Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a multimeter capable of storing and preventing electric shock. Background Art

[0002] In the chemical production process, some control instruments are needed. They can compare the measured signal with the given value, calculate the deviation signal according to certain control rules, and output the operation result as a specified signal, thereby controlling some precise chemical steps in the related chemical production process.

[0003] However, the existing chemical control instruments still have the following problems during use:

[0004] Most of the existing chemical control instruments are relatively precise and usually have protective devices on the outside, otherwise they are easily damaged and affect their use. However, in order to increase the protective effect, the protective devices used in the existing chemical control instruments adopt a more compact structure, which makes installation and disassembly inconvenient and inconvenient for maintenance.

[0005] Therefore, designing a chemical control instrument protection device with good protection effect and convenient disassembly is an urgent problem to be solved.

[0006] A multimeter is a common tool for electricians. It can usually be used to measure multiple parameters such as voltage, resistance and current. Therefore, it is sometimes called a three-purpose meter. It is often used in experiments, installation and maintenance of power equipment, and has a wide range of uses.

[0007] The existing patent CN109828138B discloses a universal measuring instrument for preventing electric shock for power maintenance, including a case and two measuring devices, the measuring device including a storage box and a measuring mechanism, the storage box is provided with cables and a storage mechanism, the storage mechanism includes a translation assembly, a translation plate, a plurality of first sleeves and a plurality of second sleeves, the measuring mechanism includes a driving assembly, an insulating tube and a sealing assembly, the driving assembly includes a first cylinder, a first piston, a first spring, a pressure plate and a connecting rod, the insulating tube is provided with a second cylinder, a second piston and a test lead, the universal measuring instrument for preventing electric shock for power maintenance can conveniently store the cables into the storage box through the storage mechanism to facilitate the arrangement and storage of the equipment, and can also pull the cables out of the storage box for easy measurement and use, not only that, in the measuring mechanism, the electrician holds the insulating tube and presses the pressure plate to make the test lead extend out of the insulating tube for measurement, thereby avoiding electric shock and ensuring the detection accuracy, thereby improving the practicality of the multimeter.

[0008] However, when the above-mentioned testing equipment is in use, although it can ensure that workers do not touch the test leads throughout the process to prevent electric shock, it is necessary to keep pressing the pressure plate during testing to ensure that the test leads remain extended. During long-term testing, it is easy to get tired and the operation is inconvenient, which reduces its applicability. Utility Model Content

[0029] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments:

[0030] See also Figure 1-4 The utility model provides a storage-proof electric shock-proof multimeter, comprising a multimeter body (1), a storage box (11) fixedly provided on both sides of the multimeter body (1), the storage box (11) comprising an insulating box (21) slidably connected to the storage box, a test lead (22) provided in the insulating box, a driving component for moving the test lead, and a sealing component for protecting the test lead;

[0031] The driving component comprises a connecting plate (23) connected to one end of the test lead, a pushing frame (24) connected to the connecting plate, a screw rod (25) connected to one end of the insulating box, a small gear (26) fixedly connected to the outer end of the screw rod (25), a fixing plate (27) fixedly connected to one side of the top of the insulating box (21), a rotating rod (28) connected to the fixing plate (27), a rotating wheel (32) fixedly connected to the inner side of the rotating rod (28), a large gear (29) fixedly connected to the outer side of the rotating rod (28), and a rotating handle (33) fixedly connected to one side of the rotating wheel (32). The pushing frame (25) is connected to one end of the insulating box, and a small gear (26) fixedly connected to the outer end of the screw rod (25) is fixedly connected to the outer side of the insulating box (21). The drive frame (24) passes through the insulating box (21) and is fixedly connected to the connecting plate (23) on the inner side. The screw rod (25) passes through the outer side of the pushing frame (24) and is threadedly connected to the pushing frame (24). The inner end of the screw rod (25) is rotatably connected to the insulating box (21). The small gear (26) and the large gear (29) are meshed. The rotating rod (28) passes through the fixed plate (27) and is rotatably connected to the fixed plate (27). Limiting grooves (30) are respectively provided on both sides of the insulating box (21). Limiting blocks (31) are respectively fixedly provided on both sides of the connecting plate (23). The limiting blocks (31) are slidably connected to the limiting grooves (30).

[0032] The sealing component comprises a through opening (34) opened at the top of the insulating box (21), a sealing plate (35) arranged in the through opening (34), first grooves (36) respectively opened at both sides of the through opening (34), a sliding rod (37) arranged in the first groove (36), a first spring (38) fixedly connected to one end of the sliding rod (37), a buckle portion (39) fixedly connected to the other end of the sliding rod (37), and two buckle grooves (40) respectively opened at both sides of the sealing plate (35), wherein the sliding rod (37) slides with the first groove (36) The buckle portion (39) is slidably connected to the buckle groove (40), a second groove (41) is provided on one side of the slide rod (37), a guide rod (42) is fixedly connected to one side of the first groove (36), one end of the guide rod (42) is fixedly connected to a second spring (43), the other end of the second spring (43) is fixedly connected to the inner wall of the second groove (41), the guide rod (42) is slidably connected to the second groove (41), a pull rod (44) is fixedly connected to the top of the sealing plate (35), and a pull plate (45) is fixedly connected to the top of the pull rod (44).

[0033] When it is necessary to use the test lead 22 for measurement, the pull plate 45 is pulled to drive the sealing plate 35 at the bottom of the pull rod 44 to move upward.

Then, when the sealing plate 35 moves a certain distance, the buckle portion 39 meets another buckle groove 40, and the first spring 38 and the second spring 43 are reset to push the buckle portion 39 into the buckle groove 40 to fix the sealing plate 35. At this time, the rotating handle 33 can be turned to drive the rotating wheel 32 to rotate, and the rotation of the rotating wheel 32 drives the rotating rod 28 to rotate. The rotation drives the large gear 29 to rotate, the rotation of the large gear 29 drives the small gear 26 to rotate, the rotation of the small gear 26 drives the screw 25 to rotate, the rotation of the screw 25 drives the push frame 24 to move, the movement of the push frame 24 pushes the test lead 22 at the other end of the connecting plate 23 to move out of the insulating box 21, and then the test lead 22 can be moved close to the measuring point for measurement. Since the electrician's hand is separated from the test lead 22 during measurement and does not contact the test lead 22, the electrician can be prevented from electric shock and the accuracy of the measurement is guaranteed. When the measurement is completed, the rotating handle 33 is rotated in the opposite direction to move the test lead 22 into the insulating box 21, and then the sealing plate 35 is pushed downward so that the sealing plate 35 seals the insulating box 21.
