Description

Technical Field

[0001] This utility model relates to the field of resistance testers, and in particular to a laboratory instrument tester. Background Technology

[0002] Instruments and meters are tools or equipment used to detect, measure, observe, and calculate various physical quantities, material composition, physical property parameters, etc. They are mostly used in laboratory settings and come in a wide variety of types. They can be broadly classified into electronic and non-electronic types. In order to ensure that electronic instruments and meters can accurately obtain experimental data, resistance testers are usually used regularly to test and calibrate the resistance of electronic instruments and meters to ensure that the instruments and meters can operate normally. It is an important instrument and meter testing tool.

[0003] In existing technologies, resistance testers on the market typically lack a good storage structure. When using a resistance tester to test electronic instruments in the laboratory, a certain number of connecting cables and test plugs are usually used. After the test is completed, since the resistance tester itself does not have a storage structure, if the connecting cables and test plugs are not stored in a unified manner and are placed haphazardly elsewhere, it is easy to lose the connecting cables and test plugs, resulting in a lot of time spent searching for them the next time. Furthermore, careless placement may damage the components, affecting their lifespan and the smooth progress of the test. Therefore, there is a need for a laboratory instrument testing device.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-6This utility model discloses a laboratory instrument testing device, comprising a resistance tester 1. Multiple connecting rods 2 are fixedly connected to the lower surface of the resistance tester 1. A storage box 3 is fixedly connected to the lower surface of the connecting rods 2. Support blocks 4 are fixedly connected to the lower surface of the storage box 3. There are two support blocks 4 symmetrically distributed. A sliding box 5 is slidably connected to the inner surface of the storage box 3. A limiting block 6 is fixedly connected to the lower surface of the sliding box 5. The outer surface of the limiting block 6 is slidably connected to the storage box 3. Four connecting slots 17 are provided on the storage box 3. Connecting shafts 7 are fixedly connected to the inner side walls of the groove 17. The same handle 8 is rotatably connected to the two corresponding connecting shafts 7. A pull rod 13 is fixedly connected to the front surface of the sliding box 5. The pull rod 13 provides a force point for the sliding box 5, making it easy to pull the sliding box 5 out of the storage box 3. A limiting groove 14 is provided on the storage box 3. The outer surface of the limiting block 6 is slidably connected to the limiting groove 14. The limiting groove 14 allows the sliding box 5 and the limiting block 6 to move smoothly while preventing the sliding box 5 from detaching from the storage box 3.

[0028] The inner surface of the storage box 3 is rotatably connected to two anti-detachment blocks 9. The side surfaces of the two anti-detachment blocks 9 are fixedly connected to movable blocks 10. The side surfaces of the two movable blocks 10 are fixedly connected to insert rods 11. The front surface of the storage box 3 is fixedly connected to two positioning blocks 12. The outer surfaces of the two insert rods 11 are movably connected to the two positioning blocks 12 respectively. The positioning blocks 12 are provided with positioning grooves 15. The outer surfaces of the insert rods 11 are movably connected to the positioning grooves 15. The storage box 3 is provided with anti-detachment grooves 16. The outer surfaces of the anti-detachment blocks 9 are rotatably connected to the anti-detachment grooves 16. The rear surface of the movable blocks 10 is in contact with the storage box 3.

[0029] Working principle: After the resistance tester 1 is used, by rotating the plug rod 11, the plug rod 11 and the movable block 10 can rotate around the anti-detachment block 9 as the central axis. During the rotation of the movable block 10, the anti-detachment block 9 will rotate within the anti-detachment groove 16. When the rotating plug rod 11 disengages from the positioning groove 15 on the positioning block 12, the fixing of the sliding box 5 can be released. Then, by pulling the lever 13, the sliding box 5 and the limiting block 6 can be moved, allowing the sliding box 5 to be partially pulled out of the storage box 3. At this time, accessories such as connecting wires and test plugs can be placed in the sliding box 5. After the accessories are placed, pushing the lever 13 will allow the sliding box 5 to re-enter the storage box 3. When the sliding box 5 is fully inserted into the storage box 3, not only can the connecting wires, test plugs, and other accessories be stored, but the plug rod 11 can also be pulled out of the storage box 3. The insertion rod 11 is aligned with the positioning groove 15. Then, the insertion rod 11 is rotated in the opposite direction, causing the insertion rod 11 and the movable block 10 to rotate in the opposite direction around the anti-disengagement block 9 as the central axis. The anti-disengagement block 9 is also rotated in the opposite direction. When the rotating insertion rod 11 is inserted into the positioning groove 15, the slide box 5 and other structures are fixed, preventing the slide box 5 from moving freely and opening. This improves the stability of the accessories in the slide box 5. When the entire instrument needs to be moved, the handle 8 is rotated around the connecting shaft 7 as the central axis. Under the action of the connecting groove 17, the rotation angle of the handle 8 is limited. When the rotating handle 8 comes into contact with the connecting groove 17, the inner wall of the connecting groove 17 can abut against the handle 8, preventing the handle 8 from continuing to rotate. At this time, lifting the handle 8 can move the entire instrument, increasing the overall practicality of the instrument.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
