The top of the gas transmission rod 403 is connected with a reversing valve 409 through a gas pipe 408, then is connected with a detection device through the reversing valve 409, and changes the gas inlet mode through the reversing valve 409, so that the gas tightness detection in the vacuumizing mode and the gas tightness detection in the inflating mode can be realized by matching the detection device, and various working condition requirements are met. The bottom of the gas transmission rod 403 is connected with the gas filling port 401 and is used for being connected with the gas tightness detection hole 11 on the battery pack 10 to be detected.

One end of the extension plate 230 is connected with a connection plate 220, the extension plate 230 is vertically connected with the connection plate 220, and the back of the connection plate 220 is connected with a front plate 210 through a screw; the back of the front plate 210 is provided with a sliding block 211, and the sliding block 211 is slidably connected with a sliding groove 201 arranged at the top of the main plate 200, so that the position of the air transmission device 400 in the X direction can be conveniently adjusted.

The working principle is as follows: when the bottom of the battery pack 10 to be tested is relatively flat, firstly, the battery pack 10 to be tested is placed on the bottom plate 100, two side surfaces of the battery pack 10 to be tested are tightly attached to the flexible positioning components 330 on the transverse plate 310 and the longitudinal plate 320, the bottom of the battery pack 10 to be tested is pressed on the rubber plug 332 on the bottom plate 100 with slight force to adsorb the battery pack 10 to be tested, the two side surfaces can be selectively extruded to adsorb the battery pack 10 to the transverse plate 310 or the longitudinal plate 320 according to conditions, so that flexible positioning is achieved, further, the gas transmission rod 403 is pulled upwards, the gas transmission device 400 is moved to the position above the gas tightness detection hole 11 through the sliding block 211, the gas transmission rod 403 is loosened, the spring 404 presses the gas transmission rod 403 downwards, so that the gas filling port 401 is pressed on the gas tightness detection hole 11, and a sealing effect is achieved. Meanwhile, the downward force applied by the spring can be effectively adjusted in a self-adaptive manner, due to the downward force of the spring, the downward force is further applied above the battery pack 10 to be tested, the bottom of the battery pack 10 to be tested is fixedly supported by the two flexible positioning components 330 positioned on the same straight line, so that the battery pack has the possibility of rotating in the Y direction and the X direction, when the inflation inlet 401 is pressed down, the self-adaptive adjustment is completed, the inflation inlet 401 and the air tightness detection hole 11 are in a flat state relatively, air leakage caused by the fact that creases are bent and the like due to uneven stress of all parts of the inflation inlet 401 during pressing down is avoided, the air tightness effect is effectively improved, the service life of the inflation inlet 401 is prolonged, the flexible positioning components 330 positioned on the same straight line are used for auxiliary support on the side face, the stability of the battery pack 10 to be tested is guaranteed, the battery pack has a certain degree of freedom, and the problems of unevenness, inconvenience in fixation and the like caused by interfaces on different battery packs 10 to be tested can be avoided.

When the bottom of the battery pack 10 to be tested is provided with a groove and cannot be fixed, as shown in fig. 6, the flexible positioning component 330 on the transverse plate 310 serves as the main fixing left and right, the longitudinal plate 320 and the flexible positioning component 330 on the bottom plate 100 serve as the auxiliary positioning, the side surface of the battery pack 10 to be tested is adsorbed on one side of the transverse plate 310 through forced extrusion, when the battery pack 10 to be tested is pressed down under the pressure action of the inflating port 401-shaped spring 404, the battery pack 10 to be tested also has enough freedom to adjust the relative parallel and level of the contact surface of the inflating port 401 and the air tightness detection hole 11, and similarly, the flexible positioning of the battery pack 10 to be tested can be carried out through the plurality of flexible positioning components 330 arranged on the longitudinal plate 320.

In another usage, usually, the flexible positioning member 330 is fixed by the long bolt 340, but when the bottom of the battery pack 10 to be tested is not fixed conveniently and the fixing firmness of only one side of the horizontal plate 310 or the vertical plate 320 is not enough, the flexible positioning member 330 can be fixed on one side of the horizontal plate 310 or the vertical plate 320 by first fixing the horizontal plate 310 or the vertical plate 320, then loosening the long bolt 340 on the other positioning plate, manually pressing the flexible positioning member 330 on the battery pack 10 to be tested for fixing, and then fixing the displacement rod 331 by using the long bolt 340, so that the flexible positioning members 330 on the horizontal plate 310 and the vertical plate 320 are flexibly connected with the battery pack 10 to be tested, but at the same time, the battery pack 10 to be tested still has the freedom of rotation in the X direction and the freedom of rotation in the Y direction after being fixed, and can also meet the requirement of compensating the inclined deformation caused by the pressing of the air charging port 401.

Compare the mould that traditional mode needs to correspond to specific battery and carry on spacingly, spacing back battery package has lost rotatable degree of freedom basically simultaneously, and pass the connection of gas device 400 also is a problem, is difficult to satisfy multiple battery, different shapes, the demand that different gas tightness detected, through utility model's frock can this problem of effectual solution, satisfy the gas tightness detection of different shape products, can carry out the gas tightness detection of evacuation promptly, also can adopt gas filled form to carry out the gas tightness detection.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
