Embodiment
This disclosure content may be reused figure number and/or letter character in various examples.This reusable purpose is in order briefly to clearly demonstrate, itself do not specify the relation between the various embodiment that discussed and/or the configuration.
Please refer to the 1st figure, Figure 1 shows that decomposition chart according to a kind of height-adjustable drop test case of the utility model one embodiment.Outer container 100 places on the surface level, and interior case 102 is positioned at outer container 100, and can be in interior vertical movement, and each vertically is provided with a tooth bar 104 interior case 102 two opposite side walls.First rack 106 is horizontally placed on outer container 100 1 sidewalls, and it has a gear 108, can mesh with corresponding tooth bar 104.Second rack 114 is horizontally placed on outer container 100 sidewall relative with first rack 106, and it has a gear 108, gear 108 can with corresponding tooth bar 104 engagements.Self-locking block 112 is that gear 108 tops that are suspended from first rack, 106 1 ends are hung in rotating shaft with a side.When the outer container horizontal positioned, clamping mutually between self-locking block 112 and the gear 108, when outer container inclination certain angle, self-locking block 112 separates with gear 108.
Please refer to the 2nd figure, Figure 2 shows that schematic perspective view according to a kind of height-adjustable drop test case of the utility model one embodiment.Outer container 100 places on the surface level, and interior case 102 is positioned at outer container 100, and can move in vertical direction, and each vertically is provided with two tooth bars 104 interior case 102 two opposite side walls.Case one sidewall and outer container one sidewall in two rules 204 are vertically installed in.Outer container 100 has two half slots 202, is horizontally placed on outer container 100 two opposite side walls.First rack 106 is arranged in the half slot 202, and its two ends have two gears 108, can be respectively and corresponding tooth bar 104 engagements.Second rack 114 is horizontally placed in second half circular groove 202, and the one end has a gear 108, and the other end has a gear and a knob 206, and gear 108 can be respectively and corresponding tooth bar 104 engagements.Self-locking block 112 is that gear 108 tops that are suspended from first rack, 106 1 ends are hung in rotating shaft with a side.When outer container 100 horizontal positioned, clamping mutually between self-locking block 112 and the gear 108, when outer container 100 inclination certain angles, self-locking block 112 separates with gear 108.Knob 206 is rotated to outer container 100 outsides, and gear 108 drives tooth bar 104 rises interior case 102, with reference to rule 204 interior case 102 is adjusted to desired height.Knob 206 stops the rotation, because falling tendency appears in interior case 102 gravitates, self-locking block 112 will be because the self gravitation effect will continue contact on gear 108 this moment, and clamping mutually between the gear 108, stop gear 108 rotations, thereby case 102 glides in stoping, with these fixing interior case 102 height.
Please refer to the 3rd figure, Figure 3 shows that self-locking position partial side view according to a kind of height-adjustable drop test case of the utility model one embodiment.Tooth bar 104 and gear 108 engagements, falling tendency appears in interior case 102 gravitates, and this moment, self-locking block 112 was because the self gravitation effect continues contact on gear 108, and clamping mutually between the gear 108, stop gear 108 to rotate, thereby case 102 glide in stoping, with these fixing interior case 102 height.
Please refer to the 4th figure, Figure 4 shows that separation point position partial side view according to a kind of height-adjustable drop test case of the utility model one embodiment.With outer container 100 inclination certain angles, self-locking block 112 is because the self gravitation effect separates with gear 108, and case 102 can free movement in outer container 100 in this moment, and turning knob 206 with reference to rule 204, then can reduce interior case 102 to desired height.
By above-mentioned the utility model embodiment as can be known, application the utlity model has following advantage.Drop test case Height Adjustable promptly has versatility, makes it to adapt to the drop test of differing heights demand, saves the loaded down with trivial details and expense of making differing heights drop test case, and it can pass through gravity self-locking, and be easy and simple to handle.
Though the utility model discloses as above with embodiment; right its is not in order to limit the utility model; any those skilled in the art is not in breaking away from spirit and scope of the present utility model; when doing various changes and retouching, therefore protection domain of the present utility model is as the criterion when looking the accompanying Claim person of defining.
