Abstract

The utility model discloses a novel whole-body bolt, comprising a bolt body; the two ends of the bolt body are respectively provided with bolt heads with threads; a T-shaped limiting bump extends out of the end part of one bolt head; the bolt body between the two bolt heads is provided with a plurality of cylindrical platforms with the diameter of the section of larger than that of the bolt body at intervals; and the bolt heads and the cylindrical platform at the side are connected by arc-shaped transition. As the structure is adopted, the novel whole-body bolt has the following advantages that 1. the T-shaped limiting bump can be inserted into a die hole suitable for the die plate so as to play a role in limiting; and 2. the tensile strength is large, bending is not easy to occur when in use, the service life is long and the production cost is greatly reduced.

Description

A kind of novel entire body bolt

Technical field

The utility model relates to the bolt technical field, particularly a kind of novel 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 mould that difficulty is installed.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.

The model utility content

Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of pull resistance strong, convenient fixing, spacing novel entire body bolt.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of novel 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, 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 by 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 by arc-shaped transition respectively.

The utility model adopts said structure, and have 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 the drawings and specific embodiments the utility model is described in further detail;

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is connected cross section structure schematic representation on the bolt head for spacing block set in the utility model;

In Fig. 1～Fig. 2,1, the body of bolt; 2, bolt head; 3, spacing block set; 4, cylinder table.

Embodiment

As Fig. 1～a kind of novel 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, the end of one of them bolt head is extended with T-shape spacing block set 3, according to concrete needs, have nib in template, 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 by arc-shaped transition between the cylinder table 4 of described bolt head 2 and its side, increased pull resistance greatly, and the radius of a circle at the arc place of this arc-shaped transition is 10～18cm.The both sides of cylinder table 4 are connected on the body of bolt by 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.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.

Claims
