Abstract
The invention discloses a through passage tightening pull rod assembly in a bus transport process, and relates to the field of passenger vehicle through passage design. The through passage tightening pull rod assembly comprises a locating ring, a locating seat, two fixing clips and a tightening pull rod. The locating ring is fixed on a screw frame of a vehicle through passage, and the locating seat is fixed on a connection frame of the vehicle through passage. The tightening pull rod is composed of a rotating handle and two pull rod bodies, wherein inner threads are arranged at the two ends of the rotating handle, one ends of the two pull rod bodies are respectively provided with a hook, the other ends of the two pull rod bodies are both provided with outer threads, the rotating handle and the two pull rod bodies are connected through the threads, and the space between the two pull rod bodies is increased or decreased by the way of matching of the inner threads and the outer threads. According to the through passage tightening pull rod assembly in the bus transport process, a tightening pull rod structure is adopted, the hooks at the two ends are hung on the screw frame and the connection frame of the through passage respectively, so that the through passage in an unfastening state is lifted, tightened and limited, and therefore the through passage can be protected from being damaged caused by bumping or abrading in the bumpy bus transport process.
Description
Technical field
The present invention relates to subway vehicle run-through channel design field, the run-through channel be specifically related in a kind of automotive process tightens up rod assembly.
Background technology
Split type run-through channel is the link of a kind of extensible, the compression between two compartments of subway vehicle, and it is used to form safe interface channel makes the passenger current.When via the split type run-through channel of Automobile Transportation, need to make run-through channel in separating the volume state, now, run-through channel one end is to be fixed on carbody by crew cabin, the free state of the connection box of the other end in not connecting, run-through channel under this kind of state can, because have very large degree of freedom without any tightening up anchor fitting, be easy to because being collided with in the transportation of jolting or wearing and tearing, and then cause damage.
Summary of the invention
For solve that existing split type run-through channel exists by Automobile Transportation the time without any tightening up anchor fitting, it is in separating under the volume state, easily because being collided with or wearing and tearing, cause the technical matters of damage in the transportation of jolting, the run-through channel the invention provides in a kind of automotive process tightens up rod assembly.
The technical scheme that technical solution problem of the present invention is taked is as follows:
Run-through channel in the automotive process tightens up rod assembly and comprises steady ring, positioning seat, two fixed cards and tighten up pull bar, and steady ring is fixed on the crew cabin of vehicle run-through channel, and positioning seat is fixed on the connection box of vehicle run-through channel; Tightening up pull bar is comprised of turning handle and two pull bars, the two ends of turning handle are provided with negative thread, and an end of two pull bars is equipped with a hook, and the other end is equipped with outside thread, turning handle and two pull bars are threaded connection, and the spacing of two pull bars increases or dwindles by the cooperation of internal and external threads; Two fixed cards all are fixed on the midway location of the crew cabin of vehicle run-through channel, and two fixed cards are setting up and down, and the spacing of the two is more than or equal to the entire length of turning handle.
Described steady ring is fixed on the top position, centre of crew cabin, and the centre that positioning seat is fixed on connection box is position on the lower.
The invention has the beneficial effects as follows: adopt and tighten up Tiebar structure; utilize the hook at its two ends to be hung on the crew cabin and connection box of run-through channel; by separate run-through channel under the volume state lift and tighten up spacing, thereby the protection run-through channel can not cause damage because being collided with or wearing and tearing in the automotive process of jolting.
The accompanying drawing explanation
Fig. 1 is that the run-through channel in automotive process of the present invention tightens up the schematic diagram of rod assembly under the use state;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 tightens up the Tiebar structure schematic diagram in the present invention;
Fig. 4 is that the run-through channel in automotive process of the present invention tightens up the schematic diagram of rod assembly under unused state;
Fig. 5 is the B-B section-drawing of Fig. 4.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figures 1 to 5, run-through channel in automotive process of the present invention tightens up rod assembly and comprises steady ring 1, positioning seat 2, two fixed cards 3 and tighten up pull bar 4, steady ring 1 is fixed on the top position, centre of the crew cabin 5 of vehicle run-through channel, and positioning seat 2 is fixed on the position on the lower, centre of the connection box 6 of vehicle run-through channel.
Tightening up pull bar 4 is comprised of turning handle 4-1 and two pull bar 4-2, the two ends of turning handle 4-1 are provided with negative thread, the end of two pull bar 4-2 is equipped with a hook, the other end is equipped with outside thread, turning handle 4-1 and two pull bar 4-2 are threaded connection, and the spacing of two pull bar 4-2 increases or dwindles by the cooperation of internal and external threads.
Two fixed cards 3 all are fixed on the midway location of the crew cabin 5 of vehicle run-through channel, and two fixed cards 3 are setting up and down, and the spacing of the two is more than or equal to the entire length of turning handle 4-1.
When via the Automobile Transportation run-through channel, the residing end of run-through channel connection box 6 in separating under the volume state can acutely wave with automobile bumpiness, therefore can apply run-through channel of the present invention and tighten up rod assembly its degree of freedom is used restraint and fixes.
As shown in Figure 1; at first; connection box 6 is lifted and push towards crew cabin 5; the flexible canopy cloth integral body of run-through channel is tightened up, then rotate turning handle 4-1, the spacing between two pull bar 4-2 is increased gradually; until the hook at two pull bar 4-2 two ends can be hung on steady ring 1 and the bearing pin of positioning seat 2 on; complete to run-through channel lift and tighten up spacing, thereby the protection run-through channel in the Automobile Transportation process of jolting, can not cause damage because being collided with or wearing and tearing.
When run-through channel keeps spacing and the spacing state of constraint without continuation, at first the hook at two pull bar 4-2 two ends is taken off from the bearing pin of steady ring 1 and positioning seat 2 respectively, then rotate turning handle 4-1, make the spacing between two pull bar 4-2 be decreased to gradually the limit, respectively by not having threaded connecting rod position to snap in two fixed cards 3 on two pull bar 4-2, can by tightening up pull bar 4, be fixed on reliably on the sidewall of crew cabin 5 like a cork again.
