Description

Technical Field

[0001] This utility model relates to the field of plasma electrode technology, specifically to an insulating protective sleeve structure for preventing corona discharge in plasma electrodes. Background Technology

[0002] A plasma electrode is an electrode that can generate plasma. The insulating protective sleeve of the plasma electrode is an accessory used in plasma cutting equipment. It is generally made of ceramic or insulating materials. When in use, it is installed at the electrode nozzle of the plasma cutting equipment. Its function is to provide electrical insulation protection and also has the function of preventing corona discharge.

[0003] Traditional corona-proof insulating sleeve structures for plasma electrodes, while installed outside the electrode nozzle for corona protection during use, are inconvenient for dust protection when the nozzle is not in use. External dust falling onto the nozzle can affect its normal operation. Therefore, we propose an improved corona-proof insulating sleeve structure for plasma electrodes to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an insulating protective sleeve structure for anti-corona discharge of plasma electrodes, so as to solve the problem mentioned in the background art that it is inconvenient to protect the electrode nozzle from dust.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating protective sleeve structure for anti-corona discharge of plasma electrodes, comprising an insulating sleeve body, an opening at the bottom of the insulating sleeve body, a connecting bracket fixed at the front end of the insulating sleeve body, a sealing cover installed inside the connecting bracket, a rubber sealing plug installed at one end of the sealing cover, a rubber connecting strip installed at the bottom end of the sealing cover, and one end of the rubber connecting strip fixed to the outer wall of the insulating sleeve body.

[0006] As a further technical solution of this utility model, the cross-section of the rubber sealing plug is smaller than the cross-section of the opening, and the rubber sealing plug and the opening form an engaging structure.

[0007] As a further technical solution of this utility model, the cross-section of the sealing cover is smaller than the cross-section of the connecting card seat, and the sealing cover and the connecting card seat form an engaging structure.

[0008] As a further technical solution of this utility model, a connecting sleeve is installed on the outer side wall of the insulating sleeve body, and a heat-insulating silicone sleeve is installed on the outer side wall of the connecting sleeve, and an anti-slip groove is provided inside the heat-insulating silicone sleeve.

[0009] As a further technical solution of this utility model, the anti-slip groove is provided in a plurality of places, and the plurality of anti-slip grooves are distributed in a ring at equal intervals inside the heat-insulating silicone sleeve.

[0010] As a further technical solution of this utility model, locking holes are provided on both sides of the interior of the insulating sleeve body, and locking bolts are threaded into the interior of each locking hole.

[0011] As a further technical solution of this utility model, the locking bolts are provided in two sets, and the two sets of locking bolts are symmetrically distributed about the central axis of the insulating sleeve body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by setting components such as a sealing cover, a rubber sealing plug, a rubber connecting strip, and a connecting bracket, when the insulating sleeve body is installed on the outside of the electrode nozzle for protection, when the electrode nozzle is not in use, the rubber sealing plug in the above components can also be engaged with the opening at the bottom of the insulating sleeve body to seal the opening, thereby realizing that the insulating sleeve body also has the function of dust protection for the electrode nozzle, with better protection effect and stronger practicality;

[0013] By incorporating components such as anti-slip grooves, heat-insulating silicone sleeves, and connecting sleeves, the insulating sleeve body is installed outside the electrode nozzle for use. The heat-insulating silicone sleeve in these components can insulate the insulating sleeve body from heat, preventing burns caused by people touching the surface of the insulating sleeve body during work. Furthermore, the heat-insulating silicone sleeve in these components has evenly spaced anti-slip grooves inside, which increases the friction between people's hands and the heat-insulating silicone sleeve, making the installation and removal of the heat-insulating silicone sleeve more stable and less prone to slipping.

[0014] With locking bolts and locking holes, the inner wall of the insulating sleeve body is threaded to match the thread on the outside of the electrode nozzle, which is used to install the insulating sleeve body on the outer wall of the electrode nozzle. After the insulating sleeve body is installed on the outer wall of the electrode nozzle, the above-mentioned components can lock the insulating sleeve body from both sides, which greatly increases the stability of the insulating sleeve body on the outer wall of the electrode nozzle and improves the installation effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides an embodiment of an insulating protective sleeve structure for anti-corona discharge of a plasma electrode, comprising an insulating sleeve body 1, an opening 8 at the bottom of the insulating sleeve body 1, a connecting bracket 10 fixed at the front end of the insulating sleeve body 1, a sealing cover 6 installed inside the connecting bracket 10, a rubber sealing plug 7 installed at one end of the sealing cover 6, a rubber connecting strip 9 installed at the bottom end of the sealing cover 6, and one end of the rubber connecting strip 9 fixed to the outer side wall of the insulating sleeve body 1. The cross-section of the rubber sealing plug 7 is smaller than the cross-section of the opening 8, and the rubber sealing plug 7 and the opening 8 form a locking structure, which provides a better sealing effect for the opening 8. The cross-section of the sealing cover 6 is smaller than the cross-section of the connecting bracket 10, and the sealing cover 6 and the connecting bracket 10 form a locking structure. The locking structure design facilitates the storage of the sealing cover 6, and because of the design of the rubber connecting strip 9, the sealing cover 6 is not easily lost.

[0022] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when the insulating sleeve body 1 is installed on the outer wall of the electrode nozzle for protection, when the electrode nozzle is no longer in use, the sealing cover 6 can be pulled out from the inside of the connecting bracket 10, and then the rubber sealing plug 7 at one end of the sealing cover 6 can be inserted into the opening 8 at the bottom of the insulating sleeve body 1 to seal the opening 8 and prevent external dust from falling onto the electrode nozzle. When the electrode nozzle needs to be used normally, the rubber sealing plug 7 can be taken out from the opening 8 and aligned with the connecting bracket 10 to lock together, and the opening 8 can be opened to store the sealing cover 6.

[0023] A connecting sleeve 5 is installed on the outer wall of the insulating sleeve body 1, and a heat-insulating silicone sleeve 4 is installed on the outer wall of the connecting sleeve 5. The heat-insulating silicone sleeve 4 has an anti-slip groove 2 inside. There are several anti-slip grooves 2, and the several anti-slip grooves 2 are distributed in a ring at equal intervals inside the heat-insulating silicone sleeve 4, so that the anti-slip effect of the insulating sleeve body 1 is better.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, after the heat-insulating silicone sleeve 4 is installed on the outer wall of the insulating sleeve body 1, it not only achieves heat insulation protection, but also allows people to contact the outer wall of the heat-insulating silicone sleeve 4 when they twist the insulating sleeve body 1. The anti-slip grooves 2, which are evenly distributed, effectively increase the friction between people's hands and the insulating sleeve body 1, making it less slippery when disassembling and installing the insulating sleeve body 1.

[0025] Locking holes 11 are provided on both sides inside the insulating sleeve body 1, and locking bolts 3 are threaded inside the locking holes 11. There are two sets of locking bolts 3, and the two sets of locking bolts 3 are symmetrically distributed about the central axis of the insulating sleeve body 1, which makes the locking of the insulating sleeve body 1 more secure.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the insulating sleeve body 1 is installed on the outer wall of the electrode nozzle through the internal threads and the threads on the outer wall of the electrode nozzle. Then, two sets of locking bolts 3 are taken and rotated in sequence into the connecting brackets 10 on both sides inside the insulating sleeve body 1 and screwed into place to squeeze the electrode nozzle, so that the insulating sleeve body 1 is stably installed on the outer wall of the electrode nozzle.

[0027] Working principle: In use, take out the insulating sleeve body 1 and install it on the outside of the electrode nozzle. During installation, the insulating sleeve body 1 is installed on the outer wall of the electrode nozzle through the internal threads and the threads of the outer wall of the electrode nozzle. After installation, take out two sets of locking bolts 3 and rotate them in sequence into the connecting brackets 10 on both sides inside the insulating sleeve body 1 and tighten them into place to squeeze the electrode nozzle, thereby reinforcing the installation of the insulating sleeve body 1 on the outer wall of the electrode nozzle. After reinforcement, it can protect the electrode nozzle during use and prevent the generation of corona. After the electrode nozzle is used, the sealing cover 6 can be pulled out from the inside of the connecting bracket 10, and then the rubber sealing plug 7 at one end of the sealing cover 6 can be inserted into the opening 8 at the bottom of the insulating sleeve body 1 to seal the opening 8 and prevent external dust from falling into the electrode nozzle.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
