Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Defer to technique scheme, as shown in Figures 1 to 5, a kind of shatter-resistant is measured tripod, comprises tripod, and tripod is by triangle base 1, and three supporting legs 4 that are hinged on three limits of base 1 lower surface form, and the length of supporting leg 4 is adjustable.Identical with existing tripod structure, in the utility model, the agent structure of tripod is three supporting legs 4 that are hinged on base 1 bottom margin, in the time that tripod uses, article three, supporting leg 4 pulls open to tripod outside, makes to form three-legged structure between three supporting legs 4, keeps the stability of instrument on base 1.The length of supporting leg 4 can be adjusted by the adjusting knob 5 on supporting leg 4, so that the height of tripod meets usage requirement.
On base 1 lower surface, fixed plate 10 is installed, fixed plate 10 is a plate body, be close to setting with base 1 lower surface, angle limits frame is installed on fixed plate 10, angle limits frame comprises the first support plate 8 and the second support plate 2 that end is consolidated, the first support plate 8 is vertically cemented on fixed plate 10, and the angle between the second support plate 2 and fixed plate 10 is 5 °～10 °; Both sides at two support plates are all consolidated with fan shape baffle 7.The joint of the first support plate 8 and the second support plate 2 is provided with flexural pivot 9, and elastic fulcrum bar 3 is arranged on flexural pivot 9, and elastic fulcrum bar 3 can be stretched out tripod in the space between two supporting legs 4.
The first support plate 8, the second support plate 2 and fan shape baffle 7 provide a space for elastic fulcrum bar 3: in the time that elastic fulcrum bar 3 moves, its moving direction is subject to the restriction of two support plates and fan shape baffle 7, it can not be moved towards fan shape baffle 7 directions, and can only between the first support plate 8 and the second support plate 2, move, and, elastic fulcrum bar 3, towards the moving direction of the second support plate 2, is towards the direction between two supporting legs 4 of tripod.
In the time that tripod uses, first need the bearing of tripod to be adjusted to level, now fixed plate 10 is also in level, and the first support plate 8 is perpendicular to horizontal plane, and between the second support plate 2 and horizontal plane, angle is 5 °～10 °.Set after tripod, it remains static, and elastic fulcrum bar 3, in vertical state, contacts with the first support plate 8.When elastic fulcrum bar 3 moves in angle limits frame, multipotency reaches the position contacting with the second support plate 2, and the state that can not be up to the standard, simultaneously can not be to the direction motion towards fan shape baffle 7.
The structures shape of tripod tripod while in use toppling over, fall down towards the direction between two supporting legs 4 in most cases.In the time that tripod is lied down, due to effect of inertia, stretch out from the space between two supporting legs 4 of tripod the lower end of elastic fulcrum bar 3, due to the angle effect between the second support plate 2 and fixed plate 10, make the lower end of elastic fulcrum bar 3 in the time of vertical kiss the earth, base 1 can be higher apart from the distance on ground, if and angle is 0 ° between the second support plate 2 and horizontal plane, base 1 can be smaller with the distance on ground so, open at supporting leg 4 angle too small time, this situation likely makes the instrument on tripod touch ground, as shown in Figures 2 and 3.Show through a large amount of practical applications, when the angle between the second support plate 2 and fixed plate 10 is 5 °～10 °, when tripod is toppled over, elastic fulcrum bar 3 can contact with ground is desirable, normally works.
Preferably, elastic fulcrum bar 3 adopts rubber rod, has certain elastic reaction, and its lower end is arranged to horn-like, the area of contact of increase and bottom surface, and its length is preferably set to 15cm～20cm.
Angle limits frame and fixed plate 10 are integral type structure, on the base 1 of tripod and fixed plate 10, all offer bolt hole, fixed plate 10 is arranged on the lower surface of base 1 by bolt 6, is convenient to install and change, and also can reequip existing tripod easily simultaneously.
As shown in Figure 5; in the time that tripod is toppled over; elastic fulcrum bar 3 throws away between two supporting legs 4 by inertia; before contacting with ground, tripod superstructure and instrument contact with ground; increase dumping time by its flexible characteristic, rely on the rigidity characteristics of rubber rod, support tripod superstructure simultaneously; it is not contacted with ground, thus the instrument on protection top.Angle limits frame can limit the angle that throws away of rubber rod, make it can only be towards the direction between two supporting legs 4, be that the direction that tripod is toppled over throws away, and when tripod is toppled over and ground is angled, distance between elevating base 1 and bottom surface, the horn-like lower end that simultaneously ensures rubber rod contacts with ground, prevents because throwing away angle excessive and ineffective.
