Description
Technical field
The utility model relates to building anti-theft technique apparatus field, is specifically related to a kind of anti-theft device for leader.
Background technology
Leader is that the indispensability of multilayer high-rise building is implemented, also be the main instrument that utilizes of break-ins case criminal house lead in, as unshielded measure, resident's the person and property safety can constantly suffer great harm, and current most communities all exist following similar serious problems:
1, when outside each community, enclosure wall is constructed, not only all use inferior materials and turn out substandard goods, and outer enclosure wall height is generally too low: highly generally all at 1.8 meters to 2.4 meters, therefore the cast iron fence of enclosure wall is come off once prizing by burglar.Enter community and wantonly commit theft and created extremely rare opportunities for burglar takes advantage of in the dead of night by prizing bad enclosure wall.
2, outside residential quarter, on enclosure wall top, all there is no an illuminating lamp, this also enters community and wantonly commits theft and created extremely rare opportunities for burglar takes advantage of in the dead of night by prizing bad enclosure wall.
3, all serious deficiencies of the safety lighting at residential quarter night, its main cause is in cast iron steel pipe or in cast iron basin, seriously to have affected the release of light by all buried the bulb of illumination, causes the release rate of light only to account for the 15-30% of original light.
For above-mentioned serious problems; Chinese patent CN201704892U discloses a kind of downpipe climbing prevention umbrella, and this unit protection effect is not strong, establishes short distance protection; as long as criminal manages to cross this Duan Ze and can not play any protective action, even for criminal provides foot-operated place.
Chinese patent CN301969653S discloses a kind of antitheft thorn (cast); this unit protection scope is more comprehensive, but antitheft thorn is installed the stress scarce capacity of rear its pricker in pipeline direction, and is easy to hang thing; criminal easily uses instrument that it is floating, makes it lose anti-theft capability.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art, and a kind of anti-theft device for leader is provided, by the grid framework with steel thorn in leader place spiral-lock, to stop the climbing person of leader.
The realization of the utility model object is completed by following technical scheme:
A kind of anti-theft device for leader, it is characterized in that: described anti-theft device main body is a grid framework, described grid framework has a bearing, profile shape and described leader gabarit form fit in described bearing, described bearing gabarit is fixedly installed some steel thorn sticks, described bearing gabarit surface is fixed in one end of described steel thorn stick, and the other end is equipped with steel thorn, and some described steel thorn sticks are connected and fixed and are formed described grid framework by some connecting rods.
Grid framework is semicircle framework, wide semicircular arc in described bearing.
The center of circle of described semicircle framework is concentric with the interior wide center of circle of described bearing.
The end, two ends of described bearing has fixing fin.
Described some steel thorn sticks outwards radially distribute from described bearing gabarit surface.
Some described connecting rods are for being circular-arc.
The end, two ends that is positioned at the described connecting rod of outermost has fixing fin.
Described anti-theft device also comprises a steel gill net, and described steel gill net is positioned at described grid framework top.
The utility model has the advantages that: can prevent the generation of the situation of stealing, the pilferage incidence of cases at national night is reduced in a large number; Apparatus structure advantages of simple, is convenient to installation and maintenance; Apparatus cost is cheap, is convenient to popularize.
Brief description of the drawings
Fig. 1 is top view of the present utility model;
Fig. 2 is use structural representation of the present utility model;
Fig. 3 is mounting structure schematic diagram of the present utility model.
Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
As Figure 1-3, in figure, mark 1-10 is respectively: grid framework 1, steel thorn stick 2, steel thorn 3, connecting rod 4, bearing 5, fixing fin 6, interior wide 7, leader 8, steel gill net 9, diagonal brace 10.
Embodiment: as shown in Figure 1, be a grid framework 1 for the anti-theft device main body of leader in the present embodiment, this grid framework 1 is by bearing 5, connecting rod 4 and steel thorn stick 2 is assembled forms.The wherein interior profile shape of bearing 5 and leader 8 gabarit form fit, and its end, two ends has respectively outside fixing fin 6, in order to be fixed in the outer surface of wall that leader is installed, interior wide 7 is the position of passing of leader 8, makes the local body of the leader 8 passing from interior wide 7 be stopped by bearing 5 and cannot climb.Along the radial steel thorn stick 2 that is evenly fixedly installed of bearing 5 gabarit circular arc direction, one end of steel thorn stick 2 is fastened on bearing 5 gabarit surfaces, and the body of rod stretches out from bearing 5 gabarits, its elongated end assembling steel thorn 3.Steel thorn stick 2 is circular-arc connecting rod 4 by two and is connected and fixed and forms grid framework 1, wherein connecting rod 4 play prevent climbing effect simultaneously, also for steel thorn stick 2 provides support, avoid its by climbing person break curved, fracture.In order to improve the support strength of connecting rod, be also respectively arranged with fixing fin 6 in the end, two ends of outermost connecting rod 4, can be fixed on outer surface of wall.
The present embodiment is in the specific implementation: as shown in Figure 2, the fixing fin 6 in both sides by bearing 5 and connecting rod 4 is fixed on by grid framework 1 exterior wall surface that leader 8 is installed and (is generally positioned at height lower, for example one, between second floor), ensure leader 8 interior wide 7 of the bearing 5 of just in time boring a hole simultaneously.As shown in Figure 3, in order to improve the firm degree of grid framework 1, two diagonal braces 10 are thereunder installed, one end of diagonal brace 10 and steel thorn stick 2 assembly connections, the other end is fastened on exterior wall surface.Depend on said structure, thereby the leader 8 of interior wide 7 tops is blocked and is protected by grid framework 1, make lawless people cannot cross grid framework 1 again from leader 8 free-hand climbing enter in resident family.
As shown in Figure 2, in order to improve safety factor, the body surface of leader 8 that can also be above interior wide 7 is wound around steel gill net 9, thereby has stopped the possibility of free-hand climbing completely.If be stripped from or remove for fear of steel gill net 9, the lower end of steel gill net 9 can also be wound on grid framework 1, both connect and compose integrative-structure, to obtain best result of use.
Interior wide 7 the center of circle of the center of circle that is circular-arc connecting rod 4 and bearing 5 is concentric, makes the load of whole grid framework 1 steady, avoids the tensile strength causing because of eccentric structure to decline.Bearing 5 can be set to the integrative-structure forming with grid framework 1, to increase the tensile strength of framework.
Beyond the firm degree of guarantee anti-theft device itself, consider the service life of anti-theft device, avoid it cause loosening because service life is long or damage, fixing fin 6 can select the expansion bolt of stainless steel to be fixed on outer wall body, same, steel gill net 9 also can be selected the steel gill net of stainless steel.
