Abstract
The utility model is to belong to quick locking nut field, particularly relates to the quick locking nut of construction formwork keel tension screw mandrel.It is characterized in that: this nut is made up of two and half block teeth, one end of two and half block teeth is hinged by articulated elements, one end, opposite of two halves block teeth hinged place all have one with jointed shaft and the perpendicular groove of screw central axis, one end of bolt is hinged in the groove of half block teeth, and the other end of bolt is connected with locking member.Compared with prior art the utlity model has following significant advantage: dismounting is fast, without a-circle-by-a-circle spin nut, efficiency is high, and speed is fast, and labour cost is low; Owing to adopting screw mandrel tooth apart from little, and after wing nut locking, two halves block teeth hug screw mandrel, are difficult for shake pine when the high-frequency strenuous vibration of mechanical vibrator, thereby have greatly reduced the phenomenon of burst-mode spillage.
Description
Technical field
The present invention belongs to quick locking nut field, particularly relates to the quick locking nut of construction formwork keel tension screw mandrel.
background technology
Before the present invention, there is a kind of quick locking nut apparatus (application number: 201120488448.4), he has a groove on the basis of conventional nut, has through hole in the direction of vertical channel, by through hole, one cam handle type Quick-dismantle component is housed.This device cannot be along the axial fast moving of screw mandrel, and must a-circle-by-a-circle turn efficiency low, cost of labor be high.In order to raise labour efficiency, construction formwork keel tension screw mandrel and nut have strengthened helical angle at present, although this improvement is to certain help of raising labour efficiency, DeGrain.Also there is the problem that another is new simultaneously, exactly in the time of building operations because the high-frequency strenuous vibration nut of mechanical vibrator is usually quaked loose, the not clamping burst-mode spillage that causes of template.
The post beam size of a certain building that again can not be corresponding single as screw mandrel, he must be the post beam size that adapts to certain size scope, could reduce to greatest extent screw mandrel length specification.So usually will make the screw mandrel that exposes long, increase greatly the workload of spin nut, cause cost of labor significantly to increase, inefficiency.
summary of the invention
Object of the present invention will overcome the deficiencies in the prior art exactly, provide a kind of can be along screw axis to fast arbitrarily mobile, efficiency is high, speed is fast, reduces greatly the quick locking nut of the construction formwork keel tension screw mandrel of labour cost.
In order to realize above-described object, the present invention is achieved through the following technical solutions: the quick locking nut of construction formwork keel tension screw mandrel, formed by two and half block teeth, one end of two and half block teeth is hinged by articulated elements, one end, opposite of two halves block teeth hinged place all have one with jointed shaft and the perpendicular groove of screw central axis, one end of bolt is hinged in the groove of half block teeth, and the other end of bolt is connected with locking member.
In further technical scheme, described two and half block teeth hinged be hinged on respectively on an intermediate mass or two and half block teeth directly hinged by hinge pin.
In further technical scheme: described locking member is wing nut or cam handle type Quick-dismantle component.
Compared with prior art, the present invention has following significant effect: two and half block teeth are opened, can rapidly the present invention be placed into the end face of the workpiece that is locked, then close up two and half block teeth and screw locking, masterplate can be strained.Without a-circle-by-a-circle spin nut, efficiency is high, and speed is fast, and labour cost is low.
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail.

Detailed description of the invention
As shown in Figure 1, the quick locking nut of construction formwork keel tension screw mandrel, formed by half block teeth a1 and half block teeth b2 two and half block teeth, each one end of half block teeth a1 and half block teeth b2 is hinged by articulated elements, one end, opposite of two halves block teeth hinged place all have one with jointed shaft 4 and the perpendicular groove 6 of screw central axis 5, one end of bolt 7 is hinged in the groove 6 of half block teeth a1, and the other end of bolt 7 is connected with locking member wing nut 8.
Further, each one end of half block teeth a1 and half block teeth b2 is all hinged on an intermediate mass 3 by hinge pin axle.
Be described as follows according to Fig. 2 to Fig. 8 to concrete application: first the present invention 13 is opened to the state as Fig. 8, and then the end face that the present invention 13 is installed to need locking keel 10 along screw mandrel 11 as shown in Figure 4, then by Fig. 4 direction of arrow, half block teeth are closed up to the state to Fig. 5, forward the bolt 7 that is rotary with wing nut 8 to Fig. 6 position by Fig. 5 direction of arrow afterwards, by Fig. 6 arrow a direction wing nut 8 of prewhirling, screw whole quick locking nut by arrow b direction again, finally screw wing nut 8 by Fig. 7 direction of arrow.
Compared with prior art the present invention has following significant advantage: dismounting is fast, and without a-circle-by-a-circle spin nut, efficiency is high, and speed is fast, and labour cost is low; Because screw mandrel 11 teeth that adopt are apart from little, and after wing nut 8 lockings, two halves block teeth hug screw mandrel 11, are difficult for shake pine when the high-frequency strenuous vibration of mechanical vibrator, thereby have greatly reduced the phenomenon of burst-mode spillage.
The foregoing is only preferred embodiment of the present invention, all equalizations of doing according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
