Description

The sealing structure of pipe fitting tighting device for support

Technical field

This utility model relates to the technical field in terms of a kind of pipe fitting tighting device for support, particularly relate to one can prevent rainwater and Dust enters between the pipe fitting of mutually socket, to provide the sealing knot of the pipe fitting tighting device for support of good waterproof and dust-proof effect Structure.

Background technology

The pipe fitting of general mutually socket is the effect making it have flexible adjustment, it will usually arrange a ditch in the upper end of outer tube Groove, then a sheathed tighting device for support then at the upper end of this outer tube, tightening with the caliber forcing this outer tube by this tighting device for support Reduce the purpose reaching to tighten inner tube.Such as: after the vertical tube of bicycle saddle cushion is in the seat pipe be inserted in vehicle frame, can be with a branch of Tight device tightens the upper end of seat pipe, fixes in order to reach to install saddle-tube and adjusts effect highly.Known to tighten Device is merely the upper end utilizing the most C-shaped a branch of ring set to be located at this outer tube, is screw-locked at this bundle with a packing bolt the most again Two openings of ring.Therefore, though its can reach adjust inner and outer pipe stretch location effect, but the socket place meeting of this inner and outer pipe It is revealed in outer completely and is easily invaded between this inner and outer pipe by the foreign body such as rainwater and dust, thus be easily caused socket place and give birth to Rust corrosion or block card and wait indefinitely problem.

At present, though having dealer to be used in the sheathed sealing member of this beam ring upper side, in order to prevent rainwater and dust outer by this Pipe upper end invades, as Taiwan is announced shown in M369893 patent with the socket place of inner tube.But, as shown in Figure 1, 2, due to In the sealing structure of this known pipe fitting tighting device for support, its sealing member 10 only covers the upper side of this beam ring 11 and the set of this inner tube 12 Meeting place, therefore it can only prevent rainwater and dust from being invaded by the upper side of this beam ring 11, and rainwater but cannot be prevented by this beam ring 11 Breach 13 and the groove 15 of this outer tube 14 invade the socket place to this inner and outer pipe 12,14, therefore it is waterproof and dust-proof effect is non- Constant, and the corrosion or block card and wait indefinitely problem of still suffering from getting rusty easily.

Utility model content

The sealing structure of known pipe fitting tighting device for support also exists waterproof and dust-proof effect is poor, and easily makes socket place get rusty Corrosion or block card and wait indefinitely problems.

This utility model provides the sealing structure of a kind of pipe fitting tighting device for support, including a beam ring, a forcing piece and a sealing Part.Wherein, what this beam ring had that a branch of groove is available for being sheathed on an outer tube tightens on end, and the side of this beam ring has and is communicated to this bundle One breach of groove, on the both ends forming this breach, convex is provided with two corresponding projections.It is two convex that this forcing piece links this Block, be available for forcing this two projection close to each other so that this beam ring order about this outer tube tighten in end tightens and be inserted in therein one Pipe.This sealing member is made up of flexual material, and it includes a ring and an Extendible flake, and this ring is covered on the upper of this beam ring Side, this ring has the endoporus run through, and makes the internal face of this endoporus be posted by the outer peripheral face of this inner tube, this Extendible flake Extended to can cover on this two projection the breach between this two projection by the side of this ring.

Compared with prior art, the beneficial effects of the utility model are: dress tightened by pipe fitting provided by the utility model The sealing structure put, can cover the upper side of this beam ring and the socket place of this inner tube, to prevent by the ring of this sealing member Rainwater and dust are invaded by the upper side of this beam ring, it is possible to utilize the Extendible flake of this sealing member to cover lacking between this two projection Mouthful, to prevent rainwater and dust from being invaded by the breach of this beam ring, and then its waterproof and dust-proof effect can be effectively increased.

Particularly, the Extendible flake of this sealing member may extend into the lower section of this two projection to cover all this breach, and makes Rainwater and dust cannot be invaded by the breach of this beam ring completely, and can extend side especially below this Extendible flake still further below Cover plate, makes this side cover sheet cover all the groove of this outer tube, to prevent rainwater and dust from being invaded by the groove of this outer tube, so Just can the most effectively prevent rainwater and dust from entering between this outer tube and this inner tube of mutually socket, to make it have more Good waterproof and dust-proof effect.
