Description

Technical Field

[0001] This utility model relates to the field of multimeters, and more particularly to a portable multimeter. Background Technology

[0002] In the production of medicated patches, multimeters play a crucial role in maintaining and debugging the electronic equipment and circuits of the production line. They are indispensable multi-functional electronic measuring instruments. Multimeters can measure electrical parameters such as voltage, current, and resistance; some advanced models even have functions such as capacitance measurement, diode testing, and temperature measurement. These functions are key to ensuring the stable operation of the medicated patch production line and the quality of the products.

[0003] However, existing multimeter designs have limitations in environments with strict hygiene requirements, such as medicated patch production. In particular, the separate structure of the probes from the body and the long connecting cable may pose a risk of contamination and cause inconvenience. In the production process of medicated patches, there are strict hygiene requirements, and any possible source of contamination must be strictly controlled. The existing multimeter's separate probe and body design, coupled with the long connecting cable, is not only cumbersome to use, but may also become a carrier of contaminants such as dust and microorganisms. These contaminants may be carried to different parts of the production line during testing, affecting the hygienic quality of the medicated patches and the cleanliness of the production environment. Furthermore, the existing multimeter's separate probe and body design makes it inconvenient to carry and use.

[0004] Therefore, a portable multimeter has now been developed that can store the probes and connecting cables inside the meter body, making it convenient to carry, store, and use the multimeter as a whole. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a portable multimeter that can store the probes and connecting wires inside the multimeter body, making it convenient to carry, place and use the multimeter as a whole.

[0006] The technical solution is as follows: A portable multimeter includes a body, winding posts, a plug, a retractable cable, a connecting cable, test leads, and a locking cover. The upper left and right sides of the body have storage openings. The body is the main structure and is used to house electronic components. Multiple connecting ports are located on the upper front of the body, and symmetrically arranged mounting holes are located on the front of the body. Winding posts are connected to the lower left and right sides of the body, and plugs are snapped into the mounting holes. Retractable cables are connected to the plugs. Connecting cables are wound between the winding posts on both sides, and test leads are connected to the connecting cables. The test leads contact the tops of the winding posts, and the connecting cables connect to adjacent retractable cables. Locking covers are rotatably connected to the storage openings, contacting the test leads and restricting their movement.

[0007] Furthermore, a control knob is provided on the watch body for operating the multimeter.

[0008] Furthermore, anti-slip pads are provided on both the left and right sides of the watch body to increase the grip friction between the watch and the hand.

[0009] Furthermore, it also includes a dust cover. Each connection port is equipped with a dust cover, which is rotatably connected to the watch body. The dust cover is used to prevent dust from entering the connection port. The dust cover has an elastic structure and has downward elasticity to increase the sealing performance.

[0010] Furthermore, it also includes a protective sleeve, with protective sleeves installed at each mounting hole. The plug passes through the protective sleeve, which is used to protect the plug.

[0011] Furthermore, it also includes retaining buckles. Retaining buckles are connected to the front of both the left and right sides of the watch body. The connecting wire is inserted into the retaining buckle, which is used to keep the connecting wire neat.

[0012] The beneficial effects of this utility model are: by winding the connecting wire between the winding posts and fixing the test leads with the locking cover, the test leads and connecting wire can be stored inside the multimeter body, making it convenient for the multimeter to be carried, placed and used as a whole. This can avoid contamination of the production of medicated patches and improve the controllability of the multimeter during use. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0021] A portable multimeter, such as Figures 1-6 As shown, the multimeter includes a body 1, a dust cover 5, a protective sleeve 6, a retaining clip 7, a winding post 8, a plug 9, a retractable cable 10, a connecting cable 11, test leads 12, and a locking cover 13. The upper left and right sides of the body 1 have storage openings 2. The body 1 is the main structure used to house electronic components. A control knob is located on the body 1 for operating the multimeter. Anti-slip pads are provided on both sides of the body 1 to increase grip friction with the hand. Multiple connection ports 3 are located on the upper front of the body 1 for connecting... Each interface 3 is equipped with a dust cover 5. The dust cover 5 has an elastic structure and is press-down elastic to increase sealing performance. The dust cover 5 is rotatably connected to the body 1. The dust cover 5 is used to prevent dust from entering the connection port 3. The front side of the body 1 has symmetrically arranged mounting holes 4. The lower left and right sides of the body 1 are connected to winding posts 8. The mounting holes 4 are all fitted with plugs 9. Each mounting hole 4 is equipped with a protective sleeve 6. The plug 9 passes through the protective sleeve 6 and is used to protect the plug 9. A telescopic cord 10 is connected, and connecting cords 11 are wound between the winding posts 8 on both the left and right sides. Fixing buckles 7 are connected to the front of both the left and right sides of the meter body 1. The connecting cords 11 are inserted into the fixing buckles 7, which are used to straighten the connecting cords 11. Test leads 12 are connected to each connecting cord 11. The plug 9 is pulled out of the mounting hole 4 and inserted into the connection port 3. The meter body 1 is then activated to perform measurements with the test leads 12. The test leads 12 contact the top of the winding posts 8, and the connecting cords 11 connect to the adjacent telescopic cords 10. The connection and storage port 2 are both rotatably connected to a locking cover 13. The locking cover 13 contacts the probe 12 and restricts the movement of the probe 12. When the probe 12 is removed by the locking cover 13, the connecting wire 11 naturally detaches from the winding post 8. The meter body 1 can then be started to perform measurement operations with the probe 12. When not in use, the connecting wire 11 is wound around the winding post 8 and the probe 12 is fixed by the locking cover 13, so that the probe 12 and the connecting wire 11 can be stored in the meter body 1.

[0022] In the production of medicated patches, multimeters play a crucial role in maintaining and debugging the electronic equipment and circuits of the production line. However, existing multimeter designs have limitations in the environment of medicated patch production, which has strict hygiene requirements. The existing multimeter's separate probes and body design, coupled with the long connecting cable, not only makes it cumbersome to use but also can become a carrier of contaminants such as dust and microorganisms. These contaminants may be carried to different parts of the production line during testing, affecting the hygienic quality of the medicated patches and the cleanliness of the production environment. Therefore, this utility model was designed. In use, the multimeter is first removed by rotating the locking cover 13 to remove the probes 12, and the connecting cable 11 naturally detaches from the winding post 8. Then, the dust cover 5 is rotated open. Pull the plug 9 out of the mounting hole 4 and insert it into the connection port 3. Start the meter body 1 to perform measurement operations with the probes 12. When not in use, wind the connecting wire 11 between the winding posts 8 and fix the probes 12 with the locking cover 13. This allows the probes 12 and connecting wire 11 to be stored inside the meter body 1, making it convenient for the multimeter to be carried, placed, and used. By winding the connecting wire 11 between the winding posts 8 and fixing the probes 12 with the locking cover 13, the probes 12 and connecting wire 11 can be stored inside the meter body 1, making it convenient for the multimeter to be carried, placed, and used. This avoids contamination during the production of the medicated patches, prevents the multimeter from becoming a carrier of pollutants, and improves the controllability and safety of the multimeter during use.
