Description

Technical Field

[0001] This utility model relates to the field of communication interface technology, specifically a communication interface device applied to a 1.4G broadband trunking private network repeater. Background Technology

[0002] With the rapid development of wireless communication technology, 1.4G broadband trunking private networks have been widely used in industries such as public safety, transportation, and energy. Repeaters, as important equipment in 1.4G broadband trunking private networks, are mainly used to expand signal coverage and improve network quality.

[0003] However, there are currently some problems with the communication interface between repeaters and other devices in the broadband private network. Traditional communication interfaces, such as... Figure 1 As shown, a flexible lever is provided at the top of the interface. However, traditional levers are made of plastic. Due to the interface being exposed to high temperatures for extended periods, the plastic lever is prone to brittleness, leading to breakage during use. This, in turn, prevents the communication interface from disconnecting promptly when needed, severely impacting the performance and reliability of the entire private network. Therefore, those skilled in the art have provided a communication interface device for a 1.4G broadband trunking private network repeater to address the problems mentioned in the background. Utility Model Content

This device solves the problem that traditional plastic levers are prone to brittleness due to prolonged exposure to high temperatures, leading to breakage during use. Consequently, the communication interface cannot be disconnected promptly when needed, severely impacting the performance and reliability of the entire private network.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a communication interface device applied to a .G broadband trunking private network repeater, comprising a housing, a limiting sleeve installed on the top of the housing, a sliding groove formed on one side of the inner wall of the limiting sleeve, a limiting groove formed on the other side of the inner wall of the limiting sleeve, through holes formed on both sides of the limiting groove, an L-shaped locking block and a pressing rod provided inside the limiting sleeve, a slider installed on the side of the pressing rod facing the sliding groove, a limiting bolt installed on the side of the L-shaped locking block facing the limiting groove, limiting rods installed on both sides of the limiting bolt, and a compression spring provided inside the limiting groove.

[0008] Preferably, the extrusion rod is slidably engaged with the slide groove via a slider.

[0009] Preferably, the limiting bolt is inserted into the limiting groove for limiting, one end of the compression spring is in compression contact with the inner wall of one end of the limiting groove, and the other end of the compression spring is in compression contact with the end of the limiting bolt.

[0010] Preferably, the limiting rod is slidably inserted into the through hole.

[0011] Preferably, the end of the extrusion rod adjacent to the L-shaped block is beveled to facilitate mutual extrusion and contact between the two.

[0012] Preferably, the L-shaped locking block is adapted to the L-shaped slot reserved on the equipment interface. Under the push of the pressing rod, the L-shaped locking block can move along the axial direction of the limiting groove to achieve the locking and fixing of the side of the L-shaped locking block with the protrusion with the slot above the equipment interface. After the pushing action of the pressing rod is released, the L-shaped locking block can return to the initial position under the elastic force of the pressing spring.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a communication interface device for a 1.4G broadband trunking private network repeater, which has the following beneficial effects:

[0015] Through design, the internal communication interface of this utility model includes a housing with a limiting sleeve installed on the top. Inside the limiting sleeve are an L-shaped locking block and a pressing rod. After the signal output end of the housing is plugged into the device, the L-shaped locking block initially inserts into the L-shaped slot reserved in the device interface but does not engage, indicating a preliminary connection. Subsequently, by pushing the pressing rod, the inclined surface of the pressing rod contacts and presses against the inclined surface of the L-shaped locking block. As the pressing spring contracts, the L-shaped locking block moves, allowing the side of the L-shaped locking block with the protrusion to engage with the slot above the device interface. This fixing method is simple and quick. Furthermore, this mechanism for fixing the housing effectively solves the problem of the lever easily breaking during long-term use of traditional communication interfaces, preventing the communication interface from failing to disconnect in time when needed, thus affecting the performance and reliability of the entire private network.

[0023] Please see Figure 2 , Figure 3 and Figure 4 The extrusion rod 3 is slidably engaged with the slide groove 201 via the slider 4. The limiting bolt 502 is limited and inserted into the limiting groove 202. One end of the extrusion spring 6 is in extrusion contact with the inner wall of one end of the limiting groove 202, and the other end of the extrusion spring 6 is in extrusion contact with the end of the limiting bolt 502. The limiting rod 501 is slidably inserted into the through hole 203. The end of the extrusion rod 3 adjacent to the L-shaped locking block 5 is beveled to facilitate mutual extrusion contact. The L-shaped locking block 5 is adapted to the L-shaped slot reserved on the equipment interface. Under the push of the extrusion rod 3, the L-shaped locking block 5 can move axially along the limiting groove 202 to achieve the locking and fixing of the side of the L-shaped locking block 5 with the protrusion with the slot above the equipment interface. After the push of the extrusion rod 3 is released, the L-shaped locking block 5 can return to the initial position under the elastic force of the extrusion spring 6.

[0024] Please see Figure 1 and Figure 2 This mechanism for fixing the outer casing 1 makes it easy to plug and unplug the communication interface, and avoids the problem of the outer casing 1 being difficult to detach from the interface due to the breakage of the lever on the communication interface.

[0025] This utility model's internal communication interface includes a housing 1. A limiting sleeve 2 is installed on the top of the housing 1. A sliding groove 201 is formed on one inner wall of the limiting sleeve 2, and a limiting groove 202 is formed on the opposite side wall of the sliding groove 201. Through holes 203 are formed on both sides of the limiting groove 202. An L-shaped locking block 5 and a pressing rod 3 are provided inside the limiting sleeve 2. A slider 4 is installed on the side of the pressing rod 3 facing the sliding groove 201. The slider 4 is slidably engaged with the sliding groove 201. The L-shaped locking block 5 faces the limiting groove 201. A limit bolt 502 is installed on one side of the groove 202, and limit rods 501 are installed on both sides of the limit bolt 502. The limit rods 501 are slidably inserted into the through hole 203, and the limit bolt 502 is inserted into the limit groove 202 for limiting. A compression spring 6 is provided in the limit groove 202. One end of the compression spring 6 is compressed against one end of the limit groove 202, and the other end is compressed against the limit bolt 502. Under the action of the compression spring 6, the L-shaped locking block 5 is located at the center of the limit sleeve 2.

[0026] When the signal output terminal of the outer casing 1 is plugged into the device, the L-shaped locking block 5 is inserted into the L-shaped slot reserved on the device interface. At this time, the L-shaped locking block 5 is located in the middle of the slot reserved on the device interface and is not engaged with the slot. Then, the pressing rod 3 is pushed into the output terminal side of the casing. After the inclined surface of the pressing rod 3 contacts the inclined surface of the L-shaped locking block 5, the L-shaped locking block 5 is pressed and moved, so that the side of the L-shaped locking block 5 with the protrusion engages with the slot above the device interface, thereby achieving the effect of fixing the outer casing 1. This mechanism for fixing the outer casing 1 makes the communication interface easy to plug and unplug, and avoids the problem of the outer casing 1 being difficult to detach from the interface due to the breakage of the lever on the communication interface.
