Description

Technical Field

[0001] The utility model relates to the technical field of signal isolator debugging equipment, in particular to an improved signal isolator production and debugging tooling. Background Art

[0002] A signal isolator is an electronic device used to electrically isolate input signals from output signals to prevent signal interference and protect equipment. It is commonly used in industrial automation and measurement fields.

[0003] The Chinese patent provides an improved signal isolator production and debugging tooling, with the publication number CN217283943U, including a slide rail, a signal isolator box, a slider movably mounted on the slide rail, and a heat dissipation system on the signal isolator box. The utility model uses a slider to enable the signal isolator box to slide or fix its position along the slide rail, and an elastic card is clamped in a card slot to fix the position of the signal isolator box. By pushing or pulling the signal isolator box, the elastic card is forced to slide out of the card slot to move the signal isolator box to a position, which is convenient for debugging and saves time and effort; the heat dissipation system adopts a method of discharging air from both sides of the air inlet at the bottom of the signal isolator box to improve the heat dissipation effect, and the dustproof net and dustproof cover reduce the dust entering the signal isolator box, which plays a role in fast heat dissipation and dust prevention.

[0004] The signal isolator box in the device can slide along the slide rail or be fixed in position. However, when adjusting the position of the isolator box, it is necessary to push or pull the isolator box with force so that the elastic card can be forced to slide out of the card slot. Due to the resistance of the elastic card, the operator needs to spend a certain amount of pushing or pulling force to fix the signal isolator box, and the practical effect is low. Therefore, it is necessary to provide an improved signal isolator production and debugging tooling. Utility Model Content

[0030] Embodiment 2

[0031] See also Figure 1 , Figure 2 and Figure 3, and on the basis of the first embodiment, it is further obtained that the heat dissipation mechanism 4 includes a heat dissipation fan 404, a mounting groove is opened on the top surface of the signal isolator box 1, a mounting sleeve 401 is fixedly installed on the inner wall of the mounting groove, a dust filter 402 is fixedly installed on the top surface of the mounting sleeve 401, two fixing frames 403 are fixedly installed on the inner wall of the mounting sleeve 401, the heat dissipation fan 404 is fixedly arranged between the two fixing frames 403, air outlets 405 are opened on the left and right sides of the signal isolator box 1, dust covers 406 are arranged on the outer ends of the air outlets 405, and two sets of dust covers 406 are fixedly arranged on the left and right sides of the signal isolator box 1 respectively.

[0032] Furthermore, in this embodiment, the cooling fan 404 arranged in the installation sleeve 401 can cooperate with the air outlets 405 opened at the left and right ends of the signal isolator box 1 to dissipate heat when the signal isolator is working. At the same time, through the setting of the dust filter 402, impurities and dust in the outside air can be effectively prevented from entering the interior of the signal isolator box 1. A dust cover 406 is provided at the air outlet 405, which can effectively prevent dust from entering the interior of the signal isolator box 1 through the air outlet 405.

[0033] In actual operation, the signal isolator housing 1 is installed together with the slide rail 2 at the specified position. When the position of the signal isolator housing 1 needs to be adjusted, the two knobs 312 are pressed inwardly respectively to make the positioning slide bar 310 slide inwardly along the inner wall of the through hole 304, so that the two protrusions on the positioning slide bar 310 can be separated from the limiting hole 309 opened on the inner surface of the slide rail 2, and then the knob 312 is rotated to ninety degrees to make the protrusions on the positioning slide bar 310 rotate from a horizontal state to a vertical state identical to the limiting hole 309, and then the knob 312 is released. At this time, the spring 313 sleeved on the surface of the positioning slide bar 310 is no longer squeezed by external force and begins to release. The elastic force is released, so that the spring 313 pushes the fixed block 311 to drive the positioning slide bar 310 to slide to the outer end. At this time, the protruding block on the positioning slide bar 310 can pass through the limiting hole 309 and be limited at the left end of the moving block 303, and the protruding block end on the positioning slide bar 310 is located in the moving groove 306 and will not affect the movement of the moving block 303 in the slide rail 2. At this time, the positioning slide bar 310 releases the positioning of the signal isolator box 1, and then the signal isolator box 1 can be pushed to adjust the position. When the signal isolator box 1 moves, the roller 305 on the inner wall of the groove at the bottom of the moving block 303 rolls on the inner wall of the slide rail 2, thereby improving the stability of the signal isolator box 1 when it moves;

[0034] After the position of the signal isolator housing 1 is adjusted, the knob 312 is pressed again to make the positioning slide bar 310 slide inward. After the protruding block end of the positioning slide bar 310 extends out of the limiting hole 309, the knob 312 is rotated ninety degrees again to make the protruding block of the positioning slide bar 310 horizontal. Then, the knob 312 is released. Under the rebound of the spring 313, the protruding block of the positioning slide bar 310 is reset and closely attached to the left end of the limiting hole 309, thereby completing the limiting of the moving block 303 and realizing the rapid fixation of the signal isolator housing 1.

[0035] When the signal isolator box 1 is in use, the cooling fan 404 arranged in the mounting sleeve 401 can cooperate with the air outlets 405 opened at the left and right ends of the signal isolator box 1 to dissipate heat when the signal isolator is working. At the same time, the dust filter 402 can be set to effectively prevent impurities and dust in the outside air from entering the interior of the signal isolator box 1. A dust cover 406 is set at the air outlet 405, which can effectively prevent dust from entering the interior of the signal isolator box 1 through the air outlet 405.

[0036] Other parts of the present invention not described in detail belong to the prior art and will not be described here.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
