TECHNICAL FIELD

[0001] The utility model relates to the field of heating equipment, concretely relates to an inner plating film type quartz heating tube wiring electrode and a conductive structure comprising the same. BACKGROUND

[0002] The inner plating film type quartz heating tube is one type of quartz heating tube, which means that a heating film is plated on the inner side wall of the tube body, and the heating film is powered to generate heat to heat the medium. The plating layer has a silk screen electrode, which needs to be connected to the silk screen electrode through the wiring electrode to supply power to the plating layer.

[0003] At present, the common wiring electrode is mainly made of a material with good electrical conductivity, which is bent and processed into a ring structure matching the specification and shape of the heating tube, and is tightly attached to the silk screen electrode, and then a lead wire is drawn out from the wiring electrode for power supply. However, during the heating process of the heating tube, the wiring electrode is often deformed, or the wiring electrode and the silk screen electrode are not well attached, which causes the plating layer to burn out at the electrode junction when a large instantaneous current passes through, making the heating tube ineffective and posing a safety hazard. SUMMARY

[0004] To overcome the shortcomings of the prior art, the utility model aims to provide an inner plating film type quartz heating tube wiring electrode, which can solve the problem of easy deformation or poor attachment of the wiring electrode of the existing inner plating film type quartz heating tube.

[0005] The utility model realizes the following technical solutions:

[0006] An inner plating film type quartz heating tube wiring electrode comprises: electrode pads, at least one of which has a circular arc contact surface adapted to attach to a silk screen electrode; a first insulating seat abutting against the circular arc contact surface of one of the electrode pads; a second insulating seat abutting against the circular arc contact surface of another of the electrode pads; the first and second insulating seats are arranged opposite to each other so that the two electrode pads face away from each other; and an elastic member, the ends of which abut against the first and second insulating seats respectively, to push the electrode pad on the first insulating seat and the electrode pad on the second insulating seat in opposite directions.

[0007] Further, the inner plating film type quartz heating tube wiring electrode further comprises: an insulating seat fixing screw and an insulating seat fixing nut; the insulating seat fixing screw is simultaneously provided on the first insulating seat, the elastic member and the second insulating seat, and is screwed to the insulating seat fixing nut, so that the elastic member is in a compressed state.

[0008] Further, the first insulating seat and the second insulating seat are respectively provided with a first accommodating groove and a second accommodating groove.

[0009] Further, the first insulating seat is in T-shaped structure, which comprises an electrode mounting part extending in vertical direction and outer wing parts horizontally extending along two sides of the electrode mounting part; the circular arc contact surface of the electrode contact piece is tightly pressed on the end surface of the electrode mounting part, and the first accommodating groove is recessed in the outer wing part; the second insulating seat is in T-shaped structure, which comprises an electrode mounting part extending in vertical direction and outer wing parts horizontally extending along two sides of the electrode mounting part; the circular arc contact surface of the electrode contact piece is tightly pressed on the end surface of the electrode mounting part, and the second accommodating groove is recessed in the outer wing part.

[0010] Further, the electrode contact piece is in L-shaped structure, which comprises the circular arc contact surface abutting on the electrode mounting part and a fastening surface fixedly mounted on the side surface of the electrode mounting part by a fixing bolt.

[0011] Further, the number of the elastic pieces is two, and the elastic pieces are respectively arranged in the two outer wing parts of the first insulating seat and the second insulating seat.

[0012] Further, the first insulating seat and the second insulating seat are made of ceramic or bakelite.

[0013] Further, the elastic piece is a high-temperature-resistant spring.

[0014] Further, the electrode contact piece is a copper piece.

[0015] A conductive structure comprising the inner-plating film type quartz heating pipe wiring electrode, further comprising: a quartz heating pipe; the inner side wall of the quartz heating pipe is provided with a plating film layer, and the plating film layer is provided with a ring-shaped silk screen electrode; the circular arc contact surface of the electrode contact piece is matched with the silk screen electrode and is suitable for abutting on each other; the electrode contact piece on the first insulating seat and the electrode contact piece on the second insulating seat are simultaneously tightly abutted on the silk screen electrode under the action of the elastic piece.

[0016] Compared with the prior art, the utility model can achieve the following effects:

[0017] The first insulating seat and the second insulating seat are respectively provided with an electrode contact piece, and the elastic piece is arranged between the first insulating seat and the second insulating seat; after the wiring electrode is installed in the interior of the quartz heating pipe, the two insulating seats compress the elastic piece, the elastic piece pushes the first insulating seat and the second insulating seat to opposite directions through the reset action, so that the electrode contact pieces on the two insulating seats are tightly pressed on the silk screen electrode, and the electrode contact pieces are led out of the quartz heating pipe through wires to realize power supply.

[0018] Compared to the previous method of manually bending the electrode contacts to make them as close as possible to the shape (curvature) of the screen-printed electrode, this invention first uses the end support structure of the insulating base to maintain the arc shape of the electrode contacts without deformation, ensuring that the electrode contacts always accurately match the curvature of the screen-printed electrode. Simultaneously, the internal elastic element's reset action ensures that the two electrode contacts are always tightly adhered to the screen-printed electrode under elastic force. The two insulating bases also form a stable support structure inside the tube. Thus, the electrode contacts and the screen-printed electrode maintain close contact and are not prone to slippage, and the electrode contacts are not easily deformed. This completely eliminates the problem of poor electrode fit, ensuring a stable power supply to the quartz heating tube and significantly improving reliability. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] This utility model discloses an internally coated quartz heating tube wiring electrode, which is used in conjunction with a quartz heating tube.

[0031] See Figures 1-4 This type of wiring electrode includes: two electrode contacts 10, a first insulating base 20, a second insulating base 30, and an elastic element 40. Each electrode contact 10 includes at least one arcuate contact surface 11 suitable for attaching to a screen-printed electrode 81. The first insulating base 20 abuts against the arcuate contact surface 11 of one electrode contact 10, and the second insulating base 30 abuts against the arcuate contact surface 11 of the other electrode contact 10. The first insulating base 20 and the second insulating base 30 are arranged opposite to each other, so that the two electrode contacts 10 are in a positional relationship of mutual separation. The two ends of the elastic element 40 abut against the first insulating base 20 and the second insulating base 30 respectively, thereby pushing the electrode contacts 10 on the first insulating base 20 and the electrode contacts 10 on the second insulating base 30 away in opposite directions.

[0032] The working principle of this utility model is as follows:

[0033] An electrode contact 10 is abutted on the first insulating seat 20 and the second insulating seat 30 respectively. An elastic element 40 is provided between the first insulating seat 20 and the second insulating seat 30. After the electrode is installed inside the quartz heating tube, the two insulating seats compress the elastic element 40 together. The elastic element 40 pushes the first insulating seat 20 and the second insulating seat 30 in opposite directions through the reset action, thereby pressing the electrode contact 10 on the two insulating seats tightly against the screen printing electrode 81. The electrode contact 10 is then led out of the quartz heating tube through a wire to realize the power supply.

[0034] Compared to the previous method of manually bending the electrode contact 10 to make it as close as possible to the shape (curvature) of the screen-printed electrode 81, this invention first uses the end support structure of the insulating base to maintain the arc shape of the electrode contact 10 without deformation, ensuring that the electrode contact 10 always accurately matches the curvature of the screen-printed electrode 81. Simultaneously, the internal elastic element 40, through its restoring action, ensures that the two electrode contacts 10 are always tightly adhered to the screen-printed electrode 81 under elastic force. The two insulating bases also form a stable support structure inside the tube. Thus, the electrode contact 10 and the screen-printed electrode 81 maintain close contact and are not prone to slippage, and the electrode contact 10 is not easily deformed. This completely eliminates the problem of poor electrode fit, ensuring a stable power supply to the quartz heating tube 80 and significantly improving reliability.

[0035] Preferably, the present invention further includes an insulating base fixing screw 50 and an insulating base fixing nut 60 for adjusting the width of the wiring electrode; the insulating base fixing screw 50 is simultaneously inserted into the first insulating base 20, the elastic member 40 and the second insulating base 30, and screwed to the insulating base fixing nut 60, thereby putting the elastic member 40 in a compressed state.

[0036] Before use, adjust the distance between the first insulating seat 20 and the second insulating seat 30 by tightening the insulating seat fixing screw 50, so that the size of the wiring electrode is close to the internal size of the corresponding quartz heating tube 80, thus facilitating the placement of the wiring electrode inside the quartz heating tube 80. In this way, the wiring electrode can be used with quartz heating tubes 80 of different sizes.

[0037] To ensure stable installation of the elastic element 40 and improve the overall structural compactness of the wiring electrodes, preferably, refer to... Figure 4 The first insulating seat 20 and the second insulating seat 30 are respectively provided with a first receiving groove 21 and a second receiving groove 22, and the two ends of the same elastic member 40 are respectively provided in the first receiving groove 21 and the second receiving groove 22.

[0039] Similarly, the second insulating base 30 has a T-shaped structure, which includes an electrode mounting portion 23 extending vertically and outer wings 24 extending horizontally outward on both sides of the electrode mounting portion 23; the arcuate contact surface 11 of the electrode contact piece 10 is pressed against the end face of the electrode mounting portion 23, and the first receiving groove 21 is recessed in the outer wing 24.

[0040] Preferably, see Figure 5 In order to ensure a stable connection between the electrode contact 10 and the insulating base, the electrode contact 10 is made into an L-shaped structure, which includes an arc contact surface 11 that fits on the electrode mounting part 23, and a fastening surface 12 that is perpendicular to the arc contact surface 11. The fastening surface 12 is fixed to the side of the electrode mounting part 23 by a fixing bolt 70.

[0041] Preferably, two elastic elements 40 are provided, and they are respectively disposed in the two outer wings 24 of the first insulating seat 20 and the second insulating seat 30. By releasing elastic potential energy simultaneously through the elastic elements 40 on both sides, and in conjunction with the T-shaped structure of the insulating seat itself, the direction of the force applied to the electrode contact 10 is always consistent, thereby achieving a stable force application effect.

[0042] Preferably, the first insulating base 20 and the second insulating base 30 are made of ceramic or bakelite material. Of course, other insulating materials known in the art can also be used.

[0043] Preferably, the elastic element 40 is a high-temperature resistant spring, which can withstand the high-temperature heat generated during electrical conduction.

[0044] Preferably, the electrode contact 10 is made of copper, but other known excellent conductive materials in the field can also be used.

[0045] See Figure 6 This utility model also discloses a conductive structure, including the aforementioned inner-coated quartz heating tube wiring electrode, and a quartz heating tube 80. The inner wall of the quartz heating tube 80 has a coating layer, on which an annular screen-printed electrode 81 is provided; the arcuate contact surface 11 of the electrode contact piece 10 matches the screen-printed electrode 81 and is suitable for mutual contact; the electrode contact piece 10 on the first insulating seat 20 and the electrode contact piece 10 on the second insulating seat 30 are simultaneously and tightly attached to the screen-printed electrode 81 by the elastic element 40, thereby providing power to the coating layer (i.e., the heating film) and enabling the quartz heating tube 80 to heat stably.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
