However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0030] like Figures 1 to 4 The image shows a preferred embodiment of the impact testing device of this utility model. The impact testing device includes a support frame 1, an impact member 2, and a locking member 3.

[0031] The support frame 1 includes a platform 11 and support legs 12 supported on the bottom of the platform 11. Specifically, a first through hole 111 is vertically oriented through the center of the platform 11, and a second through hole 112 communicating with the first through hole 111 is oriented laterally on the side of the platform 11. Multiple support legs 12 are arranged circumferentially around the outer periphery of the impact member 2.

[0032] The impact member 2 is movably mounted on the support frame 1. In this embodiment, the impact member 2 includes a movable rod 21 extending vertically, an impact block 22 connected to the bottom end of the movable rod 21, and a handle 23 connected to the top end of the movable rod 21. Specifically, the movable rod 21 is movably inserted into the first through hole 111, and a plurality of limiting grooves 211 arranged sequentially in the vertical direction are provided on the side of the movable rod 21; the impact block 22 has a hollow interior forming a receiving cavity 221 for accommodating sand, and a sand filling port 222 communicating with the receiving cavity 221 is provided on the top wall of the impact block 22.

[0033] Locking member 3 is mounted on support frame 1 and is used to lock impact member 2 in the energy storage position. In this embodiment, locking member 3 includes a limiting rod 31 extending in the left-right direction and an operating post 32 connected to the tail of limiting rod 31. Specifically, limiting rod 31 is movably inserted into second through hole 112. In the locked state, the head of limiting rod 31 is inserted into limiting groove 211; in the unlocked state, the head of limiting rod 31 is disengaged from limiting groove 211.

[0034] With the impact component 2 in the energy storage position unlocked by the locking component 3, the impact component 2 falls vertically to the impact position under its own weight. On the one hand, this avoids the impact of different operator techniques and forces on the test results. On the other hand, the impact component 2 falls vertically without any tilt angle, which can ensure the accuracy of the test.

[0035] In addition, such as Figure 4 As shown, when the impactor 2 is lowered to its limit position, the handle 23 abuts against the table 11. The handle 23 has the following functions: first, it makes it convenient for the operator to lift the impactor 2; second, it can prevent the impactor 2 from falling off the support frame 1; and third, it can prevent the impactor 2 from falling and damaging the ground due to operator misoperation.

[0036] The working principle of this embodiment is as follows:

[0037] (1) Before testing, first fill the receiving cavity 221 with sand through the sand filling port 222 until the total weight of the impact component 2 reaches the requirement. Then, lift the impact component 2 to the appropriate position using the handle 23. Finally, insert the head of the limiting pin 31 into the limiting groove 211 of the corresponding height using the operating pin 32 to lock it in place. At this time, if Figure 3As shown, the impact member 2 is locked in the energy storage position by the locking member 3;

[0038] (2) During the test, the induction cooker panel is first placed flat under the impact component 2. Then, the head of the limiting column 31 is disengaged from the limiting groove 211 by the operating column 32 to unlock it. The impact component 2 will fall vertically to the impact position under its own weight to conduct an impact test on the induction cooker panel.
