The utility model is characterized in that a plurality of audible devices are arranged on the ball frame; when children scramble, metal sheets arranged on the rope net are touched, and music or animals' bleats can be sent out to increase the children's pleasure; each of the audible devices comprises a single song integrated circuit, a triode transistor VT1, VT2, VT3, a resistor R and a loudspeaker; the metal sheets are connected with a base electrode of the VT1; the emitter electrode of the VT1 is connected with a base electrode of the VT2 whose emitter electrode is connected with a 2 foot of the single song integrated circuit and connected with the positive end of a power supply through the resistor R; the base electrode of the VT3 is connected with a 3 foot of the single song integrated circuit; a collecting electrode is connected with the loudspeaker.

Description

Spherical climbing net frame

The utility model relates to a kind of children's play climbing frame, particularly relates to a kind ofly having acoustic children and climbing frame.

Children enjoy a lot the climbing recreation, and the present existing rack that supplies children to climb recreation is a square monkey frame.Made by iron pipe fully, children accidentally, easily damage when climbing.

The purpose of this utility model is at the problems referred to above, and a kind of children that damage that are difficult for are provided, and has acoustic spherical climbing net frame.

The purpose of this utility model adopts following technical proposals to realize, that is:

Spherical climbing net frame comprises the spherical frame, bearing and a plurality of PA-system that are made of a plurality of spherical iron pipes.On each spherical iron pipe of spherical frame a plurality of iron hoops are arranged, the horizontally disposed nonelastic netting of multilayer is arranged in the spherical frame, netting is fixed on the spherical steel pipe by iron hoop.Spherical frame is supported by bearing, and the spherical iron pipe of each of spherical frame is connected with the contact site solid welding of bearing.PA-system comprises sheet metal (or the thick electric wire of metal), single music integrated circuit, touch switch circuit, amplifying circuit, loudspeaker and 4.5V dc source.Touch switch circuit is by triode VT ₁, VT ₂, resistance R is formed, triode VT ₁Base stage connect sheet metal (or the thick electric wire of metal), its colelctor electrode connects power supply negative terminal, emitter stage meets triode VT ₂Base stage, triode VT ₂Colelctor electrode connect power supply negative terminal, 2 pin of the bent music integrated circuit of emitter stage order, and connect power positive end by resistance R.1 pin of single music integrated circuit connects power supply negative terminal, and 3 pin meet triode VT ₃Base stage, 5 pin connect power positive end.Amplifying circuit is by triode VT ₃, capacitor C forms triode VT ₃Emitter stage connect power positive end, colelctor electrode connects loudspeaker.One termination power anode of capacitor C, another termination power supply negative terminal.A plurality of PA-systems are separately positioned on the suitable location of spherical climbing net frame, with the triode VT of each PA-system ₁The sheet metal that is connected of base stage, be separately fixed on the netting of spherical frame.

The single music integrated circuit can adopt KD9300, LH9300, HFC9300 type etc., can send the single music, or simulates the animal cry.

The utility model can be climbed it on for surplus 10 children therein simultaneously, also can lie on the netting, also can ride on the spherical iron pipe support or steps on netting and play.When children in when climbing, when finger was run into sheet metal, children's human body sensing made VT ₁, VT ₂Conducting, and make VT ₂The emitter stage current potential raises, the work that is triggered of single music integrated circuit, and the output electronic audio signal is through VT ₃Amplify, promote sound horn, can be melody or animal cry, increase the enjoyment of entertainment for children.At this moment, even children's hand leaves sheet metal, melody does not stop, till this section melody has been played.When children's hand does not have contact metal film M, VT ₁, VT ₂Be in cut-off state, the single music integrated circuit is not worked.

The utility model is attractive in appearance, be not afraid of wind and weather again, so it can be arranged on park, biotope, skyscraper sub-district, parks at the intersections etc. and locate, and also can be arranged in the emporium, attracts the head of a family to be with entertainment for children, reaches the purpose that increases client.The utility model is in light weight, dismounting and convenient transportation.

Fig. 1 is the structural representation of a kind of embodiment of the present utility model, and Fig. 2 is the circuit theory diagrams of PA-system, and the utility model is described in further detail below in conjunction with accompanying drawing.

Spherical climbing net frame, spherical frame 3 and 6 PA-systems of comprising bearing 1, constituting by 6 spherical iron pipes 2.On the spherical iron pipe 2 a plurality of iron hoops 5 are arranged.7 layers of netting 6 are arranged in spherical frame 3, and netting 6 is fixed on the spherical iron pipe 2 by iron hoop 5.Spherical frame 3 is arranged on the bearing 1, and the spherical iron pipe 2 of each of spherical frame is connected with bearing 1 touching position solid welding, but also rivet clasp connects.6 PA-systems are separately positioned on the suitable location on the spherical frame 3, and PA-system comprises sheet metal 4, single music integrated circuit 9, touch switch circuit, amplifying circuit, loudspeaker 7 and 4.5V battery 8.Single music integrated circuit 9 is HFC9300, and touch switch circuit is by triode VT ₁, VT ₂, resistance R forms VT ₁, VT ₂Be triode 9014, R is 5.1K Ω.VT ₁Emitter stage meet VT ₂Base stage, VT ₁Colelctor electrode connect power supply negative terminal, sheet metal 4 and VT ₁Base stage connects, and sheet metal 4 is fixed on the netting 6.VT ₂Colelctor electrode connect power supply negative terminal, its emitter stage connects 2 pin of HFC9300, and connects power positive end by 5.1K Ω resistance R.1 pin of HFC9300 connects power supply negative terminal, and 3 pin meet VT ₃Base stage, 5 pin connect power positive end.Amplifying circuit is by triode VT ₃Form VT with capacitor C ₃Be triode 9013, its emitter stage connects power positive end, and colelctor electrode connects loudspeaker 7, and loudspeaker 7 resistance are 8 Ω, a termination power anode of capacitor C, another termination power supply negative terminal.C is 22 μ method electric capacity.
