Description
Technical Field
[0001] The utility model relates to the technical field of inner cores of instruments and meters, in particular to an instrument and meter with an inner core that is easy to replace. Background Art
[0002] Instruments are key equipment widely used in various fields. Their main function is to measure, detect, monitor, record or display physical quantities, chemical quantities or other specific parameters. These devices are usually composed of components such as sensors, controllers, display screens, data loggers, etc., and can measure a variety of physical quantities such as temperature, pressure, humidity, flow, current, voltage, etc., or chemical parameters such as pH value, concentration, etc. Whether in scientific research, engineering, manufacturing, health care or environmental monitoring, instruments play an indispensable role. Common instruments include thermometers, sphygmomanometers, flow meters, pressure gauges, electric meters, dashboards, spectrometers, microscopes, astronomical telescopes, etc. They are used for experiments, observations, monitoring, control and diagnosis in various fields, providing important support for human scientific research, engineering innovation and life.
[0003] A traditional instrument that facilitates the replacement of the inner core usually consists of mechanical mechanisms such as a shell, a fixing clamping device, an inner core module, a plug-in interface, a guide structure and a fixing device. The shell is a protective shell of the entire instrument and is made of durable materials such as metal or plastic to protect the internal electronic components and mechanical structures from the influence of the external environment. The fixing clamping device includes screws, buckles, quick locks, etc., which are used to fix and release the shell to facilitate the replacement of the internal core components. The inner core module is the core part of the instrument, including components such as sensors, circuit boards, and display screens, which are detachable and easy to replace, repair or upgrade. The plug-in interface such as an electronic connector and a plug and socket facilitates the user to insert and remove the inner core module. The guiding structure such as a protrusion and a notch ensures the accurate positioning of the inner core module. The fixing device such as a buckle and a screw lock is used to fix the inner core module to prevent loosening or falling off.
[0004] However, the outer shell of a traditional instrument that is easy to replace the inner core cannot self-lock when opening and closing, which will lead to the following problems. First, the lack of a self-locking function will increase the difficulty of operation during the replacement of the inner core module, because the user needs additional means to keep the outer shell closed, which requires additional tools or manpower support. Secondly, the lack of a self-locking function will increase the operational risk during the replacement of the inner core module, because the outer shell may be accidentally opened, resulting in exposure or damage to internal components, and may even cause personal injury. In addition, the lack of a self-locking function may cause the instrument to open accidentally during transportation or use, thereby causing safety hazards or data corruption. For this reason, an instrument that is easy to replace the inner core is proposed to solve the above problems. Utility Model Content

[0033] Specifically, when using an instrument that is easy to replace the inner core, first pull the handle 2 to apply force to it and drive the top plate 24 at the bottom to rotate. The rotation of the top plate 24 causes the first connecting block 5 on one side to rotate as well, and at the same time, the force applied to the first connecting block 5 causes the second fixed column 6 at the bottom to move. The movement of the second fixed column 6 drives the limiting ball 7 at the bottom to move, so that the limiting ball 7 is separated from the inner wall of the semicircular plate 8. At the same time, the semicircular plate 8 is subjected to force, driving the first connecting plate 9 to move, and the movement of the first connecting plate 9 causes the first spring 10 at the bottom to contract. At the same time, the semicircular plate 8 rotates inside the support plate 11, achieving the effect of a self-locking top plate 24.
[0034] Reference Figure 1 , Figure 4 and Figure 3The fixing assembly includes a handle 2, the bottom of the handle 2 is fixedly connected to the top of the top plate 24, the side wall of the first shell 1 is fixedly connected to a U-shaped plate 15, the inner wall of the U-shaped plate 15 is fixedly connected to a third fixing column 16, the outer wall of the third fixing column 16 is rotatably connected to a collar 14, the outer wall of the collar 14 is fixedly connected to a second connecting block 13, the side wall of the second connecting block 13 is fixedly connected to the side wall of the top plate 24, the bottom of the first shell 1 is fixedly connected to a first fixing column 3, the outer wall of the first fixing column 3 is fixedly connected to a support rod 4, the side wall of the first shell 1 is fixedly connected to a fixing block 18, the inside of the fixing block 18 is slidably connected to a connecting column 22, the inside of the fixing block 18 is rotatably connected to a fixing rod 23, the top of the fixing rod 23 is fixedly connected to a baffle 19, a second spring 20 is arranged inside the fixing block 18, one end of the second spring 20 is fixedly connected to a hollow column 21, and the hollow column 21 is slidably connected to the inside of the fixing block 18.
[0035] Specifically, next, the electronic component is passed through the inclined surface of the baffle 19 so that it is stuck at the bottom of the baffle 19. Subsequently, the second spring 20 inside the fixed block 18 is squeezed by force, and the contraction of the second spring 20 drives the hollow column 21 to move. At the same time, the hollow column 21 is against the side wall of the fixed rod 23. Subsequently, by setting the connecting column 22, the rotation of the fixed rod 23 is limited, thereby achieving the effect of fixing the electronic component. At the same time, the top plate 24 is forced to drive the second connecting block 13 of the side wall to rotate. The rotation of the second connecting block 13 further drives the ring 14 to rotate, and there is a third fixing column 16 on the inner wall of the ring 14. The rotation of the third fixing column 16 is on the inner wall of the U-shaped plate 15. At the same time, the side wall of the U-shaped plate 15 is fixed to the side wall of the first shell 1. The effect of controlling opening and closing is achieved.
[0036] Reference Figure 3 A fan 17 is fixedly connected inside the first housing 1 .
[0037] Specifically, the fan 17 inside the first housing 1 then rotates, and the rotation of the fan 17 effectively promotes air flow, thereby accelerating the heat dissipation effect. The rotation of the fan 17 drives the surrounding air to flow, taking away heat from the electronic components and internal structures, and keeping the device running within a safe temperature range. This can improve the performance and reliability of the device and extend its service life.
[0038] Working principle: when using an instrument that is easy to replace the inner core, first pull the handle 2, and the handle 2 is forced to drive the top plate 24 at the bottom to rotate, and the rotation of the top plate 24 drives the first connecting block 5 on one side to rotate, and at the same time, the force of the first connecting block 5 drives the second fixed column 6 at the bottom to move, and the movement of the second fixed column 6 drives the bottom limiting ball 7 to move, and at the same time, the movement of the limiting ball 7 makes the limiting ball 7 separate from the inner wall of the semicircular plate 8, and at the same time, the force of the semicircular plate 8 drives the first connecting plate 9 to move, and the movement of the first connecting plate 9 drives the first spring 10 at the bottom to contract, and at the same time, the semicircular plate 8 rotates inside the support plate 11, achieving the effect of self-locking the top plate 24, and at the same time, the force of the top plate 24 drives the second connecting block 13 of the side wall to rotate, and the second connecting block The rotation of 13 drives the ring 14 to rotate, and the inner wall of the ring 14 rotates with a third fixed column 16, and the third fixed column 16 rotates on the inner wall of the U-shaped plate 15, and the side wall of the U-shaped plate 15 is fixed to the side wall of the first shell 1, thereby achieving the effect of controlling the opening and closing, and then the fan 17 inside the first shell 1 rotates, and the rotation of the fan 17 achieves the effect of heat dissipation.
