Abstract
Disclosed is a railway vehicles seat lower cover plate quick disassemble and assemble mechanism. The railway vehicles seat lower cover plate quick disassemble and assemble mechanism is characterized in that seat lower cover plate lifting lugs are welded on a seat frame. Rectangular-shaped holes are installed on the seat lower cover plate and the lifting lugs. The seat lower cover plate is installed through a square quick ball lock pin. One head of the quick ball lock pin is provided with chamfers and the middle of the quick ball lock pin is provided two elastic clips for fixing. The railway vehicles seat lower cover plate quick disassemble and assemble mechanism achieves the quick disassemble and assemble structure of the seat lower cover plate by canceling a quick ball lock pin base and using the square quick ball lock pin and the like. In the process of installment, the chamfers on the head of the quick ball lock pin are used for leading and ensure that the quick ball lock pin can correctly slide in the rectangular-shaped holes on the lifting lugs through the seat lower cover plate. After the quick ball lock pin slide in the rectangular-shaped holes, the base lower cover plate can be lifted to the lifting lugs through the two elastic clips for fixing. The tail portion of the ball lock pin is large and is used for tightly clamping the base lower cover plate. When a user detaches the quick ball lock pin, the user only needs to insert a bolt driver into an opening hole of the end, spins and opens the elastic clips, pulls out the base lower cover plate and the quick ball lock pin. Therefore situations that losing of the quick ball lock pin caused by a plurality of reasons are reduced.
Description
Technical field
The utility model relates to cover plate fast assembling disassembling structure under a kind of track carriage seat.
Background technology
Cover plate is installed and is all used fast locking pin seat to accelerate the lock pin pin structure under the existing seat, and namely fast locking pin seat quickening lock pin is followed closely the supporting supply of material, during installation pin is pulled down, and key seat is installed first, fast lock pin nail is installed, fixedly seat lower cover plate after seat lower cover plate installs.
Because fast locking pin seat is Split type structure with fast lock pin nail, size is difficult to control in fast locking pin seat (hardware is similar to clip) installation process, often occur because of the large pin that causes of fast locking pin seat installation deviation can't normal mounting etc. problem.And fast lock pin nail (cylindrical) is the screw-in structure, and easily loosening, loosening, the abnormal sound of cover plate under the seat can appear in fastening seat lower cover plate in the car operation process well, and fast lock pin nail such as loses at the problem.
The utility model content
Technical problem to be solved in the utility model is to use a kind of structure that can Fast Installation seat lower cover plate, is satisfying fast assembling-disassembling, fixedly in the seat lower cover plate, is reducing fast lock pin that a variety of causes causes and follow closely and lose.
For solving the problems of the technologies described above, the utility model provides cover plate fast assembling disassembling structure under a kind of track carriage seat, it is characterized in that: at cushion frame welding seat lower cover shell lug, open oblong aperture at seat lower cover plate and hanger, cover plate is installed by square fast lock pin nail under the seat, fast lock pin nail head is provided with chamfering, and the centre is established two and is used for fixing Spring Card.
The utility model is finished the structure of cover plate under a kind of fast dismounting seat by modes such as the fast locking pin seat of cancellation, the fast lock pin nails of use square.The chamfering of fast lock pin nail head plays guiding function during installation, makes fast lock pin nail can be correctly slip into oblong aperture on the hanger by cover plate under the seat.After pin slips into, use two fixing spring cards with on the cover plate hanger under the seat, afterbody is used for more greatly chucking seat lower cover plate.Only need to insert with screwdriver the hole of opening of afterbody during dismounting, the Unscrew Spring Card is pulled out cover plate under the seat and to be got final product with fast lock pin nail,
The fast lock pin nail that the minimizing a variety of causes causes is lost.
Description of drawings
Fig. 1 is the utility model side cover plate hanger and rubber pad scheme drawing;
Fig. 2 is the utility model seat cover plate perforate scheme drawing;
Fig. 3 is the fast lock pin nail of the utility model scheme drawing.
The specific embodiment
With reference to Fig. 1,2,3, at cushion frame welding seat lower cover shell lug 1, contact surface adhesive rubber pad 2 on the hanger, avoid bad contact, produce noise in the operation, open oblong aperture at seat lower cover plate 3 and hanger 1, oblong aperture is along the car body longitudinal direction on the cover plate under the seat, and oblong aperture is along the cross-car direction on the seat lower cover shell lug.Four direction had the adjustment amount of 9mm when fast lock pin nail was installed, and can satisfy the installation needs fully.Fast lock pin is followed closely the chamfering that 4 heads are provided with C6, and the centre is established 2 and is used for fixing Spring Card 5.
Installation process: seat lower cover plate is installed after cushion frame, chair mounted are finished.The hanger of cushion frame both sides at first is installed; Then seat lower cover plate is installed; Adjust seat lower cover Board position, fast lock pin nail is pressed in the mounting hole of hanger (having the Spring Card side to aim at square hole on the cushion frame hanger) and finishes installation.
Fast lock pin nail head is less, has the heart function of suffering from one's own actions, and utilizes Spring Card that cover plate under the seat is fixed on the hanger, and afterbody is larger, can clamp seat lower cover plate.
Using the thick rubber pad of 2mm under hanger and the seat between the cover plate, have certain elasticity in addition, prevent that fast lock pin nail is loosening, avoid simultaneously the generation noise that collides with between the cover plate and hanger under the seat.
Unloading process: the hole of opening of using screwdriver to insert the pin afterbody, the rotation screwdriver applies downward power to cover plate under the seat and namely can pull down cover plate under the seat.
