The technical scheme of the utility model as follows:

the triangular middle shaft comprises a lifting middle shaft body and is characterized in that three accommodating grooves are formed in the circumferential direction of the outer wall surface of the lifting middle shaft body and are respectively arranged in a penetrating mode along the axial direction of the lifting middle shaft body, and therefore the lifting middle shaft body is enabled to form a triangular middle shaft structure.

The triangular middle shaft is characterized in that the accommodating groove is of a concave arc groove structure.

The triangular middle shaft is characterized in that a threaded column for equipment installation is arranged at the top of the lifting middle shaft body.

The tripod with the triangular prism center shaft is characterized by comprising a base, three supporting foot frames and a triangular prism center shaft, wherein the three supporting foot frames are hinged to the base respectively, the triangular prism center shaft is arranged on the base in a penetrating mode, and three containing grooves of the triangular prism center shaft correspond to the three supporting foot frames in position one to one respectively.

The tripod with the triangular middle shaft is characterized in that a penetrating hole matched with the triangular middle shaft in shape is formed in the center of the base, a threaded hole communicated with the penetrating hole is formed in the side face of the base, and an adjusting and locking device is arranged in the threaded hole in a matched mode.

The tripod with the triangular prism center shaft is characterized in that the adjusting and locking device comprises a locking screw and a top block arranged at the tail end of the locking screw, the top block is of a convex arc structure and is tightly pressed at the position of a containing groove of the triangular prism center shaft through the convex arc structure.

The utility model has the advantages that:

1) the storage groove arranged in the triangular middle shaft can provide storage space for the supporting foot stand when the tripod contracts, so that the overall occupied space of the tripod is saved, and the portability of the tripod is improved.

2) The adjusting and locking device arranged on the base can adjust the position of the triangular middle shaft up and down, and the practicability of the tripod is improved.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example 1:

as shown in fig. 4, a triangular middle shaft comprises a lifting middle shaft body 3, wherein three receiving grooves 5 are formed in the outer wall surface of the lifting middle shaft body 3 along the circumferential direction, and the three receiving grooves 5 are respectively arranged along the lifting middle shaft body 3 in a penetrating manner in the axial direction, so that the lifting middle shaft body 3 forms a triangular middle shaft structure; in the embodiment, the accommodating groove 5 adopts a concave arc groove structure; and the lift 3 tops of axis body are equipped with the screw thread post 8 that are used for equipment fixing in this embodiment, can realize fixing and the location to equipment with camera equipment or check out test set's screw hole spiro union cooperation through screw thread post 8.

Example 2:

as shown in fig. 2-6, a tripod with a triangular middle shaft comprises a base 1, three supporting foot frames 2 and three triangular middle shafts, wherein the three supporting foot frames 2 are respectively hinged with the base 1 (the three supporting foot frames 2 are hinged by adopting a conventional hinged seat to be connected so as to be convenient for accommodating the supporting foot frames 2), the triangular middle shafts are arranged on the base 1 in a penetrating manner, and three accommodating grooves 5 of the triangular middle shafts are respectively in one-to-one correspondence with the positions of the three supporting foot frames 2.

In the embodiment, the center of the base 1 is provided with a through hole matched with the triangular middle shaft in shape, and the triangular middle shaft can move up and down in the through hole to adjust the height of the equipment so as to reach the optimal position.

In the embodiment, a threaded hole 4 communicated with the through hole is formed in the side surface of the base 1, and an adjusting and locking device is arranged in the threaded hole 4 in a matching manner; wherein adjust locking device and include locking screw 6 and set up at the terminal kicking block 7 of locking screw 6,

locking screw

6 and 4 spiro union cooperations of screw hole, kicking block 7 adopts convex arc structure to tightly in the centraxonial concave arc type groove 5 of triangular through convex arc structure top, wherein the convex arc structure and the concave arc type groove 5 of kicking block 7 laminate mutually, come to carry out the altitude mixture control to the triangular axis.
