Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
As Figure 1-Figure 2, the present embodiment connector, including：Shell 1 and handle 2, the bottom of the shell 1 is provided with
For holding the groove 11 of tow ball 3, the top of the shell 1 offers the passage 12 connected with the groove 11, the drawing
Hand 2 is inserted in the passage 12, and the bottom of the handle 2 is provided with the different globoidal structure 20 of multiple radius of curvature.
Specifically, the present embodiment connector is fixed on trailer by shell 1, and tow ball 3 is to be arranged on traction
Part on car, in actual use, pulled for different tractors to draw on same trailer, different tractors
On the size of tow ball 3 there may be difference, for different tow balls 3,2 bottom of shaking hands is provided with multiple radius of curvature
Different globoidal structure 20, after various sizes of tow ball 3 is arranged in groove 11, by using the cambered surface of different curvature radius
Structure 20 is matched, under being drawn with convenient realization without whole connector is dismantled from trailer.Wherein, in order to
Ensure that the sphere good contact of different globoidal structures 20 and tow ball 3 coordinates, the multiple and cambered surface knot is provided with handle 2
The positioning convex that structure 20 coordinates（It is not shown）, a positioning for being used to coordinate with the positioning convex is provided with the passage 12
Chute（It is not shown）, during insertion handle 2, positioning will be slided into the 20 corresponding positioning convex of globoidal structure chosen
In chute, it just may insure that the globoidal structure 20 and corresponding tow ball 3 are good fit.
Further, in order to more user-friendly, 2 handles 21 for including being connected in turn of shaking hands, connect
Extension bar 22 and positioning head 23, are provided with the globoidal structure 20 and the positioning convex on the positioning head 23, and positioning head 23
Removable to be connected in the connecting rod 22, the connecting rod 22 is rotatably arranged on the handle 21.Specifically, cut
Changing different globoidal structures 20 can be realized by being rotatablely connected bar 22, and because positioning head 23 sets the quantity of globoidal structure 20
Restricted, positioning head 23 uses dismountable mode, and installation can be selected to configure the positioning head 23 of different globoidal structures 20, so as to
It is more beneficial for improving versatility.
By setting the different globoidal structure of multiple radius of curvature, the cambered surface knot of different curvature radius in the bottom of handle
Structure can be engaged with the tow ball of different size, so as to meet that the installation of different tow balls is drawn by a connector
It is required that and user in actual use, without the dismounting and change connector from trailer, it is only necessary to cambered surface knot corresponding to selection
Structure coordinates the requirement that can both meet to be connected installation with tow ball, effectively raises the versatility of connector and improves user's body
The property tested.
As shown in Figure 3-Figure 5, the present embodiment towed vehicle system, including tractor 100 and trailer（It is not shown）, the traction
Tow ball 3, in addition to connector are provided with car, the shell 1 of the connector is fixed on the trailer, the tow ball 3
It is arranged in the groove of the shell 11 and is engaged with the globoidal structure of handle 2 in the connector.Wherein, in order to improve
Theftproof performance, connector also include lock box 4, and the lock box 4 includes the first box body 41 and the second box body 42, first box body 41
One end and the one end of second box body 42 correspond to hinged, described the other end of first box body 41 and described
The other end of two box bodys 42 is respectively arranged with lock nose 43, and lockhole is offered on the lock nose 43（It is not shown）；Described
After one box body 41 and second box body 42 closure, the top of first box body 41 and second box body 42 partly wraps portion
Divide the shell 1, also, the bottom of first box body 41 and second box body 42 wraps leakage outside the shell 1
The tow ball 3.Specifically, connector can use the connector in above-described embodiment, it is of course also possible to use existing skill
Ordinary connector in art, after tractor 100 is connected by connector with trailer, by lockset 4 by the first box body 41 and second
Box body 42 is locked, and can be stolen trailer to avoid connector from being dismantled by others, greatly be strengthened the safe antitheft system of trailer
Number.Wherein, the lock box 4 also includes jam plate 44, and screwed hole is offered on the jam plate 44, and the tow ball 3 is threaded in
In the screwed hole, the jam plate 44, can be more by jam plate 44 between the box body 42 of the first box body 41 and second
Firmly connector is arranged on tow ball 3, improves use reliability.And jam plate 44 is fixed on first box body 41 or institute
State on the second box body 42；Or first be respectively arranged with neck on box body 41 and second box body 42, the jam plate 44 is stuck in
Between two necks.Preferably, after the first box body 41 and second box body 42 close, the lock nose 43 is positioned at described
Between first box body 41 and second box body 42, the longer lock core that can shelter from lockset 4 in bottom of box body, destruction lockset is given
4 increase difficulty, more effectively improve safe antitheft coefficient.
The lock box being made up of two box bodys can wrap up part enclosure and leakage in whole tow balls of shell,
Then, it will lock that nose is locked by lockset, anti-theft protection is carried out to the connecting portion of connector and tow ball so as to realize, and two
Individual box facilitates user's routine use to operate, improves ease of use and security reliability by the way of being articulated and connected.
