Description
Technical field:
The utility model relates to guardrail net, particularly relates to a kind of guardrail net that can prevent that guardrail net sheet is stolen.
Background technology:
In recent years, along with the high speed development of China's urban construction, guardrail net need to be used in increasing place, with the safety of guarantor unit's production and resident living.Existing guardrail net all comprises column, guardrail net sheet is connected with the column of its both sides by connecting bolt, but the situation that divider current net sheet is lost often has generation, burglar just can take off guardrail net after connecting bolt is unloaded, particularly, in the place that does not have security personnel to keep an eye on, the situation that guardrail net sheet is lost is more serious.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of guardrail net that prevents that guardrail net sheet from losing.
Above-mentioned purpose is achieved in that it comprises guardrail net sheet, the column at guardrail net sheet and its two ends links together by connector, described connector comprises front fastener and rear fastener, the middle part of front fastener and rear fastener is attached on column, the shape at front fastener and rear fastener middle part and the shape of column adapt, the two ends of front fastener are all provided with elongated hole, the two ends of rear fastener are also provided with elongated hole in fastener elongated hole place before corresponding, also comprise two cushion blocks, each cushion block is provided with screw, a cushion block is located between the front fastener and the elongated hole on rear fastener of left end, another cushion block is located between the front fastener and the elongated hole on rear fastener of right-hand member, two cushion blocks are all fixed on rear fastener, front fastener and rear fastener and cushion block link together by anti-theft screw, described anti-theft screw comprises screw body and circular screw terminal, the relative projection that is provided with two approximate quadrant shapes on circular screw terminal, and two two protruding horizontal edges, on same straight line, leave distance between two two protruding longitudinal edges.
The utility model has the advantages that: during installation, guardrail net sheet is arranged on column by connector, because connector is provided with anti-theft screw, on the circular screw terminal of anti-theft screw, two two protruding horizontal edges are on same straight line, between two two protruding longitudinal edges, leave distance, the spanner of the turn of the screw is inserted between two two protruding longitudinal edges, using these two longitudinal edges as stress point, by screw tightening, and while oppositely turning, due to without stress point, thus the screw of tightening can not be backed out, thus guaranteed that guardrail net sheet can not lose.
