Abstract
The present invention relates to a kind of car trailer coupler lock, the locking bar including lock body, being arranged on lock body and lock core, one end of described locking bar is flexibly connected with lock body, and the other end of described locking bar is connected with lock body lock by lock core, and the middle part of described lock body upper surface is fixedly connected with bonding jumper.The invention have the benefit that simple in construction, product is elegant in appearance, it is simple to carry, and accessory will not be lost, and overall cost is lower.
Description
Technical field
The present invention relates to the locking device of car trailer coupler, particularly relate to a kind of car trailer coupler lock.
Background technology
Car trailer coupler lock is that the main deficiency of existing car trailer coupler lock is for the locking device that trailer ball cover is fixing: 1) lock body is provided with the chondritic of circle, and its structure is too fat to move, and volume is big, and weight is big, and cost is high；2) becket of existing car trailer coupler lock and lock body are detachable connections, and during this mode result in use, becket is easily lost；3) due to split and locking mode, need two handss to take when operation simultaneously.
Summary of the invention
A kind of car trailer coupler lock that the present invention provides, to solve, the structure of prior art is too fat to move constant carries, and accessory easily loses the weak point with bimanualness.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
A kind of car trailer coupler lock, the locking bar including lock body, being arranged on lock body and lock core, one end of described locking bar is flexibly connected with lock body, and the other end of described locking bar is connected with lock body lock by lock core.
Further, the middle part of described lock body upper surface is fixedly connected with bonding jumper.
Preferably, the side of described lock body is provided with opening, and described locking bar is rotationally connected with lock body by the fixing axle in opening.Described locking bar is connected with lock body lock by tooth-shape structure.
Preferably, bonding jumper is circular arc.
Preferably, the side of lock body is provided with opening, and described locking bar is rotationally connected with lock body by the fixing axle in opening.
Preferably, locking bar is connected with lock body lock by tooth-shape structure.
Preferably, the locking of lock core is handcuff-type locking.The size gap of lock tooth is fine and closely woven, it is simple to the multiformity of locked position.
Preferably, locking bar is arc-shaped, oval arcuation or a combination of both, is similar to petal-shaped, more agrees with trailer by the profile of latching segment.Thus there is more preferable locking effect.
The present invention is flexibly connected with lock body by locking bar one end, the other end is connected with lock body lock, ensureing that becket will not be lost, the implication of described flexible connection still between the two can be with relative motion for being connected for non-dismountable formula between use hour locking lever and lock body, such as rotation etc..On the other hand change existing ball into bonding jumper, make overall structure the most succinct.
The invention have the benefit that simple in construction, product is elegant in appearance, it is simple to carry, and accessory will not be lost, and overall cost is lower.

Fig. 3 is the use state diagram of car trailer coupler lock of the present invention.
In figure:
1, lock body；2, bonding jumper；3, lock core；4, locking bar；5, tooth-shape structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is specifically described, it will be appreciated that accompanying drawing only represents the one of which of the present invention and is embodied as situation, is not intended to limit the present invention.
As it is shown in figure 1, a kind of car trailer coupler lock described in the embodiment of the present invention, the locking bar 4 including lock body 1, being arranged on lock body 1 and lock core 3, one end of described locking bar 4 is flexibly connected with lock body 1, and the other end of affiliated locking bar 4 is connected with lock body 1 lock by lock core 3.The middle part of described lock body 1 upper surface is fixedly connected with bonding jumper 2.
The car trailer coupler lock that the present invention provides, preferred embodiment sees accompanying drawing 1-3, it is rotationally connected with lock body 1 by locking bar 4 one end, the other end is connected with lock body 1 lock by tooth-shape structure 5, during use, unclamped by lock core 3 or lock tooth-shape structure 5, so that locking bar 4 is decontroled or fixed car trailer ball cover.But the invention is not limited in above preferred embodiment, one end that locking bar 4 formula non-dismountable with lock body 1 is connected can also is that the connection of upper and lower slidingtype or other conventional mechanical motion mode, one end that locking bar 4 is connected with lock body 1 lock is also not limited to tooth-shape structure 5, the structures such as draw-in groove, groove, projection also can, only need to pin.
The car trailer coupler lock that the present invention provides, chondritic heavy in prior art is modified to metal strip structure, the implication of described list structure refers to that its length is more than width, the cross section not limiting this bonding jumper 2 can be circle, rectangle, ellipse and other geometries as rectangle, the cross section of described bonding jumper 2.Additionally, stablizing time in prior art in order to lock, employ the spherical shape matched with trailer ball cover Internal Spherical Surface and limit device, thus ensure that locking trailer can not move forward and backward, after the present invention changes bonding jumper 2 into, preferably require in size that the end of bonding jumper 2 is pressed on the inwall that trailer ball cover is anterior, buckle in the external rear face of trailer ball cover with the radian upwards dug with hour locking lever 4, ensure that locking trailer ball cover can not move forward and backward the most equally, and this design also limit the rotation of trailer ball cover simultaneously, and prior art can not limit it and rotate.The present invention is also obtained extra technique effect while succinct structure reduces cost.
