Abstract
The invention discloses a kind of expansible tow arm, belonging in technical field of vehicle is used for breakdown trailer, fault motor vehicle, while for emergency management and rescue.It is a kind of with extension elongation is short, can install, change expanded function part (utility function or decoration functions its object is to provide）, high intensity tow arm with certain anti-theft feature, landscaping effect.Including principal arm, saddle, extension, mounting flange.Principal arm is blocked provided with sunk type shirt rim to the installation parts of saddle, extension, it is therefore prevented that common dismounting of the extracting tool to trailing arm member, serves antitheft, beautification function while also increasing arm body intensity.
Description
Technical field
The invention belongs to machine design and manufacture technical field, especially belong to motor vehicle fittings design and led with manufacturing technology
Domain, more particularly to a kind of expansible tow arm for drawing and rescuing for motor vehicle.
Background technology
Tow arm is that a kind of one end is directly fixed on motor-vehicle chassis draw-bar or special on draw-bar by inserting
Fast interface and be connected on motor vehicle, the other end with specific saddle, play the suspension member of connection function.It is mainly used in connection
With breakdown trailer, fault motor vehicle and other need the article that draws, hang.
The patents such as Publication No. CN205930071U, CN203739561U individually disclose the push-in tow arm of correlation.
Above two patent be by insert the special fast interface on motor vehicle draw-bar and be connected to motor vehicle it
On.But, this type patented technology has following problem：Arm body stretching motor vehicle rear is long, influence reversing stopping distance anticipation；
Easily pedestrian is caused to collide with after parking in public arena；It can not hang, change outer suspension member such as：Function Extension part, individual character decorating mask
Deng；Without part anti-theft capability and landscaping effect.
The content of the invention
It is an object of the invention to：The problem of existing for prior art there is provided a kind of extension elongation it is shorter, can install more
Change the outfit decorations or expanded function part, the tow arm with certain anti-theft feature and landscaping effect.
The present invention is achieved through the following technical solutions：
A kind of expansible tow arm, including arm body, extension, the saddle of arm body front end（Can be standard hauler ball, 3/4U shape hooks
Ring, ram's horn etc. be general or other special saddles）, it is characterised in that：The arm body rear end is additionally provided with mounting flange, the peace
Dress flange is provided with four screws and installs via, and the arm body is screwed in motor vehicle trailer thick stick by mounting flange
On, the extension is screwed in arm body front end, and the saddle is sequentially passed through by its screw rod is arranged at arm body front portion
The saddle of upper surface installs via, spring washer, antitheft gasket ring, and installing nut with saddle is anchored on arm body.
The antitheft gasket ring side of saddle is provided with adjustable anti-theft screw, and extension screw is pushed against in the mounted state, is made
Obtain extracting tool directly can not dismantle to arm body front end extension.
The arm body front portion is provided with sunk type shirt rim, has covered the installation securing part of saddle and extension and has included phase
Extension screw, saddle screw rod, saddle nut, spring washer, antitheft gasket ring for answering etc., while also blocking common extracting tool
The extension, saddle component are dismantled.
The beneficial effects of the invention are as follows：
In the present invention, the arm body installs screw with arm body by the mounting flange of its rear end and is directly installed on motor vehicle trailer
On thick stick, the special square opening slotting soon on draw-bar is eliminated, entire length is significantly reduced.It is convenient to move backward, on the ground of limited space
Side's parking, protection pedestrian.
In the present invention, the arm body front end is provided with dismountable extension, realizes tow arm function, outward appearance individual character many
Sample feature.
In the present invention, because saddle screw rod, antitheft gasket ring, the anti-theft screw of antitheft gasket ring, saddle nut are to extension spiral shell
Silk stops so that extracting tool is not directly dismantled to extension.Further, there is sunk type arm body the arm body front portion
Shirt rim, having blocked the installation securing part of saddle and extension includes corresponding extension screw, saddle screw rod, saddle spiral shell
Mother, spring washer, antitheft gasket ring etc. so that common extracting tool can not be dismantled to the extension, saddle component, only
Special sleeve tool for same is just detachable, plays certain anti-theft function, further, serves the effect of aesthetic appeal, while
Increase the bulk strength of trailing arm.

Embodiment
The present invention is specifically described below by embodiment, the present embodiment is served only for carrying out further the present invention
Explanation, but it is not intended that limiting the scope of the invention, those skilled in the art is according in the invention described above
Hold some the nonessential modifications and adaptations made and fall within the scope of protection of the invention.
With reference to Fig. 1 to Fig. 6.
A kind of expansible tow arm, as illustrated, including：Arm body 1, for installing each functional unit, saddle 2 is used to lay
Different traction appliances are connected with by traction object, extension 3, for individual character displaying and the additional work(extension of trailing arm.
Mounting flange 11, installs screw 4 by arm body, is fixed on whole arm body 1 through flange screw via 111 motor-driven
On car rear dragging thick stick.
Extension 3, by extension screw 31, enters extension through the extension screw via 14 of arm body 1 and installs spiral shell
Inside hole 32, the front end of arm body 1 is fixed in.
Saddle 2, the saddle of its screw rod 21 through arm body 1 installs via 13, and with this through saddle spring washer 24, antitheft
Gasket ring 23, installs nut 22 with saddle and saddle 2 is anchored on arm body 1.
The antitheft side of gasket ring 23 is provided with gasket ring anti-theft screw 231, is in and is installed under tightening state in saddle 2, and gasket ring is prevented
Steal the head of screw 231 and push against extension screw 31 so that extracting tool can not be dismantled directly to extension 3, to extension 3
Serve certain anti-theft function.
In the mounted state, spinning stop pin 26 is placed in the spinning stop pin counterbore 15 of arm body 1, and its top enters stopping for saddle 2
Revolve inside cotter way 25, prevent rotation of the saddle 2 during installation, use.
Arm body shirt rim 12 to the installing component of saddle 2 and extension 3 effectively block, it is therefore prevented that common extracting tool
The robber of trailing arm parts is torn open, visual landscaping effect is also played, while also increasing the bulk strength of trailing arm.
