It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Example 1:

referring to fig. 1-2, the embodiment of the application provides a high temperature resistant screw, which includes a screw body 1, a high temperature resistant layer 14 is provided on the outer surface of the screw body 1, the screw body 1 includes a nut 15, an upper screw rod 4 fixedly connected to the nut 15, and a lower screw rod 6 connected to the other end of the upper screw rod 4, and a connection screw rod 5 is detachably provided between the upper screw rod 4 and the lower screw rod 6 through a limiting component. The high temperature resistant layer 14 enables the screw body 1 to obtain high temperature resistance, and the screw body is not easy to loosen when used in a high temperature environment. Through setting up connecting screw 5, be convenient for prolong the length of screw body 1, improved the practicality.

The high temperature resistant layer 14 is made of an inorganic high temperature resistant material, so that the screw body 1 obtains high temperature resistance.

The screw body 1 is further provided with a mounting block 7, and the other end of the mounting block 7 is connected with an elastic ring 8. The elastic ring 8 is arranged, so that the anti-loosening performance of the screw body 1 is improved.

The top of the nut 15 is provided with a gap 2, and the gap 2 is provided with a protective rubber sleeve 3. The setting of protection gum cover 3 can let the lifting surface area increase of nut 15, also can let the lifting surface area increase of screw body 1 when revolving the brick, helps avoiding screw body 1 to avoid the atress too big for screw body 1 has the risk of twisting off.

Spacing subassembly is including setting up in the slot 9 at last screw rod 4 bottom and 6 tops of lower screw rod, is equipped with the inserted block 10 of pegging graft in slot 9 on connecting screw rod 5, has all seted up mounting groove 11 on the wall of inserted block 10 left and right sides, has all run through on the wall of slot 9 left and right sides and has seted up trompil 13, and the opening part of mounting groove 11 runs through and is equipped with the gag lever post 16 of pegging graft in trompil 13, fixedly between gag lever post 16 and the 11 inside walls of mounting groove being equipped with spacing spring 12.
