Abstract

The utility model relates to a clamping structure of a cross bar and a vertical bar of a fence, solving the problems of complicated assembly, long assembly consumed time, high cost and easiness of being stolen of the vertical bars of the traditional assembled fence cross bar and vertical bar. The clamping structure comprises a hollow cross bar and a vertical bar, wherein a plug hole running through the upper surface and the lower surface of the cross bar is formed in the cross bar, and the vertical bar is plugged in the plug hole of the cross bar. The clamping structure is characterized in that the vertical bar and the cross bar are clamped and fixed through a clamping sleeve; at least one side of the body of the vertical bar plugged in the cross bar is provided with a mounting hole; one end of the clamping sleeve is bonded to the body of the vertical bar and clamped at the mounting hole, while the other end of the clamping sleeve is provided with a concave U-shaped trough which is clamped on the hole wall of the plug hole of the cross bar; and both ends of the clamping sleeve extend along the direction of the body of the vertical bar and are connected with an outwards tilted elastic piece. According to the clamping structure, because the cross bar and the vertical bar of the fence are fixed by adopting the clamping sleeve, the structure is simple, and extra tools are not needed during mounting, so that the clamping structure is convenient for mounting; and because the clamping sleeve is positioned in the cross bar, the anti-theft performance is good.

Description

A kind of fence cross bar and montant interface arrangment

Technical field

The utility model relates to the fence production technical field, the interface arrangment that particularly a kind of fence cross bar is connected with montant employing cutting ferrule.

Background technology

Existing steel pipe fence adopts assembly type usually, and with convenient transportation, cross bar and montant adopt connected structure usually, use plain bolt fixed transverse rod and montant then.Employing is bolted to the montant on the cross bar, uses general instrument just can bolt be unclamped, and extracts montant out, and montant is easy to stolen, and fixing so consuming time long, need to use more bolt, nut, cost is higher; Also there is the part fence to adopt certain anti-theft measure; Announced a kind of fence like the utility model of notification number CN201162378Y, this fence is established locating hole on montant, and locating hole is positioned at cross bar; Backstay is axially disposed within the cross bar along cross bar; And be arranged in the locating hole of montant, though this mode can be guarded against theft, the assembling process of fence is complicated.

Summary of the invention

The purpose of the utility model be to solve between existing assembling fence cross bar and the montant assembling complicated, assemble that length consuming time, cost are high, montant is easy to stolen problem; Provide a kind of simple in structure, assembling easily, cost is low, is difficult for the structure that links of stolen fence cross bar and montant.

The utility model solves the technical scheme that its technical problem adopted: a kind of fence cross bar and montant interface arrangment; Comprise hollow cross bar, montant, cross bar is provided with the spliced eye that connects upper and lower surfaces, and montant is plugged in the cross bar spliced eye; Cross bar and montant connect and fix through cutting ferrule; Be plugged on the inner at least one side mounting holes of montant shaft of cross bar, an end applying montant shaft of cutting ferrule also is connected to the installing hole place, and the other end of cutting ferrule is provided with the U-shaped draw-in groove of indent; The U-shaped draw-in groove is connected on the cross bar spliced eye hole wall, and the shell fragment of perk links to each other through outwards extend also along montant shaft direction between the cutting ferrule two ends.During assembling, only need cutting ferrule one end is snapped fit onto on the montant, then with cross bar socket montant; Cross bar spliced eye hole wall compressing shell fragment makes the shell fragment distortion; When cross bar spliced eye hole wall moves to U-shaped draw-in groove position, the shell fragment resilience, the U-shaped draw-in groove is connected on the cross bar spliced eye hole wall.The assembling of this device is simple, need not extra accessory assemblings such as screw, and is positioned at the inside of cross bar after the cutting ferrule installation, is difficult for being disassembled good anti-theft effect.

As preferably, the block tongue that interruption-forming inwardly launches is broken through in said cutting ferrule and installing hole access section, and the end of cutting ferrule also is provided with inside bending, rubber-like V-arrangement dop, and block tongue and V-arrangement dop match with the hole wall up and down of montant installing hole respectively.During assembling, be located in the downside hole wall of installing hole earlier with block tongue, then the V-arrangement dop is pressed in the installing hole, make the V-arrangement dop be connected to installing hole upside hole wall and fix, assembling process need not by instrument, simple and fast.

As preferably, the spliced eye hole wall clamping of the U-shaped draw-in groove of said cutting ferrule and cross bar soffit is provided with waterproof washer between the spliced eye hole wall of said cross bar upper surface and the montant.Fence generally uses out of doors, therefore must consider the problem of water proof and dust proof, therefore with the snap fit structure design at the cross bar soffit, and the cross bar upper surface adopts waterproof washer to do protection, avoids causing corrosion in rainwater and the dust entering cross bar.

As preferably, two opposite flanks of said montant shaft are equipped with the cutting ferrule with the cross bar clamping.

As preferred other preferred version, said montant shaft is square, and four sides of montant shaft are equipped with the cutting ferrule with the cross bar clamping.

The cross bar of fence and montant adopt cutting ferrule to fix in the utility model, and be simple in structure, need not extra instrument during installation, easy for installation; Cutting ferrule is positioned at the inside of cross bar, and theftproof performance is good.

Among the figure: 1, cross bar, 2, montant, 3, spliced eye, 4, cutting ferrule, 5, installing hole, 6, the V-arrangement dop, 7, block tongue, 8, shell fragment, 9, the U-shaped draw-in groove, 10, waterproof washer.

The specific embodiment

Below through specific embodiment, and combine accompanying drawing, the technical scheme of the utility model is further specified.

Embodiment: like Fig. 1 to a kind of fence cross bar shown in Figure 3 and the cutting ferrule syndeton of montant; Comprise cross bar 1 and montant 2; Offer the spliced eye 3 that runs through upper and lower surfaces on the cross bar 1; Montant 2 is plugged in the spliced eye 3 of cross bar 1, is provided with waterproof apron 10 between the spliced eye 3 of cross bar 1 upper surface and the montant 2 bar walls, and the spliced eye of cross bar 1 soffit and montant 2 adopt cutting ferrule 4 to connect and fix.

Cutting ferrule 4 structures such as Fig. 2, shown in Figure 3, cutting ferrule 4 adopts stainless steel material to process, and cutting ferrule 4 tops are the plane of being close to montant 2 bar walls; To lean on montant one side is the inboard; Cutting ferrule is close to dash on the plane of montant 2 bar walls and is established the block tongue 7 that cut forms inside expansion, and cutting ferrule upper end side is provided with inside bending, rubber-like V-arrangement dop 6, offers installing hole 5 on the montant bar wall; Block tongue 7 is buckled in the downside hole wall of installing hole 5, and V-arrangement dop 6 is pushed the upside hole wall that snaps in installing hole 5.Cutting ferrule 4 middle parts perks laterally forms shell fragment 8, is the U-shaped draw-in groove 9 that the lower end of shell fragment 8 is provided with indent in the bottom of cutting ferrule, and U-shaped draw-in groove 9 is connected on spliced eye 3 hole walls of cross bar soffit.

As shown in Figure 3; During installation, cutting ferrule 4 is fixed on montant 2 sidewalls that are positioned at cross bar 1 inside, and montant 2 relative cross bars 1 are upwards taken out; Make the spliced eye 3 hole wall extrusion elastic 8 of cross bar 1 make the shell fragment distortion, when the spliced eye hole wall moves to U-shaped draw-in groove 9 positions, accomplish clamping.
