DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0028] Example:

[0029] like Figures 1 to 5 As shown, a high-voltage tester for a blade battery is provided, comprising a cabinet 1, a support seat 9 is arranged at the inner center of the cabinet 1, and a clamping assembly 8 for fixing the blade battery is installed on the upper side of the support seat 9; a rib plate 11 is fixedly installed between the front side of the support seat 9 and the side wall of the cabinet 1, an operation port is opened on the top of the cabinet 1, an arc cover 5 is rotatably installed in the operation port through a bearing seat, a buffer assembly 7 is installed inside the arc cover 5, the buffer assembly 7 is used to buffer the high-pressure gas generated when the blade battery is damaged to prevent the arc cover 5 from being damaged, a locking assembly 3 for locking the arc cover 5 is installed on the front side of the cabinet 1, the locking assembly 3 cannot be turned over when locking the arc cover 5, on the contrary, the arc cover 5 can be turned over when the locking assembly 3 is opened, and the rib plate 11 is used to support the support seat 9 without affecting the flipping range and movement of the arc cover 5.

[0030] Specifically, the arc cover 5 is a cover body formed by welding an arc plate and two large fan-shaped plates; Figure 3As shown, the buffer assembly 7 includes a baffle 71, a rubber airbag 72 and a deflation pipe 73. The baffle 71 is provided on the inner side of the arc plate and the large fan plate. The arc plate, the large fan plate and the baffle 71 are connected by rubber airbags 72 respectively. The end of the rubber airbag 72 away from the baffle 71 is connected to the deflation pipe 73, and the deflation pipe 73 runs through the arc cover 5. The pressure acting on the baffle 71 can squeeze the rubber airbag 72, and each rubber airbag 72 has only one deflation pipe 73, which can offset the force on the baffle 71 by slowly exhausting the air. When the force disappears, the rubber airbag 72 can be inhaled and reset by its own elasticity.

[0031] Specifically, Figure 2 As shown, the baffle 71 on the inner side of the arc plate is composed of multiple arc-shaped pieces, so that the baffle 71 can move radially while maintaining the protective function; the baffle 71 on the inner side of the large fan-shaped plate is also a matching large fan-shaped plate, and the overall baffle 71 can meet the functions of axial movement and protection.

[0032] Specifically, Figure 2 and Figure 4 As shown, the locking assembly 3 includes a guide box 31, a first handle 32, a slider 34 and an insert plate 35; a pair of guide boxes 31 are fixedly installed on the front side of the cabinet 1, and sliders 34 are slidably installed inside the guide boxes 31. The sliders 34 are cubes, and the first handles 32 are fixedly installed between the sliders 34. The insert plate 35 is fixedly installed on the rear side of the first handle 32. A through groove is opened on the front side of the cabinet 1, and a slot is opened on the front side of the arc cover 5. The insert plate 35 passes through the through groove and is plugged and assembled with the slot. The number of the insert plates 35 is 1 to 3, and correspondingly, the through grooves and the slots are matched; pulling the first handle 32 can drive the slider 34 to move along the guide box 31, and at the same time move the insert plate 35 horizontally. When the insert plate 35 is separated from the slot, the arc cover 5 can be flipped, and when the insert plate 35 is plugged with the slot, the arc cover 5 is locked.

[0033] Furthermore, an elastic member 33 is installed between the front side of the slider 34 and the side wall of the guide box 31. The elastic member 33 is preferably a cylindrical coil spring, so that the slider 34 drives the first handle 32 and the plug plate 35 to move backward, which is convenient for the plug-in operation and can also prevent the plug plate 35 from loosening and falling off after plugging.

[0034] like Figure 5As shown, the clamping assembly 8 includes a connecting rod handle 81, an adapter block 82 and a blade battery seat 83; the connecting rod handle 81 is an existing component with a connecting rod mechanism, a handle and other structures, which can realize the up and down movement and locking functions. The upper surface of the support seat 9 is fixedly installed with the connecting rod handle 81 and the blade battery seat 83 by screw connection. The movable end of the connecting rod handle 81 is fixedly installed with the adapter block 82, which is installed by screw connection and can be replaced according to the model of the blade battery. The adapter block 82 is located above the blade battery seat 83; the blade battery seat 83 is a seat body with a U-shaped placement groove, which can also be replaced according to the model of the blade battery. When in use, the blade battery is placed in the U-shaped placement groove of the blade battery seat 83, and the adapter block 82 can be moved down by the connecting rod handle 81 to press and fix the blade battery.

[0035] Specifically, a transverse partition 2 is fixedly installed inside the cabinet 1, and the transverse partition 2 divides the interior of the cabinet 1 to form an upper working chamber and a lower storage chamber; when the arc cover 5 is closed and locked, a sealed space is formed inside the working chamber to isolate the high voltage generated when the blade battery is damaged. The cabinet 1 has a cabinet door hinged on the side wall corresponding to the storage chamber, and the formed storage space can be used to place tools, parts, etc.

[0036] A pressure relief valve 10 and a sealing joint are installed on the side wall of the cabinet 1, and the pressure relief valve 10 and the sealing joint are connected to the working chamber; the pressure relief valve 10 can release pressure to the outside when a high-pressure environment is generated inside the working chamber, and the sealing joint is used to pass the wires of the matching blade battery.

[0037] Specifically, the upper edge of the rib plate 11 abuts against the front end of the arc plate when the arc cover 5 is closed, and the lower edge of the rib plate 11 abuts against the rear end of the arc plate when the arc cover 5 is opened; the rib plate 11 has the function of limiting the flipping angle of the arc cover 5, so that the arc cover 5 can be moved into place accurately and quickly when opening and closing.

[0038] Furthermore, a second handle 4 is fixedly mounted on the front side of the arc-shaped cover 5 , and the convenience of flipping the arc-shaped cover 5 can be improved through the second handle 4 .

[0039] A switch 6 is installed on one side of the upper surface of the cabinet 1. The end of the wire entering the working chamber through the sealed joint has two wiring clamps connected to the blade battery. The end of the wire located outside the working chamber is electrically connected to the external power supply through the switch 6. This wire and the wiring clamp can be replaced according to the blade battery model. Therefore, the switch 6 can be used to control whether the blade battery is powered or adjust the power supply voltage.

[0040] The working method of this embodiment is as follows:

[0041] First, pull the first handle 32 outward to separate the plug plate 35 from the slot, and flip the arc cover 5 backward through the second handle 4 until the rear end of the arc cover 5 abuts against the lower edge of the rib plate 11, exposing the clamping assembly 8. Place the blade battery to be tested in the blade battery seat 83 and move the adapter block 82 downward through the connecting rod handle 81 to lock the blade battery, and connect the wire clamp to the blade battery.

[0042] Then, the arc cover 5 is flipped forward by the second handle 4 until the front end of the arc cover 5 abuts against the upper edge of the rib plate 11, and then the reset plug 35 is plugged into the slot to lock the arc cover 5, and the blade battery is gradually connected to a larger voltage through the switch 6 for testing;

[0043] If a blade battery is damaged during the test process, the high-voltage impact generated will be buffered and absorbed by the buffer component 7, and the pressure will be gradually released through the pressure relief valve 10 to ensure the safety of the working environment.
