Description
[technical field]
This utility model relates to the unilateral bolt fastener of a kind of easy accessibility, belongs to civil construction project, mechanical assembly
Technical 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, and the monolateral bolt proposing a kind of easy accessibility is tight
Firmware, 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 unilateral bolt fastener of a kind of easy accessibility, including round end
Bolt, ring set, some elastomers, some baffle elements, fixed cover, body, groove and spring, on the body of rod of described snap bolt by
Front to back is arranged with threaded fixed cover, slidably ring set, spring and threaded body successively, described ring set
Being evenly distributed with elastomer on periphery, described elastomer is provided with baffle element, and described baffle element with the connection end of elastomer is
Arcuate shape, the front end of described fixed cover is provided with connector, described connector is arranged with and turns set, and the front end of described body sets
Having the groove accommodating spring, the front end of described spring is fixing with ring set to be connected, and the rear end of described spring is fixedly mounted in groove.
As preferably, the diameter of described fixed cover and the equal diameters of installing hole.
As preferably, before and after described baffle element, two ends are concordant with two ends before and after ring set respectively.
As preferably, the cross section of described connector is regular polygon shape.
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: this utility model is in use, it is ensured that conflict at snap bolt in the rear end of body
Round end on, and leave certain interval between fixed cover and ring set and be available for baffle element change in location, then by tight for monolateral bolt
Firmware inserts installing hole, until baffle element passes fully through the rear end of installing hole, now, elastomer recovers normal condition to baffle element
It is supported, then by turning set drive fixed cover rotation, until baffle element is compressed by fixed cover, takes away and turn set, 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 baffle element occurs position
Change, it is impossible to stop, during dismounting, dismantles clamp nut, and fixing snap bolt is by turning set dismounting fixed cover, when fixing
Set loose unloading, to time a certain amount of, promotes snap bolt in installing hole, and ring set travels forward under the action of the spring simultaneously, and passes through
Elastomer drives baffle element together to travel forward, thus occurs in that between baffle element and body and be available between baffle element change in location
Every, then pull out unilateral bolt fastener, compared with prior art, it is possible to realize monolateral enforcement terminal operation, also can be according to need
Want, conveniently remove and install, reusable.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the unilateral bolt fastener of a kind of easy accessibility of this utility model；
Fig. 2 is the installation schematic diagram of the unilateral bolt fastener of a kind of easy accessibility of this utility model.
In figure: 1-snap bolt, 2-ring set, 3-elastomer, 4-baffle element, 5-fixed cover, 6-connector, 7-turn set,
8-installing hole, 9-square toes, 10-fix nut, 11-body, 12-groove, 13-spring.
[detailed description of the invention]
Refering to Fig. 1,2, the unilateral 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, fixed cover 5, body 11, groove 12 and spring 13, on the body of rod of described snap bolt 1 by
Front to back is arranged with threaded fixed cover 5, slidably ring set 2, spring 13 and threaded body 11 successively, described
Being evenly distributed with elastomer 3 on the periphery of ring set 2, described elastomer 3 is provided with baffle element 4, described baffle element 4 and elastomer
The connection end of 3 is arcuate shape, and the front end of described fixed cover 5 is provided with connector 6, described connector 6 is arranged with and turns set 7,
The front end of described body 11 is provided with the groove 12 accommodating spring 13, and the front end of described spring 13 is fixing with ring set 2 to be connected, described bullet
The rear end of spring 13 is fixedly mounted in groove 12, the diameter of described fixed cover 5 and the equal diameters of installing hole 8, described baffle element 4
Before and after two ends concordant with two ends before and after ring set 2 respectively, the cross section of described connector 6 is regular polygon shape, described circle
The front end of the body of rod of hook bolt 1 is provided with square toes 9.
Utility model works process:
The unilateral bolt fastener of a kind of easy accessibility of this utility model in the course of the work, in use, it is ensured that body
Conflicting on the round end of snap bolt 1 in the rear end of 11, and leaves certain interval between fixed cover 5 and ring set 2 and be available for stopping
Body 4 change in location, then unilateral bolt fastener is inserted installing hole 8, until baffle element 4 passes fully through the rear end of installing hole 8, this
Time, elastomer 3 recovers normal condition and is supported baffle element 4, then passes through to turn set 7 drive fixed covers 5 and rotates, until solid
Surely baffle element 4 is compressed by set 5, takes away and turns set 7, then rotation set is fixed nut 10 and tightens on the body of rod of snap bolt 1, inserts
Time, due to the deformation of elastomer 3 so that baffle element 4 occurs change in location, it is impossible to stop, during dismounting, dismantle clamp nut
10, fixing snap bolt 1, by turning set 7 dismounting fixed cover 5, when fixed cover 5 loose unloading is to time a certain amount of, pushes away in installing hole 8
Dynamic snap bolt 1, ring set 2 travels forward under the effect of spring 13 simultaneously, and drives baffle element 4 one in the same direction by elastomer 3
Front motion, thus between baffle element 4 and body 11, occur in that the interval being available for baffle element 4 change in location, then pull out monolateral spiral shell
Bolt securing member, compared with prior art, it is possible to realize monolateral enforcement terminal operation, also can conveniently remove and install as required, can
Reuse.
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
Scheme after type simple transformation belongs to protection domain of the present utility model.
