DETAILED DESCRIPTION

[0019] The technical scheme in the utility model is further explained below in combination with the drawings and embodiments.

[0020] As Figure 1 The utility model discloses an relay check box, including box 1, check appearance 4, conducting ring 7 and closed lid 8, the top opening of box 1 forms installation cavity, and the one side of installation cavity is fixedly provided with first elastic block 2, is set up with a plurality of accommodating groove 3 for relay embedding on first elastic block 2, check appearance 4 is fixedly arranged at the side of installation cavity away from first elastic block 2, and one end of connecting wire 5 is electrically connected with check appearance 4 on check appearance 4, and the other end of connecting wire 5 is electrically connected with spring clamp 6, and conducting ring 7 is electrically connected with the one end of connecting wire 5 away from check appearance 4, and closed lid 8 is hingedly arranged at one end of box 1. The top opening of box 1 forms installation cavity, and the worker carries the device to the predetermined position, preferably, closed lid 8 and box 1 are respectively equipped with lock tongue and lock groove to avoid the arbitrary rotation of closed lid 8, the structure of lock tongue and lock groove can be selected from prior art, check appearance 4 is also selected from existing equipment, and no more is described here, when using, by rotating closed lid 8 and opening installation cavity, the relay to be checked is embedded in the accommodating groove 3 of first elastic block 2, and the terminal of relay is placed to the side of check appearance 4, because first elastic block 2 has elasticity, therefore can adapt to the relay of different size, in the embodiment, two accommodating grooves 3 of big and small are set up on first elastic block 2, then according to the type of relay terminal, the worker can select conducting ring 7 and the terminal of relay to be connected or spring clamp 6 is clamped on the terminal of relay to make connecting wire 5 electrically connected with the terminal of relay and check appearance 4, makes check appearance 4 check and detect the performance of relay, and the device can adapt to the relay of different size through the accommodating groove 3 for embedding relay on first elastic block 2, and the accommodating groove 3 of elastic deformation can adapt to the relay of different size, and spring clamp 6 and conducting ring 7 are electrically connected on connecting wire 5, so that the worker can select the appropriate electrical connection component according to the need to carry out electrical connection check to the relay of different terminal, and the scope of application is wide.

[0021] As Figures 1-3As shown, further, the lifting bar 9 is symmetrically provided with installation slots on the inner wall of the box body 1, and the lifting bar 9 is slidingly arranged between the two installation slots. A plurality of fixing assemblies are slidingly arranged on the lifting bar 9, each of which is used for fixing the conductive ring 7. The top of each fixing assembly is provided with a spring sheet 10. The sidewall of the box body 1 is further provided with a lifting assembly for driving the lifting bar 9 to lift. Specifically, the sliding of the fixing assembly and the lifting bar 9 is frictional sliding. In most cases, workers often check and detect the same type of relays in different places. When checking, the worker first fixes the conductive ring 7 with the fixing assembly, then embeds the first relay to be checked in the accommodating groove 3, adjusts the positions of the plurality of fixing assemblies, so that the spring sheet 10 at the top of the fixing assembly is directly below the terminal of the relay, and then drives the lifting bar 9 to lift through the lifting assembly, so that the spring sheet 10 elastically abuts against the terminal of the relay. The spring sheet 10 is electrically connected with the fixing assembly, and the fixing assembly is electrically connected with the conductive ring 7, so that the checking instrument 4 is electrically connected with the terminal of the relay. After checking the relay, the subsequent same type of relay only needs to be placed in the accommodating groove 3 again, so that the terminal of the relay abuts against the spring sheet 10, and the relay and the checking instrument 4 can be quickly electrically connected, thereby improving the checking efficiency of the relay.

[0022] As shown in Figure 4 Further, each fixing assembly comprises a fixing block 11 which is horizontally slidingly arranged on the lifting bar 9. The spring sheet 10 is fixedly arranged at the top of the fixing block 11. The fixing block 11 is provided with an insertion slot 12. The spring sheet 10 is threadedly connected with a locking screw 13. When connecting the conductive ring 7 with the fixing block 11, the conductive ring 7 is inserted into the insertion slot 12, and then the locking screw 13 is screwed to fix the conductive ring 7 in the insertion slot 12, thereby completing the connection of the conductive ring 7 and the fixing block 11.

[0023] Further, each spring clamp 6 is provided with a channel through which the connecting wire 5 passes. After the connecting wire 5 passes through the channel, the connecting wire 5 is electrically connected with the conductive ring 7. By providing the channel through which the connecting wire 5 passes on the spring clamp 6, the worker can adjust the distance of the conductive ring 7 extending out of the channel according to the needs. When the conductive ring 7 is needed to be used, the conductive ring 7 is pulled out. When the conductive ring 7 is not needed to be used, the spring clamp 6 is used, so that the conductive ring 7 is clamped at the outlet of the channel, thereby avoiding that a plurality of connecting wires 5 and the conductive ring 7 are wound together when not in use.

[0024] As shown in Figure 3As shown, the lifting assembly further includes a lead screw 14, which is vertically and rotatably mounted in the mounting slot. The lead screw 14 is threadedly connected to the lifting bar 9. A motor for driving the lead screw 14 to rotate is also provided on the inner wall of the housing 1. In this embodiment, the motor (not shown in the figure) is embedded in the inner wall of the housing 1. When it is necessary to adjust the height of the lifting bar 9 to accommodate the height difference of relay terminals of different sizes, the motor is started. The motor drives the lead screw 14 to rotate, and the lead screw 14 drives the lifting bar 9, which is threadedly connected to it, to rise or fall along the length of the lead screw 14, thereby accommodating the height difference of the terminals of different relays embedded in the receiving slot 3. Preferably, the lead screw 14 is installed in one of the mounting slots, and a guide rod is vertically provided in the other mounting slot. The guide rod is slidably connected to the lifting bar 9, so that the lifting bar 9 can rise and fall stably.

[0025] like Figures 1-3 As shown, it further includes a second elastic block 15, which is fixedly installed inside the housing 1 and located between the first elastic block 2 and the calibrator 4. The second elastic block 15 is also provided with several receiving slots 3. The receiving slots 3 of the second elastic block 15 can be used to place unused relays or relays that have performance problems and need to be replaced, making them easy to store.

[0026] Furthermore, both the first elastic block 2 and the second elastic block 15 are made of foam. Specifically, in this embodiment, both the first elastic block 2 and the second elastic block 15 are made of foam, preferably polystyrene, which has a certain degree of elasticity and can also serve to clamp and fix the relay.

[0027] like Figures 1-3 As shown, it further includes a handle 16, which is fixedly mounted on the side wall of the housing 1. The handle 16 allows workers to easily grip the housing and lift it to various calibration positions.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
