BACKGROUND

1. Technical Field

The present disclosure relates to testing apparatuses, and more particularly to a drop test apparatus for a product.

2. Description of Related Art

In a drop test for a product, the product is usually placed on a holding board, and a blocking board is provided to support the tested product when the tested product is dropped. Usually, a distance between the holding board and the blocking board is constant. Therefore, there is room for improvement in the art.

DETAILED DESCRIPTION

FIG. 1illustrates a drop test apparatus in accordance with an embodiment, which comprises a frame100, a first blocking board10, and a second blocking board20.

The frame100comprises a base board101, a support board102, and a holding board103. The support board102is secured to the base board101, and the holding board103is secured to the support board102above the base board101. The base board101is substantially parallel to the holding board103, and the support board102is substantially perpendicular to the base board101and the holding board103. The holding board103is configured to place a tested product.

FIGS. 1 and 2show that the first blocking board10comprises a first mounting end11and a second mounting end12, opposite to the first mounting end11. The first blocking board10defines two first pivot holes112in two opposite sides of the first mounting end11. The first blocking board10further comprises a first top surface13and a first bottom surface15, opposite to the first top surface13. The first top surface13is configured to support the tested product drop from the holding board103. The first bottom surface15defines a plurality of locking slots16. Each of the plurality of locking slots16comprises a guiding surface161and a locking surface163extending from the guiding surface161. The guiding surface161of each of the plurality of locking slots16is slanted relative to the first bottom surface15, and a plurality of protrusions (not shown) protrude from the guiding surface161. The locking surface163of each of the plurality of locking slots16may be an arc-shaped surface. In an embodiment, the locking surface163of each of the plurality of locking slots16is semicircular surface.

The second blocking board20comprises a first securing end21and a second securing end22opposite to the first securing end21. The second blocking board20defines two second pivot holes211in opposite sides of the first securing end21. The second blocking board20further comprises a first upper surface23and a first low surface25, opposite to the first upper surface23. The first upper surface23defines a plurality of latching slots26. Each of the plurality of latching slots26comprises a directing surface261and a receiving surface263extending from the directing surface261. The directing surface261of each of the latching slots26is slanted relative to the first upper surface23, and a plurality of projections2611protrudes from the receiving surface263. The receiving surface263of each of the plurality of latching slots26may be an arc-shaped surface. In the embodiment, the receiving surface263of each of the plurality of latching slots26is semicircular surface.

The drop test apparatus further comprises two first pivot poles30, two second pivot poles50, a first positioning shaft60, and a second positioning shaft70.

One end of each of the two first pivot poles30defines a first through hole31, and a first mounting post33is located on an opposite end. A first installing hole (not labeled) is defined in a center of each of the two first pivot poles30. One end of each of the two second pivot poles50defines a second through hole51, and a second mounting post53is located on an opposite end. A second installing hole (not labeled) is defined in a center of each of the two second pivot poles50.

In an embodiment, a cross section of each of the first positioning shaft60and the second positioning shaft70is circular. A diameter of the first positioning shaft60is equal to or slightly less than that of the first locking surface163, and a diameter of the second positioning shaft70is equal to or slightly less than that of the receiving surface263.

FIGS. 3 to 5show that in assembly, the second blocking board20is secured to the base board101by any known means, such as by screws. A fixing pin40extends into the first installing hole of each of the two first pivot poles30and the second installing hole of each of the two second pivot poles50, to secure the two first pivot poles30to the two second pivot poles50. Each of the two first pivot poles30is rotatable relative to each of the two second pivot poles50about the fixing pin40. A fastener200, such as screw, extends into the first through hole31of each of the two first pivot poles30and each of the two first pivot holes112, to secure the two first pivot poles30to the first mounting end11of the first blocking board10. Each of the two first pivot poles30is rotatable relative to the first blocking board10about the fastener200. Another fastener200extends into the second through hole51and each of the two second pivot holes211, to secure the two second pivot poles50to the first securing end21of the second blocking board20. Each of the two second pivot poles50is rotatable relative to the second blocking board20about the another fastener200. Two opposite ends of the first positioning shaft60are engaged with the two second mounting posts53of the two second pivot poles50. Two opposite ends of the second positioning shaft70are engaged with the two first mounting posts33of the two first pivot poles30. The first positioning shaft60is positioned in one of the plurality of locking slots16and abuts against the locking surface163. The second positioning shaft70is positioned in one of the plurality of latching slots26and abuts against the receiving surface263. The first blocking board10is supported above the second blocking board20by the two first pivot poles30, the two second pivot poles50, the first positioning shaft60, and the second positioning shaft70. A distance h1 between the first blocking board10and the second blocking board20can be adjusted to change a distance between the holding board103and the first blocking board10.

When the first distance h1 between the first blocking board10and the second blocking board20is adjusted, the first blocking board10is rotated up about the fastener200. The first positioning shaft60moves out of the locking slot16from the locking surface163to the guiding surface161, and the second positioning shaft70moves out of the latching slot26from the receiving surface263to the directing surface261. The two first pivot poles30and the two second pivot poles50are rotated relative to the first blocking board10and the second blocking board20, until the first positioning shaft60and the second positioning shaft70can be positioned on the directing surface261of another latching slot26and the guiding surface161of another locking slot16. The first blocking board10is rotated down. The first blocking board10is released, and the first positioning shaft60and the second positioning shaft70are moved from the directing surface261and the guiding surface161to the receiving surface263and the locking surface163respectively. The first positioning shaft60is engaged in another latching slot26, and the second positioning shaft70is engaged in another locking slot16. A second distance h2 between the first blocking board10and the second blocking board20is determined, and the distance between the first blocking board10and the holding board103is changed. In the illustrated embodiment ofFIG. 5, the second distance h2 is greater than the first distance h1. Therefore, the tested product can be tested in different distance between the holding board103and the first blocking board10.
