Description
Technical field
The utility model is related to a kind of hexagon slotted nuts based on axis pin limiting.
Background technology
Nut in automobile manufacture industry is subjected to the torque active force of high intensity, and plain nut is tied with connector without positioning
Structure does not have the fixed locking mechanism of positioning, easily loosens after threaded connection and even come off, influence vehicle safety after connection fastening
Energy；Conventional nut prevents nut loosening, anti-loosening effect by increasing spring washer to increase between nut and bolt frictional force
Fruit is bad；201220360414.1 patented technology of Patent No. sets one on an end face of nut body in the prior art
Open slot is symmetrical arranged two locking through-holes perpendicular to open slot at open slot, and locking through-hole is passed through by spiral shell by stove bolt
Maternal body is locked on bolt, small perpendicular to the through-hole operating space of open slot, and stove bolt connection is inconvenient, and installation operation is numerous
It is trivial, the high intensity connection request of automobile connection structure can not be adapted to, as running car vibrates, stove bolt is easier to loosen de-
It falls, connection is unreliable, to bonding strength without significantly improving.
Invention content
Technical problem to be solved in the utility model, which is to provide one kind, has anti-loose structure, and installation operation is convenient, even
Connect the hexagon slotted nut reliably limited based on axis pin.
The hexagon slotted nut based on axis pin limiting of the utility model, including hex nut main body, it is characterised in that：Six
Recessed parallel with hex nut main body end face of hex nut main center, trend is provided through on the end face of angle nut main body one end
Slot is inserted into alignment pin in groove；Groove-width dimension is adapted with alignment pin diameter, and groove depth dimensions are slightly less than
Alignment pin diameter；With being provided through bolt-center in the bolt body of hex nut main body cooperation, perpendicular to bolt-center
The through-hole of line；
A plurality of groove is provided on the hex nut main body end face；
The a plurality of groove intersects through hex nut main center；
3 are provided on the hex nut main body end face to intersect through the groove of hex nut main center；
The hex nut material of main part is one of 45# or 35#；
The hex nut main body specification is M8~M22；Groove-width dimension is 3.1~6.7mm, depth dimensions for 3~
8mm。
The hexagon slotted nut based on axis pin limiting of the utility model, hex nut main body are connected with bolt and fasten
Afterwards, alignment pin is inserted into the groove on hex nut main body end face, and passes through respective through hole positioning and locking in bolt body, vehicle
Vibration will not loosen for a long time in driving process, and connection is reliable；Hex nut main body sets a plurality of intersect to pass through on end face
Wear the groove at nut center, the through-hole direction in bolt body can arbitrarily select, can be with after the connection fastening of hex nut main body
The groove of through-hole in a plurality of groove alignment bolt body is selected to be inserted into alignment pin, nut is non-directional with being bolted, installation
Attended operation is convenient, and connection is reliable.
Description of the drawings
Fig. 1 is the hexagon slotted nut planar structure schematic diagram that the utility model embodiment is limited based on axis pin；
The right side that Fig. 2 is Fig. 1 regards schematic diagram.
Specific embodiment
As shown in the figure, a kind of hexagon slotted nut based on axis pin limiting, including hex nut main body 1, hex nut master
1 center of hex nut main body, the trend groove 2 parallel with 1 end face of hex nut main body are provided through on 1 one end end face of body,
Alignment pin is inserted into groove 2；2 width dimensions of groove are adapted with alignment pin diameter, and 2 depth dimensions of groove are slightly less than
Alignment pin diameter；Bolt-center is provided through in the bolt body coordinated with hex nut main body 1, perpendicular to bolt-center
The through-hole of line；Hex nut main body 1 is connected with bolt after fastening, and alignment pin is inserted into recessed on hex nut main body end face
Slot 2, and respective through hole positioning and locking in bolt body is passed through, vibration will not loosen for a long time in vehicle travel process, connect
Reliably.
Further, it is provided with a plurality of groove on hex nut main body end face；A plurality of groove intersects through hexagonal spiral shell
Female main center；Through-hole direction in bolt body can arbitrarily select, and after the connection fastening of hex nut main body, can select more
The groove of through-hole is inserted into alignment pin in groove alignment bolt body, and nut is non-directional with being bolted, and installation connection is grasped
Facilitate, connection is reliable.
Specifically, 3 are provided on hex nut main body end face in the present embodiment to intersect through hex nut main body
The groove at center；3 grooves are uniformly arranged in a circumferential direction.
One of hex nut main body 1 material selection 45# or 35#, process for machining and manufacturing are convenient.
The hexagon slotted nut based on axis pin limiting of the utility model, 1 specification of hex nut main body are M8~M22；It is recessed
2 width dimensions of slot are 3.1~6.7mm, and depth dimensions are 3~8mm.
Table specific as follows：
The hexagon slotted nut based on axis pin limiting of the utility model, hex nut main body are connected with bolt and fasten
Afterwards, alignment pin is inserted into the groove on hex nut main body end face, and passes through respective through hole positioning and locking in bolt body, vehicle
Vibration will not loosen for a long time in driving process, and connection is reliable；Hex nut main body sets a plurality of intersect to pass through on end face
