Description
Technical field
The utility model is related to manual hardware tool technical field, specifically a kind of band unlock pin nut setter.
Background technology
Our nut setter is all matching used with box spanner at present, and the square tenon of box spanner can be inserted into sleeve
The two is not allowed to disengage in square hole, in the course of work, current general structure is to be equipped with hole, hole in the square tenon of box spanner
It is interior that spring and round steel pearl (as shown in Figure 8) are housed, Zhu Gou (as shown in Figure 6) is equipped on four sides in the square hole of sleeve,
When square tenon insertion sleeve square hole, steel ball can enter Zhu Gou under spring promotion, prevent square tenon from being disengaged with sleeve with this.This knot
Structure is suitable for small sleeve, if sleeve is larger heavier, the effect of round steel pearl stress will be easy to skid off from Zhu Gouzhong, cause to cover
Cylinder is detached with box spanner, insecurity occurs.
In order to overcome this defect, occur replacing round steel pearl equipped with straight pin in the square tenon of box spanner currently on the market
Structure (as shown in Figure 9), the Zhu Gou of sleeve square hole medial surface also cancels, and is changed to borehole structure (as shown in Figure 7), during work
Square tenon upper cylindrical pin can be inserted into the hole of sleeve square hole side, this structure can ensure that will not when sleeve is used with box spanner
It disengages, but also be difficult to both separation, straight pin in square tenon need to be enable with special tool from sleeve square hole side
Deviate from hole, realize that square tenon is detached with sleeve, use very troublesome.
By retrieval, do not find that the sleeve for the technical issues of the utility model can solve can be solved.
Utility model content
The purpose of this utility model is to provide a kind of bands to unlock pin nut setter, sleeve can be made to be combined with box spanner
Closely, it is safe to use, and can realize the two Quick release separation.Seal location is located on the inside of stepped hole, and outside be can't see, is not easy
Damage, it is highly practical.Specialist tools are not needed to, it is easy to use.
In order to achieve the above objectives, the utility model employs following technical solution, and a kind of band unlocks pin nut setter,
Including sleeve body, unlock pin, the unlock pin is installed in the Radial Solutions lockhole that sleeve body opens up, and the solution lockhole is ladder
Hole, the unlock pin is stepped for three sections, respectively epimere, interlude, hypomere, and wherein interlude diameter is less than hypomere diameter,
Hypomere diameter is less than epimere diameter；The stepped hole is divided into outside macropore and inside aperture, and wherein macropore bottom is in the rounding conical surface,
The epimere of the unlock pin is located in macropore, and interlude and hypomere are respectively positioned in aperture；The hardness of the unlock pin is more than sleeve
Body hardness.
After the unlock pin is inserted into stepped hole, external force is applied to the external large end face of the epimere of unlock pin, the inside of epimere
The macropore bottom that end face forces in contact is in the rounding conical surface, is deformed after the stress of rounding conical surface top so that on the aperture of stepped hole
Port diameter becomes smaller, i.e., described aperture upper port diameter is less than the epimere diameter of unlock pin, while is less than hypomere diameter, but aperture
Upper port diameter is more than the interlude diameter of unlock pin.
The sleeve body Single port is socket end, and the other end is cubic nose end, wherein the inlet setting at four square opening ends is led
To slot.
The guide groove is arc.
The outer end face of the epimere of the unlock pin and sleeve outer wall flush, the inner face and set of the hypomere of the unlock pin
The square hole inner wall flush of cylinder.
The utility model has the advantages that compared with prior art：
One side of four square end of sleeve body is equipped with stepped hole, and stepped hole macropore bottom is in inverted cone-shaped；Simultaneously four
Square end and the front end of hole same side are equipped with guide groove.Unlock pin is stepped, and mid diameter is less than both ends diameter.In order to make
Unlock pin is fixed in sleeve body opening, it is desirable that the hardness of unlock pin is more than sleeve body hardness after heat treatment, and unlock pin is inserted into ladder
Kong Hou, fixing sleeve cylinder, external force are applied to the large end face of unlock pin, and the stepped hole that the opposite side of large end face forces in contact again falls
Circular conical surface, rounding conical surface top intensity is relatively low, is deformed after stress so that the aperture portion upper diameter of stepped hole becomes smaller, and is less than
The both sides step diameter of unlock pin, but more than the middle section diameter of unlock pin, such unlock pin is just stuck in stepped hole, no
It can deviate from, and have certain motion range in hole.The characteristics of the utility model is exactly that seal location is located on the inside of stepped hole,
Outside can't see, and be hardly damaged, highly practical.Specialist tools are not needed to, it is easy to use.

Specific embodiment
Detailed description and technology contents in relation to the utility model, cooperation description of the drawings is as follows, however attached drawing is only to refer to
With purposes of discussion, not it is used for limiting the utility model.
According to Fig. 1 to Fig. 5, a kind of band unlocks pin nut setter, including sleeve body 4, unlock pin 5, the unlock pin peace
In the Radial Solutions lockhole opened up loaded on sleeve body, the solution lockhole is stepped hole 41, and the unlock pin is stepped for three sections, respectively
For epimere, interlude, hypomere, wherein interlude diameter is less than hypomere diameter, and hypomere diameter is less than epimere diameter；The stepped hole
Be divided into outside macropore and inside aperture, macropore bottom is in the rounding conical surface, and the epimere of the unlock pin is located in macropore, interlude with
Hypomere is respectively positioned in aperture；The hardness of the unlock pin is more than sleeve body hardness.
After the unlock pin is inserted into stepped hole, external force is applied to the external large end face of the epimere of unlock pin, the inside of epimere
The macropore bottom that end face forces in contact is in the rounding conical surface, is deformed after the stress of rounding conical surface top so that on the aperture of stepped hole
Port diameter becomes smaller, i.e., described aperture upper port diameter is less than the epimere diameter of unlock pin, while is less than hypomere diameter, but aperture
Upper port diameter is more than the interlude diameter of unlock pin.
The sleeve body Single port is socket end, and the other end is cubic nose end, wherein the inlet setting at four square opening ends is led
To slot 42.The guide groove is arc.
The outer end face of the epimere of the unlock pin and sleeve outer wall flush, the inner face and set of the hypomere of the unlock pin
The inner radial wall flush of the square hole of cylinder.
When sleeve and box spanner are used cooperatively, before straight pin 2 in box spanner square tenon 1 is along sleeve body square hole
The guide groove 42 at end enters in sleeve square hole, when moving to 41 position of stepped hole, in 3 thrust lower cylindrical pin of spring, 2 access aperture
It is interior, while jack up unlock pin 5.The secure connection of sleeve and box spanner is realized, can be used safely.When needing sleeve and sleeve
When spanner detaches, unlock pin 5 is pressed, the straight pin 2 in square tenon will be released stepped hole by unlock pin 5, so as to realize square tenon 1
With the separation of sleeve.
The characteristics of the utility model is exactly that seal location is located on the inside of stepped hole, is not fallen out, and have centainly in hole
Motion range.Outside can't see, and be hardly damaged, highly practical.Specialist tools are not needed to, it is easy to use.
The above is only the preferred embodiment of the present invention, non-to limit the scope of the claims of the utility model,
He uses the equivalence changes of the utility model patent spirit, should all belong to the scope of the claims of the utility model.
