Description
Technical Field
[0001] The present invention relates to the technical field of electrical instruments and meters, in particular to an outdoor electrical instrument and meter with good protection performance. Background Art
[0002] Electrical instruments are used to measure, monitor, and analyze electrical signals and related physical quantities. They include ammeters, voltmeters, and wattmeters for measuring current, voltage, and power. Multimeters can measure a variety of electrical parameters. Oscilloscopes can display electrical signal waveforms. Frequency meters are used to measure frequency, etc. Most of them are based on electrical principles such as electromagnetic induction and Ohm's law, converting the measured electrical quantity into intuitive forms such as pointer deflection and digital display. They are widely used in the production, commissioning, and maintenance of the power, electronics, and electrical industries, as well as in scientific research and teaching. They are important tools for ensuring the normal operation of electrical equipment and circuit analysis. The patent application with publication number CN220820141U discloses an outdoor electrical instrument with good protective performance, including an instrument body, and protective components are provided at both ends of the instrument body, the protective components include two connecting plates, and protective rods distributed in a circular array, and the two connecting plates are respectively provided on both sides of the instrument body; the utility model provides protective rods and connecting plates on the outdoor electrical instrument, and by rotating the protective rods on the connecting plates, the protective rods form a cylindrical mesh cover to cover the ends of the electrical instrument. When the electrical instrument is hit or accidentally falls to the ground, its mesh cover will first contact the impact object or the ground, thereby utilizing the protective rods on the mesh cover to offset most of the impact, thereby preventing the outdoor electrical instrument inside from being directly impacted, and thereby effectively improving the protective capability of the outdoor electrical instrument. The above patent provides a protective rod and a connection plate on the outdoor electrical instrument. By rotating the protective rods on the connection plate, the electrical instrument can be damaged by collision caused by falling during use. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the present invention provides an outdoor electrical instrument with good protection performance to solve the problems raised in the above background technology.
[0004] To achieve the above object, the present invention is implemented through the following technical solutions: an outdoor electrical instrument with good protection performance, including electrical components, the electrical components are set to work outdoors; A mounting hole is provided on the top plane of the electrical component, and the mounting hole is a circular through hole that passes through the top and bottom planes of the electrical component; A plate having a size larger than that of the electrical component and a weight greater than that of the electrical component is fixedly connected to the bottom plane of the electrical component by welding; Also includes a buffer mechanism: The buffer mechanism includes a parachute, a first spring, a base, an extrusion rod and an air bag; The airbag in the buffer mechanism is located at the bottom of the electrical component and is tightly fixed to the bottom plane of the electrical component by strong glue, and there is a gap of a certain width between the airbag and the edge of the mounting hole. The buffer mechanism effectively reduces the impact force when the electrical component falls, and greatly reduces the risk of damage to electrical instruments and meters due to collision. When the electrical component falls, the airflow flows through the mounting hole, lifting the parachute. The parachute and the airflow collide with each other, slowing down the falling speed and initially playing a buffering role. At the same time, the parachute rises and pulls the first spring, and pulls the base and the extrusion rod through the first spring. The extrusion rod squeezes the airbag, and the raised position on one side of the airbag further bulges under the action of the airflow, and is cushioned under the plate at the bottom of the electrical component, buffering again. The multiple buffers greatly reduce the impact force of landing.
[0005] Preferably, the parachute is arranged above the top of the mounting hole and is connected to the base and the extrusion rod through the first spring. One end of the first spring is fixedly connected to the bottom center of the parachute, and the other end is connected to the top center of the base.
[0006] Preferably, a guiding mechanism is further included, which includes a motor, a rotating shaft, a first bearing, a belt and a support assembly. The motor in the guiding mechanism is installed on one side inside the electrical component, and the output end of the motor is connected to one end of the rotating shaft. The rotating shaft is rotatably installed on the bracket inside the electrical component through the first bearing, and the rotating shaft is connected to the first bearing through the belt.
[0007] Preferably, the supporting assembly in the guide mechanism includes a protruding block, an extrusion block, a second spring, a second bearing, an elastic rod, and a third bearing. The protruding block is fixedly mounted on the outer wall of the first bearing, one end of the second spring is connected to the second bearing, and the other end is connected to the extrusion block, and the elastic rod is connected to the first bearing through the third bearing.
[0008] Preferably, a control switch is provided at the bottom center of the parachute, and the control switch is electrically connected to the motor through an electric wire for controlling the start-up of the motor.
[0009] Preferably, during the rotation of the first bearing, the centrifugal force thereof will cause the elastic rod to overcome the pulling force of the second spring and extend. During the extension process, the elastic rod pulls the second spring through the second bearing. The setting of the guiding mechanism can guide the direction of the bumping of the electrical component after landing, thereby preventing damage to internal instruments and meters due to irregular rolling and bumping when landing. When the parachute pulls the first spring to start the motor, the motor drives the rotating shaft, belt and first bearing to rotate, causing the elastic rod to extend and collide with the ground under the action of centrifugal force. After the elastic rod rotates and contacts the ground, it drives the electrical component to move, guiding its bumping direction, ensuring that the electrical component lands more smoothly.
[0010] Preferably, the extrusion block can be clamped on the protrusion block under the extrusion action of the second spring, so that the elastic rod is buffered by the elasticity of the second spring.
[0011] Preferably, after the elastic rod rotates and contacts the ground, it will drive the electrical component to move in a certain direction, thereby guiding the direction of the bumping of the electrical component after it falls to the ground.
[0012] The present invention provides an outdoor electrical instrument with good protection performance. It has the following beneficial effects: 1. This outdoor electrical instrument with good protective performance effectively reduces the impact force when the electrical components fall through the buffer mechanism, greatly reducing the risk of damage to the electrical instruments and meters due to collision. When the electrical components fall, the airflow flows through the mounting hole, lifting the parachute. The parachute and the airflow collide with each other, slowing down the falling speed and playing a preliminary buffering role. At the same time, the parachute rises and pulls the first spring, and the first spring pulls the base and the extrusion rod. The extrusion rod squeezes the airbag. The raised position on one side of the airbag further bulges under the action of the airflow, cushioning under the plate at the bottom of the electrical component, providing further buffering. The multiple buffers greatly reduce the impact force of landing.
[0013] 2. The outdoor electrical instrument with good protective performance can guide the direction of the bumping of the electrical components after landing through the setting of the guiding mechanism, thereby preventing the internal instruments and meters from being damaged due to irregular rolling and bumping when landing. When the parachute pulls the first spring to start the motor, the motor drives the rotating shaft, belt and first bearing to rotate, causing the elastic rod to extend and hit the ground under the action of centrifugal force. After the elastic rod rotates and contacts the ground, it drives the electrical components to move, guiding their bumping direction, ensuring that the electrical components land more smoothly.
[0014] 3. This outdoor electrical instrument with good protective performance sets a plate with a size and weight larger than the electrical component at the bottom, so that the electrical component will be in a stable state of falling bottom when it falls, providing a stable foundation for the buffer mechanism and guide mechanism to play a role.

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.
[0019] For example 1, please refer to Figure 1-5 , the present invention provides a technical solution: an outdoor electrical instrument with good protection performance, comprising an electrical component 1, the electrical component 1 is set to work outdoors; A mounting hole 2 is provided on the top plane of the electrical component 1. The mounting hole 2 is a circular through hole that passes through the top and bottom planes of the electrical component 1. A plate having a size larger than the electrical component 1 and a weight greater than the electrical component 1 is fixedly connected to the bottom plane of the electrical component 1 by welding; Also includes a buffer mechanism 3: The buffer mechanism 3 includes a parachute 31, a first spring 32, a base 33, an extrusion rod 34 and an air bag 35; The airbag 35 in the buffer mechanism 3 is located at the bottom of the electrical component 1 and is tightly fixed to the bottom plane of the electrical component 1 by strong glue, and a gap of a certain width exists between the airbag 35 and the edge of the mounting hole 2 .
[0020] The parachute 31 is arranged above the top of the mounting hole 2 and is connected to the base 33 and the extrusion rod 34 through a first spring 32. One end of the first spring 32 is fixedly connected to the bottom center of the parachute 31, and the other end is connected to the top center of the base 33.
[0021] The electrical component 1 is set up outdoors to work; The electrical component 1 is provided with a mounting hole 2. When the electrical component 1 is dropped, air will flow through the mounting hole 2. A plate larger than the electrical component 1 is provided at the bottom of the electrical component 1. Therefore, the plate weighs more than the electrical component 1, causing the electrical component 1 to appear to be falling. The buffer mechanism 3 includes a parachute 31, a first spring 32, a base 33, an extrusion rod 34 and an air bag 35; The airbag 35 is fixed to the bottom of the electrical component 1, and a gap exists between the airbag 35 and the mounting hole 2. Therefore, when the airflow passes through the mounting hole 2, the airflow pushes up the parachute 31. The rising of the parachute 31 pulls up the first spring 32, causing the parachute 31 to leak out from the top of the mounting hole 2. The umbrella-shaped configuration of the parachute 31 can then collide with the airflow, slowing the falling speed of the electrical component 1. When the parachute 31 is buffered by the airflow, the parachute 31 pulls the base 33 and the extrusion rod 34 through the first spring 32, and the extrusion rod 34 squeezes the airbag 35. A raised position is set on one side of the airbag 35, so when the airflow is at the raised position, it will further bulge, and then pad the bottom of the plate set at the bottom of the electrical component 1, further buffering the electrical component 1.
[0022] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: It also includes a guiding mechanism 4, which includes a motor 41, a rotating shaft 42, a first bearing 43, a belt 44 and a support assembly 45. The motor 41 in the guiding mechanism 4 is installed on one side inside the electrical component 1, and the output end of the motor 41 is connected to one end of the rotating shaft 42. The rotating shaft 42 is rotatably installed on the bracket inside the electrical component 1 through the first bearing 43, and the rotating shaft 42 is connected to the first bearing 43 through the belt 44.
[0023] The support assembly 45 in the guide mechanism 4 includes a protruding block 451, an extruding block 452, a second spring 453, a second bearing 454, an elastic rod 455, and a third bearing 456. The protruding block 451 is fixedly mounted on the outer wall of the first bearing 43. One end of the second spring 453 is connected to the second bearing 454, and the other end is connected to the extruding block 452. The elastic rod 455 is connected to the first bearing 43 through the third bearing 456.
[0024] A control switch is provided at the bottom center of the parachute 31 . The control switch is electrically connected to the motor 41 through an electric wire and is used to control the start of the motor 41 .
[0025] During the rotation of the first bearing 43 , the centrifugal force thereof causes the elastic rod 455 to overcome the pulling force of the second spring 453 and extend. During the extension process, the elastic rod 455 pulls the second spring 453 through the second bearing 454 .
[0026] Under the squeezing action of the second spring 453 , the squeezing block 452 can be stuck on the protruding block 451 , so that the elastic rod 455 is buffered by the elasticity of the second spring 453 .
[0027] After the elastic rod 455 rotates and contacts the ground, it will drive the electrical component 1 to move in a certain direction, thereby guiding the direction of the electrical component 1 after it falls to the ground; The guide mechanism 4 includes a motor 41, a rotating shaft 42, a first bearing 43, a belt 44 and a support assembly 45; The support assembly 45 includes a protruding block 451 , an extruding block 452 , a second spring 453 , a second bearing 454 , an elastic rod 455 , and a third bearing 456 ; A control switch is provided at the bottom of the parachute 31. When the parachute 31 pulls the first spring 32, the motor 41 is started. The motor 41 drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the belt 44 to rotate, thereby causing the first bearing 43 to rotate accordingly. The first bearing 43 drives the elastic rod 455 to rotate during the rotation process. The elastic rod 455 can rotate through the third bearing 456. In the initial state, the elastic rod 455 is close to the first bearing 43 under the elastic pull of the second spring 453. The extrusion block 452 is a magnetic block, which is adsorbed on the outer wall of the first bearing 43. Then, the first bearing 43 rotates under the centrifugal force. The elastic rod 455 extends, causing the elastic rod 455 to collide with the ground. When the elastic rod 455 is extended, it will pull the second spring 453 through the second bearing 454, thereby driving the extrusion block 452 to move. At this time, the movement of the extrusion block 452 will continue to approach the position of the elastic rod 455, and the extrusion block 452 will be stuck in the protrusion block 451 under the extrusion of the second spring 453, thereby making the elastic rod 455 buffered by the elasticity of the second spring 453, and the rotation of the elastic rod 455 after contacting the ground will drive the movement of the electrical component 1, thereby guiding the bumping direction of the electrical component 1 after landing.
[0028] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
