Description

Technical Field

[0001] The utility model relates to the technical field of relay testing, in particular to an aging test tooling for a safety relay module. Background Art

[0002] In the prior art, the working principle of the safety relay aging test tooling is generally as follows: put multiple safety relays into the card positions, press the start switch, push the safety relays forward, so that the probes in front of the safety relays are in contact with the terminals of the safety relays. A V-switching power supply is installed inside the tooling to supply power to the meter head and the safety relays. By setting the on-off times and time of the meter head, the safety relays are repeatedly powered on and off, and the aging test of the safety relays can be realized. However, in the use of the existing device, if the tooling does not have a fixing mechanism, during the detection process after the safety relays are placed in the tooling, due to a series of operations such as pressing the switch, it is very likely that the test tooling will move, resulting in the disconnection of the connection between the safety relay and the tooling or the unstable voltage of the electrical connection, thus causing deviation in the test. At this time, an aging test tooling for a safety relay module is needed to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the disadvantages existing in the prior art. In the use of the existing device, if the tooling does not have a fixing mechanism, during the detection process after the safety relays are placed, due to a series of operations such as pressing the switch, it is very likely that the test tooling will move, resulting in the disconnection of the connection between the safety relay and the tooling or the unstable voltage of the electrical connection, thus causing deviation in the test.

[0020] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] As Figures 1-4 shown, the present invention provides a technical solution: a safety relay module aging test tooling, including an outer shell 1, a fixed shell 2 is fixedly installed on the inner wall of the outer shell 1, a plurality of slide holes 4 are opened at the top of the fixed shell 2, the inner wall of the slide hole 4 is slidably connected with a slide plate 5, one side of the slide plate 5 is fixedly connected with a telescopic rod 6, the other end of the telescopic rod 6 is fixedly connected with the inner wall of the fixed shell 2, the top of the slide plate 5 is fixedly connected with a fixed frame 8, one side of the fixed frame 8 is fixedly connected with a baffle 9, a testing mechanism 3 is fixedly installed on the inner wall of the outer shell 1, the top of the testing mechanism 3 is fixedly connected with the top of the fixed shell 2, a first spring 7 is arranged on the outer surface of the telescopic rod 6, one end of the first spring 7 is fixedly connected with one side of the slide plate 5, and the other end of the first spring 7 is fixedly connected with one side of the fixed shell 2. A safety relay 18 is placed on the top of the fixed frame 8, and the output end of the testing mechanism 3 is electrically connected to the interface of the safety relay 18;

[0023] Through the above embodiment, the safety relay 18 can be limited by the fixed frame 8 and the baffle 9, so that the safety relay 18 can be fixed by the fixed frame 8 and the baffle 9. The moving track of the fixed frame 8 can be limited by the slide plate 5 and the slide hole 4, so that the fixed frame 8 is more stable during movement. The template 13 can be fixed by the card hole 17 and the fixed block 14, so that the position of the fixed frame 8 is fixed, and then the safety relay 18 can be fixed to the testing mechanism 3. The first spring 7 can make the fixed frame 8 quickly move away from the testing mechanism 3, which is convenient for taking out the safety relay 18 after testing. The telescopic rod 6 can protect the first spring 7 and increase the service life of the first spring 7;

[0024] Two slide grooves 10 are opened at the top of the baffle 9, and a slide bar 11 is slidably connected to the inner wall of the slide groove 10;

[0025] The bottom end of the sliding rod 11 is fixedly connected with a second spring 12, and the bottom end of the second spring 12 is fixedly connected with the inner ground of the chute 10;

[0026] A template 13 is fixedly connected between the top ends of the two sliding rods 11, and a support plate 16 is fixedly connected to one side of the template 13;

[0027] A plurality of fixing blocks 14 are fixedly connected to the bottom of the template 13, and a pulley 15 is rotatably connected between the sides of two adjacent fixing blocks 14;

[0028] Two card holes 17 are formed in the top of the fixed shell 2, and the inner wall of the card hole 17 is slidably connected with the outer surface of the two fixing blocks 14;

[0029] Through the above embodiments, the template 13 can be controlled through the support plate 16. By controlling the support plate 16 to move upward, the fixing block 14 can be taken out from the inner wall of the card hole 17, and then the fixing frame 8 can be driven to move under the action of the first spring 7, so as to facilitate the removal of the safety relay 18. At the same time, the pulley 15 facilitates the movement of the fixing frame 8. At the same time, during the movement of the fixing frame 8, a damping effect is formed by the second spring 12 and the pulley 15, so that the fixing frame 8 is more stable during the movement. At the same time, the second spring 12 facilitates the sliding of the fixing block 14 into the inside of the card hole 17.

[0030] Working principle:

[0031] As Figures 1-4 shown, the safety relay 18 is placed inside the fixing frame 8, and then the safety relay 18 is made to contact the baffle 9. Then, the template 13 is pushed to move. The movement of the template 13 drives the baffle 9 to move. The movement of the baffle 9 drives the fixing frame 8 to move. The movement of the fixing frame 8 drives the safety relay 18 to contact the testing mechanism 3. At the same time, the movement of the fixing frame 8 drives the sliding plate 5 to move. The movement of the sliding plate 5 will cause the first spring 7 to contract, increasing the elastic potential energy of the first spring 7. At the same time, after the fixing block 14 is aligned with the card hole 17, it will enter the inside of the card hole 17 under the action of the second spring 12, thus completing the fixation of the safety relay 18. Then, by controlling the support plate 16 to move upward, the fixing block 14 can be taken out from the inner wall of the card hole 17, and then the fixing frame 8 can be driven to move under the action of the first spring 7, so as to facilitate the removal of the safety relay 18.

[0032] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
