Abstract

The utility model relates to an embedded inserting type PVC guard rail, which comprises a stand pole and a rail and a bar stripes connected with the stand pole as a whole. A rail inserting hole corresponding to the rail is positioned on one side of the rail or on the pole wall above one side. Two ends of the rail are respectively provided with the rail connecting piece corresponding to the rail inserting hole. A bar stripe inserting hole is positioned on the upper end face or the lower end face of the rail. Two ends of the bar stripe are respectively provided with the bar stripe connecting piece corresponding to the bar stripe inserting hole. The utility model adopts interpenetration type connecting, and the easy aged common plastic supporting jack and the easy rusted metal screw are not used between the bar stripe and the rail, between the rail and the stand pole, which completely solves the disadvantage that: the plastic supporting jack in the common PVC guard rail is easy to age and the metal screw is east to rust.

Description

A kind of insertion type PVC guardrail

One, technical field

The utility model relates to a kind of guardrail and railing, particularly a kind of insertion type PVC guardrail and railing.

Two, background technology

At present, the mode that the PVC guardrail of domestic production generally uses bearing socket and metal screw to connect, there is significant disadvantages in this connecting mode: 1) cross bar must be fixed by bearing socket and metal screw and column, grizzly bar also must connect with cross bar with the metal screw, because PP or PE plastics bearing socket are non-structural meterialss, and it is aging easily, can not bear the weight 2 of cross bar and grizzly bar for a long time) each metal screw all is a corrosion point and weak spot, can't realize that the zero dimension of PVC guardrail protects assurance, the screw of corrosion is the dangerous spot 3 of a destruction) because the screw connection, grizzly bar can only be fixed from the side, in addition in order to hide screw, need add block, thereby make the outward appearance of PVC guardrail two sides different, cause male and female face.

Three, summary of the invention

The purpose of this utility model is to provide a kind of and economizes except the metal screw in the member connection of PVC guardrail, has exempted corrosion, makes connection more reliable, and is more attractive in appearance, more convenient, the PVC guardrail that the life-span is longer.

For achieving the above object, the technical solution adopted in the utility model is: comprise column and the cross bar and the grizzly bar that are connected as a single entity with column, its characteristics are to offer and the corresponding cross bar jack of cross bar on the one side of column or the post jamb more than the one side, be respectively arranged with and the corresponding cross rod connector of cross bar jack at the two ends of cross bar, and on the upper surface of cross bar or lower surface, offer the grizzly bar jack respectively, be respectively arranged with at the two ends of grizzly bar and the corresponding grizzly bar connector of grizzly bar jack.

Another characteristics of the present utility model are: cross rod connector and grizzly bar connector are the anti-avulsion inclined-plane of a projection; Also can one self-locking inserts be set in cross bar one side by fixture, two foots of self-locking inserts respectively are provided with an inwardly protruded buckle, self-locking inserts and cross bar interference are installed, the upper/lower terminal of the same side of grizzly bar respectively offer the jack identical with self-locking inserts shape and with the buckle corresponding positioning hole.

Because the utility model adopts cross-linking to connect; do not re-use easily aging common plastics bearing socket between grizzly bar and cross bar, cross bar and the column and the metal screw of easy-to-rust connects; thoroughly solved the shortcoming of the easily aging and metal screw easy-to-rust of plastics bearing socket in the common PVC guardrail; and cross bar or column inside needn't serve as a contrast the steel pipe of relying and connecting with screw as the common PVC guardrail; realized the lightweight and the environmental protectionization of PVC guardrail, provided cost savings greatly.

Five, the specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operating principle are described in further detail.

Embodiment 1, referring to Fig. 1,2, present embodiment comprises column 1 and the cross bar 2 and the grizzly bar 3 that are connected as a single entity with column 1, offer and cross bar 2 corresponding cross bar jacks 4 in the one side of column 1 or on the post jamb simultaneously, be respectively arranged with and the cross bar jack 4 corresponding cross rod connectors 5 that bossed anti-avulsion inclined-plane is set at the two ends of cross bar 2, and on the upper surface of cross bar 2 or lower surface, offer grizzly bar jack 6 respectively, be respectively arranged with at the two ends of grizzly bar 3 and the grizzly bar jack 6 corresponding grizzly bar connectors 7 that bossed anti-avulsion inclined-plane is set.During assembling, cross rod connector on the cross bar 25 is inserted in the cross bar jack of offering on the column 14, because cross rod connector 5 is the anti-avulsion inclined-plane of a projection, elastic deformation can take place when inserting cross bar jack 4, the purpose of upspringing and reach fixing and prevent deviating from the projection anti-avulsion inclined-plane of insertion rear transverse rod connector 5, grizzly bar 3 is connected with cross bar 2 and column 1 with cross bar 2, because projection anti-avulsion inclined-plane plays a part check (non-return) valve, makes cross bar 2 and column 1, cross bar 2 and grizzly bar 3 insert the back and just can not reversely extract.

Embodiment 2, referring to Fig. 3,4,5,6, present embodiment cross bar 2 one sides are provided with a self-locking inserts 9 by fixture 8, and two foots of self-locking inserts 9 respectively are provided with an inwardly protruded buckle 10, self-locking inserts 9 is installed with cross bar 2 interference, the upper/lower terminal of the same side of grizzly bar 3 respectively offer the jack 11 identical with self-locking inserts 9 shapes and with buckle 10 corresponding positioning hole 12.During assembling, the jack 11 of grizzly bar 3 upper/lower terminals is set on the cross bar 2 self-locking inserts 9, because self-locking inserts 9 adopts interference to install with cross bar 2, self-locking inserts 9 can snap in the jack 11 of grizzly bar 3 when firmly moving down grizzly bar 3, the inwardly protruded buckle 10 of self-locking inserts 9 can enter in two locating holes 12 of jack 11 in folding process, reach the self-locking purpose, other annexation together

Embodiment 1.
