Abstract
The utility model particularly relates to a combined pressing-type leading-out rod of a heating body, which is applied to the field of industrial furnace and electric heating equipment. The combined pressing-type leading-out rod is characterized by comprising a leading-out rod and a line-pressing device, wherein the line-pressing device comprises a hollow line-pressing pipe which is internally provided with an arc-shaped line-pressing plate; the line-pressing pipe is provided with a line-pressing bolt; and the outer end of the leading-out rod is connected together with the inner end of the line-pressing pipe. The combined pressing-type leading-out rod solves the defects of inconvenient line connection and unsafe use of the leading-out rod in the prior art, and has the advantages of convenient use, safety, reliability and long service life.
Description
Technical field
The utility model is specifically related to a kind of heater combination compression joint type eduction rod that is applied to industrial furnace and electroheat equipment field thereof.
Technical background
Industrial furnace and firing equipment thereof mainly rely on the heating element in its burner hearth that heat energy is provided, after heating element is installed in the burner hearth, the termination cooling need be drawn and carried out the transition on the Temperature-controlled appliance with the live wire well compressed, heating element belongs to the high temperature heater, needing material with identical material to increase its sectional area several times from the burner hearth spill process implements cooling and can be connected with electric wire, above-mentioned object is referred to as eduction rod, the length of eduction rod is by the thickness decision of furnace wall, general all greater than 0.5 meter, termination with eduction rod and heating element during electric furnace manufacturer sell goods welds together, external cabling needs user oneself to connect, the user generally selects to adopt wire cable clamp or the special-purpose wire clamp of electric wire that electric wire and eduction rod are linked together, because the sectional area of eduction rod is much larger than electric wire, contact-making surface is little between electric wire and the eduction rod, contact site resistance is big, sparking easily takes place, simultaneously because heating is big, easily electric wire or eduction rod are burnt out, the replacing eduction rod is wasted time and energy, and influences the normal use of electric furnace.For security consideration, the user need be installed a protective cover at the eduction rod place additional toward contact, prevents that the staff from getting an electric shock and scald.
The utility model content
The purpose of this utility model is to solve prior art eduction rod wiring inconvenience, uses unsafe defective, and a kind of heater esy to use, safe and reliable combination compression joint type eduction rod is provided.
The utility model is achieved by the following technical solution:
It is a kind of heater combination compression joint type eduction rod, it is characterized in that comprising eduction rod and cord grip, cord grip comprises the line ball pipe of hollow, and line ball pipe inside is provided with the arc tension disc, the line ball pipe is provided with the line ball bolt, and the inner of the outer end of eduction rod and line ball pipe links together.
The eduction rod outer cover is equipped with the insulating ceramics pipe.The insulating ceramics pipe wraps up eduction rod, can prevent that the user of service from getting an electric shock.
Line ball pipe outer cover is equipped with the bakelite safty shield, and the outer end of bakelite safty shield is provided with entrance hole.The bakelite safty shield wraps up cord grip, can prevent that the user of service from getting an electric shock.
The bakelite safty shield is provided with metal nuts outward, between bakelite safty shield and the metal nuts by being threaded.When metal nuts can be installed in furnace wall in advance, after line ball finishes, bakelite safty shield rotation is installed on the metal nuts gets final product.
The inner of eduction rod is provided with the wiring welding groove.Adopt above-mentioned setting, exit and the eduction rod of being convenient to heating element weld together.
Operation principle of the present utility model is as follows:
Eduction rod is installed in the furnace wall together with the insulating ceramics pipe, the terminals of heating element are inserted in the wiring welding groove of eduction rod the inner and weld together, electric wire passes the entrance hole of bakelite safty shield, insert line ball pipe inside, utilize hold-down bolt with electric wire and the tight pressing of arc tension disc, the electric wire fixation, simultaneously because hold-down bolt, the line ball pipe, the arc tension disc is metallic article, electric conductivity is good, also increased contact area, reduced resistance, after wiring finishes, bakelite safty shield rotation is installed on the metal nuts that is installed in advance on the furnace wall, can wraps up cord grip is whole, prevent that the user of service from touching cord grip and causing electric shock.
The utlity model has advantage esy to use, safe and reliable, long service life.Adopt specialized cord grip, increased contact area, reduced resistance, broken off relations the defective that causes sparking because of loose contact or contact area very little easily; Bakelite safty shield and insulating ceramics pipe wrap up cord grip and eduction rod respectively, can prevent that the user of service from touching cord grip and causing electric shock.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
A among Fig. 2 Fig. 1 is to view.
As shown in FIG.: 1 eduction rod; 2 insulating ceramics pipes; 3 metal nuts; 4 arc tension discs; 5 hold-down bolts; 6 line ball pipes; 7 bakelite safty shields; 8 entrance holes; 9 wiring welding grooves.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1 and Figure 2: eduction rod 1 outer cover is equipped with insulating ceramics pipe 2, eduction rod 1 left end is provided with wiring welding groove 9, right-hand member is connected with cord grip, cord grip comprises the line ball pipe 6 of hollow, line ball pipe 6 is provided with two hold-down bolts 5, inside is provided with arc tension disc 4, and the cord grip outer cover is equipped with bakelite safty shield 7, and the outer end of bakelite safty shield 7 is provided with entrance hole 8.
When the utility model uses, eduction rod 1 is installed in the furnace wall together with insulating ceramics pipe 2, the terminals of heating element are inserted in the wiring welding groove 9 of eduction rod 1 left end and weld together, electric wire passes the entrance hole 8 of bakelite safty shield 7, insert line ball pipe 6 inside, utilize two hold-down bolts 5 with electric wire and the 4 tight pressings of arc tension disc, the electric wire fixation, simultaneously because hold-down bolt 5, line ball pipe 6, arc tension disc 4 is metallic article, electric conductivity is good, also increased contact area, reduced resistance, after wiring finishes, 7 rotations of bakelite safty shield have been installed on the metal nuts 3 that is installed in advance on the furnace wall, can wrap up cord grip is whole, prevent that the user of service from touching cord grip and causing electric shock.
