Abstract
The utility model provides a kind of pre-embedded bolt fixing device, including base, annular groove is provided with the bottom surface of the base, the annular groove is embedded with magnetic core, bolt is also equipped with the base, the bolt is engaged with first gear, the first gear engages second gear, the second gear drives rotating wheel, the rotating wheel agrees with cam, the cam is in contact with push rod, the push rod is slidably arranged in the slideway in base, when the bolt rotates, push rod can move along parallel to bolt axis direction, realization is skidded off or withdrawn from the slideway.The utility model is simple in construction, and stability is high during use, the more aobvious convenience in dismounting, as long as rotating bolt, you can push rod is moved along parallel to bolt axis direction, realizes and is skidded off from slideway, fixing device can be ejected, therefore extend service life, greatly reduce production cost.
Description
Technical field
A kind of production auxiliary equipment of construction material is the utility model is related to, more particularly to a kind of pre-embedded bolt fixes dress
Put.
Background technology
Concrete mold is concrete precast block mould, is the concrete finished product according to specific dimensions specification custom-made
Mould.Concrete mold carried out the production of beam column built from concrete using concrete wood formwork in the past, and such a method not only produces slowly,
Efficiency is low, can not reuse and can not meet the basic demand for fixing factory's prefabricated production.So with now existing
Large-scale use and development for precast concrete, the use of new technology of preparing, are proposed more to concrete mold
It is required that.Existing auxiliary fixing device is mostly complicated or using effect is bad, and be magnetic auxiliary fixing device again, although
Certain fixed effect can be obtained, but is found in use, it is more inconvenient when dismantling fixing device after casting terminates.
It is due to that ferromagnetic absorption affinity is larger, it is necessary to apply larger active force, is easily destroyed the Stability Analysis of Structures of fixing device itself
Property, cause working service cost higher.
Utility model content
The purpose of this utility model is to solve technical problem involved in background technology, there is provided a kind of pre-buried spiral shell
Bolt fixing device.
The utility model discloses a kind of pre-embedded bolt fixing device, including base, set on the bottom surface of the base
Annular groove is equipped with, the annular groove is embedded with magnetic core, and bolt is also equipped with the base, and the bolt is engaged with the first tooth
Wheel, the first gear engage second gear, and the second gear drives rotating wheel, and the rotating wheel agrees with cam, described convex
Wheel is in contact with push rod, and the push rod is slidably arranged in the slideway in base, and when the bolt rotates, push rod can
Along being moved parallel to bolt axis direction, to realize and skid off or withdraw from the slideway.
Preferably, the side of the magnetic core is provided with adhesive layer, and the side of the adhesive layer is in contact with magnetic core, opposite side
It is in contact with the cell wall of annular groove.
Preferably, the base is provided with top plate and bottom plate, and oblique landslide is provided between the top plate and bottom plate.
Preferably, the magnetic core is burnt paper as sacrificial offerings by ceramics and magnetized aftershaping through high energy.
Preferably, the push rod is symmetrical as symmetry axis using the axis of bolt.
In summary, the utility model has the advantage that：
The utility model is simple in construction, and stability is high during use, the more aobvious convenience in dismounting, as long as rotating bolt, you can
Push rod is moved along parallel to bolt axis direction, realizes and is skidded off from slideway, fixing device can be ejected, therefore
Service life is extended, greatly reduces production cost.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of the present embodiment；
Fig. 2 is the isometric view of the present embodiment.
Embodiment
As shown in Figure 1-2, a kind of pre-embedded bolt fixing device, including base 1, set on the bottom surface of the base 1
There is annular groove 11, the annular groove 11 is embedded with magnetic core 2, and bolt 3 is also equipped with the base 1, and the bolt 3 is engaged with
One gear 41, the first gear 41 engage second gear 42, and the second gear 42 drives rotating wheel 5, the contract of rotating wheel 5
Cam 6 is closed, the cam 6 is in contact with push rod 7, and the push rod 7 is slidably arranged in the slideway 12 in base 1, when
Push rod 7 can move along parallel to the axis direction of bolt 3 when the bolt 3 rotates, and realize and skid off or receive from the slideway 12
Return.
The side of the magnetic core 2 is provided with adhesive layer 21, and the side of the adhesive layer 21 is in contact with magnetic core 2, opposite side
It is in contact with the cell wall of annular groove 11.
The base 1 is provided with top plate 13 and bottom plate 14, and oblique landslide 15 is provided between the top plate 13 and bottom plate 14.
The magnetic core 2 is burnt paper as sacrificial offerings by ceramics and magnetized aftershaping through high energy.The push rod 7 is symmetrical as symmetry axis using the axis of bolt 3.
Described above is only to explanation of the present utility model so that those of ordinary skill in the art's can completely implements this
Scheme, but be not to limitation of the present utility model, those skilled in the art can be as needed after this specification is read
The modification of no creative contribution is made to the present embodiment, these are all without creative modification.But as long as in this practicality
All protected in new right by Patent Law.
