Embodiment 1

[0217] This embodiment mainly introduces the movement mechanism of the card block and related usage conditions.

[0218] The block movement mechanism includes a sliding box 31 and a box cover 30 . Wherein, the sliding box 31 comprises a flat box bottom and a raised frame around it, see Figure 22 to Figure 25 ; Figure 22 is the front view of the sliding box; Figure 23 yes Figure 22 A-A sectional view in ; Figure 24 yes Figure 22 rear view of Figure 25 yes Figure 22 B-B direction sectional view in.

[0219] The center of the case bottom of the sliding box 31 offers an avoidance hole, and the avoidance hole is to make room for the top of the impact weight 6 . The middle part on the left side of the sliding box 31 offers a left avoidance gap, and the middle part on the right side of the sliding case 31 offers a right avoidance gap; When the first separation block 27 and the second separation block 28 move towards each other, it is necessary to ensure that a corres...

Embodiment 2

[0230] combine figure 1 , image 3 , Figure 41 , Figure 42 , Figure 43 Be explained. figure 1 is a schematic diagram of the system of the present invention; image 3 yes figure 1 The enlarged image of the lower part, the zoom ratio is 1.5:1; Figure 41 It is a schematic diagram of the structure of the guardrail, base, fixture and drawer; Figure 42 yes Figure 41 change graph, with Figure 41 In contrast, the clamp in this figure is inserted into the tested sample labeled 42; Figure 43 yes Figure 42 top view.

[0231] The test sample 42 is a lithium ion battery. Lithium-ion batteries or other products with shapes such as matchboxes and cigarette boxes all have two parallel surfaces. The clamp in this embodiment can clamp the sample to be tested by clamping the two parallel surfaces. 42, and very conveniently.

[0232] In addition to the above-mentioned lithium-ion batteries, or other samples with two parallel surfaces, the clamp can also hold samples of vari...

Embodiment 3

[0248] In this embodiment, another block movement mechanism is introduced, which is different from the block movement mechanism formed by the sliding box 31 and the box cover 30 .

[0249] combine Figure 44 , Figure 45 with Figure 46 Be explained. Figure 44 It is a structural relationship diagram of the fixing bar, the mounting plate, the spring, the sliding limiting block and the clamping block; Figure 45 It is one of the three-dimensional schematic diagrams of the sliding restriction block whose section is L-shaped; Figure 46 It is the second perspective view of a sliding restriction block whose section is L-shaped. again: Figure 44 The small arrows in indicate the direction of motion of each object.

[0250] In this embodiment, the block movement mechanism includes: No. 1 fixed bar (61), No. 2 fixed bar (62), mounting plate (63), No. 1 sliding limiting block (51), No. 2 sliding limiting block (52 ), No. 3 sliding restriction block (53) and No. 4 sliding restri...

Abstract

The invention relates to the field of detection technologies and discloses a weight impact test system. In order to solving the problem that an impacting weight is interfered by other forces during the process of falling, the technical scheme is provided; and the weight impact test system is characterized in that a weight clamping device comprises a bracket mechanism (4), a first electromagnet (11), a second electromagnet (12), a first separation block (27), a second separation block (28), a first clamping block (25), a second clamping block (26), a first spring group (29-1), a second spring group (29-2) and a clamping block moving mechanism, wherein the bracket mechanism (4) is fixedly connected with a lifting block (22), the clamping block moving mechanism is fixedly connected with the bracket mechanism (4), the first clamping block (25) is in front and rear sliding connection with the clamping block moving mechanism, the second clamping block (26) is in front and rear sliding connection with the clamping block moving mechanism, and the impacting weight (6) is provided with a clamped structure. The weight impact test system has the beneficial effect that the impacting weight is free from being interfered by any other forces during the process of falling.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a heavy object impact test system. Background technique [0002] Under various environments and conditions, safe storage, safe transportation and safe use are the technical performances that many products must possess; for this reason, whether it is the manufacturer or the country's special testing agency, it is necessary to carry out heavy impact on such products Test to detect and verify the technical performance of the product to withstand the impact of heavy objects. In the heavy object impact test, the sample to be tested is often clamped below, and then the impact weight is released above, and the sample is subjected to a heavy object impact test to observe whether the tested sample will explode or burn. In the test, the weight of the impact weight and the height of the impact weight from the tested sample are specified; in particular: the initial speed of the impact wei...
