Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a rail-type industrial switch. Background Art

[0002] Industrial switches are network switching devices designed specifically for industrial environments, used to transmit data within industrial control systems. Unlike standard commercial switches, industrial switches typically offer higher reliability, durability, and interference immunity, making them adaptable to harsh operating environments such as high and low temperatures, humidity, vibration, and electromagnetic interference. Rail-mount industrial switches are designed specifically for industrial environments and utilize DIN rail mounting for easy installation.

[0003] Announcement No. CN220359276U discloses a switch that is easy to install, which includes a mounting base arranged on the switch housing, a mounting groove provided on the mounting base, a card rail is placed in the mounting groove, the card rail abuts against the bottom of the mounting groove, a positioning groove is provided on the groove wall of the mounting groove, one side of the card rail is embedded in the positioning groove, and a control component is provided on the mounting base, which is used to apply thrust to the card rail.

[0004] However, in the above solution, the control lever in the control assembly is arranged on the back of the mounting base, very close to the rail. Since the rail is arranged on the wall or in the control box, when the staff adjusts the control lever, the wall or the control box will cause obstacles to the staff, making it inconvenient to rotate the control lever.

[0005] Therefore, we propose a rail-type industrial switch to solve the above problems. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] A card seat, a fixed card plate and a movable card plate are set on the back of the body. When the body is installed, the vertical plate in the limiting mechanism is provided with an inclined surface, and moves upward when it contacts the card plate on the card rail. When the card plate enters the card slot, the vertical plate and the horizontal plate move downward under the action of the reset mechanism to lock the card plate. In this way, the body can be fixed on the card rail at any position; at the same time, the setting of the positioning mechanism can automatically position the card seat after the rack is installed to prevent it from moving along the extension direction of the card rail.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-5 As shown, the utility model provides a card-rail type industrial switch, comprising a body 1 and a card rail 3 with a U-shaped structure. A card base 2 adapted to the card rail 3 is provided on the back side of the body 1. Card plates 4 extending outward are provided on the upper and lower sides of the card rail 3. A fixed card plate 5 engaged with the lower card plate 4 is provided at the bottom of the card base 2. The fixed card plate 5 has an L-shaped structure, and its top is in contact with the bottom wall of the card rail 3. A positioning mechanism is provided between the fixed card plate 5 and the card rail 3. A movable card plate 6 engaged with the upper card plate 4 is slidably installed on the top of the card base 2.

[0027] like Figure 3 and Figure 4 As shown, the movable card plate 6 includes a limiting mechanism and a reset mechanism. There are multiple reset mechanisms along the extension direction of the card rail 3. The limiting mechanism includes a horizontal plate 61 and a vertical plate 62 arranged on one side of the horizontal plate 61. A handle 7 is provided on the top of the horizontal plate 61. A card slot that is engaged with the upper card plate 4 is formed between the vertical plate 62 and the card base 2. The vertical plate 62 has an inclined surface 63 on one side away from the card base 2. The reset mechanism includes a sliding rod 65 fixed at the bottom of the horizontal plate 61 and an expansion plate 66 arranged at the bottom of the sliding rod 65. A mounting groove 64 that is slidably connected to the sliding rod 65 and the expansion plate 66 is opened on the upper side of the interior of the card base 2, and a reset spring 67 is provided between the top of the expansion plate 66 and the top wall of the mounting groove 64.
