Abstract
The invention discloses a through bolt. The through bolt comprises a bolt body, wherein both sides of the bolt body are provided with a bolt head with threads respectively; the end of one bolt head extends a T-shaped limiting lug; the bolt body between the two bolt heads is provided with a plurality of cylindrical stands of which the diameter of each section is greater than that of the bolt body at intervals; and the bolt heads are connected with the lateral cylindrical stands through a curved transition. Because of the structure, the through bolt has the following advantages that: 1, the T-shaped limiting lug can be inserted into the adaptive die hole of a template to play the action of limiting; and 2, the tensile strength is large, the through bolt is difficult to curve when used, the service life is long, and the production cost is greatly reduced.
Description
Technical field
The present invention relates to the bolt technical field, particularly a kind of entire body bolt.
Background technique
At present, in the production process of mould, need to use the entire body bolt to connect, and common entire body bolt only plays fixing effect in use, and template is not played spacing effect, cause the mould difficult installation.Simultaneously, this entire body bolt torque is little, pull resistance is poor, and crooked easily, causes the entire body bolt shorter working life like this, increases cost, causes waste.
Summary of the invention
Technical problem to be solved by this invention is to the deficiency of existing technology, to provide a kind of pull resistance strong, convenient fixing, spacing entire body bolt.
For solving the problems of the technologies described above; Technological scheme of the present invention is: a kind of entire body bolt; Comprise the body of bolt, the two ends of the described body of bolt are respectively equipped with the threaded shank head, and the end of one of them bolt head is extended with the T-shape spacing block set; The compartment of terrain is provided with the cylinder table of a plurality of diameter of sections greater than the body of bolt on the body of bolt between described two bolt heads, is connected through arc-shaped transition between the cylinder table of described bolt head and its side.
The both sides of described cylinder table are connected on the body of bolt through arc-shaped transition respectively.
The present invention adopts said structure, has the following advantages: 1, the T-shape spacing block set can insert in the nib that adapts of template, plays spacing effect; 2, pull resistance intensity is big, and not flexible during use, long service life greatly reduces cost of production.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation;
Fig. 1 is a structural representation of the present invention;
Fig. 2 is connected the cross section structure schematic representation on the bolt head for spacing block set among the present invention;
In Fig. 1～Fig. 2,1, the body of bolt; 2, bolt head; 3, spacing block set; 4, cylinder table.
Embodiment
Like Fig. 1～a kind of entire body bolt shown in Figure 2; Comprise the body of bolt 1, the two ends of the body of bolt 1 are respectively equipped with threaded shank 2, and the end of one of them bolt head is extended with T-shape spacing block set 3; According to concrete needs; In template, have nib, the T-shape spacing block set can insert in the nib that adapts of template, plays spacing effect.
The compartment of terrain is provided with the cylinder table 4 of a plurality of diameter of sections greater than the body of bolt on the body of bolt between two bolt heads 2; Be connected through arc-shaped transition between the cylinder table 4 of described bolt head 1 and its side; Increased pull resistance greatly, and the radius of a circle at the arc of this arc-shaped transition place is 10～18cm.The both sides of cylinder table 4 are connected on the body of bolt through arc-shaped transition respectively, have increased its pull resistance greatly, and the radius of a circle at the arc place of this arc-shaped transition is 36～46cm, with the 40cm best results.
In sum, the whole pull resistance intensity of entire body bolt is big, and is not flexible during use, improved integral intensity, performance.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted method design of the present invention and technological scheme to carry out; Or directly apply to other occasion without improvement, all within protection scope of the present invention.
Claims (2)
