A kind of interior six point cylindrical head bolt, it is as shown in Figures 1 to 5, tight for being carried out between layer 1 to be fixed and locking layer 2
The outer end face of mating, including cylinder locking head 3 and pin rod 4, cylinder locking head 3 is equipped with interior hexagonal close-fitting hole 5.It is locked by hexagonal
Tool and interior hexagonal close-fitting hole 5 carry out mating rear screw, and pin rod 4 is made to pass through layer 1 to be fixed and locking layer 2, and cylinder locking head 3 is made
Outside for layer 1 to be fixed compresses, and the close-fitting for realizing layer 1 to be fixed between the layer 2 that locks connects.
Specifically, pin rod 4 includes tightening latch 41, screw rod 42 and extends to transition tapering 43 between screw rod 42 by tightening latch 41,
Tightening latch 41 is connected with cylinder locking head 3, and the diameter of tightening latch 41 is greater than the diameter of screw rod 42, the outer surface smoother of tightening latch 41, locking
It is equipped with the wide-mouth support portion 22 to match with transition tapering 43 at the top of the matching hole 21 of layer 2, locks in interior six point cylindrical head bolt
Under state, wide-mouth support portion 22 is abutted against with transition tapering 43, the inner face 31 of cylinder locking head 3 and the through-hole of layer 1 to be fixed
11 top escape groove inner end walls 12 match docking.
The realization function and principle of internal six point cylindrical head bolt are illustrated:
4 grafting of pin rod is carried out first, and screw rod 42 passes through through-hole 11 and enters in matching hole 21,42 spiral of screw rod and matching hole 21
Between realize spiral be spirally connected, be screw-coupled to transition tapering 43 and abut against with wide-mouth support portion 22 as locking, at this time due to transition cone
Abutting relation between portion 43 and wide-mouth support portion 22 limits the axial movement of screw rod 42, prevents screw rod 42 into one
Axial displacement locking is walked, that is, ensures the insert depth of cylinder locking head, layer 1 to be fixed is protected to be not damaged, and transition is bored
The conical design in portion 43 has certain crimping surplus, which is not enough to damage layer 1 to be fixed, and can ensure that cylinder locks again
First 3 lock layer 1 to be fixed.
As shown in Figure 1, the conical surface section in transition tapering 43 is in flat linear structure, and the conical surface 43 and interior hexagonal cylindrical head
The axis of bolt be in the angle α, preferably 45 °.45 ° of conical surface design can ensure certain crimping surplus, and surplus is moderate, there is no
The situation into amount deficiency is bored into or is bored in transition, and the layer to be fixed of the materials such as particularly suitable glassy layer uses, certainly, if for modeling
Material or aluminum products, the range of the conical surface angle can be slightly wide, is maintained between 30 ° ~ 60 °.
In another scheme, the arc-shaped cable architecture in conical surface section in transition tapering 43, it is to be fixed that it is suitable for glass materials
Layer 1 can provide more accurate limit.
Embodiment one,
As shown in figure 3, cylinder locking head 3 and the thickness of the axial dimension and layer 1 to be fixed of tightening latch 41 match.Escape groove
Inner end wall 12 matches with the bottom surface distance of layer 1 to be fixed and the axial dimension of tightening latch 41, supports in transition tapering 43 and wide-mouth
Portion 22 abuts against under state, and the inner face 31 of cylinder locking head 3 is abutted against with escape groove inner end wall 12, realizes that close-fitting connects, nothing is appointed
What mating surplus, it is ensured that the fastening of layer 1 to be fixed is stablized, and the top end face of cylinder locking head 3 is equal with the top surface of layer 1 to be fixed
Together.
Embodiment two,
As shown in figure 4, the inner face 31 of cylinder locking head 3 and the 11 top escape groove inner end wall 12 of through-hole of layer 1 to be fixed
Between be equipped with gap 6, sealing ring 7 is equipped in gap 6.And the gap 6 is slightly less than the thickness of sealing ring 7.
It is coupled, is met non-rigid as the elasticity between cylinder locking head 3 and layer to be fixed 1 by the elasticity of sealing ring 7
Compressing structure, external environment on the one hand can be prevented cold and hot, expanding with heat and contract with cold of generating of bolt is caused to become the pressure of glassy layer 1
Change fragmentation, on the other hand can play waterproof action, prevent external moisture from invading.
Embodiment three,
As shown in figure 5, screw rod 42 is inner screw, the cylindrical wall of inner screw is smooth, and 21 inner wall of matching hole of locking layer 2 is flat
Sliding, cylindrical wall matches with 21 inner wall of matching hole, and the screw hole and outer bolt 10 of inner screw are matched.Cylindrical wall is equipped with and is used for
The mating annular groove 9 of O-ring 8 is coupled.
By the design of inner screw, locking operation can be carried out from internal layer by outer bolt, it is tight to reduce outdoor glass layer
The difficulty matched, it is only necessary to interior six point cylindrical head bolt is dummy across through-hole 11, then locking is carried out from inside.Another party
Face facilitates processing mating annular groove 9 on inner screw, and built-in 0 type circle 8 can play the role of improving leakproofness, has prevented sleet mist
The steam of weather invades.
The outer bolt 10 is preferably dormant bolt, and the inner wall for the layer 2 that locks is smooth, outside the head end for preventing outer bolt 10
Dew, avoids the case where injuring infant generation.
By above description it can be found that a kind of interior six point cylindrical head bolt of the utility model, using setting for the transition conical surface
Meter can control the pressing force that cylinder locking head treats fixing layer while playing locking effect, prevent layer to be fixed from existing
Deformation damage.It is particularly well suited to the fixation of glassy layer, glassy layer is not in locking fragmentation.Using multi-sealing structure, can prevent
The intrusion of sealing vapour, and have certain control of expanding with heat and contract with cold, further protect glassy layer.Using the design of inner screw, lead to
It crosses outer bolt and realizes two-way locking, close-fitting operation is convenient, and fixation is more reliable.Outer bolt is also dormant bolt, prevents outside
The bolt head of bolt is exposed, reduces security risk.
The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model
Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model
