Abstract
The utility model discloses a double -disk anchor device, outside rotating screw spindle is guaranteed to insert accomplish fluently in advance downthehole with in anchor piece an and the anchor piece b income casing with the device, inserts to begin to twist to the extreme position after and moves the screw spindle, and is peaceful during to extreme position, because of anchor piece an and anchor piece b under the pressure of screw spindle, slide in spout an and spout b, outside the ejecting casing, good the device is fixed to the formation dihedral. The casing top is the horn shape, conveniently inserts the wall body. Since the nut be the welding in the casing, can firmly fix screw thread the shaft position, prevent that the screw spindle is not hard up and device that lead to is insecure. Operating personnel is in the hand district application of force when using, and hand district is net or dull polish structure, can increase frictional force to the human cost has been reduced. When needs take out the device, to the external rotation screw spindle, anchor piece an and anchor piece b take in the casing respectively under spring an and spring b's spring action in, reduce the resistance of choosing to reduce the human cost.

Background technology
On market today, normally used riveting device is setscrew, mechanical swelling after setscrew inserts body of wall
Rate about reaches 20%-30%, reaches the effect of rivet clasp, but be necessary for needs take out setscrew when with claw hammer or
Vice is extracted, and expends a large amount of manpower, and also the most easily takes out, and serious also needs to destruction body of wall.The thinnest
Must extract with claw hammer or vice when taking out setscrew on the body of wall of pine, labor intensive, and also not necessarily take out.
If body of wall is concrete or solid brick, cannot take out, it is necessary to just can go out to take out with cutting tool or destruction body of wall at all.
Summary of the invention
In order to solve problem above, this utility model patent provides one and facilitates insertion into body of wall and convenient taking-up, also
Improve anti-pulling and the riveting device of weight capacity.
A kind of double-disk riveting device, it is characterised in that: include housing, rivet clasp sheet a, rivet clasp sheet b, thread spindle and spiral shell
Female；Described rivet clasp sheet a and rivet clasp sheet b all angular water-drop-shapeds in one side in one side semicircle, and size is identical；Described rivet clasp sheet a and
The semicircle home position of rivet clasp sheet b is equipped with through hole；Described housing is hollow cuboid, and two ends are provided with opening；Described shell
Internal side is provided with fixing axle；Described fixing axle makes rivet clasp sheet a, rivet clasp sheet b and shell through the through hole of rivet clasp sheet a and rivet clasp sheet b
Body couples；Closed end one end of described housing stretches out angulation, and other end center is provided with screwed hole；Described housing
Be fixedly connected nut in screwed hole position；Described thread spindle couples with nut thread through screwed hole through housing；Described spiral shell
Stricture of vagina axle one end in housing is provided with oblique angle chute a and oblique angle chute b；The angle end of described rivet clasp sheet a is stuck in oblique angle chute a, institute
The angle end stating rivet clasp sheet b is stuck in oblique angle chute b；It is additionally provided with spring a on described rivet clasp sheet a；Described spring a one end and rivet clasp sheet
A couples, and the other end is fixedly connected at case inside, makes the angle end stress of rivet clasp sheet a be stuck in chute a；On described rivet clasp sheet b also
It is provided with spring b；Described spring b one end couples with rivet clasp sheet b, and the other end is fixedly connected at case inside, makes the angle end of rivet clasp sheet b
Stress is stuck in chute b；Described thread spindle is additionally provided with hand steered district in one end of hull outside.
It provides the benefit that: instead of traditional setscrew, simple in construction, and housing tip is horn shape, it is simple to insert wall
Body, when taking out this device, outside turn thread spindle, rivet clasp sheet a and rivet clasp sheet b takes in shell under the effect of spring a and spring b
Internal, can easily take out will not be by external resistance.The nut being fixedly connected in housing can stationary threaded shaft, it is not necessary to screw thread
Axle is fixed further, saves step, the most just saves human resources.Tension pull out force, expansion rate more than 300% can be increased.
Further, described through hole diameter is more than fixing shaft diameter, and rivet clasp sheet can be with fixing axle for the center of circle at shell
Internal rotate freely.
It provides the benefit that: after thread spindle rotates and contacts with rivet clasp sheet b as rivet clasp sheet a, rivet clasp sheet a and rivet clasp sheet b
Can slide in chute a and chute b respectively, make rivet clasp sheet a and rivet clasp sheet b eject outside housing, can firmly this device card be existed
In wall hole.
Further, described hand steered district is grid or frosted structure.
It provides the benefit that: thread spindle in order to prevent rivet clasp sheet from loosening, must be tightened, now exist by operator in use
Hand steered district exerts a force, it is possible to increase frictional force, thus reduces human cost.
Further, described housing, rivet clasp sheet, thread spindle, pad and nut are metal material.
It provides the benefit that: because riveting device is possibly used for outdoor, and metal material not only rigidity is preferable, and anticorrosive
Oxidation resistance is excellent, substantially prolongs the service life of this device.
Further, described nut-welding is in housing.
It provides the benefit that: the fastness of welding is very good, can good stationary threaded shaft, prevent thread spindle from loosening.
Accompanying drawing explanation
Fig. 1 is Facad structure perspective view of the present utility model；
Fig. 2 is thread spindle top view.
Detailed description of the invention
Come below in conjunction with the accompanying drawings utility model patent is described in detail.
As shown in Figure 1 to Figure 2, hole at metope in advance, outside turn thread spindle 3, it is ensured that by rivet clasp sheet a4 and rivet clasp sheet
In b5 income housing 1, this device is inserted in the hole accomplished fluently in advance, starts to turn thread spindle 3 after being inserted to extreme position, the most extremely
During extreme position, because rivet clasp sheet a4 and rivet clasp sheet b5 is under the pressure of thread spindle 3, slides in chute a10 and chute b11, eject
Outside housing 1, form dihedral and fix this device.Housing 1 top is horn shape, convenient insertion body of wall.Owing to nut 8 is welded to
In housing 1, the position of thread spindle 3 can be securely fixed, prevent thread spindle 3 from loosening and the device that causes is insecure.Behaviour
