Description
【Technical field】
The present invention relates to a kind of detachable fasteners, belong to civil construction project, mechanical assembly technique field.
【Background technology】
It, need to be when carrying out terminal operation for the plain bolt being made of screw rod and nut being commonly used
Screw rod and binding nut are inserted into side, are then tightened nut with tool in the other side, and installation requirement installation personnel is simultaneously in structure
The operation of part both sides.But relative to the installation of more typical opening section component, for such as closed cross-section member and inconvenience
It touches for the wherein component of one side, this bolt generally used is using simultaneously inconvenience.Such as concrete filled steel tube,
Beam-column connection etc., since column section is mostly closed section, plain bolt cannot be operated on both sides, therefore common side
Method can not be installed.Application of the common expansion one-way bolt because being difficult to realize bolt pretightening, fastening effect is also unable to reach larger
Design requirement under load.And the reserved required precision of punching bolt-for-bolt hole in the prior art is especially high, in-site installation
Difficulty is big, and is difficult to apply at side column and corner post node.And in existing unilateral bolt, it is not suitable for large span or big load
Structure, and need more complex installation tool and cumbersome installation steps.
【Invention content】
The purpose of the present invention is exactly to solve the problems of the prior art, proposes a kind of detachable fastener, can realize
Unilateral implementation terminal operation, can also be as needed, easy to disassemble, reusable.
To achieve the above object, the present invention proposes a kind of detachable fastener, including snap bolt, gasket, fastening
Nut and blocking mechanism are arranged with fastening nut, gasket and blocking mechanism on the body of rod of the snap bolt successively from front to back,
The blocking mechanism includes the first body, the second body, several first bearings, several second bearings, fixed mechanism, several first
Connector and several second connectors, the first body is arranged on the body of rod of the snap bolt and is threadedly coupled second set
Body, first body are located at the rear of the second body, and circumferentially the first bearing, institute is distributed in shape for the front end of first body
The first connector for being equipped with and being rotatably connected on the first bearing is stated, circumferentially shape is distributed with second for the rear end of second body
Bearing.
Preferably, the second connector being rotatably connected is equipped on second bearing, second connector
Rear end and the front end of the first connector are rotatably connected, and the front end of second body is equipped with fixed mechanism.
Preferably, if the fixed mechanism includes the tensioning pawl of pedestal and dry elasticity, circumferentially shape divides the tensioning pawl
Front end periphery of the cloth in pedestal.
Preferably, the tensioning pawl and pedestal are integrally formed, the tensioning pawl is the arcuate shape to arch, described
The top of tight pawl exceeds the periphery of pedestal.
Preferably, the diameter of the pedestal is equal with the diameter of the second body.
Preferably, the outer diameter of second body is equal with the diameter of mounting hole.
Beneficial effects of the present invention：In the use of the present invention, unilateral bolt fastener is inserted into mounting hole, and ensure second
The rear end of body is at least concordant with the rear end of mounting hole, then rotates snap bolt, since the second body passes through fixed mechanism
Fixed, to which snap bolt travels forward and the first body is driven to travel forward, the first body drives first by the first bearing
Connector is moved from heeling condition to vertical state, while the first connector drives the second connector from heeling condition to vertical shape
State moves, when the first connector and the second connector state in a vertical shape and when overlapping, the first connector and the blocking of the second connector
In the rear end of mounting hole, the second body and first the first connector of body pair and the second connector are also in clamp position, at this point, turning
Dynamic snap bolt is relatively laborious compared with before, then fastens fastening nut, when disassembly is desired, come loose fastening nut, so
Negative direction rotation snap bolt can be taken out out of mounting hole until unilateral bolt fastener afterwards, compared with prior art, Neng Goushi
Existing unilateral implementation terminal operation, can also be as needed, easy to disassemble, reusable.
The feature and advantage of the present invention will be described in detail by embodiment combination attached drawing.
