A telescopic floating rectangular tube sleeve

Abstract

The invention discloses a telescopic floating type rectangular pipe sleeve. The telescopic floating type rectangular pipe sleeve comprises a pipe body, a fine adjustment mechanism and telescopic mechanisms, wherein the pipe body comprises a left half pipe and a right half pipe; the telescopic mechanism is arranged on each of the exteriors of two sides of the left half pipe and the right half pipe;the left half pipe and the right half pipe comprise lower half parts with guide pillars and upper half parts with guide grooves; the guide pillars and the guide grooves are in abutting joint; each telescopic mechanism comprises a telescopic thread pillar, a telescopic thread sleeve and a telescopic lantern ring; the telescopic lantern rings are arranged at the outer sides of the upper half partsof the left half pipe and the right half pipe; the telescopic thread pillars are arranged at the outer sides of the lower half parts of the left half pipe and the right half pipe; the upper ends of the telescopic thread pillars are connected to the telescopic lantern rings in a penetration manner; the telescopic thread sleeves are arranged on the telescopic thread pillars by threads and are located below the telescopic lantern rings; and the telescopic thread pillars, the telescopic lantern rings and the upper parts of the left half pipe and the right half pipe are fixed by threaded rods in apenetration connecting manner. The telescopic floating type rectangular pipe sleeve realizes the expansion of insertion space.

Description

technical field [0001] The invention relates to a telescopic floating rectangular pipe sleeve. Background technique [0002] At present, in order to protect the pipe body made of metal, a matching rectangular pipe sleeve has been produced, and the pipe body made of metal can be inserted into the rectangular pipe sleeve. The existing rectangular pipe sleeve is generally made of polypropylene material. For injection molding, the current rectangular pipe sleeve has a long strip structure with a rectangular cross section, and then the metal pipe body can be directly inserted into the rectangular pipe sleeve, but sometimes the friction between the metal pipe body and the rectangular pipe sleeve is relatively large. It is difficult to insert; in addition, if the contact surface between the rectangular tube sleeve and the metal tube body is not large, the metal tube will slip in the rectangular tube sleeve, resulting in the instability of the rectangular tube sleeve and the metal t...

It is difficult to insert; in addition, if the contact surface between the rectangular tube sleeve and the metal tube body is not large, the metal tube will slip in the rectangular tube sleeve, resulting in the instability of the rectangular tube sleeve and the metal tube socket; in addition, the rectangular tube The up and down distance of the sleeve cannot be adjusted, so that the use range of the rectangular sleeve is limited and the use is inflexible
