[0002] Power supply equipment is an indispensable component of electronic equipment, and its performance stability is directly related to the operational reliability of the entire system. Existing power supply testing equipment often requires connecting cables to probes for use in order to better test the power supply path.

[0003] Existing power supply testing equipment suffers from problems such as inconvenient storage of connecting cables and easy damage to the circuits and probes when left lying around. Therefore, a new power supply testing device is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a power supply testing device that solves the problem in the prior art that the connecting wires are inconvenient to store and that the wires and probes are easily damaged if placed randomly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power supply testing device, including a test box, a control panel on the front side of the test box, a rotating shaft rotatably mounted on the top of the control panel, a protective cover rotatably mounted on the outer side of the rotating shaft, a movable shaft mounted on the top of the test box, a take-up reel fixed on the outer side of the movable shaft, a toothed disc mounted on the bottom of the take-up reel, a fixed base fixed on the top of the test box, a spring installed inside the fixed base, a buckle connected to the end of the spring, the buckle engaging with the front side of the toothed disc, a connecting wire inserted into the rear side of the test box, a test pen fixed at the front end of the connecting wire, a limit buckle fixed on the left side of the test box, and a slot formed in the middle of the limit buckle.

[0006] Preferably, the protective cover forms a rotating structure with the control panel via a rotating shaft, and the rotating shaft is made of acrylic material.

[0007] Preferably, the winding reel forms a rotating structure with the test box via a movable shaft, and the winding reel and the toothed disc are integrated.

[0008] Preferably, the middle section of the connecting line extends through the middle of the take-up reel, and the connecting line can be wound around the outside of the take-up reel.

[0009] Preferably, the buckle forms an elastic structure between the spring and the fixed seat, and the gear plate forms an engaging structure between the buckle and the fixed seat.

[0010] Preferably, the detection pen forms an engaging structure with the test box through a limiting buckle, and the slot is symmetrically opened about the central axis of the limiting buckle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a take-up reel, the protective cover can be manually lifted and rotated around the shaft to open during use, exposing the internal control panel for easy power on / off and maintenance. When not in use, the outer protective cover automatically rotates around the shaft to remain closed due to gravity, thus protecting the inner control panel. When the limit buckle is needed for testing, the buckle can be pulled back to make the compression spring slide inward along the inside of the fixing base, separating the buckle from the toothed disc. This allows for convenient operation of the take-up reel to rotate or directly pull the connecting cable, facilitating control of the cable release or rotation for power testing in different locations. Because the toothed disc uses a ratchet design, the winding operation can be performed by directly rotating the take-up reel clockwise, making it more convenient and efficient, effectively protecting and storing the connecting cable.

[0013] 2. By setting a limit buckle, when the test pen is needed, it can be taken out from inside the limit buckle. The test pen can be directly pushed out by the finger through the slot, making it easier and faster to take out from inside the limit buckle. It can effectively store the limit buckle and make the removal operation faster, which is beneficial to the testing operation and also protects the limit buckle. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown in the figure, a power supply testing device includes a test box 1. A control panel 2 is provided on the front side of the test box 1. A rotating shaft 3 is rotatably mounted on the top of the control panel 2. A protective cover 4 is rotatably mounted on the outside of the rotating shaft 3. A movable shaft 5 is installed on the top of the test box 1. A winding reel 6 is fixed on the outside of the movable shaft 5. A toothed disc 7 is installed at the bottom of the winding reel 6. A fixed base 8 is fixed on the top of the test box 1. A spring 9 is installed inside the fixed base 8. A buckle 10 is connected to the end of the spring 9. The buckle 10 engages with the front side of the toothed disc 7. A connecting wire 11 is inserted into the rear side of the test box 1. A test pen 12 is fixed at the front end of the connecting wire 11. A limit buckle 13 is fixed on the left side of the test box 1. A slot 14 is opened in the middle of the limit buckle 13.

[0021] The protective cover 4 forms a rotating structure with the control panel 2 through the rotating shaft 3. The rotating shaft 3 is made of acrylic material. When not in use, the outer protective cover 4 automatically rotates around the rotating shaft 3 due to gravity to keep it in a closed state, thereby protecting the inner control panel 2.

[0022] The winding reel 6 forms a rotating structure with the test box 1 via the movable shaft 5, and the winding reel 6 and the toothed disc 7 are integrated. The toothed disc 7 is equipped with a ratchet. The winding operation can be performed by directly rotating the winding reel 6 clockwise, which is more convenient and efficient, and effectively protects and stores the connecting cable 11.

[0023] The middle section of the connecting wire 11 runs through the middle of the reel 6. The connecting wire 11 can be wound around the outside of the reel 6, which facilitates the control of the connecting wire 11 to be released or rotated for winding, so as to adapt to the power detection use in different positions.

[0024] The buckle 10 forms an elastic structure with the spring 9 and the fixed seat 8, and the toothed disc 7 forms an engaging structure with the fixed seat 8 through the buckle 10. The buckle 10 and the toothed disc 7 are separated from each other, so the winding disc 6 can be easily operated to rotate or the connecting line 11 can be directly pulled, making it convenient to control the connecting line 11 to release or rotate and rewind.

[0025] The detection pen 12 is engaged with the test box 1 through the limit buckle 13, and the slot 14 is symmetrically opened about the central axis of the limit buckle 13. The detection pen 12 can be taken out from inside the limit buckle 13. The detection pen 12 can be directly pushed outward by passing a finger through the slot 14, so that the detection pen 12 can be directly taken out from inside the limit buckle 13.

[0026] Working principle: First, when in use, manually lift the protective cover 4 to rotate it around the pivot 3 to open it, exposing the internal control panel 2 for easy power on / off and maintenance. When not in use, the outer protective cover 4 automatically rotates around the pivot 3 under gravity to remain closed, thus protecting the inner control panel 2. When the limit buckle 13 is needed for testing, pull the buckle 10 backward to squeeze the spring 9 and slide it inward along the inside of the fixed base 8, separating the buckle 10 from the toothed disc 7. This allows for convenient operation of the winding reel 6 to rotate or directly pull the connecting cable 11, facilitating the release or winding of the connecting cable 11 to adapt to power testing in different locations. Since the toothed disc 7 uses a ratchet mechanism, the winding operation can be performed by directly rotating the winding reel 6 clockwise, which is more convenient and efficient, effectively protecting and storing the connecting cable 11.

[0027] Next, when the detection pen 12 is needed, the detection pen 12 is taken out from inside the limit buckle 13. The detection pen 12 can be directly pushed outward by passing a finger through the slot 14, so that the detection pen 12 can be directly taken out from inside the limit buckle 13. This is more convenient and faster. It can effectively store the limit buckle 13 while making the removal operation faster. It is beneficial to the detection operation and also protects the limit buckle 13.
