Problems solved by technology

[0002] At present, tripods are basically composed of three telescopic tubes with locking structures. The structures of the telescopic tubes used on tripods on the market are basically the same, basically by adding some fixed locks between the tubes. It is completed with a tight structure, so it is difficult to control the cost, and the operation is relatively cumbersome, which brings great inconvenience to users.

Embodiment 1

[0021] see Figure 1-3 , a tripod telescopic rod, including a first tube 1, a second tube 2 and a triode 3, one end of the first tube 1 close to the diode 2 runs through the diode 2 and extends to the inside of the diode 2 and is movably connected to the inside of the diode 2, and the diode 2 One end close to the triode 3 runs through the triode 3 and extends to the inside of the triode 3 to be flexibly connected with the inner wall of the triode 3. The primary tube 1, the diode 2 and the triode 3 are all made of carbon fiber or glass fiber. The primary tube 1 and the diode 2 and the cross-sectional shape of the triode 3 can be designed in various ways. The cross-sectional shapes of the first-stage tube 1, diode 2 and triode 3 are designed to be ellipse, a circle with a plane, and a circle with anti-rotation grooves or convex lines to avoid the relative contact between the two tubes. Turn, the left and right sides of the primary tube 1, diode 2 and triode 3 are equally divided...

Embodiment 2

[0023] see Figure 4-5 , a tripod telescopic rod, including a first tube 1, a second tube 2 and a triode 3, one end of the first tube 1 close to the diode 2 runs through the diode 2 and extends to the inside of the diode 2 and is movably connected to the inside of the diode 2, and the diode 2 One end close to the triode 3 runs through the triode 3 and extends to the inside of the triode 3 to be flexibly connected with the inner wall of the triode 3. A gap 6 is provided on one side of the primary tube 1, the diode 2 and the triode 3. The primary tube 1 and the diode 2 Mounting holes 7 are provided on both sides of the notch 6 of the triode 3, an elastic member 8 is provided on the opposite side of the primary tube 1, diode 2 and triode 3, and a convex hull 9 is provided on the elastic member 8, and the convex hull 9 is connected to the triode 3. The assembly hole 7 is matched, and the elastic part 8 can be made of metal elastic material, rubber elastic material, or plastic elas...

Embodiment 3

[0025] see Figure 6-7 , a tripod telescopic rod, including a first tube 1, a second tube 2 and a triode 3, one end of the first tube 1 close to the diode 2 runs through the diode 2 and extends to the inside of the diode 2 and is movably connected to the inside of the diode 2, and the diode 2 One end close to the triode 3 runs through the triode 3 and extends to the inside of the triode 3 to be flexibly connected with the inner wall of the triode 3. A gap 6 is provided on one side of the primary tube 1, the diode 2 and the triode 3. The primary tube 1 and the diode 2 Mounting holes 7 are provided on both sides of the notch 6 of the triode 3, an elastic member 8 is provided on the opposite side of the primary tube 1, diode 2 and triode 3, and a convex hull 9 is provided on the elastic member 8, and the convex hull 9 is connected to the triode 3.

Abstract

The invention discloses a tripod telescopic rod. The tripod telescopic rod comprises a primary tube, a secondary tube and a tertiary tube, wherein the end, close to the secondary tube, of the primarytube penetrates through the secondary tube to extend to the inside of the secondary tube to be movably connected with the inside of the secondary tube, and the end, close to the tertiary tube, of thesecondary tube penetrates through the tertiary tube to extend to the inside of the tertiary tube to be movably connected with the inner wall of the tertiary tube; preferably, the left and right sidesof the primary tube, the secondary tube and the tertiary tube respectively are large heads and small heads, wherein the thicknesses of the large heads are larger than those of the small heads, each small head is provided with a taper, and each large head is not provided with a taper; and the primary tube, the secondary tube and the tertiary tube are made of carbon fiber or glass fiber. According to the tripod telescopic rod, through the mutual cooperation of the primary tube, the secondary tube, the tertiary tube, the large heads and the small heads, the locking requirement can be achieved bytwo sections directly without adding a connecting piece, the structure is simple, the operation is convenient, and great convenience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of photographic equipment, in particular to a telescopic rod for a tripod. Background technique [0002] At present, tripods are basically composed of three telescopic tubes with locking structures. The structures of the telescopic tubes used on tripods on the market are basically the same, basically by adding some fixed locks between the tubes. It is completed with a tight structure, so it is difficult to control the cost, and the operation is also relatively cumbersome, which brings great inconvenience to users. Contents of the invention [0003] The purpose of the present invention is to provide a tripod telescopic rod to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solution: a tripod telescopic rod, including a primary tube, a secondary tube and a triode, the end of the prim...
