Description
[technical field]
This utility model relates to the novel single-side bolt fastener of a kind of easy accessibility, belongs to civil construction project, machinery
Mounting technology field.
[background technology]
For the plain bolt being made up of screw rod and nut commonly used at present, when carrying out terminal operation, need to be
Screw rod binding nut are inserted in side, are then tightened by nut at opposite side instrument, and installation requirement installation personnel is simultaneously at structure
The operation of part both sides.But relative to the installation of opening section component more typically, for such as closed cross-section member and inconvenience
For touching the component of wherein one side, this bolt commonly used is using and inconvenient.As concrete filled steel tube,
Beam-column connection etc., owing to column section mostly is closed section, plain bolt can not operate on both sides, therefore common side
Method cannot be installed.The common one-way bolt that expands is because being difficult to the applying of bolt pretightening, and fastening effect is also unable to reach bigger
Requirement is designed under load.And the reserved required precision of punching bolt-for-bolt hole of the prior art is the highest, in-site installation
Difficulty is big, and is difficult to apply at side column and corner post node.And in existing monolateral bolt, it is not suitable for large span or big load
Structure, and need more complicated installation tool and cumbersome installation steps.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes the novel single-side spiral shell of a kind of easy accessibility
Bolt securing member, it is possible to realize monolateral enforcement terminal operation, also can conveniently remove and install as required, reusable.
For achieving the above object, the utility model proposes the novel single-side bolt fastener of a kind of easy accessibility, including
If snap bolt, ring set, some elastomers, some baffle elements, clamping sleeve, fastener, some bodies of rod, some slots and dry rubber substance
Set, the body of rod of described snap bolt is arranged with threaded fastener, slidably clamping sleeve and can the most successively
The ring set slided, together with described fastener is rotatably connected with clamping sleeve, the front end of described ring set is provided with the body of rod, described compression
The rear end of set is provided with and body of rod slot one to one, is equipped with rubber sleeve in described slot, and the described body of rod is inserted in rubber sleeve,
The internal diameter of described rubber sleeve is slightly smaller than the diameter of the body of rod, and the periphery of described ring set is evenly distributed with elastomer, described elasticity
Body is provided with baffle element, and described baffle element is arcuate shape with the connection end of elastomer.
As preferably, the front end of the described body of rod is arcuate shape.
As preferably, the diameter of described clamping sleeve and the equal diameters of installing hole.
As preferably, the front end of the body of rod of described snap bolt is provided with square toes.
The beneficial effects of the utility model: the body of rod in use, is inserted rubber sleeve by this utility model, insertion depth is for protecting
Gap between card clamping sleeve and baffle element is available for baffle element generation change in location, then unilateral bolt fastener is inserted
Installing hole, until baffle element passes fully through the rear end of installing hole, now, elastomer recovers normal condition and carries out baffle element propping up
Support, then fixes snap bolt and drives fastener to rotate by screwing tool, until baffle element is compressed by clamping sleeve, take away and turn
Instrument, then on the body of rod of snap bolt, rotation set is fixed nut and tightens, during insertion, due to the deformation of elastomer so that stop
Body generation change in location, it is impossible to stop, owing to there is frictional force between rubber sleeve and the body of rod, ring set will not travel forward,
During dismounting, lay down fixing nut, fixing fastener, and slewing circle hook bolt, make snap bolt move in installing hole, until circle
Gap between round end and the baffle element of hook bolt is available for baffle element generation change in location, then pulls out the fastening of monolateral bolt
Part, owing to there is frictional force between rubber sleeve and the body of rod during pull-out, ring set will not rearward movement, compared with prior art, it is possible to
Realize monolateral enforcement terminal operation, also can conveniently remove and install as required, reusable.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.

[detailed description of the invention]
Refering to Fig. 1,2, the novel single-side bolt fastener of a kind of easy accessibility of this utility model, including snap bolt 1, ring
Set 2, some elastomers 3, some baffle elements 4, clamping sleeve 5, fastener 6, some bodies of rod 7, some slots 11 and some rubber sleeves
12, the body of rod of described snap bolt 1 is arranged with threaded fastener 6, slidably clamping sleeve 5 and the most successively
Slidably ring set 2, together with described fastener 6 is rotatably connected with clamping sleeve 5, the front end of described ring set 2 is provided with the body of rod 7,
The rear end of described clamping sleeve 5 is provided with and the body of rod 7 slot 11 one to one, is equipped with rubber sleeve 12 in described slot 11, described
The body of rod 7 is inserted in rubber sleeve 12, and the internal diameter of described rubber sleeve 12 is slightly smaller than the diameter of the body of rod 7, on the periphery of described ring set 2 all
The even elastomer 3 that is distributed, described elastomer 3 is provided with baffle element 4, and described baffle element 4 is arc shape with the connection end of elastomer 3
Shape, the front end of the described body of rod 7 is arcuate shape, the diameter of described clamping sleeve 5 and the equal diameters of installing hole 8, described round end spiral shell
The front end of the body of rod of bolt 1 is provided with square toes 9.
Utility model works process:
The body of rod 7 in the course of the work, is inserted rubber by the novel single-side bolt fastener of a kind of easy accessibility of this utility model
Gum cover 12, insertion depth is that the gap ensureing between clamping sleeve 5 and baffle element 4 is available for baffle element 4 and change in location occurs, so
After unilateral bolt fastener inserted installing hole 8, until baffle element 4 passes fully through the rear end of installing hole 8, now, elastomer 3 is extensive
Baffle element 4 is supported by multiple normal condition, then fixes snap bolt 1 and drives fastener 6 to rotate by screwing tool, until
Baffle element 4 is compressed by clamping sleeve 5, takes away screwing tool, then rotation set is fixed nut 10 and tightens on the body of rod of snap bolt 1,
During insertion, due to the deformation of elastomer 3 so that baffle element 4 occurs change in location, it is impossible to stop, due to rubber sleeve 12 with
There is frictional force between the body of rod 7, ring set 2 will not travel forward, and during dismounting, lays down fixing nut 10, fixing fastener 6, and turns
Dynamic snap bolt 1, makes snap bolt 1 move in installing hole 8, until the gap between round end and the baffle element 4 of snap bolt 1
It is available for baffle element 4 and change in location occurs, then pull out unilateral bolt fastener, due to rubber sleeve 12 and the body of rod 7 during pull-out
Between there is frictional force, ring set 2 will not rearward movement, compared with prior art, it is possible to realize monolateral enforcement terminal operation, also may be used
As required, conveniently remove and install, reusable.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any new to this practicality
