Background

Tripods are common equipment in the fields of photography, surveying and mapping, industrial measurement and the like, and are mainly used for supporting and stabilizing cameras, theodolites, total stations and other instrument equipment. Tripods need to be first leveled in use to ensure that the instrumentation mounted on the tripod is level.

In the leveling process of tripod, need refer to the spirit level, often need relapse the length of adjusting the tripod support many times in order to ensure that the bubble in the spirit level is placed in the middle, and in the adjustment process, because the structural problem of tripod, often to the trend that one side was emptyd in the adjustment process, influence the efficiency and the precision of adjustment, simultaneously because tripod self weight is heavier, also comparatively labouring when the adjustment. It follows that this is time and effort intensive to achieve tripod levelling work to ensure that the measurement or photographic equipment thereon is at absolute level.

In view of this, the present application is specifically made.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the utility model provides a tripod, can be comparatively accurate and laborsaving carry out the leveling operation. The utility model provides a solve the above-mentioned problem a tripod convenient to leveling.

The utility model discloses a following technical scheme realizes:

a tripod convenient for leveling comprises a base, three bases and three brackets surrounding the base;

the base is provided with a universal level meter used for indicating the level degree of the mounting surface of the base equipment;

the bracket comprises a first adjusting part for roughly adjusting the length of the bracket and a second adjusting part for finely adjusting the length of the bracket, wherein the first adjusting part comprises an upper supporting part hinged with the base and a middle supporting part which can stretch out and draw back at one end of the upper supporting part, and a stabilizing part for fixing the middle supporting part is arranged on the upper supporting part;

the second adjusting part comprises a lower supporting part and a joint part arranged at one end of the middle supporting part far away from the upper supporting part, the lower supporting part is provided with an adjusting chamber capable of being sleeved on the joint part, one end of the lower supporting part provided with the adjusting chamber is rotatably connected with a threaded adjusting part, the threaded adjusting part is sleeved on the joint part and is in threaded connection with the joint part, and an elastic element which is extruded is arranged between the end part of the joint part and the adjusting chamber; the other end of the lower supporting piece is hinged with the base in a universal mode.

According to the scheme, after the tripod is placed, if the tripod is required to be leveled, first adjusting parts of three supports are roughly adjusted according to the sight line, so that the middle support piece stretches out and draws back in the upper support piece to be roughly leveled, then the corresponding support is finely adjusted according to the deflection position of air bubbles in the universal level, the position of the joint part in the adjusting chamber is adjusted by rotating a thread adjusting piece of the corresponding support while observing the universal level, and the middle support piece is driven to slightly stretch out and draw back in the lower support piece, so that the overall length of the support is proper, the adjusting speed is slow and uniform, the operation is convenient, the adjusting precision is high, and the equipment mounting surface of the base can be accurately horizontally arranged; in addition, be equipped with between the coupling portion tip and the regulation cavity and receive extruded elastic element, through elastic element can alleviate the tripod to the extrusion of coupling portion, and then reduce the screw thread regulating part with the frictional force of coupling portion connecting thread for the regulation of screw thread regulating part is more laborsaving, reduces the injury of friction to the screw thread simultaneously, improves the life of device.
