Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated.
According to above-mentioned technical proposal, a kind of sleeve pipe fastener, including the first tubing 1, locking are proposed in the present embodiment
Device 2, holding screw 3, the holding tubing 5 of screw 4 and second, wherein：Locking device 2 includes holding block 21, jacking block 22 and voussoir tightly
23.Wherein, hold block 21 tightly to be enclosed on the first tubing 1, the side for holding block 21 tightly is provided with opening, is open tight by holding screw 4 tightly
Gu.The side for holding block 21 tightly sets fluted, and jacking block 22 is arranged in groove, and the side of groove is provided with the first inclined-plane, jacking block
22 sides are provided with the second inclined-plane, and two sides of voussoir 23 coordinate with the first inclined-plane and the second inclined-plane, set on jacking block 22 respectively
Have and holding screw 3 is provided with mounting hole, mounting hole.
Second tubing 5 is set in outside locking device 2, and the second tubing 5 is provided with and the mounting hole of jacking block 22 corresponding first
Through hole.The external diameter of first tubing 1 is less than the internal diameter for holding block 21 tightly.The external diameter for holding block 21 tightly is less than the internal diameter of the second tubing 5.Second
The second through hole is provided with tubing 5, the second through hole is correspondingly arranged with holding screw 4 tightly.It is convenient to be revolved from outside to holding screw 4 tightly
Turn.
Wherein, holding screw 4 and holding screw 3 are provided with spring shim.Because the utility model uses the fixation side of swelling
Formula, is difficult to prevent from loosening only by tightening screw to be so requiring very high with holding the anti-loosening property of screw 4 tightly to holding screw 3,
Need to add and the supporting spring shim of screw, to improve fastening effect.
One end of first tubing 1 is provided with installation end, and the diameter of installation end is less than the first tubing 1, holds block 21 tightly and is enclosed on peace
Fill on end.Now can be uncorrelated to the internal diameter for holding block tightly by the diameter of the first tubing, it is more convenient the size of control sleeve pipe.
The face that the inclined-plane of voussoir 23 and first and the second inclined-plane coordinate is plane, and the outside of voussoir 23 is cambered surface.Using this
The motion of voussoir is conveniently realized in design, and locking is more convenient.The outside of jacking block 22 is cambered surface.It is engaged with the inside of the second tubing.
Jacking block 22 with groove cooperate.It is preferred that, groove is rectangular recess.The direction of motion of convenient limitation jacking block.
The utility model make use of the principle that voussoir is locked, and can realize that larger swelling is imitated by less pretightning force
Really, trip bolt is difficult to loosen, so fastening effect is relatively good, big tubule is difficult loose or dislocation, and locking shock resistance is stronger.Together
When dismounting it is simple, holding and the swelling of the second pipe of the first pipe can be just realized by screw.Each part of the utility model is to essence
The requirement of degree is relatively low, reduces production cost, and can change the cross sectional shape and size of part, for being applicable different building rings
Border.
The utility model occupies little space compared to prior art, is applicable to smaller space.First pipe in the present embodiment
The tubing 5 of material 1 and second is circle, but during actual production, locking device 2 can change cross sectional shape, is included but is not limited to
Circular, square, polygon or other shaped faces.
The utility model is applied to a variety of occasions, therefore number and size species of the holding screw 3 with holding screw 4 tightly
Also it can change therewith.Because the utility model uses the fixed form of swelling, so to holding screw 3 with holding screw 4 tightly
Anti-loosening property require it is very high, only by tighten screw be difficult prevent loosen, it is necessary to the pad supporting with screw be added, to carry
High fastening effect.Because machining surface can not possibly be perfect, scrambling can be filled up using pad, if with conventional pads,
Being easily deformed after long-time use causes pad to play a part of making up the difference, therefore pad selected in the present embodiment is spring
Spring in pad, spring shim can play a part of making up the difference automatically according to automatic telescopic the need for use environment, make machinery even
Connect relation even closer.
It is of the present utility model to install as follows with operation principle：The holding block 21 is socketed on the first tubing 1, is embraced when screwing
During tight screw 4, holding block 21 tightly can hold tightly on the outer surface of the first tubing 1, realize that the holding for holding the tubing 1 of block 21 and first tightly is moved
Make；Then jacking block 22 is placed in the groove for holding block 21 tightly, two voussoirs 23 are placed on jacking block 22 to be formed with holding block 21 tightly
Indentation, there, the second tubing, 5 sets are connected on locking device 2, and holding screw 3 passes through precession in the hole opened on the second tubing 5
In jacking block 22；With screwing for holding screw 4, jacking block 22 is ejected, and 22 two inclined-planes of jacking block can be in contact with voussoir 23, by
In the constraint for having the inclined-plane for holding block 21 tightly, voussoir 23 can be moved along the inclined-plane for holding block 21 tightly, and outside distending always holds out against the second pipe
The inwall of material 5, realizes that swelling is acted.Because jacking block 22 is not contacted directly with the second tubing 5, and inclined-plane is being understood suffered by the external world
Vibration and suffered power decomposed along inclined-plane, be delivered to power on holding screw 3 and reduce, such holding screw 3 is vibrating
Or for a long time by be difficult in the state of variable force loosen.Conversely speaking, holding screw 3 only need to the pretightning force of very little just can swelling
The inwall of second tubing 5；Jacking block 22, voussoir 23, the interaction on the inclined-plane of holding block 21, are put the power for being delivered to voussoir 23
Greatly, and the inwall of the second tubing 5 is acted on, preferable swelling effect can be reached, shock-proof check ability is stronger.
It should be understood that these embodiments are merely to illustrate the utility model rather than limit scope of the present utility model, readding
Read after the utility model, modification of the those skilled in the art to the various equivalent form of values of the present utility model falls within the application
Appended claims limited range.
