Abstract
A regulated molding board top pole comprises a top pole bottom segment and a top pole upper segment, wherein the upper part of the top pole bottom segment is provided with outer screw thread and matched with a turnbuckle, and the top pole upper segment is equipped with a positioning hole and matched with a positioning bolt. The utility model is characterized in that the outer screw thread on the upper part of the top pole bottom segment is the outer screw thread standing out of the outer wall of the bottom segment, and the turnbuckle is longer; and/or the rear part of the positioning bolt is longer and bent into the arc around the top pole upper segment. The utility model has reasonable design and simple structure, the outer screw thread of the top pole bottom segment is not shown up and unable to drop the sands. Turning the turnbuckle is convenient and saves the labor. The rear part of the positioning bolt is longer and bent around the top pole upper segment, thereby not only being able to conveniently exchange the positioning hole, but also being unable to fall apart from the upper segment of the top pole, which avoids the losing of the positioning bolt.
Description
Technical field: the utility model relates to a kind of adjustable template fore-set that supports the building concrete template.
Background technology: in the prior art, application number is 02231782.1 patent disclosure, and a kind of name is called " adjustable template fore-set " technology, this technology comprises seat top and push rod, and the top on seat top and the bottom of push rod can move up or down push rod by being threaded.The extension push rod also is installed on the push rod, extends push rod and be installed on the push rod by extending push rod jack, push rod jack and latch.Realized the coarse adjustment and the fine setting of push rod height, this technology can improve the efficiency of construction that supports the building concrete template, also is convenient to dismounting and use repeatedly.But this template push rod technology, its structure more complicated when the fine setting of height, must be rotated push rod and realize simultaneously, and push rod rotates must drive again and extends the push rod rotation, regulates very effort and inconvenience; In addition, employed latch is a straight pin, is easy to lose in dismounting.Application number is 200520088943.0, name is called the patent of " fore-set of living ", also discloses a kind of adjustable template fore-set, and this fore-set has the column of a band bottom plate, be fitted with the guide pillar of band mounting plate in the column, and be connected with fastening screw by the locating hole on the guide pillar, guide groove on the column.Column is provided with external screw thread, and is furnished with nut with handles.This fore-set has been realized the coarse adjustment and the fine setting of push rod height, and structure is also fairly simple.But this fore-set on the height fine tuning structure, because the external screw thread on the column is in naked state, is easy to fall to going up and adhere to some silts, even causes rust corrosion.When highly fine setting was regulated, the rotation of nut is the difficulty effort very.A side has handle on the nut in addition, and therefore other strength during rotation require great effort more.In addition, its fastening screw is a straight pin, and has adopted the scheme of putting with the rope bolt, though this has solved the problem of losing easily, scheme is comparatively loaded down with trivial details.
Summary of the invention: the purpose of this utility model provides a kind of novel adjustable template fore-set, in order to overcome the above-mentioned drawback of existing in prior technology effectively.The utility model is to improve to realize on the basis of prior art template fore-set, it comprises the supporting plate of joint on the pallet, fore-set of fore-set coxopodite and lower end thereof and upper end thereof, fore-set coxopodite top is provided with external screw thread, and is fitted with tapped swivel nut, and swivel nut is provided with handle; Joint has locating hole on the fore-set, is fitted with fastening screw.The external screw thread that it is characterized in that said fore-set coxopodite top is the external screw thread of outstanding coxopodite outer wall, and said swivel nut is longer, and its length is not less than the length that adds a locating hole distance at the bottom of the said external screw thread along the length on the fore-set coxopodite; And/or said fastening screw afterbody is longer, and joint is bent into arc on fore-set, and its opening is less than saving diameter on the fore-set, and the distance between fastening screw top and its extended line and the afterbody arc intersection point is slightly larger than and saves diameter on the fore-set.By the handle rotary threaded sleeve, swivel nut can prop up the top fastening screw and drive to save on the fore-set and move up and down, and realizes that the trace of the height of the utility model fore-set is regulated.
The utility model is reasonable in design, and is simple in structure, because swivel nut is longer, even be fine-tuning to the fine setting peak, the external screw thread that withstands coxopodite can not expose yet, and can not fall to going up silt, also can not cause corrosion.When highly finely tuning, rotary threaded sleeve is convenient and strength-saving.Its fastening screw afterbody is longer, and joint is bent into arc on fore-set, its opening is less than saving diameter on the fore-set, distance between fastening screw top and its extended line and the afterbody arc intersection point is slightly larger than and saves diameter on the fore-set, both can change locating hole easily, can not deviate from again, thereby effectively avoid losing of fastening screw from the joint of fore-set.
Description of drawings: accompanying drawing is a structural representation of the present utility model
The specific embodiment: accompanying drawing has provided specific embodiment of the utility model, with reference to the accompanying drawings, 2 is the utility model template fore-set coxopodites among the figure, fore-set coxopodite 2 lower ends have pallet 1, top to be provided with the external screw thread of outstanding coxopodite outer wall, and be fitted with swivel nut 4, this swivel nut 4 is longer, and its length is not less than at the bottom of the above-mentioned said external screw thread along the length that adds a locating hole distance to the length of fore-set coxopodite 2 upper ends, and swivel nut is provided with handle; The 8th, save on the fore-set, there is supporting plate 9 its upper end, the lower end is plugged in the fore-set coxopodite 2, have some locating holes 7 on the joint 8 on the fore-set, be fitted with fastening screw 6, these fastening screw 6 afterbodys are longer, and joint 8 is bent into arc on fore-set, its opening is less than the diameter of joint 8 on the fore-set, and the distance between fastening screw 6 tops and its extended line and the afterbody arc intersection point is slightly larger than the diameter of joint 8 on the fore-set.
For avoiding silt to drop down onto in the swivel nut 4 better, can be provided with a dust ring 5 above the said swivel nut 4, be set in and save on the fore-set on 8, the external diameter of joint 8 is corresponding on the internal diameter of this dust ring 5 and the fore-set, and external diameter is slightly larger than the external diameter of swivel nut 4.
At highly micro-timing, rotate other strength and firmly convenient for preventing swivel nut 4, the handle 3 on the said swivel nut 4 can be and is the bilateral handle.
