Technical Field

[0001] The utility model relates to the technical field of battery voltage testing, and in particular to a battery voltage testing device. Background Art

[0002] Batteries are the energy source for many devices, including electric vehicles, energy storage systems, and portable electronic devices. Voltage testing can help identify battery failures early, making battery voltage testing an important part of the battery testing process. By testing the battery voltage, key performance indicators of the battery can be obtained, such as capacity, energy density, internal resistance, etc., which is crucial to verifying whether the battery meets the indicators.

[0003] At present, the battery voltage detection method is to observe the battery voltage after connecting the positive and negative electrodes to the detection equipment. The battery detection results can be intuitively perceived through the voltage data. However, when testing a large number of batteries, it is necessary to manually and repeatedly calibrate the detection equipment with the positive and negative electrodes of the battery to complete the detection. After working for a long time, due to the overall inconvenience of operation, the staff will lose physical strength, which will lead to reduced work efficiency.

[0004] Therefore, in view of the above problems, there is an urgent need for a battery voltage testing device that is convenient for detection operation. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a battery voltage testing device which is easy to detect and operate.

Sliding frames are slidably arranged on both sides of the mounting frame, and a voltmeter is arranged on the mounting frame. Contact rods are arranged at the bottom of the two sliding frames, and the two contact rods are connected to the voltmeter through wires. A bidirectional threaded rod is rotatably arranged between the two sides of the mounting frame, and the bidirectional threaded rod passes through the two sliding frames. The three are threadedly matched, and a twist block is rotatably arranged in the middle of the bidirectional threaded rod.

[0007] Optionally, it also includes a sliding rod, a card plate and an elastic member. A plurality of grooves are evenly spaced on the surface of the twist block, and two sliding rods are slidably arranged through the middle of the mounting frame. A card plate is arranged between the two sliding rods. The card plate is snap-fitted with the grooves, and elastic members are arranged between the top sides of the card plate and the mounting frame, and the two elastic members pass through adjacent sliding rods.

[0008] Optionally, a rotating shaft and a protective frame are also included. The rear lower sides of the two sliding frames are each provided with a rotating shaft, and the protective frame is rotatably provided on the two rotating shafts.

[0009] Optionally, a magnet is also included. The outward side of the two sliding frames is provided with a magnet, and the magnet is magnetically matched with the adjacent protective frame.

[0010] Optionally, a T-shaped rod is further included, and the bottom of the two contact rods is provided with a T-shaped rod.

[0011] Optionally, a wire binding plate is further included, and a plurality of wire binding plates are arranged at intervals on the inner side of the two sliding frames.

[0012] Optionally, a holding block is further included, and the holding block is arranged on the top of the mounting frame.

[0013] The utility model has the following advantages: 1. The utility model rotates the bidirectional threaded rod by a screw block, thereby adjusting the position between the two sliding frames, and the position of the contact rod is adjusted accordingly, making the overall operation more convenient, and at the same time, the holding of the mounting frame can be more convenient for the staff to detect and operate, thereby achieving the effect of easy operation;

[0014] 2. The utility model fixes the position of the screw block by means of a clamping plate, so that the position of the screw block is not easy to rotate and tilt, thereby avoiding position deviation and fixing the position of the sliding frame at the same time;

[0021] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0022] Embodiment: A battery voltage testing device, such as Figure 1-Figure 4 As shown, it includes a mounting frame 1, a sliding frame 2, a voltmeter 3, a contact rod 4, a bidirectional threaded rod 5 and a twist block 51. The sliding frames 2 are slidably arranged on the left and right sides of the mounting frame 1, and the two cooperate to form a support frame that is more convenient for users to hold. The two sliding frames 2 are arranged in opposite directions to form a space for adjusting the distance between them. The voltmeter 3 is fixedly arranged at the front center position of the mounting frame 1, and the bottoms of the two sliding frames 2 are respectively provided with contact rods 4, which are used for contacting the electrodes. The two contact rods 4 are connected to the voltmeter 3 through wires, so that the voltage data of the electrodes are transmitted to the voltmeter 3 through the contact rods 4, and a bidirectional threaded rod 5 is rotatably arranged between the left and right sides of the mounting frame 1. The bidirectional threaded rod 5 passes through the two sliding frames 2, and the three are threadedly matched, and a twist block 51 is rotatably arranged in the middle of the bidirectional threaded rod 5, and the bidirectional threaded rod 5 can be twisted by the twist block 51, so that it can be more convenient to adjust the position of the sliding frame 2 and the contact rod 4.

[0023] like Figure 3 As shown, it also includes a sliding rod 7, a clamping plate 8 and an elastic member 9. Eight grooves 6 are evenly spaced on the surface of the twisting block 51, and two sliding rods 7 are slidably arranged through the middle of the mounting frame 1. A clamping plate 8 is arranged between the two sliding rods 7. The clamping plate 8 is clamped in the groove 6. The clamping plate 8 can fix the position of the twisting block 51, thereby stabilizing the overall torsional position and avoiding position deviation. Elastic members 9 are arranged between the left and right sides of the top of the clamping plate 8 and the mounting frame 1. The elastic members 9 are springs, and the two elastic members 9 pass through adjacent sliding rods 7.

[0024] like Figure 4 As shown, it also includes a rotating shaft 10 and a protective frame 11. The rotating shaft 10 is set on the lower side of the rear of the two sliding frames 2, and the protective frame 11 is rotatably set on the two rotating shafts 10. The top of the protective frame 11 is in a wrapped frame shape, which can provide surrounding protection for the contact rod 4.

[0025] like Figure 4 As shown, a magnet 12 is also included. The two sliding frames 2 are each provided with a magnet 12 on the outward side. The magnet 12 cooperates with the adjacent protective frame 11 by magnetic attraction, and can fix the position of the installed protective frame 11.

[0026] like Figure 2 As shown, a T-shaped rod 13 is also included. The bottom of the two contact rods 4 is provided with a T-shaped rod 13. The T-shaped rod 13 can increase the contact area of ​​the contact rod 4, thereby enhancing the overall use experience.

[0027] like Figure 2 As shown, a wire harness plate 14 is also included. Two wire harness plates 14 are spaced apart on the inner side of the two sliding frames 2. The wire harness plates 14 can store the wires on the voltmeter 3 to avoid confusion of the lines.

[0028] like Figure 2 As shown, a gripping block 15 is also included. The gripping block 15 is arranged at the top center of the mounting frame 1. The edges and corners of the gripping block 15 are arranged as guide feet, which can improve the comfort during operation.

[0029] When it is necessary to detect the battery voltage, the staff member holds the mounting frame 1, and the holding block 15 protects the staff member's palm, and then turns the screw block 51. As the screw block 51 rotates, the bidirectional threaded rod 5 rotates accordingly, and the two sliding frames 2 also slide left or right on the bidirectional threaded rod 5 as they rotate, so as to adjust the spacing between the two sliding frames 2. The movement of the sliding frame 2 will drive the contact rod 4 connected thereto to move accordingly, thereby achieving the detection effect of batteries with electrodes of different spacings. After the adjustment is completed, the card plate 8 can be moved. The card plate 8 is subjected to force and drives the sliding rod 7 connected thereto to move upward, and the elastic member 9 is deformed accordingly, and then the card plate 8 is pushed back downward to move the card plate 8 is inserted into the groove 6, and the position of the screw block 51 is fixed by it, so as to stabilize the position of the sliding frame 2 and the contact rod 4. At the same time, the wire harness plate 14 limits the wires on the voltmeter 3 to avoid line disorder. Then the staff can complete the battery voltage detection through the contact rod 4 and the voltmeter 3. When the device is not needed, the protective frame 11 can be rotated and laid down to make the protective frame 11 detached from the magnet 12. The outer contour of the contact rod 4 is wrapped and protected by the protective frame 11 to avoid contact damage. At the same time, if a battery that is difficult to detect is encountered, the staff installs a T-shaped rod 13 at the contact rod 4 to increase its contact area with the electrode and improve the convenience of operation.

[0030] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
