Description

Technical Field

[0001] This utility model relates to the field of instrument and meter testing, and in particular to a multifunctional instrument and meter testing device. Background Technology

[0002] Multifunctional instruments typically refer to devices capable of performing multiple measurement, monitoring, or analysis tasks. These instruments are usually designed for scientific research, engineering technology, medical diagnosis, environmental monitoring, and other fields. They can achieve multiple functions by integrating different sensors, probes, or analysis modules. After the instruments are manufactured, testing devices are required to ensure the performance stability and applicability of the instruments in different working environments.

[0003] Chinese patent CN219284579U discloses a waterproof testing device for instruments and meters. By using external force to move the fixing clamps, the two ends of the instrument are placed between the clamps. Releasing the clamps allows the instrument's outer casing to be pressed together by a tension spring, enabling waterproof testing. This device eliminates the need to replace the fixing clamps for instruments of different sizes, and the clamping effect is good, improving testing efficiency.

[0004] In the existing technology, although the above-mentioned documents can fix instruments of different sizes, in the actual testing process, only a single instrument can be fixed and tested. However, since a large number of instruments are produced, it is impossible to fix and test multiple instruments at the same time. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multifunctional instrument testing device that can simultaneously perform fixed testing on multiple instruments.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A multifunctional instrument testing device includes a base, a connecting seat fixedly connected to the top of the base, a water tank provided at the top of the base, an electric telescopic rod extending through the inner wall of the connecting seat, a connecting plate fixedly connected to the movable end of the electric telescopic rod, a movable tube extending through and rotatably connected to the middle of the connecting plate, a support plate fixedly connected to the left end of the movable tube, a cylinder fixedly connected to the bottom end of the support plate, a movable plate slidably connected to the outer wall of the cylinder, a limit mechanism provided on the inner wall of the movable plate, and a clamping plate hinged to the top of the movable plate via a hinge rod.

[0008] The outer wall of the movable tube is elastically connected to the connecting plate by a torsion spring. An inclined plate is fixedly connected to the outer wall of the right end of the movable tube, and a fixing plate is fixedly connected to the inner wall of the water tank.

[0009] The outer wall of the movable tube is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the connecting plate.

[0010] The outer wall of the inclined plate is in contact with the top of the fixed plate.

[0011] The top of the movable plate is hinged to one end of the hinge rod, and the other end of the hinge rod is hinged to the bottom end of the clamping plate. The clamping plate is slidably connected to the inner wall of the support plate.

[0012] The limiting mechanism includes a limiting block that is slidably connected to the inner wall of the moving plate. The inner sidewall of the limiting block is elastically connected to the moving plate by a return spring.

[0013] The inner sidewall of the limiting block is fixedly connected to one end of the reset spring, and the other end of the reset spring is fixedly connected to the outer wall of the moving plate.

[0014] The limiting block is inserted into the outer wall of the cylinder.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model can fix instruments and meters of the same batch at the same time by setting a movable plate, hinge rod and clamping plate, which facilitates the simultaneous testing of multiple instruments and meters and improves the overall testing efficiency to a certain extent.

[0017] 2. This utility model, by setting up a movable tube, torsion spring, inclined plate and fixed plate, allows the instrument to rotate at a certain angle. This testing method can help evaluate the mechanical stability and sealing performance of the instrument during movement or under different water pressures, and further improve the accuracy of the test.

[0025] 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.

[0026] Reference Figures 1-3 A multifunctional instrument testing device includes a base 1, with a connecting seat 2 fixedly connected to the top of the base 1. The base 1 and the connecting seat 2 mainly support and connect the water tank 3 and the electric telescopic rod 4. The water tank 3 is set at the top of the base 1, and the required amount of water for testing will be injected into the water tank 3 to facilitate subsequent waterproof testing of the multifunctional instrument.

[0027] The inner wall of the connecting seat 2 is penetrated and equipped with an electric telescopic rod 4. The electric telescopic rod 4 is an electric drive device used to convert electrical energy into linear motion. The movable end of the electric telescopic rod 4 is fixedly connected to a connecting plate 5. The connecting plate 5 mainly supports and connects the support plate 7.

[0028] A movable tube 6 is rotatably connected through the middle of the connecting plate 5. A support plate 7 is fixedly connected to the left end of the movable tube 6. A slot is provided on the support plate 7, which allows the clamping plate 13 to move laterally along the slot of the support plate 7. A cylinder 8 is fixedly connected to the bottom end of the support plate 7. A movable plate 9 is slidably connected to the outer wall of the cylinder 8.

[0029] The inner wall of the movable plate 9 is provided with a limiting mechanism. The top of the movable plate 9 is hinged to a clamping plate 13 via a hinge rod 12. The clamping plate 13 can ensure the stability of the multi-functional instrument's detection. The contact surface between the clamping plate 13 and the instrument is made of rubber material with a certain degree of elasticity, so it will not clamp the multi-functional instrument too tightly and cause damage.

[0030] Reference Figures 4-5 The outer wall of the movable tube 6 is elastically connected to the connecting plate 5 by a torsion spring 15. An inclined plate 14 is fixedly connected to the outer wall of the right end of the movable tube 6. The inclined plate 14 is set at a 30-degree angle, which allows the inclined plate 14 to contact the fixed plate 16 when it moves downward.

[0031] A fixed plate 16 is fixedly connected to the inner wall of the water tank 3. The outer wall of the movable tube 6 is fixedly connected to one end of the torsion spring 15. When the movable tube 6 rotates, it will compress the torsion spring 15. When resetting, the elastic force of the torsion spring 15 will be used to reset the movable tube 6. The other end of the torsion spring 15 is fixedly connected to the inner wall of the connecting plate 5. The outer wall of the inclined plate 14 is in contact with the top of the fixed plate 16.

[0032] Reference Figures 1-3 The top of the movable plate 9 is hinged to one end of the hinge rod 12. Since the length of the hinge rod 12 is fixed, when the movable plate 9 moves upward with one end of the hinge rod 12, the hinge rod 12 and the clamping plate 13 will move closer to each other. Conversely, when the movable plate 9 moves downward with one end of the hinge rod 12, the other end of the hinge rod 12 and the clamping plate 13 will separate from each other. The other end of the hinge rod 12 is hinged to the bottom end of the clamping plate 13. The clamping plate 13 passes through and slides on the inner wall of the support plate 7.

[0033] The limiting mechanism includes a limiting block 11, which is inclined. When the inclined surface is squeezed, the limiting block 11 will move along the inner wall of the moving plate 9. The limiting block 11 is slidably connected to the inner wall of the moving plate 9. The inner side wall of the limiting block 11 is elastically connected to the moving plate 9 through a return spring 10. The inner side wall of the limiting block 11 is fixedly connected to one end of the return spring 10. When the limiting block 11 moves to the left, it will stretch the return spring 10.

[0034] During reset, the spring force of the reset spring 10 is used to reset the limiting block 11. The other end of the reset spring 10 is fixedly connected to the outer wall of the moving plate 9. The limiting block 11 is inserted into the outer wall of the cylinder 8. The cylinder 8 has multiple slots, and the slots match the limiting block 11.

[0035] Working principle: When waterproof testing of multi-functional instruments and meters of the same batch and model is required, simply place each multi-functional instrument and meter between the two sets of clamping plates 13, and then move the moving plate 9 to move the hinge rod 12 upward, so that the hinge rod 12 and the clamping plates 13 move closer to each other and fix the multi-functional instrument and meter.

[0036] When the moving plate 9 moves upward, it will cause the outer wall groove of the cylinder 8 to press against the inclined surface of the limiting block 11, causing the limiting block 11 to move outward and stretch the return spring 10, so that the limiting block 11 and the outer wall groove of the cylinder 8 separate. After the limiting block 11 and the outer wall groove of the next cylinder 8 coincide, the reverse elastic force of the return spring 10 will be used to reset the limiting block 11, so that the limiting block 11 can be inserted into the outer wall groove of the cylinder 8.

[0037] When it is necessary to put the multi-functional instrument into the water tank 3 for testing, simply start the electric telescopic rod 4 to move the electric telescopic rod 4, connecting plate 5, movable tube 6, support plate 7 and inclined plate 14 downwards, so that the water covers the top of the clamp plate 13. At this time, observe whether there are air bubbles in the water tank 3 to determine whether the multi-functional instrument has a sealing problem.

[0038] When further testing is required, simply continue to start the electric telescopic rod 4 and move the connecting plate 5, movable tube 6, support plate 7 and inclined plate 14 downwards for a short distance, so that the inclined plate 14 contacts the fixed plate 16 and is squeezed. Let the inclined plate 14 rotate counterclockwise, moving the movable tube 6, support plate 7, cylinder 8 and movable plate 9 to a certain angle. When the movable tube 6 rotates, it will compress the torsion spring 15. At this time, observe whether there is any leakage when the multi-functional instrument seals and connections rotate in the water.

[0039] After the test is completed, the electric telescopic rod 4 moves the connecting plate 5, the movable tube 6, the support plate 7 and the inclined plate 14 upwards. Meanwhile, the movable tube 6 uses the reverse elastic force of the torsion spring 15 to slowly rotate the support plate 7, the movable tube 6, the cylinder 8 and the movable plate 9 clockwise back to the initial state.

[0040] When it is necessary to release the clamp on the multi-functional instrument, simply pull the limit block 11 outward and stretch the reset spring 10 to separate the limit block 11 from the outer wall groove of the cylinder 8. Then, manually move the moving plate 9 downward with the hinge rod 12 to separate the clamping plates 13 from each other and release the multi-functional instrument.

[0041] 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.
