Description
Technical field
The utility model relates to draw gear, relates in particular to a kind of traction seat.
Background technology
The sanitation cart of prior art is when drawing sewage disposer, on the hook hanging over sanitation cart with rope one end, the other end is connected with towed vehicle draw bar, this mode of traction has following shortcoming, and 1 rope hangs on hook and easily comes off, and 2 need workman's M/C could realize sewage disposer is connected with sanitation cart.
Utility model content
For solving the technical matters that above-mentioned prior art exists, the utility model provides a kind of traction seat, and tractor truck and trailer are not easily thrown off from being dynamically connected, moreover remote controlled unhook.
The technical solution adopted in the utility model is: provide sanitation cart traction seat, the bearing pin comprise permanent seat, fixing with permanent seat, the rotation seat, the spring that are rotationally connected with bearing pin, described spring one end is connected with permanent seat, the other end is provided with thimble, described permanent seat is provided with upper lip block and the lower lip block relative with upper lip block, described upper lip block and lower lip block are respectively equipped with the first spigot surface and the second spigot surface, described lower lip block is provided with the first storage tank, described rotation seat is provided with the second storage tank, and described rotation seat is provided with the 3rd spigot surface.
Described first spigot surface, the second spigot surface, the 3rd spigot surface are respectively cambered surface or inclined-plane.
During work, sanitation cart is close to sewage disposer, namely towed vehicle draw bar and traction seat close, by the guiding of the first spigot surface and the second spigot surface, towed vehicle draw bar is gradually near the 3rd spigot surface, because the 3rd spigot surface is inclined-plane or arc surface, in the process that towed vehicle draw bar is moved to the left, to rotation seat applied thrust, the elastic force making rotation seat overcome spring rotates clockwise, the right-hand member of rotation seat and permanent seat are thrown off, towed vehicle draw bar is entered the first storage tank, then driving thimble promotion rotation seat to rotate counterclockwise at spring makes rotation seat and permanent seat again fasten, be positioned in the region that the first storage tank and the second storage tank surround by towed vehicle draw bar, towed vehicle draw bar is made to depart from traction seat.
The utility model guides the movement of towed vehicle draw bar by arranging spigot surface, the zone location making towed vehicle draw bar enter the first storage tank and the second storage tank to surround, realizes towed vehicle draw bar and traction seat locates the object of not easily throwing off automatically.
As improvement, the left end of described rotation seat is provided with circular arc projection, and such advantage is that thimble offsets with circular arc projection all the time when rotation seat rotates, and makes rotation seat stressed more balanced, rotates more steady.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1 permanent seat, 2 springs, 3 thimbles, 4 bearing pins, 5 rotation seats, 6 towed vehicle draw bars, 7 upper lip blocks, 8 lower lip blocks, 9 first spigot surfaces, 10 second spigot surfaces, 11 first storage tanks, 12 second storage tanks, 13 the 3rd spigot surfaces.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
A kind of traction seat, comprise permanent seat 1, the bearing pin 4 fixing with permanent seat 1, the rotation seat 5, the spring 2 that are rotationally connected with bearing pin 4, described spring 2 one end is connected with permanent seat 1, the other end is provided with thimble 3, described permanent seat 1 is provided with upper lip block 7 and the lower lip block 8 relative with upper lip block 7, described upper lip block 7 is respectively equipped with the first spigot surface 9 and the second spigot surface 10 with lower lip block 8, described lower lip block 8 is provided with the first storage tank 11, described rotation seat 5 is provided with the second storage tank 12, and described rotation seat 5 is provided with the 3rd spigot surface 13.
Described first spigot surface 9, second spigot surface 10, the 3rd spigot surface 13 are respectively cambered surface or inclined-plane.
During work, tractor truck is close to towed vehicle, namely towed vehicle draw bar 6 is close with traction seat, by the guiding of the first spigot surface and the second spigot surface, towed vehicle draw bar 6 is gradually near the storage tank back side, because the storage tank back side is inclined-plane or arc surface, in the process that towed vehicle draw bar 6 is moved to the left, to rotation seat 5 applied thrust, the elastic force making rotation seat 5 overcome spring 2 rotates clockwise, the right-hand member of rotation seat 5 and permanent seat 1 are thrown off, towed vehicle draw bar is entered storage tank, then drive thimble 3 to promote rotation seat 5 at spring 2 to rotate counterclockwise rotation seat 5 and permanent seat 1 are fastened again, be positioned in the region that the first storage tank and the second storage tank surround by towed vehicle draw bar, towed vehicle draw bar 6 is made to depart from traction seat.
The utility model guides the movement of towed vehicle draw bar 6 by arranging spigot surface, the zone location making towed vehicle draw bar enter the first storage tank to surround with the second storage tank, realizes the object that towed vehicle draw bar 6 is not easily thrown off with the automatic location of traction seat 1.
During dislodging, only need pull control line pull head gently on seat, traction seat rotation seat 5 rotates clockwise, upperlip opened with certain angle, and draw bar comes off naturally, unclamps control line pull head, and traction seat upperlip closes up naturally.
As improvement, the left end of described rotation seat 5 is provided with circular arc projection, and such advantage is that thimble 3 offsets with circular arc projection all the time when rotation seat 5 rotates, and makes rotation seat 5 stressed more balanced, rotates more steady.
Be described with regard to the utility model preferred embodiment above, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change, and all various changes done in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
