke of wheel, space is comparatively tight, and the structural mechanical property that lock body is good, and hydraulic shear is difficult to violence and tears lock open, and security performance is high.

Certainly; just by reference to the accompanying drawings the preferred detailed description of the invention of the utility model is described in detail above; not limit practical range of the present utility model with this; all equivalence changes done according to principle of the present utility model, structure and structure, all should be covered by protection domain of the present utility model.
