Description
Technical field
The utility model belongs to electric heating element technical field, more particularly to a kind of U-shaped right angle Si-Mo rod.
Background technology
Si-Mo rod is a kind of high temperature resistant being made based on molybdenum disilicide, oxidation resistant resistance heating element.In high temperature
In use, fine and close quartz (SiO2) glass-film of one layer of light of Surface Creation, can protect Si-Mo rod internal layer under oxidizing atmosphere
Do not reoxidize.Under oxidizing atmosphere, maximum operation (service) temperature is 1800 DEG C, and the resistance of Si-Mo rod increases rapidly as temperature is raised
Plus, the resistance value stabilization when temperature-resistant.Existing Si-Mo rod is mainly made up of cold end and heating part, its cold end and heating part one
As be fixedly connected by way of welding, due to Si-Mo rod in high temperature some soften, it is not only hard but also crisp during low temperature, in the mistake used
Once deforming or colliding in journey, Si-Mo rod will be broken, and the heating part of Si-Mo rod is thin and length is easiest to occur to break
Split, after the heating part of Si-Mo rod is broken, it is impossible to change or change difficult, often whole Si-Mo rod can all be discarded, so
Result in the waste of material；And there is stress in the cold end and heating part of Si-Mo rod, can reduce the intensity of Si-Mo rod after welding,
Because cold end and heating part can not be dismantled, therefore space-consuming is big, is stored inconveniently and safeguards.
Utility model content
The utility model in order to solve weak point of the prior art there is provided one kind it is simple in construction, be easy to dismount, be easy to
The U-shaped right angle Si-Mo rod safeguarded and deposited.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：U-shaped right angle Si-Mo rod, including take the shape of the letter U
The heating part of structure and the cold end for being located at heating part two ends, the plane where heating part perpendicular to the plane where two cold ends,
Two cold end lower sides offer mounting groove, and heating part two ends corresponding inserted is in two mounting grooves, two cold end sidepiece edges
The screwed hole being connected with mounting groove radially is offered, heating part two ends sidepiece offers the through hole corresponding with screwed hole, spiral shell
Pit internal thread is connected with countersunk head screw, and countersunk head screw passes through through hole, and heating part two ends outer surface is provided with screw thread and is threadedly coupled
There is locking nut, locking nut holds out against cooperation with cold end sidepiece.
One piece of reinforcing plate is at least fixedly connected between two cold ends.
Two cold end cross sections are square, and heating part is in hollow tubular structure.
Heating part outer surface, which is spaced apart, is provided with heat emission hole.
Using above-mentioned technical proposal, the utility model has the following advantages that：
1st, corresponding inserted is distinguished in two mounting grooves in heating part two ends of the present utility model, and will be sent out using countersunk head screw
Hot portion two ends are fixed in mounting groove, easy to disassemble, while using locking nut by heating part two ends and cold-end locking, it is to avoid hair
Hot portion is come off so that work is more stablized.
2nd, dismountable attachment structure is used between heating part and cold end, after heating part is damaged, only heating part need to be changed
, cold end part can reuse, it is to avoid the waste of material, cost-effective, be easy to safeguard；When storage or transport,
Heating part and cold end can be split so that space-consuming is reduced.
3rd, it is connected with reinforcing plate between two cold ends so that overall intensity increase, work is more stablized；During heating part is in
Hollow tube-like structure, can increase the utilization rate of material.
4th, heating part outer surface is spaced apart the heat being provided with inside heat emission hole, heating part and can given out by heat emission hole
Come, considerably increase radiating efficiency.

Fig. 2 is the structural representation of cold end in Fig. 1；
Fig. 3 is the structural representation of heating part in Fig. 1.
Embodiment
As Figure 1-3, U-shaped right angle Si-Mo rod of the present utility model, including the structure that takes the shape of the letter U heating part 1 and be located at hair
The cold end 2 at the hot two ends of portion 1, the plane where heating part 1 is perpendicular to the plane where two cold ends 2, two lower sides of cold end 2
Offer mounting groove 3, the two ends corresponding inserted of heating part 1 in two mounting grooves 3, two sidepieces of cold end 2 radially offer with
The screwed hole 4 that mounting groove 3 is connected, the two ends sidepiece of heating part 1 is offered in the through hole 5 corresponding with screwed hole 4, screwed hole 4
Countersunk head screw 6 is threaded with, countersunk head screw 6 passes through through hole 5, and the two ends outer surface of heating part 1 is provided with screw thread 7 and is threaded with
Locking nut 8, locking nut 8 holds out against cooperation with the sidepiece of cold end 2.
At least it is fixedly connected between two cold ends 2 in one piece of reinforcing plate, figure and does not illustrate reinforcing plate.
Two cross sections of cold end 2 are square, and heating part 1 is in hollow tubular structure.
The outer surface of heating part 1, which is spaced apart, is provided with heat emission hole 9.
Locking nut 8 when in use, is first screwed in the both ends of heating part 1 by the utility model, then inserts the two ends of heating part 1
It is located in mounting groove 3, and make it that the through hole 5 of the end of heating part 1 is corresponding with the hole 4 of screw thread 7 in cold end 2, using countersunk head screw 6
It is threaded in the hole 4 of screw thread 7 and passes through through hole 5 so that the termination of heating part 1 is fixed in mounting groove 3, tightens locking nut 8,
The loose or dislocation of heating part 1 is avoided, this is placed in behind fixed position using new, two cold ends 2 are led with two electrodes respectively
Logical, electric current produces heat by heating part 1 by resistance.
