Description

Technical Field

[0001] This invention relates to the field of universal meter testing, and more specifically, to a universal meter testing tray. Background Technology

[0002] There are many types of meters, including instruments, multimeters, ammeters, and voltmeters. Taking an instrument as an example, when an instrument is actually tested, it needs to be fixed with a clamp first, and then the electrodes used to test the instrument are inserted into the insertion end of the instrument to achieve the test.

[0003] Chinese Patent Publication No. CN210968580U, published on July 10, 2020, discloses a universal instrument testing fixture. This fixture uses a threaded rod to change the distance between connecting blocks on both sides, allowing it to adapt to instruments of different shapes and offering ease and flexibility of use. However, the fixture has the following drawbacks: because it only uses the force of a spring to push the connecting blocks, which then clamp the instrument, the degree of spring compression varies depending on the length and width of the instrument. This results in different clamping forces for different models, leading to varying stability when different instruments are clamped. Consequently, the instrument may easily detach from the fixture during testing, affecting the testing results. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing technologies where instruments are unstable when clamped and easily detach from the clamp. It provides a universal instrument testing tray that provides stable instrument clamping and has a connecting mechanism for easy replacement of different models of clamping trays, thus adapting to the clamping of various instrument models.

[0007] The clamping tray includes a connecting tray and a clamping flap. The clamping flap is rotatably mounted on one side of the connecting tray, and the connecting tray and the connecting base plate are fixedly connected by a connecting structure.

[0008] In this invention, by setting a clamping tray, the instrument can be stably clamped during testing, ensuring stability during testing. By setting a connecting structure between the connecting base plate and the clamping tray, the connection and installation between the connecting base plate and the connecting tray can be facilitated, and the clamping tray can be easily replaced. The model of the clamping tray can be changed according to the type of instrument, thereby facilitating the testing of different instruments.

[0014] The connecting spring allows the flip plate to be firmly clamped onto the instrument, automatically securing it. When the flip plate is open, it remains open, making it easy to install the instrument onto the connecting tray.

[0015] Preferably, limit baffles are provided on both sides of the connecting tray in the width direction, and limit blocks are provided at both ends of both sides of the connecting tray in the length direction, which are connected to the limit baffles.

[0016] The combination of the limiting baffle and the limiting block forms an area for placing the instrument; the draft angle is set so that the instrument can be placed in the area formed by the limiting baffle and the limiting block.

[0017] Preferably, the sliding assembly includes a slider and a slide rail, with the slider fixedly disposed at the bottom of the clamping tray and sliding in cooperation with the slide rail.

[0047] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0048] Example 1: Refer to Figures 1 to 5As shown, a universal meter testing tray is mounted on a testing mounting plate 7. The testing mounting plate 7 is also provided with a testing module 71 for testing instruments, and the testing module 71 is provided with testing electrodes 72 that cooperate with the instrument's interface. The universal meter testing tray mainly includes a slidingly mounted connecting base plate 41 and a clamping tray 1.

[0049] A sliding assembly 4 is provided below the connecting base plate 41 to drive it to slide; the sliding assembly 4 includes a slider 42 and a slide rail 43. One end of the slide rail 43 corresponds to the detection electrode 72. The slider 42 is fixedly installed at the bottom of the clamping tray 1. The slider 42 and the slide rail 43 cooperate to slide, so that the connecting base plate 41 can slide stably along the slide rail 43.

[0050] The clamping tray 1 includes a connecting tray 2 and a clamping flap 3, with the clamping flap 3 rotatably mounted on one side of the connecting tray 2. Limiting baffles 25 are provided on both sides of the connecting tray 2 in the width direction, and limiting blocks 26 connected to the limiting baffles 25 are provided at both ends of both sides of the connecting tray 2 in the length direction. A notch is formed between the limiting blocks 25 on both sides, allowing the detection electrode 72 to be easily inserted into the instrument's interface during testing. The inner surfaces of the limiting baffles 25 and the limiting blocks 26 are provided with a certain draft angle, allowing the instrument to be easily placed into the area formed by the limiting baffles 25 and the limiting blocks 26.

[0051] The clamping flap 3 includes a flipping bracket 31 and a flipping plate 32. One side of the flipping bracket 31 is rotatably connected to the connecting tray 2, and the other side of the flipping bracket 31 is fixedly connected to the flipping plate 32. Specifically, the flipping bracket 31 is arranged on both sides of the flipping plate 32, and mounting plates 22 are fixedly arranged on both sides of the connecting tray 2 in the width direction. A mounting rod 23 is fixedly arranged between the two mounting plates 22. A connecting plate 311 is arranged on the flipping bracket 31 at a certain angle to the flipping bracket 31, so that the flipping bracket 31 is in an "L" shape. The connecting plate 311 is rotatably connected to the upper end of the mounting plate 22. A connecting rod 312 is arranged between the two flipping brackets 31, and a connecting spring 24 is arranged between the connecting rod 312 and the mounting rod 23. The connecting spring 24 is in a contracted state. When the clamping flap 3 clamps the instrument, the projection of the horizontal plane of the connecting rod 312 is located on the side of the mounting rod 23 closer to the instrument. That is to say, the axis of the connecting rod 312 and the axis of the mounting rod 23 are not in the length direction of the mounting plate 22. The connecting spring 24 is designed so that when the flip plate 32 clamps the instrument, the tension of the connecting spring 24 is transmitted to the flip plate 32 through the connecting rod 311, which can clamp the instrument. In addition, when the flip plate 32 is flipped open, during the flipping process, the connecting rod 312 only needs to pass directly above the mounting rod 23, and the connecting rod 32 can move under the action of the connecting spring 24, so that the flip plate 32 is flipped to the other side, and the flip plate 32 is in the open state.

[0052] A photoelectric sensor 321 and an infrared sensor 322 are provided on the flip plate 32. The photoelectric sensor 321 is used to detect whether the instrument under test is placed on the connecting tray 2, and the infrared sensor 322 is mainly used to transmit relevant data.

[0053] Since various models and types of instruments have different sizes during testing, in order to make the clamping tray 1 adaptable to the testing of different types of instruments, the connecting tray 2 is designed to be compatible with various models and types of instruments. Therefore, in order to facilitate the replacement of the connecting tray 2 and make it easy to test various models and types of instruments, the connecting tray 2 and the connecting base plate 41 are fixedly connected by a connecting structure.

[0054] The connecting structure mainly includes two connecting bottom holes 411 fixedly installed on the connecting base plate 41. The connecting bottom holes 41 are located on both sides of the connecting base plate 41 in the width direction. The side walls of both sides of the connecting base plate 41 are provided with limiting through holes 412 communicating with the connecting bottom holes 411. The bottom of the connecting tray 2 is fixedly provided with a connecting plug 21 that mates with the connecting bottom holes 411. The connecting plug 21 is provided with a connecting plug 211 that mates with the limiting through holes 412. The connector passes through the limiting through holes 412 and mates with the connecting plug 211. In order to make it easier for the connecting tray 2 to connect with the connecting base plate 41, a chamfer structure is provided at the bottom of the connecting plug 21, so that the connecting plug 21 can be easily inserted into the connecting bottom holes 411. In this embodiment, the connector is set as a rotating plunger. The rotating plunger has the characteristics of easy insertion and removal, and can be tightly inserted into the limiting through holes 412 and the connecting through holes 211, so that the connecting plug 21 can be stably fixed in the connecting bottom holes 411. When it is necessary to replace the clamping tray 1, simply pull the connector out of the connecting bottom hole 411 and the limiting through hole 412 to remove the connecting tray 2 from the connecting base plate 41. Then, insert the connecting plug on the new clamping tray into the connecting base plate 411, and then pass the connector through the limiting through hole 412 and the connecting plug 211 to complete the replacement of the clamping tray 1.

[0055] The working principle of this embodiment is as follows: In this embodiment, when in use, the universal meter testing tray is first pulled along the slide rail 43 so that the entire clamping tray 1 is away from the testing module 71. Then, the clamping flip plate 3 is flipped open, and the meter to be tested is placed on the connecting tray 2, so that the plug interface on the meter faces the testing module 71. Then, the clamping flip plate 3 is flipped back to its original position so that the clamping flip plate 3 and the connecting tray 2 clamp the meter. Then, the clamping tray 1 is pushed to move closer to the testing module 71 so that the testing electrode 72 on the testing module 71 is inserted into the meter's plug interface to test the meter. After the test is completed, the above steps are repeated, the tested meter is taken out and a new meter is tested.

[0056] In this invention, by setting the clamping tray 1, the instrument can be stably clamped during testing, thus maintaining stability during testing. By setting a connecting structure between the connecting base plate 41 and the clamping tray 1, the connection and installation between the connecting base plate 41 and the connecting tray 2 can be facilitated, and the clamping tray 1 can be easily replaced. The model of the clamping tray 1 can be changed according to the type of instrument, thereby facilitating the testing of different instruments.

[0057] Example 2: Refer to Figures 1 to 5 As shown, this embodiment is similar in structure to embodiment 1, except that a thrust mechanism 5 is provided on both sides of the connecting base plate 41. The thrust mechanism 5 mainly includes a thrust block 51, a fixing block 52 and a thrust spring 54.

[0058] The thrust block 51 is fixedly installed at the bottom of the connecting base plate 41, and the thrust block 51 is provided with a through hole 511; the fixing block 52 is fixedly installed on the detection mounting plate 7 and is located on the side of the thrust block 51 near the clamping flip plate 3, the fixing block 52 is provided with a guide rod 53, the guide rod 53 is set along the sliding direction of the connecting base plate, and the end of the guide rod 53 away from the fixing block 52 passes through the through hole 511; the thrust spring 54 is sleeved on the guide rod 53 and its two ends abut against the fixing block 52 and the thrust block 51 respectively.

[0059] In this embodiment, the force exerted by the thrust spring 54 on the thrust block 51 enables the clamping tray 1 to move continuously toward the detection module 71, so that the clamping tray 1 can maintain contact with the detection module 71 when the instrument is being tested, making the test more stable.

[0060] Example 3: Reference Figure 6As shown, this embodiment is similar in structure to embodiment 1 or embodiment 2, except that the connecting base plate 4 is provided with a transmission plate 413 on the side near the clamping flip plate 3, and a transmission column 414 is provided below the transmission plate 413. The transmission column 414 is connected to the movable end of the moving device 6. In this embodiment, the moving device 6 is configured as a telescopic cylinder, and the telescopic rod of the telescopic cylinder is connected to the transmission column 414.

[0061] The movement of the telescopic cylinder enables the clamping tray 1 to move closer to or further away from the detection module 71, facilitating the replacement of the instrument being tested.

[0062] Example 4: Reference Figure 6 As shown, this embodiment is similar in structure to embodiment 3, except that, in order to make it easier to replace the instrument and the clamping tray 1, the connecting plate 311 extends along the length of the connecting plate 311 at the end away from the flip plate 32. Then, an abutment head 313 is provided at the end of the connecting plate 311 away from the flip plate 32. A flipping stop 61 and a reset guide rail 62 are respectively provided on both sides of the abutment head 313 along the movement direction of the telescopic cylinder 6. The reset guide rail 62 is located at the end away from the moving device 6, and the abutment head 313 is located at the end close to the moving device 6. The reset guide rail 62 is the side of the reset baffle and includes an inclined guide rail 621, an arc transition guide rail 622, and a horizontal guide rail 623.

[0063] The working principle of this embodiment is as follows: When the moving device 6 pulls the connecting tray 2 away from the detection module 71, when the connecting tray 2 is about to reach the end point, the abutment head 311 contacts the flipping stop 61, and the connecting tray 2 continues to move. Due to the blocking effect of the flipping stop 61, the abutment head 61 rotates around the rotation point between the connecting plate 311 and the mounting plate 22. Due to the setting of the connecting spring 24, only the abutment head 313 needs to drive the connecting plate 311 to rotate, so that the connecting rod 312 passes over the mounting rod 23, and the clamping flip plate 3 can continue to flip under the action of the connecting spring 24, so that the clamping flip plate 3 is fully opened. At the same time as the clamping flip plate 3 opens, the connecting tray 2 also moves to the end point, and the connecting rod 311 is parallel at this time. At this point, the abutment head 313 abuts against the horizontal guide rail. Then, the instrument is placed on the connecting tray 2, and the moving device 6 pushes the connecting tray 2 closer to the detection module 71. During the movement of the connecting tray 2, the abutment head 313 moves sequentially along the horizontal guide rail 623, the arc transition guide rail 622, and the inclined guide rail 621. When the abutment head 313 contacts the arc transition guide rail 622, the connecting plate 311 rotates. Due to the action of the connecting spring 24, the connecting rod 312 rotates past the mounting rod 23, and the clamping flip plate 3 continues to rotate under the action of the connecting spring 24, allowing the clamping flip plate 3 to clamp the instrument. This achieves automatic clamping of the instrument as the connecting tray 2 approaches the detection module 71. Therefore, by moving the connecting tray 2 with the moving device 6, the flip plate 32 can automatically flip, achieving automatic opening and closing of the clamping tray 1.

[0064] It should be noted that in this embodiment, the flipping stop 61 and the reset guide rail 62 are both installed on the detection mounting plate 7, so they will not be affected when the connecting tray 2 is replaced; at the same time, the function of the reset stop 61 and the reset guide rail 62 is only to allow the connecting rod 312 to pass over the mounting rod 23, and then the flipping plate 32 is flipped by the action of the connecting spring 24.

[0065] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
