Description

Telescopic rod

Technical Field

The utility model relates to a telescopic link field especially relates to a telescopic link.

Background

At present, the existing carbon fiber selfie stick/telescopic rod in the market is generally connected and fixed through a taper pipe with one large end and one small end, one selfie stick/telescopic rod consisting of a plurality of sections of taper pipes can only realize two lengths of longest stretching or shortest shrinking, the structure can not meet the use requirements of various lengths, and in addition, each section of the selfie stick/telescopic rod is used for adjusting various lengths, so that the selfie stick/telescopic rod can be locked together with two adjacent sections of the selfie stick/telescopic rod, the limitation of different lengths is realized, but the existing fixing mode in the market has the problems of large and redundant structure after storage, length waste and the like, the threaded connecting rings or the buckles used for adjusting the lengths can occupy large storage space, and the storage space is long and the appearance is bloated.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides a telescopic rod which has simple appearance and does not occupy the redundant space.

The utility model provides a telescopic link, including a plurality of taper pipes that cup joint in proper order, a plurality of taper pipes include that the free end outside is equipped with a plurality of first taper pipes of flexible ring and locates every adjacent two a plurality of second taper pipe between the first taper pipe works as when a plurality of taper pipes are in the shrink state, it flexible ring is adjacent rather than the periphery be interference fit between the inner wall of first taper pipe free end.

As a further improvement of the utility model, the first tapering pipe free end outside with still be equipped with the go-between the flexible ring, the go-between with be fixed connection between the first tapering pipe, the go-between is equipped with the annular mounting groove, the flexible ring is installed in the annular mounting groove.

As a further improvement of the utility model, the flexible ring is a rubber flexible ring.

As a further improvement of the utility model, a plurality of taper pipes are carbon fiber taper pipes.

As a further improvement of the utility model, still include the connecting seat that is used for being connected with other accessories, the connecting seat with be located the center first taper pipe free end fixed connection.

As a further improvement of the utility model, the connecting seat is a threaded connection rod.

The utility model has the advantages that: the utility model discloses the go-between that is used for adjusting length after the telescopic link is accomodate can be hidden in the expansion pipe, does not influence and accomodates length and outward appearance, and easy operation is swift moreover, need not just can stretch or fixed telescopic link through complicated operation.

Detailed Description

As shown in fig. 1 and 2, the present invention discloses a telescopic rod, which comprises a plurality of taper pipes 1 sleeved in sequence, wherein the taper pipes 1 comprise a plurality of first taper pipes 11 provided with flexible rings at the outer sides of the free ends thereof and a plurality of second taper pipes 12 arranged between every two adjacent first taper pipes, when the taper pipes of the taper pipes are in a contracted state, the flexible rings 13 are in interference fit with the inner walls of the free ends of the first taper pipes 11 adjacent to the outer peripheries thereof, so that when the taper pipes 1 are retracted, the flexible rings 13 form interference fit with the inner walls of the thicker first taper pipes 11, so that the two first taper pipes 11 can be fixed, thereby adjusting various lengths of the telescopic rod, and each flexible ring 13 is inserted into the thicker first taper pipe 11, so that only the outermost first taper pipe 11 can be seen outside, how the inner part is limited cannot be seen, so that the telescopic rod of the telescopic rod is simpler, the limiting mechanism cannot occupy more accommodating space, and the flexible ring 13 of the outermost first taper pipe 11 can be arranged according to requirements without installation if not required.

In the technical scheme, a connecting ring 14 is further arranged between the outer side of the free end of the first taper pipe 11 and the flexible ring 13, the connecting ring 14 is fixedly connected with the first taper pipe 11, the connecting ring 14 is provided with an annular mounting groove, and the flexible ring 13 is mounted in the annular mounting groove, so that the flexible ring 13 can be better fixed, and the limiting is more reliable.

In the technical scheme, the flexible ring 13 is a rubber flexible ring or a silica gel flexible ring and the like, so that the cost is low and the flexibility is good.

In this technical scheme, a plurality of taper pipes 1 are carbon fiber taper pipes, and carbon fiber pipe is more durable.

In this technical scheme, still include the connecting seat that is used for being connected with other accessories, the connecting seat with be located the center first taper pipe 11 free end fixed connection, its connecting seat can be connected with external accessories such as motion camera, cell-phone frame to realize different functions.

In some embodiments, the connecting seat is a threaded connecting rod, and the threaded connecting rod can be a standard connecting screw rod, so that other accessories can be conveniently matched, the universality is better, and the connection is more convenient.

The utility model discloses the go-between 14 that is used for adjusting length after the telescopic link is accomodate can hide in the telescopic tube, does not influence and accomodate length and outward appearance, and easy operation is swift moreover, need not just can stretch or fixed telescopic link through complicated operation.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
