The present invention provides a kind of polycyclic pull explosive screw that can be very good to bear larger longitudinal pulling force and transverse vibration gap at the same time.The polycyclic pull explosive screw bag includes screw and the expansion sleeve being sleeved on outside screw, the axial close-packed arrays of the expansion sleeve along the screw are equipped with multiple, the both ends open of the expansion sleeve is in outwards widened horn-like, the side wall of the expansion sleeve is equipped with some notch vertically, and the notch extends from the opening of the expansion sleeve to the middle part of expansion sleeve.The expansion sleeve of the present invention is equipped with multiple, when expansion sleeve expands, the horn-like opening junction expansion of adjacent expansion sleeve, the expansion tongue piece that can make mutually the to align up and down expansion that intermeshes diverges to, not only it is being longitudinally formed multilayer expansion tongue piece, there is provided bear pulling force, the multiple expansion tongue pieces also diverged to by spatial intersecting in the longitudinal direction of bigger, the bump clearance that the transverse vibration that pull explosive screw is subject to produces is can be very good to bear and reduced, improves the stability of pull explosive screw.
Description
Technical field
The present invention relates to pull explosive screw technical field, and in particular to a kind of polycyclic pull explosive screw.
Background technology
Presently commercially available pull explosive screw is the pull explosive screw of unilateral tongue piece, since the side wall of cylindrical shape expansion sleeve is light
Sliding surface, and the tongue piece stress for providing longitudinal pulling force is single, therefore the pull explosive screw of this structure can only bear less longitudinal direction
Pulling force, in face of needing to bear larger longitudinal pulling force and the usage scenario in horizontal bump clearance, then power has and does not capture.
The content of the invention
It can be very good to bear larger longitudinal pulling force and transverse vibration gap at the same time the purpose of the present invention is to propose to a kind of
Polycyclic pull explosive screw.
The polycyclic pull explosive screw provided according to the present invention, including screw and the expansion sleeve that is sleeved on outside screw, key are
The axial close-packed arrays of the expansion sleeve along the screw are equipped with multiple, and the both ends open of the expansion sleeve is in outwards widened
Horn-like, the side wall of the expansion sleeve is equipped with some notch vertically, and the notch is from the opening of the expansion sleeve to expansion sleeve
Middle part extension.
The polycyclic pull explosive screw of the present invention, application method is identical with existing pull explosive screw, passes through the nut of tightening screw
Expansion sleeve is partly slit open expansion, block wall and complete to fix, unlike existing pull explosive screw, expansion sleeve of the invention
Equipped with multiple, when expansion sleeve expands, the horn-like opening junction expansion of adjacent expansion sleeve, can make what is mutually aligned up and down
The expansion that intermeshes of expansion tongue piece diverges to, and is not only being longitudinally formed multilayer expansion tongue piece, there is provided pulling force is born in the longitudinal direction of bigger, also
The multiple expansion tongue pieces diverged to by spatial intersecting, can be very good to bear and reduce the transverse vibration that pull explosive screw is subject to and produce
Bump clearance, improve the stability of pull explosive screw.
Further, the notch is arranged in pairs using the side wall midpoint of the expansion sleeve as symmetrical centre, so that expansion sleeve
Explosion notch uniform force.
Further, the opening interface point uniform gap of the notch and the expansion sleeve is set, and ensures the swollen of expansion sleeve
The contact position uniform gap of swollen tongue piece and wall, lifts stability.
Further, the notch of two neighboring expansion sleeve is set along the axial mutually staggered positions of the screw.So may be used
So that the expansion tongue piece of neighbouring two expansion sleeves and the contact position of wall stagger vertically, a greater degree of lifting is drawn quick-fried
Bear pulling force in the longitudinal direction of screw.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the structure diagram of the expansion sleeve of the present invention.
Fig. 3 is the radial distribution position view of the notch of the expansion sleeve of the present invention.
Embodiment
Below against attached drawing, by the description to embodiment, for example involved to the embodiment of the present invention is each
Mutual alignment and connection relation, the effect of each several part and operation principle between the shape of component, construction, each several part etc. are made into one
The detailed description of step.
Such as Fig. 1,2,3, polycyclic pull explosive screw of the invention, including screw 1 and the expansion sleeve 2 being sleeved on outside screw 1, expansion
The axial close-packed arrays of set 2 along screw 1 are equipped with multiple, and the both ends open of expansion sleeve 2 is in outside widened horn-like, expansion sleeve
2 side wall is equipped with notch 21 vertically, and notch 21 extends from the opening of expansion sleeve 2 to the middle part of expansion sleeve 2.
The polycyclic pull explosive screw of the present invention, application method is identical with existing pull explosive screw, passes through the nut of tightening screw
Expansion sleeve is partly slit open expansion, block wall and complete to fix, unlike existing pull explosive screw, expansion sleeve of the invention
2 be equipped with it is multiple, expansion sleeve 2 expand when, adjacent expansion sleeve it is horn-like opening junction expansion, can make mutually to align up and down
The expansion that intermeshes of expansion tongue piece diverge to, be not only longitudinally formed multilayer expansion tongue piece, there is provided pulling force is born in the longitudinal direction of bigger,
The multiple expansion tongue pieces also diverged to by spatial intersecting, can be very good to bear and reduce the transverse vibration production that pull explosive screw is subject to
In the raw bump clearance, improve the stability of pull explosive screw.
As preferred embodiment, notch 21 is arranged in pairs using the side wall midpoint of expansion sleeve 2 as symmetrical centre, such as Fig. 2
Shown, notch 21A and notch 21B are set in pairs using the side wall midpoint of expansion sleeve 2 as symmetrical centre, so that the explosion notch of expansion sleeve
Uniform force.
Preferably, notch 21 and the opening interface point uniform gap of expansion sleeve 2 are set, as shown in figure 3, ensureing expansion sleeve 2
Expansion tongue piece and wall contact position uniform gap, lifted stability.
Preferably, the notch of two neighboring expansion sleeve is set along the axial mutually staggered positions of screw 1.It can so make
Under the expansion tongue piece of two neighboring expansion sleeve and the contact position of wall stagger vertically, a greater degree of pull explosive screw that lifted
Bear pulling force in longitudinal direction.
