Abstract
A speedy locking fastener comprises a fastener body and a cover plate. One end of the cover plate is hinged on the fastener body while the other end is connected to the fastener body through a locking shaft; one end of the locking shaft is a hexagonal head while the other end is a T-shaped head; opposite surfaces of the hexagonal head and the T-shaped head are double helix sides; the surfaces of the fastener body or the cover plate contacting with the double helix sides are the double helix sides having same helical angle and adverse spiral direction. The utility model can rapidly lock or release the connected steel tube, promotes the speed of assembling falsework, promotes working efficiency to 5 times, needs no fine thread structure in the fastener, has simple structure, decreases the maintenance work load and lowers the use cost.
Description
Technical field
The utility model relates to a kind of construction equipment, particularly a kind of steel tube scaffold clasp.
Background technology
Building operations, and usually need to use the scaffold building working platform in the engineering construction processes such as municipal administration, water conservancy, chemical industry, metallurgy, coal and boats and ships, the main material of setting up scaffold generally is that external diameter is steel pipe and the fastener of 48.3mm, connect steel pipe with fastener and promptly set up scaffold, therefore, whether fastener connects reliable, safe, firmly most important to scaffold, whether the dismounting of fastener is very big to the speed influence that scaffolds erecting easily and fast, also concerns working strength of workers.The main fastener that uses has three kinds: be used for that the steel pipe butt joint connects to clasp, be used for steel pipe right-angle coupler connected vertically, be used for the rotary buckle of the arbitrarily angled connection of steel pipe.The scaffold clasp that uses in a large number is 48-1 type fastener at present, and the main feature of this fastener clamping steel pipe is two semi-circular clips, and internal diameter is slightly less than outer diameter of steel pipes, and on one side for hinge connects, another side is that bolt connects, and by fastening bolt, steel pipe is clamped.In use there is following defective in this fastener: the one, and assembling and dissembling speed is slow, and production efficiency is low; The 2nd, mortar falls to amassing on screw thread easily in work progress, expose to the sun and rain for a long time, screw thread easy-to-rust on the screw bolt and nut, make its mounting or dismounting difficulty even can't install and remove, have only the method rethreading that embathes with kerosene, or destructiveness removes it, again preparation bolt, the nut scrapping or lose, maintenance workload is big, the use cost height.
The utility model content
The utility model aims to provide a kind of quick lock fastener, and under the situation that does not change conventional fastener basic structure, lock fastener improves locking speed fast, thereby improves work efficiency, reduces maintenance workload, reduces use cost.
The technical solution of the utility model is: a kind of quick lock fastener, comprise fastener body and cover plate, cover plate one end is connected on the fastener body by hinge, the other end links to each other with fastener body by lock shaft, described lock shaft one end is a hexagonal head, the other end is a T shape head, and hexagonal head and T shape head two surfaces in opposite directions are the double helix face, is same-handed angle but the opposite double helix face of rotation direction with the fastener body of this helicoid contact or lid surface.
Further, two surfaces in opposite directions of described hexagonal head and T shape head are the double helix face, and two helicoid rotation directions are opposite.
Preferably, the helicoid of a described hexagonal head or a T shape inner surface is the double helix face.
Further preferred, two surfaces in opposite directions on described hexagonal head and the T shape head all are double helix faces.
The utility model can lock the steel pipe that it connected or unclamp fast, improves the speed of setting up scaffold greatly, can improve about 5 times of work efficiency, has exempted the fine thread structure in the existing fastener, and is simple in structure, reduced maintenance workload, reduced use cost.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is locking bearing pin schematic diagram.
Among the figure: the 1-cover plate, 2-locks bearing pin, 3-fastener body, 21-hexagonal head, 22-T shape head, 23-helicoid, 24-axis body.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, lock fastener comprises fastener body 3 and cover plate 1 fast, and cover plate 1 one ends are connected on the fastener body 3 by hinge, and the other end links to each other with fastener body 3 by locking bearing pin 2, connects the rectangular opening of locking bearing pin on the fastener body 3.As shown in Figure 2, lock shaft 2 one ends are hexagonal head 21, the other end is a T shape 22, the end face of T shape 22 is rectangular, hexagonal head 21 and T shape 22 two surfaces in opposite directions are double helix face 23, double helix face 23 is around axis body 24 rotations, and the fastener body or the lid surface that contact with this double helix face 23 are the double helix face that helical angle is identical, rotation direction is opposite.Further, two surfaces in opposite directions of hexagonal head 21 and T shape 22 are helicoid, and the rotation direction of two helicoids is opposite, and locking is quicker like this.Preferably, the helicoid on hexagonal head 21 or T shape 22 surface is the double helix face, and the locking back is stressed more balanced.Further preferred, all are double helix faces on hexagonal head 21 and the T shape 22, so not only locking fast, and stress equalization, reliable lock.
During installation, cover plate 1 is covered steel pipe, the T shape 22 of locking bearing pin 2 is inserted in the rectangular opening of fastener bodies 3, twist the hexagonal head 21 of locking bearing pin 2 with spanner, rotation 120-160 degree just can be finished the locking to steel pipe.During dismounting,, just can unclamp fastener as long as oppositely twist the 120-160 degree.
This structure can be applicable to right-angle coupler, to clasp and rotary buckle, only need change the bolt of existing fastener into the locking bearing pin, on fastener body, process rectangular opening, and on fastener body and cover plate, get final product with the locking pin synapsis processing helicoid that is coupling.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
