Description
Technical field
The utility model relates to building fancy face plate dry hanging technology field, especially a kind of decoration panel built-in screw type back of the body stud structure.
Background technology
By slotting at the entity back side in the cladding industry of building fancy face plate, again metal hanger is implanted entity through fluting, but the main defect of existing structure is: construction labour intensity is large, install regulate loaded down with trivial details, comparatively large to the destructiveness of entity, easily cause entity and body of wall that difficulty is installed.Existing back of the body bolt existing defects has manufacture craft more complicated, and cost of production is high, installs inconvenient, affects construction operation efficiency.
Utility model content
The purpose of this utility model be to provide a kind of structure simple, built-in screw type back of the body stud structure firm, easy to assembly is installed.
For solving the problems of the technologies described above, the utility model provides a kind of built-in screw type back of the body stud structure, and comprise back of the body bolt and push rod screw, the upper end of described back of the body bolt is provided with the thread groove of adaptive push rod screw; The lower end of described back of the body bolt is made up of multiple expanding block, and after push rod screw stretches into back of the body bolt, expanding block is softened; The upper end external surface of described back of the body bolt is provided with detent bumps; Described expanding block external surface is provided with anticreep anti-pulling dovetail bolt; The inner surface of described expanding block is provided with the stop tab preventing push rod screw outstanding.
The utility model improves to be had, and described expanding block is 4, and 4 expanding blocks are equally distributed on back of the body bolt lower end.
The utility model improves to be had, and described detent bumps is monomer, is arranged on the upper end external surface of back of the body bolt.
The beneficial effects of the utility model are: the built-in screw type back of the body bolt manufacture craft of new structure is simple, and cost of production is low; Operation is easy for installation, reduces workflow, increases work efficiency; Dovetail bolt coordinates more closely rationally with entity, and increase firmness further, anticreep tension pull out force is effective.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of built-in screw type back of the body stud structure of the present utility model.
Label declaration: 1-carries on the back bolt; 11-detent bumps; 2-push rod screw; 3-expanding block; 32-anticreep anti-pulling dovetail bolt; 33-stop tab.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
With reference to accompanying drawing 1, the utility model shown in accompanying drawing provides a kind of built-in screw type back of the body stud structure, comprises back of the body bolt 1 and push rod screw 2; The upper end of described back of the body bolt 1 is provided with the thread groove of adaptive push rod screw 2; The lower end of described back of the body bolt 1 is made up of multiple expanding block 3, and after push rod screw 2 stretches into back of the body bolt 1, expanding block 3 is softened; The upper end external surface of described back of the body bolt 1 is provided with detent bumps 11; Described expanding block 3 external surface is provided with anticreep anti-pulling dovetail bolt 32, and the inner surface of described expanding block 3 is provided with the stop tab 33 preventing push rod screw 2 outstanding.
By the setting of detent bumps 11, make push rod screw 2 when rotated, back of the body bolt 1 can not along with sliding together.
In use, by the precession forward of push rod screw 2, expanding block 3 takes advantage of a situation outer and in anticreep anti-pulling dovetail bolt 32 is stuck in dovetail slotted eye that entity opens to the expanding block 3 being arranged on back of the body bolt 1 lower end; The medial surface of expanding block 3 is provided with stop tab 33, and stop tab 33 limits the position of push rod screw 2, prevents push rod screw 2 from rotating excessive and destroying entity through back of the body bolt 1.
In the present embodiment, described expanding block 3 is 4, and 4 expanding blocks 3 are equally distributed on back of the body bolt 1 lower end.
By equally distributed expanding block 3, make whole built-in screw type back of the body bolt stress balance, increase firmness.
In the present embodiment, the material of described back of the body bolt nut 1 and push rod screw 2 is carbon steel or stainless steel, adds the intensity of whole device.
Back of the body bolt nut 1 in the present embodiment can be stamped to form by punching die, simple and compact for structure.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (2)
