Abstract
The utility model is related to a kind of packing ring, more particularly to a kind of metal resistance to compression packing ring.Described packing ring appearance profile is Long Circle, and its two ends is semicircular structure, and centre is rectangle, and gasket hole is concentric with one of semicircular structure.The special shape of this metal compressive pads circle provides multiple contact positions for slotted hole, neither influence the installation of lock, bolt connection piece is solved again because rounded washers pressure-bearing makes packing ring deform, causes nut effectively to tighten, influence the problem of the load characteristic of bolt connection piece.
Description
Technical field
The utility model is related to a kind of packing ring, and more particularly to a kind of metal resistance to compression packing ring and lock and the connection of curb girder joint are tied
Structure.
Background technology
Military, civil transport goods bridge gate is locked in the lock 2 on big opening curb girder joint 1 after closing with latch hook thereon
On, lock 2 is bolted part and links together with curb girder joint 1, and traditional bolt connection piece is by bolt 5, nut 4 and circle
Packing ring 3 is constituted, and sees Fig. 1.To ensure the fit clearance at goods bridge gate and big opening both sides, adjustment lock is needed when lock 2 is installed
2 positions of seat, the upper bolt hole of lock 2 uses slotted hole.When tightening nut 4, because circular washer 3 is small with the contact area of lock 2, cause
Circular washer 3 deforms, and influences the load characteristic of bolt connection piece.
The content of the invention
The purpose of this utility model：A kind of metal resistance to compression packing ring and lock and curb girder joint suitable for slotted hole is provided to connect
Binding structure.
The technical solution of the utility model：A kind of metal resistance to compression packing ring, it is characterized by：Described packing ring appearance profile is length
Circle, its two ends are semicircular structures, and centre is rectangle, and gasket hole is concentric with one of semicircular structure.
Further, described packing ring is made of 30CrMnSiA steel.
A kind of lock and curb girder joint connecting structure, described structure include lock, curb girder joint and fastening lock
Bolt connection piece, it is characterized by：Curb girder joint upper bolt hole is circle, and lock upper bolt hole is Long Circle, is set with bolt
Metal resistance to compression packing ring, described metal resistance to compression packing ring appearance profile is Long Circle, and its two ends is semicircular structure, and centre is square
Shape, gasket hole is concentric with one of semicircular structure.
Further, the semicircle centre-to-centre spacing of metal resistance to compression packing ring is semicircular more than or equal to Long Circle bolt hole on lock
Centre-to-centre spacing.
The beneficial effects of the utility model：The special shape of this metal compressive pads circle provides multiple contact for slotted hole
Position, neither influences the installation of lock, and bolt connection piece is solved again because rounded washers pressure-bearing makes packing ring deform, and causes
Nut can not be tightened effectively, influence the problem of the load characteristic of bolt connection piece.

Fig. 3 is the schematic diagram of the attachment structure of a kind of lock of the utility model and curb girder joint.
In figure：1 is curb girder joint, and 2 is lock, and 3 is circular washer, and 4 is nut, and 5 is bolt, and 6 is metal resistance to compression packing ring.
Specific embodiment
The present invention is a kind of metal resistance to compression packing ring.Described packing ring appearance profile is Long Circle, and its two ends is semicircle knot
Structure, centre is rectangular configuration, and the width of rectangular configuration is consistent with the diameter of semicircular structure, and gasket hole is semicircle with one of
Structure is concentric.Packing ring is made of 30CrMnSiA steel, is molded by special mould punching.Packing ring is used for a kind of lock 2 and curb girder
The attachment structure of joint 1, the attachment structure includes the bolt connection piece of lock 2, curb girder joint 1 and fastening lock 2, its feature
For：The upper bolt hole of curb girder joint 1 is circle, and the upper bolt hole of lock 2 is Long Circle, and the head of bolt 5 is in the side of curb girder joint 1, spiral shell
Equipped with the nut 4 of fastening lock 2 on bolt 5, metal resistance to compression packing ring 6 is set between the top nut 4 of bolt 5 and lock 2.
The semicircle centre-to-centre spacing of metal resistance to compression packing ring 6 is more than or equal to the semicircular center of Long Circle bolt hole on lock 2
Away from.Before nut 4 is tightened, metal resistance to compression packing ring 6 can rotate 180 ° and adjust its position around the axis of bolt 5, and have no effect on lock 2
The adjustment of position；When bolt 5 is on the lower side relative to the slotted hole of lock 2, described its gasket hole of packing ring is positioned at its lower part；Work as spiral shell
When bolt 5 is on the upper side relative to the slotted hole of lock 2, described its gasket hole of packing ring is positioned at packing ring top.When the position adjustment of lock 2 terminates
Afterwards, the position of metal resistance to compression packing ring 6 is well placed, it is fitted with lock 2 completely, then nut 4 is tightened on request.Nut 4 is pressed
It is required that after tightening, described packing ring and the fitting part pressure-bearing of lock 2, with good compressive property, it is ensured that bolt connection piece
Load characteristic.
