Abstract

The utility model relates to a theft-proof fence, comprising a guiding rail (1) needing to be fixed on a windowsill and a plurality of column bodies (2) which are integrally connected by coupling sheets (3) to form a telescopic movable fence. The utility model is characterized in that two ends of each of the column bodies (2) are extended in the inner part of the guiding rail (1), the guiding rail (1) has a star-shaped cross section, and the movable fence is provided with a locking device. The guiding rail (1) and the column bodies (2) of the utility model are made of steel plastic tubes as components, and the utility model having the advantages of simple structure, beautiful appearance, effective rust prevention, high safety, convenient operation and optional opening can adapt various accidents.

Description

A kind of burglar bars

The utility model relates to a kind of device for building, especially conveniently is used in a kind of burglar bars of door and window.

Along with a large amount of of labouring population are flowed, social security has become the hot issue that the people pays close attention at present, and the family door will be installed security door, and window will be installed burglar bars.This burglar bars generally all is hard-wired iron bars of outstanding window or balcony, this anti-theft measure is relative to safety, exists suitable defective, and is quite coarse as outward appearance, after particularly using a period of time, in a single day the serious and southern plastic-steel door and window that quite generally uses now of corrosion problem does not match, and secondly is as having unexpectedly incident in the building, as fire, indoor occupant can't be escaped from from window, and the fire fighter also can't enter from window, thereby produces new unsafe factor.Be exactly to steal molecule can utilize above-mentioned iron bar to enter the indoor of last layer resident family in addition, become the stealing molecule and can support the instrument of utilization, and produce new social contradications.Be that its life-span is short at last.

Goal of the invention of the present utility model is to disclose a kind of simple in structure, safety good, outward appearance is beautiful, the life-span is long burglar bars.

Realize that technical solution of the present utility model is as follows, comprise the guide rail that needs on the fixing windowsill, many cylinders are connected as a single entity by plate and constitute telescopic movable grid, and key is that guide rail inside is all stretched at the cylinder two ends, the section configuration of guide rail is a shape, and movable grid are provided with locking device.Guide rail of this product and cylinder can adopt steel-plastics composite pipe to make, and guide rail can horizontal positioned during installation, also can vertically place, and corresponding cylinder then is plumbness and level, to adapt to various installation requirements.

The utility model is simple in structure, and insert in the guide rail at the cylinder two ends, and have the plate activity to be connected as a single entity between the cylinder, so overall performance is good, can effectively resist big active force, is out of shape very little.Because adopt steel to mould pipe as member, outward appearance U.S. can effectively prevent corrosion, adds and is provided with locking device, security performance is also guaranteed, and easy to use, can arbitrarily open, and can adapt to the generation of various contingencies.

Provide specific embodiment of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of first embodiment of the present utility model.

Fig. 2 is the structural representation of second embodiment of the present utility model.

Fig. 3 is the A-A cut-away view at the guide rail position of Fig. 1 and Fig. 2.

See also Fig. 1-Fig. 3, the structure of specific embodiment of the utility model is as follows: comprise the guide rail 1 that need be fixed on the windowsill, many cylinders 23 are connected as a single entity and constitute telescopic movable grid in flakes by connection, between the plate 3 and between plate 3 and the cylinder 2 by pin 4 flexible connections.Plate 3 can be rotated around pin 4, so movable grid conveniently telescopic, and key is the inside that guide rail 1 is all stretched at the two ends of cylinder 2.When this movable grid stretch, slide in guide rail 1 in the both ends of cylinder 2, and under less distortion, cylinder 2 can't be overflowed in guide rail 1, and also there is the effect of blocking the end of 1 pair of cylinder 2 of guide rail simultaneously, the distortion of restriction cylinder 2.The section configuration of guide rail 1 is a shape, movable grid are provided with locking device, described locking device is to establish a dead bolt 5 on a cylinder 2, dead bolt one end is fixed on the cylindricality 2, the other end has a through hole 6, there is a through hole that can allow dead bolt 5 pass through at corresponding dead bolt 5 places on can contacted cylinder after another moves, as shown in Figure 1, when two movable grid are closed together, dead bolt stretches out by another cylinder 2, on the through hole 6 of dead bolt 5, can hang a padlock, locking activity grid then, described locking device is to fix a dead bolt 5 on cylinder 2, is provided with a hard-wired lock body 7 (common spring lock or coded lock) on another frame that is fixed on the body of wall, when movable grid were closed, dead bolt 5 was with the lock body effect and locking activity grid.Be the easy mobility of the safety of further raising activity grid, being provided with cylinder 2 at the both ends of cylinder 2 is the rotating runner 8 of the heart, this runner 8 is inserted in the inner chamber of guide rail 1, when moving movable grid, runner 8 rolls on the one hand and between the inner chamber wall of guide rail 1, on the one hand cylinder is played the effect of location, move reliable and stable, moreover fixing runner 8 with playing suitable inhibition, has humidification to safety when cylinder 2 distortion.
