Description
Technical field
The utility model is related to a kind of commercial car tow arm.
Background technology
One end of existing tow arm is generally connected on trailer, and the other end is provided with the ball matched with tow ball spherical head
Nest, when trailer drags fault car away from scene, staff needs the tow ball that will be installed on fault car chassis in advance
Spherical head is clamped in ball-and-socket, and during trailer is travelled with fault car, spherical head can be according to the difference of road conditions
There is left and right or swing in ball-and-socket in (such as road surface is uneven).There are two as existing tow ball is first, be divided into up and down
It is plugged on tow arm body, specific connected mode is that a sleeve is installed on tow arm body, and sleeve lining opens up internal thread, and two drag
Car bulb has external screw thread, and two tow ball head threads are connected in sleeve, although the structure can be by two trailer bulbs and tow arm
Body is fixed together, but because two trailer bulbs are solidly plugged in sleeve jointly, therefore in specific installation, it may appear that two trailers
The end of bulb offseted in sleeve against, cause trailer bulb be arranged on tow arm body on trailer bulb on tow arm body
There is the problem of axial motion, stability is poor.
Current existing commercial car trailer arm configuration is insecure, does not assemble easily, without anticreep effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sound construction, easily assembling, with anticreep effect
Commercial car tow arm.
To solve the above problems, the utility model is adopted the following technical scheme that：
A kind of commercial car tow arm, including sleeve pipe, linking arm, connector and screw rod, described sleeve pipe one end is welded with installation
Plate, described linking arm one end is located in sleeve pipe, and the linking arm other end is welded with connector, and the connector is in bend inwards
Set, the connector side is run through by screw rod, and the connector opposite side is provided with free bearing, and the free bearing side is provided with shelves
Bar, the lever middle part is provided with spring, and the screw tip is welded with bulb, and described sleeve pipe outside is provided with latch, described
Latch sequentially passes through sleeve pipe and linking arm, the latch two ends construction opening pin.
Preferably, being provided with mounting hole on the installing plate, installing plate can be fixed on mounting screw on mounting hole
On car body.
Preferably, the rectangular setting of described sleeve pipe section, tow arm section is also rectangular, can be inserted in sleeve pipe.
Preferably, the screw rod bottom is provided with nut, nut can be fixed to screw rod.
Preferably, the split pin runs through latch, latch one end drilling so that split pin can be passed through has to latch
Limited bit function.
Preferably, the both ends of the spring is welded with lever and connector respectively, spring can apply elastic force to baffle plate, make
Obtain lever to be contacted with bulb, can prevent the noose for being enclosed within bulb bottom from slipping.
The beneficial effects of the utility model are：The linking arm of setting is welded with connector, sound construction；Linking arm one end sets
Spacing by latch in sleeve pipe, connector side is run through by screw rod so that structure is easily assembled；The spring of setting can be to gear
Plate applies elastic force so that lever is contacted with bulb, can prevent the noose for being enclosed within bulb bottom from slipping, with anticreep effect.
Brief description of the drawings
Fig. 1 is a kind of structure chart of commercial car tow arm of the utility model.
Specific embodiment
As shown in figure 1, a kind of commercial car tow arm, including sleeve pipe 1, linking arm 2, connector 3 and screw rod 4, described sleeve pipe 1
One end is welded with installing plate 5, and the one end of the linking arm 2 is located in sleeve pipe 1, and the other end of the linking arm 2 is welded with connector 3,
The connector 3 is run through in the setting that bends inwards, the side of the connector 3 by screw rod 4, and the opposite side of the connector 3 is provided with
Free bearing 6, the side of the free bearing 6 is provided with lever 7, and free bearing 6 carries rotating shaft, and lever one end is directly welded at rotating shaft middle part,
The middle part of the lever 7 is provided with spring 8, and extruding lever 7 makes it be contacted with bulb 9.The welded top of the screw rod 4 has bulb 9, institute
State the outside of sleeve pipe 1 and be provided with latch 10, the latch 10 sequentially passes through sleeve pipe 1 and linking arm 2, and correspondence position is drilled
Allow that latch 10 is passed through.The two ends construction openings pin 11 of the latch 10, after installing latch 10, split pin 11 can be to latch
10 carry out it is spacing.Mounting hole 12 is provided with the installing plate 5.The rectangular setting of the section of described sleeve pipe 1.The bottom of the screw rod 4
Nut 13 is installed.The split pin 11 runs through latch 10.Welded with lever 7 and connector 3 respectively at the two ends of the spring 8.
The beneficial effects of the utility model are：The linking arm of setting is welded with connector, sound construction；Linking arm one end sets
Spacing by latch in sleeve pipe, connector side is run through by screw rod so that structure is easily assembled；The spring of setting can be to gear
Plate applies elastic force so that lever is contacted with bulb, can prevent the noose for being enclosed within bulb bottom from slipping, with anticreep effect.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
