Description
Technical field
The utility model belongs to technical field of fastening, and in particular to a kind of spring locking pin.
Background technology
Locking pin is a kind of by axial fast between rotary screw head or handle realization module and module, module and platform
Straight pin speed locking or unclamped.Main constituent element：Locking body, check lock lever, steel ball, different structure form also have other differences
Element.5 concentric steel balls are housed in locking pin body.When loosening locking pin screw thread, steel ball can automatically inside retraction locking body,
At this moment, locking pin can be inserted into or extract out by the circular hole of lock workpiece.Locking pin insertion is gradually twisted after lock workpiece hole with hand when use
Tight locking pin head part, while steel ball gradually protrudes, locking pin automatic centering and clamp module.
In some special equipments, it is desirable to provide the locking pin of certain coupling mechanism force, when the pulling force between locking member is less than
When coupling mechanism force, component is locked；When pulling force is more than coupling mechanism force, component is released.But existing locking pin can only provide letter
Single locking function, no matter how external pull must all unclamp locking member manually, cannot need to provide according to actual conditions
Specific coupling mechanism force.
Utility model content
Simple locking function can only be provided for above-mentioned existing locking pin, no matter how all necessary manual external pull is
Locking member is unclamped, the defect for providing specific coupling mechanism force, the utility model cannot be needed to provide a kind of bullet according to actual conditions
Spring locking pin, its object is to：Different size of coupling mechanism force can be provided as needed, realized when the pulling force between locking member
When less than coupling mechanism force, component is locked；When pulling force is more than coupling mechanism force, component is released.
The technical solution adopted in the utility model is as follows：
A kind of spring locking pin, including locking body, check lock lever and steel ball, check lock lever and steel ball are arranged inside locking body,
Be additionally provided with wedge-shaped axis and spring between check lock lever and steel ball, both ends of the spring respectively with check lock lever and wedge-shaped axis connection.
After the technical solution, position of the check lock lever in locking body can be adjusted to change check lock lever and wedge-shaped axis
Between spring compression degree.Spring-compressed degree is different, causes the pressure between wedge-shaped axis and steel ball different.When outside application
When portion's strength is less than the pressure between wedge-shaped axis and steel ball, steel ball can not be pushed back inside locking body, execute lock function at this time；
When more than pressure between wedge-shaped axis and steel ball, steel ball can be pushed back inside, realize unlock.It, can be with according to above-mentioned principle
By shirtsleeve operation, position of the check lock lever in locking body is adjusted to provide the coupling mechanism force of a particular value.
Preferably, steel ball has multiple, and the top of the wedge shape axis has multiple inclined-planes, each inclined-plane connects with a steel ball
It touches.The purpose of the preferred embodiment is the pressure converted the pressure of spring longitudinal direction to steel ball transverse direction.
Preferably, it is connected through a screw thread between locking body and check lock lever.It can adjust check lock lever by way of turning and exist
Position in locking body.
Preferably, locking body inner wall is provided with multiple buckles I along its length, and in other words each buckle I is located at locking
The depth of internal not phase, there are one buckle II, the buckles I to cooperate with buckling II for the check lock lever side.It can pass through
The buckle I that buckle II is buckled into different location realizes the purpose of position of the adjustment check lock lever in locking body.
Preferably, the end of check lock lever is provided with handle.Setting handle can conveniently adjust check lock lever inside locking body
Position.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1. position of the check lock lever in locking body can be adjusted to provide the lock of a particular value by shirtsleeve operation
Clamp force.When the pulling force between locking member is less than coupling mechanism force, component is locked；When pulling force is more than coupling mechanism force, component is loose
It opens.This specific function can be used for some special equipments with this demand.
2. in the prior art, locking pin can only by manual locking or release, no matter external pull have it is much all not can from
It is dynamic to unclamp, in this way when occur it is unexpected cause it is external there is very big pulling force when, may cause locking pin that can not unlock to stuck or
Damage equipment.And the utility model can set the coupling mechanism force of a safety so that the coupling mechanism force is much larger than normal running conditions
Under external pull, to maintain the normal operation of equipment.And ought surprisingly occur, excessive external pull is more than safety lock clamp force
When, locking pin can unclamp automatically, prevent equipment stuck or damage.
3. the inclined-plane on the top by wedge-shaped axis converts the pressure of spring longitudinal direction to the pressure to steel ball transverse direction.
4. can be threaded or buckle, it can adjust check lock lever by way of turning or changing and snap connection position and exist
Position in locking body.
5. handle, which is arranged, can conveniently adjust position of the check lock lever inside locking body.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is the structural schematic diagram of the utility model.
