Abstract
The crab-bolt of a kind of Novel belt tapering of the utility model groove, comprise tightening latch, screw rod, crab-bolt head and cone bar, on described tightening latch, be provided with crab-bolt head, on described tightening latch, be provided with screw thread, the below connection of described tightening latch arranges screw rod, described screw rod and tightening latch joint are provided with annular groove, the lower end of described screw rod is connected with cone bar, described crab-bolt head is semicircle shape, its radius is below 10 centimetres, described tightening latch and screw rod adopt the direct cold-heading molding of motion of accurate Calculation and intense beam mould, and described cone bar lower end surface is provided with three conical surfaces.The utility model is by tightening latch being set and screw rod bilayer is equipped with, and in both joints, the load ability that has effectively increased crab-bolt with the annular groove of tapering is set, and the screw thread of next section of plane can play one and well tightens effect; Spacing good fixing effect, can anti-skidding, and cost is low, and long service life is applied widely, has safe and reliable effect.
Description
Technical field
The utility model relates to a kind of crab-bolt of Novel belt tapering groove.
Background technique
Crab-bolt usually coordinates the effect of playing carrying machine weight and load with concrete pedestal, the tightening latch of crab-bolt in use at present, after clay solidifies, part around tightening latch has just formed a clay shell, when clay has crack to produce, the friction that tightening latch just need to produce by its tapering moves tightening latch in clay shell, thereby produce the effect of further tensioning, so this type of crab-bolt is often suitable for being anchored in the place of bearing tension, but in order to protect coating layer on tapering also will establish a net on tapering, it is protected, the manufacture cost of crab-bolt will be very high like this, and net also can be because cannot not making tightening latch in place by impact when crab-bolt is used.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, use, easy for installation, simple to operate, and cost is low, and long service life is applied widely, has the crab-bolt of the Novel belt tapering groove of safe and reliable effect.
For addressing the above problem, the utility model adopts following technological scheme: a kind of crab-bolt of Novel belt tapering groove, comprise tightening latch, screw rod, crab-bolt head and cone bar, on described tightening latch, be provided with crab-bolt head, on described tightening latch, be provided with screw thread, the below connection of described tightening latch arranges screw rod, described screw rod and tightening latch joint are provided with annular groove, the lower end of described screw rod is connected with cone bar, described crab-bolt head is semicircle shape, its radius is below 10 centimetres, described tightening latch and screw rod adopt the direct cold-heading molding of motion of accurate Calculation and intense beam mould, described cone bar lower end surface is provided with three conical surfaces.
As preferably, described annular groove is the groove with tapering.
As preferably, the tooth angle of described screw thread is 60 degree.
The utility model, through the direct cold-heading molding of motion of accurate Calculation and intense beam mould, is broken through the flat technique of milling machine milling in the past, and mould-forming is enhanced productivity greatly on the one hand, saves production cost, and shape is even on the other hand, stable.It is simple in structure, use, easy for installation, simple to operate, by tightening latch being set and screw rod bilayer is equipped with, and the load ability that has effectively increased crab-bolt with the annular groove of tapering is set in both joints, and the screw thread of next section of plane can play one and well tightens effect; By cone bar is set, can increase when mounted the impact force of crab-bolt.The spacing good fixing effect of the utility model, can anti-skidding, and cost is low, and long service life is applied widely, has safe and reliable effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is worm's eye view of the present utility model.
Embodiment
Consult the crab-bolt of a kind of Novel belt tapering groove shown in Fig. 1 and Fig. 2, comprise tightening latch 4, screw rod 2, crab-bolt 3 and cone bar 5, on described tightening latch 4, be provided with crab-bolt 3, on described tightening latch 4, be provided with screw thread, described tightening latch 4 belows connections arrange screw rod 2, described screw rod 2 is provided with annular groove 1 with tightening latch 4 joints, has effectively increased the load ability of crab-bolt, and the screw thread of next section of plane can play one and well tightens effect; The lower end of described screw rod 2 is connected with cone bar 5, described crab-bolt 3 is semicircle shape, its radius is below 10 centimetres, described tightening latch 4 and screw rod 2 adopt the direct cold-heading molding of motion of accurate Calculation and intense beam mould, described cone bar 5 lower end surfaces are provided with three conical surfaces, can increase when mounted the impact force of crab-bolt.The spacing good fixing effect of the utility model, can anti-skidding.
It should be noted that described annular groove 1 is for the groove with tapering.
Tooth angle that it should be noted that described screw thread is 60 degree.
The utility model, through the direct cold-heading molding of motion of accurate Calculation and intense beam mould, is broken through the flat technique of milling machine milling in the past, and mould-forming is enhanced productivity greatly on the one hand, saves production cost, and shape is even on the other hand, stable.The spacing good fixing effect of the utility model, can anti-skidding, and cost is low, and long service life is applied widely, has safe and reliable effect.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
