[0015] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-5 As shown, the dual-channel electronic measuring instrument provided in this embodiment includes a main body 1, which is an electronic measuring instrument device. The main body 1 includes, but is not limited to, a housing 101 with an opening at one end and a wiring panel 102 disposed at the opening of the housing 101. The main body 1 also includes internal components located inside the housing 101 and having other functions. The housing 101 mainly provides protection for its internal components. The wiring panel 102 is connected to the housing 101, forming a space suitable for placing the internal components. The wiring panel 102 is the key interface area for connecting the dual-channel measuring instrument to external devices, directly serving the core function of simultaneous measurement or output of the dual channels. When testing the main body 1 of the electronic measuring instrument, it is necessary to open the wiring panel 102 on the housing 101 to check the working status of the internal components.

[0017] The device also includes an insertion plate 2, elastic elements, a release assembly, and a transmission mechanism. Specifically, there are two insertion plates 2, which are symmetrically arranged on the wiring panel 102. There are two elastic elements, which are located at the opening of the housing 101. The elastic elements correspond to the positions of the insertion plates 2 and are movably engaged with the insertion plates 2. The release assembly is located on the side wall of the housing 101. The two ends of the transmission mechanism are respectively connected to the two elastic elements. The release assembly drives the two elastic elements to move synchronously through the transmission mechanism and releases the engagement state of the elastic elements with the insertion plates 2.

[0018] In use, the above structure connects the wiring panel 102 to the opening of the housing 101. When the insertion plate 2 extends into the housing 101, the insertion plate 2 will squeeze the elastic element and be finally locked in place by the elastic element, so that the wiring panel 102 is locked onto the housing 101. At this time, the inside of the housing 101 is in a closed state. When it is necessary to open the housing 101 and the wiring panel 102 to inspect the internal components of the main body 1, simply drive the release component. Under the action of the transmission mechanism, drive the two elastic elements away from the insertion plate 2, thereby releasing the locking state of the insertion plate 2. The wiring panel 102 can be pulled out in the direction away from the housing 101, thus opening the housing 101 and facilitating the inspection of the internal components of the main body 1.

[0019] Specifically, in order to achieve the above structural effect, therefore, as Figure 2As shown, the elastic element consists of a pin 5, an L-shaped movable plate 3, a sliding member, and a compression spring 4. The movable plate 3 has a parallel portion 31 and a longitudinal portion 32, which are perpendicular to each other. The parallel portion 31 is parallel to the side wall of the outer casing 101 where the movable plate 3 is located. The movable plate 3 slides on the outer casing 101 via the sliding member, which is located on the parallel portion 31. One end of the pin 5 passes through the parallel portion 31 and extends away from the side wall of the outer casing 101. The other end of the pin 5 has a limiting plate 6 that makes movable contact with the parallel portion 31. The two ends of the compression spring 4 are respectively connected to… The limiting plate 6 and the inner wall of the outer shell 101 abut against each other. When the insertion plate 2 is inserted into the outer shell 101, the insertion plate 2 has a snap-fit ​​hole 7 suitable for the end of the pin 5 to engage. The end of the insertion plate 2 near the inside of the outer shell 101 is chamfered, which makes it easy for the pin 5 to slide into the snap-fit ​​hole 7. When the insertion plate 2 pushes the pin 5, the pin 5 slides on the parallel part 31 of the moving plate 3 and compresses the compression spring 4 to store its force. When the pin 5 is snapped into the snap-fit ​​hole 7, under the push of the compression spring 4 releasing its elasticity, the pin 5 is stably snapped into the snap-fit ​​hole 7 of the insertion plate 2, and the wiring panel 102 is stably snapped into the outer shell 101.

[0020] like Figure 3 As shown, sliding grooves are provided on both sides of the outer casing 101, and the sliding grooves are suitable for the longitudinal portion 32 on the moving plate 3 to pass through. A protective shell 10 is connected to the outer side wall of the outer casing 101 at the position of the sliding groove, and a push groove 11 parallel to the longitudinal portion 32 is provided on the protective shell 10 near the release component. The release component can drive the pin 5 away from the insertion plate 2 through the moving plate 3, thereby contacting the locking state of the insertion plate 2. When the moving plate 3 moves, its longitudinal portion 32 extends into the outer protective shell 10 through the sliding groove. The protective shell 10 protects the sliding groove to prevent foreign objects and impurities from entering the outer casing 101 through the sliding groove.

[0021] Furthermore, the release assembly includes a push rod 12, a connector 13, a sliding block 14, a push block 15, and a telescopic component; wherein, an oblique groove 16 is formed on the longitudinal portion 32 of the moving plate 3 near the release assembly, the push rod 12 is slidably connected in the oblique groove 16, both ends of the connector 13 are respectively connected to the sliding block 14 and the push rod 12, the sliding block 14 is slidably connected to the push groove 11, the push block 15 is connected to the sliding block 14, the fixed end of the telescopic component is connected to the outer shell 101, and the movable end of the telescopic component is connected to the push block 15; when the push block 15 is pushed to move, it drives the sliding block 14 along the push groove. 11 moves, and the connecting piece 13 drives the push rod 12 to move on the inclined groove 16. The direction of movement of the push rod 12 is consistent with the direction of movement of the push block 15. Since the inclined groove 16 extends at an inclined position along the extension direction of the push groove 11 and there is an angle between it and the extension direction of the push groove 11, when the push rod 12 moves with the push block 15, it drives the longitudinal part 32 to move gradually into the protective shell 10 through the inclined groove 16. This causes the moving plate 3 to move towards the side wall of the outer shell 101. At this time, the parallel part 31, under the abutment of the limiting plate 6, drives the pin 5 to move synchronously, so that the pin 5 moves away from the locking hole 7.

[0022] When the movable plate 3 moves, it moves along a fixed direction under the action of the sliding member. In order to stabilize the movement of the movable plate 3, there are two sliding members, which are respectively set at both ends of the parallel part 31. The sliding member is composed of a shaft frame 8 and a sliding rod 9. The shaft frame 8 is connected to the parallel part 31, one end of the sliding rod 9 is connected to the inner side wall of the outer shell 101, and the other end of the sliding rod 9 passes through the shaft frame 8 and is slidably connected to the shaft frame 8. When the movable plate 3 moves, the shaft frame 8 moves accordingly and moves along the extension direction of the sliding rod 9.

[0023] Furthermore, the telescopic component facilitates the reset of the push block 15. The telescopic component includes a sleeve 17, a telescopic spring 18, and a telescopic rod 19. One end of the telescopic rod 19 extends into the sleeve 17 and is slidably connected to the sleeve 17. The sleeve 17 is connected to the outer casing 101. The other end of the telescopic rod 19 is connected to the push block 15. The telescopic spring 18 is located inside the sleeve 17, and its two ends are respectively connected to the ends of the sleeve 17 and the telescopic rod 19. When the push block 15 moves along the push groove 11, it will drive the telescopic rod 19 to move into the sleeve 17 and squeeze the telescopic spring 18. When the push block 15 loses external thrust, the telescopic spring 18 releases its elastic force and drives the push block 15 back to its initial position by pushing the telescopic rod 19. At this time, the moving plate 3 is also reset to its initial position.

[0024] Furthermore, to facilitate the simultaneous movement of the pins 5 on the two elastic members away from the insertion plate 2 by a single power source, making the engagement and disengagement of the insertion plate 2 more convenient, the transmission mechanism includes an active rod 20, a passive rod 21, and a bidirectional moving assembly. A fixed protrusion 22 is connected to the parallel portion 31 of the moving plate 3. One end of the active rod 20 and one end of the passive rod 21 are respectively connected to the fixed protrusions 22 on the two moving plates 3. The other ends of the active rod 20 and the passive rod 21 extend in opposite directions and are connected to the moving assembly. When the moving plate 3 containing the disengagement assembly moves, and the pins 5 move away from the engagement hole 7, the moving plate 3 drives the active rod 20 to move along the moving direction of the moving plate 3. The active rod 20 is slidably connected to the inner wall of the outer casing 101 to ensure the stability of the active rod 20 during sliding. After the active rod 20 moves, it drives the passive rod 21 to move synchronously through the bidirectional moving assembly, and the moving direction of the passive rod 21 is opposite to the moving direction of the active rod 20.

[0025] The aforementioned bidirectional moving assembly can be configured as two symmetrically arranged components. Each bidirectional moving assembly includes an active rack 23, a passive rack 24, and a transmission gear 25. The active rack 23 and passive rack 24 are respectively connected to the ends of the active rod 20 and passive rod 21 furthest from the moving plate 3. The active rack 23 and passive rack 24 are arranged parallel to each other. The transmission gear 25 is located between the active rack 23 and passive rack 24 and meshes with both. The transmission gear 25 is rotatably connected to the inner wall of the outer casing via a gear base 26. Both the active rack 23 and passive rack 24 are connected via… The bracket 27 slides on the inner wall of the housing. When the bidirectional moving assembly is running, the active rod 20 drives the active rack 23 to move, which in turn drives the passive rack 24 to move in the opposite direction of the active rack 23 through the transmission gear 25. The passive rack 24 drives the passive rod 21 to move synchronously. The passive rod 21 drives the moving plate 3 connected to it to move, which drives the pin 5 on it to move away from the locking hole 7. The pins 5 on the two elastic members move away from the locking hole 7 synchronously, thereby releasing the elastic members from the locking state of the insertion plate 2. The wiring panel 102 can then be removed from the housing 101.
