Description
Technical field
The invention belongs to fire fighting device technical fields, and in particular to a kind of side compartment door linkage headstock gear of fire fighting truck.
Background technology
As the industry's knowledge of the reason, all kinds of disaster relief equipment such as generator, water are usually placed in the car body of fire fighting truck
Pump and various break-in tools etc. take various devices after responding and after arriving at disaster relief scene for the ease of fire fighter
Material needs in time quickly to open the side compartment on left side and/or right side door.And when disaster relief task is completed and by various equipment
After return, and need to close at side compartment door.
Previously, offside compartment door be turned on and off by fire fighter manual operations, not only increase fire fighter work
Amount, and occupy the quality time of fire fighter.
The compartment door linkage open-close device that utility model Authorization Notice No. CN201024817Y recommends using two sets each other
The lanar four rod mechanism of linkage can realize that one-off is fanned door by upper and lower two while being turned on and off.However it still remains
Following shortcoming：First, in the on state, two sets of lanar four rod mechanisms can take fire fighter equipment and generate certain do
It relates to (obstruction)；Second, since two sets of lanar four rod mechanisms are remained each other in connecting state, upper and lower compartment door
Unlatching amplitude be restricted；Third, the balance for being turned on and off action is difficult to ensure.
" the side compartment door linkage mechanism for opening/closing of fire fighting truck " that invention patent mandate notification number CN101967929B is introduced makes up
The shortcoming of above-mentioned CN201024817Y and following technique effect in the 0014th section of record of its specification is objectively fulfilled：
When drag outward draw lower compartment door when, one-time action can open upper and lower compartment door simultaneously, and vice versa；All parts are with equipment
It erects column for carrier to be arranged, therefore there is no generate interference situations when holding with equipment fire fighter after unlatching；Upper and lower compartment door
Unlatching amplitude is big；Stationarity when opening and closing upper and lower compartment door is good.But the patent still remains following deficiency：First, in order to be arranged
Carriage, thus an equipment is returned into column and is arranged in the middle position of compartment chamber accent, erecting column just because of the equipment exists
The presence of compartment chamber accent middle position, to still will produce certain interference effect to taking fire-fighting equipment；Second, upper and lower compartment
After door is opened, foot pedal can not be played the role of by the lower compartment door for drooping or dropping, thus fire fighter enters compartment chamber and takes
It is relatively laborious to put fire-fighting equipment；Third, since the structure of entire open-shut linkage mechanism is complex, thus whether to manufacture,
Assembly or maintenance used in everyday are relatively cumbersome.
In view of above-mentioned prior art, still there is further improved necessity, the applicant has made positive and beneficial set thus
Meter, forms technical solution described below finally.
Invention content
Task of the invention lies in provide a kind of to help to ensure that the equipment chamber accent in equipment compartment is unobstructed and uses satisfaction
Fire fighter steps on taking the convenient requirement of fire-fighting equipment to equipment chamber, be conducive to make the lower compartment door in open state to develop into
Sole and using reduce physical demands of fire fighter when picking and placeing fire-fighting equipment to equipment chamber, be beneficial to significantly to simplify structure and by
With facilitate manufacture and assembly and embody good economy and reduce routine use in maintenance difficulties fire fighting truck side
Compartment door linkage headstock gear.
The task of the present invention is in this way to complete, a kind of side compartment door linkage headstock gear of fire fighting truck, the fire-fighting
Vehicle includes the equipment compartment carriage body for having equipment chamber, in the front side of the equipment compartment carriage body and/or rear side and corresponding to equipment chamber
The position of accent be equipped on one compartment door and once compartment door, the side compartment door linkage headstock gear includes a connecting rod, one slides
Block, once compartment door haulage gear and the once passive traction piece of compartment door, the right side edge position of one end of connecting rod and the upper compartment door
Connection, and the upper end of the other end of connecting rod and sliding block connects, sliding block, which slides up and down to, to be arranged on the right chamber wall of the equipment chamber,
Lower compartment door haulage gear is connected between the lower end of sliding block and the right side edge position of the lower compartment door, the passive traction piece of lower compartment door
It is connected between the left chamber wall of equipment chamber and the left side edge position of lower compartment door, when the upper compartment door and lower compartment door are in and close
When state, shield is covered to the accent of the equipment chamber by upper compartment door and lower compartment door jointly, and when upper compartment door and lower compartment door are in
When open state, lower compartment door is in horizontality and develops into foot pedal.
The present invention a specific embodiment in, the equipment chamber right lower quadrant and corresponding to the sliding block
Position offer a sliding block sliding cavity, the sliding block, which slides up and down to, to be arranged in the sliding block sliding cavity.
In another specific embodiment of the present invention, fixed with longitudinal state on the sliding block sliding cavity bottom wall
There is a slide block guide rail, one sliding block sliding groove, the sliding block are offered with longitudinal state towards the side of slide block guide rail in the sliding block
Sliding groove is slidably matched with slide block guide rail.
In another specific embodiment of the present invention, a connecting rod is fixed at the right side edge position of the upper compartment door
Hinged seat is fixed with a connecting rod connecting seat in the upper end of the sliding block and towards the side of the equipment chamber, the connecting rod
One end is hinged by connecting rod hinging pin shaft and connecting rod hinged seat, and the other end of connecting rod is connected by pitman pin and connecting rod connecting seat
It connects.
In another specific embodiment of the present invention, the right chamber wall composition of the equipment chamber has a right chamber wall separate space,
The lower compartment door haulage gear is connected to the lower end of the sliding block and the lower compartment door in the lower part corresponding to right chamber wall separate space
Between right side edge position.
Of the invention there are one in specific embodiment, lower compartment door haulage gear includes compartment door active
Traction piece guide wheel and once compartment door active traction piece, lower compartment door active traction piece guide wheel are rotatably arranged at described by guide wheel shaft
Right chamber wall separate space in, one end of lower compartment door active traction piece is connect with the lower end of the sliding block, lower compartment active traction piece
