The disassembly process is simpler and more convenient than using bolts.

Description

Technical Field

[0001] This utility model relates to the field of chemical electrical technology, and in particular to quick connection and protection components for chemical electrical circuits. Background Technology

[0002] In the chemical production field, electrical circuits serve as the core power and control transmission carrier for equipment operation. Their connection stability and protection safety directly affect the continuous operation of the production system and the life safety of operators. Chemical workshops are often characterized by high humidity, corrosive gases, and high dust concentrations. There is also a risk of loosening of wiring connections due to equipment vibration and temperature changes. Once the sealing of electrical circuit connections fails or poor contact occurs, it can easily lead to leakage, short circuits, or even sparks, potentially causing serious safety accidents such as fires, explosions, or equipment shutdowns.

[0003] However, existing quick-connect and protection components for chemical electrical circuits have the following drawbacks:

[0004] (1) Traditional sealing structures rely on bolt fastening. After long-term use, the bolts are prone to loosening due to vibration. Moreover, during disassembly and maintenance, the bolts need to be removed one by one, which is time-consuming and laborious. In case of emergency, it is difficult to deal with hidden dangers quickly.

[0005] (2) Core connection components such as wiring terminals are mostly fixed installations. When a fault occurs and replacement is needed, a large number of fixed structures need to be disassembled, which not only prolongs the maintenance time, but may also damage the surrounding lines due to improper operation during the disassembly process.

[0006] Therefore, this utility model provides a quick connection and protection component for chemical electrical circuits. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The technical problem solved by this utility model is to provide a highly practical, simple, and easily operable chemical electrical circuit quick connection and protection component. This solves the problems mentioned in the background art, where traditional sealing structures rely heavily on bolt fastening, which are prone to loosening due to vibration after long-term use. Furthermore, disassembly and maintenance require removing each bolt individually, which is time-consuming and labor-intensive. In emergencies, it is difficult to quickly handle potential hazards. Core connection components such as wiring terminals are mostly fixed installations, which require the disassembly of a large number of fixed structures when a fault occurs and replacement is needed. This not only prolongs maintenance time but may also damage surrounding circuits due to improper operation during disassembly.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick connection and protection component for chemical electrical circuits, including a mounting box, wherein a sealing component is provided at the upper end of the mounting box, and a disassembly component is provided on the inner wall of the mounting box;

[0011] A sealing assembly, comprising a retaining plate, a first insert rod, a limiting frame, a fixing spring, a limiting rod, and a sealing cover, wherein the retaining plate is movably connected to the inner wall of the upper end of the mounting box, the first insert rod is fixedly installed at the upper end of the retaining plate, the limiting frame is fixedly installed at the middle of the surface of the first insert rod, and the limiting rod is fixedly installed on one side of the upper end of the first insert rod;

[0012] The disassembly assembly includes a mounting block, a pressure plate, a locking block, a slide rod, a locking spring, and a terminal block body. The mounting block is fixedly installed on the inner wall of the mounting box. A pressure plate is movably connected to one side of the mounting block, and a locking block is movably connected to one side of the pressure plate. A slide rod is inserted into one end of the locking block.

[0013] Optionally, a sealing cover is slidably connected to the surface of the limiting frame, and a limiting groove is sequentially formed at the upper end of the sealing cover. The limiting groove facilitates the control of the rotation angle of the first insertion rod in conjunction with the limiting rod.

[0014] Optionally, a fixing spring is sleeved on the upper end of the surface of the first insertion rod. The upper end of the fixing spring is fixedly installed on the inner top wall of the sealing cover. The fixing spring facilitates the pulling of the card plate out of the insertion hole.

[0015] Optionally, a snap-fit ​​spring is sleeved on the surface of the slide rod, one end of the snap-fit ​​spring is fixedly installed on one side of the locking block, and a terminal body is fixedly installed on one side of the slide rod. The snap-fit ​​spring facilitates the locking of the locking block to one side of the pressure plate.

[0016] Optionally, mounting rods are fixedly installed on both sides of the mounting box, and a fixing sleeve is threaded to one end of each mounting rod. The fixing sleeve facilitates the fixing of the cable.

[0017] Optionally, the upper end of the mounting box is provided with insertion holes in sequence, and a locking rod is fixedly installed on one side of the locking plate in sequence. The inner wall of the insertion hole is provided with a locking groove that matches the locking rod. The locking rod is designed to cooperate with and fix the spring to be locked into the locking groove.

[0018] (III) Beneficial Effects

[0019] This utility model provides a quick connection and protection component for chemical electrical circuits, which has the following beneficial effects:

[0020] 1. This quick-connect and protection component for chemical electrical circuits, through the setting of the sealing component, allows for the following: When in use, pressing down the first insert rod sequentially drives the limiting frame, thereby stretching the fixing spring. At the same time, the locking rod is pushed out of the slot. Then, the first insert rod is rotated, and the rotation angle is determined by the limiting rod. After releasing the first insert rod, the fixing spring drives the locking plate to slide out of the insertion hole, allowing the sealing cover to be removed for maintenance. The disassembly steps are simpler and more convenient than those for bolts.

[0021] 2. This quick-connect and protection component for chemical electrical circuits, through its disassembly mechanism, allows for easy removal of the terminal block if a malfunction affects its use. Pressing the pressure plate causes the locking block to slide on the slide rod, simultaneously compressing the locking spring and retracting the locking block into the terminal block. This allows the terminal block to be removed and, after replacement, prevents it from moving around inside the mounting box and causing physical damage. The fixing sleeve is then installed, further increasing the stability of the cable. Attached Figure Description

At the same time, the retaining rod 6 is pushed out of the retaining groove. Then, the first insert rod 202 is rotated and the rotation angle is determined by the limiting rod 205. Then, the first insert rod 202 is released and the fixing spring 204 drives the retaining plate 201 to slide out of the insertion hole, so that the sealing cover 206 can be removed for maintenance. The disassembly steps are simpler and more convenient than bolts.

[0030] The disassembly assembly 3 includes a mounting block 301, a pressure plate 302, a locking block 303, a slide bar 304, a locking spring 305, and a terminal block body 306. The mounting block 301 is fixedly installed on the inner wall of the mounting box 1.

One end of the locking block 303 is inserted into the slide bar 304. By setting up the disassembly assembly 3, if the terminal block body 306 malfunctions and affects its use, pressing the pressure plate 302 will cause the locking block 303 to slide on the slide bar 304, while compressing the locking spring 306 and retracting the locking block 303 into the terminal block body 306, thereby allowing the terminal block body 306 to be removed. Then, the fixing sleeve 5 can be installed to further increase the stability of the cable.

[0031] A sealing cover 206 is slidably connected to the surface of the limiting frame 203. A limiting groove is sequentially opened at the upper end of the sealing cover 206. The limiting groove facilitates the control of the rotation angle of the first insertion rod 202 in conjunction with the limiting rod 206.

[0032] A fixing spring 204 is sleeved on the upper end of the surface of the first insertion rod 202. The fixing spring 204 facilitates the pulling of the card plate 201 out of the insertion hole. The upper end of the fixing spring 204 is fixedly installed on the inner top wall of the sealing cover 206.

[0033] A snap-fit ​​spring 305 is sleeved on the surface of the slide rod 304. The snap-fit ​​spring 305 facilitates snapping the snap-fit ​​block 303 onto one side of the pressure plate 302. One end of the snap-fit ​​spring 305 is fixedly installed on one side of the snap-fit ​​block 303. A terminal block body 306 is fixedly installed on one side of the slide rod 304.

[0034] Mounting rods 4 are fixedly installed on both sides of mounting box 1. One end of mounting rod 4 is threadedly connected to a fixing sleeve 5. The fixing sleeve 5 facilitates the fixing of cables.

The inner wall of the insertion hole has a series of card slots that are compatible with the card rod 6.

[0036] In this invention, the working steps of the device are as follows:

[0037] First step: When using, press down on the first insert rod 202 to drive the limiting frame 203, thereby stretching and fixing the spring 204. At the same time, slide the locking rod 6 out of the slot. Then rotate the first insert rod 202 and determine the rotation angle through the limiting rod 205. Then release the first insert rod 202 and fix the spring 204 to drive the locking plate 201 out of the insertion hole to remove the sealing cover 206. Then maintenance can be performed. The disassembly steps are simpler and more convenient than bolts.

[0038] Second step: Finally, if the terminal block body 306 malfunctions and affects its use, press down the pressure plate 302 to drive the locking block 303 to slide on the slide bar 304, and at the same time compress the locking spring 306 to retract the locking block 303 into the terminal block body 306, so that the terminal block body 306 can be removed, and then the fixing sleeve 5 can be installed to further increase the stability of the cable.
