Description

Technical Field

[0001] The present invention relates to the technical field of test tooling, and in particular to a test tooling for electrical equipment in a workshop. Background Art

[0002] In the field of modern workshop production, there is a large number and various types of electrical equipment, which are the key to ensuring the efficient operation of the production line. However, with the improvement of equipment complexity and the increasingly stringent requirements for precision in production processes, traditional simple test methods are difficult to meet the needs. In the past, relying on manual experience to judge the performance of electrical equipment, lacking accurate data support, it is extremely easy to cause misjudgment, resulting in problem equipment flowing into the production line, causing many disadvantages such as unstable product quality and production interruption. At the same time, unsafe test operations frequently cause accidents such as electric shock and equipment damage, bringing huge economic losses and safety hazards to the workshop. Therefore, the test tooling is an indispensable equipment for inspecting electrical equipment in the workshop.

[0003] Existing test tooling usually has terminal blocks for connecting with electrical equipment. However, after the terminals are connected to the cables, there is no limit for the cables. Due to the complex and changeable workshop environment and the frequent movement of workshop personnel, when workers accidentally touch the unconstrained cables during the execution of tasks, it is easy to cause the cables to break away from the terminals, which will not only cause the electrical equipment being tested to suddenly lose power, affecting the test process, but also may cause instantaneous voltage and current impacts on the equipment, damaging the internal electronic components of the equipment and bringing irreversible damage to the equipment. In view of this, this application proposes a test tooling for electrical equipment in a workshop. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a test tooling for electrical equipment in a workshop.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A test tooling for electrical equipment in a workshop includes a test box. A plurality of terminals are symmetrically installed on the top surface of the test box. A plurality of protection tubes are fixedly connected and communicated with the side surface of the test box. A plurality of cables are connected to each terminal, and each cable passes through the protection tube and extends outwards. An annular airbag is installed in each protection tube. An air injection box is fixedly installed on the top surface of the test box. An air injection mechanism is provided in the air injection box, and each annular airbag is communicated with the air injection mechanism. An auxiliary ring is slidably connected to the outside of each protection tube. The test box drives each auxiliary ring to slide outwards through a moving mechanism, and each cable passes through the corresponding auxiliary ring.

[0007] Preferably, the gas injection mechanism includes a pressing plate which is slidably connected in the gas injection box. The top surface of the gas injection box is threadedly connected with a first threaded rod, and the bottom end of the first threaded rod is rotatably connected to the top surface of the pressing plate. An air injection airbag is fixedly installed on the bottom wall of the gas injection box, and the air injection airbag is communicated with each annular airbag through a connecting pipe.

[0008] Preferably, the moving mechanism includes a plurality of moving rings, and each moving ring is slidably connected to the outside of the corresponding protective tube. A connecting plate is commonly installed on the plurality of moving rings. A second threaded rod is rotatably connected to the outside of the test box, and the second threaded rod is threadedly connected to the connecting plate. Two sliding rods are symmetrically installed on the side surface of each moving ring, and the other end of each sliding rod is fixedly connected to the side surface of the corresponding auxiliary ring.

[0009] Preferably, a baffle is fixedly installed on the outside of one end of each protective tube away from the test box. Two through holes are symmetrically formed in each baffle, and each sliding rod is slidably connected in the corresponding through hole.

[0010] Preferably, a first knob is installed at the top end of the first threaded rod, and a second knob is installed at one end of the second threaded rod.

[0011] Preferably, an insulating cover is rotatably connected to the top surface of the test box.

[0012] The present invention has the following beneficial effects:

[0013] 1. Through devices such as the gas injection mechanism, annular airbags, terminals, cables, and protective tubes, the present invention realizes that the cable passes through a plurality of protective tubes. The protective tubes can provide protection for the cable and prevent the cables from being wound and knotted with each other. At the same time, through the gas injection mechanism, each annular airbag can be inflated to effectively clamp and limit each cable, so that the cable is not easily pulled by the outside world, resulting in the cable being separated from the terminal, thereby ensuring the normal progress of the test process.

[0014] 2. Through devices such as the moving mechanism and auxiliary rings, the present invention realizes that the sliding position of the auxiliary ring can be changed through the moving mechanism, so that the position where the auxiliary ring supports the cable can be changed, thereby preventing the connection between the cable and the terminal from becoming loose due to the self - weight of the cable.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] The technical solution provided by the present invention is as follows: As Figures 1-3 shown, a test tooling for electrical equipment in a workshop includes a test box 1. A plurality of terminals 3 are symmetrically installed on the top surface of the test box 1. A plurality of protection tubes 5 are fixedly connected and communicated with the side surface of the test box 1. A plurality of cables 4 are connected to each terminal 3, and each cable 4 passes through the protection tube 5 and extends outward. An annular airbag 12 is installed in each protection tube 5. An air injection box 6 is fixedly installed on the top surface of the test box 1. An air injection mechanism is provided in the air injection box 6, and each annular airbag 12 is communicated with the air injection mechanism. By injecting air into each annular airbag 12 through the air injection mechanism, each annular airbag 12 can be inflated to clamp the cable 4 in each direction, so that the cable 4 is not easily detached from the terminal 3, thereby ensuring the normal progress of the test process. An auxiliary ring 18 is slidably connected to the outside of each protection tube 5. The test box 1 drives each auxiliary ring 18 to slide outward through a moving mechanism, and each cable 4 passes through the auxiliary ring 18 corresponding to its position. The arrangement of the auxiliary ring 18 and the protection tube 5 can avoid the phenomenon of entanglement and knotting of multiple cables 4, and as the auxiliary ring 18 slides, the position where the bottom of the cable 4 is lifted can be extended, thereby avoiding the situation that the cable 4 is pulled at the connection between the cable 4 and the terminal 3 due to its own gravity, resulting in loosening or even detachment of the connection between the cable 4 and the terminal 3.

[0021] Furthermore, the air injection mechanism includes a pressing plate 9, and the pressing plate 9 is slidably connected in the air injection box 6. The top surface of the air injection box 6 is threadedly connected with a first threaded rod 7, and the bottom end of the first threaded rod 7 is rotatably connected to the top surface of the pressing plate 9. An air injection airbag 10 is fixedly installed on the bottom wall of the air injection box 6. The air injection airbag 10 is communicated with each annular airbag 12 through a connecting pipe 11. By rotating the first threaded rod 7, the pressing plate 9 can slide downward to squeeze the air injection airbag 10. At the same time, a square cavity is opened in the air injection box 6, and the pressing plate 9 is slidably connected in the square cavity, so as to limit the pressing plate 9 and prevent it from rotating.

[0022] Further, the moving mechanism includes a plurality of moving rings 16, and each moving ring 16 is slidably connected to the outer side of the corresponding protective tube 5. A connecting plate 15 is commonly installed on the plurality of moving rings 16. A second threaded rod 19 is rotatably connected to the outer side of the test box 1, and the second threaded rod 19 is threadedly connected to the connecting plate 15. Two sliding rods 17 are symmetrically installed on the side surface of each moving ring 16, and the other end of each sliding rod 17 is fixedly connected to the side surface of the corresponding auxiliary ring 18. By rotating the second threaded rod 19, the connecting plate 15 can be adjusted to slide, so as to drive each moving ring 16 to slide.

[0023] Further, a baffle 13 is fixedly installed on the outer side of each end of the protective tube 5 away from the test box 1. Two through holes 14 are symmetrically formed in each baffle 13, and each sliding rod 17 is slidably connected in the corresponding through hole 14. The through holes 14 can provide a guiding and limiting function for the moving ring 16 and the sliding rod 17, so as to prevent the moving ring 16 from detaching from the protective tube 5.

[0024] Further, a first knob 8 is installed at the top end of the first threaded rod 7, and a second knob 20 is installed at one end of the second threaded rod 19.

[0025] Further, an insulating cover 2 is rotatably connected to the top surface of the test box 1, which can effectively prevent external dust and other impurities from entering the connection between the terminal 3 and the cable 4.

[0026] The present invention provides a test tool for workshop electrical equipment, and the specific working principle is as follows: When it is necessary to test the workshop electrical equipment, first open the insulating cover 2, then pass the cable 4 of the external electrical equipment through each protective tube 5 and connect it to the terminal 3. Then, after each cable 4 is connected, close the insulating cover 2 to provide a relatively sealed environment for the terminal 3, so as to reduce the entry of external dust and other impurities into the connection between the terminal 3 and the cable 4;

[0027] Then turn the first knob 8 to drive the first threaded rod 7 to rotate, so as to drive the pressing plate 9 to slide downward and squeeze the air injection airbag 10, so that the air in the air injection airbag 10 is squeezed into the connecting pipe 11, and through the distribution of the connecting pipe 11, the air flows to each annular airbag 12, prompting each annular airbag 12 to expand and squeeze and fix each cable 4, so as to effectively limit each cable 4 and prevent the cable 4 from easily detaching from the terminal 3, ensuring the normal progress of the test process;

[0028] Meanwhile, the second knob 20 can be turned to drive the rotation of the second threaded rod 19, thereby driving the connecting plate 15 to slide outwards, and driving each moving ring 16 and the sliding rod 17 to slide outwards through the connecting plate 15, so as to change the lifting position of the auxiliary ring 18 on the cable 4, avoiding the loosening of the cable 4 from the terminal 3 caused by the pulling of the cable 4 due to its own gravity. After the adjustment is completed, the power supply can be started to test the electrical equipment in the workshop.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
