Abstract
The utility model discloses a fastener structure for improving a concrete blinding. The fastener structure for improving the concrete blinding comprises a fastener, a lock part, and a spring. One end of the fastener is provided with a bayonet lock and a bayonet is placed in an inner concave of the end. The bayonet is adaptive to the concrete blinding through a fixing pipe and the bayonet comprises a sleeve hand grip. The sleeve hand grip comprises a vertically connective hand grip and a vertically connective sleeve. The other end of the lock part is provided with a sleeve pipe. The sleeve pipe extends along an extension direction of the bayonet. The sleeve pipe is connected with the sleeve to form a spring cavity in a sleeve mode. The spring is placed in the spring cavity. Two ends of the spring are pressed on a wall of an inner cavity of the spring cavity. One end of the lock part is provided with a lock pin. The other end of the lock part is penetrated through the spring and connected with the sleeve hand grip. By the adoption of splicing templates of the fastener structure for improving the concrete blinding, the fixed pipe is locked by the bayonet to enable the bayonet lock to be locked in a groove of the concrete blinding. The hand grip pressed enables the bayonet lock to be pressed in the other groove of the surface of the concrete blinding. The hand grip rotated enables the bayonet lock to be locked in the groove. After the handle being loosening, the spring bouncing enables the hand grip pipe and the concrete blinding to be fixed tightly. Due to the spring is placed in the spring cavity, the spring cannot be easily corroded by the concrete and muddy water and can work normally. Service life is prolonged and a potential safety hazard is removed.

In order to address the above problem, the applicant has applied for " a kind of ready-package concrete blinding fastener device ", it comprises the fastener that is installed on the stationary pipes that fixing splicing concrete blinding uses, and is located on this fastener the latch fitting that modular unit is fastened on the stationary pipes.Fastener directly is connected on the stationary pipes that fixing splicing concrete blinding uses, and latch fitting is fixed on concrete blinding on the stationary pipes after passing fastener.
But, one end of above-mentioned fastener is fastened on the stationary pipes, the other end of fastener is fastened on the concrete blinding by latch fitting, since the fastener two ends respectively with the corresponding formation of stationary pipes and concrete blinding assembly relation, so, in order further to improve the efficiency of loading and unloading of concrete blinding, be necessary to improve the structure of latch fitting.
In order to address the above problem, the applicant has applied for " a kind of press fastening type loads and unloads concrete blinding tube clamps device soon ", it comprises fastener, latch fitting and adjusting screw(rod) or adjusting nut, one end indent of fastener forms the card division, this card division has the bayonet socket that is interlocked with stationary pipes with concrete blinding, latch fitting is supported with rotation by spring and is loosened the other end that the mode of supporting stationary pipes is located in this fastener, and this latch fitting is along the depth direction setting of above-mentioned bayonet socket; Adjusting screw(rod) or adjusting nut are arranged on the outer surface of above-mentioned fastener, and this adjusting screw(rod) is along the depth direction setting of the bayonet socket of described fastener.
But, because above-mentioned spring housing is outside latch fitting, spring can get rusty by burn under the effect of concrete, muddy water, even generation bonding phenomenon, latch fitting spring can not be played a role, and then causes latch fitting can not be pressed in the lip-deep groove of concrete blinding, even can be pressed in the above-mentioned groove, because spring can not normally rebound, latch fitting can not tightly be snapped together stationary pipes and concrete blinding.The polylith concrete blinding that is connected together by tube clamps device, stationary pipes so just exists potential safety hazard.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of improvement concrete blinding fastener structures that can prevent the spring rust corrosion.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of improvement concrete blinding fastener structures, comprise fastener, latch fitting and spring, one end of fastener is provided with bayonet lock and this end indent forms bayonet socket, bayonet socket and concrete blinding are suitable with stationary pipes, also comprise the cover handle, cover is comprising handle and the sleeve that is vertically connected on together, the other end of described fastener is provided with sleeve pipe, sleeve pipe is along the depth direction setting of described bayonet socket, sleeve pipe and jacket casing are connected together and form a spring cavity, described spring is arranged in this spring cavity, and two free ends of spring are supported respectively on the internal chamber wall of spring cavity; One end of described latch fitting is provided with lock pin, and the other end of described latch fitting links together with the cover handle after passing spring.
The joining place of described fastener and described bayonet lock is formed with reducing diameter part, and the outer wall that described fastener points to described bayonet lock is provided with reinforcement.
The inwall of described sleeve pipe and described sleeve protrudes respectively the formation positioning step, and two described free ends of described spring respectively correspondence are supported on positioning step.
Described jacket casing is outside described sleeve pipe.
Described latch fitting links together by bearing pin and described cover handle.
After adopting said structure, a kind of improvement concrete blinding of the present utility model has following beneficial effect with fastener structures: during the splicing concrete blinding, at first bayonet socket is blocked stationary pipes and bayonet lock is sticked in the lip-deep groove of concrete blinding, then press down the lock pin that handle makes the latch fitting end and compress into lip-deep another groove of concrete blinding, and the rotation handle is stuck in the above-mentioned groove lock pin, unclamp the bounce-back of handle rear spring, thereby the stationary pipes in the bayonet socket and concrete blinding tightly are fixed together.Because spring is arranged in sleeve pipe and the formed spring cavity of sleeve, be difficult for by concrete, muddy water corrosion, spring can normally play a role, thereby has prolonged the life-span of fastener structures, has eliminated potential safety hazard.
