[0003] However, it is limited by the distance between the fixed clamping end, the movable clamping end and the casing. When the diameter of the battery is large, such as a No. 1 battery, the distance between the fixed clamping end, the movable clamping end and the casing must be increased accordingly so that the electrode plates of the fixed clamping end and the movable clamping end can abut against the battery. This results in the battery testing tooling structure being not compact enough, large in size, and not easy to carry. In addition, it is limited by the positional relationship between the fixed clamping end and the movable clamping end, which makes it impossible to detect batteries with some structures.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0024] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0025] Reference Figures 1 to 6 As shown, a detection device for measuring the battery usage time includes an upper shell 1 and a lower shell 2 that are detachably connected. The bottom surface of the upper shell 1 extends downward and is fixed with a plurality of connecting columns 12. The number of the connecting columns 12 includes but is not limited to four. The four connecting columns 12 are respectively fixed on the four sides of the upper shell 1. A magnet 121 is provided at the bottom of the connecting column 12. The top surface of the lower shell 2 is provided with an adsorption portion 22 adsorbed by the magnet 121. Among them, the first embodiment of setting the adsorption portion 22 is: the top surface of the lower shell 2 can be set to a metal material or a metal layer adsorbed by the magnet 121. The second embodiment of setting the adsorption portion 22 is: another magnet 121 is pre-embedded in the interior of the lower shell 2.

[0026] In another embodiment (not shown), positioning posts can be arranged around the upper shell 1, and positioning grooves that match the positioning posts can be arranged around the lower shell 2, and the upper shell 1 and the lower shell 2 can be detachably connected by the mutual engagement of the positioning posts and the positioning grooves.

[0027] The length of the connecting column 12 constitutes a clearance space 4 between the upper shell 1 and the lower shell 2. A positive electrode plate 11 and a negative electrode plate 21 are fixed between two adjacent end surfaces of the upper shell 1 and the lower shell 2, respectively. The detection circuit board 16 is connected to the positive electrode plate 16 through a wire (not shown in the figure). The positive electrode plate 16 protrudes from the lower end surface of the upper shell 1. The detection circuit board 16 and the negative electrode plate 21 are connected through a conductive connection 3, and the conductive connection 3 extends to the outside of the upper shell 1 and the lower shell 2. The conductive connection 3 is folded and stacked in the clearance space 4 in a bow shape, thereby realizing the storage of the conductive connection 3 and preventing the conductive connection 3 from being entangled with other power cords when the detection device is placed in a storage space such as a backpack or a drawer.

[0028] In order to ensure that the conductive connection 3 is fixed in the clearance space 4, two retractable and movable clamping plates 13 are provided on the upper shell 1. The clamping plates 13 are used to abut the folded surface of the conductive connection 3 so that it is confined in the clearance space 4, and the spacing between the two clamping plates 13 is 3mm to 5mm larger than the cross-sectional width of the conductive connection 3, thereby limiting the lateral movement of the conductive connection 3 through the two clamping plates 13.

[0029] In one specific embodiment, the exposed length of the conductive wire 3 is preferably 80 mm to 100 mm, so that it can be used to detect AA batteries (generally 14 mm in diameter and 49 mm in length), and the redundancy of the wire length is appropriate. When the conductive wire 3 is too long, the user needs to fold the conductive wire 3 multiple times, which is cumbersome; when the conductive wire 3 is too short, it cannot be adapted to the detection of multiple types of batteries.

[0030] A return spring 14 is fixedly disposed inside the upper shell 1 , and is used to retract the wire clamping plate toward the inside of the upper shell 1 , so that the return spring 14 provides a pre-tightening force when the wire clamping plate 13 abuts against the abutting conductive wire 3 .

[0031] A guide post 15 is fixedly disposed inside the upper housing 1. The guide post 15 can be movably inserted into the groove 131 of the clamping plate 13. Figure 4 As shown, the upper end of the reset spring 14 is fixedly sleeved on the guide column 15 by a clamping manner, and the lower end of the reset spring 14 is fixedly connected to the wire clamping plate 13 by a clamping manner.

[0032] The upper end of the wire clamping plate 13 is movably inserted into the interior of the upper housing 1 , and a limiting portion 132 is fixedly disposed on the upper end of the wire clamping plate 13 to prevent the wire clamping plate 13 from being separated from the upper housing 1 .

[0033] The positive electrode plate 11 is fixed to the upper shell 1 and protrudes from the lower end surface of the upper shell 1, and the negative electrode plate 21 is fixed to the lower shell 2 and protrudes from the upper end surface of the lower shell 2. The protruding arrangement facilitates the positive electrode plate 11 to contact the negative electrode plate 21 and the positive and negative electrodes of the battery 5, which is beneficial to the detection of the battery 5. Figure 6 As shown, when the clamping plate 13 is in the retracted position, the clamping plate 13 is retracted into the interior of the upper shell 1 by the return spring 14, and the bottom surface of the positive electrode plate 11 protrudes from the bottom surface of the clamping plate 13, thereby facilitating the detection of the battery 5.

[0034] like Figures 1 to 4 As shown, when the detection device is stored, the upper shell 1 and the lower shell 2 are matched, and the magnet 121 of the connecting column 12 is adsorbed to the lower shell 2, and then the conductive wiring 3 is folded in a bow shape and stacked in the clearance space 4, and the conductive wiring 3 is hidden and placed in the clearance space 4 through the wire clamping plate 13, thereby reducing the space occupied by the detection device and facilitating the storage of the detection device.

[0035] A display panel 17 is fixedly disposed on the top surface of the upper housing 1, and a detection circuit board 16 is also disposed inside the upper housing 1. Figure 5 and 6 As shown, when the detection device is used, the conductive connection 3 is taken out from the clearance space 4, and then the positive electrode plate 11 and the negative electrode plate 21 are respectively in contact with the positive and negative poles of the battery 5, and the detected current is detected and calculated by the detection circuit board 16, and finally the power, voltage and other parameters of the battery 5 are displayed through the display panel 17.

[0036] Among them, a detection circuit board 16 is arranged inside the upper housing 1, and the detection circuit board 16 is connected to the display panel 17 and the positive electrode plate 16 through wires (not shown in the figure), thereby forming an electrically connected loop. The display panel 17 and the detection circuit board 16 are conventional components of the existing battery detection device, and their specific structure and detection principle belong to the existing technology and will not be repeated here.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
