Detailed Description

The present invention will be described in further detail with reference to examples.

Example 1:

the cutting board stud of this embodiment is as shown in fig. 1-3, including connecting portion 1, the left and right sides of connecting portion 1 is equipped with left bolt portion 3 and right bolt portion 4 respectively, integrated into one piece has cutting board portion 2 on the bottom surface of connecting portion 1, wherein, the left side and the 3 integrated into one piece of left bolt portion of connecting portion 1, right mounting hole 5 that is used for installing right bolt portion 4 is seted up on the right side of connecting portion 1, set up the right slotted hole 7 of arranging along the left-right direction of connecting portion 1 on the lateral wall of both sides around right mounting hole 5, set up right through-hole on right bolt portion 4, be equipped with the right connecting rod 9 of wearing out right slotted hole 7 in the right through-hole, the both ends threaded connection that right slotted hole 7 was worn out to right connecting rod 9.

When the tool plate double-head bolt is used, the tool plate part 2 can be directly inserted or clamped into a high-temperature outlet to be sealed, the left and right bolt parts 4 are connected with an external connecting part, when the distance between the bolt part on the right side and the connecting part is insufficient, the right fastening nut 11 is loosened, the right fastening nut 11 is screwed after the right bolt part 4 is pulled out, the problem is solved by adjusting the length of the tool plate double-head bolt, and when the distance between the left bolt part 3 and the connecting part is insufficient, the tool plate double-head bolt can be installed in a direction changing manner (namely rotated by 180 degrees).

Cutting board portion 2 in this embodiment is square, connecting portion 1 is arc, cutting board portion 2 of square structure is convenient for insert the high temperature mouth and plays the effect of sealing, connecting portion 1 of circular arc structure carries out a good transition between cutting board portion 2 to the bolt portion of cutting board bolt, the preparation of conveniently processing, circular arc structure has also prolonged the route of heat transfer simultaneously, all kinds of holes on connecting portion 1 have also increased the heat dissipation, thereby the at utmost has prolonged the high temperature deformation cycle of cutting board bolt, guarantee cutting board portion 2 seal the effect. Further, the junction of connecting portion 1 and cutting board portion 2 outwards bulges and forms annular limiting plate 12, annular limiting plate 12 makes each part structure of cutting board bolt clear on the one hand, the upper portion of annular limiting plate 12 is connecting portion 1 promptly, the lower part is cutting board portion 2, on the other hand, because annular limiting plate 12 protrusion in cutting board portion 2, when making cutting board portion 2 insert the high temperature export, annular limiting plate 12 can cover the clearance department at high temperature export and cutting board portion 2, guarantee the effect of sealing, in addition, annular limiting plate 12 and left and right bolt portion 4 still leave the clearance, when guaranteeing that right bolt portion 4 adjusts, the lateral wall of high temperature export can not appear the contact between with right bolt portion 4.

Embodiment 1 is only fit for being used for one side and connects the condition when the distance is not enough to can lead to the asymmetry of cutting board stud structure after the bolt adjustment of one side, after the cutting board bolt atress, can produce the moment of torsion, cause the damage to cutting board stud.

Example 2:

as shown in fig. 4 and 5, the principle of the present embodiment is similar to that of embodiment 1, except that a left mounting hole for mounting the left bolt portion 3 is formed in the left side of the connecting portion 1 of the present embodiment, left oblong holes 6 arranged along the left-right direction of the connecting portion 1 are formed in the side walls of the front and rear sides of the left mounting hole, a left through hole is formed in the left bolt portion 3, a left connecting rod 8 penetrating through the left oblong hole 6 is arranged in the left through hole, and two ends of the left connecting rod 8 penetrating through the left oblong hole 6 are connected with left fastening nuts 10 through threads. With the above arrangement, the left and right bolt portions 4 of the present embodiment are both adjustable in the left-right direction, and the adjustment length of the blade stud bolt is further increased as compared with embodiment 1.

In addition, the contact surface between the connection portion 1 and the left and right fastening nuts 11 of the present embodiment is provided with an anti-slip layer for increasing the friction force between the fastening nuts and the connection portion 1, because the connection portion 1 is configured to be an arc-shaped structure, the contact surface between the fastening nuts and the connection portion 1 has to be reduced, and by adding the anti-slip layer, the loss of connection strength caused by the reduction of the contact surface can be compensated to a certain extent.

Further, the left and right bolt portion 4 of this embodiment is equipped with scale 13, guarantee left and right bolt portion 4 and external connection part can be stably connected under the circumstances, through reading scale 13, can guarantee about the length that bolt portion 4 was adjusted can be the same, can make about setting that bolt portion 4 can be symmetrical in the both sides of cutting board portion 2 like this, this kind of symmetrical structure is favorable to the homogeneity of kinetic energy transmission, avoid this cutting board stud to produce torsion because of both sides moment is inhomogeneous, thereby cause the influence to cutting board stud's life.

The above-mentioned embodiments are merely illustrative of the inventive concept and are not intended to limit the scope of the invention, which is defined by the claims and the insubstantial modifications of the inventive concept can be made without departing from the scope of the invention.
