Description

Stable guiding tripod

Technical Field

The utility model relates to the technical field of tripods, in particular to a stable guide tripod.

Background

The tripod is made of aluminum profiles and comprises a fixed rod, wherein two sides of the fixed rod are provided with symmetrically arranged telescopic rods.

In order to realize telescopic guiding of the telescopic rod, guide blocks are generally arranged at the upper end and the lower end of the fixed rod. When the telescopic link stretches out and draws back, the guide block that is located the dead lever top plays the guide effect all the time, but when the telescopic link stretches out, can break away from with the guide block of lower extreme, only flexible direction through the guide block at top, the guide effect is relatively poor. Therefore, the guide block at the lower end is fixed on the inner side of the telescopic rod through the bolt. So the guide block of lower extreme not only installs the difficulty, and aluminium alloy cavity produces deformation easily moreover to lead to the guide block position deviation ratio of lower extreme great, lead to the expansion stability of telescopic link relatively poor.

Therefore, how to overcome the above-mentioned drawbacks is a problem to be solved by the person skilled in the art.

Disclosure of Invention

In order to solve the technical problems in the background technology, the utility model discloses a stable guiding tripod.

The utility model provides a stable guide tripod, which comprises a fixed rod, wherein symmetrical telescopic rods are arranged on two sides of the fixed rod, the telescopic rods are guided in a telescopic way through a first guide block and a second guide block which are sequentially arranged up and down, and plugs are clamped at the lower ends of the telescopic rods; the second guide block is arranged on the plugging head.

The structural strength of the plug is stable, and the second guide block is arranged on the plug, so that the position of the second guide block is stable, and the telescopic stability of the telescopic rod is improved.

The second guide block is fixed on the plug through welding or bolt locking, the operation is complex, and the position accuracy is lower, so that the problem is further improved and solved, and the second guide block and the plug are integrally cast and formed.

The specific structure of the plug is as follows: the plug comprises a limiting plate, a clamping pipe and a second guide block, wherein the clamping pipe and the second guide block are arranged at the upper end of the limiting plate; the telescopic rod is sleeved with the clamping pipe and abuts against the limiting plate; the inner side of the telescopic rod is clamped between the second guide block and the clamping pipe.

The plug is connected with the telescopic rod in a clamping way, and is easy to fall off, so that the problem is further improved and solved, and in particular, the inner side of the telescopic rod is fixed with the clamping pipe through a fastener.

When the inner side of the telescopic rod is fixed with the clamping pipe, the operation space is small, so that the disassembly and assembly are difficult, the problem is further improved and solved, and particularly, the bayonet is arranged on the outer side of the clamping pipe and is clamped with the clamping plate. And (5) when the clamping plate is disassembled and assembled, the clamping plate is taken out.

Because two telescopic links need synchronous flexible, based on this, further design is: the telescopic rod is fixedly connected with the telescopic rod.

The conventional fixed sleeve is fixed with the telescopic rods through screws, the telescopic rods are far away from the fixed rods during locking, and the position is deviated, so that the problem is further improved and solved, specifically, one side of the fixed sleeve is fixedly connected with one telescopic rod through a plurality of self-tapping screws, the other side of the fixed sleeve is provided with a threaded connection jacking bolt, and the threaded end of the threaded connection jacking bolt jacks the other telescopic rod. And the jack bolt is screwed to form pressure on the telescopic rod, so that the position of the telescopic rod is kept stable.

Because the transition rotation of the jacking bolt can fall off from the fixed sleeve to cause loss, the problem is further improved and solved, and specifically, the end part of the threaded end of the jacking bolt is also clamped with a clamp spring, and the clamp spring is positioned in the fixed sleeve.

Detailed Description

The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

Embodiment one:

as shown in fig. 1 and 2, the utility model is a stable guiding tripod, which comprises a fixed rod 1, and two sides of the fixed rod are clamped with symmetrically arranged telescopic rods 2. The upper ends of the two telescopic rods 2 are fixedly connected through a sleeve, and the lower ends of the two telescopic rods are fixedly connected through a fixing sleeve 6, so that synchronous telescoping is realized. The upper end of the fixed rod 1 is provided with a first guide block 3, two sides of which are propped against the telescopic rod 2 for lifting and guiding the telescopic rod 2.

The lower extreme joint of telescopic link 2 has end cap 5, specifically does: the plug 5 comprises a limiting plate 51 and a clamping tube 52 arranged at the upper end of the limiting plate 51. The clamping pipe 52 is a rectangular block, the telescopic rod 2 is also a rectangular pipe, and is clamped with the clamping pipe 52 in a sleeved mode and abuts against the limiting plate 51, so that the installation limiting is realized. As shown in fig. 4 and 7, the second guide block 4 mounted on the limiting plate 51 is provided on the inner side of the clamping tube 52, and the second guide block 4 abuts against the fixing rod 1 for lifting and guiding the telescopic rod 2.
