Relative lateral wall all is fixed with a plurality of location strip 5 in the box 1, has eight with one side location strip 5, and two adjacent location strips 5 that correspond on one of them lateral wall and another lateral wall are a set of, and on the same group be inserted between four location strips 5 and be equipped with a tray 2, the length direction of location strip 5 and the length direction of tray 2 the same.

Referring to fig. 1 and 2, a coupling groove 27 is oppositely formed at the bottom surface of the tray 2, the coupling groove 27 has the same length direction as the moving direction of the tray 2, and the coupling groove 27 is adjacent to the positioning bar 5. A connecting plate 25 is hinged to the tray 2 at the connecting groove 27, the connecting plate 25 can be accommodated in the connecting groove 27, and the hinged position of the connecting plate 25 and the tray 2 is far away from the box door 11. The bottom surface of the connecting plate 25 is oppositely connected with a roller 26, a third elastic member is connected between the connecting plate 25 and the tray 2, the third elastic member is specifically a spring, and when the spring is in a compressed state, the spring is vertically arranged and is positioned in the connecting groove 27. The connecting plate 25 tends to move away from the connecting slot 27 by the action of the spring, so that the tray 2 is more firmly connected to the same set of positioning strips 5.

In order to facilitate the sliding of the roller 26, the top surfaces of the two positioning strips 5 located at the lower layer on the same group of positioning strips 5 are provided with positioning grooves 51 arranged along the length direction thereof, and the roller 26 slides on the positioning grooves 51.

The positioning strips 5 on the upper layer on the same group of positioning strips 5 are provided with positioning holes 54, the positioning holes 54 are vertically arranged, the bottom ends of the positioning holes 54 penetrate through the bottom surfaces of the positioning strips 5, and the top ends of the positioning holes 54 do not penetrate through the top surfaces of the positioning strips 5. A positioning rod 52 is slidably inserted into the positioning hole 54, and the length of the positioning rod 52 is smaller than the depth of the positioning hole 54. A fourth elastic member 53 is fitted around the positioning rod 52, one end of the fourth elastic member 53 is fixed to the positioning bar 5, and the other end is fixed to a side wall of the positioning rod 52, and the fourth elastic member 53 is specifically a spring. When the fourth elastic element 53 is in a static state, the end of the positioning rod 52 extends out of the bottom surface of the positioning strip 5; when the tray 2 is inserted between two adjacent positioning strips 5, the top surface of the tray 2 abuts against the bottom surface of the upper positioning strip 5 on the same group of positioning strips 5, so as to push the positioning rod 52 to move towards the positioning hole 54, i.e. the fourth elastic element 53 is in a compressed state, and at this time, a force is applied to make the positioning rod 52 abut against the tray 2.

Set up a plurality of cavities 21 of placing that run through on the tray 2, the area of placing cavity 21 cross section is greater than the area of battery cross section, guarantees that the battery can put into and places the intracavity 21.

Referring to fig. 3, a position corresponding to the placing cavity 21 on the tray 2 is detachably connected with a limiting mechanism 3, and the limiting mechanism 3 includes a U-shaped plate 31, two L-shaped plates 32 and two limiting grooves 33. The size of U-shaped board 31 and place chamber 21 looks adaptation, two L shaped boards 32 rotate to be connected on U-shaped board 31, and U-shaped board 31, two L shaped boards 32 enclose the cavity that holds the battery each other. The vertical section of L-shaped plate 32 is connected on U-shaped plate 31 in a rotating manner, U-shaped plate 31 is connected with first elastic element 34 for limiting the rotating angle of L-shaped plate 32, and first elastic element 34 is specifically a torsion spring, and under the action of the torsion spring, the vertical section of L-shaped plate 32 and the bottom plate of U-shaped plate 31 are in a perpendicular relation. Spacing groove 33 is seted up on tray 2, and spacing groove 33 supplies the horizontal segment of L shaped plate 32 to insert and establishes, when needs connect stop gear 3 on tray 2, thereby presses two L shaped plates 32 through both hands and makes two L shaped plates 32 be close to each other to make stop gear 3 can the adaptation place the size of chamber 21, loosen two L shaped plates 32 when being close to spacing groove 33 and make two L shaped plates 32 insert respectively on the spacing groove 33 that corresponds.

Articulated at the top surface of tray 2 have and be used for the lid to close protection mechanism 4 who places chamber 21, and protection mechanism 4 includes protection shield 41 and two protection pieces 42, and protection shield 41 articulates on tray 2, and this articulated department is located between two L shaped plates 32, and protection piece 42 rotates through the pivot to be connected and is used for compressing tightly protection shield 41 on tray 2, and protection piece 42 is located corresponding spacing groove 33 top.

The position, corresponding to the limiting groove 33, of the tray 2 is provided with a limiting hole 24, the limiting hole 24 is vertically arranged, the top end of the limiting hole 24 penetrates through the top surface of the tray 2, the bottom end of the limiting hole 24 is communicated with the limiting groove 33, and a limiting rod 22 is connected to the limiting hole 24 in a sliding mode. The limiting rod 22 is sleeved with a second elastic piece 23, one end of the second elastic piece 23 is fixed on the tray 2, the other end of the second elastic piece 23 is fixed on the side wall of the limiting rod 22, and the second elastic piece 23 is specifically a spring. When second elastic component 23 does not receive under the external extruded condition, the bottom of gag lever post 22 stretches into spacing groove 33, when L shaped plate 32 inserted the spacing inslot 33, L shaped plate 32 can with gag lever post 22's tip butt to promote gag lever post 22 upward movement, thereby spacing hole 24 is stretched out on the top of gag lever post 22 wears to establish on protection shield 41, nevertheless does not stretch out protection shield 41, should set up and further play spacing effect to protection shield 41.

When the L-shaped plate 32 is inserted into the limit groove 33, in order to facilitate pushing the limit rod 22, a sliding groove 35 for sliding the end of the limit rod 22 is formed in the side wall of the L-shaped plate 32 close to the limit rod 22, the groove bottom of the sliding groove 35 is obliquely arranged, and the groove bottom of the sliding groove 35 is gradually far away from the limit rod 22 along the direction in which the L-shaped plate 32 is inserted into the limit groove 33. When L shaped plate 32 just inserted the spacing inslot 33, gag lever post 22 can at first with the lowest butt of spout 35, along with L shaped plate 32's promotion, gag lever post 22 can slide the highest point of spout 35, this spout 35 actually plays the effect of direction, and when L shaped plate 32 stretched out spacing inslot 33, the gag lever post 22 of being convenient for of this slope stretched into again spacing inslot 33.

Referring to fig. 1, 2 and 3, a method for testing a high temperature resistance test chamber for a battery includes the steps of:
