Description
Technical field
The utility model is related to aerospace applications equipment technical field, more particularly to a kind of aviation cart.
Background technology
With the continuous development of civil aviaton of China cause, airline is that the service that passenger provides is also more and more comprehensive, mostly
All it can prepare free food and beverage for passenger on number flight, and since space is limited on passenger plane, usual flight attendant makes
Food and beverage are carried with aviation cart, and cart is pushed by flight attendant, food and beverage are provided for passenger.However passenger plane
During flight, encountering air-flow and usually will appear and jolt, when takeoff and landing, passenger plane also will produce shaking, and in cart
Abundance of food and beverage are carried, during jolting and shaking, flight attendant is difficult to stationary carts, although being set on wheel
It is equipped with brake gear, but to improve cargo dead-weight, the usual vehicle body of cart is higher, thus cart is easy to happen rollover, causes cart
Injure passenger or food, beverage pouring by a crashing object with passenger, there is some potential safety problems.
To solve this problem, a kind of peace is disclosed in the Chinese invention patent that application publication number is CN105585585A
Stable aviation cart entirely is equipped with connecting rod in the vehicle body both sides of cart, and the vehicle body junction of connecting rod and cart is equipped with shaft, even
Bar can rotate around the shaft, and the end of each connecting rod is both provided with spring detent, is caught and is used as by spring detent, avoids cart in bottom surface
Upper sliding.
However during actual use, jolting for passenger plane is arrived before with shaking often without omen, and generation is very
Suddenly, it jolts with when shaking in passenger plane, flight attendant is inherently difficult to stand firm, and the aviation cart in the patent needs air-service
Personnel produce around the shaft at this moment, by connecting rod, and spring detent is fixed on nearest seat, since person's development speed has
Limit, it is difficult to above step is completed in time, and cart is fixed, thus its practical function is poor.
Utility model content
The purpose of this utility model is to provide a kind of aviation cart, it is advantageous that, it is safe to use and easy to operate, it is practical
Property is strong.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of aviation cart, including car body, be set to the idler wheel of vehicle bottom and be set on the car body and for locking

It is equipped with pressing plate 431, width of the distance between two pressing plates 431 slightly larger than supporting block 421 and the circumferential surface less than two first support rollers 423
Between maximum distance.The setting of pressing plate 431, on the one hand, the width for minimizing the opening of support slot 43 reduces dust or miscellaneous
Matter enters in support slot 43, also reduces the setting of support slot 43 to being influenced caused by the walking about of passenger；On the other hand, work as passenger plane
When jolting with shaking, cart might have the tendency being detached from out of support slot 43, and pressing plate 431 can be by two first support rollers
423 force to be pressed in support slot 43, to effectively prevent cart disengaging out of support slot 43, or even the dangerous generation of rollover,
Improve stability and the safety of cart.
The top of refer to the attached drawing 5, car body 1 offers the loading slot 12 of rectangle, is equipped in loading slot 12 for holding food
The objective box 13 of object and/or beverage.Objective box 13 is whole also rectangular, there is several plates being equidistantly positioned in objective box 13
131, transverse and longitudinal interlock plate 131 between form several loading lattice 132.Different types of food can be placed in each loading lattice 132,
Classification Management convenient for flight attendant to food.It is circular supporting sleeve 133, support that inner wall is provided in part loading lattice 132
Beverage bottle insertion can be embedded in set 133.The actual quantity of supporting sleeve 133 can be according to the required actual conditions for placing beverage bottle quantity
Depending on, the setting of supporting sleeve 133 and loading lattice 132 can reinforce support of the cart to food or beverage bottle, prevent passenger plane from jolting
During shaking, food or beverage bottle are fallen from cart, injure passenger by a crashing object, improve the safety of cart.
Be provided with damper mechanism 5 between loading slot 12 and objective box 13, damper mechanism 5 include be set to 12 bottom surface of loading slot with
Several first convex blocks 51 on its inner wall, be set on 13 bottom of objective box and its outer wall and with the first convex block 51 corresponding second
It is arranged with compression spring 53 on convex block 52, each first convex block 51 and corresponding second convex block 52, by the support of compression spring 53,
There are certain spaces to form vibration damping area between first convex block 51 and the second convex block 52.
When passenger plane jolts with shaking, the objective box 13 equipped with food and/or beverage, by squeezing compression spring 53, pressure
Elastic deformation occurs for spring 53, the kinetic energy of objective box 13 is converted to the elastic potential energy of compression spring 53, to reduce objective box 13
It shakes, prevents food and/or beverage from being fallen out of objective box 13, injure passenger by a crashing object, improve the safety of cart.First convex block 51
With the setting of the second convex block 52,53 unbalance stress of compression spring can be reduced, bending occurs, tilts the occurrence of even popping up, to carry
The high stability of damper mechanism 5.
Braking mechanism 3 is set to the bottom of car body 1, and braking mechanism 3 includes the pedal 31 for being set to 1 bottom of car body, is passed through
Pushes pedals 31 are, it can be achieved that locking and release to idler wheel 2.Since braking mechanism 3 belongs to the prior art, it will not be described here.
When using cart, cart is pushed to the other side from the side of passenger plane cabin along support slot 43.In the process,
If encountering jolting and shaking for passenger plane, flight attendant only needs to step on the pedal 31 of braking mechanism 3, is locked to idler wheel 2
Fixed, to realize cart locking in the front-back direction, due to the setting of mechanism 4 supported on both sides, branch fastener 42 is embedded in support slot 43
It is interior, to realize the lateral locking of cart；Meanwhile objective box 13 is by the effect of damper mechanism 5, it is therefore prevented that food in objective box 13
And/or beverage is fallen from cart, to improve safety and the stability of cart jointly.
Aviation cart in compared with the prior art, the aviation cart in this patent is more convenient to use, only needs flight attendant
Step on pedal 31 and locking to cart can be realized, it is easy to operate, flight attendant be easy passenger plane jolt with shake in complete it is dynamic
Make, it is highly practical.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
