Abstract

The utility model relates to a combined palisade of spring and safety bolts, which comprises cross rails (2) connected by piles and pillars (1), vertical rails (3) connected with the cross rails (2) through bayonet joints (8). The utility model is characterized in that the bayonet joints (8) are spring collets, which are in U shape. At the two sides when a spring collet opens an angle Alpha, a notch is provided (14). When a vertical rail is inserted into a hole (11) of a cross rail, the spring collet will spring open automatically, by pushing lightly the vertical rail (3), the spring collet will snap on the pipe wall of round hole (7) of the vertical rail (3), so as to control the movement of the vertical rail (3) in one direction. The other spring collet of the same vertical rail (3) is mounted in reverse direction, so that the vertical rail (3) will not move in another direction. Two spring collets (8) can be installed in one cross rail in reverse directions to control that the cross rail can't move and be pulled out.

Description

Spring breaker bolt modular fence

Technical field:

The utility model is relevant with spring plug-in steel pipe fence.

Technical background:

Existing spring plug-in steel pipe fence is assembled by horizontal bar and the clamping of perpendicular hurdle, when Spring Card and the clamping of perpendicular hurdle, because not exclusively perpendicular to horizontal bar, under external force, potential safety hazard appears in the phenomenon that happens occasionally, and is also easily robbed or burgled.When the hurdle is erected in the Spring Card insertion, because the Spring Card structure design is unreasonable, very easily scratch perpendicular hurdle inwall, bring influence application life for perpendicular hurdle, the steel pipe that fence uses is square steel pipe, and the hole majority is a square, from the mechanics of materials and structural mechanics as can be known, the stress concentration phenomenon is more outstanding, and mechanical strength is a greater impact, and all should avoid adopting square tube, hole in the general design as far as possible.Under the situation of same wall thickness, the inscribed circle pipe of a square steel pipe and same square steel pipe, its mechanical strength is identical, can economize on material 21.5% or intensity in other words and improve 21.5%

The content of utility model:

The purpose of this utility model is, overcomes the design impropriety of existing fence, provides a kind of structure simpler, and it is easier to process, and cost is cheaper, I﹠ M more convenient (using special tool), safe and reliable spring breaker bolt modular fence.

The utility model is achieved in that

The utility model is a spring breaker bolt modular fence, comprise the perpendicular hurdle (3) that horizontal bar (2) that pile (1) connects and horizontal bar (2) are connected by shackle member (8), it is characterized in that said shackle member (8) is Spring Card, Spring Card is the U type, Spring Card opens the both sides jagged (14) of an angle [alpha], when the hole (11) that perpendicular hurdle inserts horizontal bar (2), Spring Card can automatically spring open.Touch on the tube wall of circular hole (7) that perpendicular hurdle (3) Spring Card can be stuck in perpendicular hurdle (3), controlling (3) directions in perpendicular hurdle moves, another Spring Card rightabout on same perpendicular hurdle (3) is installed, perpendicular hurdle (3) can not be moved to other direction, realized that rightabout is installed two Spring Cards (8) in the same horizontal bar, the perpendicular hurdle (3) of control can not move up and down or extract out.

Pile (1), horizontal bar (2) and perpendicular hurdle (3) are round steel pipe, and horizontal bar (2) also can adopt rectangular steel pipe.Horizontal bar (2) is elliptical aperture or circular hole with the mating holes (11) on perpendicular hurdle (3), forms by mould punching, when the bottom ellipse on perpendicular hurdle (3) needs, forms with touching the tool compacting.

On horizontal bar (2) and perpendicular hurdle (3) mating holes (11), plastic washers (4) is arranged, and it is shaped as circle or ellipse, and the cambered surface that cooperates with pipe arranged, it is characterized in that the rounded washers diametric(al) has a symmetrical breach (15), at oval short-axis direction one symmetrical breach (15) is arranged equally, its gap width is getting final product by the Spring Card extension.

On the mating holes (11) of horizontal bar (2) and perpendicular hurdle (3) decoration (6) is arranged, it is characterized in that material is plastics, convertible shape of all kinds, decoration (6) two ends up and down has ovallized column (16) ovallized column (16) to be inserted in the hole (11) of horizontal bar (2), by the breaker bolt (17) on the horizontal bar (2), fixing decoration (6) can not deviate from, and ovallized column (16) prevents that decoration from rotating simultaneously.

Two long perpendicular hurdles (19) are arranged on every fence, it is characterized in that said horizontal bar (2) and long perpendicular hurdle (19) fix with breaker bolt by the hole (9) of horizontal bar (2) and the hole (7) on perpendicular hurdle (3), while two bottoms, perpendicular hurdle and basis join, and improve the flexural strength of horizontal bar (2).Thereby reduce the cross dimension of horizontal bar (2).

Pile (1) is connected with breaker bolt by connector (18) with horizontal bar (2).Be characterised in that said connector (18) inserts the hole (5) of pile (1), the hole (23) of pile (1) and the hole (12) of connector (18), connect with breaker bolt (17), the hole (10) of horizontal bar (2) is connected with breaker bolt (17) with the hole (13) of connector (18).

Spring Card is to bend with stainless steel wire and stainless steel band or punching out forms with spring.

Figure 24 erects hurdle point punching out or uses moulding.

The utility model and existing various fence are compared, and structure is simpler, and material is more saved, the Spring Card more reasonable structure is difficult for wiping and draws perpendicular hurdle inside pipe wall, improves antirust ability, packing ring prevents that perpendicular hurdle and horizontal bar from abrading mutually, because the more anti-theft bolts of use, robbed or burgled property are littler.
