Abstract

The utility model relates to a pipe joint for railing connection of guard rails, which is connected between a railing and a connected railing. The utility model comprises an integrally formed pipe joint body, wherein, the bottom of which is provided with a trepan boring matched with the end part of the railing, and the top surface of the body is provided with at least one elastic fastener which enters a jack of the connected railing after bearing pressure and is clamped after releasing the pressure. As long as the end part of the railing of the utility model is sheathed in the trepan boring on the bottom of the pipe joint body and the elastic fastener arranged on top of the pipe joint body is pushed into the jack of the connected railing to clamp the connected railing after releasing the pressure, in this way, the railing can be rapidly and firmly connected with the connected railing. The pipe joint of the utility model has the advantages of convenient installation and high installing work efficiency, and the utility model is suitable for the assembly and the connection of railings and connected railings in various shapes; moreover, products which are installed have the advantages of beautiful appearance, no defects and strong stereo perception.

Description

A kind of pipe joint that is used for the connection of guardrail railing

(1) technical field

The utility model relates to pipe joint, relates in particular to a kind of pipe joint that the guardrail railing connects that is used for.

(2) background technique

General plastic material assembly as the section bar assembly of door and window, sales counter, advertising lamp, is that angle connector by bidimensional or three-dimensional shape connects the section bar frame and forms.As the novel patent No. of practicality be 94221277.0, name is called " plastic material assembly " disclosed a kind of plastic material assembly, branch bar on its angle connector is hollow cavity, and being provided with opening slot along axial direction, is fixedlying connected of interference fit thereby form to divide between bar and the section bar inner chamber.The section bar assembly of this structure is promptly formed framework in the fixedly connected mode in angle with section bar, only is only applicable to the occasion that a small amount of section bar connects.And, have a large amount of railings need assemble connection in the present plastic guardrail, and obviously use said method, can cause the amount of finish of railing big, assembling process is loaded down with trivial details, and cost increases.Therefore,, simplify assembly process, usually the some montants of equidistant arrangement in two long parallel cross bars in order to reduce cost.But being connected between cross bar and montant, normally the cross bar of tubulose and montant are connected by welding, bonding or machanical fastener.This Placement still can't overcome the defective that loaded down with trivial details, on-the-spot amount of finish is big, packaging efficiency is low of assembling process, and outward appearance is produced adverse influence.

(3) the utility model content

The purpose of this utility model is to provide a kind of pipe joint that the guardrail railing connects that is used for, and by using this pipe joint, makes that the scene connection of guardrail railing is simple, quick, and packaging efficiency improves, and flat appearance is attractive in appearance.

A kind of pipe joint that the guardrail railing connects that is used for provided by the utility model, it is connected a railing and and is connected between the railing, it is characterized in that it comprises integrated pipe joint body, and: a trepanning that matches with the railing end had in the bottom of this body; This body end face is provided with at least one elasticity buckling member, and this elasticity buckling member enters the jack that is connected railing after being stressed, and engages after releasing power.

Above-mentioned be used for the pipe joint that the guardrail railing connects, wherein, the elasticity buckling member is formed two hemispheres by a neck and the hemisphere that is provided with in opposite directions that leaves the space with integrated two centres of neck on this neck.

The above-mentioned pipe joint that is used for the connection of guardrail railing, wherein, the shape of body end face is to be shaped face or the plane that negative and positive cooperate with the shape that is connected the railing interface.

The above-mentioned pipe joint that is used for the connection of guardrail railing, wherein, the two ends, the outside of body end face are extended one respectively and are coated the edge that is connected the railing outer rim.

Owing to adopted above-mentioned technical solution, as long as the railing end is linked in the trepanning of pipe joint body bottom, and the pushing of the elasticity buckling member that is provided with on the pipe joint bodies top entered the jack that is connected railing, release that engaging firmly is connected railing after the power, like this railing be connected railing with regard to quick, firm being connected of energy.The utility model is compared with existing Plastic Welding mode, and is simple, convenient, fast, and do not need to modify workpiece after having the top layer of not damaging assembly parts, solderless trace, assembling; Compare not water funk wet, good weatherability, firmly permanent with existing Placement; Compare with the existing machinery Placement, without metallic screw, can avoid getting rusty.Therefore, adopt that the utility model pipe joint is easy for installation, installation efficiency is high, is applicable to that the railing of different shape is connected with the assembling that is connected railing, and the product after assembling is specious, N/D, also have a stereoscopic impression.

(5) embodiment

As shown in Figure 7, the utility model pipe joint 10 uses in guardrail 20, is connected a railing 21 and and is connected between the railing 22, can select plastic material for use, opens injection mould, and is one-body molded.

Referring to Fig. 1-3, the first embodiment, this pipe joint 10 comprises the pipe joint body, has a square trepanning 2 that matches with square railing 21 ends in the bottom of this body; This body end face is provided with an elasticity buckling member, and this elasticity buckling member is made up of a neck 3 and two hemispheres 1 that are provided with in opposite directions on this neck 3, leaves the space in the middle of two hemispheres 1.

In conjunction with Fig. 7, after the elasticity buckling member is stressed, promptly two in opposite directions hemisphere 1 be tending towards closing up, open by the power of releasing after pushing the jack that is connected railing 22, and by neck 3 engagings.In addition, the shape of body end face 4 is the planes of matching with the square shape that is connected the railing interface, and two ends, the outside are extended one respectively and are coated the arc edge 5 that is connected railing 22 outer rims, make body end face 4 be coated on and are connected on the railing interface, reach the closed performance of jointing place.
