Abstract
The utility model discloses an anti-looseness device for an outer hexagon bolt or nut. According to the utility model, lock washers are made of elastic materials; the inner hole of the device is a hexagon matched with outer hexagon heads of the bolt or the nut, so that relative rotation can not happen between the bolt or the nut and the lock washers; external taps with certain degrees are arranged on the outer edges of the lock washers; the outer taps are clamped in different clamping grooves of limit sleeves; two clamping grooves are formed in each limit sleeve, one clamping groove conducts axial limiting on the lock washers through the clamped external taps of the lock washers, and the other clamping groove conducts rotating limiting in the axial direction on the lock washers through the clamped external taps of the lock washers; pin shafts are inserted into positioning holes of workpieces and the limit sleeves; when the bolt or the nut is disassembled, the external taps of the lock washers are pried out from the axial limiting clamping grooves of the limit sleeves, the lock washers are taken, and the bolt or the nut can be disassembled normally. The anti-looseness device for the outer hexagon bolt or nut has a well effect of disassembly and looseness prevention.
Description
Affiliated technical field
The utility model relates to a kind of novel locking device, and the machinery that is mainly used in outer-hexagonal hook bolt or nut is locking, specifically a kind of outer-hexagonal hook bolt or nut anti-looseness device.
Background technique
At present, the locking of outer-hexagonal hook bolt or nut is mainly that dependence increases the frictional force between bolt or nut or the frictional force increased between bolt or nut and workpiece reaches locking purpose, the occasion that this locking mode is vibrated in many intense impact still can produce loosening, is not very reliable.In addition, although now widely used lock washer is locking reliable, application area is restricted.
Summary of the invention
For the not only locking reliable but also function for convenience detach of the connection that realizes outer-hexagonal hook bolt or nut, the utility model provides a kind of brand-new mechanical locking device.
The utility model solves the scheme that its technical problem adopts: lock washer is made by elastic material, and its endoporus, for the Hexagon that the outer-hexagonal head with bolt or nut adapts, makes bolt or nut and lock washer not to relatively rotate.The outer rim of lock washer has a plurality of outer tongues at an angle.Outer tongue snaps in respectively in the different draw-in grooves of stop collar.Stop collar is processed with two draw-in grooves, and draw-in groove carries out axial limiting by the outer tongue of the lock washer that snaps in to lock washer, and another draw-in groove carries out around axial rotary stopper lock washer by the outer tongue of the lock washer that snaps in.Bearing pin inserts in the positioning hole of workpiece and stop collar.During dismounting, the outer tongue of lock washer is prized from the axial limiting draw-in groove of stop collar, can dismantle normally bolt or nut after taking off lock washer.Thereby obtain a kind of outer-hexagonal hook bolt or nut anti-looseness device, obtained dismounting and locking the two good result of taking into account.
The beneficial effects of the utility model are, adopt this novel mechanical locking device, have both reached purpose for convenience detach, recycling, have played again good anti-loosing effect.
The accompanying drawing explanation:
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is overall structure schematic diagram of the present utility model.
The A that Fig. 2 is Fig. 1 is to view.
1. bearing pins in figure, 2. stop collar, 3. lock washer, 4. nut, 5. workpiece, 6. bolt, 7. workpiece.
Embodiment
In Fig. 1, Fig. 2, lock washer 3 is made by elastic material, and its endoporus is the Hexagon that the outer-hexagonal head with bolt 6 or nut 4 adapts, and makes bolt 6 or nut 4 can not relatively rotate with lock washer 3.The outer rim of lock washer 3 has a plurality of outer tongues at an angle.Outer tongue snaps in respectively in the different draw-in grooves of stop collar 2.Stop collar 2 is processed with two draw-in grooves, and the outer tongue of the part of lock washer 3 snaps in a draw-in groove, and the elasticity due to the material of lock washer 3, make its outer tongue be close to this draw-in groove, thereby lock washer 3 can not axially be deviate from from stop collar 2 is interior.Certain other outer tongue of lock washer 3, due to the elasticity of material, snaps in another draw-in groove of stop collar 2, makes between lock washer 3 and bolt 6, nut 4, stop collar 2 and can not relatively rotate.Bearing pin 1 inserts in the positioning hole of workpiece 5, workpiece 7 and stop collar 2, existence due to outer-hexagonal head or the nut 4 of bolt 6, make bearing pin 1 not deviate from from positioning hole, simultaneously, make between workpiece 5, workpiece 7, bolt 6, nut 4, stop collar 2, lock washer more than 3 persons and can not relatively rotate, thereby reach the locking purpose of machinery of bolt 6 or nut 4.During dismounting, the outer tongue of lock washer 3 is prized from the axial limiting draw-in groove of stop collar 2, just can dismantle normally bolt 6 or nut 4 after lock washer 3 is taken out from stop collar 2, and can reuse.
Claims (3)
1. an outer-hexagonal hook bolt or nut anti-looseness device is characterized in that: by lock washer, and stop collar, bearing pin forms, lock washer is enclosed within on the outer-hexagonal head or hex-head nut of bolt, and its outer tongue snaps in respectively in two draw-in grooves of stop collar, and bearing pin inserts in the positioning hole of workpiece and stop collar.
2. a kind of outer-hexagonal hook bolt according to claim 1 or nut anti-looseness device is characterized in that: the Hexagon that the endoporus of lock washer adapts for the outer-hexagonal head with bolt or nut, and can be enclosed within on the outer-hexagonal head of bolt or nut; The lock washer outer rim has a plurality of outer tongues, at an angle and have a rebound elasticity.
3. a kind of outer-hexagonal hook bolt according to claim 1 or nut anti-looseness device, it is characterized in that: stop collar is processed with two restraining grooves and a positioning hole, and stop collar is through between bolt or nut and workpiece; Restraining groove can snap in the outer tongue of elasticity of lock washer; Bearing pin can pass positioning hole.
