This novel heat preservation mounting is including the bolt that adopts macromolecular material preparation, the bolt includes the head, and the one end of head is coaxial to be provided with hollow screw rod, and the internal perisporium of screw rod is provided with the conical surface that contracts gradually to the head, and the end of conical surface is provided with the internal thread, and the outer peripheral face of screw rod is provided with the external screw thread, and the bolt has the nut through threaded connection. The utility model provides an easy problem that appears the heat preservation leak, influence the heat preservation effect when adopting metal bolt as the mounting of heated board.

Description

Novel heat preservation mounting

Technical Field

The utility model belongs to the technical field of auto-parts and specifically relates to a novel heat preservation mounting is related to.

Background

At present when installing heat preservation type decorative wall, generally earlier with the pre-buried wall body that advances of common ordinary bolt of purchase on the market, hang the heated board on the double-screw bolt that stretches out the wall body again, reuse nut fastens the two as an organic wholely, however ordinary bolt on the market generally adopts the metal material preparation, and the metal heat conductivity is strong, leads to the heated board to appear the heat preservation leak, influences the heat preservation effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a to the not enough of prior art existence, provide one kind and adopt the polymer material preparation, avoid the heated board novel heat preservation mounting that the heat preservation leak appears.

In order to achieve the above object, the utility model discloses technical scheme that the heat preservation mounting adopted is:

the utility model provides a novel heat preservation mounting, includes the bolt that adopts macromolecular material to make, the bolt includes the head, and the one end of head is coaxial to be provided with hollow screw rod, and the internal perisporium of screw rod is provided with the conical surface that contracts gradually to the head, and the end of conical surface is provided with the internal thread, and the outer peripheral face of screw rod is provided with the external screw thread, and the bolt has the nut through threaded connection. The heat conductivity of the high polymer material is poor relative to the heat conductivity of the metal material, the heat conductivity of the bolt is further reduced by the hollow screw, and the screw is internally connected with a cone matched with the conical surface through internal threads so as to ensure the strength of the tail end of the screw and ensure the tightness of the connection of the bolt and a wall body.

Preferably, the polymer material is PA 66.

Preferably, the head is circular, square or hexagonal in shape.

Preferably, the nut is a hexagonal nut or a square nut.

Compared with the prior art, the utility model, have following advantage:

the bolt that adopts PA66 preparation is poor for the bolt heat conductivity of metal material preparation, and the well hollow portion of bolt further reduces the heat conductivity of bolt, and the screw rod is inside through the toper thing that internal thread connection and conical surface match to guarantee the terminal intensity of screw rod, guarantee bolt and wall connection's compactness simultaneously, hang the heated board on this bolt, with the fixed back of hexagon nut, avoid the heated board heat preservation leak to appear, ensure the heat preservation effect.

Drawings

FIG. 1 is a schematic structural view of a novel heat-insulating fixing member;

FIG. 2 is a front view of a novel insulating fixture;

fig. 3 is a cross-sectional view of fig. 2.

The bolt comprises a bolt 1, a head 11, a screw 12, a conical surface 121, an internal thread 122, an external thread 123 and a nut 2.

Detailed Description

The present invention will be further clarified by the following description in conjunction with the accompanying drawings, which are to be understood as illustrative only and not as limiting the scope of the invention, and modifications of the various equivalent forms of the invention by those skilled in the art after reading the present invention are within the scope defined by the appended claims.

As shown in fig. 1-3, including the bolt 1 made of the high polymer material, the high polymer material is PA66, the bolt includes a head 11, the head shape is circular, a hollow screw 12 is coaxially arranged at one end of the head, the head and the screw are integrally injection-molded, a tapered surface 121 which gradually shrinks towards the head is arranged on the inner peripheral wall of the screw, an internal thread 122 is arranged at the tail end of the tapered surface, an external thread 123 is arranged on the outer peripheral surface of the screw, the bolt is connected with a nut 2 through the external thread, and the nut is a hexagon nut.

The specific working process and principle of the novel heat-preservation fixing piece are as follows: the bolt is embedded in the wall body, the heat insulation plate is suspended on the stud extending out of the wall body and fixed through the hexagon nut, and then the conical body matched with the conical surface is fixed inside the stud through the internal thread, so that the strength of the screw and the tightness of the screw connected with the wall body are guaranteed. The utility model discloses a PA66 preparation bolt that thermal conductivity is poor designs into hollow structure with the screw rod again, reduces the heat transfer, further reduces the thermal conductivity of bolt to avoid the heat preservation leak that appears on the heated board, ensure the heat preservation effect.
