Description
Technical field
The invention belongs to hook technology field, more particularly, to a kind of anti-dropout draw-gear.
Background technology
One or more tractor is generally required in larger warehouse area mobile cargo and loads goods, in order to tractor is connected
Facilitate dragging together, connected the tractor to together using traction hook, traction hook now includes preposition hook dress
Put with rearmounted hooking device, preposition hooking device and rearmounted hooking device are separately positioned on the front and rear of tractor, preceding
Putting hooking device includes fixed seat, rotating shaft and swing hook, and fixed seat is provided with slotted eye, in swing hook insertion slotted eye, rearmounted hook
Device includes secure u-shaped member, sleeve pipe and connector, and sleeve pipe is set in secure u-shaped member, and sleeve pipe and connector are fixed and connected
Connect, connector is provided with connecting hole.
Existing traction hook structure is complicated, and operation inconvenience, rotating shaft is fixedly connected with swing hook, and rotating shaft connects with fixed seat activity
Connect, swing hook now is the straight-bar being welded in rotating shaft, the situation for low-angle deviation occur is easy in welding, it is this
Low-angle deviation naked eyes difficulty is shown in, but swing hook is passed in and out slotted eye and had some setbacks, and is had a strong impact on and is used.
The content of the invention
The invention aims to overcome prior art not enough, there is provided a kind of anti-dropout draw-gear, simple structure, behaviour
Make fix stably when convenience, connection.
The technical scheme is that：A kind of anti-dropout draw-gear, including U-shaped connecting seat, attachment means and fixed dress
Put, link slot is respectively arranged with the relative both sides pedestal of the U-shaped connecting seat, the attachment means include connecting plate
And connecting bracket, the rear end of the connecting bracket is fixedly connected with connecting plate, and the connecting plate coordinates with link slot grafting,
The fixing device includes U-shaped fixed seat, sleeve pipe and fixture, divides on the relative both sides pedestal of the U-shaped fixed seat
Grooved hole is not set, and described sleeve pipe is oppositely arranged on the both sides of slotted eye, between described sleeve pipe rotate be connected to grafting consolidate
Surely the fixture of front edge of board is connected.
Further, the front end of the connecting bracket is circular shape.
Further, described sleeve pipe is fixed on the outer surface of side pedestal of U-shaped fixed seat.
Further, it is connected with fix bar in the connecting bracket relative inner.
Further, it is also associated with swing hook on the fixture.
The present invention has the advantages and positive effects that：Due to using above-mentioned technical proposal, connecting plate is plugged on U-shaped company
On link slot on joint chair, support front end is being fixedly connected by fixture grafting, operated conveniently, fixed during connection
It is firm.

Specific embodiment
The present invention is elaborated below in conjunction with the accompanying drawings.
If Fig. 1-Fig. 2 is that shown in structural representation of the invention, the present invention provides a kind of anti-dropout draw-gear, including U
Type connecting seat 1, attachment means and fixing device, the company of being respectively arranged with the relative both sides pedestal of the U-shaped connecting seat 1
Access slot 2, the attachment means include connecting plate 3 and connecting bracket 4, and rear end and the connecting plate 3 of the connecting bracket 4 are consolidated
Fixed connection, the connecting plate 3 coordinates with the grafting of link slot 2, and the fixing device includes U-shaped fixed seat 5, sleeve pipe 6
With fixture 7, grooved hole 8 is respectively provided with the relative both sides pedestal of the U-shaped fixed seat 5, described sleeve pipe 6 is relative
The both sides of slotted eye 8 are arranged on, the fixture 9 for being connected to the front end of grafting fixed connecting plate 3 is rotated between described sleeve pipe 6.
The front end of the connecting bracket 4 is circular shape.Fix bar 10 is connected with the relative inner of the connecting bracket 4.
Described sleeve pipe 6 is fixed on the outer surface of side pedestal of U-shaped fixed seat 5.It is also connected with the fixture 9
There is swing hook 11.
The course of work of this example：The present invention provide anti-dropout draw-gear when in use, respectively by the He of U-shaped connecting seat 1
U-shaped fixed seat 5 is welded on the rear end of tractor and the front end of tractor, and the connecting plate 3 of attachment means is inserted into link slot
In 2, the structure of link slot 2 is elongate in shape, and intermediate width is more than upper end, so in 3 horizontal positioned of connecting plate, no
Groove 2 can be disconnected, then rotational fixture 9, its lower end edge slotted eye 8 is upturned, by the front end of connecting bracket 4
U-shaped fixed seat 5 is sent into, rotational fixture 9 will be fixed in the front end of its lower end insertion connecting bracket 4.
Fix bar 10 is connected with the relative inner of the connecting bracket 4, the fixing intensity of connecting bracket 4 is improve, in institute
State and swing hook 11 is also associated with fixture 9, it is easy to operate by operating swing hook 11 come rotational fixture 9.
One embodiment of the present of invention has been described in detail above, but the content is only presently preferred embodiments of the present invention,
It is not to be regarded as limiting practical range of the invention.All impartial changes made according to the present patent application scope and improvement etc.,
All should still belong within patent covering scope of the invention.
