Description

Technical Field

[0001] This utility model relates to the field of wireless communication, and in particular to a portable node device. Background Technology

[0002] Node devices are a core concept in network communication, distributed systems, the Internet of Things (IoT), and computer technology. They refer to physical or logical units within a system that perform specific functions and interact with other devices or nodes. Their core role is to enable the coordination and expansion of system functions through connectivity, communication, or data processing.

[0003] Currently, due to breakthroughs in computer technology, some monitoring activities that require wide-area and high-density coverage often need to carry more node devices in order to achieve the desired effect. For example, in forest fire prevention, it is necessary to deploy a LoRaWAN temperature and humidity node every 10-20 square kilometers.

[0004] Existing node devices are often moved to designated locations manually. However, when multiple node devices need to be placed in the same area, in order to save time and because the node devices themselves are not heavy, staff often move multiple devices at once. However, when the node devices are stacked high, the devices at the top are prone to falling during the handling process, resulting in damage during transportation. Therefore, a portable node device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable node device, which aims to improve the problem that the node device at the top is prone to falling off when carrying multiple node devices at the same time in the prior art.

[0032] 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.

[0033] Reference Figures 1-3This utility model provides an embodiment of a portable node device, including a housing 1, which serves as the outer shell of the node device. The housing 1 contains a circuit board, wiring ports, and other components. A placement groove 2 is formed at the top of the housing 1. The placement groove 2 is rectangular in shape and contains a rotating block 3. Both ends of the rotating block 3 are rounded, and the length of the rotating block 3 is shorter than the width of the placement groove 2. Two rotating blocks 3 are provided, and their ends are fixedly connected by a connecting rod 4. The distance between the connecting rod 4 and the center of the rotating block 3 near the middle of the housing 1 is less than half the depth of the placement groove 2. That is, when the rotating block 3 is vertical, the height of the connecting rod 4 is lower than the height of the upper surface of the housing 1. A carrying rope 5 is fixedly connected to the ends of the two rotating blocks 3. The carrying rope 5 is non-elastic. The carrying rope 5 ensures that when a worker is carrying a small number of node devices at the same time, the node device can be carried by hand using the carrying rope 5.

[0034] Reference Figures 2-4 A fixing mechanism 6 is provided on the outside of the rotating block 3 and inside the housing 1. The fixing mechanism 6 includes a pneumatic pipe 61, which is located in the middle of the housing 1 in the front-rear direction and on the outside of the placement slot 2 in the left-right direction. The outer wall of the pneumatic pipe 61 is penetrating and fixedly connected to the inner wall of the housing 1. A rotating sleeve 62 is fixedly connected to one end of the pneumatic pipe 61 near the middle of the housing 1. The rotating sleeve 62 is tubular in shape. A rotating tube 63 is rotatably connected to the inner wall of the rotating sleeve 62. The rotating tube 63 is tubular in shape, and its outer wall is connected to the rotating sleeve. The inner wall of 62 is made of rubber, and the outer wall of the rotating tube 63 is in contact with the inner wall of the rotating sleeve 62. The end of the rotating tube 63 away from the air pressure tube 61 is fixedly connected to the end of the rotating block 3 away from the middle of the housing 1. The interior of the air pressure tube 61 is in communication with the interior of the rotating block 3. A piston plate 64 is slidably connected to the inner wall of the air pressure tube 61. The bottom end of the piston plate 64 is elastically connected to the inner wall of the air pressure tube 61 by a spring. The outer wall of the piston plate 64 is in contact with the inner wall of the air pressure tube 61, and the piston plate 64 can move up and down while maintaining contact with the inner wall of the air pressure tube 61.

[0035] Reference Figure 3 , Figure 4 and Figure 6A pressure block 65 is fixedly connected to the top of the piston plate 64. A sliding chamber 66 is provided on the inner wall of the rotating block 3. The interior of the sliding chamber 66 is connected to the interior of the rotating block 3. A piston plate 67 is piston-connected to the inner wall of the sliding chamber 66. The outer wall of the piston plate 67 is in contact with the inner wall of the sliding chamber 66. A locking block 68 is fixedly connected to the end of the piston plate 67 away from the middle of the rotating block 3. An inclined chamfer is provided at the upper end of the locking block 68 away from the middle of the rotating block 3. A slot 69 is provided at the bottom of the housing 1. A slot 610 is provided on the inner wall of the housing 1 outside the slot 69. The shape of the slot 610 matches the shape of the locking block 68. When the top of the vertical housing 1 of one rotating block 3 is in contact with the bottom of the other housing 1, the locking block 68 inside the rotating block 3 is exactly at the same height as the slot 610 of the other housing 1. The slot 69 is in contact with the slot 610.

[0036] Reference Figure 2 , Figure 5 and Figure 6 The housing 1 is internally equipped with a reset assembly 7, which includes a slide groove 71. The slide groove 71 is rectangular in shape. A threaded rod 72 is rotatably connected to the inner wall of the slide groove 71. The front end of the threaded rod 72 penetrates the inner wall of the housing 1, and the front end of the threaded rod 72 has a protrusion with anti-slip texture on its edge. A sliding plate 73 is threadedly connected to the outer wall of the threaded rod 72. The sliding plate 73 slides back and forth relative to the slide groove 71. A reset rod 74 is fixedly connected to the rear end of the sliding plate 73. The reset rod 74 is at the same horizontal position as the slot 610. The rear end is provided with an inclined chamfer, and the length of the reset rod 74 on the side closer to the middle of the slot 69 is shorter than that on the side farther from the middle of the slot 69. By setting the inclined chamfer, it is ensured that the chamfer can push the locking block 68 to reset it. The outer wall of the reset rod 74 is slidably connected to the inner wall of the housing 1. An arc-shaped block 8 is fixedly connected to one end of the air pressure pipe 61 near the rotating block 3. A stop block 9 is fixedly connected to the outer wall of the rotating block 3. The stop block 9 is set in the recess of the arc-shaped block 8. When the stop block 9 rotates from one side of the recessed position of the arc-shaped block 8 to the other side, the stop block 9 rotates exactly ninety degrees.

[0037] Working principle: When using the device, if it is necessary to carry a lot of node equipment, the operator first rotates the rotating block 3 placed on the upper part of the housing 1 below to a vertical position. Since the stop block 9 will rotate synchronously with the rotating block 3 when it rotates, the stop block 9 can rotate to a position that just contacts the outer wall of the concave position of the arc-shaped block 8 after the rotating block 3 rotates to a vertical position.

[0038] After the rotating block 3 is in a vertical position, the staff places other node devices on the top of the housing 1 and aligns the slot 69 at the bottom of the housing 1 with the rotating block 3.

[0039] When the rotating block 3 enters the housing 1, the locking block 68 is exactly in the area inside the slot 69. At this time, the housing 1 of the upper node device continues to move downward. When it moves to the bottom of the upper housing 1 and contacts the top of the pressure block 65, it continues to move. At this time, the pressure block 65 is under pressure, which drives the piston plate 64 to move downward. Therefore, the gas inside the air pressure pipe 61 passes through the groove inside the rotating block 3 under pressure and then enters the sliding chamber 66. This causes the piston plate 67 to have an outward force. However, since the outer wall of the locking block 68 is blocked by the outer wall of the slot 69, the locking block 68 cannot move until the top of the lower housing 1 is in contact with the bottom of the upper housing 1. At this time, the slot 610 is exactly flush with the locking block 68, so the locking block 68 enters the interior of the slot 610.

[0040] Once multiple node devices are fixed in the above manner, when staff move them together, the node devices at the top are less likely to fall because they are fixed to the node devices below.

[0041] Once the device is transported to the appropriate position, the operator rotates the threaded rod 72. Because the slide plate 73 is limited by the inner wall of the slide groove 71, the slide plate 73 cannot rotate with the rotation of the threaded rod 72. Therefore, the slide plate 73 slides backward and drives the reset rod 74 to move backward.

[0042] After the reset rod 74 moves backward to contact the locking block 68, since the reset rod 74 is rigid and the gas is compressible, the locking block 68 has room to move. Therefore, it enters the sliding chamber 66 under the push of the inclined surface of the reset rod 74. At this time, the operator can achieve the separation effect of the two node devices by moving the upper shell 1 upward.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
