Abstract

The utility model provides a combined element of an electric heating piece, which mainly lies in that a bolt which can be positioned and have no idle running is arranged in the conductive hole of the electric heating piece, thread and a positioning hole are arranged on the positioning bolt, when being provided for positioning a spiraling screw cap, the positioning hole can be inserted into, to ensure the bolt do not perform idle running when spiraling screw cap, thereby, the easier and more convenient combined element of the electric heating piece can be achieved.

Description

The binding member of electric heating piece

Technical field

The utility model relates to a kind of binding member of electric heating piece, be meant the bolt on the conductive hole of being located at electric heating piece especially, this bolt is provided with location hole and allows when screwing togather nut, can be with the location hole location of positioning body by the end, allow the thing that does not have bolt idle running when screwing togather nut take place, and then provide more convenient spiral shell to establish the binding member of electric heating piece.

Background technology

Electric heating piece 1 (extremely shown in Figure 2) according to prior art as Fig. 1, it mainly is to establish into bolt 11 on the conductive hole 10 on the electric heating piece 1, on bolt 11, be inserted in metal washer 12 and nut 13 again, only this bolt 11 is because of limited space, so bolt 11 heads 110 are located in the electric heating piece 1, and spigot 111 is passed on the conductive hole 10 of electric heating piece 1, be inserted in metal washer 12 again and be screwed into nut 13 location, yet nut 13 is in the idle running that screws togather often because of bolt 11, it is very difficult that nut 13 spiral shells are established, the top that former need are often clamped bolt 11 with clip, again nut 13 is screwed tight the location, yet destroyed the top of bolt 11 also,, still had its inconvenience in the use so in the time will changing element, nut 13 can't be screwed out.

The utility model content

Main purpose of the present utility model: providing a kind of can be located with the positioning body engaging by the conductive hole inner bolt of electric heating piece, and it is more convenient and easy to allow positioning screw cap screw togather.

For realizing above-mentioned purpose, the technical scheme that the utility model adopted is: the end of this threaded portion is provided with location hole.

Wherein location hole is arranged with in the threaded portion, so can not destroy the integrality of screw thread.

Wherein location hole can be hexagon ring, cross bore, a word hole, square opening etc., can plug the location for positioning body.

The beneficial effect that adopts technique scheme to bring is:

1, bolt 2 of the present utility model can allow metal washer 12 that electric heating piece 1 is more tight with contacting of conducting element, so can allow the electric heating piece 1 heating and continuous thing that does not have the outage that gets loose take place.

2, the location hole 22 on the bolt 2 of the present utility model, available positioning body N locatees and allows bolt 2 not slide, and then it is more easy that nut 13 is screwed tight.

Embodiment

Relevant the utility model in order to achieve the above object, effect, the technological means of being used is now enumerated preferred embodiment and conjunction with figs., details are as follows:

At first, please refer to Fig. 3 to shown in Figure 8, the utility model embodiment is the bolt 2 that is used for electric heating piece 1, this bolt 2 includes head 20, screw thread 21 and location hole 22, wherein location hole 22 is located at bolt 2 screw threads 21 ends, and this location hole 22 can be hexagon ring, cross bore, a word hole ... ... etc.

During use, earlier bolt 2 is penetrated in the conductive hole 10 of electric heating piece 1, and make screw thread 21 pass electric heating piece 1, be inserted in metal washer 12 at bolt 2 again, be screwed into nut 13 subsequently on the screw thread 21 of bolt 2, when nut 13 produces slip idle running with bolt 2, only need positioning body N can be inserted location hole 22, make bolt 2 located by positioning body N, so, can be easily with nut 13 close positioning on electric heating piece 1.

Above-mentionedly method of the present utility model, feature and combination relevant position are done a detailed description, more distinguished for making the purpose of this utility model, feature and effect, below now its effect, advantage of using situation and expection to reach is described as follows:

1. bolt 2 of the present utility model can allow metal washer 12 that electric heating piece 1 is more tight with contacting of conducting element, so can allow the electric heating piece 1 heating and continuous thing that does not have the outage that gets loose take place.

2. the location hole 22 on the bolt 2 of the present utility model, available positioning body N are located and are allowed bolt 2 not slide, and then it is more easy that nut 13 is screwed tight.

Only with above-mentioned person, it only is a preferred embodiment of the present utility model, when not limiting practical range of the present utility model with this, be that all equalizations of being done according to the utility model claim and utility model description change or modify, all should still belong in the scope that the utility model patent contains.
