Abstract

The utility model relates to a snap spring connecting structure for cross rods and vertical rods of a fence. The snap spring connecting structure solves the problems that: the assembly of the cross rods and the vertical rods of the traditional assembled fence is complicated and time-consuming, the cost is high, and the vertical rods are easily stolen. The device comprises hollow cross bars and vertical rods, wherein the upper and lower surfaces of the cross bars are provided with insertion holes, and the vertical rods are inserted in the insertion holes of the cross rods. The snap spring connecting structure is characterized in that: snap springs are fixedly arranged on the side walls of the vertical rods inserted inside the cross rods in a clamping way, and the parts of the snap springs positioned on the opposite side surfaces of the vertical rods are provided with spring pieces which expand outwards obliquely along the axis direction of the vertical rods; and the outer ends of the spring pieces are provided with corrugated clamping grooves, and the clamping grooves are connected onto the walls of the insertion holes of the cross rods in a clamping way. The cross rods and the vertical rods of the fence are fixed by the snap springs, the snap spring connecting structure is simple in structure, and convenient to install, and does not need additional tools in installation; and the snap springs are positioned inside the cross rods, and the anti-theft performance is good.

Description

The jump ring syndeton of a kind of fence cross bar and montant

Technical field

The utility model relates to the fence production technical field, the jump ring syndeton of particularly a kind of fence cross bar and montant.

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 jump ring syndeton of stolen fence cross bar and montant.

The utility model solves the technical scheme that its technical problem adopted: the jump ring syndeton of a kind of fence cross bar and montant; Comprise hollow cross bar, montant; The cross bar upper and lower surfaces is offered spliced eye; Montant is plugged in the cross bar spliced eye, is plugged on the inner montant lateral wall of cross bar and embraces folder and be fixed with jump ring, and the part that jump ring is positioned at the montant two relative side is provided with along the oblique flared shell fragment of montant axis direction; The outer end of shell fragment is provided with the draw-in groove of ripple type, and draw-in groove is connected on the hole wall of cross bar spliced eye.During assembling, montant is plugged in the process of cross bar spliced eye, because the jump ring shell fragment has elasticity; Shell fragment receives the extruding of spliced eye hole wall to internal strain, when the draw-in groove that is plugged into shell fragment aligns with the spliced eye hole wall, and the outside resilience of shell fragment; Draw-in groove clamping spliced eye hole wall is fixed, montant and cross bar installation.After the installation, because jump ring is fixed on the inner montant sidewall of cross bar, be difficult for being damaged, avoid stolen, jump ring is simple in structure simultaneously, and it is also convenient to install.

As preferably, said jump ring is the grooved of three sides of double team montant, and shell fragment is the extension of cell wall end, jump ring both sides.Jump ring is the grooved that cooperates with montant bar wall, and the jump ring part except that shell fragment can be fitted in the montant surface and fix.

As preferably; The bottom land and the montant of said grooved jump ring are fixed; Said montant is provided with two connecting holes, and length is consistent between the distance between the connecting hole and the jump ring two ends, and bottom land one end of jump ring is provided with the block tongue on plane; The other end is provided with inside bending, rubber-like V-arrangement dop, and block tongue and V-arrangement dop match respectively at two connecting holes of montant.Block tongue inserts in one of them connecting hole; Then the V-arrangement dop is pressed into and accomplishes the fixing of jump ring and montant in another connecting hole, need not extra erecting tools, and jump ring can be processed separately, transport; To directly assemble the assembling simple and fast in the erecting bed.

As other fixed form, said jump ring and montant adopt screw.

As preferably, the spliced eye clamping of the shell fragment of said jump ring and cross bar bottom surface, the spliced eye of cross bar end face and montant bar wall match, and between cross bar end face spliced eye and montant bar wall, are provided with waterproof apron.The fence multidigit is in the open air, so being connected of montant and cross bar upper surface need adopt waterproof apron to carry out waterproof, and the structure of jump ring clamping is arranged on the cross bar soffit, when strengthening theftproof performance, do not influence waterproof work.

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

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 jump ring syndeton of montant; Comprise cross bar 1 and montant 2; Cross bar 1 upper and lower surfaces offers the spliced eye of mutual alignment respectively; Montant 2 is plugged in the spliced eye of cross bar 1, is provided with waterproof apron between the spliced eye 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 jump ring 3 to connect and fix.

Jump ring 3 structures are as shown in Figure 2, and jump ring 3 adopts stainless steel material to process, and jump ring 3 is a grooved, and the oblique respectively abduction open form in the end of two cell walls becomes shell fragment 4, and the outermost end ripple type of shell fragment 4 is folding, form draw-in groove 5 in the outside, shell fragment 4 ends; The bottom land of jump ring 3 an and shell fragment end in the same way is the V-arrangement dop of inside bending, rubber-like, and the other end is a plane block tongue 7.
