The rear cargo compartment heating shut-off valve is a valve used to control the opening or closing of the cargo compartment heating airway. It has a position indicator device inside to indicate the switch status of the valve. The indicator device consists of a light-emitting diode, a photosensitive transistor and its corresponding control circuit board. When the valve is in a fixed position (open or closed), the parts inside the valve will cover the light-emitting diode at the corresponding position, thereby changing the output signal of the circuit. This signal is fed back to the flight panel to make the corresponding indicator light on to determine the position status of the valve. The test box is connected to the signal circuit of the product externally, including power supply and voltage measurement functions. It can input the working voltage (28VDC) to the signal circuit of the product through a DC power supply, and convert the output signal of the product into a measurable voltage signal to determine the position of the product valve.

[0003] The structure of the existing test box mainly consists of a box body and wires at both ends of the box body. The wires are used to connect the shut-off valve to be tested. The box body is provided with a socket for adapting to the multimeter plug. When in use, the plug is inserted into the socket, and then the position of the shut-off valve is determined according to the voltage and current conditions. However, the wires used for electrical connection in the current test box are relatively long, resulting in a messy circuit after use, which is not conducive to storage and is prone to the problem of wire breaking.

[0004] To this end, the utility model provides a shut-off valve test box device. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a shut-off valve test box device, including a box body 1, a test module is arranged in the box body 1, a test jack 2 is opened on the front of the box body 1, the test jack 2 is a measurement jack for inserting the test lead of a multimeter, and the two ends of the box body 1 are respectively connected to a left test line 3 and a right test line 4. The test box device is externally connected to the line of the signal circuit to be tested. The signal circuit includes power supply and voltage measurement functions. The working voltage (28VDC) can be input to the signal circuit of the product through a DC power supply, and the output signal of the product is converted into a measurable voltage signal, so as to judge the position of the product valve. This part of the line is usually in an exposed state, and is usually set to a longer length for the convenience of external connection. When in use, the left test line 3 and the right test line 4 are connected to the shut-off valve according to the mark. Since this part is a prior art, it will not be described in detail here.

[0023] In the present technical solution, a storage box 5 is fixedly provided at the bottom of the box body 1. The storage box 5 is cube-shaped and is provided with a storage cavity 6 for respectively storing the left test line 3 and the right test line 4. In the specific implementation, it is preferred that a partition 51 is welded at the middle of the storage box 5, and the partition 51 divides the inner cavity of the storage box 5 into two storage cavities 6, so as to solve the problem of the left test line 3 and the right test line 4 being exposed and affecting storage.

[0024] Specifically, a slide seat 7 is slidably connected in the storage chamber 6, and a line-blocking roller 8 is rotatably connected to one side of the slide seat 7. During specific implementation, a support shaft can be welded on one side of the slide seat 7, and then a positioning hole rotatably connected to the support shaft is opened at one end of the line-blocking roller 8. A clearance gap 9 connecting the storage chamber 6 is opened at both ends of the storage box 5, and one storage chamber 6 corresponds to two clearance gaps 9. The line-blocking roller 8 can pass through the clearance gap 9 with a gap. The clearance passing here means that the line-blocking roller 8 can move to the outside of the storage box 5 after passing through one of the clearance gaps 9. When the line-blocking roller 8 is located outside the storage box 5, the adjacent left test line 3 or right test line 4 can bypass the line-blocking roller 8, and then the slide seat 7 corresponding to the line-blocking roller 8 is pulled in the direction away from the left test line 3 or the right test line 4, and the left test line 3 or the right test line 4 will be pulled into the storage chamber 6, and the left test line 3 or the right test line 4 located in the storage chamber 6 is in a U-shaped state. In this way, the left test line 3 or the right test line 4 can be stored and hidden respectively.

[0025] In this embodiment, a slideway 511 is penetrated through the side wall of the partition 51, and a slider 71 that slides with the slideway 511 is welded on the back of the slide seat 7. The sliders 71 on the slide seats 7 in the two storage chambers 6 share a slideway 511. A shift shaft 72 is welded on one side of the slide seat 7. The free end of the shift shaft 72 passes through one side of the box body 1 and the two are slidably arranged. The shift shaft 72 is a handheld component for manually shifting the slide seat 7 to move in the storage chamber 6.

[0026] Furthermore, guide grooves 53 are provided on both sides of the storage box 5, and grooved wheels 721 are provided on the dial shaft 72 to roll with the guide grooves 53. The purpose of this arrangement is to reduce the friction resistance between the dial shaft 72 and the guide grooves 53. That is, when the dial shaft 72 is turned, the grooved wheels 721 will roll in a forward and reverse direction adaptively.

[0027] In this embodiment, a row of L-shaped cards 101 located below the storage cavity 6 is welded to the bottom of the storage box 5, and one storage cavity 6 corresponds to one row of L-shaped cards 101. The function of this part of the L-shaped cards 101 is to store the left test line 3 and / or the right test line 4 exposed in the storage cavity 6. When in use, the left test line 3 and / or the right test line 4 exposed after the storage cavity 6 is stored is bent and inserted between the L-shaped card 101 and the lower surface wall of the storage box 5. Therefore, this arrangement is suitable for the storage operation of the test box with a longer left test line 3 and / or the right test line 4.

[0028] Furthermore, a slot 91 which is respectively engaged with the left test line 3 and the right test line 4 is provided at the bottom of the clearance gap 9. The slot 91 is used to limit the left test line 3 and the right test line 4. When in use, the left test line 3 and the right test line 4 are engaged with the slot 91 to prevent loosening.

[0029] In this embodiment, the outer wall of the wire retaining roller 8 is welded with annular retaining rings 81 at both ends. The function of the annular retaining rings 81 is to prevent the left test line 3 and the right test line 4 from falling off after being wound around the adjacent wire retaining roller 8.

[0030] In this embodiment, a pad 52 is welded to the bottom of the storage box 5 near the corner, and the pad 52 plays a role in supporting the device.

[0031] Working principle: When using this device, connect the left test line 3 and the right test line 4 of the box body 1 according to the mark, turn on the DC power supply to make the product work, and then insert the test lead of the multimeter into the corresponding measuring hole of the test box to read the voltage count of the multimeter. After use, remove the left test line 3 and the right test line 4, and then manually push one end of the dial shaft 72 to push the slide 7 in one of the storage chambers 6, and the line blocking roller 8 on the slide 7 moves toward the opposite direction of the clearance gap 9. When the line blocking roller 8 moves to the outside of the storage box 5, the adjacent right test line 4 or left test line 3 is bypassed from the inside of the line blocking roller 8, and then the corresponding slide 7 is manually reset through the dial shaft 72. At this time, the line blocking roller 8 will passively roll and pull the right test line 4 or the left test line 3 into the corresponding storage chamber 6, and the hidden storage of the current right test line 4 or the left test line 3 is completed. In this way, the other right test line 4 or the left test line 3 can be stored and processed. When it is needed, it is only necessary to manually pull the right test line 4 and the left test line 3 exposed at the clearance gap 9 outwards.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
